This basic scheme is through setting up the piston rod in the cup, and the piston rod upwards floats along with urine increases in the cup, when urine was collected and is reached set amount, the piston rod will advance the urine mouth and seal completely, realizes automatic ration sample.

Further, a floating cover is arranged in the cup body, and a liquid leakage hole is formed in the floating cover; the floating cover density is less than the urine density; the piston rod is arranged on the floating cover, the floating cover is in sliding fit with the cup body, and the floating cup has the advantages that: the amount of urine is related to the movement of the piston rod through the floating cover, and the urine inlet is automatically closed after the urine reaches the amount; the leakage port is convenient for urine to flow into the cup body.

Furthermore, the upper end of the piston rod and the lower end of the urine inlet are both conical, the sizes of the cones are matched, and the conical surfaces are favorable for sealing the urine inlet.

Further, still be equipped with a step in the cup, step top, beneficial effect are located to the lid that floats: the length of the piston rod is shortened through the step surface.

Furthermore, the cup body is also provided with scale marks, and whether the sampling quantity reaches the standard or not is confirmed through the scale marks.

The vacuum cup further comprises a negative pressure drainage ball, a negative pressure port is formed in the cup cover, and the negative pressure port is communicated with the inner cavity of the specimen cup; negative pressure drainage ball is connected with the negative pressure mouth, beneficial effect: through negative pressure drainage ball, provide negative pressure, introduce the urine from the ureter in the cup.

The beneficial effects of the utility model reside in that: the urine is introduced into the cup body from the ureter through the negative pressure drainage ball, the piston rod which floats upwards along with the increase of the urine amount is arranged in the cup body, the sampling amount is controlled through the piston rod, the automatic control of the sampling amount is realized, the problem of urine overflow is avoided, and the cleanness and the sanitation of the sampling process are guaranteed.

Additional advantages, objects, and features of the invention will be set forth in part in the description which follows and in part will become apparent to those having ordinary skill in the art upon examination of the following or may be learned from practice of the invention. The objectives and other advantages of the invention may be realized and attained by the means of the instrumentalities and/or combinations particularly pointed out in the appended claims.
