Abstract

A flow sensor sub-assembly for sensing flow of a fluidic medicament is disclosed. The flow sensor sub-assembly includes a first spring contact and a second spring contact. The spring contacts are secured to a base that has a circuit for conducting an electrical signal to and from the spring contacts to a microprocessor. The first spring contact is in electrical communication with a first piezo element and the second spring contact is in electrical communication with a second piezo element. The first spring contact has a first contact force against the first piezo element and the second spring contact has a second contact force against the second piezo element, and the first and second contact forces are equivalent. A circuit board for interfacing to a flow sensor having a plurality of piezo elements for transmitting a flow signal indicative of flow of fluidic medicament is also disclosed.

Claims9

Dependent claims

A system, comprising:

a computer;
a plurality of flow sensor systems configured to wirelessly communicate with the computer, wherein each flow sensor system includes:
(i) a flow sensor for sensing a flow of a fluidic medicament administered through that flow sensor system, the flow sensor including an injection port configured to be connected to an encoded syringe containing the fluidic medicament, and (ii) a base configured to be removably connected to the flow sensor, the base including a camera configured to read a machine readable indicia provided on a label of the encoded syringe;
wherein the computer is configured to:
receive, from each flow sensor system, information associated with the fluidic medicament;
and
control, based on the information associated with the fluidic medicament received from each flow sensor system, a display to display, for each flow sensor system, a real-time representation of the fluidic medicament administered through that flow sensor system.
