Abstract
A blinding cap for covering a 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.
Claims24
A blinding cap for covering a 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 blinding cap configured to cover a needle shield that receives a needle of a syringe, the blinding cap comprising:
- an elongated body extending between a first end opposite a second end, the body defining a chamber;
- a sleeve projecting from the first end of the elongated body, the sleeve defining a channel;
- and
- a flange positioned in the elongated body, the flange projecting inwardly from the chamber and defining an opening that connects the chamber and the channel, the flange extending entirely around the opening.
A blinding cap comprising:
- a body extending between a first end opposite a second end, the body defining a chamber configured to receive a needle shield, the needle shield configured to receive a needle of a syringe;
- a flange defined by the body, the flange defining an opening, the flange extends continuously around the opening, the opening has a diameter that is less than a diameter of the chamber,
- wherein the flange is configured to restrict withdrawal of the needle shield from the chamber in response to withdrawal of the needle of the syringe from the needle shield.
A blinding cap comprising:
- a body extending between a first end opposite a second end, the body defining a chamber, the chamber including a first chamber portion and a second chamber portion;
- and
- a flange defined by the body, the flange projecting inwardly from the body and defining an opening, the flange continuously extending around the opening, the flange positioned between the first chamber portion and the second chamber portion, the opening having a diameter less than a diameter of the chamber,
- wherein the first chamber portion is configured to receive a needle shield, the needle shield configured to receive a needle of a syringe, and the second chamber portion is configured to receive a portion of the syringe, and
- wherein in response to withdrawal of the needle from the needle shield, the flange is configured to restrict withdrawal of the needle shield from the chamber.
