Abstract: A cartridge assembly having a cylindrical body, with its forward end being packed down to form an annular flange, a hub fitted on the annular flange, a diaphragm seal positioned on the forward face of the annular flange and held in sealing position by the hub fitted on the annular flange, a piston slidably carried in the rearward portion of the body, a liquid medicament held in the body in the space between the diaphragm and the piston, the hub being made of transparent plastic material and having a first cylindrical portion having an internal diameter sized to fit over the annular flange of the cartridge, a second cylindrical portion extends from the first cylindrical portion and has a diameter less than the first cylindrical portion, a third cylindrical portion extends from the second cylindrical portion and has a diameter less than the second cylindrical portion, a fourth cylindrical portion extends from the third cylindrical portion and has a diameter less than the third cylindrical portion, the fourth cy

Abstract: A combination mixing and discharge capsule for storing separate ingredients which are to be mixed together prior to use and including a container body for one ingredient closed at one end by a slidable piston and the opposite end being displaceably received in a cup-shaped cap which forms a second compartment with a perforated wall of the container body opposite the end containing the piston for receiving a frangible pillow containing a liquid second ingredient to be mixed with the ingredient in the body. The cap has a discharge nozzle extending axially therefrom and when the cap is displaced farther onto the body the innermost wall of the pillow is burst to cause the discharge of the liquid ingredient through the perforated wall end into the container body for mixing with the ingredient therein.

Abstract: A one-piece sealed disposable enema unit with a lubricated rectal tip is disclosed. The rectal tip of the unit is sealed with a break-off tab. Attached to the tab is a sleeve which covers the exterior of the the rectal tip and prevents contamination of the lubricant. Before use, the break-off tab must be twisted off and the tab with the attached sleeve removed. Therefore, the unit is tamper proof and security of the contents is insured.

Abstract: Frangible valve for a closed plastic bag system comprising an upper member having a bore and located within a port on a plastic bag and a solid lower member extending into the bag. The lower member is attached to the upper member by at least one tether and includes a bore-sealing portion attached to the upper member via a weakened portion. In use, the bore-sealing portion is separated from the upper member by external manipulation to permit fluid flow through the bore while the bore-sealing portion remains tethered to the valve. In preferred embodiments, two tethers are included on opposite sides of the bore-sealing portion and the tethered bore-sealing portion includes means for keeping it separated from the bore in a fully open position after the bore seal has been broken.

Abstract: A single use vial is provided in clusters of five or two times five separably joined vials. The vials are molded and filled with a medicated or non-medicated solution and each vial is provided with a converging, planar front wall. The vials include an integral dispensing nozzle, having a conduit which can be exposed by removing a twist off closure. A common separation strip joins the facing side of adjacent vials in the cluster but not the twist off closures. The angle of convergence of the front wall is designed to elevate the conduit above the solution level when the front wall is placed upon a horizontal surface to prevent unwanted dripping prior to use.

Abstract: A medicinal fluid applicator is provided particularly for use with a compressible fluid-filled capsule. The medicinal fluid applicator comprises a frame defining a capsule recess for receiving the capsule. A pressure arm is hingedly attached to the frame for movement toward the capsule to apply pressure thereto. A cutting means depends from the pressure arm to sever the capsule when the arm is moved toward the capsule so fluid will squirt from the capsule upon application of pressure from the pressure arm.

Abstract: Arrangement permitting sterilization during engagement of two coupling components.One coupling component comprises a coupling element (1) and the other a coupling housing (2) capable of connection thereto. The arrangement in accordance with the invention comprises a flexible casing arrangement (6) which surrounds at least one part of the coupling element (1). A disinfectant (9) is contained inside the casing arrangement. The casing arrangement is provided with a seal (6a, 7) to interact with an abutment (8) on the coupling housing (2) during an introductory coupling movement between the components, the casing arrangement (6) being capable of being rolled or pulled along the outside of the coupling element (1) during the progressive engagement between the coupling components until they reach a fully engaged position (FIG. 1).

Abstract: An anesthesia device comprising, a syringe having a chamber, and a device for pumping fluid from the chamber. The device has an elongated cannula attached to the syringe, with the cannula having a lumen in communication with the chamber of the syringe, a plurality of apertures in a distal portion of the cannula communicating with the lumen, and an opening adjacent a distal end of the cannula and distal the apertures, with the opening communicating with the lumen. The device has an element for releasably closing the apertures in the distal portion of the cannula while leaving the opening unobstructed, and for frictionally engaging the cannula to prevent dislodgment during use of the cannula.
