Abstract
The present invention provides a syringe assembly for a medication pump, such as an insulin pump, or the like that includes a pair of protruding structures at one end that mate with the typical pair of opposed recesses or other notch structures of the syringe assembly mating portion of the pump, without the use of a cap structure and needle member, and that may be manufactured primarily from a relatively inexpensive plastic material or the like, while still providing the medication supply back-pressure required to be adequately sensed by the pump electronics, such that the pump accepts the syringe assembly and is “primed” for proper operation.
Claims18
A syringe assembly for use in a medication pump or the like, comprising:
- a housing configured to selectively contain liquid medication or the like;
- a plunger member selectively disposed within the housing configured to selectively expel the liquid medication or the like from the housing through a tube connecting portion of the housing;
- and
- a piston member selectively coupled to the plunger member configured to selectively translate the plunger member within the housing;
- wherein the housing comprises a concentric handle structure and a plurality of angled fin structures configured to mate with a pair of opposed recesses or other notch structures of a syringe assembly mating portion of the medication pump or the like upon rotation;
- and
- wherein the housing comprises a flow restricting collar disposed therein to limit the flow of the liquid medication or the like from the housing, thereby creating a predetermined back-pressure upon translation of the plunger member within the housing.
