Non-bag leakage-proof indwelling catheter as well as manufacturing method and application thereof

Abstract

The invention relates to a non-bag leakage-proof indwelling catheter and a manufacturing method and application thereof. The non-bag leakage-proof indwelling catheter comprises a catheter body, a drainage channel, a supporting device, a fixing device, a releasing device and a bending adjusting device, and the catheter body is provided with a leakage-proof hole; the catheter body and the supporting device are wrapped by the release device before the non-capsular indwelling catheter is placed into the human body, and after the non-capsular indwelling catheter is placed into the human body, the release device is opened, and the supporting device naturally opens in the bladder; after the supporting device is opened, the fixing device is opened, fixation is formed, and the urethral tube is prevented from falling off; the bending adjusting device can adjust the front end of the catheter to bend, and use is convenient; according to the non-bag leakage-proof indwelling catheter, residual urine in the bladder can be completely discharged, the urine leakage phenomenon is effectively avoided, urinary tract inflammation and infection caused by the residual urine are reduced, and the user experience is improved.

Description

technical field [0001] The invention belongs to the medical field, and relates to catheterization supplies for patients, in particular to an indwelling urinary catheter without a capsule and an anti-leakage, as well as its manufacturing method and application. Background technique [0002] Urinary catheterization is one of the basic nursing operations. It refers to the method of inserting a catheter through the urethra into the bladder to extract urine under strict aseptic conditions. It is often used clinically to relieve urinary retention, measure residual urine, and collect bladder urine Examination, avoiding incontinence in anesthetized patients, promoting postoperative recovery of patients with urinary system diseases, etc.; urinary catheter is a key surgical instrument for establishing a urine drainage channel in catheterization, and is a necessary medical instrument in clinical operations and nursing processes. [0003] At present, 99.9% of indwelling catheters used c...

AI Technical Summary

Problems solved by technology

[0003] At present, 99.9% of indwelling catheters used clinically belong to Foley catheters, which are equipped with an inflatable balloon at the front end of the catheter. When the front end of the catheter is inserted into the patient's bladder, the balloon is inflated with water. , the balloon can be stuck on the neck of the bladder to fix the catheter and prevent the catheter from falling off; however, the Foley balloon catheter has the following risks and defects: (1) The balloon is perforated or even ruptured, causing the The causes of balloon perforation or rupture are mainly product quality defects and the use of inappropriate lubricants. Such adverse events account for more than 26% of catheter adverse events. Once the balloon ruptures, not only the indwelling catheter fails, It will also cause balloon fragments to be left in the patient's bladder, requiring surgical removal, which will increase the patient's pain; It is complicated, but the root cause is the design defect of the Foley balloon catheter; in order to inflate the balloon smoothly, the catheter hole is set at the front of the balloon, which makes it impossible to drain the bladder during the catheterization process Under the comprehensive influence of various external factors and the patient's own reasons, it will eventually lead to urine leakage; (3) It is difficult to pull out the catheter, and the indwelling catheter will remain in the patient's body for several days or even Tens of days, long-term inflation of the balloon will lead to deformation and poor retraction. When extubating, if no external force is applied to pump out the water in the balloon, a small amount of water will remain in the balloon. If external force is applied to pump out the water in the balloon , the balloon will fold due to deformation, which will make it difficult to pull out the catheter anyway and damage the urethra; (4) The balloon is squeezed into the urethra and causes damage. The balloon is still soft and deformable after being filled with water, and it will be stuck under normal conditions Prevent the catheter from falling off at the neck of the bladder, but the patient may accidentally pull the catheter when changing the body position or performing other actions. Under this instantaneous and strong pull, the balloon will be deformed and squeezed into the urethra, resulting in Injury; (5) Bring continuous urge to urinate to the patient. The position of the balloon in the bladder is in the trigone of the bladder, which is the baroreceptor of the bladder. The compression of the balloon here will bring continuous urge to urinate to the patient , causing discomfort to the patient
