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.
Claims20
A device for receiving a fluid sample comprising
- a fitment comprising:
- a plurality of cavities formed therein, each cavity having a predetermined reduced pressure relative to an external atmospheric pressure exerted on an exterior surface of the fitment,
- a channel fluidly connecting the cavities,
- a port extending from the channel to the surface of the fitment,
- a seal provided at the port, the seal configured to maintain the reduced pressure within the cavities prior to opening the seal, and
- a plurality of collapsible compartments affixed to the fitment, each collapsible compartment in fluid communication with a cavity.
A pouch assembly for receiving multiple fluid samples therein, the pouch assembly comprising
- a fitment comprising:
- a plurality of cavities formed therein, each cavity defining a volume having a predetermined reduced pressure relative to the atmospheric pressure exerted on an exterior surface of the fitment,
- a first sample entry port, the first sample entry port fluidly connected to a first portion of the plurality of cavities,
- a second sample entry port, the second sample entry port fluidly connected to a second portion of the plurality of cavities,
- a first seal provided at the first port, the first seal configured to maintain the reduced pressure in the first portion of the cavities prior to opening the first seal and configured to dispense fluid from a first fluid sample to each of the first portion of cavities upon opening, and
- a second seal provided at the second port, the second seal configured to maintain the reduced pressure in the second portion of the cavities prior to opening the second seal and configured to dispense fluid from a second fluid sample to each of the second portion of cavities upon opening, and
- a plurality of collapsible compartments affixed to the fitment, each collapsible compartment being in fluid communication with a cavity, and
- a plurality of plungers, each plunger sized to fit within the fitment adjacent one of the cavities such that full insertion of a plunger into the cavity forces fluid from its respective cavity into one of the collapsible compartments.
A device for receiving a fluid sample comprising
- a fitment comprising:
- a plurality of cavities formed within the fitment, each cavity having a wall defining a predetermined volume within each cavity,
- a channel fluidly connecting the cavities,
- a port extending from the channel to the surface of the fitment,
- a seal provided at the port, the seal configured to sealably maintain a gas within the cavities prior to opening the seal,
- a predetermined amount of a gas within each cavity, the predetermined amount being substantially less per unit volume than a gas provided at atmospheric pressure;
- and
- a plurality of collapsible compartments affixed to the fitment, each collapsible compartment being in fluid communication with a cavity.
