A detachable bedside drainage tube fixing device with a slide rail includes a linear slide rail and a triangular sliding frame. The linear slide rail is fixedly installed on the side of the bed. The triangular sliding frame has a triangular sliding groove. A fixed bearing is installed at one corner of the triangular sliding frame, and a rotating shaft is installed in the middle of the fixed bearing. The end of the rotating shaft passes through the triangular sliding frame and is fitted with a sliding component, which is movably installed within the linear slide rail. A sliding bearing is slidably connected within the triangular sliding groove, and a positioning ball is installed within the sliding bearing. The surface of the positioning ball has a bowl-shaped notch. This invention overcomes the shortcomings of the prior art, effectively avoiding needlestick injuries caused by using sharp instruments for fixing, and allowing for adaptive adjustment of the drainage tube's fixing position, thereby effectively preventing accidental tube removal or bleeding due to traction on the drainage tube.

The utility model discloses an improved catheter, which belongs to the technical field of medical instruments and comprises a catheter body, a three-way tube urine drainage tube and a pressure relief component, the urine drainage tube is connected to a discharge end of the catheter body, the catheter body is provided with a three-way tube, and the pressure relief component is arranged between the three-way tube and the urine drainage tube. The pressure relief assembly comprises a pressure relief valve and a pressure monitoring pipe which are sequentially arranged on the outer wall of the pipe body, and the three-way pipe comprises a main catheterization pipe, a side catheterization pipe and a switching valve. The urethral catheter has the advantages that after the urethral catheter is inserted into the body of a patient, urine of the human body can be drained and discharged, the pipe body is provided with the three-way pipe, the internal pipe of the urethral catheter can be switched through the switching valve, the urethral catheter main pipe is closed, the urethral catheter side pipe is opened, and a specimen or bladder irrigation and external medicine can be reserved from the urethral catheter side pipe. The catheter does not need to be separated, puncture operation with a needle is reduced, puncture injury caused by the needle is avoided, the catheter is provided with the pressure relief valve and the pressure monitoring pipe, and pipeline pressure can be monitored and relieved.
