DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0027] The following is combined with Figure 1-Figure 4 The specific implementation modes of the present invention are described in further detail.

[0028] Depend on Figure 1-Figure 4 As shown, the present invention includes a fixed bracket 1. In order to reduce the probability of foot drop in patients, a contact pad 2 is detachably connected to the upper side of the fixed bracket 1. A plurality of physiotherapy airbags 3 that can be alternately inflated and deflated are arranged between the fixed bracket 1 and the contact pad 2. A rotating bracket 4 is fixedly connected to the left and right sides of the front part of the fixed bracket 1 respectively. A rotatable support frame 5 for supporting the foot is arranged on the front side of the fixed bracket 1. Each rotating bracket 4 is rotatably connected to the support frame 5. A first support pad 6 for supporting the patient's popliteal fossa is arranged in the middle part of the upper side of the contact pad 2. A slope pad 7 fixedly connected to the contact pad 2 is arranged on the front side of the first support pad 6. A second support pad 8 for supporting the patient's calf is arranged on the front side of the upper part of the contact pad 2.

[0029] When in use, the fixed bracket 1 can be directly placed on the patient's bed, and then the patient's legs can be placed on the upper side of the contact pad 2, so that the first support pad 6 corresponds to the patient's popliteal fossa (back of the knee) position, and the patient's knee position is raised and supported. At this time, the patient's calf is located between the first support pad 6 and the second support pad 8. The second support pad 8 is used to support the distal end of the patient's gastrocnemius muscle, which can be more ergonomic and increase the contact area between the patient's legs and the contact pad 2, the first support pad 6 and the second support pad 8, thereby reducing the probability of pressure sores on the patient's legs. At this time, the support frame 5 can support the patient's feet, thereby preventing or correcting the patient's foot drop symptoms through physical therapy;

[0030] In order to adapt to patients with different leg lengths, the front and rear positions of the first support pad 6 relative to the fixed bracket 1 can be adjusted to adapt to patients with different calf lengths. After the position of the first support pad 6 is adjusted, the inclined pad 7 is used to support the distal end of the popliteal fossa;

[0031] When pneumatic physiotherapy is needed for the patient's legs, multiple physiotherapy airbags 3 can be inflated and deflated in sequence from the distal end to the proximal end. The external pressurization of the physiotherapy airbags 3 can promote the return of venous blood and lymph in the patient's lower limbs, thereby preventing deep vein thrombosis in the lower limbs and reducing swelling of the lower limbs.

[0032] Further, by Figure 1-Figure 4 As shown, in order to assist the patient in performing ankle pump exercises, a clearance groove 9 is provided on the side of each rotating bracket 4 away from the fixed bracket 1, and a rotating pin 10 is fixedly connected to the middle of the clearance groove 9. The left and right sides of the support frame 5 are respectively rotatably connected to the corresponding rotating pins 10, and a foot support pad 11 is detachably connected to the rear side of the support frame 5; the axial direction of the rotating pin 10 corresponds to the rotation position of the patient's ankle joint, so that the support frame 5 can better fit the patient's foot when rotating, reducing the relative sliding of the patient's foot and the foot support pad 11;

[0033] Further, by Figure 1-Figure 4 As shown, in order to fix the patient's foot, the cross-section of the foot support pad 11 is concave, the front side of the foot support pad 11 is detachably connected to the support frame 5 through Velcro, and the rear side of the foot support pad 11 is provided with a fixing belt 12 for fixing the foot;

[0034] During use, when performing lower limb rehabilitation therapy on different patients, the foot support pad 11 can be disassembled and replaced through Velcro, reducing the risk of cross-infection when different patients use the device. The concave cross-sectional design of the foot support pad 11 can reduce the probability of the patient's foot slipping off the left and right sides of the foot support pad 11.

[0035] Further, by Figure 1 Figure 4 As shown, in order to reduce the probability of pressure sores on the patient's feet, the fixing belt 12 includes an elastic belt 13 and an adhesive block 14, the elastic belt 13 is Y-shaped, each adhesive block 14 is fixedly connected to the end of the elastic belt 13, and each adhesive block 14 is detachably connected to the left and right sides of the foot support pad 11 through Velcro;

[0036] It should be noted that the elastic band 13 and the adhesive block 14 are both fixedly connected to a medical sponge on one side close to the patient's foot, so as to reduce the pressure sores on the patient's back;

[0037] When in use, the patient's foot can be simply fixed by the Y-shaped elastic band 13, so that the patient can perform ankle pump movements as the angle of the support frame 5 changes. When the patient's foot is fixed for a long time, the contact position between the fixation band 12 and the patient's foot can be changed by adjusting the direction of the elastic band 13 or moving the position of the fixation band 12 upward or downward, thereby reducing the risk of pressure sores on the dorsum of the patient's foot.

[0038] Further, by Figure 1-Figure 4 As shown, in order to perform ankle pump exercise therapy at a larger angle on the patient's foot, a sliding groove 15 is provided at the lower part of the support frame 5, a sliding block 16 is slidably connected inside the sliding groove 15, a telescopic rod 17 that can move forward and backward is provided inside the fixed bracket 1, a rotating groove 18 is provided on the front side of the telescopic rod 17, a rotating block 19 is fixedly connected to the rear side of the sliding block 16, the rotating groove 18 is rotatably connected to the rotating block 19, and the telescopic rod 17 moves forward and backward relative to the fixed bracket 1 to form a structure for adjusting the angle of the support frame 5;

[0039] It should be noted that the rotating block 19 is located at a relatively lower position behind the sliding block 16. When the telescopic rod 17 is extended forward a long distance, the lower part of the sliding block 16 is protruded from the lower part of the sliding groove 15, while the upper part of the sliding block 16 is still slidably connected to the sliding groove 15.

[0040] During use, when the telescopic rod 17 moves forward, it will drive the lower part of the sliding block 16 to move forward under the action of the rotating groove 18 and the rotating block 19, thereby driving the support frame 5 to rotate, and driving the patient's toes to flex backward. Since the support frame 5 can only rotate around the rotating bracket 4, the sliding block 16 will move downward relative to the support frame 5. Similarly, when the telescopic rod 17 moves backward, it will drive the support frame 5 to rotate in the opposite direction, and at this time, the patient's toes will be stretched forward, performing a reciprocating motion of the ankle pump.

[0041] Further, by Figure 1-Figure 4As shown, in order to facilitate the operation of medical staff, a motor 20 is fixedly connected inside the fixed bracket 1, a threaded rod 21 is fixedly connected to the output end of the motor 20, a threaded block 22 is threadedly connected to the middle of the threaded rod 21, and the upper side of the threaded block 22 is fixedly connected to the telescopic rod 17;

[0042] It should be noted that the motor 20 is a servo motor 20, which is a prior art and can be reciprocated by a built-in controller, thereby driving the support frame 5 to rotate forward and backward, which need not be described in detail here; two adjustment buttons are provided on the front side of the support frame 5, and by pressing the adjustment buttons, the motor 20 can be started to adjust the angle of the support frame 5 or make the motor 20 rotate forward and reverse within a certain range;

[0043] When in use, after the motor 20 is started, the motor 20 drives the threaded rod 21 to rotate, thereby driving the threaded block 22 to move forward and backward, and the threaded block 22 drives the telescopic rod 17 to move forward and backward.

[0044] Further, by Figure 1-Figure 4 As shown, in order to reduce the pressure on the patient's thigh, a chamfer 23 is provided on the rear side of the contact pad 2, and a connecting groove 24 is provided on the left and right sides of the fixing bracket 1. A connecting block is fixedly connected to the position of each connecting groove 24 in the contact pad 2. The connecting block is a long strip structure and can be snap-connected with the connecting groove 24. The connecting block and the connecting groove 24 cooperate with each other to form a detachable structure of the contact pad 2.

[0045] When in use, the chamfer 23 can enable the device to gradually support the patient's thighs and knees, reducing the patient's thigh discomfort. Through the clamping connection between the connecting block and the connecting groove 24, the contact pad 2 can be easily removed from the upper side of the fixed bracket 1, making it convenient to replace the contact pad 2.

[0046] Further, by Figure 1-Figure 4 As shown, in order to adjust the support angle of the knee, a first airbag 25 is provided inside the first support pad 6, and a first inflation tube is connected to the lower side of the first airbag 25. A long groove 26 is provided in the middle of the contact pad 2 corresponding to the position of the first airbag 25, and an equipment cabin 27 is provided on the upper side of the fixed bracket 1. The first inflation tube passes through the bottom of the first support pad 6 and the long groove 26 and is connected to the equipment cabin 27. The lower side of the first support pad 6 is detachably connected to the contact pad 2 by Velcro;

[0047] It should be noted that a vent hole is provided on the side of the equipment cabin 27, and a plurality of air pumps are arranged inside the equipment cabin 27, and the first airbag 25 and each physiotherapy airbag 3 are corresponding, and the plurality of air pumps are connected to a control power supply, which can inflate and deflate the different physiotherapy airbags 3 in sequence, and by inflating and deflation of the first airbag 25, the support height of the patient's knee can be adjusted;

[0048] When in use, the support height of the patient's knee can be adjusted by inflating and deflating the first airbag 25. When the position of the first support pad 6 needs to be adjusted, the first support pad 6 can be removed from the upper side of the contact pad 2 through the Velcro between the first support pad 6 and the contact pad 2 to adjust the position. At this time, under the action of the long groove 26, the first inflation tube can slide back and forth inside the long groove 26, and will not affect the inflation and deflation effect of the first airbag 25.

[0049] Further, by Figure 1-Figure 4 As shown, in order to perform lower limb air pressure therapy on the patient, a connecting tube 28 is fixedly connected to the left and right sides of each physiotherapy airbag 3, and a physiotherapy bag 29 is connected to each connecting tube 28 away from the physiotherapy airbag 3, and every two adjacent physiotherapy bags 29 are fixedly connected;

[0050] The physiotherapy bag 29 is a hollow structure, the interior of which can be inflated and bulged. Two adjacent physiotherapy bags 29 are sewn together, and each physiotherapy bag 29 is provided with a Velcro on one side away from the connecting tube 28, so that the corresponding physiotherapy bags 29 on the left and right sides of the contact pad 2 can fit together to wrap the patient's legs. At this time, when the physiotherapy airbag 3 is inflated and deflated from the distal end of the patient's lower limb to the proximal end of the patient's lower limb, the corresponding physiotherapy bag 29 can also be inflated and deflated in turn, so that the patient's lower limbs can be pneumatically treated;

[0051] It should be noted that the controller for sequentially inflating and deflation of the multiple physiotherapy airbags 3 is a prior art. For example, the lower limb pneumatic therapy device or the anti-thrombotic pressure pump is a device that repeatedly inflates and deflates the multiple chamber airbags in sequence, thereby forming a cyclically changing pressure on the limbs and tissues, and uniformly and orderly compressing the distal end to the proximal end of the limbs, thereby promoting the flow of blood and lymphatic tissues and improving microcirculation, and accelerating the reflux of limb tissue fluid. In this embodiment, the controller used for sequentially inflating and deflation of the multiple physiotherapy airbags 3 is the same as that thereof, and no further description is given here.

[0052] In order to avoid supporting the left and right ankle bones of the patient's ankle joint, two lateral support pads 30 are fixedly connected to the upper side of the second support pad 8, and an auxiliary notch 31 is opened on the front side of the upper part of each lateral support pad 30, and a protruding block 32 is fixedly connected to the front side of the second support pad 8;

[0053] When the patient's foot steps on the support board, the patient's ankle and the proximal end of the ankle are supported by the lateral support pad 30 to keep the patient's foot stable. At this time, the auxiliary notch 31 can avoid the left and right ankle bones of the patient's ankle joint, thereby reducing the risk of pressure sores on the patient's ankle joint; the extension block 32 can support the patient's posterior ankle, thereby reducing the force on the patient's heel and reducing the risk of pressure sores on the patient's heel;

[0054] It should be further explained that the contact pad 2, the first support pad 6, the inclined pad 7, the second support pad 8 and the foot support pad 11 are all made of memory foam, and the outer side of the memory foam is covered with skin-friendly fabrics, such as plant fiber, pure cotton, etc., which can reduce the patient's discomfort;

[0055] When the present invention is used, the fixed bracket 1 can be firstly placed directly on the patient's bed, and then the patient's legs can be placed on the upper side of the contact pad 2, so that the first support pad 6 corresponds to the patient's popliteal fossa (back of the knee) position, and the patient's knee position is raised and supported. At this time, the patient's calf is located between the first support pad 6 and the second support pad 8, and the second support pad 8 is used to support the distal end of the patient's gastrocnemius muscle, which can be more suitable for ergonomics, increase the contact area between the patient's legs and the contact pad 2, the first support pad 6 and the second support pad 8, and thus can reduce the probability of pressure sores on the patient's legs. At this time, the support frame 5 can support the patient's feet, and thus can prevent or correct the patient's foot drop symptoms, and can also adjust the length of the telescopic rod 17 extending out of the fixed bracket 1, thereby adjusting the support angle of the patient's feet;

[0056] When air pressure therapy is required for the patient's legs, multiple therapy airbags 3 can be inflated and deflated in sequence from the distal end to the proximal end, and external pressurization is performed by connecting the therapy airbags 3 and the therapy bag 29 to an air pump to promote the return of venous blood and lymph fluid in the patient's lower limbs, thereby preventing deep vein thrombosis in the lower limbs and reducing swelling of the lower limbs;

[0057] When ankle pump exercise is needed, the patient's foot can be simply fixed by the Y-shaped elastic band 13, so that the patient can perform ankle pump exercise as the angle of the support frame 5 changes. When the patient's foot is fixed for a long time, the contact position between the fixing band 12 and the patient's foot can be changed by adjusting the direction of the elastic band 13 or moving the fixing band 12 upward or downward, thereby reducing the risk of pressure sores on the dorsum of the patient's foot.

[0058] The present invention has a novel structure, ingenious conception, and is simple and convenient to operate. Through this design, the probability of patients developing foot drop is effectively reduced, and the function of preventing or correcting the patient's foot drop symptoms is increased, thereby achieving the purpose of assisting patients in performing ankle pump exercises. The patient's feet can be well fixed, and the probability of pressure sores on the patient's feet is reduced. The patient's feet can be subjected to ankle pump exercise therapy at a larger angle, which is convenient for medical staff to operate and facilitates the adjustment of the knee support angle.

[0059] Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
