Description

Technical Field

[0001] This utility model relates to the field of medical equipment technology, specifically a turning pillow that facilitates adjustment of spinal curvature. Background Technology

[0002] With the accelerating aging of the population, the number of long-term bedridden individuals, such as postoperative recoveries and paralyzed patients, is gradually expanding. Due to their limited ability to move independently, these individuals find it difficult to turn over independently. Traditional manual assistance for turning over not only consumes a lot of energy for caregivers, but also makes it difficult to accurately control the angle and frequency of turning, which can easily lead to complications such as pressure sores and joint stiffness, posing a dual challenge to both patient health and nursing care. Against this backdrop, the turning pillow has been developed as a targeted auxiliary nursing tool. It aims to provide stable support for bedridden individuals through an ergonomic design, helping them to adjust their position more easily, relieving nursing pressure, and reducing health risks.

[0003] However, for post-spinal surgery patients, especially those who have undergone open surgery, existing turning pillows still have significant limitations. These patients need to strictly maintain the physiological curvature of the spine after surgery to ensure that the spine is in a neutral and straight position when turning over, so as to avoid internal fixation displacement, wound traction, or spinal cord nerve damage caused by twisting or lateral bending. However, traditional turning pillows mostly use a single arc or flat design, which cannot accurately match the natural curves of different segments of the spine. When turning over, local suspension or excessive pressure is easy to occur, making it difficult to achieve overall linear stability of the spine and posing potential risks to the patient's recovery.

[0004] Therefore, this utility model provides a turning pillow that facilitates adjustment of the spinal curvature to solve the above problems. Utility Model Content

[0005] To address the shortcomings of existing technologies, this invention provides a turning pillow that facilitates adjustment of spinal curvature, thus solving the aforementioned problems.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a turning pillow that facilitates adjustment of spinal curvature, comprising: The turning pillow structure, through its ergonomic design, provides stable support for bedridden individuals; The turning pillow structure includes a turning pillow body; The interior of the turning pillow body is obliquely isolated from the spine position when the human body is lying down. Multiple electric push rods are arranged in a straight line array. The power terminals of these electric push rods are all obliquely inserted into the socket of the electric control module integrated at the corner of the turning pillow body and are controlled by the output of the electric control module. An air pump is installed on the rear side inside the electric control module and is also controlled by the electric control module. The output interface of the air pump is connected to the air bladder through a pipeline, and the air bladder is integrated at the bottom of the turning pillow body.

[0007] Preferably, the sides of the electric push rod output rods are linearly connected with multiple sets of universal joints to move integrally within the main body of the turning pillow, so that after the electric push rod outputs, it can better adapt to and conform to the different curvatures of the human spine with the help of the universal joints.

[0008] Preferably, each group has at least one of the universal joints.

[0009] Preferably, the interior of the turning pillow body has reserved space for the movement of the electric push rod and the universal joint.

[0010] Preferably, the interior of the turning pillow body has a built-in buffer pad at the output end of the electric push rod and the position where it contacts the human spine.

[0011] Preferably, the electronic control module includes a microcontroller and a drive circuit for controlling the electric actuator and the air pump.

[0012] Preferably, the interior of the turning pillow body has a placement groove in the lumbar surgery area for guiding the drainage tube. Beneficial effects

[0013] This invention provides a turning pillow that facilitates adjustment of spinal curvature. Compared with existing technologies, it has the following advantages: (1) This turning pillow, which is easy to adjust the curvature of the spine, sets multiple electric push rods arranged in a straight line array inside the main body of the turning pillow corresponding to the position of the human spine, and connects them linearly with multiple sets of universal joints. This allows the electric push rods to extend and retract independently and the universal joints to bend flexibly to adapt to different output lengths, thereby accurately conforming to the natural curvature of different segments of the human cervical spine, thoracic spine, lumbar spine, etc. This solves the problem that traditional turning pillows cannot match the curves of different segments of the spine due to their single arc design, avoids local suspension or excessive pressure, achieves linear and stable support of the entire spine, and reduces the rehabilitation risks such as postoperative internal fixation displacement and wound traction.

[0014] (2) The turning pillow that is easy to adjust the curvature of the spine can control the air pump to inflate and deflate the air bag at the bottom through the electronic control module, so that the overall tilt angle of the turning pillow can be flexibly adjusted. It can not only assist the bedridden person to complete the turning action, reduce the physical exertion of the caregiver and accurately control the turning angle, reduce the risk of complications such as pressure sores and joint stiffness, but also adapt to people of different body types, ensuring that the electric push rod acts more accurately on the spine and improve the adaptability of use.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figures 1-4 A turning pillow that facilitates adjustment of spinal curvature, comprising: The turning pillow structure 1 provides stable support for bedridden people through its ergonomic design; The turning pillow structure 1 includes a turning pillow body 11; The interior of the main body 11 of the turning pillow contains multiple electrically operated rods 112 arranged in a straight line, inclined to isolate the spine when the user is lying down. The sides of the output rods of these electrically operated rods 112 are linearly connected to multiple sets of universal joints 113, allowing for integrated movement within the main body 11. This allows the electrically operated rods 112 to better adapt to and conform to different curvatures of the human spine after outputting their power. Each set includes at least one universal joint 113. The interior of the main body 11 provides initial space for the electrically operated rods 112 and universal joints 113. A buffer pad 114 is built into the interior of the main body 11 from the output end of the electrically operated rods 112 to the point of contact with the human spine. The power terminals of these electrically operated rods 112 are obliquely inserted into an integrated electronic control module 1 at the corner of the main body 11. Inside socket 2, and controlled by the output of the electronic control module 12, the electronic control module 12 has a socket for external electrical connection, and an air pump 121 is installed on the rear side inside, and the air pump 121 is also controlled by the electronic control module 12. The electronic control module 12 has a microcontroller and drive circuit for controlling the electric push rod 112 and the air pump 121. As the core control unit of the electric push rod 112 and the air pump 121, the core function of the electronic control module 12 depends on the collaborative architecture of "microcontroller + drive circuit". A complete control link is formed through signal processing, power amplification and closed-loop feedback. The output interface of the air pump 121 is connected to the air bag 13 through the pipeline, and the air bag 13 is integrally set at the bottom of the turning pillow body 11. The interior of the turning pillow body 11 has a tube placement groove 111 for guiding the drainage tube in the lumbar surgery area.

[0019] When adjusting the spinal curvature, the electronic control module 12 receives control commands and controls multiple linear array electric push rods 112 corresponding to the spinal position within the main body 11 of the turning pillow to extend and retract independently. Because the electric push rods 112 are tilted and built inward, the output rod side is linearly connected via multiple sets of universal joints 113. When extending and retracting, the universal joints 113 can bend to adapt to the output length, allowing the output ends of multiple electric push rods 112 to precisely adapt to the natural curvature of the cervical, thoracic, and lumbar vertebrae with the universal joints 113 in an arc-like motion. The padding 114 cushions and avoids discomfort from hard contact, achieving a close fit and support. In terms of turning assistance, the electronic control module 12 controls the air pump 121 to inflate and deflate the airbag 13 at the bottom of the main body 11 of the turning pillow to adjust the overall tilt angle to assist turning, while also assisting in adapting to different human bodies, allowing the electric push rods 112 to act more precisely on the spine.

[0020] In summary, by arranging multiple electrically operated push rods 112 arranged in a straight array inside the main body 11 of the turning pillow corresponding to the position of the human spine, and linearly connecting them with multiple sets of universal joints 113, the electrically operated push rods 112 can extend and retract independently, and the universal joints 113 can flexibly bend to adapt to different output lengths. This allows for precise conformity to the natural curvature of different segments of the human spine, such as the cervical, thoracic, and lumbar vertebrae. This solves the problem that traditional turning pillows, due to their single-arc design, cannot match the curves of different segments of the spine, avoiding local suspension or excessive pressure, and achieving overall spinal alignment. The linear and stable support reduces the rehabilitation risks such as postoperative internal fixation displacement and wound traction. The air pump 121, controlled by the electronic control module 12, inflates and deflates the airbag 13 at the bottom of the main body 11 of the turning pillow, allowing for flexible adjustment of the overall tilt angle of the turning pillow. This not only assists bedridden patients in turning over, reducing the physical exertion of caregivers and allowing for precise control of the turning angle, thus reducing the risk of complications such as pressure sores and joint stiffness, but also adapts to different body types, ensuring that the electric push rod 112 acts more accurately on the spine, improving usability.

[0021] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0022] Working Principle: When adjusting spinal curvature, the microcontroller and drive circuit of the electronic control module 12 first receive control commands (such as preset programs or manual operation signals) to control the independent extension and retraction of multiple electric push rods 112 arranged in a linear array inside the main body 11 of the turning pillow, corresponding to the position of the human spine. Because the electric push rods 112 are tilted internally and their output rods are linearly connected to the sides via multiple sets of universal joints 113, and because the main body 11 of the turning pillow has reserved initial space for movement, when the electric push rods 112 extend or retract, the universal joints 113 can flexibly match the output length of the electric push rods 112 through a certain bending angle. This allows the output ends of multiple electric push rods 112 to work in conjunction with the universal joints 113 at the position of the turning pillow 11 and the human spine in an arc-like undulating manner, precisely adapting to the natural curvature of different segments of the human spine, such as the cervical, thoracic, and lumbar vertebrae. Simultaneously, the electric push rods 112 output... The pad 114 at the point of contact with the human body acts as a buffer to avoid discomfort caused by hard contact and to achieve close support for the spine. For turning assistance, the electronic control module 12 controls the air pump 121 to work. The air pump 121 inflates or deflates the airbag 13 at the bottom of the turning pillow body 11 through the pipeline. When the airbag 13 inflates, it can raise the turning pillow body 11 on the corresponding side, and when it deflates, it lowers it, thereby adjusting the overall tilt angle of the turning pillow to assist the bedridden person in completing the turning action. The above-mentioned movement of the airbag 13 can also help the turning pillow body 11 to adapt to different human bodies, so that the electric push rod 112 can act more accurately on the position of the human spine. In addition, the insertion groove 111 of the lumbar surgery area inside the turning pillow body 11 can guide the drainage tube to pass through, avoiding the drainage tube being compressed or entangled, ensuring smooth postoperative drainage without affecting the support and adjustment functions.

[0023] It should be noted that in actual operation, the electronic control module 12 forms a complete control closed loop of "command input - signal processing - power drive - status feedback": external control commands are parsed by the microcontroller (STM32F407VGT6 can be selected) to generate target control parameters (such as the target position of the push rod and the target pressure of the air pump); the drive circuit (the electric push rod 112 can be a DRV8833 module and the air pump 121 can be a DRV10970 chip) converts the control signal into an actuator drive signal, driving the electric push rod 112 and the air pump 121 to perform corresponding actions; the microcontroller collects feedback parameters through the encoder (Omron E6B2-CWZ6C can be selected) (position feedback) and the pressure sensor (MPX5700DP can be selected), compares them with the target parameters, and then dynamically adjusts the output signal through the PID algorithm until the actuator reaches the target working state, thereby realizing high-precision and high-stability automatic control.

[0024] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.
