Abstract: A therapeutic device and method for blocking pain in a patient's digit includes a ring-like vibratory element adapted to be fitted about the digit temporarily and controller coupled to the ring-like vibratory element for controlling its operation. By applying vibration to the patient's digit, pain transmission is blocked or lessened along the digit, allowing the patient or a caregiver to provide treatment to the digit with reduced pain, such as when a diabetic's finger is to be stuck for drawing blood for a blood sugar measurement). Moreover, if the digit is injured, the present invention can provide pain relief from the injury as well. Further, the invention can be applied to the digit in combination with other pain-reducing therapies, such as the application of ice, the application of topical analgesics, the application of local anesthetics, etc. The controller includes an on/off control switch and a switch for controlling the vibratory frequency.

Abstract: Cooling and heating eyeglasses have peltier chips mounted around at least a portion of the perimeter of the lenses that provides a cooling affect that reduces eyestrain and provides cooling relief to the user. A battery pack provides the electrical energy needed to energize the peltier chips. The battery pack is connected to a neck strap that allows the user to comfortably support the batteries. In another embodiment, a plurality of smaller batteries are used and disposed within the frame eliminating the need for an external battery pack. In another embodiment, side shields are also provide with peltier chips to further control the temperature especially around the user's eyes. Because the peltier can also provide heating, a user can also select heating if preferred. The cooling and heating glasses can be used for prevention and treatment of several eye diseases and oculopathies.
