Description

Technical Field

[0001] The invention belongs to the technical field of medical devices, and in particular relates to an intermittent Achilles tendon traction combined with calf massager. Background Art

[0002] The main nerves of the lower limbs are the sciatic nerve, tibial nerve, and common peroneal nerve. Sciatic nerve injury is common in posterior hip dislocation, which manifests as paralysis of the knee flexor muscles, calf and foot muscles, and loss of sensation in the posterior thigh, lateral calf, and foot. Tibial nerve injury occurs in supracondylar femoral fractures and knee dislocations, resulting in paralysis of the gastrocnemius, soleus, toe flexors, and plantar muscles, and loss of sensation in the foot. Common peroneal nerve injury occurs in fractures of the peroneal head or peroneal neck, resulting in paralysis of the calf extensors, peroneus longus and brevis, and foot drop. Nerve injuries in the lower limbs should be surgically explored as soon as possible.

[0003] Because the muscles lose their ability to actively contract, some patients will develop deep vein thrombosis in the lower limbs, which affects their recovery progress and may even cause the blood clots to grow and fall off. In severe cases, pulmonary embolism may occur, which is life-threatening.

[0004] There are two methods for preventing deep vein thrombosis of the lower extremities: drug prevention and mechanical prevention. Drug prevention has been proven to be effective in preventing the occurrence of thrombosis, but it also brings the risk of bleeding. In severe cases, retroperitoneal hematoma, cerebral hemorrhage, and even life-threatening conditions may occur. Moreover, even with standardized preventive anticoagulation treatment, deep vein thrombosis of the lower extremities is still likely to occur, and the economic burden on patients is increased. Mechanical prevention avoids the risk of bleeding, is safer and more comfortable, and has been well promoted.

[0005] At present, physical therapy methods such as intermittent pneumatic pressurization pump, plantar arteriovenous pump therapy device, ankle pump exercise, etc. are commonly used in clinical practice. At the same time, auxiliary nursing measures such as raising the lower limbs, wearing anti-thrombotic elastic stockings, and lower limb muscle massage are adopted. Intermittent pneumatic pressurization pump is the most widely used mechanical prevention method in clinical practice at home and abroad. It uses a fully automatic sequential pressurized pneumatic pump to assist the blood return of the lower limbs, which is equivalent to a gentle squeeze from the bottom to the top starting from the feet to promote the blood and lymph return of the distal end. However, this method belongs to passive exercise, which only squeezes the patient's muscles. The patient's lower limb muscles are not active, and it cannot prevent muscle atrophy and joint ligament contracture in bedridden patients. This method is not suitable for situations such as wounds on the lower limbs and fresh surgical incisions, and has certain limitations. The arteriovenous foot pump is a clinical physical therapy device made by imitating the physiological effects of the plantar venous plexus. Its main function is to increase the amount of blood returning to the heart and promote the effective circulation of blood by simulating the squeezing of the plantar venous plexus during walking, and improve the arteriovenous hemodynamics and arterial vascular function of the patient's lower limbs. Its disadvantages are the same as those of the intermittent pneumatic pressure pump. The patient's lower limb muscles are not active, and it cannot prevent muscle atrophy and joint ligament contracture in bedridden patients.

[0039] 2. The leg massage component's circular massage stimulates the patient's calf muscles, promotes blood circulation in the paralyzed muscles, thereby preventing lower limb thrombosis and reducing the frequency of heel spasms.

[0040] 3. The lifting component continuously flips the patient's calf to stimulate the triceps surae and tibialis anterior muscles. The leg muscles, especially the triceps surae, have venous sinuses. The blood in these veins can only flow back to the heart with the help of muscle pumps. The contraction of the triceps surae and tibialis anterior muscles can squeeze the capillaries and lymphatic vessels therein, promoting the reflux and emptying of blood and lymph. The muscles relax, and blood and lymph flow back in. This exercise makes the muscles work like a pump, effectively promoting blood circulation in the entire lower limbs, changing the stagnant state of blood in the lower limb veins during long-term bed rest, so as to prevent deep vein thrombosis in the lower limbs.

[0041] 4. The limiting component presses the patient's ankle like a human hand, reducing the pressure on the patient's ankle and effectively preventing the occurrence of pressure sores.

[0042] 5. When in use, place the patient's foot into the foot adapter. There is no need to set a strap on the dorsum of the foot to forcibly fix the foot. Since the dorsum of the foot is full of soft tissues, blood vessels, and nerves, pressing with a strap for a few minutes will cause necrosis. The foot adapter can effectively fix the foot and prevent necrosis of the patient's foot.

[0043] 6. The driver simply provides power for the foot massage component, leg massage component, and lifting component to ensure the stability of the movement of the foot massage component, leg massage component, and lifting component. The application controller adjusts the movement frequency of the first control unit, the second control unit, and the third control unit. On this basis, the movement frequency and movement distance of the foot massage component are controlled by the first control unit; the movement frequency and movement distance of the leg massage component are controlled by the second control unit; and the movement frequency and lifting distance of the lifting component are controlled by the third control unit.

[0047] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0048] like Figure 1-15 An intermittent Achilles tendon stretching and calf massager is shown; it comprises: A support assembly 1 is provided with a massage position capable of placing the patient's calves and feet; The foot massage assembly 2 includes a first pusher 21, a foot adapter 22 and a position regulator 23; one end of the first pusher 21 extends out of the support assembly 1 and is connected to the foot adapter 22; one end of the position regulator 23 is fixedly connected to the first pusher 21, and the other end is fixedly connected to the support assembly 1; The leg massage assembly 3 includes a second pusher 31 and a leg massager 32; one end of the leg massager 32 is connected to the second pusher 31, and the other end is slidably connected to the support assembly 1; The lifting assembly 4 includes a lifting bag 41 and a lifter 42; one end of the lifter 42 is hinged to the support assembly 1; the lifting bag 41 is located between the lifter 42 and the support assembly 1; A limit assembly 5, one end of which is hinged to the support assembly 1, and the other end of which is detachably connected to the support assembly 1; The driving assembly is located inside the supporting assembly 1 ; the driving assembly is connected to the first pusher 21 , the second pusher 31 , and the lifting bag 41 respectively.

[0049] Furthermore, a controller is provided on the side wall of the support assembly 1. The controller is connected to the drive assembly via a wire, and the controller can control the opening and closing of the drive assembly.

[0050] The driving component drives the first pusher 21 to move, so that the foot massage component 2 drives the patient's foot to move, thereby achieving the effect of heel traction, exercising the Achilles tendon and foot muscles, promoting the recovery of foot muscle function, and also promoting blood circulation and lymphatic return in the lower limbs.

[0051] The driving component drives the second pusher 31 to move, so that the leg massage component 3 circulates and massages to stimulate the patient's calf muscles, promotes blood circulation in the paralyzed muscles, thereby preventing thrombosis in the lower limbs, and also reduces the frequency of heel spasms.

[0052] The driving component drives the third pusher to move, so that the lifting component 4 continuously flips the patient's calf, stimulating the triceps surae and tibialis anterior muscles; the leg muscles, especially the triceps surae, have venous sinuses. The blood in these veins can only flow back to the heart by relying on the action of muscle pumps; the contraction of the triceps surae and tibialis anterior muscles can squeeze the capillaries and lymphatic vessels therein, promoting the reflux and emptying of blood and lymph; the muscles relax, and the blood and lymph flow back in. This movement makes the muscles work like a pump, effectively promoting blood circulation in the entire lower limbs, changing the stagnant state of blood in the lower limb veins during long-term bed rest, so as to achieve the purpose of preventing deep vein thrombosis in the lower limbs.

[0053] The limiting component 5 presses the patient's ankle like a human hand, reducing the pressure on the patient's ankle and effectively preventing the occurrence of pressure sores.

[0054] In a specific example of the present application, the limiting assembly includes a fixed bracket, a limiter and a limiting structure. One end of the fixed bracket is slidably connected to the support assembly, and the other end is detachably connected to the support assembly. The fixed bracket is threadedly connected to the limiter. One end of the limiter passes through the fixed bracket to facilitate the rotational connection of the limiting structure. When in use, first reverse the fixed bracket, and then put the patient's leg into the interior of the support assembly; then completely install the fixed bracket on the support assembly so that both ends of the fixed bracket are connected to the support assembly, and then rotate the limiter to press the limiting structure on the patient's ankle to fix the patient's leg inside the support assembly.

[0055] Specifically, the fixed bracket includes a first bracket, a second bracket and a third bracket. One end of the second bracket is rotatably connected to the first bracket, and the other end is rotatably connected to the third bracket. One end of the first bracket away from the second bracket is rotatably connected to the support assembly. One end of the third bracket away from the second bracket is detachably connected to the support assembly. When the third bracket is installed on the support assembly, the first bracket is perpendicular to the second bracket, and the second bracket is perpendicular to the third bracket. The limiter is threadedly connected to the second bracket. When in use, the connection between the third bracket and the support assembly is first released and the first bracket, the second bracket, and the third bracket are rotated to expose the massage position on the support assembly, and then the patient's leg is placed inside the support assembly. Then the limiter is reversed and the third bracket is installed on the support assembly. Finally, the limiter is rotated to press the limit structure on the patient's ankle, which has the effect of fixing the patient's leg. At the same time, the contact surface between the limit structure and the patient's ankle is large, which reduces the pressure of the limit assembly on the patient's ankle and prevents soft tissue damage to the patient's ankle.

[0056] The limiter comprises a handle and a screw rod arranged along an axis. An end of the screw rod away from the handle passes through the second bracket and is rotatably connected with the limit structure.

[0057] Furthermore, the exterior of the limiting structure is wrapped with a soft cushion to reduce the patient's discomfort.

[0058] Preferably, the limiting component contacts the patient's ankle and presses against the patient's heel to prevent the patient's foot from being dislocated.

[0059] In some examples of the present application, a plurality of limiting arms are fixedly connected around the limiting structure, and the plurality of limiting arms are arranged circumferentially with the limiting device as the center. When the limiting structure is against the patient's ankle, the limiting arms contact the patient's foot side, further preventing the patient's foot from deflecting.

[0060] A groove is provided at one end of the foot adapter 22 away from the first pusher 21. When in use, the patient's foot is placed in the groove of the foot adapter 22, and there is no need to set a strap on the dorsum of the foot to forcibly fix the foot; since the dorsum of the foot is full of soft tissues, blood vessels, and nerves, pressing with a strap for a few minutes will cause necrosis, and the foot adapter 22 can prevent necrosis of the patient's foot while effectively fixing the foot.

[0061] Achilles tendon contracture patients not only have foot drop, but also have inversion. When the patient's foot is placed in the groove, the inverted foot will rest against the inner wall of the groove, achieving the purpose of correcting the inversion of the foot.

[0062] The position regulator 23 includes an adjusting knob 231, an adjusting rod 232 and a slider 233; the slider 233 is threadedly connected to the adjusting rod 232; the adjusting rod 232 is fixedly connected to the adjusting knob 231 after extending out of the support assembly 1. By turning the adjusting knob 231, the slider 233 can be driven to move, so as to change the position of the foot adapter 22, so as to match patients of different body shapes.

[0063] Preferably, the position regulator 23 further includes a limiting structure 234; the slider 233 slides along the limiting structure 234 driven by the adjusting rod 232. The purpose of the limiting structure 234 is to prevent the slider 233 from rotating around the adjusting rod 232. Specifically, the slider 233 is fixedly connected to the first pusher 21 .

[0066] Furthermore, the first control unit 12 includes a first control motor, a first push rod 126 and a first control chamber; the first control motor drives the first push rod 126 to slide inside the first control chamber; the side wall of the first control chamber is provided with a first working port 121, a first input port 125, a first regulating port 122, a first output port 124 and a first reflux port 123 in sequence; the first push rod 126 is provided with a first piston 127, a second piston 128 and a third piston 129 in sequence.

The driver 13 pumps the liquid in the storage bin 16 into the front part of the first driving bin through the first input pipe 134 and the first working pipe 212, driving the first driving rod to drive the foot adapter 22 to recover.

[0070] If the first control motor drives the first push rod 126 to move out of the first control chamber, the first piston 127 will block the first working port 121; the first input port 125 will be connected to the first regulating port 122; the first output port 124 will be connected to the first return port 123. At this time, the first input pipe 134 will be connected to the first regulating pipe 211; the first return pipe will be connected to the first return pipe 213.

[0071] Combination Figure 1-15 It can be seen that the first push rod 126 performs linear reciprocating motion under the drive of the first control motor, so as to achieve the purpose of controlling the driver 13 to be alternately connected with the front and rear of the first drive bin, drive the foot adapter 22 to perform reciprocating linear motion, drive the patient's foot to move, and achieve the effect of heel traction.

The driver 13 pumps the liquid inside the storage bin 16 into the front part of the second driving bin through the second input pipe 135 and the second working pipe 312, driving the second driving rod to drive the leg massager 32 to move toward the direction of the second driving bin.

[0076] If the second control motor drives the second push rod to move out of the second control chamber, the second piston 128 will block the second working port; the second input port will be connected to the second regulating port; the second output port will be connected to the second reflux port. At this time, the second input pipe 135 will be connected to the second regulating pipe 311; the second reflux pipe will be connected to the second reflux pipe 313. The driver 13 will pump the liquid in the storage chamber 16 into the rear part of the second driving chamber through the second input pipe 135 and the second regulating pipe 311, driving the second driving rod to drive the leg massager 32 to move in the direction away from the second driving chamber.

[0077] Combination Figure 1-15 It can be seen that the second push rod performs linear reciprocating motion under the drive of the second control motor, so as to achieve the purpose of controlling the driver 13 to be alternately connected with the front and rear of the second drive bin, driving the leg massager 32 to perform reciprocating linear motion, so that the leg massage component 3 performs a circular massage to stimulate the patient's calf muscles, promote blood circulation in the paralyzed muscles, and thus prevent thrombosis in the lower limbs, while also reducing the frequency of heel spasms.

[0078] In the schematic embodiment of the present application, the leg massager 32 includes a sliding structure and a massage unit; the sliding structure is connected to the second driving rod; one end of the massage unit is inserted into the support assembly 1 and fixedly connected to the sliding structure; the sliding structure is slidably connected to the support assembly 1.

[0079] At least two massage units are arranged on the sliding structure, and the plurality of massage units are arranged in a regular array on the sliding structure. The sliding structure is driven by the second push rod to make a reciprocating linear motion, and the massage units continuously slide on the patient's body surface to stimulate the patient's calf muscles and promote blood circulation.

[0080] Preferably, a buffer pad is provided at one end of the massage unit away from the sliding structure to prevent the massage unit from damaging the patient's skin.

[0081] In a specific example of the present application, a slideway is provided inside the support assembly 1; the sliding structure slides along the slideway to prevent the sliding structure from being displaced.

[0082] In the exemplary embodiment of the present application, Figure 1-15As shown, the third control unit 15 includes a third control motor, a third push rod and a third control compartment; the third control motor drives the third push rod to slide inside the third control compartment; the side wall of the third control compartment is provided with a third input port, a third working port and a third output port in sequence; the third push rod is provided with a seventh piston. The third input port is connected to the third input pipe 136; the third output port is connected to the third return pipe 163; the lifting bag 41 is connected to the third working port through the third working pipe 411.

[0083] Driven by the third control motor, the seventh piston can selectively block the third input port and the third output port. When the seventh piston blocks the third input port, the lifting bag 41 is connected to the storage bin 16. Under the pressure of the patient's calf, the liquid inside the lifting bag 41 will enter the storage bin 16, causing the lifting bag 41 to shrink. At this time, the lifting assembly 4 drives the support assembly 1 to descend. When the seventh piston blocks the third output port, the lifting bag 41 is connected to the driver 13. The driver 13 injects the liquid in the storage bin 16 into the lifting bag 41, increasing the volume of the lifting bag 41, thereby increasing the angle between the support assembly 1 and the lifter 42, causing the support assembly 1 to rise.

[0084] The second push rod performs linear reciprocating motion driven by the second control motor, so that the lifting bag 41 is alternately connected with the storage bin 16 and the driver 13, so that the lifting bag 41 is continuously filled and then contracted, driving the support assembly 1 to continuously rise and then fall, repeatedly stimulating the leg muscles such as the triceps surae and the tibialis anterior. The contraction of the triceps surae and the tibialis anterior can squeeze the capillaries and lymphatic vessels therein, promote the reflux and emptying of blood and lymph; the muscles relax, and the blood and lymph flow back in. This movement makes the muscles work like a pump, effectively promoting the blood circulation of the entire lower limbs, changing the stagnant state of the lower limb venous blood during long-term bed rest, so as to achieve the purpose of preventing deep vein thrombosis of the lower limbs.

[0085] Preferably, the lifter 42 includes a pad 421 ; one end of the pad 421 is hinged to the support assembly 1 ; and the lift bag 41 is located between the pad 421 and the support assembly 1 .

[0086] Furthermore, the lifter 42 further includes a limit plate 422, which is located on both sides of the pad 421, one end of the limit plate 422 is fixedly connected to the pad 421, and the other end is slidably connected to the support assembly 1. The purpose of the limit plate 422 is to prevent the pad 421 from deflecting and increase the structural stability.

[0087] In some embodiments of the present application, Figure 1-15As shown, the driver 13 is connected to the first input pipe 134, the second input pipe 135, and the third input pipe 136 respectively through the buffer chamber 131; the driver 13 pumps the liquid inside the storage chamber 16 into the inside of the buffer chamber 131, and then pushes the liquid into the first control unit 12, the first control unit 12, and the first control unit 12 through the buffer chamber 131 to drive the foot massage component 2, the leg massage component 3, and the lifting component 4 to move.

[0088] Preferably, a pressure regulator 132 is provided on the side wall of the buffer bin 131; one end of the pressure regulator 132 is connected to the buffer bin 131, and the other end is connected to the storage bin 16 through a pressure relief pipe 133. When the pressure inside the buffer bin 131 is too high, the pressure regulator 132 opens to introduce the liquid inside the buffer bin 131 into the interior of the storage bin 16 through the pressure relief pipe 133.

[0089] Specifically, the pressure regulator 132 includes a pressure regulating chamber, a pressure regulating piston, and a spring; the pressure regulating piston and the spring are both located inside the pressure regulating chamber; one end of the pressure regulating chamber is connected to the buffer chamber 131, and the other end is connected to the pressure relief line 133; the spring presses the pressure regulating piston toward the buffer chamber 131. When the pressure inside the buffer chamber 131 is greater than the pressure of the spring on the pressure regulating piston, the spring will be squeezed, causing the spring to contract and drive the pressure regulating piston to move away from the buffer chamber 131, so that the liquid inside the buffer chamber 131 can be discharged, reducing the pressure inside the buffer chamber 131.

[0090] The purpose of this design is that the driver 13 simply provides power for the foot massage component 2, the leg massage component 3, and the lifting component 4. The application controller adjusts the movement frequency of the first control unit 12, the second control unit 14, and the third control unit 15. After that, the movement frequency and movement distance of the foot massage component 2 are controlled by the first control unit 12; the movement frequency and movement distance of the leg massage component 3 are controlled by the second control unit 14; and the movement frequency and lifting distance of the lifting component 4 are controlled by the third control unit 15.
