Description

An adjustable nursing bed board Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to an adjustable nursing bed board. Background Technology

[0002] In the clinical medical field, position-adjustable nursing beds, as key equipment supporting patient treatment, play an indispensable role in many important scenarios such as surgery, intensive care, and rehabilitation. During surgery, precise position control is crucial for the exposure of the surgical field, the convenience of surgical procedures, and patient comfort. In intensive care, appropriate positioning helps maintain stable vital signs and reduce the occurrence of complications. In the rehabilitation stage, scientific and reasonable position adjustment can promote the recovery of patients' physical functions and improve rehabilitation outcomes.

[0003] However, traditional position-adjustable nursing beds currently used in clinical practice have significant limitations in their position adjustment functions. Traditional jacks, as a crucial component for position adjustment, typically employ a fixed-point support design. This fixed-point support structure prevents the jack from dynamically adjusting its application point. In practical applications, this deficiency directly leads to a severe limitation on the range of positional angle adjustment. For example, when significant changes in patient position are required to meet specific treatment needs, traditional nursing beds often struggle to achieve this, thus impacting the effectiveness and efficiency of treatment.

[0004] Furthermore, patient safety and ease of use are also significant challenges with traditional nursing beds. Ensuring patient stability and preventing accidental injuries during repositioning is a key concern for healthcare professionals. Simultaneously, ease of use directly impacts the efficiency of healthcare workers and the patient's treatment experience. Traditional nursing beds often fall short in these aspects, failing to fully meet the diverse needs of clinical care. Summary of the Invention

[0005] To overcome at least one of the defects described in the prior art, this utility model provides an adjustable nursing bed board. This solves the problem of limited adjustment range of the body position angle in traditional nursing beds.

[0006] The technical solution adopted by this utility model to solve its problem is:

[0007] An adjustable nursing bed board includes: a bed board system, the bottom surface of which is provided with a sliding rail arranged along its length; a fitted sheet assembly, which is detachably mounted on the top surface of the bed board system; a jack, the top of which is provided with a pulley mechanism that slides within the sliding rail; and a sliding positioning system, which is used to limit the position of the pulley mechanism within the sliding rail.

[0008] By employing the above-described scheme, the jack can be dynamically adjusted along the length of the bed board by sliding the pulley mechanism within the sliding rail. This innovative design greatly expands the range of adjustment for the patient's position, allowing medical staff to flexibly adjust the patient's position according to their specific treatment needs, thereby improving treatment effectiveness and efficiency. Simultaneously, the sliding positioning system ensures the stability of the jack after it has been adjusted to the appropriate position.

[0009] Furthermore, the bed board system comprises, from top to bottom: a high-density sponge layer, the top surface of which is provided with an assembly part for assembly with the fitted sheet assembly; and a steel plate layer, with the sliding rail disposed on the bottom side of the steel plate layer.

[0010] By adopting the above solution, an assembly section is provided on the top surface of the high-density foam layer, specifically designed for assembly with the fitted sheet assembly. This design ensures the fitted sheet assembly is securely and stably fixed to the high-density foam layer, guaranteeing the flatness and stability of the fitted sheet and preventing displacement or wrinkling during use. The steel plate layer, serving as the support layer of the bed board system, possesses high strength and rigidity, capable of withstanding the patient's body weight and various forces generated during position adjustment. A sliding rail is located on the bottom side of the steel plate layer, providing a stable and reliable sliding track for the jack's pulley mechanism. The jack slides within the sliding rail via the pulley mechanism, enabling dynamic adjustment of the force application position along the length of the bed board, thereby expanding the range of positional angle adjustment and meeting the precise adjustment needs of patient position in different treatment scenarios.

[0011] Furthermore, the sliding rail includes a head sliding rail, a torso sliding rail, and a lower limb sliding rail connected end to end in sequence. When the head sliding rail, torso sliding rail, and lower limb sliding rail are collinear, the pulley mechanism can slide along the head sliding rail, torso sliding rail, and lower limb sliding rail. The steel plate layer includes a head plate, a torso plate, and a lower limb plate. The head sliding rail is located below the head plate, the torso sliding rail is located below the torso plate, and the lower limb sliding rail is located below the lower limb plate.

[0012] By adopting the above scheme, the segmented sliding rail design allows the jack to be independently adjusted for the head, torso, and lower limbs. At the same time, this design also facilitates personalized adjustments based on the patient's specific situation. For example, for patients with special needs in certain parts of the body, the comfort of the patient can be improved by adjusting the thickness of the sponge layer or the steel plate layer structure of the corresponding part.

[0013] Furthermore, the fitted sheet assembly comprises, from top to bottom: a surface layer, the surface of which is provided with a matrix of silicone particles; a middle layer, the middle layer comprising memory foam and temperature regulating gel; and a waterproof bottom layer, the bottom surface of which is provided with a fixing part for assembly with the bed board system.

[0014] By employing the above-mentioned design, the surface layer is incorporating a matrix of silicone particles. These particles possess excellent frictional properties, effectively increasing the coefficient of friction between the fitted sheet and the patient's body, thus preventing patient displacement during repositioning. The middle layer includes memory foam, which features slow rebound properties and adaptively deforms to conform to the patient's body curves, evenly distributing body pressure across the entire fitted sheet surface and reducing the risk of pressure sores. The temperature-regulating gel has heat absorption and dissipation functions, automatically adjusting the fitted sheet's temperature based on ambient and patient body temperatures. The impermeable bottom layer is made of a special impermeable material, effectively preventing sweat, wound exudate, and other fluids from seeping into the bed board system. This not only protects the lifespan of the bed board but also facilitates the cleaning and disinfection of the fitted sheet, reducing the risk of cross-infection.

[0015] Furthermore, the jack includes: a top support plate, with the pulley mechanism mounted on the top of the top support plate; a base, with a receiving chamber above the base, and two synchronously rotating and counter-rotating transmission teeth rotatably connected inside the receiving chamber; and a telescopic support assembly, which includes multiple sequentially hinged first and second linkage groups, the first and second linkage groups being hinged and forming multiple parallelogram structures, the top of the telescopic support assembly being hinged to the top support plate, and the bottom of the telescopic support assembly being hinged to the two side walls inside the receiving chamber.

[0016] By adopting the above-described scheme, and through the coordinated operation of the top support plate, base, receiving compartment, and telescopic support assembly, the jack of this application can achieve precise body position adjustment. The precise movement of the pulley mechanism within the sliding rail, the smooth transmission of the transmission gears, and the stable extension and retraction of the telescopic support assembly jointly ensure the accuracy and stability of the bed board during the adjustment process. The lifting and lowering adjustment of the jack can be achieved simply by controlling the switch and speed of the external power source.

[0017] Furthermore, the pulley mechanism includes: a pulley frame, which is mounted on the top of the top support plate; and a wheel body, which is rotatably connected to the pulley frame and is used to roll along the sliding rail.

[0018] By adopting the above solution, the high-precision rotation of the wheels and the optimized design of the pulley frame significantly improve the movement flexibility of the pulley mechanism within the sliding rail. Medical staff can easily move the bed board with only a small amount of external force, achieving quick and convenient position adjustment.

[0019] Furthermore, it also includes a tilting mechanism, which is located below the jack and is used to provide lifting force to one side of the bed board system.

[0020] By adopting the above solution, medical staff can easily raise and lower one side of the bed board using only a control panel or remote control. Compared with traditional raising methods, this significantly reduces the workload of medical staff and improves work efficiency.

[0021] Furthermore, the flipping mechanism allows the bed board system to be raised at an angle of 0-15° to the horizontal plane.

[0022] By adopting the above approach, an elevation angle range of 0-15° can meet the nursing needs of most patients, whether it is a slight adjustment of body position or a special treatment need, while avoiding slippage and discomfort caused by high-angle elevation.

[0023] Furthermore, the fitted sheet assembly has straps at its four corners.

[0024] By adopting the above solution, the stability of the fitted sheet assembly can be further improved.

[0025] Furthermore, in the fixing part of the seepage-proof bottom layer and the assembly part of the high-density sponge layer, one is felt and the other is burrs.

[0026] By adopting the above scheme, mechanical engagement can be formed, friction can be increased, and the slippage effect between the two can be reduced.

[0027] In summary, the adjustable nursing bed board provided by this utility model has the following technical effects:

[0028] 1. The jack moves along the sliding rail along the length of the bed board through the pulley mechanism, realizing the dynamic adjustment of the force point, breaking through the limitations of traditional fixed-point support. Clinical tests have shown that this design can expand the range of body position adjustment from 3-5 in traditional nursing beds to more than 12.

[0029] 2. It greatly expands the range of body position adjustment, enabling medical staff to flexibly adjust the patient's position according to the patient's specific treatment needs, thereby improving treatment effectiveness and efficiency;

[0030] 3. The sliding positioning system can limit the position of the pulley mechanism within the sliding rail, ensuring that the jack remains stable after being adjusted to the appropriate position. Attached Figure Description

[0045] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0046] Embodiment 1 of this utility model, as shown in Figures 1-8, discloses an adjustable nursing bed board: comprising a bed board system 1, a fitted sheet assembly 2, jacks 3, and a sliding positioning system 4. The bottom surface of the bed board system 1 is provided with a sliding rail 13 arranged along its length. Specifically, the bed board system 1 is used to install onto most medical bed frames 7. The bed board system 1 adopts a composite structure, including a high-density sponge layer 11 on the upper layer and a steel plate layer 12 on the lower layer. The high-density sponge layer 11 consists of multiple pieces spliced ​​onto the upper surface of the steel plate layer 12 to provide cushioning. The sliding rail 13 is located below the steel plate layer 12 and is arranged along the length of the bed. Optionally, the number of sliding rails 13 can be one or more. Similarly, the number of jacks 3 is not limited and can be increased or decreased according to actual needs. The fitted sheet assembly 2 is detachably mounted on the top surface of the bed board system 1. The top of the jack 3 is equipped with a pulley mechanism 5 that slides within the sliding rail 13. The sliding positioning system 4 restricts the position of the pulley mechanism 5 within the sliding rail 13. By sliding the pulley mechanism 5 within the sliding rail 13, the jack 3 can dynamically adjust its force application along the length of the bed board. This innovative design greatly expands the range of adjustment for body position angles, allowing medical staff to flexibly adjust the patient's position according to their specific treatment needs, thereby improving treatment effectiveness and efficiency. Simultaneously, the sliding positioning system 4 ensures the stability of the jack 3 after it has been adjusted to the appropriate position.

[0047] In some embodiments, to improve the ease of detachable connection between the fitted sheet assembly 2 and the bed board system 1, an assembly part 111 is provided on the top surface of the high-density sponge layer 11. The assembly part 111 is used for assembly with the fitted sheet assembly 2. Preferably, the assembly part 111 includes, but is not limited to, Velcro, high-strength magnets, or locking blocks. This ensures that the fitted sheet assembly 2 is firmly and stably fixed to the high-density sponge layer 11, guaranteeing the flatness and stability of the fitted sheet and preventing displacement or wrinkling during use. Preferably, the thickness of the high-density sponge layer 11 is 3cm-8cm, and the density is ≥50kg / m³. 3 The surface is covered with an antibacterial coating.

[0048] It should be noted that the sliding rail 13 can be an outwardly convex sliding rail groove welded to the bottom edge of the steel plate layer 12, or it can be an embedded concave sliding rail groove. This embodiment 1 does not make specific limitations.

[0049] In some embodiments, referring to Figures 9-10, to facilitate the adjustment of the lifting angle of the steel plate layer 12 by the jack 3 in different areas, the sliding rail 13 is designed as a head sliding rail 131, a torso sliding rail 132, and a lower limb sliding rail 133 connected end to end. When the head sliding rail 131, torso sliding rail 132, and lower limb sliding rail 133 are collinear, the pulley mechanism 5 can slide along the head sliding rail 131, torso sliding rail 132, and lower limb sliding rail 133. The steel plate layer 12 is designed as a head plate 121, a torso plate 122, and a lower limb sliding rail 133 that are hinged together. The head sliding rail 131 is located below the head plate 121, the torso sliding rail 132 is located below the torso plate 122, and the lower limb sliding rail 133 is located below the lower limb plate 123. The segmented sliding rail 13 design allows the jack 3 to make independent position adjustments for the head, torso, and lower limbs. At the same time, this design also facilitates personalized adjustments according to the patient's specific situation. For example, for patients with special needs in certain parts of the body, the comfort of the patient can be improved by adjusting the thickness of the sponge layer or the structure of the steel plate layer 12 in the corresponding parts.

[0050] In some embodiments, the fitted sheet assembly 2 comprises, from top to bottom, a surface layer 21, a middle layer 22, and a waterproof bottom layer 23. The surface layer 21 has a silicone particle matrix 211 on its surface. The middle layer 22 comprises memory foam and a temperature-regulating gel. Preferably, the surface layer 21 has a thickness of 2 mm, and its surface is molded with conical silicone particles with a height of 5 mm, arranged in a matrix. The silicone particles have good friction, effectively increasing the coefficient of friction between the fitted sheet and the patient's body, preventing patient displacement during position adjustment. The middle layer 22 is composed of a 2 cm thick memory foam and a 5 cm thick phase change gel layer. The temperature-regulating gel contains paraffin microcapsules with a phase change temperature of 32-36°C. The phase change gel layer is connected to an external circulating water bath system for precise temperature control. The memory foam has slow rebound properties, allowing it to adaptively deform according to the patient's body curves, evenly distributing the patient's body pressure across the entire fitted sheet surface, reducing the risk of pressure sores. The temperature-regulating gel has heat absorption and dissipation functions, automatically adjusting the fitted sheet temperature according to ambient temperature and the patient's body temperature. The impermeable bottom layer 23 uses a 0.5mm TPU waterproof membrane, which can effectively prevent liquids such as patient sweat and wound exudate from penetrating into the bed board system 1. This not only protects the service life of the bed board but also facilitates the cleaning and disinfection of the bed sheet, reducing the risk of cross-infection. The bottom surface of the impermeable bottom layer 23 is provided with a fixing part, which is used to fix it to the assembly part 111 of the bed board system 1. Preferably, one of the fixing part of the impermeable bottom layer 23 and the assembly part 111 of the high-density sponge layer 11 is felt and the other is burrs. In other embodiments, the specific structure of the two is not limited, as long as the fixing effect can be achieved.

[0051] In this embodiment 1, the jack 3 includes a top support plate 31, a base 32, and a telescopic bracket group 33. The top support plate 31 is made of aluminum alloy. The pulley mechanism 5 includes a pulley frame 51 and a wheel 52. The pulley frame 51 is mounted on the top of the top support plate 31, and the wheel 52 is rotatably connected to the pulley frame 51 for rolling along the sliding rail 13. The pulley frame 51 is fixed to the top support plate 31 by bolts; a receiving chamber is provided above the base 32, and two synchronously rotating and counter-rotating transmission gears 321 are rotatably connected in the receiving chamber. The transmission gears 321 are connected to an external driving device. When the transmission gears 321 rotate, they can drive the telescopic support assembly 33 to rotate; the telescopic support assembly 33 includes multiple first link groups 331 and second link groups 332 that are hinged in sequence. The first link groups 331 and second link groups 332 are hinged and enclose multiple parallelogram structures. The top end of the telescopic support assembly 33 is hinged to the top support plate 31, and the bottom end of the telescopic support assembly 33 is hinged to the two side walls inside the receiving chamber and simultaneously driven by the transmission gears 321. Through the coordinated work of the top support plate 31, the base 32, the receiving chamber, and the telescopic support assembly 33, the jack 3 of this application can achieve precise body position adjustment. The precise movement of the pulley mechanism 5 within the sliding rail 13, the smooth transmission of the transmission gear 321, and the stable extension and retraction of the telescopic support assembly 33 together ensure the accuracy and stability of the bed board during adjustment. The lifting and lowering adjustment of the jack 3 can be achieved simply by controlling the switch and speed of the external power source.

[0052] Optionally, the sliding positioning system 4 includes an electromagnetic magnet located within the sliding rail 13. The wheel 52 is made of a material capable of magnetically attracting the electromagnetic magnet. When the electromagnetic magnet is energized, it can be magnetically attracted and fixed to the wheel 52, preventing displacement and thus improving the stability of the lifting of the jack 3. In other embodiments, the sliding positioning system 4 can also be an electromagnetic brake and a mechanical pin, a gear and rack structure, or a Hall effect sensor, etc. This embodiment does not impose specific limitations.

[0053] In some embodiments, to enable the bed board to flip to the left and right sides of the body, a flipping mechanism 6 is provided below the jack 3 to provide lifting force to one side of the bed board system 1. Medical staff can easily raise and lower one side of the bed board using a control panel or remote control. Compared with traditional lifting methods, this greatly reduces the workload of medical staff and improves work efficiency. Preferably, the flipping mechanism 6 allows the bed board system 1 to be raised at an angle of 0-15° to the horizontal plane. This 0-15° lifting angle range can meet the nursing needs of most patients, whether for slight position adjustments or special treatment needs, while avoiding slippage and discomfort caused by high-angle lifting. Specifically, the flipping mechanism 6 includes a flipping motor 61, flipping support feet 62, and a flipping plate 63. The flipping motor 61 is mounted on the flipping support feet 62, and the flipping plate 63 is rotatably connected between the flipping support feet 62. The output end of the flipping motor 61 is driven by the flipping plate 63 to drive its rotation.

[0054] In some embodiments, to further improve the stability of the fitted sheet assembly 2, straps 24 are provided at the four corners of the fitted sheet assembly 2. These straps can be bound to the bed frame 7 and also to the four corners of the bed board system 1. Ropes that can be attached to the four corners can be provided. In other embodiments, guardrails can be provided at the edges of the bed frame 7 to prevent displacement of the fitted sheet assembly 2.

[0055] In use, first release the sliding positioning system 4. Then, adjust the number of jacks 3 and their positions within the sliding rail 13 according to the patient's condition. Insert each jack 3 so that it is detached from the ground for easy sliding. Once the designated position is reached, remotely activate the jack 3 so that the flipping structure at the bottom of the jack 3 contacts the bottom surface. Then, control the other jacks 3 to perform the above operation. After each jack 3 is in place, activate the sliding positioning system 4 to fix each jack 3. Then, push the jack 3 to lift the corresponding steel plate layer 12, thus forming a head-down, feet-up or head-up, feet-down position. The head-down, feet-up position is suitable for patients with lung diseases, digestive system diseases, pregnant women, orthopedic diseases, and shock patients. The head-up, feet-down position is suitable for patients with craniocerebral diseases, cervical spine diseases, and ophthalmological diseases. Then, fine adjustments can be made according to the specific position by controlling the rotation of the flipping mechanism 6 to change the height difference between the left and right sides of the patient for subsequent surgery or other operations.
