Further, described probe comprises probe top and probe bottom, and between the two by being threaded, the inside of probe bottom is provided with pick off, and pick off exposes from the end sections of probe bottom.
Further, also be provided with the wiring hole that is used for described sensor lead on the described probe bottom.
Further, described pick off is a physiological pressure transducer.
Further, the described card of going up comprises first-hand pommel and following pressure side, and following pressure side is provided with side and transfers wheel, and side transfers that the form with gear-tooth bar matches between the rear portion of wheel and described feeler lever, and it is the extension elongation of the described feeler lever of scalable that the rotating side accent is taken turns.
Further, described card down comprises second-hand's pommel and last folder end, and folder end and described clamping part between the pressure side down are to meet the arc design of human engineering on this.
Further, also be provided with on the described pressure side down and raise wheel, raise wheel and comprise knob and threaded mandrel, between the upper surface of this threaded mandrel and described down pressure side by being threaded, and the lower end of threaded mandrel leans on described feeler lever, is provided with support spring between the lower surface of described feeler lever and described pressure side down.
Further, described top and bottom of going up the axis part of blocking and blocking down are provided with groove, and described Spring Card is a U type structure, and it is installed in the groove, so that described card and the following card maintenance clamped condition gone up.
The present invention can install two even plural side by side pick off simultaneously, is used in the radial artery place and records multiple-point pulse wave simultaneously, because two test points distance is very near, so the point-to-point transmission blood vessel can be approximate with straightway, to obtain accurate PWV.In addition, be beneficial to install among the present invention and can measure pulse wave of multiple points simultaneously, it is convenient to practical operation, has improved certainty of measurement.

The specific embodiment
As shown in Figure 1 to Figure 3, only be provided with a probe and pick off in the present embodiment.
A kind of fixing device for radial pulse wave detection sensor of the present invention, comprise and be used for going up card 1 and blocking 2 down of clamping wrist, both are connected by rotating shaft 3, the top and bottom of the axis part of last card 1 and following card 2 are provided with groove, in this groove, be installed with Spring Card 4, this Spring Card 4 is a U type structure, and it makes that going up card 1 keeps clamped condition with following card 2.Last card 1 is provided with a feeler lever 5 that extension elongation is adjustable, the front end of feeler lever 5 is provided with probe 8, probe 8 comprises probe top 81 and probe bottom 82, between the two by being threaded, the inside of probe bottom 82 is provided with pick off 10, and pick off 10 exposes from the end sections of probe bottom 82, and probe also is provided with the wiring hole that is used for pick off 10 lead-in wires on the bottom 82, and wherein pick off 10 is a physiological pressure transducer.
Among the present invention,, make that pick off 10 all can fit on the wrist best position, has improved its practicality by setting out the adjustable probe 8 of length-adjustable feeler lever 5 and volume under pressure, and improved the accuracy of measuring for different measured's wrist shapes.
As shown in Figure 4, be provided with two probes and pick off in the present embodiment.
In order to measure PWV (pulse wave velocity), and improve the accuracy of its measurement, be provided with two probes in the present embodiment, and on two pick offs.
Each parts of present embodiment all with embodiment 1 in identical, difference is: on block two cover feeler levers, probes, the pick off that has side by side, and it has independently side transfer wheel to regulate the extension elongation of feeler lever respectively, raises wheel 7 and regulate the degree that compresses that probe puts on wrist.
