Description

Technical Field

[0001] The present invention relates to the field of supporting equipment, and in particular to a medical auxiliary supporting device. Background Art

[0002] In the field of medical care, auxiliary support devices are indispensable and important equipment, especially when dealing with the personalized needs of different patients. At present, leg support has become a major challenge for patients who are bedridden for a long time, have lower limb dysfunction or are in the rehabilitation stage. Traditional support devices often have problems such as inconvenient adjustment, insufficient support strength, and poor comfort, making it difficult to meet the diverse needs of patients. For example, for patients with leg muscle atrophy, existing devices are difficult to provide sufficient support to assist them in standing or moving; for patients in the rehabilitation stage, the device needs to be able to be flexibly adjusted according to the rehabilitation process to adapt to their increasing limb function.

[0003] For example, the Chinese invention patent CN115252097A discloses an auxiliary support device for bone setting. Its specification discloses that nuts are generally assembled on the screw rod in the early stage of manufacturing, and it is not convenient to increase or decrease the number of nuts in the later stage. However, the number of nuts required to fix and support the limbs varies depending on the length of the patient's limbs, the location of the fracture, and the number of fractures. If too many nuts are set on the screw rod, it will be inconvenient to use during bone setting. If the number of nuts set is insufficient, it cannot meet the needs of bone setting.

[0059] The support wheel 519 is in contact with both sides of the hinge chain 502 under the condition of being able to rotate, and can be arranged in the gap between the two hinge chains 502 after being retracted toward the spray outlet 518 through the strip rod.

[0060] Embodiment 2 further optimizes a medical auxiliary support device provided in Embodiment 1. Specifically, Figure 6 , Figure 7 and Figure 8 As shown, the support structure 7 includes a ratchet cylinder 701 fixedly connected to the base 6, a pawl button 702 is slidably connected to the ratchet cylinder 701, and a ratchet of the ratchet cylinder 701 penetrates the ratchet cylinder 701 through a rotating shaft and is fixedly connected to a fixing rod 703.

[0061] The ratchet structure is composed of a ratchet in a ratchet cylinder 701 and a ratchet button 702 located in the ratchet cylinder 701. Since the ratchet structure is an existing structure, the structure in the ratchet cylinder 701 is not disclosed.

[0062] The supporting structure 7 further includes an articulated block 704 articulated on the fixing rod 703 , and a buffer cylinder 705 is fixedly connected to the articulated block 704 .

[0063] The end of the fixing rod 703 is consistent with the horizontal length of the backrest 3 after rotating around the circular portion on the side handle 2.

[0064] Further, such as Figure 7 and Figure 8 As shown, the support structure 7 also includes a secondary rod 706 rotatably connected to the fixed rod 703, an anti-drop sheet 7061 is slidably connected to the fixed rod 703, a return spring 707 is fixedly connected to the secondary rod 706, and the other end of the return spring 707 is fixedly connected to the fixed rod 703.

[0065] The auxiliary rod 706 is stored by the anti-dropping piece 7061.

[0066] The supporting structure 7 also includes a plurality of hooks 708 fixedly connected to the auxiliary rod 706, a card slot 709 is provided on the chair body 1, a receiving plate 710 is hinged on the chair body 1, a fixing strip 711 is fixedly connected to the backrest 3, and a card plate 712 is fixedly connected to the fixing strip 711.

[0067] With the help of the receiving plate 710, the safety and stability of the device can be improved when it is set horizontally.

[0068] The use process of a medical auxiliary support device provided by the present invention is as follows:

[0069] 1. In daily use, since the ends of the hinge chain 502 are in a relaxed state, the chain structure is loose and will not form a Figure 1 and Figure 2 The arched structure shown in the figure makes it impossible for the patient to sit on the device. The figure is only for displaying the structure. During use, try not to let the chain structure touch the ground. After the patient sits on the chair body 1, the patient's legs are placed in a state that is convenient for recovery, and the uninjured part of the patient is set above it through the force frame 511. At this time, the air pump box air duct 505 starts to pump air to cool the lower part of the patient and blow away impurities. During this process, the gas is discharged through the air jet hole 504. Since the air jet hole 504 and the air guide hole 513 are on the same plane, some air enters the inflatable strap 512 through the air guide hole 513 to prevent the contact part from being injured. The motor and the winding roller provide temporary support force by pulling the stretching belt 5071, so that the hinge chain 502 is stretched. In this process, since the patient's legs are above it, the chain structure composed of the hinge chain 502 is close to the curve of the patient's legs;

[0070] 2. With the assistance of medical workers, the hinge chain 502 at a specific point is determined to contact the uninjured part of the patient, so that the support force is adapted to the injured or special leg curve of the user. Before determining the approximate fit of the hinge chain 502, the hinge point of the hinge chain 502 can be fixed using the tightening knob 508, so that the fit curve is finally determined. Thereafter, the electric push rod 515 pushes out the working slide 514, which slides at the bottom of the hinge chain 502 and finally moves to the end of the curve to provide support force. When the support wheel 519 moves to the end, The support wheel 519 can be retracted inwards so that the support wheel 519 is located on the inner side of the hinge chain 502. At this time, the support wheel 519 is stuck in the gap between the two hinge chains 502 to prevent the end from moving. At the same time, the medicine bag 516 is stretched and flattened under the action of the spring at its end, and the medicine is applied to the inconvenient places on the bottom of the patient through the spray outlet 518. At the same time, the bottom inflation bag 517 is inflated to squeeze the medicine bag 516 to completely discharge the medicine liquid. At this time, the inflation bag 517 is located at the bottom of the hinge chain 502 to fill the uneven places and provide a shock-absorbing effect.

[0071] 3. During use, since the patient's legs are placed on the force-bearing frame 511 through the inflatable strap 512, the fan-shaped groove of the connecting roller 509 is in close contact with the fixing frame 503 under gravity. Since the spacing between the fixing frames 503 cannot be changed, the fan-shaped groove of the connecting roller 509 is stuck on the fixing frame 503, so that the connecting roller 509 cannot move in this state, ensuring that the binding part of the patient will not be displaced due to external force during the process, causing danger;

[0072] 4. When the backrest 3 needs to be lowered to make the whole device horizontal, the pawl button 702 can be pressed to allow the fixed rod 703 on the ratchet cylinder 701 to rotate. At this time, after the fixed rod 703 is horizontal, the buffer cylinder 705 is flipped to face the backrest 3, and the anti-slip sheet 7061 is slid to make the auxiliary rod 706 pop out to act as a supporting leg, and the receiving plate 710 is flipped to allow the card plate 712 on the fixing bar 711 to enter the card slot 709 to complete the horizontal placement, so that the device can be more stable. At the same time, the auxiliary rod 706 can act as a supporting component for hanging water when the fixed rod 703 is in the vertical state.
