technical field

The utility model belongs to the field of medical instruments, in particular to a color difference detection device capable of identifying blood components.

Background technique

At present, human blood donation is still the main source of medical blood. When donating blood, often only one or several specific blood components are needed, such as plasma, platelets, red blood cells, etc., while other components can be transfused back to the blood donor to avoid waste of blood resources and reduce adverse reactions of blood transfusion. Therefore, in modern blood donation technology, the method of centrifugal separation and collection of blood components is often used, that is, the whole blood collected by the blood donor is centrifuged into different components, the required components are taken out, and the remaining components are returned to the blood. to blood donors.

Existing blood component collection machines (such as NGL XCF-3000 blood component separator) pipeline detectors are currently based on the theory of luminous flux division to detect the blood components that need to be taken out. The concentration of each blood component is different, and there is still a certain error in accurately detecting the components in the pipeline only by the change of the luminous flux.

Therefore, it would be very meaningful to develop a device that can determine the composition of blood without being affected by individual factors.

It should be understood that the specific embodiments described here are only used to explain the utility model, and are not intended to limit the utility model.

As shown in Figure 1-2, it is an embodiment of a color difference detection device capable of identifying blood components of the present invention. The present invention includes a pipe clip 10, and the pipe clip 10 holds a polymer pipeline 9 inside. The exterior of the polymer pipeline 9 is provided with a first-stage optical dust-proof lens 4, and on one side of the first-stage optical dust-proof lens 4, a triangular prism sheet 3 and a white light emitting tube 2 are sequentially arranged on one side of the first-stage optical dust-proof lens 4. The white light emitting tube 2 is connected to the emission cable 1, and on the other side of the first-stage optical dust-proof lens 4, a second-stage optical dust-proof lens 5, a color code spectrum sensor 6, a white Screen signal trigger 7, the white screen signal trigger 7 is connected to the receiving cable 8, the pipe clamp 10 is made of aluminum alloy material, and the inner and outer surfaces are processed by a blackened surface treatment process, such setting can Prevent the impact of external light on the detection of the device, thereby improving the accuracy of its detection. The white light emitting tube 2 is a high-frequency composite white light source emitting tube with a power of 150-200mw and a frequency of 1000Hz-5500Hz. The light intensity is over 14000mcd, the luminous flux accuracy is over 3.5lm, and the color temperature is 5600-9000K. Such a setting makes it free from any risk factors of damage to the blood components, and can meet the requirement that it can penetrate the components to be detected, so as to realize the detection function. The color standard spectrum sensor 6 should have a sensing accuracy of the wavelength of light within ± Within 2.5%, the sensitivity of the white screen signal trigger 6 should have a high response speed, and the response time should be in the range of 0.1-1ms.

Its working principle is: as shown in Figure 2, the function of the utility model is completed on an aluminum alloy frame called pipe clamp 10, and all functional parts are completed in the pipe clamp, when the multi-color white light is emitted by white light The tube 2 decomposes and emits different monochromatic light after being refracted by the triangular prism sheet 3 , passes through the first-stage optical dust-proof lens 4 , and irradiates the polymer pipeline 9 . When the components of different colors flow through the polymer pipeline 9, only the light of the corresponding color can be transmitted, and all the light of other colors will be received. The transmitted light passes through the second-level optical dust-proof lens 5 and irradiates on the color code spectrum sensor 6, and the color code spectrum sensor will sense the wavelength of the received light to cut off the color of the component. The light after spectrum detection will form a bright spot on the color mark corresponding to the color mark, and trigger the signal corresponding to the white screen signal trigger 7, and transmit the signal to the signal processing system of the host through the receiving cable 8 for different components. Collection process, when the polymer pipeline 9 was an empty tube, what was full of in the pipeline was sterile air. The transparent tube and the air pass through all the white light, and then the color code spectrum sensor 6 and the white screen signal trigger 7 sense and trigger the wavelength λ to be within the entire compound light range of 380-780 nm. At this time, the spectral detection and color mark sensing will give this signal, and the signal processing system of the host computer will collect these signals as the basic signal. It can be determined that the medium is air, and when the transparent plasma passes through the polymer pipeline 9, the plasma itself is pale yellow. The transmitted light wave passes through the color code spectrum sensor 6 and the white screen signal trigger 7, and triggers the wavelength λ to be within the range of 570-600 nm of monochromatic yellow light. It can be judged as yellow light. It is finally determined that the component in the polymer pipeline 9 is plasma, and when the mixed cells of opaque platelets and a small amount of plasma pass through the polymer pipeline 9 (the actual centrifugation process is without pure platelets), the color is yellowish brown. It will reflect light at wavelengths between the yellow and green spectrums. Other monochromatic light will pass through the components, then through the color code spectrum sensor 6 and the white screen signal trigger 7, the wavelength λ is sensed and triggered, and the whole composite light range is 380-780 nm, and within the range of 570-630 nm, a section will be disconnected. The received spectrum will be in two segments. The processing system of the signal processing system of the host computer finds that the missing spectral range is yellowish brown when the basic signal changes, and finally determines that the component in the pipeline polymer pipeline 9 is platelets. When granulocytes such as opaque white blood cells pass through the polymer pipeline 9, it appears white. Complex white light will be fully reflected. Then the wavelength λ triggered by the color code spectrum sensor 6 and the white screen signal trigger 7 should be 0. In fact, the high-frequency light will have a very weak wavelength, which must be lower than 380nm. The processing system of the signal processing system of the main engine finds that the missing spectral range is white when the basic signal changes, and finally determines that the components in the polymer pipeline 9 are white blood cells. When the polymer pipeline 9 passes through the opaque red blood cells , in red. The transmitted light wave is sensed and triggered by the color code spectrum sensor 6 and the white screen signal trigger 7 to the range of 380-630 nm of monochromatic yellow light with a wavelength λ, just missing the light wave of red light 630-780 nm, and the signal processing system of the host computer processes The system finds that when the basic signal changes, it can be judged as red light, and finally determines that the components in the pipeline polymer pipeline 9 are red blood cells.
