Abstract
An arterial syringe assembly is disclosed. The assembly includes a housing with a proximal end that may couple with a syringe barrel and a distal end that may couple with a needle. A needle cover is coupled with the housing at a hinge that may rotate to position the needle cover relative to the needle and may rotate to an orientation aligned with the needle such that the needle is within the needle cover. A needle plug is coupled to the needle cover at a distal end of the needle cover and may include plug material. The needle plug may slide axially relative to the needle to advance the needle plug at a distal end of the needle. A hydrophobic filter is positioned within the syringe barrel to evacuate air through a proximal end of the syringe barrel after the needle tip extends within the plug material.
Claims20
An arterial syringe assembly comprising:
- a housing comprising (i) a proximal end, (ii) a distal end, and (iii) a hinge, the proximal end of the housing is configured to couple with a distal end of a syringe barrel, and the distal end of the housing is configured to couple with a needle;
- a needle cover coupled with the housing at the hinge and being configured to rotate about the hinge to position the needle cover relative to the needle and to rotate to an orientation that is axially aligned with the needle such that the needle is received within the needle cover;
- a needle plug coupled to the needle cover at a distal end of the needle cover and comprising a plug material, the needle plug being configured to slide axially relative to the needle to advance proximally when the needle cover is axially aligned with the needle such that a tip of the needle extends within the plug material;
- and
- a hydrophobic filter positioned within the syringe barrel configured to evacuate air through a proximal end of the syringe barrel after the tip of the needle extends within the plug material.
An arterial syringe assembly comprising:
- a housing comprising (i) a proximal end, (ii) a distal end, and (iii) a hinge, the proximal end of the housing is configured to couple with a distal end of a syringe barrel, and the distal end of the housing is configured to couple with a needle;
- a needle cover coupled with the housing at the hinge and being configured to rotate about the hinge to position the needle cover relative to the needle and to rotate to an orientation that is axially aligned with the needle such that the needle is received within the needle cover;
- a needle plug coupled to the needle cover at a distal end of the needle cover and on an outer surface of the needle cover, the needle plug comprising a plug material, and the needle plug being configured to slide along the outer surface of the needle cover to advance proximally within the needle cover when the needle cover is axially aligned with the needle such that a tip of the needle extends within the plug material;
- and
- a hydrophobic filter positioned within the syringe barrel configured to evacuate air through a proximal end of the syringe barrel after the tip of the needle extends within the plug material.
A method comprising:
- providing an arterial syringe assembly comprising (i) a proximal end configured to couple with a distal end of a syringe barrel, (ii) a distal end coupled to a needle, (iii) a hinge coupled with a needle cover, and (iv) a needle plug, which holds a plug material, coupled with the needle cover at a distal end of the needle cover;
- rotating the needle cover about the hinge to position the needle cover relative to the needle that is axially aligned with the needle such that the needle is received within the needle cover;
- sliding the needle plug axially relative to the needle, when the needle cover is axially aligned with the needle, to advance the needle plug proximally relative to the needle, such that a distal end of the needle extends within and is plugged by the plug material;
- and
- evacuating, via a hydrophobic filter positioned within the syringe barrel, air through a proximal end of the syringe barrel after the distal end of the needle extends within the plug material.
