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
In human body platelet or fresh blood, be all mixed with lymphocyte, in the time that the blood that contains a large amount of immunocompetent lymphocyteses of this allosome or blood constituent are input in immunocompromised patient body, just can cause " transfusion-associated graft versus host disease " generation (TA-GVHD), the caused death that degree is serious.Adopt lonizing radiation blood or blood product is carried out to irradiation effectively in deactivation blood, to have immunocompetent T lymphocyte, infusion can effectively prevent the generation of TA-GVHD through the blood of lonizing radiation irradiation or blood constituent, make to transfuse blood safer.
Traditional blood irradiator generally includes the parts such as outer housing, turntable, turntable driving, rotation driving, source vibration component and control chamber, complex structure, volume is large, in the time of irradiation, because blood is in a fixing container, easily causes the phenomenons such as irradiation is inhomogeneous.
Summary of the invention
The technical problem to be solved in the present invention is: a kind of simple and compact for structure, efficient, uniform fluid irradiation instrument is provided.
The present invention for the technical scheme that its technical problem of solution adopts is: described fluid irradiation instrument, comprise protection body, in protection body, there is radioactive source, radioactive source is arranged in radioactive source housing, radioactive source housing is provided with and runs through cavity, correspondence runs through cavity and is provided with the mobile pipeline of fluid, and the import of pipeline and outlet are all 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, in protection body, have radioactive source, in radioactive source housing, be provided with and run through cavity, the mobile pipeline of fluid this cavity of flowing through, through radioactive source radiation, irradiation is even and efficiency is high, and the import of pipeline and outlet are all arranged on the outside of protection body, can connect respectively fluid service tank and fluid dispenser case, use and put just.
Described protection body comprises two halves spheroid, and two halves spheroid is by the draw-in groove combination on faying face.Protection body is two hemispheres body structure, facilitates 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 S shape pipeline.Radioactive source housing is arranged on the center of protection body, can save space, and can reduce the amount of radiation of radioactive source to external environment, and pipeline is 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, for different field.
Fluid irradiation instrument can connect Pneumatic Pressure service tank by pipeline one end, the other end connects fluid dispenser case, variable-flow control checkout gear is installed on the pipeline between fluid irradiation instrument and Pneumatic Pressure service tank, flow detector and radiation sensitive analytical instrument are installed on the pipeline between fluid irradiation instrument and fluid dispenser case, realize flow detection and the control of convection cell by variable-flow control checkout gear and flow detector, realize the quality of convection cell irradiation by radiation sensitive analytical instrument and control.
Advantage of the present invention is:
Simple and compact for structure, volume is little, efficient and irradiation is even; Protection body is that the engaging of two halves spheroid forms, for convenience detach and installation; Radioactive source housing is arranged on the center of protection body, and path is S shape path, has both ensured flowing of fluid, has played again the effect that prevents radiation external environment.
Brief description of the drawings
Fig. 1 is structural representation of the present invention;
Fig. 2 is the top view of Fig. 1;
Fig. 3 is A-A cross section structure schematic diagram in Fig. 1.
In figure: 1, support 2, protection body 3, radioactive source 4, pipeline 5, radioactive source housing 6, draw-in groove.
Detailed description of the invention
Below in conjunction with drawings and Examples, the present invention is described further.
Embodiment 1:
As shown in FIG. 1 to 3, fluid irradiation instrument of the present invention, comprise support 1, protection body 2 is installed on support 1, in protection body 2, have radioactive source 3, radioactive source 3 is arranged in radioactive source housing 5, and radioactive source housing 5 is provided with and runs through cavity, correspondence runs through cavity and is provided with the mobile pipeline of fluid 4, and the import of pipeline 4 and outlet are all arranged on the outside of protection body 2.Protection body 2 comprises two halves spheroid, and two halves spheroid is by draw-in groove 6 combinations on faying face.Radioactive source housing 5 is arranged on the center of protection body 2, and pipeline 4 is S shape pipeline.
When use, selective emission source irradiation dose, fluid flows out from Pneumatic Pressure service tank, by variable-flow control checkout gear, flow in protection body 2 through the import of pipeline 4, through radioactive source 3 irradiation, flow out protection body 2 by the outlet of pipeline 4, then flow to fluid dispenser case by flow detector and radiation sensitive analytical instrument.
