2. Informació de seguretat
Important: This device is intended for non-medical use and is not a substitute for professional medical advice or diagnosis. Consult your physician for any medical concerns.
- No utilitzeu l'oxímetre en un entorn de ressonància magnètica o TC.
- No utilitzeu l'oxímetre en situacions que requereixin una monitorització contínua.
- Keep the device away from children. Small parts may be a choking hazard.
- Do not use the oximeter on the same arm as a blood pressure cuff or arterial catheter.
- Avoid placing the oximeter on fingers with nail polish, artificial nails, or excessive dirt, as this may affect accuracy.
- Assegureu-vos que el dit estigui net i sec abans d'utilitzar-lo.
3. Producte acabatview
3.1. Característiques clau
- Low power consumption, simple to operate, light, and portable.
- Oxygen saturation (SpO2) and Pulse Rate (PR) display.
- Automatic power-off in 8 seconds when no finger is detected.
- Pulse strength indicator.
- Strong anti-interference capability.
3.2. Modes de visualització
The device features an OLED display. It shows:
- Oxygen Saturation (SpO2) percentage.
- Pulse Rate (BPM).
- Pulse bar graph.
4. Configuració
4.1. Instal·lació de la bateria
- Obriu la tapa del compartiment de la bateria a la part posterior del dispositiu.
- Insert two (2) AAA 1.5V alkaline batteries, ensuring correct polarity (+ and -).
- Tanqueu bé la tapa del compartiment de la bateria.
El dispositiu funciona dins d'un voltagrang de 2.6V a 3.6V.
5. Instruccions de funcionament
- Ensure the oximeter has batteries installed.
- Obriu el clamp of the oximeter.
- Insert one finger into the rubber opening of the oximeter, ensuring the finger is placed correctly and comfortably.
- Allibera el clamp. The oximeter will automatically turn on and begin measurement.
- Keep your hand still during the measurement. Movement can affect accuracy.
- Read the SpO2 and Pulse Rate values displayed on the OLED screen.
- After removing your finger, the device will automatically power off after approximately 8 seconds.
5.1. Measurement Accuracy Considerations
- Saturació d'oxigen: Accuracy is ±2% for readings between 70% and 99%. For readings below 70%, accuracy is not defined.
- Freqüència de pols: Accuracy is ±1% or ±1 BPM, whichever is greater.
- Weak Perfusion: The oximeter can accurately display oxygen saturation and pulse rate even with a pulse filling degree as low as 0.6%.
- Light Interference: Compared to measurements in a dark room, the deviation in oxygen saturation under natural light and illuminated conditions is less than ±1%.
6. Manteniment
6.1. Neteja
- Netegeu la superfície de l'oxímetre amb un drap suauampened with medical alcohol (75% ethanol) or isopropyl alcohol.
- Do not immerse the device in water or any cleaning solution.
- Assegureu-vos que el dispositiu estigui completament sec abans de reutilitzar-lo.
6.2. Emmagatzematge
- Guardeu l'oxímetre en un lloc fresc i sec, allunyat de la llum solar directa i de temperatures extremes.
- Traieu les piles si no heu d'utilitzar el dispositiu durant un període prolongat per evitar fuites.
7. Solució De Problemes
| Problema | Causa possible | Solució |
|---|---|---|
| Sense pantalla després de l’encesa | Les bateries estan esgotades o instal·lades incorrectament. | Canvieu les piles o torneu-les a instal·lar amb la polaritat correcta. |
| Lectures inexactes | Finger not inserted properly; excessive movement; nail polish; cold finger. | Re-insert finger correctly; remain still; remove nail polish; warm finger. |
| Missatge d'error "Dit fora" o similar | Dit no detectat o mal col·locat. | Ensure finger is fully inserted into the sensor. |
