Various embodiments of the present invention are directed to a device for the reduction of needle insertion site pain in patients. Various embodiments comprise a shell defining a hollow interior cavity filled at least in part by a freezable substance. The shell defines a first surface and a second surface opposite the first surface, and a passage extending through the shell between the first surface and the second surface, wherein the passage is configured to at least partially surround a needle insertion site while a needle is inserted therethrough. At least one of the first and second surfaces comprise a plurality of protrusions distributed therein and configured to be depressed into the skin of the patient. When chilled and depressed against the patient's skin, the freezable device provides a sensory confusion sensation to the patient, thereby reducing perceived pain caused by the needle insertion.
