An outside surface of the belt provides plural spaced apart elongate fasteners aligned with a longitudinal axis of the belt, each of the fasteners compris
A belt extends about the waist of a patient and is secured at a selected tightness thereon, the securing device being adjustable as to tightness. An outside surface of the belt provides plural spaced apart elongate fasteners aligned with a longitudinal axis of the belt, each of the fasteners comprising a first surface attachment element integral with the outside surface of the belt, and a second surface attachment element permanently fastened at one end of the first surface attachment element and extending longitudinally in removable, mutually engaged contact with the first surface attachment element. A fluid storing bulb has an inlet nipple adapted for receiving a fluid conduit for conducting a bodily fluid into the bulb, and has an outlet nipple adapted for expulsing the fluid collected. A stopper, temporarily seals the outlet nipple when it is not in use. An attachment band provides a loop adapted for receiving one of the second surface attachment elements for engaging the fluid storing bulb with the belt within reach of a person wearing the belt. A fluid conduit engages the inlet nipple of the fluid storing bulb at one end, and at the other end, the source of the bodily fluid.

An apparatus according to claim 1, further comprising a second pressure-pulse-wave sensor which is adapted to be pressed against the first artery of the subject and detects the first-artery pressure pulse wave generated by the first artery, wherein the first pressure-pulse-wave sensor is adapted to be worn on said portion of the subject that is more proximal to the heart of the subject than the first artery against which the second pressure-pulse-wave sensor is adapted to be pressed. 3. An apparatus according to claim 1, wherein the relationship checking means judges that the relationship between blood pressure and magnitude of pressure pulse wave is not appropriate, when a relative value between the change value of the pieces of pulse-wave-propagation-velocity-related information, determined by the propagation-velocity-related-information-change-value determining means, and the change value of the monitor blood-pressure values, determined by the monitor-blood-pressure-change-value determining means, does not fall within a normal range. 4. An apparatus according to claim 3, further comprising a normal-range determining means for determining, as the normal range, a narrower range when the monitor blood-pressure value used to determine the change value of the monitor blood-pressure values is lower than a prescribed danger value which indicates that the subject needs an urgent treatment, than a range determined thereby when the monitor blood-pressure value is not lower than the danger value. 5. An apparatus according to claim 1, wherein the relationship checking means comprises means for operating, when it is judged that the relationship between blood pressure and magnitude of pressure pulse wave is not appropriate, the relationship determining
