Description

  The present invention relates to a mattress with a ventilation function capable of efficiently carrying out heat and moisture confined in the mattress to the outside.

  Conventional mattresses for preventing bedsores, such as air mattresses and urethane foam mattresses, can achieve a body pressure dispersion effect by widely supporting the body, but since the body is supported by the surface, sweating due to an increase in body temperature It has been pointed out that the user may feel uncomfortable due to stuffiness caused by the above.

  In order to solve such a problem, for example, Patent Document 1 discloses that the outer periphery of a cushion portion formed of an air cell, a resin foam, or the like is hermetically sealed with a covering cloth such as a base sheet or a cover sheet. Ventilation air for venting exhaust air into the mattress on the side opposite to the exhaust hole with a cushion part in between, and vent holes on the side of the covering fabric covering the outer periphery A mattress provided with blowing means is disclosed.

  According to this mattress, the air for ventilation sent into the mattress takes in heat and moisture in the mattress while it flows between the air cells in the mattress and carries it out of the mattress. It is said that an increase in body temperature at the contact area with the body can be effectively suppressed, and sweating and stuffiness due to an increase in body temperature can be prevented.
