Abstract
Official abstract text for this publication.
A combined detectional and positional sensor for a syringe pump. The sensor can comprise a syringe thumbpress clamp that is pivotable so that an engagement pin deflects a linear membrane potentiometer first circuit thus providing a closed switch for detection of a syringe in the pump and a variable signal return for indication of plunger head position. Embodiments of the sensor can be used in relatively large syringe pumps and in relatively small syringe pumps, for example.
First claim
Opening claim text (preview).
1 . A syringe pump detectional and positional sensor comprising: a syringe thumbpress clamp; and a linear membrane potentiometer coupled to the syringe thumbpress clamp. 2 . The syringe pump detectional and positional sensor of claim 1 , wherein the syringe thumbpress clamp comprises a bottom portion and an arm projecting from the bottom portion, a projection on a distal end of the arm, a pivot ring fixedly attached to the bottom portion, a pressure arm fixedly attached to the pivot ring, and an engagement pin at a distal end of the pressure arm. 3 . The syringe pump detectional and positional sensor of claim 1 , wherein the linear membrane potentiometer has a first circuit and a second circuit, wherein the first circuit is deflectable. 4 . A syringe pump detectional and positional sensor comprising: a syringe thumbpress clamp comprising a bottom portion and an arm projecting from the bottom portion, a projection on a distal end of the arm, a pivot ring fixedly attached to the bottom portion, a pressure arm fixedly attached to the pivot ring, and an engagement pin at a distal end of the pressure arm; and a linear membrane potentiometer comprising a first circuit and a second circuit, wherein the first circuit is deflectable. 5 . A syringe pump detectional and positional sensor comprising: a holder having an engagement pin; a switch in contact with the engagement pin; and a variable signal indicator in movable contact with the engagement pin.
