Appl. No.:

09/783444

Inventors:

Nathaniel Leon - Overland Park KS
Phillip L. Gerwig - Perrysville OH

Assignee:

Felton Medical, Inc. - Lenexa KS

International Classification:

A61M 3100

US Classification:

604500, 604 68, 604232, 604187, 604183, 604218, 222326

Abstract:

A disposable unit-dose jet injection syringe having a cylindrically shaped syringe body. The syringe body has a rear open end and a forward closed end. The rear open end has an enlarged diameter forming a flange that retains the syringe to the driving system during the injection cycle. The closed end has an small area coined by a stamping process. A jet orifice is punched through the small area of the closed end. A cavity formed in syringe body is configured to hold a unit dose of liquid, drug, or biological. A piston is slidably engaged within the body to inject the unit dose. A driving system activates the piston to inject the unit dose out of the jet orifice. A method of manufacturing a jet injection syringe is also provided. A method of injecting a medicine is also provided.

Appl. No.:

13/045884

Inventors:

Phillip L. Gerwig - Perrysville OH, US

International Classification:

F41B 11/08

US Classification:

124 57

Abstract:

A rescue launcher system includes a reusable launcher and a one-time-use, pre-packed payload cartridge removably secured to the reusable launcher. The payload cartridge includes a plastic canister, a pressurization system located within the canister and selectively activated by reusable launcher, and a payload located within the canister and which is launched to a remote location upon actuation of the pressurization system. An actuation grip of the launcher selectively actuates the pressurization system, and an interlock is adapted to prevent actuation of the pressurization system unless the interlock and the actuation grip are simultaneously actuated. The payload can be a buoyancy device including a sealed tube and deflated foam within the sealed tube which inflates using internal vacuum after launch of the buoyancy device.

US Classification:

422300

Abstract:

A device for disinfecting and storing endoscopes and the like includes a pair of vertically spaced, wall-mounted brackets between which extend a plurality of parallel connecting rods for supporting the brackets in fixed position relative to each other. A pair of vertically extending tubes for holding disinfecting liquid are locked in position between the brackets by a pair of annular cam-action nuts engaging the top ends of the tubes, the nuts being rotatable to release the tubes for removal and cleaning at a remote location. Elastomeric plugs inserted into the bottom ends of the tubes preclude leakage of disinfecting liquid therefrom. Alternatively, valve assemblies can be provided at the bottom ends of the tubes to permit drainage of the disinfecting liquid from the tubes when in their mounted positions. The uppermost bracket supports the annular nuts which in turn support one or two endoscopes with their insertion portions extending through the annular nuts into the disinfecting liquid within the tubes.

Appl. No.:

8/684943

Inventors:

Phillip L. Gerwig - Perrysville OH

International Classification:

F41B 1106

US Classification:

124 71

Abstract:

A multi-purpose projectile launcher including a body, a barrel forwardly projecting from the body, and a tube forwardly projecting from the body within the barrel and concentric with the barrel to form an annular-shaped space therebetween. A tubular projectile extends over the tube within the barrel and forms a seal between the barrel and the tube. A firing assembly releases gas from a cartridge into an interior chamber, which is in fluid flow communication with the space behind the projectile, to drive the projectile over the tube and out of the barrel. The gas cartridge can be a pressurized gas cartridge having CO. sub. 2 or N. sub. 2 or a self-generating gas cartridge having gunpowder. The projectile can be longitudinally segmented so that a deflector located at a forward end of the tube separates and deflects the segments radially outward from the tube at equal velocities. The segments can be utilized to evenly deploy hobble lines or a net.

Phillip L. Gerwig - Ashland OH

International Classification:

F41C 2700

US Classification:

42 1R

Abstract:

A hypodermic dart gun of the firearm type includes a user-adjustable valve for regulating the feed rate of high pressure combustion gases from an exploded blank cartridge into the breech end of a gun barrel containing a hypodermic dart whereby the velocity of the ejected dart, and hence its effective range, is controlled. A pivotally mounted breech block for receiving the blank cartridge includes a baffle element for generating high combustion gas temperatures and pressures to ensure complete burning of the smokeless type gunpowder used in conventional blank cartridges. The adjustable valve forms a part of the breech block and is comprised of a high-temperature-resistant metering orifice whose cross-sectional area is determined by the position of a threaded member turnable in screwlike fashion into and out of a bore in a wall of the breech block.
