Embodiment 1
Traditional physiological parameter acquisition all relies on greatly various intrusive mood equipment, and life is measured by way of stickup or clip
Reason parameter, designer it has been investigated that, this acquisition mode can cause psychological and physiologically burden to person under inspection so that survey
May there is error in amount result, and traditional physiological parameter acquisition needs person to be detected to specific with the actual conditions of detected person
Environment, such as ground such as hospital, MEC carries out, and human body physiological parameter frequency acquisition is greatly limit, if one kind can be researched and developed
Use, and in the case where people's normal life is not influenceed, often human body physiological parameter can be acquired suitable for family, company
Harvester 400, above mentioned problem, and more conducively popularization and application can be effectively improved.
Based on this, as shown in figure 1, the embodiment of the invention discloses a kind of physiological parameter acquisition device 400, being arranged on carrier
On harvester 400 can be for various, set-up mode, position also have various, as long as can realize that the human body being pointed in carrier is given birth to
The collection of parameter is managed, carrier can be used alone, it is also possible to be embedded into bed, mattress, chaise longue, seat and other items and use,
As long as human body can be accommodated, the harvester 400 being arranged on carrier can be one or more, as long as entering carrier in human body
Afterwards, the physiological parameter that needed by human body monitors position can be obtained, for example：When carrier is used alone, 400 need of harvester
Just to human chest or trunk；When being used after carrier insertion mattress, in order to realize the monitoring to human chest parameter,
By harvester 400 be distributed in mattress accommodate human body after, mattress just to body chest positions at, for example：In order to realize monitoring
Accuracy, mattress just at human chest or trunk position can be set multiple harvesters 400, as shown in Figure 1.
By above-mentioned, carrier not only can be used alone, and can be placed in mattress lower section, mattress inside etc. and carry out
Use.
After being arranged such, human body need to only enter the carrier for being provided with harvester 400, and harvester 400 just can be to user
Physiological parameter in the state of zero load (during such as sleep, rest) is monitored, and family expenses is very suitable for, separately, for the ease of follow-up
, preferably with a processing unit be connected harvester 400 by treatment.
In order to ensure the accuracy of the monitoring of harvester 400, in the embodiment of the present invention, the structure to harvester 400 is entered
Ingehious design is gone, after being allowed to be arranged on carrier, can effectively monitor the physiological parameter of human body, can not have been damaged easily again
It is bad.
