Abstract

This invention relates to the field of medical rehabilitation equipment technology, specifically to a lower limb functional recovery rehabilitation device. It includes: a base; a housing located on the upper end of the base; and several training mechanisms evenly distributed within the housing along an outer trajectory line. Each training mechanism can be inflated to extend from within the housing, forming an obstacle for obstacle training when the patient walks around the perimeter of the housing. Through the arrangement of these training mechanisms, during lower limb functional rehabilitation training, inflation causes the inflatable components to extend from the housing, forming obstacles that the patient must step over or around when walking around the housing, thus achieving the desired training effect on the patient's walking ability or body coordination.

Description

Technical Field

[0001] This invention relates to the field of medical rehabilitation equipment technology, specifically to a lower limb functional recovery rehabilitation device. Background Technology

[0002] In medical rehabilitation, functional rehabilitation training for patients' limbs is an important means of restoring their daily mobility, such as enabling them to regain independent walking, hand-eye coordination, and overall limb function.

[0003] In the early stages of rehabilitation training, in order to avoid secondary injuries due to accidents, corresponding human companions or corresponding training equipment are often used for rehabilitation training. However, the former consumes a lot of manpower, and one-on-one companionship requires a lot of manpower. The latter has high requirements for the venue, and general training equipment is only a simple structure such as a balance beam or stairs, which is not very effective for the overall recovery of the patient's limb ability. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention proposes a lower limb functional recovery and rehabilitation device to solve the technical problems of existing technologies, such as difficulty in adapting to the needs of patients with different conditions and limited functionality.

[0005] The technical solution adopted in this invention is a lower limb functional recovery and rehabilitation device, comprising: Base; The housing is located at the top of the base; The training facilities are several in number and are evenly distributed within the box along the outer track line of the box. The training mechanism can be inflated to extend from the box and form an obstacle barrier, used for obstacle training when patients walk around the perimeter of the box.

[0006] This structure allows for the flexible setting of walking obstacles to create a training environment for patients during lower limb functional rehabilitation training, and can also be used in smaller spaces and indoors.

[0007] The base is a hydraulic scissor lift, which can drive the entire box to move up and down vertically.

[0008] This structure allows for adjustments to the overall height of the training facility to suit the current training environment or meet the needs of different patients, offering greater flexibility.

[0009] The training mechanism includes: a support fixedly installed inside the box, an air cylinder installed at the upper end of the support, an air pump connected to the air circuit inside the air cylinder, and an expansion member installed on the air cylinder and connected to its air circuit. The air pump can input air into the air cylinder through an electrically controlled valve and cause the expansion member to expand and extend away from the box. The expansion member can contract itself and expel internal air through an electrically controlled valve when at rest.

[0010] This structure uses an air pump to inflate the air cylinder, which in turn inflates the expansion component. This obstacle setting is simple, meets the needs of obstacle setting, and will not obstruct or harm patients when they walk or collide with it. It can also automatically reset when stepped on or bent by patients, without being directly damaged, and has a longer service life.

[0011] The air cylinder is equipped with a winding assembly, which can wind up and pull the expansion component to one side of the air cylinder when the expansion component deflates. The winding assembly includes: a winding roller rotatably disposed inside the air cylinder, a spring spring disposed outside the air cylinder and connected to the winding roller for transmission, and a traction cable wound around the winding roller and the end of the expansion member, wherein the axial direction of the winding roller is perpendicular to the expansion and extension direction of the expansion member.

[0012] This structure allows for more effective winding and resetting of the expansion component during deflation and resetting, reducing the overall volume and exposed structure of the device when it is stored.

[0013] The support is equipped with a positioner, which can limit the extension length of the expansion member; The positioner includes: a gear rotatably disposed on the outside of the air cylinder and coaxially connected to the take-up roller; a driven wheel rotatably disposed on the outside of the air cylinder and meshing with the gear; a screw concentrically connected to the driven wheel; a movable head threadedly connected to the screw and slidingly abutting against the lower end of the air cylinder; and an abutting member disposed on the lower side of the support. The diameter of the gear is smaller than the diameter of the driven wheel, and the stroke of the movable head moving after the driven wheel drives the screw is positively correlated with the expansion stroke of the expansion member. The abutting member can extend and retract and form an abutting limit on the lower end of the movable head.

[0014] This structure, through the synchronous winding assembly of the take-up roller and the synchronous extension and retraction stroke of the expander, allows the expansion length of the expander to be set as needed when inflating it, in order to further meet the needs of rehabilitation training in different scenarios.

[0015] The box is equipped with a transmission mechanism, and several training mechanisms are mounted on the transmission mechanism. The transmission mechanism can drive several training mechanisms to move synchronously along the trajectory line on the outer side of the box. The transmission mechanism includes: a motor located on the lower side of the housing, two transmission wheels symmetrically distributed inside the housing along the length of the housing, and an accessory chain wound between the two transmission wheels. Several training mechanisms are located on the accessory chain, and the output shaft of the motor is connected to one of the transmission wheels.

[0016] This structure allows several training units to move autonomously along the trajectory line of the outer wall of the box, enabling patients to stand in place or cooperate with a walking structure like a treadmill, further meeting the needs of patients in different states and with different usage requirements.

[0017] The inner sidewall of the box is provided with a conductive component corresponding to the support, and the conductive component is used to provide power to the training mechanism and the positioner. The conductive component includes: a conductive groove disposed on the inner wall of the box and matching the side trajectory of the inner wall of the box, and a conductive post disposed at the lower end of the support and slidingly abutting against the conductive groove.

[0018] This structure allows the training mechanism to control the inflation and deflation at any position within the chamber, improving the control flexibility of the training mechanism.

[0019] The housing includes: a lower housing connected to the base, a central column located in the middle of the lower housing, and an upper housing connected to the central column, with a gap between the lower housing and the upper housing to accommodate the training mechanism. The gap is provided with a shielding cloth strip, which is connected to several training mechanisms and completely covers the opening of the gap.

[0020] This structure can meet both the needs of the training institution for relocation and the needs of equipment maintenance in the later stages.

[0021] As can be seen from the above technical solution, the beneficial technical effects of the present invention are as follows: 1. By setting up the training institution, when patients are undergoing lower limb functional rehabilitation training, the expansion component can be inflated to extend out of the box to form an obstacle, so that the patient needs to step over or go around the expansion component when walking around the box, thereby meeting the needs of training the patient's walking ability or body coordination ability.

[0022] 2. By setting up the winding component, the expansion component can be actively wound up after it deflates, improving the overall storage effect of the device.

[0023] 3. By setting the positioner, it can coordinate with the contraction of the storage component and the expansion component, and limit the extension length of the expansion component as needed, further meeting the usage requirements of the extension length of the expansion component in different scenarios.

[0024] 4. Through the setting of the transmission mechanism, it can drive several training mechanisms to move along the box as needed, thereby meeting the needs of some patients who need to train in place or use in conjunction with a treadmill. Attached Figure Description

Detailed Implementation

[0028] The embodiments of the technical solution of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the technical solution of the present invention and are therefore intended to limit the scope of protection of the present invention.

[0029] It should be noted that, unless otherwise stated, the technical or scientific terms used in this application should have the ordinary meaning as understood by one of ordinary skill in the art to which this invention pertains.

[0030] Example 1: like Figure 1-5As shown, this embodiment provides a lower limb functional recovery rehabilitation device, including: a base 1, a box 2, and a training mechanism 3; the box 2 is located on the upper end of the base 1; the number of training mechanisms 3 is several and they are evenly distributed at intervals along the outer trajectory line of the box 2 inside the box 2; the training mechanism 3 can be inflated to extend out of the box 2 to form an obstacle, which is used for obstacle training when the patient walks around the perimeter of the box 2.

[0031] In this embodiment, the base 1 is a hydraulic scissor lift frame, which can drive the entire box 2 to move up and down in the vertical direction. This can meet the needs of different patients for adjustment and use, and in some exercise scenarios, it can also exercise different limbs of the patient, such as the whole body and head.

[0032] The working principle of Example 1 is explained in detail below: When patients undergo lower limb functional rehabilitation, the box 2 is first adjusted to a suitable height according to the patient's height or optimal usage condition. Then, the patient can walk independently along the length of the box 2 or walk while holding onto the box 2, depending on their own condition. Of course, handrails or other structures or devices can be appropriately installed at the upper end of the box 2 to help the patient stabilize their body. During walking, the training mechanism 3 will inflate and extend, thus obstructing the patient's walking path. As a result, the patient needs to lift their feet to step over or around the obstacle created by the training mechanism 3, thereby providing the patient with walking rehabilitation training under the coordination of the whole body. In particular, when the patient crosses the obstacle, it can effectively train the patient's lower limb function. Compared with simply walking or moving joints, this method of lower limb function recovery is more effective.

[0033] During the patient's training, they can walk around the trajectory line on the outer side of the box 2 in a loop. This allows them to achieve the same training and rehabilitation effect in a smaller space, such as indoors, without the need for a large space or venue for walking training. The environment for rehabilitation exercise is safer.

[0034] Training mechanism 3 includes: a support 31 fixedly installed inside the housing 2, an air cylinder 32 installed at the upper end of the support 31, an air pump 33 connected to the air passage inside the air cylinder 32, and an expansion member 34 installed on the air cylinder 32 and connected to its air passage. The air pump 33 can input air into the air cylinder 32 through an electrically controlled valve and cause the expansion member 34 to expand and extend away from the housing 2. When stationary, the expansion member 34 can contract on its own and expel internal air through an electronically controlled valve.

[0035] In this first embodiment, the expansion member 34 is mainly made of rubber and has the properties of expansion and contraction, such as the balloon-like structure in the prior art. When the expansion member 34 is inflated, it will extend away from the box 2 to form a structural barrier. However, since the expansion member 34 itself does not have a rigid barrier feature, when the patient collides with or steps on the expansion member 34, it will not affect the stability of the expansion member 34 or the patient's walking. On the one hand, it can improve the service life and scene adaptability of the training equipment, and on the other hand, it can improve the safety of the patient during rehabilitation training and avoid falling due to instability when stepping on a hard structure.

[0036] In addition, in some other embodiments, the expansion member 34 is provided with an elastic corrugated cover, which can guide the expansion direction of the expansion member 34 without affecting the mobility of the expansion member 34 itself during training. It can also achieve a more effective folding and storage effect by the expansion member 34 itself contracting or by manual active contraction during storage.

[0037] When the expansion component 34 is started, it is mainly activated by the air pump 33, which introduces external air into the air cylinder 32 through the electronically controlled valve. Positive pressure is formed in the air cylinder 32, which causes the expansion component 34 to inflate and extend. When deflating and resetting, the electronically controlled valve opens and the air pump 33 closes, and the air is automatically released. The expansion component 34 that has completely released the air can remain in a contracted state. The expansion component 34 that has not completely deflated will also remain in a drooping state that fits against the box 2 due to the loss of the supporting force after inflation and expansion. This is more conducive to the storage of the device.

[0038] In order to control the opening and closing of the training unit 3, each training unit 3 is equipped with a Bluetooth module and a control module. Nursing staff can send commands to the Bluetooth module through an external control panel or such as a mobile phone or computer, and the control module will execute them, thereby achieving the effect of independent control or centralized control of several training units 3.

[0039] Example 2: like Figure 3-5 As shown, the only difference in technical features compared with Embodiment 1 is that the air cylinder 32 is provided with a winding assembly 4, which can wind up and pull the expansion member 34 to one side of the air cylinder 32 when the expansion member 34 is deflated. The winding assembly 4 includes: a winding roller 41 rotatably disposed inside the air cylinder 32, a spring spring 42 disposed outside the air cylinder 32 and connected to the winding roller 41 for transmission, and a traction cable 43 wound around the winding roller 41 and the end of the expansion member 34. The axial direction of the winding roller 41 is perpendicular to the expansion and extension direction of the expansion member 34.

[0040] Apart from that, all other structures are identical.

[0041] In this second embodiment, in order to further improve the storage effect of the expansion member 34, in the uninflated state, the winding roller 41 is pulled by the winding action of the spring 42, and the traction cable 43 will pull the expansion member 34 to form a folding and winding effect. This allows the end of the expansion member 34 to retract and embed itself, forming a folded loop state, thereby achieving a storage effect in a smaller space. In addition, the pulling of the expansion member 34 by the traction cable 43 can also form an active air release effect.

[0042] Example 3: like Figure 3-5 As shown, the only difference in technical features compared to Embodiment 2 is that the support 31 is provided with a positioner 5, which can limit the extension length of the expansion member 34. The positioner 5 includes: a gear 51 rotatably disposed on the outside of the air cylinder 32 and coaxially connected to the take-up roller 41; a driven wheel 52 rotatably disposed on the outside of the air cylinder 32 and meshing with the gear 51; a screw 53 coaxially connected to the driven wheel 52; a movable head 54 threadedly connected to the screw 53 and slidingly abutting against the lower end of the air cylinder 32; and an abutting member 55 disposed on the lower side of the support 31. The diameter of the gear 51 is smaller than the diameter of the driven wheel 52, and the stroke of the movable head 54 after the driven wheel 52 drives the screw 53 is positively correlated with the expansion stroke of the expansion member 34. The abutting member 55 can extend and retract and form an abutting limit on the lower end of the movable head 54.

[0043] Apart from that, all other structures are identical.

[0044] In this third embodiment, when it is necessary to limit the extension length of the inflator 34 to change the extension length of the obstacle and achieve different training effects, this can be achieved by detecting the movement position of the movable head 54 and through the abutment member 55. When the inflator 34 is inflated, its extension will cause the take-up roller 41 to rotate via the traction cable 43. At this time, the rotation of the take-up roller 41 will drive the external gear 51 to rotate, and the gear 51 and the driven wheel 52 will mesh, so the driven wheel 52 will also rotate synchronously, causing the screw 53 connected to it to rotate. When the movable head 54 is subjected to When the screw 53 is driven to rotate and is blocked by the air cylinder 32, the piston head 54 will move along the axial direction of the screw 53. At this time, the movement stroke position of the piston head 54 can be detected by a position sensor until it reaches the predetermined extension length position of the corresponding expansion member 34. At this time, the abutment member 55 is activated to form an abutment limit on the piston head 54. In this way, the expansion member 34 will no longer extend when continuously inflated, but will instead expand. At this time, the air pump 33 is turned off. Of course, in order to prevent the expansion member 34 from bursting accidentally during continuous inflation, a pressure relief valve can be set on the air cylinder 32 to reduce the excessive air pressure inside the air cylinder 32.

[0045] By limiting the position of the movable head 54, the extension length of the expansion member 34 can be restricted to meet the needs of different training and rehabilitation scenarios. When the expansion member 34 is reset, the spring 42 drives the winding roller 41 to reset, thereby driving the expansion member 34 and the gear 51. The movable head 54 can also be reset under the drive of the driven wheel 52 to the screw 53 to meet the needs of the next inflation.

[0046] In this embodiment, the abutting member 55 includes a rubber strip and an electrically controlled telescopic rod. The rubber strip is connected to the telescopic shaft of the electrically controlled telescopic rod. The length direction of the rubber strip is the same as the axial direction of the screw 53. Thus, by pushing the rubber strip with the electrically controlled telescopic rod, the rubber strip can be used to abut and limit the movable head 54.

[0047] Example 4: like Figure 1-3 As shown in Figure 5, the only difference in technical features compared with Embodiment 1 is that the box 2 is provided with a transmission mechanism 6, and several training mechanisms 3 are all provided on the transmission mechanism 6. The transmission mechanism 6 can drive several training mechanisms 3 to move synchronously along the trajectory line of the outer side of the box 2. The transmission mechanism 6 includes: a motor 61 located on the lower side of the outer side of the housing 2, two transmission wheels 62 symmetrically distributed inside the housing 2 along the length of the housing 2, and an accessory chain 63 wound between the two transmission wheels 62. Several training mechanisms 3 are all located on the accessory chain 63. The output shaft of the motor 61 is connected to one of the transmission wheels 62.

[0048] Apart from that, all other structures are identical.

[0049] In this fourth embodiment, in order to further improve the training effect in different scenarios, such as when the patient uses the treadmill 8, or when the patient only needs to stand in place, the corresponding transmission wheel 62 can be started by the motor 61. At this time, the transmission wheel 62 rotates and through the accessory chain 63 and another transmission wheel 62, it forms the effect of driving several training mechanisms 3 to circulate. In this way, after the expansion member 34 is inflated, it can move accordingly, and the flexibility is higher.

[0050] The inner wall of the housing 2 is provided with a conductive component 7 corresponding to the support 31. The conductive component 7 is used to provide power to the training mechanism 3 and the positioner 5. The conductive component 7 includes: a conductive groove 71 disposed on the inner wall of the housing 2 and matching the side trajectory of the inner wall of the housing 2, and a conductive post 72 disposed at the lower end of the support 31 and slidingly abutting against the conductive groove 71.

[0051] In this fourth embodiment, the conductive component 7 can meet the power supply needs of the electrical devices in the training mechanism 3 and the locator 5, and can retract the expansion member 34 in areas of the housing 2 where there is no interaction with the patient, such as the opposite side of the treadmill 8, to avoid collision with the external structure, thereby improving the flexibility of the device.

[0052] The housing 2 includes: a lower housing 21 connected to the base 1, a central column 22 located in the middle of the lower housing 21, and an upper housing 23 connected to the central column 22. A gap is provided between the lower housing 21 and the upper housing 23 to accommodate the training mechanism 3. A shielding strip 24 is provided in the gap, which is connected to several training mechanisms 3 and completely covers the opening of the gap.

[0053] In this fourth embodiment, the upper box 23 and the lower box 21 are connected by a central column 22. When necessary, the upper box 23 can be removed to maintain other components in the lower box 21. The shielding cloth 24 can cover the gap between the upper box 23 and the lower box 21 without affecting the movement of the training mechanism 3, so as to prevent external impurities or patients from accidentally entering.

[0054] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention, and they should all be covered within the scope of the claims and specification of the present invention.
