Problems solved by technology

[0007] However, at present, the ultraviolet light source of the blood inactivation equipment using the photochemical method is single, and the ordinary fluorescent ultraviolet lamp is used. The ultraviolet intensity emitted by the light source is small, and it cannot emit high-intensity ultraviolet light, resulting in a long blood processing time. less processing
In addition, the size and length specifications of ordinary ultraviolet lamps are relatively single, and the utilization rate is low, which cannot meet the customization requirements of large-scale or miniaturized blood inactivation equipment

Embodiment 1

[0063] Embodiment 1 Static blood inactivation treatment

[0064] The present invention provides an application of an LED ultraviolet light source in a photochemical blood inactivation treatment device. The structure of the outer case 1 of the device is shown in FIG. 1 . The front structure of the outer chassis 1 is as follows: Figure 1a As shown, the outer case 1 is a cuboid, the length of the outer case is 1268 mm, the width is 635 mm, and the height is 1660 mm. The front of the outer case 1 is provided with a control panel 2 and a sample port 3 . The sample port 3 is rectangular, the length of the sample port 3 is 300mm, and the width is 70mm. The sample port 3 is arranged in an array on the front of the outer chassis 1, and is arranged in 2 rows, 4 in each row. A movable plate 301 is provided on the surface of the sample port 3. The size of the movable plate 301 is the same as that of the sample port 3. The lower end of the movable plate 301 is hinged on the front of the ...

Embodiment 2

[0073] Embodiment 2 Fluid dynamic blood inactivation treatment

[0074] When using bagged blood containers 14 for blood flow inactivation treatment, open the cabinet door 6 of the outer cabinet 1, and insert the hard plate 145 of the connecting part of each bagged blood container 14 into the blood container slots on both sides of the sample expansion tray 801 In 806, the bagged blood container 14 is fixed; the blood inlet pipe 142 of each bagged blood container 14 is communicated with the blood outflow pipe 143 of the previous bagged blood container 14 by using a flexible tube, and the blood outlet pipe 143 of the first bagged blood container 14 The flexible pipe connected to the blood inlet pipe 142 stretches out from the flowing blood inlet 101 on the side of the outer case 1, and connects the power delivery device and the blood source. The flowing blood outlet 102 extends out to connect a blood source or other container.

Abstract

The invention discloses application of an LED ultraviolet lamp source in photochemical blood inactivation treatment equipment. The LED ultraviolet lamp source can be applied to a methylene blue / visible light treatment method, a psoralen / UVA treatment method and a riboflavin / UV treatment method. The invention also provides full-automatic blood inactivation treatment equipment with the LED ultraviolet light source. The full-automatic blood inactivation treatment equipment with the LED ultraviolet light source comprises an outer case, a sample rack, a blood container and an LED ultraviolet lamp plate, wherein a control panel and a sample port are arranged on the front surface of the outer case; the sample rack is provided with a plurality of sample telescopic plates, and the sample telescopicplates can stretch out or draw back to the sample port; and the blood container is bag-shaped or tubular, and the blood in the container is static or dynamic. According to the equipment provided by the invention, a full-automatic control system is adopted, ultraviolet emission intensity of the LED ultraviolet lamp can be actively adjusted, the irradiation intensity can be increased, so that the treatment time is greatly shortened, the treatment efficiency is improved, and large-scale or miniaturized treatment can be realized.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to the application of an LED ultraviolet light source in photochemical blood inactivation treatment equipment. Background technique [0002] With the continuous development of medical technology, blood transfusion therapy has become a common medical method in modern medicine, for example, surgery requires a large number of blood transfusion operations. However, blood is a good culture medium for bacteria and viruses, especially various viral hepatitis, AIDS and other viruses, which widely exist in blood. If not handled properly, blood will become a medium for spreading diseases. Therefore, diseases transmitted through the use of blood products are even more worrying. [0003] The main method to ensure the safety of blood products is the inactivation of pathogens. The inactivation of blood pathogens refers to the destruction of the structure of viral proteins or viral nucleic acids...
