Description

Technical Field

[0001] This invention belongs to the field of debridement device technology, and specifically relates to a debridement device for diabetic foot. Background Technology

[0002] The foot is a complex target organ for diabetes, a multi-system disease. When debridement wounds in diabetic foot patients, it is necessary to thoroughly remove necrotic tissue and exudate from the wound surface, control ulcer symptoms, and prevent further aggravation of the ulcer. Currently, specialized devices are typically used to assist in debridement.

[0003] In existing technologies, devices are commonly used to immobilize the patient's leg. However, the area requiring debridement is mostly the toes, and existing technologies cannot assist in separating the toes, which is a limitation. For example, patent publication number CN116158960B, published on 2023-06-30, discloses a debridement device for diabetic feet. This device only clamps the patient's leg with a clamping rod and cannot assist in separating the toes.

[0004] For example, the patent with publication number CN115813687A and publication date of 2023-03-21 discloses a debridement device for diabetic foot. Similarly, this debridement device for diabetic foot only fixes the patient's foot with the first arch frame and the second arch frame, and also cannot help separate the patient's toes.

[0005] In view of the shortcomings of the existing technology, a wound cleaning device for diabetic foot is designed to overcome the shortcomings of the existing technology. It can help separate the patient's toes without the need for doctors to use tools to separate them and is easy to operate. Summary of the Invention

[0006] In order to overcome the limitations of the existing technology, which only clamps the patient's leg and cannot help separate the patient's toes, the present invention aims to provide a debridement device for diabetic foot that can help separate the patient's toes without the need for doctors to use hand tools, and is easy to operate.

[0007] To address the aforementioned technical problems, this invention provides a debridement device for diabetic foot, comprising a base, a foot support plate, a shielding frame, a spraying mechanism, a bearing seat, a telescopic rod, a support frame, levers, and a fine-tuning component. The base has an arc-shaped foot support plate in its center, with a heel support hole on the left side. A rubber strip is attached to the edge of the heel support hole on the foot support plate. Two opposing shielding frames are rotatably mounted on the upper part of the base. A spraying mechanism for spraying medication onto the patient's foot is located between the base and the shielding frames. A bearing seat is slidably mounted on the upper left side of the base. A telescopic rod is rotatably mounted on the upper part of the bearing seat, and a support frame is mounted on the telescopic rod. Two opposing levers are slidably mounted on the upper part of the support frame. A fine-tuning component is located between the support frame and the levers, adjusting the two levers to separate the patient's toes.

[0008] Preferably, the spraying mechanism includes a nozzle, a water pump, and a hose. The nozzle is embedded in the left side of the shielding frame and faces the heel support hole on the foot support plate. The water pump for connecting an external medicine tank is installed on the left side of the base by means of screw connection. A hose connects the output pipe of the water pump to the nozzle.

[0009] Preferably, the telescopic rod includes a sleeve, a lead screw, and a nut.

The support frame is connected to the left end of the lead screw. The lead screw slides with the sleeve through a square support rod built into the sleeve. The nut is rotatably mounted on the left side of the sleeve and threadedly connected to the lead screw. The outer side of the nut has anti-slip stripes.

[0010] Preferably, the fine-tuning component includes a sliding frame, a connecting rod, and a second lead screw. The sliding frame is slidably provided in the middle of the support frame, and a connecting rod is rotatably provided between the sliding frame and the lever. The second lead screw is rotatably provided in the middle of the support frame and is threadedly connected to the sliding frame. The second lead screw is vertically arranged, and a rubber handle is connected to the lower end of the second lead screw.

[0011] Preferably, it also includes a guide frame, a toothed plate, an adaptive telescopic gripper, a first gear, a rotating shaft, and a second gear. The right front side of the foot support plate is connected to the guide frame. The upper part of the guide frame is slidably provided with an L-shaped toothed plate. The teeth of the toothed plate are located on the lower middle side of the toothed plate. The ends of the two toothed plates that are close to each other are provided with adaptive telescopic grippers for clamping the patient's foot. The middle part of the guide frame is rotatably provided with a first gear that meshes with the toothed plate. The front and rear first gears mesh with the front and rear toothed plates respectively. The lower part of the shielding frame is connected to a rotating shaft that is rotatably connected to the base. The right side of the rotating shaft is connected to a second gear that meshes with the first gear. The front and rear second gears mesh with the front and rear first gears respectively. The diameter of the second gear is larger than the diameter of the first gear.

[0012] Preferably, the adaptive telescopic gripper includes guide rods, clamping plates, and elastic elements. Two guide rods are slidably provided at the ends of the two toothed plates that are close to each other. An arc-shaped clamping plate is connected between the ends of the two opposing guide rods that are close to the foot support plate. An elastic element, which is a connecting spring, is connected between the clamping plate and the toothed plates and surrounds the guide rods.

[0013] Preferably, it also includes a hinge block and a cylinder. The hinge block is slidably provided on the side of the two shielding frames that are far apart from each other. The cylinders are installed on both sides of the front side of the base by means of screw connection. The pistons of the front and rear cylinders are respectively connected to the front and rear hinge blocks in a hinge manner.

[0014] Preferably, it also includes a guide plate, a filter frame, and a suction pump. A guide plate that slopes downward to the right is connected between the two inner sides of the lower part of the base. The guide plate is located directly below the foot support plate. The lower end of the guide plate is bent into a U-shape. A filter frame for filtering necrotic tissue is slidably provided at the lower end of the guide plate. A suction pump is installed on the lower right side of the base by means of screw connection. The suction pipe of the suction pump passes through the guide plate and extends directly below the filter frame.

[0015] Preferably, it also includes a second cylinder, a bellows, and a sealing ring. The lower part of the base is connected by screws to a second cylinder that passes through the guide plate. The piston of the second cylinder is connected to the lower side of the foot support plate. The second cylinder is used to adjust the height of the foot support plate. The lower part of the base is connected to the guide plate by a bellows surrounding the second cylinder. The bellows passes through the guide plate, and a sealing ring made of rubber is connected to the part of the guide plate through which the bellows passes.

[0016] Preferably, the spraying mechanism also includes a heater and a heat-conducting pipe. The heater is installed on the left side of the base by means of screw connection. The heating element of the heater is connected to the heat-conducting pipe. The heat-conducting pipe surrounds the output pipe of the water pump. The hose is made of stainless steel. The heater preheats the output pipe of the water pump through the heat-conducting pipe, thereby preheating the liquid medicine.

[0017] In addition to overcoming the shortcomings of existing technologies, this invention also achieves the following beneficial effects: 1. The position of the levers can be adjusted in various ways to easily align with the patient's toes. By moving the two levers apart, the patient's toes can be spread apart, making it easier to clean and treat the wound without the doctor having to hold them all the time, making the operation convenient.

[0018] 2. When the shielding frame is rotated open, the splint will automatically and synchronously clamp the patient's leg. The elastic element adapts to the deformation, which can clamp legs of different sizes, improve stability, and prevent the patient from moving their feet during wound cleaning.

[0019] 3. The second control cylinder can drive the foot support plate to move up and down, thereby adjusting the height of the foot support plate. It can be used in a variety of ways. The bellows can prevent necrotic tissue and exudate from flowing onto the second control cylinder. Attached Figure Description

[0030] Example 1: A debridement device for diabetic foot, such as Figures 1-8 As shown, the device includes a base 1, a foot support plate 2, a shielding frame 3, a spraying mechanism 4, a bearing seat 51, a telescopic rod 52, a support frame 53, a lever 54, and a fine-tuning component 55. The base 1 has an arc-shaped foot support plate 2 in the middle. The left side of the foot support plate 2 has a heel support hole. A rubber strip is attached to the edge of the heel support hole on the foot support plate 2. The upper part of the base 1 has two shielding frames 3 that are opposite each other. A spraying mechanism 4 for spraying medicine on the patient's feet is located between the base 1 and the shielding frames 3. The upper left side of the base 1 has a slidable bearing seat 51. The upper part of the bearing seat 51 has a telescopic rod 52 that is rotatable. The telescopic rod 52 has a support frame 53. The upper part of the support frame 53 has two levers 54 that are opposite each other. A fine-tuning component 55 is located between the support frame 53 and the levers 54. The fine-tuning component 55 adjusts the two levers 54 to separate the patient's toes.

[0031] like Figures 1-3 As shown, the spraying mechanism 4 includes a nozzle 41, a water pump 42, and a hose 43. The nozzle 41 is embedded in the left side of the shielding frame 3, facing the heel support hole on the foot support plate 2. The water pump 42 for connecting an external medicine tank is installed on the left side of the base 1 by means of screw connection. The output pipe of the water pump 42 is connected to the nozzle 41 by a hose 43.

[0032] like Figures 2-4 As shown, the telescopic rod 52 includes a sleeve 521, a lead screw 522, and a nut 523. The upper part of the bearing seat 51 is rotatably provided with the sleeve 521, and the left part of the sleeve 521 is slidably provided with the lead screw 522. The support frame 53 is connected to the left end of the lead screw 522. The lead screw 522 is slidably engaged with the sleeve 521 through the built-in square support rod. The left part of the sleeve 521 is rotatably provided with a nut 523 that is threadedly connected to the lead screw 522. The outer side of the nut 523 has anti-slip stripes.

[0033] like Figure 2 and Figure 3As shown, the fine-tuning component 55 includes a sliding frame 551, a connecting rod 552, and a second lead screw 553. The sliding frame 551 is slidably provided in the middle of the support frame 53. The connecting rod 552 is rotatably provided between the sliding frame 551 and the lever 54. The second lead screw 553 is rotatably provided in the middle of the support frame 53 and is threadedly connected to the sliding frame 551. The second lead screw 553 is vertically arranged, and a rubber handle is connected to the lower end of the second lead screw 553.

[0034] The operator can apply the corresponding technical solutions in this device to the debridement of diabetic foot according to the specific situation. When this device is needed to assist in the debridement of diabetic foot, firstly, rotate the shielding frame 3 to open it, so that the patient places their foot on the foot support plate 2. The patient's heel is inserted into the heel support hole of the foot support plate 2. Then, rotate the telescopic rod 52 upward by 90 degrees, so that the telescopic rod 52 drives the lever 54 to approach the patient's toes through the support frame 53. Then, move the bearing seat 51 back and forth to adjust the position of the lever 54. Rotate the nut 523, which will drive the screw 1 522 to rise and fall, thereby adjusting the height of the lever 54, so that the two rods can be inserted into the patient's toes. In the gap between the two toes that need cleaning, rotate screw 2 553, causing screw 2 553 to move sliding frame 551 to the right. Sliding frame 551 will move lever 54 outward through connecting rod 552. The two levers 54 will move away from each other, thus spreading the patient's toes apart, making it easier to clean the patient's toes without the doctor having to hold them. After the patient's toes are spread apart, rotate the shielding frame 3 in the opposite direction to close it, so that the water pump 42 is connected to the external medicine tank. Control the water pump 42 to draw the medicine in the medicine tank into the hose 43. The medicine in the hose 43 will be sprayed out from the nozzle 41 to treat the patient's foot. At the same time, the shielding frame 3 can prevent the medicine from spreading too quickly and ensure that the medicine can fully adhere to the patient's foot.

[0035] Example 2: Based on Example 1, such as Figures 5-7 As shown, it also includes a guide frame 61, a toothed plate 62, an adaptive telescopic gripper 63, a first gear 64, a rotating shaft 31, and a second gear 65. The right front side of the foot support plate 2 is connected to both sides of the guide frame 61. The upper part of the guide frame 61 is slidably provided with an L-shaped toothed plate 62. The teeth of the toothed plate 62 are located on the lower side of the middle part of the toothed plate 62. The ends of the two toothed plates 62 that are close to each other are provided with adaptive telescopic grippers 63 for clamping the patient's foot. The middle part of the guide frame 61 is rotatably provided with a first gear 64 that meshes with the toothed plate 62. The front and rear first gears 64 mesh with the front and rear toothed plates 62 respectively. The lower part of the shielding frame 3 is connected to a rotating shaft 31 that is rotatably connected to the base 1. The right side of the rotating shaft 31 is connected to a second gear 65 that meshes with the first gear 64. The front and rear second gears 65 mesh with the front and rear first gears 64 respectively. The diameter of the second gear 65 is larger than the diameter of the first gear 64.

[0036] like Figure 6 As shown, the adaptive telescopic gripper 63 includes guide rods 631, clamping plates 632, and elastic elements 633. Two guide rods 631 are slidably provided at the ends of the two toothed plates 62 that are close to each other. An arc-shaped clamping plate 632 is connected between the ends of the two opposing guide rods 631 that are close to the foot support plate 2. An elastic element 633, which is a connecting spring, is connected between the clamping plate 632 and the toothed plates 62 and surrounds the guide rods 631.

[0037] like Figure 1 and Figure 5 As shown, it also includes a hinge block 71 and a cylinder 72. The hinge block 71 is slidably provided on the side of the two shielding frames 3 that are far apart from each other. The cylinder 72 is installed on both sides of the front side of the base 1 by means of screw connection. The pistons of the front and rear cylinders 72 are respectively connected to the front and rear hinge blocks 71 in a hinge manner.

[0038] When the piston of cylinder 72 contracts, it drives the shielding frame 3 to rotate and open via hinge block 71. The shielding frame 3 then drives gear 65 to rotate via shaft 31 and mesh with gear 64. Gear 64 rotates and meshes with toothed plate 62. The front and rear toothed plates 62 respectively drive the front and rear adaptive telescopic grippers 63 to move closer together. The gripper 632 clamps the patient's leg, and the elastic element 633 deforms adaptively to clamp legs of different sizes, thus preventing the patient's foot from moving during wound cleaning. When the shielding frame 3 rotates in the opposite direction to close, gear 65 rotates in the opposite direction to mesh with gear 64. The front and rear toothed plates 62 then drive the front and rear adaptive telescopic grippers 63 to move away from each other, thus releasing the patient's foot.

[0039] Example 3: Based on Example 1, such as Figure 8 As shown, it also includes a guide plate 11, a filter frame 12, and a suction pump 13. The lower part of the base 1 is connected between the front and rear inner sides, with the guide plate 11 tilted downward to the right. The guide plate 11 is located directly below the foot support plate 2. The lower end of the guide plate 11 is bent into a U-shape. The lower end of the guide plate 11 is slidably provided with a filter frame 12 for filtering necrotic tissue. The lower right side of the base 1 is equipped with a suction pump 13 by means of screw connection. The suction tube of the suction pump 13 passes through the guide plate 11 and extends directly below the filter frame 12.

[0040] The necrotic tissue and exudate generated during wound cleaning will fall onto the guide plate 11. The guide plate 11 will guide the impurities to the filter frame 12, which will filter the necrotic tissue. At this time, the suction pump 13 can be controlled to suck out the exudate for collection. Then the filter frame 12 is pulled out, which makes it easy to clean the necrotic tissue and exudate generated during wound cleaning and avoids soiling the working environment.

[0041] like Figure 8 As shown, it also includes a second cylinder 81, a bellows 82, and a sealing ring. The lower part of the base 1 is connected by screws to a second cylinder 81 that passes through the guide plate 11. The piston of the second cylinder 81 is connected to the lower side of the foot support plate 2. The second cylinder 81 is used to adjust the height of the foot support plate 2. The lower part of the base 1 is connected to the bellows 82 that surrounds the second cylinder 81. The bellows 82 passes through the guide plate 11. A sealing ring made of rubber is connected to the part of the guide plate 11 through which the bellows 82 passes.

[0042] The control cylinder 81 can drive the foot support plate 2 to move up and down, thereby adjusting the height of the foot support plate 2. The bellows 82 can prevent necrotic tissue and exudate from flowing onto the cylinder 81.

[0043] like Figure 1 and Figure 2 As shown, the spraying mechanism 4 also includes a heater 44 and a heat pipe 45. The heater 44 is installed on the left side of the base 1 by means of screw connection. The heat pipe 45 is connected to the heating element of the heater 44. The heat pipe 45 surrounds the output pipe of the water pump 42. The hose 43 is made of stainless steel. The heater 44 preheats the output pipe of the water pump 42 through the heat pipe 45, thereby preheating the liquid medicine.

[0044] The output pipe of the water pump 42 is preheated by the heater 44 and the heat pipe 45, thereby preheating the medicine solution and avoiding discomfort to the patient caused by the medicine solution being too cold.

[0045] The embodiments described above are merely preferred embodiments of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications, improvements, and substitutions without departing from the concept of the present invention, and these all fall within the scope of protection of the present invention. Therefore, the scope of protection of this patent should be determined by the appended claims.
