Abstract

The present invention provides a fluid sampling device comprising a port insert, a plurality of flexible conduits, and a plurality of sample containers. The port insert comprises a body having a plurality of shafts therethrough and sample gating means for individually opening and closing any of said shafts to enable the flow of fluid therethrough. The flexible conduits (e.g., flexible tubing) are equal in number to the elongate member, with each flexible conduit connected to or otherwise in fluid communication with an individual shaft. Similarly, the sample containers (e.g., flexible bags) are equal in number to the conduits, with each sample container connected to an individual conduit opposite the connection to the shaft. A specific configuration for the port insert, as well as kit containing sterilized components of the fluid sampling device, are also described.

Claims

1. A fluid sampling device comprising:

(a) a port insert comprising a body having a plurality of shafts therethrough and sample gating means for individually opening and closing any of said plurality of shafts to enable the flow of fluid, said sample gating means comprising a plurality of rigid elongate members positioned within the plurality of shafts, the elongate members having a front and a rear with the front of the elongate members being positioned adjacent a fluid receptacle, the elongate members having a cap and an opening to a passage of the elongate member behind the cap, the elongate members being displaceable between “

open” and

“

closed”

positions such that fluid can flow into the opening behind the cap and through said passage in each member when in said “

open”

position, but not in said “

closed”

position;

(b) a plurality of flexible conduits, equal in number to said plurality of shafts, each flexible conduit in fluid communication with an individual passage of a member; and

(c) a plurality of sample containers, equal in number to said plurality of conduits, each sample container in fluid communication with an individual conduit.

2. The fluid sampling device of claim 1, wherein each of said elongate members are linearly displaceable within one of said shafts between said “

open” and

“

closed”

positions.

3. The fluid sampling device of claim 1, further comprising integral locking means in the form of an anchor to secure said elongate member in either said open position or said closed position or both.

4. The fluid sampling device of claim 1, further comprising integral block to prevent said elongate member from being pushed too far in the open position.

5. A fluid sampling kit for aseptically retrieving a fluid sample from a fluid receptacle, the fluid receptacle provided with a port, the fluid sampling kit comprising sterilized packaging containing

a sterilized fluid sampling device comprising (a) a body and one or more elongate members, said body having one or more shafts therethrough connecting a first open end of the body with a second open end of the body, said body shaped to fit substantially water-tight within said port such that said first open end faces inside said fluid receptacle and said second open end faces outside said fluid receptacle, said one or more elongate members having a front and a back and shaped to fit substantially water-tight within said one or more shafts, said elongate members being fitted within said shaft with the front thereof proximate said first open end and the back thereof proximate said second open end, said one or more elongate members having a cap and an opening to a passage of each of the one or more elongate members behind the cap, said one or more elongate members being movable within said one or more shafts from an open position to a closed position, whereby the release of fluid out of said fluid receptacle through said fluid sampling device is prevented when said one or more elongate members occupies said closed position and allowed when said one or more elongate members occupies said open position;

(b) one or more sterilized flexible tubes connected to said back of each of said one or more elongate members; and

(c) one or more sterilized collection receptacles for collecting fluid released from said fluid receptacle through said fluid sampling device when said one or more elongate members are moved to said open position, the sterilized collection receptacles being connected to said one or more flexible tubes.
