Patent number: 4507111Abstract: A surgical scrub apparatus includes a liquid-containing rupturable cylindrical cartridge which is slidable within a tubular handle having two (2) hollow interior spikes projecting longitudinally from one end. The cartridge can be inserted sufficiently far to cause rupture of the cartridge by both spikes. Liquid from the ruptured cartridge flows through the hollow spikes to an applicator sponge having two (2) wide area applicator surfaces. The hollow spikes are oriented such that one is always disposed higher than the other when the applicator surfaces of the sponge are disposed substantially horizontally. The upper spike can be disposed at a position wherein the liquid pressure applied thereto is less than ambient such that the upper spike serves as a vent passage which admits air into the cartridge. The lower spike thereby serves primarily as an outflow for liquid from the cartridge and air replaces the egressing liquid through the upper spike.Type: GrantFiled: October 19, 1982Date of Patent: March 26, 1985Assignee: Whitman Medical CorporationInventors: Marvin Gordon, Joseph Lichtenstein

Patent number: 4494581Abstract: A forestream sample of a urine void is isolated from a subsequently collected midstream specimen by means of a valve controlled by material which swells to many times its original volume when exposed to urine. The material is disposed in a forestream receiving chamber having a normally open inlet aperture toward which void urine is directed by a funnel, or the like. Upon contact between the liquid and the material in the chamber, the material absorbs the liquid and swells to many times its original volume while forcefully urging a movable member against the aperture to block further entry of liquid into the chamber. Subsequently received liquid is redirected into a midstream specimen collection container. The void stream is initially received by a funnel having a discharge spout which terminates below the level of an overflow opening from which the subsequently received void portion is redirected into the midstream specimen container.Type: GrantFiled: February 18, 1983Date of Patent: January 22, 1985Assignee: Whitman Medical CorporationInventor: Marvin Gordon

Patent number: 4455139Abstract: The surface of the intravenous liquid in a container is maintained at substantially constant height above the patient by suspending the container from an elastic member which stretches along an axis other than the suspension axis for the container. In this manner, the total vertical length of the intravenous unit, including the container, the elastic member and the support hook, is minimized. In a particular embodiment the elastic member is a spring oriented substantially horizontal and combined with a pulley and idler roller to redirect the suspension cord for the intravenous liquid container. In another embodiment the spring is disposed vertically along an axis parallel to the suspension axis. An alarm circuit includes one or more micro switches which are actuated by the moveable spring-attached pulley to provide an audible or visible alarm indication when the suspension spring retracts to a specified position, thereby indicating that the intravenous container is approaching an empty condition.Type: GrantFiled: March 23, 1982Date of Patent: June 19, 1984Assignee: Whitman Medical CorporationInventors: Marvin Gordon, Joseph Lichtenstein, Stephen Kocanowski

Patent number: 4391283Abstract: An incentive spirometer is provided with a mechanism for inhibiting the incentive in response to high flow rate bursts of inhalation so as to promote proper long inhalation efforts by a patient. In one embodiment, the spirometer includes a transparent column located in the inhalation flow path and in which an object is disposed and caused to rise in the column in response to inhalation efforts by the patient. The incentive-inhibiting mechanism may comprise a valve in the rising object which opens in response to excessive flow rate to permit flow through the object and thereby preclude the object from rising. Alternatively, the incentive-inhibiting object may be disposed to admit air into the flow path downstream of the object in response to high flow rate inhalation bursts to thereby reduce the flow rate acting on the object. A variety of embodiments are disclosed.Type: GrantFiled: March 24, 1981Date of Patent: July 5, 1983Assignee: Whitman Medical CorporationInventors: Edward N. Sharpless, Marvin Gordon, Joseph Lichtenstein
