[0024] Working process
[0025] First, place the traction clip 4 on the part of the patient that needs traction, and ensure that the traction clip 4 is fixed to the bone part of the patient that needs traction. Connect the first hanging ring 9 of the tension sensor 1 to the first connection hole 8 at the rear end of the traction clip 4 to ensure that the sensor can accurately measure the traction force. Insert the flat head pin 11 between both ends of the connecting member 10, and set a pin hole 12 at one end thereof. Insert the split pin 13 into the pin hole 12 to fix the flat head pin 11. Fix the pulley bracket 15 on the hospital bed bracket 19, ensure that the sleeve 16 of the pulley bracket 15 is sleeved on the hospital bed bracket 19, adjust the pulley bracket 15 so that it is inclined at 45° to the horizontal direction, and fixedly connect it to the hospital bed bracket 19 through bolts and nuts via the first through hole 21 and the second through hole 22. Pass the traction rope 5 through the pulley 6. Connect the second hanging ring 14 at the front end of the traction rope 5 to the connecting member 10, and connect the rear end of the traction rope 5 to the weight. The weight is placed in the weight basket 7. Ensure that the weight basket 7 is fixed in an appropriate position so that the traction rope 5 can move smoothly.
[0026] During use, the traction clip 4 is fixed on the patient's limb, and the tension sensor 1 is connected to the weights in the weight basket 7 through the traction rope 5. When the weights drop due to gravity, the traction force is transmitted to the tension sensor 1 through the traction rope 5 and then acts on the patient's limb. The tension sensor 1 measures the magnitude of the traction force in real time. The distance measuring sensor 2 monitors the distance between the weight basket 7 and the horizontal direction to ensure the stability of the traction state. Once the traction force exceeds the set range or the distance of the weight basket 7 is abnormal, the alarm 3 will immediately issue an alarm to prompt the medical staff to take corresponding measures.
[0027] In summary, the utility model can achieve the control and monitoring of the traction force, and has the advantages of simple structure, convenient disassembly and installation.
