Abstract
The utility model discloses a set of equipment of radioactivity medical appliance, specifically(discloses) a blood irradiator which can regulate the center dosage rate. Through the combine(combination) of the up and down movement of the radioactive source and the rotation movement of the irradiative vessel, the utility model can make the irradiative vessel rotate while the radioactive vibrate up and down regularly, therefore, the evenness of the irradiation of the irradiative vessel is improved; through the adjustment of the position of the shield, the distance between the center of the irradiator vessel and the center of the radioactive source, and the thickness of the shielding level between the center of the irradiator vessel and the center of the radioactive source is changed to realize the aim of regulating the center dosage rate of the irradiative vessel of the same specification.
Description
Technical field
This utility model belongs to a kind of radiating medical apparatus, is specifically related to a kind of blood irradiation machine.
Background technology
Blood transfusion is an important means of medical treatment, but the incidence rate that GVHD (TA-GVHD) takes place in the blood transfusion process according to statistics can reach about 15～20%, and mortality rate reaches more than 90%.It is one of the severe complications of transfusing blood.Phase in August, 1996 in Yale's medical college and Kang Laike university medical college " medical science " magazine claims: studies show that TA-GVHD is contained in the whole blood cell, defeated with whole blood, erythrocyte, platelet, fresh plasma and from normally donate blood people and chronic leukemia people from cell the time, all can cause this class syndrome.Medical research confirms: blood product wherein has immunocompetent lymphocyte to lose vigor behind the gamma-ray irradiation of suitable dosage, even thereby import in the hypoimmunity patient body, can not produce attacking ability to body yet.And gamma-rays to Fei Linba be cell (as erythrocyte, platelet etc.) without any side effect, this has guaranteed patient's transfusion safety when having significantly reduced that immunodeficiency patient accepts blood products and the incidence rate of GVHD takes place, and has strengthened the treatment of blood transfusion effect.
The mid-80, American-European developed country progressively adopts special-purpose blood irradiation machine to carry out, but its irradiation uniformity can only reach ± and 20%, the center close rate of same size irradiation vessel can not be regulated, and can not be used for experiment with fields such as blood specimen and zoopery, biomaterial, the researchs of electronic devices and components irradiation.
Summary of the invention
The purpose of this utility model provides and a kind ofly can improve the irradiation uniformity, can realize the blood irradiation machine that same size irradiation vessel center close rate is adjusted again.
This utility model is achieved in that a kind of blood irradiation machine of adjusting the center close rate, it comprises fixed shield, be positioned at the shielding drum of fixed shield one side and be positioned at the fixed shield gamma-rays radiation source assemblies moving up and down of opposite side admittedly, be provided with irradiation vessel at the shielding drum, wherein, shielding drum lower end is equipped with gyroaxis, this gyroaxis is connected with shielding drum rotational motion mechanism, the bottom of said irradiation vessel is provided with turning cylinder, and the gyroaxis that this turning cylinder passes shielding drum bottom links to each other with the irradiation vessel rotational motion mechanism.
The utility model has the advantages that: rotatablely moving with irradiation vessel by radioactive source is moved up and down combines, and makes irradiation vessel in rotation, and radioactive source is made clocklike the irradiation uniformity that concussion motion has up and down improved irradiation vessel; By shielding the adjustment of bulging position, change the distance at irradiation vessel center and radioactive source center, change the shielding thickness between irradiation vessel and the radioactive source simultaneously, realize the purpose of the center dosage rate of adjustment same size irradiation vessel.
Description of drawings
Fig. 1 is a structure diagram of the present utility model;
Fig. 2 is an A-A cutaway view among Fig. 1.
Among the figure, 1 shielding drum, 2 irradiation vessels, 3 shielding drum rotational motion mechanisms, 4 irradiation vessel rotational motion mechanisms, 5 radiation source assemblies motions, 6 gamma-ray radiation source assemblies, 7 fixed shields.
The specific embodiment
As shown in Figure 1, a kind of blood irradiation machine of adjusting the center close rate, it comprises fixed shield 7, be positioned at the shielding drum 1 of fixed shield 7 one sides and be positioned at the fixed shield 7 gamma-rays radiation source assemblies 6 moving up and down of opposite sides admittedly, be provided with irradiation vessel 2 at shielding drum 1, it is characterized in that: shielding drum 1 lower end is equipped with gyroaxis, this gyroaxis is connected with shielding drum rotational motion mechanism 3, the bottom of said irradiation vessel 2 is provided with turning cylinder, and the gyroaxis that this turning cylinder passes shielding drum 1 bottom links to each other with irradiation vessel rotational motion mechanism 4.
Gamma-rays radiation source assemblies 6 in this utility model can be done concussion motion up and down by radiation source assemblies motion 5, and can in the process of motion, different dwell point and residence time and movement velocity be set, this radiation source assemblies motion 5 is a known technology; Irradiation vessel 2 can be rotated motion around the axis of self, and can adjust the movement velocity of container around self axis rotation according to the size of irradiation vessel, and these two kinds motions are coupling mutually, can improve the irradiation uniformity of irradiator.
This utility model can be used for the irradiation of blood and blood product, and some experiment is with the irradiation research of blood specimen and zoopery, biomaterial, electronic devices and components etc.
