摘要:
Some embodiments of an infusion pump system include a controller device that is configured to removably attach to a pump device in a manner that provides a secure fitting, an overall compact size, and a reliable electrical connection. In particular embodiments, the controller device can be secured to the pump device in a generally side-by-side arrangement. The compact size can enhance discreteness and portability of the infusion pump system.
摘要:
A drug delivery device having a housing containing a gas generator controlled by an electronic controller. The gas generator generates gas into a reciprocable chamber, whereby reciprocation of the chamber causes a lever to reciprocate a pawl, and this action causes a ratchet to undergo incremental advancement. The device may also be provided with manual control for delivering a bolus dose of drug when necessary.
摘要:
A system architecture for closed loop control of infusion devices is described. The architecture provides means to control the flow from an infusion device as well as in some embodiments the pressure of the delivery. A variety of infusion systems are described that use the closed loop control architecture. In some embodiments the closed loop control may be adapted to current commonly used infusion means such as a gravity feed intravenous system. Other embodiments describe infusion pump system that use biasing or drive mechanisms of springs, elastomers, rotary and linear motors.

摘要:
A dual port syringe has an upper port for connection to a fluid reservoir and a lower port for delivery of the medical fluid under pressure to a patient. A first valve is connected between the fluid reservoir and the upper port, and second valve is connected between the lower port and the patient. During a fill operation, a piston is moved within the syringe to drawn fluid from the reservoir into the syringe through the upper port. During injection operation, the piston moves in an opposite direction to force fluid out of the syringe through the lower port.
摘要:
This invention relates generally to the field of medical devices for delivering contrast media during medical diagnostic and therapeutic imaging procedures and more particularly, this invention relates to improved contrast media delivery systems and methods of use which allow adjustment of contrast media concentration and injection parameters either before or during an injection procedure to provide patient specific dosing of contrast media, thus decreasing the waste and cost of these procedures while increasing their efficiency.

摘要:
An injector for injecting a fluid from a syringe (which syringe includes a body, a plunger moveably positioned within the body, and an encoding device providing syringe information)r includes a housing, a motor disposed within the housing, a controller operably associated with the motor, a sensor operably associated with the controller and operable to read the encoded syringe information provided by the encoding device when the syringe is attached to the injector, a drive member disposed in the housing and powered by the motor, the drive member operable to automatically advance and engage the plunger when the sensor reads the syringe information provided by the encoding device, and a plunger engagement detection device operably associated with the controller and operable to indicate when the drive member of the injector has engaged the plunger of the syringe.
