CMS50QB Pediatric and Infant Pulse Oximeter with Colour Display
The CONTEC CMS50QB is a fingertip pulse oximeter specially designed for measuring peripheral oxygen saturation (SpO₂) and pulse rate in children and infants. The measuring chamber is adapted to smaller fingers, allowing the clip to fit securely and provide effective shielding from ambient light, which is an important prerequisite for accurate pulse oximetry measurements.
The device is also suitable for adults with small hands and thin fingers where a standard adult-sized fingertip clip does not provide an adequate fit.
The CMS50QB uses photoelectric oxyhaemoglobin measurement technology with pulse waveform analysis. Its dual-colour OLED display simultaneously shows the numerical SpO₂ and pulse rate values, pulse waveform and pulse bar.
The child-friendly design is complemented by an animal-pattern neck strap and blue or pink colour options, which can help reduce anxiety associated with examinations. The device is powered by a rechargeable button battery, eliminating the need for regular battery replacement.

Product Information
Product name: CMS50QB Pediatric and Infant Pulse Oximeter with Colour Display
Manufacturer: CONTEC Medical Systems Co., Ltd.
Model / type: CMS50QB
Product category: Fingertip pulse oximeter for children and infants
Measured parameters: Oxygen saturation (SpO₂), pulse rate (PR), pulse waveform, pulse bar
Display: Dual-colour OLED display with 4 display modes and inverted view
Power supply: Rechargeable button battery with USB charging unit
Device dimensions: 46 × 40 × 29 mm
Colour options: Blue and pink
Wireless communication: According to distributor information, version without Bluetooth connectivity
Target group: Children and infants, as well as adults with small hands and thin fingers
Applications: Home patient monitoring, primary care, paediatric care, inpatient care and patient transport
Measurement Ranges and Accuracy
SpO₂ measurement range: 0–100%
SpO₂ resolution: 1%
SpO₂ accuracy: ±2% in the 70–100% range; the manufacturer does not specify accuracy below 70%
Pulse rate measurement range: 30–250 bpm
Pulse rate resolution: 1 bpm
Pulse rate accuracy: ±2 bpm or ±2%, whichever is greater
Low-perfusion performance: Measurements can be evaluated down to a pulse modulation of 0.4%; under these conditions, SpO₂ accuracy is ±4%, while pulse rate accuracy is ±2 bpm or ±2%
Ambient light resistance: The difference between measurements taken under artificial or indoor natural light and measurements taken in a dark chamber is less than ±1%
Display and Operation
Display type: High-contrast dual-colour OLED display, clearly readable even in dark environments
Display modes: 4 layouts, including an inverted ("upside down") view
Displayed information: SpO₂ value, pulse rate, blue pulse waveform and pulse bar
Operation: Single-button control
Low battery indicator: Dedicated icon indicates a low battery level
Automatic shutdown: If no finger is detected in the measuring chamber, the device switches off automatically after approximately 5 seconds
Power Supply and Operation
Power source: Rechargeable button battery, included
Charging: Using the supplied charging unit and USB cable, via a computer/laptop or the supplied USB power adapter
Operating voltage: 3.6–4.2 V DC
Current consumption: Less than 80 mA
Battery cycle life: At least 300 charge/discharge cycles
Operating Principle and Classification
Measurement principle: Photoelectric oxyhaemoglobin measurement technology with pulse waveform analysis
Applied part classification: Internally powered device with Type BF applied part
Dimensions and Package Contents
Dimensions
Device length: 46 mm
Device width: 40 mm
Device height: 29 mm
Neck strap: Included, with quick-release buckle
Package Contents
1 × CONTEC CMS50QB pediatric and infant pulse oximeter
1 × Rechargeable button battery
1 × Battery charging unit
1 × USB cable
1 × USB power adapter (DC)
1 × Animal-pattern neck strap with quick-release buckle
1 × User manual
Recommended Use and Applications
Reliable oxygen saturation measurements in children require the sensor to fit securely around the finger without gaps that allow ambient light to enter. The child should also remain still during the measurement.
The CMS50QB supports these requirements through its smaller measuring chamber, which provides a stable fit on small fingers. Its child-friendly design can also help create a calmer measurement environment.
Typical applications include:
Home monitoring of children receiving temporary or long-term oxygen therapy
Home monitoring of lower respiratory tract infections, including bronchiolitis and pneumonia, according to medical advice
Monitoring children with asthma during periods of worsening symptoms and assessment of treatment response
Regular monitoring of children with congenital heart disease according to the protocol established by the treating physician
Quick screening and orientation measurements in paediatric and general practitioner practices
School health services and primary healthcare settings
Paediatric outpatient clinics and emergency triage
As a supplementary device in inpatient departments
Ambulance services and patient transport
Measurement in adults with small hands and thin fingers where a standard adult fingertip clip does not fit properly
Key Benefits
Child-sized measuring chamber: Designed for smaller finger diameters, providing a secure fit and supporting stable signals and reliable SpO₂ readings
OLED display readable in the dark: Suitable for nighttime monitoring and use in dimly lit hospital rooms or children's bedrooms without additional lighting
Four display modes: The inverted view allows readings to be easily viewed from the perspective of a parent or healthcare professional while the device remains on the child's finger
Rechargeable battery: USB charging eliminates the need for regular battery replacement and supports economical long-term use
Child-friendly design: The animal-pattern neck strap and blue or pink colour options can help reduce anxiety associated with examinations
Portable: The device can be detached from the neck strap using the quick-release buckle, making it convenient for travel and outdoor activities
Energy-efficient operation: Automatic shutdown when no finger is detected helps prevent unnecessary battery drain
Professional Information for Accurate Measurements
Measurements should be performed while the patient is at rest. Use during movement or physical activity is not recommended
Strong ambient light, nail polish, artificial nails, cold fingers and poor peripheral perfusion may affect the measurement results
In cases of centralisation, particularly low perfusion, severe anaemia, carboxyhaemoglobinaemia or methaemoglobinaemia, pulse oximetry readings should be interpreted with caution
According to published literature, pulse oximetry may overestimate true arterial oxygen saturation in individuals with darker skin pigmentation; this should be considered during clinical assessment
The manufacturer does not specify accuracy for displayed values below 70%. A reading in this range requires immediate medical attention
The device is intended for orientation and monitoring measurements and does not replace medical examination, diagnosis or therapeutic decision-making
