Lotus balloon urinary catheter with self-control urination function

Abstract

The invention discloses a lotus balloon urinary catheter with a self-control urination function. The lotus balloon urinary catheter comprises a guide head, a lotus balloon, a fixing part, a tube body,a control tube, a guide wire, a duplex connecting tube, a self-control valve and a urine bag connecting tube; a connector is arranged at one end of the tube body, the lotus balloon is arranged at theother end of the tube body, the guide head is connected to the tail end of the lotus balloon which is formed by combining multiple strip-shaped bodies, the strip-shaped bodies are straightened and form a tubular body with the same inner diameter and the outer diameter as the tube body in an enclosing mode, the connector is connected with the control tube, one duplex connecting tube is connected to the other end of the control tube, the self-control valve is connected to the other end of the duplex connecting tube, the urine bag connecting tube is connected to the other end of the self-controlvalve, the guide wire penetrates through the tube body, one end of the guide wire is connected with the control tube, and the other end of the guide wire is connected with the guide head. Accordingly, by means of the self-control valve, urination can be manually controlled, and the bladder contraction function is recovered conveniently. Different fixing parts can be selected according to the gender, fixation of the urinary catheter is firm, and urine leaking from the gap between the urinary catheter and the urethra can be collected.

Description

【Technical field】

[0001] The invention relates to the technical field of medical devices, especially the technical field of urinary catheters. 【Background technique】

[0002] A urinary catheter is a commonly used medical device. However, the monitoring data of medical device adverse events shows that "balloon cannot be inflated" and "balloon leaks and ruptures" leading to spontaneous slippage accounts for 80% of current adverse events of urinary catheter products. The balloon has become the main functional factor affecting the clinical use of urinary catheters. 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 ...
