Description

Technical Field

[0001] This invention relates to the field of medical device technology, and in particular to a wearable diabetic foot treatment device. Background Technology

[0002] Diabetic foot is a complication of diabetes and a major cause of disability and even death in diabetic patients. Traditional Chinese medicine often uses medicated baths to treat diabetic foot problems. These baths can promote blood circulation in the large and small blood vessels of the foot, which has a positive and beneficial effect on the recovery of the foot. However, existing foot bath basins are too simple in structure, only allowing for basic soaking in Chinese medicine, resulting in less than ideal therapeutic effects. Furthermore, the treatment time is relatively long, and it is very inconvenient for patients to move around during treatment.

[0003] Therefore, we propose a wearable diabetic foot treatment device that can improve treatment outcomes and is easy to move. Summary of the Invention

[0004] In order to overcome the shortcomings of existing foot bath basins, which are too simple in structure, have poor treatment effect, and are not convenient to move, this invention provides a wearable diabetic foot treatment device that can improve the treatment effect and is easy to move.

[0005] This invention is implemented through the following technical approach: A wearable diabetic foot treatment device includes a foot-shaped tube, a cover tube rotatably connected to the foot-shaped tube, and a piston tube fixedly connected to the cover tube on the side away from the foot-shaped tube. A piston rod is slidably connected inside the piston tube, a support frame is fixedly connected to the top of the piston rod, a first elastic element is connected between the piston rod and the piston tube, an air intake assembly communicates between the piston tube and the foot-shaped tube, a negative pressure unit is fixedly connected to the side of the foot-shaped tube near the air intake assembly, a pressure frame is slidably connected to the end of the air intake assembly near the foot-shaped tube, the pressure frame extends into the foot-shaped tube, a spray assembly is fixedly connected to the foot-shaped tube, a water inlet frame is fixedly connected to the side of the foot-shaped tube near the spray assembly, the water inlet frame communicates with the spray assembly, a fixing strap is fixedly connected to the top of the foot-shaped tube, and a foot plate is slidably connected inside the foot-shaped tube.

[0006] As an improvement to the above solution, the support frame is arc-shaped to fit the patient's leg.

[0007] As an improvement to the above solution, the air intake assembly consists of a hose and a hollow cylinder, with the hose connected to the piston cylinder and the hollow cylinder connected to the foot-shaped cylinder.

[0008] As an improvement to the above solution, the spray assembly consists of a small pump and a spray frame, with the spray frame extending into the foot-shaped cylinder.

[0009] As an improvement to the above solution, a circulation mechanism for controlling the circulation of the medicine liquid inside the foot-shaped cylinder is also included. The circulation mechanism is disposed in the foot-shaped cylinder and includes a first water pipe connected to the foot-shaped cylinder. The tail end of the first water pipe is connected to the water inlet frame. A first baffle is slidably connected inside the water inlet frame, and a second elastic element is symmetrically arranged between the first baffle and the water inlet frame.

[0010] As an improvement to the above solution, a sealing mechanism is also included for fitting the patient's leg and sealing the inside of the foot-shaped tube. The sealing mechanism is disposed on the foot-shaped tube and the cover tube. The sealing mechanism includes symmetrically arranged fixing rods, which are respectively fixedly connected to the foot-shaped tube and the cover tube on the side near the fixing strap. The fixing rods are slidably connected to a second baffle. A third elastic element is connected between the second baffle and the adjacent fixing rod. The second baffle is slidably connected to a symmetrically arranged third baffle. A fourth elastic element is connected between the third baffle and the adjacent second baffle.

[0011] As an improvement to the above solution, a draining mechanism is also included for draining the liquid medicine inside the foot-shaped cylinder. The draining mechanism is disposed in the foot-shaped cylinder and includes a drain pipe that is connected to the foot-shaped cylinder. A blocking block is slidably connected to the foot-shaped cylinder, and the blocking block blocks the drain pipe. An upper pull bracket is fixedly connected to the blocking block, and a guide rod is fixedly connected to the foot-shaped cylinder. The upper pull bracket is slidably connected to the guide rod, and a fifth elastic element is connected between the upper pull bracket and the guide rod.

[0012] As an improvement to the above solution, a reinforcement mechanism is also included for locking and reinforcing the connection between the foot-shaped cylinder and the cover cylinder. The reinforcement mechanism is disposed on the piston cylinder and includes a second water pipe connected to the bottom end of the piston cylinder. A square frame is fixedly connected to the cover cylinder. The tail end of the second water pipe is connected to the square frame of the cover cylinder. A push block is slidably connected inside the square frame of the cover cylinder, and symmetrically arranged locking blocks are slidably connected inside the square frame of the cover cylinder.

[0013] As an improvement to the above solution, the side of the push block near the locking block is tapered, and both the side of the locking block near the push block and the side extending out of the square frame of the cover cylinder are inclined, with the push block and the locking block engaging in a pressing fit.

[0014] As an improvement to the above solution, an adjustment mechanism for adjusting the height of the foot plate is also included. The adjustment mechanism is disposed in the foot-shaped cylinder and includes a pressing block. The pressing block is slidably connected to the foot-shaped cylinder and is pressed against the foot plate. The foot-shaped cylinder is threadedly connected to a threaded rod, and the left end of the threaded rod is rotatably connected to the pressing block.

[0015] This invention has the following advantages: 1. The patient inserts their foot into the foot-shaped tube and secures their leg with a fixing strap. When the patient sits down, the pressure frame slides upward and lifts. The spray assembly draws out the medicine and sprays it into the cap tube to soak the patient's foot. During the treatment, if the patient gets up and moves, the pressure frame slides downward to fit the instep of the patient, thus cooperating with the foot plate to fix the position of the patient's foot. With the fixing strap, the device can be fixed to the patient's leg and move with the patient. After the soaking treatment, the medicine in the foot-shaped tube is drained, and the inside of the foot-shaped tube is made into a negative pressure state by a negative pressure machine. Negative pressure treatment can help improve the healing speed of the diseased foot.

[0016] 2. When the medicine in the foot-shaped tube enters the first water pipe, the flowing medicine squeezes the first baffle to slide to the right and block the external pipe. The spray component continues to draw in the medicine, which allows the medicine in the foot-shaped tube to circulate and improve the treatment effect.

[0017] 3. After the patient's foot is inserted into the foot-shaped tube, the second and third baffles on the left and right sides can slide and extend under the action of the third and fourth elastic elements, thus fitting the patient's leg and sealing the upper side of the foot-shaped tube and the cover tube. During immersion therapy, this can prevent the medicine from overflowing. During negative pressure therapy, the sealed foot-shaped tube can also ensure the treatment effect.

[0018] 4. After the soaking treatment, the pull frame slides upward, causing the blocking block to move upward and no longer block the drain pipe. The medicine in the foot-shaped tube can then be discharged through the drain pipe, so that the negative pressure machine can perform negative pressure treatment on the patient's feet. This makes it easier to discharge the medicine after treatment without the patient having to put on or take off the device.

[0019] 5. The piston rod slides downward to squeeze the liquid through the second water pipe into the square frame at the lower front of the cap cylinder, which in turn causes the locking block to slide out of the square frame and lock the foot-shaped cylinder, thereby reinforcing the connection between the foot-shaped cylinder and the cap cylinder and preventing liquid leakage.

[0020] 6. The rotation of the threaded rod drives the compression block to move left and right, thereby squeezing the foot plate to slide up and down. In this way, the height of the foot plate can be adjusted as needed to adapt to the size of different patients' feet. Attached Figure Description

Detailed Implementation

[0033] The technical solution will be further described below with reference to specific embodiments. It should be noted that the terms "up," "down," "left," and "right" used in this document refer only to the position of the structure shown in the corresponding drawings. The serial numbers assigned to components in this document, such as "first," "second," etc., are only used to distinguish the described objects and have no sequential or technical meaning. Unless otherwise specified, terms such as "connection" and "linkage" in this application include both direct and indirect connections (linkages).

[0034] Example 1: A wearable diabetic foot treatment device, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the device includes a foot-shaped cylinder 1, a cover cylinder 2, a piston cylinder 3, a piston rod 4, a support frame 5, a first elastic element 6, an air intake assembly 7, a negative pressure unit 8, a pressure frame 9, a spray assembly 10, a water inlet frame 11, a fixing strap 12, and a foot plate 13. The cover cylinder 2 is rotatably connected to the left side of the foot-shaped cylinder 1. The piston cylinder 3 is fixedly connected to the left side of the cover cylinder 2. The piston rod 4 is slidably connected inside the piston cylinder 3. The support frame 5, which is arc-shaped, is fixedly connected to the upper end of the piston rod 4 to conform to the patient's leg. The first elastic element 6 connects the piston rod 4 and the piston cylinder 3. The air intake assembly 7, which is a flexible hose, connects the piston cylinder 3 and the foot-shaped cylinder 1. It consists of a hollow cylinder and a hose connected to the piston cylinder 3. The hollow cylinder is connected to the upper right side of the foot-shaped cylinder 1. A negative pressure machine 8 is fixedly connected to the upper right side of the foot-shaped cylinder 1. A pressure frame 9 is slidably connected inside the hollow cylinder at the lower part of the air intake assembly 7. The lower part of the pressure frame 9 extends into the foot-shaped cylinder 1. A spray assembly 10 is fixedly connected to the upper right side of the foot-shaped cylinder 1. The spray assembly 10 consists of a small pump and a spray frame. The spray frame extends into the foot-shaped cylinder 1. A water inlet frame 11 is fixedly connected to the upper right side of the foot-shaped cylinder 1. The water inlet frame 11 is connected to the small pump of the spray assembly 10. A fixing strap 12 is fixedly connected to the upper side of the foot-shaped cylinder 1. A foot plate 13 is slidably connected to the lower part of the foot-shaped cylinder 1.

[0035] When using the device, the operator controls the cover cylinder 2 to rotate and open on the foot-shaped cylinder 1. The patient then inserts their foot into the foot-shaped cylinder 1, and the patient's leg is secured by the fixing strap 12. The operator then controls the cover cylinder 2 to reverse and close. After the cover cylinder 2 is closed, the patient can sit down. When the patient sits down, their thighs press against the support frame 5, causing the piston rod 4 to slide downwards. The first elastic element 6 deforms, and the downward sliding of the piston rod 4 draws air through the air intake assembly 7, which in turn drives the pressure frame 9 to slide upwards and lift. The operator then connects an external pipe to the water inlet frame 11, and through the spray assembly 10, draws out the medicinal solution and sprays it into the cover cylinder 2 to soak the patient's feet for treatment. During the treatment, if the patient gets up and moves, the piston rod 4 slides upward and resets under the action of the first elastic element 6. The piston rod 4 slides upward and squeezes air into the air intake assembly 7, which in turn pushes the pressure frame 9 downward. The pressure frame 9 slides downward and fits against the instep of the patient, and then cooperates with the foot plate 13 to fix the position of the patient's foot. With the help of the fixing strap 12, the device can be fixed on the patient's leg and move with the patient. After the soaking treatment, the staff drains the medicine from the foot-shaped tube 1, and then uses the negative pressure machine 8 to put the inside of the foot-shaped tube 1 into a negative pressure state. Negative pressure treatment can help improve the healing speed of the diseased foot.

[0036] Example 2: Based on Example 1, such as Figure 1 , Figure 2 , Figure 5 and Figure 6As shown, it also includes a circulation mechanism, which can control the circulation of the medicine liquid in the foot-shaped cylinder 1. The circulation mechanism includes a first water pipe 14, a first baffle 15, and a second elastic element 16. The upper right side of the foot-shaped cylinder 1 is connected to the first water pipe 14, and the lower end of the first water pipe 14 is connected to the water inlet frame 11. The first baffle 15 is slidably connected inside the water inlet frame 11, and the first baffle 15 and the water inlet frame 11 are connected by a second elastic element 16 that is symmetrically arranged vertically.

[0037] By setting up a circulation mechanism, the circulation of the medicine in the foot-shaped cylinder 1 can be controlled to improve the treatment effect. The specific operation is as follows: When the amount of medicine in the foot-shaped cylinder 1 increases to the first water pipe 14, the medicine will enter the water inlet frame 11 along the first water pipe 14, which will then squeeze the first baffle 15 to slide to the right. The second elastic element 16 will deform, and after the first baffle 15 slides to the right, it will block the external pipe. At this time, the spray assembly 10 continues to draw the medicine, which will make the medicine in the foot-shaped cylinder 1 circulate and improve the treatment effect.

[0038] like Figure 1 , Figure 2 , Figure 7 and Figure 8 As shown, it also includes a sealing mechanism that can fit the patient's leg to seal the inside of the foot-shaped tube 1. The sealing mechanism includes a fixed rod 17, a second baffle 18, a third elastic element 19, a third baffle 20, and a fourth elastic element 21. The foot-shaped tube 1 and the cover tube 2 are both fixedly connected to the upper part of the fixed rod 17. The second baffle 18 is slidably connected to the fixed rod 17. The third elastic element 19 is connected between the second baffle 18 and the adjacent fixed rod 17. The second baffle 18 is slidably connected to the front and rear symmetrical third baffle 20. The third baffle 20 is connected between the adjacent second baffle 18 and the fourth elastic element 21.

[0039] By setting up a sealing mechanism, the space between the foot-shaped tube 1, the cover tube 2, and the patient's leg can be sealed to ensure the treatment effect. The specific operation is as follows: When the cover tube 2 is rotated open, the left-side fixing rod 17, the second baffle 18, the third elastic element 19, the third baffle 20, and the fourth elastic element 21 will all rotate with the cover tube 2. When the patient's foot is inserted into the foot-shaped tube 1, the cover tube 2 reverses, causing the left-side fixing rod 17, the second baffle 18, the third elastic element 19, the third baffle 20, and the fourth elastic element 21 to reverse and reset. Under the action of the third elastic element 19 and the fourth elastic element 21, the second baffle 18 and the third baffle 20 can slide and extend, thereby fitting the patient's leg to seal the upper side of the foot-shaped tube 1 and the cover tube 2. During immersion treatment, this can prevent the medicine from overflowing. During negative pressure treatment, the sealed foot-shaped tube 1 can also ensure the treatment effect.

[0040] like Figure 1 and Figure 9As shown, it also includes a drainage mechanism that can drain the liquid medicine in the foot-shaped cylinder 1. The drainage mechanism includes a drain pipe 22, a blocking block 23, an upper pull bracket 24, a guide rod 25, and a fifth elastic element 26. The lower front part of the foot-shaped cylinder 1 is connected to the drain pipe 22. The lower front part of the foot-shaped cylinder 1 is slidably connected to the blocking block 23, which blocks the rear end of the drain pipe 22. The upper pull bracket 24 is fixedly connected to the blocking block 23. The guide rod 25 is fixedly connected to the upper right side of the foot-shaped cylinder 1. The upper pull bracket 24 and the guide rod 25 are slidably connected. The fifth elastic element 26 is connected between the upper pull bracket 24 and the guide rod 25.

[0041] By setting up a drainage mechanism, the treated medication can be drained more easily without the patient needing to put on and take off the device. The specific operation is as follows: After soaking treatment, the staff pulls the upper pull frame 24 upward, causing the fifth elastic element 26 to deform. The upward sliding of the upper pull frame 24 drives the blocking block 23 upward. After the blocking block 23 moves upward, it no longer blocks the drain pipe 22. At this time, the medication in the foot-shaped cylinder 1 can be drained through the drain pipe 22. After the medication is drained, the staff releases the upper pull frame 24. Under the action of the fifth elastic element 26 resetting, the upper pull frame 24 drives the blocking block 23 downward to reset. After the blocking block 23 moves downward, it re-blocks the drain pipe 22, so that the negative pressure machine 8 can perform negative pressure treatment on the patient's foot. In this way, the treated medication can be drained more easily without the patient needing to put on and take off the device.

[0042] like Figure 1 , Figure 10 and Figure 11 As shown, it also includes a reinforcing mechanism, which can reinforce the connection between the foot-shaped cylinder 1 and the cover cylinder 2. The reinforcing mechanism includes a second water pipe 27, a push block 28, and a locking block 29. The piston cylinder 3 is connected to the lower side of the second water pipe 27. A square frame is fixedly connected to the lower front side of the cover cylinder 2. The tail end of the second water pipe 27 is connected to the square frame at the lower front side of the cover cylinder 2. The push block 28 is slidably connected inside the square frame at the lower front side of the cover cylinder 2. The locking blocks 29 are symmetrically connected inside the square frame at the lower front side of the cover cylinder 2. The right end of the push block 28 is conical. The upper and lower sides of the locking blocks 29 are inclined. The push block 28 and the locking blocks 29 are pressed together.

[0043] By setting up a reinforcement mechanism, the connection between the foot-shaped cylinder 1 and the cover cylinder 2 can be reinforced. The specific operation is as follows: When the piston rod 4 slides downward, it squeezes the liquid in the piston cylinder 3 into the second water pipe 27. The liquid in the second water pipe 27 enters the square frame at the lower front side of the cover cylinder 2, which in turn squeezes the push block 28 to slide to the right. The push block 28 slides to the right and squeezes the locking block 29 to slide backward. After the locking block 29 slides backward, it extends out of the square frame and locks the foot-shaped cylinder 1, thereby achieving the purpose of reinforcing the connection between the foot-shaped cylinder 1 and the cover cylinder 2. When the piston rod 4 slides upward, the liquid in the square frame can be sucked back into the piston cylinder 3 through the second water pipe 27. The push block 28 will also slide to the left to reset. At this time, the cover cylinder 2 opens, causing the locking block 29 to be squeezed by the foot-shaped cylinder 1 and slide backward into the square frame. In this way, the connection between the foot-shaped cylinder 1 and the cover cylinder 2 can be reinforced to avoid liquid leakage.

[0044] like Figure 9 As shown, it also includes an adjustment mechanism that can adjust the height of the foot plate 13. The adjustment mechanism includes a compression block 30 and a threaded rod 31. The compression block 30 is slidably connected to the lower part of the foot cylinder 1. The compression block 30 is in compression fit with the foot plate 13. The lower right part of the foot cylinder 1 is connected to the threaded rod 31 by a thread. The left end of the threaded rod 31 is rotatably connected to the compression block 30.

[0045] The height of the foot plate 13 can be adjusted by setting an adjustment mechanism to adapt to the size of different patients' feet, avoiding the device not fitting the patient's foot and affecting movement. The specific operation is as follows: the operator controls the threaded rod 31 to rotate as needed. While the threaded rod 31 rotates, it will move to the right and left, thereby driving the squeezing block 30 to move left and right. When the squeezing block 30 moves to the right, it will squeeze the foot plate 13 to slide upward. When the squeezing block 30 slides to the left, it will no longer squeeze the foot plate 13, and the foot plate 13 can slide downward. In this way, the height of the foot plate 13 can be adjusted as needed to adapt to the size of different patients' feet.
