Medical tube clearance device
First Claim
Patent Images
1. A medical device for clearing obstructions from a medical tube comprising:
- an enclosure having an interior defining a sterile field and an exterior, the enclosure comprising a distal opening and a proximal opening for providing access to the interior of the enclosure, said enclosure interior comprising a chamber and a discrete conduit in communication with and extending substantially tangentially of said chamber, said conduit extending between and to each of said distal opening and said proximal opening;
a spool provided within the chamber and being rotatable about an axis;
an elongated guide member coupled to the spool such that rotation of the spool accommodates the guide member to wind or unwind about the spool as it is retracted or advanced, respectively, into or out from said enclosure through said distal opening.

Abstract
A device for clearing obstructions from a medical tube includes an enclosure having an interior and an exterior, the enclosure comprising a distal opening for providing access to the interior of the enclosure. The device further includes a spool provided within the enclosure that is rotatable about an axis and an elongated guide member coupled to the spool such that rotation of the spool causes the guide member to wind or unwind about the spool. The device further includes a drive mechanism that is operable to rotate the spool within the enclosure without compromising a sterile field within the enclosure.

25. A medical device for clearing obstructions from a medical tube comprising:
-
an enclosure having an interior defining a sterile field and an exterior, the enclosure comprising an opening for providing access to the interior of the enclosure, said enclosure interior comprising a chamber and a discrete conduit in communication with and extending substantially tangentially of said chamber; a spool provided within the chamber and being rotatable about an axis; and an elongated guide member coupled to the spool such that rotation of the spool in a first direction accommodates the guide member to wind onto the spool as it is retracted, and rotation of the spool in a second direction accommodates the guide member to unwind from the spool as it is advanced, respectively, into or out from said enclosure through said opening; said conduit accommodating the guide member along a path between said spool and a medical tube downstream. - View Dependent Claims (26, 27)
