Description

Technical Field

[0001] The invention relates to the technical field of medical devices, and in particular to a device for facilitating winding of a blood-removing belt. Background Art

[0002] The blood-removing belt is made of a rubber sheet with good elasticity. The length can be cut according to needs and can be sterilized by gas fumigation or boiling before use.

[0003] When in use, disinfect the patient's affected limb, raise the affected limb above the level of the heart for a moment, and then use one end of the exsanguination belt to tighten the exsanguination belt from the end of the limb to the proximal end. No soft tissue is allowed to be caught between each circle. Until it is wrapped around the base of the limb, the blood in the soft tissue of the operated limb can be expelled from the limb. When wrapping the last circle, first pad the local skin with sterile gauze, and then wrap another exsanguination belt around it and tie a knot to avoid soft tissue damage. Finally, loosen the exsanguination belt from the proximal end circle by circle; if there is a pneumatic tourniquet, it can be wrapped around the last circle of the exsanguination belt, and the air bag can be inflated to about 300mmhg, and the air bag can be inflated to about 150mmhg for children. Keep the pressure constant, and inform the anesthesiologist to record the start time of the exsanguination belt. The inflation time should not exceed 60min. If the operation is proper, the limb will be pale after exsanguination, the peripheral artery will have no pulsation, and no blood will flow out when the skin is incised.

[0004] During the process of wrapping the blood-removing belt, one doctor is required to lift the patient's limb while another doctor wraps it, or one doctor first fixes the patient's limb on a bracket and then wraps it. The wrapping process requires both hands to move back and forth alternately, and the force applied during the wrapping will be uneven, and the force value will fluctuate too much or too little, causing the blood-removing belt to slip easily during the wrapping process, resulting in low winding efficiency and high manpower and time costs. The force applied after wrapping is controlled by the doctor, and there is no guarantee that it is within the appropriate range every time. If the operation is improper, it needs to be re-wrapped, which is troublesome. More blood-removing belts are needed during wrapping. Although some of them can be reused, they need to be disinfected. After disinfection, they need to be manually rolled into a roll, which is time-consuming and labor-intensive. Blood-removing belts are mostly simply piled up when stored, and their hygiene cannot be guaranteed, so they need to be disinfected before each use. Summary of the invention

[0031] The rotating rod 6 is removed from the material bin, the rolled blood-driving belt is put into the material bin, and the blood-driving belt is pulled out and sent to the feeding port. The motor 11 is started to drive the gear mechanism to operate. The gear mechanism drives the transmission mechanism to send the blood-driving belt to the discharging port. At the same time, the clamp 8 extends out of the discharging port, and the blood-driving belt is passed around the patient's limb and installed on the clamp 8. The motor 11 is started again to drive the gear mechanism to reverse. At the same time, the clamp 8 moves back to the initial position. At this time, the blood-driving belt is tightened under the action of the rotating rod 6. The tension sensor on the clamp 8 detects the real-time tension of the blood-driving belt. When the tension reaches the preset value, the tension sensor transmits the signal to the controller 5. The controller 5 controls the fixator 10 and the shear 9 to start. The fixator 10 fixes the upper and lower sections of the blood-driving belt together through the fixing nails. Then the heating wire in the shear 9 melts the blood-driving belt, and the clamp 8 loosens the blood-driving belt to complete the binding of the blood-driving belt.
