Description
Technical Field
The invention relates to the technical field of glass blood collection tube production, in particular to a gamma-ray irradiation resistant glass blood collection tube and a preparation method thereof.
Background
The collection of blood specimens is the most common and very important work in the collection of hospital test specimens, and disposable vacuum blood collection tubes are widely used. With the continuous development of medical inspection technology, the quality requirement on a blood sample before analysis is higher and higher, and the quality of a vacuum blood collection tube has a remarkable influence on the quality of the sample. According to the CFDA examination and guidance principle of the registration technology of disposable vacuum blood collection tubes, it is known that if the products are not sterilized or are not sterilized completely, the liquid in the blood collection tube can mildew and cause product pollution, and if blood backflow occurs in the use process of the disposable vacuum blood collection tubes, septicemia can be caused to patients, so that the disposable vacuum blood collection tubes need to be sterilized. The traditional medical blood collection tube is sterilized by a high-pressure steam cooking method before use, and has low efficiency and poor effect. In recent years, the method of adopting gamma ray irradiation for disinfection and sterilization is rapidly popularized, and the method is simple and reliable, has high efficiency and good effect. However, the glass blood collection tube produced in China at present is easy to discolor after being irradiated by gamma rays, and the use effect of the blood collection tube is seriously influenced
