Abstract

PROBLEM TO BE SOLVED: To provide a mat device by which a patient or a bed-ridden aged person can freely and safely roll in the left and right directions by himself/ herself without the need of the help of others. SOLUTION: This device is provided with a fixed base and upper movable bases capable of inclining the body in left, right and inner side directions mounted in two columns on the left and right across a center line. The respective upper movable bases are provided with a warm gear mechanism on the back surface and the warm gear mechanism is provided with a motor-driven switch mechanism. When the patient on a mat wants to lie down on the right side, a motor-driven switch is operated and the movable base on a left inner side is inclined to the right. The movable base at a left wing (left outer side) is inclined to the right further. Simultaneously, the movable base on a right outer side is inclined to the left (that is to the inner side) and lying down by himself/herself is made possible.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a patient or a bedridden elderly who can take a supine posture by himself / herself and a lying posture in which the patient or a bedridden elderly person can freely roll over to the left or right without requiring the care of another person. The present invention relates to a rollable mat device that enables comfortable lying down without fatigue even if the posture is taken for a long time.

[0002]

2. Description of the Related Art Preventing bedsores of bedridden elderly people and severely ill patients who are unable to get up, an air mattress that makes it easy to get up, a bed with a structure that allows the upper body to be raised for convenient eating and reading, back pain and back pain Various types of mattresses and the like that have been devised to suppress noise are known. For example, a bed (Japanese Patent Laid-Open No. 8-308885) which facilitates a standing operation with the soles of the feet touching the floor, and an air mattress which jets ozone and alkaline air having sterilization, deodorization, and drying properties (Japanese Patent Laid-Open No. No. 10-5290), a vertically movable bed which has a plurality of airbags in the vertical direction and is capable of adjusting the height and hardness by appropriately injecting air into an arbitrary airbag (JP-A-9-22498).
No. 2), an air mattress capable of arbitrarily changing the air ejection point (Japanese Patent Laid-Open No. 2000-37264), and distributing body pressure by controlling the pressure for each of a plurality of air tubes arranged horizontally. There are many air mattresses (JP-A-11-206513) for preventing bedsores.

[0003] However, all of them are for completely bedridden or elderly people, or for getting up or half-sloping up and down for eating and reading, etc. There are no beds or mats that can change posture. If it can be rolled to the left or right for one inch without the help of a caregiver or attendant, it is possible to add various kinds of use, and it can also prevent bedsores and alleviate back and lower back pain.

[0004]

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and enables a patient or a bedridden elderly person to take a supine position on his / her own right or left without any need for the care of another person. It was designed to be able to freely lie down and take a lying position, and even if the lying position is taken for a long time, there is no fatigue, it enables easy lying down, and it is designed not to rotate with the lying down operation An object of the present invention is to provide a rollable mat device.

[0005]

SUMMARY OF THE INVENTION The present invention provides a bottom fixed base, a right upper movable base and a left inner movable base on the upper surface of the fixed base which are capable of tilting the body in both left and right directions. It has an inner movable base, and a right-wing movable base and a left-wing movable base that can be bent inward on both wings. Each movable base has a row of hydraulically-operated worm gear mechanisms on its back surface. The worm gear mechanism has a mechanism for sliding up and down to tilt each movable base, and an electric switch mechanism for electrically operating the up and down movement of each movable base.

When a patient lying on the mat wants to lie down on the right flank, the electric switch is actuated, and the worm gear mechanism on the left inside with the center line interposed therebetween is slid upward to move the left inside movable. Tilt the base to the right. Further, the movable base of the left wing (left outer side) is further inclined rightward to support the left shoulder of the patient. The inclination angle at this time is 10 to 30% greater than the inclination angle of the left inner movable base. At the same time, the worm gear mechanism of the right wing (right outside) slides upward to move the right outside movable base to the left with an inclination angle of 5 to 30% of the inclination angle of the left inside movable base (ie, A first aspect of the present invention is a rollable mat device that is designed to be tilted (inward) to stabilize the posture of a patient and to be able to lie down on its own.

In another aspect of the present invention, the upper movable base row of the above-mentioned rollable mat device is further divided into an upper body part and a lower body part, and the lower body inner movable base is an upper body inner movable base. Is inclined inward with an inclination angle 5 to 30% larger than the inclination angle. In other words, the lower body, especially the feet, has a stronger inclination angle than the upper body than the upper body, so that the lying posture of the lying patient becomes more stable, and the patient can spend more comfortably and comfortably. This is a rollable mat device capable of lying down on its own (second embodiment of the present invention).
