The utility model discloses a
urine collection bag which comprises a
urine collection bag body and particularly relates to the technical field of
medical instruments, the top of the
urine collection bag body is fixedly connected with a liquid
inlet valve, the top of the liquid
inlet valve is fixedly connected with a
catheter, one end of the
catheter is fixedly connected with a connecting mechanism, the top of the
urine collection bag body is fixedly connected with a liquid outlet valve, and the top of the
urine collection bag body is fixedly connected with the connecting mechanism. The top of the liquid outlet valve is fixedly connected with a liquid outlet
pipe, and the liquid
inlet valve and the liquid outlet valve are consistent in structure. According to the
urine collection bag, whether liquid can enter the urine collection bag body or not is controlled through the arranged liquid inlet valve, whether the liquid in the urine collection bag body can be discharged through the liquid outlet
pipe or not is controlled through the liquid outlet valve, when sampling is needed, only the liquid inlet valve needs to be closed, the liquid outlet valve needs to be opened, then the urine collection bag body is squeezed, and urine can be discharged through the liquid outlet valve and the liquid outlet
pipe; according to the equipment, liquid is discharged in a manual
extrusion mode, liquid can be accurately taken only by controlling the
extrusion force, and the problem that in the prior art, liquid taking is not accurate is solved.
