Description

Technical Field

[0001] The utility model relates to medical instruments and medical auxiliary equipment, in particular to a pulse-type flushing tube structure. Background Art

[0002] Indwelling intravenous catheters have been widely used in clinical practice. They can reduce the pain of repeated punctures for patients and the workload of nursing staff. Flushing is one of the important links to ensure the normal use of indwelling intravenous catheters.

[0003] The purpose of flushing is to flush the residual drug solution in the catheter into the blood vessel and clear the accumulated drug solution in the catheter, thereby reducing the risk of incompatible drugs coming into contact with each other and preventing the occurrence of complications.

[0004] At present, the flushing method is generally for medical personnel to hold a syringe to flush the catheter, using a push-and-stop flushing method to make the saline form a small vortex in the catheter to flush out the residual drug in the intravenous catheter.

[0005] At present, the flushing method is used. The flushing effect is determined by the professional level of the operator and cannot be guaranteed.

[0006] Therefore, it is necessary to provide a pulse flushing structure to solve the above problems. Utility Model Content

[0007] The utility model aims to provide a pulse type pipe flushing structure.

[0008] The utility model achieves the above-mentioned purpose through the following technical solutions:

[0009] A pulse flushing tube structure, comprising a syringe corresponding card for clamping the upper end of the barrel of an injection syringe, and a simulated pulse propulsion module for propelling a syringe injection push rod is provided on the corresponding syringe corresponding card;

[0010] The simulated pulse propulsion module includes a propulsion drive member formed by a DC motor, and the propulsion drive member is connected to a propulsion corresponding module;

[0011] The DC motor performs several continuous thrusts, each with an interval of A. Each thrust injects N volume of solution in the injection syringe into the intravenous indwelling catheter, forming a simulated pulse-feeding flushing structure.

[0012] Furthermore, the propulsion corresponding module includes a screw, a screw nut is arranged on the screw, and a propulsion head used in conjunction with the syringe injection push rod is connected to the screw nut.

[0013] Furthermore, the pulse-feed flushing tube structure was simulated to perform 10 continuous push injections, each with an interval of 0.4 s and 1 ml of solution each time.

[0014] Furthermore, the syringe corresponding card includes a main card body, and a group of auxiliary cards are correspondingly arranged on the main card body.

[0015] Furthermore, a group of auxiliary card bodies can be slidably connected to the main card body through the sliding grooves, and through a corresponding group of corresponding card slots, a highly universal injection syringe clamping part that can adapt to injection syringes of various specifications can be slidably formed.

[0016] Furthermore, the simulated pulse propulsion module also includes a control panel.

[0017] Furthermore, the control panel includes a display screen and at least includes a push count setting button, an interval time setting button, a feed amount setting button for each push, and a reset button.

[0018] Compared with the prior art, the utility model performs flushing of the intravenous indwelling catheter by simulating a pulse feeding type flushing structure, thereby ensuring the flushing effect. BRIEF DESCRIPTION OF THE DRAWINGS
