Description

Technical Field

[0001] This utility model relates to the field of nursing pillow technology, specifically a clinical lateral decubitus ear pressure ulcer protection pillow. Background Technology

[0002] In clinical practice, patients requiring prolonged bed rest, such as those recovering from surgery, the frail elderly, or those with nerve palsy, often need to maintain a lateral decubitus position to meet their treatment needs. However, in this position, the lower auricle is easily trapped between the head and the pillow, causing local pressure that exceeds the tolerance threshold of the skin's capillaries. This leads to vascular occlusion, tissue ischemia and hypoxia, and consequently, pressure sores on the auricle. These pressure sores heal slowly due to insufficient blood supply to the auricle and are prone to secondary infections, further exacerbating patient suffering and the medical burden. To address this issue, existing clinical lateral decubitus ear pressure-reducing pillows utilize pre-designed pressure-reducing grooves or hollow areas that conform to the physiological shape of the auricle, combined with high-density memory foam and other materials to disperse head pressure and help maintain blood supply to the auricle to reduce the risk of pressure sores. However, several technical shortcomings remain in practical application. Firstly, individual adaptability is poor. Most are "one-size-fits-all" designs, and the size and depth of the pressure-reducing grooves cannot match the differences among patients. When used by children, the auricle is prone to shifting; in obese patients, the auricle is easily squeezed to the edge of the groove; and in thin patients, the edge of the auricle still touches the pillow surface, limiting their applicability. Secondly, when patients turn over, their heads are easily misaligned with the pillow, and their auricles are dislodged from the decompression zone. Medical staff need to repeatedly adjust the alignment, which increases the nursing burden and may delay protective measures.

[0003] Therefore, this utility model provides a pressure relief pillow for the auricle in clinical lateral decubitus position to prevent pressure sores. Utility Model Content

[0004] This invention provides a pressure-reducing pillow for the auricle in clinical lateral decubitus position to prevent pressure sores, aiming to solve the problems mentioned in the background art.

[0005] To solve the above problems, this utility model is implemented through the following technical solution: a clinical lateral decubitus ear pressure ulcer protection pillow, including a nursing pillow, the top of which is provided with two receiving slots, the nursing pillow having several replacement blocks, and the bottom of the nursing pillow being provided with a movable mechanism, wherein each of the several replacement blocks is provided with a clearance groove, the size of the several clearance grooves increasing sequentially, the replacement block being engaged with the inner wall of the receiving slot, and the clearance groove being located at an eccentric position on the corresponding replacement block, the movable mechanism including an upper plate and a lower plate, the nursing pillow being detachably connected to the top of the upper plate, and the upper plate being slidably connected to the top of the lower plate.

[0006] Preferably, each of the two receiving slots is equipped with a first hook and loop fastener, and the bottom of each of the several replacement patches is equipped with a first hook and loop fastener velvet surface that contacts the first hook and loop fastener.

[0007] Preferably, the bottom of the upper plate is provided with a plurality of sliders, the top of the lower plate is provided with a plurality of grooves, the sliders are slidably connected to the inner wall of the corresponding groove, the inner wall of the groove is provided with a guide rod, and the sliders are slidably connected to the outer side of the corresponding guide rod.

[0008] Preferably, the top of the upper plate is provided with a plurality of second hook and loop fasteners, and the bottom of the nursing pillow is provided with a plurality of second hook and loop fasteners that mate with the second hook and loop fasteners.

[0009] Preferably, both the upper plate and the lower plate have through holes, wherein a rotating plate is rotatably connected to the inner wall of the upper through hole, the rotating plate is engaged with the inner wall of the lower through hole, and a knob for controlling the rotating plate is rotatably connected to one side of the upper plate.

[0010] Beneficial effects

[0011] Compared with the prior art, the present invention has the following advantages:

[0012] This invention allows medical staff to select a replacement patch with a correspondingly sized relief groove based on the size of the patient's auricle, and insert it into the receiving groove at a suitable angle. When the patient is lying on their side, the auricle can be placed in the relief groove. The structure of the replacement patch and the nursing pillow helps to distribute the pressure on the head, preventing the auricle from being directly pressured. This avoids the local pressure from exceeding the tolerance threshold of the skin capillaries, reducing the risk of vascular occlusion, tissue ischemia and hypoxia, and lowering the risk of pressure sores on the auricle.

[0013] When the patient turns over, the nursing pillow and upper board slide on the lower board. This allows the positioning groove to quickly and accurately align with the auricle when the patient turns to the side again, eliminating the need for medical staff to repeatedly adjust the position of the nursing pillow and the patient's head. This reduces the nursing burden and avoids delays in protection due to untimely adjustments or inaccurate alignment. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-5 A clinical lateral decubitus ear pressure ulcer protection pillow includes a nursing pillow 1, with two receiving slots 11 at the top of the nursing pillow 1, several replacement blocks 2, and a movable mechanism 3 at the bottom of the nursing pillow 1.

[0022] Among them, several replacement blocks 2 are provided with relief grooves 21, and the size of several relief grooves 21 increases sequentially. The replacement blocks 2 are engaged and connected to the inner wall of the receiving groove 11, and the relief grooves 21 are located at the eccentric position on the corresponding replacement blocks 2.

[0023] It should be noted that the clearance groove 21 described in this embodiment can be inserted into the receiving groove 11 at different angles.

[0024] The active mechanism 3 includes an upper plate 31 and a lower plate 32. The nursing pillow 1 is detachably connected to the top of the upper plate 31, and the upper plate 31 is slidably connected to the top of the lower plate 32.

[0025] Specifically, the nursing pillow 1 has two receiving slots 11 at its top and is equipped with several replacement blocks 2. Each replacement block 2 has a relief groove 21, and the size of the relief grooves 21 increases sequentially. The replacement blocks 2 can be snapped into the inner wall of the receiving slot 11, and the relief groove 21 is located at an off-center position on the corresponding replacement block 2, allowing it to be inserted into the receiving slot 11 from different angles. In actual use, medical staff can select a replacement block 2 with a relief groove 21 of the corresponding size according to the size of the patient's auricle, and snap it into the receiving slot 11 at a suitable angle, so that when the patient is lying on their side, the auricle can be placed in the relief groove 21. The structure of the replacement blocks 2 and the nursing pillow 1 helps to distribute the pressure on the head and prevent the auricle from being directly pressured. This avoids local pressure exceeding the tolerance threshold of skin capillaries, reducing vascular occlusion, tissue ischemia and hypoxia, and lowering the risk of pressure sores on the auricle. In addition, the bottom of the nursing pillow 1 is equipped with a movable mechanism 3, which includes an upper plate 31 and a lower plate 32. The nursing pillow 1 is detachably connected to the top of the upper plate 31, and the upper plate 31 is slidably connected to the top of the lower plate 32. When the patient turns over, the nursing pillow 1 and the upper plate 31 will slide on the lower plate 32. This allows the positioning groove 21 to quickly and accurately align with the auricle when the patient turns to the side again, eliminating the need for medical staff to repeatedly adjust the position of the nursing pillow 1 and the patient's head, reducing the nursing burden, and avoiding delays in protection due to untimely adjustments or inaccurate alignment.

[0026] In one embodiment of this utility model, such as Figures 1-5 As shown, each of the two receiving slots 11 is equipped with a first hook and loop hook surface 12, and the bottom of each of the several replacement patches 2 is equipped with a first hook and loop fleece surface 22 that mates with the first hook and loop hook surface 12.

[0027] Specifically, a first Velcro hook surface 12 is installed in each of the two receiving slots 11, and a number of replacement patches 2 have a first Velcro velvet surface 22 attached to the bottom of the first Velcro hook surface 12. In use, a replacement patch 2 with a correspondingly sized relief groove 21 can be selected according to the size of the patient's auricle. Through the adhesive action of the first Velcro hook surface 12 and the first Velcro velvet surface 22, the replacement patch 2 is securely installed in the receiving slot 11, so that the auricle can be placed in the relief groove 21 when the patient is lying on their side. The structure of the replacement patch 2 and the nursing pillow 1 helps to distribute the pressure on the head and avoid direct pressure on the auricle.

[0028] In one embodiment of this utility model, such as Figures 1-5 As shown, several sliders 311 are installed at the bottom of the upper plate 31, and several grooves 321 are opened at the top of the lower plate 32. The sliders 311 are slidably connected to the inner wall of the corresponding groove 321. Guide rods 322 are installed on the inner wall of the groove 321, and the sliders 311 are slidably connected to the outer side of the corresponding guide rods 322.

[0029] Specifically, when the patient turns over, causing the nursing pillow 1 and the upper plate 31 to move, the slider 311 can slide along the slide groove 321. The guide rod 322 guides the sliding of the slider 311, ensuring the stability and smoothness of the upper plate 31 sliding on the lower plate 32. This makes it easier for the positioning groove 21 to quickly and accurately align with the auricle when the patient turns to the side again.

[0030] In one embodiment of this utility model, such as Figures 1-5 As shown, the top of the upper plate 31 is equipped with several second hook and loop hook surfaces 312, and the bottom of the nursing pillow 1 is equipped with several second hook and loop fleece surfaces 13 that are connected to the second hook and loop hook surfaces 312.

[0031] Specifically, several second hook-and-loop fasteners 312 are installed at the top of the upper plate 31, and several second hook-and-loop fasteners 13 that mate with the hook-and-loop fasteners 312 are installed at the bottom of the nursing pillow 1. Through the adhesive cooperation between the hook-and-loop fasteners 312 and the second hook-and-loop fasteners 13, the nursing pillow 1 can be conveniently and securely installed on the upper plate 31, and can be used in combination or alone.

[0032] In one embodiment of this utility model, such as Figures 1-5 As shown, both the upper plate 31 and the lower plate 32 have through holes 33. The inner wall of the upper through hole 33 is rotatably connected to a rotating plate 34, which is engaged with the inner wall of the lower through hole 33. A knob 341 for controlling the rotating plate 34 is rotatably connected to one side of the upper plate 31.

[0033] Specifically, when the patient does not need to turn over and remains in a stable lateral position, the knob 341 can be turned to rotate the rotating plate 34 and engage it in the through hole 33 of the lower plate 32. Through the engagement of the rotating plate 34 with the through hole 33 of the upper and lower plates, the sliding of the upper plate 31 relative to the lower plate 32 is restricted, ensuring the stability of the nursing pillow 1 and preventing the nursing pillow 1 from shifting or the positioning groove 21 from dislodging from the auricle due to slight movements of the patient. When the patient needs to turn over, the knob 341 is turned in the opposite direction to rotate the rotating plate 34 out of the through hole 33 of the upper plate 31, releasing its engagement restriction with the through hole 33 of the lower plate 32. At this time, the upper plate 31 can drive the nursing pillow 1 to slide smoothly on the lower plate 32 with the patient's turning over, making it easier for the positioning groove 21 to be accurately aligned with the auricle when the patient turns over again.

[0034] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0035] Working principle: In use, first select a replacement patch 2 with a correspondingly sized relief groove 21 according to the size of the patient's auricle. Then, attach the replacement patch 2 to the first Velcro hook surface 12 inside the receiving groove 11 and the first Velcro velvet surface 22 at the bottom of the replacement patch 2. Insert the replacement patch 2 into the receiving groove 11 at a suitable angle. When the patient is in a side-lying position, the auricle is placed in the relief groove 21. The nursing pillow 1 and the replacement patch 2 distribute the pressure on the head, preventing direct pressure on the auricle. The nursing pillow 1 is securely installed on the upper plate 31 by attaching the second Velcro velvet surface 13 at the bottom to the second Velcro hook surface 312 at the top of the upper plate 31. When there is no need to turn over, turn knob 341 to make rotating plate 34 engage with through hole 33 of upper plate 31 and lower plate 32, restricting the sliding of upper plate 31; when turning over is required, turn knob 341 in the opposite direction to release the restriction, and the patient moves nursing pillow 1 and upper plate 31. The bottom slider 311 of upper plate 31 slides along slide groove 321 and guide rod 322 of lower plate 32 to ensure stable and smooth sliding, so that positioning groove 21 can be accurately aligned with auricle again.
