[0002] Nursing pads are mostly hygiene products used by hospital patients, mainly for hospital surgery, postpartum care, infant care, paralyzed patients with urinary and fecal incontinence, women during menstruation, and patients with limited mobility.

[0003] However, existing partitioned inflatable nursing pads cannot automatically adjust the inflation saturation of the partitions according to the user's different postures. This can easily lead to insufficient lumbar support when the user is lying flat, resulting in lumbar disc herniation, or the pressure area decreases and the pressure increases when the user is lying on their side. The air volume of the pad does not adjust accordingly, which increases the probability of pressure sores. Utility Model Content

Detailed Implementation

[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 Figures 1-5 This utility model provides an embodiment of a partitioned inflatable pressure ulcer prevention pad, comprising two first air cushions 3, with two diversion pipes 2 connected to the side walls of the two first air cushions 3, and a main pipe 1 provided at one end of each of the two diversion pipes 2. Two second air cushions 4 are fixedly disposed between the two first air cushions 3, and two third air cushions 5 are fixedly connected between the two first air cushions 3. Each of the two third air cushions 5 is provided with a judgment mechanism. Two connecting pipes 10 are fixedly disposed at both ends of each of the two third air cushions 5, connecting to the corresponding first air cushion 3. The judgment mechanism is provided with two first switching mechanisms 6 and a second switching mechanism 7. First, the air pump is connected to the main pipe 1 for inflation. Inflation is stopped when the air is 80% full, and the main pipe 1 is plugged. When the user lies flat on the air cushion, the two third air cushions 5 are distributed. Due to the larger pressure area compared to the smaller pressure area of ​​the head and feet, the pressure is correspondingly greater. At this time, the judgment mechanism maintains the initial state, the first switching mechanism 6 closes and the second switching mechanism 7 opens, allowing the gas inside the first air cushion 3, where the pressure on the head and feet is greater, to enter the third air cushion 5 through the second switching mechanism 7. This reduces the inflation volume of the first air cushion 3 at the head and feet, making it softer and preventing pressure sores and discomfort, while increasing the inflation volume of the third air cushion 5 at the waist, making it firmer and increasing the user's lumbar support, thus preventing lumbar disc herniation. When the user lies on their side, the pressure area of ​​the torso is greatly reduced, causing the first switching mechanism 6 to open and the second switching mechanism 7 to close, allowing the gas in the third air cushion 5 to enter the first air cushion 3 through the first switching mechanism 6, reducing the pressure when sleeping on one's side.

[0022] Specifically, the two judgment mechanisms include two judgment plates with inverted T-shapes and T-slots; 8 and four judgment springs 9. The two judgment plates with inverted T-shapes and T-slots; 8 are respectively fixedly installed at the bottom and top of the third air cushion 5. When the user lies flat, the body pressure is distributed on the two judgment plates with inverted T-shapes and T-slots; 8, supported by the four judgment springs 9. When the user lies on their side, one of the judgment plates with inverted T-shapes and T-slots; 8 is subjected to force, thereby causing the judgment plate with inverted T-shapes and T-slots; 8 to move downward and compress the judgment springs 9.

[0023] Specifically, each of the first switching mechanisms 6 includes a first sealing ring 61, a first conical block 62, a first column 63, a first spring 64, a first fixing ring 65, and a first limiting component. The first sealing ring 61 is fixedly disposed inside the connecting pipe, and the first fixing ring 65 is fixedly disposed on the inverted T-shaped plate and T-groove of the judgment plate below. At the top of the 8, the first spring 64 is fixedly disposed on one side wall of the first fixing ring 65, the first column 63 is inserted into the first fixing ring 65, the first conical block 62 is fixedly disposed at the end of the first column 63, and the first limiting component is disposed at the end of the first column 63.

[0024] Specifically, the first limiting component includes a T-shaped plate 66 and a limiting groove 67. The limiting groove 67 is disposed on the first column 63, and the T-shaped plate 66 is fixedly disposed on the inverted T-shaped plate of the upper judgment plate and the T-shaped groove. At the bottom, the T-shaped plate 66 and the limiting groove 67 are slidably engaged. When the user lies flat, the T-shaped plate 66 remains stationary. At this time, the air pressure inside the first air cushion 3 increases, and the gas in the first air cushion 3 pushes the first conical block 62 to move, so that the limiting groove 67 is inserted into the T-shaped plate 66. At this time, the gas inside the first air cushion 3 enters the third air cushion 5 through the gap between the first conical block 62 and the first sealing ring 61. This achieves adaptive inflation of the third air cushion 5 according to the user's lying position, thereby increasing the hardness of the third air cushion 5, providing sufficient support for the waist, and protecting the user's lumbar spine.

[0025] Specifically, each of the second switching mechanisms 7 includes a second conical block 71, a second sealing ring 72, a second column 73, a second spring 74, two second fixing rings 75, and a second limiting assembly. The second sealing ring 72 is fixedly disposed inside the connecting pipe, and one of the second fixing rings 75 is fixedly disposed on the inverted T-shaped plate and the T-groove of the judgment plate. The second column 73 is inserted into the middle of the second fixing ring 75, the second conical block 71 is fixedly disposed at the end of the second column 73, the other second fixing ring 75 is fixedly disposed on the second column 73, the second spring 74 is fixedly disposed between the two second fixing rings 75, and the second limiting assembly is disposed at the end of the second column 73.

[0026] Specifically, each of the second limiting components includes an inverted T-plate and a T-slot. The inverted T-plate is fixedly installed on the upper judgment plate. The T-slot is installed on the second column 73 at the bottom, and the inverted T-plate and the T-slot are inserted into each other. When the user lies on their side, the corresponding judgment board (inverted T-shaped plate and T-groove) is activated based on the patient's sleeping position; 8 moves downward, causing the inverted T-shaped plate to move downward and exit from the T-groove. At this time, the second column 73 is released from its limit, increasing the pressure on the third air cushion 5. This causes the gas inside the third air cushion 5 to push the second cone block 71 and the second column 73 to move, allowing the gas inside the third air cushion 5 to enter the first air cushion 3 through the gap between the second cone block 71 and the second sealing ring 72. This reduces the amount of gas inside the third air cushion 5, making it softer and increasing its contact area with the body. This achieves the distribution of pressure on the patient, avoiding excessive pressure that could lead to pressure sores. It automatically judges the patient's posture and adaptively adjusts the air cushion inflation based on the user's posture, exhibiting a high degree of automation and wide applicability.

[0027] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
