Combination reference level indicator, manometer, intravenous fluid supply means and means permitting rapid adjustment of reference levels in accordance with shift in patient elevation

Claim 1

Apparatus associated with supplying fluid intravenously to a patient including apparatus for rapidly adjusting a reference level indicator according to shifts in a patient reference level above floor, whereby a manometer gauge reference level may be rapidly adjusted accordingly, said apparatus comprising a first flexible transparent tube having an indicating fluid therein, first and second vertically disposed adhesive strips, said first strip being attached to said first flexible tube at one end and adapted to be attached to the patient at a predetermined reference level thereon to establish a first reference level above the floor, vertically extending support means, said second adhesive strip being secured to said support means and having a plaque means adjustable positioned thereon, said plaque means having the other end of said first tube attached thereto so as to dispose the indicating fluid level in said first tube at said first reference level, a monometer gauge, and a third vertically disposed adhesive strip removably mounted on said support means, said third strip having adjustably mounted thereon said manometer gauge whereby said gauge fluid may be positioned at said first reference level, a source of intravenous fluid supply at a fixed higher predetermined reference elevation above the floor secured to said support means, a three-way cock connected below said monometer gauge fluid, a second flexible tube from said source to said cock, and a third flexible tube leading from said cock and adapted to be connected into A patient''s vein whereby in one position, said cock establishes communication of supply fluid from said source upwardly against said gauge fluid, in another position said cock establishes communication of supply fluid between the vein and gauge fluid and in a third position said cock continuing supply fluid from said source on therethrough to said vein.
