Fig. 1 is structured flowchart of the present utility model;
Wherein, 1-single-chip microcomputer, 2-charactron, 3-code translator, 4-latch, 5-hummer, 6-LED, 7-supervisory keyboard, 8-communication interface, 9-computer, 10-power supply.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail:
Cardiopulmonary resuscitation auxiliary electron metronome as shown in Figure 1, it is characterized in that: it comprises single-chip microcomputer 1, charactron 2, code translator 3, latch 4, hummer 5, LED 6, supervisory keyboard 7 and power supply 10, wherein, the buzzing control signal output terminal of described single-chip microcomputer 1 connects the control end of hummer 5, the LED flash signal output terminal of single-chip microcomputer 1 connects the control end of LED 6, single-chip microcomputer 1 control end connection control keyboard 7, the decoder control signal output terminal of single-chip microcomputer 1 connects the control end of code translator 3, the latch-control signal output terminal of single-chip microcomputer 1 connects latch 4 control end, signal input part is selected in the position of the signal output part connection charactron 2 of described code translator 3, the section of the signal output part connection charactron 2 of described latch 4 selects signal input part, described power supply 10 is powered to single-chip microcomputer 1.Described hummer 5 is passive hummer.
In technique scheme, latch 4 logarithmic code pipe 2 carries out Duan Xuan, and (Duan Xuan is the individual position being controlled charactron in the figure place of charactron by latch, ten, the Signal transmissions of hundred, signal is made to pass in required figure place, the light on and off of figure place on charactron are controlled) by latch, code translator 3 logarithmic code pipe 2 carries out position choosing, and (position choosing is that a kind of signal of code translator to single charactron controls, carried out the control of light on and off again by the single body (single charactron one has 7 LED) of code translator to single charactron after the Duan Xuan of latch completes, thus can combine and demonstrate required numeral, but because latch can only control single charactron, so when the writing of program, allow need the figure place of display to replace light on and off when the multiple figure place of numeral method, display while the interval of period allows the naked eyes of people can't see just can to realize long number), finally allow charactron 2 can show the ongoing frequency of hummer 5, hummer is divided into passive hummer and active buzzer two kinds, and here we select be passive hummer, because active buzzer only just can send sound with connecting direct supply, but sound is immutable, and the sound signal ability sounding that passive needs are certain, and different sound can be sent, common ring is different from because the utility model needs to produce a prompt tone after 30 rings, so we adopt be that passive hummer is used as sound source.Consider the factors such as environmental noise in addition, hummer 5 sound can be divided by partes tecta, the utility model option and installment LED 6, along with a sound flash red LED of hummer 5, within the 5 second time stopped, red light Chang Liang does not glimmer, and makes the effect that also can play auxiliary rescue personnel in the environment that noise is larger.
In technique scheme, it also comprises communication interface 8 and computer 9, and the communication ends of described single-chip microcomputer 1 connects computer 9 by communication interface 8.
In technique scheme, the beep frequencies of described hummer 5 is consistent with the flicker frequency of LED 6, and the buzzing of hummer 5 is synchronous with the flicker of LED 6.
In technique scheme, the beep frequencies of described hummer 5 and the flicker frequency of LED 6 are 120 times per minute.
In technique scheme, described power supply 10 is the lithium battery of 5V.Because the utility model needs to carry with, then the lithium battery of selection 5V is used as power supply 10.
When the utility model uses: by computer 9 by a whole set of steering logic write single-chip microcomputer 1, single-chip microcomputer 1 is according to the frequency buzzing of steering logic control hummer 5 according to 120 beats/min, simultaneously, LED 6 synchronous flashing red light, rescue personnel carries out external chest compression according to this frequency, hummer 5 is every suspends five seconds for 30 times (often rings and finally in 30 times drips sound ending several times with not same tone, and no matter hummer 5 flicker frequency is how many, all to suspend five seconds 30 times in flicker), now LED 6 red light Chang Liang does not glimmer, now rescue personnel stops external chest compression, carry out 2 artificial respirations, then the circulation of 30 times is continued, pressing and ventilatory frequency were so both ensure that, control again and press break period.Current compression frequency information is shown by charactron 2 by single-chip microcomputer 1, when needs adjust compression frequency, adjusts the steering logic in single-chip microcomputer 1 by supervisory keyboard 7.
After rescue personnel uses the utility model, by experiencing metronome frequency to strengthen the power of a test to frequency, can very accurately by external chest compression frequency control at a proper range, control ventilation frequency, avoid hyperventilation, thus effectively improve cardiopulmonary resuscitation quality.
The content that this instructions is not described in detail belongs to the known prior art of professional and technical personnel in the field.
