First Claim
1. An injection system configured to deliver at least one fluid to a subject, the system comprising:
- a fluid delivery module configured to receive a fluid container, wherein once secured to the fluid delivery module, the fluid container is configured to engage an actuator of the fluid delivery module;
at least one motor coupled to the actuator, wherein the at least one motor is configured to selectively move the actuator to create a positive pressure within the fluid container;
wherein the fluid container is configured to be placed in fluid communication with a fluid conduit, a distal end of the fluid conduit being configured to receive a needle for placement within a target injection location of the subject;
a pressure detection assembly in fluid communication with the fluid container, wherein the pressure detection assembly is configured to detect the real-time pressure within the fluid container and the fluid conduit;
wherein the pressure detection assembly comprises a disposable portion and a reusable portion, the disposable portion comprising at least one membrane in fluid communication with fluid being transferred between the fluid container and the fluid conduit to permit for more accurate, real-time fluid pressure detection; and
wherein the reusable portion of the pressure detection assembly comprises a pressure sensor configured to be operatively coupled to the at least one membrane, the pressure sensor being configured to determine the real-time pressure within the fluid container and the fluid conduit; and
a processor configured to regulate at least one aspect of the injection system based on, at least in part, the real-time pressure detected by the pressure detection assembly.
