Description

Technical Field

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

[0002] Diabetic foot is one of the most common and serious complications of diabetes. It is mainly caused by poor blood sugar control, which leads to peripheral nerve and vascular lesions, resulting in symptoms such as foot ulcers, infections, and gangrene. If the wound is not cleaned in time or thoroughly, the condition can easily worsen and may even require amputation.

[0003] Currently used debridement devices for diabetic foot generally have many shortcomings: First, the limb fixation structure has a single function, which can only provide simple support and cannot adjust the height, horizontal position, leg flexion and extension, and foot rotation of the patient's lower limb in multiple dimensions. This results in insufficient exposure of the toes, soles, heels, and sides of the feet, affecting the debridement operation. Second, the position and angle of the irrigation device are fixed, with poor flexibility, making it difficult to accurately irrigate the dead corners of the wound. Moreover, the temperature and flow rate of the irrigation fluid are uncontrollable, which can easily cause discomfort to the patient. Third, the waste fluid is collected mixed with necrotic tissue, resulting in poor solid-liquid separation, which can easily cause environmental pollution and cross-infection, and increase the difficulty of cleaning for medical staff. Summary of the Invention

[0004] To address the technical deficiencies in the prior art, this invention proposes a debridement device for rinsing diabetic foot wounds, which solves the aforementioned technical problems and meets practical needs.

[0006] As an improvement to the above solution, the end of the leg support bracket is fixed with a rotating connecting shaft, and the ankle rotating bracket is sleeved on the outside of the rotating connecting shaft and rotatably connected to the rotating connecting shaft on the same axis, forming a rotating pair in which the ankle rotating bracket can rotate circumferentially relative to the leg support bracket; the second locking member is a locking bolt, which is radially inserted into the ankle rotating bracket and tightly fitted with the rotating connecting shaft to lock the circumferential rotation angle of the ankle rotating bracket.

[0007] As an improvement to the above solution, the flushing assembly includes a column support, a horizontal cantilever, an angle-adjusting gimbal, a flushing nozzle, a constant-temperature liquid tank, a booster pump, a delivery hose, and a flow regulating valve.

The constant temperature medicine tank and the booster pump are both fixed inside the base frame. The water inlet of the booster pump is connected to the constant temperature medicine tank through a pipeline, and the water outlet is connected to the flushing nozzle through the delivery hose. A flow regulating valve is connected in series on the delivery hose.

[0009] As an improvement to the above solution, the transverse cantilever is provided with a horizontal sliding groove along its length, the upper part of the column support is provided with a sliding locking block that matches the horizontal sliding groove, and the flushing nozzle is provided with an anti-clogging micro filter.

The interior of the open liquid collection hood is provided with a primary filter screen and a secondary interception screen from top to bottom. The primary filter screen is inclined and its lower end corresponds to the inlet of the solid waste storage box. The solid waste storage box is slidably inserted into the side wall of the waste liquid storage tank. The waste liquid storage tank is located below the open liquid collection hood and is fixedly connected to the base frame. The drain pipe is fixedly connected to the lower side wall of the waste liquid storage tank and is equipped with a sealing valve.

Detailed Implementation

[0020] The embodiments of the present invention will be described below with reference to the accompanying drawings and related examples. The embodiments of the present invention are not limited to the following examples, and the present invention relates to the relevant necessary components in this technical field, which should be regarded as well-known technology in this technical field and can be known and mastered by those skilled in this technical field.

[0021] This technical solution discloses a debridement device for rinsing diabetic foot wounds, including a base frame 1, an adjustable limb fixation component 2, a rinsing component 5, and a graded filtration waste liquid collection component 6. In the technical solution of the base frame 1, the base frame 1 is the structural support structure of the overall debridement device. This solution is made of rigid material structure welded together, so that its structure is stable and can be used to fix the adjustable limb fixation component 2, the rinsing component 5 and the graded filtration waste liquid collection component 6, so as to ensure that the device remains stable during the debridement operation without shaking or displacement, providing a stable installation carrier for each functional component and ensuring that the entire debridement process is safe and reliable.

[0022] Furthermore, in the above scheme, the top of the base bracket is fixed with the graded filtration waste liquid collection component 6 and the adjustable limb fixing component 2. The adjustable limb fixing component 2 is arranged adjacent to the graded filtration waste liquid collection component 6 and extends to the top of the graded filtration waste liquid collection component 6. The flushing component 5 is fixedly connected to the base frame 1 adjacent to the graded filtration waste liquid collection component 6 and spans above the adjustable limb fixing component 2. In the technical solution of the adjustable limb fixation component 2, the adjustable limb fixation component 2 includes a leg support 21, an ankle rotation bracket 22, a foot positioning plate 23, a lifting support 24, a horizontal rotation seat 25, a pitch adjustment structure 3, a first locking member 34, and a second locking member 26. The adjustable limb fixation component 2 can be used for multi-position positioning and stable fixation of the patient's lower limbs and feet. The pitch adjustment structure 3 enables the leg support 21 to pitch up and down, adjusting the inclination angle of the lower leg. The ankle rotation bracket 22 enables the foot to rotate circumferentially, fully exposing the wound. The first locking member 34 and the second locking member 26 respectively lock the pitch angle and rotation angle, preventing limb displacement during debridement and improving operational safety.

[0023] Furthermore, in the above scheme, the bottom end of the lifting support column 24 is fixedly connected to the base frame 1, and the top end of the lifting support column 24 is rotatably connected to the horizontal rotating seat 25. The upper part of the horizontal rotating seat 25 is hinged to the leg support 21 through the pitch adjustment structure 3. The lifting support column 24 realizes overall height adjustment, which can adapt to patients of different heights. After the horizontal rotating seat 25 is installed, it can be horizontally adjusted and rotated, which makes it convenient for the operator to switch the operating position.

[0024] Furthermore, in the above scheme, the end of the leg support 21 is coaxially rotatably connected to the ankle rotating bracket 22, and the end of the ankle rotating bracket 22 is vertically fixedly connected to the foot positioning plate 23; the leg support 21, the ankle rotating bracket 22, and the foot positioning plate 23 are all arc-shaped medical silicone soft pad structures, and the flexible fixing strap 4 is an elastic Velcro strap.

[0025] The leg support 21 has an overall arc-shaped concave structure, which is adapted to the physiological curve of the human calf. It is made of medical-grade silicone soft pad material, with a smooth surface and flexible cushioning effect. Flexible fixing straps 4 are symmetrically arranged on both sides of the leg support 21 along the length direction. The flexible fixing straps 4 are elastic Velcro straps, which can realize length adjustment and quick adhesion and fixation. A rotating connecting shaft 27 is fixedly arranged at the end of the leg support 21. The rotating connecting shaft 27 is arranged laterally in the horizontal direction to provide a rotating support base for the ankle rotating bracket 22.

[0026] The ankle rotation bracket 22 has a ring-shaped structure and is coaxially sleeved on the outside of the rotating connecting shaft 27, forming a clearance fit rotating pair with the rotating connecting shaft 27. It can rotate around the rotating connecting shaft 27. The ankle rotation bracket 22 also adopts an arc-shaped flexible pad structure to fit the contour of the human ankle, and the surface is also provided with a flexible fixing strap 4.

[0027] The foot positioning plate 23 has a flat plate structure and is fixedly connected perpendicularly to the end of the ankle rotation bracket 22 to form an L-shaped support structure for supporting the patient's foot. The surface of the foot positioning plate 23 is also provided with a flexible fixing strap 4 to achieve stable restraint and fixation of the foot.

[0028] It should be noted that the leg support 21, ankle rotation bracket 22, and foot positioning plate 23 all adopt an arc-shaped medical silicone soft pad structure, which conforms to the physiological curve of the human lower limb and foot, improves patient comfort, and prevents local compression of the limb. The leg support 21, ankle rotation bracket 22, and foot positioning plate 23 work together to form a continuous support structure, supporting the lower leg, ankle, and foot respectively. The flexible fixing strap 4 adopts an elastic Velcro structure, which can quickly fix the limb and is adjustable in tightness, ensuring reliable fixation without affecting blood circulation.

[0029] Furthermore, in the above technical solution, the end of the leg support 21 is fixed with a rotating connecting shaft 27, and the ankle rotating bracket 22 is sleeved on the outside of the rotating connecting shaft 27 and is coaxially rotatably connected to the rotating connecting shaft 27, forming a rotating pair in which the ankle rotating bracket 22 can rotate circumferentially relative to the leg support 21. The ankle rotation bracket 22 is provided with a second locking member 26 for adjusting and locking. The second locking member 26 is a locking bolt. The second locking member 26 is radially inserted through the ankle rotation bracket 22 and is tightly engaged with the rotating connecting shaft 27 to lock the circumferential rotation angle of the ankle rotation bracket 22.

[0030] It should be noted that the ankle rotation bracket 22 is coaxially rotatably connected to the leg support bracket 21 via the rotation connecting shaft 27, which can drive the foot positioning plate 23 to rotate circumferentially, realize the inward and outward rotation adjustment of the toes, and fully expose the difficult-to-operate areas such as the arch, heel, and side of the foot. The second locking member 26 adopts a radial locking bolt, which tightens the rotation connecting shaft 27 to achieve angle locking, ensuring the stability of the foot posture, without the need for medical staff to manually support the foot.

[0031] The ankle rotating bracket 22 has a threaded through hole in the radial direction. The second locking member 26 is screwed into the threaded through hole and passes through the ankle rotating bracket 22 in the radial direction. The inner end of the locking bolt is facing the outer wall of the rotating connecting shaft 27 to form a tight fit structure. When the locking bolt is tightened, the inner end of the bolt presses against the outer wall of the rotating connecting shaft 27, and the circumferential rotation of the ankle rotating bracket 22 is restricted by friction, thereby locking and fixing the foot rotation angle. When the locking bolt is loosened, the tightening force disappears, and the ankle rotation bracket 22 can rotate freely around the rotating connecting shaft 27 to achieve adjustment of the inward and outward rotation angles of the foot. The second locking member 26, the ankle rotation bracket 22, and the rotating connecting shaft 27 form an independent locking structure, which can work independently of the locking of the pitch adjustment structure 3 to achieve separate locking of the leg pitch angle and the foot rotation angle.

[0032] In the technical solution of the pitch adjustment structure 3, the pitch adjustment structure 3 is provided with a first locking member 34 for adjusting and locking. The pitch adjustment structure 3 includes a hinge fixing seat 31, a hinge rotating arm 32 and a hinge shaft 33. The hinge fixing seat 31 is fixedly connected to the upper part of the horizontal rotating seat 25, and the hinge rotating arm 32 is fixedly connected to the lower part of the leg support 21. The hinge fixing seat 31 and the hinge rotating arm 32 are hinged through the hinge shaft 33 to form a rotating pair in which the leg support 21 can pitch and rotate relative to the horizontal rotating seat 25. The first locking element 34 is a locking knob. The first locking element 34 is threadedly connected to the hinge shaft 33 and is used to lock the relative rotation angle between the hinge fixing seat 31 and the hinge rotating arm 32, so as to realize stepless adjustment of the lower leg support angle. The first locking element 34 is threadedly connected to the hinge shaft 33 by a locking knob. Tightening it can lock the relative rotation of the hinge, so that the leg support 21 is kept at the set angle to meet the needs of different wound exposure.

[0033] The hinge fixing seat 31 is a fixed support component, its bottom is fixedly connected to the upper end face of the horizontal rotating seat 25, and its top is provided with a hinge ear plate. The hinge rotating arm 32 is a rotating component. Its upper end is fixedly connected to the lower part of the leg support 21, and its lower end is provided with a hinge ear seat that cooperates with the hinge ear plate.

[0034] The hinge shaft 33 is horizontally inserted into the interior of the hinge ear plate and the hinge ear seat, and hinges the hinge fixing seat 31 and the hinge rotating arm 32 to form a rotating pair, so that the leg support 21 can rotate up and down relative to the horizontal rotating seat 25 around the hinge shaft 33. The first locking element 34 is a locking knob, which is located at the end of the hinge shaft 33 and connected to the hinge shaft 33 by a threaded engagement. When the locking knob is tightened, the hinge ear plate and the hinge ear seat can be axially pressed to increase the frictional resistance and realize the locking and fixing of the relative rotation angle between the hinge fixing seat 31 and the hinge rotating arm 32. When the locking knob is loosened, the locking can be released, and the pitch angle can be freely adjusted.

[0035] In the technical solution of the irrigation component 5, the irrigation component 5 includes a column support 51, a horizontal cantilever 52, an angle adjustment gimbal 53, an irrigation nozzle 54, a constant temperature medicine tank 55, a booster pump 551, a delivery hose 552, and a flow regulating valve, which are used to provide constant temperature, controllable, and directional wound irrigation.

[0036] Furthermore, in the above scheme, the bottom end of the column support 51 is fixedly connected to the base frame 1, serving as the vertical support for the entire rinsing mechanism. The top end of the column support 51 is connected to the horizontal cantilever 52. The column support 51 and the horizontal cantilever 52 enable adjustment of the rinsing height and horizontal position. The end of the horizontal cantilever 52 away from the column support 51 is fixedly connected to the angle adjustment platform 53. The lower end of the angle adjustment platform 53 is detachably connected to the rinsing nozzle 54. The angle adjustment platform 53 can drive the rinsing nozzle 54 to achieve multi-angle free adjustment of up and down tilt and left and right rotation. Furthermore, in the above scheme, the constant temperature medicine tank 55 and the booster pump 551 are both fixed inside the base frame 1. The water inlet of the booster pump 551 is connected to the constant temperature medicine tank 55 through a pipeline, and the water outlet is connected to the irrigation nozzle 54 through the delivery hose 552. A flow regulating valve is connected in series on the delivery hose 552. The constant temperature medicine tank 55 ensures that the irrigation fluid temperature is suitable, improving the patient's tolerance. The booster pump 551 provides stable irrigation pressure, and the flow regulating valve can adjust the flow rate according to the wound condition, providing the wound with constant temperature, controllable, and directional irrigation fluid. The irrigation height, horizontal position, and spray angle can be freely adjusted to achieve precise irrigation of the wound without dead angles.

[0037] Furthermore, in the above-described design, the transverse cantilever 52 is provided with a horizontal sliding groove 521 along its length, and the upper part of the column support 51 is provided with a sliding locking block 511 that matches the horizontal sliding groove 521. The sliding locking block 511, in conjunction with the horizontal locking block, enables horizontal extension and retraction adjustment and positioning locking. The flushing nozzle 54 is equipped with an anti-clogging micro-filter, which can effectively filter impurities and prevent nozzle clogging. The overall structure is flexible in adjustment and convenient in operation, significantly improving the accuracy and safety of wound cleaning and flushing.

[0038] In the technical solution of the graded filtration waste liquid collection assembly 6, the graded filtration waste liquid collection assembly 6 includes an open collection hood 61, a primary filter screen 62, a secondary interception screen 63, a waste liquid storage tank 64, a solid waste collection box 65, a drain pipe 66, and a sealing valve 67.

[0039] As an improvement to the above solution, the upper edge of the open liquid collection hood 61 surrounds the lower part of the adjustable limb fixing component 2 and is fixedly connected to the base frame 1, for omnidirectional collection of waste liquid and dirt generated during the rinsing process. The open liquid collection hood 61 is provided with a primary filter screen 62 and a secondary interception screen 63 from top to bottom. The primary filter screen 62 is inclined and its lower end corresponds to the inlet of the solid waste storage box 65. The solid waste storage box 65 is slidably inserted into the side wall of the waste liquid storage tank 64 and can be freely pulled out and disassembled. The waste liquid storage tank 64 is located below the open liquid collection hood 61 and is fixedly connected to the base frame 1. The drain pipe 66 is fixedly connected to the lower side wall of the waste liquid storage tank 64, and a sealing valve 67 is provided on the drain pipe 66. It should be noted that the graded filtration waste collection component 6 performs rapid graded filtration and solid-liquid separation on the waste fluid and necrotic tissue generated during wound cleaning. The primary filter 62 can effectively intercept larger solid contaminants such as blood clots and necrotic tissue, which automatically slide into the solid waste collection box 65 along the inclined surface. The secondary interception net 63 further filters out tiny impurities, improving the cleanliness of the waste fluid. The filtered waste fluid flows into the waste fluid storage tank 64 for centralized storage and unified treatment. The solid-liquid separation structure can prevent contaminants from clogging the pipeline, reduce environmental pollution, and lower the risk of cross-infection. At the same time, it facilitates medical staff in cleaning up medical waste, improving the hygiene and convenience of the device.

[0040] The above description is only a preferred embodiment of the present invention. It should be noted that those skilled in the art can make several improvements and modifications without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
