The specific embodiment
As shown in Figures 1 to 4, beat pulse blood pressure intensity of wave of the present utility model and vascular width measure pick off comprise shell 31,32, sensor probe 20, circuit board (not shown) and go between 100.Be the perspective exploded view of pick off of the present utility model as shown in Figure 5, wherein sensor probe 20 is a twin beams elastomer structure, and twin beams is a symmetrical structure.As shown in Figure 6, sensor probe 20 is many probe twin beams elastomer structures, 211～217 be example with 7 probes among the figure, following accompanying drawing is that example illustrates structure of the present utility model with 7 probes all, but many sonde configurations of the present utility model are not limited only to 7 probes, this is a preferred structure, is not restriction of the present utility model.As Figure 12, Figure 14 and shown in Figure 15, many probe twin beams elastomer structure 20 its each 211～217 pairs of probes should have two beam 241A～247A, 241B～247B, two beam 241A～247A of each probe 211～217 correspondence, be symmetrical arranged a two resistance silicon foil gauge 411A～417A on 241B～247B, 411B～417B, 411C～417C, 411D～417D, a pair of pair of resistance silicon foil gauge that described each probe is corresponding (411A for example, 411B, 411C and 411D) constitute a Wheatstone bridge, measure the pressure of each probe vascular of testing by the variation of monitoring described bridge voltage.
As Fig. 9, Figure 12 and shown in Figure 14, two beams that its each probe of twin beams elastomer structure of the present utility model is corresponding include a fan-shaped part and a bar shaped part, because the gross area of probe is small-sized, 6mm*6mm for example, if be divided into 7 probes, the width of each probe has only about 0.6～0.8mm, if adopt the bar ellbeam because the restriction of width, the elastic force scope also can be restricted, therefore this utility model adopts the combining form of a fan-shaped part and a bar shaped part can increase the area of beam, thereby can increase elastic bearing capacity scope.
As Fig. 9, Figure 12 and shown in Figure 13, because the length of fan-shaped each beam that adds the bar shaped girder construction is all different with area, the degree that is subjected to deformation behind the identical pressure is also different, this utility model on two corresponding beams of each probe in addition symmetric design reinforcement 231A～237A, 231B～237B, be used for overcoming seven probes 211～217 when being subjected to identical power because the elastomeric beam 231A～237A of twin beams, 231B～237B length is different with area and produce different skews, by changing the method for the length of reinforcement on each beam, reach and be subjected to identical pressure to produce identical skew, thus guarantee seven probes after being subjected to identical power to produce skew still at grade.In addition, because the requirement on machining accuracy of probe and beam is all very high, (for example a kind of preferred probe quantity is 7 and size is smaller, the width of each probe is 0.5-1.0mm, and the distance between the adjacent probe is 0.1-0.5mm), the thickness of beam also very thin (usually less than 2mm) adds easy cutting in man-hour and has been easy to deviation, and this local reinforcement can also overcome the above-mentioned problem that produces distortion owing to the elastomer beam is long.In use, because beam is thinner, may reverse behind the deformation staggered floor up and down, this structure can play simultaneously again and prevent that probe and beam deformation from being the position skew or reversing, and also is a significant improvement of the relative prior art of this utility model.
As Fig. 2, Fig. 4 and shown in Figure 7, the sonde configuration 211～217 on boss structure 311,321 on the shell 31 and 32 and the seven probe twin beams elastomers matches, and plays the protection that probe is subjected to the side direction overload pressure.
As Fig. 5, Figure 10 and shown in Figure 11, also be provided with one below the described twin beams elastomer structure and prevent to pop one's head in and be subjected to pressing down of overload pressure and stop crossbeam 50, described pressing down stops to have deformation gap 51 between crossbeam and the described twin beams elastomer structure.Because operate miss is stressed when excessive probe 211～217; the elastomeric beam 231A～237A of twin beams, 231B～237B become overload variation allowed band in the electrostrictive strain resistance type and promptly press down in the type change gap 51 that stops beam 50 designs; just pressed down the prevention that stops beam 50, played pressure overload protection.
As shown in Figure 8, boss structure 221A～227A, 221B～227B on structure 312,312 on the shell 31 and 32 and the seven probe twin beams elastomers match, and play to prevent to transship pulling force and 211～217 protect popping one's head in.
As shown in Figure 5, the preferred structure of circuit board section can comprise: two resistance connecting plates 61,62 that are used for the strain resistor of sensor probe 20 is connected to temperature-compensation circuit plate 70, temperature-compensation circuit plate that is used for temperature-compensating 70, a plugboard 90 and an amplifier plate 80 that is used for signal is amplified and outputs to described lead-in wire that is used for the signal after the compensation is sent to amplifier plate 80.
