Abstract
A device is disclosed which couples the use of Trans Epithelial Nerve Stimulation with the administration of a therapeutic injection, such as an immunization, or tissue sampling procedure such as deriving a blood sample. By such an arrangement the discomfort associated with these procedures may be considerably reduced or eliminated, thereby improving compliance with a range of medical procedures. To date TENS has not been used in such an arrangement, rather development in TENS technology has been aimed at improving its efficacy. Similarly injection technology developments have been orientated around reducing cross infection risks and accidental injury to operator or patient.

25. An apparatus for reducing pain or hemorrhage, the apparatus comprising:
-
a current generating device configured to generate an electrical output Trans Epithelial Nerve Stimulating (TENS) current;
an array of electrodes electrically coupled to the current generating device and configured to be placed around an injection location on the skin of a patient; and
a current applying device configured to apply the TENS current sequentially to the electrodes. - View Dependent Claims (26, 27, 28, 29, 30, 31, 32)

33. An apparatus for reducing pain or hemorrhage at an injection location on the skin of a patient, the device comprising:
-
a current generating device configured to generate first and second types of electrical output Trans Epithelial Nerve Stimulating (TENS) current;
an array of electrodes electrically coupled to the current generating device and configured to be placed around the location on the skin of the patient, the electrodes including a first group and a second group, the first group being configured to be disposed closer than the second group to the location on the skin of the patient; and
a current applying device configured to;
apply the first type of TENS current to the first group of electrodes; and
apply the second type of TENS current to the second group of electrodes. - View Dependent Claims (34, 35, 36, 37, 38, 39)

40. A method of reducing pain or hemorrhage of a superficial therapeutic injection or a superficial body tissue sampling, the method comprising the steps of:
-
placing an array of electrodes on the skin of a patient;
applying electrical output Trans Epithelial Nerve Stimulating (TENS) current to the electrodes; and
breaching the skin of the patient at a location within the array of electrodes. - View Dependent Claims (41, 42, 43, 44)
