AI Technical Summary

Technical Problem

The design of existing catheters leads to bladder and urinary tract irritation, inability to discharge urethral mucosal secretions, forming biofilms, increasing the risk of CAUTI, and difficulty in inserting the catheter in patients with urethral stenosis.

Method used

A catheter device is designed, including a catheter and a positioning structure. The positioning structure elastically deforms to pass through the urethra when under stress, and is positioned at the mouth of the bladder neck after recovery, and by forming a spacer on the outer wall of the catheter and setting a sealing ring and through hole on the catheter, stimulation of the urethral mucosa and accumulation of secretions are reduced.

Benefits of technology

It reduces the stimulation of the catheter device to the bladder wall, reduces the risk of infection, and improves the flexibility and success rate of catheter placement.

Abstract

The present application provides a urinary catheter device, which mainly includes a catheter with a main lumen and a positioning structure connected to the main lumen. The catheter can be inserted into the urethra, and the positioning structure can extend axially from the distal end of the catheter and expand radially outward, wherein the positioning structure can elastically deform under stress to enter the bladder through the urethra, and can elastically recover under no stress to be positioned at the bladder neck. Thus, the present application can improve the positioning effect of the urinary catheter device in the urethra, and can conveniently perform the insertion and removal operations of the urinary catheter device.
