The terms used in this specification are for the purpose of describing specific embodiments only and are not intended to limit the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0028] See also Figures 1-3 A preferred embodiment of the present invention is a nursing aid device for assisting standing up, comprising: a bed and a support assembly.

[0029] The bed frame includes a first bed board 1, a second bed board 2, and a third bed board 3, which are hinged in sequence along a first direction. This allows the first bed board 1 to tilt upward relative to the second bed board 2, and the third bed board 3 to tilt downward relative to the second bed board 2. The first bed board 1 can tilt upward relative to the second bed board 2 to stably support the patient's back. The patient's legs and buttocks rest comfortably on the second bed board 2, while the area below the knees naturally hangs down as the third bed board 3 tilts downward. This allows patients to easily transition from a lying position to a sitting position without assistance, improving patient autonomy and convenience while reducing the workload of caregivers.

[0030] The support assembly includes a fixed bracket 14, a first swing support seat 12, a first movable frame 15, a second swing support seat 13, a second movable frame 16, and a reciprocating drive device; the fixed bracket 14 abuts against the bottom of the first bed board 1 and the bottom of the second bed board 2 to support the first bed board 1 and the second bed board 2; the first movable frame 15 is transmission-connected to the reciprocating drive device so as to be able to approach or move away from the third bed board 3 in the horizontal direction; the first swing support seat 12 abuts against the horizontal side of the first movable frame 15 so as to be driven by the first movable frame 15 relative to the fixed bracket 1 4 swings upward; the first swing support seat 12 is linked with the first bed board 1 so as to be able to push the first bed board 1 to tilt upward relative to the second bed board 2; the second movable frame 16 is transmission-connected with the reciprocating drive device so as to be able to approach or move away from the first bed board 1 in the horizontal direction; the second swing support seat 13 abuts against the horizontal side of the second movable frame 16 so as to be supported by the second movable frame 16 and swing downward relative to the fixed bracket 14; the second swing support seat 13 is linked with the third bed board 3 so as to be able to support the third bed board 3 to tilt downward relative to the second bed board 2.

[0031] In the support assembly, both ends of the reciprocating drive device are respectively connected to the first movable frame 15 and the second movable frame 16. The first swing support base 12 abuts against the horizontal side of the first movable frame 15, and the second swing support base 13 abuts against the horizontal side of the second movable frame 16. Under the action of gravity, the third bedplate 3 converts the vertically downward gravity into the force of the horizontal reciprocating drive device through the second swing support base 13. In addition, the first bedplate 1 also converts the gravity into the force in the horizontal direction through the first swing support base 12 and acts on the reciprocating drive device. These two forces can both be part of the force required to be output by the reciprocating drive device, reducing the burden on the drive device.

[0032] It can be understood that when the reciprocating drive device at both ends is not limited to being respectively connected to the first movable frame 15 and the second movable frame 16 in the auxiliary getting-up device for nursing in this embodiment, the basic solution can be: the reciprocating drive device can include two independent power sources, one of the independent power sources is drivingly connected to the first movable frame 15, and the other independent power source is movably connected to the second movable frame.

[0033] When it is necessary to change from the supine state to the sitting state, the reciprocating drive device moves horizontally towards the first bedplate 1, driving the first movable frame 15 and the second movable frame 16 to move synchronously. At this time, since the third bedplate 3 loses the support of the second movable frame 16, it tilts downward under the action of gravity and transmits the gravity component force to the reciprocating drive device. This design enables the reciprocating drive device to push the first swing support base 12 with a relatively small force, and then drive the first bedplate 1 to tilt upward relative to the second bedplate 2, that is, to realize the transformation from the supine state to the sitting state. When changing from the sitting state back to the supine state, the first bedplate 1 loses the support of the first movable frame 15, tilts downward under the action of gravity, and transmits the gravity component force to the reciprocating drive device. This design enables the reciprocating drive device to be pushed with a relatively small force, and then drive the third bedplate 3 to tilt upward relative to the second bedplate 2, that is, to realize the transformation from the sitting state to the supine state. In this way, whether changing from the supine state to the sitting state or from the sitting state to the supine state, the load on the reciprocating drive device is reduced. The sequential force transmission of the first bedplate 1, the first swing support base 12, the reciprocating drive mechanism, the second swing support base 13, and the third bedplate 3 realizes the synchronous and coordinated movement of the first bedplate 1 and the third bedplate 3, making the conversion process of the entire bed body smoother and more stable, improving the convenience and comfort of use, and reducing the working burden of the reciprocating drive device.

[0034] Working principle: When in the supine position, the first bed board 1 is mainly supported by the fixed bracket 14. When it is necessary to convert to the sitting position, the reciprocating driving device is started, driving the first movable frame 15 to move horizontally towards the first bed board 1. With the transmission of the first swing support seat 12, the first bed board 1 tilts upwards accordingly until it reaches the sitting position. At this time, the first swing support seat 12 supports on the first movable frame 15 to ensure reliable support for the patient's back. The reciprocating driving device simultaneously drives the second movable frame 16 to move horizontally towards the first bed board 1. Since the third bed board 3 loses the support of the second movable frame 16, it tilts downwards under the action of gravity, causing the patient's legs to hang naturally, presenting a sitting posture. The two ends of the reciprocating driving device are respectively connected to the first movable frame 15 and the second movable frame 16. While the first bed board 1 rises, the third bed board 3 descends synchronously. Through the coordinated action of the first swing support seat 12, the reciprocating driving device, and the second swing support seat 13, the forces transmitted from the first bed board 1 and the third bed board 3 to the reciprocating driving mechanism are in opposite directions on the same straight line, which can reduce the load on the reciprocating driving device.

[0035] Obviously, based on the bed body including the first bed board 1, the second bed board 2, and the third bed board 3 that are sequentially hinged along the first direction, so that the first bed board 1 can tilt upwards relative to the second bed board 2, and the third bed board 3 can tilt downwards relative to the second bed board 2, thereby enabling the bed body to be transformed from the supine position to the sitting position, and from the sitting position to the supine position. Moreover, by using the reciprocating driving device as the power source to drive the first movable frame 15 and the second movable frame 16 to respectively drive the first swing support seat 12 and the second swing support seat 13 in linkage. In this way, the first bed board 1 driven by the first swing support seat 12 in linkage, and the second bed board 2 driven by the second swing support seat 13 in linkage can achieve mechanized movement, replacing the labor of manually rotating the first bed board 1 and the second bed board 2, which helps to assist the patient to get out of bed and move.

[0036] The two ends of the reciprocating driving device are respectively connected to the first movable frame 15 and the second movable frame 16. By simultaneously controlling the reciprocating movement of the first movable frame 15 and the second movable frame 16 through the reciprocating driving device, the synchronous movement of the first bed board 1 and the third bed board 3 is achieved. The gravity received by the first bed board 1 and the gravity received by the third bed board 3 are transmitted through the first swing support seat 12, the first movable frame 15, the reciprocating driving device, the second movable frame 16, and the second swing support seat 13, and are converted into forces in opposite directions applied to the reciprocating driving device, thereby reducing the load on the reciprocating driving device. The auxiliary getting-up device has a simple structure, does not require complex pneumatic, hydraulic or mechanical structures, has good stability, low failure rate, and improves the reliability and service life of the device.

[0037] The reciprocating drive device includes a motor 19, a lead screw 20, a first linkage block and a second linkage block. The motor 19 is installed on the second bedplate 2. The motor 19 is in transmission connection with the lead screw 20 and drives the lead screw 20 to reciprocate along the axial direction of the lead screw 20. The first linkage block and the second linkage block are respectively movably sleeved on both ends of the lead screw 20. The first linkage block is linked and connected with the first movable frame 15. The second linkage block is linked and connected with the second movable frame 16 to drive the first movable frame 15 and the second movable frame 16 to approach or move away from the fixed bracket 14 in the horizontal direction. While the first bedplate 1 tilts upward, the second bedplate 2 tilts downward. The reciprocating drive device can also be two stepping motors 19, which respectively and independently drive the first bedplate 1 and the third bedplate 3 to rotate.

[0038] The reciprocating drive device further includes a guide seat. The guide seat is provided with an internal thread. The lead screw 20 passes through the guide seat and is matched with the internal thread. The setting of the guide seat ensures the axial reciprocating movement of the lead screw 20, reduces the possibility of the lead screw 20 deflecting when subjected to external forces, thereby improving the straightness and stability of the movement, prolonging the service life of the lead screw 20, and reducing the risk of failures caused by the deformation of the lead screw 20. A locking mechanism is provided on the guide seat. When the device is not operating, the guide seat can be locked to prevent the first bedplate 1 and the third bedplate 3 from tilting or shifting due to external forces. The safety of the nursing bed is improved, ensuring the stability and comfort of the patient in the non-working state of the device.

[0039] The bed body further includes a first mattress 9 laid on the top of the first bedplate 1, a second mattress 10 laid on the top of the second bedplate 2, and a third mattress 11 laid on the top of the third bedplate 3. The mattresses are made of soft and highly elastic materials, which can provide a comfortable support and lying experience for the patient, and at the same time help to relieve the body pressure and prevent the formation of pressure sores. The mattresses also have a certain shock-absorbing effect, which can buffer the patient's movements and reduce the discomfort that may be brought by the hard contact of the bedplates.

[0040] The bottom of the first movable frame 15 and the bottom of the second movable frame 16 are equipped with first walking wheels 17. When the device is operating, the first walking wheels 17 can reduce the friction between the movable frame and the ground, thus effectively reducing the load on the reciprocating drive device. The first walking wheels 17 are provided with locking mechanisms. When the device is not in operation, the locking mechanisms can firmly lock the walking wheels. Further preventing the first bed board 1 and the third bed board 3 from tilting or shifting due to external forces when the device is not in use, ensuring the safety of the patient in the non-use state and the stability of the device. The bottom of the fixed bracket 14 is equipped with second walking wheels 18. The second walking wheels 18 at the bottom of the fixed bracket 14 are used to move the assisted getting-up device. In case of an emergency, such as when the patient on the bed needs first aid or transfer, the caregiver can directly push the assisted getting-up device to the required position. Ensuring the convenience of device movement and improving the practicality and emergency response ability of the nursing bed. The second walking wheels 18 are also provided with locking mechanisms. When the assisted getting-up device does not need to be moved, the locking mechanisms can firmly fix the second walking wheels 18, preventing the device from shifting and avoiding discomfort or injury that the patient may suffer due to the sliding of the device.

[0041] On both opposite sides of the second bed board 2, there are first guardrails 4; on both opposite sides of the third bed board 3, there are second guardrails 5. When the patient is resting or turning over, the first guardrails 4 and the second guardrails 5 can effectively prevent the patient from slipping off the edge of the bed due to excessive turning amplitude, avoiding the possibility of secondary injury. When the assisted getting-up device is in the sitting state, the first guardrails 4 can also serve as the patient's assisted getting-up handrails. The patient can grasp the first guardrails 4 and, with the help of their stable supporting force, smoothly transition from the sitting state to the standing state, thus realizing safe and independent out-of-bed activities. The surfaces of the first guardrails 4 and the second guardrails 5 are wrapped with flexible materials such as rubber and silica gel, which can effectively buffer collisions and prevent the patient from being bruised. The first guardrails 4 are also provided with anti-slip patterns to increase friction, making it easier for the patient to grasp when standing up and reducing the risk of slipping.

[0042] The assisted getting-up device for nursing also includes a pillow 8, and the pillow 8 is adhered to the first mattress 9. The pillow 8 is adhered to the first mattress 9 by means of Velcro. When the first bed board 1 tilts upward, the Velcro of the pillow 8 ensures its firm adhesion and prevents slipping, ensuring that the patient's head and neck are always reliably supported. The Velcro adhesion method can also prevent the pillow 8 from shifting during the patient's sleep, causing a stiff neck.

[0043] On one side of the first bed board 1 away from the second bed board 2, there is a head protection board 6, and on one side of the third bed board 3 away from the second bed board 2, there is a foot protection board 7. The head protection board 6 can prevent the pillow 8 from falling and avoid the patient's head from touching the wall. The surface of the head protection board 6 facing the third bed board 3 is made of a flexible material such as rubber or silica gel, which can prevent the patient's head from being injured due to accidental bumps. The foot protection board 7 also has an anti-slip function. When the assisted getting-up device is adjusted to the sitting state, the foot protection board 7 can be used as a footrest to provide a stable stepping platform for the patient and avoid the feet directly touching the ground. The patient can put on shoes and socks on the foot protection board 7 and then get out of bed to move around.

[0044] There are at least two reciprocating drive devices, and the two reciprocating drive devices are spaced apart along the width direction of the second bed board 2. This enables the first movable frame 15 and the second movable frame 16 to be evenly stressed, prevents offset caused by single-point driving, and ensures the stability of the entire bed body during adjustment. The setting of the dual drive devices improves the smooth operation of the equipment, reduces shaking, and provides a safer and more comfortable use experience for the patient.
