Description

Technical Field

[0001] The present invention belongs to the technical field of medical rehabilitation equipment, and in particular relates to a postoperative rehabilitation device based on digital medicine. Background Art

[0002] The elbow postoperative rehabilitation device is a medical device used to assist patients in rehabilitation training after elbow surgery. It can help patients gradually restore joint flexion and extension, pronation and supination functions through passive movement or assisted active movement to prevent joint stiffness. It can also provide resistance training of different intensities to help patients strengthen muscles such as biceps and triceps, or promote local blood circulation and reduce postoperative pain and swelling through appropriate exercise and massage functions. In short, the rehabilitation device can provide stable support and protection to prevent patients from secondary injuries caused by improper movement during the rehabilitation process.

[0003] For example, a Chinese patent discloses an orthopedic elbow fracture postoperative rehabilitation device (patent announcement number: CN114732586A). By setting an air cushion and an air bag, when the arm is bent, the left and right fixed blocks are close to each other, and the hinge and the connecting plate are connected to allow the slide bar to slide into the inner wall of the sleeve, so that the air inside the sleeve is discharged into the air cushion through the connecting pipe. The tension of the air bag is greater than the surface tension of the air cushion. When the air in the sleeve is discharged into the air cushion on the two side panels, the corresponding air bag is expanded to a full state, which massages the inside of the patient's arm. When the arm is bent, the contraction dimension of the inner arm muscles increases, and the bulge of the air bag cooperates with the increase in muscle dimension to further improve the massage effect, and cooperates with the bending movement to improve muscle blood circulation and improve the rehabilitation effect.

DETAILED DESCRIPTION

[0017] like Figure 1 to Figure 9 As shown, A postoperative rehabilitation device based on digital medicine comprises an upper arm support and a lower arm support hinged to each other, the lower arm support comprises a first lower arm support 3 and a second lower arm support 4 which are arranged up and down and detachably connected, the first lower arm support 3 is smaller than the second lower arm support 4, and the first lower arm support 3 is buckled downwardly on the inner side of the second lower arm support 4 and fits together on the surface of the patient's forearm, of course, the surfaces of the first lower arm support 3 and the second lower arm support 4 which fit the patient's forearm are ergonomic, the first lower arm support 3 and the second lower arm support 4 are fixed to the forearm by a plurality of Velcro strips 20, the surface of the first lower arm support 3 which fits the arm is provided with a plurality of first lower arm massage bags which are interconnected, and the surface of the second lower arm support 4 which fits the arm is provided with a plurality of second lower arm massage bags which are interconnected Massage capsules, each first lower arm massage capsule and second lower arm massage capsule are evenly spaced and cover most of the surface of the forearm together; the end of the lower arm bracket away from the upper arm bracket is detachably connected to a plurality of lower arm extension blocks 6, each of the lower arm extension blocks 6 is arranged in an array along the length direction of the lower arm bracket and fits the arm together with the lower arm bracket, wherein the size of the lower arm extension blocks 6 arranged in sequence from the forearm to the wrist direction gradually decreases and conforms to the shape of the forearm, and the lower arm extension blocks 6 adjacent to each other on the left and right are detachably connected (the lower arm extension blocks 6 can be detachably connected by existing methods such as card block card slot matching, magnet matching, etc., which will not be further elaborated here), and each lower arm extension block 6 is also provided with a corresponding first lower arm massage capsule and a second lower arm massage capsule on the side surface that fits the arm;The upper arm support includes a first upper arm support 1 and a second upper arm support 2 which are arranged up and down and are detachably connected. The size of the first upper arm support 1 is smaller than that of the second upper arm support 2, and the first upper arm support 1 is buckled downwardly on the inner side of the second upper arm support 2 and fits together on the surface of the arm. The first upper arm support 1 and the second upper arm support 2 are also fixedly connected by a plurality of Velcro strips 20. A plurality of first upper arm massage bags which are interconnected are provided on the side of the first upper arm support 1 which fits the arm, and a plurality of second upper arm massage bags which are interconnected are provided on the side of the second upper arm support 2 which fits the arm. The second upper arm support 2 and the second lower arm support 4 are hinged to each other and rotate in a vertical plane, and a connecting ring 14 which is located outside the elbow joint is provided at the hinge, and the inner circle of the connecting ring 14 is spaced apart from the outer surface of the elbow joint, and the inner circle surface of the connecting ring 14 is aligned with the inner surface of the elbow joint. A first inflatable bag 9 and a second inflatable bag 10 are respectively arranged between the outer surfaces, the first inflatable bag 9 is connected with the adjacent first lower arm massage bag and the first upper arm massage bag, the second inflatable bag 10 is connected with the adjacent second lower arm massage bag and the second upper arm massage bag, and when the patient moves the elbow joint, the upper arm bracket and the lower arm bracket rotate and approach each other, the elbow joint and the connecting ring 14 squeeze the first inflatable bag 9 and the second inflatable bag 10 at the same time, so that the gas in the first inflatable bag 9 flows to the first upper arm massage bag and the first lower arm massage bag and inflates them, and the gas in the second inflatable bag 10 flows to the second upper arm massage bag and the second lower arm massage bag and inflates them, so that each massage bag 5 (the first lower arm massage bag, the first upper arm massage bag, the second lower arm massage bag and the second upper arm massage bag are collectively referred to for convenience of description and consistent with the context) massages the patient's arm. ;

[0018] As shown in the combined figure, the lower arm bracket is tightly attached to the outside of the patient's forearm by the first lower arm bracket 3 and the second lower arm bracket 4 in an up-and-down buckling state. The first lower arm bracket 3 and the second lower arm bracket 4 are both in a semicircular arc shape. Since the size of the first lower arm bracket 3 is smaller than the second lower arm bracket 4, when in use, the second lower arm bracket 4 is first placed flat on the table, and then the patient's forearm is placed on the inner side of the second lower arm bracket 4, and the first lower arm bracket 3 is vertically buckled toward the second lower arm bracket 4. When the first lower arm bracket 3 coincides with the arc center of the second lower arm bracket 4, the first lower arm bracket 3 can also The arm rest 4 is then moved to the inner side of the second lower arm support 4 for a certain distance until the inner side surface of the first lower arm support 3 abuts against the arm. At this time, the first lower arm support 3 and the second lower arm support 4 together form a sleeve 15 shape and are fixed outside the arm. This buckling method enables the lower arm support to adapt to forearms of different sizes within a certain range. Conversely, when the patient's forearm is larger, the first lower arm support 3 and the second lower arm support 4 respectively fit the upper and lower surfaces of the patient's forearm at intervals. Although there is a gap between the first lower arm support 3 and the second lower arm support 4, the first lower arm support 3 and the second lower arm support 4 are still in contact with the arm. The second lower arm bracket 4 can be made to be closely attached to the surface of the patient's forearm by adjusting the position of the Velcro 20, and there is no need to worry about the problem of insecure fixation; similarly, the working principle and operation logic of the first upper arm bracket 1 and the second upper arm bracket 2 are similar to those of the lower arm bracket, and can adapt to upper arms of different sizes within a certain range. The specific working principle will not be described in detail here. The size-adjustable upper arm bracket and lower arm bracket can effectively improve the applicable scope of the rehabilitation device (a short name for a postoperative rehabilitation device based on digital medicine); and, since one end of the lower arm bracket is detachably connected with a plurality of lower arm extension blocks 6 with similar shapes, the length of the lower arm bracket can be adjusted within a certain range by disassembling and assembling a suitable number of lower arm extension blocks 6 at one end of the lower arm bracket, so that the lower arm bracket is suitable for patients with different forearm lengths within a certain range. Of course, the upper arm bracket extension block can also be set at the end of the upper arm bracket away from the lower arm bracket, but according to the human body structure, the length of the upper arm is shorter than the forearm. Therefore, the fixed length of the upper arm bracket can meet the needs of most patients, and only the length of the lower arm bracket needs to be adjusted;When the patient needs to move the elbow joint, the forearm is lifted and bent toward the upper arm. During this movement, the elbow joint and the connecting ring 14 squeeze the first inflatable bag 9 and the second inflatable bag 10 at the same time, so that the gas in the first inflatable bag 9 flows to the first upper arm massage bag and the first lower arm massage bag connected thereto, and the gas in the second inflatable bag 10 flows to the second lower arm massage bag and the second upper arm massage bag connected thereto, so that each massage bag 5 is deformed and expanded to massage the surface of the patient's arm. On the contrary, when the forearm and the upper arm are straightened, the first inflatable bag 9 and the second inflatable bag 10 will not be squeezed, and each massage bag 5 will not be deformed and expanded. By repeatedly bending the elbow joint back and forth, the shape of each massage bag 5 can be reciprocated between expansion and non-expansion, so as to massage the patient's arm, accelerate blood flow, and promote wound healing. ;

[0019] In this embodiment, two arc-shaped first connecting blocks 7 are connected between the second upper arm bracket 2 and the connecting ring 14, and the two first connecting blocks 7 are symmetrically arranged about the axis of the length direction of the upper arm bracket, the surface of the connecting ring 14 is provided with two arc-shaped first through holes 11, the two first through holes 11 are symmetrically arranged about the vertical axis of the connecting ring 14, and a movable block 12 is slidably connected in each of the first through holes 11, and the surface of the second lower arm bracket 4 close to the connecting ring 14 is connected with two arc-shaped second connecting blocks 8, and the two second connecting blocks 8 are symmetrically arranged about the axis of the length direction of the lower arm bracket, the surface of each second connecting block 8 is provided with an arc-shaped second through hole 13 arranged along its length direction, the two second connecting blocks 8 are respectively arranged on both sides of the connecting ring 14, and one end of each movable block 12 passes through the first through hole 11 and the second through hole 13 in sequence and is threadedly connected to the limiting block 21, the limiting block 21 is arranged at an interval between the second connecting block 8, and the outer surface of each movable block 12 is sleeved with a spring located between the limiting block 21 and the second connecting block 8.

[0020] As shown in the combined figure, when the patient's elbow joint is reciprocatingly bent, the upper arm remains stationary, and when the forearm bends toward the upper arm, the forearm will simultaneously drive the lower arm bracket and the second connecting block 8 to rotate, so that the second connecting block 8 rotates around the center of the movable block 12, and the second through hole 13 limits the bending amplitude of the lower arm bracket, thereby ensuring the stability of the patient when doing bending exercises; when the patient's forearm rotates around the elbow joint in a small range, it will simultaneously drive the lower arm bracket and the second connecting block 8 to rotate along the center of the connecting ring 14, and the second connecting block 8 will drive the movable block 12 to reciprocate along the length direction of the first through hole 11, wherein, since the outer surface of the movable block 12 is sleeved with a spring located between the limit block 21 and the second connecting block 8 (combined with Fig. 9As shown in the figure), when the forearm bracket drives the second connecting block 8 to rotate, the gap between the limit block 21 and the second connecting block 8 facilitates the rotation of the patient's arm (provides sufficient margin for the rotation between the upper arm bracket and the lower arm bracket), and the spring can always abut the limit block 21 and the second connecting block 8, so that there is a certain damping when the arm rotates, thereby ensuring the stability of the arm during rotation. Of course, the spring compression amount can be indirectly adjusted by rotating the limit block 21 and adjusting the distance between the limit block 21 and the movable block 12, thereby realizing the adjustment of the rotational damping, which can effectively meet the patient's pursuit of different damping when rotating the arm, and effectively improve the scope of application of the device.

[0021] In this embodiment, the inner ring surface of the connecting ring 14 close to the outer side of the elbow joint is fixedly connected with a plurality of sleeves 15, and each sleeve 15 is arranged at intervals along the circumference of the connecting ring 14, and one end of each of the sleeves 15 is connected to the outer surface of the adjacent second upper arm bracket 2 by a plurality of connecting sleeves 16, and each of the connecting sleeves 16 is penetrated by a connecting piece 17, which is cylindrical, and one end of the connecting piece 17 away from the connecting sleeve 16 is fixedly connected to the surface of the second lower arm bracket 4, and the second inflatable bag 10 is arranged between the elbow joint and the connecting sleeve 16, and the second airbag is fixedly connected to the connecting sleeve 16 and the surface of the connecting ring 14.

[0022] As shown in the figure, when the elbow joint is bent, the lower arm bracket will rotate toward the upper arm bracket. At this time, the second lower arm bracket 4 will simultaneously drive one end of each connecting piece 17 to slide out of the connecting sleeve 16, so that one side surface of the second air bag 10 is always in contact with the connecting sleeve 16 and the surface of the connecting piece 17, ensuring that when the elbow joint is bent, it will squeeze the second air bag 10 together with the connecting piece 17 and the connecting sleeve 16, and squeeze the gas in the second air bag 10 to the second lower arm massage bag and the second upper arm massage bag connected thereto. Similarly, when the forearm rotates around the elbow joint, it will also simultaneously drive all the connecting pieces 17 to extend or retract into the connecting sleeve 16, which can effectively ensure that the second air bag 10 will be squeezed when the elbow joint moves.

[0023] In this embodiment, the inner sides of the upper arm bracket, the lower arm bracket and the lower arm extension block 6 are also provided with a fixing plate 18 and a guide air bag 19 that match their shapes in sequence from the inside to the outside, and the surfaces of the lower arm bracket, the upper arm bracket and the lower arm extension block 6 and the corresponding fixing plates 18 together form an air guide chamber, and the first upper arm massage bag, the second upper arm massage bag, the first lower arm massage bag and the second lower arm massage bag are respectively connected to each other with the corresponding guide air bags 19, and the surface of each of the fixing plates 18 is provided with a plurality of through holes for the first upper arm massage bag, the second upper arm massage bag, the first lower arm massage bag and the second lower arm massage bag to pass through, and the surfaces of each of the fixing plates 18 and the guide air bags 19 are provided with a plurality of air holes 22 (combined with Figure 4 and Figure 6 As shown), the outer surfaces of the upper arm bracket and the lower arm bracket are fixed with fans connected to the interior thereof (the fans are not shown in the figure), and the airflow blown out by the fans enters the air guide chamber and passes through each air hole 22 to dissipate heat to the arm.

[0024] As shown in the figure, each lower arm extension block 6 and the corresponding fixing plate 18 together form an independent air guide chamber. When the lower arm extension block 6 is fixedly connected to the lower arm bracket, the air guide chambers of the two will also be interconnected; through the setting of the fixing plate 18 and the guide air bag 19, it is effectively ensured that after the first inflatable bag 9 and the second inflatable bag 10 are squeezed, the gas inside them will be guided to the massage bag 5 connected thereto, and a plurality of air holes 22 are provided on the surface of each guide air bag 19 and the fixing plate 18, so that the airflow blown by the fan into the lower arm bracket and the upper arm bracket can be blown toward the patient's arm through the air holes 22 and dissipate heat to the arm, thereby effectively improving the comfort of the patient when wearing the postoperative rehabilitation device.

[0025] In this embodiment, the surface of each fixing plate 18 that contacts the patient's skin is provided with an electric heating plate for adjusting the temperature of the surface of the fixing plate 18 to improve the patient's comfort when using it in winter.

[0026] In the present embodiment, the first inflatable bag 9 and the second inflatable bag 10 are respectively connected to an air pump for inflating them (the air pump is not shown in the figure, and its disassembly can be achieved by snap fasteners or other existing known solutions, which will not be elaborated here), and each of the air pumps is detachably arranged on the corresponding upper arm bracket and lower arm bracket surface.

[0027] By inflating the first inflatable bag 9 and the second inflatable bag 10 with an air pump, each massage bag 5 can be actively deformed and expanded, and the patient no longer needs to bend his arm to achieve arm massage. This is suitable for patients whose elbow joints are inconvenient to bend, while they can also enjoy the massage function. Of course, for patients who can move their elbow joints, the air pump can also be disassembled to facilitate the patient's arm movement.

[0028] In this embodiment, the surface of each fixing plate 18 that contacts the patient's skin is connected to multiple temperature sensors and multiple pressure sensors, and each of the temperature sensors, pressure sensors, electric heating plates, fans and air pumps is electrically connected to a central controller.

[0029] The central controller monitors the temperature of the patient's arm surface in real time, and can control the start and stop of the electric heating plate and the fan according to the preset program, ensuring that the temperature is appropriate when the patient wears the upper arm support and lower arm support, and still can obtain good comfort, reducing the patient's discomfort. The pressure sensor can facilitate medical staff or operators to correctly wear the upper arm support and lower arm support to prevent them from being misplaced or too tight when worn and fixed, effectively improving the comfort of the device when used.

[0030] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made in form and details without departing from the scope defined by the claims of the present invention.
