Abstract
A system, method, and device for detecting leaks of a, drug at or near an infusion or injection site are disclosed. The system is configured to issue an alert upon detection of a specified chemical signature, such as a combination of gaseous analytes from a leaked therapeutic substance. The system can include a, sensor, such as one or more individual sensors or one or more sensor arrays; a multiplexer; a microcontroller unit; and a communications unit, such as a wireless communications unit.

1-9. (canceled)
A system for detecting a leak of a therapeutic drug at or near an infusion or injection site, the system comprising:
- a sensor configured to detect at least one gaseous chemical emitted from the leaked therapeutic drug and to produce an electrical signal representative of the at least one gaseous chemical;
- a microcontroller unit (MCU) coupled to the sensor, the MCU configured to receive and process the electrical signal;
- and
- a communications unit coupled to the MCU, the communications unit configured to transmit the processed electrical signal to a user device to indicate detection of the leaked therapeutic drug.
A method for detecting a leak of a therapeutic drug at or near an infusion or injection site, the method comprising:
- sensing a signal indicative of at least one gaseous chemical emitted from the leaked therapeutic drug;
- converting the sensed signal into an electrical signal;
- processing the electrical signal to identify, quantify, and/or characterize the at least one gaseous chemical;
- and
- generating an alarm based on the deviation of the at least one gaseous chemical from a threshold range.
A machine readable medium for detecting a leak of a therapeutic drug at or near an infusion or injection site, the machine readable medium storing, encoding, or carrying instructions for execution by a machine, the instructions for:
- sensing a signal indicative of at least one gaseous chemical emitted from the leaked therapeutic drug;
- converting the sensed signal into an electrical signal;
- processing the electrical signal to identify, quantify, and/or characterize the at least one gaseous chemical;
- and
- generating an alarm based on the deviation of the at least one gaseous chemical from a threshold range.
