Description

Technical Field

[0001] This utility model relates to the field of urinary catheter technology, and in particular to a urinary catheter that is easy to disassemble. Background Technology

[0002] Traditional urinary catheters often have complex balloon deflation valve designs or inconvenient connection methods (such as overly tight threads or easy adhesion), leading to lengthy disassembly times and potentially causing urethral injury due to improper operation. After deflation, insufficient balloon collapse may occur due to insufficient material elasticity or a rough surface, increasing resistance during catheter removal. Patient discomfort and complication risks are also a concern. The hard material or high surface friction coefficient of traditional catheters can easily cause urethral mucosal damage, pain, and even urinary tract infections (UTIs) if left in place for extended periods. During removal, adhesion between the catheter and urethra or incomplete balloon deflation can lead to urethral tears, bleeding, or catheter breakage and residue. Finally, the cumbersome disassembly process of traditional urinary catheters, especially in emergencies (such as those requiring rapid replacement due to infection) or after long-term indwelling, increases the difficulty of operation and the burden on medical staff. The background technology of easily removable urinary catheters (such as LK catheters) primarily addresses the problems of difficult removal, numerous complications, and patient discomfort associated with traditional catheters. Through innovative designs such as rapid deflation balloons, optimized interface connections, hydrophilic / antibacterial coatings, and radiopaque markings, they achieve safe and efficient placement and removal. Their core technological goal is to balance ease of operation, patient safety, and clinical practicality, making them suitable for catheterization needs in various medical scenarios. (Related comparative documents searched) Urinary catheters are widely used in the medical field to help patients drain urine. However, traditional urinary catheters often present problems such as complex operation and inconvenience during disassembly. For example, some urinary catheters have relatively fixed connection structures that are difficult to separate quickly, and disassembly may require considerable force and complicated procedures. This not only increases the workload of medical staff but may also cause additional discomfort to patients. Therefore, we propose a urinary catheter that is easy to disassemble to solve this problem.

[0005] Preferably, the quick-release assembly includes: a sliding round rod and a slanted buckle. The slanted buckle is slidably installed inside the inserting round rod, and the sliding round rod is fixedly installed at the top of the slanted buckle. A fixing spring is fixedly installed on one side of the slanted buckle, and the fixing spring is fixedly installed inside the inserting round rod. A limiting hole matching the slanted buckle is provided on the connecting base block. A moving groove matching the sliding round rod is provided on both the inserting round rod and the limiting round plate. A plurality of arc-shaped holes are provided on the rotating disk, and the sliding round rod moves and abuts against the arc-shaped holes.

[0006] Preferably, the second connecting component includes: a plurality of rotating blocks and an outer limiting frame. The plurality of rotating blocks are fixedly installed at the bottom end of the connecting bottom block. A connecting sealing pressure plate is rotatably installed on the rotating block. A limiting pressure plate is integrally formed at the top end of the connecting sealing pressure plate. The bottom end of the limiting pressure plate is movably abutting against the top end of the connecting top block. The outer limiting frame is slidably installed on the connecting steel pipe. An extrusion groove matching the connecting sealing pressure plate is opened on the outer limiting frame. The bottom end of the connecting sealing pressure plate is movably abutting against the bottom end of the extrusion groove.

[0007] Preferably, an air vent is provided on one side of the outer rubber hose, an inflation tube is fixedly installed inside the air vent, an inflation bladder is fixedly installed on one side of the inflation tube, a sealing valve is fixedly installed on the inflation bladder, and the inner rubber hose is disposed inside the outer rubber hose.

[0008] Preferably, a T-shaped ring is fixedly installed at the top of the rotating disk, a T-shaped groove matching the T-shaped ring is opened at the bottom of the connecting top block, an L-shaped ring is integrally formed at the bottom of the rotating disk, and the rotation-restricting circular plate is installed in the L-shaped ring.

[0009] Preferably, the outer limiting frame has a limiting groove that matches the angled buckle, the connecting bottom block has an installation groove that matches the insert rod, the insert rod has a sliding square groove that matches the angled buckle, the angled buckle is slidably installed in the sliding square groove, and the fixing spring is fixedly installed in the sliding square groove.

[0010] Preferably, a circular rod is fixedly installed on the rotating block, and a rotating hole matching the circular rod is opened on the connecting sealing pressure plate, and the connecting sealing pressure plate is rotatably installed on the circular rod.

[0011] In this utility model, a detachable urinary catheter is provided. When the urinary catheter is in normal use, the outer and inner rubber hoses together form a urine transmission channel. Through the cooperation of the sealing valve and the inflation balloon, the inflatable hose portion of the urinary catheter expands, thereby fixing the position of the urinary catheter in the bladder. The upper connecting block, connecting top block, rotating disk, limiting circular plate, inserting circular rod, and the rotating block, connecting sealing pressure plate, and outer limiting frame in the second connecting assembly cooperate with each other to ensure the connection stability between the various parts of the urinary catheter. These structures work together to ensure that the various parts of the urinary catheter are tightly connected and remain stable. When disassembling, first, open the sealing valve on the inflation balloon to release the gas in the inflation hose, causing the inflation hose to shrink. Then, slightly move the rotating disk to disengage the angled buckle from the outer limiting frame, and at the same time, its compression groove disengages from the bottom end of the connecting sealing pressure plate. In this utility model, a detachable urinary catheter is constructed by a connecting sealing pressure plate that rotates downwards around a circular rod on a rotating block under its own weight or slight external force. This causes the limiting pressure plate at its top to disengage from the top of the connecting top block. Then, as the rotating disk rotates, the sliding rod moves within the arc-shaped hole of the rotating disk, thereby driving the sliding rod. The sliding rod causes the oblique buckle to slide within the sliding square groove of the insertion rod, disengaging the oblique buckle from the limiting hole of the connecting bottom block. Due to the rotational connection between the rotating disk, the limiting circular plate, and the insertion rod, the insertion rod is gradually pulled out from the mounting groove of the connecting bottom block. Finally, when the insertion rod is completely pulled out from the connecting bottom block, the inner rubber hose, upper connecting block, connecting top block, rotating disk, limiting circular plate, outer rubber hose, and connecting bottom block can be separated, completing the disassembly of the urinary catheter. This utility model has a reasonable structural design. By setting up a quick-release assembly and a second connecting assembly, when it is necessary to disassemble the urinary catheter, the various parts of the catheter can be quickly separated by simply following the operating steps. This greatly simplifies the disassembly process and improves the efficiency of disassembly. During the disassembly process, there will be no sudden breakage or splashing of parts, which ensures the safety of medical staff and patients. At the same time, the sealing valve design of the inflatable balloon can effectively control the inflation and deflation of the balloon, avoiding accidents caused by balloon problems.
