Plunger disc loading mechanism for syringe pump
First Claim
1. A syringe pump, comprising:
- a housing;
a syringe saddle attached to the housing;
a syringe barrel clamp attached to the housing;
a slidable track connected to the housing;
a plunger holding device attached to the slidable track;
a first movable retainer bar and a second movable retainer bar connected to the plunger holding device, the first movable retainer bar defining a first longitudinal axis and the second movable retainer bar defining a second longitudinal axis, the first longitudinal axis being parallel to the second longitudinal axis; and
an activation mechanism connected to the plunger holding device for moving the first movable retainer bar and the second movable retainer bar away from the plunger holding device and away from each other such that the first longitudinal axis is moved away from the second longitudinal axis while maintaining the first longitudinal axis parallel with the second longitudinal axis,wherein a disc of a plunger can be held by the first movable retainer bar and the second movable retainer bar and between the first and second movable retainer bars and the plunger holding device.

Abstract
A syringe pump is equipped with mechanism for easy handling of syringes of different sizes. The syringe pump is equipped with a plunger holding device. The plunger holding device includes a retainer housing with two retainer bars. The plunger holding device also includes two handles and a sensing plate. When two handles move toward each other, the retainer housing moves forward and two retainer bars moves away from each other. When two handles are released, the retainer housing slides back over a dowel pin attached to the sensing plate and the retainer bars return to their initial position. A plunger'"'"'s disc can be securely held by the retainer bars without introducing error in the sensing of the pushing force of the syringe plunger.
