The end of the section remote from the barrier is perforated to permit the anesthetic vapor to pass therethrough and a sealable filling means is in the top for introduction of the anesthetic into the receiving chamber. The dispenser is preferably combined with a particularly described stand which is adapted for engagement with a surgical table. The entire device is primarily intended for use on small animals.

An anesthetic dispenser comprising a body of generally cylindrical shape and having two ends, a top on one of said ends, a barrier intermediate said ends and dividing said dispenser into a receiving chamber and a dispensing section,

valve means adapted to control the flow of said anesthetic from said receiving chamber to said dispensing section comprising a generally cylindrical opening in said barrier, a stem in said opening, said stem having a wide portion and a narrow portion, said wide portion being at least of substantially the same size as said opening and said narrow portion being substantially smaller than said opening, means for moving said stem axially of said opening into a first position and a second position, said wide portion blocking said opening when said stem is in said first position and apart from said opening when said stem is in said second position, whereby anesthetic is permitted to flow from said chamber into said section when said stem is in said second position,
the end of said section remote from said barrier being perforated to permit said anesthetic vapor to pass therethrough, said top including an opening having a sealable filling means therein for introduction of said anesthetic into said receiving chamber, diametrically opposed support means extending radially of said body, a stand comprising two substantially parallel, vertical side portions, said side portions being spaced apart horizontally and connected by a web extending therebetween adjacent the bottom end of said stand, a dispenser slot in each side portion adjacent the upper end of said stand, said slots being complementary to said support means, said support means slidably located in said dispenser slots whereby said dispenser is suspended from said stand.
