Background technique

Urinalysis is a common auxiliary method for clinical medical disease screening. According to the requirements of the "Health Industry Standard Ws/T348-011 Guidelines for the Collection and Processing of Urine Specimens of the People's Republic of China", the urine sample submitted for inspection should be "middle urine sample" to ensure The liquid test data in the tested urine is accurate.

However, the current clinically used urine collection device is generally a urine cup with a test tube for the patient to collect by himself. This device makes it difficult for the patient to control the sampling. It can only collect mixed urine or the front part of the urine, which cannot guarantee all urine samples. The collected urine sample is middle urine, and it is easy to cause urine overflow to pollute the patient and the environment.

In order to collect mid-section urine samples, several technologies have been announced in the industry, such as: (1) CN206132447U, "A Urine Collection Device", this technology can only collect urine samples into test tubes at one time, and cannot collect them in sections Mid-section urine sample; (2) ZL201620666207.7, "Storage Type Mid-section Urine Sample Sampling Device". (3) CN106769231A, "A kind of urine sampler that is convenient to take liquid in different stages", a valve is designed to cut off and control the urine segmentation, the valve will be manually controlled, which is inconvenient to operate.

Therefore, developing a simple, accurate and automatic mid-section urine sample collection device has become an urgent problem to be solved in the industry.

When using this embodiment, the subject holds the middle urine sample collection tube 11 with his hand, urinates into the receiving cup 3, the initial urine enters the receiving cup 3, enters the initial urine collection cup 4 through the communication port 5, and then As the urine level rises, the blocking float 6 rises until the connecting port 5 is blocked. At this time, the initial urine has been stored in the initial urine collection cup 4; the urine that the subject continues to discharge is the middle urine. Urine, the middle urine gradually accumulates in the receiving cup 3, when the urine level reaches the middle urine sample outlet 7, the middle urine flows into the interlayer cavity 2 through the middle urine sample outlet 7, and then passes through the middle urine sample transfer port 9. The connection nozzle 17 and the connection inlet 15 enter the middle urine sample collection pipe 11. During this process, the air in the middle urine sample collection pipe 11 is discharged through the exhaust hole 16; when the urine is filled with the middle urine sample After the collection tube 11, excess urine is accumulated in the interlayer chamber 2, and the subject continues to urinate until the end. If the subject urinates a lot and exceeds the capacity of the interlayer cavity 2, the excess urine overflows out of the cup through the urine overflow port 8; after the urination is completed, turn this embodiment over and pour out the remaining urine in the inner cup and the outer cup 1. Liquid, just unplug the collection tube cap 10 and the middle urine sample collection tube 11 from the middle urine sample transfer port 9 and send it for inspection. The entire urination process of the subject does not need to be interrupted, and can be completed continuously, and the middle urine sample automatically enters the middle urine sample collection tube 11 . The middle urine sample collected by using this embodiment is accurate, the method is simple, and the existing method avoids the problems that the urine splash pollutes the subject and the environment and cannot guarantee the accurate collection of the middle urine sample.

The above descriptions are only preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included in the scope of the present invention. within the scope of protection.
