ELECTROCARDIOGRAPH 3 CHANNELS new device, never used
With high resolution thermal array printing system(8 dots/mm), it needs no adjustment, and the record frequency is up to 150Hz. Real-time and continuously record clear and exact 3 channels ECG waveforms and remarks. The remarks include lead sign, sensitivity, paper speed and filter state,etc. In auto mode, one button operation to complete record, which will improve work efficiency. Full touch keyboard and touch screen control make operations more convenient, LCD displays work state and the device status is clear and easily read . Safety classification:Class I, Type CF defibrillator proof applied part. The device can be powered either by AC or DC, with built-in lithium rechargeable battery. This device can record 150 pieces of ECG and print 90 minutes continually in the best DC state. This device can store more than 1000 cases, more convenient for data review and statistic for doctors. The figure of whole device is elegant and gliding. The degree of protection against entry liquids:IPX0, common equipment. According to the degree of safety of application in the presence of a flammable anaesthetic mixture with air or oxygen or nitrous oxide: Equipment not suitable for use in the presence of the gas mentioned above. The device adopts digital signal processor, through AC, DFT and EMG filters to obtain electrocardiogram of high quality. The device has such functions as measuring, analysing and diagnosing conventional ECG parameters automatically to reduce doctor’s burden and improve work efficiency. According to the mode of operation: continuous operation TECHNICAL SPECIFICATIONS 1.1 Environment conditions Operation: a) Environment temperature: +5℃~+35℃ b) Relative humidity: ≤80% c) Power supply: AC:100-240V,50/60Hz DC:7.4V, 3700 mAh rechargeable lithium battery d) Atmospheric pressure: 860 hPa~1060 hPa Transportation and Storage: a) Environment temperature: -40℃~55℃ b) Relative humidity: ≤95% c) Atmospheric pressure: 500 hPa~1060 hPa 1.2 Input way: Floating and defibrillation protection 1.3 Lead: Standard 12 leads 1.4 Patient leak current: <10µA 1.5 Input impedance: ≥50MΩ 1.6 Frequency response: 0.05Hz~150Hz 1.7 Time constant: Time constant>3.2s 1.8 CMRR: >60dB, >100dB(With AC filter) 1.9 EMG interference filter: 25Hz/35Hz(-3dB) 1.10 Recording way: Thermal array printing system 1.11 Specification of recording paper: 80mm(W)*20m(L) high-speed thermal paper 1.12 Paper speed: Auto record: 25mm/s, 50mm/s, error:±5% Rhythm record: 25mm/s, 50mm/s, error:±5% Manual record:5mm/s, 6.25mm/s,10mm/s, 12.5mm/s, 25mm/s, 50mm/s, error:±5%. 1.13 Sensitivity selections: 2.5,5,10,20,40mm/mV, 5 options ,error:±5%.
