Abstract: 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.

Abstract: A medical supporting fixing device having a yaw angle fine adjustment plate (6) and/or a tilt angle fine adjustment plate (8) interposed between a stage (2) and a supporting fixing means (4) for supporting and fixing a predetermined part of a human body. The yaw angle fine adjustment plate (6) and/or the tilt angle fine adjustment plate (8) are mounted so as to be rotatable over a predetermined angular range about required rotation center axes (22, 48). A yaw angle fine adjustment plate drive mechanism (16) and/or a tilt angle fine adjustment plate drive mechanism (54) including input members (28, 72) and transmission means (36, 38, 42, 74, 80, 82, 84, 86) are disposed with respect to the yaw angle fine adjustment plate (6) and/or the tilt angle fine adjustment plate (8).

Abstract: The present invention relates to a means for retaining stably a posture of a subject or a patient during a medical practice, namely, a medical posture retainer having a mat 1 and a core member. The mat 1 is composed of an airtight bag 2 and a cushion layer 3. The airtight bag 2 is a cover of the mat 1 supporting the human body and retaining the posture. The airtight bag 2 has a gas barrier property, and an exhaust valve for deflation is attached to the airtight bag 2. The cushion layer 3 is formed of strata of particles P filled in the airtight bag 2. The core member includes a plate-like support 4 that is attached to a (inner or outer) side face of the airtight bag 2 to keep a certain rise height of the airtight bag 2, and a stopper 6 that is attached to the upper face and the lower face of the airtight bag 2 so as to restrict the rise height of the airtight bag 2.
