Technical Field

[0001] This utility model relates to the field of rehabilitation equipment technology, specifically a device for preventing thrombosis by combining gastrocnemius muscle contraction with passive ankle pump exercise. Background Technology

[0002] The gastrocnemius is one of the posterior muscles of the lower leg. It is located subcutaneously on the back of the lower leg and is a superficial muscle of the posterior calf group. It lies deep to the subcutaneous tissue, where the soleus muscle lies. The gastrocnemius muscle originates from the posterior aspect of the medial and lateral epicondyles of the femur with its medial and lateral heads. It descends and joins the three heads of the soleus muscle to form a bulging calf muscle in the upper part of the lower leg. It continues downward as the Achilles tendon and inserts into the calcaneal tuberosity. The two bellies of the gastrocnemius muscle are enlarged and close to each other at the lower angle of the popliteal fossa, forming an angle of 25°-30°.

[0003] However, existing thrombosis prevention devices that combine gastrocnemius muscle contraction with passive ankle pump exercise have imperfect fixation methods in actual use. If the patient moves involuntarily, the foot cover is easy to fall off with the movement, and the air inflator is easily pulled off, resulting in ineffective use. To address this problem, a thrombosis prevention device that combines gastrocnemius muscle contraction with passive ankle pump exercise is provided. Summary of the Invention

[0004] The purpose of this invention is to provide a device for preventing thrombosis by combining gastrocnemius muscle contraction with passive ankle pump exercise, thereby solving the problems mentioned in the background art. To achieve the above objective, this invention provides the following technical solution: a device for preventing thrombosis by combining gastrocnemius muscle contraction with passive ankle pump exercise, comprising an airbag, wherein a first fixing component and a second fixing component are provided on both sides of the outer wall of the airbag for fixing the lower leg and the foot respectively, a toe correction rod is provided on one side of the top of the airbag, an inflation hole is provided at one end of the airbag, a connector is detachably inserted into the inner cavity of the inflation hole, the connector is connected to an air pump through a delivery hose, and a connecting component is provided at one end of the airbag for fixing the connector.

[0005] Preferably, the first fixing component includes a first elastic band, a first round hook and loop fastener, and a first barbed hook and loop fastener. The two first elastic bands are respectively located on both sides of the outer wall of the airbag.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] The device can be fixed to the user's calf by the first fixing component and to the user's foot by the second fixing component. When the airbag is not inflated, it can bend to fit the back of the calf and the foot. After inflation, the internal pressure of the airbag increases, which straightens the bent position of the airbag, raises the instep to a certain angle, and causes the gastrocnemius muscle on the back of the calf to contract, thereby achieving the purpose of contracting and exercising the gastrocnemius muscle. This solves the problem that the fixing method of the existing gastrocnemius muscle contraction combined with passive ankle pump exercise antithrombosis device is not perfect in actual use. If the patient moves involuntarily, the foot sleeve is easy to fall off with the movement. The toe correction bar can further fix the foot and improve the fixation effect, and can also correct the toes.

[0013] By using the connecting components, the connector can be clamped together with the inflation port to fix the connector and prevent it from coming off the inflation port, which would affect the inflation process of the airbag. This solves the problem that the inflation connector of the existing gastrocnemius muscle contraction combined with passive ankle pump exercise antithrombosis device is easily pulled off during actual use, resulting in ineffective use.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figures 1 to 5This utility model provides a technical solution: a thrombosis prevention device combining gastrocnemius muscle contraction and passive ankle pump exercise, including an airbag 1. A first fixing component and a second fixing component are provided on both sides of the outer wall of the airbag 1 for fixing the lower leg and foot respectively. A toe correction rod 8 is provided on one side of the top of the airbag 1. An inflation port 9 is provided at one end of the airbag 1. A connector 10 is detachably inserted into the inner cavity of the inflation port 9. The connector 10 is connected to an air pump 11 via a delivery hose. A connecting component is provided at one end of the airbag 1 for fixing the connector 10. The device can be fixed to the user's lower leg by the first fixing component and to the user's foot by the second fixing component. When the airbag 1 is not inflated, it can bend to fit the back of the lower leg and the foot. After inflation, the internal pressure of the airbag 1 increases, causing the airbag 1 to bend. The bending position is straightened, causing the instep to rise to a certain angle, which contracts the gastrocnemius muscle on the back of the calf, achieving the purpose of contracting and exercising the gastrocnemius muscle. This solves the problem that the fixation method of the existing gastrocnemius muscle contraction combined with passive ankle pump exercise antithrombosis device is not perfect in actual use. If the patient moves involuntarily, the foot cover is easy to fall off with the movement. The setting of the toe correction rod 8 can further fix the foot and improve the fixation effect. It can also correct the toes. The setting of the connecting component can cooperate with the air hole 9 to clamp the connector 10, thereby fixing the connector 10 and preventing the connector 10 from falling off the air hole 9, which would affect the inflation process of the air bag 1. This solves the problem that the air connector of the existing gastrocnemius muscle contraction combined with passive ankle pump exercise antithrombosis device is easily pulled off during actual use, resulting in ineffective use.

[0022] In this embodiment, the first fixing component includes a first elastic band 2, a first round hook and loop fastener 3, and a first barbed hook and loop fastener 4. The two first elastic bands 2 are respectively located on both sides of the outer wall of the airbag 1. The first round hook and loop fastener 3 is disposed on one of the first elastic bands 2, and the first barbed hook and loop fastener 4 is disposed on the other first elastic band 2. The two first elastic bands 2 are wrapped around the calf, so that the first round hook and loop fastener 3 and the first barbed hook and loop fastener 4 are attached together, thereby fixing the airbag 1 to the calf.

[0023] In this embodiment, the second fixing component includes a second elastic band 5, a second round loop Velcro 6, and a second barbed Velcro 7. The two second elastic bands 5 are respectively disposed on both sides of the outer wall of the airbag 1. The second round loop Velcro 6 is disposed on one of the second elastic bands 5, and the second barbed Velcro 7 is disposed on the other second elastic band 5. The two second elastic bands 5 are wrapped around the sole of the foot, so that the second round loop Velcro 6 and the second barbed Velcro 7 are attached to each other, thereby fixing the airbag 1 to the sole of the foot.

[0024] In this embodiment, the connecting assembly includes a telescopic component, a lifting plate 12, a fixed cylinder 13, a lead screw 14, and a knob 15. The telescopic component is located at one end of the airbag 1, and the lifting plate 12 is located at the end of the telescopic component away from the airbag 1. A groove is provided on the side of the lifting plate 12 near the inflation port 9. The fixed cylinder 13 is fixedly inserted into the lifting plate 12. One end of the lead screw 14 is rotatably connected to one end of the airbag 1 via a bearing. The lead screw 14 is screwed into the inner cavity of the fixed cylinder 13. The knob 15 is located at the top of the lead screw 14. After the connector 10 is inserted into the inflation port 9, the knob 15 is rotated to drive the lead screw. 14. Rotation: Since the lead screw 14 is screwed into the inner cavity of the fixed cylinder 13, when the lead screw 14 rotates, the lifting plate 12 can slide downward in a straight line under the limiting action of the telescopic rod 17 and the telescopic cylinder 16. This allows the lifting plate 12 to cooperate with the inflation hole 9 to clamp and fix the connector 10, thereby fixing the connector 10 and preventing the connector 10 from detaching from the inflation hole 9, which would affect the inflation process of the airbag 1. This solves the problem that the inflation connector of the existing gastrocnemius muscle contraction combined with passive ankle pump exercise antithrombosis device is easily pulled off during actual use, resulting in ineffective use.

[0025] In this embodiment, the width of the groove is greater than the diameter of the delivery hose and less than the diameter of the connector 10.

[0026] In this embodiment, the telescopic assembly includes a telescopic cylinder 16, a telescopic rod 17, and a limiting component. The telescopic cylinder 16 is disposed at one end of the airbag 1. The telescopic rod 17 is slidably inserted into the inner cavity of the telescopic cylinder 16 and fixedly connected to one side of the outer wall of the lifting plate 12. The limiting component is disposed in the inner cavity of the telescopic cylinder 16 and fixedly connected to the outer wall of the telescopic rod 17. When the lifting plate 12 slides up and down, the telescopic rod 17 can be synchronously extended and retracted in the inner cavity of the telescopic cylinder 16. Under the combined action of the telescopic rod 17 and the telescopic cylinder 16, the fixed cylinder 13 and the lifting plate 12 can be prevented from rotating with the lead screw 14 when the lead screw 14 rotates, thereby improving the stability of the connecting assembly during use.

[0027] In this embodiment, the limiting component includes a limiting groove 18 and a limiting block 19. The limiting groove 18 is formed on one side of the inner wall of the telescopic cylinder 16. The limiting block 19 is slidably embedded in the inner cavity of the limiting groove 18 and fixedly connected to the outer wall of the telescopic rod 17. Under the combined action of the limiting groove 18 and the limiting block 19, one end of the telescopic rod 17 can always be inserted into the inner cavity of the telescopic cylinder 16, which improves the stability of the telescopic component during use. The inner cavity of the limiting groove 18 and the outer wall of the limiting block 19 are adapted to each other and are both dovetail-shaped, which can keep one end of the limiting block 19 embedded in the inner cavity of the limiting groove 18, which improves the stability of the limiting component during use and prevents the limiting block 19 from dislodging from the inner cavity of the limiting groove 18, which would cause the telescopic rod 17 to dislodge from the inner cavity of the telescopic cylinder 16.
