Technical Field
[0001] This utility model relates to the field of medical assistive device technology, specifically to a patient bed position adjustment cushion. Background Technology
[0002] When patients are bedridden, scientifically changing their body posture and position can prevent complications, improve comfort, and promote recovery. Patients often need to use cushions for support during prolonged bed rest. To improve the effectiveness of these cushions, existing technologies have proposed adjustable ones. For example, Chinese patent document CN204581792U discloses an adjustable positioning cushion. This cushion features a tiltable top plate on its base, is foldable for easy operation and portability, and allows for accurate positioning at various angles. This ensures that patients who are bedridden, paralyzed, or unable to care for themselves can maintain a precise position during meals, nasogastric feeding, and other bed exercises, guaranteeing a standard positioning at multiple angles.
[0003] However, the aforementioned cushion can only be adjusted at a fixed angle by inserting a clip between the top plate and a fixed position. Since the number of clips is fixed, the cushion can only be adjusted at a fixed angle and cannot be adjusted to multiple angles independently according to different treatment needs, which reduces the effectiveness of the cushion. Summary of the Invention
[0004] To address the aforementioned shortcomings of existing technologies, this invention proposes a patient bed-positioning adjustable cushion, comprising a base box and a cover fitted onto the top of the base box. A crossbar is fixed to one end of the base box, and the cover is rotatably fitted onto the crossbar. A support rod is fixed to the end of the cover away from the crossbar. Sliding grooves are formed on both sides of the base box, and a pulley is slidably mounted in each groove. A fixing rod is fixed to the outer end wall of the pulley. An adjusting plate is rotatably fitted onto the walls of the support rod and the fixing rod. A first through hole and a second through hole, respectively, are formed at both ends of the adjusting plate, which are adapted to the support rod and the fixing rod. Multiple slots are formed on the wall of the first through hole. A sliding hole is formed radially on the circumference of the support rod connected to the first through hole, and an elastic component, including a locking rod and an inner rod, passes through the sliding hole. This invention, through the interlocking and cooperation between multiple locking rods and slots, can adjust the rotational support angle of the cushion in multiple stages, adapting to various treatment needs and improving the cushion's performance.

[0028] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.
[0029] This utility model discloses a patient bed position adjustment cushion.
[0030] This utility model provides, for example Figure 1-6 This invention relates to a patient bed rest position adjustment cushion, comprising a base box 1 and a cushion cover 2 fitted onto the top of the base box 1. The cushion cover 2 fits and cooperates with the base box 1 to form a closed structure, protecting the internal adjustment mechanism. The base 1 serves as the base of the cushion, providing stable support, and cooperates with the cushion cover 2 to form a rotatable support structure, ensuring the overall stability of the cushion. A crossbar 4 is fixedly provided at one end of the base box 1, and the cushion cover 2 is rotatably fitted onto the crossbar 4. Specifically, the two sides of the cushion cover 2 are respectively rotatably fitted onto the two ends of the crossbar 4 extending from the base box 1, serving as the rotation axis of the cushion cover 2, allowing the cushion cover 2 to rotate around the crossbar 4. The cushion cover 2 serves as the main support surface of the cushion, and by rotating, the tilt angle can be adjusted to adapt to different patient position needs. It also provides a fulcrum for rotation, realizing the angle adjustment function of the cushion cover 2.
[0031] A support rod 5 is fixedly installed at the end of the pad cover 2 away from the crossbar 4. Slide grooves 6 are provided on both sides of the base box 1 to guide the displacement direction of the pad cover 2 during rotation. A pulley 7 slides within each slide groove 6, providing a sliding track for the pulley 7. The guiding design of the slide grooves 6 and pulleys 7 ensures smooth and seamless angle adjustment, preventing wobbling. Figure 4 As shown, pulley 7 is an I-beam pulley. The rolling friction of pulley 7 reduces adjustment resistance, making angle adjustment easier. A fixed rod 8 is fixedly installed on the outer end wall of pulley 7. The support rod 5 and the fixed rod 8 together rotate to fit an adjusting plate 9. The fixed rod 8 and the support rod 5 together support the adjusting plate 9, ensuring stability during rotation. The two ends of the adjusting plate 9 have a first through hole and a second through hole respectively, which are used to accommodate the support rod 5 and the fixed rod 8. Specifically, the adjusting plate 9 is rotatably connected to the support rod 5 through the first through hole at the upper end, and is rotatably connected to the fixed rod 8 through the second through hole at the lower end. The adjusting plates 9 located on the left and right sides of the base box 1 are symmetrically arranged and have the same structure.
[0032] Multiple slots 10 are provided on the wall of the first through hole where the adjusting plate 9 is rotatably connected to the support rod 5. The multiple slots 10 are evenly distributed on the circumference of the first through hole. For details, please refer to [reference needed]. Figure 3 As shown, each slot 10 opens towards the first through hole and is connected to the first through hole. A sliding hole is radially formed on the circumference of the support rod 5 connected to the first through hole. Sliding holes are also formed at the points where the support rod 5 connects to the adjusting plate 9 on both the left and right ends, with two sliding holes symmetrically arranged. The middle of the sliding hole intersects the axis of the support rod 5, and the length of the sliding hole is equal to the diameter of the support rod 5. Both ends of the sliding hole penetrate the circumferential surface of the support rod 5.
[0033] An elastic component is installed inside the sliding hole, such as... Figure 5 As shown, the elastic component includes a locking rod 11, an inner rod 12, and a spring 13. One end of the inner rod 12 is fixedly connected to the end of the locking rod 11, or the two are integrally formed. The spring 13 is sleeved on the inner rod 12. The locking rod 11 is slidably inserted into the sliding hole. The end of the locking rod 11 away from the inner rod 12 can extend out of the sliding hole and be inserted into a slot 10 opened on the adjusting plate 9.
[0034] When the locking rod 11 is inserted into the sliding hole, a portion of the inner rod 12 near the locking rod 11 is also located inside the sliding hole, while a portion of the inner rod 12 away from the locking rod 11 extends out of the sliding hole. One end of the spring 13 is fixedly connected to the circumference of the support rod 5, and the other end of the spring 13 is fixedly connected to the inner rod 12. Under normal conditions, the spring 13 is in a contracted state, and the elastic force of the spring 13 can pull the inner rod 12 into the sliding hole, so that the end of the locking rod 11 away from the inner rod 12 can extend out of the sliding hole and be inserted into a slot 10 opened on the wall of the first through hole.
[0035] Grooves are also provided on both ends of the support rod 5. The inner end of the groove is connected to the sliding hole, and the outer end of the groove penetrates the end wall of the support rod 5. The length of the groove is less than the length of the sliding hole, that is, at least one end of the groove does not penetrate the circumferential surface of the support rod 5. Specifically, as shown in the figure... Figure 3 As shown.
[0036] like Figure 6 As shown, a connecting rod 14 is fixedly connected to the wall of each locking rod 11. The axis of the connecting rod 14 is perpendicular to the axis of the locking rod 11, that is, the connecting rod 14 is parallel to the support rod 5. The inner end of the connecting rod 14 passes through the groove and extends into the sliding hole and is fixedly connected to the locking rod 11. The outer end of the connecting rod 14 extends out of the groove and is fixedly connected to a handle 15. The handle 15 is U-shaped, and the ends of the two connecting rods 14 that are far apart are fixedly connected to the two ends of the handle 15 respectively. The locking rod 11 is connected to the handle 15 through the connecting rod 14. Pulling the handle 15 can drive the connecting rod 14 to slide up and down in the groove, thereby driving the locking rod 11 fixedly connected to the connecting rod 14 to slide up and down in the sliding hole, so that the end of the locking rod 11 that is far away from the inner rod 12 can extend out of the sliding hole and be inserted into the slot 10 opened on the adjusting plate 9, or be withdrawn from the slot 10.
[0037] That is, pulling the handle 15 can disengage the locking rod 11 from the slot 10, unlocking and adjusting the angle. The handle 15 provides a labor-saving grip point, making it easy for medical staff or patients to operate. Through the "pulley-adjusting plate-slot" structure, the tilt angle of the cushion can be adjusted in multiple levels to meet the needs of various treatment positions such as nasogastric feeding, breathing training, and postoperative recovery. When it is necessary to connect the locking rod 11 with the slot 10, the handle 15 can be pulled. When the connecting rod 14 is pushed towards the end near the spring 13, the connecting rod 14 drives the inner rod 12 to move synchronously and slide inside the support rod 5. At this time, the spring 13 is stretched. With the continuous pushing of the connecting rod 14, the end of the locking rod 11 slowly disengages from the slot 10. When the locking rod 11 is completely separated from the slot 10, the adjusting plate 9 can be rotated, causing the multiple slots 10 on the upper end of the adjusting plate 9 to be misaligned with the locking rod 11. When the support angle of the adjusting plate 9 is adjusted... After adjustment, release connecting rod 14. Under the elastic force of spring 13, inner rod 12 drives locking rod 14 to quickly rebound and insert the outer end of locking rod 11 into another slot 10, thus completing the connection between support rod 5 and adjusting plate 9 again. One end of connecting rod 14 is fixed to the wall of locking rod 11, and the other end protrudes from the groove. Both connecting rods 14 are fixed to handle 15. Through handle 15, both connecting rods 14 can be pulled simultaneously, causing both locking rods 11 to move simultaneously, facilitating synchronous adjustment of the two adjusting plates 9. The elastic component design allows locking rod 11 to automatically reset and lock, making operation convenient. Support rod 5 supports adjusting plate 9 and provides the mounting base for locking rod 11. Locking rod 11 can be inserted into slot 10. Adjusting plate 9 is sleeved on support rod 5 and fixing rod 8. The multi-slot design of slot 10 supports multi-angle adjustment, such as 30°, 45°, 60°, etc., to adapt to different treatment needs, such as semi-recumbent position, sitting position, etc.
[0038] In order to provide patients with comfortable and stable support, such as Figure 1-2 and Figure 5 As shown, a pressure-relief sponge 3 is fixedly installed on the top of the cushion cover 2. The upper end of the pressure-relief sponge 3 is arc-shaped and wraps around the outer side of the upper end of the cushion cover 2. It is fixed to the top of the cushion cover 2. The arc-shaped design conforms to the curve of the back or legs of the human body. The elastic cushioning effect of the sponge reduces the pressure on the patient's pressure points and improves comfort. A connecting silicone pad 16 is fixedly installed at the lower end of the cushion cover 2. The connecting silicone pad 16 is set in conjunction with the pressure-relief sponge 3 and is located at the lower end of the cushion cover 2. Together with the pressure-relief sponge 3, it forms a continuous supporting arc surface. The anti-slip properties of the silicone pad enhance the friction between the cushion and the bed surface and prevent slippage. The arc-shaped support structure of the pressure-relief sponge 3 and the connecting silicone pad 16, combined with the elastic cushioning design, reduces the pressure points on the patient's body and avoids the discomfort of traditional hard cushions.
[0039] Working principle: When adjusting the angle, pull the handle 15, which drives the locking rod 11 to retract inward against the elastic force of the spring 13 through the connecting rod 14, so that the locking rod 11 disengages from the locking groove 10 of the adjusting plate 9. At this time, the pad cover 2 can rotate around the crossbar 4, and at the same time, the pulley 7 slides synchronously in the sliding groove 6 of the bottom box 1, driving the fixed rod 8 to move along the sliding groove 6, so that the adjusting plate 9 rotates around the support rod 5 and the fixed rod 8 as the axis, changing the tilt angle of the pad cover 2.
[0040] After adjusting to the appropriate angle, release the handle 15. The spring 13 returns to its original position and pushes the inner rod 12 and the locking rod 11 outward. The locking rod 11 is inserted into the corresponding slot 10 and locked, thus achieving multi-level fixation of the cushion's support angle.
[0041] The pressure sponge 3 and the connecting silicone pad 16 form an arc-shaped buffer structure that fits the patient's back or legs, providing stable and comfortable support. At the same time, the base box 1 is rotatably connected to the pad cover 2 via the crossbar 4, and combined with the sliding guide of the pulley 7, it ensures that the angle adjustment process is smooth and the support structure is stable.
[0042] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
