Description

Technical Field

[0001] This invention belongs to the field of medical device technology, specifically referring to a burn wound care device. Background Technology

[0002] The core needs of burn wound care are to achieve uniform drug coverage, avoid secondary damage, and adapt to different limb shapes. However, the current main method is manual care, which has obvious defects. It is difficult for medical staff to control the force, which can easily cause scratching and pressure damage to the wound. In addition, the limited operating angle often leads to drug accumulation or omission, resulting in low efficiency and making it unsuitable for large-area or multi-patient care scenarios. Summary of the Invention

[0003] In order to overcome the shortcomings of the prior art, the present invention provides a burn wound care device that effectively solves the above problems.

[0004] The technical solution adopted by the present invention is as follows: The present invention proposes a burn wound care device, including a care component, a support component and a base. The care component and the support component are disposed on the base, and the support component is located in front of the care component. The care component includes a housing, a drive ring, a care ring and a double gear component. The housing slides on the base. The drive ring and the care ring are disposed inside the housing. The double gear component is disposed at the top inside the housing. The drive ring and the care ring are connected by the double gear component.

[0005] Furthermore, the outer side of the housing is provided with a drive rod groove, the drive ring is provided on the drive rod groove, the inner side of the housing is provided with a slider ring groove, the nursing ring is provided on the slider ring groove, and the bottom of the housing is symmetrically provided with sliding supports, the sliding supports sliding on the base.

[0006] Furthermore, the housing has a gear hole at its top, the double gear rotates on the gear hole, the sliding support has a transverse gear groove and a longitudinal lead screw groove, the lead screw groove passes through the gear groove, and the side wall of the lead screw groove has a spring groove.

[0007] Furthermore, the nursing component also includes a medication applicator, a lead screw and gear, and a lead screw and spring. The medication applicator is located on the nursing ring, the lead screw and gear are located in a gear groove, and the lead screw and spring are located in a spring groove.

[0008] Furthermore, the drive ring is provided with a drive rod, an external gear and an internal gear. The internal gear is located on the side wall of the external gear, the drive rod is located on the external gear, the drive rod slides in the drive rod groove, and the external gear meshes with the lead screw gear.

[0009] Preferably, medical staff only need to pull the drive rod back and forth to complete the linkage between the movement of the nursing component and the rotation of the medication application. When pulled counterclockwise, the external gear drives the lead screw gear to rotate, and the lead screw moves along the inclined surface of the inclined bottom groove, pushing the nursing component forward and simultaneously driving the nursing ring to rotate and apply medication, achieving the technical effect of applying medication while the nursing component moves. When reset clockwise, the lead screw moves outward along the inclined bottom groove, causing the lead screw gear to disengage from the external gear, preventing the nursing component from moving backward and avoiding repeated medication application. Resetting the nursing component only requires pushing the housing backward by hand, making the operation convenient.

[0010] Furthermore, the nursing ring is provided with a side gear, a positioning slider and a sealing ring. The positioning slider is located on the side wall of the side gear, and the sealing ring is located inside the positioning slider. The positioning slider slides on the slider ring groove, and the sealing ring is attached to the slider ring groove.

[0011] Preferably, when the drive ring rotates, it drives the double gear component through the internal gear, and then drives the transmission chain of the nursing ring through the double gear component, thus rotating the nursing ring. The ratio of the large gear to the small gear of the double gear component is 1:2. Combined with the design that the angle of the drive rod slide is greater than 180°, when the drive rod rotates in one direction, the nursing ring rotates more than 360°, which drives the medication applicator to fully cover the wound surface and avoid local omissions. The medication applicator is fixed to the nursing ring and rotates stably with the nursing ring. Compared with manual application, the force is more uniform and can avoid secondary damage to the wound surface caused by fluctuations in the force of manual operation (such as excessive scraping or pressing).

[0012] Furthermore, the positioning slider has an inner mounting hole, the top of the medicine-attaching component has a mounting rod, the mounting rod is located in the mounting hole, the double gear component has a large gear and a small gear, the small gear is located below the large gear, the large gear is meshed with the side gear, and the inner gear is meshed with the small gear.

[0013] Preferably, the medication application device is detachable and replaceable through a connection structure where the installation rod is inserted into the installation hole. The appropriate size of the medication application device can be selected according to the size and location of the wound, avoiding the application area being too large or too small, and making it more targeted.

[0014] Furthermore, the base is provided with a mounting seat, a slide, and a lead screw. The top of the mounting seat is provided with a second support groove. The side walls of the mounting seat and the slide are symmetrically provided with inclined bottom grooves. The two ends of the lead screw are spherical, and the two ends of the lead screw are respectively attached to the inner walls of the two inclined bottom grooves. The lead screw is located in the lead screw groove, and the lead screw and the lead screw gear are connected by threads. The lead screw spring is attached to the lead screw, and the sliding support slides on the slide.

[0015] Furthermore, the support assembly includes a sliding plate, a support base, and an adjusting screw. The sliding plate slides on the carriage, the support bases are symmetrically arranged on the sliding plate, and another support base is symmetrically arranged on the mounting base. The adjusting screw passes through the sliding plate, and another adjusting screw passes through the second sliding groove of the support base. The adjusting screw is located at the bottom of the support base, and the threads on both sides of the adjusting screw are in opposite directions.

[0016] Furthermore, the top of the sliding plate is provided with a support seat groove one, the arc surface of the support seat is provided with an elastic pad, the bottom of the support seat is provided with a slide rail, the slide rail slides in the support seat groove one and the support seat groove two, the slide rail is provided with a threaded hole, the threaded hole is connected to the adjusting screw by a thread, one side of the slide rail is provided with an insert plate, the other side of the slide rail is provided with a slot, and the insert plate is located in the slot.

[0017] Preferably, in the support assembly, the sliding plate can slide along the carriage to adjust the distance from the placement seat. At the same time, rotating the adjusting screw can drive the symmetrical support seats to open and close along the sliding groove, adapting to limbs of different thicknesses, such as arms and calves. The cushioning effect of the elastic pad can reduce the hard contact between the limb and the support seat. For sensitive limbs after burns, it can avoid compressing the normal tissue around the burn wound, thereby avoiding affecting blood circulation. The nursing component slides smoothly along the carriage, and the medication application component rotates gently with the nursing ring without violent friction or impact, reducing the patient's pain.

[0018] The beneficial effects achieved by the present invention using the above structure are as follows: 1. Medical staff only need to pull the drive rod back and forth to complete the linkage between the movement of the nursing component and the rotation of the medication application. When pulled counterclockwise, the external gear drives the lead screw gear to rotate, and the lead screw moves along the inclined surface of the inclined bottom groove, pushing the nursing component forward. At the same time, it drives the nursing ring to rotate and apply medication, achieving the technical effect of applying medication while the nursing component moves. When reset clockwise, the lead screw moves outward along the inclined bottom groove, causing the lead screw gear to disengage from the external gear, and the nursing component does not move backward, avoiding repeated medication application. Resetting the nursing component only requires pushing the housing backward by hand, which is convenient to operate.

[0019] 2. When the drive ring rotates, it drives the double gear component through the internal gear, and then drives the transmission chain of the nursing ring through the double gear component, causing the nursing ring to rotate. The ratio of the large gear to the small gear of the double gear component is 1:2. Combined with the design of the drive rod slide groove angle greater than 180°, when the drive rod rotates in one direction, the nursing ring rotates more than 360°, causing the medication applicator to fully cover the wound surface, avoiding local omissions. The medication applicator is fixed to the nursing ring and rotates stably with the nursing ring. Compared with manual application, the pressure is more uniform, which can avoid secondary damage to the wound surface caused by fluctuations in the pressure of manual operation (such as scraping or excessive pressure).

[0020] 3. The medication application device is detachable and replaceable through the connection structure of the installation rod inserted into the installation hole. The appropriate size medication application device can be selected according to the size and location of the wound, avoiding the application area being too large or too small, and making it more targeted.

[0021] 4. In the support assembly, the sliding plate can slide along the carriage to adjust the distance from the placement seat. At the same time, rotating the adjusting screw can drive the symmetrical support seats to open and close along the sliding groove, adapting to limbs of different thicknesses, such as arms and calves. The cushioning effect of the elastic pad can reduce the hard contact between the limb and the support seat. For sensitive limbs after burns, it can avoid compressing the normal tissue around the burn wound, thereby avoiding affecting blood circulation. The nursing component slides smoothly along the carriage, and the medication application component rotates gently with the nursing ring without violent friction or impact, reducing the patient's pain.

[0027] like Figures 1-13 As shown, the present invention proposes a burn wound care device, including a care component 1, a support component 2, and a base 3. The care component 1 and the support component 2 are disposed on the base 3, and the support component 2 is located in front of the care component 1. The care component 1 includes a housing 11, a drive ring 12, a care ring 13, and a double gear component 15. The housing 11 slides on the base 3. The drive ring 12 and the care ring 13 are disposed inside the housing 11. The double gear component 15 is disposed at the top inside the housing 11. The drive ring 12 and the care ring 13 are connected by the double gear component 15.

[0028] The outer side of the housing 11 is provided with a drive rod groove 111, and a drive ring 12 is provided on the drive rod groove 111. The inner side of the housing 11 is provided with a slider ring groove 112, and a nursing ring 13 is provided on the slider ring groove 112. The bottom of the housing 11 is symmetrically provided with sliding supports 113, which slide on the base 3.

[0029] The housing 11 has a gear hole 115 at the top inside, and the double gear component 15 rotates on the gear hole 115. The sliding support 113 has a transverse gear groove 114 and a longitudinal lead screw groove 116. The lead screw groove 116 passes through the gear groove 114, and the side wall of the lead screw groove 116 has a spring groove 117.

[0030] The nursing component 1 also includes a medication feeder 14, a lead screw and gear 16, and a lead screw and spring 17.

[0031] The drive ring 12 is provided with a drive rod 121, an external gear 122 and an internal gear 123. The internal gear 123 is located on the side wall of the external gear 122. The drive rod 121 is located on the external gear 122. The drive rod 121 slides in the drive rod groove 111. The external gear 122 is meshed with the lead screw gear 16.

[0032] The nursing ring 13 is provided with a side gear 131, a positioning slider 132 and a sealing ring 133. The positioning slider 132 is located on the side wall of the side gear 131, and the sealing ring 133 is located inside the positioning slider 132. The positioning slider 132 slides on the slider ring groove 112, and the sealing ring 133 fits against the slider ring groove 112.

[0033] The positioning slider 132 has a mounting hole 1321 on its inner side. The top of the medicine loading part 14 has a mounting rod 141, which is located in the mounting hole 1321. The double gear part 15 has a large gear 151 and a small gear 152. The small gear 152 is located below the large gear 151. The large gear 151 is meshed with the side gear 131, and the inner gear 123 is meshed with the small gear 152.

[0034] The base 3 is provided with a mounting seat 31, a slide 32 and a lead screw 33. The top of the mounting seat 31 is provided with a support groove 311. The side walls of the mounting seat 31 and the slide 32 are symmetrically provided with inclined bottom grooves 312. The two ends of the lead screw 33 are spherical, and the two ends of the lead screw 33 are respectively attached to the inner walls of the inclined bottom grooves 312 on both sides. The lead screw 33 is located in the lead screw groove 116, and the lead screw 33 is connected to the lead screw gear 16 by threads. The lead screw spring 17 is attached to the lead screw 33. The sliding support 113 slides on the slide 32.

[0035] The support assembly 2 includes a sliding plate 21, a support seat 22, and an adjusting screw 23. The sliding plate 21 slides on the carriage 32. The support seats 22 are symmetrically arranged on the sliding plate 21, and another support seat 22 is symmetrically arranged on the mounting seat 31. The adjusting screw 23 passes through the sliding plate 21, and another adjusting screw 23 passes through the second groove 311 of the support seat. The adjusting screw 23 is located at the bottom of the support seat 22, and the threads on both sides of the adjusting screw 23 are in opposite directions.

[0036] The top of the sliding plate 21 is provided with a support groove 211, the arc surface of the support 22 is provided with an elastic pad 221, the bottom of the support 22 is provided with a slide rail 222, the slide rail 222 slides in the support groove 211 and the support groove 311, the slide rail 222 is provided with a threaded hole 2221, the threaded hole 2221 is connected to the adjusting screw 23 by a thread, one side of the slide rail 222 is provided with an insert plate 223, the other side of the slide rail 222 is provided with a slot 224, and the insert plate 223 is located in the slot 224.

[0037] In practical use, the distance between the support assembly 2 and the placement seat 31 is adjusted by sliding the sliding plate 21 in the sliding support assembly 2 according to the thickness of the patient's limb and the size of the burn wound. The distance between the two support seats 22 is adjusted by rotating the adjusting screw 23 so that the patient can place the limb on the support seat 22. The elastic pad 221 has an elastic cushioning effect, which fits the curve of the limb better, reduces pressure points, and maintains smooth blood circulation. The patient passes the limb through the nursing assembly 1 and places it on the support seat 22.

[0038] The doctor takes out the appropriately sized medication applicator 14, dips it in the required medication, and installs it on the nursing ring 13. The doctor then pulls the drive rod 121 back and forth with their finger, causing the drive ring 12 to rotate. This, in turn, causes the external gear 122 to drive the lead screw gear 16 to rotate. The lead screw gear 16 then moves along the lead screw 33. Because forces are reciprocal, as the lead screw gear 16 rotates and moves forward, it pushes the lead screw 33 backward. Since the inner wall of the inclined groove 312 is designed with an incline, when the lead screw 33 moves backward, it moves deeper into the inclined groove 312 on the mounting base 31. This causes the lead screw 33 to drive the lead screw gear 16 closer to the drive ring 12, ensuring that the lead screw gear 16 and the external gear 122 are always in contact. In the meshing connection, as the lead screw gear 16 rotates and moves backward, it pushes the lead screw 33 to move forward. The inner wall of the inclined bottom groove 312 on the slide 32 tilts outward, that is, the lead screw 33 moves away from the drive ring 12, causing the lead screw 33 to drive the lead screw gear 16 away from the external gear 122, so that the external gear 122 cannot mesh with the lead screw gear 16. At this time, the rotation of the drive rod 121 will not affect the movement of the care component 1. That is, when the drive rod 121 is rotated counterclockwise, the care component 1 can be pushed forward. When the drive ring 12 is reset clockwise, the care component 1 will not move backward. When the care component 1 needs to be reset, it is only necessary to push the housing 11 backward.

[0039] During the rotation of the drive ring 12, it also drives the double gear component 15 to rotate, which in turn drives the nursing ring 13 to rotate. The transmission ratio of the large gear 151 and the small gear 152 on the double gear component 15 is 1:2, and the angle of the drive rod slide groove 111 is greater than 180°. This allows the drive rod 121 to drive the nursing ring 13 to rotate more than 360° during its unidirectional rotation within the drive rod slide groove 111. This enables the medication application component 14 to be applied to the patient's burn wound from all directions, thus cleaning and applying medication to the burn wound.
