Description

Bed chair system for horizontally moving human body

Technical Field

The invention belongs to the technical field of medical and nursing equipment, and particularly relates to a bed-chair system for horizontally moving a human body.

Background

At present, during the nursing process of patients in hospitals or at home, the patients and nursed persons are inevitably required to be spatially transferred; however, the applicant found that: the patient and the nursed person are usually carried to the wheelchair by the bed, and then are carried to the bed by the wheelchair after the wheelchair completes the task of spatial movement of the patient, so that the physical strength of the medical care personnel and the nursed person is greatly tested, the labor intensity is high, certain potential safety hazards are caused, particularly, the patient who just does an operation soon or needs to keep relatively stable body needs to be lifted to the wheelchair from the bed and to the bed from the wheelchair is very difficult, and the problem cannot be completely solved even if the patient is carried in a mechanical carrying mode. Such as: at present, the integrated nursing products are mainly divided into the following products. 1) The bed-chair is shifted by the aid of a conveyor belt, 2) an improved basic function bed system, 3) a lateral separation type integrated bed-chair and 4) a longitudinal separation type integrated bed-chair. The bed-chair separable nursing function provides a new idea for the space transfer of patients, fundamentally eliminates the trouble of patients from beds to wheelchairs, and aims at the respective advantages and disadvantages of the various products (see table 1-1).

TABLE 1-1 comparison of Integrated bed-chair Care System

In addition, the displacement of the bedridden old people is an important link in the nursing process of the disabled old people, the good auxiliary displacement scheme not only reduces the working strength of nursing personnel, avoids unnecessary injuries possibly occurring in the transfer process, but also endows the patients with certain self-care ability and self-respect feeling, and achieves the purpose of improving the life quality. However, this technique still has significant design drawbacks at present.

In order to realize the displacement nursing of patients, special patient nursing displacement machines (basket type displacement machines, such as electric displacement machines of Bai-Haohi medical science and technology Limited company in Guangzhou city) appear on the market and are matched with the intelligent nursing bed. On the premise of not influencing the performance of the intelligent nursing bed, the complexity of the fusion design of the bed and the chair is reduced, and incapacitated or semi-incapacitated patients can be easily transferred to a wheelchair, a closestool or a bathtub from a medical bed. However, the basket type shifting machine is not very convenient to use, needs more manual participation of nursing staff, and is not comfortable for users to use, so that the comfort level is greatly reduced.

In addition, the lifting and translating device 3 further comprises rails 38, the rails 38 are arranged on the ground on the front and back sides of the bed 1 and the wheelchair 2, and the front and back translation supports 32 and the back translation supports 33 can respectively move back and forth on the rails 38 arranged on the front and back sides of the bed 1 and the wheelchair 2. The track 38 may be a groove embedded in the ground, the bottom of each of the front and rear translation support frames 32 and 33 is provided with a roller 321, and the front and rear translation support frames 32 and 33 are also provided with a driving motor (not shown in the drawings, the driving motor has a locking function), and the driving motor is in driving connection with the roller. Therefore, the translation stability of the lifting translation device 3 can be further improved, and the safety is higher.

Moreover, the front translation support frame 32 and the rear translation support frame 33 are provided with a concave outlet 39 through which the wheelchair 2 can pass (of course, at least the front translation support frame 32 or the rear translation support frame 33 is provided with the outlet 39), and the lower end of the outlet 39 is close to the ground, so that the wheelchair 2 can conveniently go in and out, and the use is more convenient.

In addition, the left side and the right side of the lifting frame 31 are provided with the guardrails 30, so that the human body is effectively prevented from turning over from the lifting frame 31, the safety is obviously improved, and the psychological pressure of the patient is further reduced.

Meanwhile, the bed-chair system for horizontally transferring the human body can also be provided with a lifting position detection device for detecting the lifting position of the lifting frame 31 in the lifting and horizontally moving device 3 and a horizontally moving position detection device for detecting the horizontally moving position of the lifting and horizontally moving device 3. The lifting position detection device includes an upper limit hall sensor and a lower limit hall sensor (not shown) disposed in the lifting driver 36, and when the lifting driver 36 rises to trigger the upper limit hall sensor or falls to trigger the lower limit hall sensor, the lifting driver 36 stops moving. The translation position detection device may be a photoelectric switch or a travel switch, and the photoelectric switch or the travel switch is triggered when the lifting translation device 3 moves horizontally to the initial position or the final position (for example, when the lifting translation device 3 moves to the initial position or the final position, the photoelectric switch is shielded and triggered). Therefore, the lifting translation device 3 can be accurately positioned and controlled in lifting movement and translation movement, and has good repeatability and high safety.

Of course, the lifting and translating device 3 may also include a lifting frame 31, a front hanging and translating bracket, a rear hanging and translating bracket and a hanging and sliding rail (none of which are shown in the figure); the hanging sliding rails are fixed above the front side and the rear side of the bed 1 and the wheelchair 2, the front hanging translation support and the rear hanging translation support are respectively installed on the hanging sliding rails above the front side and the rear side of the bed 1 and the wheelchair 2 in a reciprocating mode and are provided with vertical lifting suspension arms, and the front end and the rear end of the lifting frame 31 are respectively connected and fixed on the vertical lifting suspension arms of the front hanging translation support and the rear hanging translation support.

The driving motors on the lifting driver 36, the front translation supporting frame 32 and the rear translation supporting frame 33 can also be stepping motors, and the accurate positioning can also be realized by controlling the number of pulses for driving the stepping motors to move, specifically: the pulse equivalent stroke of the stepping motor can be determined by calculating the step angle of the stepping motor, the reduction ratio of the gear reduction mechanism and the stroke of one circle of gear movement. When the stroke needs to be determined by movement, the stroke is divided by the pulse equivalent stroke of the stepping motor to obtain the accurate pulse number, and the accurate positioning can be realized by controlling the pulse number of the stepping motor.

While the foregoing is directed to the preferred embodiment of the present invention, it will be understood by those skilled in the art that various changes and modifications may be made without departing from the spirit and scope of the invention.
