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.
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.
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.
Nozzles
Types of nozzles included in the delivery of the nebuliser.
—
The mask for adult. A mask is a dual-purpose nozzle covering both the mouth and nose, typically secured with a strap. It ensures effective drug inhalation, accommodating variations in breathing patterns. Masks are versatile, suitable for use during sleep or unconsciousness. However, their larger size may hinder portability when carrying them with a nebuliser (refer to "Purpose"). Despite their convenience, specialized devices offer higher aerosol concentration. This type of mask is tailored for the average adult.
—
Children's mask. Reduced version of the mask, designed for children. The design may provide additional decorative elements (see "Appearance for children"), and in terms of functionality and main features, such masks do not differ from the adults described above.
—
Nozzle for nose. A drug delivery nozzle for the nose typically features a distinctive "fork" shape with two separate protrusions inserted into the nostrils. These protrusions may gently compress the nasal septum, ensuring comfortable usage. These devices are particularly effective for treating conditions focused on the nasal cavity, such as rhinitis, as they provide a higher medicine concentration compared to masks. Additionally, nasal nozzles are more compact for easy storage.
— Nozzle f
...or mouth. An inhalation nozzle designed for drug administration through the mouth is a specialized device that offers a higher concentration of the active substance compared to a mask. This is particularly beneficial for intensive treatment of the oral cavity or larynx. Despite their small size, these nozzles are well-suited for use with pocket nebulisers. However, a drawback is the requirement for conscious patient participation, as they need to securely hold the tube with their lips and inhale through the mouth. While not as convenient as a mask, it somewhat restricts the application scope.
