Design for kids
This category includes nebulisers made in a characteristic
"childish" design. Such a design may include bright colours, additional decorative details (for example, in the form of figurines) and even the original shape of the entire body of the nebuliser — in the form of an animal, a fairy-tale castle, etc. Also included are models that are regularly produced in the "adult" version, but also have a "childish" colour version.
Medicine container
The nebuliser's built-in medicine reservoir volume is a crucial consideration. It's important to align this parameter with medical guidelines for the prescribed treatment. A too-small capacity may require frequent refilling, disrupting the treatment process.
Also, knowing the volume of the reservoir and the nebulization rate (see below), it is possible to estimate the operating time of the nebuliser on a single refill.
Compressor power
The power consumed by the compressor of the nebuliser during operation; in this case, it means not only the corresponding element of compressor models (see "Type"), but also the nebulizer in ultrasonic devices.
The performance and power consumption of the nebuliser depend on this parameter. The more powerful the compressor, the higher the possible air flow rate and, accordingly, nebulization. At the same time, powerful devices consume more power (which is especially important when powered offline, see below) and can generate quite a lot of noise.
Max air flow
The maximum air output of a compressor nebuliser during operation is a key factor to consider. It's important to note that actual performance during normal operation is often lower. Different applications have recommended air flow intensities, and knowing this parameter helps assess how well the inhaler aligns with specific recommendations.
Nebulization rate
The nebuliser's nebulization capacity per minute.
The ideal nebulization rate can differ based on factors such as the patient's health condition, the type of disease, and the composition of the inhaled medication, as outlined in medical guidelines. This rate is crucial in assessing the inhaler's effectiveness for specific situations and also influences how long the device operates on a single medication refill.
Some models have a nebulization speed control — in such cases, the maximum value is usually indicated in the characteristics.
Medium particle size (MMAD)
Since not all particles have the same size, this paragraph indicates exactly the average, most common particle size when splitting in this inhaler. Accordingly, lower values allow easier and deeper penetration into the bronchi.
Particle size changing
Possibility
to change the size of the particles created during the nebulization of the medicinal product. See above for size value. Here we note that high penetrating power is not always required: for some diseases (for example, inflammation in the larynx or trachea), it is not necessary to deliver the medicine deep into the bronchi. Accordingly, by changing the particle size, it is possible to control the delivery distance.
Noise level
The nebuliser's maximum noise level during normal operation is a crucial factor for user comfort, especially in situations where loud sounds are undesirable, such as when treating children or during nighttime use. It's important to note that the relationship between decibel levels and actual perceived noise is not linear. For instance, a 3 dB increase corresponds to a doubling of noise, and a 20 dB increase equals a 100 — fold increase in noise. Comparative tables are often used to assess the actual loudness of inhalers, and here are some relevant values for modern devices:
30 dB — comparable to a whisper, the maximum permissible noise level in residential premises at night according to sanitary standards;
35 dB — talking in an undertone;
40 dB — normal speech at a distance of about 10 m;
45 dB — conversation in a normal voice;
50 dB — a conversation is slightly louder than usual, it is considered the maximum noise level that does not cause noticeable inconvenience;
55 dB — car engine;
60 dB — TV at medium volume;
65 dB — loud conversations at a distance of up to 1 m.
Accessory compartment
Having an
accessory compartment in the nebuliser case, including nozzles and power cords, significantly streamlines storage and transportation. This design ensures that all essential components are neatly housed within the case, minimizing the risk of loss and keeping everything organized.
