Description

Catheter nursing device for oncology vein treatment Technical Field The invention relates to the technical field of medical equipment, in particular to a catheter nursing device for oncology vein treatment. Background The PICC provides a convenient, safe and effective long-term vein channel for a patient, is widely applied to clinical treatment and is used for central vein catheterization through peripheral vein puncture, the catheter is used for puncturing from veins of peripheral arms, puncture point dressing needs to be replaced and disinfected every day after puncturing, and the catheter needs to be prevented from being pulled out when puncture point dressing is replaced. The existing catheter nursing device for oncology vein treatment has no fixed mechanism, when the arm of a patient is nursing, the problem that the arm of the patient is swayed or the catheter is pulled out or shifted due to improper operation of medical staff is easily caused, and the safety and the efficiency of nursing are reduced. For this purpose, we propose a catheter care device for oncology intravenous therapy. Disclosure of Invention The invention mainly solves the technical problems in the prior art and provides a catheter nursing device for oncology vein treatment. In order to achieve the above purpose, the technical scheme is that the catheter care device for oncology vein treatment comprises a mounting seat, an arm clamping and fixing mechanism is arranged on the outer wall of the mounting seat, the arm clamping and fixing mechanism comprises a servo motor, the front face of the servo motor is fixedly connected with the upper end of the back face of the arm clamping and fixing mechanism, the output end of the servo motor movably penetrates through the front face of the mounting seat, a screw rod is fixedly arranged at the output end of the servo motor, a mounting frame is movably arranged at the front face of the screw rod, the back face of the mounting frame is fixedly connected with the front face of the mounting seat, a connecting frame is fixedly arranged at the middle end of the front face of the mounting frame, a limit guide rod is fixedly arranged at the front end of the inner wall of the mounting frame, and the back face of the limit guide rod is fixedly connected with the front face of the mounting seat. Preferably, the outer wall thread of the screw rod is connected with a moving block, and the inner wall of the moving block is movably connected with the outer wall of the limit guide rod. Preferably, the upper end of the outer wall of the moving block is movably provided with a first connecting rod through a rotating shaft, and one end of the first connecting rod, which is far away from the moving block, is movably provided with a first L-shaped connecting rod through the rotating shaft. Preferably, the middle end of the inner wall of the first L-shaped connecting rod is movably connected with the upper end of the outer wall of the connecting frame through a rotating shaft. Preferably, a first clamping arc plate is fixedly arranged on the front surface of the first L-shaped connecting rod. Preferably, the lower end of the outer wall of the moving block is movably provided with a second connecting rod through a rotating shaft. Preferably, one end of the second connecting rod, which is far away from the moving block, is movably provided with a second L-shaped connecting rod through a rotating shaft. Preferably, the middle end of the inner wall of the second L-shaped connecting rod is movably connected with the lower end of the outer wall of the connecting frame through a rotating shaft.
