 Blood Irradiation Indicator Stickers

A blood irradiation instruction sticker, the utility model relates to a blood irradiation instruction sticker, belongs to the biomedical and radiation technology combination of a medical device.
Irradiation technology in the field of biomedical applications is very extensive, mainly blood irradiation. Blood irradiation refers to the whole blood or component of blood to a certain dose of radiation treatment, radiation mainly refers to Y-ray. Blood irradiation is currently the only method used to prevent blood transfusion-related graft-versus-host disease. Although the current blood irradiator can be free to adjust the dose, but the actual absorption of blood Y-ray dose is not necessarily the national standard dose (usually 25Gy). Now the blood station and the hospital radiation workers in the blood only after the use of a pen to record the amount of radiation dose used, and can not really determine the actual absorption of blood radiation dose. Although there are Y-ray dosimeter, but because of its more expensive, the use of inconvenient, blood stations and hospital staff are not used. At present, there are some radioactive labeling labels, but because of the need for advanced scanner with the software to analyze the radiation dose, but also because of its expensive and inconvenient to use and rarely used in clinical. To overcome the above shortcomings, to provide a low cost, simple production, easy to use, small size, carrying, and can be intuitive to judge the new blood irradiation instructions stickers. In order to achieve the above object, the utility model includes an indicator card and a sticker, and the indicating card is a circular colored small piece having a diameter of 8-12 mm and a thickness of 0.5-1.0 mm.
 
 

    

OBJECTIVE: To prepare a radiation discoloration that identifies the dose of blood radiation, and to understand the correspondence between the absorbance peak and the inhibition rate of lymphocyte response. Methods The radiation discs and blood were prepared by irradiation with 5, 15, 25, 35 and 50Gy radiation doses respectively. The absorbance and the inhibition rate of lymphocyte reaction were measured before and after irradiation. The results showed that the radiation coloring film had low dose response, and the color of the film changed from pink to blue after irradiation with the blood. The absorbance of the absorption peak was correlated with the inhibition rate of blood lymphocyte reaction. Conclusion It is possible to determine whether the blood bag is irradiated by the naked eye and determine the absorbance of the radiation discoloration to quantitatively identify the radiation dose of the blood. The radiation discoloration has important application prospect in the prevention of TA-GVHD by blood irradiation.
