From Injection Means Moved By Person To Impel Material Into Body Patents (Class 604/124)
  • Patent number: 10426891
    Abstract: A disposable cassette (1) for storing and delivering a medical drug, the cassette (1) comprising a cartridge (7) containing the medical drug, a waste reservoir (8) arranged to receive waste liquid and/or gas, an injection needle (9)arranged to deliver the medical drug, and a valve block (10) being movable between a first position and a second position. The first position establishes a fluid passage between the cartridge (7) and the waste reservoir (8), while preventing fluid flow from the cartridge (7) to the injection needle (9), and the second position establishes a fluid passage between the cartridge (7) and the injection needle (9), while preventing fluid flow from the cartridge (7) to the waste reservoir (8).

  • Patent number: 10398842
    Abstract: An auto-injection syringe shaped similar to a credit card and having a biased injection mechanism operable to drive a needle into a user's body by a fixed distance to dispense a dose of fluid at a subcutaneous location. A safety may be provided to avoid undesired actuation of the injection mechanism. After the safety is bypassed, a trigger may be actuated by the user to allow operation of the injection mechanism. A reciprocating needle-cover resists casual view of the needle by the user during and after use of the syringe. A locking mechanism automatically holds the needle-cover at an extended position to isolate the needle from further contact and to resist re-use of the syringe.

  • Patent number: 7727195
    Abstract: A syringe device includes a syringe tube having a distal end with a passageway in fluid communication with a cavity thereof. A plunger rod slidingly and sealingly engages within the cavity of the syringe tube. The plunger rod includes at least one aperture in fluid communication with a hollow interior of the plunger rod. A plunger tip is engaged with a distal end of the plunger rod and interacts with an inner surface of the side wall of the syringe tube to separate the cavity into first and second areas. The at least one aperture fluidly connects the hollow interior of the plunger rod and the first area of the syringe tube cavity, such that the generally hollow plunger rod interior allows air to move between an outside of the syringe device and the first area of the cavity during sliding movement of the plunger rod within the syringe tube.

  • Patent number: 6102896
    Abstract: The present invention is a single use injector device for injecting parenteral medications which operates by hand force. The injector device has a plunger section and a base. As hand force is applied to a moving portion of the plunger section, break tabs or a snap ring resist its motion toward the patient's skin surface. The break tabs or snap ring release abruptly as the hand force reaches a snap point. The motion of the moving portion then drives the medication through the skin surface and into the body of the patient. If the medication is in liquid form, the actual injection may be carried out through a hollow needle attached to the plunger section. Alternatively, the suddenly increased pressure of the medication at the snap point may be used to form a liquid jet for needleless injection. Part or all of the medication may be contained in a glass needle which dissolves in the body after injection. The injector device requires little training to use, reduces perceived pain, and improves injection safety.

  • Patent number: 4795441
    Abstract: An improved medication administration system includes a series of one way valves disposed closely adjacent and in direct fluid communication with an auxiliary IV line leading to a patient. A plurality of syringes filled with various selected medications are each secured in a tray against axial and lateral movement by depressing them into correspondingly dimensioned longitudinal grooves. The flanges of the syringes abut a lip of the tray to further restrict axial movement. The nozzles of the syringes are connected to the inlets of the valves so that medication can be adminstered intravenously by simply depressing the appropriate syringe plunger. The tray is surrounded by a supporting outer box which includes retractable clamps for fastening the tray to an operating table. A second similarly shaped box is adapted to be clipped to the first box or clamped to the table. The second box can contain miscellaneous medical equipment.
