Dr. Odin OLS103 Mercury-Free LCD Sphygmomanometer

The Dr. Odin OLS103 LCD Sphygmomanometer is a mercury-free manual blood pressure monitoring device designed for clinical and home-care use. It combines a manual inflation system with a clear LCD display, allowing users to observe blood pressure readings through both the LCD column and numerical display.

Unlike a fully automatic digital BP monitor, the OLS103 uses manual cuff inflation and stethoscopy-based measurement. Its cotton cuff with D-ring closure is designed for secure positioning around the arm, while the LCD display provides a clear way to observe pressure readings.

The mercury-free design eliminates the need for mercury-based pressure measurement, making it a practical alternative for users who prefer a manual sphygmomanometer with digital readability.

Why Choose Dr. Odin OLS103?

Mercury-Free Design

The OLS103 uses a mercury-free pressure measurement system, providing an alternative to traditional mercury sphygmomanometers.

Clear LCD Readout

The device combines an LCD pressure column with a numerical display, helping users observe the measurement more clearly than a traditional analogue dial. The numerical display uses 1 mmHg graduation.

Manual Measurement Control

The user manually inflates the cuff using the latex bulb and controls pressure release through the air-release valve. This makes the device suitable for users trained in manual blood pressure measurement.

0–300 mmHg Range

The LCD column and numerical display both support a listed measurement scope of 0–300 mmHg.

D-Ring Cuff

The cotton cuff features a D-ring closure designed to help with secure positioning around the arm during measurement.

Battery & External Power Options

The device uses three AA batteries and the available specifications also indicate compatibility with a USB-type AC adapter.

How to Use Dr. Odin OLS103

Step 1: Prepare the Device

Insert 3 AA batteries correctly into the battery compartment if using battery power. Connect the cuff tubing to the pressure inlet.

Step 2: Position the Person

Have the person sit quietly and comfortably. The arm should be supported appropriately during measurement. Avoid talking or unnecessary movement during the reading.

Step 3: Apply the Cuff

Wrap the cuff securely around the upper arm according to the supplied instructions. Make sure the cuff is positioned correctly.

Step 4: Prepare the Stethoscope

Position the stethoscope appropriately to detect Korotkoff sounds during manual measurement.

Step 5: Inflate the Cuff

Press the bulb repeatedly to manually inflate the cuff.

Step 6: Release Pressure Gradually

Use the air-release valve to gradually reduce cuff pressure. The available instructions specify a deflation rate of approximately 2–3 mmHg per second.

Step 7: Determine the Reading

The appearance of the first Korotkoff sound corresponds to systolic pressure, while disappearance of the sound corresponds to diastolic pressure. Observe the LCD and numerical display while performing the measurement.

Step 8: Complete the Measurement

Fully release the remaining cuff pressure, remove the cuff and switch off the device after use.

Manual blood pressure measurement should be performed by a trained healthcare professional or by a user who has received appropriate instruction.

Important Blood Pressure Measurement Tips

For more consistent measurements:

• Sit quietly before taking the reading.
• Keep your arm properly supported.
• Use the correct cuff positioning.
• Avoid talking or moving during measurement.
• Release cuff pressure gradually.
• Use the same measurement procedure consistently.
• Take multiple readings when advised by your healthcare professional.
• Record readings when monitoring blood pressure over time.

Correct cuff placement and manual measurement technique are important because the OLS103 relies on stethoscopy and manual pressure control rather than fully automatic measurement.

Safety & Precautions

• Read the user manual before first use.
• Do not use the device if the cuff, tubing, bulb or display is damaged.
• Do not overinflate the cuff unnecessarily.
• Do not place the stethoscope chest piece underneath the cuff.
• Keep the device away from direct sunlight.
• Avoid sharp tools that could damage the cuff or tubing.
• Clean the device with a damp cloth.
• Do not use solvents for cleaning.
• Remove the batteries if the device will remain unused for an extended period.
• Store in a cool, dry location.
• Replace batteries when the low-battery indication appears.
• Keep the device away from children.

The manufacturer's care guidance specifically recommends avoiding sharp tools, direct sunlight and solvents, while storing the device in a cool, dry location and removing the battery when it will not be used for some time.

Who Can Use Dr. Odin OLS103?

The OLS103 can be suitable for:

• Doctors and healthcare professionals
• Clinics and consultation rooms
• Nursing students
• Medical students learning manual BP measurement
• Home users familiar with manual sphygmomanometer operation
• Healthcare facilities requiring a mercury-free manual BP monitor

It is particularly appropriate where a manual stethoscopic BP measurement method with an LCD readout is preferred.
