Description

Technical Field

[0001] This utility model relates to the field of medical tools, and in particular to an automatic patient turning mat. Background Technology

[0002] Currently, triangular pillows and other assistive tools are commonly used in clinical nursing to help patients turn over. However, these tools require manual operation by medical staff, and each turn requires 2-3 people working together. This not only consumes a lot of human resources but also easily causes secondary injury to the patient due to improper operation. It is time-consuming and laborious, and it is difficult to accurately control the turning angle. Long-term use can easily lead to patient positional deviation, increasing the risk of pressure sores. Furthermore, the inability to achieve precise angle control often results in deviations in the actual turning angle, which seriously affects position management and makes it difficult to meet the personalized nursing needs in different clinical scenarios.

[0003] Therefore, an automatic patient turning mat was designed. Utility Model Content

[0004] This invention addresses the shortcomings of existing technologies by providing an automatic patient turning mat, which solves the problems of current clinical practice using triangular pillows for turning patients, which is time-consuming, laborious, and prone to causing secondary injuries, leading to patient positional shifts and increasing the risk of pressure sores.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: An automatic patient turning pad includes a turning pad and a control box located on one side of the turning pad for controlling the inflation of different areas. The turning pad consists of two side airbag pads, a central airbag pad, an adjusting airbag pad, and a supporting airbag pad. The airbag pads are connected by wires of different lengths. When inflated, the whole pad presents a state of central concavity and bulging sides, forming a centripetal support structure to keep the patient's body in the center.

[0006] Preferably, the turning pads are symmetrically distributed, and the central airbag pad is located at the center of the two side airbag pads.

[0007] Preferably, the airbag pads on both sides are sparsely arranged longitudinally, and the length of the pads is slightly shorter than the circumference of the airbag when it is naturally inflated. After inflation, the pads are quickly straightened, forcing the airbag to expand outwards preferentially.

[0008] Preferably, the threads of the central airbag cushion are arranged in a dense grid pattern in both longitudinal and transverse directions, with the thread length close to the original size of the airbag. When inflated, the thread grid restricts expansion in both directions, and the cross-section remains flat or slightly concave.

[0009] Preferably, the adjustable airbag cushion and the supporting airbag cushion are located at the bottom of the side airbag cushions and the central airbag cushion; the adjustable airbag cushion is located in the area corresponding to the head for support, and the supporting airbag cushion is located in the area corresponding to the body and feet for support.

[0010] Preferably, the adjustable airbag cushion has a relatively long thread length, but the thread arrangement direction is diagonally crossed towards the head support to enhance local adaptability and increase the expansion degree when inflated; the support airbag cushion has a relatively short thread length, but the transverse threads are denser to suppress lateral sliding of body parts and the deformation is more gradual when inflated.

[0011] Preferably, the interior of the two side airbags, the central airbag, the adjusting airbag, and the supporting airbag is equipped with a pressure sensor for detecting the air pressure in the chamber, and the pressure sensor is electrically connected to the control box.

[0012] Preferably, the surface of the central airbag is provided with a protective pad for contact with the patient's buttocks, and the protective pad is made of a breathable and antibacterial composite material.

[0013] Preferably, the bottom two sides of the protective pad are fixedly provided with Velcro tabs, and the surface two sides of the central airbag pad are fixedly installed with Velcro tabs. The Velcro tabs and Velcro tabs are detachably connected and used to replace the protective pad.

[0014] The turning pad is made of medical-grade silicone with a Shore hardness of 40-50A, which combines flexibility and corrosion resistance.

[0015] Compared with the prior art, the present invention has the following beneficial effects: This invention achieves automatic patient turning and care through wire drawing technology and intelligent control of the control box. Different wire lengths are used to adjust the inflation degree of the airbag in different areas. The wire lengths of the airbag pads on both sides are slightly shorter than the circumference of the airbag when naturally inflated. After inflation, the wires quickly straighten, forcing the airbag to expand outwards preferentially. The longer wires exert less constraint on the airbag, allowing for greater deformation and forming a soft support surface. The central airbag pad uses a dense grid pattern in both longitudinal and transverse directions, with wire lengths close to the original size of the airbag. During inflation, the wire grid restricts expansion in both directions, maintaining a flat or slightly concave cross-section (creating a height difference with the sides). The shorter wires suppress vertical deformation, forming a stable... The support area, when inflated, forms a concave center with bulging sides, creating a centripetal support structure to center the patient's position and solving the problem of slippage that traditional turning pads easily cause. The detachable antibacterial protective pad uses composite antibacterial materials and can be quickly replaced with Velcro. The independently controlled multi-airbags can automatically adjust the support strength according to the patient's body shape. The medical-grade silicone material, which is easy to disinfect and maintain, ensures long-term reliability. At the same time, it reduces the incidence of pressure ulcers, lowers the risk of infection, and shortens the time for turning over, significantly improving the quality of care and patient comfort. It is especially suitable for nursing scenarios for long-term bedridden patients in ICUs, rehabilitation departments, and other similar settings. Attached Figure Description

Example

[0023] Please see Figure 1-5 An automatic patient turning pad includes a turning pad 1 and a control box 2 set on one side of the turning pad 1 for controlling the inflation of different areas. The turning pad 1 is composed of two side airbag pads 11, a central airbag pad 12, an adjusting airbag pad 13 and a supporting airbag pad 14. The airbag pads are connected by wires of different lengths. When inflated, the whole pad presents a state of central depression and bulging sides, forming a centripetal support structure to keep the patient's body in the center. The turning pad 1 is symmetrically distributed. The central airbag pad 12 is located at the center of the two side airbag pads 11. The threads of the side airbag pads 11 are sparsely arranged longitudinally. The length of the threads is slightly shorter than the circumference of the airbag when it is naturally inflated. After inflation, the threads are quickly straightened, forcing the airbag to expand outwards first. The threads of the central airbag pad 12 are a dense grid in both longitudinal and transverse directions. The length of the threads is close to the original size of the airbag. When inflated, the thread grid restricts expansion in both directions. The cross-section remains flat or slightly concave. The adjusting airbag pad 13 and the supporting airbag pad 14 are located at the bottom of the side airbag pads 11 and the central airbag pad 12. The adjustable airbag 13 is located in the head area for support, and the support airbag 14 is located in the body and foot areas for support. The adjustable airbag 13 has longer threads, but the threads are arranged diagonally across the head for support, enhancing local adaptability and resulting in greater expansion when inflated. The support airbag 14 has shorter threads, but the transverse threads are denser to suppress lateral slippage of body parts, resulting in smoother deformation when inflated. Pressure sensors for detecting air pressure in the chambers are installed inside the side airbags 11, the central airbag 12, the adjustable airbag 13, and the support airbag 14. The pressure sensors are electrically connected to the control box 2. The fiber drawing process involves embedding high-strength elastic fiber threads (such as nylon, polyester, or aramid fibers) inside the airbag cushion to directionally constrain the airbag's expansion shape. Its core principle is to limit the airbag's expansion capacity in different directions by controlling the number and direction of the threads per unit area. The ends of the threads are fixed to specific positions on the inner wall of the airbag (usually using thermoforming welding or chemical bonding) to form a predetermined mechanical structure. The system utilizes multiple airbag pads and a control box to achieve a safe and precise automatic turning function. It employs wires of varying lengths; the side airbag pads 11 are sparsely arranged longitudinally (e.g., 5-8 wires per 10cm²), with the wire length slightly shorter than the circumference of the airbag during natural inflation. After inflation, the wires quickly straighten, forcing the airbag to expand outwards preferentially (resulting in a significantly arc-shaped bulge in cross-section). The longer wires exert less constraint on the airbag, allowing for greater deformation and forming a soft support surface. The central airbag pad 12 uses a dense longitudinal and transverse grid (e.g., 5-8 wires per 10cm²). (15-20 threads), the length of the threads is close to the original size of the airbag; when inflated, the thread mesh restricts expansion in both directions, and the cross-section remains flat or slightly concave (forming a height difference with the sides). The shorter threads inhibit vertical deformation and form a stable support area. The two work together to form an overall state with a central depression and bulging sides when inflated, forming a centripetal support structure to keep the patient in a centered position; the adjusting airbag pad 13 is similar to the two side airbag pads 11, with longer threads, but the thread arrangement direction is diagonally crossed towards the head support to enhance local adaptability; the supporting airbag pad 14 is similar to the central airbag pad, with shorter threads, but the transverse threads are denser to inhibit lateral sliding of body parts; Compared to traditional triangular pillows, this significantly reduces body position deviation. The adjustable airbag 13 and the support airbag 14 are inflated differently, with the head area expanding to 180% and the body area to 80%, achieving ergonomic support. Combined with the closed-loop control of the built-in pressure sensor, the turning angle can be reasonably controlled. The control box 2 adjusts the air pressure in each area according to the pressure sensor data, and automatically compensates when pressure imbalance is detected to avoid local pressure exceeding the reasonable threshold. Example

[0024] The surface of the central airbag cushion 12 is provided with a protective pad 3 for contact with the patient's buttocks. The protective pad 3 is made of breathable and antibacterial composite material. The bottom two sides of the protective pad 3 are fixedly provided with Velcro 4. The surface two sides of the central airbag cushion 12 are fixedly provided with Velcro 5. The Velcro 4 and Velcro 5 are detachably connected and used to replace the protective pad 3. The turning pad 1 is made of medical grade silicone with a Shore hardness of 40-50A, which has both flexibility and corrosion resistance. Made of breathable and antibacterial composite material, it can be quickly replaced through Velcro 4 and Velcro 5. Compared with traditional fixed pads, the bacterial growth rate is reduced and it is easy to disinfect and maintain. The protective pad 3 works in synergy with the medical silicone airbag pad with a Shore hardness of 40-50A to ensure both support stability and breathability. This design solves the problems of traditional turning pads that are easy to breed bacteria, difficult to clean and not comfortable enough. It is especially suitable for the nursing needs of long-term bedridden patients.
