The invention discloses an ergonomics functional
bed for old and weak people, comprising a
bed body, a matrix gas compression and propulsion
system, a telecommunication
warning system, a
bed board overturning mechanism and a leg bending mechanism, wherein, the matrix gas compression propulsion
system is provided with a plurality of air bags and a plurality of pressure sensors; the air bags are positioned below the bed board; the pressure sensors are distributed between the bed board and the air bags in a matrix manner; and the telecommunication
warning system comprises a sound acquisition terminal, an
image acquisition terminal and a 3G communication module. The functional bed can track and scan the condition of a person
lying in bed in real time, can lead the person
lying in bed to actively perform
direct communication with doctors and family to report the state of illness and the current condition, can lead the off-site family and the doctors to know about the condition, thus increasing the degree of
life support; and meanwhile, the functional bed can perform
aeration and deflation for the air bags to the designated part of a bed surface according to the demand of the person
