Abstract
An arterial syringe guide adapted for use with a common arterial syringe is provided for improving the safety of the arterial sampling procedure, for providing easy access to a syringe blood receptacle, and for facilitating the insertion of the needle of a syringe into a targeted artery. An integrated artery stabilizer holds the artery in place during use. A syringe holder retains the needle hub of a hypodermic needle. The blood receptacle component of the employed syringe may be separated from the device, leaving the needle component of the syringe locked on the device for safety.
Claims8
A syringe guide comprising an elongated rigid body that comprises a distal end, a proximal end, and a linear channel disposed along at least part of its length;
- a syringe holder comprising a needle hub holder that comprises a mating surface with a proximal end and a distal end, said mating surface defining a taper from said proximal end to said distal end, whereby said mating surface grips a corresponding mating surface of a needle hub component of a hypodermic needle when said mating surface of said needle hub holder and said mating surface of said needle hub are arranged for surface to surface contact, and a channel link component shaped to slide stably along said linear channel when said needle hub holder is maneuvered up or down said elongated rigid body;
- and
- a blood vessel stabilizer comprising at least one stabilizer finger connected to said distal end of said elongated rigid body whereby said channel positions a needle attached to said needle hub holder in line over a length of a target blood vessel while said stabilizer finger is pressed down lengthwise adjacent to one side of said length of said blood vessel.
A syringe guide comprising an elongated rigid body that comprises a distal end, a proximal end, and a linear channel disposed along at least part of its length;
- a needle hub holder comprising an aperture adapted to grip a portion of a needle hub of a hypodermic needle, said needle hub holder comprising a rigid wall structure and a resilient material retained by said rigid wall structure wherein said resilient material comprises a mating surface that defines the boundaries of said aperture, and said mating surface when engaged with said portion of said needle hub conforms to a contacted surface of said portion of said needle hub while said rigid wall structure remains rigid and retains its original form, said needle hub holder further comprising a channel link component shaped to slide stably and axially along said linear channel;
- and a blood vessel stabilizer comprising at least one stabilizer finger connected to said distal end of said elongated rigid body whereby said channel positions a needle attached to said needle hub holder in line over a length of a target blood vessel while said stabilizer finger is pressed down lengthwise adjacent to one side of said length of said blood vessel.
A syringe guide comprising an elongated rigid body that comprises a distal end, a proximal end, and a linear channel disposed along at least part of its length;
- a hypodermic needle comprising an elongated rigid tube attached to a needle hub, said needle hub comprising a mating surface with a selected shape;
- a needle hub holder comprising a mating surface that corresponds to said shape of said mating surface of said needle hub whereby when mated said mating surface of said needle hub holder firmly grips said mating surface of said needle hub, said needle hub holder further comprising a channel link component shaped to slide stably and axially along said linear channel;
- and
- a blood vessel stabilizer comprising at least one stabilizer finger connected to said distal end of said elongated rigid body whereby said channel positions said needle in line over a length of a target blood vessel while said stabilizer finger is pressed down lengthwise adjacent to one side of said length of said blood vessel.
