NEW ECG Simulator ECG Signal Generator Waveform Simulator SKX2000C+
Description
SKX-2000+ series ECG signal simulator is a signal simulation tool developed by Xuzhou Mingsheng Company for the development and detection of ECG products. Because it can generate a variety of human ECG signals, it is a development heart. An essential tool for electrical products, with a wide range of signal amplitudes, can simulate a variety of amplitude and frequency of ECG signals, is an important tool for the development of ECG products. The simulator also has the detection function of the electrocardiogram products, which is used to detect whether the various parameter indexes of the electrocardiograph products can reach the national standard requirements, and the subsequent chapters will detail the setting of various signals in the detection process.
The SKX-2000+ features are as follows:
1. It adopts 10 universal ECG connectors, which can easily and quickly connect the lead wires of ECG products such as monitors and electrocardiographs.
2, built-in 18650 large capacity lithium battery, power management module, in the course of use to ensure stable power supply, low interference output. Optional standard micro usb universal interface power charger.
3, using menu-style operation, parameter changes are simple, convenient, fast, convenient for user settings.
4. Use OLED display to display menu contents.
5, simple button operation, menu management, easy to use,
6, built-in Chinese and English waveform settings instructions, easy to understand the waveform settings and parameter selection.
SKX-2000+ connection to ECG equipment:
1, ECG machine connection: RA-R (right hand), LA-L (left hand), LL-F (left leg), RL-RF (N) (right leg), C1 - C6 (V1-V6) chest lead ;
2, monitor connection: RA - right hand (white), LA - left hand (black), LL - left foot (red), RL - right foot (green), C1 - C6 chest lead (brown);
3. Three-lead connection method: RA-right hand (white), LA-left hand (black), LL-left foot (red);
Or when the lead is collected as II;
RA-right hand (white), LL-left foot (red), RL- (reference ground, feedback point);
Or when the collection lead is I;
RA-right hand (white), LA-left hand (black), RL- (reference ground, feedback point);
4. Two-lead connection method: connect RA-LL when the lead is II, and connect RA-LA when the lead is I.
5, the European standard corresponding connection method: L-LA R-RA RF (N)-RL F-LL C1-C6 (V1-V6);
Note for SKX-2000+:
1. The SKX-2000+ series ECG simulator can calibrate the ECG equipment. The calibration lead is limited to II, that is, the signal amplitude of the RA-LL output, and the RA lead of the ECG device is connected to the simulator. The RA end, LL lead to the LL end of the simulator, the signal collected by the ECG device satisfies the signal amplitude range set in the software 0.1mV-4mV;
2. The amplitude of the waveform in the ECG waveform is a fixed amplitude and cannot be changed in amplitude;
3. If you are calibrating other leads, please follow the instructions below:
A, I lead calibration: connect the lead line RA to the analog RA end, the lead line LA is connected to the analog LA end, at this time the signal collected by the ECG device is the I lead calibration signal;
B, C lead calibration: RA, LA, LL should be connected in parallel to the RA end of the simulator, C1 or other chest lead is connected to the LL end of the simulator, and the C1 (or other chest lead) collected at this time Then it is a standard calibration signal;
4. For the detection method of the bias voltage, when testing the forward bias, please select the sinusoidal waveform, and connect the RA of the ECG device to the LL end of the simulator, and the LL of the ECG device to the RA end of the simulator is positive. Bias voltage test; when testing the negative bias voltage, please select the sinusoidal waveform, and connect the RA of the ECG device to the RA end of the simulator, and the LL end of the ECG device to the LL end of the simulator for the negative bias voltage test;
5. When there is no button operation for one minute, the screen will automatically turn off. After pressing any button, the screen will resume display. After the screen is turned off, the indicator light starts to work, blinking every 5 seconds; after the screen is restored, the indicator light Stop flashing;
Standby working time of SKX-2000+ simulator
1. When the power is displayed as 0%, the simulator can automatically shut down after 1 minute of operation. If any button is selected, the timer will be turned off for delay, and will automatically shut down after no button processing within 1 minute.
2. When the power is displayed as 10%, the simulator can automatically shut down after 5 minutes of operation. If any button is selected, the timer will be turned off for delay, and will automatically shut down after no button processing within 5 minutes.
3. When the power is lower than 0%, the simulator will not be turned on again;
Software interface description:
first row:
The current waveform is represented as the label of the waveform type generated by the current simulator. 98% Battery indicator percentage
Second line: ECG waveform
Indicates that the waveform type of the current simulator is an electrocardiogram waveform.
Third line: project General ECG
Indicates the items included in the waveform produced by the current simulator. The details are described in the following waveform type introduction.
Fourth line: parameter 60 bpm
Indicates the specific parameters of the waveform generated by the current simulator. This parameter is the content of the corresponding waveform item.
* The symbol is the current cursor indication, which means that the current operation is in different menu layers; when the third layer menu is used, the * symbol has special meaning, which means that the increase and decrease keys can be moved left and right in the parameter value. When the confirmation key is selected, * will be displayed as? , means that you can directly change the hundred, ten, and one digits in the parameter value; select the confirmation button again? Will change to the * symbol.
Key Description:
The simulator has four buttons
From left to right, the return key, increase (right shift) key, decrease (left shift) key, and confirm key.
The simulator uses the OLED screen to display content. The software interface has three layers of menus, which are:
The first layer of the menu The waveform type of the current waveform is displayed on the second line of the screen, such as the ECG waveform;
The second layer of the menu, the current project content in the current waveform, such as ordinary ECG;
Menu layer 3 parameters, specific parameters of the current waveform, such as 60 bpm;
Button definition:
