Abstract
The utility model relates to a random pulse device for an electric needle instrument, which is characterized in that openings P1.7-P1.0 of an SCM IC are respectively connected through diodes with one end of each of switches K1-K8 which are used for input selection, and the other end of each of the switches K1-K8 is connected with an opening P3.0 of the SCM IC together; an opening P3.2 of the SCM IC is connected with the input end of a power amplifier through a photoelectric coupler, and the output end of the power amplifier is connected with the primary side of a step-up transformer. The utility model can generate random pulse output to avoid a human body to generate physiological adaptation, and has a better curative effect compared with a fixed frequency pulse.
Description
This utility model relates to the pulser on a kind of acupuncture and moxibustion instrument.
In the prior art, electric acupuncture apparatus be at the acupuncture pinprick after on the acupuncture point, by electric acupuncture apparatus to its input pulse, the pulse that is produced is the pulse of fixed frequency, along with the lasting stimulation of same frequency, body obviously descends to the susceptibility that stimulates, and this is referred to as to adapt on the physiology.The pulser that regulating frequency is also arranged generally realizes that with the resistance of regulating in the RC circuit error is bigger, and it is very difficult to reproduce frequency exactly.
The purpose of this utility model is to provide a kind of device that produces random pulses.
The technical solution of the utility model is: mouth P1.7～P1.0 of single-chip microcomputer IC is connected to the end of the K switch 1～K8 that is used to import selection respectively by diode, the other end of K switch 1～K8 is connected on the mouth P3.0 of single-chip microcomputer IC altogether, the mouth P3.2 of single-chip microcomputer IC is connected on the input of power amplifier by photoelectrical coupler, and the outfan of power amplifier is connected on the former limit of booster transformer B.K1～K8 is the binary coded decimal toggle switch, be used for selected pulse frequency within a certain period of time, single-chip microcomputer IC makes P3.0 become " 0 " by " 1 " by output order, reuse reads in instruction and reads in the data of mouthful P1.0～P1.7, the pulse of sending different frequency according to the setting value per os P3.2 of K1～K8 by the program in the single-chip microcomputer IC.Here the certain frequency pulse of indication refers to send within a certain period of time the pulse at several irregular intervals, regulates the impulse density of K1～K8 scalable output pulse at a time Inner.
This utility model compared with prior art has following advantage:
(1). by regulating plucking number sign switch K1～K8, can determine the output impulse density in the unit interval, its favorable reproducibility is beneficial to patient's repetitive therapy repeatedly after choosing the optimum pulse frequency.
(2). pulse is realized by the software in the single-chip microcomputer, can produce the pulse output of frequency accidental, and its mobility scale our experiments show that about 10%, is eager to excel for the impulse stimulation of the more same frequency of stimulation at acupuncture point, has curative effect preferably.
The utility model will be further described below in conjunction with drawings and Examples:
Accompanying drawing is circuit theory diagrams of the present utility model;
Embodiment: referring to accompanying drawing, it is 8051 or 8751 chip that single-chip microcomputer IC can select model for use, mouth P1.7～P1.0 of single-chip microcomputer IC is connected to the end of the K switch 1～K8 that is used to import selection respectively by diode, the other end of K switch 1～K8 is connected on the mouth P3.0 of single-chip microcomputer IC altogether, the mouth P3.2 of single-chip microcomputer IC is connected on the input of power amplifier by photoelectrical coupler, and the outfan of power amplifier is connected on the former limit of booster transformer B.Mouth P1.5～P1.7 of described single-chip microcomputer IC is connected on K switch 11～K9 one end of time input selection by diode respectively, and the other end of K switch 11～K9 is connected on the mouth P3.1 of single-chip microcomputer IC altogether.The mouth P1.2 of described single-chip microcomputer IC is connected on continuously/at random by diode on the end of selector switch K12, and the other end of K switch 12 is connected on the mouth P3.1 of single-chip microcomputer IC.Cross-over connection has the switching regulator adjustable resistance on the secondary of transformator B, and the switch one of described adjustable resistance terminates at the mouth P3.2 of single-chip microcomputer IC, and the other end is connected on the mouth P3.1 of single-chip microcomputer IC.Pulse signal is exported through P3.2, and photoelectrical coupler GD is used for back level signal and prime is isolated, and prevents that noise signal from entering in the circuit.Audion T1 is used for paraphase, be connected to ten tunnel output signals (one road signal has only drawn in the accompanying drawing) on its colelctor electrode, whenever carry out power amplification by an audion T2 on the way, the output termination after the amplification is boosted and is become the former limit of device B, and secondary can be used as pulse signal output behind adjustable resistance.The XTAL1 of single-chip microcomputer, XTAL2 two pins span are connected to crystal oscillator, and the RES pin connects power end by switch.K9, K10, K11 are provided with switch in the burst length, and behind P3.1 pin output " 0 " level, through port P1.7～P1.5 reads the on off state of K9, K10, K11 can be by the burst length of software control P3.2 output.K12 is used to select to export consecutive pulses or pulse at random.And K13～K22 is the switch of the switching regulator adjustable resistance of No. ten transformator secondary, have only when the switch of all adjustable resistances (potentiometer) all disconnects, be P3.1 output " 0 " level, the data of being read in by the P1.0 mouth are during for " 1 ", and single-chip microcomputer is just through P3.2 output pulse.
