Abstract
A syringe assembly includes a syringe barrel having a proximal end and a distal end, a needle hub supporting the needle and coupled to the distal end of the syringe barrel. An adapter is coupled to the hub where the needle extends from the adapter to define a length of the needle for injection as substance into the patient. The adapter has a diameter greater than a diameter of the syringe and has a distal face with a shape and dimension configured for controlling the depth of penetration of the needle into the patient and a proximal face forming a finger grip.
Claims20
A syringe assembly comprising:
- a syringe having a proximal end and a distal end, a needle hub, and a needle extending from a distal end of said needle hub;
- and
- an adapter coupled to said needle hub, said adapter having an axial passage receiving said needle and defining an effective length of said needle, and a distal end surface around said needle for contacting the skin of a patient when said needle penetrates the skin of the patient and limits a depth of penetration of the needle into the skin, said adapter having an annular proximal face comprising a curved convex shape with a dimension forming a finger grip for applying a distal force with respect to the syringe assembly.
A syringe assembly comprising:
- a syringe having a proximal end and a distal end, a needle hub, and a needle extending from a distal end of said needle hub;
- and
- an adapter fixed to said needle hub, said adapter having an axial passage receiving said needle and defining an effective length of said needle, and a distal end surface around said needle for contacting the skin of a patient when said needle penetrates the skin of the patient and limits a depth of penetration of the needle into the skin, said distal end surface of said adapter having a center post around said needle, and an outer annular portion spaced radially outward from said post, and an annular recess between said post and said outer annular portion, said adapter having an annular proximal face comprising a curved convex shape with a dimension forming a finger grip.
