The operation principle of this output circuit is: under the control of microcomputor program,, regularly change the data that write each latch according to the sequential requirement of strictness, so that change the level of each latch outfan, as latch J
3With the level of KL and the joining outfan of KR according to specific time sequence from low to high, from high to low variation just forms the pulse output of characteristic frequency, J
1With the level step-down of the outfan that connects with display lamp the time, corresponding display lamp is bright, when uprising, display lamp goes out; J
2Thereby the different high or low level of 7 outfans seven segment code of just forming charactron demonstrate corresponding digital; J
1Start soniclizer with the level of the joining outfan of soniclizer during by low uprising, close nebulizer during by high step-down.
The specific operation process of Computerized medical instrument for respiratory system of the present invention is as follows: when the instrument energized, be in reset mode, charactron is shown as " 00 ", and all display lamps do not work entirely, does not have electric pulse output, and soniclizer is not worked yet.At this moment by " number of times (+) " key, CPU by data/address bus to latch J
2Write the seven segment code of " 3 ", make charactron show " 03 ", simultaneously, CPU is to latch J
3Write corresponding data, make J
3Pulse output end according to the repetition rate output pulse signal of per minute 3 times.After this, whenever by " number of times (+) " key once, then the numeral that shows of charactron adds 1, when showing " 20 " till, whenever press once " number of times (-) " key, the digital demonstration subtracts 1, till being kept to " 00 ", simultaneously, the output pulse recurrence frequency is done corresponding increase and decrease, so utilize " number of times (+) " and " number of times (-) " these two keys, can be in the scope of per minute 3-20 time the repetition rate of any selection electric pulse stimulation, and show its corresponding digital by charactron.From latch J
3The pulse signal of output is through pulse amplifier KL(or KR) amplify the back and swash acupuncture point relating to human body by the external electrode deburring, impel the breathing diaphragm pacing, it stimulates power can be by output L(or output R) the knob adjusting.When pressing " spray medicine " key, CPU passes through J
1Corresponding outfan send " spray medicine " order, then soniclizer is activated, and the medicament in the medicine glass is atomized into the droplet of diameter 0.7-5 μ m immediately, by leading the ejection of medicine corrugated tube, enter patient's respiratory tract, directly little airway and the alveolar to the patient produces therapeutical effect.When pressing " regularly " key, CPU sets different timing parameters according to the number of times by this key, can select three kinds of different timings, presses once " regularly " key, and CPU sets 15 minutes regularly, simultaneously, and to latch J
1Low level is sent in corresponding position, makes timing indicator DTL(or DTR) bright and do not dodge; Press secondary " regularly " key continuously, CPU sets 20 minutes regularly, passes through J simultaneously
1Outfan make timing indicator DTL(or DTR) flash each second once; Continuously by three " regularly " keys, CPU then sets 30 minutes regularly, makes DTL(or DTR simultaneously) flash fast, no matter which kind of is set regularly, when timing then, CPU passes through J again
1The alarm outfan send regularly alarm signal, start BXL(or BXR) play out one section melodious melody, the expression treatment finishes.When button " manually " key, enter the manual work mode, CPU makes charactron be shown as " 00 ", and makes manual display lamp bright, simultaneously by latch J
3Corresponding outfan sends electric pulse one time, after this whenever by a manipulated key, just sends electric pulse stimulation one time, not button no-output then.
Another outstanding characteristics of Computerized medical instrument for respiratory system of the present invention are, keyboard described in this embodiment, charactron, display lamp, potentiometer, on whole built-in computer control boards such as accessory power outlet, only the light-emitting area of button keycap, charactron and display lamp, the adjusting knob of potentiometer and the jack of accessory power outlet are exposed machine shell panel.Fig. 4 has provided the layout of panel, wherein keyboard is made up of 10 buttons, be arranged in the panel centre position, the right and left symmetry, there are four keys (" number of times (+) ", " number of times (-) ", " regularly ", " manually ") on every limit, there are two keys (" resetting ", " spray medicine ") centre, five knobs are arranged in the lower position of button, the left side is two " output L " knobs, the right is two " output R " knobs, middle " dose " knob, the positive side of casing, about two output plughole (see figure 1)s are respectively arranged.Fig. 5 has provided the charactron on the display screen and the installation site of display lamp, also is the right and left symmetry, and there are the double figures sign indicating number pipe of demonstration " inferior/minute ", " regularly " display lamp and " manually " display lamp in every limit.The symmetric design of the right and left of therapeutic instrument of the present invention makes it to treat two patients simultaneously.
Content of the present invention is except that the hardware unit of above-mentioned main frame and soniclizer, also comprise the control sequence that is exclusively used among the EPROM of being solidificated in of the present invention, be characterized in adopting assembler language to write, it cooperates the microcomputer control circuit of main frame inside to realize above-mentioned various functions.Flow chart as shown in Figure 6.
Computerized medical instrument for respiratory system of the present invention has following advantage:
1, the function with existing external diaphragm pacemaker and ultrasonic ultrasonic delay line memory combines together, both can automatically produce electric pulse stimulation, promote the patient respiratory diaphragm pacing, can carry out again the treatment of ultrasonic atomization spray medicine, physical treatment and medicine treatment start at the same time, and result for the treatment of is significantly improved.
2, electric pulse repeats frequency of stimulation, only just can show its numeral with charactron simultaneously in arbitrarily selection in each minute 3-20 time the scope with " number of times (+) " and " number of times (-) " two buttons, and not only easy to operate but also supervision intuitively.
3, utilize " regularly " key and display lamp thereof can realize three kinds of different timing functions, by " regularly " key once, timing indicator is bright and do not dodge, represent 15 minutes regularly, press secondary " regularly " key continuously, the timing indicator per second flashes once, represents 20 minutes regularly; By three " regularly " keys, timing indicator flashes fast continuously, table 30 minute timing.Timing arrives, and main frame promptly broadcasts melody, informs that treatment finishes.This provides the motility of selection treatment time for doctor and patient.
4, adopt advanced Control Technique of Microcomputer and VLSI Design, hardware is simple, dependable performance, compact conformation, good looking appearance, P/C be than high.
5, can treat various respiratory systemic diseases such as bronchitis, asthma, emphysema, lung breast disease effectively, be suitable for applying, market is very widely arranged, can create good social benefit and economic benefit in hospitals at different levels and various medical institutions.
