Balloon catheter for entering pelvic cavity by guiding and use method

Abstract

The invention discloses a balloon catheter for entering pelvic cavity by guiding and use method, and relates to the technical field of medicine instruments. The balloon catheter comprises a balloon, acatheter body and a plug, the shape of the catheter body seems a common guide wire, the catheter body is provided with a hollow inner cavity, a closed balloon end and an opened water injection end are arranged at two ends of the hollow inner cavity of the catheter body, the balloon is connected on the outer surface of the balloon end, a plurality of micro-holes are formed in the balloon end and communicated with the hollow inner cavity and the hollow inner cavity of the catheter body, the plug is positioned at the water injection end and plugged into an opening of the water injection end, andthe balloon is made of an inflated or contracted soft elastic material. The balloon catheter can help a doctor to lead a peritoneum dialysis catheter into low position of the pelvic cavity and can also help the doctor to lead the peritoneum dialysis catheter floated to an abdominal cavity into the low position of the pelvic cavity again, so that the catheter is safely and reliably placed by a blind penetrating method, and the balloon catheter has a wide clinical application prospect.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a balloon catheter leading into the pelvic cavity and a usage method. Background technique [0002] Peritoneal dialysis is an important renal replacement modality for end-stage renal disease. There are three methods of maintenance peritoneal dialysis catheterization: direct vision surgical incision catheterization, peritoneoscopic catheterization and blind perforation catheterization. At present, most of the major peritoneal dialysis centers in my country adopt open-sight surgical incision method to insert catheters. [0003] 1. Direct vision surgical incision method: It is the most commonly used peritoneal dialysis catheterization at present. Its advantages are: it is operated under local anesthesia and direct vision, the anatomical structure is clear, and the risk of injury and bleeding is small. It can communicate and cooperate closely, and the dialysis catheter ...

AI Technical Summary

Problems solved by technology

[0003] 1. Direct vision surgical incision method: It is the most commonly used peritoneal dialysis catheterization at present. Its advantages are: it is operated under local anesthesia and direct vision, the anatomical structure is clear, and the risk of injury and bleeding is small. It can communicate and cooperate closely, and the dialysis catheter can be placed in place; the disadvantage is that the trauma is relatively large, and some patients may have incisional hernia or fluid leakage in the early use

[0004] 2. Laparoscopic tube placement: At present, it is rarely used clinically. Its advantages are: with the help of laparoscope, the whole operation is visualized, more intuitive and accurate, with less trauma and faster postoperative recovery. It is more suitable for peritoneal dialysis tube reset and stripping The greater omentum and patients with abdominal complications expand the indications for peritoneal dialysis patients; the disadvantages are: surgical equipment is expensive, surgical personnel need special training, and the operation is general anesthesia, CO 2 Artificial pneumoperitoneum has potential toxicity to the kidneys. At the same time, in the state of continuous pneumoperitoneum, the renal arteries may contract, the renal blood flow may decrease, and the production of metabolites such as urea nitrogen and creatinine may increase.

[0005] 3. Blind puncture catheterization: generally used for the placement of acute peritoneal dialysis catheters, the operation is simple and fast, and has the natural advantages of being fast, economical and easy to promote, especially for children and elderly patients with acute kidney injury and other diseases that cannot be achieved by other methods. However, due to the blind insertion, the blind insertion method has a greater risk of injuring abdominal organs, and the position of the catheter is not easy to control. It mainly has the following disadvantages:

This method may also cause damage, and the probability of tube drift is high; it is not simple and easy to solve the problem of tube drift in existing peritoneal dialysis tubes

[0008] (3) In some patients who have undergone peritoneal dialysis, the peritoneal dialysis tube of some patients will drift from the pelvic cavity to the abdominal cavity, and symptoms such as reduced ascites drainage, poor drainage, tube blockage, omentum wrapping, etc. often need laparoscopy Solve, or even terminate peritoneal dialysis, there is no simple and easy solution
