[0003] The disclosure is of CN118924548A, which discloses a toilet assisting device for nursing elderly patients, comprising: a wheelchair, a detachably mounted toilet bucket, a square groove on the upper part of a slide slot for movably mounting a cylinder cover, handles symmetrically arranged on the back cushion of the wheelchair, an electric push rod on the lower part of the back cushion, and limit hooks symmetrically arranged on the rear part of the seat cushion of the wheelchair; a cross bar is arranged on the output shaft of the electric push rod, lifting plates are symmetrically arranged on both sides of the cross bar, and pull ropes are connected to the lower parts of both sides of the cross bar; an electromagnet is arranged on the front end wall of the square groove, and through holes for installing pull ropes are symmetrically arranged on the wall; an elastic element is arranged at the rear end of the cylinder cover for connecting to the seat, and ropes are symmetrically arranged at the front end, and after the ropes pass through the through holes on the wall of the square groove, they are restricted by the limit hooks on the wheelchair and connected to the cross bar.

[0004] The existing auxiliary wheelchairs for elderly care have a simple structure and are not equipped with a mechanism to assist elderly patients in standing up from the wheelchair. This is because the wheelchair seat is in a tilted backward state, ensuring that the elderly patient leans on the wheelchair at an angle. Although this method helps the elderly patient sit stably in the wheelchair, it makes it difficult for the elderly patient to stand up from the wheelchair, resulting in poor functionality and lack of practicality of the wheelchair.

[0005] To this end, we propose a multifunctional nursing device for geriatric cardiology. Summary of the invention

[0006] The purpose of the present invention is to provide a multifunctional nursing device for geriatric cardiology to solve the problems raised in the above-mentioned background technology.

[0007] To achieve the above-mentioned purpose, the present invention provides a multifunctional nursing device for elderly cardiology, comprising an auxiliary seat body; further comprising a sliding member, a movable member and a fixed plate rotatably connected to the auxiliary seat body, the fixed plate slidably cooperates with a movable plate for lifting and supporting elderly patients, the bottom of the fixed plate is rotatably connected with a movable plate, the movable plate is rotatably connected with two toggle plates matched with the movable plate through the sliding member, the fixed plate is rotatably connected with a reset rod matched with the reset of the toggle plate, the auxiliary seat body is self-rotating with a rotating plate, and the rotating plate causes the movable plate to reciprocate through the movable member;

[0008] The sliding member includes a sleeve plate that slides with the movable plate. The sleeve plate enables the toggle plate to move along the movable plate through the movable member, thereby pressing and driving the fixed plate and the lifting movable plate to tilt synchronously, making it convenient for the elderly patient's upper limbs to move forward and away from the backrest of the auxiliary seat body.

[0009] Preferably, the sliding part also includes a protrusion rotatably connected to the toggle plate through a torsion spring, a first sliding groove slidably matched with the protrusion is opened on one side of the movable plate, and a second sliding groove matched with the movable part is opened on the other side of the movable plate, and a bracket for supporting the arm of an elderly patient is fixedly connected to the top of the movable plate, and a limit member is provided between the movable plate and the fixed plate.

[0010] Preferably, the limiting member includes a plurality of limiting plates connected and fixed to the movable plate, the fixed plate is provided with a limiting groove slidingly matched with the limiting plates, and the auxiliary seat body is fixedly connected to a rotating shaft rotatably connected to the fixed plate and the movable plate.

[0011] Preferably, the reset rod is a U-shaped structure, and a lifting plate is fixedly connected to the middle of the reset rod.

[0012] Preferably, the movable part includes a connecting shaft that slidably cooperates with the movable plate, the connecting shaft is connected and fixed to the edge of the rotating plate, a cylinder is fixedly connected to the auxiliary seat body, and a power part is provided between the cylinder and the rotating plate.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] The toggle plate rotates back and forth alternately at a certain angle, so that the moving plate moves upward layer by layer, driving the bracket to hold the upper body of the elderly patient away from the auxiliary seat body. And the toggle plate moves along the movable plate, so that the toggle plate far from the elliptical wheel position approaches the moving plate, and the other toggle plate moves away from the moving plate. Thus, the force exerted by the toggle plate far from the elliptical wheel position on the moving plate is greater than the force exerted by the other toggle plate on the moving plate, causing the moving plate to tilt, and not affecting the movement of the moving plate rising along the fixed plate. Therefore, the rising bracket tilts, enabling the back of the elderly patient to separate from the auxiliary seat body, assisting the elderly patient to stand up from the auxiliary seat body.

DETAILED DESCRIPTION

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] See also Figures 1 - 13 The present invention provides a multifunctional nursing device for elderly cardiology, comprising an auxiliary seat body 1; further comprising a sliding member, a movable member and a fixed plate 2 rotatably connected to the auxiliary seat body 1, wherein a movable plate 3 (with ratchet plate structures on both sides) for lifting and supporting elderly patients is slidably matched on the fixed plate 2, and a movable plate 4 is rotatably connected to the bottom of the fixed plate 2, and two toggle plates 5 (with ratchet plate structures) matched with the movable plate 3 are rotatably connected in the movable plate 4 through a sliding member, and a reset rod 6 matched with the toggle plate 5 is rotatably connected to the fixed plate 2, and a self-rotating plate 7 is self-rotating on the auxiliary seat body 1, and the self-rotating plate 7 reciprocates the movable plate 4 through the movable member, wherein a shell can be provided to protect the movable plate 3, and a notch is provided on the shell to facilitate the movement of the movable plate 44 and the toggle plate 5;

[0034] The sliding member includes a sleeve plate 8 that is slidably matched with the movable plate 4. The sleeve plate 8 enables the toggle plate 5 to move along the movable plate 4 through the movable member, thereby pressing and driving the fixed plate 2 and the lifting movable plate 3 to tilt synchronously, so as to facilitate the elderly patient's upper limbs to move forward and leave the backrest of the auxiliary seat body 1;

[0035] Through the movable part, while the movable plate 4 and the sleeve plate 8 make reciprocating rotations at a certain angle, the sleeve plate 8 moves along the movable plate 4. In this way, the toggle plate 5 makes reciprocating rotations at a certain angle alternately, so that the moving plate 3 moves upward layer by layer, driving the bracket 12 to hold the upper body of the elderly patient away from the auxiliary seat body 1. And the toggle plate 5 moves along the movable plate 4, so that the toggle plate 5 far from the elliptical wheel 24 approaches the moving plate 3, and the other toggle plate 5 moves away from the moving plate 3. Thus, the force exerted on the moving plate 3 by the toggle plate 5 far from the elliptical wheel 24 is greater than the force exerted on the moving plate 3 by the other toggle plate 5, causing the moving plate 3 to tilt, and not affecting the movement of the moving plate 3 along the fixed plate 2 upward. Therefore, the ascending bracket 12 tilts, enabling the back of the elderly patient to separate from the auxiliary seat body 1, assisting the elderly patient to stand up from the auxiliary seat body 1. This method is convenient to operate and has a strong assisting effect.

[0036] The sliding part further includes a convex block 9 rotatably connected to the toggle plate 5 through a torsion spring. A first sliding groove 10 slidably engaged with the convex block 9 is formed on one side of the movable plate 4, and a second sliding groove 11 engaged with the movable part is formed on the other side of the movable plate 4. A bracket 12 for holding the arm of the elderly patient is fixedly connected to the top of the moving plate 3. A limiting part is provided between the moving plate 3 and the fixed plate 2.

[0037] Through the movable part, while the movable plate 4 and the sleeve plate 8 make reciprocating rotations at a certain angle, the sleeve plate 8 moves along the movable plate 4.

[0038] That is, the convex block 9 drives the two toggle plates 5 to make synchronous reciprocating rotations, and the two toggle plates 5 move alternately reciprocally, acting on the moving plate 3 to make the moving plate 3 move upward, thereby driving the bracket 12 to move upward to hold the arm of the elderly patient.

[0039] At the same time, the convex block 9 drives the toggle plate 5 to move along the first sliding groove 10, driving the two toggle plates 5 to move. The pressing action of one of the toggle plates 5 on the moving plate 3 is greater than the pressing action of the other toggle plate 5 on the moving plate 3. Thus, the ascending moving plate 3 tilts, and the ascending bracket 12 tilts, enabling the back of the elderly patient to separate from the auxiliary seat body 1.

[0040] The limiting part includes a plurality of limiting plates 13 fixedly connected to the moving plate 3. A limiting groove 14 slidably engaged with the limiting plates 13 is formed in the fixed plate 2. The auxiliary seat body 1 is fixedly connected with a rotating shaft 15 rotatably connected to the fixed plate 2 and the moving plate 3. Through the action of the limiting plates 13 and the limiting groove 14, it is ensured that while the moving plate 3 rotates with the fixed plate 2, it does not affect the movement of the moving plate 3 along the direction of the fixed plate 2, facilitating the rotation of the moving plate 3 while lifting, so that the bracket 12 rotates the upper limb angle of the elderly patient while lifting the upper limb of the elderly patient, enabling the elderly patient to stand up from the auxiliary seat body 1 conveniently.

[0041] The reset rod 6 is a U-shaped structure, and a lifting plate 16 is fixedly connected to the middle of the reset rod 6. When the elderly patient stands up from the auxiliary seat body 1, the cylinder 18 is reset by key operation, and at the same time, the lifting plate 16 is moved upward by hand or other operation methods (the elderly patient has stood up at this time, and the weight of the auxiliary seat body 1 is light, which is easy for the elderly patient to operate), so that the reset rod 6 rotates, and the reset rod 6 rotates to contact the toggle plate 5, so that the toggle plate 5 is separated from the moving plate 3;

[0042] The movable plate 3 automatically moves downward without the action of the toggle plate 5 , and finally, the lifting plate 16 is released, and under the action of the toggle spring, the toggle plate 5 is engaged with the movable plate 3 again.

[0043] The movable part includes a connecting shaft 17 that is slidably matched with the movable plate 4, the connecting shaft 17 is connected and fixed to the edge of the rotating plate 7, a cylinder 18 or an electric telescopic rod is fixedly connected to the auxiliary seat body 1, and a power part is provided between the cylinder 18 and the rotating plate 7;

[0044] The power member drives the rotating plate 7 to rotate in its original position, thereby driving the connecting shaft 17 to make a circular motion. The connecting shaft 17 can slide along the movable plate 4, so that the connecting shaft 17 in circular motion drives the movable plate 4 to reciprocate at a certain angle with the rotating shaft 15 as the rotation center, thereby driving the protrusion 9 and the toggle plate 5 to reciprocate at a certain angle synchronously.

[0045] The power member includes a gear 19 rotatably connected to the auxiliary seat body 1, the central axis of the gear 19 is fixedly connected to the central axis of the self-rotating plate 7, the telescopic shaft of the cylinder 18 is fixedly connected to a toothed plate 20 meshing with the gear 19, and a buffer is provided between the end of the toothed plate 20 and the sleeve plate 8;

[0046] The cylinder 18 is started, so that the telescopic shaft of the cylinder 18 is extended, driving the toothed plate 20 to move, and on the one hand, driving the gear 19 to rotate at the original position, so that the self-rotating plate 7 rotates at the original position, and cooperates with the connecting shaft 17 to make the movable plate 4 reciprocate at a certain angle with the rotating shaft 15 as the rotation center, thereby driving the toggle plate 5 to reciprocate at a certain angle, and under the action of the torsion spring, the movable plate 3 moves upward along the fixed plate 2, thereby driving the bracket 12 to move upward, holding the elderly patient's arm, so that the elderly patient's upper body is lifted, and it is convenient for the elderly patient to stand up from the auxiliary chair body 1;

[0047] On the other hand, the movement of the tooth plate 20 under the action of the buffer makes the sleeve plate 8 move along the movable plate 4, thereby making the protrusion 9 move along the movable plate 4 without affecting the reciprocating rotation of the toggle plate 5 at a certain angle, so that the two toggle plates 5 move, one toggle plate 5 moves away from the movable plate 3, and the other toggle plate 5 approaches the movable plate 3. The two toggle plates 5 are always engaged with the movable plate 3, and the inclination angles of the two toggle plates 5 are inconsistent, thereby pressing the movable plate 3 to tilt, so that the bracket 12 tilts synchronously.

[0048] The buffer member includes a first connecting plate 21 fixedly connected to the toothed plate 20. The end of the sleeve plate 8 is rotatably connected to a second connecting plate 22 that is slidably engaged with the second sliding groove 11. A compression spring 23 is hung between the second connecting plate 22 and the first connecting plate 21. When the toothed plate 20 moves along with the cylinder 18, it drives the first sleeve plate 8 to move, squeezing the compression spring 23, so that the second connecting plate 22 drives the sleeve plate 8 to move away along the direction of the movable plate 4. And due to the rotational connection relationship between the second connecting plate 22 and the sleeve plate 8, the reciprocating movement of the movable plate 4 does not affect the movement of the second connecting plate 22;

[0049] The sleeve plate 8 that moves away along the direction of the movable plate 4 drives the two toggling plates 5 to move synchronously. The convex block 9 near the second connecting plate 22 moves away from the moving plate 3, while the convex block 9 far from the second connecting plate 22 moves closer to the moving plate 3. Under the action of the torsion spring, the two toggling plates 5 are clamped on the moving plate 3. Only the inclination angles of the two toggling plates 5 are different, and the distances between the moving plate 3 and the two convex blocks 9 are different. Under the inclination action of the toggling plate 5, the moving plate 3 is gradually inclined. Under the action of the limiting member, the fixing plate 2 is inclined synchronously, so that the bracket 12 is inclined. The simultaneously rising bracket 12 is inclined, that is, while lifting the upper body of the elderly patient upward, the upper body of the elderly patient is tilted forward, facilitating the back of the elderly patient to disengage from the backrest of the auxiliary seat body 1, facilitating the elderly patient to stand up from the auxiliary seat body 1, and preventing the elderly patient from sitting too deep in the auxiliary seat body 1 and being unable to stand up from the auxiliary seat body 1.

[0050] The front end of the auxiliary seat body 1 is rotatably connected with a plurality of elliptical wheels 24 arranged in an array for facilitating obstacle crossing. Through the rotation of the plurality of elliptical wheels 24 distributed at intervals, it is convenient to cross the obstacle ground.
