Boosting catheter of ureteral catheterization support

Abstract

The invention discloses a boosting catheter of a ureteral catheterization support, which belongs to the field of medical equipment and comprises a boosting tube; a tube groove A is fixedly mounted inthe center in the boosting tube, a through hole is connected in the boosting tube above and below the tube groove A, a fixed disc A is fixedly mounted at the right end of the boosting tube, and a threaded sleeve is movably sleeved on the outer wall of the boosting tube; a bearing is rotationally installed at the left end of the boosting pipe, a fixing disc B is rotationally installed at the left end of the bearing, an inserting groove is fixedly formed in the left end of the fixing disc B, an inserting block is inserted into the inserting groove, screw grooves A are fixedly formed in the innerwalls of the upper outer side and the lower outer side of the inserting block, and screw grooves B are fixedly formed in the upper portion and the lower portion of the fixing disc B. By arranging a rotating structure, an embedded fixing structure and a soft material, the practicability of the boosting catheter is improved.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to a boosting catheter of a ureteral catheterization stent. Background technique [0002] Medically, a catheter is inserted through the urethra into the bladder to drain urine. Urinary catheterization is divided into two types: indwelling catheterization and intermittent catheterization. The former catheterization is always indwelling in the patient’s body. The catheter should be pulled out as soon as the condition permits and must be replaced regularly. The latter catheterization is performed every 4-6 hours. Urinate once, catheterize immediately after the bladder is emptied, and need to use a booster catheter during the catheterization process. [0003] Patent CN201822247039.X has announced a new type of booster catheter for ureteral catheterization stents. During the process of ureteral stent placement, there is a common serious problem in this booster catheter, that i...

AI Technical Summary

Problems solved by technology

[0004] The above-mentioned booster catheter has some shortcomings: 1. The above-mentioned booster catheter is not convenient to select the corresponding plug shape to boost the catheter head according to the socket shape of the catheterization bracket, and can only produce different booster catheter plugs according to different catheterization bracket sockets. Increased cost and reduced availability of booster catheters

2. The above-mentioned booster catheter is manually pushed inward by the doctor during the process of boosting the catheterization stent, and the operation process is all based on the doctor's experience, and it is unavoidable that hand-held pushing will cause hand shaking, which increases Increased the difficulty of the operation, so that the doctor needs to be very tired. At the same time, the material of the above-mentioned booster catheter is relatively hard, which makes the patient uncomfortable and reduces the practicability of the booster catheter.
