< Topic >In order to become comfortable physical condition according to the physique of the patient, you adjust, maintain that physical condition and offer fixed possible physical condition fixture and physical condition fixed auxiliary tool.SolutionsPhysical condition fixture 1 has the irregularity aspect due to multiple projections, the hole which is located the occiput of the patient is formed, by the fact that it is located the occiput to the hole, convolution of the head is held down, free time motion of the head is inhibited. In addition, physical condition fixed auxiliary tool 4 has the irregularity aspect due to multiple projections, this touches with the irregularity aspect of physical condition fixed auxiliary tool and 4 and the irregularity aspect of physical condition fixture 1 makes physical condition fixing possible.< Choice figure >Drawing 5【課題】患者の体格に応じて安楽な体位となるように調整し、その体位を維持して固定可能な体位固定具及び体位固定補助具を提供する。【解決手段】体位固定具1は、複数の突起による凹凸面を有し、患者の後頭部を位置させる孔が形成されており、孔に後頭部を位置させることで、頭部の転動を抑え、頭部の自由な回動が抑止される。また、体位固定補助具4は、複数の突起による凹凸面を有し、体位固定補助具4の凹凸面と体位固定具1の凹凸面とを当接して体位を固定可能にする。【選択図】図5
