International Classification:

B05B 5/001

US Classification:

239690, 2396901, 239692, 239704, 239708, 222390

Abstract:

A cartridge for a handheld electrohydrodynamic (EHD) spraying device and a spraying device incorporating the cartridge. The cartridge is disposable, and can contain therapeutic products. The device includes a wetted lead screw with a compliant seal, where the placement of the seal relative to the screw inhibits leakage during both cartridge use and storage. A frame disposed within the cartridge acts as a load-transferring mechanism for the weight of the cartridge to a handle of the spraying device.

Abstract:

A method for delivering an aerosol, especially an aromatic aerosol, comprising the steps of contacting a capillary wick, comprising an EHD comminution site, with a liquid source, whereby at least a portion of the liquid transports to the EHD comminution site; applying a voltage to the liquid within the capillary wick at a location spaced apart from the liquid source and proximate the EHD comminution site; and applying a ground reference at a location external to the EHD comminution site, wherein at least a portion of the liquid EHD comminutes to form a spray having a generally-consistent flowrate and a device therefor.

International Classification:

A61K009/46

US Classification:

424466000

Abstract:

The present invention provides a manufacturing process for quick dissolving products having active ingredients directed to agrochemical applications, such as plant applications and animal and animal health applications. Electrohydrodynamic (EHD) spraying is used to form a product form preferably comprised of fibers that contains a desired agrochemical compound formulated to quickly disintegrate on contact with a solvent such as water. The dispersed chemical is then provided as a sprayable solution. Because the product form contains little or no liquid, significant size and weight savings are gained, higher active ingredient loadings may be placed in a smaller amount of material, and manufacturing, packaging and transportation costs are thereby reduced without impacting user-friendliness. In addition, the EHD manufacturing method of the present invention also permits combining active ingredients previously not capable of effective use together in a single product. Small, low cost and potentially modular production operations may be used to practice the invention, thus enabling production facilities to be located close to markets, and product design specific to local or regional markets.

International Classification:

A01K 67/00

US Classification:

800003000, 800008000

Abstract:

A process is disclosed which utilizes charged material, preferably created with the use of electrohydrodynamic (EHD), or electric field effect technology (EFET), to apply pesticides, other therapeutic products, or cosmetics to non-animals. In particular, the instant invention relates to the application of certain active ingredients, solvents, spreading oils, colorants, preservatives, thickeners, carriers, or other compounds in a uniform manner so as to minimize dermal reactions, increase efficacy, reduce dosage, and improve ease of use, safety, and convenience.

Abstract:

A method and device are provided for providing sensory cues, signals, or indicators regarding the status of electrohydrodynamically spraying a material, including power-on status of an electrohydrodynamic spray device, active electrohydrodynamic spray status, and material status within the electrohydrodynamic spray device. In particular, audible, tactile, or intermittent visible signals indicate active electrohydrodynamic spraying, audible, tactile, or visible signals indicate power-on status of the electrohydrodynamic spray device, and sensory signals indicate the status of other operationally-related variables, including the rate of electrohydrodynamic spray, time increments, which may be correlated with electrohydrodynamic spray flowrates, and material supply levels.
