Description

RELATED APPLICATIONS This application claims priority under 35 U.S.C. section 119(e) from U.S. Provisional Patent Application No. 62/945,033, filed December 6, 2019, by P. DiPerna et al., and titled "Rotary Microfluidic Pump", and from U.S. Provisional Patent Application No. 62/944,999, filed December 6, 2019, by K. DiPerna et al., and titled "Medical Device Training Module". BACKGROUND The delivery of therapeutic and non-therapeutic medical fluids is commonly performed intravenously (IV) or subcutaneously using an infusion catheter or cannula and a syringe pump. The mechanism of such syringe type pumps typically compresses a syringe plunger within a corresponding syringe housing in a controlled fashion to provide accurate dosing. For ambulatory pumps this mechanism may be scaled down but generally the small, powerful, and accurate motor that is required for such syringe pumps is expensive. Syringe pumps typically also rely on a motor driven lead screw and attachment to a compressing plunger to not only control the delivery of fluids but also to prevent the unexpected delivery of fluids to a patient over a prolonged period of use by the patient. The accuracy of syringe type pumps as well as other common medical pumps, including peristaltic type pumps, may be compromised by changes in environmental conditions including variation in ambient temperature, changes in ambient pressure as well as other factors. What have been needed are improved pumping mechanisms and methods that are reasonably priced and that can reliably deliver small quantities of medical fluids in an accurate and consistent manner without susceptibility to environmental variations. What have also been needed are devices and methods for assisting patient end users of medical pumps become familiar and confident with the operation of the medical pump systems they are using. SUMMARY The invention is defined by the appended claims. Some embodiments of a medical pump system may include a reservoir cartridge assembly having a fluid reservoir. The fluid reservoir may include a liquid volume, an air volume and a flexible membrane disposed between the liquid volume and air volume which is configured to provide a fluid tight barrier between the liquid volume and air volume. The reservoir cartridge assembly may also include a pump chamber assembly that has a pump chamber with an interior volume which is at least partially bounded by a pump housing. The pump chamber may further include an inlet port in fluid communication with the interior volume and with the liquid volume of the fluid reservoir, and a resilient inlet membrane which is disposed adjacent the inlet port, which is spaced from the inlet port when in a relaxed state, and which is sufficiently distendable towards the inlet port to seal the inlet port in a compressed state. The pump chamber may also include an outlet port in fluid communication with the interior volume and with an outlet conduit. The pump chamber assembly may also include and a resilient outlet membrane which is disposed adjacent the outlet port, which is spaced from the outlet port when in a relaxed state, and which is sufficiently distendable towards the outlet port to seal the outlet port in a compressed state. The pump chamber may also have a displacement chamber disposed within the interior volume and a resilient displacement membrane. The resilient displacement membrane may be disposed adjacent the displacement chamber, form at least a portion of a boundary of the displacement chamber, be sufficiently inwardly distendable from a relaxed state to reduce the volume of the displacement chamber when in a compressed state, and be sufficiently resilient to rebound and increase the volume of the displacement chamber when released from the compressed state. The medical pump system may also include an actuator assembly that is configured to be operatively and releasably coupled to the reservoir cartridge assembly. The actuator assembly may include a cam assembly including an inlet cam lobe which is operatively coupled to the resilient inlet membrane, an outlet cam lobe which is operatively coupled to the resilient outlet membrane, and a displacement cam lobe which is operatively coupled to the displacement membrane. The actuator assembly may also have a motor operatively coupled to the cam assembly and a controller operatively coupled to the motor. Some embodiments of a reservoir cartridge assembly which is configured to be operatively and releasably coupled to an actuator assembly of a medical pump system may include a reservoir base and a fluid reservoir disposed on the reservoir base. The fluid reservoir may include a liquid volume, an air volume and a flexible membrane disposed between the liquid volume and air volume. The flexible membrane may be configured to provide a fluid tight barrier between the air volume and the liquid volume. The reservoir cartridge assembly may further include a pump chamber assembly secured to the r
