Abstract

The invention relates to medical equipment for urinary catheterization, in particular to a urinary catheter capable of achieving a long-acting sustained-release administration function and a production method thereof, and aims to solve the problems that an introduced drug coating layer in the prior art is prone to falling off, low in drug carrying capacity, too fast in drug release and the like. The urinary catheter comprises a main urinary catheter body, wherein the main urinary catheter body is provided with at least one groove formed by a laser processing process, and the opening of the groove is located in an area, contacting with the human body, on the outer wall of the urinary catheter. Compared with the prior art which coats the outer surface of the main urinary catheter body with adrug, the urinary catheter has the advantages that by arranging the grooves in the main urinary catheter body, the drugs loaded into the grooves are less prone to falling off, the specific surface area of the main urinary catheter body is increased, and the main urinary catheter body can contain more drugs.

Description

technical field [0001] The invention relates to a medical device for urinary catheterization, in particular to a urinary catheter capable of realizing the function of long-acting sustained release drug delivery and a preparation method thereof. Background technique [0002] A urinary catheter is a tube that is inserted into the bladder from the urethra to drain urine. After the catheter is inserted, due to various reasons, it may cause side effects such as urethral bleeding, infection, and atrophy, especially for patients with long-term catheterization. , the probability of side effects is higher; in addition, due to treatment requirements or in order to reduce the occurrence of side effects, it is necessary to replace the catheter several times, which not only brings great pain and economic burden to the patient, but also increases the burden on the medical staff. workload. [0003] In the prior art, in order to reduce or avoid the occurrence of side effects, various antib...
