Abstract

Disclosed is an anesthetic gas distribution device capable of being easily adjusted to conform to various conditions of a sample. An anesthetic gas distribution device according to an embodiment of the present invention includes a manifold block including a main block and one or more sub-blocks coupled to one side or two opposite sides of the main block so as to be separable in a first direction, the manifold block being configured to be supplied with the gas from the outside, and supply nozzles connected to the manifold block in a second direction perpendicular to the first direction and configured to supply the gas to the sample.

First claim

What is claimed is:

1 . An anesthetic gas distribution device, which is configured to supply gas to a sample, comprising:
a manifold block comprising a main block and at least one sub-block coupled to one side or two opposite sides of the main block so as to be separable in a first direction, the manifold block being configured to be supplied with the gas from outside; supply nozzles connected to the manifold block in a second direction perpendicular to the first direction and configured to supply the gas to the sample; a first passageway portion and a second passageway portion respectively provided in the main block and the at least one sub-block such that the gas supplied from the outside passes through the first passageway portion and the second passageway portion; and a sliding unit provided in the second passageway portion of the at least one sub-block and configured to move in the first direction in the at least one sub-block along the second passageway portion of the at least one sub-block, a first connection unit configured to connect the first passageway portion of the main block and the sliding unit in the at least one sub-block; and a second connection unit configured to connect neighboring sliding units in a plurality of the at least one sub-block, wherein the supply nozzles comprise:
a first supply nozzle coupled to the first passageway portion of the main block; and
a second supply nozzle coupled to the sliding unit and configured to move together with the sliding unit when the sliding unit moves in the first direction, and
wherein the sliding unit is movable in a space between the first connection unit and the second connection unit based on the first direction or a space between second connection units adjacent to each other in the first direction.

2 . The anesthetic gas distribution device of claim 1 , wherein the first connection unit comprises:
a first flow tube provided in the first connection unit and inserted into the sliding unit; an insertion portion protruding in a diameter direction from an outer periphery of the first flow tube and coupled to the first passageway portion of the main block in the first direction; and a first enlarged diameter portion having a larger diameter than a diameter of the first flow tube and a diameter of the insertion portion, connected to the insertion portion, and protruding from the outer periphery of the first flow tube, and wherein the first enlarged diameter portion is seated in a first groove portion formed in the second passageway portion of the at least one sub-block.

3 . The anesthetic gas distribution device of claim 1 , wherein the second connection unit comprises:
a second flow tube provided in the second connection unit and configured to connect the neighboring sliding units; and a second enlarged diameter portion having a larger diameter than the second flow tube and protruding from an outer periphery of the second flow tube, and wherein the second enlarged diameter portion is seated in a first groove portion formed in the second passageway portion of the at least one sub-block.

4 . The anesthetic gas distribution device of claim 1 , wherein the second passageway portion of the at least one sub-block further comprises a second groove portion formed at a lateral side of the at least one sub-block based on the second direction and configured to define a space in which the second supply nozzle moves in the first direction.

5 . The anesthetic gas distribution device of claim 1 , wherein the main block further comprises a gas inlet port connected to the first passageway portion of the main block and configured to receive the gas from the outside.

6 . The anesthetic gas distribution device of claim 1 , further comprising:
a first residual gas flow portion and a second residual gas flow portion respectively provided in the main block and the at least one sub-block and disposed at positions spaced apart from the first passageway portion and the second passageway portion in the second direction, wherein the gas, which remains after a process of supplying the gas to the sample, flows through the first residual gas flow portion and the second residual gas flow portion.

7 . The anesthetic gas distribution device of claim 6 , further comprising:
intake ports respectively provided in the main block and the at least one sub-block and connected to the first residual gas flow portion and the second residual gas flow portion in the second direction, wherein the gas, which remains after the process of supplying the gas to the sample, flows into the first residual gas flow portion and the second residual gas flow portion through the intake ports.

8 . The anesthetic gas distribution device of claim 6 , further comprising:
a third connection unit configured to connect the first residual gas flow portion of the main block and the second residual gas flow portion of the at least one sub-block.

9 . The anesthetic gas distribution device of claim 8 , wherein the third connection unit comprises a third flow tube provided in the third connection unit, and the gas, which is introduced into the second residual gas flow portion of the at least one sub-block, flows through the third flow tube.

10 . The anesthetic gas distribution device of claim 6 , wherein the main block further comprises a gas outlet port connected to the first residual gas flow portion of the main block and configured to discharge the gas, which flows in the first residual gas flow portion of the main block and the second residual gas flow portion of the at least one sub-block, to the outside.

11 . The anesthetic gas distribution device of claim 6 , further comprising:
a second cover coupled to the second residual gas flow portion of the sub-block positioned at an outermost position from the main block.

12 . The anesthetic gas distribution device of claim 1 , further comprising:
a first cover coupled to the second passageway portion of the at least one sub-block positioned at an outermost position from the main block.

13 . The anesthetic gas distribution device of claim 1 , further comprising:
sealing members coupled to sealing member accommodation portions provided on the sliding unit and configured to seal a gap between the first connection unit and the sliding unit and a gap between the second connection unit and the sliding unit.
