  • Patent number: 5558637
    Abstract: An implant injection device for once-only use includes an elongated implant housing (10), a cannula (11) and a plunger (20) which is longitudinally movable in the implant housing. The surface (21) of the plunger and the inner wall (15) of the implant housing are equipped with interacting projections (22, 12) which permit the plunger to move inwards into the implant housing but which prevent the removal of the plunger from the implant housing.

  • Patent number: 5400804
    Abstract: The invention relates to a method and an equipment for inserting a tubular medicinal capsule on a support. In accordance with the invention, the opening extending through the capsule is expanded by blowing pressurized air into the opening immediately ahead the support being inserted into the opening. After the capsule has entered into its position, the pressurization is relieved, whereby the capsule opening contracts and locks the capsule on the support.

  • Patent number: 5369943
    Abstract: The invention relates to providing a medicinal rod with a shell. The shell is formed from a hose, which is expanded by pressurizing its inner space. The medicinal rod is pushed into the expanded hose, after which the pressure is relieved. The hose tightens over the rod after the pressure relief.

  • Patent number: 5348062
    Abstract: Apparatus for filling a plurality of capsules with a selected medicine, the capsules each having a closed lower end and an open top end and being mounted in the apparatus for filling the medicine into the capsules through the open top end, the apparatus comprising a dosing mechanism which separately measures a selected quantity of the medicine for input into each capsule; a capsule filling mechanism comprising a plurality of funnels each having an axis, the funnels each receiving a measured quantity of medicine and funneling the received medicine to an open delivery end of the funnels; the capsules being mounted such that the open top ends of the capsules are disposed at the open delivery ends of the funnels for receipt of the measured quantities of medicine; the filling mechanism further comprising a plurality of spiral spring mechanisms, the spiral spring mechanisms being insertable through the open top ends and removable from the capsules, the spiral spring mechanisms further being rotatable simultaneously

  • Patent number: 5347794
    Abstract: Apparatus for manufacturing a subcutaneous capsules filled with a selected medicine comprising: a tube cutting mechanism which cuts a continuous length of tubing into a plurality of tubular capsules, each capsule having an open top end and an open bottom end; a capsule support mechanism which holds the capsules in a predetermined array, the bottom open ends of the capsules being sealed by a sealing mechanism; a plurality of spring mechanisms insertable into the open top ends of each capsule held in the array, each spring mechanism receiving a selected quantity of medicine for each capsule, each spring mechanism being rotatable and delivering the selected quantities of medicine into each capsule by insertion of the spring mechanisms into the open top ends of each capsule and rotation of the spring mechanisms.

  • Patent number: 5261211
    Abstract: The invention relates to a method for manufacturing subcutaneous capsules. The capsules are produced by cutting from a silicone tube lengths in excess of the final capsule length. The lenghts are arranged into rows including a defined number of them and in these rows they are filled and sealed. One end of the capsules is first sealed by glue dosaged into their openings. The material for the capsules is dosaged by an aperture disc glidable on a plane surface. By sweeping the upper surface of the disc the dosage volume is limited to the volume defined by the aperture. To regulate the packaging density of the material vibration may be used during the filling of the apertures. The dosaged material is conveyed to the capsule via a feeder funnel, through which a rotatable spiral spring, functioning as a filling screw, is inserted into the capsule to be filled.
