Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of wound care, in particular to a wound dressing care device for debridement of a wound. BACKGROUND

[0002] In the process of debridement and dressing care of extremity wounds, maintaining the stability of the affected limb is a key link to ensure smooth operation, alleviate the patient's pain and promote wound healing. If the affected limb moves or shifts unexpectedly during disinfection, medication or bandaging, it may not only exacerbate the patient's pain and cause protective limb contraction, but also lead to inaccurate dressing placement, uneven drug application, and even secondary wound contamination, affecting healing.

[0003] To improve the stability of the care process, some devices for auxiliary fixation and automatic operation have appeared in the prior art. For example, the Chinese invention patent with publication number CN115363862B discloses a wound dressing care device for debridement of a wound, which comprises a base plate and an L-shaped plate, the upper end face of the base plate is fixedly connected with the L-shaped plate, and the upper end face of the L-shaped plate is installed with an automatic extrusion and application mechanism. The wound dressing care device for debridement of a wound solves the problem that when the leg or arm is debrided and dressed, if the wound is directly extruded and applied, the patient will feel pain and the limb will resist unconsciously, causing discomfort to the patient, and when the gauze is bandaged after care, the gauze is usually torn and pasted on the skin, which is not convenient for quickly winding and pasting the gauze with the two ends of the gauze, which may cause the gauze to fall off and expose the patient's wound to the air, causing dust or bacteria to adhere to the wound.

[0004] However, the above-mentioned device still has certain limitations in actual application, especially in the stability and universality of the affected limb. Specifically: first, the limiting and clamping mechanism mainly realizes the coverage and constraint of the limb through the rotation of the arc-shaped ring. This constraint method may not provide sufficient rigid fixing force when dealing with sudden and large amplitude limb contraction or movement caused by patient's pain, and it is difficult to completely eliminate the displacement of the limb. Second, the spacing adjustment ability between the two clamping parts of the device is limited or inconvenient to adjust, and it is difficult to accurately adapt to the thickness changes of different patients' arms or legs from children to adults and the wound position, and the universality needs to be improved. Third, the fixing method of the device as a whole on the operation table is not optimized, and when debridement, dressing and other operations that may generate a pushing and pulling force are performed, the device itself has the risk of sliding or overturning, thereby affecting the stability of the overall operation.

[0005] Therefore, the skilled in the art proposes a wound dressing care device for debridement of a wound to solve the problems in the background art. SUMMARY

The second pull block is fixedly connected to the top of the vertical rod.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. This invention features a clamping assembly. A first slider slides along a first groove to compress a first spring. During this process, a rotating ring drives a top block to move synchronously within the annular groove along with the first slider. When the top block moves away from the back of the top rod, the second spring rebounds and, through the second slider, drives the top rod and clamping block to move into the annular groove. When the top rod is submerged in the through groove, the patient's arm or leg is placed on top of the bracket and passes through the first and second mounting rings. Then, the first slider is released, the first spring rebounds, and, through the first slider, drives the rotating ring and top block to move in the opposite direction. When the top block contacts the top rod, the top block pushes the top rod towards the center of the first and second mounting rings. When the clamping block is in close contact with the patient's arm or leg, it can clamp and fix it. This design allows the device to clamp and fix the patient's arm or leg, effectively preventing the patient's arm or leg from shaking or shifting and affecting the wound cleaning and dressing process.

[0019] 2. This invention features an adjustment component. Pulling the first pull block outward causes it to slide the third slider outward along the cavity and third groove via a pull rod, compressing the third spring. When the locking block moves outward with the pull rod and moves out of the slot, rotating the pull rod causes the third slider to rotate synchronously. The third slider then drives the rotating shaft to rotate synchronously with the pull rod within the rotating groove, thereby rotating the screw. The second connecting seat slides along the adjustment groove with the rotation of the screw, adjusting the position of the second mounting ring. When the distance between the first and second mounting rings matches the patient's body shape, the first pull block is released, the third spring rebounds, and the pull rod moves inward via the third slider. When the locking block moves inward with the pull rod and inserts into the slot, the pull rod is fixed at the current angle, stopping the screw's rotation and keeping the second mounting ring in its current position. This design allows the device to adjust the distance between the first and second mounting rings, making it suitable for patients of different body types and thus broadening its applicability.

[0020] 3. This invention features a fixing component. The base is placed on the workbench, ensuring the suction cup is tightly fitted to it. Pulling the second pull block upwards causes the piston to slide upwards along the air chamber via the vertical rod. Air is drawn into the air chamber, creating a negative pressure environment. During this process, the fixing block slides upwards synchronously along the vertical rod via the lifting groove. When the fixing block reaches the top of the lifting groove, the vertical rod is rotated, causing the fixing block to rotate synchronously. When the fixing block rotates into the fixing groove, the vertical rod and piston are fixed at the current height, maintaining negative pressure inside the suction cup. Atmospheric pressure then secures the base to the workbench. This design allows the device to be stably fixed to the workbench, effectively preventing tilting or displacement of the device due to patient arm or leg movement, which could affect wound cleaning and dressing procedures.

[0033] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0034] As attached Figure 1 To be continued Figure 9 As shown:

[0035] Example 1:

[0036] This invention provides a wound dressing care device for cleaning wounds, including a base 1. A bracket 2 for placing an arm or leg is fixedly connected to one side of the top of the base 1. A first mounting ring 3 and a second mounting ring 4 are provided on the top of the base 1 on one side of the bracket 2. Both the first mounting ring 3 and the second mounting ring 4 are provided with clamping components 5 for clamping and fixing the arm or leg. The clamping components 5 include an annular groove 51, a through groove 52, a top rod 53, a clamping block 54, a rotating ring 55, a top block 56, a first sliding groove 57, a first slider 58, a first spring 59, a second sliding groove 510, a second slider 511, and a second spring 512. A first connecting seat 6 fixedly connected to the top of the base 1 is fixedly connected to the bottom of the first mounting ring 3, and a second connecting seat 7 movably connected to the base 1 is fixedly connected to the bottom of the second mounting ring 4.

[0037] Furthermore, an annular groove 51 is formed inside the first mounting ring 3 and the second mounting ring 4. A through groove 52 penetrates the inner wall of the annular groove 51 near the center of the first mounting ring 3 and the second mounting ring 4. The push rod 53 is slidably connected to the through groove 52, and its end inside the annular groove 51 is fan-shaped. The clamping block 54 is arc-shaped and fixedly connected to the end of the push rod 53 away from the annular groove 51. The rotating ring 55 is rotatably connected to the annular groove 51. The push block 56 is fan-shaped and fixedly connected to the rotating ring 55 near the center of the first mounting ring 3 and the second mounting ring 4. The first sliding groove 57 is formed on the outer surface of the first mounting ring 3 and the second mounting ring 4 and communicates with the annular groove 51. The first slider 58 is fixed. A first spring 59 is installed inside the first slide groove 57 and its two ends are respectively fixedly connected to one side of the first slider 58 and the inner wall of one side of the first slide groove 57. A second slide groove 510 is opened on one side of the inner wall of the annular groove 51 and is located on one side of the top rod 53. A second slider 511 is fixedly connected to one side of the top rod 53 and slidably connected to the second slide groove 510. A second spring 512 is installed inside the second slide groove 510 and its two ends are respectively fixedly connected to the inner wall of the second slider 511 away from the rotating ring 55 and the inner wall of the second slide groove 510 away from the rotating ring 55. The elastic force of the first spring 59 is greater than the sum of the elastic forces of all the second springs 512.

[0038] Working principle: When applying a wound cleaning dressing to a patient, the first slider 58 slides along the first groove 57 to compress the first spring 59. During this process, the rotating ring 55 drives the top block 56 to move synchronously with the first slider 58 in the annular groove 51. When the top block 56 moves away from the back of the top rod 53, the second spring 512 rebounds and drives the top rod 53 and clamping block 54 to move into the annular groove 51 via the second slider 511. When the top rod 53 is submerged in the through groove 52, the clamping block 54 fits tightly against the inner walls of the first mounting ring 3 and the second mounting ring 4. At this time, the patient's arm or leg is placed on top of the bracket 2 and passes through the first mounting ring 3 and the second mounting ring 4. Then, the first slider 58 is released, and the first spring 59 rebounds and drives the rotating ring 55 and the top block 56 to move in the opposite direction via the first slider 58. When the top block 56 contacts the top rod 53, because the top block 56 is fan-shaped... Furthermore, the end of the push rod 53 located within the annular groove 51 is fan-shaped. Therefore, the push block 56 will push the push rod 53 towards the center of the first mounting ring 3 and the second mounting ring 4, and squeeze the second spring 512 through the second slider 511. When the clamping block 54 is in close contact with the patient's arm or leg, it can be clamped and fixed by the rebound force of the first spring 59, thereby avoiding shaking or displacement during debridement or dressing. Then, debridement and dressing can be performed on the patient. After the debridement or dressing is completed, the first slider 58 is slid along the first groove 57 again to squeeze the first spring 59. When the push block 56 moves away from the back of the push rod 53, the second spring 512 rebounds again and drives the push rod 53 and clamping block 54 away from the patient's arm or leg through the second slider 511. Then, the patient can remove their arm or leg from between the first mounting ring 3 and the second mounting ring 4.

[0039] Example 2:

[0040] This embodiment is basically the same as the previous embodiment, except that an adjustment component 8 for adjusting the position of the second mounting ring 4 is provided at the connection between the second connecting seat 7 and the base 1. The adjustment component 8 includes an adjustment groove 81, a screw 82, a rotating groove 83, a rotating shaft 84, a cavity 85, a third sliding groove 86, a connecting groove 87, a pull rod 88, a third slider 89, a third spring 810, a slot 811, a block 812, and a first pull block 813.

[0041] Furthermore, an adjustment groove 81 is formed at the top of the base 1, a second connecting seat 7 is slidably connected to the adjustment groove 81, a screw 82 passes through and is threadedly connected to the second connecting seat 7, a rotating groove 83 is formed on both sides of the inner wall of the adjustment groove 81, a rotating shaft 84 is fixedly connected to both ends of the screw 82 and rotatably connected to the rotating groove 83, a cavity 85 is formed inside a set of rotating shafts 84 away from the bracket 2, a third sliding groove 86 is formed on the top and bottom inner walls of the cavity 85, a connecting groove 87 passes through the inner wall of a set of rotating grooves 83 away from the bracket 2 and communicates with the cavity 85, and a pull rod 88 is movably connected to the connecting groove 87 and its inner end extends to... Inside the cavity 85, the third slider 89 is fixedly connected to the inner end of the pull rod 88 and slidably connected to the third slide groove 86 and the cavity 85. The third spring 810 is sleeved on the outer periphery of the pull rod 88 near the inner end and its two ends are fixedly connected to the inner wall of the third slider 89 away from the screw 82 and the inner wall of the cavity 85 away from the screw 82, respectively. The slot 811 is opened on the inner wall of the base 1 away from the bracket 2 and is distributed in a ring around the outer periphery of the connecting groove 87. The block 812 is fixedly connected to the outer periphery of the pull rod 88 near the outer end and is adapted to the size of the slot 811. The first pull block 813 is fixedly connected to the outer end of the pull rod 88.

[0042] Working principle: When debridement and dressing are required for patients of different body types, the first pull block 813 is pulled outward, causing it to drive the third slider 89 to slide outward along the cavity 85 and the third groove 86 via the pull rod 88, thus compressing the third spring 810. When the locking block 812 moves outward with the pull rod 88 and is removed from the locking groove 811, the pull rod 88 is rotated, causing the third slider 89 to rotate synchronously. Since the third slider 89 is slidably connected to the cavity 85 and the third groove 86, and the third groove 86 is located on the top and bottom inner walls of the cavity 85, the third slider 89 will drive the rotating shaft 84 to rotate synchronously with the pull rod 88 within the rotating groove 83, thereby driving the screw 82 to move. As the screw 82 rotates and is threadedly connected to the second connecting seat 7, the second connecting seat 7 will slide along the adjusting groove 81 as the screw 82 rotates, thereby adjusting the position of the second mounting ring 4. When the distance between the first mounting ring 3 and the second mounting ring 4 matches the patient's body shape, the first pull block 813 is released, the third spring 810 rebounds and drives the pull rod 88 to move inward through the third slider 89. When the locking block 812 moves inward with the pull rod 88 into the insertion slot 811, the pull rod 88 can be fixed at the current angle, thereby stopping the screw 82 from rotating and keeping the second mounting ring 4 in the current position. Then, the patient can be cleaned and dressed.

[0043] Example 3:

[0044] This embodiment is basically the same as the previous embodiment, except that the four outer corners of the base 1 are provided with fixing components 9 for fixing the base 1 to the workbench. The fixing components 9 include mounting base 91, air chamber 92, suction cup 93, piston 94, vertical rod 95, lifting groove 96, fixing groove 97, fixing block 98 and second pull block 99.

[0045] Furthermore, the mounting base 91 is fixedly connected to the outer sides of the four corners of the base 1, the air chamber 92 passes through the middle of the mounting base 91, the suction cup 93 is installed at the bottom of the mounting base 91 and is connected to the air chamber 92, the piston 94 is slidably connected to the air chamber 92 and is sized to match, the vertical rod 95 is movably connected to the air chamber 92 and its bottom is rotatably connected to the top of the piston 94, the lifting groove 96 is opened on both sides of the upper half of the air chamber 92, the fixing groove 97 is opened on one side of the top of the lifting groove 96 and is interconnected, the fixing block 98 is fixedly connected to both sides of the middle of the vertical rod 95 and is slidably connected to the lifting groove 96 and the fixing groove 97, and the second pull block 99 is fixedly connected to the top of the vertical rod 95.

[0046] Working principle: Before applying debridement dressing to the patient, first place the base 1 on the workbench and ensure the suction cup 93 is tightly attached to the workbench. Then, pull the second pull block 99 upwards, causing it to drive the piston 94 upwards along the air chamber 92 via the vertical rod 95. At this time, the air in the suction cup 93 is drawn into the air chamber 92, creating a negative pressure environment. During this process, the fixing block 98 slides upwards along the lifting groove 96 synchronously with the vertical rod 95. When the fixing block 98 slides to the top of the lifting groove 96, rotate the vertical rod 95 to drive the fixing block 98 to rotate synchronously. When the fixing block 98 rotates into the fixing groove 97... The vertical rod 95 and piston 94 can be fixed at the current height, thereby maintaining negative pressure inside the suction cup 93. Then, atmospheric pressure is used to fix the base 1 on the workbench. After that, the patient can be cleaned and dressed. After the cleaning and dressing work is completed, the vertical rod 95 is rotated in the opposite direction to make the fixing block 98 rotate from the fixing groove 97 to the lifting groove 96. Then, the second pull block 99 is pressed down to make the piston 94 slide down along the air chamber 92 through the vertical rod 95. At this time, the air in the air chamber 92 is sent into the suction cup 93. When the pressure inside the suction cup 93 is the same as the atmospheric pressure, the fixing of the base 1 can be released.

[0047] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
