Abstract: A menstruation periodic counter is provided with an indicator of a calendar, an indicator of a bodily temperature chart and temperature measuring time, an input switch for receiving numeral values, and an alarm mechanism for sounding at a time set by the input switch, and wherein the calendar indicator indicates through a cursor information concerning the days obtained from the data for indicating the bodily temperature chart. Automatic adjustment of the range sensitivity of the temperature sensor and correction of out-of-range values, based on expected basal bodily temperature period as predicted by the Ogino method is effected by microprocessor.

Abstract: This invention relates to an injector with a cartridge for a liquid medicine, which is suitable as a throwaway type or a re-use type, and especially displays remarkable effects at urgent occasions. This injector substantially comprises an injector tube housing a cartridge into a body thereof and a cylinder slidably supporting a piston such that it is not removed therefrom at its end portion and in the injector tube by its front half part. Further, the cartridge is equipped with a concave on its bottom and the piston is equipped with a convex on its head for engaging means. The needle portion comprises an injecting needle and a hollow needle inwardly extending from the needle. If the needle portion is urged while it is fitted to the injector tube, the hollow needle pierces the cartridge and reaches the liquid medicine in the cartridge. The cylinder is defined with a stopper at its circumferential edge to restrain the piston with respect to the cylinder.
