Mattress and method for controlling same

Abstract

The objective of the present invention is to provide: a mattress having a novel structure, able to rapidly decentralize a section of body pressure action of a user, and able to decrease discomfort that the user feels during an operation of switching the internal pressure of cells; and a method for controlling the mattress. The present invention is provided with: a grouping step (S2) for, on the basis of the body pressure applied to each of a plurality of cells (24), dividing the plurality of cells (24) into groups; a target internal pressure setting step (S3) for setting the target internal pressure of the cells (24) for each group divided in the grouping step (S2); and an internal pressure adjustment step (S4) for interconnecting the cells (24) in each group and adjusting the internal pressure of the cells (24) to the internal pressure set in the target internal pressure setting step (S3).

Description

technical field [0001] The present invention relates to a mattress used for a nursing bed and the like and a control method thereof. Background technique [0002] Conventionally, mattresses having a cushioning function have been used as human body support parts in nursing beds and the like, and improved sleeping comfort has been sought by elastically supporting the human body. [0003] However, when a user who has trouble turning over continues to use an ordinary mattress for a long period of time, since the reaction force of body pressure (pressure generated by the load of the human body) continuously acts on the user's local area, it may be caused by blood flow. Aggravation, etc. cause bedsores. Therefore, in order to prevent bedsores, there has been proposed a mattress that can substantially disperse the reaction force acting on the user's body pressure by changing the position where the user's body pressure acts by utilizing the pressure of the fluid. For example, Japa...

Problems solved by technology

[0004] However, in the method of adjusting the internal pressure of each unit like the mattress of Patent Document 1, even if the user's body pressure can be dispersed, it is difficult to provide the user with good sleeping comfort.

Specifically, in movable mattresses that change the body's supporting position through periodic expansion and contraction of the unit, sometimes the user may experience an uncomfortable feeling similar to seasickness due to excessive shaking on the mattress.

[0005] In addition, in the method of adjusting the internal pressure of each unit by feeding fluid into or discharging fluid from each unit, it takes time until the target internal pressure switching operation is completed, and there are irregularities in each unit during the switching operation. Does not follow the shape of the human body, causing the user to feel incongruity and discomfort

In addition, since the internal pressure switching operation takes time, there are also cases where the user changes posture during the internal pressure switching operation, and it has not been proposed that the body pressure acting part can be quickly activated without causing the user to feel uncomfortable. decentralized approach
