Technical Field

[0001] The present invention relates to the technical field of medical equipment, in particular to an auxiliary device for promoting ankle pump movement of patients. Background Art

[0002] Deep vein thrombosis refers to the abnormal coagulation of blood in the deep vein cavity, which blocks the venous lumen, leads to venous reflux obstruction, and causes clinical symptoms such as distal venous hypertension, limb swelling, pain and superficial vein dilation. It is more common in the lower limbs of postoperative patients and can cause varying degrees of chronic deep vein insufficiency, which can cause disability in severe cases.

[0003] Therefore, in major hospitals, in order to prevent deep vein thrombosis in patients after surgery, they are often required to perform ankle pump exercises on their own to promote blood circulation and lymphatic return in the patients' lower limbs.

[0004] However, without the supervision of medical staff, patients tend to be lazy, making it difficult for them to continuously and independently perform ankle pump exercises. At present, no one has invented an auxiliary device that is extremely effective in promoting ankle pump exercises for patients to use.

[0021] The power switch is connected between the forward and reverse motors and the power box.

[0022] Preferably, it also includes a lifting device for lifting the patient's heels when the patient lies flat on the bed;

[0023] The lifting device includes a support plate and a detachable flexible support pad which is laid flat on the upper surface of the support plate; the middle part of the rear side surface of the support plate is fixed as a whole with the front wall of the lower end of the hollow fixed column; the middle part of the upper end surface of the flexible support pad is recessed downward to form a recessed portion for limiting the patient's heel when the flexible support pad lifts the patient's heel; the recessed portion is located directly below the turntable.

[0024] Preferably, the support plate is made of metal, and the bottom surface of the support plate is formed into a serrated structure to form an anti-slip surface.

[0025] Preferably, a layer of male Velcro is provided on the lower bottom surface of the flexible support pad, and a layer of female Velcro for adhering the male Velcro is provided on the upper end surface of the support plate.

[0026] The beneficial effects of the present invention are:

[0027] First, the auxiliary device provided by the present invention for promoting ankle pump exercise of patients is installed at the end of the bed during specific implementation. The patient lies flat on the bed so that his toes face upward and extend into the foot slot from bottom to top. After the corresponding work is completed, the rotating device is started. When the rotating disk is driven to rotate by the rotating device, the sole of the patient's foot fixed in the foot slot can rotate circumferentially, so that the patient's ankle can continuously make a circular motion. On the one hand, the corresponding circular motion can be summarized as plantar flexion, inversion, dorsiflexion and extension of the patient's ankle joint. The "circular movement" combined with the eversion action can quickly promote the blood circulation and lymphatic return of the patient's lower limbs, and is more effective in increasing the peak velocity of the patient's femoral vein blood flow than the patient performing ankle flexion and extension exercises alone. On the other hand, when the present invention is working, it can automatically drive the patient's ankle to perform ankle pump exercises, thereby eliminating the need to force the patient to perform ankle pump exercises independently, saving the patient effort and avoiding fatigue, and preventing the patient from being lazy, thereby eliminating the need for medical staff to continuously supervise the patient's ankle pump exercises. Therefore, the present invention has strong practicality and good use effect.

[0028] Secondly, in the technical scheme, on the one hand, the present invention is provided with the annular inflatable ring for covering the sole of the patient's foot, so that the sole of the patient's foot is covered by the annular inflatable ring in the unsaturated inflated state. When the patient's foot moves around the ring with the rotation of the turntable, the annular inflatable ring in the unsaturated inflated state can effectively play a certain buffering and anti-collision role to protect the patient's foot, so that the patient's foot is not easily injured by the rotation, so that the present invention has good reliability in use. On the other hand, when the height adjustment bolt is loosened, the height of the inverted L-shaped support frame is adjustable, so that the height position of the rotating device is adjustable, so that the foot slot can be adjusted to a suitable position to fit the soles of patients with different sole lengths, so that the present invention can be used by adults and children and has strong adaptability in use, and when it is adjusted, the patient's foot can be inserted into or removed from the foot slot, so that the present invention has better reliability in use, and thus the use effect of the present invention can be effectively improved.

[0029] Third, in this embodiment, on the one hand, because the rotating device includes the turntable, a forward and reverse motor for controlling the turntable to rotate horizontally clockwise or horizontally counterclockwise, and a power switch for controlling the operation of the forward and reverse motor, the power switch is provided with a first operating button for driving the forward and reverse motor to rotate forward to drive the turntable to rotate horizontally clockwise, and a second operating button for driving the forward and reverse motor to rotate reversely to drive the turntable to rotate horizontally counterclockwise. In this way, the present invention can drive the turntable to rotate horizontally clockwise and horizontally counterclockwise in a cyclic manner, and the turntable rotates alternately horizontally clockwise and horizontally. When it rotates counterclockwise, it can better accelerate the blood circulation and lymphatic return of the patient's lower limbs, increase the peak velocity of the patient's femoral vein blood flow more quickly, and make the patient's ankle pump exercise effect better. On the other hand, the supporting device includes a support plate and a detachable flexible support pad laid flat on the upper end surface of the support plate. The support plate is made of metal and has the anti-slip surface, so it can be placed firmly. The flexible support pad can comfortably support the patient's heel, and the recessed part on the flexible support pad can well limit the displacement of the patient's heel, so as to effectively increase the stability of the patient's ankle when doing ankle pump exercise. Therefore, the use effect of the present invention can achieve the best. BRIEF DESCRIPTION OF THE DRAWINGS

[0043] The technical solution of the present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments, so as to more clearly and intuitively understand the inventive essence of the present invention.

[0044] Combination Figure 1 , Figure 2 and Figure 3 As shown;

[0045] The auxiliary device 1000 provided by the present invention for promoting ankle pumping of a patient comprises a fixing frame 10 suitable for being placed at the end of a bed and a rotating device 20 for promoting the patient's ankle joint to automatically perform a circular motion when the patient lies flat;

[0046] The rotating device 20 is installed on the fixing frame 10, and has a horizontally arranged turntable 201. A foot slot 2011 for fitting the sole of the patient's foot is opened downwardly from a non-central position on the upper end surface of the turntable 201.

[0047] Based on the above, it is clear that: the auxiliary device 1000 provided by the present invention for promoting ankle pump movement of patients is mainly installed at the foot of the bed during specific implementation. The patient lies flat on the bed so that his toes face upward and extend into the foot slot 2011 from bottom to top. After the corresponding work is completed, the rotating device 20 is started. When the turntable 201 is driven to rotate by the rotating device 20, the sole of the patient's foot fixed in the foot slot 2011 can rotate circumferentially, so that the patient's ankle can continuously make a circular motion.

[0048] On the one hand, the corresponding circular movement can be summarized as a "circular movement" that combines the plantar flexion, inversion, dorsiflexion and eversion movements of the patient's ankle joint, which can quickly promote the blood circulation and lymphatic return of the patient's lower limbs, and increase the patient's femoral venous blood flow peak velocity better than the patient performing ankle flexion and extension exercises alone.

[0049] On the other hand, when the present invention is working, it can automatically drive the patient's ankle to perform ankle pump exercise, thereby eliminating the need to force the patient to perform ankle pump exercise independently, saving the patient effort and avoiding fatigue, and preventing the patient from being lazy and eliminating the need for medical staff to continuously supervise the patient's ankle pump exercise.

[0050] Furthermore, the present invention has strong practicability and good use effect.

[0051] Furthermore, in the technical solution, the present invention also includes an annular inflatable ring 30 for covering the sole of the patient's foot;

[0052] The foot groove 2011 is annular, the outer diameter of the annular inflatable ring 30 is matched with the inner diameter of the foot groove 2011, the outer wall of the annular inflatable ring 30 is adhered to the inner wall of the foot groove 2011, and the annular inflatable ring 30 is in a non-saturated inflation state.

[0053] Thus, the sole of the patient's foot is covered by the annular inflatable ring 30 in the unsaturated inflated state. When the sole of the patient's foot moves in a circle with the rotation of the turntable 201, the annular inflatable ring 30 in the unsaturated inflated state can effectively play a certain buffering and anti-collision role to protect the sole of the patient's foot, so that the sole of the patient's foot is not easily injured by the force, and the present invention has good reliability in use.

[0054] Moreover, in this embodiment, the fixing frame 10 is formed into an inverted L-shaped structure; the upper portion thereof faces the head of the bed; and the rotating device 20 is fixedly mounted on the front end of the fixing frame 10 of the inverted L-shaped structure.

[0055] Preferably, the fixing frame 10 comprises a hollow fixing column 101, an inverted L-shaped support frame 102 with an upper portion arranged toward the head of the bed, and a height adjustment bolt 103 for locking the inverted L-shaped support frame 102;

[0056] The top surface of the hollow fixing column 101 is provided with a notch 1011 penetrating downward to the inner cavity thereof; the rear lower end of the inverted L-shaped support frame 102 is inserted into the hollow fixing column 101 from the notch 1011; the height adjustment bolt 103 is screwed into the hollow fixing column 101 from the outer wall of the upper end thereof and abuts against the outer wall of the rear lower end of the inverted L-shaped support frame 102; the rotating device 20 is fixedly arranged at the upper front end of the inverted L-shaped support frame 102;

[0057] When the height adjustment bolt 103 is loosened, the height of the inverted L-shaped support frame 102 can be adjusted, so that the height position of the rotating device 20 can be adjusted.

[0058] Therefore, the foot covering groove 2011 can be adjusted to a suitable position to cover the soles of patients with different sole lengths, so that the present invention can be used by both adults and children and has strong adaptability. When the foot covering groove 2011 is adjusted, the soles of the patients can be inserted into or removed from the foot covering groove 2011, so that the present invention has better reliability.

[0059] Thereby, the use effect of the present invention can be effectively improved.

[0060] Furthermore, in the present technical solution, the rotating device 20 includes the rotating disk 201 and a forward and reverse motor 202 for controlling the rotating disk 201 to rotate horizontally clockwise or horizontally counterclockwise;

[0061] Among them, the front end of the inverted L-shaped support frame 102 is downwardly provided with an installation opening 1021; the forward and reverse motor 202 is downwardly fixed to the installation opening 1021 so that its lower end rotating shaft 2021 is located in the front and lower part of the inverted L-shaped support frame 102; a screw groove 2012 is downwardly provided at the center position of the upper end surface of the turntable 201; the lower end of the rotating shaft 2021 of the forward and reverse motor 202 is threadedly connected to the screw groove 2012 so as to be connected and fixed to the turntable 201, and when the turntable 201 is fixed, the distance between its upper end surface and the lower bottom surface of the forward and reverse motor 202 is at least 10 cm, so that there is enough space to accommodate the patient's toes.

[0062] Furthermore, in a specific implementation, the rotating device 20 further includes a power switch 203 for controlling the operation of the forward and reverse motor 202;

[0063] The power switch 203 is provided with a first operating button 2031 for driving the forward and reverse motor 202 to rotate forward to drive the turntable 201 to rotate horizontally clockwise, and a second operating button 2032 for driving the forward and reverse motor 202 to rotate horizontally counterclockwise.

[0064] In this way, the present invention can drive the rotating disk 201 to rotate horizontally clockwise and counterclockwise in a cyclic manner. When the rotating disk 201 rotates horizontally clockwise and counterclockwise alternately, it can better accelerate the blood circulation and lymphatic return of the patient's lower limbs, so that the peak velocity of the femoral vein blood flow of the patient can be increased more quickly, so that the patient's ankle pump exercise effect is better.

[0065] Preferably, in one embodiment, the rotating device 20 further includes a power supply box 204 for supplying power to the forward and reverse motor 202;

[0066] The power switch 203 is connected between the forward and reverse motor 202 and the power box 204 .

[0067] In this way, the present invention can save the need for an external power supply when in use, making the operation convenient.

[0068] It should be noted here that the corresponding power box 204 and the power switch 203 having the corresponding first operation button 2031 and the corresponding second operation button 2032 can be purchased and used directly on the market or online. They are existing mature products, and their details will not be elaborated here.

[0069] Meanwhile, in a specific implementation, the present invention further comprises a lifting device 40 for lifting the heels of the patient when the patient lies flat on the bed;

[0070] Among them, the lifting device 40 includes a support plate 401 and a detachable flexible support pad 402 which is flat on the upper end surface of the support plate 401; the middle part of the rear side surface of the support plate 401 is fixed as a whole with the front wall of the lower end of the hollow fixed column 101; the middle part of the upper end surface of the flexible support pad 402 is recessed downward to form a recessed portion 4021 for limiting the patient's heel when it lifts the patient's heel; the recessed portion 4021 is located directly below the turntable 201.

[0071] Furthermore, the support plate 401 is made of metal, and the bottom surface of the support plate 401 is formed into a sawtooth structure to form an anti-slip surface 4011 .

[0072] From this, it can be seen that: the support plate 401 is made of metal and has the anti-slip surface 4011, so that it can be placed stably, the flexible support pad 402 can comfortably support the patient's heel, and the recessed part 4021 on the flexible support pad 402 can effectively limit the displacement of the patient's heel, so as to effectively increase the stability of the patient's ankle when doing ankle pump exercises.

[0073] Furthermore, the use effect of the present invention can achieve the best.

[0074] It should be added that, in a specific implementation, a layer of male Velcro (not shown) is provided on the bottom surface of the flexible support pad 402, and a layer of female Velcro 4012 for adhering the male Velcro (not shown) is provided on the upper end surface of the support plate 401.
