DETAILED DESCRIPTION
[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.
[0023] Reference Figure 1-4 A multifunctional knee joint orthosis comprises an upper fixing ring 1, a lower fixing ring 2, a support rod 1 3 and a support rod 2 4, the support rod 1 3 and the support rod 2 4 are respectively fixedly connected to the side walls of the upper fixing ring 1 and the lower fixing ring 2, one end of the support rod 1 3 and one end of the support rod 2 4 are rotatably connected, an inner lining 5 is installed on the inner side of the upper fixing ring 1 and the lower fixing ring 2, and a plurality of through holes 6 for dissipating heat on the skin surface of the leg are provided on the side wall of the lining 5, a control box 9 is provided on the upper fixing ring 1, and an air intake component for intake air into the through hole 6 is provided inside the control box 9.
[0024] Reference Figure 2 , Figure 3 and Figure 4The air intake assembly includes two connecting cavities 7, which are respectively located inside the two inner liners 5, and the connecting cavities 7 are connected to the through hole 6. The control box 9 is sealed and slidably connected with a sliding plug 10. The control box 9 is connected with an air intake pipe 13, an air intake pipe 2 14, an exhaust pipe 15 and an exhaust pipe 2 16. The air intake pipe 13 and the exhaust pipe 2 16 are both located at the top of the control box 9, and the air intake pipe 2 14 and the exhaust pipe 1 15 are both located at the bottom of the control box 9. The air intake pipe 1 13 and the air intake pipe 2 14 are both provided with a check valve 2 18, and the exhaust pipe 1 15 and the exhaust pipe 2 16 are both provided with a check valve 17. The check valve 17 and the check valve The limiting directions of one-way valve 17 and one-way valve 18 are opposite. One-way valve 17 controls the air to be discharged only from control box 9. One-way valve 2 18 controls the outside air to enter the inside of control box 9. The lining 5 is provided with a connecting pipe 8 connected to the inside of the connecting cavity 7. Air intake pipe 1 13 and air intake pipe 2 14 are both connected to the connecting pipe 8. Under the action of the air intake assembly, the movement of the sliding plug 10 can drive the outside air to blow continuously to the legs, which can ensure the air permeability of the device and thus improve the user's comfort. Secondly, ensuring that the skin is breathable can also reduce the occurrence of skin diseases. The air intake assembly also includes a driving member, which is used to drive the movement of the sliding plug 10.
[0025] Reference Figure 1 and Figure 2 The driving member includes a pull rope 12 fixedly connected to the lower surface of the sliding plug 10, and one end of the pull rope 12 away from the sliding plug 10 is fixed to the side wall of the support rod 4. A spring 11 is provided between the upper surface of the sliding plug 10 and the inner top surface of the control box 9. Under the cooperation of the spring 11 and the pull rope 12, when the user bends and straightens his legs, air will be driven to blow toward the skin of the legs. In this way, no external power supply equipment is required for driving, which saves the cost of use.
[0026] Reference Figure 1 and Figure 2 A cooling sheet 19 and a heating wire 20 are embedded in the interior of the sliding plug 10, and a temperature control device 21 is fixedly connected to the side wall of the control box 9. The cooling sheet 19 and the heating wire 20 are electrically connected to the temperature control device 21. Specifically, the temperature control device 21 is composed of a thermostat, a relay and a power supply. The specific connection method and working principle are all existing technologies and are not an innovative part of the present utility model. They will not be elaborated here. By setting the temperature control device 21, the user can adjust the temperature of the air blown to the legs, which improves the flexibility of the device. In particular, when a higher temperature is set to blow hot air to the legs, the muscle tissue and nerves near the knee joint can be activated, which is also beneficial to the correction of the knee joint.
[0027] Reference Figure 1The lining 5 is made of sponge, and the upper fixing ring 1 and the lower fixing ring 2 are respectively connected to the two linings 5 through a detachable structure. Specifically, the detachable structure is composed of two Velcro sub-surfaces and two Velcro mother surfaces. The two Velcro sub-surfaces are respectively fixed on the inner sides of the upper fixing ring 1 and the lower fixing ring 2, and the two Velcro mother surfaces are respectively fixedly mounted on the lining 5. In this way, after long-term use, the user can remove the lining 5 for cleaning, which is convenient for the user.
[0028] Reference Figure 3 The inner side of the lining 5 has a wavy structure, which can reduce the contact area between the lining 5 and the leg skin, further improve the air permeability of the device, and is also conducive to the discharge of air in the through hole 6.
[0029] The specific working principle of the utility model is as follows:
[0030] After the user wears it, the upper fixing ring 1 is located above the joint, and the lower fixing ring 2 is located below the joint. When the user bends his knees, the drawstring 12 will be in a relaxed state and will not generate tension on the sliding plug 10. At this time, under the elastic force of the spring 11, the sliding plug 10 will move upward, thereby squeezing the air above the sliding plug 10 into the exhaust pipe 2 16. At the same time, the bottom of the sliding plug 10 is in a negative pressure state, and the outside air will be sucked into the bottom of the sliding plug 10 through the intake pipe 2 14. Subsequently, the air in the exhaust pipe 2 16 enters the connecting cavity 7 through the connecting pipe 8 and is ejected through the through hole 6, thereby ventilating and dissipating the heat on the skin surface, ensuring the air permeability of the device, thereby improving the comfort of the user. Conversely, when the user's legs are straightened, the drawstring 12 and the support The connection point of the rod 2 4 will be away from the control box 9, so that the pull rope 12 will be in a taut state and pull the sliding plug 10 downward, and the air below the sliding plug 10 will be squeezed into the exhaust pipe 1 15, and then enter the connecting pipe 8 and the connecting cavity 7 and spray out from the through hole 6, and at the same time, the outside air is sucked into the top of the sliding plug 10 through the air intake pipe 1 13. In summary, when the user's legs are bent or straightened, air will be continuously sprayed out from the through hole 6, thereby dissipating heat from the skin surface, thereby preventing the skin problems caused by overheating and dullness on the leg surface, improving the user's comfort, ensuring the good condition of the skin near the knee joint, and thus facilitating the correction effect of the knee joint. It is worth mentioning that the heat dissipation process is driven by the user's correction activities, saving the cost of use;
[0031] Furthermore, a cooling sheet 19 and a heating wire 20 are provided in the sliding plug 10, and both are connected to the temperature control device 21. The user can set a suitable temperature so that the air ejected from the through hole 6 can reach the preset temperature. In this way, for users who are afraid of high temperatures in seasons with higher temperatures, the cooling sheet 19 can be used to reduce the air in the control box 9, thereby achieving the purpose of timely heat dissipation for the skin of the legs, thereby improving the comfort of the user. Conversely, in cold seasons, the heating wire 20 can heat the air in the control box 9, thereby keeping the legs warm. This warmth or hot compress is also beneficial to the activation of nerves near the knee joint, thereby helping to shorten the correction process of the knee joint. In summary, this design improves the practicality and flexibility of the device, increases the diversity of the functions of the knee orthosis, and facilitates user use.
[0032] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
