Abstract
A device is provided for receiving a fluid sample. The device includes a fitment having a cavity formed therein. The cavity is provided under vacuum. The fitment also includes a port having a seal. The port is configured to provide fluid connection from an exterior surface of the fitment to the cavity upon opening of the seal. The device optionally includes a collapsible compartment coupled to the fitment and in fluid communication with the cavity.
Claims28
A device for receiving a fluid comprising
- a fitment having a cavity formed therein, the cavity having a reduced pressure, the reduced pressure being below atmospheric pressure relative to an exterior surface of the fitment, and
- a port having a seal, the port configured to provide fluid communication from an exterior surface of the fitment to the cavity upon opening of the seal, and
- a collapsible compartment coupled to the fitment and in fluid communication with the cavity,
- a plunger inserted into the fitment, the plunger comprising a head and neck, wherein the neck is smaller than the head, and
- a separator that is separate from the fitment and seated on top of the fitment, the separator comprising a comb-like structure with teeth and notches.
A device for receiving a fluid comprising
- a fitment comprising a plurality of cavities formed therein, each cavity having a reduced pressure, the reduced pressure being below atmospheric pressure relative to an exterior surface of the fitment,
- a channel fluidly connecting the cavities,
- a port extending from the channel to a surface of the fitment,
- a seal provided at the port, the seal configured to maintain the reduced pressure in the cavities prior to opening the seal,
- a plurality of collapsible compartments affixed to the fitment, each collapsible compartment being in fluid communication with its respective cavity
- a plunger inserted into the fitment, the plunger comprising a head and a neck, wherein the neck is smaller than the head, and
- a separator that is separate from the fitment and seated on top of the fitment, the separator comprising a comb-like structure with teeth and notches.
A device configured to maintain an air-evacuated space therein for drawing a fluid sample into the air-evacuated space, the device comprising
- a fitment including
- a vacuum chamber having a reduced pressure, the reduced pressure being below atmospheric pressure relative to an exterior surface of the fitment prior to opening of a frangible seal,
- a first passageway in communication with the vacuum chamber and configured to communicate with the surrounding atmosphere, and
- a second passageway in communication with the vacuum chamber and configured to communicate with the surrounding atmosphere,
- a frangible seal positioned to block the second passageway to prevent communication between the vacuum chamber and the surrounding atmosphere,
- a flexible compartment coupled to the fitment and formed to define an interior region configured to receive the fluid sample therein, the interior region positioned in fluid communication with the vacuum chamber,
- a plunger received within the vacuum chamber for movement within the vacuum chamber to adjust a volume of open space unoccupied by the plunger within the vacuum chamber
- the plunger comprising a head and a neck, wherein the neck is smaller than the head, and
- a separator that is separate from the fitment and seated on top of the fitment, the separator comprising a comb-like structure with teeth and notches.
