Multifunctional urinary catheter

Abstract

The invention discloses a multifunctional urinary catheter. One end of a middle cavity is provided with a catheter tip that is of smooth sealed structure; the lateral side of the catheter tip is provided with side holes; a flexible balloon is arranged outside the middle cavity and is in communicated connection with an injection hole; the other end of the middle cavity is connected with one ends ofa first drainage cavity, a second drainage cavity and a pressure device; the pressure device is used for sealing the second drainage cavity; the other end of the pressure device is in communicated connection with the tail end of the urinary catheter and the other ends of the second and first drainage cavities; a clamp is arranged on the first drainage cavity and used as a switch; the pressure device can open and close the second drainage cavity. Compared with the prior art, the multifunctional urinary catheter made with the above structure by a manufacture method thereof can facilitate urination, can train the contractive function of the bladder; the material of the catheter herein can prevent bacteria and infections; the catheter herein is worthy of popularization and application.

Description

technical field [0001] The invention relates to a medical device, in particular to a multifunctional urination tube capable of inhibiting bacteria, preventing urinary tract infection, and automatically regulating urine discharge. Background technique [0002] During the examination and treatment of rescue surgery (such as: urinary retention, preoperative preparation, coma, urinary incontinence and perineal injury), it is often necessary to place a urinary catheter, especially in coma and critically ill patients, it may be necessary to place a urinary catheter for a long time. Most of the catheters commonly used at present are pipelines made of natural rubber, silica gel or polyvinyl chloride. Urethral injury, urinary tract infection, urinary catheter slippage, etc. may occur during placement or indwelling catheter. Urethral catheter placement can lead to mechanical damage to the urethral mucosa, and factors such as low immunity in patients can lead to bacterial invasion and...
