Abstract
A hand-held syringe includes a handle configured for suspending and using the syringe with a single hand. The handle includes pivotally connected first and second members. The members of the handle may be pivotally connected at intermediate positions along the lengths thereof or at or near ends thereof. The first member is associated with, and may be pivotally connected to, a syringe barrel, while the second member is associated with, and may be pivotally connected to, a syringe plunger. The syringe may be configured for a single-use (i.e., it may be disposable). Applications of use and methods of using a hand-held syringe are also disclosed.
Claims20
A single-use syringe, comprising:
- a syringe barrel including a receptacle for receiving fluid;
- a plunger insertable into the receptacle and moveable longitudinally therethrough;
- and
- a handle, including:
- a first member configured to be held by a first part of a user's hand, the first member including an end that terminates in association with the syringe barrel;
- and
- a second member configured to be held by a second part of the user's hand, the second member including an end that terminates in association with the plunger, the first and second members being connected to one another in pivotal relation at intermediate locations thereof.
A hand-held syringe, comprising:
- a syringe including:
- a barrel;
- and
- a plunger disposable within the barrel and moveable along a length of the barrel;
- and
- a handle including:
- a first member associated with the barrel to facilitate movement of the barrel relative to the plunger;
- and
- a second member associated with the plunger to facilitate movement of the plunger relative to the barrel,
- the first and second members of the handle being pivotally connected to one another at ends thereof and configured to facilitate suspension by and use of the syringe with a single hand of a user.
A method for introducing a fluid into a body, comprising:
- coupling one of an injection apparatus and an infusion apparatus to a syringe barrel in communication with a receptacle of the syringe barrel;
- and
- grasping a first handle pivotally associated with the syringe barrel and a second handle pivotally associated with a syringe plunger with a single hand to pivot the first handle and the second handle toward one another to force the syringe plunger into the receptacle of the syringe barrel, the first handle pivoting relative to the syringe barrel, the second handle pivoting relative to the syringe plunger, the syringe plunger displacing fluid within the receptacle to force the fluid through the injection apparatus or the infusion apparatus and into the body.
