Connection arrangement for connecting an anaesthetic container to an anaesthetic vaporizer

A system, comprising:

• an anesthetic vaporizer with a port section;
• and
• a vaporizer container with an adapter, wherein the port section and the adapter provide together a connection device for the fluid-tight connection of the anesthetic container to the anesthetic vaporizer, wherein:
• the port section is connected to the anesthetic vaporizer;
• the adapter is connected to the anesthetic container;
• the adapter is detachably connectable to the port section;
• the port section comprises a vaporizer-side channel section;
• the adapter comprises a container-side channel section;
• with the adapter connected to the port section the two channel sections form a continuous channel, by means of which a fluidic connection is established or can be established between the anesthetic container and the anesthetic vaporizer;
• with the adapter connected to the port section an area of a surface of the port section that points towards the adapter is formed by a vaporizer-side contact profile;
• with the adapter connected to the port section an area of the surface of the adapter that points towards the port section is formed by a container-side contact profile;
• with the adapter connected to the port section the vaporizer-side contact profile and the container-side contact profile are in contact with one another without an intermediate space;
• one of the port section the vaporizer-side contact profile and the container-side contact profile has a projection and the other of the port section the vaporizer-side contact profile and the container-side contact profile has a corresponding recess;
• and
• the projection positive lockingly meshes with the recess.

A port section for an anesthetic vaporizer, wherein the port section is configured to be connected to an adapter of an anesthetic container in a fluid-tight manner, the port section comprising:

• a vaporizer-side channel section;
• and
• a vaporizer-side contact profile with a projection, wherein:
• the vaporizer-side channel section is configured to form a continuous channel together with a corresponding container-side channel section when the port section is connected to the adapter;
• the vaporizer-side contact profile is configured to form the area of the surface of the port section that points towards the adapter when the adapter is connected to the port section;
• and
• the port section is configured such that with the port section connected to the adapter the vaporizer-side contact profile is in contact with a corresponding container-side contact profile without an intermediate space and the projection positive lockingly meshes with a corresponding recess of the container-side contact profile.

An adapter for an anesthetic container wherein the adapter is configured to be detachably connected to a port section of an anesthetic vaporizer, the adapter comprising:

• a container-side channel section;
• and
• a container-side contact profile with a recess, wherein:
• the container-side channel section is configured to form a continuous channel together with a corresponding vaporizer-side channel section when the adapter is connected to the port section;
• the container-side contact profile is configured to form an area of a surface of the adapter that points towards the port section when the adapter is connected to the port section;
• the adapter is configured such that with the adapter is connected to the port section, the container-side contact profile is in contact with a corresponding projection of the vaporizer-side contact profile without an intermediate space and a corresponding projection of the vaporizer-side contact profile positive lockingly meshes with the recess.
