Abstract
The invention relates to an interfacing device for establishing a connection between a fluid-injection instrument and a flask, said device comprising: fluid flow means configured such as to open into the flask to be perforated when the interfacing device is attached to the flask to be perforated; and a distal opening allowing the flow of gases and a proximal opening allowing the flow of liquids.
Core Innovation
The invention relates to an interfacing device intended to establish a connection between a fluid-injection instrument and a vial to be perforated. A base comprises a first conduit suitable for being attached to the vial to be perforated, a second conduit suitable for allowing circulation of gases in the vial to be perforated, and a third conduit suitable for being connected to the fluid-injection instrument. The device includes means for circulating the fluids having a proximal orifice in fluidic communication with the third conduit, so that communication is established between the fluid-injection instrument and the vial when mounted.
The means for circulating the fluids further comprise a tube housed in the second conduit and translationally movable in the second conduit. The tube comprises a distal end having a distal orifice in fluidic communication with the second conduit, the proximal orifice and the distal orifice being configured for opening into the vial to be perforated when the interfacing device is attached to the vial. A gas exchange device including at least one of a filter or a tank is attached to a proximal end of the tube and is in fluid communication with the tube, thereby allowing circulation of the gases from the vial to be perforated.
The description further refines the structure to improve ergonomic interfacing and contamination reduction, including Y-shaped coaxial or coordinated conduit arrangements and a third conduit angled by an angle α of approximately 30° to 60°. It also describes structural features such as a flared distal tube end, a sealing sleeve to isolate fluids from the gas conduit, and an end piece/perforation-related configuration. A protective member or sachet is used to prevent operator contact while retention fins and other interfacing parts support vial mounting and safe handling, with spatially de-correlated fluid and gas intakes and gravity-assisted ergonomics to reduce contamination risk.
Claims Coverage
The document includes one independent claim (clm-00001) covering an ergonomic vial interfacing device with three conduits, movable tube fluid-circulation means with proximal/distal orifices opening into a vial, and a gas exchange device including at least one of a filter or a tank connected to the tube for gas circulation; dependent claims refine additional structural and geometry constraints.
Three-conduit vial interfacing base with fluid-injection connection
A base comprising a first conduit suitable for being attached to the vial to be perforated, a second conduit suitable for allowing circulation of gases in the vial to be perforated, and a third conduit suitable for being connected to the fluid-injection instrument.
Movable tube in gas-circulation conduit with proximal and distal orifices
Means for circulating the fluids having a proximal orifice in fluidic communication with the third conduit, wherein the means further comprise a tube housed in the second conduit and translationally movable in the second conduit, the tube comprising a distal orifice in fluidic communication with the second conduit, the proximal orifice and the distal orifice being configured for opening into the vial to be perforated when the interfacing device is attached to the vial.
Gas exchange device attached to tube for gas circulation
A gas exchange device including at least one of a filter or a tank attached to a proximal end of the tube, wherein the gas exchange device is in fluid communication with the tube in order to allow circulation of the gases from the vial to be perforated.
Coaxial first and second conduits with angled third conduit
Coaxial first and second conduits, with a third conduit angled between 30° and 60° relative to the second conduit.
Flared distal end of tube
A tube in which the distal end is flared.
End piece with proximal orifice for fluid circulation means
Fluid-circulation means formed by an end piece attached to the distal end of the first conduit, where the end piece has a proximal orifice at its proximal end.
Sealing sleeve to sealingly maintain tube in second conduit
A sleeve located in the second conduit to sealingly maintain the tube within that conduit.
Protective member configured to be attached to the vial
A protective member attached to the first conduit and configured to be attached to the vial to be perforated.
Across the independent claim, the core inventive concept is a three-conduit interfacing device that connects a fluid-injection instrument to a vial to be perforated while using translationally movable tube-based fluid circulation with proximal/distal orifices opening into the vial and a gas exchange device (filter or tank) in fluid communication with the tube to circulate gases from the vial.
Stated Advantages
