Disclosed herein is a fluid infusion device of the type that delivers medication fluid to the body of a patient. The device includes or cooperates with a fluid reservoir, and the device has a sealing assembly to receive and form a fluid seal with the fluid reservoir. A retractable sealing element surrounding a hollow fluid delivery needle may be used to seal a port of the fluid reservoir. The port may include a pressure vent that is sealed by the retractable sealing element. In one variation, the reservoir includes a moving valve sleeve that holds a septum. The septum moves to allow the reservoir to vent, and to form a seal with the port when the needle pierces the septum. In another variation, the device includes a needleless sealing assembly. In yet other variations, the device uses a needled fluid reservoir.

Retractable sealing assembly for a fluid reservoir of a fluid infusion device

A method and apparatus for a connection interface between a reservoir or syringe, infusion set tubing, and an infusion pump is provided. The reservoir, a base and a cap are connected to form an integrated unit that is capable of being inserted and secured in an infusion pump housing. The cap and the infusion pump are each provided with at least one sensor or at least one detectable feature, arranged to interact with at least one corresponding detectable feature or sensor on the other of the cap and infusion pump device, to detect one or more of the presence, position or other characteristic of the cap when the cap is aligned or coupled with the infusion pump housing. The detectable feature and sensor may be magnetic, RF, mechanical, optical or any combination.

Smart connection interface

An automated reservoir filling system for a portable medical device is disclosed. The system includes a vial sealed by a septum partially filled with a liquid and a gas occupying a headspace. The system further includes a reservoir with a volume defined between a reservoir septum and a plunger head. The plunger head is coupled to a plunger arm which is further coupled to a drive system. Further included is a transfer system with a vial end that pierces the vial septum and remains in contact with the liquid, and a reservoir end that pierces the reservoir septum and remains in the reservoir volume. A controller coupled to the drive system to actuates the drive system automatically drawing fluid from the vial to the reservoir through the degas system.

Automated reservoir fill system

Various embodiments of the present invention are directed to equalizing pressure in a reservoir containing fluidic media, possibly due to imperfect installation of the reservoir or an external influence such as an altitude or a temperature change. In various embodiments, fluidic media may be expelled from the reservoir through a needle and contained in an interior volume of a pierceable member before the needle pierces the pierceable member to establish a flow path to a user. In other embodiments, fluidic media may be expelled through a port of the reservoir into a chamber or to the outside environment. In further embodiments, fluidic media may be expelled through a channel in a plunger head and out a passage in the reservoir when the channel and passage are aligned. In other embodiments, fluidic media may be expelled through a valve, and the valve may be pierceable by a needle to establish a flow path to the user.

Fluid infusion device and related sealing assembly for a needleless fluid reservoir

A transfer device for filing a fluid reservoir of a fluid infusion device with a fluid is provided. The transfer device comprises a first end to couple to a source of the fluid, and a second end to couple to a pressurizing device. The transfer device also comprises a body interconnecting the first end and the second end, and having an end to couple to the fluid reservoir. The body defining at least one fluid flow path between the source of the fluid, the pressurizing device and the fluid reservoir to enable the filling of the fluid reservoir with the fluid.

Systems for filling a fluid infusion device reservoir

A sealing assembly for a fluid infusion device includes a base plate, a reservoir port receptacle, a flow base component, and a needle sealing element. The receptacle receives the reservoir port, and has proximal and distal ends, and a needle entry in the distal end to receive a hollow needle of a fluid reservoir. The flow base component has an inlet structure defining a fluid chamber, and a needle guide pin protruding therefrom. The end of the guide pin fits within the hollow needle. The needle sealing element has a proximal flange adjacent to the inlet structure, a distal flange opposite the proximal flange, a neck section between the flanges, and a needle opening extending through the neck section. The needle sealing element is positioned within the port receptacle such that the neck section surrounds the end section of the needle guide pin.

An infusion system having a priming detection system to indicate that a component of the system, for example a cannula or needle, is primed with a fluid to be delivered into an individual's body. The infusion system utilizes a reactive element that reacts with the fluid or at least one component of the fluid to be delivered, to produce a color change or a colored complex. The reactive element can be deposited, coated or otherwise incorporated in any component of the infusion system that would benefit from a visible indication of a primed fluid, including, but not limited to a tubing, infusion set, cannula, needle and/or guard element at least partially covering or surrounding a cannula or needle. The visual indication improves the user experience during the priming and filling of the system by providing a clear color change confirmation upon priming completion and prior to insertion into the body.

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.
