Flow sensor system including spring contacts
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.
1. 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.
2. The system of claim 1 , wherein the real-time representation of the fluidic medicament administered through for each flow sensor system includes a real-time volume of the fluidic medicament administered through each flow sensor system.
3. The system of claim 2 , wherein the real-time representation of the fluidic medicament administered through for each flow sensor system further includes a real-time dose of a medication corresponding to the real-time volume of the fluidic medicament administered through each flow sensor system.
4. The system of claim 1 , wherein the real-time representation of the fluidic medicament administered through for each flow sensor system includes a drug name and a concentration of the fluidic medicament administered through each flow sensor system.
5. The system of claim 1 , wherein the computer is further configured to control the display to display a list of medications previously delivered to a patient associated with the plurality of flow sensor systems.
6. The system of claim 1 , wherein the base of each flow sensor system includes a rechargeable battery.
7. The system of claim 1 , wherein the base of each flow sensor system includes a first window and the camera disposed within or behind the first window, and wherein the first window is aligned with Luer lock threads on the flow sensor when the flow sensor is connected to the base to align the machine readable indicia on the label of the encoded syringe with the camera.
8. The system of claim 1 , wherein the base of each flow sensor system further includes a second window having a light source for providing lighting to the camera disposed within or behind window.
9. The system of claim 1 , wherein the real-time representation of the fluidic medicament administered through each flow sensor system includes an injection bar on the display for each flow sensor system.
