Syringe marking template
A syringe includes an elongated syringe barrel formed of a transparent material; a cannula adjacent one end of the barrel for transmission of fluid into our out of the barrel; a plunger disposed in the barrel and extending through an opposite end of the barrel from the one end; index markings along one side of the barrel for use in identifying various dosage amounts; and a collar moveable along the barrel facilitating indication of a custom marking of a desired dosage amount on the barrel.
1 . A syringe comprising:
an elongated syringe barrel formed of a transparent material;
a cannula adjacent one end of said barrel for transmission of fluid into our out of said barrel;
a plunger disposed in said barrel and extending through an opposite end of said barrel from said one end;
index markings along one side of said barrel for use in identifying various dosage amounts;
a contrast stripe along another side of the barrel opposite said one side, said contrast stripe forming a marking area along said index markings;
a collar moveable along said barrel facilitating indication of or custom marking of a desired dosage amount on said contrast stripe.
2 . The syringe of claim 1 , wherein said collar comprises a transparent or opaque sleeve having opposite edges, either of said edges alignable with one of said index marking corresponding to said desired dosage.
3 . The syringe of claim 2 wherein said sleeve is transparent and formed with a convex projection along an outer surface thereof providing a magnification of underlying ones of said index markings.
4 . The syringe of claim 1 wherein said collar comprises a solid cylindrical sleeve with a linear slot extending about a peripheral portion thereof, said slot sized to permit easier identification or visualization and/or a marking device to penetrate said slot and mark said barrel or contrast stripe to indicate said desired dosage.
5 . The syringe of claim 4 wherein a linear mark is provided on said device, axially aligned with and circumferentially spaced from said slot to thereby enable accurate dosage indication and/or marking of said contrast stripe.
6 . The syringe of claim 1 wherein said collar comprises an O-ring.
7 . The syringe of claim 1 wherein said collar comprises an elongated sleeve, one end of which is adapted to engage a finger press at a proximal end of said syringe barrel, said elongated sleeve having a length such that an opposite end thereof aligns with one of said index markings corresponding to said desired dosage.
8 . The syringe of claim 1 wherein said marking collar is constructed of resilient material and formed with a pair of upper and lower overlapping legs, each terminating in a finger press enabling enlargement of the collar and resilient attachment to said barrel.
9 . A syringe comprising:
an elongated syringe barrel formed of a transparent material;
a cannula adjacent one end of said barrel for transmission of fluid into our out of said barrel;
a plunger disposed in said barrel and extending through an opposite end of said barrel from said one end;
index markings along one side of said barrel for use in identifying various dosage amounts; and
a dosage collar moveable along said barrel facilitating indication of or custom marking of a desired dosage amount on said barrel.
10 . The syringe of claim 9 , wherein said collar comprises a transparent or opaque sleeve having opposite edges, either of said edges alignable with one of said index marking corresponding to said desired dosage.
11 . The syringe of claim 10 wherein said sleeve is transparent and formed with a convex projection along an outer surface thereof providing a magnification of underlying ones of said index markings.
12 . The syringe of claim 9 wherein said marking collar comprises a solid cylindrical sleeve with a linear slot extending about a peripheral portion thereof, said slot sized to permit easier identification of or visualization and/or a marking device to penetrate said slot and mark said desired dosage on said barrel.
13 . The syringe of claim 12 wherein a linear mark is provided on said device, axially aligned with and circumferentially spaced from said slot to thereby enable accurate dosage indication and/or marking of said barrel.
14 . The syringe of claim 12 wherein said collar comprises an O-ring.
15 . The syringe of claim 9 wherein said collar is constructed of resilient material and formed with a pair of upper and lower overlapping legs, each terminating in a finger press enabling enlargement of the collar and resilient attachment to said barrel
