Due to the use of electron tubes in the structure of these electrotherapy instruments, they are large in size and consume a lot of power. The choice of physiotherapy equipment for different patients depends entirely on the experience of clinicians. Some electrotherapy instruments such as: K89-II computer intermediate frequency electrotherapy instrument although It is controlled by 8-bit single-chip microcomputer, and there is also an instrument panel. The prescription is also solidified in a dedicated integrated chip. The wave band is mainly intermediate frequency, and there are several fixed waveforms.

[0028] specific implementation
[0029] The specific implementation of "a kind of intelligent full-band electrotherapy instrument for general practitioners" of the present invention will be described in detail below in conjunction with the accompanying drawings:
[0030] 1. Selection of chip and its application circuit
[0031] 1) ADSP5 and ADSP9. In order to reduce the complexity of the hardware and software structure of the electrotherapy instrument of the present invention, ADSP5 and ADSP9 are selected as one of the same chip ADSP21XX series chips, and the specific technical parameters take ADSP2181 as an example. Like other DSP chips of ADI, the ADSP2181 is also based on the Harvard structure, that is, a parallel structure based on a separate parallel bus. This structure uses a separate instruction bus and data bus, so that fetching instructions and fetching data and one arithmetic operation Logical operations can be performed simultaneously, so it can perform a multiply...

Abstract
The invention discloses an intelligent full-band electrotherapy instrument for general practitioners, which consists of an output and measurement circuit 1, a total of 5 medical bands and 11 medical frequencies, a power amplifier circuit 2, a phase-locked loop 3, frequency mixing and frequency conversion 4. ADSP5, 27MHz, 40.68MHz, 50MHz shortwave and ultrashortwave single-chip integrated signal generation circuit 6, 433.92MHz, 900MHz microwave section single-chip integrated signal generation circuit 7, 2450MHz microwave section single-chip integrated signal generation circuit 8, ADSP9, data acquisition Card 10, device driver 11, panel program 12, application program 13, virtual instrument development platform 14, portable PC 15, electronic medical record 16, electrotherapy file 17. The structure of the instrument is the combination of PCMCIA bus and portable PC, and the PC can automatically generate electronic medical records and enter the patient's health files. The general practitioner expert-assisted electrotherapy system can help them make a fast and accurate diagnosis, so as to correctly and effectively choose electrotherapy. band. The invention is simple in structure, practical, easy to carry, and is suitable for the occupational characteristic requirements of general practitioners.
Description
technical field [0001] General practitioners are generally generalists who deal with common diseases, frequently-occurring diseases and general emergencies in the form of outpatient services; another characteristic of the work of community general practitioners is door-to-door service. General practitioners often come to handle family patients in the form of home visits. Different situations establish their own family beds and their own medical files. [0002] The invention relates to an electrotherapy instrument for general practitioners, which is designed and invented according to the professional work characteristics of general practitioners and combined with modern electronic technology. Background technique [0003] The methods of converting electrical energy into various therapeutic energies are collectively referred to as electrotherapy. According to the frequency of the current used, it can be divided into low frequency therapy, medium frequency therapy and high fre...
