Adhesive thumb ring and syringe assembly, and an adhesive thumb ring for a syringe
View Patent ↗An adhesive thumb ring for a syringe is provided including a ring body and an adhesive surface on the ring body. The adhesive surface is configured to adhere to a plunger head on a syringe barrel of a syringe. For instance, the adhesive thumb ring can be rapidly and securely attached to a curved, T-shaped plunger head of a typically pre-filled, pre-packaged dermal filler syringe. The adhesive thumb ring is particularly suitable for facilitating one-handed pushing and pulling operation of the syringe in the injection of dermal filler into the skin of a patient, significantly assisting the syringe operator in preventing vascular occlusion.
1. An adhesive thumb ring and syringe assembly, comprising:
a syringe, comprising a syringe barrel and a syringe plunger movably attached to the syringe barrel and protruding outward of the syringe barrel through a proximal end thereof, wherein the syringe plunger is selectively movable in a first direction towards an internal space of the syringe barrel and in an opposite, second direction outward of the internal space of the syringe barrel; and
an adhesive thumb ring formed as a separate piece relative to the syringe, the adhesive thumb ring comprising:
a deformable ring-shaped body configured for the insertion therethrough of a person's thumb, the ring-shaped body defined by a concave interior surface and a convex exterior surface,
an adhesive material along the convex exterior surface of the ring-shaped body, the adhesive material defining an outer, convex adhesive surface, and
a peel-off cover covering the convex adhesive surface of the adhesive material; wherein
the syringe and the adhesive thumb ring are configured to adopt:
an initial, first configuration, in which the syringe and the adhesive thumb ring are detached from one another and the peel-off layer covers the convex adhesive surface of the adhesive material of the adhesive ring,
a second configuration, in which the peel-off cover is peeled off of the convex adhesive surface of the adhesive material of the adhesive ring and the ring shaped body is attached to the syringe plunger by an adherence of the convex adhesive surface of the adhesive material of the adhesive thumb ring to an outer surface of the syringe plunger, and
a third configuration, achievable by pressing the ring-shaped body towards the outer surface of the syringe plunger in the second configuration, wherein, in the third configuration, the ring-shaped body and the convex adhesive surface are deformed to provide a greater contact surface area between the convex adhesive surface of the adhesive material and the outer surface of the syringe plunger than in the second configuration.

6. The adhesive thumb ring and syringe assembly of claim 1 , wherein the assembly is configured to adopt:
a pushing configuration in which the syringe and the adhesive thumb ring are in the third configuration and the ring-shaped body and syringe plunger are moving towards the syringe barrel by a force being exerted on the ring-shaped body in the first direction, and
a puffing configuration in which the syringe and the adhesive thumb ring are in the third configuration and the ring-shaped body and syringe plunger are moving away from the syringe barrel by a force being exerted on the ring-shaped body in the second direction.
7. The adhesive thumb ring and syringe assembly of claim 1 , wherein the ring-shaped body is closed and curved.
8. The adhesive thumb ring and syringe assembly of claim 1 , wherein the ring-shaped body is circular.
9. The adhesive thumb ring and syringe assembly of claim 1 , wherein the ring-shaped body is oval or elliptical.
10. The adhesive thumb ring and syringe assembly of claim 1 , wherein the ring-shaped body has a diameter of ¾″ to 1″.
11. An adhesive thumb ring and syringe assembly, comprising:
a syringe, comprising a syringe barrel and a syringe plunger movably attached to the syringe barrel and protruding outward of the syringe barrel through a proximal end thereof, wherein the syringe plunger is selectively movable in a first direction towards an internal space of the syringe barrel and in an opposite, second direction outward of the internal space of the syringe barrel, and further wherein the syringe plunger comprises a curved plunger head at a proximal end thereof, the curved plunger head comprising a concave proximal surface; and
an adhesive thumb ring formed as a separate piece relative to the syringe, the adhesive thumb ring comprising:
a deformable ring-shaped body configured for the insertion therethrough of a person's thumb, the ring-shaped body having a concave interior surface and a convex exterior surface,
an adhesive material along the convex exterior surface of the ring-shaped body, the adhesive material defining an outer, convex adhesive surface, and
a peel-off cover covering the convex adhesive surface of the adhesive material; wherein
the syringe and the adhesive thumb ring are configured to adopt:
an initial, first configuration, in which the syringe and the adhesive thumb ring are detached from one another and the peel-off layer covers the convex adhesive surface of the adhesive material of the adhesive ring,
a second configuration, in which the peel-off cover is peeled off of the convex adhesive surface of the adhesive material of the adhesive ring and the ring-shaped body is attached to the concave proximal surface of the curved plunger head by an adherence of the convex adhesive surface of the adhesive material of the adhesive thumb ring to the concave proximal surface, and
a third configuration, achievable by pressing the ring-shaped body towards the concave proximal surface of the curved plunger head in the second configuration, wherein, in the third configuration, the ring-shaped body and the convex adhesive surface are deformed to provide a greater contact surface area between the convex adhesive surface of the adhesive material and the concave proximal surface of the curved plunger head than in the second configuration.
12. An adhesive thumb ring and syringe assembly, comprising:
a syringe, comprising a syringe barrel and a syringe, plunger movably attached to the syringe barrel and protruding outward of the syringe, barrel through a proximal end thereof, wherein the syringe plunger is selectively movable in a first direction towards an internal space of the syringe barrel and in an opposite, second direction outward of the internal space of the syringe barrel, and further wherein the syringe plunger comprises a curved plunger head at a proximal end thereof, the curved plunger head comprising a concave proximal surface; and
an adhesive thumb ring formed as a separate piece relative to the syringe, the adhesive thumb ring comprising:
