AI Technical Summary
After the existing catheter airbag is injected with water, the outside is spherical, which causes the contact surface between the airbag and the bladder to be small, and the urethra cannot be effectively closed, resulting in urine leakage problem. Especially in elderly women and other patients with urethral relaxation, the urine leakage rate is high, which increases the patient's Risk of skin damage, reduce comfort and extend hospital stay.
A urinary leakage-proof catheter is designed, using an expansion mechanism and a water supply member. By filling the corrugated telescopic tube with water, the arc-shaped expansion sheet expands, forming a transverse elliptical expansion capsule, increasing the contact surface with the bladder and improving closure. Effects, and a sample sampling port is set on the catheter for easy urine detection.
Through the design of the expansion mechanism, the contact surface between the catheter and the bladder is increased to effectively prevent urine leakage, and simplify urine detection through the sample sampling port, improving patient comfort and nursing efficiency.

[0002] Indwelling urinary catheter is one of the commonly used methods for diagnosing and treating diseases in clinical practice. Its main purpose is to solve the problem of patients being unable to urinate on their own, drain urine, and observe the amount and nature of urine. It is beneficial for the diagnosis and treatment of clinical diseases, guiding medication, observing changes in the condition, and judging the efficacy.
[0003] After the existing urinary catheter balloon is filled with water, the exterior becomes "spherical", resulting in a smaller contact area between the balloon and the bladder. For patients with urethral relaxation, such as elderly women, the internal urethral opening cannot be effectively sealed, resulting in urine leakage. The longer the catheter is indwelling, the higher the incidence of urine leakage. Urinary catheter leakage increases the risk of damage to the patient's perineal skin and mucous membrane, reduces comfort, leads to urine record errors, prolongs hospitalization time, increases the care burden on family members and the workload of nurses. In addition, when sampling urine samples, it is necessary to draw from the urine bag, which is inconvenient to operate. Therefore, it is necessary to design a leakage-proof urinary catheter to improve the above-mentioned problems. Utility Model Content

By setting the expansion mechanism 8 in the expanded state, the expansion bag 3 can be made into a transverse elliptical shape, thereby greatly increasing the contact area between the expansion bag 3 and the bladder, thereby achieving the purpose of preventing urine leakage.

One side of the arc-shaped expansion piece 803 is fixedly connected to the inner wall of the expansion bag 3. Water is filled into the bellows expansion tube 802 through the water supply component 4, so that the bellows expansion tube 802 is extended, and the arc-shaped expansion piece 803 is driven to expand outward by the extended bellows expansion tube 802. The arc-shaped expansion piece 803 is located in the middle of the expansion bag 3, so that the middle of the expansion bag 3 is expanded first, so that the expansion bag 3 becomes a transverse elliptical structure, which can increase the contact surface between the expansion bag 3 and the bladder, improve the sealing effect on the patient's urethra, and prevent urine leakage.

Water is injected into the water inlet pipe 402 through a syringe or other water injection tool, and the water is transported to the dispensing tube 401, and then dispersed and transported to the bellows telescopic tube 802 through the dispensing tube 401. The bellows telescopic tube 802 is filled with water, thereby extending the bellows telescopic tube 802, and the arc expansion piece 803 is driven to expand outward by the extended bellows telescopic tube 802.
