Filed:

Jul 20, 1993

Appl. No.:

8/094834

Inventors:

Karl Sutherland - Laguna Hills CA
Frederick J. Reinhart - Newport Beach CA
Terry Sprague - Chino Hills CA

Assignee:

Baxter International Inc. - Deerfield IL

International Classification:

A61M 1600

US Classification:

604247

Abstract:

A pressure-responsive control valve is especially useful to control aspiration of fluids from a patient during a surgical procedure. The control valve includes features which control the aspiration suction level communicated to the patient, which prevent reverse flow positive pressure from communicating to the patient, which safely vents such a reverse flow positive pressure in the event it reaches a level jeopardizing the integrity of the valve or plumbing fixtures, and which prevents aspirated fluids from weeping from the valve into the surgical environment in the event that a positive pressure communicates to the inlet of the control valve.

Abstract:

A support assembly for a flat soaker hose comprising a spike insertable into the ground, said spike including mounting provisions at the top end thereof for receiving a clamp assembly at various angular dispositions. The clamp assembly is conformed to provide a plurality of cantilevered fingers disposed in staggered opposing alignment, the interior separation between fingers being dimensioned to provide a clamping fit about the soaker hose. One exterior surface of said clamp is furthermore joined to a mounting structure variously conformed for attachment to the upper end of said spike at various angular alignment. In a first embodiment the upper end of the spike is provided with a planar or rectangular cavity extending vertically downward along or parallel to the axis of the spike and the support structure is conformed as a planar member having a plurality of elongate, coplanar elements extending at various angular alignments therefrom each element being conformed for receipt in said cavity. In various alternative embodiments, the planar support member may include a plurality of radial cutouts each conformed to engage a transverse spine extending across a vertical slot formed on the upper end of the spike, or the spike may be provided with a plurality of angularly aligned cavities extending into the top end thereof with a single element support structure being insertable in a selected one of said cavities. A further engagement structure comprising a ball receivable into a spherically deformed slit which is clamped by way of a wing nut provides the multiple degree of freedom necessary to accommodate hose disposition at various orientations.
