Die Gesundheit der modernen Menschen wird durch die Zivilisationskrankheiten (chronische Krankheiten), wie Diabetes, Hypertonie, Hyperlipämie, Gicht usw., bedroht. Um diese Krankheiten zu vermeiden, ist neben der richtigen Ernährung und dem geeigneten Sport auch eine regelmäßige Gesundheitsuntersuchung erforderlich. Daher wurden verschiede tragbare bioglogische Meßgeräte, wie Blutzuckermeßgerät, elektronisches Ohr-Thermomenter, elektronisches Blutdruckmeßgerät, Cholesterinmeßgerät usw., entwickelt, die von dem Benutzer zuhause selbst betätigt werden können.The Health of modern people is caused by the civilization diseases (chronic diseases), such as diabetes, hypertension, hyperlipemia, gout etc., threatened. To avoid these diseases is next to the proper diet and the appropriate sport also a regular health examination required. Therefore, various portable bioglogic meters, such as glucose meter, have become electronic Ear thermometer, electronic blood pressure meter, cholesterol meter etc. developed by the user himself at home can.
