Essential differentiation criteria for secretion aspiration devices are:
- Size and weight
- Suction capacity (litres per minute)
- Absorption capacity of the secretion container
- Operation via mains / battery
Depending on the application, three different device versions are recommended:
- Mains-powered, electrically operated suction units are mainly suitable for home use.
- Mains-independent, battery-powered suction units are ideal for travelling; they are portable, have a rechargeable battery and are therefore mainly suitable for mobile use.
- Manual suction pumps are designed for emergency use. They do not require any power supply at all and are operated either by hand or by a foot pedal.
Decisive for the right choice is also the frequency of the suction requirement and the required suction power (for viscous or liquid secretions).
Septic fluid aspirators are also offered as combination devices, which additionally allow inhalation. After laryngectomy or a tracheotomy and thus the loss of the natural moisture retention of the mucous membranes, other precautions are necessary to prevent severe irritation of the mucous membranes. In most cases, such irritations lead to increased secretion, coughing, encrustation and barking.
