An injection window guides a caregiver's injection placement to a relatively small area while allowing standard injection procedures to be followed, such as stretching the skin and puncturing the site with a jabbing motion. The injection analgesia system has a needle shield and an analgesia, which are layered together and applied to a skin surface. A needle shield window and a analgesia window align to form the injection window. Advantageously, the needle shield may fold and/or wrap around the injection needle for sharp object protection during and after needle disposal. ## Claims ### Claim 1 A needle shield for shielding a used injection needle, the needle shield comprising: a shield portion having a first side and a second side, the shield portion having a predefined surface area; and a securing portion extending along a periphery of the shield portion on at least one of the first or second sides, wherein the shield portion is configured to wrap around a needle body of the used injection needle, the securing portion configured to couple to the shield portion such that the needle shield adheres to itself as the shield portion wraps around the needle body to securely enclose a portion of the used injection needle including a needle tip. ### Claim 2 (depends on 1) The needle shield of claim 1, wherein the securing potion comprises an adhesive. ### Claim 3 (depends on 1) The needle shield of claim 1, wherein the needle shield wraps spirally around the substantial portion of the used injection needle. ### Claim 4 (depends on 1) The needle shield of claim 1, wherein the needle shield comprises medical-grade plastic. ### Claim 5 (depends on 1) The needle shield of claim 1, wherein the needle shield is flexible. ### Claim 6 A dual-use needle shield for providing analgesia to a patient during an injection procedure and shielding a used injection needle, the needle shield comprising: a shield portion having a first side and a second side, when in use, the first side configured to face away from the patient and the second side configured to face the patient, wherein the second side comprises an analgesia; and a securing portion extending along a periphery of the shield portion, wherein prior to or during the injection procedure, an injection needle is configured to extend through the shield portion from the first side to the second side, the analgesia configured to numb a skin surface enclosed within the second side of the shield portion, and wherein after the injection procedure, the shield portion is configured to wrap around a needle body of the used injection needle, the securing portion configured to couple to the shield portion such that the needle shield adheres to itself as the shield portion wraps around the needle body to securely enclose a portion of the used injection needle including a needle tip. ### Claim 7 (depends on 6) The needle shield of claim 6, wherein the securing potion comprises an adhesive. ### Claim 8 (depends on 6) The needle shield of claim 6, wherein the securing potion comprises interlocking extensions. ### Claim 9 (depends on 6) The needle shield of claim 6, wherein the securing potion comprises an adhesive and interlocking extensions. ### Claim 10 (depends on 6) The needle shield of claim 6, wherein the shield portion is flexible. ### Claim 11 (depends on 6) The needle shield of claim 6, wherein the needle entry window comprises a breakable scored lid. ### Claim 12 A method of providing analgesia to a patient during an injection procedure and shielding a used injection needle using a dual-use needle shield, the method comprising: prior to an injection procedure, advancing an injection needle through the needle shield from a first side to a second side of the needle shield, the second side comprising an analgesia configured to numb a skin surface enclosed within the second side of the needle shield; and after the injection procedure, wrapping the needle shield around a needle body of the used injection needle, wherein the needle shield further comprises a securing portion around a periphery of the needle shield, the securing portion configured to adhere to the needle body and to the needle shield itself as the needle shield is wrapped around the needle body so as to securely enclose a portion of the used injection needle including a needle tip.
