Description

A DEVICE FOR ATOMISING A LIQUID
BACKGROUND OF THE INVENTION
The present invention relates to a device for atomising a liquid.
Atomised liquids are used for many purposes. One such use is for therapy, for example, by application to the skin or by inhalation. One example is the atomisation of sodium chloride for inhalation to assist with the removal of mucus and debris from the lungs. Another example is atomisation of hyaluronic acid for skin beauty purposes.
An exemplary device for atomising liquids to form a mist is the PARI TurboBoy® SX. The device uses a compressor to supply compressed air into a housing containing an atomiser and atomisable liquid. A mouthpiece/face mask is attached to an outlet port on the device through which a user inhales the atomised liquid.
SUMMARY OF THE INVENTION
According to the present invention there is provided a device for atomising a liquid, the device comprising: a housing comprising a reservoir of liquid fluidly connected to an atomising nozzle and an outlet; a compressor
connectable to a gas source and fluidly connected to the housing by a first channel; a power source for the
compressor; and an oxygen concentrator comprising a second channel; wherein the device is arranged to supply
pressurised gas from the compressor through the first channel into the housing and onto the atomising nozzle to atomise the liquid in the reservoir to dispense it from the outlet as an aerosol plume; and wherein the device is further arranged such that the oxygen concentrator supplies an oxygen containing gas through the second channel to boost the oxygen content in the dispensed aerosol plume. The present invention thus provides a simple device for creating an oxygen enriched aerosol. The device may be arranged such that the second channel fluidly connects the oxygen concentrator into at least one of a position upstream of the nozzle, and the aerosol plume.
The device may be arranged such that the second channel fluidly connects the oxygen concentrator to the position upstream of the nozzle, wherein the device is then arranged such that the oxygen concentrator supplies an oxygen
containing gas through the second channel only into the position upstream of the nozzle.
Alternatively, the device may be arranged such that the second channel fluidly connects the oxygen concentrator to a second outlet in fluid communication with the aerosol plume, and wherein the device is then arranged such that the oxygen concentrator supplies an oxygen containing gas through the second channel only into the aerosol plume.
In this case, the outside of the housing may be inwardly tapered towards the outlet, and the downstream end of the second channel may terminate in an opening which extends around the outside of the housing, wherein oxygen containing gas from the opening is arranged to be supplied towards the outlet. In this way, the oxygen containing gas from the opening can pass along the outer surface of the housing toward the aerosol plume, by way of the Coanda effect.
Alternatively, the oxygen concentrator may supply an oxygen containing gas into both the position upstream of the nozzle and the aerosol plume by comprising a further channel to the second channel, wherein the second channel fluidly connects the oxygen concentrator to the position upstream of the nozzle, and the further channel fluidly connects the oxygen concentrator to the second outlet in fluid
communication with the aerosol plume.
Preferably the power source is a battery.
The device is preferably arranged to generate an aerosol plume which comprises droplets of a diameter of less than ΙΟμιη.
The liquid inside the reservoir may be a saline
solution, for example a solution of sodium chloride. In this way, the device is then useable to assist with the removal of mucus and debris from the lungs. The liquid may instead contain hyaluronic acid so that the device can be used for skin beauty purposes.
The device may further comprise a liquid inlet in fluid communication with the reservoir to allow the liquid in the reservoir to be refilled. The pressurised gas is preferably a breathing gas such as compressed air or helium (a mixture of helium and
oxygen) . The housing may be supplied as part of a single-use disposable cartridge. In which case, the compressor and the oxygen concentrator may be housed in a base unit for receiving the cartridge. In this case, the base unit may be connectable to the cartridge by a screw thread to securely connect the two components together.
The downstream end of the first channel may comprise a perforating means, and the cartridge may then comprise a perforable film that is upstream of the atomising nozzle and that can be perforated by the perforating means. This ensures that the cartridge is sealed prior to use. BRIEF DESCRIPTION OF THE FIGURES

With reference to Figure 1, there is shown an atomiser device 10 which comprises a cartridge 11 defining a
generally cylindrical housing 12 within which is located a reservoir 16 of atomisable liquid, and an atomising nozzle 14.
Extending from an outer edge of the housing 12 is an access channel 15 for allowing gas from outside of the cartridge 11 to enter the atomising nozzle 14.
An opening 18 is present on the housing 12 which is fluidly connected to the liquid contained in the reservoir 16 to define an outlet for the liquid from the cartridge 11. A closure means (not shown) , such as a valve or a peelable film, is located between the reservoir 16 and the opening 18 to control the flow of liquid through the opening 18 when the device is not in use. The cartridge 11 is supported in use by a base unit 13 which includes a compressor 20 connected to a supply 22 of air or other breathable gas. The compressor is powered by a power source 24, for instance a battery.
A gas channel 28 in the base unit 13 extends from the compressor 20 and is fluidly connectable with the access channel 15 of any cartridge 11 connected to the base unit 13. The gas channel 28 thus allows compressed gas from the compressor 20 to enter the atomising nozzle 14 of any connected cartridge 11.
An oxygen concentrator 26 containing an oxygen enriched gas is also located in the base unit 13. The oxygen
concentrator 26 is selectively connectable by a valve arrangement to one/both of two channels 31A;31B. The first channel 31A is fluidly connected to the gas channel 28 in the base unit to allow oxygen enriched gas from the
concentrator 26 to pass into the access channel 15 of any cartridge 11 connected to the base unit 13. The second channel 31B extends from the concentrator 26 to a vent 32 located in the vicinity of the opening 18 of a cartridge 11 connected to the base unit 13.
In use of the device 10, a cartridge 11 is connected to the base unit 13 so that the gas channel 28 of the base unit 13 fluidly connects with the access channel 15 of the cartridge 11. The base unit 13 is then operated such that the compressor 20 supplies gas into the atomising nozzle 14 of the cartridge 11 to atomise the liquid contained in the reservoir 16 such that the liquid forces open, and passes through, the closure means into the opening 18 and out of the device 10 as an aerosol spray/plume with droplets having a diameter of less than ΙΟμιη. Depending on which of the channels 31A;31B the oxygen concentrator is connected to, during the atomisation of the liquid in the reservoir 16, oxygen enriched gas is supplied into the gas channel 28 via channel 31A, and/or is supplied into the generated aerosol plume via channel 31B. In either operation however, an oxygen enriched aerosol plume is generated by the device 10. Another atomiser device 10' according to the present invention is shown in Figures 2A-2C. The structure and operation of device 10' is largely similar to the device 10 shown in Figure 1. As shown best with reference to Figure 2B, the device
10' comprises a base unit 13 connectable to a removable cartridge 11 via a screw thread 17.
The access channel 15 from the cartridge 11 is
connectable to the gas channel 28 from the base unit 13. The tip of the gas channel 28 is pointed to define a puncturing means 29 which is operable to pierce a film (not shown) located over the access channel 15 from the cartridge 11 when it is first connected to the base unit 13.
In the device 10', oxygen from the oxygen concentrator 26 is supplied into the generated aerosol plume via channel 31B. The vent 32 from this channel 31B defines a
circumferential opening which extends around a portion of the cartridge 11. Because of the circumferential shape of the vent 32, and the outside surface of the cartridge being inwardly tapered towards the opening, oxygen emitted from the vent 32 is forced along the outer surface of the
cartridge 11 towards the aerosol plume emitted from the opening 18. This effect of the oxygen being forced along the outer surface of the cartridge 11 is known as the Coanda effect. With this configuration, the length of the generated aerosol plume from the opening 18 is increased.
A further atomiser device 10'' according to the present invention is shown in Figures 3A-3B. The structure and operation of device 10'' is very similar to the device 10 shown in Figures 2A-2C. The cartridge 11 in this embodiment however is fixed to the base unit 13, and also comprises an inlet 34 fluidly connected to the reservoir 16 for topping up the liquid contained therein.
The liquid contained within the reservoir is any liquid which can be atomised. Exemplary liquids which can be used include a solution of sodium chloride for when the device is used assisting with the removal of mucus and debris from the lungs, and hyaluronic acid for use in skin beauty purposes.
