The delivery through the neck projection corresponds to the volume diminution obtained by the length reduction of the body, for quantitative regulation of the material delivered through the neck. A cup-shaped bushing has its floor engaged on a shoulder projection of the body. The bushing floor has a passage opening for the neck. A piston is slidable in the bushing until it contacts the bushing floor. An indicator arrangement makes a visible indication of the movement path of the piston in the bushing.Type: GrantFiled: June 21, 1996Date of Patent: November 17, 1998Assignee: Bernd HansenInventors: Bernd Hansen, Willy Leu

Patent number: 5337925Abstract: This injection device comprises a housing having a handgrip for operating it. A collapsible fluid container is adapted to fit in the housing under the pressure element of the handgrip. The container has a fill opening with a closure and an injection stem extending out of the housing so that when the handgrip is squeezed, the collapsible fluid container will compress the fluid within it and drive the fluid out through the stem. Conversely, when the fluid container is compressed, the stem can be submerged in fluid and the handgrip spread to enlarge the container and suck fluid into the container.Type: GrantFiled: July 26, 1993Date of Patent: August 16, 1994Assignee: ISPG, Inc.Inventor: Daniel A. Ferrara, Jr.

Patent number: 5328477Abstract: A liquid infusion system includes a flexible, flat, collapsible bag for storing liquid. An outlet communicates with the bag and a valve is used to control liquid outflow through the outlet tube. A rigid housing encloses the bag with the outlet tube projecting therefrom. A spring biased rigid pivot plate is positioned within the housing. The plate exerts pressure on the bag, tending to urge the bag toward a flat collapsed position and to expel liquids through the outlet when any liquid is present in the bag. Spring members are positioned in wells formed in the housing and the plate. The spring members exert a force against the plate.Type: GrantFiled: June 21, 1993Date of Patent: July 12, 1994Inventor: Phillip M. Sitko

Patent number: 4909790Abstract: A liquid infusion device comprises a bladder assembly and a flow-regulating portion. The bladder assembly comprises a tubular outer shaft, an inner shaft slidably received within the outer shaft and a bladder covering the outer and inner shafts. The bladder can inflate in both its radial and axial directions whereby reducing the residual amounts of a liquid drug in the bladder on dispensation of the liquid drug. The flow-regulating portion comprises a pipe having at least one small hole or a pipe having a very small diameter, so that the accurate regulation of the liquid drug can be performed.Type: GrantFiled: June 1, 1988Date of Patent: March 20, 1990Assignee: Nissho CorporationInventors: Hajime Tsujikawa, Toshiki Yoshida

Patent number: 4781689Abstract: A housing having exterior lateral side walls, top and bottom side walls and a single internal wall running adjacent to a lateral side wall. The housing defines an internal rectangular compartment and a parallel side track between the adjacent internal and external walls. A collapsible bag filled with liquid and a slide member, actuable by a constant torque spiral spring are located in the compartment. The slide member has a boss fitting and cooperating with the track to allow the slide member to freely slide without a rotative component under action of the spring.Type: GrantFiled: November 13, 1986Date of Patent: November 1, 1988Inventors: Andrew Sealfon, Carl Yurdin

Patent number: 4692157Abstract: A squeeze-actuated syringe includes a longitudinal body adapted to receive a collapsible ampul. A handle is attached by a hinge to one end of the body, the other end of which is adapted to receive a fitting on the ampul. The handle has a projection or pad on its underside in opposed relationship to the ampul received in the body. When the handle is squeezed toward the body, the ampul is compressed, discharging its contents through a hypodermic needle or the like attached to the fitting. A ratcheting lock mechanism on the handle and the body defines a plurality of selectable detented positions for the handle relative to the body. The handle can be stopped at any selected detented position, thereby allowing the contents of the ampul to be discharged in intermittent stages. In one embodiment, the ratcheting lock mechanism comprises a first serrated member on the body which is co-engageable with a second serrated member on the handle.Type: GrantFiled: December 23, 1985Date of Patent: September 8, 1987Assignee: ErgomedInventors: Boris Landau, Marius Saines
