Abstract
A fluid delivery system and a fluid conduit assembly suitable for use with the system are disclosed herein. The system includes a fluid infusion pump and a fluid conduit assembly coupled to the pump to deliver medication fluid to a user. The fluid conduit assembly includes a structure defining a flow path for the medication fluid, and a gas trapping filter coupled to the structure and positioned in the flow path. The gas trapping filter functions to filter particulates from the medication fluid and retain gas bubbles from the medication fluid.
Claims12
A fluid delivery system comprising:
- a fluid infusion device comprising:
- a housing;
- a fluid reservoir configured to be received by the housing, wherein the fluid infusion device is configured to deliver a medication fluid from the fluid reservoir to a user, and wherein the fluid reservoir defines a first portion of a flow path for the medication fluid during fluid delivery operations;
- a reservoir cap defining a second portion of the flow path for the medication fluid, wherein the reservoir cap comprises:
- a lower body section to receive a portion of the fluid reservoir, the lower body section configured to couple with the housing of the fluid infusion device, and the lower body section configured to seal and secure the fluid reservoir inside a reservoir chamber that resides in the housing,
- a hollow needle in the lower body section, the hollow needle configured to carry fluid from the fluid reservoir into the lower body section, and
- an upper body section defining a conduit in fluid communication with the hollow needle, the upper body section configured to be positioned downstream of the lower body section along the flow path;
- and
- a gas trapping filter positioned in the flow path such that the medication fluid passes through the gas trapping filter during fluid delivery operations, wherein the gas trapping filter is configured to filter particulates from the medication fluid, and
- wherein the gas trapping filter is configured to physically obstruct the flow path such that the medication fluid is not diverted around the gas trapping filter.
