Description

Technical Field

[0001] This utility model belongs to the field of medical equipment technology for preventing pressure ulcers, and relates to a pressure ulcer prevention bed. Background Technology

[0002] Stroke patients often require prolonged bed rest due to impaired brain function, and most lose the ability to move independently. During bed rest, uneven pressure on certain parts of the body can easily lead to pressure sores. Pressure sores are localized injuries caused by continuous pressure or pressure combined with shear force applied to the skin and underlying tissues. While hospital beds typically employ specially designed pressure-resistant measures to prevent pressure sores, these measures often only provide localized protection and fail to provide comprehensive pressure regulation for all areas in contact with the bed, thus making it difficult to prevent pressure sores from developing. Summary of the Invention

[0003] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing an anti-pressure ulcer bed that can effectively prevent the development of pressure ulcers in patients.

[0004] The objective of this utility model can be achieved through the following technical solution: a pressure ulcer prevention bed, comprising:

[0005] Base plate, on which a control cabinet is mounted;

[0006] The bed is movably mounted above a base plate. The base plate is equipped with a first adjuster, a second adjuster, and a third adjuster for adjusting the posture of the bed. The first adjuster, the second adjuster, and the third adjuster are all electrically connected to the control cabinet. Multiple pressure sensors are arranged in a rectangular array on the bed, and each pressure sensor is electrically connected to the control cabinet.

[0007] In the aforementioned pressure ulcer prevention bed, the top of the first regulator is connected to an adjustment plate, which is connected to the bottom surface of the bed. The tops of the second regulator and the third regulator are also connected to the adjustment plate.

[0008] In the aforementioned pressure ulcer prevention bed, the first, second, or third adjuster each includes an electric push rod with one end hinged to the base plate, and an adaptation component is movably mounted on the other end of the electric push rod. The adaptation component is movable relative to the electric push rod, and each adaptation component is connected to an adjustment plate.

[0009] In the aforementioned pressure ulcer prevention bed, the bottom plate is provided with a bottom connecting block for mounting an electric push rod, and the bottom connecting block and the electric push rod are connected by a third rotating shaft.

[0010] In the aforementioned pressure ulcer prevention bed, there is a first angle between the extension line of the third rotating shaft of the first regulator and the extension line of the third rotating shaft of the second regulator; there is a second angle between the extension line of the third rotating shaft of the first regulator and the extension line of the third rotating shaft of the third regulator; and there is a third angle between the extension line of the third rotating shaft of the second regulator and the extension line of the third rotating shaft of the third regulator, wherein the first angle, the second angle, and the third angle are all the same and are all 60°.

[0011] In the aforementioned pressure ulcer prevention bed, the adaptor of the third regulator is located on the center line of the adjustment plate in the length direction, and the adaptors of the first regulator and the second regulator are located on both sides of the center line.

[0012] In the aforementioned pressure ulcer prevention bed, the adaptation of the first regulator and the adaptation of the second regulator are symmetrical about the center line.

[0013] In the aforementioned pressure ulcer prevention bed, a lifting rod for connecting an adapter is movably mounted on the electric push rod.

[0014] In the aforementioned pressure ulcer prevention bed, each of the aforementioned adaptation components includes a connecting plate movably connected to the top end of a lifting rod, and a top connecting block is rotatably connected to the connecting plate.

[0015] In the aforementioned pressure ulcer prevention bed, the two ends of the connecting plate are hinged to the lifting rod via a first rotating shaft. The connecting plate is provided with a second rotating shaft for movably connecting the top connecting block, and the first rotating shaft and the second rotating shaft are perpendicular to each other.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. In this utility model, when the patient lies on the bed, each pressure sensor will constantly read the pressure of the patient on the bed and generate corresponding electrical signals to transmit to the control cabinet. At this time, the control cabinet will compare each electrical signal with the preset value. When the value of a certain pressure sensor is greater than the preset value, the control cabinet will control the first regulator, the second regulator and the third regulator to perform corresponding actions, so that the bed will flip in the length direction or in the width direction. In this way, the force of the patient's part on the bed can be reduced, and pressure sores can be avoided. Secondly, the anti-pressure sore bed can also realize the automatic adjustment of the pressure points of the patient.

[0018] 2. By using the first, second, and third regulators in combination, and by connecting the adjustment plate to the bed frame, comprehensive pressure adjustment can be achieved in all areas of the bed frame, thereby preventing pressure sores.

[0019] 3. By setting the first, second, and third included angles, it is ensured that the adjustment board will not tip over under the pressure of the bed body in any state, thus giving the hospital bed good posture stability. Attached Figure Description

[0021] Figure 2 yes Figure 1 Exploded view.

[0022] Figure 3 This is a diagram showing the arrangement of the first, second, and third regulators on the base plate.

[0023] Figure 4 This is a schematic diagram of the third regulator. Detailed Implementation

[0024] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0025] like Figure 1 — Figure 4 As shown, the present invention provides a pressure ulcer prevention bed, which includes a base plate 100, a control cabinet 110, a bed body 500, a first regulator 200, a second regulator 300, a third regulator 400, and a pressure sensor 510.

[0026] A control cabinet 110 is mounted on a base plate 100. A bed 500 is movably mounted above the base plate 100. The base plate 100 is equipped with a first adjuster 200, a second adjuster 300, and a third adjuster 400 for adjusting the posture of the bed 500. All three adjusters are electrically connected to the control cabinet 110. Multiple pressure sensors 510 are arranged in a rectangular array on the bed 500. Each pressure sensor 510 is electrically connected to the control cabinet 110. When the patient lies on the bed 500, each pressure sensor 510... The device 10 continuously reads the pressure exerted by the patient on the bed 500 and generates corresponding electrical signals, which are then transmitted to the control cabinet 110. The control cabinet compares each electrical signal with the preset values. When the value of a certain pressure sensor 510 is greater than the preset value, the control cabinet 110 controls the first regulator 200, the second regulator 300, and the third regulator 400 to perform corresponding actions, thereby causing the bed 500 to flip in the length direction or in the width direction. This reduces the force exerted by the patient on the bed 500 at that location, preventing pressure sores from forming in that area.

[0027] The top of the first adjuster 200 is connected to an adjusting plate 600, which is connected to the bottom surface of the bed 500. The tops of the second adjuster 300 and the third adjuster 400 are also connected to the adjusting plate 600. The central axis of the adjusting plate 600 in the length direction is on the same vertical plane as the central axis of the bed 500 in the length direction, and the central axis of the adjusting plate 600 in the width direction is on the same vertical plane as the central axis of the bed 500 in the width direction. Thus, when the adjusting plate 600 is connected to the bed 500 and the first adjuster 200, the second adjuster 300 and the third adjuster 400 adjust the posture of the adjusting plate 600, the bed 500 will rotate synchronously with the adjusting plate 600 to adjust the center of gravity of the patient's body, thereby avoiding excessive pressure concentration or prolonged pressure concentration in a certain part of the patient's body.

[0028] The first regulator 200, the second regulator 300, or the third regulator 400 all include an electric push rod 210 with one end hinged to the base plate 100. An adapter 220 is movably mounted on the other end of the electric push rod 210. Each adapter 220 is connected to the adjustment plate 600. When the control cabinet 110 controls the corresponding electric push rod 210 to work, the electric push rod 210 will drive the corresponding adapter 220 to rise and fall relative to the electric push rod 210, so as to change the posture of the adjustment plate 600.

[0029] Furthermore, the base plate 100 is provided with a bottom connecting block 211 for mounting the electric push rod 210. The bottom connecting block 211 and the electric push rod 210 are connected by a third rotating shaft 212. The extension line of the third rotating shaft 212 of the first adjuster 200 and the extension line of the third rotating shaft 212 of the second adjuster 300 have a first included angle (not shown in the figure); the extension line of the third rotating shaft 212 of the first adjuster 200 and the extension line of the third rotating shaft 212 of the third adjuster 400 have a second included angle (not shown in the figure); the third rotating shaft 212 of the second adjuster 300... The extension line of the rotating shaft 212 and the extension line of the third rotating shaft 212 of the third adjuster 400 have a third included angle (not shown in the figure). The first included angle (not shown in the figure), the second included angle (not shown in the figure), and the third included angle (not shown in the figure) are all the same and all 60°. Specifically, the adaptor 220 of the third adjuster 400 is located on the center line of the adjusting plate 600 in the length direction. The adaptors 220 of the first adjuster 200 and the second adjuster 300 are located on opposite sides of this center line. The adaptor 220 and the adaptor 220 of the second adjuster 300 are symmetrical about the center line. Through the above structure, when the first adjuster 200 and the second adjuster 300 are stationary, and the third adjuster 400 pushes the adaptor 220 up or down, the adjusting plate 600 and the bed body 500 will rotate along the length of the bed body 500 to transfer the patient's contact pressure with the bed in the front-to-back direction, i.e., adjust the bed's tilt angle. When the first adjuster 200 is stationary, and the second adjuster 300 and the third adjuster 400 simultaneously push the corresponding adaptor 220 up or down, the adjusting plate 600 and the bed body 500 will rotate along the length of the bed body 500. When the adaptor 220 rises or falls, the adjusting plate 600 and the bed 500 will flip in the width direction of the bed 500, which can realize the transfer of pressure in the left and right direction, that is, adjust the first roll angle of the hospital bed; similarly, when the second adjuster 300 is stationary, and the first adjuster 200 and the third adjuster 400 simultaneously push the corresponding adaptor 220 to rise or fall, the adjusting plate 600 and the bed 500 will flip in the width direction of the bed 500, which can realize the transfer of pressure in the left and right direction, that is, adjust the second roll angle of the hospital bed.

[0030] Furthermore, by setting the first included angle (not marked in the figure), the second included angle (not marked in the figure), and the third included angle (not marked in the figure), it is ensured that the adjustment plate 600 will not tip over under the pressure of the bed body 500 in any state, thereby giving the hospital bed good posture stability.

[0031] Furthermore, when the pressure sensor 510, whose detection result exceeds the preset value, is located on the central axis of the bed board along its length, the control cabinet 110 will adjust the tilt angle of the bed. When the pressure sensor 510, whose detection result exceeds the preset value, is located on one side of the bed board along its length and close to the first adjuster 200, the first adjuster 200 and the third adjuster 400 work simultaneously to adjust the second roll angle of the bed. When the pressure sensor 510, whose detection result exceeds the preset value, is located on one side of the bed board along its length and close to the second adjuster 300, the second adjuster 300 and the third adjuster 400 work simultaneously to adjust the first roll angle of the bed.

[0032] A lifting rod 213 for connecting the adapter 220 is movably mounted on the electric push rod 210. When the electric push rod 210 drives the lifting rod 213 to rise or fall relative to the electric push rod 210, the adapter 220 can rise or fall relative to the electric push rod 210 because the lifting rod 213 is connected to the adapter 220.

[0033] Each of the aforementioned adaptors 220 includes a connecting plate 221 movably connected to the top end of the lifting rod 213. A top connecting block 223 is rotatably connected to the connecting plate 221. The flipping direction of the connecting plate 221 is perpendicular to the flipping direction of the top connecting block 223. Specifically, both ends of the connecting plate 221 are hinged to the lifting rod 213 via a first rotating shaft 222. The connecting plate 221 is provided with a second rotating shaft 224 for movably connecting the top connecting block 223. Thus, the connecting plate 221 will rotate relative to the lifting rod 213 around the first rotating shaft 222, and the top connecting block 223 will rotate relative to the connecting plate 221 around the second rotating shaft 224. Furthermore, since the first rotating shaft 222 and the second rotating shaft 224 are perpendicular to each other, the flipping direction of the connecting plate 221 and the flipping direction of the top connecting block 223 can be made perpendicular to each other.

[0034] Furthermore, each of the first rotating shafts 222 is parallel to the central axis of the adjusting plate 600 in the length direction, and each of the second rotating shafts 224 is perpendicular to the central axis of the adjusting plate 600 in the length direction. Therefore, when people adjust the pitch angle or roll angle of the hospital bed, the top connecting block 223 can be adaptively rotated relative to the connecting plate 221. At the same time, the connecting plate 221 can also be adaptively rotated relative to the lifting rod 213, thereby avoiding stress between the lifting rod 213 and the adjusting plate 600.

[0035] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0036] Furthermore, in this utility model, the use of terms such as "first," "second," and "a" is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this utility model, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0037] In this utility model, unless otherwise explicitly specified and limited, the terms "connection," "fixing," etc., should be interpreted broadly. For example, "fixing" can mean a fixed connection, a detachable connection, or an integral part; it can mean a mechanical connection or an electrical connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0038] Furthermore, the technical solutions of the various embodiments of this utility model can be combined with each other, but only if they are based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.
