Description

Retractable double-layer closed bottom open quantitative urine collector

Technical field

The utility model relates to the technical field of a medical device for collecting urine specimens, in particular to a retractable double-layer closed bottom open quantitative urine collector.

Background technique

Urine testing can understand human body water, electrolytes, acid-base balance, infection, stones, inflammation, kidney disease, etc. Through the understanding of urine composition and traits, specific gravity, pH, cells, bilirubin, etc., can reflect The metabolism of the human body and the functional status of various important organ systems are the first choice for human disease diagnosis, efficacy analysis, prognosis judgment, and health assessment. With the popularity of medical insurance and the health needs of the whole society, the number of urine tests is still According to statistical materials, there are about 600 million urine test workloads in 2015. According to the current national expert on urine test and analysis, urine tests have clear requirements from the collection container of the specimen to the collected urine volume. The urine testing equipment directly on the machine is becoming more and more popular, as well as the control requirements of the national hospital infection. The traditional collection of urine tools is likely to cause contamination of the patient's fingers during the collection process, and then cross-infect the door handle, inspection documents, and scattered. The urine will also pollute the ground, causing dust to fly, polluting the hospital's ambient air, and opening, open urine cups. The environment of the odor pollution inspection department needs to be transferred to the centrifuge tube by the inspection doctor twice, and then the machine is taken. This method of urine collection is similar to the current situation in Japan, Korea, Europe and the United States, and Taiwan in China. There is a problem that the standardization and the degree of civilization do not match. Many domestic and foreign urine collection inventions have not solved the problems of urine scattering, absolute quantification, splashing on the fingers when taking urine;

According to the survey: urine and corridor floors, door handles, and even inspection sheets have been found to be contaminated with urine to varying degrees. These are due to open plastic cups, paper cups, and open test tubes used to collect urine. Or the exposure of the open cup on the way to the laboratory, the pollution caused by urine collection is one of the three major causes of infection in the hospital;

The use of traditional open plastic cups and open test tubes requires hand-held cups, especially for female patients, children, and elderly patients. It is very difficult to collect urine, and the collection of urine is not good, and it is easy to splash the hands. Cross-infection by hand contact with door handles, coins, and inspection orders;

After searching, various funnel style urine cups have not been shaken off, that is, they have not got rid of the urine splashing hands. In addition, the hand-held funnel collects urine, and when the female urination is urinating, the amount of urine cannot be observed and it is difficult to obtain. The appropriate position of the lower position of the test tube low-pitched funnel is not full of urine overflowing. The test tube is not enough urine. It needs to take urine again. There are some techniques for adsorbing urine with inert materials. There are many questions in the industry: large cells in the urine and Whether the tube type has more suction and less adhesion, and when the adsorbent material is compressed and extruded into the urine, the large cells and the tube type are crushed and crushed at the same time, and the amount of urine taken is affected by the adsorbate and the adsorption speed, resulting in The collection of urine volume is not very accurate and does not reach the absolute quantification. These problems, which affect the objectivity, accuracy and convenience of the test results, have always been the confusion of the test and clinicians.
