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.
Claims21
A delivery device system for delivering an infusion medium to a user, the device comprising:
- a disposable housing assembly comprising;
- a base portion defining a reservoir cavity, and comprising a fluid path, the reservoir cavity comprising an outlet port and a septum, the fluid path comprising a fluid channel from the outlet port to a cannula port;
- at least one flexible membrane attached onto the base portion and forming a top of the reservoir cavity and a top of the fluid channel, wherein the fluid path further comprises a series of regions exposed to the flexible membrane, one of the regions being a valve region;
- a tubing connected to the base portion at the cannula port, the tubing in fluid communication with the reservoir cavity;
- and
- a needle insertion device comprising an introduction needle for inserting a cannula into the user's skin, wherein the disposable housing assembly has a passage through which the introduction needle extends.
A delivery device system for delivering an infusion medium to a user, the device comprising:
- a disposable housing assembly comprising:
- a fluidic path having a reservoir, a pumping chamber and an outlet;
- at least one flexible membrane portion forming a portion of the fluidic path and the reservoir, wherein the fluidic path further comprises a series of regions exposed to the flexible membrane portion, one of the regions being a valve region;
- a tubing attached to the outlet, the tubing adapted to connect to a cannula, wherein the reservoir having an interior for containing a fluidic medium, the reservoir having an outlet port and being operatively coupled to a pumping assembly to selectively drive fluid out the outlet port from the reservoir;
- and
- a needle insertion device comprising an introduction needle for inserting the cannula into the user's skin, wherein the disposable housing assembly has a passage through which the introduction needle extends.
A delivery device system for delivering an infusion medium to a user, the device comprising:
- a disposable housing assembly comprising:
- a reservoir having an interior for containing a fluidic medium, the reservoir having an outlet port and being operatively coupled to a pumping assembly to selectively drive fluid out the outlet port from the reservoir interior;
- a substrate having flexible membrane material thereon, and incorporating therein the reservoir and a fluid channel, the reservoir having a septum, the fluid channel being part of a fluid path in the disposable housing assembly from the outlet port to a cannula port and comprising a series of regions exposed to the flexible membrane material, one of the regions being a first valve region and a second a second valve region;
- and
- a tubing portion connected to the cannula port of the disposable housing assembly;
- and a needle insertion device for inserting a cannula into the user's skin, the needle insertion device comprising an introduction needle, wherein the disposable housing assembly has a passage through which the introduction needle extends.
