Description

Technical Field

[0001] This utility model relates to the field of nursing tools, specifically to a triangular turning pillow with a side telescopic bar. Background Technology

[0002] In medical and home care settings, turning over is a core need for long-term bedridden patients (such as postoperative recoveries, paralyzed patients, and elderly people with disabilities). These patients have limited independent mobility and need to rely on caregivers to assist them in turning over in order to prevent pressure sores, improve blood circulation, and reduce the risk of lung infections.

[0003] Currently, the main type of turning-over aid on the market is the ordinary triangular pillow, but it has obvious limitations in actual use, mainly in the following three aspects: Poor stability and easy displacement: Ordinary triangular pillows rely solely on their own weight to rest on the hospital bed. When patients turn over, the pressure of their bodies or unconscious movements can easily cause the pillow to shift or slip off. This is especially true for heavier patients, who require frequent adjustments by caregivers, increasing the burden of care.

[0004] Insufficient adaptability: Different models of hospital beds have different widths (such as standard hospital beds and widened nursing beds), while the size of traditional triangular pillows is fixed and cannot be adjusted according to the width of the hospital bed. They are difficult to stably fit the sides of the patient's body and affect the effect of turning over.

[0005] Limited support stability: Some triangular pillows are filled with ordinary sponge, which is prone to collapse after long-term use and cannot provide sufficient support continuously; at the same time, their outer fabric is mostly ordinary cotton cloth, which has weak abrasion resistance and antibacterial properties. Long-term contact with the patient's skin can easily breed bacteria and increase the risk of infection. Utility Model Content

[0006] The purpose of this invention is to provide a triangular turning pillow with a side telescopic bar, in order to solve the problem mentioned in the background art that ordinary triangular pillows rely solely on their own weight to be placed on the hospital bed. When patients turn over, the body pressure or unconscious movements can easily cause the pillow to shift or slip off. This is especially true for heavier patients, who require frequent adjustments by caregivers, increasing the burden of care.

[0007] To achieve the above objectives, this utility model provides a triangular turning pillow with side telescopic bars, including a triangular turning pillow body, two telescopic bar assemblies, and a bed rail connecting mechanism; the triangular turning pillow body has a triangular prism structure, its interior is filled with elastic support material, and its exterior is covered with breathable and wear-resistant fabric; the two telescopic bar assemblies are respectively symmetrically fixed at both ends of the triangular turning pillow body, and the extension direction of the telescopic bar assemblies is consistent with the length direction of the triangular turning pillow body; The bed railing connection mechanism is fixedly installed at one end of each telescopic bar assembly away from the main body of the triangular turning pillow, and is used for detachable connection with one side of the bed railing of the hospital bed; By adjusting the length of the telescopic bar assembly, it can be adapted to hospital beds of different widths. After the bed rail connecting mechanism is connected and fixed to the bed rail, it can limit the displacement of the triangular turning pillow body on the hospital bed, which is especially suitable for patients with larger body weight.

[0008] This setup utilizes a combination of a triangular turning pillow (1), two symmetrical telescopic bar components (2), and a bed rail connection mechanism (3) to construct a core functional system: the triangular columnar main body provides the support base needed for turning over, the internal elastic material ensures support, and the external fabric balances comfort and durability; the telescopic bar components extend along the length of the main body, and the distance between the main body and the bed rail can be adjusted by length adjustment; the bed rail connection mechanism detachably connects the telescopic bar to the bed rail, forming a fixed link of "main body - telescopic bar - bed rail", restricting the movement of the main body. Preferably, the telescopic bar assembly includes a fixed sleeve, a movable rod, and a locking element; the fixed sleeve has a cavity extending along its length; one end of the movable rod is slidably inserted into the cavity of the fixed sleeve, and the other end is hinged to the end of the triangular turning pillow body; the side wall of the fixed sleeve has a threaded hole communicating with the internal cavity, and the locking element is a bolt adapted to the threaded hole. After the bolt passes through the threaded hole, it abuts against the movable rod to fix the length of the telescopic bar assembly.

[0009] This setting adopts a “nested sliding + bolt locking” adjustment structure: the cavity inside the fixed sleeve (21) provides a sliding channel for the movable rod (22), which can extend and retract along the cavity to change the total length of the assembly; the threaded hole on the side wall of the fixed sleeve cooperates with the bolt (locking part 23), and after the bolt passes through the threaded hole, it presses against the surface of the movable rod, and fixes the position of the movable rod by friction, thereby locking the length of the telescopic rod.

[0010] Preferably, the outer surface of the movable rod is provided with a plurality of evenly distributed positioning grooves along the length direction, and the end of the locking member can be inserted into the positioning grooves to further enhance the stability of the telescopic rod assembly after the length is fixed.

[0011] This feature provides a uniformly distributed positioning groove (221) on the outer surface of the movable rod (22) along the length direction. When the length of the telescopic rod is adjusted, the bolt end of the locking member (23) can be inserted into the corresponding groove to form a mechanical interlocking structure of "bolt-groove", rather than simply relying on the friction between the bolt and the surface of the movable rod for fixation.

[0012] Preferably, the bed rail connecting mechanism includes a U-shaped clamp, an adjusting screw, and a clamping block; the opening of the U-shaped clamp faces one side of the bed rail, one side wall of which is fixedly connected to the telescopic bar assembly, and the other side wall is provided with a threaded through hole; the adjusting screw is adapted to the threaded through hole, one end of which extends into the U-shaped clamp and is rotatably connected to the clamping block, and the other end is provided with a knob; rotating the knob can drive the clamping block to move along the direction closer to or away from the other side wall of the U-shaped clamp, thereby achieving clamping and fixing of bed rails of different diameters.

[0013] This setup uses a "U-shaped clamp + screw adjustment" adapter structure: the U-shaped clamp (31) opens towards the bed railing and can initially fit railings of different diameters; the adjusting screw (32) engages with the threaded through hole on the side wall of the U-shaped clamp, and when the knob (321) is turned, the screw drives the clamping block (33) to move axially, and the railing is clamped and fixed by the relative compression between the clamping block and the inner wall of the U-shaped clamp.

[0014] Preferably, the clamping block has an anti-slip rubber pad on the side of its surface near the bed rail, and the surface of the anti-slip rubber pad has anti-slip texture to increase the friction between it and the bed rail and prevent the bed rail connecting mechanism from sliding on the bed rail.

[0015] This setting involves attaching an anti-slip rubber pad (331) to the side of the clamping block (33) near the bed rail, and setting anti-slip textures on the surface of the rubber pad: the rubber material itself has a high coefficient of friction, which can increase the static friction between the clamping block and the rail surface; the anti-slip textures further increase the roughness of the contact area, reducing the possibility of "the clamping block and the rail sliding relative to each other".

[0016] Preferably, the elastic support material of the main body of the triangular turning pillow is memory foam or high-elastic sponge, the breathable and wear-resistant fabric is a cotton-linen blend or polyester fiber fabric, and the surface of the fabric is provided with an antibacterial coating.

[0017] This setting allows you to select materials based on three dimensions: "support, comfort, and safety." Internal elastic support material (memory foam / high-elasticity sponge): Features slow rebound (memory foam) or high elasticity (high-elasticity sponge), adapting to the patient's body contours for support while maintaining good anti-collapse capabilities; External fabric (cotton-linen blend / polyester fiber): Cotton-linen blend combines breathability and skin-friendliness, while polyester fiber is wear-resistant and wrinkle-resistant; both fabrics meet long-term use requirements; Antibacterial coating on fabric surface: The coating inhibits the growth of bacteria (such as Escherichia coli and Staphylococcus aureus), reducing microbial adhesion.

[0018] Preferably, the main body of the triangular turning pillow is a triangular columnar structure with oblique support surfaces on both sides.

[0019] This design features a triangular columnar structure with slanted support surfaces on both sides (11): the triangular structure has geometric stability, which can prevent the main body from deforming during the support process; the slanted support surfaces are ergonomic, and can fit the arc contours of the patient's back, waist or legs respectively when turning over, forming "multi-point uniform support" rather than single-plane support.

[0020] Compared with the prior art, the beneficial effects of this utility model are as follows: This triangular turning pillow with a side telescopic bar completely solves the core problem of traditional triangular pillows easily shifting due to their reliance on weight alone, through a combination design of "telescopic bar assembly + bed rail connecting mechanism". The U-shaped clamp and adjusting screw in the bed rail connecting mechanism can securely clamp bed rails of different diameters. Combined with the anti-slip rubber pads and textured surfaces of the clamping blocks, this significantly increases friction with the bed rails, preventing the connecting mechanism from sliding. Simultaneously, the telescopic bar assembly, once fixed, provides rigid support for the main body of the triangular turning pillow, effectively limiting its movement on the bed even when facing the body pressure or unconscious movements of heavier patients turning over. This eliminates the need for frequent pillow adjustments by caregivers, significantly reducing workload and improving the efficiency and stability of turning care. The adjustable design of the telescopic bar assembly gives the product excellent adaptability, meeting the needs of beds of different widths (such as standard medical beds, widened nursing beds, and home care beds). By sliding the movable rod within the fixed sleeve, the overall length of the telescopic bar assembly can be flexibly adjusted, thereby changing the distance between the main body of the triangular turning pillow and the bed rails. This ensures that the pillow body accurately conforms to both sides of the patient's body, always in the optimal position for turning over. Compared to traditional fixed-size triangular pillows, this product does not require customization based on bed width and can be used in various nursing scenarios. This not only reduces equipment procurement costs for medical and home care but also enhances the product's practicality and accessibility. In terms of the material and structural design of the triangular turning pillow, multi-dimensional optimization has achieved a dual improvement in support stability and durability. The internal filling, memory foam or high-elasticity sponge, has excellent elastic recovery performance and support, and is not prone to collapse or deformation after long-term use, continuously providing stable support for patients to turn over, avoiding poor turning effect or patient discomfort due to insufficient support. The outer cotton-linen blend fabric or polyester fiber fabric combines breathability and abrasion resistance, effectively resisting friction wear during daily use and extending the fabric's lifespan. At the same time, the breathability reduces the stuffiness of the area where the patient's skin contacts the pillow, improving comfort. In addition, the antibacterial coating on the fabric surface inhibits bacterial growth, reducing the risk of infection caused by skin contact with the pillow for long-term bedridden patients, further ensuring the safety of care.

[0022] 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.

[0023] This utility model provides a triangular turning pillow with a side telescopic bar, such as Figures 1-4 As shown, the device includes a triangular turning pillow body 1, two telescopic bar assemblies 2, and a bed rail connecting mechanism 3. The triangular turning pillow body 1 has a triangular prism structure, which is filled with elastic support material and covered with breathable and wear-resistant fabric. The two telescopic bar assemblies 2 are symmetrically fixed at both ends of the triangular turning pillow body 1, and the extension direction of the telescopic bar assemblies 2 is consistent with the length direction of the triangular turning pillow body 1. The bed railing connection mechanism 3 is fixedly installed at one end of each telescopic bar assembly 2 away from the triangular turning pillow body 1, for detachable connection with one side of the bed railing of the hospital bed; By adjusting the length of the telescopic bar assembly 2, it can be adapted to hospital beds of different widths. After the bed rail connecting mechanism 3 is connected and fixed to the bed rail, it can limit the displacement of the triangular turning pillow body 1 on the hospital bed, which is especially suitable for patients with larger body weight.

[0024] The core functional system is constructed through a combination of "triangular turning pillow body 1 + two symmetrical telescopic bar assemblies 2 + bed rail connecting mechanism 3": the triangular columnar turning pillow body 1 provides the support base required for turning over, its internal elastic support material ensures support force, and the external breathable and wear-resistant fabric takes into account both comfort and durability; the telescopic bar assembly 2 extends along the length of the triangular turning pillow body 1, and the distance between the triangular turning pillow body 1 and the bed rail can be changed by adjusting the length; the bed rail connecting mechanism 3 detachably connects the telescopic bar assembly 2 to the bed rail, forming a fixed link of "triangular turning pillow body 1 - telescopic bar assembly 2 - bed rail", which restricts the displacement of the triangular turning pillow body 1. Solving the core problems of traditional triangular pillows being "unfixed and prone to displacement": Through the rigid connection between the bed rail connecting mechanism 3 and the bed rail, even if a heavier patient applies pressure to the main body 1 of the triangular turning pillow when turning over, it can prevent the pillow from slipping, reducing the frequency of adjustments by caregivers; Achieving bed width adaptability: There is no need to replace the main body 1 of the triangular turning pillow; simply adjusting the length of the telescopic bar assembly 2 can adapt to beds of different widths (such as standard beds and widened beds), improving the product's versatility; Laying the foundation for overall functionality: It provides structural support for subsequent detailed optimization of the telescopic bar assembly 2 and the bed rail connecting mechanism 3, ensuring that all components work together to achieve the turning assistance function.

[0025] In this embodiment, the telescopic bar assembly 2 includes a fixed sleeve 21, a movable rod 22, and a locking member 23. The fixed sleeve 21 has a cavity extending along its length. One end of the movable rod 22 is slidably inserted into the cavity of the fixed sleeve 21, and the other end is hinged to the end of the triangular turning pillow body 1. The side wall of the fixed sleeve 21 has a threaded hole communicating with the internal cavity. The locking member 23 is a bolt adapted to the threaded hole. After the bolt passes through the threaded hole, it abuts against the movable rod 22 to fix the length of the telescopic bar assembly 2.

[0026] The adjustment structure adopts "nested sliding + bolt locking": the internal cavity of the fixed sleeve 21 provides a sliding channel for the movable rod 22, which can extend and retract along the cavity to change the total length of the telescopic rod assembly 2; the threaded hole on the side wall of the fixed sleeve 21 cooperates with the bolt (locking member 23), and after the bolt passes through the threaded hole, it abuts against the surface of the movable rod 22, fixing the position of the movable rod 22 by friction, thereby locking the length of the telescopic rod assembly 2. Achieve precise length adjustment of telescopic bar assembly 2: The sliding design can flexibly adapt to different bed widths, and the adjustment process is simple and requires no professional tools; Ensure reliable length fixation: The bolt (locking part 23) anti-locking can withstand a certain external force (such as the pressure of the patient turning over), preventing the movable bar 22 from sliding on its own during use, and ensuring the stability of the triangular turning pillow body 1; Simple structure and easy maintenance: The telescopic bar assembly 2 has no complex transmission parts, making installation, disassembly and daily maintenance convenient, reducing the cost of use and maintenance.

[0027] Specifically, the outer surface of the movable rod 22 is provided with multiple evenly distributed positioning grooves 221 along the length direction, and the end of the locking member 23 can be inserted into the positioning grooves 221 to further enhance the stability of the telescopic rod assembly 2 after the length is fixed.

[0028] Evenly distributed positioning grooves 221 are provided on the outer surface of the movable rod 22 along the length direction. When the length of the telescopic rod assembly 2 is adjusted, the bolt end of the locking member 23 can be inserted into the corresponding positioning groove 221 to form a mechanical interlocking structure of "bolt (locking member 23) - positioning groove 221", rather than simply relying on the friction between the bolt and the surface of the movable rod 22 for fixation. Significantly improves the stability of the telescopic bar assembly 2: The mechanical interlocking avoids the problem of "loose bolts (locking parts 23) causing the movable rod 22 to slide" when fixed by simple friction. Even with long-term use or under large external forces, the length of the telescopic bar assembly 2 can still remain stable. Auxiliary length positioning: The evenly distributed positioning grooves 221 can be used as "gradations" to facilitate nursing staff to quickly adjust the telescopic bar assembly 2 to the required length and improve operating efficiency.

[0029] Furthermore, the bed rail connection mechanism 3 includes a U-shaped clamp 31, an adjusting screw 32, and a clamping block 33; the opening of the U-shaped clamp 31 faces one side of the bed rail, one side wall of which is fixedly connected to the telescopic bar assembly 2, and the other side wall is provided with a threaded through hole; the adjusting screw 32 is adapted to the threaded through hole, one end of which extends into the U-shaped clamp 31 and is rotatably connected to the clamping block 33, and the other end is provided with a knob 321; rotating the knob 321 can drive the clamping block 33 to move in the direction close to or away from the other side wall of the U-shaped clamp 31, thereby realizing the clamping and fixing of bed rails of different diameters.

[0030] The system employs a "U-shaped clamp + screw adjustment" adaptation structure: the U-shaped clamp 31 has its opening facing the bed rail, allowing for initial fitting of rails of different diameters; the adjusting screw 32 engages with the threaded through hole on the side wall of the U-shaped clamp 31, and when the knob 321 is turned, the adjusting screw 32 drives the clamping block 33 to move axially, achieving clamping and fixing of the rail through the relative compression between the clamping block 33 and the inner wall of the U-shaped clamp 31. Adaptable to bed rails of different diameters: No need to replace the bed rail connecting mechanism 3, it can be adapted to different specifications of rails commonly found in hospitals and homes (such as round and oval rails) by adjusting the screw 32, expanding the product's applicable scenarios; Detachable and reliably fixed: The knob 321 adjustment is simple to operate, and it can provide sufficient clamping force after clamping to prevent the bed rail connecting mechanism 3 from falling off the rail during use. At the same time, when disassembling, only the knob 321 needs to be turned in the opposite direction, which makes it easy to move or store the triangular turning pillow body 1.

[0031] Furthermore, the clamping block 33 has an anti-slip rubber pad 331 on the side surface near the bed rail. The surface of the anti-slip rubber pad 331 has anti-slip texture to increase the friction between it and the bed rail and prevent the bed rail connecting mechanism 3 from sliding on the bed rail.

[0032] An anti-slip rubber pad 331 is attached to the side of the clamping block 33 near the bed rail, and anti-slip textures are provided on the surface of the anti-slip rubber pad 331. The rubber material of the anti-slip rubber pad 331 itself has a high coefficient of friction, which can increase the static friction between the clamping block 33 and the surface of the rail. The anti-slip textures on the surface of the anti-slip rubber pad 331 further increase the roughness of the contact area, reducing the possibility of "relative sliding between the clamping block 33 and the rail". Eliminate the risk of slippage in the bed rail connection mechanism 3: Even if the bed rail surface is smooth (such as metal railings), or the patient applies lateral pulling force to the triangular turning pillow body 1 when turning over, the anti-slip rubber pad 331 can still firmly adhere to the railing, preventing the bed rail connection mechanism 3 from sliding up and down or left and right along the railing; Protect the bed railing: The anti-slip rubber pad 331 is soft in texture, and when clamped, it can avoid scratch damage caused by direct contact between the metal clamping block 33 and the railing, thus extending the service life of the hospital bed.

[0033] Furthermore, the elastic support material of the main body 1 of the triangular turning pillow is memory foam or high-elastic sponge, and the breathable and wear-resistant fabric is cotton-linen blend or polyester fiber fabric, and the surface of the fabric is coated with an antibacterial coating.

[0034] The material for the main body of the triangular turning pillow was selected based on three dimensions: support, comfort, and safety. Internal elastic support material (memory foam / high-elasticity sponge): It has slow rebound (memory foam) or high elasticity (high-elasticity sponge) characteristics, which can adapt to the patient's body contour to support the main body of the triangular turning pillow 1, while also having good anti-collapse ability; External fabric (cotton and linen blend / polyester fiber): The cotton and linen blend combines breathability and skin-friendliness, while the polyester fiber is wear-resistant and wrinkle-resistant. Both fabrics can meet the long-term use needs of the main body of the triangular turning pillow 1; Antibacterial coating on the fabric surface: The coating inhibits the growth of bacteria (such as Escherichia coli and Staphylococcus aureus) and reduces the adhesion of microorganisms on the surface of the main body of the triangular turning pillow 1. Enhanced support and comfort: Memory foam / high-elasticity sponge provides stable support for the main body of the triangular turning pillow 1, avoiding the problem of traditional sponge "collapse leading to support failure," while conforming to the body's curves to reduce local pressure; breathable fabric wicks away sweat, preventing stuffiness and dampness in the area where the skin contacts the main body of the triangular turning pillow 1; Ensuring safety and durability: Antibacterial coating reduces the risk of skin infection for long-term bedridden patients (especially suitable for elderly and postoperative patients with weakened immunity); abrasion-resistant fabric reduces external damage to the main body of the triangular turning pillow 1 caused by daily friction, extending the overall lifespan of the pillow.

[0035] Furthermore, the main body 1 of the triangular turning pillow is a triangular columnar structure with oblique support surfaces 11 on both sides.

[0036] The main body 1 of the triangular turning pillow is designed as a triangular columnar structure with oblique support surfaces 11 on both sides: the triangular structure has geometric stability and can prevent the main body 1 of the triangular turning pillow from deforming during the support process; the oblique support surfaces 11 are ergonomic and can fit the arc contours of the patient's back, waist or legs respectively when turning over, forming "multi-point uniform support" rather than a single plane supporting the main body 1 of the triangular turning pillow. Optimized turning support effect: The slanted support surface 11 can better support the patient's body weight and avoid the problem of "body tilting and pressure concentration" caused by the poor fit between the support surface of the triangular turning pillow body 1 and the body when turning over; Adaptable to multiple turning postures: The two slanted support surfaces 11 can be used for "left turning" and "right turning" scenarios respectively. Caregivers can switch the support direction without flipping the triangular turning pillow body 1, improving the convenience of operation.

[0037] The following are the steps for using the triangular turning pillow with a side telescopic bar of this utility model: (I) Phase 1: Equipment preparation and initial inspection Component inspection: Confirm that the main body 1 of the triangular turning pillow has no fabric damage and the elastic support material has not collapsed; the fixed sleeve 21 and movable rod 22 of the telescopic bar assembly 2 slide smoothly and the locking part 23 (bolt) is free of rust; the U-shaped clamp 31, adjusting screw 32, clamping block 33 and anti-slip rubber pad 331 of the bed rail connecting mechanism 3 are intact and the knob 321 rotates flexibly. Scene confirmation: Determine the width of the bed and the diameter of the bed rails, and plan the placement of the triangular turning pillow body 1 (usually on one side of the patient's body, such as the area corresponding to the back or waist) to ensure that it can accurately assist in turning over after installation. (II) Phase 2: Extension and Adjustment and Bed Adaptation Telescopic bar length adjustment: Loosen the locking piece 23 of the telescopic bar assembly 2 (turn the bolt counterclockwise) so that the movable rod 22 can slide freely in the cavity of the fixed sleeve 21; Depending on the width of the hospital bed, push the main body 1 of the triangular turning pillow to move the movable rod 22 along the length of the fixed sleeve 21, and adjust the distance between the main body 1 of the pillow and the bed rail: if the hospital bed is wide, pull the movable rod 22 outward to extend the total length of the telescopic bar; if the hospital bed is narrow, push the movable rod 22 inward to shorten the length. When the pillow body 1 reaches the target position (such as close to the back area when the patient is lying on their side), observe the positioning groove 221 of the movable rod 22, align the threaded hole on the side wall of the fixing sleeve 21 with a certain groove, tighten the locking piece 23 clockwise until the end of the bolt is inserted into the positioning groove 221, forming a mechanical engagement, locking the length of the telescopic rod assembly 2, and preventing slippage during use. Bed rail connection and fixing: Align the opening of the U-shaped clamp 31 of the bed rail connecting mechanism 3 with the bed rail on one side of the hospital bed, and fit the rail until the inner wall of the U-shaped clamp 31 fits against the surface of the rail; Turn the knob 321 of the adjusting screw 32 clockwise to drive the clamping block 33 to move axially toward the railing: as the knob turns, the clamping block 33 and the inner wall of the U-shaped clamp 31 gradually press against the railing until the anti-slip rubber pad 331 is completely in contact with the surface of the railing and the overall connection mechanism is not loose. Check the fixation effect: Gently pull the main body 1 of the triangular turning pillow to confirm that the bed rail connection mechanism 3 does not slide and the telescopic bar assembly 2 does not shift, ensuring that the overall structure is stably connected to the hospital bed. (III) Stage 3: Turning over assistance and posture maintenance Assisted operation for turning over: Nursing staff assist the patient to lie on their side (such as turning to the left), and place one side of the triangular turning pillow body 1 with the oblique support surface 11 against the curve of the patient's back: because the body 1 is filled with memory foam or high-elastic sponge, it will adapt to the patient's body contour and form multi-point uniform support. Adjust the position of the pillow body 1 to ensure that its top fits the patient's shoulder and its bottom supports the lower back, preventing the patient from tilting to the supine position due to muscle weakness or unconscious movement; at this time, the fixed link formed by the telescopic bar assembly 2 and the bed rail connection mechanism 3 can resist the lateral pressure of the patient's body on the pillow body 1 and prevent the pillow from shifting. Posture maintenance and nursing monitoring: The triangular columnar structure of the main body 1 of the triangular turning pillow has geometric stability. Combined with the resilience of the elastic material, it can maintain the patient's side-lying position for a long time and reduce the frequency of adjustment by caregivers. Breathable and durable fabrics and antibacterial coatings work together: the fabrics wick away sweat from the area where the patient's skin contacts the pillow, preventing stuffiness and dampness; the antibacterial coatings inhibit bacterial growth, reducing the risk of skin infections for patients who are bedridden for extended periods. If it is necessary to change the direction of turning over (such as turning from the left to the right), there is no need to disassemble the entire structure. Simply turn the patient's body to the other side and place the other side of the pillow body 1, the oblique support surface 11, against the patient's back to complete the posture change. The operation is convenient. (iv) Phase 4: Post-use storage and disassembly Unlock the connection mechanism: Turn the knob 321 of the bed rail connection mechanism 3 counterclockwise to move the clamping block 33 away from the bed rail until the U-shaped clamp 31 can be removed from the rail; Retracting the telescopic bar: Loosen the locking piece 23 of the telescopic bar assembly 2, push the movable rod 22 completely into the fixed sleeve 21, shorten the total length of the telescopic bar, and reduce the storage space; Cleaning and storage: If the fabric of the main body 1 of the triangular turning pillow is removable, it can be removed and washed; if it is not removable, wipe the surface dust and stains with a damp cloth; store the entire device in a dry and ventilated place to avoid the elastic material from getting damp and moldy or the metal components from rusting.
