Minimally invasive subpressure bladder puncture and fistulation remaining device and working method thereof

Abstract

The invention relates to a minimal invasive negative pressure bladder puncture fistulation indwelling device and the working method, which pertains to the technical field of medical devices, including a fistulation tube, a fixed board, a negative pressure urine drainage bag and a puncture needle, the fistulation tube is a tube which is provided with an opening at one end and is smoothly closed and bent at the other end, a plurality of side holes are arranged on the inner side wall of the bending part, a spring device is arranged in the negative pressure urine drainage bag, a connection soft tube is arranged at the inlet at the upper end, the end part of the connection soft tube is provided with a connector part, the lower end thereof is provided with an outlet soft tube, switches are arranged on the connection soft tube and the outlet soft tube, the fixed main board body is a broken annular board, the inner side of the annular shape is provided with a serrated protuberance, the broken part of the fixed board is provided with a slidable tooth buckle, and the periphery of the main body board is provided with four forked boards which are evenly distributed. The puncture needle is the needle which takes an appearance of T and is provided with a tiny channel at the inner side that deviates from the center. The working method is that: the local infiltration anesthesia is carried out, the empty needle tries to penetrate for implanting the fistulation tube into the bladder, the fistulation tube is fixed, the negative pressure urine drainage bag and the fistulation tube are connected, and the bladder puncture fistulation is completed.

Description

technical field [0001] The invention relates to a minimally invasive negative pressure cystostomy indwelling device and a working method thereof, belonging to the technical field of medical devices. Background of the invention [0002] The commonly used clinical cystostomy indwelling device is a double-lumen or triple-lumen Foley balloon silicone catheter connected to an ordinary urine bag to form a closed drainage, so as to quickly drain urine and prevent catheter blockage, and the diameter of the catheter is usually greater than 16F. This kind of drainage method requires the establishment of a large-caliber channel, which obviously has the following disadvantages: 1. The operation is risky and may cause massive bladder bleeding, so it is generally performed in the operating room of the hospital. Increase patient pain and treatment costs; 2. The larger the ostomy channel, the greater the trauma to the patient, and most of the patients who need cystostomy are elderly patient...

AI Technical Summary

Problems solved by technology

This kind of drainage method requires the establishment of a large-caliber channel, which obviously has the following disadvantages: 1. The operation is risky and may cause massive bladder bleeding, so it is generally performed in the operating room of the hospital. Increase patient pain and treatment costs; 2. The larger the ostomy channel, the greater the trauma to the patient, and most of the patients who need cystostomy are elderly patients with poor physical fitness, often combined with other diseases, surgical trauma and postoperative skin ostomy. Inflammation, swelling and pain often make patients unbearable; 3. The indwelling fistula tube is thick, which irritates the local tissues, especially the bladder tissue, resulting in cystitis and a large amount of secretions. Regular bladder irrigation is required, which increases the burden on patients; 4. The indwelling time of the fistula tube is short, and it needs to be replaced once a month in the hospital, otherwise it is easy to form stones and increase the chance of infection, and the replacement is often due to the deformation of the balloon part, which makes the local tube diameter thicker, which makes it difficult to remove and increases the pain of the patient; 5. After short-term cystostomy , due to the large stoma opening, the healing is slow; 6. The balloon catheter used as the stoma tube can only prevent the stoma tube from prolapse, but cannot limit its displacement into the bladder, which further aggravates the bladder irritation symptoms of the patient and the tissue around the stoma tube In addition, when the air bag ruptures, the catheter is easy to come out, causing burden to the patient and increasing the chance of infection

In order to solve many deficiencies in the existing commonly used cystostomy tubes, relevant searches have been carried out, and no one type of cystostomy tubes has been found that can better solve the existing problems
