Abstract: A determination is quantitatively made of the severity of pain exhibited at a specified area on an animal by determining the magnitude of cooling required at the area of pain in order for the pain to be masked or made to disappear. The amount of cooling required for pain disappearance is considered directly related to the severity of the pain. Hence, by measuring the temperature depression required to mask the pain in a patient, an examiner can determine just how serious is the pain, and additionally provide guidance in the selection of a specific medicine. There is always some finite temperature depression required for true pain to disappear. Should the patient alleges that no pain relief is encountered by the cooling of the painful area, the examiner considers that the patient is faking his pain.

Abstract: Neurological testing apparatus by which the sense receptor's of a person can be tested. The apparatus is of a configuration to be held in the hand and includes a body having a front surface opposed to a rear surface to provide ample space for supporting a plurality of spaced apart covered substances thereon. The substances are each different from the other and each substance test one of a person's sense receptors. One of the members include a sweet tasting substance, another member includes a sour tasting substance, and another member includes a substance fragrant to a person's smell. Other substances include color and indicia. A protective cover is removably placed on the substance for testing the smell and taste. The testing apparatus further includes a sharp end opposed to a disk end for testing a person'sense of feel and peripheral vision.

Abstract: An oral inhalation apparatus having a flow responsive valve associated therewith for controlling the flow of medication from an aerosol canister into one's lungs. An aerosol canister is received within a housing and the outlet thereof is received within a tubular passageway so that when the canister is pressed down respective to the housing, the valve means associated with the canister is moved to the open position. A second valve means is positioned downstream of the canister valve means and is spring loaded into the normally closed position. When the patient places a mouthpiece of the apparatus within his mouth and inhales, a sail device is moved downstream in reaction to the flow of inhaled air, thereby moving the second valve to the open position which releases medication into the mouthpiece. Consequently, when the patient initially depresses the canister, thereby opening the canister valve, there is no flow from the canister.
