Traction device for occluding cuff device

Abstract

The invention relates to a traction device for an occluding cuff device. The traction device comprises a bottom plate and an occluding cuff. A motor is installed on the bottom plate. The output shaft end of the motor is provided with a rotating belt wheel. A slide rail positioning plate is installed in the middle of the bottom plate and provided with a first slide rail. A first fine adjusting slider and a second fine adjusting slider are installed in the first slide rail. A left supporting plate and a right supporting plate are installed on the bottom plate. A left guide wheel is installed on the left portion of the left supporting plate. A second slide rail is installed in the middle of the left supporting plate. A second slider is installed in the second slide rail. A right guide wheel is installed on the right portion of the right supporting plate. A third slide rail is installed in the middle of the right supporting plate. A third slider is installed in the third slide rail. The upper end of the third slider is fixedly connected with the right end of the occluding cuff. The two ends of the first fine adjusting slider, the two ends of the second fine adjusting slider, the two ends of the second slider and the two ends of the third slider are each provided with a fixed buckle plate. The left end of the first fine adjusting slider, the left end of the second slider, the right end of the second fine adjusting slider and the right end of the third slider are connected through a working belt. The right end of the second slider and the left end of the third slider are connected with the rotating belt wheel through a working belt.

Description

technical field [0001] The present invention relates to a pulling device for a cuff device. Background technique [0002] Before venipuncture, medical personnel usually tie an elastic cuff on the upper part of the patient's puncture to slow down the return of venous blood, so that the local blood vessels can be filled to facilitate successful puncture, and at the same time, it is convenient to draw enough venous blood. The current tourniquet is generally cut from an ordinary elastic silicone tube. Because the diameter of the silicone tube is small, the force-bearing area at the binding site is small, and the pressure on the body tissue is relatively large. Feel pain of varying degrees. Because the pressure is difficult to control during the use of the existing cuff, and in special patient groups such as edema patients or patients who need to puncture the lower limbs, it often causes damage to the patient and leads to skin damage. In order to solve the above problems, an au...

AI Technical Summary

Problems solved by technology

Due to the difficulty in controlling the pressure during the use of the existing cuff, and in special patient populations such as patients with edema or patients who need to puncture the lower limbs, it often causes damage to the patient and leads to skin damage

In order to solve the above problems, an automatic cuff device was invented. The pulling device in the existing automatic cuff device is usually only one-way to realize the contraction and extension of the cuff, without fine-tuning function, and at the same time due to the pressure The control is not in place, and medical staff are required to manually disassemble it, resulting in low work efficiency. Therefore, it is urgent to invent a pulling device for cuff equipment that is easy to disassemble, has fine-tuning function, and has high work efficiency.
