RAPID FLUID DELIVERY SYSTEM
A system includes a tubing set and a drive assembly. The tubing set includes inlet tubing couplable to a source of fluid, a valve coupled to the inlet tubing, a syringe coupled to the inlet tubing via the valve, and outlet tubing coupled to the valve. The valve is configured to allow fluid to be drawn from the source of fluid via the inlet tubing into a syringe body of the syringe and to be expelled from the syringe body and through the outlet tubing, and to prevent fluid from being drawn from the outlet tubing into the syringe body and to prevent fluid expelled from the syringe body from flowing through the inlet tubing. The drive assembly is configured to reversibly receive the tubing set such that a drive mechanism is engaged with a plunger of the syringe to reciprocally translate the plunger relative to the syringe body.
1 . A system, comprising:
a tubing set including:
inlet tubing couplable to a source of fluid;
a valve coupled to the inlet tubing;
a syringe coupled to the inlet tubing via the valve, the syringe having a syringe body and a plunger translatable relative to the syringe body to draw fluid into the syringe body and expel fluid from the syringe body, and
outlet tubing coupled to the valve, the valve configured to allow fluid to be drawn from the source of fluid via the inlet tubing into the syringe body and to be expelled from the syringe body and through the outlet tubing, the valve configured to prevent fluid from being drawn from the outlet tubing into the syringe body and to prevent fluid expelled from the syringe body from flowing through the inlet tubing; and
a drive assembly configured to reversibly receive the tubing set such that a drive mechanism is engaged with the plunger of the syringe, the drive mechanism configured to reciprocally translate the plunger relative to the syringe body.
2 . The system of claim 1 , wherein the drive assembly includes a housing having an outer surface, the syringe body and the valve configured to be retained relative to the housing during reciprocal translation of the plunger.
3 . The system of claim 2 , wherein the outer surface defines a first receiving aperture configured to retain a portion of the valve and a second receiving aperture configured to retain a portion of the syringe body, the valve and the syringe body configured to be simultaneously received in the first receiving aperture and the second receiving aperture, respectively, via a lateral displacement of the valve and the syringe body relative to the outer surface, the plunger configured to be engaged with the drive mechanism via the lateral displacement.
4 . The system of claim 2 , further comprising an enclosure configured to be magnetically engaged with the housing such that the syringe body and the valve are retained between the housing and the enclosure.
5 . The system of claim 4 , wherein the enclosure includes a lid rotationally coupled to the housing via a hinge.
6 . The system of claim 1 , wherein the drive assembly includes a motor configured to drive the reciprocal translation of the plunger.
7 . The system of claim 1 , wherein the drive mechanism includes a shuttle configured to engage with the plunger.
8 . The system of claim 1 , wherein the drive assembly includes an actuation lever rotationally coupled to the housing such that rotation of the actuation lever causes translation of the plunger.
9 . The system of claim 8 , wherein the actuation lever defines a cam path and the drive mechanism includes a shuttle configured to engage with the plunger, the shuttle including a pin disposed within the cam path.
10 . The system of claim 8 , wherein the drive assembly includes a spring arranged to apply a force to the actuation lever to urge a trigger of the actuation lever from a retracted position to an extended position, the force being greater when the trigger is in the retracted position than when the trigger is in the extended position.
