Description

  The present invention relates to a dissecting table provided with an air purification device for preventing health damage to an autopsy person due to formaldehyde and other harmful gases emitted from an autopsy sample placed on the top plate of the dissecting table.

In an anatomical practice in a university medical school or dentistry, formaldehyde generated from an autopsy specimen in which formalin is injected into the body or an autopsy specimen immersed in formalin may impair the health of an autopsy person (practitioner). Therefore, conventionally, air in the anatomy room is exhausted to the outside by a blower through a ventilation duct, and fresh air is introduced into the room to reduce the concentration of formaldehyde in the laboratory, and formaldehyde is adsorbed in the anatomy room. Alternatively, safety measures such as a purification method in which an air purification device that oxidizes and decomposes is installed to reduce formaldehyde in the room, or a combined method in which the ventilation method and the purification method are used in combination have been adopted.
Some inventions have been made for these safety measures.
