Contact-limited type double saccule double-cavity catheter

Abstract

The invention relates to a contact-limited type double saccule double-cavity catheter and belongs to the technical field of auxiliary medical instruments. The contact-limited type double saccule double-cavity catheter is characterized in that a catheter body is made of polymer blend, the outer lateral walls of two saccules of the catheter get thinner gradually from the tip ends to the tail ends, and the two saccules are symmetrically arranged on two sides of the catheter body between the tip ends and the a cavity hole of a drain pipe. The using method of the catheter is that: users can fill water or air when urine exists. The catheter is arranged in the two saccules behind the bladder and inclines toward the tail end in water filling or air filling state, a framework space formed by the saccules and the bottom of a bladder wall is enough to contain a trigone of the bladder, the catheter can be continuously fixed in the bladder without pressing the trigone of the bladder and a ureteral orifice, a drainage hole of a drain pipe cavity is adjacent to the ureteral orifice, urine can be evacuated timely and thoroughly, and the tip ends of the catheter, the two saccules, water or air filling pipe cavities communicated with the saccules, the drainage hole of the drain pipe cavity, the drain pipe cavity, a back flow resisting valve and a conical connector of the drain cavity are integrated through a pipe body.

Description

Technical field [0001] The invention relates to a restricted contact type double-balloon two-lumen urinary catheter, which belongs to the technical field of medical auxiliary equipment. Background technique [0002] In the medical field, it is necessary to insert a urinary catheter and indwelling catheterization for internal diseases, surgical diseases, obstetrics and gynecology diseases, orthopedics diseases and urology diseases. The urinary catheter is a commonly used medical auxiliary device, which can be inserted into the bladder through the diseased urethra to guide the flow of urine. After the urinary catheter is inserted into the bladder, there is a balloon near the head end of the urinary catheter, which is used to fix the catheter in the bladder and prevent it from coming out. The drainage part of the urinary catheter is connected to the urine bag to collect urine. Common problems of indwelling urinary catheter include urinary tract infection, poor drainage, difficult e...

AI Technical Summary

Problems solved by technology

[0003] There is a distance of 3-5cm between the drainage hole of the two-chamber urinary catheter of the existing balloon and the bottom of the bladder, and there is a balloon in between, and some urine remains in the bottom of the bladder all the time; the urine in the bladder is generally sterile, However, urine is also a suitable environment for bacteria, and it is easy to breed bacteria; when the urine cannot be completely emptied, the urine remains at the bottom of the bladder, allowing bacteria to form, and it is prone to inflammation; Contact with residual urine will easily deposit calculus salt at the end of the urinary catheter to form stones; the balloon will be round after being filled with water or inflated, and the wall of the airbag will continue to stimulate and rub against the trigone of the bladder, causing inflammation, and the patient will experience frequent urination, urgency, and lower abdomen Distension and discomfort; urinary leakage caused by urethral relaxation; elderly women, intracranial lesions, and paraplegic patients with pelvic floor muscles and urethral sphincter relaxation, resulting in urinary leakage; in addition, long-term indwelling catheters make the bladder empty for a long time, and the bladder detrusor Disuse atrophy, leading to bladder contracture; the traditional method of using a urinary catheter requires about 3 cm of insertion after seeing urine before injecting water or air
