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.

Claims

1. A therapeutic injection or sampling device and process, comprising a means of generating an electrical output Trans Epithelial Nerve Stimulating current and means of applying this to a patients body part, in association with a carrier mechanism for a variety of therapeutic injection or sampling systems, such as a needle and syringe or blood sampling lance or device.

2. A therapeutic injection or sampling device and process, comprising a means of generating an electrical output Trans Epithelial Nerve Stimulating (TENS) current and means of applying this TENS current to a patient utilizing a glove carrying electrodes on its surface, whereby the TENS current can be applied to the patient around the desired injection or sampling site.

3. A therapeutic injection or sampling device which comprises at least three connected components, a TENS generating apparatus, two or more patient electrode contacts and an injection, or sampling system, such as a syringe and needle.
