Medical posture retainer
The present invention is a medical posture retainer having a mat and a core member. The mat includes an airtight bag and a cushion layer. The airtight bag is a cover of the mat and has a gas barrier property. An exhaust valve for deflation is attached to the bag. The cushion layer is formed of particles in the bag. The core member includes a plate-like support that is attached to a side face of the hag to keep a certain rise height, and a stopper that is attached to the upper face and the lower face of the airtight bag to restrict the rise height. The core member is attached before deflation of the bag so as to impart a shape necessary for receiving a specific part of a human body.
1. A medical posture retainer comprising a mat and a core member, wherein
the mat comprises an airtight bag extending in longitudinal and width directions and a cushion layer,
the airtight bag, as a cover of the mat supporting a human body and retaining a posture of the human body, has a gas barrier property and is formed with an air supply-exhaust hole for deflating the airtight bag at the time of use of the medical posture retainer for volume reduction of the airtight bag and for allowing the volume-reduced airtight bag to suck air after the use,
the cushion layer comprises strata of particles to fill the airtight bag and to be set by deflation of the airtight bag,
the core member comprises a support plate and a stopper, the support plate being oriented substantially perpendicularly with respect to both the longitudinal and width directions of the airtight bag and being attached to either an inner side face or an outer side face of the airtight bag, the support plate having rigidity so as to keep a predetermined rise height of the airtight bag at a part supporting a neck of the human body, the stopper being attached to an upper face and a lower face of the airtight bag for restricting the rise height of the mat at a part supporting a head of the human body,
the airtight bag has a rectangular upper face member joined to a rectangular lower face member at a joint, and
the support plate bridges over the joint between the face members.
