[0022] In order to make the technical means, creative features, objectives and effects of the utility model easier to understand, the utility model is further described below with reference to specific diagrams. However, the utility model is not limited to the following implementation cases.
[0023] It should be noted that the structures, proportions, sizes, etc. illustrated in the drawings in this specification are only used to match the contents disclosed in the specification so that people familiar with this technology can understand and read them. They are not used to limit the conditions under which the present utility model can be implemented, so they have no substantive technical significance. Any structural modification, change in proportional relationship or adjustment of size should still fall within the scope of the technical contents disclosed in the present utility model without affecting the effects and purposes that can be achieved by the present utility model.
[0024] Good upper limb positioning mainly refers to a specific limb placement adopted during the rehabilitation process of hemiplegic patients in order to promote the recovery of limb function. This position helps to reduce muscle spasms, improve blood circulation, prevent joint stiffness and muscle atrophy, and thus promote the patient's recovery.
[0025] The overall position of the upper limbs in a good position is to place the upper limbs beside the body or properly supported in front of the body to reduce the impact of gravity on the limbs.
[0026] The utility model provides an upper limb good limb position auxiliary device for hemiplegic patients, which can keep the patient's wrist in a neutral position to avoid flexion or overextension; the fingers are naturally separated and slightly bent to avoid clenching or overextension; the forearm is semi-rotated and supported in front of the chest to reduce the burden on the patient's shoulder joint; the elbow is slightly bent to avoid being in a straight state for a long time. When using the upper limb good limb position auxiliary device, hemiplegic patients should keep their shoulders relaxed to avoid internal rotation or external rotation of the shoulder joint.
[0027] Figure 1 The present invention is a schematic structural diagram of an embodiment of an upper limb good limb positioning auxiliary device. Figure 2 yes Figure 1 A schematic structural diagram of another embodiment of a mid-upper limb good limb positioning auxiliary device.
[0028] from Figure 1 and Figure 2 It can be seen that the upper limb good limb position auxiliary device can include a bracket assembly 1 and an adjustment seat 2, and the adjustment seat 2 is connected to the bracket assembly 1.
[0029] Specifically, in this embodiment, the bracket assembly 1 is in four sections, and may include an elbow support 11, a forearm support 12, a wrist support 13, and a palm support 14 connected in series. It should be noted that: Figure 1 and Figure 2 The elbow support 11, forearm support 12 and wrist support 13 shown in the figure are all semi-enclosed supports: the elbow support 11 for supporting the patient's elbow is hemispherical with an arc-shaped cavity; the forearm support 12 for supporting the patient's forearm is semi-cylindrical with openings at both ends; the wrist support 13 for supporting the patient's wrist to prevent sagging is semi-cylindrical with openings at both ends.
[0030] However, the palm rest 14 for preventing the patient from making a fist or over-extending or sagging the palm may be as follows: Figure 1 The glove-like shell with five separated fingers as shown or Figure 2 The two ends shown are open cylindrical. Figure 1 The five-finger-separated glove-like design of the palm rest 14 shown can allow the patient's fingers to be naturally separated and slightly bent to avoid clenching a fist or over-extension. Figure 2 The palm support 14 shown is not limited by the size of the patient's palm and has stronger compatibility. Figure 1 The glove-shaped palm rest 14 shown in the figure is a left-hand glove-shaped palm rest 14. In practice, a right-hand glove-shaped palm rest 14 or a universal glove-shaped palm rest 14 can also be provided, which can be adapted to both hands by rotating the angle. The design of these two palm rests 14 allows both hands to be used. Specifically, the patient can rotate the palm rest 14 or adjust the direction of the palm to match the palm direction of the affected limb.
[0031] In an optional embodiment, the forearm support 12 and the wrist support 13 can also adopt a fully enclosed cylindrical design, surrounding the entire circumference of the patient's arm and wrist, or can be further used in conjunction with a fixing bandage or a lock buckle based on the above-mentioned half-enclosed design. In this way, the four-section design of the bracket assembly 1 can fix the patient's hemiplegic upper limb in a good limb position with the elbow extended, the forearm rotated in front of the chest, the wrist extended, and the fingers stretched flat.
[0032] In such Figure 1 and Figure 2In the embodiment shown, the elbow support 11 and the forearm support 12 can be connected by several slide bars 3, and the two ends of each slide bar 3 are respectively inserted into the butt ends of the elbow support 11 and the forearm support 12, so that the elbow support 11 and the forearm support 12 can adjust the relative position by sliding on the slide bars 3. The wrist support 13 and the forearm support 12 are slidably connected, and slide grooves 4 are provided on both sides of the wrist support 13, and the two sides of the forearm support 12 are inserted in the slide grooves 4 for installation. The palm support 14 is detachably sleeved on the outer periphery of the wrist support 13, so that the palm support 14 can rotate relative to the wrist support 13. In an optional embodiment, the palm support 14 and the wrist support 13 can be matched by magnetic attraction or slots or threaded interlocking to achieve that the palm support 14 is sleeved on the outer periphery of the wrist support 13 and can rotate.
[0033] The above-mentioned adjustment seat 2 may include a steering mechanism 21 and a lifting mechanism 22. One end of the steering mechanism 21 is fixedly connected to the elbow support 11 in the bracket assembly 1, and the other end is movably connected to the lifting mechanism 22 through a movable connection 5. When the patient needs to raise the upper limb position, the height of the lifting mechanism 22 can be adjusted. It should be noted that the steering mechanism 21 itself cannot be turned, because the movable connection 5 can turn relative to the lifting mechanism 22. Figure 1 and Figure 2 The movable connecting member 5 shown is a pin, and the steering mechanism 21 is connected to the lifting mechanism 22 through the pin, so that the steering mechanism 21 can rotate relative to the lifting mechanism 22 around the pin. Figure 1 and Figure 2 The figure shows the situation that the steering mechanism 21 rotates up and down relative to the lifting mechanism 22. In other optional embodiments, the steering mechanism 21 can also be set to rotate left and right relative to the lifting mechanism 22. One end of the steering mechanism 21 is fixedly connected to the elbow support 11. In this way, in actual use, when the patient needs to transfer the bracket assembly 1 to the position he needs, such as the chest, he only needs to adjust the position of the elbow support 11 to directly adjust the position of the forearm support 12, the wrist support 13 and the palm support 14. The positions of the supports relative to each other can be adjusted in detail through the above-mentioned slide bar 3 and slide groove 4, which will not be described in detail here.
[0034] In an optional embodiment, the movable connecting member 5 may be a pin, a bearing, a hinge, or a universal joint, and the lifting mechanism 22 may be a lifting column, an adjustable foot, or a telescopic rod. Figure 1 and Figure 2The figure only shows the case where the movable connecting member 5 is a pin and the lifting mechanism 22 is a lifting column. The lifting mechanism 22 is driven to rise and fall by an electric push rod 221 at the bottom. Specifically, the output end of the electric push rod 221 is connected to the internal transmission shaft, and the transmission shaft is connected to the lifting mechanism 22. In other optional embodiments, when the lifting mechanism 22 is a telescopic rod, the height can be adjusted manually.
[0035] In order to improve the comfort of the patient, a cushion cover is laid on the inner wall of the bracket assembly 1 to prevent the affected limb from directly contacting the hard wall of the bracket assembly 1. Specifically, the cushion cover is a soft cushion, which can provide additional comfort and pressure relief for the affected limb, which is especially important for patients who need to maintain a good upper limb position for a long time. In an optional embodiment, the cushion cover can also be made of antibacterial and waterproof materials to meet medical and hygienic requirements.
[0036] In other optional embodiments, an air bag may be provided in the cushion cover, and an air nozzle is provided on the air bag. When in use, air is inflated into the air bag from the air nozzle to expand the cushion cover to provide more comfortable support, or the inflated air bag can be used to fill the gap between the affected limb and the upper limb good limb position assisting device for patients with thinner limbs.
[0037] Furthermore, a massage component may be provided inside the cushion cover to massage and soothe the patient's affected limb. The massage component may be driven by a built-in motor and powered by a built-in battery.
[0038] In an optional embodiment, a plurality of ventilation holes may be provided on the cushion cover of the bracket assembly 1 and / or its inner wall to increase air circulation, reduce sweat moisture and heat accumulation inside the device, improve breathability to reduce the risk of bacterial growth, and increase comfort.
[0039] In order to enable the upper limb good limb position auxiliary device to be installed and fixed at any place where the patient is located, such as a bed or a wheelchair, a clamp 6 that can be fixedly clamped at a position such as a bed or a wheelchair is designed at the bottom of the adjustment seat 2 of the upper limb good limb position auxiliary device. The clamp 6 is fixedly connected to the bottom of the lifting mechanism 22 of the adjustment seat 2. In an optional embodiment, the clamp 6 and the adjustment seat 2 can be directly connected in an integrated manner, such as welding or fusion.
[0040] The second aspect of the present invention further provides a wheelchair, on the armrests of which the above-mentioned upper limb good limb positioning auxiliary device can be directly arranged.
[0041] In summary, the upper limb good limb position assistive device and wheelchair for hemiplegic patients provided by the utility model can be used in many scenarios such as hospitals, rehabilitation centers and personal homes. It can be widely used in hemiplegic patients who need additional support and stability to improve their quality of life and convenience of daily activities.
[0042] The preferred specific embodiments of the utility model are described in detail above. It should be understood that ordinary technology in the field can make many modifications and changes according to the concept of the utility model without creative work. Therefore, any technical solution that can be obtained by a technician in the technical field based on the concept of the utility model through logical analysis, reasoning or limited experiments on the basis of the existing technology should be within the scope of protection determined by the claims.
