Filling system for an anesthetic dispenser

Abstract

A filling system for an anesthetic dispenser has a coding feature. An opening ( 29 ) is provided at a connection piece top side ( 10 ) of an outlet connection piece ( 8 ) of a bottle adapter ( 100 ). The opening ( 29 ) is connected to the lateral slots ( 9 ) and a length of rods on an inner wall of the filling connection piece is dimensioned such that they mesh both with the slots ( 9 ) and with the opening ( 29 ).

         1 . A filling system for an anesthetic dispenser, the filling system comprising:
 an anesthetic evaporator;   a bottle adapter having an adapter neck and an outlet connection piece comprising at least one slot running in the radial direction and a central opening connected to said at least one slot;   a filling device at the anesthetic evaporator with a filling connection piece for adapting the adapter neck; and   at least one rod fastened to the filling connection piece, said at last one rod extending radially from a center and meshing with said central opening.   
     
     
         2 . A filling system in accordance with  claim 1 , wherein:
 said at least one rod comprises a rod spoked wheel configuration;   said at least one slot comprises a slot spoked wheel configuration; and   said flange is designed corresponding to said central opening.   
     
     
         3 . A filling system in accordance with  claim 1 , wherein said central opening comprises an extension of said at least one slot or slots. 
     
     
         4 . A filling system in accordance with  claim 2 , wherein:
 said rod spoked wheel configuration comprises said at least one rod, additional rods and said flange as a central punctiform portion or a virtual connection point, at which said rods converge in a center of said filling connection piece.   
     
     
         5 . A filling system in accordance with  claim 2 , wherein said central opening comprises an extension of said slot. 
     
     
         6 . A filling system in accordance with  claim 5 , wherein:
 said rod spoked wheel configuration comprises said at least one rod, additional rods and said flange as a central punctiform portion or a virtual connection point, at which said rods converge in a center of said filling connection piece.   
     
     
         7 . A filling system for an anesthetic dispenser, the filling system comprising:
 an anesthetic evaporator;   a bottle adapter having an adapter neck and an outlet connection piece comprising a slot structure with a central opening and a slot running in the radial direction forming a continuation of said opening;   a filling device at the anesthetic evaporator with a filling connection piece defining a neck adapter mount; and   a rod structure fastened to the filling connection piece, said rod structure including a rod extending radially from a center, said rod extending in an axial direction into said slot running in the radial direction as said outlet connection piece is inserted into said filling connection piece with said rod structure not being blocked by said central opening.   
     
     
         8 . A filling system in accordance with  claim 7 , wherein:
 said rod structure comprises said rod and a central flange;   said central opening comprises an extension of said slot; and   said rod extends in an axial direction into said slot running in the radial direction and said flange extends in an axial direction into said central opening as said outlet connection piece is inserted into said filling connection piece.   
     
     
         9 . A filling system in accordance with  claim 8 , wherein:
 said rod structure comprises a spoked wheel rod configuration including said central flange, said rod and additional rods extending radially from said central flange;   said slots comprise a spoked wheel slot configuration including said central opening, said slot and additional slots extending radially from said central opening at said outlet connection piece of said bottle adapter; and   said spoked wheel rod configuration is complementary to said spoked wheel slot configuration with said flange corresponding to said central opening.   
     
     
         10 . A filling system in accordance with  claim 9 , wherein:
 said flange is a central punctiform portion or a virtual connection point, at which said rods converge in a center of said filling connection piece.   
     
     
         11 . A filling system for an anesthetic dispenser, the filling system comprising:
 an anesthetic evaporator;   a bottle anesthetic reservoir;   a bottle adapter attached to said bottle anesthetic reservoir, said bottle adapter comprising an adapter neck and an outlet connection piece comprising a slot structure with a central opening and a slot running in a radial direction forming a continuation of said opening;   a filling device at the anesthetic evaporator with a filling connection piece defining a neck adapter mount; and   a rod structure fastened to the filling connection piece, said rod structure including a rod extending radially from a central flange center, said rod extending in an axial direction into said slot running in the radial direction as said outlet connection piece is inserted into said filling connection piece with said rod structure not being blocked by said slot structure.   
     
     
         12 . A filling system in accordance with  claim 11 , wherein:
 said central opening comprises an extension of said slot; and   said rod extends in an axial direction into said slot running in the radial direction and said flange extends in an axial direction into said central opening as said outlet connection piece is inserted into said filling connection piece.   
     
     
         13 . A filling system in accordance with  claim 12 , wherein:
 said rod structure comprises a spoked wheel rod configuration including said central flange, said rod and additional rods extending radially from said central flange;   said slot structure comprise a spoked wheel slot configuration including said central opening, said slot and additional slots extending radially from said central opening at said outlet connection piece of said bottle adapter; and   said spoked wheel rod configuration is complementary to said spoked wheel slot configuration with said flange corresponding to said central opening.   
     
     
         14 . A filling system in accordance with  claim 13 , wherein:
 said flange is a central punctiform portion or a virtual connection point, at which said rods converge in a center of said filling connection piece.
