US Patent:

40995275, Jul 11, 1978

Filed:

Mar 16, 1977

Appl. No.:

5/778118

Inventors:

William L. Howell - Washington DC

International Classification:

A61M 516

US Classification:

128214C

Abstract:

A parenteral fluid administration set characterized by a floating siphon operating within a deformable-reformable, plastic-walled, generally cylindrical flow regulator having a normally open-ended overflow tube extending uprightly therein from its bottom end-wall, being thus generally similar both structurally and to a degree functionally to the fluid administration set disclosed in my copending application Ser. No. 608,576 filed Aug. 28, 1975, (now U. S. Pat. No. 3,949,745 dated Apr. 13, 1976) but featuring means whereby the siphon may be primed to initiate fluid flow in controlled amount through the longer leg of the siphon more simply end effectively than by the siphon priming means according to my aforesaid prior-filed application.

Filed:

Feb 6, 1976

Appl. No.:

5/656009

Inventors:

William L. Howell - Washington DC

International Classification:

A61M 516

US Classification:

128214C

Abstract:

A parenteral fluid administration set comprising a container having therein a supply of a fluid to be administered intravenously and being characterized by a floating siphon operative to flow fluid from said container supply thereof at a predetermined rate of flow, said floating siphon comprising a float and at least one siphon U-tube whose shorter leg extends through and is affixed to the float and whose longer leg terminates below the inlet end of said shorter leg and a substantial distance above the container bottom, said longer leg opening to and flowing fluid into an axially non-rigid fluid-flow tube extending through the body of the fluid in said container and delivering same through the container bottom to an I. V. tubing line extending to an infusion needle, said axially non-rigid fluid-flow tube being fashioned from thin plastic or rubber sheet material and being radially collapsible under the pressure of the body of fluid acting thereagainst, but being maintained against complete radial collapse by a pliant coil spring extending through the non-rigid tube and whose coils possess the stiffness requisite to maintaining a fluid-flow passage through said non-rigid tube.

Filed:

Apr 6, 1977

Appl. No.:

5/785218

Inventors:

William L. Howell - Washington DC

International Classification:

A61B 502

US Classification:

128 205G

Abstract:

A sphygmomanometer pressure release means, i. e. a means for releasing the pressure in the pneumatic cuff thereof by simple bending pressure applied to the tubing extending from the "squeeze" bulb to the pneumatic cuff and at a point along the tubing adjacent the squeeze bulb.

National Aeronautics and Space Administration - Washington DC

International Classification:

G01C 2100
G01C 2500

US Classification:

340980

Abstract:

Display for use on propeller driven aircraft comprised of a radially disposed row of lamps 12 embedded in the rear surface of a propeller 11. Measurements of flight data are made by conventional means and converted into digital signals (15 and 18). These digital signals are applied to graphic generators, 16 and 19, which control lamp drivers 13 which in turn control lamps 12 through slip rings 14. The lamps 12 are lit at appropriate times (determined by sync pulses 17) during each revolution of the propeller to cause the flight data in graphic form to appear to the pilot.

Filed:

Dec 19, 1975

Appl. No.:

5/642365

Inventors:

William L. Howell - Washington DC

International Classification:

A61M 514

US Classification:

128214D

Abstract:

A parenteral fluid administration set comprising a plastic bag adapted to be supplied with a predetermined quantity of the parenteral fluid, said bag being foldable over on itself about a transverse fold-over line, a floating siphon enclosed within the plastic bag adapted to follow the level of the parenteral fluid supplied thereto, said floating siphon being adapted to be forced relatively downwardly to substantially its lowermost position in the plastic bag responsive to folding over of the upper portion of said bag on its lower end portion about said fold-over line, thereby immersing the float of the floating siphon in fluid contained in its lower end, as effects conditioning of the floating siphon for operation, the outlet leg of the siphon terminating in a fluid outlet end, said floating siphon being rendered operative to dispense fluid from the plastic bag through said siphon outlet end upon the plastic bag being unfolded and suspended from its upper end.

Inventors:

William L. Howell - Washington DC

International Classification:

A61M 516

US Classification:

128214C

Abstract:

A floating siphon-type regulator for incorporation in parenteral fluid administration sets and which is characterized by a design enabling a simplified, fast start-up procedure and which incorporates a simple, effective means for increasing or decreasing flow rates as called for by the viscosity of the particular solution being administered.
