Description

Mobile lifting and folding bath bed

technical field

The invention relates to the field of rehabilitation aids for the disabled, in particular to a mobile lifting and folding bathing bed for helping the disabled to bathe in a bathroom.

Background technique

At present, for the disabled and the elderly who have weak or lost lower limb standing and walking abilities, in daily life, when they need to take a bath, the traditional nursing method is to carry the disabled person by at least one caregiver. Even if the physical fitness of the caregiver allows it, the elderly or patients may not feel comfortable. Even if there is a transfer device, since the height of the transfer device is not consistent with the height of the hospital bed, it is necessary for the nursing staff to carry the patient from the hospital bed to the transfer device. The whole process is labor-intensive, and there are certain safety hazards at the same time.

For the disabled or the elderly who cannot take care of themselves in daily life, the problem of daily bathing is a problem encountered by family members or nursing staff. Due to the lack of suitable bathing tools, it is impossible to bathe the disabled who have bathing requirements, which affects to a certain extent. patient recovery and life.

In order to improve the daily bathing conditions of the handicapped and improve the rehabilitation level of the handicapped, it is necessary to provide a convenient and practical nursing type bathing bed to solve the problem. At present, there are many bathing bed products, but they cannot meet the requirements of patients in terms of function and practicability. Most of the products do not meet the real needs of patients, nor do they better consider reducing the workload of nursing staff.

Lifting armrests for easy transfer 5;

The base 1 is a frame 101, and the four corners of the frame are provided with braked universal casters 102, the front end of the frame is connected with a four-bar linkage mechanism 2, and the rear end of the frame is connected with an electric pusher in the middle. The bottom of the rod 6, the front end of the front end telescopic rod 7 of the electric push rod is hinged with the middle connecting cross bar 103 of two four-bar linkage mechanisms 2 arranged side by side;

Described four-bar linkage mechanism 2 comprises following short connecting rod 201, upper short connecting rod 203, lower long connecting rod 204, upper long connecting rod 202, the two ends of this lower short connecting rod 201 are connected with the lower long connecting rod 204 lower ends respectively. 1. The lower end of the upper long connecting rod 202 is hinged, and the two ends of the upper short connecting rod 203 are respectively hinged with the upper end of the lower long connecting rod 204 and the upper end of the upper long connecting rod 202; The upper end of the connecting rod 204 is extended with a long extension rod 9;

The foldable bed body 3 includes a headrest bed body 301, a front bed body 302, a middle bed body 303, and a rear bed body 304. The headrest bed body 301 is folded and hinged with the front end of the front bed body 302. end and the front end of the middle bed body 303 are hinged, and the front end of the rear bed body 304 is folded and hinged with the rear end of the middle bed body 303; the lower end of the middle bed body 303 is fixed to the short extension rod 8 of the upper short link 203 of the four-bar linkage mechanism 2 connect;

The backrest lifting mechanism 4 includes a support runner 401, the support frame 402 of the support runner 401 is connected with the two sides of the front bed body 302, and the support runner 401 is arranged on the extended upper end of the lower long connecting rod 204. On the top of the long extension rod 9;

The lifting handrail 5 includes an arc-shaped handle 501 , and a support rod 502 is hinged inside the arc-shaped handle 501 .

Wherein, on the headrest bed body 301 , the front bed body 302 , the middle bed body 303 , and the rear bed body 304 , wide waterproof belts 305 are wound horizontally and vertically at intervals.

Wherein, the inner side of the curved handle 501 of the lifting handrail is provided with a fixed pin shaft 503, and the pin seat 504 of the fixed pin shaft 503 is fixedly connected with the side upper end of the pole 502, and the upper end of the fixed pin shaft 503 enters and exits the curved handle. 501 inside the pin hole 505.

Wherein, the lower short connecting rod 201 is a triangle, the upper top of the triangle is hinged with the lower end of the upper long connecting rod 202, the lower top of the triangle is fixedly connected to the upper left end of the frame 101, and the right end of the triangle is fixedly connected to the frame 101.

Four universal casters 102 with brakes are installed on the four corners of the base 1, which can realize the translation of the bathing bed in any direction and the rotation along any axis, so as to facilitate access to places that are inconvenient to enter; the upper part of the base 1 and the four-bar linkage mechanism 2 Connection, the electric push rod 6 and the control box 8 are also fixed on the base 1.

The lower part of the four-bar linkage mechanism is connected to the base, and the upper part is connected to the foldable bed body 3, and the lifting of the bed surface is driven under the pushing and pulling action of the front end telescopic rod 7 of the electric push rod. Through the size and structure design of four links, the center of gravity is always kept within 150mm before and after the center of the base during the lifting process of the bed surface, ensuring the stability and safety of its movement. In terms of strength design, both weight and rigidity are considered, so that even though it is relatively light, it can control the left and right shaking of the bed surface within 5mm.

The bed surface material is fixed on the bed frame of the foldable bed body 3 with a bandage structure. This material and structure mode facilitates the cleaning of the bed surface, and makes it more comfortable for the patient to lie on the bed surface and is not easy to slide. The bed frame adopts a specially designed folding mechanism, which can ensure that the bed frame is flat when it is laid down, and does not hinder the patient from moving in and out of the bathing bed. When not in use, the bed body can be folded to reduce the length of the bed body.

Backrest lifting mechanism: through the extension of the pull rod in the four-bar linkage mechanism, without increasing the power source, when the bed body is raised, the pull rod also rotates clockwise and rises, and the rollers of the backrest part of the bed frame are turned to make the backrest rotate raised at an angle. The extension part can also be lifted horizontally by removing the extension part.

Lifting and lowering of the arc-shaped armrest: grab the armrest and pull it up, and the armrest will turn clockwise to raise it. When the rotating rod is perpendicular to the armrest, the pin shaft will be inserted into the pin hole of the armrest by spring pressure, and the armrest will be locked at the highest position. Do not move. Pull down the bracelet on the pin shaft, pull the pin shaft out from the pin hole of the armrest, press down the arc-shaped armrest counterclockwise, and then the armrest can be put down.

The above are the preferred embodiments of the present invention and the technical principles used therefor. For those skilled in the art, without departing from the spirit and scope of the present invention, any technical solution based on the present invention Obvious changes such as equivalent transformation and simple replacement all fall within the protection scope of the present invention.
