Description

Technical Field

[0001] This utility model relates to the field of medical devices, specifically to an air mattress for assisting in turning over. Background Technology

[0002] Pressure ulcers are mainly related to external factors such as pressure, shear force, friction, and moisture, with pressure and duration being the most important contributing factors. When patients remain in one position for extended periods, microcirculation in the skin and muscles is obstructed. Currently, equipment used to prevent pressure ulcers primarily includes turning beds and inflatable mattresses. These are used to regularly turn and elevate bedridden patients, or to inflate and deflate air mattresses to change pressure points, avoid pressure concentration, increase airflow to affected areas, and promote blood circulation, thus reducing pressure ulcers and other complications. However, existing equipment cannot accommodate various lying positions for critically ill patients who are bedridden for extended periods, resulting in unsatisfactory outcomes and requiring significant nursing care. Therefore, there is a need for a turning air mattress that can assist with turning and adjust the patient's lying position. Utility Model Content

[0003] The present invention aims to provide an air mattress for assisting in turning over, which can assist in turning over and adjust the patient's lying posture.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: an air mattress for assisting turning over, comprising a bed frame and an air mattress placed on the bed frame. The bed frame includes a support frame and a bed board mechanism disposed on the support frame. The bed board mechanism includes an upper support part and a lower support part. The upper support part includes a middle support plate and two side flaps respectively hinged to both sides of the middle support plate. The support frame is also provided with a first flap mechanism for rotating the side flaps.

[0005] The beneficial effects of this plan are:

[0006] The aforementioned support structure primarily supports the patient's upper body. The central support board provides stable support, ensuring comfort while lying down. Side-turning panels on either side of the central support board allow adjustment to a comfortable angle and lying position. Regular turning helps alleviate muscle tension and circulatory problems caused by static bed rest, especially for critically ill patients. Turning can effectively prevent complications such as deep vein thrombosis and lung infections. The first turning panel mechanism makes turning easier for caregivers, reducing the labor intensity of manual turning, and also facilitates patients' independent turning and getting out of bed. The air cushion automatically adjusts pressure distribution according to changes in the patient's position, preventing prolonged pressure on any one area and reducing the risk of bedsores caused by excessive pressure. It ensures even support for all parts of the patient's body, effectively reducing the risk of localized blood circulation obstruction.

[0007] Preferably, as an improvement, the first flip-plate mechanism includes a lead screw, a guide rod, and a wedge block. One end of the lead screw is inserted into and rotatably connected to the central support plate, and the other end of the lead screw is rotatably connected to the support frame. Guide rods are provided on both sides of the lead screw, and the two ends of the guide rods are fixedly connected to the central support plate and the support frame, respectively. The middle part of the wedge block is threadedly connected to the lead screw, and both ends of the wedge block are slidably engaged with the guide rods.

[0008] The beneficial effects are as follows: When in use, the flipping angle of the side flap can be adjusted by pushing the wedge block to slide. Specifically, the rotation of the lead screw drives the wedge block to slide along the guide rod. The wedge block lifts the side flap and drives the side flap to rotate around the hinge point, thereby adjusting the rotation angle of the flipping plate. This allows for precise adjustment of the flipping angle during operation, ensuring a smooth and comfortable flipping process. The two ends of the guide rod are fixedly connected to the middle support plate and the support frame, respectively, ensuring the stability of the wedge block's movement path.

[0009] Preferably, as an improvement, the bottom surface of the side flap is an inclined surface, and the upper surface of the wedge block is an inclined surface that matches the bottom surface of the side flap.

[0010] The beneficial effects are: the inclined plane acts as a guide, allowing the wedge block to smoothly push the side flip plate to flip, making it less prone to jamming during the flipping process, and ensuring the smoothness and stability of the operation.

[0011] Preferably, as an improvement, the end of the lead screw away from the central support plate passes through the support frame and is fixedly connected to a rotating handle.

[0012] The beneficial effects are as follows: when the handle is turned, the lead screw rotates along the thread, thereby pushing the wedge block to precisely adjust the flip angle of the side flip plate, making it convenient for nursing staff to adjust the rotation angle of the side flip plate. Through the design of the lead screw and handle, nursing staff can operate independently and complete the flipping work with less physical effort.

[0013] Preferably, as an improvement, the lower support part includes a lower support plate and a lower flap plate hinged to the lower support plate, and a second flap mechanism is provided under the lower flap plate.

[0014] The beneficial effects are as follows: The lower support provides support for the patient's lower body. By rotating the lower support plate, the patient's legs can be lifted. When the patient has deep vein thrombosis or edema, it can elevate both lower limbs, helping to relieve blood stasis. Elevating the legs promotes venous return, reduces blood pooling, helps improve blood circulation in the legs, prevents or alleviates the formation of deep vein thrombosis, helps relieve edema, reduces swelling in the lower limbs, improves blood circulation and lymphatic return in the lower limbs, and reduces patient discomfort. The rotation of the lower support plate not only helps improve blood circulation in the lower limbs but also provides a more comfortable leg support posture. For patients who are bedridden for a long time, proper leg support can reduce muscle tension and pain caused by being in the same position for a long time, while fixing the lower support plate helps ensure the stability of the patient's lying position.

[0015] Preferably, as an improvement, the air cushion includes a support air cushion and an adjustment air cushion. The support air cushion is placed on the bed board mechanism, and the adjustment air cushion is placed on the support air cushion. The adjustment air cushion includes a middle support air cushion, a bottom support air cushion, a leg support air cushion, and two side support air cushions that are not mutually ventilated. An air pump is provided to supply air to the support air cushion and the adjustment air cushion respectively.

[0016] The beneficial effects are as follows: The supporting air mattress, as the foundation of the air mattress, primarily provides overall support for the patient, ensuring their stability and comfort on the bed. Placed on the bed board mechanism, it plays a role in overall support, providing the patient with a stable lying surface. The adjustable air mattress is placed on top of the supporting air mattress. By adjusting the inflation volume of different parts of the air mattress, the support force for different parts of the patient's body can be adjusted to achieve a more personalized and precise support effect. It can control the inflation volume of each module of the air mattress separately, increasing blood circulation and preventing pressure injuries to the heels, thus promoting disease recovery.

[0017] Preferably, as an improvement, the support air cushion and the adjustment air cushion are attached by Velcro.

[0018] The benefits are: if the air cushion needs to be replaced or cleaned and maintained, the air cushion components can be quickly removed using Velcro, reducing operational complexity and manual labor intensity. Attached Figure Description

[0020] Figure 2 This is a structural schematic diagram of an embodiment of the present utility model. Detailed Implementation

[0021] The following detailed description illustrates the specific implementation method:

[0022] The reference numerals in the accompanying drawings include: support frame 1, middle support plate 2, side flip plate 3, lead screw 4, guide rod 5, wedge block 6, rotating handle 7, lower support plate 8, lower flip plate 9, support air cushion 10, middle support air cushion 11, bottom support air cushion 12, leg support air cushion 13, and side support air cushion 14.

[0023] Example

[0024] The implementation examples are basically as follows Figures 1-2 As shown, Figure 1 The illustrated air mattress for assisting turning over includes a bed frame and an air mattress placed on the bed frame. The bed frame includes a support frame 1 and a bed board mechanism disposed on the support frame 1. The bed board mechanism includes an upper support part and a lower support part. The upper support part includes a middle support plate 2 and two side flip plates 3 respectively hinged to both sides of the middle support plate 2. The support frame 1 is also provided with a first flip plate mechanism for rotating the side flip plates 3. The aforementioned support structure primarily supports the patient's upper body. The central support plate 2 provides stable support to ensure the patient's comfort while lying down. Side-turning plates 3 on either side of the central support plate 2 allow adjustment to a comfortable angle and lying position. Regular turning helps alleviate muscle tension and circulatory problems caused by static bed rest. For critically ill patients, turning can effectively prevent complications such as deep vein thrombosis and lung infections. The first turning plate mechanism makes turning easier for caregivers, reducing the labor intensity of manual turning and facilitating patients to turn over and get out of bed independently. The air cushion automatically adjusts pressure distribution according to changes in the patient's position, preventing prolonged pressure on any one area and reducing the risk of bedsores caused by excessive pressure. This ensures even support for all parts of the patient's body, effectively reducing the risk of localized blood circulation obstruction.

[0025] The first flipping mechanism includes a lead screw 4, a guide rod 5, and a wedge block 6. One end of the lead screw 4 is inserted into and rotatably connected to the central support plate 2, and the other end of the lead screw 4 is rotatably connected to the support frame 1. Guide rods 5 are provided on both sides of the lead screw 4. The two ends of the guide rods 5 are fixedly connected to the central support plate 2 and the support frame 1, respectively. The middle part of the wedge block 6 is threadedly connected to the lead screw 4, and both ends of the wedge block 6 are slidably engaged with the guide rods 5. In use, the flipping angle of the side flipping plate 3 can be adjusted by pushing the wedge block 6 to slide. Specifically, the rotation of the lead screw 4 drives the wedge block 6 to slide along the guide rod 5. The wedge block 6 lifts the side flipping plate 3 and drives the side flipping plate 3 to rotate around the hinge point, thereby adjusting the rotation angle of the flipping plate. This allows for precise adjustment of the flipping angle during operation, ensuring a smooth and comfortable flipping process. The bottom surface of the side-flipping plate 3 is inclined, and the upper surface of the wedge block 6 is also inclined to match the bottom surface of the side-flipping plate 3. The inclined surface serves as a guide, allowing the wedge block 6 to smoothly push the side-flipping plate 3 to flip, making it less prone to jamming during the flipping process and ensuring the smoothness and stability of the operation. The end of the lead screw 4 away from the central support plate 2 passes through the support frame 1 and is fixedly connected to the rotating handle 7. When the handle 7 is turned, the lead screw 4 rotates along the thread, thereby pushing the wedge block 6 to precisely adjust the flipping angle of the side-flipping plate 3. This makes it easy for nursing staff to adjust the rotation angle of the side-flipping plate 3. Through the design of the lead screw 4 and the handle, nursing staff can operate independently and complete the flipping work with less physical effort. The lower support includes a lower support plate 8 and a lower flap 9 hinged to the lower support plate 8. A second flap mechanism is located below the lower flap 9, with the second flap structure being identical to the first flap structure. The lower support supports the patient's lower body. By rotating the lower flap 9, the patient's legs can be raised. When the patient has deep vein thrombosis or edema, this can elevate both lower limbs, helping to alleviate blood stasis. Elevating the legs promotes venous return, reduces blood pooling, helps improve blood circulation in the legs, prevents or alleviates the formation of deep vein thrombosis, helps relieve edema, reduces lower limb swelling, improves blood circulation and lymphatic return in the lower limbs, and reduces patient discomfort. The rotation of the lower flap 9 not only helps improve blood circulation in the lower limbs but also provides a more comfortable leg support posture. For patients who are bedridden for extended periods, appropriate leg support can reduce muscle tension and pain caused by prolonged periods in the same position. Simultaneously, fixing the lower support plate 8 helps ensure the stability of the patient's lying position.

[0026] The air cushion section includes a supporting air cushion 10 and an adjusting air cushion. The supporting air cushion 10 is placed on the bed board mechanism, such as... Figure 1 and Figure 2As shown, the adjustable air cushion is placed on the supporting air cushion 10. The adjustable air cushion includes a central supporting air cushion 11, a bottom supporting air cushion 12, a leg supporting air cushion 13, and two side supporting air cushions 14, all of which are not interconnected. An air pump is provided to supply air to the supporting air cushion 10 and the adjustable air cushion separately. In this embodiment, the supporting air cushion 10 and the adjustable air cushion are connected by Velcro, which allows for quick disassembly of the air cushion components, reducing operational complexity and manual labor intensity. The supporting air cushion 10, as the foundation of the air mattress, mainly provides overall support for the patient, ensuring the patient's stability and comfort on the bed. Placed on the bed board mechanism, it plays a role in overall support, providing the patient with a stable lying surface. The adjustable air cushion is placed on the supporting air cushion 10. The adjustable air cushion consists of multiple tubular air bladders. By adjusting the inflation volume of the air bladders in different parts, the support force for different parts of the patient's body can be adjusted to achieve a more personalized and precise support effect. It can control the inflation volume of each module of the air cushion separately, increasing blood circulation and preventing pressure injuries to the heel, thus promoting disease recovery.
