WIPO Patent Application WO/2023/046186
Kind Code:
A1
Abstract:
The present invention provides a sampling needle cleaning device and a sampling needle cleaning system applying said device, the sampling needle cleaning device comprising a body, and a cleaning channel that contains a sampling needle is penetratingly provided in the axial direction of the body; when the sampling needle is cleaned in the cleaning channel, the sampling needle is in clearance fit with the cleaning channel; the body comprises a connecting body and cover bodies that cover two ends of the connecting body; concave parts are provided at the two ends of the connecting body, and protruding parts are provided on the cover bodies; the protruding parts extend into the concave parts to cooperate with the concave parts to form cavities; the cavities are arranged around the circumference of the cleaning channel, and the arrangement range of the cavities around the circumference of the cleaning channel is smaller than one circle; and the connecting body is further provided with a liquid inlet and a liquid outlet, the liquid inlet and the liquid outlet being in communication with a corresponding cavity, respectively; and the cavities communicate with the cleaning channel, and the liquid inlet and the liquid outlet have a height difference in the gravity direction. According to the present solution, the flow channel structure in the sampling needle cleaning device may be effectively simplified, thereby avoiding that pollution is carried into the flow channel and affecting the cleaning of the sampling needle.
