Toxic gas exposure preventing system for anatomic practice room

Abstract

A toxic gas exposure preventing system for an anatomic practice room is provided which not only can obtain a satisfactory toxic gas exposure preventing effect without impairing workability but also permits the use of existing dissecting tables as they are without requiring any special work such as an exhaust duct installing work. A push hood having a uniform air flow blow-off mechanism and a pull hood having an air flow suction/exhaust mechanism are disposed independently of each of the dissecting tables in such a manner that at least a portion of a uniform air flow passes in contact with a donor body on the dissecting table and is thereafter sucked into the pull hood. Further, a filter having a toxic gas adsorbing function is installed within the pull hood.

1 . A toxic gas exposure preventing system for an anatomic practice room, characterized in that a push hood having a uniform air blow-off mechanism and a pull hood having an air flow suction mechanism are disposed for each of plural dissecting tables in the anatomic practice room and independently of each of the dissecting tables in such a manner that at least a portion of a uniform air flow passes in contact with a donor body on the dissecting table an is thereafter sucked into the pull hood. 
   
   
       2 . The system of  claim 1 , wherein a filter having a toxic gas adsorbing function is installed within the pull hood. 
   
   
       3 . The system of  claim 2 , wherein the filter installed within said pull hood is positioned lower than the air flow suction mechanism and a cleaned air flow is exhausted into the room from a position lower than the dissecting table. 
   
   
       4 . The system of  claim 2  or  claim 3 , wherein a filter having a toxic gas adsorbing function is installed also within the push hood. 
   
   
       5 . The system of  claim 4 , wherein the height of an air flow blow-off opening surface of the push hood and/or the height of an air flow suction opening surface of the pull hood are (is) adjustable. 
   
   
       6 . The system of  claim 5 , wherein the height adjustment is made by a double structure of the opening surface(s) or using a shielding plate(s) disposed vertically movably in the opening surface(s). 
   
   
       7 . The system of  claim 5 , wherein the height adjustment is made by a height adjusting base portion(s) underlying the pull hood and/or the push hood. 
   
   
       8 . The system of  claim 4 , wherein the push hood and the pull hood are disposed opposedly to each other at both ends in a longitudinal direction of each of the dissecting tables. 
   
   
       9 . The system of  claim 4 , wherein one push hood is disposed at a position higher than each of the dissecting tables and a pair of pull hoods are disposed opposedly to each other at least outside both ends in a longitudinal direction of each of the dissecting tables, thereby allowing a uniform air flow to pass as a descending flow. 
   
   
       10 . The system of  claim 9 , wherein a pair of pull hoods are disposed opposedly to each other also at both ends in a transverse direction of each of the dissecting tables.
