Description

A urethral indwelling continuous drug delivery device

technical field

The invention mainly relates to the field of urology, in particular to a urethral indwelling continuous drug delivery device.

Background technique

Male urinary system diseases have always been an important problem that plagues men's physical health. Problems in the male urinary system often lead to external symptoms such as frequent urination, urgency, dysuria, and urinary incontinence, and may also be accompanied by high blood pressure, edema, and anemia. and other symptoms, which seriously endanger the physical and mental health of men. In severe cases, male urinary tract infection and urethral inflammation can lead to serious health problems such as urethral damage and pus discharge, and urethral adhesions, which greatly affect the physical health of men. At present, the treatment methods for urethral inflammation mainly include oral administration of anti-inflammatory drugs, subcutaneous injection of anti-inflammatory drugs and urethral administration. The active ingredients of these two methods of oral anti-inflammatory drugs and subcutaneous injection of anti-inflammatory drugs need to pass through the digestive system or the lymphatic system. In order to reach the inflammation site, the effective time is long, and the patient’s recovery is slow. Although the urethral administration method allows the drug to directly contact the affected area, due to the special physiological structure of men, the drug is not easy to indwell in the male urethra, which also affects the treatment effect. Just like the invention patent with the application number of CN201610020154.6 and the title of "a urethral applicator for urology", the urethral inflammation is treated by injecting medicine into the urethra. After the medicine is injected into the patient's urethra, it cannot Long-term retention in the urethra, the treatment effect is not ideal.

To sum up, there are still problems of slow effect, long recovery time, unsustainable urethral administration, and unresolved urethral adhesions for male urethral inflammation.
