Read instructions carefully before using and save for future reference.

General Safety: This MDF® stethoscope is designed exclusively as a non-invasive medical auscultation instrument to detect heart and lung sounds on healthy skin around the external thoracic region. Due to its sound amplification function, it may cause damage to user’s ears if used other than its intended medical diagnostic purpose. Keep out of reach of children.

General Usage: MDF® stethoscope with ErgonoMax™ headsets are ergonomically pre-angled. Models with AccuFit™ headsets are anatomically adjustable for best fit, comfort, and sound transmission. A headset adjusted to a 15° forward angle is standard, and should be worn with the eartips pointed away from you if it is held directly in front of you. The dual-head chestpiece (excludes 727) contains a diaphragm side for detecting high-frequency sounds, and a bell side for detecting low-frequency sounds. According to the auscultation need, simply turn the fully-rotational acoustic valve stem to select the proper side of the chestpiece (excludes 727). Hold the chestpiece firmly against the desired auscultation location on the patient's external thoracic region. Prior to each use, make sure all parts are securely fastened and properly connected.

General Cleaning & Care: Clean stethoscope thoroughly before each use. Use a clean cotton cloth or swab and isopropyl alcohol solution to cleanse all soiled parts.

Avoid prolonged exposure of acoustic tubing to excessive heat, cold, solvents, moisture and oils/lipids (secreted by human skin).

Our commitment to high-quality instruments is backed by a lifetime warranty.

Adult Bell Attachment: Auscultation of low frequency sounds on adult patients.

Pediatric Bell Attachment: Auscultation of low frequency sounds on pediatric patients.

Infant Bell Attachment: Auscultation of low frequency sounds on infant patients.

Infant Diaphragm Attachment: Auscultation of high frequency sounds on infant patients.

Select attachment, screw clockwise and turn the acoustic valve stem to desired side of the chestpiece. Hold the chestpiece firmly against the desired location on the patient's external thoracic region. Prior to each use, make sure all parts are securely fastened and properly connected.

General Cleaning & Care: Clean stethoscope thoroughly before each use. For chestpiece, acoustic tubing, and ComfortSeal™ eartips, use clean cotton cloth or swab and rubbing alcohol or isopropyl alcohol solution to cleanse all soiled parts. Avoid prolonged exposure of the acoustic tubing to excessive heat, cold, solvents, moisture, or oils/lipids (secreted by human skin).

Read instructions carefully before using and save for future reference.

General Safety: This MDF® stethoscope is designed exclusively as a non-invasive medical auscultation instrument for the detection of heart and lung sounds on healthy skin around the external thoracic region. Due to its sound amplification function, it may cause damage to user’s ears if used other than its intended medical diagnostic purpose. Use only if you are a medical professional and do not leave stethoscope unattended around children.

General Usage: MDF® stethoscope headsets are angled anatomically for best fit, comfort, and sound transmission. The headset should be worn with the eartips pointed away from you if it is held directly in front of you. Hold the chestpiece firmly against the desired auscultation location on the patient's body. Prior to each use, make sure all parts are securely fastened and properly connected.

Adjust Time: Turn outer bezel counter-clockwise to remove the liquid crystal analog (LCA) quartz-timing device (Figure A). Insert end of pointed object (pen or paper clip) into time adjustment opening (Figure B). The second hand will automatically reset to the 12 o’clock position while the minute hand and hour hand will rotate clockwise. Simply release pointed object from time adjustment opening when desired position is reached.

Replace Battery: Turn outer bezel counter-clockwise to remove the liquid crystal analog (LCA) quartz-timing device (Figure A). Turn device over (Figure C) and remove metal backing by loosening the small screw first (Figure D) to expose and replace battery. Please use a AG-3/1.5 volt battery.

General Cleaning & Care: Clean stethoscope thoroughly before each use. For chestpiece, acoustic tubing, and ComfortSeal™ eartips, use clean cotton cloth or swab and rubbing alcohol or isopropyl alcohol solution to cleanse all soiled parts.

MDF®848 Series Palm Aneroid Sphygmomanometer(MDF®848, MDF®848XP, MDF®848XPD, MDF®848AR, MDF®848IC)

Read instructions carefully before use and save for future reference.

General Safety: MDF® sphygmomanometers are designed exclusively as a non-invasive method of measuring blood pressure on healthy skin of the upper arm or thigh regions only and always use as directed.

WARNING:

No modification of this equipment is allowed.

Do not inflate past 300 mmHg

Limit use to less than 2 minutes

Do not leave cuff inflated on arm or thigh

Do not leave unattended around children

An accuracy of ±6 mmHg (0.75kPa) is permitted under conditions of reasonably extended tem- perature ranges, such as might occur in ambulances or outdoors.

Intend use: The Aneroid sphygmomanometers by MDF Instruments Medifriend are designed as a non-invasive method of measuring blood perssure on healthy skin of the upper arm or thigh regions only. Patient only, used by medical purpose.

General Usage: Prior to each use, make sure all parts are securely fastened and properly connected. Always use with a stethoscope for accurate and complete blood pressure measurement(stethoscope is included with MDF®808 only).

Cuff Placement: Place cuff midway between shoulder and elbow with a gap of 2 to 3cm above the elbow. Locate the brachial artery pulse with first two fingers and place cuff so the arrow of the arterial indicator is directly over the brachial artery. The cuff should be at the same height as the heart.

Cuff Inflation: Screw valve clockwise to shut air release valve. lnflate cuff to 20-30 mm above expected systolic pressure.

Stethoscope Placement: Place the eartips of stethoscope into ears. The headset should be worn with the eartips pointed away from you if it is held in front of you. Place the chestpiece of the stethoscope firmly and directly over brachial artery underneath the cuff. If the pulse is heard prior to releasing the valve, inflate the cuff another 20 mmHg or until no pulse is heard.

Measurement: Screw valve counter-clockwise to release valve at a rate of 2-3 mmHg per second. The systolic pressure is the gauge reading at the first audible pulse. Continue with air release. The diastolic pressure is the gauge reading at the last audible pulse.

General Cleaning & Care: Clean soiled parts of sphygmomanometer thoroughly before each use. All parts of the sphygmomanometer and stethoscope can be cleaned with a clean cotton cloth and isopropyl alcohol solution or water with mild detergent. Do not let any liquid enter the inside of sphygmomanometer. Cuff cover can be hand washed with warm water and mild detergent. Air dry; do not machine dry.

Never inflate past 300 mmHg

Keep sharp objects away from cuff

Never disassemble the sphygmomanometer

Avoid impact or shock to the sphygmomanometer

Always deflate cuff completely after measurement and prior to storage

Avoid prolong exposure to excessive heat, cold, solvents, moisture, and oils

The pointer of a calibrated gauge will rest on the zero at no pressure

If pointer does not rest on zero, please contact the manufacturer at MDFinstruments.com for an authorized service center near you

Frequently check for and remove dust from screen filter of intake valve at end of inflation bulb

The sphygmomanometer should be stored between -20 °C and 70 °C and at a relative humidity of 15% to 85%

The sphygmomanometer should be used at temperatures between 10 °C and 40 °C and at a relative humidity of 15% to 85%

Technical Specifications:

Range: 0-300 mmHg

Accuracy: +/- 3 mmHg

This device complies with EN ISO 81060-1:2012

Your device should be checked for proper calibration and performance every two years. Please contact Authorized Representative in European Community below for the service center near you. Do not attempt to calibrate or repair this device yourself.

Maintenance and Calibration Specifications:

The sphygmomanometer should be calibrated at temperature range of 15 °C to 25 °C and at a relative humidity range of 15% to 85%.

The sphygmomanometer should not leak air in excess of 4 mmHg/min (0.5kPa/min) when the valve is closed.

The maximum error of the measurement of the cuff pressure at any point of the scale range should be within ±3 mmHg (±0.4 kPa).

Our commitment to high-quality instruments is backed by a three-year warranty on the gauge, cuff, bladder, and bulb, and lifetime calibration warranty on the gauge.
