A device for securing a living body by pressing includes a living body pressing air bag, a curled elastic member of an approximately cylindrical shape, disposed on the outside of the living body pressing air bag and changeable in size in a radial direction, and a curled elastic member pressing air bag, disposed on the outside of the curled elastic member and inflated to press an outer peripheral surface of the curled elastic member inward to reduce a diameter of the curled elastic member, to thereby press the living body pressing air bag against the living body via the curled elastic member. This can provide a living body pressing and securing device provided with a novel automatic cuff winding mechanism that can simplify and downsize the winding mechanism, hardly causes skin tension on the body surface, and ensures uniform winding strength over the entire surface of the pressed site.

In wrapping a blood pressure measurement cuff enclosing therein a bladder, which is inflated when supplied with air, around a region for measurement, first, a predetermined amount of air is supplied to the bladder and then enclosed therein. Then, the blood pressure measurement cuff is wrapped around the region for measurement of a subject for the purpose of measuring his/her blood pressure. During this wrapping process, relative variations in the pressure in the bladder are sequentially detected. The time period in which the detection results indicate that the variation has not reached a predetermined threshold value, the wrapping proceeds. When the detection results indicate that the variation has reached the predetermined threshold value, the wrapping is terminated.

A blood pressure monitor includes a main unit casing placed on a table, a living body insert portion casing of an approximately cylindrical shape, positioned on the main unit casing in a non-use state and having a cuff arranged on its inner peripheral surface, the cuff having a hollow portion to which an upper arm of a subject is inserted, and a connection mechanism for connecting the living body insert portion casing with the main unit casing in a movable manner such that, upon application of the cuff to the subject, the living body insert portion casing can move to come closer to the subject than the main unit casing. Thus, a blood pressure monitor provided with an automatic cuff winding mechanism enabling measurement of blood pressure with high accuracy, not giving unnecessary pain to the subject, and allowing measurement with an unconstrained posture can be provided.

Prior to blood pressure calculations, air is enclosed in a blood pressure measurement bladder to be wound and mounted around the region for measurement, in advance. By referring to the variation in the pressure therein, the circumferential length of the region for measurement is detected based on the variation in the pressure therein during the winding correction determination process for the region for measurement. Then, the process enters blood pressure measurement, and the blood pressure measurement bladder is pressurized or depressurized. The pressure in the blood pressure measurement bladder is detected. A blood pressure based on the detected pressure is calculated according to the circumferential length of the region for measurement which has been detected in advance.
