Description

Technical Field

[0001] The utility model relates to the field of postoperative calf support and fixation, in particular to a calf support and fixation device. Background Art

[0002] After posterior cruciate ligament reconstruction surgery, patients with posterior cruciate ligament injury of the knee need an external fixator to replace the function of the normal posterior cruciate ligament to limit the posterior displacement of the tibia in the early stage of postoperative rehabilitation in order to protect the stability of the newly repaired ligament and bone tunnel rivet. An additional fixator is needed on the upper part of the calf of the operated limb to lift the tibia forward to prevent the tibia from moving backward. Existing calf support fixation devices, such as towels, are not easy to fix and are easy to loosen. Looseness is not easy to detect immediately, which increases the risk of ligament re-injury.

[0003] How to invent a calf support fixation device to improve these problems has become an urgent problem to be solved by those skilled in the art. Utility Model Content

[0004] In order to remedy the above deficiencies, the utility model provides a calf support fixing device, aiming to improve the problem that the existing calf support fixing device is difficult to fix and easy to loosen, and it is difficult to immediately detect when loose, which increases the risk of ligament re-injury.

[0005] To achieve one of the above-mentioned purposes of the invention, the utility model provides a calf support and fixation device, including a ligament protection mechanism and a padding mechanism, wherein the ligament protection mechanism includes a binding member, and the binding member is arranged in two layers.

[0006] The raising mechanism includes a breathable part and an inflatable part. The raising mechanism is arranged inside the binding part. The breathable part includes an air intake pipe, an annular connecting pipe, an axial connecting pipe and a leakage ball. The air intake pipe is connected to the annular connecting pipe. There are multiple axial connecting pipes and the leakage ball. The multiple axial connecting pipes are arranged in an annular array. The axial connecting pipe is connected to the annular connecting pipe. A through hole is opened in the leakage ball. The through hole at the bottom of the leakage ball is connected to the axial connecting pipe. The through hole of the leakage ball is higher than the inner circle of the binding part. The air intake pipe is connected to the inflatable part.

[0007] In one embodiment of the utility model, the binding piece includes an inflatable belt, a fluff belt, and a barb belt. The bottom of the fluff belt is fixedly installed on one end of the inflatable belt, one end of the barb belt is fixedly installed on the other end of the inflatable belt, and the other end of the barb belt is adhered to the fluff belt.

[0008] In one embodiment of the utility model, a stabilizing plate is installed outside the inflatable belt, two stabilizing plates are arranged symmetrically in an annular shape, and the stabilizing plates are arranged horizontally.

[0009] In an embodiment of the utility model, a barrier belt is arranged in the middle of the inflatable belt, and a through hole is arranged in the middle of the barrier belt.

[0010] In an embodiment of the utility model, the internal through hole of the leakage ball is T-shaped, and the leakage balls are evenly distributed in the axial connecting tube.

[0011] In one embodiment of the utility model, the inflatable member includes a first air outlet pipe and a second air outlet pipe of the inflatable pipe. The inflatable pipe, the first air outlet pipe, the second air outlet pipe and the air inlet pipe are cross-connected. The second air outlet pipe seals the through hole in the middle of the barrier strip.

[0012] In an embodiment of the utility model, the inflatable member further comprises a solenoid valve, and three solenoid valves are provided. The three solenoid valves are arranged at the first air outlet pipe, the second air outlet pipe and one end of the air inlet pipe close to the inflatable pipe.

[0013] In an embodiment of the present invention, the leaking ball is a rubber ball.

[0014] In one embodiment of the utility model, a pressure sensor, a battery, a single-chip microcomputer and a buzzer are arranged inside the strap part. The battery is used to power the pressure sensor, the single-chip microcomputer and the buzzer. The pressure sensor is electrically connected to the single-chip microcomputer and the buzzer.

[0015] In one embodiment of the utility model, the single chip microcomputer is provided with a data transmission module, and the single chip microcomputer is connected to the terminal signal through the data transmission module.

[0016] The beneficial effects of the utility model are as follows: the utility model provides a calf support and fixing device obtained by the above design. When in use, the leg with injured posterior cruciate ligament is put into the binding piece and is tied tightly by the fluff belt and the barbed belt, so that the binding piece is close to the leg, and then the air inlet pipe is inflated, and the gas enters the inflatable belt through the first air outlet pipe and the second air outlet pipe. The air inlet pipe is inflated to support the leg so that the leg is not easily suspended in the air, and the gas leaks out from the T-shaped hole of the leaking ball through the air inlet pipe. The inflatable belt is easy to sweat and be blocked when tightening the leg for a long time. The gas is blown out from the leaking ball through the air inlet pipe for ventilation and heat dissipation. The stabilizing plate is used to limit the leg to prevent the leg from tilting left and right, which has a stabilizing effect on the leg. The solenoid valve is used to open and close the air inlet to adjust the upper and lower air pressure of the inflatable belt and control whether the leaking ball is blown. The pressure sensor confirms whether the gas in the inflatable belt meets the needs by sensing the pressure. The data of the pressure sensor and the single-chip microcomputer are connected with an external mobile phone or computer through a data transmission module to facilitate remote observation of the patient's leg status. The problem that the existing calf support fixing device is difficult to fix and easy to loosen is reduced, and the loosening is difficult to detect immediately, which increases the risk of ligament re-injury. The condition of the patient's leg can be monitored remotely to reduce the probability of secondary leg injury. BRIEF DESCRIPTION OF THE DRAWINGS
