Abstract
Embodiments included herein are directed towards apparatuses, systems, and methods for fluid dispensing. Embodiments may include piezo-actuated valves, dispense cassettes, and closed loop systems for regulating pressure associated with fluid dispensers. Embodiments of an apparatus may include a piezo-actuated valve and a dispense cassette.
Claims20
A dispensing apparatus comprising:
- a piezo-actuated valve;
- and
- a dispense cassette, wherein the dispense cassette comprises a linear drive motor system configured to operate the syringe.
A dispensing system comprising:
- a piezo-actuated valve comprising a piezo actuator and a drive linkage configured to be actuated by the piezo actuator;
- a dispense cassette comprising a syringe loadable by a twist to connect loader configured to twist into the dispense cassette to load the syringe;
- a linear drive motor system included within the dispense cassette configured to operate the syringe;
- and
- a closed loop system configured to regulate pressure in a fluid channel of the dispensing system by operating the syringe with the linear drive motor system based on a pressure detected in the fluid channel by a pressure sensor of the dispensing system.
2 more elements
A method for regulating pressure in a dispensing system, comprising:
- detecting a pressure in a fluid channel of the dispensing system with a pressure sensor, wherein the pressure is created in part by a dispense cassette having a syringe and a piezo-activated valve system associated with the fluid channel, wherein the dispense cassette comprises a linear drive motor system configured to operate the syringe;
- and
- based on determining that the pressure in the fluid channel is lower than a low pressure threshold, operating the syringe with a linear drive motor system of the dispense cassette to increase the pressure in the fluid channel.
