US Patent:

42443652, Jan 13, 1981

Filed:

Mar 26, 1979

Appl. No.:

6/023927

Inventors:

Lee E. McGill - Orinda CA
Susan J. Watkins - Berkeley CA

Assignee:

Cutter Laboratories, Inc. - Berkeley CA

International Classification:

A61M 500

US Classification:

128214E

Abstract:

An overpressure device is disclosed for use in a liquid infusion set for the purpose of detecting excessive pressures which may occur during infusion. The device comprises a tubular member with an inlet and an outlet, a closed pressure chamber and a bridging portion containing a small bore passage which connects the pressure chamber with the tubular member. In a preferred form, the interconnecting passage takes a tortuous path. An optical sensor positioned on the pressure chamber will detect the presence of liquid at a predetermined position in the chamber, when the liquid rises as a result of excessive pressure in the set, and respond by stopping the flow of liquid in the set.

Appl. No.:

5/678282

Inventors:

Lee E. McGill - Albany CA
Raymond D. Von Alven - San Raphael CA

Assignee:

Cutter Laboratories, Inc. - Berkeley CA

International Classification:

A63B 2300
A61B 508

US Classification:

272 99

Abstract:

The device is a disposable compact unit comprising a transparent column with an aperture at its base, an air float within the column and with the column mounted on a closed container. A conduit joins the top of the column to an opening into the container. The container is also equipped with a breathing tube and a variable aperture means for varying the size of another opening into the container. By inhaling through the breathing tube, a patient can judge his capacity for alveolar expansion by the height to which the air float rises. Adjustment to any patient's capacity can be easily made by changing the opening in the variable aperture means.

Appl. No.:

6/286117

Inventors:

Raymond D. von Alven - San Rafael CA
Lee E. McGill - Orinda CA

Assignee:

Cutter Laboratories, Inc. - Berkeley CA

International Classification:

B65D 4132

US Classification:

215253

Abstract:

A closure for containers which is inexpensively and easily manufactured and is readily removeable in whole or in part to gain access to contents in the container. The closure comprises a generally flat cap member sealed at its periphery to the mouth of the container. An upstanding tubular member on the surface of the cap is partially surrounded by a score line in the cap and the score line preferably continues all around the cap near its periphery. The tubular member preferably has rigidifying means in its closed top and side walls which can be readily flexed inwardly so that the tubular member can be firmly grasped and pulled to readily initiate a rupture in the score line at a stress-concentrating focal point on that portion of the score line adjacent the tubular member. The cap can then be easily removed by continued pulling of the tubular member.

Assignee:

Cutter Laboratories, Inc. - Berkeley CA

International Classification:

A63B 2300

US Classification:

272 99

Abstract:

The device comprises a closed container with a breathing tube and a means for variably adjusting the size of an aperture into the container. A transparent inclined tube is mounted on the container and houses a moveable air flow indicating member. The tube has a passage at the top leading into the container and a vent at the bottom of the tube allows air to enter to move the flow indicating member up the inclined tube. Air drawn from the container by inspiring through the breathing tube is replaced in part by air entering through the variable aperture means and by the air entering through the vent. By adjusting the size of the variable aperture, one can determine inspiratory capacity as correlated with the amount of air necessary to move the flow indicating member to the top of the tube or to an intermediate position in the tube.

Appl. No.:

6/592993

Inventors:

Lee E. McGill - Orinda CA

Assignee:

Miles Laboratories, Inc. - Elkhart IN

International Classification:

A44B 2100
F16K 706

US Classification:

24543

Abstract:

Device for holding and positioning plastic tubing of an intravenous fluid administration set. Device comprises a generally flat, foldable, elongate structure having two outwardly extending arms connected via an intermediate flexible portion having on opposite sides thereof substantially parallel longitudinal recesses which, when the arms are folded against one another, form a longitudinal channel, generally circular in cross section and capable of holding plastic tubing via friction fit. In preferred embodiments, device includes means for irreversibly locking the arms together in a spring-like manner and a tamper prevention and indication means.
