There is the electrode be identified with storage function
Technical field
This utility model relates to sparking electrode circuit, is specifically related to a kind ofly have the electrode be identified with storage function.
Background technology
, there is following technical problem in current armarium sparking electrode: 1, sparking electrode manufacturer is various, and electrode quality is uneven, and whether hospital's None-identified sparking electrode is fake products, and the therapeutic effect of fake products is poor; 2, sparking electrode does not have tally function, after used a period of time, uses up when the service life of sparking electrode, and user of service does not know this situation, think it is medical equipment failure or sparking electrode fault, and keep in repair, waste maintenance time and maintenance cost.
Summary of the invention
In order to solve above-mentioned technical problem, this utility model provides a kind of electrode with identification and storage function, electrode model and numbering is write in advance according to the feature of electrode itself and electrode factory testing situation, simultaneously according to the different styles of each electrode, it is electrode setting service life, in use, first electrode is identified, judge whether electrode is standard compliant electrode model and numbering, if can identify this electrode, equipment normally can enter duty; Simultaneously in the process of electric discharge, the number of times that electrode uses is counted, the residual life of real-time detecting electrode.
The scheme that this utility model solves the problems of the technologies described above is as follows:
There is the electrode be identified with storage function, comprise electrode contact, electrode hood, electrode wires and storage chip, described electrode contact has 4 pins, the wherein inner connection electrode line of 2 pins, the inner of other 2 pins connects storage chip, the outer end of 4 pins connects external circuit, and electrode hood covers the inner of storage chip and 4 pins.
Described external circuit comprises CPU and clamp circuit, and storage chip connects clamp circuit, and clamp circuit connects the I/O interface of CPU.
Described clamp circuit comprises pull-up resistor R38, current-limiting resistance R37, Zener diode D2 and Zener diode D3, power Vcc connects the negative pole of Zener diode D2, the negative pole of Zener diode D3 connects the positive pole of Zener diode D2, the plus earth GND of Zener diode D3, the I/O interface of CPU is connected between two Zener diodes, pull-up resistor R38 is connected between the pin 1 of power Vcc and storage chip, current-limiting resistance R37 one end is connected between two Zener diodes, the current-limiting resistance R37 other end is connected to the pin 1 of storage chip, the pin 2 ground connection GND of storage chip.
Described storage chip model is DS2431/DS2432.
This utility model has following advantage relative to prior art:
This sparking electrode, add a storage chip at the inner pin of electrode contact, this storage chip is write in advance to the model number of electrode, and according to the electrode of different model, set different service life, the service life of electrode sets by according to clinical experience herein.When electrode insertion armarium uses, storage chip and armarium master control borad transmission of signal, the CPU in master board comprises an I/O port and reads and writes storage chip, and clock signal is produced by CPU, carries out signal exchange by 1-wire bus protocol.CPU reads the related data in storage chip, first identifies the model of electrode, numbering, judges the electrode having record whether this electrode belongs to qualified, belong to have and record qualified electrode, armarium can work by normal boot-strap normal operation, if defective, reminds user to change other electrode; Normally work at armarium, in use, CPU counts the number of times that electrode uses sparking electrode, when the number of times used reaches the service life of this electrode, makes prompting, reminds user to discard this electrode.This sparking electrode, ensures that user uses intra-company to be up to the standards numbered electrode, and the number of times simultaneously used electrode carries out storage memory, carries out waste treatment, avoid carrying out unnecessary maintenance time prompting user electrode reaches service life.
