Clinical thermometer

Different types of clinical thermometers work according to different principles. On the one hand, there are contact thermometers, which determine the temperature through direct body contact. This variant includes, on the one hand, expansion thermometers. These contain a liquid metal mixture. When the temperature rises, the metal expands and moves along an imprinted temperature scale. Digital thermometers are another form of contact thermometer. In their measuring tip there is a sensor. The result is shown on a display.
Infrared thermometers work almost contactless. With these, an infrared sensor measures the radiation. The device converts the values into a temperature. Here, too, the readings are shown on a display.
There are two groups: contact thermometers and infrared thermometers. The former includes expansion thermometers, which consist of a glass body in which there is liquid metal. A digital clinical thermometer is also considered a contact thermometer. Different measuring methods are possible with both variants.
The second group is made up of clinical thermometers, which enable an almost contactless measurement by means of infrared. This is divided into ear thermometers, where the measurement takes place in the ear, and forehead thermometers, which you point at the forehead to measure. There are also practical devices that come with an attachment that allows you to turn the ear thermometer into a forehead thermometer.
There are also basal thermometers. These measure the body's waking temperature to two decimal places. This variant is mainly used in the symptothermal method, a natural form of contraception in which the woman calculates her fertile days on the basis of her body temperature and the consistency of the cervical mucus. Accordingly, a basal thermometer can also be helpful when planning pregnancy.
The measurement time depends on the type of thermometer. While an infrared thermometer provides you with the measurement results within seconds for both ear and forehead measurement, the temperature measurement with a contact thermometer takes several minutes.
If you use an electronic thermometer, the measurement time varies from device to device. You can find information on this in the manufacturer's instructions for use. Many models conveniently emit a signal tone when the measurement is finished.
With expansion thermometers you have to keep an eye on the time yourself. The measurement time depends on the measurement method - i.e. on which part of the body you are taking the temperature:
rectally - about four minutes
oral - about five minutes
axillary - eight to ten minutes
Contact thermometers, on which you can read the result digitally, offer you the highest measurement accuracy. The rectal measurement is particularly precise. But the measurement under the tongue is also relatively accurate. When measuring in the armpit, inaccuracies can quickly occur, as you usually do not succeed in pressing your arm against your body the entire time.
Infrared thermometers have the advantage that they measure the temperature within seconds. The measurement in the ear canal also provides good results. However, these can be falsified, for example, by a middle ear infection. Wrong measurements sometimes occur with forehead thermometers.
Taking a temperature in the bottom with a digital thermometer is also the most reliable option for babies. Measuring under the tongue and under the armpit is only suitable for children from the age of four and six years respectively.
Rectal measurement is usually unpleasant for the little ones and requires some parental skill. If your baby is older than three months, you can also use an ear thermometer. The quick measurement saves both children and parents some stress. With a forehead thermometer, you can take a temperature even when your baby is asleep, sometimes within just one second. However, the measuring accuracy is lower than with the digital thermometer.
There are also so-called pacifier thermometers especially for babies. As the name suggests, these are pacifiers with an integrated thermometer. In theory, this measures the body temperature while your child sucks on it. In practice, however, this does not work so well, because the pacifier does not reach far enough into the mouth and babies usually do not keep it long enough in the closed mouth.
For adults, the recommendation is quite clear: digital thermometer. It is best to use this for rectal measurement in the anus or oral under the tongue.
For measuring children, insert the rectal thermometer carefully one centimetre. For adults, it should also be one to two centimetres.
You clean the measuring tip of contact thermometers with warm soapy water and a cloth. Disinfection is particularly important after rectal measurement. It is best to use a cotton pad soaked in rubbing alcohol for disinfecting and hygienic care of the device.
Ear thermometers usually have disposable protective caps that you change after each measurement. If not, treat them carefully with rubbing alcohol.
Many devices draw their energy from button cells with a voltage of 1.5 volts. Some require AAA batteries as a power source and others AA batteries.
You can find detailed information about the type of batteries and how many batteries each model requires in the product descriptions or in the manufacturer's instructions.
If you're getting rid of your old thermometer that contains mercury, the regular garbage can is not the way to go. The liquid metal, when released, is harmful to both human health and the environment. For this reason, clinical thermometers with mercury belong in hazardous waste or toxic waste collection.
You can put digital and infrared thermometers in the residual waste. However, it is more exemplary if you dispose of them as electrical waste.
Empty batteries have no place in household waste. Dispose of them in the designated collection boxes in a supermarket or drugstore near you.
