Abstract

PROBLEM TO BE SOLVED: To prevent oppression onto one's body or positional deviation of the body by forming a reclining bed so that the waist seat moves to the front downward direction of the foot while receding and at the same time the foot part moves to the front downward direction of the foot while reclining forward, when the backrest is raised up. SOLUTION: When the lower end of a link 6 for raising the back is pulled to a motor 2 for raising the back by the motor 2 to raise a backrest, the backrest 3 is pushed up by the upper end of the link 6. In this time, the backrest 3 is rotated upward around a support point 15 and at the same time, an inlerlocking link 7 pivotted to the link 6 rotates a link 8 reclining the waist part forward, to the downward direction of the foot in accordance with the upward movement of the link 6. And since the link 8 is pivotted to the waist part 4, the waist part 4 is moved to the downward direction of the foot. And since the waist part 4 and the foot part 5 are rotatably connected to each other at the sliding support point 10, the sliding support point moves to the downward direction of the foot part while sliding on a slide shaft 9.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bed suitable for nursing a seriously ill patient or a bedridden elderly person.

[0002]

2. Description of the Related Art In general, for those who are likely to spend a long time in bed, such as seriously ill patients, the elderly, and the disabled, lying on the bed is a matter of lifestyle. It is not good from the top, from the viewpoint of functional recovery, and from the viewpoint of preventing bedsores. From such a viewpoint, so-called reclining, such as a structure in which the backrest occurs, a structure in which the waist and feet are in a mountain shape in conjunction with the occurrence of the backrest, and a structure in which the backrest, the waist, and the feet can independently change their angles, etc. Beds are widely used.

[0003] However, in the conventional reclining bed, when the backrest is raised, the patient's body is pushed forward and upward, and the feeling of pressure from the back and the feeling of hanging the clothes while lifting the clothes are raised as problems.

[0004] As a result, the position of the patient's body with respect to the bed shifts in the downward direction each time the user reclines. The caregiver must move the heavy patient's body each time to relieve pain and change position,
It is very hard work. This is one of the causes that makes patients bedridden and less likely to occur.

In order to solve such a problem, the position of the rotation fulcrum of the backrest portion is devised, or the bent portion of the backrest portion is constituted by multiple joints so that the backrest portion bends gently and smoothly. Something that can be adjusted in length is provided. In addition, it has been proposed that the backrest be raised while moving backward.

However, when actually used, the effect is insufficient, and the feeling of pressure on the body and the displacement of the body have not been solved.

[0007]

As described above, in the conventional reclining bed, it is difficult to fundamentally solve the feeling of pressure on the body and the displacement of the body by devising the position and shape. You have to change the structure fundamentally so that you don't pull your back up when you lift your back and don't push it forward.

[0008]

In order to achieve the above object, a bed according to the present invention is constructed such that the backrest and the waist / foot are not connected directly at the fulcrum, but are independently constructed, and the backrest is raised. The backrest rises as it sinks down, and in conjunction with the movement, the waist is linked by a link so that it moves backward greatly while tilting backward. At this time, the foot pivotally connected to the waist also moves forward while leaning forward. Therefore, the waist and the legs generally form a chevron.

Further, even if the bed does not press against the body and moves so as not to shift its position as described above, the effect cannot be exhibited unless the mats or sheets placed thereon can follow the movement. So, about mats and sheets,
The back part that adheres to the backrest of the bed and the waist part that adheres to the waist are separated, and the space between them is connected by an elastic member, so that the waist of the bed follows the movement of moving forward greatly. .

[0010]

The bed according to the present invention uses the optimal mat and sheets to be combined with the bed,
When raising the backrest and raising the patient, the backrest rises down so that the patient's clothes do not pull up and give a feeling of hanging, and the waist moves greatly forward, so it can be pushed from the back The hips move forward and I do not feel any oppression. Also, there is no displacement of the body with respect to the bed.

[0011] Therefore, the patient lying down can be awakened without pain, and the patient himself feels like to wake up frequently, and the position of the body does not change for the caregiver no matter how many times the patient wakes up. Because there is no need to pull and change the position of a heavy patient, it is tempting to raise it as many times as possible, and as a result, the patient can maintain the posture often raised, maintaining lifestyle and functioning Useful for recovery and preventing bedsores.

[0012]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below in detail with reference to the drawings. FIG. 1 corresponds to a state in which a patient lies down while lying on the top surface of a bed. The bed surface is divided into three backrest parts, four waist parts, and five foot parts, and each is connected by twelve waist gap-filled sheets and ten slide fulcrums.

FIG. 2 shows a state in which the backrest is raised. A series of operations when the backrest is raised will be described with reference to FIG. When the lower end of the 6-back upper link is pulled toward the motor side by the 2-back upper motor, the upper end of the 6-back upper link pushes up the 3 backrest portion. At this time, the three backrests are 1
It rotates upward around the five fulcrums A. At this time, since the 15 fulcrums A are below the three backrests, the lower ends of the three backrests pivot downward.

At the same time, the other end of the interlocking link, which is pivotally supported by the upper back link which is pivoted upward, is pivotally supported at the other end by the lower back link. Rotate the link downward. At this time, the eight waist forward link is pivotally supported by the four waists, and moves the four waists downward.

At this time, the four waist portions and the five foot portions are rotatably connected to each other at ten slide fulcrums, and the ten slide fulcrums move in the downward direction while sliding on nine slide axes. Therefore, the five feet also move in the direction of the feet. The other end of the 5 feet is supported by the 11 feet forward link,
It pivots around the 17 fulcrum C and moves downward in the direction of the feet.

Therefore, when the three backrests are raised, the three backrests sink downward so that the mats, sheets and clothes in contact with the backrest surface are not moved upward, so that the neck hanging phenomenon due to the clothes occurs. Absent.

At the same time, the four waist parts move downward, so
The upper body of the patient is not pushed from the back and pressed.

Since the four waist portions and the five foot portions are substantially mountain-shaped, a natural and comfortable sitting position can be maintained.

In the gap between the backrest portion and the waist portion, a 12 waist gap filling sheet is elastically wound and wound around a take-up roller, and a mat, a sheet, a futon, a human body, etc. It also prevents falling and pinching, and follows the change in the gap between the three backrests and the four waist due to the sliding of the four waist.

Similarly, in the gap between the five feet and the end of the bed, a 12 waist gap filling sheet is elastically wound around a 14 take-up roller and stretched. It prevents the futon, the human body, etc. from falling and being pinched, and follows changes in the gap between the five feet and the end of the bed caused by sliding of the five feet.

FIG. 3 shows sheets and mats suitable for a bed having the above functions and structures. FIG. 3A shows the sheets and the mat in a state where the bed surface is horizontal. The upper part of the three backrests of the bed is configured as an 18 sheet upper part and the upper part of a 21 mat, and the part located at the upper part of the four waist and five feet of the bed is one part.
A 9 sheet lower part and a 22 mat lower part are formed, and the upper part and the lower part are elastically connected by a 20 sheet connecting member and a 23 mat connecting member, respectively.

Therefore, even if the three backrests are raised as shown in FIG. 3 (B) and the gap between the three backrests and the four waist is widened, the mat and the bed surface do not slip, and the respective connecting members are not slipped. Can be followed by elastic deformation. Accordingly, the sheets and the mat placed on the bed surface can perform the same movement as the movement of the bed surface, and the effect is not reduced.

[0023]

As described above, the bed according to the present invention is such that the backrest sinks downward when the patient is raised by raising the backrest by using the optimum mat and sheets combined therewith. Because it wakes up, without pulling the patient's clothes upward and giving a feeling of hanging,
Since the waist moves forward greatly, even if pushed from the back, the waist moves forward and does not feel a feeling of oppression. Also, there is no displacement of the body with respect to the bed.

Therefore, the patient lying down can be woken up without any pain, and the patient himself feels like to wake up frequently, and the position of the body does not change for the caregiver no matter how many times the patient wakes up. Because there is no need to pull and change the position of a heavy patient, it is tempting to raise it as many times as possible, and as a result, the patient can maintain the posture often raised, maintaining lifestyle and functioning Useful for recovery and preventing bedsores.
