1. At present, some intelligent oximeters on the market have built-in calibration functions, and the results of measuring finger blood with them can be similar to those of measuring venous blood with biochemical instruments. Some manufacturers' products have quality control solutions and test cards, which are specially used to test the accuracy and normal operation of oximeter. Please pay attention to the inquiry when purchasing.
2, the size and clarity of the display screen, whether the battery is easy to replace, whether the appearance is beautiful, the size must be clear first. At present, the accuracy of home oximeter can't reach the diagnostic standard. However, the measured blood oxygen content should be close to that measured by biochemical instrument, and the difference should not be too big.
3, see the warranty project and other after-sales service, service to understand the warranty period of the oximeter.
4. Look at the brand and price. When choosing an oximeter, we should not only look at the price of the instrument, but also consider the cost of consumables. In addition, the product quality of the selected brand oximeter is guaranteed and the measurement results are more accurate. Which brand of oximeter is good? Bian Xiao recommended ten brands of oximeter. Brand ranking of oximeter >; & gt
The following small series introduces the advantages and disadvantages of portable oximeters (including nail oximeter, palm oximeter, wrist oximeter and health watch oximeter) on the market to help you choose.
A, nail oximeter
Advantages:
1, small size, no cable, easy to carry.
2, simple operation: just one step-finger inserted into the machine, intelligent automatic boot monitoring, finger taken out of the machine, automatic shutdown to save electricity.
3. Rich monitoring functions: blood oxygen saturation, pulse rate, blood perfusion index (reflecting the blood perfusion at the measurement site, the greater the pulsating blood flow, the more pulsating components, and the greater the PI value, the higher the accuracy of measuring blood oxygen saturation).
4. Bluetooth data transmission: Through Bluetooth transmission, synchronous display and mass storage of data on mobile phones can be realized.
5. Shading design: Shading sheet design effectively shields the interference of ambient light on measurement.
6. Energy saving and environmental protection: it has power management function, automatic shutdown without signal for 8 seconds, and battery power management.
7, medical grade products, medical devices registration certificate.
Disadvantages:
1, non-rechargeable: two No.7 dry batteries can be used for continuous measurement for about 30 hours.
2, easy to fall off: the oximeter plus two No.7 batteries are clamped on the fingers, the weight is relatively large, the fingers are more tolerant, and it is easy to fall off when sleeping.
3, the comfort is not high: wearing it for a long time, it is very painful and the comfort is not high.
Second, the palm oximeter
Advantages:
1, medical-grade product with medical device registration certificate.
2. Monitorable parameters: oxygen saturation, pulse rate and blood perfusion index.
Disadvantages:
1, the cable is too long to carry, and it is not wearable.
2, non-rechargeable: use dry batteries.
Third, the wrist oximeter
Advantages:
1, compact design, the main machine is worn on the wrist of the patient, and the blood oxygen probe is worn on the finger, which has low tolerance and high comfort.
2. The product has low power consumption and is equipped with a rechargeable 3.7V lithium battery, which can be used repeatedly.
3. Small size, light weight and easy to carry.
4. When no signal is generated, the product will automatically shut down.
5. Sleep monitoring system, which can display data on PC or mobile phone via Bluetooth.
6, medical grade products, medical devices registration certificate.
Disadvantages: external oxygen probe, choose the appropriate oxygen probe if necessary.
Fourth, the health watch oximeter
Advantages:
1, a health watch integrating blood oxygen, pulse rate, ECG and pedometer, which is easy to carry.
2. Display parameters: oxygen saturation numerical display, pulse rate numerical display, heart rate value and ECG waveform display, pedometer steps and calories display.
3, data storage function, the stored data can be wirelessly uploaded to the mobile terminal.
4, with clock function.
5. Charging function.
6. Reflective blood oxygen is provided on the side, and a probe for monitoring blood oxygen content during sleep is also provided. The measurement is convenient.
Disadvantages: sanitary products, no medical device registration certificate.
In a word, the use of intelligent oximeter has brought great convenience to middle-aged and elderly patients. Of course, patients must go to the hospital regularly for re-examination, combine the results of medical equipment and home oximeter, follow the doctor's guidance, and carry out the most reasonable and effective treatment for their own condition.
