  • Patent number: 12257129
    Abstract: A therapy device having transdermal and/or topical delivery features to treat myofascial and/or musculoskeletal tissue imbalances and/or treat inflammation. The therapy device is comprised of a soft tissue mobilizing device having a front surface, and a back surface having transdermal delivery features. The back surface includes a therapeutic substance disposed thereon and an adhesive to adhere the device directly to the soft tissue area of a user's body where muscle tension, aches and pain are present. The device when applied decompresses the soft tissue area being treated. The front surface includes a gripping mechanism to allow the user to grip the mechanism to manually lift and shift the soft tissue area being treated. The transdermal delivery features of the device and the manual lifting and shifting of the user's soft tissue reduces the time period for normalizing the myofascial and/or musculoskeletal tissue area being treated.

  • Patent number: 12201733
    Abstract: A system for the transdermal delivery of drugs, vitamins, or micronutrients over a time interval of up to one month. The transdermal delivery system employs a plurality of varying diameter bioactive glass capsules configured to react with water in the bloodstream to break down and release a contained dose of a drug, vitamin, or other micronutrients. The bioactive glass capsules are microscopic and able to be absorbed through the skin. An adhesive bandage is adhered to the skin via an adhesive layer. A concealed membrane is positioned centrally on an inner surface of the adhesive bandage and separated by a barrier layer. The bioactive glass capsules are housed within the concealed membrane until the patch is placed on the skin allowing them to absorb through the skin to deliver up to a month's dose of the drug, vitamin, or other micronutrients into the bloodstream.

  • Patent number: 11517009
    Abstract: An apparatus and method deliver fluid treatments to a targeted plant. The apparatus comprises a two-piece protective shell joined on one side by a spring-hinge. When the two piece outer protective shell is open, a fluid treatment is applied to a liquid retaining material within the protective shell. A portion of a targeted plant is placed within the open outer protective shell. The two piece outer protective shell is then closed, creating a sealed containment environment that is immediately protected from environmental disturbance, prevents distribution of fluid treatment to non-treated plant materials, and will retain, store, and prevent leakage of the fluid treatment. The closed outer protective shell also clasps the plant portion, forcing contact of the target plant portion with fluid treatment residing on and within the liquid retaining material. The apparatus remains attached to the targeted plant while the fluid treatment is absorbed through systemic plant processes.

  • Patent number: 11241339
    Abstract: A binder layer for a laminated wound dressing is brought into contact with a sheet coated with a pattern-coated adhesive sheet. As the binder layer is in contact with the pattern-coated adhesive sheet, a series of closed-loop cuts are made in the binder layer. The closed-loop cuts are made in such a way that the material enclosed by each closed loop is substantially physically separated from the remainder of the binder layer. Then the binder layer is moved away from the pattern-coated adhesive sheet, so that the binder layer and the pattern-coated adhesive sheet are no longer in contact. When the binder layer and the pattern-coated adhesive sheet are moved apart, the material enclosed in the closed-loop cuts—i.e., the cut waste fragments—are retained on the pattern-coated adhesive sheet, ensuring that the binder layer includes a series of cleared perforations.

  • Patent number: 11083690
    Abstract: Enteric elastomers and related methods are generally provided. In some embodiments, the enteric elastomer is a polymer composite. Certain embodiments comprise a polymer composite in which hydrogen bonds within two carboxyl group-containing polymers cross-link the polymer networks into an elastic and pH-responsive polymer composite. Advantageously, this polymer composite has the capacity of being stable and elastic in an acidic environment such as that of the stomach but can be dissolved in a neutral pH environment such as that of the small and large intestines. In some embodiments, the polymer composites described herein comprise a mixture of two or more polymers with carboxyl functionality such that the two or more polymers form hydrogen bonds. In certain embodiments, the polymer composite has both enteric and elastic properties.
