Abstract
A blinding cap for covering a rigid needle shield that is covering a needle of a syringe includes an elongated body extending between a proximal end and an opposing distal end, the body at least partially bounding a chamber. An annular sleeve projects from the proximal end of the body and at least partially bounds a channel. A first flange radially inwardly projects from the body into the chamber, the first flange at least partially bounding an opening that provides communication between the chamber and the channel.
Claims23
A blinding cap for covering a rigid needle shield that is covering a needle of a syringe, the blinding cap comprising:
- an elongated body extending between a proximal end and an opposing distal end, the body at least partially bounding a chamber;
- an annular sleeve projecting from the proximal end of the body and at least partially bounding a channel;
- and
- a first flange comprising a continuous annular ring that radially inwardly projects from the body into the chamber, the first flange encircling an opening that provides communication between the chamber and the channel.

A syringe assembly comprising:
- a syringe comprising:
- a syringe barrel having a proximal end and an opposing distal end;
- and
- a needle projecting from the distal end of the syringe barrel;
- a rigid needle shield having a proximal end that terminates at a proximal end face and an opposing distal end, a cavity being recessed into the rigid needle shield through the proximal end, the proximal end of the rigid needle shield being removably coupled to the distal end of the syringe barrel so that the needle is received within the cavity of the rigid needle shield;
- a blinding cap disposed over at least a portion of the rigid needle shield, a portion of the blinding cap being disposed proximally behind the proximal end face of the rigid needle shield so that as the blinding cap is moved distally relative to the syringe barrel, the portion of the blinding cap engages against the proximal end face of the rigid needle shield;
- and
- an annular seal secured to and encircling a portion of the blinding cap and a portion of the syringe barrel, the seal having perforations formed thereon.

A method for using a syringe assembly that includes:
- a syringe comprising:
- a syringe barrel having a proximal end and an opposing distal end;
- and
- a needle projecting from the distal end of the syringe barrel;
- a rigid needle shield having a proximal end that terminates at a proximal end face and an opposing distal end, a cavity being recessed into the rigid needle shield through the proximal end, the proximal end of the rigid needle shield being removably coupled to the distal end of the syringe barrel so that the needle is received within the cavity of the rigid needle shield;
- a blinding cap disposed over at least a portion of the rigid needle shield, a portion of the blinding cap being disposed proximally behind the proximal end face of the rigid needle shield so that as the blinding cap is moved distally relative to the syringe barrel, the portion of the blinding cap engages against the proximal end face of the rigid needle shield;
- and
- an annular seal secured to and encircling a portion of the blinding cap and a portion of the syringe barrel, the method comprising:
- rotating the blinding cap of the syringe assembly relative to the syringe barrel so as to break the seal;
- and
- pulling the blinding cap distally relative to the syringe barrel so that the portion of the blinding cap engages against the proximal end face of the rigid needle shield and separates the rigid needle shield from the syringe barrel.

A syringe assembly comprising:
- a syringe comprising:
- a syringe barrel having a proximal end and an opposing distal end;
- and
- a needle projecting from the distal end of the syringe barrel;
- a rigid needle shield having a proximal end that terminates at a proximal end face and an opposing distal end, a cavity being recessed into the rigid needle shield through the proximal end, the proximal end of the rigid needle shield being removably coupled to the distal end of the syringe barrel so that the needle is received within the cavity of the rigid needle shield, a slot being formed between the rigid needle shield and the distal end of the syringe barrel;
- and
- a blinding cap for covering the rigid needle shield that is covering the needle of the syringe, the blinding cap comprising:
- an elongated body extending between a proximal end and an opposing distal end, the body at least partially bounding a chamber, the rigid needle shield being disposed within the chamber of the elongated body;
- an annular sleeve projecting from the proximal end of the body and at least partially bounding a channel, at least a portion of the syringe barrel being disposed within the channel of the annular sleeve;
- and
- a first flange comprising a continuous annular ring that radially inwardly projects from the body and into the slot between the rigid needle shield and the distal end of the syringe barrel, the first flange encircling an opening that provides communication between the chamber of the elongated body and the channel of the annular sleeve.
