Female needle base breakover test device

Abstract

The invention discloses a female needle base breakover test device and belongs to the field of medical mechanical equipment. A female needle base cannot be detected safely and effectively via technologies of the prior art, a conventional positioning device is normally used for conveying the female needle base and a catheter which is connected with the female needle base to a V-shaped groove and positioning the female needle base and the catheter; the female needle base can move easily under action of external force and therefore assembling failure can be caused. The female needle base breakover test device comprises a positioning mechanism used for positioning the catheter and the female needle base and a detection mechanism used for detecting whether the female needle base is in a breakover state; the positioning mechanism comprises a catheter clamping mechanism used for positioning the catheter and a clamping mechanism used for positioning the female needle base. The clamping mechanism is positioned between the catheter clamping mechanism and the detection mechanism. The catheter and the female needle base can be separately clamped via the positioning mechanism, the female needle base can be effectively fixed, convenience of detection can be realized for the detection mechanism, and detection safety and accuracy can be improved.

Description

technical field [0001] The invention relates to a female needle-based measuring conduction device, which belongs to the field of medical machinery and equipment. Background technique [0002] The female needle base is a part of the infusion set. The infusion set is widely used in the field of medical infusion. The infusion set generally includes catheters, filters, pump adapters, puncture needles, liquid stop clips, female needle bases, etc. In order to ensure the efficiency of processing and assembly and avoid bacterial contamination, the assembly and testing of various parts of the infusion set need to be completed by automated equipment. The female needle base is generally glued to the catheter. If too much glue is applied to the connection, it may cause blockage of the connection between the two. If too little glue is applied, it may cause air leakage at the connection between the two. [0003] Chinese patent (patent number: 201210284180.1) discloses an air leakage dete...

Problems solved by technology

But it doesn't give the fixing device when the female needle base and catheter are tested

The positioning device in the prior art generally transports the catheter to the V-shaped groove for positioning. Because the female needle base is heavy, the catheter of the infusion set is relatively soft and generally relatively long, resulting in the port of the female needle base cannot be kept flush

And the catheter is not firmly fixed in the V-shaped groove. When there is an external force, the catheter is also easy to move, which cannot meet the positioning requirements of the female needle base test.

And when the air pressure is detected, the female needle base needs to withstand a large air pressure. If the female needle base is not firmly positioned, it is easy to fly out and cause a safety accident

In order to meet the positioning needs, some factories use manipulators to grab catheters for positioning, but the structure of the manipulator equipment is complex and the control programming is cumbersome
