Why home medical devices are important
Home medical devices have become an indispensable part of everyday life, especially for people with chronic diseases such as diabetes, hypertension or asthma. Regular monitoring of glucose levels, blood pressure or respiratory function allows for faster response, better symptom control and reduces the need for frequent visits to the doctor.
The most commonly used devices in home care are glucometers , blood pressure monitors , and inhalers/nebulizers . In this guide, we provide a detailed explanation of how each of these devices is used, what to look out for, and how to ensure accurate and reliable results.
Glucometer – what it is and how it works
A glucometer is a small medical device designed to measure blood glucose levels. People with diabetes depend on accurate results from their glucometer to properly dose their medication. Modern technology has made glucometers fast, accurate, and easy to use.
When to use a glucometer?
Blood sugar testing is recommended:
-
before meals
-
2 hours after a meal
-
before bed
-
in case of hypoglycemia or hyperglycemia
-
before and after physical activity
-
on the recommendation of a doctor
That's why it's important to know how to use a glucometer properly so that the results are accurate.
How to use a glucometer correctly (step-by-step)
-
Wash your hands with warm water and soap.
Grease, dirt or food residue can affect the result. -
Prepare everything you need:
– glucometer
– test strip
– lancet
– cotton wool or handkerchief -
Insert the test strip into the glucometer.
The device will activate automatically. -
Disinfect the tip of your finger and wait for it to dry.
-
Use a lancet for a light prick.
Pinch your finger to get a drop of blood. -
Apply blood to the test strip.
Most devices automatically draw the required amount. -
Wait a few seconds.
The result will appear on the screen. -
Record the result or sync with the mobile app.
The most common errors in glucose measurement
-
fingers are not clean or are wet
-
outdated test strips
-
improper storage of strips
-
insufficient blood volume
-
cold hands
Proper use of a glucometer is essential for monitoring health status and selecting therapy.
Correct use of a blood pressure monitor
Blood pressure monitors are among the most important medical devices for home use, especially for people with hypertension. Electronic and mechanical models are available.
Electronic blood pressure monitors (automatic)
Electronic blood pressure monitors are easy to use and display the result in a few seconds.
How to use an electronic blood pressure monitor:
-
Sit comfortably and relax for a few minutes.
-
Place the cuff on your upper arm or wrist, depending on the model.
-
Keep your hand at heart level.
-
Turn on the device and wait for the measurement.
-
Record your systolic and diastolic blood pressure values and your pulse.
Mechanical pressure gauges (analog)
These devices are used with a cuff, pump, and stethoscope. They are more accurate, but require skill and experience.
How to use a mechanical blood pressure monitor:
-
Sit in a quiet environment.
-
Fit the cuff firmly, but not too tight.
-
Pump air until you exceed the expected pressure values.
-
Slowly release the air and listen for the sounds through the stethoscope.
-
First sound = systolic pressure, disappearance of sounds = diastolic pressure.
How to get the most accurate results?
-
measure your blood pressure at the same time every day
-
avoid caffeine 30 minutes before measurement
-
do not talk during the measurement
-
repeat the measurement twice and take the average
When to use an inhaler or nebulizer?
Inhalers and nebulizers are used to treat respiratory diseases, such as asthma, bronchitis, or COPD. Both devices have the same purpose – to deliver medication to the lungs – but they work in different ways.
Inhalers
Inhalers are small, portable, and convenient for quick administration of medication. There are:
-
MDI – metered dose inhaler
-
DPI – powder inhaler
-
Soft mist inhaler
How to use the inhaler:
-
Shake the device (if it is an MDI).
-
Exhale slowly.
-
Place the inhaler in your mouth and press the trigger.
-
Take a deep breath.
-
Hold your breath for 5–10 seconds.
Nebulizers
A nebulizer converts liquid medication into a fine mist that the patient inhales through a mask or mouthpiece. They are ideal for:
-
children
-
elderly people
-
severe asthma attacks
-
home therapy
How to use a nebulizer:
-
Insert the medicine into the container.
-
Connect the compressor, tubing and mask.
-
Turn on the device.
-
Breathe slowly for 5–10 minutes.
Tips for maintaining medical devices
Regular maintenance extends the life of the device and ensures accurate results.
Glucometer:
-
change lancets after each use
-
Store test strips in a dry and dark place.
Pressure gauge:
-
check the calibration periodically
-
Clean the cuff according to the manufacturer's instructions.
Inhaler/nebulizer:
-
wash the mask and mouthpiece after each use
-
Disinfect the components according to the instructions.
When to seek medical help?
Contact your doctor immediately if:
-
glucose results consistently deviate from expected
-
blood pressure remains high for several days in a row
-
you have difficulty breathing and the inhaler is not helping
-
symptoms get worse or last longer than usual
Medical devices are an aid, but not a substitute for professional diagnosis.
Conclusion
Home medical devices – glucometers, blood pressure monitors and inhalers/nebulizers – are essential for monitoring chronic diseases and maintaining health. Proper use of these devices ensures accurate results, faster response to symptoms and greater safety in everyday life.
