Means For Intermixing Liquid With Solid Or Different Liquid Patents (Class 604/82)
  • Patent number: 10201659
    Abstract: An administration device comprises a container and a mixing device for mixing an active substance (in a first chamber) with a dilution liquid (in a second chamber). The container has a membrane seal at one end and is combined with a mixing device for mixing the active substance. The administration device has an injection needle unit with a distal needle portion facing away from the container for piercing the skin, and disposed opposite thereto is a proximal needle portion facing the membrane when the administration device is in the initial position, which is thrust through the membrane into the container in a mixing position. The administration device includes a protective sleeve arranged coaxially about the injection needle, movable from the initial position only in the proximal direction relative to the container. The protective sleeve can be non-rotatably connected to the container in the mixing position and rotated relative to the mixing device to perform mixing.

  • Patent number: 10143625
    Abstract: A device is disclosed for reconstitution and delivery of an injectable pharmaceutical. A pharmaceutical composition such as a lyophilized drug is provided in a pressurizable fluid reservoir with a pierceable seal. A diluent may be separately provided in a syringe with a needle. When the needle is driven through the seal and the plunger is actuated, fluid from the barrel of the syringe flows into the pressurizable fluid reservoir to simultaneously pressurize the reservoir and mix the diluent with the drug. Pressurized in this manner, the reservoir can then automatically and without further user intervention push the mixture back through the needle and into the barrel of the syringe, further mixing the composition and displacing the plunger to fill the barrel with the reconstituted drug. The needle and syringe can then be detached from the reservoir with the reconstituted drug contained in the barrel and ready for injection.

The released growth factors having a weight of about 70-76 kDaltons are applied in either a filtered or unfiltered state to a wound to promote healing of the wound. The released growth factors are applied topically to the area of a surface wound to effect healing. The released growth factors are also injected into soft tissue, such as a torn tendon, to promote tissue growth and healing. The growth factors are released in one method from a patient's own blood. In another method the growth factors are released from a whole blood source and freeze dried by conventional lyophilization. Then at a later date, the freeze dried product is reconstituted by normal saline for treatment of a patient's wound or for use in a surgical procedure.

  • Patent number: 8961455
    Abstract: A medicament delivery device includes a housing having a proximal housing part and a distal housing part movable relative each other, a drive force mechanism accommodated in the distal housing part, a container filled with medicament arranged within the proximal housing part, a holding member for holding the drive force mechanism in a loaded state, and an actuation member arranged to interact with the holding member for releasing the drive force mechanism from its loaded state. The holding member is arranged to be moved from a disengaged position, in which the holding member is disengaged from the actuation member, to an engaged position, in which the holding member is engaged to the actuation member by moving the housing parts in relation to each other.

    Abstract: A steroid delivery system including a mixing syringe having a first chamber and a second chamber and at least one hypodermic needle is provided. The first chamber of the mixing syringe contains a pre-measured volume of a local anesthetic and the second chamber contains a pre-measured volume of a corticosteroid. An improved mixing syringe and a method for treating pain using the steroid delivery system of the present invention is also provided herein. The improved syringe achieves mixing without the introduction or elimination of air and without puncturing or rupturing of a membrane, diaphragm or other material. The kit concept improves the speed of the procedure, sterility, accuracy of dosing, and immediate availability of disparate items to implement the procedure in a variety of medical practice settings.

  • Publication number: 20150018760
    Abstract: A nasal irrigation system for rinsing nasal and sinus passages or cavities includes a solution preparation unit and a dispensing container. The solution preparation unit includes a first water reservoir, a filter that is in fluid communication with an outlet of the first water reservoir and filters water passing therethrough, a second water reservoir that is in fluid communication with the filter, and a heating element that brings filtered water in the second water reservoir to a boil to clean the filtered water, and a filler port. The dispensing container receives a nasal rinse solution from the solution preparation unit, via the filler port, and administers the nasal rinse solution to a user via a direct nostril interface. The solution preparation unit can also include a cooling element, additive reservoirs for materials to calibrate salinity or to provide a pH buffer, and a control circuit to control operation thereof.

  • Publication number: 20150010528
    Abstract: An anesthetic composition for use e.g. in the administration of a local anesthetic by injection comprises a first component, which comprises hyaluronidase, and a second component which comprises an anesthetic preparation. The composition is both effective and highly shelf stable, and has as an advantage that it may be stored and administered at room temperature. In a particular embodiment, the hyaluronidase is prepared in dry powder form, as by lyophilization. The anesthetic component may be selected from a group of known anesthetics, such as lidocaine, polocaine, xylocaine, novocaine, procaine, prilocaine, bupivacaine, mepivacaine, carbocaine, etidocaine and chincocaine. The composition may be prepared in unit dosage forms, including a single dosage form, for a variety of purposes, and such unit dosage forms may be prepared in a plural chambered syringe or like dispenser, whereby the components are not mixed until administration.
