摘要： Adjustable volume syringes, and systems and methods for using the same, are disclosed. An adjustable volume syringe may include a delivery syringe, a reservoir syringe located at least in part within the delivery syringe, and a reservoir plunger located at least in part within the reservoir syringe. The delivery syringe is configured to contain a first amount of a fluid. The reservoir syringe is configured to contain a second amount of the fluid. An administration amount of fluid may be determined at or prior to an administration time. An amount of fluid in the delivery syringe may be adjusted to an administration amount at or prior to the administration time based on whether the administration amount is greater than, less than or equal to the first amount. The administration amount of fluid may be dispensed to a patient at the administration time.

摘要： A configurable fluid delivery system and methods for its use are disclosed. The system may include one or more control units, fluid delivery units, fluid actuator units, and disposable units. Data sources and sensors on each of the delivery units, actuator units, and disposable units may provide data to the control unit, thereby identifying the components along with the manner in which they may be configured. The control unit may notify a user regarding the status of any one or more of the delivery, actuator, and disposable units to indicate their appropriateness for delivering a fluid according to one or more selected procedures and protocols. Also disclosed are methods by which the configurable fluid delivery unit may provide data to a user to assist the user in assembling and testing a particular fluid delivery configuration for a specific use.

摘要： Spikes, spike and tubing sets and fluid administrations systems are disclosed. A fluid administration system may include a fluid container having a septum and containing a fluid, a spike, and a flexible tube. The spike may include a hollow access tube extending from a proximal end to a distal end of the spike, a platform surrounding the hollow access tube at a location between the distal and proximal ends, and a sharp tip-end at the distal end. The access tube has a central bore and a sidewall, each extending from the proximal to the distal end. The access tube may include at least one opening extending from the central bore to the sidewall and located between the platform and the sharp tip-end. The flexible tube is configured to connect to the access tube and to deliver fluid from the access tube to a fluid administration location.
