Assembly device of liquid check clips and catheters

Abstract

The invention discloses an assembly device of liquid check clips and catheters, and belongs to the technical field of manufacturing equipment of medical instruments. According to assembly devices of the liquid check clips and the catheters in the prior art, the ends of the catheters are worn in the assembly process, the structures of the assembly devices are complex, and the control difficulty is increased. The assembly device comprises a machine frame, a feed mechanism, a taking mechanism, a guide rod mechanism penetrating through the liquid check clips and a pushing mechanism. The taking mechanism comprises a taking and horizontal-moving assembly driving the liquid check clips to horizontally move, a taking and vertically-moving assembly driving the liquid check clips to vertically move, a clamping plate clamping the liquid check clips and a clamping drive assembly driving the clamping plate to do reciprocating motion. The pushing mechanism comprises expanding plates used for driving the liquid check clips to horizontally move and opening-closing drive sources used for driving the expanding plates to do reciprocating motion, and the opening-closing drive sources drive the expanding plates to be inserted into gaps of the liquid check clips. The assembly device is convenient to assembly, simple in structure and reasonable in design and can effectively improve the assembly efficiency.

Description

technical field [0001] The invention relates to a liquid stop clip and a catheter assembly device, which belongs to the technical field of medical equipment manufacturing equipment. Background technique [0002] The liquid stop clip is an essential part of the infusion set. In order to reduce bacterial infection and speed up the assembly efficiency, mechanical equipment is generally used to automatically assemble the liquid stop clip and the infusion catheter. Chinese patent (patent number: 2013107553260) proposes a medical catheter and The assembly device of the liquid stop clip, in which the calibration platform adopts the vibration transmission method, and by setting a number of corresponding calibration points, the liquid stop clips are gradually realized in the same direction and arranged in an orderly manner. The calibration table sets the calibration point to adjust the orientation of the liquid stop clip while delivering the liquid stop clip, and then transmits the l...

AI Technical Summary

Problems solved by technology

The patented calibration station sets calibration points to adjust the direction of the liquid stop clip while delivering the liquid stop clip, and adjusts the direction of the liquid stop clip in the chute, which may easily cause the liquid stop clip to get stuck in the chute and block the chute

At the same time, it is used to transport the liquid stop clips arranged on the calibration table to the transfer clip at the needle bar, but there is no technical solution for realizing the function of the transfer clip, and no such solution is disclosed in the prior art

In the above-mentioned patent, the push rod is pierced with the needle bar, and the push rod pushes the liquid-stopping clip also pierced with the needle bar to assemble with the catheter. Since the function of the liquid-stopping clip is to clamp the catheter, the opening for the catheter to pass through is made smaller than the diameter of the catheter , the push rod directly pushes the liquid stop clamp to penetrate the conduit, which may lead to unsuccessful assembly. Even if the liquid stop clip penetrates the conduit, the end of the conduit will be worn, which will have a bad impact on the quality of the product; the above patent only When the liquid clamp is assembled with the catheter: a large thrust will be generated on the catheter. In order to prevent the catheter from moving, it is necessary to set the positioning clip of the pipe body to keep the position of the catheter during assembly. Although this can increase the success rate of assembly, it will make the entire assembly device Complicated, increasing the difficulty of control
