Balloon-free indwelling catheter

Abstract

The invention discloses a balloon-free indwelling catheter. The technical scheme of the invention has the key points that the balloon-free indwelling catheter comprises a catheter body; a drainage cavity duct is formed in the catheter body; the drainage cavity duct comprises a drainage inlet formed in the front end of the catheter body; limiting flaps used for limiting slippage of the catheter body are arranged at the front end of the catheter body; one side of each limiting flap is connected with the front end of the catheter body, and the other side of the limiting flap can be always kept in an outward opening state in a natural state; at least two limiting flaps are arranged and are arranged around a drainage inlet; the outer diameter of each limiting flap in the opening state is larger than that of the catheter body; the catheter body is provided with a traction rope capable of pulling the limiting flaps to be gradually bent until the limiting flaps are folded; the catheter body is provided with a traction cavity duct for the traction rope to penetrate through; and the outer diameter of each limiting flap in the folded state is not larger than that of the catheter body. Related risks of a balloon in the indwelling period can be effectively avoided.

Description

technical field [0001] The invention relates to a urinary catheter, more specifically, it relates to a balloon-free indwelling urinary catheter. Background technique [0002] In the current medical and health work, it is very common for patients to insert an indwelling catheter due to the needs of diagnosis and treatment of the disease. However, after the catheter is inserted, it is generally necessary to inject water into the balloon at the end of the catheter to fix it. In most cases, indwelling balloon catheters can meet clinical needs, but in many cases, existing indwelling balloon catheters have many defects related to related complications during use and cannot fully meet actual clinical needs. Balloon catheters have many unavoidable risks, such as rupture of the balloon, blockage of the inflation cavity of the balloon, leakage of water from the balloon and the inflation path, and incomplete recovery of the deformation of the balloon after indwelling. Moreover, once t...

AI Technical Summary

Problems solved by technology

Leakage of the balloon or inflation path can also lead to water leakage from the balloon and failure of indwelling catheterization, bringing risks such as repeated intubation, infection and trauma to the patient

However, when the permanent deformation of the balloon cannot be restored due to long-term water injection, if no external force is applied to pump water, the balloon may be larger than the inner diameter of the urethra. It will lead to difficult extubation, damage to the urethra, etc.

The above-mentioned deficiencies are especially when the internal urethra is unclear, such as when the patient is more sensitive to balloon stimulation, and the judgment of the length of the patient's urethra is inaccurate, etc.
