Description

An improved urinalysis indwelling tube

technical field

The utility model relates to the technical field of medical devices, in particular to an improved urine analysis indwelling tube.

Background technique

Urine specimen is a kind of test material that can be easily obtained in clinic, and the change of its composition can not only reflect the pathological changes of the urogenital system, but also reflect the systemic disease status. Therefore, urinalysis is a commonly used clinical examination item.

For patients with indwelling catheterization, one of the commonly used methods for collecting urine specimens is to drain urine into the specimen container at the drainage hole under the urine collection bag. This method is simple and easy to implement, but if the urine in the urine bag remains A long time may affect the results of urinalysis and affect the accurate diagnosis and timely treatment of the disease. Another method is to first clamp the small clip on the urine collection bag, then sterilize the end of the catheter connected to the urine collection bag with iodophor, connect the syringe with a scalp needle, and puncture the catheter with the scalp needle in a sterile manner. At the end of the tube, draw urine through a syringe, then pull out the scalp needle, and inject the urine in the syringe into the urine sample container. Although the urine extracted by this method is relatively fresh, a syringe needs to be connected, and the urine may be splashed when the urine is injected into the specimen container, and the operation is relatively complicated.

Therefore, it is particularly important to design an indwelling catheter that not only ensures the quality of urine, but also streamlines the operation process of nurses and improves work efficiency for urine analysis and collection of patients with indwelling catheterization.
