Abstract:
1. A device for collecting biological sample from an interior of a catheter, comprising a catheter hub, wherein said catheter hub is hollow and has therein a catheter hub proximal opening and a catheter hub distal opening, wherein said catheter hub distal opening is configured to engage a catheter opening, wherein said catheter hub proximal opening has therein a catheter hub proximal opening interior and a catheter hub proximal opening exterior, wherein said catheter hub distal opening has therein a catheter hub distal opening interior and a catheter hub distal opening exterior; a sheath, wherein said sheath is tubular in shape and has therein an open sheath distal end, a sheath proximal end compartment, and a closed sheath proximal end, wherein said open sheath distal end is securely positioned along the exterior of said catheter hub proximal opening, wherein said sheath proximal end compartment comprises said closed sheath proximal end and a sheath proximal end compartment distal end, wherein said sheath proximal end compartment distal end is partially sealed with said sheath thereby creating a segregated region within said sheath; and a brush, wherein said brush comprises a sample collection section, an extended body, a bristle section, and a brush handle, wherein said brush is positioned within said sheath such that said handle is positioned within said sheath proximal end compartment and said bristle section is positioned near said open sheath distal end such that said sample collection section may be advanced or withdrawn through said catheter hub, wherein as said brush is advanced or withdrawn through said catheter hub said partially sealed sheath proximal end compartment distal end prevents said brush handle from exiting said sheath proximal end compartment.
