Novel multifunctional urinary catheter

Abstract

The invention provides a novel multifunctional urinary catheter. The urinary catheter mainly comprises a urine catheter, a fixed balloon catheter and a thickened balloon catheter, wherein the urine catheter, the fixed balloon catheter and the thickened balloon catheter are arranged in parallel from above a joint part; a urine inlet is formed in the side wall of a urethral insertion end of the urine catheter, a urine outlet is formed in the in-vitro end of the urine catheter, and a water stop clip is arranged on the urine catheter between the joint part and the urine outlet; the joint part of the urine catheter is provided with an injection catheter communicated with the urine catheter, a rubber sealing flap 2 is arranged at the tail end of the injection catheter, and the urine catheter andthe injection catheter are provided with guide wires through self-closing holes. The multifunctional urinary catheter has the advantages that urine cannot flow out of the urinary catheter during theinsertion operation, urine cannot flow out of the urinary catheter during the use process, sterile operation and use can be realized, bladder administration or bladder irrigation can be facilitated, the inflation condition of balloons can be observed, the infection risk of patients can be better reduced, and the health of patients can be protected.

Description

technical field [0001] The invention relates to a urinary catheter used in the medical field, in particular to a novel multifunctional urinary catheter. Background technique [0002] Urinary catheterization refers to the method of inserting a urinary catheter through the urethra into the bladder to drain urine under strict aseptic operation. Draining urine for patients with urinary retention through a catheter can not only relieve the pain of the patient, but also help clinical diagnosis, such as taking uncontaminated urine samples for bacterial culture, measuring bladder capacity and pressure, etc. [0003] However, if the aseptic operation is not strictly implemented during the catheterization operation, iatrogenic infection may easily occur, and the medical staff must strictly abide by the aseptic operation principle when catheterizing the patient. However, in the insertion operation of the catheters currently on the market, when connecting the syringe and pulling out th...

AI Technical Summary

Problems solved by technology

[0003] However, if the aseptic operation is not strictly implemented during the catheterization operation, it may easily lead to iatrogenic infection, and the medical staff must strictly abide by the principle of aseptic operation when catheterizing the patient.

However, in the insertion operation of the catheters currently on the market, when connecting the syringe and pulling out the guide wire, the water-stop clamp needs to be opened. During this process, the catheter is in an open state, and urine will flow out from the bladder to pollute the surrounding environment (such as bed or other medical equipment)

During the use of the urinary catheter, urine often flows out of the catheter because the catheter is too thin, or even the fixed air bag of the catheter is ruptured and leaks, causing the catheter to fall off from the patient's urethra, resulting in urinary Accidental outflow of fluid increases the risk of infection and endangers the health of patients

At the same time, during the insertion of the catheter, if the patient's urethra is too dry and the catheter is difficult to insert, it is impossible to further input lubricating fluid to facilitate the insertion of the catheter, and there are also problems such as the external end of the catheter is too slippery and the operation is inconvenient.
