The present invention relates to a handheld nebulizer and the use of such a device for administering medication to a patient, and the like.
A jet nebulizer, also referred to as an atomizer, forces compressed gas to flow through a liquid, causing the liquid to aerosolize. This aerosol can then be inhaled by a patient. Relative to other technologies such as electronic cigarettes, where a heat source is used to vaporize a liquid, this process has little to no effect on the chemical composition of the material being atomized.
One common drawback of commercial nebulizers is that they use plastic or rubber components in their construction. As a result, they are not capable atomizing thick compounds such as heavy oils or glycerin based compounds. In addition to not being able to withstand the pressure required to nebulize these compounds over extended use, these non-durable components are also susceptible to corrosion if the liquid is in any way caustic.
As a result of these drawbacks, patients have been unable to reliably use nebulizers to inhale medicinal cannabis based medications that are suspended in glycerin or heavy oils. Furthermore, the mildly caustic nature of many essential oils and cannabis based medications means that they are also inappropriate for use in the nebulizers that are commercially available today.
The above discussed disadvantages of the prior art are overcome by a nebulizer of the present invention that is fortified to withstand the pressures required to aerosolize heavy liquids such as heavy oils or glycerin.
Thus it is one aspect of some embodiments of the present invention to provide a nebulizer that lacks non-durable components, such as those made of plastic or rubber. In certain embodiments of the present invention, the components that comprise the nebulizer are made of a durable metal, such as stainless steel, or glass. In other embodiments, rubber gaskets may be replaced with Teflon equivalents.
It is another aspect of certain embodiments of the present invention to provide a medicinal cannabis based medication for use by a patient. In certain embodiments, such medication will comprise a substantially pure cannabidiol (CBD) extract suspended in a glycerin solution. In certain embodiments such a medication will comprise essential oils with medicinal properties, such as frankincense, in a glycerin solution.
Thus, one embodiment of the present invention provides, a method treating a patient with an aerosolized solution, the method comprising: i. placing the solution into the reservoir of a nebulizer; ii. forcing a gas into the solution; iii. inhaling the aerosolized solution; wherein the solution comprises at least one of a heavy oil and a glycerin based liquid, wherein the at least one of a heavy oil and a glycerin based liquid comprises a medication; wherein the nebulizer consists substantially of materials that are resistant to high pressure and corrosion; and wherein the nebulizer reservoir comprises an open end and a closed end, wherein said open end is removably attached to the aerosol generator, and said aerosol generator is attached to said reservoir such that said aerosol generator is nested within said reservoir;

Cannabidiol (CBD) is a chemical that is commonly extracted from plants of the cannabis genus. One method of extracting CBD and a description of its properties is disclosed in US Patent Application No. 20060167283. Due to the presence of trace amounts of the acidic variant of cannabidiol (CBDA) present in most samples, even substantially pure CBD extract is mildly caustic, and thus unsuitable for use in traditional nebulizers. CBD has the following chemical structure:
Treatment with CBD can provide numerous benefits. For example, 3 mg-10 mg of CBD can provide relief to Arthritis symptoms, inflammation, and pain; 25 mg-50 mg can provide relief of stress and anxiety symptoms; and 100 mg-200 mg per day can control many forms of epilepsy. As such, in certain embodiments of the present invention various concentrations of a substantially pure CBD extract are provided. These contractions range from 0.5 mg/mL, 1 mg/mL, 3 mg/mL, 10 mg/mL, 25 mg/mL, 50 mg/mL, 100 mg/mL, 200 mg/mL, 500 mg/mL, and 1000 mg/mL of substantially pure CBD to liquid base. Preferably, the liquid base will be oil or glycerin based. More preferably, the glycerin may be partially diluted with water. Most preferably, the glycerin to water ratio will be 8:7.
