Miniaturized patch pump system
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.
1. 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.
2. The patch pump system of claim 1 , further comprising a filter positioned between the reservoir and the distal tip of the needle, wherein the filter at least partially filters one or more of phenol and meta-cresol residuals from fluid passing there through.
3. The patch system of claim 1 , wherein the patch system is less than forty-nine millimeters wide by thirty-nine millimeters deep and twelve millimeters thick.
4. The patch system of claim 3 , wherein the patch system is less than about forty-one millimeters wide by about thirty-six millimeters deep and about ten millimeters thick.
5. The patch system of claim 1 , further comprising a valve positioned between the distal tip of the needle and the reservoir, wherein the valve is a one-way valve allowing fluid to flow from the reservoir to the distal end of the needle.
6. The patch system of claim 1 , wherein the reservoir is removable from the electronic assembly and inserter.
7. The patch system of claim 1 , further wherein the electronic assembly selectively transitions the needle between the retracted position to the extended position.
8. The patch system of claim 1 , further comprising:
an inner part configured to selectively transition the needle from the retracted position to the extended position, and
an insertion angle component;
wherein, as the inner part transitions from the retracted position to the extended position, the needle is at least partially deformed by the insertion angle component.
9. The patch system of claim 8 , further wherein the needle is elastically deformed to fit within the inserter in the retracted position and deflects through contact with the insertion angle component as the needle transitions from the retracted position to the extended position.
10. The patch system of claim 9 , further wherein the needle maintains a substantially linear configuration as it extends outside of the base.
11. A patch pump system, comprising:
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.
12. 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 electronic assembly selectively controls an extension length of the needle.
13. The patch system of claim 12 , further wherein the electronic assembly selectively controls an insertion angle of the needle.
