Dwd-2401 home ecg
1. Ordinary people can understand ecg by "home ecg".
Home ecg is a new type of heart health care instrument. It display digitally five type of the most important ecg parameters. So ordinary people without professional background can understand easily.
2. You can check your heart anytime and anywhere you wanted.
"home ecg" is suitable for people to monitor heart outside hospital, at home, office etc. It has the following features: small size, convenient use, not confined to places and time, long monitoring time, alarm when the parameter beyond the preset threshold. It is the ideal health care instrument for patients of coronary heart disease, arrhythmia and high blood pressure. For sub health people, it is a good method to evaluate heart status.
3. Provide for you a heart insurance.
Using "home ecg", you can monitor heart in real time. It helps prevent heart disease from happening and is also a good guidance for exercise. User may know his heart status by observing the data displayed on the lcd, especially on some special time such as eating, sleeping, toilet, running etc. It is also a reference to evaluate the medicine effect.
Five types of ecg parameter are displayed:
Heart rate:
Normal: 60~100 beats per minute,
Tachycardia: more than 100 beats per minute;
Bradycardia: less than 60 beats per minute.
St segment:
"elevation" and "depression" indicate heart ischmia. Normal range is " 0. 1~ 0. 2".
Qrs amplitude:
High blood pressure patient with "high" qrs amplitude indicate myocardial hypertrophy.
Arrhythmia:
Check "ventricular premature beat" and "atrial premature beat" and alarm each time when such event happened.
Pacemaker signal:
For patient with pacemaker, it can check the pacemaker signal and make a judgment if the pacemaker work well.
Dwd-2704:fingertip pulse oximeter
Features
The device can accurately measure spo2 and pulse rate in a 2% tolerance.
The device will power off automatically without the signal for 4 seconds.
Two aaa size batteries are required for operating, and the continuous working time is 12 hours.
When low-voltage warning is shown on screen and the malfunction may be caused.
The device is so light that its weight with batteries is about 50g.

Dwd-2701: fingertip pulse oximeter
Technical specification
Display format: led
Spo2: 3599% in 2-digit 7-segment digital
Pulse rate: 30240 bpm in 3-digit 7-digital
Pulse wave: 6-segment bargraph
Bettery voltage low indication: led signals
Power requirements: 2aaa size 1.5v alkline battery
Power consumption: less than 40ma
Resolution: +-1% for spo2 and +-1 bpm for pulse rate
Measurement accuracy: +-2% in stage of 70%-99% spo2 and meaningless when stage being smaller than 70%, +-2% bpm for pulse rate
Measurement performance in weak filling condition: oxyhemoglobin and pulse rate can be shown correctly when pulse-filling ratio is 0.5%
Interference resistance capacity against ambient light: deviation is smaller than +-1% between value of oxyhemoglobin measured in natural lighting indoor condition and present lighting sources and that measured in dark room
It is equipped with a function switch, through which the oximeter can be automatically powered off when no finger is in the oximeter more than 8 seconds
