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.

[0004] Although the above technical solution provides a postoperative rehabilitation device for elbow joints, the arm sizes of each patient are not the same, and the arms of patients of different age groups are even more different. The above technical solution cannot provide postoperative rehabilitation treatment for patients with arms of different sizes, and its scope of application is limited. Summary of the invention

[0005] In view of this, the purpose of the present invention is to provide a postoperative rehabilitation device based on digital medicine to solve the problem that the current postoperative rehabilitation device for elbow joint cannot be applied to the treatment of patients with arms of different sizes and has a limited scope of application.

The first air bag is communicated with the first lower arm massage sacs and the first upper arm massage sacs. The second air bag is communicated with the second lower arm massage sacs and the second upper arm massage sacs. When the upper arm bracket and the lower arm bracket rotate and approach each other, the elbow joint and the connecting ring simultaneously squeeze the first air bag and the second air bag, and respectively inflate the first lower arm massage sacs, the first upper arm massage sacs, the second lower arm massage sacs and the second upper arm massage sacs.

[0007] Furthermore, two arc-shaped first connecting blocks are connected between the second upper arm bracket and the connecting ring, and the two first connecting blocks are symmetrically arranged about the axis in the length direction of the upper arm bracket.

Moreover, the first upper arm massage bladder, the second upper arm massage bladder, the first lower arm massage bladder and the second lower arm massage bladder are respectively communicated with the corresponding guiding airbags. A plurality of through holes for the first upper arm massage bladder, the second upper arm massage bladder, the first lower arm massage bladder and the second lower arm massage bladder to pass through are formed on the surface of each fixing plate. A plurality of mutually communicated air vents are formed on the surfaces of each fixing plate and the guiding airbag.

Similarly, the lower arm bracket is also split into a first lower arm bracket and a second lower arm bracket. By adjusting the distances between the first upper arm bracket, the second upper arm bracket, the first lower arm bracket and the second lower arm bracket, the arms of patients with different sizes can be fixed. And by disassembling and assembling the lower arm extension block at one end of the lower arm bracket, patients with forearms of different lengths within a certain range can be adapted, effectively improving the applicable range of the present invention. Moreover, by providing components such as the first connecting block, the second connecting block and the connecting ring between the upper arm bracket and the lower arm bracket, not only can the elbow joint of the patient be bent at a certain angle, but also the forearm can be rotated within a small range, further improving the freedom degree during the recovery of the patient's elbow joint and effectively improving the recovery efficiency of the patient.

Detailed implementation manners

[0028] As Figures 1 to 9 shown

[0029] A postoperative rehabilitation device based on digital medicine, comprising an upper arm bracket and a lower arm bracket which are hinged to each other. The lower arm bracket includes a first lower arm bracket 3 and a second lower arm bracket 4 which are arranged up and down and detachably connected. The size of the first lower arm bracket 3 is smaller than that of the second lower arm bracket 4, and the first lower arm bracket 3 is buckled downward on the inner side of the second lower arm bracket 4 and they jointly fit on the surface of the patient's forearm. Of course, the surfaces of the first lower arm bracket 3, the second lower arm bracket 4 and the patient's forearm conform to ergonomics. The first lower arm bracket 3 and the second lower arm bracket 4 are fixed on the forearm by a plurality of magic tapes 20. The surface of the first lower arm bracket 3 that fits the arm is provided with a plurality of mutually connected first lower arm massage sacs, and the surface of the second lower arm bracket 4 that fits the arm is provided with a plurality of mutually connected second lower arm massage sacs. Each of the first lower arm massage sacs and the second lower arm massage sacs are evenly spaced and jointly cover most of the surface of the forearm. One end of the lower arm bracket far from the upper arm bracket is detachably connected with a plurality of lower arm extension blocks 6. Each of the lower arm extension blocks 6 is arrayed along the length direction of the lower arm bracket and jointly fits the arm with the lower arm bracket. Among them, the sizes of the lower arm extension blocks 6 arranged in sequence from the forearm to the wrist direction gradually decrease and conform to the shape of the forearm, and the adjacent lower arm extension blocks 6 on the left and right are detachably connected (the lower arm extension blocks 6 can be detachably connected by existing methods such as snap-fit and magnet cooperation, and will not be further elaborated here). The side surface of each lower arm extension block 6 that fits the arm is also provided with corresponding first lower arm massage sacs and second lower arm massage sacs;The upper arm bracket includes a first upper arm bracket 1 and a second upper arm bracket 2 which are arranged up and down and detachably connected. The size of the first upper arm bracket 1 is smaller than that of the second upper arm bracket 2. The first upper arm bracket 1 is buckled downward on the inner side of the second upper arm bracket 2 and they jointly fit on the arm surface. The first upper arm bracket 1 and the second upper arm bracket 2 are also fixedly connected by a plurality of magic tapes 20. On the side of the first upper arm bracket 1 that fits the arm, there are a plurality of interconnected first upper arm massage bladders. On the side of the second upper arm bracket 2 that fits the arm, there are a plurality of interconnected second upper arm massage bladders. The second upper arm bracket 2 and the second lower arm bracket 4 are hinged to each other and rotate in a vertical plane, and there is a connecting ring 14 located outside the elbow joint at the hinge. The inner circle of the connecting ring 14 is spaced from the outer surface of the elbow joint. A first air bag 9 and a second air bag 10 are respectively arranged between the inner circle surface of the connecting ring 14 and the inner and outer side surfaces of the elbow joint. The first air bag 9 is communicated with the adjacent first lower arm massage bladder and first upper arm massage bladder. The second air bag 10 is communicated with the adjacent second lower arm massage bladder and second upper arm massage bladder. And when the patient moves the elbow joint and the upper arm bracket and the lower arm bracket rotate and approach each other, the elbow joint and the connecting ring 14 simultaneously squeeze the first air bag 9 and the second air bag 10, so that the gas in the first air bag 9 flows into the first upper arm massage bladder and the first lower arm massage bladder and inflates them, and the gas in the second air bag 10 flows into the second upper arm massage bladder and the second lower arm massage bladder and inflates them, so that each massage bladder 5 (a collective term for the first lower arm massage bladder, the first upper arm massage bladder, the second lower arm massage bladder and the second upper arm massage bladder, for convenient description, consistent in the context) massages the patient's arm.;

[0030] As shown in the figure, the lower arm bracket is formed by the first lower arm bracket 3 and the second lower arm bracket 4 which are buckled up and down and closely attached to the outer side of the patient's lower arm. Both the first lower arm bracket 3 and the second lower arm bracket 4 are semi-circular arcs. Since the size of the first lower arm bracket 3 is smaller than that of the second lower arm bracket 4, when in use, first place the second lower arm bracket 4 flat on the table, then place the patient's lower arm inside the second lower arm bracket 4, and vertically buckle the first lower arm bracket 3 towards the second lower arm bracket 4. When the centers of the arcs of the first lower arm bracket 3 and the second lower arm bracket 4 coincide, the first lower arm bracket 3 can also continue to move a certain distance towards the inner side of the second lower arm bracket 4 until the inner surface of the first lower arm bracket 3 abuts against the arm. At this time, the first lower arm bracket 3 and the second lower arm bracket 4 together form a shape similar to the sleeve 15 and are fixed outside the arm. This buckling method enables the lower arm bracket to adapt to forearms of different sizes within a certain range. On the contrary, when the patient's forearm is larger, the first lower arm bracket 3 and the second lower arm bracket 4 are respectively attached to the upper and lower part surfaces of the patient's forearm at intervals. Although there is a gap between the first lower arm bracket 3 and the second lower arm bracket 4, the position of the adjustable magic tape 20 can be adjusted between the first lower arm bracket 3 and the second lower arm bracket 4, and still enable the lower arm bracket to closely adhere to the surface of the patient's forearm, without worrying 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 also 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 elaborated here. The adjustable upper arm bracket and lower arm bracket can effectively improve the applicable range of this rehabilitation device (abbreviation of a postoperative rehabilitation device based on digital medicine). Moreover, since one end of the lower arm bracket is detachably connected with a plurality of lower arm extension blocks 6 similar in shape to it, the length of the lower arm bracket can be adjusted within a certain range by disassembling and installing an appropriate number of lower arm extension blocks 6 at one end of the lower arm bracket, so that the lower arm bracket is applicable to patients with different forearm lengths within a certain range. Of course, an upper arm bracket extension block can also be set at the end of the upper arm bracket far from the lower arm bracket. However, according to the human body structure, the length of the upper arm is shorter than that of the forearm. Therefore, the fixed-length upper arm bracket can already meet the needs of the vast majority of 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 towards the upper arm. During this movement, the elbow joint and the connecting ring 14 simultaneously squeeze the first inflatable bag 9 and the second inflatable bag 10, causing the gas in the first inflatable bag 9 to flow into the first upper arm massage bag and the first lower arm massage bag connected to it, and the gas in the second inflatable bag 10 to flow into the second lower arm massage bag and the second upper arm massage bag connected to it, causing each massage bag 5 to deform and expand, massaging the surface of the patient's arm. Conversely, when the forearm and the upper arm are straightened, the first inflatable bag 9 and the second inflatable bag 10 are not squeezed, and each massage bag 5 does not deform and expand. By repeatedly bending the elbow joint, the shape of each massage bag 5 can be reciprocally converted between expansion and non-expansion, achieving the massage of the patient's arm, accelerating blood flow, and promoting the healing of injuries.

[0031] 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 in the length direction of the upper arm bracket. Two arc-shaped first through holes 11 are formed on the surface of the connecting ring 14, and the two first through holes 11 are symmetrically arranged about the vertical axis of the connecting ring 14. An activity block 12 is slidably connected in each first through hole 11. Two arc-shaped second connecting blocks 8 are connected to the surface of the second lower arm bracket 4 close to the connecting ring 14, and the two second connecting blocks 8 are symmetrically arranged about the axis in the length direction of the lower arm bracket. An arc-shaped second through hole 13 is formed on the surface of each second connecting block 8 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 activity block 12 sequentially passes through the first through hole 11 and the second through hole 13 and is threadedly connected with a limiting block 21. A gap is provided between the limiting block 21 and the second connecting block 8, and a spring is sleeved on the outer surface of each activity block 12 and is located between the limiting block 21 and the second connecting block 8.

[0032] As shown in the figure, when the patient's elbow joint is repeatedly bent for exercise, the upper arm remains stationary. When the forearm is bent towards the upper arm, the forearm will simultaneously drive the lower arm bracket and the second connecting block 8 to rotate, causing the second connecting block 8 to rotate around the center of the activity block 12. The second through hole 13 limits the bending amplitude of the lower arm bracket, ensuring the stability of the patient during bending exercise; when the patient's forearm makes a small-range rotational movement around the elbow joint, it will simultaneously drive the lower arm bracket and the second connecting block 8 to rotate around the center of the connecting ring 14. The second connecting block 8 will drive the activity block 12 to make a reciprocating movement along the length direction of the first through hole 11. Among them, since a spring is sleeved on the outer surface of the activity block 12 and is located between the limiting block 21 and the second connecting block 8 (combined with Figure 9As shown in the figure, when the forearm bracket drives the second connecting block 8 to rotate, the gap between the limiting block 21 and the second connecting block 8 facilitates the rotation of the patient's arm (providing sufficient margin for the rotation between the upper arm bracket and the lower arm bracket), and the spring can always abut against the limiting block 21 and the second connecting block 8, so that there is a certain damping when the arm rotates, ensuring the stability of the arm rotation. Of course, the compression amount of the spring can be indirectly adjusted by rotating the limiting block 21 and adjusting the distance from the movable block 12, so as to adjust the rotational damping, which can effectively meet the patient's pursuit of different damping when rotating the arm, and effectively improve the applicable range of the device.

[0033] In this embodiment, a plurality of sleeves 15 are fixedly connected to the inner ring surface of the connecting ring 14 near the outer side of the elbow joint, and each sleeve 15 is arranged at intervals along the circumferential direction of the connecting ring 14. A plurality of connecting sleeves 16 are connected between one end of each sleeve 15 and the outer surface of the adjacent second upper arm bracket 2. A connecting member 17 is disposed through each connecting sleeve 16. The connecting member 17 is cylindrical, and one end of the connecting member 17 away from the connecting sleeve 16 is fixedly connected to the surface of the second lower arm bracket 4. The second air bag 10 is disposed between the elbow joint and the connecting sleeve 16, and the second air bag is fixedly connected to the surfaces of the connecting sleeve 16 and the connecting ring 14.

[0034] As shown in the figure, when the elbow joint bends, the lower arm bracket rotates towards the upper arm bracket. At this time, the second lower arm bracket 4 will drive one end of each connecting member 17 to slide out of the connecting sleeve 16 at the same time, so that one side surface of the second air bag 10 always abuts against the surfaces of the connecting sleeve 16 and the connecting member 17, ensuring that when the elbow joint bends, it will jointly squeeze the second air bag 10 with the connecting member 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 drive all the connecting members 17 to extend or retract into the connecting sleeve 16 at the same time, effectively ensuring that the elbow joint will squeeze the second air bag 10 during movement.

[0035] In this embodiment, fixing plates 18 and guiding air bags 19 which are matched with the shapes of the upper arm bracket, the lower arm bracket and the lower arm extension block 6 are sequentially arranged from the inside to the outside on the inner sides thereof. A air guiding chamber is jointly formed between the surfaces of the lower arm bracket, the upper arm bracket and the lower arm extension block 6 and the corresponding fixing plates 18. Moreover, 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 communicated with the corresponding guiding air bags 19. 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 are formed on the surface of each fixing plate 18. A plurality of air permeable holes 22 which are opposite in position and communicated with each other are formed on the surfaces of each fixing plate 18 and the guiding air bags 19 (combined with Figure 4 andFigure 6 As shown in the figure (not shown in the figure), fans are fixed on the outer surfaces of the upper arm bracket and the lower arm bracket and are connected to their interiors. The air flow blown by the fans enters the air guide chamber and then passes through each ventilation hole 22 to dissipate heat from the arm.

[0036] As shown in the figure, each lower arm extension block 6 and the corresponding fixed plate 18 together form an independent air guide chamber. After the lower arm extension block 6 is fixedly connected to the lower arm bracket, the air guide chambers of the two will also communicate with each other. Through the arrangement of the fixed plate 18 and the guide airbag 19, it is effectively ensured that after the first inflation airbag 9 and the second inflation airbag 10 are squeezed, the gas inside them will be guided to the massage airbag 5 connected to them. Moreover, a plurality of ventilation holes 22 are provided on the surfaces of each guide airbag 19 and the fixed plate 18, so that the air flow blown by the fan into the lower arm bracket and the upper arm bracket can blow towards the patient's arm through the ventilation holes 22 and dissipate heat from the arm, effectively improving the comfort of the patient when wearing this postoperative rehabilitation device.

[0037] In this embodiment, an electric heating plate is provided on the surface of each fixed plate 18 that fits the patient's skin, which is used to adjust the temperature of the surface of the fixed plate 18 and improve the comfort of the patient when using it in winter.

[0038] In this embodiment, the first inflation airbag 9 and the second inflation airbag 10 are respectively connected to an air pump for inflating them (the air pump is not shown in the figure, and its disassembly method can be realized by a buckle or other existing known solutions, which will not be elaborated here). Each air pump is detachably arranged on the surfaces of the corresponding upper arm bracket and lower arm bracket.

[0039] By inflating the first inflation airbag 9 and the second inflation airbag 10 with the air pump, each massage airbag 5 can be actively deformed and inflated, and it is no longer necessary for the patient to bend the arm to achieve arm massage. It is suitable for patients with inconvenient elbow joint bending and can also enjoy the massage function. Of course, for patients who can move the elbow joint, the air pump can also be disassembled to facilitate the patient to move the arm.

[0040] In this embodiment, a plurality of temperature sensors and a plurality of pressure sensors are connected to the surface of each fixed plate 18 that fits the patient's skin. Each temperature sensor, pressure sensor, electric heating plate, fan and air pump are commonly electrically connected to a central controller.

[0041] By means of the central controller, the temperature condition on the surface of the patient's arm is monitored in real time, and the start and stop of the electric heating plate and the fan can be controlled according to a preset program, ensuring that the temperature is appropriate when the patient wears the upper arm bracket and the lower arm bracket, and still enabling the patient to obtain good comfort, reducing the discomfort of the patient. With the pressure sensor, it is convenient for medical staff or operators to correctly wear the upper arm bracket and the lower arm bracket, preventing improper or too tight fixation during wearing, and effectively improving the comfort when the device is used.

[0042] 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 them. 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 to it in form and details without departing from the scope defined by the claims of the present invention.
