Description
Technical field
The present invention relates to bionic field, in particular to a kind of bionical body position adjusting bed based on multiple spot forming principle.
Background technique
Currently, in social groups' structure, autonomic activities it is difficult or can not the groups of autonomic activities occupy quite a few ratio
Example, below by taking ultrasonic examination scene and old man's daily nursing as an example:
Ultrasonic examination is a kind of modern regular medication means, patient compliance doctor stands up during the inspection process, turns on one's side,
It the operation such as rolls, bend one's legs, generally for facilitating doctor preferably to check, patient being needed to carry out the direction of postural change and amplitude
Subtle adjustment carries out meeting inspection for seldom carrying out group, old group or some disability groups of ultrasonic examination
The postural change that doctor requires generally requires the longer time.Existing ultrasonic examination bed board is only the narrow bed board of one side, Bing Ren
Turned over, rolled above etc. activities can not specific direction, amplitude, with obstacle, self the action obstacle etc. of doctor in communication
It all will affect inspection efficiency.
For the statistical data in the end of the year 2016,60 years old Chinese or more elderly population accounting 16.7%；It should in the year two thousand forty
Group's population will break through 3.97 hundred million, estimate according to expert, and Aging Problem will influence Chinese future home structure from many aspects
Transformation, the nursing problem of the elderly is very prominent.Sufferer, which is lain, to be usually required periodically to complete left-right rollover on one's sick bed, turn over completely
The positions such as body, pitch require the hospital bed disease to prevent bedsore, and existing air cushion hospital bed has a single function, only imitative bedsore function
Energy.Other hospital beds with postural change device mostly use the mode of rotation Compound mattress to carry out postural change currently on the market,
Although this mode implements simply, its comfort and its poor with the harmony of human body.
Postural change bed accessory is produced for reply above situation, by the current postural change bed accessory device of driving method in city
Two classes are broadly divided on:
One kind is manual, simple function, the mobile hospital bed for overturning class, and this kind of hospital bed is used primarily in the ICU disease of general hospital
Room, this kind of hospital bed can complete simple lift by traditional mechanical transmission mechanism manipulation backboard, leg plate by the driving of manpower
Dorsiflex leg-shaped state does not roll, turning body function；
It is another kind of be it is electric hospital bed, this kind of hospital bed can be realized according to simple control system with being driven by electricity each execution
Mechanism, with electric power instead of manpower, the original design intention of this kind of hospital bed is the labor intensity for mitigating operator.
Above two hospital bed is all made of the postural change scheme of bed board turnover type, and scheme is both advantageous and disadvantageous, with simply
Structure, which reaches functional requirement, is worth affirmative, but the said goods have ignored man-machine device to the comfort of human body and imitating for equipment itself
Natural disposition, as the equipment with direct body contact, the mode that equipment reaches expectation function should accomplish the row of imitative normal human as far as possible
It is characterized, such as executing agency when assisting patient to turn over is not bed board but the device of apery hand, while turn
It bends one's legs, appropriate buttocks is had an effect during sitting up.
Summary of the invention
The present invention is in order to solve in above-mentioned background technique, existing bed body comfort and its poor with the harmony of human body, lacks
