Abstract
The utility model belongs to medical equipment field and especially relates to a fluid irradiator. The fluid irradiator includes a protector equipped with a radioactive source. The radioactive source is installed in a radioactive source shell. A through chamber is arranged in the radioactive source shell. A channel for fluid flowing is arranged corresponding to the through chamber. An inlet and an outlet of the channel are both arranged outside the protector. The fluid irradiator in the utility model has advantages of simple and compact structure, small volume, high efficiency and uniform irradiation. The protector is formed by clamping two hemispheres mutually, thereby facilitating dismounting and installation. The radioactive source shell is disposed in the center of the protector. The channel is in an S shape, thereby not only guaranteeing the flowing of the fluid, but also preventing the external environment from irradiation.
Description
Technical field
This utility model relates to a kind of fluid irradiation instrument, belongs 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 appearance generally includes parts such as outer housing, turntable, turntable driving, rotation driving, source vibration component and control chamber; Complex structure; Volume is big, when irradiation, because blood is in a fixed container, causes phenomenons such as irradiation is inhomogeneous easily.
The utility model content
The technical problem that this utility model will solve is: a kind of fluid irradiation instrument simple and compact for structure, efficient, uniform is provided.
This utility model is that the technical scheme that its technical problem of solution is adopted is: said fluid irradiation instrument; It is characterized in that: comprise protection body; Radioactive source is arranged in the protection body, and radioactive source is installed in the radioactive source housing, and 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, avoids 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; 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.
Said protection body comprises the two halves spheroid, and the two halves spheroid combines through the draw-in groove 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.
Said 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 through 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 through unsteady flow amount control detection device and flow detector realization convection cell realize that through the radiation sensitive analytical instrument quality of convection cell irradiation is controlled.
The beneficial effect of this utility model 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 the structural representation of this utility model;
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 accompanying drawing this utility model is done and to be further described:
Like Fig. 1～shown in Figure 3, the described fluid irradiation instrument of this utility model comprises 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 combines through the draw-in groove on the faying face 6.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, through 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 through the outlet of pipeline 4, flow to the fluid dispenser case through flow detector and radiation sensitive analytical instrument then.
