Prostate urethra medicine-infusion washing drainage tube

Abstract

The invention is the prostate urethra medicine injection and washing drainage tube, which comprises a tube body, two tube cavities of the prostate urethra part medicine injection and washing drainage tube cavity and a bulboperineal urethra balloon tube cavity are arranged in the tube body; the front part of the tube body is provided with a bulboperineal urethra balloon wrapped around the tube body, the opening on the front end of the bulboperineal urethra balloon tube cavity is communicated with the bulboperineal urethra balloon, and the opening on the tail end thereof is arranged on the tail end of the tube body and is communicated with the outside of the tube body, the tube port of the opening on the tail end is provided with a one-way rubber plug; the opening on the front end of the prostate urethra part medicine injection and washing drainage tube cavity is arranged before the bulboperineal urethra balloon near the tube body wall on the front end of the tube body and is communicated with the outside of the tube body, the opening on the tail end thereof is arranged on the tail end of the tube body and is communicated with the outside of the tube body, the tube port of the opening on the tail end is provided with a one-way rubber plug; the opening on the front end of the prostate urethra part medicine injection and washing drainage tube cavity is 1.0cm-3.0cm far away from the opening on the front end of the bulboperineal urethra balloon tube cavity. The invention cancels the vesical cervix balloon tube cavity and the vesical cervix balloon in the catheter of the prior art, which reduces the diameter of the catheter, relieves the pain of the patient, and the sealing function is better. The invention saves materials, simplifies production art, and reduces production cost, thus the treatment charge is largely reduced for patients. Therefore, the invention is more favorable for clinic promotion compared with the prior art.

Description

technical field [0001] The invention relates to a drainage catheter for the human body, in particular to a prostatic urethral drug injection flushing drainage catheter. Background technique [0002] An existing urinary catheter only includes two lumens and an air bag, i.e. bladder neck air bag, bladder neck air bag lumen, and catheter lumen. When using this urinary catheter, insert the urinary catheter into the human bladder, align the bladder neck airbag of the catheter with the bladder neck opening of the human body, The air bag is inflated, so that the bladder neck air bag closes the bladder neck opening, the head opening of the catheter lumen is placed in the bladder, and urine is discharged through the catheter lumen. The function of the urinary catheter bladder neck airbag is to block the neck of the bladder, preventing the blood and pus in the prostatic fossa from entering the bladder to form a clot to block the urinary catheter, and the function of the urinary cathe...

AI Technical Summary

Problems solved by technology

Although this drainage catheter provides a new method of local irrigation and drainage for the treatment of prostatitis, and uses the bladder neck airbag to seal the bladder neck, so that the perfused medicinal solution is not easy to flow back to the bladder, it is found in clinical practice that it is used to prevent The sealing effect of the bladder neck airbag where the medicinal liquid enters the bladder is not ideal, which affects the local perfusion pressure and irrigation and drainage of the prostatic urethra.

This is because after the perfusion and drainage operation begins, the medicine liquid will impact the front bladder neck airbag along the catheter with the help of pressure and make it swing left and right. The left and right swing of the bladder neck airbag will give the bladder neck an opening force, which reduces This reduces the local perfusion pressure in the prostatic urethra, and at the same time prevents the bladder neck sphincter from contracting and closing effectively; Easily reaches the bladder neck and enters the bladder along the smooth bladder neck bladder wall; therefore, the bladder neck bladder has limited sealing effect on the prostatic segment of the urethra

In addition, because the catheter includes three lumens and two balloons, compared with a catheter that only includes two lumens and one balloon, the diameter of the catheter is increased, material is wasted, the production process becomes complicated, and the production cost is lower. Increased, also increased the patient's pain when using

In addition, because different people have different lengths of the prostate segment of the urethra, and the distance between the two balloons on the catheter is fixed, it is impossible to design a drainage tube for each person. In this way, the fixed distance between the two balloons is also It will affect the sealing effect of the two balloons on the prostatic urethra
