摘要： Devices, systems, and methods for minimization of backlash in a syringe pump are described herein. Syringe pumps may comprise a syringe including a cylindrical body and a plunger, and a controller. The plunger may comprise a linear gear that may operably couple with a circular gear in the controller. The controller may be configured to bias the circular gear in a biasing rotational direction, thereby positioning the plunger to move towards a biasing translational direction. The methods may comprise determining a backlash compensation amount, determining a fluid transfer movement amount, moving at least one component of the syringe pump the backlash compensation amount and the fluid transfer movement amount in a first direction, and moving the at least one component of the syringe pump a biasing movement amount in a second direction opposite the first direction to re-engage the first gear and the second gear to minimize backlash.

摘要： An infusion device (1) for administering a medical fluid to a patient (P) comprises a receptacle (12) for receiving a syringe (2), the syringe (2) comprising a tube (20) and a piston (21) movable with respect to the tube (20), a pusher device (11) for exerting a force onto the piston (21) for delivering a medical fluid from the tube (20) towards a patient (P). A sensor device (14) is arranged on the pusher device (11) for measuring a force exerted on the piston (21) by the pusher device (11). A holding element (17) is arranged on the pusher device (11), the holding element (11) being movable with respect to the pusher device (11) between a non-actuated position, in which the holding element is configured to hold the piston (21) on the pusher device (11), and an actuated position for releasing the piston (21) from the pusher device (11). A processing device (15) serves for controlling operation of the infusion device (1). Herein, the processing device (15) is configured to evaluate a sensor signal measured by the sensor device (14) in the actuated position of the holding element (17) and to determine a value indicative of a sensitivity of the sensor device (14) based on said sensor signal measured by the sensor device (14) in the actuated position of the holding element (17) and based on a reference value (S0).

摘要： A trigger condition for entering a syringe empty mode is determined. The trigger condition includes adjusting an operational parameter of an infusion device associated with the syringe to complete a fluid delivery performed by the syringe. The fluid delivery is monitored and, responsive to the fluid delivery satisfying the trigger condition, the infusion device is caused to enter the syringe empty mode. While in the empty mode, a flow rate or threshold associated with the fluid delivery is adjusted to facilitate emptying a fluid from the syringe, and an alert is provided when the threshold associated with the fluid delivery has been satisfied.

Entkopplung des Schlittens (20) an bzw. von der Schubstange (10). Während der Kopplung wird in einem ersten Kopplungszustand ein Schlittenvorschub des Schlittens (20) gemäß dem Längshub der von einer axialen Ausgangsposition bewegbaren Schubstange (10) erzeugt. In dem ersten Entkopplungszustand wird die Schubstange (10) für eine von dem Schlitten (20) getrennte Bewegung freigegeben. Offenbarungsgemäß weist die erste Klemmvorrichtung zumindest einen zu ihrer Aktuierung mit der Steuereinheit (110) verbundenen zweiten Piezo-Aktor auf, wobei der zumindest eine zweite Piezo-Aktor eingerichtet ist, durch dessen Ausdehnen oder Zusammenziehen zumindest den ersten Kopplungszustand zu bewirken.

摘要： A patch pump system (100) that has an electronic assembly (106), a reservoir (102) for containing a fluid, and an inserter (104) for selectively transitioning a needle (206) from a retracted position to an extended position. The inserter provides a fluid channel that selectively fluidly couples a distal tip of the needle to the reservoir. The needle is at least partially deformed as it transitions from the retracted position to the extended position and the electronic assembly selectively distributes fluid from the reservoir to the distal tip of the needle.
