[0002] Urine examination is a routine auxiliary means of clinical medical disease screening, and the urine sample should be a middle section urine sample.
[0003] At present, a cup and a test tube are generally used for urine sampling in hospitals, and the user needs to collect urine by first urinating, then holding back urine, and then urinating again after obtaining the sampling cup in the washroom. The whole urination process is contrary to the physiological process of natural urination of the human body, and the comfort degree is poor and the compliance is low.
[0004] The detection personnel pour the collected urine into the test tube for detection, but the urine sample in the test tube cannot be guaranteed to be middle section urine, most of which is a mixture of front section urine and middle section urine, which cannot accurately collect the middle section urine, and will affect the accuracy of the test result. At the same time, urine leakage is easy to cause pollution to the collector and the environment due to improper personal operation.
[0005] The middle section urine sampling cup in the prior art adopts a collection method of separating front section urine and middle section urine, and the front section urine is discharged to the sampling cup, and then a separation device (such as a baffle or a float) is used to block to separate the front section urine and the middle section urine. However, due to the influence of air pressure or air resistance, the separation effect of the front section urine and the middle section urine is not ideal, the middle section urine collection is not smooth, the collection amount is not constant, and the urine drips from the collection port to pollute the sampler or the environment, thereby causing errors in the test result.

Detailed Implementation
[0029] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.
[0030] Example 1
[0031] like Figures 1-2 , Figures 5-6 As shown, a midstream urine sampler with a vent includes a sampling cup 01 and a collection tube 02;
[0032] The sampling cup 01 is divided into a front urine collection cup 12 and a middle urine collection cup 13 by a partition 11 integrally formed in the middle of its inner wall. The front urine collection cup 12 and the middle urine collection cup 13 are connected by a through hole 14 in the middle of the partition 11. The partition 11 has a sampling air column 15 extending towards the mouth of the sampling cup 01. The front urine collection cup 12 is provided with a partition device. The middle urine collection cup 13 has an outlet on its side wall. The outlet forms an outlet tube 16 on the outer wall of the sampling cup 01. The outer edge of the outlet tube 16 has a fixing ring 17. The fixing ring 17 has a collection air column 18 extending towards the mouth of the sampling cup 01. The upper edge of the sampling cup 01 has a tilting notch 19. For easy installation, the lower end face of the front urine collection cup 12 and the side wall are respectively injection molded and snapped together.
[0033] The collection tube 02 is detachably connected to the sampling cup 01 and includes a tube cap 21 and a tube body 22. The tube cap 21 is threadedly connected to the tube body 22 and is fastened to the opening of the tube body 22. The tube cap 21 has an opening, the size of which is adapted to the fixing ring 17. The tube cap 21 has anti-slip texture. The collection tube 02 is connected to the outside through the outlet tube 16 and the collection air column 18. The collection tube 02 also includes an anti-backflow plate 23, which is set on the opening. The outlet tube 16 extends through the anti-backflow plate 23 into the tube body 22. To prevent the sample from leaking out and causing contamination during transportation, the tube cap 21 has a collection tube plug 24.
[0034] When collecting urine samples, the collector does not need to hold their urine; they can simply discharge the urine. The initial urine flows into the initial urine collection cup 12 through the through hole 14 on the partition 11. Once the initial urine collection cup 12 is full, the partition device closes the partition 11, and the sampling air column 15 prevents the partition device from closing the partition 11 prematurely due to pressure difference. The middle urine is in the middle urine collection cup 13 and is discharged into the collection tube 02 through the outlet tube 16. The collection air column 18 prevents the collection tube 02 from not being filled due to pressure difference. Once the collection tube 02 is full, the subsequent urine can continue to be discharged after the sampling cup 01 is removed. The excess urine in the middle urine collection cup 13 is poured out through the pouring notch 19. Pulling out the collection tube 02 completes the urine sample collection.
[0035] Example 2
[0036] like Figure 3 As shown, based on Example 1, the partition device is a float 03 installed in the urine collection cup 12 at the front end. The diameter of the through hole 14 is smaller than the diameter of the float 03. The float 03 is made of a material with a specific gravity less than water and / or has a hollow structure.
[0037] The buoyancy of the initial urine causes the float 03 to float up, and the float 03 blocks the through hole 14 to seal the partition 11. At the same time, the sampling air column 15 prevents the urine from flowing down due to excessive urine volume or rapid flow, which could cause the through hole 14 to become blocked.
[0038] Example 3
[0039] like Figure 4 As shown, based on Embodiment 1, the partition device is an overflow pool 04 formed by the middle of the bottom wall of the front urine collection cup 12 and extending towards the partition 11, and a through hole 14 extending into the overflow pool 04 to form a guide pipe 05. The lower edge of the guide pipe 05 is lower than the upper edge of the overflow pool 04 and does not contact the bottom of the front urine collection cup 12.
[0040] The front-stage urine flows into the overflow pool 04 through the flow guide pipe 05, and then flows out from the overflow pool 04 to the front-stage urine collection cup 12, and then flows into the current-stage urine collection cup 12, and after the urine collection of the current-stage urine collection cup 12 reaches a certain volume, the mid-stage urine is separated from the front-stage urine under the influence of a pressure difference and a backflow setting, the urine no longer flows downward, and the mid-stage urine flows into the collection pipe 02 through the outlet pipe 16.
[0041] The above merely describes the preferred embodiments of the present application and is not intended to limit the present application, and any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
