Description

Technical Field

[0001] The invention relates to the technical field of postoperative auxiliary technology, in particular to a urinal catheter used for protecting a wound surface of a female vulva after surgery. Background Art

[0002] A urinary catheter is a tube that is inserted from the urethra into the bladder to drain urine. It is a tube made of natural rubber, silicone rubber or polyvinyl chloride, which can be inserted through the urethra into the bladder to drain urine. After the urinary catheter is inserted into the bladder, there is an air bag near the head of the catheter to fix the catheter in the bladder and prevent it from falling out. The drainage tube is connected to a urine bag to collect urine.

[0003] After undergoing vulvar surgery with a large wound, women need to use a urinary catheter to assist them in urination to avoid urine contaminating the wound and reduce the risk of infection. However, the catheterization time for traditional wound surgery generally takes three to five days, which causes urine to continue to adhere to the inner wall of the catheter. In addition, the inner wall of the catheter is relatively hidden and difficult to clean regularly, which makes it easy for urine to breed bacteria in the catheter, increasing the risk of urinary tract infection in patients, which is not conducive to postoperative recovery of patients. There is still a certain inconvenience in actual use. Therefore, there is an urgent need for a urinary catheter pot for protecting female vulvar wounds after surgery to solve the above problems. Summary of the invention

[0004] In order to overcome the above-mentioned technical problems, the purpose of the present invention is to provide a catheter for protecting female vulva wounds after surgery, so as to solve the problem that the catheterization time for traditional wound surgery mentioned in the above-mentioned background technology generally takes three to five days, which causes urine to continue to adhere to the inner wall of the catheter. In addition, the inner wall of the catheter is relatively hidden and difficult to clean regularly, which makes it easy for urine to breed bacteria in the catheter, increasing the risk of urinary tract infection in patients, which is not conducive to postoperative recovery of patients and still has certain inconveniences in actual use.

[0005] The present invention provides the following technical solution: a urinary catheter pot for protecting postoperative wounds of female vulva, comprising a urinary catheter mechanism, wherein the urinary catheter mechanism comprises a urinary catheter with urine inlets uniformly arranged at the ends and a urinary catheter container, wherein a cavity is arranged inside the urinary catheter container, and a urine outlet end of the urinary catheter is located in the cavity for collecting urine, wherein an air bag is wrapped on the outer side of the urinary catheter near the end, and a self-sealing air blowing end is connected to the outer side of the end of the urinary catheter, an air hole is opened on the inner wall of the outer side of the urinary catheter pipe, and the air hole connects the self-sealing air blowing end and the inside of the air bag, and is used for inflating the air bag, wherein the air hole is provided ... bag is provided with air. A urinary inlet tube is embedded and installed at the top of the urinary catheter container, a physiological saline bag is placed inside the cavity of the urinary catheter container, and the physiological saline bag has a connecting end, a magnet ring is embedded and installed on the inner wall of the urinary catheter container at the top of the physiological saline bag, an extrusion sheet is placed on the top of the physiological saline bag in the urinary catheter container, the outer edge of the extrusion sheet is covered with a rubber ring, and the outer surface of the rubber ring is in contact with the inner surface of the urinary catheter container for urine blocking, an iron sheet is embedded and installed inside the rubber ring for magnetic fixation with the magnet ring, and a handle is connected to the top of the extrusion sheet for auxiliary lifting;

[0014] To implement the above technical solution, the liquid-blocking sheet will be closely attached to the liquid-passing sheet when impacted, thereby preventing the flushing saline from entering the patient's bladder from the urine inlet.

[0015] Furthermore, a fixing ring is connected to the inner wall at the end of the water pipe, a first spring is connected to one side of the fixing ring, and a rubber ball is connected to the other end of the first spring. The rubber ball is located outside the water pipe, and the outer diameter of the rubber ball is larger than the inner diameter of the water pipe.

[0016] The above technical solution is implemented to prevent urine from entering the water conduit.

[0017] Furthermore, the connecting mechanism includes a rubber seat, which is inserted into the urine inlet tube. A urine inlet sheath is embedded and installed on the rubber seat. The urine outlet end of the catheter is connected to the rubber sheath, and the two are internally connected. The rubber sheath is movably connected to the outside of the urine inlet sheath for guiding urine.

[0021] Furthermore, the communication mechanism also includes another type of rubber seat, a funnel sleeve is embedded and installed on the top end of the rubber seat, and the two are internally connected.

[0022] Implementing the above technical solution makes it convenient to directly use the rubber seat for urination.

[0023] Technical effects and advantages of the present invention:

[0024] 1. The present invention uses a urinary catheter to guide urine into a urinary catheter container to collect urine, and cooperates with the squeezing sheet to be pressed down by the weight of urine to a critical value, so that the physiological saline bag is squeezed, allowing the water to enter the catheter and automatically flush the inner wall of the catheter.

[0025] 2.

[0037] The self-cleaning mechanism 2 includes a double-pass seat 210, which is embedded in the bottom of the outer side of the catheter container 110. The double-pass seat 210 is movably sleeved and fixed with a connector 211 at the end of the outer side of the catheter container 110, and the end of the double-pass seat 210 located on the inner side of the catheter container 110 is connected to the connecting end of the physiological saline bag 118, and the end of the connector 211 is connected to a water pipe 212, and the two are connected inside. The body of the water pipe 212 is embedded in the inner wall of the catheter 111, and the water outlet end of the water pipe 212 extends to the inside of the catheter 111.

[0038] The connecting mechanism 3 is arranged in the urine inlet 116. The urine catheter container 110 is divided into a pot body and a pot cover detachable at the top thereof, and a rubber skin is arranged at the open end of the pot body for sealing and squeezing and fixing the two, for internal cleaning and continuous replacement of the physiological saline bag 118.
