Abstract
The invention, which belongs to the medical equipment field, especially relates to a fluid irradiation instrument. The instrument comprises a protective body; there is a radioactive source in the protective body and the radioactive source is installed in a housing of the radioactive source; and a penetrating cavity is arranged on the housing of the radioactive source and a pipeline is arranged correspondingly to the penetrating cavity and is used for flowing of fluid; besides, an inlet and an outlet of the pipeline are arranged at outboard of the protective body. According to the invention, advantages of the instrument are as follows: the structure is simple and compact; the volume of the instrument is small; and the efficiency is high and irradiation is uniform; besides, the protective body is formed by two hemispheres in a clamping mode, so that the instrument can be disassembled and installed conveniently; moreover, the housing of the radioactive source is arranged in the center of the protective body and a pathway is in an S shape, so that flowing of the fluid can be ensured and radiation on external environment can be prevented.
Description
Technical field
The present invention relates to a kind of fluid irradiation instrument, belong to field of medical.
Background technology
All be mixed with lymphocyte in human body platelet or the fresh blood, when the blood that contains a large amount of immunocompetent lymphocyteses of this allosome or blood constituent are input in the immunocompromised patient body, just can cause " blood transfusion dependency graft versus host disease " generation (TA-GVHD), the caused death that degree is serious.Adopt lonizing radiation that blood or blood product is carried out irradiation and effectively have immunocompetent T lymphocyte in the deactivation blood, infusion is through the generation that the blood or the blood constituent of lonizing radiation irradiation can effectively prevent TA-GVHD, make transfuse blood safer.
Traditional blood irradiation instrument generally includes parts such as outer housing, turntable, turntable driving, rotation driving, source vibration component and control chamber, complex structure, volume is big, because blood is in a fixed container, causes phenomenons such as irradiation is inhomogeneous easily when irradiation.
Summary of the invention
The technical problem to be solved in the present invention is: a kind of fluid irradiation instrument simple and compact for structure, efficient, uniform is provided.
The technical scheme that the present invention is adopted for its technical problem of solution is: described fluid irradiation instrument, comprise protection body, radioactive source is arranged in the protection body, radioactive source is installed in the radioactive source housing, the radioactive source housing is provided with and runs through cavity, correspondence runs through the pipeline that cavity is provided with fluid flow, and the import of pipeline and outlet all are arranged on the outside of protection body.
Adopt the fluid irradiation instrument of this structure, simple and compact for structure, protection body can prevent radioactive source radiation external environment, avoid causing environmental pollution, human body is damaged, radioactive source is arranged in the protection body, be provided with in the radioactive source housing and run through cavity, the pipeline of fluid flow this cavity of flowing through, through radioactive source radiation, irradiation is even and efficient is high, and the import of pipeline and outlet all are arranged on the outside of protection body, can connect fluid service tank and fluid dispenser case respectively, use and put just.
Described protection body comprises the two halves spheroid, and the two halves spheroid is by the draw-in groove combination on the faying face.Protection body is the two hemispheres body structure, makes things convenient for the installation and removal of radioactive source housing and pipeline.
Described radioactive source housing is arranged on the center of protection body, and pipeline is a S shape pipeline.The radioactive source housing is arranged on the center of protection body, can save the space, and can reduce the amount of radiation of radioactive source to external environment, and pipeline is a S shape pipeline, also can increase shield effectiveness, reduces the amount of radiation to external environment.
This fluid irradiation instrument not only can radiation blood, also can utilize the various fluids of different radioactive source radiations, is used for different field.
The fluid irradiation instrument can connect pneumatic forced feed case by pipeline one end, the other end connects the fluid dispenser case, unsteady flow amount control detection device is installed on the pipeline between fluid irradiation instrument and the pneumatic forced feed case, flow detector and radiation sensitive analytical instrument are installed on the pipeline between fluid irradiation instrument and the fluid dispenser case, flow detection and control by unsteady flow amount control detection device and flow detector realization convection cell realize that by the radiation sensitive analytical instrument quality of convection cell irradiation is controlled.
Advantage of the present invention is:
Simple and compact for structure, volume is little, and is efficient and irradiation is even; Protection body forms for the engaging of two halves spheroid, for convenience detach and installation; The radioactive source housing is arranged on the center of protection body, and path is a S shape path, has both guaranteed fluidic flowing, and has played the effect that prevents the radiation external environment again.
Description of drawings
Fig. 1 is a structural representation of the present invention;
Fig. 2 is the vertical view of Fig. 1;
Fig. 3 is an A-A cross section structure sketch map among Fig. 1.
Among the figure: 1, support 2, protection body 3, radioactive source 4, pipeline 5, radioactive source housing 6, draw-in groove.
The specific embodiment
Below in conjunction with drawings and Examples the present invention is described further.
Embodiment 1:
As Fig. 1～shown in Figure 3, fluid irradiation instrument of the present invention, comprise support 1, protection body 2 is installed on the support 1, radioactive source 3 is arranged in the protection body 2, and radioactive source 3 is installed in the radioactive source housing 5, and radioactive source housing 5 is provided with and runs through cavity, correspondence runs through the pipeline 4 that cavity is provided with fluid flow, and the import of pipeline 4 and outlet all are arranged on the outside of protection body 2.Protection body 2 comprises the two halves spheroid, and the two halves spheroid is by 6 combinations of the draw-in groove on the faying face.Radioactive source housing 5 is arranged on the center of protection body 2, and pipeline 4 is a S shape pipeline.
During use, selective emission source irradiation dose, fluid flows out from pneumatic forced feed case, by unsteady flow amount control detection device, import through pipeline 4 flows in the protection body 2, through radioactive source 3 irradiation, flow out protection body 2 by the outlet of pipeline 4, flow to the fluid dispenser case by flow detector and radiation sensitive analytical instrument then.
