  • Patent number: 8529532
    Abstract: Described generally herein are tissue therapy devices, which may comprise a sealant layer and a suction apparatus. The sealant layer functions so as to create a sealed enclosure between it and the surface of a patient by forming, preferably, an airtight seal around an area of tissue that requires negative pressure therapy. The tissue therapy device may comprise a suction apparatus. The suction apparatus is typically in fluid communication with the sealant layer and functions so as to reduce the amount of pressure present underneath the sealant layer. The reduced pressure is self-created by the suction apparatus. Together the sealant layer and the suction apparatus preferably create a closed reduced pressure therapy system. Preferably, the pressure under the sealant layer is reduced by expanding the volume of the enclosure space and thereby decreasing the density of the air molecules under the sealant layer.

  • Publication number: 20030040715
    Abstract: A hypodermic injection system particularly for use in mass immunizations having a handpiece with a grasping mechanism for holding ampules filled with injectate, a plunger for driving into the ampule to discharge the injectate in an injection process, an injection spring mechanism for driving the plunger, a motor and/or manual mechanism for cocking the injection spring mechanism, and an ampule ejection mechanism for ejecting ampules after use under control of a release mechanism. Ampules can be loaded, used and ejected without contact by the user of the system or the patient being injected. Also disclosed are a filling station for filling ampules through their injection orifices, and an arming device for setting the injection spring. Ampules are disclosed having a piston which is drivable towards an orifice to discharge injectate through the orifice. Ampules are also disclosed having enlarged proximal portions for easy grasping by the grasping mechanism of the injector.

  • Patent number: 6364860
    Abstract: A resettable display of a device for metered administration of a fluid drug, comprising a housing, a fluid container containing the fluid and provided in or on said housing, an actuating device shiftably mounted by a length in or on said housing, which, upon actuation, shifts a piston in the fluid container in order to displace from the fluid container a fluid dose adjusted by the actuating device, a display provided in or on said housing displaying a measure for the adjusted fluid dose, and a resetting means shifted with the actuating device and thus resetting the display. The display comprises a minimum of one counter ring rotated from a zero position when adjusting the fluid dose by means of the actuating device in relation to the housing. The resetting means mechanically transfers the shift movement of the actuating device into a reverse rotary movement of the counter ring towards its zero position (FIG. 1).

  • Patent number: 5836922
    Abstract: A container for delivery of flowable material has a plastic, deformable container body which can be compressed in its longitudinal direction and a neck of smaller diameter attached to one body end with formation of a projection. 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.

  • Patent number: 5337925
    Abstract: 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.

  • Patent number: 5328477
    Abstract: 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.

  • Patent number: 4692157
    Abstract: 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.
