Abstract: A plastics molding device is disclosed, which provides a plurality of cavities for the simultaneous molding of a plurality of flash caps, and including a punch die, operably supported relative to an outer end of each flash cap cavity, to punch a disc shaped member from a sheet of an appropriate synthetic material, and to position each disc in one of the cavities, in a proper position, to define integral outer end walls in the flash caps, when a suitable molten plastic material is injected into the respective cavities by way of appropriate runner grooves, in a generally conventional manner. Prior to injecting the plastic material, a core pin is advanced into each cavity in a simultaneous relation to the operation of the punch die, to clamp the respective disc members in outer ends of the cavities.

Abstract: A securing device for a catheter placement assembly comprising a pair of oppositely-extending wings connected together by an upstanding portion with an axial through hole along a line of symmetry between the wings and said through hole being adapted to be positioned over a catheter in position so that tape may be applied to the wings to hold the catheter placement assembly in position.

Abstract: A process of molding a teflon tube to a plastic body which includes the steps of jacketing an end zone of a tube of teflon with a sleeve of plastic and with a portion of the teflon extending from the sleeve and heating the extending zone of the teflon so that in response to the heat the teflon curls about the plastic forming a mechanical lock and molding plastic about the plastic sleeve at the end to form a bond and mechanical lock.

Abstract: An improved catheter placement assembly which includes an improved rigid needle and hub assembly and an improved catheter assembly with a flexible cannula jacketing the needle shank and a flexible body of rubbery material on its proximal end with a rigid adapter to connect to an I.V. set; the hub assembly of the needle defines a chamber to protectively house the adapter connection zone during venipuncture.

Abstract: As an article of manufacture an improved drain tube which is flexible and pliable for use after surgical operations and which includes a plurality of ribs arranged in such a fashion about the interior of the column of the tube so that the tube cannot be collapsed and which at all times promotes drainage of body fluids as healing occurs.
