Description

Technical Field

[0001] The invention relates to the technical field of knee joint restraint belts, in particular to a timeable knee joint restraint belt. Background Art

[0002] Knee restraint refers to a medical device that can provide protection and support for the patient's knee joint. Knee restraint is often used during the patient's postoperative recovery period. By limiting excessive movement of the knee joint, it can reduce pain caused by movement, and by reducing unnecessary movement, it can promote wound healing and tissue repair, thereby enabling patients to recover faster.

[0003] However, the existing knee restraints are usually of one-piece design, which makes it impossible to adjust the angle of the knee restraints, so that patients cannot adjust the knee restraints to a relatively comfortable angle, affecting the comfort of patients while wearing the knee restraints. For this reason, we propose a timeable knee restraint. Summary of the invention

[0004] The object of the present invention is to provide a timeable knee joint restraint belt to solve the problems raised in the above background technology.

[0005] In order to solve the above technical problems, the present invention is achieved through the following technical solutions:

[0007] Furthermore, the top and bottom of the knee joint restraint component are both arranged on a winding component, and the winding component includes four rollers, and the four rollers are respectively arranged on the left and right sides of the knee joint restraint component, and the four rollers are divided into two groups of upper and lower transmission components, and each group of the transmission components includes two rollers, and the two rollers of each group of the transmission components are mirror-arranged with the knee joint restraint component as the center, and the outer surface of the roller on the left side is wound with a limiting rope, and the left side of the limiting rope is fixedly connected to the outer surface of the roller on the left side, and the right side of the limiting rope is wound and connected to the roller on the right side, and the right side of the limiting rope is fixedly connected to the outer surface of the roller on the right side. By setting the roller, the roller can be rotated to wind the limiting rope onto the outer surface of the roller, so that the right side of the knee joint restraint component can be tightened toward the left side, and the patient's leg can be wrapped in the center of the inside of the knee joint restraint component.

[0008] Furthermore, the knee joint restraint assembly includes an upper knee joint restraint belt, a lower knee joint restraint belt is arranged below the upper knee joint restraint belt, and a connecting piece 1 is fixedly connected to the center of the bottom of the left and right sides of the upper knee joint restraint belt, and the two connecting pieces 1 are horizontally mirrored with the upper knee joint restraint belt as the center, and the centers of the bottom of the left and right sides of the lower knee joint restraint belt are fixedly connected to the connecting piece 2, and the two connecting pieces 2 are horizontally mirrored with the lower knee joint restraint belt as the center, and the bottom of the two connecting pieces 1 on the side close to each other is rotatably connected to the top of the side away from each other. By arranging the connecting piece 2, the part of the connecting piece 2 that passes through the connecting piece 1 can rotate on the inner surface of the connecting piece 1, and by arranging the connecting piece 1 and the connecting piece 2, the connecting piece 1 and the connecting piece 2 can drive the upper knee joint restraint belt and the lower knee joint restraint belt to rotate together when rotating.

[0009] Furthermore, the sides of the two connecting members one that are away from each other are fixedly connected to the centers of the sides of the two pin shafts that are close to each other, the sides of the two connecting members one that are away from each other are fixedly connected to the sides of the two adjustment component housings that are close to each other, and the sides of the two ratchet gears that are close to each other are fixedly connected to connecting member two.

[0010] Furthermore, the two ratchet gears are mirror-imaged with the upper knee joint restraint belt as the center, a circular notch is opened at the center of the side away from each other of the two ratchet gears, and a cylindrical protrusion is fixedly connected at the center of the bottom of the inner surface of the side close to each other of the two adjustment component shells, and the two adjustment component shells are plugged into the circular notch of the ratchet gear through the cylindrical protrusion. By setting the cylindrical protrusion of the adjustment component shell and the circular notch of the ratchet gear, the adjustment component shell can limit the ratchet gear by inserting the cylindrical protrusion into the circular notch of the ratchet gear, thereby preventing the ratchet gear from being displaced, thereby ensuring that the equipment adjustment component can operate stably.

[0011] Furthermore, the winding assembly includes two winding assembly shells, and the two winding assembly shells are both arranged on the left side of the knee joint restraint assembly. The two winding assembly shells are arranged in a horizontal array with the knee joint restraint assembly as the center, and the two winding assembly shells are both mounted on the outer side of the roller located on the left side. By setting the winding assembly shell, the winding assembly shell can limit the limiting rope mounted on the outer surface of the roller when the roller is wound, thereby preventing the limiting rope from accidentally slipping from the outer surface of the roller, thereby ensuring the stability of the operation of the winding assembly.

[0012] Furthermore, a motor is fixedly connected to the center of the left side of the two winding assembly shells, the left side of the roller on the left side penetrates the outer surface of the winding assembly shell and extends outward, the outer surface of the left side of the roller on the left side is rotatably connected to the inner surface of the winding assembly shell at the penetration point, the output end of the right side of the motor is at the same horizontal height as the left side of the roller on the left side, the output end of the right side of the motor is fixedly connected to the left side of the roller on the left side through a coupling, the right side of the winding assembly shell at the top is fixedly connected to the left side of the top of the upper knee joint restraint belt, and the right side of the winding assembly shell at the bottom is fixedly connected to the left side of the bottom of the lower knee joint restraint belt. By setting up the motor, the staff can adjust the rotation of the roller through the motor, and then adjust the limit rope.

By providing the ratchet pawl and the ratchet gear, the patient can adjust the angle of the knee joint restraint component through the cooperation of the ratchet pawl and the ratchet gear during rotation, thereby improving the patient's comfort in wearing the knee joint restraint component.

[0017] (2) The present invention provides a winding component, specifically, by rotating the left roller counterclockwise, the roller located on the rear side will drive the left side of the limiting rope fixedly connected to it to rotate through the outer surface, and the roller will also reel in the limiting rope by rotating, and finally tighten the left and right sides of the knee joint restraint component toward the center. In this way, the retraction of the roller can be controlled by rotating the left roller, and the device can be installed on the patient's leg, or the device can be removed from the patient's leg.

[0018] (3) The present invention provides a knee joint restraint assembly, specifically, when the two connecting members 2 rotate, they will rotate through the center of the top and the center of the bottom of the two connecting members 1 of the upper knee joint restraint belt, and the two connecting members 1 will also drive the lower knee joint restraint belt fixedly connected at the center to rotate during the rotation process, so that the lower knee joint restraint belt and connecting member 1 can rotate synchronously.
