Irradiation indicating card and methods for preparing and using the same

Abstract

The invention discloses an irradiation indicating card and methods for preparing and using the same. The irradiation indicating card comprises a standard color code and an indicating card; the standard color code is an annular card and is divided into six equal parts that are six areas with different colors; each area represents a corresponded irradiation dose; and the six kinds of colors of the six areas respectively represent the following irradiation doses: 50 G y, 30 G y, 25 G y, 15 G y, 5 G y and 1 G y from deep to shallow; a center of the annulus is an empty hole and is used for placing a colorimetric area of the indicating card; and a diameter of the empty hole is 7 to 11 mms; besides, right and back sides of the standard color code are processed by film pressing processing. Moreover, the indicating card is a rectangular card with a length of 40 to 60 mms, a height of 12 to 22 mms and a thickness of 0.5 to 1.0 mms. According to the invention, the above-mentioned structure is employed; the irradiation indicating card has lightweight and is easy to be taken by hands to carry out color comparison; furthermore, the preparation and the usage methods are simple; it is easy to determine irradiation doses; and the detection result is accurate; besides, the irradiation indicating card can be cleaned and disinfected as well as be used repeatedly for many times.

Description

technical field [0001] The invention relates to an irradiation indication card, which belongs to a medical device combining biomedicine and radiation technology. Background technique [0002] Irradiation technology is widely used in the field of biomedicine, mainly including blood irradiation. Blood irradiation refers to a certain dose of radiation treatment on whole blood or blood components. Radiation mainly refers to gamma rays. Blood irradiation is currently the only method used to prevent transfusion-associated graft-versus-host disease. Although the current blood irradiator can adjust the dose at will, the actual gamma-ray dose absorbed by the blood is not necessarily the national standard dose (generally 25Gy). At present, the staff of blood banks and hospitals who irradiate the blood just use a pen to record the radiation dose used, but cannot really determine the actual radiation dose absorbed by the blood. Although there are gamma ray dosimeters now, they are not...

AI Technical Summary

Problems solved by technology

Now the blood bank and hospital irradiation staff just record the irradiation dose with a pen after the blood is irradiated, but cannot really determine the actual irradiation dose absorbed by the blood

Although there are gamma-ray dosimeters now, they are not used by staff in blood stations and hospitals because of their high price and inconvenient use.

At present, there are also some domestic literatures reporting radiation indicator labels, but they are rarely used clinically because they require advanced scanners and software to analyze the radiation dose, and because they are expensive and inconvenient to use.
