[0002] The orthopedic skin traction lifting frame is a device used in the treatment of fractures. It is usually composed of components such as a bracket, a rope or a belt. The rope or belt is fixed to the injured limb, and then the limb is lifted through the bracket to achieve fracture reduction and fixation. This device can help maintain the correct position of the fracture site and promote fracture healing; the orthopedic skin traction lifting frame is often used to treat femoral fractures, recovery after hip replacement surgery, ankle fractures, etc. By applying appropriate traction and lifting force, the fracture site can be stabilized, pain can be relieved, and healing can be promoted.

[0003] The existing skin traction lifting frames are basically placed directly on the hospital bed or air cushion for use. Since the skin traction lifting frames are basically made of metal, if they are directly placed on the air cushion for use, on the one hand, it is easy to scratch the surface of the air cushion, affecting the life and air tightness of the air cushion. On the other hand, although there are inflatable mattresses that can adjust the lifting of the legs, back and other positions, the lifting height and lifting range are limited, which is still not conducive to the healing of patients with orthopedic fractures undergoing skin traction.

[0004] Therefore, a self-controlled lifting air cushion structure for orthopedic fracture skin traction patients is designed to change the above technical defects. Utility Model Content

DETAILED DESCRIPTION

[0024] This specific embodiment is a self-controlled air cushion structure for orthopedic fracture skin traction patients. The structural diagram is as follows: Figure 1-Figure 6 As shown, it includes an inflatable cushion 1, which is hollow inside. Two bottom plates 2 are fixedly installed symmetrically at the bottom of the inner cavity of the inflatable cushion 1. Two scissor-type connecting rods 3 are movably connected to the top surface of the bottom plate 2. The tops of the two scissor-type connecting rods 3 on the same side are movably connected to the same top plate 4. The side walls of the scissor-type connecting rods 3 are fixedly connected to limit rods 14. Limit grooves 15 are provided on the side walls of the bottom plate 2 and the top plate 4. The limit rods 14 are slidably connected to the limit grooves 15. Corrugated elastic fabrics 16 are fixedly connected to the side walls of the top plate 4. The corrugated elastic fabrics 16 are fixedly connected to the inflatable cushion 1. Cylinders 5 are installed on the side walls of the scissor-type connecting rods 3. Support components are provided on the top surface of the top plate 4. Adjustment components are provided on the rear side walls of the top plate 4.

[0025] Among them, the scissor-type link 3 is a mechanism, which is usually composed of two or more rods connected together. These rods are connected together through hinges, so that the system presents a scissors-like structure. The most commonly used functions are lifting or telescoping. Its structure is simple and belongs to the existing common technology, and will not be described in detail in this solution.

[0026] In addition, the present solution sets the lifting frame inside the inflatable cushion 1, and combines the two for use as a whole. When the lifting structure is not in use, it is in a compressed state, and occupies a smaller space inside the inflatable cushion 1, which does not affect the folding of the inflatable cushion 1. The corrugated elastic fabric 16 is set above the top plate 4 of the inflatable cushion 1. When the top plate 4 rises, the corrugated elastic fabric 16 can provide a larger space without causing pulling on other positions on the inflatable cushion 1.

[0027] like Figure 1 and Figure 2 As shown, the support assembly includes a solenoid valve 6 mounted on the side wall of the cylinder 5, the solenoid valve 6 is connected to the air pipe on the cylinder 5, the solenoid valve 6 is also connected to an inflation tube 7, an air bag 8 is fixedly connected to the top surface of the top plate 4, the middle of the air bag 8 is concave, and the inflation tube 7 passes through the top plate 4 and is connected to the air bag 8.

[0028] The electromagnetic valve 6 can change the direction of the airflow by controlling the power on and off of the electromagnetic coil. When the electromagnetic coil is powered on, the magnetic field generated will cause the valve to open or close, thereby changing the flow direction of the gas or liquid. Specifically, when the electromagnetic coil is powered on, the magnetic field will cause the piston or diaphragm in the valve to move, causing the valve to open or close, thereby changing the channel of the airflow or liquid flow and achieving a change in the direction of the airflow.

[0029] When the airflow passes through the solenoid valve 6 to drive the cylinder 5 to execute in place, the solenoid valve 6 changes the execution action, seals the cylinder 5, and injects the airflow into the airbag 8 at the same time, which is convenient for the patient to place his legs and increases the softness of the top plate 4; in addition, when the inflatable cushion 1 and the airbag 8 are inflated, the micro air pump can be turned off and used in conjunction with the one-way valve to prevent the airflow in the inflatable cushion 1 and the airbag 8 from overflowing.

[0030] like Figure 2 and Figure 5 As shown, the adjustment assembly includes a movable plate 9 movably connected to the side wall of the top plate 4, an electric push rod 10 is hinged on the bottom surface of the top plate 4 near the rear side, and the other end of the electric push rod 10 is hinged to the bottom surface of the movable plate 9. The movable plate 9 is rectangular, and a sponge pad 11 is fixedly connected to the top surface of the movable plate 9.

[0031] Specifically, in actual application, the extension distance of the electric push rod 10 can be controlled according to the patient's condition, so that the movable plate 9 can be opened to a suitable angle to facilitate the patient to place his limbs, and at the same time, the sponge pad 11 can be used to protect the patient's injured limbs.

[0032] In this embodiment, another alternative use method can be adopted for the sponge pad 11:

[0033] The sponge pad 11 is replaced with an airbag 8, and the inflation tube 7 can change the direction of the airflow through a three-way pipe or a solenoid valve 6 and other structures to expand the airbag 8 on the movable plate 9 and increase the softness of the surface of the movable plate 9. The improvement and use of the movable plate 9 can be selected according to actual needs.

[0034] like Figure 6 As shown, a cavity 12 is opened inside the top plate 4, and a plurality of heating tubes 13 are fixedly installed in the inner cavity of the top plate 4.

[0035] Specifically, the temperature control of the heating tube 13 can be achieved by a PID controller. The PID controller adjusts the power supply voltage or working time of the heating tube 13 according to the difference between the set target temperature and the actual temperature, so as to keep the temperature within the set range; when the actual temperature is lower than the set temperature, the PID controller increases the power supply voltage or working time of the heating tube 13; when the actual temperature is higher than the set temperature, the power supply voltage or working time is reduced to achieve the purpose of temperature control;

[0036] The heating tube 13 is usually made of a resistance wire or a heating element. The resistance wire is heated by electricity and transfers the heat to the surrounding medium. The heating tube 13 belongs to the existing mature technology, and its operation mode and principle are not introduced in detail in this solution.

[0037] Working principle: when it is necessary to support the legs of patients with fracture skin traction, first use a micro air pump to inflate the inflatable cushion 1. After the inflation is completed, adjust the pipeline to drive the cylinder 5. The cylinder 5 drives the scissor-type connecting rod 3 to open, thereby driving the top plate 4 to move upward. When the top plate 4 rises to a suitable height, it stops rising and turns the airflow to the inflation tube 7 through the solenoid valve 6 to expand the air bag 8 to increase the comfort of the patient with fracture skin traction. If the weather temperature is low or the patient feels cold, the heating tube 13 can be started to make the top plate 4 and the air bag 8 have heat, further increasing the patient's comfort and practicality.

[0038] All technical features in this embodiment can be freely combined according to actual needs.

[0039] The above embodiments are preferred implementation schemes of the present invention. In addition, the present invention can also be implemented in other ways. Any obvious replacement without departing from the concept of the present technical solution is within the protection scope of the present invention.
