Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of nursing beds, in particular to a split type nursing bed for health care. BACKGROUND

[0002] A nursing bed is a medical auxiliary device designed for people with limited mobility or long-term bedridden, mainly used to help patients adjust their posture, assist with daily care, and prevent complications. Its core function is to adjust the angle and height of different parts of the bed body flexibly, allowing users to lie or sit up in a more comfortable position, while also reducing the work intensity of nursing staff in turning over, cleaning, and feeding.

[0003] Traditional integrated nursing beds have a large overall size, which faces serious transfer bottlenecks in home care scenarios. Actual measurements show that when the width of a conventional nursing bed exceeds 90 cm, it cannot pass through 76% of residential door frames (standard door width 80 cm) and old elevator cars. Most existing detachable bed bodies use bolts for connection, which requires special tools and takes more than 15 minutes to disassemble and assemble, and the connecting parts are easy to lose. After reassembly, the structure is not rigid enough, causing the bed body to shake;

[0004] The current electric nursing bed's shifting and turning functions are mutually exclusive: shifting relies on nursing staff manually dragging the patient (which can cause skin abrasions), while the electric turning mechanism can only adjust the angle of the back / legs and cannot achieve body position translation.

[0005] Therefore, we have developed a new split type nursing bed for health care. SUMMARY

[0006] (I) Technical problems solved

[0007] In view of the deficiencies of the prior art, the present application provides a split type nursing bed for health care, which solves the problem that the overall size of the traditional integrated nursing bed is too large, resulting in limited transfer (unable to pass through narrow doors / elevators), and the existing detachable solution is complicated to disassemble and assemble, and the reassembled structure is not rigid enough. At the same time, the shifting and turning functions of the electric nursing bed are mutually exclusive - shifting relies on manual dragging which can cause skin damage, the turning mechanism cannot translate the body position, and the lack of coordination increases the risk of nursing.

[0033] (Three) beneficial effects

[0034] The application provides a split type health care nursing bed.

[0035] 1. This modular, split-type nursing bed allows it to be disassembled into independent functional units, significantly reducing overall size and individual unit weight. This structure overcomes the limitations of traditional nursing beds in narrow spaces such as doorways and elevators, significantly improving transport efficiency. The connecting bed body and side panels are quickly reassembled through the insertion and positioning of assembly blocks and slots, while double-locking components ensure connection rigidity, solving the problem of installing large medical equipment in homes. The split configuration facilitates storage and transportation, while the reassembled version maintains complete nursing functionality, balancing usage intensity and adaptability to different scenarios.

[0036] 2. This split-type nursing bed integrates a pressure detection matrix within the movable bed frame, which can sense the human body's position distribution in real time. This, along with the electric push assembly and the transfer cloth rewinding mechanism, forms a closed-loop control system. When the transfer cloth is used to horizontally move the user, the pressure data triggers an automatic start-stop mechanism to ensure accurate positioning. The target side of the bed then adjusts its angle, assisting in turning the user through the rotation of the support shaft. This multi-system collaboration simplifies the traditional multi-person transfer and turning operations into a single-person controllable process, reducing the intensity of care and avoiding the risk of secondary injury caused by manual handling.

[0037] 3. This modular nursing bed allows for independent maintenance and upgrades of each functional module, extending the equipment's lifespan. The overall technical solution utilizes mechatronics to systematically address the challenges of position management for long-term bedridden patients. Attached Figure Description

[0055] Working principle:

[0056] Split carrying operation:

[0057] The operator rotates the hand wheel 14 to drive the bidirectional screw rod 17 to rotate, the bidirectional screw rod 17 drives the locking block 18 thereon to exit from the locking groove 23 in the assembly block 24, the locking is released, the side bed body 2 is pulled outward, the assembly block 24 on the side bed body 2 is completely separated from the assembly groove 20 on the two sides of the connecting bed body 1. At this time, the nursing bed is split into one connecting bed body 1 and two independent side bed bodies 2 modules, facilitating carrying. When reassembling, the assembly block 24 of the side bed body 2 is inserted into the assembly groove 20 of the connecting bed body 1 for positioning, and after alignment, the hand wheel 14 is reversely rotated to drive the locking block 18 to enter the locking groove 23 in the assembly block 24 for locking and fixing.

[0058] Auxiliary shifting and turning-over operation:

[0059] Shifting preparation: the nursing staff starts the motor 3 in the shell 4 on the side opposite to the target turning-over direction. The motor 3 drives the winding roller 26 to rotate, and winds the one end of the shifting cloth 9 on this side. At the same time, the winding roller 26 in the shell 4 on the other side synchronously releases the shifting cloth 9. The winding action pulls the shifting cloth 9 laid on the patient's body to move the patient stably to the side bed body 2 on the side where the winding is started.

[0060] Shift stop: When the patient's body is fully moved to the target side bed 2, the pressure sensor 27 on the movable bed 13 senses a stable pressure signal through the detection plate 29. After receiving this signal, the control system automatically commands the side motor 3 to stop the winding action, and the patient is accurately stopped at the target position.

[0061] Auxiliary turning: After confirming that the patient has been positioned at the target side bed 2, the nursing staff starts the electric push rod 12 of the target side bed 2. The electric push rod 12 is extended, and its movable end pushes the bottom of the movable bed 13 upward through the connecting seat 11 and the connecting block 10. The movable bed 13 is then rotated upward around its support shaft 25. As the movable bed 13 forms an angle, the patient's body is turned from a lying position to a lateral position under the combined action of gravity and the lifting bed surface, completing the turning action. The other side bed 2 remains horizontal to provide support. The fixed end of the electric push rod 12 is installed on the support frame 6 through the fixed block 16 and the fixed seat 15.

[0062] Reset: After the turning care is completed, the electric push rod 12 of the target side bed 2 is shortened to slowly lower the lifted movable bed 13 back to the horizontal position. If the patient needs to be moved back to the original position or the other side, the motor 3 in the corresponding side shell 4 can be operated to wind the shift cloth 9.
