Abstract
A patch pump system that has an electronic assembly, a reservoir for containing a fluid, and an inserter for selectively transitioning a needle from a retracted position to an extended position. The inserter provides a fluid channel that selectively fluidly couples a distal tip of the needle to the reservoir. The needle is at least partially deformed as it transitions from the retracted position to the extended position and the electronic assembly selectively distributes fluid from the reservoir to the distal tip of the needle.
Claims13
A patch pump system, comprising:
- an electronic assembly;
- a reservoir for containing a fluid;
- and
- an inserter for selectively transitioning a needle from a retracted position to an extended position, the inserter providing a fluid channel that selectively fluidly couples a distal tip of the needle to the reservoir;
- wherein, the needle is at least partially deformed as it transitions from the retracted position to the extended position and the electronic assembly selectively distributes fluid from the reservoir to the distal tip of the needle;
- wherein the reservoir has a base surface configured to be coupled to a user, the base surface defining a base plane;
- wherein, the inserter has an inner part that rotates about a rotation axis that is substantially parallel to the base plane to transition the needle from the retracted position to the extended position.

- an electronic assembly;
- a reservoir for containing a fluid;
- an inserter for selectively transitioning a needle from a retracted position to an extended position, the inserter providing a fluid channel that selectively fluidly couples a distal tip of the needle to the reservoir;
- a filter positioned in-line with the fluid channel between the reservoir and the distal tip of the needle and a first one-way valve positioned along the fluid channel between the filter and the reservoir;
- and
- a second one-way valve positioned along the fluid channel between the distal end of the needle and the filter;
- wherein, the needle is at least partially deformed as it transitions from the retracted position to the extended position and the electronic assembly selectively distributes fluid from the reservoir to the distal tip of the needle.
