Sealed connection is formd, the gas in test tube can only be discharged from vent connection and exhaust passage, due to vent connection and fixation
It is formed and is tightly connected between head, when the urine in test tube touches the insertion end of vent connection, urine can block up vent connection
Firmly, gas can not be discharged from vent connection and exhaust passage in such test tube, and the air pressure in test tube becomes larger to make in funnel
Urine cannot enter back into test tube, this makes it possible to carry out quantitative collection to urine, can preferably control and adopt urine volume.
Vent connection is socketed in the fixing head of exhaust portion, can be lengthened in this way to the length of exhaust portion, and pass through
The vent connection of socket quantitative length preferably carries out quantitative collection, and urine volume is adopted in preferably control.Urine can be quantitatively adopted a set of
The vent connection of mating multiple and different quantitative lengths in device selects suitable vent connection according to the needs of urine detection, then
Vent connection is socketed in exhaust portion, it is easy to use；The quantity of funnel mold can also be reduced in this way, and reduction is produced into
This.Exhaust portion length can be than drain minister, can also be isometric or shorter than drain portion with drain portion, due to the other row of being additionally arranged
Gas adapter tube, the length of such exhaust portion can be shortened suitably, avoid the length of exhaust portion is too long from causing forming defect, avoid being vented
The hole influence urine sampler that leaks air in portion is accurately controlled to urine volume is adopted.
In above-mentioned quantitative urine sampler, gap one, the vent connection are provided between the fixing head and drain portion
It enters in gap one.
The setting in gap one guarantees the length long enough that vent connection is sleeved in fixing head, to make vent connection and consolidate
The sealing effect determined between head is good, prevents the junction of the two from leaking air, so that controlling urine sampler preferably adopts urine volume.
In above-mentioned quantitative urine sampler, gap two, the vent connection are provided between the fixing head and interconnecting piece
It enters in gap two.
The setting in gap two is further ensured that the length long enough that vent connection is sleeved in fixing head, so that exhaust be made to connect
Sealing effect between pipe and fixing head is good, prevents the junction of the two from leaking air, adopts so that urine sampler be made preferably to control
Urine volume.Vent connection enters in gap two, protects the socket end of vent connection in interconnecting piece, internal plug can be prevented to be caught in
To between the socket end and interconnecting piece of vent connection, internal plug takes vent connection out of from fixing head when preventing test tube from extracting.
In above-mentioned quantitative urine sampler, the fixing head is tapered.
On the one hand it can be convenient vent connection and be nested into fixing head, on the other hand can make fixing head and vent connection
Fixed effect and sealing effect are good, so that controlling urine sampler preferably adopts urine volume.
In above-mentioned quantitative urine sampler, the vent connection is removably attached in fixing head.Pass through replacement in this way
Vent connection can adjust and adopt urine volume, no replacement is required entire urine sampler, keep urine sampler easy to use, and can preferably control
Adopt urine volume.
In above-mentioned quantitative urine sampler, the vent connection is made of polyvinyl chloride.
Polyvinyl chloride abbreviation PVC, has elasticity well, the fixed effect that forms vent connection in fixing head and close
It is good to seal effect, so that controlling urine sampler preferably adopts urine volume.
In above-mentioned quantitative urine sampler, the interconnecting piece is arranged in the following side of funnel, the drain portion, interconnecting piece and
For exhaust portion to the bottom angled of funnel, the drain portion is located at the lower section of exhaust portion.
Picker is held on test tube when acquiring urine, and by the opening up of funnel, urine enters from the opening of funnel
In to funnel and in the congregate of funnel.After the following side of funnel is arranged in drain portion and interconnecting piece, connected by interconnecting piece
Test tube be also located in the following side of funnel, urine splashes picker's when can reduce acquisition while facilitating picker to hold
On hand.And the following side that opening funnel is arranged in interconnecting piece and makes drain portion, interconnecting piece and exhaust portion close to the bottom of funnel
To the bottom angled of funnel, urine can be made successfully to be flowed into test tube from the bottom of funnel under self gravitation effect in this way
In, and do not have to tilt in funnel, to prevent urine during tilting funnel in funnel from leaking.And it will row
The lower section of exhaust portion is arranged in liquid portion, can prevent the urine flowed out from drain portion from flowing to exhaust along the lateral surface of vent connection
Liquid film is formed at the insertion end port of adapter tube to block vent connection, is prevented exhaust passage from closing influence in advance and is adopted urine volume, thus
Preferably urine volume is adopted in control.
In above-mentioned quantitative urine sampler, there is gap three between the interconnecting piece and drain portion.
At the end of urine capture, need to remove test tube from funnel.Needing when test tube is removed from funnel will even
Connection relationship between socket part and internal plug releases, and the gap three being arranged between interconnecting piece and drain portion can make interconnecting piece from interior
It can be shunk slightly to drain portion when being detached from plug, to facilitate removing for test tube.The setting in gap three can also be thinned simultaneously
The wall thickness that generates when being integrally formed between interconnecting piece and drain portion, when preventing connection shaping interconnecting piece caused by contraction distortion with
Leakproofness between internal plug is deteriorated, and influences the controllability for adopting urine volume.
