Medical urine drainage device facilitating sampling

The invention discloses a medical urine drainage device facilitating sampling. The medical urine drainage device facilitating sampling comprises a drainage tube, a urine collection bag, a sampling bag and a distribution control valve. Three channels communicated with one another are formed in the distribution control valve and comprise the drainage channel, the urine collection channel and the sampling channel respectively, one end of the drainage channel is communicated with the drainage tube, the outlet end of the urine collection channel is connected with the urine collection bag, and the outlet end of the sampling channel is connected with the sampling bag. The urine collection channel and the sampling channel are arranged in parallel, the distribution control valve is further provided with a blind hole intersecting with the urine collection channel and the sampling channel at the same time, a control column shorter than the blind hole is installed in the blind hole in a sleeved mode, a sliding rod used for making the control column slide along the blind hole is arranged on the side face of the control column, one end of the sliding rod is fixed to the control column, and the other end of the sliding rod stretches out of the distribution control valve. The medical urine drainage device facilitating sampling overcomes the defect that sampling cannot be conducted at any time through a traditional urine drainage device, and the medical urine drainage device facilitating sampling facilitates nursing and sampling detection conducted by medical workers and effectively improves the working efficiency of the medical workers.
