Problems solved by technology
Clinically, the main causes of balloon leakage and rupture are that the medical staff mistakenly used petroleum-based lubricants to corrode the balloon, or injected more than the nominal volume of normal saline, making the balloon unbearable, or the balloon collided during the operation. Touching sharp objects, or acid-base corrosive substances such as tweezers used for lubrication, urethral stones, etc., the above situations are difficult to control and prevent in clinical operations

The invention discloses a lotus-shaped balloon catheter which comprises a guide head, a lotus-shaped balloon, a tube body, a control tube, a guide wire and a urine bag connecting tube. A joint is arranged at one end of the tube body, the lotus-shaped balloon is arranged at the other end of the tube body, the guide head is connected at the tail end of the lotus-shaped balloon, the lotus-shaped balloon is formed by a plurality of strip-shaped bodies, the strip-shaped bodies form a tubular body identical to the tube body in inner diameter and the outer diameter after being straightened, the jointis connected with the control tube, the other end of the control tube is connected with the urine bag connecting tube, the guide wire penetrates through the tube body, and one end of the guide wire is connected with the control tube. According to the shape change principle of stretching and shrinkage actions, the mode of combining a movable corrugated tube and the guide wire to perform design, the guide wire for traction is arranged in a conventional catheter body, the 'hidden balloon' consisting of the strip-shaped bodies is made on the tube body, the guide wire is pulled to perform reciprocating motion through stretching and shrinkage of the movable corrugated tube, and accordingly the 'hidden balloon' forms a 'lotus' stretching and shrinking freely.
Description
【Technical field】 [0001] The present invention relates to the technical field of medical devices, in particular to the technical field of urinary catheters. 【Background technique】 [0002] A urinary catheter is a commonly used medical device. However, the monitoring data of adverse events of medical devices shows that the phenomenon of "balloon can not be inflated", "balloon leaks and ruptures" leads to self-slippage, which accounts for 80% of the adverse events of current catheter products. Balloon has become the main functional factor affecting the clinical use of urinary catheters. Clinically, the main reasons for the leakage and rupture of the balloon are that the medical staff mistakenly used the petroleum-based lubricant to corrode the balloon, or injected more than the nominal saline volume, which made the balloon unbearable, or the balloon touched during the operation. Touching sharp objects, or acid-base corrosives such as tweezers used for lubrication, urethral s...
