Description

Midstream urine collecting device

Technical Field

The utility model belongs to the technical field of medical treatment auxiliary appliances, concretely relates to middle section urine collection device.

Background

Urine tests are a common test method in clinical disease tests, and in the urine tests, a tester needs to take midcourse urine. According to the order that urine passes through the urethral orifice when urinating, divide into anterior segment, middle section and back end with the urine, middle section urine is exactly that the part urine that is in the centre during the urination (continuous urination does not break), and anterior segment urine can wash the urethra, takes away the bacterium around the urethra or urethral orifice, therefore leaves middle section urine and can reduce the influence of bacterium etc. to detecting the structure. However, most of the existing urine collecting devices are ordinary disposable urine cups, the urine collecting devices are difficult to accurately control to leave and take midcourse urine, the examination result is influenced, and the urine is easy to drip, leak and spill in the sampling and transferring processes, so that the urine collecting devices are neither sanitary nor convenient.

The invention patent with publication number CN106092660A discloses an automatic closing type midstream urine collector, which comprises a urine cup with an opening at the upper end and a conduit communicated with the urine cup, wherein the bottom of the urine cup is provided with a waste liquid inlet. The urine that flows in earlier stage at first gets into the waste liquid chamber, and the waste liquid chamber is full of the back, and the urine just flows through the pipe, accomplishes the collection of middle section urine. However, in the technical scheme, the waste liquid collecting cavity is not provided with a reliable backflow prevention device, and the catheter is not easy to control the urine to flow out and stop. The invention patent with publication number CN107290187A adds a sealing component on the catheter for draining urine, which is used for controlling the discharge of urine and is cleaner and more sanitary. But its seal assembly sets up the one end of keeping away from the collection body at the pipe, in difficult to avoid anterior segment urine to get into the pipe, introduces detection error easily. The invention patent publication No. CN107449640A discloses a liquid segment collector, which is relatively simple in structure, but the discharge of the first urine is based on the flow rate of the urine discharged by the user and the size of the through hole on the stopper plate of the urine discharge tube, if the flow rate of the urine discharged by the user is too low, the liquid level of the urine will not rise to flow into the test tube for collection, otherwise, when the flow rate of the urine discharged by the user is too high, the liquid level of the urine will rise rapidly to enter the test tube, the first urine will not enter the test tube, and it can not be seen that the collector can be operated to ensure the accurate collection of the first urine.
