Technical Field
The invention relates to a sampling device, in particular to a human urine sampling device.
Background
The human urine detection result is used as a judgment basis and is widely applied to aspects such as disease diagnosis, stimulant test, drug absorption verification and the like, so the human urine collection behaviors occur all over the world and are huge in number.
At present, the urine collection method commonly used by people all over the world is as follows: the disposable cup-shaped container is held by a hand and is placed near the urethral orifice to contain urine, and the urine in the container is subpackaged into test tubes after defecation is finished for various detections; urine collection relies on the experience of people to complete the operation process. It is known that such urine collection methods have the following drawbacks and disadvantages: firstly, the capacity of a disposable cup-shaped container is limited, when the defecation amount is larger than the capacity of the cup-shaped container, the urine filling amount in the cup needs to be controlled, if the excessive urine overflows out of the cup, the cup body and a human body are polluted, the manual control action of the filling amount interferes the defecation process, and normal defecation is influenced. Secondly, the opening of the disposable cup-shaped container is small, the defecation containing direction and the cup opening position need to be adjusted and controlled simultaneously, urine leakage caused by misoperation is difficult to avoid, and pollution is brought to human bodies and clothes. And thirdly, the test tube for urine detection cannot directly collect a urine sample, and needs manual secondary subpackaging. And fourthly, the urine sample collection process is poor in experience, the defecation direction, the position of the cup opening, the defecation amount and the factors for subpackaging the urine into the test tube and the like are manually controlled, misoperation is easy to occur, pollution and inconvenience are brought, and the people can feel embarrassed, nervous and the like.

When the disposable urine collecting cup is used, the caliber formed by the enlarged expansion of the wide opening of the liquid collecting funnel is far larger than that of the disposable cup-shaped container, so that urine can be contained conveniently, and urine leakage is avoided to pollute human bodies and clothes. The invention is provided with a step flow guide device, the step flow guide device is provided with a guide pipe, liquid collected by a liquid collection funnel can respectively flow through a step a, a step b and a step c under the action of gravity through the guide pipe, and the collection of human urine samples is automatically completed through a flow dividing pipe, a sampling pipe, a waste liquid pipe and a one-way valve device on the flow dividing pipe, which are sleeved on the step a, the step b and the step c. When the urine sampling device is used, the one-way valve device can automatically shunt and isolate front-section urine, and sampling of a middle-section urine sample can be automatically completed. The invention has simple operation and convenient use, and can be used by a user for normal defecation without interrupting the defecation or controlling the defecation direction and the defecation amount, thereby completely avoiding urine leakage from polluting human bodies, clothes and environment. The invention adopts a humanized design concept, overcomes the defect that the disposable cup-shaped container needs to be used for subpackaging urine into the test tube, and the test tube for urine detection can directly collect a urine sample meeting the detection requirement without manual secondary subpackage. This device simple structure, reasonable in design, the drawback of easy misoperation that takes place when having overcome disposable cup container collection urine sample is convenient for operate, and urine sample collection process operation is experienced well, can not produce unfavorable emotions such as awkwardness, tension.

Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1 to 3, in the embodiment of the invention, a human urine sampling device comprises a liquid collecting funnel 1 and a step flow guide device 3, wherein the liquid collecting funnel 1 is made of a flexible foldable material, an elastic band 2 is arranged at a wide opening at the upper end of the liquid collecting funnel 1, the elastic band 2 is made of an elastic material and has extensibility and resilience, the wide opening is expanded, and the elastic force of the elastic band 2 can fix and hang the device. The lower end of the liquid collecting funnel 1 is connected with a step flow guide device 3, the step flow guide device 3 comprises a step a, a step b, a step c, a guide pipe 4, a shunt pipe 6, a sampling pipe 7 and a waste liquid pipe 8, the step a, the step b and the step c are in a step-shaped relation from high to low, through holes are formed in the step a, the step b and the step c, the bottom of the step a, the bottom of the step b and the bottom of the step c are respectively connected with the shunt pipe 6, the sampling pipe 7 and the waste liquid pipe 8 through thread matching, the upper end of the guide pipe 4 is connected with a small opening at the lower end of the liquid collecting funnel 1 and used for guiding liquid contained in the liquid collecting funnel 1 into the shunt pipe 6, the guide pipe 4 passes through the through hole formed in the step a and extends to the upper part of the shunt pipe 6, the port diameter of the lower end of the guide pipe 4 is, the sampling tube 7 is sleeved on the step b, can be screwed down through threads and is used for collecting a liquid sample, and the waste liquid tube 8 is sleeved on the step c and is used for draining the unnecessary liquid. After shunt tubes 6 flowed into quantitative liquid, automatic closure can be realized to check valve device 5 under intraductal liquid buoyancy, and then the liquid that continuously flows into in this device spills over step a, flows to next stage step b under the action of gravity, flows into in the sampling pipe 7 on step b is located to the cover, after sampling pipe 7 collected full liquid sample, the liquid that spills over flowed out from step b, flows to next stage step c to locate waste liquid pipe 8 on step c through the cover and discharge. And (4) after defecation is finished, taking down the sampling pipe 7 from the human urine sampling device for inspection, and finishing urine sampling.
