Abstract
The utility model relates to a blood irradiator with cobalt-60 radioactive sources, which belongs to medical equipment and is used for inactivating lymphocytes with immunocompetence in blood. The blood irradiator is characterized in that the irradiator comprises a supporting main body and a supporting frame, wherein a circular depressed cavity corresponding to a rotary worktable is formed on the supporting main body; a material pick-and-place cavity is formed on the rotary worktable; the supporting main body and the inner cavity of the rotary worktable are filled with shielding materials; the top part of the rotary worktable is connected with a worm and gear transmission pair; a rotary material carrying base plate is arranged at the bottom of the material pick-and-place cavity; an irradiation door is arranged corresponding to the rotary worktable; and a cobalt-60 radioactive source drawer for placing the cobalt-60 radioactive sources is arranged corresponding to the interior of the rotary worktable. By using the cobalt-60 radioactive sources, the blood irradiator has the advantages of safety, reliability, low price and use cost, no radioactive source vibration, simple structure and reliable performance.
Description
Technical field
This utility model relates to a kind of cobalt-60 radioactive source for blood irradiator, belongs to medical facility, is used for deactivation blood and has immunocompetent lymphocyte.
Background technology
The radiation treatment technology of blood (or blood products) is widely used after the seventies, especially to the patient of bone marrow transplant patient, leukemia people and other immunologic hypofunction.At present, the used radioactive source of most of blood irradiator is caesium-137, but the half-life of cesium-137 radioactive source is longer, there is certain potential safety hazard, simultaneously because the domestic cesium-137 radioactive source commercial product that does not still have high activity, therefore the center close rate of cesium-137 radioactive source for blood irradiator is on the low side, costs an arm and a leg, and use cost is than higher.
The utility model content
The purpose of this utility model is to provide a kind of cobalt-60 radioactive source for blood irradiator, and safe and reliable, price is low, and use cost is low.
Cobalt described in the utility model-60 radioactive source for blood irradiator, comprise support body and bearing support, support body is provided with the circular depressed cavity that adapts with rotary table, rotary table is provided with material and picks and places cavity, be filled with shielding material in support body and the rotary table inner chamber, the top of rotary table is connected with the worm and gear transmission, the bottom that material picks and places cavity is provided with rotation loading chassis, the corresponding irradiation door that is provided with rotary table is with the inboard corresponding radioactive source drawer that is provided with storing cobalt-60 radioactive source of rotary table.
Wherein, rotation loading chassis can drive in several ways, as being fixed on the gear wheel, be connected on the power transmission shaft with the pinion of gear wheel engagement, the lower end of power transmission shaft connects driving device, and power transmission shaft carries out transmission by pinion and gear wheel, drives rotation loading chassis and rotates; Also can directly be fixed on rotation loading chassis in the rotating shaft; Or the like.
The work engineering:
Open the irradiation door, the container that the irradiation thing is housed is placed on the rotation loading chassis, close the irradiation door, rotate rotary table and go to the irradiation position, the irradiation thing is carried out irradiation, rotate the loading chassis simultaneously and drive the rotation of irradiation thing.The start-stop position of rotary table can be finished by the programme-control of independent setting, and irradiation finishes, and rotary table is got back to start bit automatically, opens the irradiation door, takes out the irradiation thing.
This utility model cobalt-60 radioactive source for blood irradiator uses cobalt-60 radioactive source, and safe and reliable, price is low, and use cost is low, and need not radioactive source vibration, designs simplification, dependable performance.

Fig. 1, this utility model one example structure sketch map.
A-A cross section structure sketch map among Fig. 2, Fig. 1.
Rotation loading chassis rotational structure sketch map among Fig. 3, Fig. 1.
Among the figure: 1, fast 4, the support body 5 of irradiation container 2, worm and gear transmission 3, the protection of radioactive source location, shielding material 6, radioactive source drawer appliance 7, rotary table 8, rotation loading chassis driving device 9, rotation loading chassis 10, irradiation door 11, gear wheel 12, pinion 13, power transmission shaft.
The specific embodiment
The utility model is described in further detail in conjunction with the foregoing description accompanying drawing.
As Fig. 1, shown in Figure 2, cobalt described in the utility model-60 radioactive source for blood irradiator, comprise support body 4 and bearing support, support body 4 is provided with the circular depressed cavity that adapts with rotary table 7, rotary table 7 is provided with material and picks and places cavity, be filled with shielding material 5 in the inner chamber of support body 4 and rotary table 7, the top of rotary table 7 is connected with worm and gear transmission 2, the bottom that material picks and places cavity is provided with rotation loading chassis 9, with the rotary table 7 corresponding irradiation doors 10 that are provided with, the inboard corresponding radioactive source drawer appliance 6 that is provided with storing cobalt-60 radioactive source with rotary table 7, can adorn 1 radioactive source in the radioactive source drawer, also can adorn 2 radioactive sources.
As shown in Figure 3, rotation loading chassis 9 is fixed on the gear wheel 11, and the pinion 12 that meshes with gear wheel 11 is connected on the power transmission shaft 13, and the lower end of power transmission shaft 13 connects rotation loading chassis driving devices 8 such as motor.
The work engineering:
