At present, when the limb is trained after the operation, a device capable of supporting part or all of the weight of the patient is needed to enable the patient who cannot walk or temporarily cannot completely walk to stand and walk, so that the patient can recover part of the walking ability through the device, which is beneficial to avoid muscle atrophy of the patient and improve the fracture recovery speed. The orthopedic nursing auxiliary walking device in the prior art mainly realizes this function by supporting the patient.

[0025] A plurality of threaded holes are formed at the top of the upper support 1, a plurality of through holes 19 are formed at the top of the fixed plate 7, the through holes 19 movably sleeved with bolts 18, and the bottom ends of the bolts 18 are threadedly installed at the top of the upper support 1; As shown in Figure 2 and Figure 3 The adaptive plate 8 is fixed at the top of the upper support 1 by the fixed plate 7 and the bolts 18, in order to adapt to users with different body shapes, the fixed plate 7 and the upper support 1 can be designed to be detachable, and are fixed by the bolts 18, a plurality of through holes 19 are formed at the top of the fixed plate 7, the horizontal position of the fixed plate 7 can be moved to align the threaded holes at the top of the upper support 1 with the through holes 19, and the left and right adjustment function of the adaptive plate 8 is realized.

[0026] Among them, the inner side of the adapter plate 8 is fixedly connected with a protective pad 10, which is made of a sponge block, and the top of the adapter plate 8 is glued with a buffer pad 9, which is made of a rubber block; The protective pad 10 is made of a sponge block, which is matched with the adapter plate 8 to wrap around the user's upper body, thereby providing a buffer between the user and the adapter plate 8. The sponge material is breathable, which can prevent the skin from sweating and improve comfort. The cushioning pad 9 can provide a cushioning wrapping for the top tip edge of the adapter plate 8.

[0027] The adapter plate 8 is in a "U" shape, and the bottom of the adapter plate 8 is provided with a circular chamfer; The "U"-shaped design of the adapter plate 8 enables it to adapt to the user's upper body, and the arc chamfer at the bottom can prevent the user from being scratched when in contact.

[0028] Among them, the axial cross-section shape of the negative pressure column 17 is an "I" shape, and the outer surface of the negative pressure column 17 is movably sleeved with a spring three 20, and the two ends of the spring three 20 are elastically connected to the mounting frame 12 and the negative pressure column 17 respectively. The inner wall of the negative pressure groove 25 is a stepped shape with a thick bottom and a narrow top. The diameter of the middle part of the negative pressure column 17 is smaller than the inner diameter of the bottom of the negative pressure groove 25. The top of the negative pressure column 17 is sealed and sleeved on the top of the negative pressure groove 25, and the top of the negative pressure column 17 is provided with a cylindrical protrusion; like Figure 4 As shown, the moving block 23 and the negative pressure column 17 are arranged one above and one below, so that the inner cavity of the connecting pipe 15 can automatically inhale the external gas and send it into the inner cavity of the airbag 14 under the positive pressure of the pumping structure 16. When the pumping structure 16 presses and sends positive pressure air into the connecting pipe 15, the negative pressure column 17 is firmly stuck in the negative pressure groove 25 because it is just below, and the moving block 23 moves upward under the positive pressure and opens the fixing ring 21, so that the gas can enter the inner cavity of the airbag 14, and the pumping structure 16 generates a positive pressure on the connecting pipe 15 when it is restored. 5, since the movable block 23 is limited and abutted by the fixing ring 121 and cannot move, the negative pressure column 17 automatically moves upward, opens the negative pressure groove 25, connects the inner cavity of the connecting pipe 15 with the outside, and sends air into the inner cavity of the connecting pipe 15 and the inflating structure 16. This design realizes the one-way valve function of the device. When the device is not in use, the negative pressure column 17 can be squeezed upward, and the cylindrical protrusion at the top of the negative pressure column 17 can push the movable block 23 open, deflate the airbag 14, and thus restore the device to its original state. This design is easy to use.

[0030] Wherein, the friction plate 62 is made of asbestos-based material, and the roller 51 is made of cast iron, and a gap is left between the top of the outer surface of the friction plate 62 and the roller 51; The bottom of the friction plate 62 can be in contact with the roller 51 to generate friction and limit the rotation of the roller 51, thereby reducing the speed of the device and ensuring safety in use.

[0031] Working principle: When the device is in use, first, the user enters the inside of the upper support 1 and leans between the two sets of adapter plates 8, so that the armpit is on the outer surface of the air bag 14, the distance between the two sets of adapter plates 8 is adjusted according to the trapezoidal shape of the patient, and is fixed through the bolts 18, and the upper body of the user is wrapped by the protective pads 10 inside the adapter plates 8, Then, repeatedly press the inflation structure 16, and generate positive pressure in the inner cavity of the communication pipe 15, as Figure 3 And Figure 4 As shown, when the inflation structure 16 is pressed, the inner cavity of the communication pipe 15 enters positive pressure and exerts pressure on the negative pressure column 17 and the moving block 23 respectively, the negative pressure column 17 is firmly clamped in the negative pressure groove 25, and the moving block 23 drives the adapter frame 24 upward and opens the fixed ring one 21, so that the positive pressure gas enters the inner cavity of the air bag 14 through the fixed ring one 21, the adapter frame 24, the moving block 23 and the fixed ring two 22, when the inflation structure 16 is pressed to the bottom and restores its volume, the inner cavity of the communication pipe 15 generates negative pressure, at this time, the moving block 23 is sealed downward on the top of the fixed ring one 21 under the action of negative pressure, and the negative pressure column 17 moves upward under the action of negative pressure, opens the negative pressure groove 25, and allows the inner cavity of the communication pipe 15 and the inflation structure 16 to enter the outside air to balance the air pressure, then repeatedly press the inflation structure 16 until the air bag 14 is filled, at this time, the air bag 14 is in full contact with the armpit of the user and the skin around it, and the user gets buffering support; Finally, the user supported by the air bag 14 and the adapter plate 8 walks and drives the roller 51 to rotate, when the speed of the device is too fast, the user can hold the connecting rod 65 with both hands and press downward, which drives the moving plate 61 and the friction plate 62 to move downward, at this time, the friction plate 62 contacts the rotating roller 51 and generates friction, thereby limiting the movement speed of the device and ensuring safety in use.

[0032] It should be noted that the above examples are only used to illustrate the technical solutions of the present application but not limit the present application.
