Patent ID: 8631716

Claim:
A device for connection to a receptacle of an accessory having an active proximal part that is able to be in put into communication with an inside of the receptacle by an opening of the receptacle, the device comprising: a first element ensuring the rigid attachment of the connecting device to the receptacle, defining a channel between the inside and an outside of the receptacle, serving as a support for the second element and an axial movement guide on an axial course of which two ends of travel correspond to a first distal state and to a second proximal state, helping to serve as a guide for the third element, and helping to delimit the chamber; a second element serving as a support to the third element that is attached rigidly to the second element, and forming a moving, axially sliding element on the course whose two ends of travel correspond to the first distal state and the second proximal state; a third element, to which a base, a body, and a top belongs, serving as a support to the accessory that is attached rigidly to the third element, forming a moving, axially sliding element on the course whose two ends of travel correspond to the first distal state and the second proximal state, ensuring, using the top, the airtight closing of the opening in the first distal state, ensuring, using the top, a protection of the active proximal part in the second proximal state, and helping to delimit the chamber, the top closing the first element in an airtight manner in the first distal state and helping to protect the active proximal part in the second proximal state, the base serving as a support to the accessory that is attached rigidly to the base, ensuring the guiding of the sliding of the third element on and relative to the first element with sealing, and helping to delimit the chamber, the base comprising: at least a first ring in a proximal end part thereof and configured to be able to slide axially, by an outside surface, on and along an inside surface of the tubular wall with sealing, and a second ring at a distal end part thereof configured to be attached rigidly by an outside surface thereof on and against the inside surface of the tubular wall of the second element, inside surfaces of the rings being configured to enable the rigid attachment of the accessory with sealing, and the body comprising a connecting part that is provided with a bore in which the accessory is inserted, and at least one carrying element rigidly connecting the top and the base; and a chamber closed in an airtight manner in the first distal state and in communication with the inside in the second proximal state, the chamber housing the active proximal part inside or placing the active proximal part on a periphery thereof, and one or more of putting a storage liquid therein, and putting a liquid for regulating, monitoring or calibrating the accessory therein or constituting a chamber that is closed in an airtight manner in which the accessory is placed on standby for use.
