Portable Mechanical Syringe Pump with Universal Syringe Interface

An infusion system comprising:

• hinge means for causing, in response to user-applied force, a top portion to connect with the bottom portion to form a closed position and separate from a bottom portion to form an open position;
• engagement means having a shape and size to receive and secure a syringe;
• pushing means biased towards the engagement means so as to apply force to the syringe;
• and
• linkage means to (i) move transversely in a first direction upon opening of the top portion to cause the pushing means to move away from the engagement means and (ii) move transversely in a second, opposite direction upon closing of the top portion to allow the pushing means to retract towards the engagement means.

A system comprising:

• a syringe having a barrel, flange, and plunger;
• a housing having a top portion, a bottom portion, and an aperture;
• a pair of sliding slots extending transversely along the bottom portion;
• a hinge configured to cause, in response to user-applied force, the top portion to connect with the bottom portion to form a closed position and separate from the bottom portion to form an open position;
• an engagement cavity formed by the housing having a shape and size to receive the flange of the syringe;
• a syringe receiving cavity formed by the housing extending configured to receive the barrel of the syringe;
• a movable pusher positioned within the sliding slots, the movable pusher being biased towards the engagement cavity so as to apply force to the plunger of the syringe when placed in the syringe receiving cavity;
• and
• left and right linkages each having an abutment positioned in a respective one of the sliding slots that are configured to (i) move transversely in a first direction upon opening of the top portion to cause the pusher to move away from the engagement cavity and (ii) move transversely in a second, opposite direction upon closing of the top portion to allow the pusher to retract towards the engagement cavity within the sliding slots independent of the left and right linkages.
