Description
Technical field
The present invention relates to a kind of bed body position signal acquisition devices, and the invention further relates to one kind to have the bed body position signal
The waist cervical vertebra of acquisition device goes up and down supporting pad.
Background technique
The major function of bed body position signal acquisition device be by lie on one's side during sleep quality, two kinds of differences of lying on the back
The measurement of position provides control signal for corollary equipment.Existing sleep position measurement device shares the disadvantage is that largely all
It needs to wear on human body, the object of a specific device or special material production is either pasted, although these method energy
It is enough that required operation signal is accurately provided, but part user can feel not convenient enough.Some sleeping position acquisitions, detection system
Although not needing to wear or be attached on human body, but structure is complicated, cost is high, not enough precisely and real for different degrees of presence
The disadvantages of poor with property, so that the production and popularization to Related product exert a certain influence.
Domestic Waist disc patient is being increasing at present, and lying up for this patient is that one kind simply has
The method of rehabilitation of effect.In order to guarantee that limbs and vertebra are loosened during bed, strictly prevent waist and vacant state occur,
Professional proposes this claimed below: when lying low, the pillow of pillow should be reduced, and pillow should increase when lying on one's side.Except this
Except, it also requires respectively to pad a height suitable pad when lying low below waist and knee, removes two pads when lying on one's side.It realizes
It is such to require more troublesome, although can accomplish substantially under waking state, lie low in sleep procedure, the position lain on one's side is handed over
For being difficult to realize in the process.So design pillow when one kind lies low reduces automatically, at the same under waist, pad is automatic at one's knees increases；Side
Pillow increases automatically when sleeping, under waist, pads the automation equipment reduced automatically at one's knees as current urgent problem to be solved.
