Abstract
Systems, devices, and methods described herein monitor when the fluid path of a medication in a parenteral medication delivery device is established or interrupted.
Claims20
A system for monitoring a state of a fluid flow path in a medication delivery device, the system comprising:
- an electrical contact sensor comprising a single-piece enclosure comprising at least two electrical contacts, wherein the electrical contact sensor attaches around an outside surface of a portion of the medication delivery device at one end of a connection point within the fluid flow path, wherein the electrical contact sensor is not within the fluid flow path, wherein the electrical contact sensor is operable to communicate a state of an electrical connection, wherein the state of the electrical connection is a presence or absence of electrical current;
- and
- a controller in electrical communication with the electrical contact sensor, the controller comprising an input component operable to receive the state of the electrical connection communicated by the electrical contact sensor and at least one processor operable to assign one or more event times, wherein each event time indicates a time of a change in the state of the fluid flow path,
- wherein connecting the fluid flow path at the connection point causes a change in an electrical connection of the at least two electrical contacts thereby changing the state of the electrical connection.

An electrical contact sensor device for monitoring a state of a fluid flow path in a medication delivery device, the electrical contact sensor device comprising:
- a single-piece enclosure comprising at least two electrical contacts, wherein the electrical contact sensor device attaches around an outside surface of a portion of the medication delivery device at one end of a connection point within the fluid flow path, wherein the electrical contact sensor device is not within the fluid flow path;
- and
- at least one spring operable to bias the at least two electrical contacts from establishing an electrical connection,
- wherein a state of the electrical connection is a presence or absence of electrical current, and wherein connecting the fluid flow path at the connection point causes a change in connection of the at least two electrical contacts thereby changing the state of the electrical connection.
