Real-time sampling device for detecting pressure of blood culture bottle

Abstract

The invention discloses a real-time sampling device for detecting pressure of a blood culture bottle. The real-time sampling device comprises a sampling assembly and a pressure detection assembly, wherein the sampling assembly is arranged at a bottleneck of the blood culture bottle; the sampling assembly and the pressure detection assembly are integrally arranged; the sampling assembly comprises a sampling needle which extends into the blood culture bottle; the tail end of the sampling needle is connected with a sampling extrusion rod; a sterile needle sleeve for the sampling needle sleeves the head end of the sampling needle; the pressure detection assembly comprises a pressure detection needle which extends into the blood culture bottle; a sterile needle sleeve for the pressure detection needle sleeves the head end of the pressure detection needle; and a sensing opening at the tail end is connected with the pressure sensing detector. The real-time sampling device has the advantages that the defects that unattended operation and real-time inspection cannot be realized by an existing instrument, and the culture time cannot be strictly controlled are solved by the design; unmanned automatic operation is realized in the whole process; manpower and material resources are saved; the instantaneity and the accuracy of inspection data are also ensured; the improvement cost is low; and the real-time sampling device is suitable for kinds of medical treatment and scientific research institutions.

Description

technical field [0001] The invention relates to a detection and sampling device for blood culture of clinical blood samples, in particular to a real-time sampling device for pressure detection of blood culture bottles. Background technique [0002] At present, except for a very small number of hospitals that have purchased semi-automatic and fully automatic blood culture instruments, most hospitals, especially grassroots hospitals, still use old and backward triangular flasks to make blood culture media for bacterial culture. It is large and has a wide exposure area, and external bacteria can easily enter the culture medium to cause contamination, and also increase the risk of cross-infection by inspectors; however, semi-automatic and fully automatic blood culture instruments are still inseparable from inspectors on duty. Timing operation cannot realize unattended, real-time inspection and other requirements, especially the cultivation time cannot be strictly controlled. C...
