Detailed Description

The invention will be described in further detail with reference to the following figures and specific embodiments:

the urine sampling device shown in the figure comprises an allantoic bag and a urine bag pipe, wherein the allantoic bag comprises a compression cavity 3 and a liquid pouring port capable of being opened and closed, the liquid pouring port is arranged at the top of the compression cavity 3, the urine bag pipe comprises a liquid inlet pipe 4 and a liquid outlet pipe 6 which are arranged at the bottom of the compression cavity 3, the liquid inlet pipe 4 and the liquid outlet pipe 6 are led out by the same interface at the bottom of the compression cavity 3, a liquid inlet valve 5 is arranged on the liquid inlet pipe 4, and a liquid outlet valve 7 is arranged on the liquid outlet pipe 6. The allantois storage bag comprises a compression cavity and a liquid pouring port capable of being opened and closed, and a pump type structure capable of being manually compressed is formed, when the compression cavity needs to be compressed, the liquid pouring port is opened, air in the compression cavity is discharged, the liquid pouring port is closed, the compression cavity rebounds, so that urine enters the compression cavity, and after sampling is finished, a urine sample is poured out through the liquid pouring port without extracting the sample from a catheter, so that the allantois storage bag is convenient to use, and the privacy of a patient is protected; urine bag pipe includes feed liquor pipe and drain pipe, and feed liquor pipe and drain pipe are drawn out by the same interface in compression chamber bottom, can prevent that anterior segment urine from flowing into the compression chamber via the feed liquor pipe and reentry the drain pipe, influence the accuracy of sample, set up feed liquor valve and drain valve on feed liquor pipe and the drain pipe respectively, and the accuracy of sample is guaranteed in the flow direction of steerable urine.

Preferably, the pouring spout comprises a mouth 10 and a cap 9. The preferred bottle neck is long and thin tubular bottle neck, and the outside is covered with independent bottle lid, bottle neck and bottle lid cooperation, and it is convenient to open and shut, and the bottle lid that opens and shuts when solitary bottle lid can avoid falling the liquid is infected with the urine.

Preferably, a bottleneck 11 is arranged on the outer ring of the bottle mouth 10, a liquid return groove 12 is formed between the bottleneck 11 and the bottle mouth 10, and a liquid return port 13 is formed at the joint of the liquid return groove 12 and the compression cavity 3. Preferably, the liquid return groove is designed to be an inclined plane, the highest end is arranged on the outer side of the sample cup, the lowest end is arranged on the inner side of the sample cup, and the lowest end is provided with a liquid return port leading to the compression cavity. When empting the urine in the storage allantois, the unrestrained urine can be collected to the liquid return tank, and unrestrained urine flows back to the compression chamber through returning the liquid mouth, avoids the urine to cause the pollution, returns the liquid mouth simultaneously and can guarantee that the inside and outside atmospheric pressure of storage allantois is balanced when pouring out the urine sample, is favorable to the urine to pour out.

Preferably, the mouth 10 is a beveled mouth type mouth 10. The bottle mouth of oblique mouth formula design can reduce the unrestrained probability of urine.

Preferably, the bottom of the compression chamber 3 is in the shape of an inverted cone. The compression chamber bottom designs to the back taper, can not get into the compression chamber when the front end urine flows through the compression chamber from the feed liquor pipe, and the guarantee compression chamber does not receive the pollution of anterior segment urine, guarantees the sample quality.
