Description

A kind of volume pulsation wave acquisition processing device being positioned on finger

Technical field

This utility model relates to medical instruments field, is specifically related to a kind of volume pulsation wave acquisition process being positioned on finger Device.

Background technology

Photoplethysmographic (PhotoPlethysmoGraphy, PPG) is that excuse me, and electric hand section detects in biological tissue A kind of non-invasive detection methods of volumetric blood change.

When the light beam of certain wavelength is irradiated to finger tip skin surface, light beam will be sent to light by transmission or reflection mode Electricity receptor.In the process due to the attenuation by absorption effect by finger tip integumentary musculature and blood, the light that detector detects Intensity will weaken.Wherein light is absorbed and is to maintain invariable and skin in whole blood circulation by integumentary musculature tissue etc. Interior volumetric blood changes in pulsation under key role.The most absorbing amount of peripheral blood capacity is the most maximum when the heart contracts The light intensity detected is minimum；And the light intensity maximum that contrast detects when diastole, make optical receiver receive Light intensity therewith in pulsating nature change this intensity variation signal is converted into telecommunications.

Volume pulsation wave datum participates in the diagnosis of a lot of diseases, such as sleep apnea syndrome (OSAHS) etc..And mesh On front market, the device of collection PPG signal is commonly included in wrist and wears harvester body and acquisition probe, but the two needs Use complicated wire to connect, bring inconvenience, and user or other people in side easily imprudence is collided or pullled and leads Line, the most easily makes acquisition probe offset, affects measurement result.

Monitor, judge that sleep apnea syndrome (OSAHS) typically requires long-time collection PPG signal, as used Wearing harvester before person's sleep, take off morning, the data collected user the most whole night process, calculating etc., Finally draw concrete conclusion；If then using the harvester that above-mentioned existing market is general, then user is in order to make collection Device does not offsets, tests accurately, the most for a long time, stays up the most whole night, therefore, brings great inconvenience for user.

At present, rarely have by being combined, with processing means, the photoelectricity volume arteries and veins effectively gathered to same device by gathering Fight ripple acquisition process fingerstall.Publication No. is that the Chinese patent application of CN 105769139A discloses the pulse letter being positioned on fingernail Number gather and data wireless base station apparatus, it includes pulse transducer, untight clamping flexure strip, hinge, untight finger Portion's fixed cover, signal conditioning circuit module and single-chip microcomputer gather sending module, and clamping flexure strip can be by pulse transducer Being stably fixed on fingernail, clamping flexure strip is connected by hinge with finger fixed cover, and can turn with the activity of finger Dynamic.Device that it is a hollow, that finger can pass through, overall structure is like finger-shaped, but through the hole of finger in the middle of this device Size is the most fixing, and user individual variation is big, and the thickness length difference of finger is relatively big, then be easily caused pulse transducer with Finger contact is unstable or insecure thus greatly affects the accuracy of data acquisition.Additionally, the fine structure of this device, system Making complexity, certain parts damages is non-exchange, needs to abandon whole device, i.e. allows to change, and its operation is the most more complicated, Time cost is high.Therefore, the practicality of this device is not strong, is unsuitable for clinical practice.
