Matched unidirectional mantle 23 is set in 22 upper chambers of ventilated membrane that block water.13 activity of out sample tube of the urine sampling funnel 1 is nested with
In quantitative 2 intracavitary of counterflow-preventing conduit.
When men's, it is only necessary to penis is inserted to the intracavitary of urine sampling funnel 1 by arc opening 11, urine can also take along urine
The inner wall trickling of sample funnel 1, finally discharges along the out sample tube 13 of 1 bottom of urine sampling funnel, eventually enters into quantitative Anti-backflow
The intracavitary of pipe 2.When lady's, practical standpoint is slightly different with male, it is only necessary to will be leaked with the urine sampling of female perineum form fit
11 ring of arc opening of bucket 1 covers on perineum, and urine can trickle along the inner wall of urine sampling funnel 1, finally be leaked along urine sampling
Struggle against the outlet discharge of 1 bottom, eventually enters into the intracavitary of quantitative counterflow-preventing conduit 2.
After urine enters the intracavitary of quantitative counterflow-preventing conduit 2, the gas of quantitative 2 intracavitary of counterflow-preventing conduit is by quantitatively anti-reverse
The ventilated membrane 22 that blocks water on 2 top of conductance pipe is discharged, so that urine is retained in quantitative 2 intracavitary of counterflow-preventing conduit until blocking water ventilative
Film 22 is submerged.Hereafter, since unidirectional mantle 23 is to the circular sealing function of out sample tube 13,2 intracavitary of counterflow-preventing conduit is quantified
Gas cannot be discharged by the gap of 13 outer wall of unidirectional mantle 23 and out sample tube, meanwhile, the ventilated membrane 22 that blocks water is submerged and can not arrange
Gas, the intracavitary that urine enters quantitative counterflow-preventing conduit 2 stop, extracting out sample tube 13, take urine to terminate.
It is required that the top edge position for the ventilated membrane 4 that blocks water directly accurately determines that out sample tube 13 can be anti-reverse into quantifying
The amount of liquid of 2 intracavitary of conductance pipe, the top edge position for the ventilated membrane 4 that blocks water is higher, and the liquid that can be collected is more, and position is lower,
The liquid that can be collected is fewer.When out sample tube 13 is extracted, since the space that out sample tube 13 occupies diminishes, fluid level declines slightly,
The ventilated membrane 4 that blocks water topmost leaks out fluid level cruelly, but 13 intraluminal liquid of out sample tube continues the fluid level that supplement declines that flows down,
Still stop when flooding and blocking water 4 upper limb of ventilated membrane, still accurate quantitative analysis.
The catheter body lateral wall sets containing mark line, preferably only topmost sets capacity to carve in the ventilated membrane 4 that blocks water
Line and capacitance values are spent, the graduation mark by reading 4 the top of ventilated membrane that blocks water can determine that the quantitative counterflow-preventing conduit 2 of the present invention takes
Liquid measure, the preferred different colours of conduit graduation mark of different liquid-taken amounts, distinguish easy to user and take.

In male in use, the purpose of setting of isocon 14 is the urine when out sample tube 13 inserts quantitative counterflow-preventing conduit 2
It will be stockpiled after filling with quantitative counterflow-preventing conduit 2 in urine sampling funnel 1.When urine exceedes the urine diffluence pass of isocon 14
During 141 level, the urine having more can be discharged from the intracavitary of isocon 14, avoid urine from continuing to stockpile in urine sampling funnel 1,
Even overflowed by the arc opening 11 of urine sampling funnel 1, cause patient's skin of perineum or hold the hand of urine sampling funnel 1
By urine pollution.Meanwhile the urine diffluence pass 141 of isocon 14 is higher than 1 inner surface of urine sampling funnel, it is possible to reduce or avoid
It is expelled directly out when urine is less from the urine diffluence pass 141 of isocon 14, is unfavorable for urine sampling.
Women is in use, as shown in Fig. 2, the angle difference of urine sampling funnel 1, out sample tube 13 and shunting when specifically used
The shift in position of pipe 14, replaces out sample tube 13 and 14 function of isocon.The position of isocon 14 is less than out sample tube 13, undertakes out
Sample pipe 13 discharges urine sample to the function of quantitative counterflow-preventing conduit 2.And 13 position of out sample tube is higher than isocon 14, isocon 14 is undertaken
Discharge the function that excessive urine volume avoids urine from overflowing.In order to make out sample tube 13 more preferably undertake the function of isocon 14, out sample tube 13
Urine filling mouth 131 above 1 inner surface of urine sampling funnel.When it is implemented, urine diffluence pass 141 and urine filling mouth 131 are higher by
Unsuitable excessive, the preferably 0.5cm-1cm of the height of 1 inner surface of urine sampling funnel.
