The present invention provides fluid sampling device comprising a sampling head having a series of openings through it from one major surface to the other, a plurality of conduits at the downstream side of the openings and a plurality of sample containers. The openings are selectively opened and closed through the use of switches mounted within each opening and the head of the device members, each switch being movable within said head between closed and open positions. The conduits (e.g., flexible tubing) are equal in number to the openings, with each conduit connected to an individual port fitting arranged on a face of the head downstream of the respective opening. 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 port. A specific configuration for the device, as well as a kit containing pre-sterilized components of the fluid sampling device, are also described.

The invention claimed is: 1. A fluid sampling device comprising: a sampling head, the head having a first and a second major face on opposite sides from each other, the head having a plurality of openings extending through it from the first major face to the second major face, each of the openings

The invention claimed is: 1. A fluid sampling device comprising: a sampling head, the head having a first and a second major face on opposite sides from each other, the head having a plurality of openings extending through it from the first major face to the second major face, each of the openings adjacent the second face has an attachment port to which a fluid conduit is attached downstream of the second face and port, each conduit having a collection receptacle in fluid communication with the conduit and being downstream of the conduit, each opening adjacent the first major face having a recess that extends in a plane parallel to the first and second major faces, each recess having a movable switch which selectively covers the opening in a manner allowing movement of said switch between a "closed" and an "open" position in the recess and wherein the device from a side of each switch facing the second major face through the collection receptacle is sterile before each switch is moved from its closed to its open position. 2. The fluid sampling device of claim 1, wherein each recess has a means for providing a water-tight seal with the opening and the recess wherein the means is selected from the group consisting of O-rings and gaskets. 3. The fluid sampling device of claim 1, wherein each recess has a means for providing a water-tight seal with the opening and the recess wherein the means is selected from the group consisting of O-rings and gaskets in each recess. 4. The fluid sampling device of claim 1, wherein each recess has a means for providing a water-tight seal with the opening and the recess wherein the means is selected from the group consisting of O-rings and gaskets on each switch. 5. The fluid sampling device of claim 1 wherein the switch has a hole and a solid portion, the hole having a diameter equal to or less than the diameter of the opening, the hole being in alignment with the opening when the switch is in the open position and the solid portion being in alignment with the opening when the switch, is in the closed position. 6. A fluid sampling kit for retrieving a fluid sample from a fluid receptacle in a sterile manner, the fluid receptacle provided with a port, the fluid sampling kit comprising, enclosed within sterile packaging, a pre-sterilized fluid sampling device comprising a sampling head having a first and a second major face on opposite sides from each other, the head having a plurality of openings extending through it from the first major face to the second major face, each of the openings adjacent the second, face has an attachment port to which a pre-sterilized fluid conduit is attached downstream of the second face and attachment port, each conduit having a pre-sterilized collection receptacle in fluid communication with the conduit and being downstream of the conduit, each opening adjacent the first major face having a recess that extends in a plane parallel to the first and second major faces, each recess having a movable switch which selectively covers the opening in a manner allowing movement of said switch between a "closed" and an "open" position in the recess. 7. The fluid sampling kit of claim 6 wherein the switch has a hole and a solid portion, the hole having a diameter equal to or less than the diameter of the opening, the hole being in alignment with the opening when the switch is in the open position and the solid portion being in alignment with the opening when the switch is in the closed position. 8. The fluid sampling kit of claim 6 further comprising each recess has a water-tight seal with the opening and recess and the water-tight seal is selected from the group consisting of O-rings and gaskets. 9. The fluid sampling kit of claim 6 wherein the switch is moved in a direction selected from the group consisting linear and rotationally in the plane parallel to the first and second major surfaces. 10. A fluid sampling device comprising: a sampling head, the head having a first and a second major face on opposite sides from each other, the body having a plurality of openings extending through it from the first major face to the second major face, each of the openings adjacent the second face has an attachment port to which a fluid conduit is attached downstream of the second face and port, each conduit having a collection receptacle in fluid communication with the conduit and being downstream of the conduit, each opening adjacent the first major face having a recess that extends in a plane parallel to the first and second major faces, each recess having a movable switch which selectively covers the opening in a manner allowing movement of said switch between a "closed" and an "open" position in the recess and wherein the device from a side of each switch facing the second major face through the collection receptacle is sterile before each switch is moved from its closed to its open position and each recess has a water-tight seal with the opening and recess. 11. The fluid sampling device of claim 10 wherein the water-tight seal is selected from the group consisting of O-rings and gaskets. 12. The fluid sampling device of claim 10 wherein the switch is moved in a direction selected from the group consisting linear and rotationally in the plane parallel to the first and second major surfaces. 13. The fluid sampling device of claim 10 wherein the switch has a hole and a solid portion, the hole having a diameter equal to or less than the diameter of the opening, the hole being in alignment with the opening when the switch is in the open position and the solid portion being in alignment with the opening when the switch is in the closed position.
