    Abstract: Disclosed is a filter needle in which a filter structure is embedded in the inner space of a fixing member of a syringe needle. The filter structure has an inlet and an outlet, each of which functions as a check valve, and an inlet path and an outlet path provided with a filter, wherein the inlet path and the outlet path are formed at the rear end of the filter structure. Thus, when a medicament liquid flows out from the ampoule and injected into a patient, foreign substances, such as powder generated during the opening of an ampoule, which otherwise might be introduced into the main body of a syringe and injected into a patient, are filtered by a filter. The filter needle enables the medicament liquid to be injected into the patient without exchanging the syringe. The filter needle is integrally formed of medical silicone to enable easy assembly and safety during use.

  • Patent number: 7794449
    Abstract: The present invention provides for the transplantation of tissue from a donor site in a body to a recipient site. The device includes an outer chamber having an interior volume in which a perforated inner chamber can be placed. During the aspiration of tissue, a vacuum is formed in the interior volume of the outer chamber, to draw tissue from a cannula into the perforated inner chamber. The perforations are sized such that fat is collected within the inner chamber, while fluids and other materials are drawn through the perforations, away from the collected fat. For reinjection, the inner chamber can be removed from the outer chamber, and a sleeve positioned to cover the perforations and thereby form a syringe body that can be interconnected to a needle and plunger for reinjection of the collected fat.
