Frequently Asked Questions (FAQ)

Is there any situation where the use of shoulder and neck massager may not be recommended?

Please take note of the following warnings and precautions when using the shoulder and neck massager:
– The surface of the massager may become very hot, so individuals who are not heat-sensitive should use it with caution.
– The shoulder and neck massager should not be used as a substitute for medical treatment or to supplement it, as it may exacerbate chronic diseases and symptoms.
– If any of the following conditions apply, or if you have any doubts, consult your physician before using the massager: pregnancy, pacemaker, artificial joint, electronic implant, circulatory disorders, varicose veins, open wounds, bruises, skin damage, or phlebitis.
– If you feel any pain or discomfort during the massage, stop using the massager immediately and consult a physician.

Some tips to help you effectively maintain your shoulder and neck massager and keep it in good condition.

After use, please clean the massager with a clean cloth or a slightly damp sponge. Avoid using brushes, corrosive cleaning agents, oil-based cleaners, solvents, or alcohol as they may damage the device. Do not put the massager on a heater or use a hairdryer to dry it. The outer cover of the massage head can be removed for cleaning, following the instructions on the label. Always make sure that the device is completely dry before using it again.

Is there a specific time limit for using a shoulder and neck massager?

After 15 minutes, the device will shut off automatically. Please wait for the device to cool down completely before using it again to prevent overheating of the internal mechanism. Prolonged use of the device may shorten its lifespan and cause muscle tension instead of relaxation.

Is it possible for massage therapy to prevent the development of varicose veins?

To prevent varicose veins in the lower extremities, it is important to avoid prolonged standing and engage in more movement and exercise. Regularly tiptoeing can be beneficial as it helps in the contraction of the muscles of the calves, which can accelerate venous blood circulation and counteract the force of gravity on the blood. If there is an opportunity to sit down and elevate the feet, that is even better, as it reduces the gravitational force when the legs are in a flat position. Additionally, gently squeezing and releasing the leg muscles from bottom to top can be repeated to facilitate blood flow. Using a portable medisana cold/hot vibration massage gun can also help relax tense muscles, and relieve swelling and pain.

The medisana RG 220 has both cold and hot functions. Cold therapy helps to contract blood vessels. If you have varicose veins, using an ice pack for cold therapy can relieve swelling and discomfort. It’s especially important to avoid staying in high-temperature environments for too long in hot weather since it can cause blood vessels to dilate and worsen varicose veins. For people who work in high-temperature or sunny conditions for extended periods, applying cold therapy to the calves for 5 minutes every half hour can help contract the blood vessels.

Is it possible for a massage gun to be used as a treatment or for the improvement of varicose veins?

Nowadays, modern lifestyles lack sufficient exercise, leading to weight gain that puts additional pressure on the calves. If someone frequently stands for long periods, spider veins or small blue veins can easily appear on their calves. Unfortunately, many people underestimate the significance of this issue and consider it harmless. However, varicose veins in the lower extremities are a warning sign that should not be taken lightly. It is important to pay attention to these warning signs and take preventative measures to avoid further complications.

Leg massagers, similar to compression stockings, are only preventative and do not have any therapeutic function. They cannot “flatten” varicose veins, and in fact, in many cases of lower extremity varicose veins, they should not be used, particularly when the varicose veins have already taken on a worm-like appearance. Indiscriminate massaging could potentially cause congestion, blood clots, or calcified parts of the blood vessels to shift, resulting in thrombosis when they flow back into the lungs. This, in turn, can cause pulmonary embolism with a high mortality rate.
Varicose veins result from pathological changes in the veins and cannot be self-improved. If individuals have varicose vein problems, they should consult a physician to evaluate the appropriate treatment method and not believe in rumors.

Why does the screen display “Err”?

The temperature limit for use is 40°C. When the ambient temperature exceeds this temperature point, the LCD screen displays the error message “Err”. Please refer to the user manual for specific error messages for each model.

Why does the screen display HI/H and Lo/L?

When the temperature of the target object is higher than the measurement range, the LCD screen displays “HI” indication. When the temperature of the target object is lower than the measurement range, the LCD screen displays “Lo” indication. Please refer to the user manual for details of the measurement range.

What is the lifespan of the medisana infrared thermometer?

When designing new products, we conduct stress tests on key components to ensure a long lifespan. The design aims for a lifespan of 5 years under “normal” household usage conditions.

Is the medisana infrared thermometer suitable for use on animals?

medisana thermometers are developed and designed for human use. We do not have experience in animal measurements, and we do not assume any responsibility for the data obtained from animals.

How do I know if the thermometer remains accurate over time or after a fall?

The thermometer performs a functional check each time it is turned on. Therefore, as long as you do not receive an error message (“ERR”), correct usage will provide accurate results.

Does room termperature affect the readings?

No, as long as the operating temperature is between 10°C and 40°C (50°F and 104°F). If the thermometer is outside this range, measurements cannot be performed, and the display will show “L/Lo” or “H/Hi”. It may take some time for the thermometer to reach its operating conditions.

Why do different models of infrared thermometers give different measurement values?

Infrared thermometers can be easily affected by the environment and some factors that affect measurement stability. Additionally, different models of infrared thermometers have different temperature measurement components. For correct measurement methods and distances, please refer to the user manual for each model. When abnormal measurement results occur, it is recommended to measure again using a mercury thermometer or electronic mercury thermometer. Medisana infrared thermometers have been rigorously tested for accuracy to meet international standards, with an error generally not exceeding ±0.2°C – 0.4°C (depending on the mode).

How can I improve the accuracy of my thermometer measurement results?

It’s important to note that the performance of infrared thermometers can be influenced by the environment they’re used in. Therefore, it’s advisable to refer to the user manual to get the best usage methods. Generally, here are the recommended usage guidelines:
– The thermometer should be used in a non-ventilated space and kept away from direct sunlight or heat sources.
– The ambient temperature should be between 10 – 40 °C, and the relative humidity should be between 15 – 90% RH.
– Allow the thermometer to adapt to the surroundings by placing it in a stable environment for at least 30 minutes before use.
– Make sure that the detector is clean by using a cotton swab dipped in alcohol to clean it.
– Clean the area that requires measurement and remove any dirt, hair, or sweat.
– For forehead temperature measurement, direct the detector at the center of the forehead from a distance of 0-5 mm.

Why is there a difference in temperature measurements when taken from forehead and the ear?

Ear temperature measurements are considered more accurate than forehead temperature measurements because different parts of the body have varying temperatures. Ear temperature is closer to the true internal body temperature, while forehead temperature can be influenced by various factors such as outdoor sunlight and indoor air conditioning. The U.S. FDA also provides guidance that forehead temperature measurements can be more easily affected by environmental and operational factors. medisana infrared thermometers have undergone rigorous testing, and the accuracy of both ear and forehead temperature measurements under laboratory conditions (fixed room temperature and object temperature) is within ±0.2°C.

Can pregnant women use the body analysis scale?

It is not recommended for pregnant women to use the body analysis scale because during pregnancy, the body tends to have higher levels of fat and water, making the measurement unnecessary.

The maximum weight is 180kg, but does the scale fail to measure body fat and related data if the weight exceeds a certain limit?

Currently, the maximum weight capacity is 180kg. If the weight exceeds this limit, the scale will display “O-Ld,” indicating overweight, and it will not proceed to measure body fat and other data.
The display of measurement data is primarily influenced by age. As long as the user falls within the appropriate age range and the weight is within 180kg, relevant data can be measured.

Under what circumstances should the athlete mode be activated? How does the althlete mode affect the measurement results?

The athlete mode is primarily designed for athletes and uses specific algorithms. The criteria for activating the athlete mode are: exercising at least 3 times a week and having clearly defined muscles, such as visible six-pack abs.
When the athlete mode is activated, there will be significant variations in muscle mass, water content, protein, and other data to accommodate the body composition differences of athletes (athletes generally have higher muscle and bone mass than the average person).

Is the measurement of body fat percentage with a body analysis scale always accurate?

The Bioelectrical impedance analysis (BIA) method uses electrical impedance to estimate body fat percentage and other data. The estimation formula assumes that the relative proportions of muscle, water, and bone in the body are consistent for everyone. However, in reality, the proportions of these tissues vary among individuals, resulting in certain inaccuracies in the measurement results.
The body fat data obtained using the BIA method is not equivalent to data obtained through medical methods. It should be used as a reference for monitoring changes in one’s body fat percentage.

Why is there a significant difference in body fat when measured in different times?

Since over 70% of the human body is composed of water, it is important to consider the body’s hydration status when using the Bioelectrical impedance analysis (BIA) method to measure body fat percentage. Factors such as drinking excessive water before measurement, going to the bathroom, or engaging in intense exercise can greatly affect the measurement results.
To obtain more accurate measurements, please consider the following:
1. Do not eat or drink for at least 4 hours before measurement.
2. Avoid exercising for at least 12 hours before measurement.
3. Try to urinate before measurement.
4. Remove any metal objects from the body.
5. Keep hands and feet dry during measurement.
6. Measure at a fixed time and under consistent conditions every day.

What is the principle behind the measurement of body fat using the medisana Body Analysis Scale?

This product uses Bioelectrical Impedance Analysis (BIA) to measure body fat content. The electrodes on the scale emit a small electrical current through the body for measurement. Different tissues in the body have different levels of resistance to the current (fat tissue has weaker conductivity). Therefore, the body analysis scale, along with preset equations and data such as gender, height, weight, and age, can measure and estimate parameters such as body water, fat percentage, muscle mass, bone mass, and BMR.

Why do measurement results of medisana blood pressure monitors differ from those of other brands? Are they inaccurate?

The accuracy of this product has been confirmed according to clinical standards. Clinical comparisons are made by measuring the blood pressure of the same person using our blood pressure monitor and comparing it with auscultatory blood pressure measurements. Therefore, the measurement results of other brands of home blood pressure monitors cannot be used as a comparison standard for our blood pressure monitor.
The results measured by users at different times, in different environments, or under different physical conditions can also vary, making such comparisons subjective.
If you measure blood pressure five times using a certain brand’s blood pressure monitor, the results will also differ each time, showing a deviation. Similarly, if you measure five times using our blood pressure monitor, you may get five different results. In these cases, the comparisons are not valid due to the inherent deviations.

Can medisana blood pressure monitors be used by pregnant women or infants?

This product is intended for adult use and is not suitable for pregnant women, children, infants, patients with implanted electronic devices (such as pacemakers or defibrillators), patients with pre-eclampsia, ventricular premature beats, atrial fibrillation, peripheral arterial disease, patients undergoing endovascular treatment or arteriovenous shunting, or patients who have undergone breast surgery.

Can the cuff of the blood pressure monitor be cleaned?

The cuff should not be washed and should be kept away from moisture. If the cuff is faulty, it can be replaced with a new one.

Should blood pressure be measured on the left or right arm?

For the first use, measurements should be taken on both arms, and the arm with the higher blood pressure should be used for future measurements as the preferred arm.

Why do the values measured at home tend to be lower than those measured in the hospital?

The values measured at home may differ from those measured in the hospital by approximately 20-30 mmHg. This is because people generally feel more relaxed when measuring blood pressure at home, while many individuals feel more anxious in a hospital environment.
Additionally, if the cuff is placed at a higher level than the heart during measurement, the measured values will generally be lower. Therefore, please ensure that the cuff is placed at the same level as the heart.

How often should blood pressure be measured?

Blood pressure gradually rises within 2 hours after waking up and slowly decreases before bedtime. Therefore, the best times to measure are in the morning just after waking up, and in the evening before going to bed.
Blood pressure can vary significantly at different times, so it’s important to measure at a fixed time period to ensure consistency. Additionally, make sure to measure before taking any blood pressure medication.

Why is there a significant deviation in the measured values?

When measuring blood pressure, pay attention to the following points:
– Relax before measuring blood pressure. It’s best to sit down and rest for 10-15 minutes before measurement, waiting for a stable heartbeat before proceeding. Stay focused during the measurement and avoid moving or talking.
– The cuff should be at the same level as the heart, with the palm facing up, and should not be clenched into a fist.
– Choose a chair with a backrest if possible, keep your feet on the ground, and avoid crossing your legs.
– Avoid caffeine, smoking, or alcohol before measurement.
– Measure blood pressure at the same time every day.
– When wearing thin clothing, you can measure directly. If wearing thick clothing or a coat, remove them first.
– Do not measure repeatedly in a short period of time, as it can cause arm congestion and inaccurate results. Allow a 3-minute interval between each measurement.
– Pay attention to the correct placement of the cuff. Looseness or looseness can result in inaccurate measurements.
– Avoid measuring blood pressure after exercise, bathing, or meals.
– For morning measurements, it is recommended to measure after using the toilet, as blood pressure tends to be less stable when there is a need to urinate or have bowel movements.

When is the best time to measure blood pressure?

Blood pressure gradually rises within 2 hours after waking up and slowly decreases before bedtime. Therefore, the best times to measure are in the morning just after waking up, and in the evening before going to bed.
Blood pressure can vary significantly at different times, so it’s important to measure at a fixed time period to ensure consistency. Additionally, make sure to measure before taking any blood pressure medication.
