Abstract
An ergonomic syringe includes a slide member, wherein force exerted on the slide member causes movement of a syringe plunger within a hollow or partially hollow syringe barrel, for withdrawing fluid from a source into the syringe, and also includes a reusable adaptor for use with existing conventional syringes, which has a ring that wholly or partially encircles the barrel and indirectly attaches to a plunger flange.
Claims8
An adaptor for a syringe having an at least partially hollow barrel and a plunger, the barrel having a proximal end and a distal end, with an aperture positioned at the proximal end for accepting the plunger, and the plunger being adapted for insertion into the aperture for movement axially within the barrel, comprising:
- at least one ring;
- and
- a plurality of elongate arms positioned axially along the exterior of the barrel, each having a first end attached to the ring and a second end attached to the plunger;
- wherein exerting force axially upon the at least one ring produces axial movement of the adaptor along the barrel, thereby causing the plunger to move a substantially equal distance as the ring along the same axis;
- and wherein at least one of the elongate arms further comprises a slot spatially adapted to accommodate a web of the plunger.
An adaptor for a syringe having an at least partially hollow barrel and a plunger, the barrel having a proximal end and a distal end with an aperture positioned at the proximal end for accepting the plunger and a barrel flange positioned near the proximal end of the barrel;
- and the plunger being adapted for insertion into the aperture for movement axially within the barrel, comprising:
- a first ring and a second ring, one being positioned closer to the distal end of the barrel than the other, wherein at least one of the rings comprises a plurality of members arranged to form a detachable connection;
- and
- a plurality of elongate arms extending axially along the exterior of the barrel;
- at least one extension elbow positioned between the first ring and the second ring for connecting two elongate arms;
- wherein exerting force axially upon the ring positioned closer to the distal end of the barrel produces axial movement of the adaptor along the barrel, thereby causing the plunger to move a substantially equal distance along the same axis.
