Two openings 112 realize connection.
Urine capture system 20 provided by the utility model, when it, which is applied to closestool, carries out urine capture, sampling valve 21
It is arranged in the urinal of closestool, is used to sample the urine in closestool；Since switch valve 10 is connected to sampling valve 21, urine
Sample can flow at switch valve 10 along the pipeline between sampling valve 21 and switch valve 10.When needing to collect urine specimen
When, acquisition device 22 is opened the switch valve 10 and can be extracted in closestool so that sampling unit 21 is connected to acquisition unit 22
Urine.Also, switch valve 10 is normally closed type switch valve, can prevent extraneous bacterium or dust granule access switch valve 10, from
And reduce the pollution to urine capture, and then improve the accuracy of urine detection.
In the above-described embodiment, optionally, the working condition of urine capture system 20 includes sampling state and cleaning shape
State.When acquisition device 22 receives sampling instruction, acquisition device 22 is used to push spool 12 along far from the first opening 111
Direction is mobile simultaneously to extract urine, wherein 11 inner wall of shell of spool 12 and switch valve 10 separately and forms the first gap, at this time
Urine capture system 20 is in sampling state, and urine passes sequentially through the second opening 112, the first gap and the first 111 shapes of opening
At the first half-duplex channel, to realize the acquisition of urine specimen；And/or it when acquisition device 22 receives clear instruction, adopts
Acquisition means 22 are used to that spool 12 to be pushed to move along the direction far from the first opening 111 and inject cleaning liquid, wherein spool 12
Separately and the second gap is formed with 11 inner wall of shell of switch valve 10, urine capture system 20 is in cleaning state at this time, clearly
Wash liq passes sequentially through the second half-duplex channel that the first opening 111, the second gap and the second opening 112 are formed, to realize
To the cleaning and sterilization of urine capture system 20, last residual urine is cleaned, avoids the last urine specimen acquired under
The pollution effect of one acquisition, and then the accuracy of urine detection is improved, and the urine capture system can also be reused
System 20, reduces maintenance cost.
As shown in fig. 6, the third aspect of the utility model provides a kind of closestool 30, including closestool body 31 and second
The urine capture system 20 of any embodiment in aspect.
Closestool 30 provided by the utility model, the switch valve 10 of urine capture system 20 are normally closed type switch valve, can be to prevent
Only extraneous bacterium or dust granule access switch valve 10 to reduce the pollution to urine capture, and then improve urine inspection
The accuracy of survey.
Please continue to refer to shown in Fig. 6, in a specific embodiment, closestool body 31 includes the urinal 311 of connection
With closet stall 312, in which: the bottom of closet stall 312 is connected to blow-off line, and the water sealing cover in closet stall 312 is lower than urine
