Digital radiography system


Digital radiography is a form of X-ray imaging, where digital X-ray sensors are used instead of traditional photographic film. Advantages include time efficiency through bypassing chemical processing and the ability to digitally transfer and enhance images. Also less radiation can be used to produce an image of similar contrast to conventional radiography.
Instead of X-ray film, digital radiography uses a digital image capture device. The gives advantages of immediate image preview and availability; elimination of costly film processing steps; a wider dynamic range, which makes it more forgiving for over- and under-exposure; as well as the ability to apply special image processing techniques that enhance overall display of the image.
Essential part--digital X-ray sensors --Detector

There are two major variants of digital image capture devices: flat panel detectors (FPDs) and high-density line-scan solid state detectors. FPDs.
Digital dental radiography comes in two forms: direct, that connect directly to the computer via USB and provides immediate images, and indirect (photostimulable phosphor plates, or PSP) which uses plates that are radiated and then digitally scanned.
Direct digital sensors represent a significant initial investment, but in addition to the convenience of digital images, provide instant images that can reduce the time the patient spends in the dental chair. They also reduce the need for the constant purchase of film and the necessary development chemicals. Early systems used CCD sensor technology, but changed to CMOS sensors following their introduction in early 1998-9.
Indirect digital imaging utilizes a reusable plate in place of the film. After X-ray exposure the plate (sheet) is placed in a special scanner where the latent formed image is retrieved point by point and digitized, using laser light scanning. The digitized images are stored and displayed on the computer screen. This method is halfway between old film-based technology and current direct digital imaging technology. It is similar to the film process because it involves the same image support handling but differs in that the chemical development process is replaced by scanning. This is not much faster than film processing and the resolution and sensitivity performances are contested. PSP has been described as having an advantage of fitting within any pre-existing equipment without modification because it replaces the existing film; however, it includes extra costs for the scanner and replacement of scratched plates.

Clinical lab device Blood Coagulation


The first Blood Coagulation Analyzer was invented by Kottman in 1910, which to reflect the plasma solidification of time through the determination of blood clots viscosity changes.
So you may want to know what Blood Coagulation is. Coagulation is the process by which blood forms clots. It is an important part of hemostasis, the cessation of blood loss from a damaged vessel, wherein a damaged blood vessel wall is covered by a platelet and fibrin-containing clot to stop bleeding and begin repair of the damaged vessel. Disorders of coagulation can lead to an increased risk of bleeding (hemorrhage) or obstructive clotting (thrombosis). Coagulation is highly conserved throughout biology; in all mammals, coagulation involves both a cellular (platelet) and a protein (coagulation factor) component.The system in humans has been the most extensively researched and is therefore the best understood.
Coagulation begins almost instantly after an injury to the blood vessel has damaged the endothelium lining the vessel. Exposure of the blood to proteins such as tissue factor initiates changes to blood platelets and the plasma protein fibrinogen, a clotting factor. Platelets immediately form a plug at the site of injury; this is called primary hemostasis. Secondary hemostasis occurs simultaneously: Proteins in the blood plasma, called coagulation factors or clotting factors, respond in a complex cascade to form fibrin strands, which strengthen the platelet plug
After 70 s, due to mechanical the development of the electronic industry, make all types of automatic blood clots instrument has come out.
In the 80 s, because developing substrate method came out and was applied to the blood clots detection, make automatic Blood Coagulation not only can carry on the general screening tests outside, also can undertake blood coagulation anticoagulation fibrinolysis system single factor detection.
As a manufacturer, we delicate to develop more advanced machine well applied in the medical filed and do the best we can do to make contribution to the human society.

The Significance of C-arm X-ray Machines in the Computer-assisted Virtual Fluoroscopy

The C-arm x-ray machine is divided into small C-arm X-ray machine, medium-sized C-arm and the large c-arm. No matter what kind of c-arm x-ray machine medical equipment, computer-assisted work. C-arm x-ray machine in the clinical significance of computer-assisted virtual fluoroscopy where the performance?

X-ray during surgery is a valuable tool in the surgery. Intraoperative scanning assisted positioning of the X-ray examination of the relative position of clear surgical medical devices and patient anatomical structures and improve surgical precision. Reduce the exposure range of the surgery. Computer-assisted virtual fluoroscopy enables the surgeon to the observed changes in the structure of the patient's anatomy in real time, in order to help them carry out the insertion operation of the surgical instruments.


Digital X-ray machine is an essential tool of the surgeon, but it still has its limitations. Mainly in the following three aspects: during the process of perspective, patients, doctors and perspective of the operator and easy exposure to X-ray radiation, caused by occupational radiation. We can only in a plane X-ray fluoroscopy, can only be observed in the single-plane view. When the need to observe the position of surgical instruments in the multi-plane view. Surgical procedures need to be constantly repeated adjust the location of the C-arm scan positioning, resulting in surgery to interrupt and time-consuming, and increase the difficulty of doctors operating surgery. C-arm x-ray machine out of or into the surgical area, will increase the potential for patients with wound infection.


In contrast, c arm x ray machine computer-assisted virtual fluoroscopy has the following advantages: simple operation, high accuracy, does not require pre-operative CT scan. It during surgery perspective imaging and computer-aided surgical navigation software to provide a real-time, multi-dimensional imaging, and access do not need to increase the additional radiation exposure to patients and doctors at the expense doctors do not move the perspective of the c-arm x-ray machine can be obtained orthogonal and inclined three-dimensional perspective.

Three Factors of Blood Gas Analyzer to Detect Blood Gas PH Values

Combined with the advantages of the electrolyte analyzer, blood gas analyzers(developed into a blood gas electrolyte analyzer) are medical devices used in clinical blood gas acid-base balance . Obtained after the detection of the blood gas analyzer, blood gas acid-base balance mainly by three factors, as follows:
Blood gas analysis detected bleeding gas acid-base balance is also the body a lot of balance one of its core is [H +] concentration of pH value, the normal value of 7.4 (7.36-7.44). It is mainly affected by three aspects of adjustment: kidneys regulate the breathing regulator and the body buffer system.
Kidneys regulate
The kidneys regulate through renal excretion and absorption of H + and HCO3-to regulate the H + excess is excreted through the urine, and H + is less row or even absorption from the urine back in order to maintain normal blood pH value.
Respiratory regulation
Respiratory regulation through the breath exhaled CO2 to regulate, CO2 too much then exhaled, too little breath less.
Buffer system in the body

Bicarbonate - carbonate buffering system

Phosphate buffer system
Protein buffer system is called a buffer system? As the name suggests is to play a buffer role in the system. Such as to make high-speed car suddenly stopped, which could make cars and car people can not afford, so a special device to let the car slow down to such a device could be called "buffer system". The body of [H +] concentration, if a sudden change quickly, then people will not stand, so you need appropriate to make it slow down. The basic principle is this: H + + HCO3-= of H2CO3 = H2O + CO2 [H +] [HCO3-] / [H2CO3] = Ka-(Ka is a constant, fixed under certain conditions, conditions such as temperature pressure etc.)
Blood gas analyzer measured by various indicators and their significance. Into acidosis and alkalosis, the pH changes, pH decreases acidosis and alkalosis, pH increases can be divided according to the primary cause of respiratory and metabolic. According to various indicators can be divided into respiratory and metabolic. Metabolic indicators: standard bicarbonate, buffer base, base excess, anion gap; breathing index: PCO2, actual bicarbonate.

Medical X-ray Machine has Five Functions

Medical x-ray machine is also called the x-ray instrument. X-ray machine used in clinical radiology has five functions:
Penetration of medical x-ray machine
Penetration of the X-rays through the material without being absorbed. The function of the medical x-ray penetration generally visible through the material. Visible because of its longer wavelength photons energy is very small, when hitting the object is reflected, most of the absorbed substances, not through the object; X-ray is not, pharynx and its wave length, energy large, according to the material, only part of the material absorbed through the atomic gap through demonstrated a strong ability to penetrate. X-ray penetration capacity of substances and x-ray instrument photon energy, the shorter the wavelength of X-rays, the greater the photon energy, the stronger penetration. Penetration of X-rays with matter density is related to the density of the material, X-ray absorption through the less; density, absorb less through. The difference in absorption of this nature can distinguish different densities of bone, muscle, fat and other soft tissue areas. This is the X-light perspective and photography physical basis.
Medical x-ray electromechanical away from the role of
Material by the irradiation of medical x-ray machine, so that the atomic electrons from the atomic orbitals, this effect is called ionization. In the photoelectric effect and scattering process, the photoelectron and the recoil electron from its atomic process called ionization, the photoelectron or the recoil electron in the road and other atomic collision, hit in the atomic escape e-called secondary ionization. In the solid and liquid. Positive and negative ions after the ionization will soon be complex, difficult to collect. But forget the gas collected from the charge is very easy to use ionization charge determination of X-ray exposure: X-ray measuring instruments precisely made according to this principle. Due to ionization, so that gas can conduct electricity; of certain substances can react chemically; organic body can induce a variety of biological effects. Ionization is the basis of X-ray damage and treatment.
Fluorescence role of medical x-ray machine
X-ray wavelength is very short, so it is not visible. Exposure to certain compounds such as phosphorus, platinum cyanide, barium, zinc sulfide cadmium, calcium tungstate, etc., due to ionization or excitation of atoms in the excited state, the atoms return to ground state, due to the level transition of the valence electrons radiation to visible light or ultraviolet light, which is fluorescent. The x-ray machine so that the role of the substances fluorescence called fluorescence role. The fluorescence intensity of X is proportional to the amount of light. This role is the basis of X-rays applied to the perspective. Use of this fluorescence role in the X-ray diagnostic work can be made of the screen, intensifying screens, and image enhancement in the input screen and so on. Screen used as a perspective to observe the X-ray intensifying screens used for photography through the images of human tissue to enhance the film photosensitive.
Thermal effect of medical x-ray machine
X-ray absorbed by the material can be transformed into heat energy, so that the object temperature, which is the thermal effect.
Medical x-ray machine interference, diffraction, reflection, refraction
These effects with visible light. X-ray microscope, the wavelength determination and material structural analysis has been applied.

Abbott blood cell analyzer supporting reagent

Blood analyzer reagent has a lot of brands, such as abbott blood cell analyzer supporting reagent, Kurt reagent etc.

Blood cell analyzer reagent forauto hematology analyzer to the accuracy of the results is very important, in two, three classification of machine, fixed terminus of the equipment to the requirements of the diluent is very strict, directly affect the classification of white blood cells and red blood cell press and average volume of counting, directly reflects the histogram, leukocyte histogram can't pull can form mononuclear cells increased, classification inaccurate, the same red blood cell and platelet graphics is also good, influence to HCT.

RDW PDW, PCT and so on the results of accurate, serious still can cause hemoglobin precipitation and combining cause hemoglobin inaccurate. In the floating terminus of machine, also can also affect, no more natural inaccurate classification results for hemolytic agent bad influence for classification and graphics are of great influence, and the accuracy of hemoglobin has a very big impact, do not think that by adjusting the scaling factor can make up for the defects of medical reagent quality.

With five classification blood cell counter analyzer diluent role for some reduced, some but because of the need to join sheath fluid and become more complex, like abbott blood cell analyzer need sheath fluid, diluent, hemolysis agent and cleaner, general staining five classification machine in the classification of the lymphatic, neutral, monocyte, acidophile divided into a detection channel, through the acidophilic reagent and diluent to classification, therefore 4 classification inaccurate or simply not out, you should first consider the reagent, change new batch number or manufacturers see again, for sheath flow system cleaning is also very important (sheath flow pool, sheath flow power distribution system, mixed tending system need to check), what is more need to gain or sensitivity adjustment and laser emission accept distance and Angle adjustment, these are not general engineer can master.

Basophilic cells counting general in a separate channel, some of the total number of white blood cells counters combined with determination, if basophilic cells or total number of white blood cells, and the first to be check this reagent and then count channel.

Failure Analysis of Blood Gas Analyzer's High-voltage Problem and Printer Problem

WhenBlood gas analyzer supply voltage suddenly increase and Figures in the display disappear as well as printer problem during operation, what should we do?
Failure a blood gas analyzer power supply voltage a sudden increase in the figures disappear on the screen. The investigation is slow melting fuse has blown. Put on the insurance to boot, sustained alarm, the display did not make the fault tips.
Maintenance: Remove all circuit boards, double-check whether the component color charred and cracked, and the measuring circuit with a multimeter and found that the exception is taken down to a single measurement. Check the Department of analog board breakdown, troubleshooting replacement.
Rush occasional moment of the power supply system, high pressure generated waves, caused by overload capacitor breakdown, because the local power energy crisis, power surge caused by line fault is more difficult to avoid. Prevention is the use of advanced power regulator device and install a regular and effective ground to minimize the harm.
Starting from the voltage increased: normal circumstances, current and voltage can be used sine wave, the anomalies current voltage change of the curve, there are two:
One is Qiufeng Bo, is characterized by a crest high and wide, contained in the energy;
The second is the sharp front wave is characterized by a crest high and narrow energy small. The first wave can be blocked by regulators or the insurance system will not cause failure; the latter wave voltage regulators and the insurance system does not recognize, resulting in the destructive effects of the first breakdown protection on the line capacitance, when re-boot then the blown fuse.
Failure two blood gas analyzers printer paper, unscrew the screws of the fixed printer with a multimeter measurement circuit and the motor part of the normal, turn the printer shaft, found gear loosening 2.carefully gear dial back test adjust the gears when the machine to the optimum position, with all-purpose adhesive fixed gear on the shaft, installed test machine can be dry.

Introduction of Microplate Reader Based on Monochromator Detection System

Microplate reader is a medical device used by the matching washer, then how does microplate's monochromator work?
Microplate monochromator principle of white light from the light source through the physical effects of different grating splitter through different slits to select different wavelengths of light to excite the sample. The same set of monochromator system used to process samples of the light emitted and passed to the detection system used to measure.
Microplate monochromator system has its own advantages, as follows:
   First, microplate reader, monochromator system is easy to use, using the software can be arbitrarily chosen detection wavelength. And filter systems do not need other attachments for operation and maintenance, at the same time do not need to spend time for a new experiment to choose the accessories and the appropriate wavelength.
The second reader of medical devices monochromator for spectral scanning, the identification of new fluorescent substance or the wavelength of migration in some analyzes. While the scan function is useful for many people, but also subject to certain restrictions, which is different microplate detection optics and spectrophotometer cuvette system for cuvette system excitation into a 90o angle between the beam and transmit channels for the optical path of the plate reader is not possible to reach this point of view, therefore, a higher detection microplate reader background, can not provide the detection level the required detection sensitivity and signal resolution.
Third, the flexibility of the microplate monochromator system, the advantages of easy for customers to accept. Because most of the elisa reader-based monochromator system price is higher than Microplate-based filter system, because they are seemingly more detection analysis.

The History of Streaming Hematology Analyzer

The development of first set of blood analyzer is as follows:
1930 Casperrsson and Thorell pioneered with the microscope the structure of the stained cells
1934 Andrew Moldaran began to design the use of liquid hanging a single red blood cell flow through the glass capillary by the photoelectric detector connected to the microscope to count and record each by a cell, since then, taken from the microscope to observe the development of quiescent cells by flow cytometry the first step.
1936 Caspersson et al. To introduce microscopic photometric surgery Mierophotometry), also known as the microstructure spectrophotometric technique (Microspectrophotometry) or cell photometric technique (Cytophotometry). Mechanical, optical and electrical components in order to achieve the transmitted light, reflected light interferometry, optical path difference and fluorescence, thus achieving on the microscope to distinguish the scope of small objects (such as in the ordinary microscope with cells, etc.) and quantitative measurement.
Albert Coons in 1940 invented the antibody labeling fluorescence techniques and the use of a combination of specific proteins within the fluorescein antibody labeled cells, creating a fluorescently labeled antibody medical equipment.
1947 Guclcer the use of laminar and turbulent flow principle to the development of smoke particles counter. The same year, Wallace Coulter invented Kurt principle, that the particles suspended in the electrolyte with electrolyte through the small hole tube, replace the same volume of electrolyte, in the constant current circuit, the resistance between two electrodes inside and outside the aperture tube the size and frequency of occurrence of transient changes in potential pulse, the pulse signal and the particle size and is proportional to the number.
The Perlong medical device manufacturers pointed out that the blood analyzer design based on this principle has so far not changed, the principle was patented in 1949.
1950 Caspersson invented the technology of the cells was detected by micro spectrophotometer in the ultraviolet (UV) and visible spectral regions.
Crosland-Taylor in 1953 to study the laws of Newtonian fluid flow in a circular tube, the tube axis of flow through the sheath liquid flow rate the faster the loading by the ability of the stronger and stronger fluid power aggregation . So the design of a flow chamber: the cell suspensions to be analyzed are concentrated near the tube axis of the flow through the outer layer is wrapped sheath liquid, the cell suspension and the sheath liquid in order to maintain high-speed laminar flow state of motion. Design and so the principle of automatic counter of the red blood cell optics, therefore, laid the technical basis of modern flow cytometry in the flow. That same year, Parker and Hutcheon developed a complete blood count device, a prototype of the streaming blood analyzer.
After the above theory, technology and the accumulation of experience, in 1953 Coulter has introduced the world's first streaming hematology analyzer-Coulter, Counter Model A

How to Achieve Blood Gas Analyzer's Quality Control, Calibration, Maintenance?

How to achieve blood gas analyzer's quality control, calibration, maintenance?
Quality control of medical devices to monitor blood gas analyzer should be every day for early detection and the exclusion of measurement errors, ensure accurate and reliable measurement results. Calibration is an analytical process, instrument calibration concentration and other indicators of test, the correlation detection state to adjust to achieve the best test accuracy and instrument state. Calibration requires two kinds of calibrators and two bottles of premixed gas, the instrument automatically performs quality control is the ultimate test calibration.
Anesthetic gas PO2 electrode, the value of anesthesia after the patient's PO2 will be disturbed, while the normal blood pH of PO2 measurement is not affected. After infusion of the patient, because the blood contains large amounts of liquid, easy to make the measurement of the pH affected. Blood samples taken from such patients should be tagged, this factor is taken into account so that the blood gas analyzer results. Blood may not be squeezed, due to tissue fluid mixing will seriously affect the measurement results. Blood retention time of less than 10 minutes at room temperature is appropriate. Measurements, when the testing room air bubbles, should be re-measured time.
Maintenance should be performed every day the first blood gas analyzer cleaning procedures used to get rid of the sediments of the testing department. Go protein procedures used to remove the detection of the Ministry of protein deposits, a week or not 100 samples executed once, but the recommendations do not specify other than high concentrations of hypochlorous acid, as this will greatly shorten the life of the electrode membrane, the membrane price expensive, not worth the candle. Troubleshooting is divided into a general exception record measurement of the exception record abnormal calibration records and internal error message.

The Two Principles of Working Electrodes of Electrolyte Analyzer

Carbon dioxide partial pressure of the electrode and the partial pressure of oxygen electrode working principles in electrolyte analyzer are as follows:
Electrolyte analysis instrument medical device of carbon dioxide partial pressure electrode gas sensing electrode is a composite electrode of the pH glass electrode and silver - silver chloride electrode assembly together. The composite electrode contains carbon dioxide partial pressure electrode outside the buffer (including of NaHCO3-NaCl), and its pH electrode for blood carbon dioxide partial pressure change.
Electrolyte analyzer, medical equipment of the partial pressure of oxygen electrode, redox electrode, measurement of oxygen is based on the principle of electrolytic oxygen. Partial pressure of oxygen electrode by a platinum wire cathode and silver - silver chloride anode, known as the Clark electrode. The oxygen partial pressure in the test solution can make use of the electrode outer surface of the partial pressure of oxygen-permeable membrane, relying on oxygen partial pressure gradient through the membrane into the electrode. The applied voltage of 0.4V ~ 0.8V range of oxygen partial pressure in the platinum cathode surface was restored electrolyte analyzer electrode current increased with the increase of applied voltage.
When the oxygen concentration diffusion gradient is relatively stable, it creates a stable electrolysis current, called the limiting diffusion current. Limiting diffusion current size is determined by how many of the penetration to the cathode surface oxygen, which in turn depends on the oxygen partial pressure in the outer membrane. Therefore, the partial pressure of oxygen in the blood samples can be determined by determination of the current changes.
Electrolyte analyzer, when the applied voltage exceeds 0.8V, even if the oxygen partial pressure = 0 mmHg, water itself would be electrolysis to generate electricity. Therefore, the operating voltage plus the partial pressure of oxygen electrode is typically 0.65V.
These are the two working electrode blood electrolyte analyzer principle, the reference only to learn!
