CVC indwelling catheter water flow detection device

Abstract

The invention relates to a CVC indwelling catheter water flow detection device which comprises a base bracket, wherein the base bracket is fixedly connected with a base frame, the top part of the base frame is provided with a water outlet tank, the water outlet tank is connected with a water outlet pipe, the water outlet pipe is provided with an electromagnetic valve, the water outlet pipe is connected with a conversion pipe, the base frame is provided with a measuring cup, the electromagnetic valve is provided with a control circuit, the control circuit comprises a control module and a timing module, the timing module comprises a timer connected to the electromagnetic valve, when the electromagnetic valve is opened, the timer starts timing, when the timing time reaches a preset time value, the timing module transmits a water flow control signal to the control module, the control module is connected with the timing module and responds to the water flow control signal output by the timing module, and after the control module receives the water flow control signal, the control module controls the electromagnetic valve to be powered off and stop working. According to the CVC indwelling catheter water flow detection device, the work of testing the water flow of a CVC pipe can be normally and efficiently carried out, so that the workload of a user is reduced, and the working efficiency is improved.

Description

technical field [0001] The present application relates to the field of detection devices, in particular to a detection device for water flow in a CVC pipe. Background technique [0002] A CVC catheter, also known as a central venous catheter, is a type of endovascular catheter. The CVC catheter is made of silicone and PU materials. CVC catheters can be used to measure central venous pressure, to assess circulatory physiological parameters, to provide large and rapid intravenous infusions, and to serve as conduits for hemodialysis. [0003] At present, there is a water flow detection device. Connect the CVC tube to the adapter, turn on the switch, and start manual timing at the same time. The water in the water tank flows into the CVC tube through the water pipe and the adapter, and the water flows out through the CVC tube. The measuring cup collects the water flowing out of the CVC tube. After 60 seconds of manual timing, check the water volume in the measuring cup, and th...
