Abstract
A limiter for a dispensing device is provided. The limiter includes a body (20) arranged to mount with at least a portion of a dispensing device (300), and a stop extending from the body. The stop (40) is configured to permit movement a plunger of the dispensing device a predetermined distance in a dispensing direction correlated to a desired volume of medium to be delivered from the dispensing device. The stop is configured to prevent further movement of the plunger in the dispensing direction, thereby limiting the amount of medium delivered from the dispensing device. The dispensing device may be a syringe.
Claims18
A limiter for a syringe, the limiter comprising:
- a single housing forming a receptacle constructed and arranged to mount with at least a portion of a syringe, the housing having a first end and a second end;
- and
- a stop integrally formed with and extending outwardly from the receptacle along a longitudinal axis of a dispensing direction, the stop being configured to permit movement of a plunger of the syringe a predetermined distance in the dispensing direction correlated to a desired volume of medium to be delivered from the syringe, wherein the stop is configured to prevent further movement of the plunger in the dispensing direction through direct contact of the stop with the plunger, thereby limiting an amount of medium delivered from the syringe to the desired volume of medium,
- wherein the limiter is configured to dispense only one desired volume of medium from the syringe.
A method of limiting the dispensing of liquid from a syringe, comprising:
- mounting a syringe with a limiter such that at least a portion of the syringe is mounted with a single housing forming a receptacle of the limiter, the housing having a first end and a second end, wherein a stop integrally formed with the receptacle extends from the receptacle;
- moving a plunger of the syringe a predetermined distance in a dispensing direction correlated to a desired volume of medium to be dispensed, to dispense the medium until the plunger contacts the stop that is configured to prevent further movement of the plunger in the dispensing direction through direct contact of the stop with the plunger, thereby limiting the amount of medium delivered from the syringe,
- wherein the limiter is configured to dispense only one desired volume of medium from the syringe.
