Description

Technical Field

[0001] This invention relates to the field of medical device technology, and in particular to a wrap-around turning bed for burn treatment. Background Technology

[0002] A wrap-around turning bed is a device used to protect and assist burn patients in turning over. During the treatment of burn patients, the patient needs to be fixed between two bed boards to wrap them up for protection. When the patient needs to turn over, the two bed boards can be rotated to assist the patient. However, placing the patient directly on the bed will cause the patient's burn area to come into direct contact with the sheet or mattress. This will cause the patient's burn area to be squeezed by the bed board, and may even cause relative movement between the burn area and the bed board, resulting in secondary trauma to the patient's burn area and thus affecting the patient's healing process. Summary of the Invention

[0003] To overcome the drawback of secondary trauma to the burn site caused by the pressure of the bed board on the burn area, this invention provides a wrapping turning bed for burn treatment.

[0004] The technical solution of the present invention is: a burn medical wrapping turning bed, comprising a bed frame, two symmetrically distributed rotating frames rotatably connected to the bed frame, a locking device provided between the rotating frames and the bed frame, two symmetrically distributed bed bodies slidably connected together by the two rotating frames, a locking device installed on the rotating frames for locking the two bed bodies, a plurality of spaced sliding frames slidably connected to opposite sides of the two bed bodies, a plurality of flexible pads fixedly connected to the sliding frames, the sliding frames being used to drive all the flexible pads thereon to slide, thereby adjusting the position of the flexible pads, so that the flexible pads support the patient while avoiding the patient's burn area.

[0005] Preferably, there is a gap between two adjacent flexible pads to ensure airflow between them.

[0006] Preferably, the flexible pad has a cavity for filling with liquid.

[0007] Preferably, the sliding frame is provided with a liquid inlet blind hole and a liquid return blind hole, and the cavity of the flexible pad is simultaneously connected to the adjacent liquid inlet blind hole and the adjacent liquid return blind hole. Both the liquid inlet blind hole and the liquid return blind hole are connected to an external liquid supply system.

[0008] Preferably, the liquid inlet blind hole and the liquid return blind hole are located on both sides of the cavity corresponding to the flexible pad, and the liquid inlet blind hole and the liquid return blind hole are centrally symmetrically distributed.

[0009] Preferably, the sliding frame is provided with symmetrically distributed rotating shafts, and the rotating shafts are provided with a first flexible part and a second flexible part, which are used to support and compress all the flexible pads on adjacent sliding frames.

[0010] Preferably, the rotating shaft is rotatably connected to symmetrically distributed connecting frames, and the connecting frames are rotatably connected to threaded rods that are rotatably connected to the adjacent sliding frames.

[0011] Preferably, one of the bed bodies is threaded with a plurality of rectangularly distributed support rods, which are used to support the other bed body to control the distance between the two bed bodies.

[0012] Preferably, the bed body below is slidably connected with several sets of sliding plates, each set of sliding plates having two symmetrically distributed sliding plates, the sliding plates in the same set being located between two adjacent sliding frames, and flexible blocks being fixedly connected to the opposite sides of the two sliding plates in the same set.

[0013] Preferably, the two sliding plates in the same group are threadedly connected to a lead screw that is rotatably connected to the bed below.

[0014] The advantages and positive effects of this invention compared with the prior art are: 1. This invention adjusts the position of all sliding frames and all flexible pads so that the flexible pads avoid the patient's burn area to adapt to patients with different burn areas, and uses the flexible pads to support the patient's burn area, and places the patient's burn area between two adjacent sliding frames, reducing the probability of squeezing and friction between the patient's burn area and the bed, thereby reducing the probability of secondary damage to the patient's burn area and improving the patient's comfort.

[0015] 2. By rotating the four support rods, the height of the upper bed can be adjusted, thereby changing the distance between the two beds to accommodate patients of different body types and improve the applicability of this device. When disassembling or assembling the upper bed, the four support rods support the upper bed to reduce the probability of the patient being pressured due to the shaking of the upper bed, thereby improving the patient's comfort when turning over.

[0016] 3. By rotating the lead screw, the distance between the two sliding plates is adjusted so that the two flexible blocks can fit patients of different body shapes, thereby improving the adaptability of this device. When it is necessary to turn the patient over, the sliding plates and flexible blocks support the patient's sides, reducing the probability of the patient sliding on the bed due to gravity when turning over, thereby reducing the probability of friction between the patient's burn area and the bed, thus reducing the probability of secondary trauma to the burn area when the patient is turned over, and thus improving the comfort of the patient when turning over.

Detailed Implementation

[0025] The following description is only a preferred embodiment of the present invention and does not limit the scope of protection of the present invention.

[0026] Example 1

[0027] Existing turning beds wrap the patient, which causes the patient's burn area to be compressed by the bed, and may even cause relative movement between the burn area and the bed board, resulting in secondary trauma to the patient's burn area and affecting the patient's comfort during the healing process.

[0028] A type of wrap-around turning bed for burn treatment, such as Figures 1-5As shown, the bed includes a bed frame 1, with two symmetrically distributed rotating frames 2 rotatably connected to the bed frame 1. A locking mechanism is provided between the rotating frames 2 and the bed frame 1. This locking mechanism is an existing structure and is not shown in the figure. Initially, the locking mechanism locks the rotating frames 2 to prevent them from rotating. When rotation of the rotating frames 2 is needed, the locking mechanism is unlocked, allowing the rotating frames 2 to rotate. The two rotating frames 2 are slidably connected to two symmetrically distributed bed bodies 3. The bed bodies 3 consist of a rigid bed frame and a flexible mattress in the middle. The rotating frames 2 are equipped with locking devices, which can be nuts. The two bed bodies 3 are... After the patient is sandwiched between the two bed frames 3, the bed frame 3 is locked in place by locking devices. Several sliding frames 4 are slidably connected to opposite sides of both bed frames 3, and several flexible pads 5 are fixed to each sliding frame 4. The sliding frames 4 are used to slide all the flexible pads 5 on them to adjust their positions, thus supporting the patient while avoiding the patient's burn area. When this structure is needed, a sheet is laid on the lower bed frame 3 to cover all the sliding frames 4 and all the flexible pads 5. The flexible pads 5 are used to support the patient's unburned areas, reducing the pressure on the patient's burn area when in contact with the sheet. Pressure is applied to reduce the probability of secondary injury to the patient's burn site due to pressure. Gaps exist between adjacent flexible pads 5 to ensure airflow between them, thereby increasing ventilation among all flexible pads 5 and improving patient comfort. Each flexible pad 5 has a cavity for filling with liquid. The sliding frame 4 has a liquid inlet blind hole 401 and a liquid return blind hole 402. The cavity of the flexible pad 5 communicates with both adjacent liquid inlet blind holes 401 and 402. Both liquid inlet blind holes 401 and 402 are connected to an external liquid supply system, which is used to deliver liquid... Liquid is injected through the inlet blind hole 401 to allow liquid to enter the cavities of all flexible pads 5 on the sliding frame 4. Subsequently, the liquid in the cavities flows back to the external liquid supply system through the return blind hole 402. The liquid flowing in the cavities physically cools the burn patient to reduce the patient's pain. Furthermore, the inlet blind hole 401 and the return blind hole 402 are located on the left and right sides of the corresponding flexible pad 5 cavities, respectively. The inlet blind hole 401 and the return blind hole 402 are centrally symmetrically distributed, ensuring that all paths through which the liquid flows are of the same length. This guarantees the uniformity of temperature of the sliding frame 4 and all flexible pads 5, thereby improving the patient's comfort.

[0029] The specific working principle is as follows:

[0030] Before using this device to cover the patient, the position of all the flexible pads 5 on the sliding frame 4 is adjusted to change the position of the flexible pads 5 supporting the patient, so that the flexible pads 5 avoid the patient's burn area and improve the patient's comfort at the burn area.

[0031] When the operator needs to use this device to wrap a burn patient, the operator unlocks the locking mechanism of bed 3, moves the upper bed 3 upwards, removes the upper bed 3, disinfects the device, then places the patient on the lower bed 3, and then installs the upper bed 3. After the upper bed 3 wraps the patient, the locking mechanism of bed 3 is reset and installed, wrapping the patient between the upper and lower bed 3, so that the unburned area of ​​the patient is in contact with the flexible pad 5. The flexible pad 5 supports the patient's burned area and places the patient's burned area between two adjacent sliding frames 4, reducing the probability of compression and friction between the patient's burned area and bed 3, thereby reducing the probability of secondary injury to the patient's burned area and improving patient comfort.

[0032] When it is necessary to turn the patient over, the operator rotates the rotating frame 2, causing the two bed bodies 3 to rotate the patient 180°. After the patient has finished turning over, the locking mechanism of the rotating frame 2 is locked, the locking mechanism of the bed body 3 is unlocked, and the upper bed body 3 is removed. After the patient recovers, the patient is lifted up from the lower bed body 3, the upper bed body 3 is reset, and the device is disinfected for the next use.

[0033] Example 2

[0034] Based on Example 1, such as Figure 3 , Figure 4 and Figure 6 As shown, the sliding frame 4 is provided with symmetrically distributed rotating shafts 6. The rotating shafts 6 are provided with a first flexible part 7 and a second flexible part 8. The first flexible part 7 and the second flexible part 8 are used to support and compress all the flexible pads 5 on the adjacent sliding frames 4. The hardness of the first flexible part 7 is greater than that of the second flexible part 8. The rotating shafts 6 are rotatably connected to the connecting frames 9 which are symmetrically distributed front and back. The contact surfaces between the rotating shafts 6 and the adjacent connecting frames 9 are rough surfaces to prevent the rotating shafts 6 from rotating on their own. The connecting frames 9 are rotatably connected to the threaded rods 10 which are rotatably connected to the adjacent sliding frames 4. By rotating the two symmetrically distributed threaded rods 10, the connecting frames 9 drive the rotating shafts 6 to move in the vertical direction to adjust the height of the rotating shafts 6. The support height of the first flexible part 7 or the second flexible part 8 on the rotating shafts 6 changes, thereby changing the support force of the flexible pads 5 on the patient. By rotating the rotating shafts 6, the orientation of the first flexible part 7 and the second flexible part 8 can be adjusted to change the support force of the flexible pads 5 on the patient, so as to adapt to the support force required by different patients and different positions of their bodies, thereby improving the comfort of burn patients.

[0035] Example 3

[0036] Existing wrap-around turning beds, after wrapping the patient, have gaps between the guide rails and the bed frame because the two bed frames are connected by two guide posts at the head and foot of the bed, and the guide posts have threaded grooves. Therefore, if the upper bed board slides unevenly on the two guide posts or deflects during the disassembly of the turning bed board, it may cause the bed board to press on the patient's burn area, resulting in secondary trauma to the patient and affecting the patient's comfort.

[0037] Based on Example 2, such as Figure 2 and Figure 7 As shown, the lower bed 3 is threaded with several rectangularly distributed support rods 11. When the upper bed 3 is disassembled or assembled, the support rods 11 support the upper bed 3 to reduce the probability of the patient being pressured due to the shaking of the upper bed 3. By rotating the four support rods 11, the height of the upper bed 3 can be adjusted, thereby controlling the distance between the two bed 3s to accommodate patients of different body types and improve the applicability of this device.

[0038] Example 4

[0039] Existing swaddle-type turning beds use bandages to secure the patient and the bed. However, when the bandages are wrapped around the bed, gaps are created between the bandages and the patient, preventing the patient from being properly secured to the bed. Once the bed is turned over, the patient will slide relative to the bed, resulting in friction and affecting the patient's comfort when turning over.

[0040] Based on Example 3, such as Figure 2 and Figure 7As shown, the lower bed 3 is slidably connected to several sets of sliding plates 12. Each set of sliding plates 12 has two plates symmetrically distributed front and back. The sliding plates 12 in the same set are located between two adjacent sliding frames 4. Flexible blocks 13 are fixed to the opposite sides of the two sliding plates 12 in the same set. The flexible blocks 13 are used to conform to the patient's body to reduce the pressure on the patient's body, thereby reducing the probability of secondary trauma to the patient's burn site. When it is necessary to turn the patient, the two rotating frames 2 drive the two bed 3 to turn. The sliding plates 12 and flexible blocks 13 support the patient's sides, reducing the probability of the patient sliding on the bed 3 due to gravity when turning, thereby reducing the probability of friction between the patient's burn site and the bed 3. To reduce the probability of secondary trauma to the burn site when the patient is turned over, thereby improving the patient's comfort during the turning process, the two sliding plates 12 in the same group are threadedly connected to a lead screw 14 that is rotatably connected to the bed body 3 below. The lead screw 14 is provided with two threaded protrusions, which are used to connect the two adjacent sliding plates 12 respectively. The threaded part of the sliding plate 12 that connects to the lead screw 14 is a threaded groove. The two threaded protrusions on the lead screw 14 are symmetrically distributed. By rotating the lead screw 14, the two sliding plates 12 can move in opposite directions and in opposite directions to adjust the distance between the two sliding plates 12, so that the two flexible blocks 13 can fit patients of different body types, thereby improving the adaptability of this device.
