Description

Technical Field

[0001] This utility model belongs to the field of medical auxiliary device technology, and specifically relates to a turning pillow with a turnover function. Background Technology

[0002] Patients who are bedridden for extended periods are highly susceptible to pressure ulcers (bedsores) due to prolonged pressure on local tissues and obstructed blood circulation. Pressure ulcers not only cause significant pain, increase the risk of infection, and prolong the recovery period, but also significantly increase the burden of care and economic costs. Therefore, pressure ulcer prevention is one of the core aspects of long-term bedridden care. Regularly turning and changing the patient's position is one of the most basic and effective methods for preventing pressure ulcers. However, a considerable number of patients are unable to turn themselves due to weakness, paralysis, pain, or other reasons. In such cases, caregivers usually need to use assistive devices, such as turning pillows. Existing turning pillows are mainly used for: placing them at a specific position on the patient's side as a fulcrum to help caregivers perform turning movements more effortlessly and accurately; and placing them between the patient's back and the bed to help the patient maintain a side-lying or other specific lying position, preventing them from sliding back to a supine position and thus prolonging the time between pressure point changes.

[0003] Most turning pillows on the market are one-piece structures. These pillows are typically made of fixed-shape foam, memory foam, air bladders, or a single filling material. Their shape and support firmness are fixed after manufacturing, lacking effective adjustment capabilities. This one-piece structure can easily cause localized pressure discomfort or even injury. During use, especially when maintaining a side-lying position, the fixed shape of the pillow continuously and evenly presses against the entire back of the patient. This means that it inevitably applies pressure to areas of wound or pain on the patient's back. This pressure not only causes severe pain and discomfort, affecting rest quality and treatment adherence, but may also hinder wound healing, even aggravating existing injuries and creating new pressure sore risk points.

[0004] Therefore, a turning pillow with a turn-over function is needed. Utility Model Content

[0005] The purpose of this invention is to provide a turning pillow with a clearance function. By arraying multiple positioning holes on the support frame, a pad can be installed within these holes via a quick-release structure. When a patient using the turning pillow has a wound or pain on their back, the corresponding pad can be removed. This overcomes the shortcomings of existing turning pillows, which are one-piece structures and may apply pressure to wounds or pain points on the patient's back during use, causing severe pain and discomfort. The specific technical solution is as follows:

[0006] A turning pillow with a collision avoidance function includes a base plate, a support frame, and a pad. One edge of the base plate is connected to one edge of the support frame, and an angle is formed between the base plate and the support frame. The support frame has a plurality of positioning through holes arranged in an array. The positioning through holes are stepped holes, and the pad is installed in the positioning through holes through a quick-release structure.

[0007] Preferably, it also includes a telescopic rod and a hinge, the base plate and the support frame are rotatably connected, and the two ends of the telescopic rod are rotatably connected to the base plate and the support frame respectively through hinges.

[0008] Preferably, the telescopic rod includes a locking nut, a sleeve, and a movable rod. One end of the movable rod is installed inside the sleeve, and the sleeve and the movable rod are threaded together. The end of the movable rod away from the sleeve is rotatably connected to the support frame via a hinge. The end of the sleeve away from the movable rod is rotatably connected to the base plate via a hinge. The sleeve and the hinge are rotatably connected. The locking nut is installed on the movable rod.

[0009] Preferably, the quick-release structure includes a first magnet and a second magnet. The first magnet is installed on the countersunk surface of the positioning through hole, and the second magnet is installed on the pad. The magnetic fields of the first magnet and the second magnet are in opposite directions.

[0010] Preferably, the pad includes a positioning plate and a support plate. The positioning plate and the countersunk hole of the positioning through hole are nested together. The second magnet is mounted on the positioning plate. The support plate is mounted on the side of the positioning plate away from the second magnet. When the positioning plate is installed in the positioning through hole, the support plate is located outside the positioning through hole and the edges of the support plates are in contact with each other.

[0011] Preferably, a flexible component is fitted onto the outer wall of the support plate.

[0012] Preferably, the surface formed by the combination of the multiple support plates is an arc surface.

[0013] Preferably, a clearance unit is installed on the side of the support frame near the telescopic rod. The clearance unit includes a support column and a connecting plate. One end of the support column is vertically installed on the support frame and located between the positioning through holes. The other end of the support column is connected to the connecting plate. The end of the moving rod away from the sleeve is rotatably connected to the connecting plate through a hinge.

[0014] Preferably, the device also includes a positioning pad, a front headrest, and Velcro. The Velcro includes a rough side and a hook side. The rough side is installed on the positioning pad, and the hook side is installed on the bottom of the base plate and the bottom of the front headrest. The base plate and the front headrest are installed on the positioning pad by Velcro. The front headrest is located on the side near the connection between the base plate and the support frame, and is used to support the patient's chest.

[0015] Compared with existing technologies, this utility model has the following beneficial effects:

[0016] 1. This utility model provides a support frame with multiple positioning through holes arranged in an array. The pad is installed in the positioning through holes through a quick-release structure. When the patient uses this application to turn over or stay in a side-lying position, if there is a wound or pain point area on the patient's back, the pad at the corresponding position can be removed. This provides support for the patient's back while keeping the wound or pain point area in a non-contact state, avoiding causing the patient to experience severe pain and discomfort, and affecting the quality of rest and treatment compliance.

[0017] 2. This utility model employs a threaded adjustable telescopic rod, allowing for stepless adjustment of its length. This ensures the angle between the support frame and the base plate is appropriately sized, enabling the pad to better conform to the patient's back. After medical personnel adjust the length of the telescopic rod, a locking nut applies a reaction force, causing the moving rod to rub against the sleeve and lock in place, preventing loosening.

[0018] 3. This utility model, by mounting the base plate and front pillow onto the positioning pad, provides support for the patient's back with the pad and for the front pillow to support the patient's chest, abdomen, and legs, allowing the patient to better maintain a side-lying position and improving patient comfort. Furthermore, since the base plate and front pillow are secured to the positioning pad with Velcro, they can be adjusted to suit the patient's body shape, enhancing practicality.

[0025] 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.

[0026] Next, the working principle of this embodiment will be described in detail so that those skilled in the art can better understand this utility model:

[0027] A turning pillow with a clearance function includes a base plate 1, a support frame 2, and a pad 3. One edge of the base plate 1 is connected to one edge of the support frame 2, forming an angle between them. The support frame 2 has multiple positioning through holes 21 arranged in an array. These holes are stepped, and when they cooperate with the pad 3, they restrict the pad 3's horizontal movement along the plane of the support frame 2, while also providing support when the pad 3 is compressed. The pad 3 is installed within the positioning through holes 21 via a quick-release structure, allowing medical staff to quickly remove and install the pad 3, improving work efficiency. When a patient uses this pillow to turn over or remain in a side-lying position, if the patient has a wound or pain point on their back, the corresponding pad 3 can be removed, providing support to the patient's back while keeping the wound or pain point uncontacted. Prolonged contact with wounds or pain areas can cause intense pain and discomfort for patients, affecting their rest quality and treatment adherence. It may also hinder wound healing, worsen existing injuries, and create new pressure ulcer risk points. Therefore, this application can effectively avoid these situations.

[0028] Furthermore, the pad 3 can be designed as multiple pieces combined to form an arc surface, so that the pad 3 fits the physiological curve of the patient's back better and improves the patient's comfort.

[0029] Furthermore, the base plate 1 and the support frame 2 are rotatably connected, and both ends of the telescopic rod 4 are rotatably connected to the base plate 1 and the support frame 2 respectively via hinges 5. The telescopic rod 4 includes a locking nut 6, a sleeve 41, and a moving rod 42. One end of the moving rod 42 is installed inside the sleeve 41, and the sleeve 41 and the moving rod 42 are threadedly connected. The end of the moving rod 42 away from the sleeve 41 is rotatably connected to the support frame 2 via hinges 5, and the end of the sleeve 41 away from the moving rod 42 is rotatably connected to the base plate 1 via hinges 5. Since the sleeve 41 and the hinge 5 are rotatably connected, the sleeve 41 can rotate relative to the hinge 5, and the sleeve 41 can rotate around its own axis without causing the hinge to rotate synchronously. When medical staff need to adjust the length of the telescopic rod 4, they can do so by rotating the sleeve 41 to make it rotate around its own axis. Since the movable rod 42 is fixedly connected to the hinge 5, the movable rod 42 and the sleeve 41 will not rotate synchronously. The rotation of the sleeve 41 will drive the movable rod 42 to make linear displacement, thereby adjusting the angle between the support frame 2 and the base plate 1. The locking nut 6 is installed on the movable rod 42. After the medical staff has adjusted the length of the telescopic rod 4, the locking nut can be rotated and moved to abut against the sleeve 41. The locking nut applies a reaction force to make the movable rod 42 and the sleeve 41 rub against each other and lock, preventing loosening and improving the reliability of this application.

[0030] In another embodiment, the telescopic rod 4 can also employ a positioning hole and a spring pin. Multiple positioning holes are arrayed along the axis of the sleeve 41 to engage with the spring pin. The spring pin is installed on the movable rod 42, and the movable rod 42 and sleeve 41 are slidably connected. When the length of the telescopic rod 4 needs to be adjusted, medical personnel can press the spring pin into the positioning hole and then push the movable rod 42 to slide relative to the sleeve 41. When the spring pin moves to the coaxial position of the next positioning hole, it enters the positioning hole under the action of a spring, locking the movable rod 42 and sleeve 41. Compared to threaded adjustment, this embodiment offers faster adjustment speed and improves work efficiency, but it cannot achieve stepless adjustment. The choice should be made based on the actual situation.

[0031] The quick-release structure includes a first magnet and a second magnet. The first magnet is embedded in the countersunk surface of the positioning through-hole 21. The pad 3 includes a positioning plate 31 and a support plate 32. The positioning plate 31 is nested within the countersunk surface of the positioning through-hole 21, and the second magnet is embedded in the positioning plate 31. The support plate 32 is bolted to the side of the positioning plate 31 away from the second magnet. The magnetic fields of the first and second magnets are in opposite directions, thus creating an attraction between them. When the positioning plate 31 is installed inside the positioning through-hole 21, the support plate 32 is located outside the positioning through-hole 21, and the edges of the support plates 32 fit together, preventing gaps between the support plates 32 from squeezing the patient's back and causing discomfort. Simultaneously, since the pad 3 completely covers the support frame 2, the patient will not come into contact with the support frame 2, preventing contamination. When changing patients, only the pad 3 needs to be replaced, thus avoiding cross-infection between patients. However, since there is no gap between the pads 3, when it is necessary to remove the pads 3, medical staff can push the pads 3 through the positioning through hole 21 from the side of the support frame away from the pads 3 until the pads 3 overcome the magnetic attraction and separate from the support frame 2.

[0032] The outer wall of the support plate 32 is fitted with flexible components, such as a removable fabric cover, which provides a more skin-friendly contact for the patient. Furthermore, when the flexible components become contaminated or soiled, they can be replaced, avoiding the need to clean the pad 3, reducing workload and improving work efficiency.

[0033] To prevent the connection between hinge 5 and support frame 2 from interfering with medical staff pushing the pad 3 through the positioning through hole 21, an obstacle avoidance unit is installed on the side of support frame 2 near telescopic rod 4. This obstacle avoidance unit includes support column 7 and connecting plate 8. One end of support column 7 is vertically threaded onto support frame 2 and located between the positioning through holes 21. The other end of support column 7 is bolted to connecting plate 8. The end of moving rod 42 away from sleeve 41 is rotatably connected to connecting plate 8 via hinge 5. The space created between support column 7 and connecting plate 8 provides obstacle avoidance, preventing hinge 5 from interfering with medical staff.

[0034] To facilitate movement of the device and reduce its weight, the pad 3, base plate 1, support frame 2, telescopic rod 4, hinge 5, support column 7, and connecting plate 8 can all be made of low-density non-metallic materials, such as polymer materials or carbon fiber materials.

[0035] Furthermore, this application also includes a positioning pad 9, a front pillow 10, and Velcro. The Velcro includes a textured surface and a hooked surface. The textured surface is installed on both sides of the positioning pad 9 to avoid contact with the patient. The bottom of the base plate 1 and the bottom of the front pillow 10 are both equipped with hooked surfaces. The base plate 1 and the front pillow 10 are installed on the positioning pad 9 through the mating of the textured surface and the hooked surface. The front pillow 10 is located on the side near the connection between the base plate 1 and the support frame 2. The pad 3 supports the patient's back, and the front pillow 10 supports the patient's chest, abdomen, and legs, allowing the patient to better maintain a side-lying position while preventing lower limb friction, ensuring functional positioning, and improving patient comfort. At the same time, since the base plate 1 and the front pillow 10 are fixed to the positioning pad 9 by Velcro, the textured surface and the hooked surface only need partial contact to form a relatively stable connection. Therefore, the width or relative position between the two can be adjusted arbitrarily according to the patient's body shape, improving practicality. A flexible component is also fitted onto the front pillow 10. If the front pillow 10 is not needed, the front pillow 10 and the positioning pad 9 can be removed.

[0036] In summary, the usage procedure of this application is as follows: Place the turning pillow on the hospital bed according to the patient's position, rotate the sleeve 41 to adjust the length of the telescopic rod 4, and then lock and fix it with the locking nut 6. If the patient has a wound on his back, remove the pad 3 on the support frame 2 corresponding to the wound position, lift the patient's body, move the base plate 1, and let the patient's back rest on the pad 3 to complete the support for the patient.
