Abstract: A syringe adapter driver system includes a housing configured to receive a syringe device and an actuator attached to the housing, the actuator configured to drive a plunger assembly to cause the plunger assembly to extend or retract through a barrel of the syringe and expel or receive therapeutic. A syringe driver assembly removably attaches the plunger assembly to the housing, wherein the syringe driver assembly moves relative to the housing. A lead screw mechanically couples the actuator to the syringe driver assembly.

Abstract: A ventilator adaptor for converting a ventilator having an inspiratory port and an expiratory port from single patient use to multiple patient use is disclosed. The ventilator adaptor includes an inspiratory splitter, and expiratory splitter and a controller. The inspiratory splitter is attachable to the inspiratory port of the ventilator, and at least two inspiratory branches which are each connectable to a different patient. The expiratory splitter is attachable to the expiratory port of the ventilator, and at least two expiratory branches which are each connectable to the respective different patient. The controller separately controls at least one inspiratory parameter of an inspired fluid in each of the at least two inspiratory branches and/or at least one expiratory parameter of an expired fluid in each of the at least two expiratory branches. A ventilator system having the ventilator adaptor, and methods for ventilating at least two patients are also disclosed.
