Abstract
Abstract A portable, multipurpose apparatus for anaesthesia and respiratory reanimation provided with means, for the vaporization of anaesthetic liquids and for the administration of anaesthetics and respiratory reanimation. The assembly comprises T-pieces, with a switch, for the connecting of a self-inflating bag or of a respiratory bellows ahead of the vaporizer and for connection of a respiratory bag, downstream the vaporizer; a third shutting-off T-piece, with a switch is provided with a self-occluding valve or with a soda lime canister and a self-occluding valve, united by corrugated tubes, with connections for a closed-circuit respirator bag or for a respirator for closed circuit. The portable apparatus has the pieces of the assembly and of the first administering circuit mounted on the upper cross-bar of a supporting frame for the table; in a wall version, with a lower support for the new circuit, the frame can be fixed detachably to a bar fastened in the wall.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
181 words
An apparatus for administering an anaesthetic and for respiratory reanimation comprising: a support; a gas-mixing assembly mounted on said support and provided with an inlet and an outlet and a main flow path therebetween for at least one gas adapted to be administered to a patient; at least two T-fittings detachably connected in series with one another and to said assembly on said support, each of said fittings having a main flow path connected in series with one another and with the main flow path of said assembly, a branch extending laterally from the respective main flow paths of said fittings and respective selectively operable closure members for selectively effecting communication between the respective branch and main flow path; a vaporizer detachably connected between said fittings on said support and in series with the main flow paths thereof; a shutoff fitting detachably connected to the main flow path of said T-fittings downstream thereof and provided with a selectively operable flow-blocking closure member; an administering mask system detachably connected to said shutoff fitting, and respective inflatable bags detachably connectable to said branches.
Claim 2
Independent Claim
181 words
An apparatus for administering an anaesthetic and for respiratory reanimation comprising: a support; a gas-mixing assembly mounted on said support and provided with an inlet and an outlet and a main flow path therebetween for at least one gas adapted to be administered to a patient; at least two T-fittings detachably connected in series with one another and to said assembly on said support, each of said fittings having a main flow path connected in series with one another and with the main flow path of said assembly, a branch extending laterally from the respective main flow paths of said fittings and respective selectively operable closure members for selectively effecting communication between the respective branch and main flow path; a vaporizer detachably connected between said fittings on said support and in series with the main flow paths thereof; a shutoff fitting detachably connected to the main flow path of said T-fittings downstream thereof and provided with a selectively operable flow-blocking closure member; an administering mask system detachably connected to said shutoff fitting, and respective inflatable bags detachably connectable to said branches.
Claim 3
Dependent Claim
91 words
The apparatus defined in claim 1 wherein each of said fittings comprises a cylindrical body defining the main flow paths thereof and provided with formations at least at one end for detachable connection to other elements of the apparatus, and said closure members each include a cylindrical sleeve rotatably received in the respective body and provided with a lateral opening, and a lever projecting from the respective body and affixed to the respective sleeve for rotating same about its axis, said bodies each having an arcuate slot receiving the respective lever.
Claim 4
Dependent Claim
90 words
The apparatus defined in claim 1 wherein said support comprisEs a base, a pair of columns spaced apart and extending upwardly from said base, and a crossbar receiving elements of said apparatus including said assembly, said fittings and said vaporizer, said gas-mixing assembly including: a mixing block mounted on said crossbar; an oxygen flow meter extending between said base and said block; a nitrogen protoxide flow meter extending between said base and said block; and an emergency-oxygen duct provided with a valve and extending between said base and said block.
Claim 5
Dependent Claim
33 words
The apparatus defined in claim 1 wherein said support comprises a frame adapted to be affixed to a wall and means for mounting said assembly, said fittings and said vaporizer on said frame.
Claim 6
Dependent Claim
68 words
The apparatus defined in claim 1 wherein said administering mask system comprises a single elongated conduit detachably connected to said shutoff fitting at one end thereof and a mask having an exhalation port to the atmosphere attached at the other end of said elongated conduit, whereby the closure members are operated to communicate the branches of the T-fittings with the main flow path providing for an open system.
Claim 7
Dependent Claim
42 words
The apparatus defined in claim 1 wherein said administering mask system comprises a closed loop breathing circuit whereby the closure members are operated to prevent communication between the branches of the T-fittings and the main flow path providing for a closed system.
