  • Patent number: 9463309
    Abstract: A sealing assembly is utilized for a fluid infusion device that cooperates with a fluid reservoir having a reservoir port and a hollow fluid reservoir needle at least partially located within the reservoir port. The sealing assembly has a reservoir port receptacle with a proximal end, a distal end extending from the proximal end, and a needle opening formed in the distal end to receive the hollow fluid reservoir needle. The sealing assembly also has a fluid chamber located at least partially in the reservoir port receptacle, and a needle sealing element having a self-sealing needle opening formed therein. The needle sealing element is located within the reservoir port receptacle between the distal end and the fluid chamber. The self-sealing needle opening accommodates the hollow fluid reservoir needle when the reservoir port engages the reservoir port receptacle.

  • Patent number: 8679073
    Abstract: A repeater system may control a pump by using a repeater and a user interface. An adhesive patch system may be used for affixing a pump or other object to a human body. Such an adhesive patch system may include two sets of adhesive members, each member including an adhesive material on at least one side so as to attach to the body. The members of the first set are spaced to allow the members of the second set to attach to the body in spaces provided between the members of the first set, and the members of the second set are spaced to allow members of the first set to detach from the body without detaching the members of the second set. Also, fill stations and base stations are provided for personal pump systems.

  • Publication number: 20140074045
    Abstract: The male connector of the present disclosure allows for the flow of fluids therethrough and includes a movable blunt needle having a shoulder projecting radially outwards from the movable blunt needle. The male connector also includes an outer cylinder body formed around the movable blunt needle and disposed in coaxial alignment to the movable blunt needle, a blunt needle retainer which retains the movable blunt needle so that the movable blunt needle can move in an axial direction, and a valve which opens as a result of the movable blunt needle moving in the axial direction when the posterior end presses against the valve. This occurs when the movable blunt needle is inserted into a corresponding connection site, such as a female connector, and the shoulder presses against the connection site to force the movable blunt needle in the axial direction.

  • Publication number: 20140046270
    Abstract: An integrated injection device with pre-packaged medication is disclosed. The integrated injection device includes an ampule that is filled with a fluid medication and a collar with hypodermic needle. The collar includes an axial valve that is positioned between a first end of the collar a second end that includes an exit aperture that is connected to the hypodermic needle. The valve is movable from a first position where the valve blocks fluid communication between the first end and the second end and a second position where valve provides fluid communication between the first end and the exit aperture in the second end. The valve cooperates with a frangible webbing that extends over the second end of the collar and causes the valve to move to the second position when twisted to separate the frangible webbing from the injection device to expose the hypodermic needle.
