Description

Technical Field

[0001] The invention relates to the technical field of urology, in particular to a leakage-proof urinary catheterization device for urology nursing. Background Art

[0002] In the clinical nursing work of urology, catheterization is a common and important operation aimed at helping patients to discharge urine smoothly. It plays a key role in the treatment of various urinary system diseases and the postoperative recovery of patients.

[0003] Traditional urinary catheter devices have gradually exposed some problems in practical applications. First of all, it is often difficult to achieve an ideal sealing effect at the connection between the catheter and the urethra. Due to the physiological structure characteristics of the human urethra and individual differences among patients, urine is easy to seep out from the connection between the catheter and the urethra after the catheter is inserted. This will not only cause the local skin of the patient to be moist for a long time, increase the risk of complications such as skin infection and urinary tract infection, but also cause discomfort to the patient, affecting his recovery experience and quality of life.

[0004] Secondly, the connection method between the urinary catheter and the subsequent catheter used to collect urine (such as the catheter connected to the urine collection bag) also has certain shortcomings. Some existing devices are cumbersome to operate during connection, and the stability and sealing of the connection are sometimes difficult to ensure. The connection may become loose, causing urine leakage, or it may not be able to effectively achieve self-sealing when not in use, allowing bacteria and other pathogens to enter the urinary catheter through the connection site, thereby causing urinary system infection.

[0005] In addition, during the catheterization process, the rate of urine discharge may sometimes be less than ideal if it relies solely on the patient's own physiological urination mechanism and the natural drainage of the catheter. Especially for some patients with certain urination dysfunctions, this may cause urine to accumulate in the urinary system, further aggravating the patient's discomfort and the burden on the urinary system.

[0020] 1. The leak-proof catheterization device for urological surgery nursing has a leak-proof component that is attached to the outside of the urethral opening through a sealing cover to provide a certain degree of sealing. The expansion tube is made of elastic silicone and can be turned by turning the knob to drive the screw to rotate, so that the piston plate is pressed down to squeeze the air in the cylinder into the expansion tube to expand it outwards and fill the gap in the urethral opening, thereby greatly improving the sealing of the connection between the catheter and the urethra and effectively preventing urine from leaking from the connection between the catheter and the urethra.
