Throughout the specification and claims, unless explicitly stated otherwise, the term "comprise" or variations thereof such as "comprises" or "comprising", etc. will be understood to include the stated element or component without excluding other elements or components.
Fig. 1 shows a schematic structure of a precision urine meter according to a preferred embodiment of the present invention, which includes a measuring cylinder 1, an outlet connection pipe 4, an anti-reflux inner plug 5, and an inlet connection pipe 8, and with reference to fig. 1, a capacity scale is provided on a wall surface of the measuring cylinder 1 for indicating the amount of urine stored in the measuring cylinder 1. The measuring cylinder 1 can be in a conical cup shape with a large upper part and a small lower part, and the measuring cylinder 1 can be provided with various specifications for selection according to the size of the capacity, so that the clinical selection according to the needs of the illness state is facilitated. For example, the measuring cylinder 1 is set to be 50ml, 100ml, 200ml, 250ml and other different specifications according to the capacity, and for convenient and accurate reading, the minimum scale of the measuring cylinder 1 of 50ml and 100ml is 2ml, and the minimum scale of the measuring cylinder 1 of 200ml and 250ml is 5ml. Preferably, the material of the measuring cylinder 1 is polyvinyl chloride or high-pressure polyethylene. The metering cylinder 1 can be reused, and can be replaced for 1 time or used once in 7 days according to the requirements of an article disinfection and isolation system. The lower end of the metering cylinder 1 is provided with a metering cylinder outlet 3, and the upper end of the metering cylinder 1 is provided with a metering cylinder inlet 2.
With continued reference to fig. 1, one end of the outlet connection pipe 4 is connected with the outlet 3 of the metering cylinder, and the other end of the outlet connection pipe 4 is used for being connected with the drainage bag 7, an outlet switch 10 is arranged on the outlet connection pipe 4, when urine in the metering cylinder 1 needs to be discharged outwards, the outlet switch 10 is opened, the urine flows into the drainage bag 7, and then the urine is discharged intensively by the drainage bag 7.
With continued reference to fig. 1, the anti-backflow inner plug 5 is fixedly sleeved in the metering cylinder inlet 2, the upper part of the anti-backflow inner plug 5 is in sealing fit with the inner wall of the metering cylinder inlet 2, and a gap is reserved between the lower part of the anti-backflow inner plug 5 and the inner wall of the metering cylinder inlet 2. The anti-backflow inner plug 5 is provided with an inner hole with an opening at the upper end, the lower part of the side wall of the anti-backflow inner plug 5 is provided with a plurality of side holes 6 communicated with the inner hole, and urine entering the inner hole flows downwards into the metering cylinder 1 through the side holes and a gap between the lower part of the anti-backflow inner plug 5 and the inner wall of the metering cylinder inlet 2. Preferably, the side hole 6 is a circular hole with a diameter of 2-3 mm, preferably a circular hole with a diameter of 2 mm. One end of the inlet connecting pipe 8 is connected with the inner hole, the other end of the inlet connecting pipe 8 is connected with the catheter 9, and an inlet switch 13 is arranged on the inlet connecting pipe 8. By opening the inlet switch 13, the urine catheter 9 can guide urine discharged from a patient into the inner hole of the anti-reflux inner plug 5, and the urine finally flows into the metering cylinder 1. And the inner hole of the anti-backflow inner plug 5 is communicated with the metering cylinder 1 through the side hole, so that the urine can be effectively prevented from directly flowing backwards.
