Abstract
The invention discloses a heart function sensor for monitoring heart functions. The heart function sensor consists of a shell, a lead, conductive electrodes and a high polymer piezoelectric material which is filled between the electrodes. The sensor can be prepared into films with any shape and unequal areas. A vibration signal generated by heart beating can be conducted to various parts through human tissues; and tissues of various parts of a human body are different, and the distances between various parts and the heart are different, so the vibration of different degrees can be generated on various parts of the body surface of the human body. The sensor is attached to the body surface of the human body, and senses the vibration of various parts of the body surface so as to ensure that the high polymer piezoelectric material vibrates. The high polymer piezoelectric material converts the vibration into a charge signal which is output by the lead. Single or multiple sensors can be adhered to the body surface according to requirements; and a curve which reflects the heart functions can be obtained after the output charge signal of the sensor passes through the subsequent processing circuit. The curve can be applied to heart rate measurement, heart function analysis, clinical diagnosis and the like.

[technical field]
The present invention relates to sensor technical field, be specifically related to a kind of cardiac function pick off that is used for the cardiac function monitoring.
[background technology]
Heart disease is one of principal disease of serious threat human health and life, and along with China's aged tendency of population, the ratio of heart disease is increasingly high.One of major technique that is used for the cardiac function monitoring is an electrocardiogram, and electrocardiogram is the science that the body surface potential difference that the cardiomotility process is produced is noted and explained.
Cardioelectric monitor method commonly used at present is to adopt disposable Ag/AgCl to paste electrode (foamed materials of core is inhaled has electrolyte), sticks on the body surface characteristic portion.Kind electrode belongs to disposable product, can not reuse.And the built-in electrolyte of electrode, electrolyte has corrosivity, if life-time service can make the local skin pruritus even festers.Simultaneously, settle the position of electrode,, can cause electrode loose contact if skin does not clean or scurf, hair are arranged.
[summary of the invention]
Main purpose of the present invention provides a kind of simple and effective cardiac function monitoring means.
Be to realize above-mentioned purpose, the present invention provides a kind of cardiac function pick off, is made up of shell, lead-in wire, conductive electrode and the high polymer piezoelectric material that is filled between the electrode.High polymer piezoelectric material comprises Kynoar (PVDF), polyvinyl fluoride (PVF), polrvinyl chloride (PVC) etc., is a kind of flexible piezoelectric material.This piezoelectric can produce charge signal when vibration.
The vibration signal that produces during heartbeat can pass through tissue and conduct to each several part, because the tissue of health each several part is different, each several part is different with distance between heart, and each position of body surface can produce vibration in various degree.This pick off is attached to body surface, and the vibration at each position of pick off sensing body surface makes high polymer piezoelectric material vibrate.High polymer piezoelectric material changes this vibration into charge signal, by lead-in wire output, through follow-up treatment circuit, just can obtain reflecting the curve of cardiac function.Can paste single or a plurality of pick offs at body surface according to demand; The cardiac function curve that single-sensor obtains can be applied to heart rate measurement, cardiac function monitoring etc., and the cardiac function curve that a plurality of pick offs obtain can be applied to clinical diagnosis, cardiac function analysis etc.
The invention has the beneficial effects as follows:
This heart function pick off adopts high polymer piezoelectric material as sensing material, has the good characteristic that response speed is fast, highly sensitive and the linearity is good, has guaranteed cardiac function monitoring accuracy and accuracy.Simultaneously, this heart function pick off is prone to process the thin film that arbitrary shape and area do not wait, and is in light weight, very soft, and can be repeatedly used.This pick off only need stick on body surface and get final product in use, can not cause damage to human body skin.
[specific embodiment and description of drawings]
The application's characteristic and advantage will be through embodiment, in conjunction with the accompanying drawings.
Fig. 1 is the sketch map of cardiac function pick off, is made up of shell, lead-in wire, upper/lower electrode and high polymer piezoelectric material, and high polymer piezoelectric material is filled between top electrode and the bottom electrode.This cardiac function pick off is a film shape, and is very soft, and very durable.
Fig. 2 is the sketch map that three cardiac function pick offs is used for the cardiac function monitoring.Three pick offs are sticked on the front, and the output charge signal of pick off is connected to treatment circuit through lead-in wire, through processing circuit processes, just can obtain cardiac function curve, shows through display screen.
Fig. 3 adopts the resulting cardiac function curve of embodiment shown in Figure 2.This curve can be applied to heart rate measurement, cardiac function analysis, clinical diagnosis etc.
Above content is to combine a kind of embodiment to the further explain that the present invention did, and can not assert that practical implementation of the present invention is confined to these explanations.For the those of ordinary skill of technical field under the present invention, under the prerequisite that does not break away from the present invention's design, can also make some simple deduction or replace, all should be regarded as belonging to protection scope of the present invention.
