Description

A liquid collection bag for mid-section urine collection

technical field

The present application relates to the technical field of medical devices, in particular to a liquid collection bag for mid-section urine collection.

Background technique

In clinical urine routine examination, or urine culture and drug susceptibility test, in order to prevent the collected urine specimens from being polluted by the genitals and affect the test results, it is necessary to take clean urine for examination and culture, so it is necessary to collect midstream urine.

At present, the commonly used urine collector for urinalysis is a urine cup. When using the urine cup to collect urine, it is necessary to move the urine cup to the urination place after the front end of the urine is discharged. Generally, the patient discharges the front part of urine after the urine is discharged. Use the urine cup to collect the middle urine, and for bedridden patients, another container is needed to collect the front urine, and then use the urine cup to collect the middle urine, and then use another container to collect the end urine , not only the cumbersome steps bring inconvenience to the use of patients or medical staff, but also the repeated exchange of urine containers can easily lead to untimely collection of urine in the middle section, affecting the accuracy of urine tests or causing unhygienic leakage of urine; Accurately know how much urine is collected, it is easy to take too little urine to meet the required amount of urine for the test, or to take too much urine due to the mixing of the front or end urine into the middle urine, which will affect the test results.

Although the patent "a middle urine collection device for laboratory use" (CN208958181U) published on June 11, 2019 also pointed out that the current urine cup has a simple structure and is inconvenient to use, and it is not easy for patients or nurses to grasp the middle urine collection device. The timing of urine collection, but the scheme adopted: "After the urine in the urine collection bottle in the first stage is full, the urine in the middle stage enters the urine collection bottle in the middle stage through the drainage tube for collection... the urine in the urine collection bottle in the middle stage is full After that, the remaining urine flows into the urinal through the overflow pipe.” This solution still cannot guarantee the accuracy of receiving the middle section of urine, and the medical staff or patients cannot control the amount of urine taken at each section by themselves. Too much or too little urine will affect the collection of mid-section urine; secondly, it cannot receive all urine, which is still inconvenient for some patients, especially those who need to be bedridden.
