To establish a method of preserving cord having high effect of preventing corruption progression considering the internal structure of the human body.SOLUTION: A syringe is filled with a liquid intracorporeal preservative to be injected into the body, which contains amino acids extracted from cereals. Also, a body surface preservative prepared by blending a seaweed-derived gel and glycerin to the same body preservative is applied to the body parts of the body and body of the body. Subsequently, with the corpse lying on its back, the lower jaw is turned upward, thereby opening the trachea from the nasal cavity of the same body. Furthermore, a small diameter tube is inserted from the nasal cavity of the body whose lower jaw faces upward, while holding one end of the tube out of the body of the body while passing the other end of the tube through the pharynx inside the body to the larynx Reach it. One end of the tube which is kept outside the body is attached to the tip of a syringe filled with a preservative for the body and made to communicate. Then, by pushing the pusher of the syringe, the antiseptic for the body is injected into the body.BACKGROUND OF THE INVENTION【課題】人体の内部構造も勘案した、腐敗進行防止効果が高い遺体保存方法を確立する。【解決手段】穀物から抽出されたアミノ酸を含んで成る、遺体内部に注入される液状の体内用防腐剤を注射器に充填する。また同体内用防腐剤に対し海藻由来のゲル剤とグリセリンを配合して成る体表用防腐剤を、遺体の毛髪と遺体全身の体表部分に塗布する。続いて遺体を仰向けにした状態で下顎を上向きにすることで、同遺体の鼻腔から気管までを開通させる。さらに細径のチューブを下顎を上向きにした遺体の鼻腔から挿入し、同チューブの一端は遺体の体外に出したまま保持する一方、同チューブの他端を遺体内の咽頭を通過させて喉頭まで到達させる。体外に出したままのチューブの一端は、体内用防腐剤を充填した注射器の先端部に取付けて連通させる。そして注射器の押子を押込むことで体内用防腐剤を遺体内に注入する。【選択図】図1
