Description

Technical Field

[0001] This application relates to the field of nursing aids technology, and more specifically, to a turning-over aid device. Background Technology

[0002] In clinical nursing, long-term bedridden patients need to be turned regularly to prevent pressure sores and improve blood circulation. However, traditional manual turning methods are difficult to perform, labor-intensive, and pose safety risks. To address this issue, various turning aids have been developed, whose core structure typically includes a support pad, fixation straps, and a turning drive mechanism. However, clinical practice has revealed significant technical defects in existing turning aids, specifically: insufficient fit between the aid and the patient's legs.

[0003] Existing equipment often uses standardized curved support surfaces or rigid fixed structures, failing to fully consider individual differences in the physiological curves of different patients' legs (such as knee flexion angle and calf contour). During the turning process, the support surface cannot achieve dynamic contact with the leg, resulting in uneven pressure distribution on the contact surface, which can easily lead to local skin pressure injuries. At the same time, insufficient friction can cause the equipment to shift.

[0004] Traditional bandage-based immobilization systems often employ single-point or double-point fixation. Under the shearing force of turning over, the bandages are prone to displacement due to elastic fatigue or loosening of the buckles. Especially for patients with edema or cases where the degree of limb swelling changes significantly, existing immobilization systems lack adaptive adjustment capabilities, leading to frequent interruptions during turning to re-immobilize, significantly reducing nursing efficiency. Utility Model Content

[0005] Based on the above problems, this application proposes a turning assist device to solve the technical problem of insufficient fit between the turning assist device and the patient's legs.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0007] A turning-over assist device includes a main body with two fixed openings arranged symmetrically. Each fixed opening is provided with a fixed airbag. The main body is provided with a fixed cylindrical airbag. An air pump is provided inside the main body. The air pump is connected to the fixed cylindrical airbag and the fixed airbag respectively through a conduit.

[0008] In one specific implementation, the fixed cylindrical airbag is located between the two fixed openings for securing the inside of the leg.

[0009] In one specific implementation, the lower part of the fixed opening is arc-shaped, the shape of the fixed airbag is adapted to the lower part of the fixed opening, and the fixed airbag is installed on the side of the fixed opening away from the fixed cylindrical airbag.

[0010] In one specific implementation, slots are provided on both sides of the main body, and each slot is provided with a fixing hook for fixing the main body.

[0011] In one specific implementation, the upper portion of the fixed opening is a plane on the side away from the fixed cylindrical airbag.

[0012] In one specific implementation, the fixed cylindrical airbag can be configured as cylindrical or elliptical.

[0013] In one specific implementation, the vertical distance between the bottom of the body and the lowest edge of the fixed opening is 30mm-60mm.

[0014] The positive effects of this utility model are:

[0015] The device features two symmetrically arranged fixed openings, with the lower part of each opening designed in an arc shape. This design mimics the natural curve of the human leg, providing an initial form fit for the leg.

[0016] Each fixed opening is equipped with a fixed airbag, the shape of which matches the arc shape at the bottom of the fixed opening. More importantly, the device contains an air pump that inflates the fixed airbag through a tube. By adjusting the air pressure inside the airbag, the surface of the airbag can perfectly conform to the contour of the patient's leg, achieving a dynamic and personalized fit even in cases of individual differences such as knee flexion or calf size.

[0017] The fixation balloon is inflated by an air pump to create a flexible yet strong fixation. This fixation method is not rigid, but rather adaptively adjusts according to the degree of swelling in the patient's limb. Even if the patient's limb experiences edema or changes in the degree of swelling, the balloon can adjust the fixation force by inflating and deflating, maintaining a stable fixation effect at all times.

[0018] The device body also has slots on both sides, with fixing hooks installed in the slots. These fixing hooks can further secure the device to the bed or other fixed structure, providing additional stability for turning over and preventing the device from sliding or shifting.

[0024] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0025] Example

[0026] like Figure 1-2 As shown, a turning-over assist device includes a main body 1 with two fixing openings 2. The vertical distance between the bottom of the main body 1 and the lowest edge of each fixing opening 2 is 30mm-60mm. The two fixing openings 2 are symmetrically arranged, and each fixing opening 2 is provided with a fixing airbag 3. The fixing airbag 3 can be connected to the fixing opening 2 via Velcro or magnets. The fixing cylindrical airbag 4 can be cylindrical or elliptical. The fixing cylindrical airbag 4 is located between the two fixing openings 2 and is used to fix the inner side of the leg.

[0027] A fixed cylindrical airbag 4 is provided on the main body 1, and an air pump 5 is provided inside the main body 1. The air pump 5 is connected to the fixed cylindrical airbag 4 and the fixed airbag 3 through conduits 8. The lower part of the fixed opening 2 is arc-shaped, and the upper part of the fixed opening 2, away from the fixed cylindrical airbag 4, is flat. The shape of the fixed airbag 3 is adapted to the lower part of the fixed opening 2, and the fixed airbag 3 is installed on the side of the fixed opening 2 away from the fixed cylindrical airbag 4.

[0028] The patient's legs are placed into the two fixed openings 2 on the main body 1, with the inside of the legs facing the fixed cylindrical airbag 4. The air pump 5 inside the main body 1 is activated, and air is injected into the fixed airbag 3 and the fixed cylindrical airbag 4 through the conduit 8. As the air pressure inside the airbag increases, the fixed airbag 3 gradually inflates, and its shape matches the arc-shaped design at the bottom of the fixed opening 2, so that the surface of the airbag can closely conform to the contour of the patient's leg, especially the physiological curves of the knee joint and calf.

[0029] The fixed cylindrical airbag 4 located between the two fixed openings 2 inflates simultaneously, applying appropriate pressure to the inside of the leg and forming a clamping force with the fixed airbag 3 to further fix the position of the leg.

[0030] Both sides of the main body 1 are provided with slots 6, and each slot 6 is provided with a fixing hook 7 for fixing the main body 1. The fixing hooks 7 in the slots 6 on both sides of the main body 1 are used to fix the entire device to the bed or other fixed structure to prevent the device from sliding or shifting during the turning process.

[0031] After the device stabilizes and secures the patient's legs, turning can be performed with the help of an external turning mechanism or manual assistance. During the turning process, the fixation airbag 3 and the fixation cylindrical airbag 4 continuously provide stable support and fixation, ensuring that the legs remain in close contact with the device.

[0032] Depending on the patient's comfort or nursing needs, the air pressure inside the air bag can be adjusted via air pump 5 to fine-tune the fixation force. After turning the patient, the air bag can be deflated for easy disassembly of the device and for daily patient care.

[0033] With its inflatable, fixed airbag 3 and airbag shape adapted to the arc-shaped design of the lower part of the fixed opening 2, the device can perfectly conform to the physiological curve of the patient's leg, achieving a personalized dynamic fit. This effectively avoids the risk of local skin pressure injury caused by insufficient fit in traditional devices, while also enhancing friction and preventing device displacement.

[0034] The combination of the adaptive fixation airbag 3 system and the clamping force of the fixation cylindrical airbag 4, along with the dual fixation mechanism of the auxiliary fixation hook 7, significantly improves the reliability of fixation. Even under the shearing force of turning over, the device maintains a stable fixation effect, reducing the interruption of operation due to equipment loosening during nursing care and improving nursing efficiency.

[0035] The adaptive fixation airbag 3 is designed to adapt to limbs with varying degrees of swelling, especially for patients with edema. By adjusting the air pressure inside the airbag, the fixation force can be adaptively adjusted, expanding the device's applicability.

[0036] The fixed cylindrical airbag 4 is located between the two fixed openings 2, and its position and shape are designed to simulate the natural movement trajectory of the human leg during the rolling over process to a certain extent. Combined with a stable fixation mechanism, the device provides more ergonomic support for the legs, helping to reduce the risk of secondary injuries such as joint dislocation caused by the misalignment of the support line.

[0037] The device is compact and easy to operate. Rapid fixation and release can be achieved by adjusting the air pressure in the airbag using the air pump 5. At the same time, the soft surface of the airbag improves patient comfort and reduces the discomfort associated with traditional rigid fixation devices.
