Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a body position rotation support for critically ill patients. Background Technology

[0002] For patients who are bedridden for extended periods, especially those with severe illnesses who have limited mobility, prolonged pressure on the same part of the body can easily lead to poor blood circulation and cause pressure sores. Pressure sores not only cause great pain to patients but can also lead to serious infections. They are one of the complications that need to be prevented in clinical nursing. In order to effectively prevent the occurrence of pressure sores, medical staff need to turn the patient's body regularly to change their bed position and allow different parts of the body to alternate pressure.

[0003] In existing technologies, turning patients over primarily relies on manual operation by caregivers. This method demands a high level of physical strength from caregivers, especially when dealing with heavy or immobile patients. Often, two or more caregivers are needed, significantly increasing their workload and exposing them to occupational injury risks to the lower back and other areas. Secondly, during manual handling and turning, it's difficult to achieve absolute smoothness and precision. Uneven force or swaying can cause discomfort to the patient, and for critically ill patients or those with wounds, unstable movements can even lead to secondary injuries. Furthermore, after turning the patient to the desired position, pillows or cushions are typically used for support. However, these supports are prone to displacement or compression deformation, making it difficult to maintain a precise support angle for extended periods. This affects the effectiveness of the position adjustment, resulting in significant shortcomings in the current technology regarding ease of operation, precision, and stability of support.

[0004] Because current techniques typically involve manually turning patients over, and the support provided after the patient is turned over is often unstable, the stability of the support is low. Utility Model Content

[0005] This utility model provides a postural repositioning support for critically ill patients, which solves the problem of low support stability in existing technologies. The technical solution is as follows: A repositioning support for critically ill patients includes: a bed board and a repositioning support mechanism. The bed board includes four rotating plates arranged in a rectangular array, with adjacent rotating plates hinged together. The flip support mechanism is located at the bottom of the bed board and includes a support plate and a support device. The support plate is configured to abut against the bottom of any two adjacent rotating plates, and the support device is used to drive the support plate to rise or fall.

[0006] Optionally, the support device includes a hollow disc, a threaded rod, a slider, and a connecting rod. The hollow disc is an upward-opening disc-shaped structure and is disposed at the bottom of the bed board. The support plate is an arc-shaped structure and is disposed in the hollow disc. The bottom of the hollow disc has a groove facing the center of the support plate. The threaded rod is arranged along the length of the groove. The slider is threadedly connected to the threaded rod and is slidably disposed in the groove. One end of the connecting rod is hinged to the slider, and the other end is hinged to the center of the support plate. Both ends of the support plate are rotatably connected to the hollow disc.

[0007] Optionally, a vertical auxiliary support plate is provided inside the hollow disk, the auxiliary support plate is located at both ends of the support plate, and a hinge is provided between the top of the auxiliary support plate and the end of the support plate.

[0008] Optionally, the bottom of the bed board is provided with a first annular groove, and the support plate is slidably disposed in the first annular groove.

Detailed Implementation

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0020] Figure 1 This is a schematic diagram of the overall structure in the initial state provided by an embodiment of the present invention; Figure 2 This is a schematic diagram of the overall structure of the support mechanism provided in this embodiment of the present invention in its working state; Figure 3 This is a schematic diagram of the bed board and support mechanism provided in this embodiment of the utility model; Figure 4 This is a schematic diagram of the support mechanism structure provided in an embodiment of the present utility model; Figure 5 This is an exploded view of the support device provided in an embodiment of this utility model. Figures 1 to 5 The illustrated critical care patient repositioning support includes: a bed board 1 and a repositioning support mechanism 2. The bed board 1 includes four rotating plates 11 arranged in a rectangular array, with adjacent rotating plates 11 hinged together. The repositioning support mechanism 2 is located at the bottom of the bed board 1 and includes a support plate 21 and a support device 22. The support plate 21 is configured to abut against the bottom of any two adjacent rotating plates 11, and the support device 22 is used to drive the support plate 21 to rise or fall.

[0021] Exemplarily, in this embodiment of the invention, the bed board 1 includes four rotating plates 11, namely a first rotating plate 111, a second rotating plate 112, a third rotating plate 113, and a fourth rotating plate 114. The patient lies in the middle of the bed board 1, with the patient's head located on one side of the first rotating plate 111 and the second rotating plate 112, and the patient's feet located on one side of the third rotating plate 113 and the fourth rotating plate 114. Depending on the patient's needs to rotate to different positions, the support plate 21 can be positioned at the bottom of different rotating plates 11. The position of the support plate 21 at the bottom of the bed board 1 can be adjusted manually or mechanically. When the adjusting support plate 21 is at the bottom of the first rotating plate 111 and the second rotating plate 112, the support device 22 is activated, causing the first rotating plate 111 and the second rotating plate 112 to rotate upward, thereby enabling the patient to sit up and reducing pressure on the patient's upper body; when the adjusting support plate 21 is at the bottom of the second rotating plate 112 and the third rotating plate 113, the support device 22 is activated, causing the second rotating plate 112 and the third rotating plate 113 to rotate upward, thereby enabling the patient to turn to the right and reducing pressure on the patient's left side. When the adjusting support plate 21 is located at the bottom of the third rotating plate 113 and the fourth rotating plate 114, the support device 22 is activated, causing the third rotating plate 113 and the fourth rotating plate 114 to rotate upwards, thereby raising the patient's legs and reducing pressure on the patient's lower body. When the adjusting support plate 21 is located at the bottom of the fourth rotating plate 114 and the first rotating plate 111, the support device 22 is activated, causing the fourth rotating plate 114 and the first rotating plate 111 to rotate upwards, thereby allowing the patient to turn to the left, reducing pressure on the patient's right side. The support device 22 can adjust and fix the rotating plate 11 to provide stable bottom support for the patient. The rotating plate 11 has a rigid structure to provide stable bottom support for the patient. A soft cushioning structure such as a mattress can be installed on the rotating plate 11 to reduce the hard contact between the patient's body and the bed board 1. By setting this structure, it is possible to adjust the patient's posture in different ways, allowing the patient to relax different parts of their body and preventing bedsores and other diseases caused by prolonged pressure on a certain body part. Because this structure is used to rotate the patient's body, and the rotating plate 11 is a rigid structure, it can provide stable bottom support for the patient in different postures, thereby improving the support stability of this structure.

[0022] This embodiment of the invention provides a postural repositioning support for critically ill patients. Because four rotating plates 11 are arranged in a rectangular array and adjacent rotating plates 11 are hinged, the support device 22 controls the rise of the support plates 21, allowing adjacent rotating plates 11 to flip simultaneously. This creates an angle between the bed board 1 and the patient. When the patient lies on the bed board 1, different patients can be flipped or bent in different positions, thus preventing bedsores caused by prolonged bed rest in the same position. In this embodiment, because the rotating plates 11 are flipped directly, no manual intervention is required to flip the patient, preventing secondary injury. Compared to traditional technologies that use soft pads or pillows for support, this embodiment uses rotation for patient support, avoiding compression and deformation, effectively solving the problem of low support stability in existing technologies.

[0023] Optionally, the support device 22 includes a hollow disc 221, a threaded rod 222, a slider 223, and a connecting rod 224. The hollow disc 221 is an upward-opening disc-shaped structure and is disposed at the bottom of the bed board 1. The support plate 21 is an arc-shaped structure and is disposed in the hollow disc 221. The bottom of the hollow disc 221 has a groove 225 facing the middle of the support plate 21. The threaded rod 222 is arranged along the length of the groove 225. The slider 223 is threadedly connected to the threaded rod 222 and is slidably disposed in the groove 225. One end of the connecting rod 224 is hinged to the slider 223, and the other end is hinged to the middle of the support plate 21. Both ends of the support plate 21 are rotatably connected to the hollow disc 221.

[0024] Exemplarily, in this embodiment of the present invention, the hollow disc 221 is disposed on the ground or a stable support platform, and the opening of the hollow disc 221 and the support plate 21 provide bottom support for the bed board 1. A knob 228 is fixedly disposed at the end of the threaded rod 222, and the knob 228 is located on the outside of the hollow disc 221. When the knob 228 is rotated, the slider 223 can slide along the threaded rod 222 and the groove 225. Figure 4 As shown, when the knob 228 is rotated, causing the slider 223 to slide towards the support plate 21, the support plate 21 rises under the action of the connecting rod 224, thereby lifting the rotating plate 11. When the knob 228 is rotated, causing the slider 223 to slide away from the support plate 21, the support plate 21 falls under the action of the connecting rod 224. The threads on the threaded rod 222 are made of high-strength steel, and the hinge points at both ends of the connecting rod 224 are also made of high-strength steel, thus enabling the support device 22 to provide stable support for the patient.

[0025] Optionally, a vertical auxiliary support plate 226 is provided inside the hollow plate 221. The auxiliary support plate 226 is located at both ends of the support plate 21, and a hinge 227 is provided between the top of the auxiliary support plate 226 and the end of the support plate 21.

[0026] Exemplary, in embodiments of this utility model, such as Figure 4 As shown, by providing the auxiliary support plate 226, auxiliary support can be provided for the support plate 21, and by providing the hinge 227, the connection strength between the end of the support plate 21 and the auxiliary support plate 226 can be strengthened. On the other hand, by providing the auxiliary support plate 226, the installation height of the support plate 21 can be increased, preventing interference between the threaded rod 222, the slider 223 and the connecting rod 224 during the movement of the support plate 21, thereby improving the stability of this support.

[0027] Optionally, the bottom of the bed board 1 is provided with a first annular groove 12, and the support plate 21 is slidably disposed in the first annular groove 12.

[0028] Exemplary, in embodiments of this utility model, such as Figure 3 As shown, by setting the first annular groove 12, when the support plate 21 is rotated and adjusted to be located at the bottom position of the bed board 1, the support plate 21 can slide along the first annular groove 12, providing guiding force. Furthermore, when the support plate 21 rises to provide support, it contacts not only the bottom of the first annular groove 12 but also the groove wall, increasing the contact area between the support plate 21 and the bed board 1. This allows the support plate 21 to provide a more stable bottom support force for the bed board 1, further improving the stability of the support device.

[0029] Optionally, it also includes a support frame 6, with the bed board 1 disposed on the support frame 6. The support frame 6 has a stepped surface 61, and the bottom edge of the bed board 1 abuts against the stepped surface 61.

[0030] Exemplary, in embodiments of this utility model, such as Figure 2 As shown, the support frame 6 can provide bottom support for the bed board 1. When the rotating plates 11 are all in a horizontal state, the bed board 1 is equivalent to an ordinary bed, and the patient can lie flat on the bed board 1. At this time, the step surface 61 can provide stable support for the bed board 1, thereby further improving the stability of this support device.

[0031] Optionally, a fixing ring 3 is provided at the bottom of the bed board 1, and a second annular groove 31 is provided at the bottom of the fixing ring 3. A limiting protrusion 2211 is provided at the opening of the hollow disc 221, and the limiting protrusion 2211 is slidably disposed in the second annular groove 31.

[0032] Exemplary, in embodiments of this utility model, such as Figure 5As shown, the fixing ring 3 is fixedly installed at the bottom of the support frame 6. Through the cooperation of the second annular groove 31 and the limiting protrusion 2211, it can provide a rotational guiding force when the support plate 21 is rotated and adjusted to the bottom position of the bed board 1, so that the support plate 21 can be adjusted into position more accurately. Furthermore, the fixing ring 3 and the opening of the hollow disk 221 contact and abut against each other, which can provide a stable support force for the bed board 1 that has not been flipped over, thereby improving the structural strength of this support.

[0033] Optionally, a circular ring 4 is sleeved on the outside of the fixed ring 3. The circular ring 4 is slidably mounted on the fixed ring 3. The circular ring 4 is provided with a plurality of slots 41 evenly spaced along the circumference. The side of the hollow disk 221 is provided with a locking block 2212 that matches the slots 41. The locking block 2212 and the slots 41 are inserted and engaged.

[0034] Exemplary, in embodiments of this utility model, such as Figure 5 As shown, there are four slots 41 and four blocks 2212. When the hollow disk 221 needs to be rotated to adjust the position of the support plate 21, the ring 4 is slid upward to separate the blocks 2212 from the slots 41. At this time, the hollow disk 221 and the fixing ring 3 can rotate relative to each other. When the position of the support plate 21 needs to be fixed, the ring 4 is slid downward to make the blocks 2212 and the slots 41 engage, thereby preventing the support plate 21 from rotating in the support state, thus further improving the stability of the support device.

[0035] Optionally, a guide rod 5 is fixedly installed at the bottom of the bed board 1, and a limiting hole 42 matching the guide rod 5 is opened on the ring 4. The ring 4 is slidably installed on the guide rod 5.

[0036] Exemplary, in embodiments of this utility model, such as Figure 3 and Figure 5 As shown, the guide rod 5 is vertically fixed at the bottom of the support frame 6. The cooperation between the guide rod 5 and the limiting hole 42 can provide guiding force for the sliding of the ring 4, thereby further improving the stability of this support.

[0037] Optionally, a spring 51 is provided between the ring 4 and the bottom of the bed board 1, and the spring 51 is sleeved on the guide rod 5.

[0038] Exemplary, in embodiments of this utility model, such as Figure 5 As shown, by setting spring 51, when the ring 4 slides upward, the spring 51 is compressed, and the hollow disk 221 can rotate. When locking is required, the upward pushing force of the ring 4 is released, and under the elastic force of the spring 51, the ring 4 can be pushed back to its original position, so that the locking block 2212 and the locking slot 41 can be inserted and engaged. By setting spring 51, there is no need to apply a downward pushing force to the ring 4, which improves the ease of operation of this support.

[0039] Optionally, a limiting piece 52 is provided at the bottom of the guide rod 5, and the diameter of the limiting piece 52 is larger than the diameter of the limiting hole 42.

[0040] Exemplary, in embodiments of this utility model, such as Figure 5 As shown, by setting the limiting piece 52, the maximum downward sliding stroke of the ring 4 can be limited, preventing the ring 4 from sliding off the guide rod 5, thereby further improving the ease of operation of this support.
