Description

A urinary catheter that can be used for drug therapy

technical field

The utility model relates to the field of medical equipment, in particular to a urinary catheter which can be used for drug treatment.

Background technique

Urinary catheter is a commonly used medical device, mainly used for patients with urinary incontinence or disabled persons with paraplegia and quadriplegia. Since such patients cannot control urination independently, inserting a catheter can help them urinate safely and effectively. Urine is stored in the empty bladder.

In actual use, the urinary catheter often needs to be left in the patient's body for a long time, and the longest indwelling time can reach 30 days. In order to avoid urethral inflammation of the patient during this period and to achieve the purpose of treatment, a drug coating is usually arranged on the surface of the urinary catheter. However, it is difficult for this drug coating to achieve continuous drug administration during the catheter indwelling period. Due to the peristalsis of human tissue, the drug coating is often wiped off before the catheter indwelling period expires, thus exposing the patient to bacteria Among the risk of infection, and affect the efficacy of treatment.

At the same time, long-term use of the urinary catheter will cause damage to the urethral mucosa and secondary bleeding. However, if the urinary catheter cannot be removed, there is currently no feasible drug treatment for this damage.
