Hanging apparatus for fixing a medical device to a substantially horizontal or substantially vertical support structure

A medical device hanging apparatus for facilitating the removable attachment of a medical instrument alternately to a vertical or a horizontal longitudinal support structure, the hanging apparatus comprising:

• a clamp housing defining a longitudinal enclosure along which are positioned a first plurality of teeth;
• a clamp shaft retractably positioned within the longitudinal enclosure, the clamp shaft being rotatable about a central longitudinal axis and comprising a cylindrical tube fixed with a clamp arm extending from the clamp shaft;
• an internal shaft having a substantially flat surface rotatably positioned within the cylindrical tube of the clamp shaft;
• first and second cam members fixed to the internal shaft and having complementary inclined surfaces;
• and
• a locking member rotatably positioned on the internal shaft between the complementary inclined surfaces of the first and second cam members and including a second plurality of teeth, the locking member being positioned on the substantially flat surface of the internal shaft when the internal shaft is in an unlocked position, the locking member being moved off of the substantially flat surface when the internal shaft is rotated into a locked position such that the second plurality of teeth lockingly engage the first plurality of teeth.

A reduced pressure treatment apparatus comprising:

• a main housing having horizontally and vertically oriented channels on a side thereof;
• a reduced pressure source contained within the main housing to provide a reduced pressure to a tissue site;
• a hanging apparatus comprising:
• a clamp housing fixed within the main housing and defining a longitudinal enclosure along which are positioned a first plurality of teeth;
• a clamp shaft retractably positioned within the longitudinal enclosure, the clamp shaft being rotatable about a central longitudinal axis and comprising a cylindrical tube fixed with a clamp arm extending from the clamp shaft, the clamp arm being selectably positionable between horizontal and vertical positions substantially parallel to the horizontally and vertically oriented channels of the main housing;
• an internal shaft having a substantially flat surface rotatably positioned within the cylindrical tube of the clamp shaft;
• first and second cam members fixed to the internal shaft and having complementary inclined surfaces;
• and
• a locking member rotatably positioned on the internal shaft between the complementary inclined surfaces of the first and second cam members and including a second plurality of teeth, the locking member being positioned on the substantially flat surface of the internal shaft when the internal shaft is in an unlocked position, the locking member being moved off of the substantially flat surface when the internal shaft is rotated into a locked position such that the second plurality of teeth lockingly engage the first plurality of teeth;
