Infusion pump of electric control liquid stop clip

Abstract

The invention discloses an infusion pump of an electric control liquid stop clip. The infusion pump of the electric control liquid stop clip comprises a middle plate, a switch arranged on the middle plate, a control module, a motor, a transmission device and the liquid stop clip for clamping an infusion tube, wherein the control module is electrically connected between the switch and the motor and is used for controlling the motor to act; a check block is fixedly arranged on the middle plate; the liquid stop clip is arranged on the middle plate in a sliding mode and opposite to the check block; the transmission device comprises a transmission shaft and a linkage assembly; the transmission shaft is connected with the motor in a transmission mode; and the linkage assembly is connected between the transmission shaft and the liquid stop clip. The automatic opening and closing of the liquid stop clip can be achieved only by triggering the switch and using the control module to control the motor to act, labor is greatly saved, besides, operation is very convenient, and work efficiency is obviously improved. By using matching of the motor and the transmission device, big clamping force can be provided to enable an infusion tube to firmly clamp; and meanwhile, acting force of the liquid stop clip to a pump door can be eliminated, and closing and opening the pump door is convenient.

Description

technical field [0001] The invention belongs to the field of medical equipment, and in particular relates to an infusion pump for electrically controlling a stop clip. Background technique [0002] The liquid stop clamp is a device on the medical infusion pump, which is used to clamp the infusion tube to block the pipeline when the pump door of the infusion pump is open, that is, when the infusion line is not blocked by the peristaltic pump. When the infusion pump works, the closed pump door always presses the liquid stop clip to keep it in an open state, and the liquid stop clip always has a greater thrust on the pump door under the action of the spring. The traditional liquid stop clips are all manually controlled, relying on the force provided by the spring to make the liquid stop clip clamp the infusion tube, because the infusion tube needs to be effectively blocked, so the driving spring force of the liquid stop clip is generally relatively large. Therefore, when remov...

AI Technical Summary

Problems solved by technology

Therefore, when removing or installing the infusion tube, the human hand needs to overcome the relatively large resistance of the spring and press the liquid stop clamp, and one hand must always press the stop liquid clamp during the process of removing or installing the infusion tube, and the other hand must press the liquid stop clip. It is very laborious and inconvenient to remove or install the infusion tube by hand; because a large force needs to be applied to the infusion pump, it is easy to cause the infusion pump to fall and cause danger

After closing the pump door, rely on the pump door to press down the liquid stop clip to open it, so the liquid stop clip will also have a large force against the pump door when the infusion pump is working, causing inconvenience to the opening and closing of the pump door
