Abstract
Description
Technical Field
[0001] This invention relates to the field of postoperative physiotherapy technology, and in particular to an auxiliary physiotherapy device for lower limbs of postoperative patients. Background Technology
[0002] Some hospitalized postoperative patients need to stay in bed for a long time after surgery. This slows down blood flow in the lower limbs and causes lymphatic fluid to accumulate, which can easily lead to deep vein thrombosis and lower limb edema, affecting postoperative recovery. Therefore, the lower limbs of patients are usually massaged and treated after surgery to prevent the above problems from occurring.
[0003] In existing technologies, lower limb pneumatic physiotherapy devices are used to massage and treat patients' lower limbs. These devices use airbags to inflate and deflate, creating compression. However, this method relies solely on inflation and deflation for a single compression action, limiting its effectiveness and making it difficult to precisely target different parts of the patient's lower limbs. This can result in either poor massage or overstimulation. Furthermore, some physiotherapy devices have fixed massage components that cannot be adjusted to accommodate individual differences in limb length, thickness, etc., limiting the massage range and failing to fully cover the areas requiring treatment, thus affecting the overall therapeutic effect. To address these issues, this application proposes an auxiliary lower limb physiotherapy device for postoperative patients. Summary of the Invention
[0004] The purpose of this invention is to address the problem that existing lower limb physiotherapy devices for postoperative patients have limited functionality, and to propose an auxiliary physiotherapy device for postoperative patients' lower limbs.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: A lower limb assistive physiotherapy device for postoperative patients includes an openable and closable sleeve composed of a first arc-shaped plate and a second arc-shaped plate. An airbag is disposed inside the sleeve, and the airbag is composed of two semi-annular airbags, which are respectively disposed on the inner sides of the first arc-shaped plate and the second arc-shaped plate. Massage components are disposed between the inner wall of the first arc-shaped plate and the corresponding semi-annular airbag, and between the inner wall of the second arc-shaped plate and the corresponding semi-annular airbag. The two massage components can form a ring massage component. The massage component is moved by a moving component, and the massage component and the moving component are connected by a rotating component, which can drive the massage component to reciprocate.
[0006] Preferably, at least two sets of airbags are provided, and the length of adjacent airbags joined end to end is equal to the length of the sleeve. The semi-circular airbag is composed of an inner layer and an outer layer, with a cavity between the inner and outer layers. A second air tube is fixedly provided on the outer layer, and the second air tube communicates with the cavity.
[0007] Preferably, the massage assembly includes a massage head, a fixed bracket, and a piston assembly, wherein the piston assembly is fixedly mounted on the fixed bracket, and the massage head reciprocates via the piston assembly.

[0009] Preferably, the massage assembly further includes a fixed air box, which is fixedly connected to the end of the piston cylinder away from the massage head, and the fixed air box is in communication with the inside of the piston cylinder.
[0010] Preferably, a first baffle is provided on the fixed bracket of the massage component corresponding to the first arc plate, and a slot is provided on the first baffle. A second baffle is provided on the fixed bracket of the massage component corresponding to the second arc plate, and a locking block matching the slot is fixedly provided on the second baffle.
[0011] Preferably, the rotating assembly includes a support frame and a movable block, the movable block being fixedly mounted on a fixed support, and the movable block being slidably connected to the support frame.
[0012] Preferably, the rotating assembly further includes a telescopic cylinder, a fixed plate is fixedly mounted on the support frame, one end of the telescopic cylinder is hinged to the fixed plate, and the other end is hinged to the movable block.
[0013] Preferably, the moving component includes a slide rail and a slider, the slider is fixed to the end of the support frame, the slider is slidably disposed inside the slide rail, and the slide rail is fixedly disposed on the outer wall of the sleeve.
[0014] Preferably, the moving component further includes a drive unit, which includes a motor and a lead screw. The lead screw is rotatably disposed within a slide rail and is threadedly connected to a slider. The motor is fixedly disposed on the slide rail, and the output end of the motor is connected to the end of the lead screw for driving the lead screw to rotate.
[0015] Compared with the prior art, the present invention provides a lower limb assistive physiotherapy device for postoperative patients, which has the following beneficial effects.
[0016] This invention uses two semi-annular airbags inside a sleeve to form a complete airbag. When inflated, it can perform annular compression on the patient's lower limbs to achieve the effect of pneumatic physiotherapy, promote blood circulation in the lower limbs, and reduce edema. Through the set massage components, it can perform point massage on the lower limbs, thereby achieving the effect of multiple massage methods. This solves the problem that the existing technology for lower limb physiotherapy equipment for postoperative patients has relatively limited functions.

The massage head moves back and forth under the drive of the piston component, which can simulate the pressing action in manual massage, and focus on different acupoints or muscle groups, effectively making up for the limitations of traditional single airbag compression physiotherapy.
[0020] 5. The present invention, through the set rotating component, can drive the massage head to rotate, so as to achieve the effect of circumferential massage of the lower limbs, and further improve the comprehensiveness and flexibility of the massage.
[0021] 6. This invention, by setting at least two sets of airbags, can perform zoned inflation and deflation operations according to the physiotherapy needs of different parts of the patient's lower limbs, realizing step-by-step pressure or segmented massage, simulating the action of a muscle pump, more effectively promoting venous blood return, and reducing the risk of deep vein thrombosis.

[0037] The present invention will now be described in further detail with reference to the accompanying drawings. The drawings are simplified schematic diagrams, illustrating only the basic structure of the invention, and therefore only show the components relevant to the invention.
[0038] Please refer to Figures 1-14A lower limb assistive physiotherapy device for postoperative patients includes an openable and closable sleeve composed of a first arc-shaped plate 1 and a second arc-shaped plate 2. An airbag is disposed inside the sleeve, and the airbag is composed of two semi-annular airbags. The two semi-annular airbags are respectively disposed on the inner side of the first arc-shaped plate 1 and the second arc-shaped plate 2. Massage components are disposed between the inner wall of the first arc-shaped plate 1 and the corresponding semi-annular airbag, and between the inner wall of the second arc-shaped plate 2 and the corresponding semi-annular airbag. The two massage components can form a ring massage component. The massage component is moved by a moving component. The massage component and the moving component are connected by a rotating component, which can drive the massage component to reciprocate.
[0039] In a specific embodiment of the present invention, the first arc-shaped plate 1 and the second arc-shaped plate 2 are hinged at the same end, and the other ends can be connected or disconnected using bolts and nuts. Specifically, ear plates are fixedly provided on the first arc-shaped plate 1 and the second arc-shaped plate 2, and through holes are opened on the ear plates. When closing the sleeve, the bolt is passed through the corresponding ear plate and the nut is tightened to complete the closure of the sleeve (see Appendix for this state). Figure 1 When it is necessary to place the patient's lower limb into the sleeve, unscrew the bolts and nuts to disconnect the connection between the corresponding ear plates, and then the first arc plate 1 and the second arc plate 2 can be separated, that is, in the open state (see Appendix for this state). Figure 14 ).
[0040] After the sleeve is placed on the patient's lower limb (leg), the two semi-circular airbags can cover the patient's leg. Then, depending on the needs, the patient can choose to press the airbags, press the massage components, or use a combination of airbags and massage components to perform lower limb massage therapy.
[0041] If airbag compression is used, the airbag is inflated by inflating the airbag cavity. The complete airbag, composed of two semi-circular airbags, applies circular compression to the patient's lower limbs and can be repeatedly inflated and deflated to simulate the effect of pressing with a human palm, thus achieving the effect of massage therapy.
[0042] If the massage component is used, the airbag is not inflated, allowing it to deflate naturally. The massage component is then used to massage the patient's lower limbs. Since the airbag is located between the massage component and the patient's lower limbs, it acts as a cushion, preventing the massage component from directly contacting and pressing the patient's lower limbs, thus avoiding pain.
[0043] During operation, the massage component can be moved by the moving component to achieve a push massage effect. In addition, the massage component can be rotated by the rotating component to achieve a full-range massage effect and avoid blind spots.
[0044] If the airbag and massage component are used in combination, the massage component is activated after the airbag is inflated and applies circular pressure to the lower limbs. At this time, the massage component can be used to apply local pressure to the inflated airbag, so that the pressure of the airbag on the lower limbs will change locally, resulting in more precise acupoint stimulation or muscle relaxation effect.
[0045] For example, while the airbag maintains a certain basic pressure, the massage head 4 focuses on pressing acupoints such as Zusanli and Xuehai, further enhancing the therapeutic effect. At the same time, the moving and rotating components can work together to move and rotate the massage head 4 on the surface of the lower limbs compressed by the airbag, realizing the synergistic effect of air pressure compression and mechanical acupressure and rolling massage, effectively solving the limitations of traditional single physiotherapy methods.
[0046] At least two sets of airbags are provided. The length of adjacent airbags connected end to end is equal to the length of the sleeve. The semi-circular airbag is composed of an inner layer 5 and an outer layer 13. There is a cavity between the inner layer 5 and the outer layer 13. A second air tube 14 is fixedly provided on the outer layer 13. The second air tube 14 is connected to the cavity.
[0047] Specifically, since at least two sets of airbags are installed, and the length of adjacent airbags joined end to end is equal to the length of the sleeve, the inflation and deflation sequence and pressure of different sets of airbags can be controlled to achieve zoned pressure application or segmented massage of different parts of the lower limbs. For example, inflation and pressure can be applied sequentially from the ankle to the thigh, and then deflating sequentially from the thigh to the ankle, creating a muscle pump-like effect that promotes venous blood and lymphatic return, effectively preventing deep vein thrombosis and lower limb edema.
[0048] The other end of the second air tube 14 is connected to an air pump device, which is used to inflate or deflate the air. For example, two sets of air pump devices can be used, one for inflating and one for deflating. Correspondingly, one semi-circular airbag corresponds to two second air tubes 14, and these two second air tubes 14 correspond to two sets of air pump devices respectively.
[0049] In this design, both the inner layer 5 and the outer layer 13 are made of elastic materials, such as rubber. The inner layer 5 is more elastic than the outer layer 13, meaning that after inflation, the inner layer 5 deforms more than the outer layer 13. This design allows the inner layer 5 to make full contact with the lower limbs after inflation. The outer layer 13 is also elastic so that the massage component can achieve the normal pressing effect when used alone. If the outer layer 13 is not elastic, the massage component will be blocked by the outer layer 13, thus preventing the massage component from performing its massage function.
[0050] Specifically, in this solution, the upper semi-circular airbag corresponding to the first arc-shaped plate 1 is fixedly connected to the top of the first arc-shaped plate 1 through the corresponding fixing bracket 6, and the lower semi-circular airbag is fixedly connected to the bottom of the first arc-shaped plate 1 through the corresponding fixing bracket 6; the upper semi-circular airbag corresponding to the second arc-shaped plate 2 is fixedly connected to the top of the second arc-shaped plate 2 through the corresponding fixing bracket 6, and the lower semi-circular airbag is fixedly connected to the bottom of the second arc-shaped plate 2 through the corresponding fixing bracket 6.
[0051] The massage assembly includes a massage head 4, a fixed bracket, and a piston assembly. The piston assembly is fixedly mounted on the fixed bracket, and the massage head 4 reciprocates through the piston assembly.
[0052] Specifically, the fixed support includes a bracket 3 and a connecting plate 20. There are three brackets 3, and adjacent brackets 3 are fixedly connected by the connecting plate 20. Each bracket 3 is equipped with several piston assemblies. For example, in this solution, there are three brackets 3 in one fixed support, and each bracket 3 is equipped with seven piston assemblies. This arrangement can increase the range of the massage assembly during pressing. In use, the piston assembly drives the massage head 4 to extend and retract to achieve the pressing effect.
[0053] The piston assembly includes a piston cylinder 19 and a piston rod 18. The piston cylinder 19 is fixedly mounted on a fixed bracket, and the piston rod 18 is slidably connected to the piston cylinder 19. The massage head 4 is fixedly mounted on the outer end of the piston rod 18.
[0054] Specifically, the piston cylinder 19 is fixedly mounted on the bracket 3. The piston end of the piston rod 18 is located inside the piston cylinder 19, and the non-piston end is located outside the piston cylinder 19. When in use, air is injected or de-inflated into the piston cylinder 19 to drive the piston rod 18 to move, which in turn drives the massage head 4 to move, thus achieving the pressing effect of the massage head 4.
[0055] The massage assembly also includes a fixed air box 8, which is fixedly connected to the end of the piston cylinder 19 away from the massage head 4, and the fixed air box 8 is in communication with the inside of the piston cylinder 19.
[0056] Specifically, the number of fixed air boxes 8 corresponds to the number of brackets 3. Adjacent fixed air boxes 8 are connected by connecting pipes 22, and one of the fixed air boxes 8 is provided with a connector 27. The connector 27 is connected to the fixed air box 8 and is connected to the air pump device through the first air pipe 11. The specific arrangement can refer to the connection between the air bag and the air pump device to realize the inflation or deflation of the fixed air boxes 8. When inflating, the gas can enter each fixed air box 8 and then enter each piston cylinder 19, thereby pushing the piston rod 18 to extend, so that the massage head 4 presses the lower limb. After deflating, the gas in each fixed air box 8 is drawn away. At the same time, the gas in the piston cylinder 19 is also drawn away. Under the action of air pressure, the piston rod 18 retracts, thereby driving the massage head 4 away from the patient's lower limb. This cycle is repeated to achieve the effect of point massage. It should be noted that the massage component is designed to adaptively adjust the distance each massage head 4 moves according to the shape of the lower limb during inflation and pressing, ensuring that each massage head 4 effectively contacts the lower limb and applies the same pressure to the lower limb. Since the distance between different parts of the lower limb and the corresponding massage head 4 varies, if each massage head 4 extends the same distance, it will inevitably cause local over-pressing or local neglect. In this solution, after inflation, if a massage head 4 contacts the lower limb first, it will be blocked by the lower limb and will not continue to move. The air pressure will be distributed to the piston cylinder 19 corresponding to other massage heads 4, allowing the other massage heads 4 to continue moving until they contact the lower limb. Once all massage heads 4 have contacted the lower limb, continued pressure will ensure that all massage heads 4 press the lower limb, effectively avoiding the problems of local over-pressing or local neglect.
[0057] A first baffle 24 is provided on the fixed bracket of the massage component corresponding to the first arc plate 1, and a slot 25 is provided on the first baffle 24. A second baffle 29 is provided on the fixed bracket of the massage component corresponding to the second arc plate 2, and a locking block 30 matching the slot 25 is fixedly provided on the second baffle 29.
[0058] Specifically, the first baffle 24 is fixedly installed at the end of the corresponding bracket 3, and the bracket 3 has a first baffle 24 at both ends; the second baffle 29 is fixedly installed at the end of the corresponding bracket 3, and the bracket 3 has a second baffle 29 at both ends; in use, after the first arc plate 1 and the second arc plate 2 are closed, the first baffle 24 can fit with the corresponding second baffle 29, and the locking block 30 can be locked in the corresponding slot 25, so that the brackets 3 in the two massage components together form a ring-shaped bracket 3. With this configuration, when the moving component and the rotating component drive one set of massage components to move or rotate, they can also drive the other set of massage components to move or rotate, thus reducing the number of moving components and rotating components.
[0059] The rotating assembly includes a support frame 9 and a movable block 10. The movable block 10 is fixedly mounted on the fixed support, and the movable block 10 and the support frame 9 are slidably connected.
[0060] Specifically, the movable block 10 is fixedly mounted on the corresponding bracket 3. The support frame 9 is arc-shaped, and the movable block 10 can move in an arc along the support frame 9, thereby driving the massage component to rotate.
[0061] The rotating assembly also includes a telescopic cylinder 12, and a fixed plate 15 is fixedly installed on the support frame 9. One end of the telescopic cylinder 12 is hinged to the fixed plate 15, and the other end is hinged to the movable block 10.
[0062] Specifically, a first fixed post 21 is fixedly installed on the movable block 10, and a second fixed post 28 is fixedly installed on the fixed plate 15. The telescopic end of the telescopic cylinder 12 is hinged to the first fixed post 21, and the non-telescopic end of the telescopic cylinder 12 is hinged to the second fixed post 28. In use, the telescopic cylinder 12 drives the movable block 10 to move along the support frame 9, thereby driving the massage component to rotate. In this solution, there is one telescopic cylinder 12, and the telescopic cylinder 12 drives the massage component on the corresponding first arc plate 1 to rotate actively, while the massage component on the corresponding second arc plate 2 rotates passively.
[0063] The moving component includes a slide rail 16 and a slider 23. The slider 23 is fixed to the end of the support frame 9 and is slidably disposed inside the slide rail 16. The slide rail 16 is fixedly disposed on the outer wall of the sleeve.
[0064] Specifically, in this scheme, there are four slide rails 16 in total. Two slide rails 16 are provided on the first arc plate 1 and the second arc plate 2 respectively. Slider 23 is fixedly provided at both ends of each support frame 9. The two sliders 23 on the support frame 9 corresponding to the first arc plate 1 are slidably arranged on the two slide rails 16 on the corresponding first arc plate 1 respectively. The two sliders 23 on the support frame 9 corresponding to the second arc plate 2 are slidably arranged on the two slide rails 16 on the corresponding second arc plate 2 respectively.
[0065] The moving component also includes a drive unit, which includes a motor 7 and a lead screw 17. The lead screw 17 is rotatably disposed within the slide rail 16 and is threadedly connected to the slider 23. The motor 7 is fixedly disposed on the slide rail 16, and the output end of the motor 7 is connected to the end of the lead screw 17 for driving the lead screw 17 to rotate.
[0066] Specifically, in this design, a lead screw 17 is provided, which is rotatably mounted in one of the slide rails 16 on the first arc plate 1. A slide rod 26 is fixedly mounted in the other slide rail 16 on the first arc plate 1. Corresponding to the two sliders 23 of the support frame 9 of the first arc plate 1, one slider 23 is threadedly connected to the lead screw 17, and the other slider 23 is slidably connected to the slide rod 26. Slide rods 26 are fixedly mounted in both slide rails 16 on the second arc plate 2. The two sliders 23 of the support frame 9 of the second arc plate 2 are slidably connected to the corresponding slide rods 26. The motor 7 is a servo motor. The motor 7 is fixedly mounted on the slide rail 1. On the outside of the slide rail 16, which has a lead screw 17 inside, a drive synchronous pulley is fixedly installed on the output shaft of the motor 7, and a driven synchronous pulley is fixedly installed at the top of the lead screw 17. The drive synchronous pulley and the driven synchronous pulley are connected by a synchronous belt. In use, the motor 7 drives the lead screw 17 to rotate. Since the corresponding slider 23 is threadedly connected to the lead screw 17, the slider 23 can move within the slide rail 16, thereby driving the support frame 9 to move, and then driving the corresponding massage component to move. When the massage component moves, it can drive another set of massage components to move, thus achieving the effect of the moving component driving the massage component to move.
[0067] Workflow: First, medical staff selects an appropriate physiotherapy mode based on the patient's specific lower limb condition. If the airbag compression mode is selected, the sleeve is opened, and the patient is assisted in placing their lower limb inside the sleeve. Then, the sleeve is closed, and the ear plates on the sleeve are secured with bolts and nuts to prevent the sleeve from opening. Next, the air pump is activated, inflating the semi-circular airbag cavity through the second air tube 14. This causes the airbag to expand, and the two semi-circular airbags form a complete airbag that performs circular compression on the patient's lower limb. The air pump is then controlled to repeatedly inflate and deflate, simulating the effect of hand pressure. When it is necessary to apply pressure to different areas or perform segmented massage, the inflation and deflation sequence and pressure of different groups of airbags are controlled, such as inflating and pressurizing sequentially from the ankle to the thigh, and then deflating sequentially from the thigh to the ankle.
[0068] If the massage component is selected in the pressing mode, the patient's lower limb is first placed into the closed sleeve. At this time, the airbag is not inflated, allowing it to naturally deflate. The air pump connected to the fixed air box 8 is activated, and air is inflated into the fixed air box 8 through the first air pipe 11. The gas enters each piston cylinder 19, pushing the piston rod 18 to extend, thereby driving the massage head 4 to perform point massage on the lower limb. Since the airbag is located between the massage component and the patient's lower limb, the airbag can act as a cushion, preventing the massage head 4 from directly contacting and causing pain. At the same time, the moving component and the rotating component can be activated. The motor 7 in the moving component drives the lead screw 17 to rotate, causing the slider 23 to move within the slide rail 16, thereby driving the support frame 9 and the massage component to reciprocate, realizing push massage. The telescopic cylinder 12 in the rotating component extends and retracts, causing the movable block 10 to slide along the arc-shaped support frame 9, making the massage component rotate, realizing all-round massage and avoiding dead angles.
[0069] If you choose the combination of airbag and massage component, first inflate the airbag using the airbag pressing mode to maintain a certain basic pressure and perform circular compression on the lower limbs; then activate the massage component. At this time, the massage head 4, driven by the moving or rotating component, applies local pressure to the inflated airbag; for example, the massage head 4 can focus on pressing acupoints such as Zusanli and Xuehai, creating a more precise acupoint stimulation or muscle relaxation effect based on the airbag compression, achieving the synergistic effect of air pressure compression and mechanical acupressure and rolling massage.
[0070] Throughout the physiotherapy process, medical staff can adjust parameters such as the air pump pressure, massage component pressure, and movement speed of the moving and rotating components based on the patient's feedback and tolerance to achieve the best therapeutic effect. After the physiotherapy, the operation of the relevant equipment is stopped first, then the bolts and nuts are unscrewed, the sleeve is opened, and the patient is assisted in removing their lower limbs.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
