Description

An improved urinary catheter that is convenient for collecting mid-section urine

Technical field

The utility model relates to the technical field of medical appliances, and specifically relates to an improved urine catheter that is convenient for collecting mid-section urine.

Background technique

Urine examination is a medical testing method. Urine examination is of great value for clinical diagnosis, judgment of therapeutic effect and prognosis. In the urine test, the urine in the urinary tube needs to be collected. In order to improve the accuracy of the test, the urine test mainly collects the middle section of the urine for testing.

The current method of mid-segment urine collection is that medical staff first instruct the patient to hold back the urine, allowing part of the front-segment urine to flow into the urine bag first, then use a traditional clamp to clamp the urinary catheter, and then use a syringe needle or scalp needle to insert into the urinary catheter to drain and collect the urine. The collected urine is then poured into the collection tube. This collection method can easily cause the urine to be re-contaminated and affect the accuracy of urine testing. At the same time, medical staff need to use a large number of tools to collect urine. The operation is time-consuming and labor-intensive, which greatly increases the cost of urine collection. The workload of medical staff affects the efficiency of urine collection.

In view of this, the applicant conducted in-depth research on the above issues, and this case emerged.
