Programmable Device for Precise Medication Delivery

An infusion system comprising:

• a housing defining a medication container interface having a shape and size to receive and secure a first portion of a medication container, the medication container comprising an orifice on a second portion, a pressure chamber being formed when the first portion of the medication container is secured to the medication container interface;
• a pressure source encapsulated within the housing, the pressure source configured to expel gas within the pressure chamber to apply pressure to a surface of the medication container causing fluid within the medication container to be expelled out of the orifice;
• a reference chamber having a known volume;
• a first pressure sensor within the housing configured to measure pressure within the pressure chamber and generate a first pressure value;
• a second pressure sensor within the housing configured to measure pressure within the reference chamber and generate a second pressure value;
• and
• a control unit in communication with the pressure source, the first pressure sensor, and the second pressure sensor, the control unit configured to send signals to the pressure source to control infusion parameters based on the first pressure value and the second pressure value.

An infusion system comprising:

• a housing defining a medication container interface having a shape and size to receive and secure a first portion of a medication container, the medication container comprising a second portion having an orifice and a medication chamber encapsulating fluid disposed between the first and second portions, a pressure chamber being formed when the first portion of the medication container is secured to the medication container interface;
• a pressure source encapsulated within the housing, the pressure source comprising a piezoelectric pump configured to expel gas within the pressure chamber to apply pressure to a surface of the medication container causing fluid within the medication chamber to be expelled out of the orifice;
• a pressure sensor within the housing configured to measure pressure within the pressure chamber;
• a control unit in communication with the pressure source and the pressure sensor, the control unit comprising a programmable controller configured to send signals to the pressure source to control infusion parameters based on the measured pressure, the control unit further configured to determine, based on the measured pressure, one or more of:
• a condition at which all of the fluid in the medication container has been expelled through the orifice, an occlusion condition within an infusion set coupled to the medication container, and removal of the medication container from the medication container interface.
