With the release of the national "new ten" epidemic prevention policy on December 7, the era of dynamic zero clearing has passed. With the full liberalization of epidemic prevention in all regions, the proportion of COVID-19 positive people in all regions has reached a peak. Most of them can safely pass through the process of infection and natural immunity, but for a small number of people with underlying diseases or low immunity, there is a possibility of transitioning to severe illness.

Some doctors suggest that vulnerable populations should receive antiviral medication treatment as early as possible in the early stages of the disease, and prepare finger clip oximeters for severe monitoring. In order to ensure the safety of the elderly at home, many families have started to purchase household blood oxygen meters. For a time, the supply of blood oxygen meters was tight, becoming another out of stock epidemic prevention product after antigen detection reagents, lotus plague clearance, and ibuprofen.

Wuhan Xinyuan Semiconductor, as an excellent semiconductor design manufacturer in China, can provide a complete solution for portable finger clip oximeters based on CW32F003E4P7, achieving a weak perfusion detection capability of 0.2%.

CW32F003E4P7 Blood Oximeter Scheme Features:

1. Low weak perfusion performance, with a minimum of 0.2%. (Accurate measurement can be ensured in patients with weak signals, children, high blood loss, and cold limbs with low perfusion)

2. Automatic adjustment of light intensity. (The emission light intensity can be automatically adjusted according to the size of the patient's finger, ensuring better signal quality and lower power consumption. Different sizes of fingers and skin colors can be used)

3. Excellent ambient light cancellation function. (Can be used indoors and in clinical environments with strong lighting)

4. TFT display, using 0.96 inch TFT color screen display

5. Measurable blood sample saturation SpO2, pulse rate PR, and perfusion index PI

6. Screen orientation can be flipped.

7. Quickly generate measurement results in 5s

8. Blood oxygen saturation and pulse rate exceeding limit alarm

9. Fingerless Auto Key

10. Battery level alarm and automatic shutdown when battery level is low

Technical specifications of CW32 oximeter solution:

The portable finger clip oximeter is compact, convenient to carry, and easy to use. Generally, the elderly can operate it quickly on their own. The finger clip oximeter no longer requires blood to be taken for blood oxygen measurement. With a gentle clip on your finger, you can easily check your blood oxygen, pulse, and other indicators. You can check your health anytime and anywhere at home, providing convenience for the general public.

Unlike similar solutions on the market, CW32F003E4P7 is a cost-effective 32-bit MCU with a built-in FLASH capacity of only 20KByte. While the chip cost is effectively controlled, the high-precision simulation function integrated with MCU still supports excellent blood oxygen detection capabilities, ensuring accurate measurement in patients with low perfusion such as weak signals, children, high blood loss, and cold limbs.

The key advantages of CW32F003 in the application of finger clip oximeter are:

1. 12 bit SAR ADC can achieve ENOB 11.3 bits

2. Built-in voltage reference

3. Wide voltage operating range 1.65V~5.5V

4. High performance and low cost

In the application of blood oxygen meter solutions, Wuhan Xinyuan Semiconductor provides rich and complete information such as user manuals, design documents, and supporting SDKs for the CW32F003 microcontroller, helping customer engineers quickly get started and have more energy to invest in the systematic implementation of terminal products, creating more competitive products in the market.
