Leakage plugging detector for infusion sets

Abstract

The invention discloses a leakage plugging detection apparatus for infusion sets, comprising a worktable arranged on a fixing frame. A medicine over-compression device for fixing a liquid medicine filter, an infusion set pressure detector, an exhaust pipe fixture and a controller are arranged on the worktable. The infusion set pressure detector comprises an air supply pipe and a pressure sensor, one end of the air supply pipe is hermetically connected with a conical head of the liquid medicine filter, the other end thereof is communicated with an air source through a guide pipe and an electromagnetic valve, and the pressure sensor is disposed on the air supply pipe. The pressure sensor, the electromagnetic valve and the exhaust pipe fixture are all electrically connected with the controller. A foot switch electrically connected with the controller is disposed on the fixing frame. The leakage plugging detection apparatus has the advantages such that infusion set leakage plugging detection is more precise, detection precision is reliable, detection is efficient, operating is simple and quick, and manpower cost is greatly lowered.

Description

technical field [0001] The invention relates to a detection device of a medical device, in particular to a detection machine for leakage and blockage of an infusion set. Background technique [0002] The infusion set is a commonly used medical device, its schematic diagram is shown in figure 1 , the infusion set includes a liquid medicine filter 11 arranged at one end of the infusion set and a puncturer 12 at the other end, an exhaust pipe 13 extends from one side of the puncturer 12, and an exhaust pipe 13 is arranged at the top of the exhaust pipe. The gas membrane 14 and the airtightness of the infusion set need to be tested during production. Damage, double membrane, lack of membrane, etc. [0003] Existing detection of leakage and blockage of infusion sets is manual detection. The detection process is: first clamp the exhaust pipe 13, then connect the cone 15 of the liquid medicine filter 11 with a tee, and the other end of the tee is connected to the air source. Con...

Problems solved by technology

The detection is carried out by manually observing the changes of the pressure gauge. On the one hand, the accuracy of the pressure gauge is low, which limits the accuracy of leak detection and plugging. False detection rate and missed detection rate affect the efficiency of detection
