Description

Sterile blood sampling facility based on organ transplantation early detection
Technical Field
The invention relates to the technical field of medical instruments, in particular to a sterile blood sampling facility based on organ transplantation early detection.
Background
Organ transplantation is the process of surgically transferring an organ, either wholly or partially, from one individual to another. The aim is to replace a damaged or dysfunctional organ with a good organ from a donor. The organ donor may be a donor for organ transplantation, and may be a human or a human who has just died. The recipient of the organ is the recipient of the organ transplant.
Before organ transplantation, the donor is subjected to blood collection and blood culture evaluation to evaluate whether the donor is suitable for donation, at the moment, aseptic blood collection protective measures need to be taken, if the donor has infectious bacteria, the donor organ is transplanted to a receptor of the organ transplantation, and after the receptor receives the transplantation, under the conditions of poor original physical condition and immunosuppressive treatment, the receptor faces postoperative infection, treatment difficulty and slow recovery.
The current blood culture device is not different from a common blood sampling device, and has no protection of an outer sleeve and the possibility of pollution. If cross contamination is caused artificially in the blood sampling process, the donor is misjudged, the donor is considered to have infectious bacteria, and the donor is abandoned, so that the waste of rare donor resources is caused, and the source of the life-saving donor is reduced.
Therefore, in view of the above, the present invention provides an aseptic blood collection facility based on organ transplantation early detection by improving the existing structure and defects, so as to achieve the purpose of higher practical value.
