Inert Polypropylene Filter for Medicinal Vapor Particulate Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing filtration systems for medicinal vapors, particularly those using cellulose or cellulose acetate filters, inefficiently remove smoke particles and tar while also adsorbing significant amounts of desired volatilized medicinal compounds like cannabinoids, and fail to prevent cross-contamination in group settings.
Innovation Solution
Implementing a chemically inert filter, such as one made from polypropylene, with a thin cross-sectional thickness and flexible design to physically remove particulate matter without interfering with volatilized medicinal compounds, and allowing for individual use to minimize cross-contamination between patients.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If cellulose or cellulose acetate filters are used to remove smoke particles and tar, then particulate matter is removed, but significant amounts of desired volatilized medicinal compounds are adsorbed and lost
Solution Approach 1:
The patent employs an inert filter material that does not chemically react with or adsorb volatilized medicinal compounds. The filter creates an inert environment for the vapor passage, allowing medicinal compounds to pass through without being retained, while still providing physical filtration of particulate matter through its structural properties.
Solution Approach 2:
The filter utilizes a porous structure with specific pore size and distribution that allows volatilized medicinal compounds to pass through while trapping larger particulate matter. The porosity is engineered to differentiate between the size of medicinal vapor molecules and smoke particles/tar, achieving selective filtration without chemical adsorption.
2Device complexity
If a common medicinal vaporizer mouthpiece is shared among patients, then device simplicity is maintained, but cross-contamination between patients occurs
Solution Approach 1:
The patent segments the mouthpiece into two distinct parts: a permanent base mouthpiece and a removable, disposable filter component. Each patient receives a personalized filter that can be attached to the shared vaporizer, creating individualized barriers that prevent cross-contamination while maintaining the simplicity of a single vaporizer device.
Solution Approach 2:
The patent implements disposable filters that are inexpensive and single-use. Each patient receives a new filter for each session, which is discarded after use. This eliminates the need for cleaning and sterilization of the mouthpiece between patients, ensuring hygiene safety while keeping the overall system simple.
3Object-affected harmful factors
If traditional filtration systems are used, then smoke particle removal is achieved, but the filter material chemically interacts with and removes medicinal compounds
Solution Approach 1:
The patent employs an inert filter material that does not chemically react with or adsorb volatilized medicinal compounds. The filter creates an inert environment for the vapor passage, allowing medicinal compounds to pass through without being retained, while still providing physical filtration of particulate matter through its structural properties.
Solution Approach 2:
The patent replaces chemical filtration mechanisms (adsorption) with a purely mechanical/physical filtration approach. The filter relies on physical barrier properties and pore structure to trap particulate matter, eliminating chemical interactions that would otherwise remove medicinal compounds from the vapor stream.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The inert filter effectively reduces the inhalation of particulate matter while preserving a majority of the desired medicinal compounds, allowing for safer and more hygienic use of medicinal vapors, particularly in group settings, by minimizing the loss of therapeutic volatilized oils and preventing cross-contamination.
Implementation Method 1
a filter comprised of a chemically inert material, wherein the filter is configured to cover a mouth-contacting surface of the mouthpiece and remove smoke particles or other particulate matter generated by the medicinal vaporizer
Data Source
AI summary
A system for filtering vaporized medicinal compounds includes a vaporizer configured to release one or more volatilized medicinal compounds in gaseous form, together with solid or semi-solid particulate byproducts, and one or more removable filters for efficiently removing at least a portion of the particulate byproducts while allowing passage of medicinally active volatilized compounds. The vaporizer includes a mouthpiece through which one or more volatilized medicinal compounds may be drawn. The filter is made of a chemically inert material (e.g., polypropylene or other polyolefin) and may be configured to detachably interface with an exposed surface of a vaporizer mouthpiece. The filter acts to remove solid or semi-solid particulate matter passing through the mouthpiece with minimal chemical and/or physical interference with volatilized medicinal compounds, which pass through the filter. The removable filter can also prevent cross-contamination by multiple users of the vaporizer.
