Advantages:
1. The product is small in size, no cable, easy to carry
2. Easy to operate: just one step - finger inserted into the machine, intelligent automatic power-on monitoring, finger out of the machine, automatic power-off power saving.
3. Rich monitoring functions: oxygen saturation, pulse rate, perfusion index (reflecting the perfusion of the measurement site, the greater the pulsating blood flow, the more pulsatile component, the greater the PI value, the higher the accuracy of the measurement of oxygen saturation).
4. Bluetooth Data Transmission: Synchronized data display and mass storage on cell phone through Bluetooth transmission.
5. Shade design: Shade design, effectively shield the interference of ambient light on the measurement.
6. Energy saving and environmental protection: with power management function, 8 seconds no signal automatic shutdown, and battery power management.
7. Medical grade product with medical device registration certificate.
Disadvantages:
1. Non-rechargeable: two 7 dry batteries are used, two dry batteries can be used for continuous measurement for about 30 hours,.
2. Easy to fall off: oximeter plus two 7 batteries clamped on the finger, the weight is relatively large, the finger to withstand a lot of force, sleep monitoring is easy to fall off.
3. Comfort is not high: long time wearing, the clip on the finger, it hurts, comfort is not high.
2. Palm oximeter
Advantages:
1. Medical grade products, with medical device registration certificate.
2. Parameters can be monitored: oxygen saturation, pulse rate, perfusion index.
Disadvantages:
1.Cable is too long, not convenient to carry, non-wearable device.
2. Non-rechargeable: dry battery is used.
Three, wrist oximeter
Advantages:
1. Compact design, the host is worn on the patient's wrist, the oxygen probe is worn on the fingers, the fingers bear little strength, high comfort.
2. Low power consumption, equipped with rechargeable 3.7V lithium battery, can be recharged and used.
3. Small size, light weight, easy to carry.
4. When no signal is generated, the product will automatically shut down.
5. Sleep monitoring system, data can be displayed on PC or cell phone via Bluetooth.
6. Medical grade product with medical device registration certificate.
Disadvantages:
External oximetry probe, if you need to choose the right oximetry probe.
Four, health watch type oximeter
Pros:
1. A set of blood oxygen, pulse rate, ECG, pedometer in one health watch, easy to carry.
2. Display parameters: blood oxygen saturation value display, pulse rate value display, heart rate value and ECG waveform display, pedometer steps, calories display.
3. Data storage function, stored data can be wirelessly uploaded to mobile terminal.
4. With clock function.
5. Rechargeable function.
6. Reflective oximetry is provided on the side, and a probe for sleep monitoring of blood oxygen level is also provided. Easy to measure.
Disadvantages:
Health grade product, no medical device registration certificate.
So I would opt to buy a wrist oximeter or a health watch.
