Description
Technical field
The present invention relates to biomedical engineering field, particularly a kind of pulse condition vertical pressing driver.
Background technology
Since the 1950's, vast scientific research scholar, all having carried out a large amount of research work aspect the pulse conditions such as Sphygmology, pulse-taking method, clinical diagnosis and experiment, has obtained larger progress.Up at present, the research that objectifies of pulse condition mainly concentrates on the development of electropulsograph.
Englishman Marey has developed the earliest lever pulse transducer and has recorded radial artery pulse wave, within 1860, occurs first that lever and pressure drum describe sphygmogram, and 1895 start to adopt the mode of transducing, have occurred lever optics pulse describer.The fifties, Chinese scholar peach blossom face of a beauty referred to lever sphygmometer the research of pulse wave spectrum first.From the seventies so far, research worker has been developed miscellaneous transducer with the finger of simulation traditional Chinese medical science feeling the pulse, gathers pulse signal record.
The cunkou pulse of the traditional Chinese medical science is divided into cun,guan,chi three parts, take processus styloideus radii as labelling, and its inner side, for closing, is very little before closing, and after closing, is chi, and two handss respectively have cun,guan,chi.Need to be by three places be applied to the pulse condition that different pressure is surveyed different pressures during feeling the pulse, it is the touching, pressing and searching with fingers for pulse feeling feeling the pulse fingering in Chinese materia medica meaning, gently finger power by being " act " on skin, heavily refer to power by between muscles and bones for by, light not heavy moderate by end finger power between " act " and " pressing " refers to that power is " seeking ", while being feeling the pulse with different by the end finger power method of feeling the pulse.
The finger Shi doctor that feels the pulse, by finger, applied different pressure and realized in the past, then along with transducer, simulate the development of traditional Chinese medical science feeling the pulse technology, finger applies different pressure and by technological means, is replaced in this situation, adopts special equipment to complete touching, pressing and searching with fingers for pulse feeling obviously more and more necessary.
Existing related invention patent and research have realized Pulse signal acquisition to a certain extent, but aspect simulation finger feeling the pulse " touching, pressing and searching with fingers for pulse feeling ", also exist inaccuracy and can not layering etc. the shortcoming such as deficiency and the excessive difficult microminiaturization of volume, as " a kind of Chinese medicine pulse detection system " pulse signal harvester (CN201310418535) adopts ring-type or cyclic structure, be wound in around wrist, can not realize the touching, pressing and searching with fingers for pulse feeling maneuver that the traditional Chinese medical science is felt the pulse; Multistage combined traditional Chinese medical pulse manifestation collecting device (CN201310499382) and for example, although be provided with one " liftable arm ", but can only realize roughly " very little, pass and chi " three whole feeling the pulse and regulate pressure, can not realize three pressure adjusting and every tiny position pulse feeling pressure adjustings separately, cannot realize the accurate layering of feeling the pulse in modern pulse-taking, and lack motility; Also as full-automatic feedback formula region pulse condition collecting device (CN203388839U), be provided with " pulse condition simulation rod (5 millimeters * 5 millimeters of external diameters) ", but complex structure lacks application flexibility, and can only realize roughly pressure and regulate, cannot realize the accurate layering of feeling the pulse in modern pulse-taking.
Summary of the invention
For overcoming the above problems, the present invention proposes a kind of pulse condition vertical pressing driver, realizes cunkou pulse is applied to different pressures, measures the vein information of different depth.
A kind of pulse condition vertical pressing of the present invention driver, comprises that array presses sensor probe 1, piston 2, plunger lock device 3, drive tank 4, tension spring 6, cap 5, trachea 8 and charge and discharge control device 9; Described piston 2 lower ends are inserted array and are pressed in the groove of sensor probe 1 upper surface, described array is pressed sensor probe 1 and is fixedly connected with described piston 2 lower ends by screw 1A, described piston 2 is nested with tension spring 6 to be arranged in the cavity that drives tank 4, described tension spring 6 one end are fixed on piston 2 upper ends, and tension spring 6 other ends are fixed on the medial surface of described cap 5; Described cap 5 is fixed on the top that drives tank 4 by screw 5A, on described cap 5, be provided with the ventilating column 7 of hollow, described ventilating column 7 by trachea 8 with charge and discharge control device 9 and be connected, described in charge and discharge control device 9 and comprise micro electromagnetic air valve, Mini-size inflation pump and controller; Described controller is connected with Mini-size inflation pump with Electromagnetic Drive piece 32A, the micro electromagnetic air valve of plunger lock device by conductor cable.
The present invention produces attraction magnetic force by the Electromagnetic Drive piece of controller control piston lock, attract locking bolt away from the sawtooth with unclamping the card wing, then charging and discharging control device inflation makes to drive pressure tank to increase, promotion piston moves downward, the Electromagnetic Drive piece that is increased to a certain setting value Time Controller control piston lock when pressure does not produce attraction magnetic force, at this moment locking bolt is blocked the sawtooth of the card wing under the natural elasticity effect of compression spring, piston is settled out, " touching++++++++pressing and searching " dynamics of realization increases and " searching and pressing with fingers for feeling pulse " operation, be convenient to Pulse signal acquisition and high frequency Pulse signal acquisition under a certain stable " touching++++++++pressing and searching " dynamics.Electromagnetic Drive piece by controller control piston lock produces attraction magnetic force, attract locking bolt away from the sawtooth with unclamping the card wing, and exit by charging and discharging control device, make to drive pressure tank to reduce, by tension spring pulling force, produce the active force that upwards pulls piston, the Electromagnetic Drive piece that is reduced to a certain setting value Time Controller control piston lock when pressure does not produce attraction magnetic force, at this moment locking bolt is blocked the sawtooth of the card wing under the natural elasticity effect of compression spring, piston is settled out, " touching++++++++pressing and searching " dynamics that realizes reduce and " act is sought " operation and a certain setting pressure under Pulse signal acquisition and high frequency Pulse signal acquisition.This invention can accurately realize " touching++++++++pressing and searching " pulse-taking at " very little, pass and chi " three positions and " touching++++++++pressing and searching " the accurately layering at " very little, pass and chi " three positions flexibly.
