Problems solved by technology

[0003] Ordinary hydraulic / pump-actuated nasal aspirators emit or spray large drops of liquid into the nostrils. These droplets are polydisperse, that is, the spectral line of the droplet size is broad. Deposition mainly depends on its own inertia, which will make the distribution of liquid very uneven
Depositing too many droplets at one site can cause the droplets to coalesce and flow out of the nostrils or down the back of the throat, causing a nasty taste, or worse, as the anesthetic enters the digestive or pulmonary systems harmful side effects

Embodiment Construction

[0038] As shown in Figure 1, the nasal aspirator 1 embodying the present invention is mainly used as a pocketable hand-held device that is manipulated by the user to deliver active substances or medicines into the patient's nostrils, for example, the nasal aspirator can be used A decongestant (eg, oxymetazoline hydrochloride) is delivered into the nasal cavity or an anesthetic or other drug such as insulin or 2,2,3-trimethylbutane (eg Elitroptan) is delivered through the nasal mucosa into the bloodstream. This nasal aspirator can also be used to deliver a kind of influenza vaccine such as Flumist (product developed by Avivonof Mountain view, California, USA) that is effective at a lower temperature of the nasal mucosa into the patient's nasal cavity.

[0039]The nasal aspirator has a housing 3 mainly made of electrically insulating material such as plastics, at least that part of the housing 3 that is inevitably in contact with the user in use is a conductive area that can be g...

Abstract

An inhaler has a housing containing a chamber (1a) providing a reservoir (8) for liquid providing an active ingredient to be supplied to a liquid outlet (10a). First and second electrodes are spaced apart (11 and 12) with the first electrode being spaced apart (11 and 12) with the first electrode being provided at or adjacent the liquid outlet (10a). A voltage supply (5, 7) is activated in response to air flowing through an air inlet (30) of the housing to provide a potential difference between the first and second electrodes (11 and 12) to create an electric field for causing comminution of liquid issuing from the liquid supply outlet (10a) to produce a stream of electrically charged comminuted matter for supply to the nasal passages of a user via an outlet (4) of the housing.

Description

technical field [0001] The present invention relates to nasal aspirators for delivering active substances into the nasal cavity. Background technique [0002] Nasal aspirators are commonly used to deliver decongestants such as oxymetazoline hydrochloride and the like. The nasal cavity is also a good way to deliver anesthetics and other medicines into the bloodstream for diseases that do not belong in the nasal cavity. [0003] Ordinary hydraulic / pump-actuated nasal aspirators emit or spray large drops of liquid into the nostrils. These droplets are polydisperse, that is, the spectral line of the droplet size is broad. Deposition mainly depends on its own inertia, which will make the distribution of liquid very uneven. Depositing too many droplets at one site can cause the droplets to coalesce and flow out of the nostrils or down the back of the throat, causing a nasty taste, or worse, as the anesthetic enters the digestive or pulmonary systems Harmful side effects.
