Abstract
Maximal oxygen uptake is one of leading indicator evaluating hale and hearty degree.Existing maximal oxygen uptake assessment instrument can not be got rid of due to individual variation, some people when hypoxic condition, due under endocardium lactic acid pile up, ATP synthesizes reduction, produces myocardiac inhibition, causes bradycardia, if calculate maximal oxygen uptake according to cardiotachometer this moment, numerical value is just obviously higher.In order to reduce error, the present invention installs blood oxygen saturation checkout gear and blood oxygen saturation and heart rate proportioning circuit in existing maximal oxygen uptake assessment instrument.Like this, just solve the problem of two aspects: heart rate corresponding when both can judge that hypoxic condition occurs, avoid calculating maximal oxygen uptake according to low heart rate, meanwhile, the degree that the oxygen in suction body is utilized by blood can be monitored again, the collaborative body constitution judging measured.
Description
Technical field
The present invention relates to a kind of electronic installation of maximal oxygen uptake assessment instrument, especially a kind ofly reduce maximal oxygen uptake measurement error and show the device of blood oxygen saturation.
Background technology
Operationally, Schilling measured carries out the motion of some strength to existing maximal oxygen uptake assessment instrument, then records post exercise heart rate, then calculates maximal oxygen uptake according to cardiotachometer.Its advantage is that measurement is convenient, apparatus is terse, is conducive to popularizing.But, from motion time investigate health take the photograph oxygen process: when quantity of motion is larger, oxygen consumption is violent, there is hypoxia phenomenon in body, what first occur during hypoxia is that compensatory heart rate accelerates, and heartbeat and cardiac output increase, and blood circulation is with the deficiency of the compensatory oxygen content of hyperkinetic state.The maximal oxygen uptake now calculated according to cardiotachometer is more correct., due to individual variation, some people is when hypoxic condition, and because lactic acid under endocardium is piled up, ATP synthesizes reduction, produces myocardiac inhibition, causes bradycardia, if calculate maximal oxygen uptake according to cardiotachometer this moment, numerical value is just obviously higher.
Summary of the invention
In order to reduce error, the present invention installs blood oxygen saturation checkout gear and blood oxygen saturation and heart rate matching device in existing maximal oxygen uptake assessment instrument.Like this, just solve the problem of two aspects: heart rate corresponding when both can judge that hypoxic condition occurs, avoid calculating maximal oxygen uptake according to low heart rate, meanwhile, the degree that the oxygen in suction body is utilized by blood can be monitored again, the collaborative body constitution judging measured.
Concrete scheme provided by the invention is: 5 functional units are formed a system (see Fig. 1).5 functional units are respectively: blood oxygen probe 1, blood oxygen saturation monitoring circuit 2, proportioning assembly 3, heart rate input module 4, display module 5.
Blood oxygen probe 1 adopts infrared emission-receptor, and the blood flow under detection finger skin is containing oxygen situation.Infrared emission-receptor can adopt dual wavelength, also can adopt three wavelength.Its output signal delivers to blood oxygen saturation monitoring circuit 2.Blood oxygen saturation monitoring circuit 2, according to the signal from blood oxygen probe 1, is converted to corresponding blood oxygen saturation digital, is input to proportioning assembly 3.Meanwhile, heart rate input module 4 is converted to number the heart rate signal in maximal oxygen uptake assessment instrument, is input to proportioning assembly 3.Proportioning assembly 3 is analyzed the blood oxygen saturation numerals sum heart rate number inputted simultaneously, judges the heart rate not producing myocardiac inhibition, is delivered in maximal oxygen uptake assessment instrument by this heart rate number, and blood oxygen saturation number is delivered to display module 5 shows.
The invention has the beneficial effects as follows: when hypoxic condition occurs, the heart rate of generation myocardiac inhibition can be screened out, avoid the error of calculation of maximal oxygen uptake.Further, the blood oxygen saturation data of measured can be shown simultaneously.

Detailed description of the invention
Overall structure block diagram of the present invention, shows in FIG.
In Fig. 1, frame 1 is blood oxygen probe 1, and frame 2 is blood oxygen saturation monitoring circuit 2, and frame 3 is proportioning assemblies 3, and frame 4 is heart rate input modules 4, and frame 5 is display modules 5.
What blood oxygen probe 1 was arranged on maximal oxygen uptake assessment instrument holds on handle, corresponding to finger position.Blood oxygen probe 1, by infrared emission-receptor, detects the blood flow under finger skin.Blood flow containing oxygen situation, affect the intensity of infrared light, thus the intensity of impact output signal, this signal passes through the delivery outlet H1 of blood oxygen probe 1, is transported to blood oxygen saturation monitoring circuit 2.Signal intensity is converted to number by blood oxygen saturation monitoring circuit 2, flows to proportioning assembly circuit 3 by delivery outlet Z1.Now, proportioning assembly 3 also simultaneously by from heart rate input module 4 delivery outlet P1, receives heart rate signal.Microprocessor in proportioning assembly 3, the two paths of signals of input is analyzed, screen out the heart rate that there occurs myocardiac inhibition, guarantee that the heart rate of normal physiological activity passes through, and calculated by the heart rate signal input K that delivery outlet h is transported to maximal oxygen uptake assessment instrument.Meanwhile, data are transported to display module 5 by output data line a, b, c, d, e, f, g of proportioning assembly 3, carry out special display.The input port P0 of heart rate input module 4, receives the original signal being derived from maximal oxygen uptake assessment instrument handle.
Shown in Fig. 2, it is an embodiment of blood oxygen probe 1.In this embodiment, D1, D2 are infrared light emission pipes, are driven by transistor Q1 and Q2, and the wavelength of transmitting is 595nm and 890nm respectively.Also can at the infrared light emission pipe of a 735nm in parallel on D2 or D1.D3 is infrared acceptor, and the wave-length coverage of reception is 660nm to 940nm.What infrared light emission pipe and infrared acceptor were arranged on maximal oxygen uptake assessment instrument holds on handle, corresponding to finger position.Also can be clipped on the ear-lobe of user in the mode of ear clip.The infrared light that infrared light emission pipe is launched, through the blood flow under skin, after reflection or transmission, is received by infrared acceptor.The signal that infrared acceptor receives, input ic IC1, then exports via H1 end.
Fig. 3 is an example of blood oxygen saturation monitoring circuit.From the signal of blood oxygen probe 1, be input to IC 2 from H1, after being converted to number, flow to proportioning assembly 3 by port Z1.
Fig. 4 is an embodiment of proportioning assembly 3.Two input ports are had, a signal received from blood oxygen saturation monitoring circuit Z1 port in this embodiment; Another receives the signal from heart rate input module 4 output port P1.This two paths of signals is respectively by after IC3 and IC4 process, enter microprocessor IC5 simultaneously, software in IC5 differentiates two paths of signals, analyzes, screen out the heart rate that there occurs myocardiac inhibition, allow uncontrolled heart rate signal pass through, and be transported to the heart rate signal input K of maximal oxygen uptake assessment instrument via delivery outlet h.The numerical value of blood oxygen saturation is converted to number by microprocessor IC5, exports, remove Control Items 5 from a, b, c, d, e, f, g port.
Fig. 5 is an embodiment of heart rate input module 4.The original signal being derived from maximal oxygen uptake assessment instrument handle enters IC6 from input port P0, exports proportioning assembly 3 to after treatment from port P1.
Fig. 6 is an embodiment of display module 5.The each port level of a, b, c, d, e, f, g from display module 5, enters the IC7 of display module 5, goes to drive display screen to manifest digital character by IC8, IC9.
