The kit evaluates the patient's skin for penicillin sensitivity. The kit comprises a container, a multi-site skin test system, four preloaded syringes, and a tattoo-type label that is transferable onto the patient's skin. A multi-site skin test applicator is cooperatively engageable with four reservoirs in a fluid tray. The applicator pierces the patient's skin as trace amounts of the allergy test fluids are simultaneously administered. The tattoo-type label is transferable onto the skin of the patient and includes a QR Code. The QR Code includes machine-readable linkage to artificial intelligence for assisting a doctor in interpreting patient test results. The doctor reviews the artificial intelligence analysis and decides either to accept the analysis or modify it. The doctor may also decide to verify negative results with a subcutaneous skin test. The four syringes for the subcutaneous skin tests are preloaded with saline, Pre-Pen, Pen-G, and histamine.

A multiple test applicator has a first and second scratching barb in cooperative engagement with each other and a first and second reservoir in a fluid tray each filled with a first and second allergen. During allergen loading, the first allergen is loaded onto the first scratching barb as the second allergen is loaded onto the second scratching barb. Then, during allergen deposition the applicator is removed from the fluid tray and the first scratching barb moves laterally across the patient's skin as the second scratching barb moves laterally across the patient's skin toward the first scratching barb. The first scratching barb then scratches the epidermis at a first test site as a trace amount of the first allergen is deposited into a first site as the second scratching barb scratches a second site as a trace amount of the second allergen seeps into the second site.

Disclosed herein are devices (e.g., needles (e.g., hollow needles), hollow staples, articles, apparatuses, and systems), kits, and methods for treating skin and skin conditions, for example, by promoting skin tightening, such as by reducing skin laxity and reducing tissue area or volume.

Methods and systems are provided for assisting a user of a wearable biosignal monitoring device (2) in adjusting the device to achieve optimum fit and positioning. The biosignal monitoring devices considered use integrated bio sensors (5) to monitor the user’s physiological activity for various purposes such as tracking daily activity patterns, determining mood, and monitoring sleep stages, among others. It is determined either during device setup or during primary use of the device whether the current fit and positioning of the device (2) enable the bio sensors (5) to properly sense the physiological signals needed for the device to perform its primary function. The user is then informed either after initial device setup whether adjustments need to be made in order to optimize device function during primary use, or is informed after primary use whether adjustments need to be made in order to improve device function during future primary use.

Embodiments of an apparatus include a needle cartridge configured to attach to and interface with an actuating device. The needle cartridge includes a housing, a needle group assembly, and a fluid port. The housing forms a cavity and includes a first aperture and a second aperture opposite the first aperture. The needle group assembly includes a needle and a needle holder. The needle group assembly is configured to move in a reciprocating motion relative to the housing along an axis from the first aperture to the second aperture. During the reciprocating motion, the needle fully retracts into the cavity through the first aperture. The fluid port is integrated with the housing and includes a hollow projection forming a conduit and extending away from the housing. The fluid port includes a third aperture, wherein the fluid port is configured to interface with a fluid delivery system.

There is provided a skin-care balm comprising 15% to 45% (w/w) of two or more waxes, wherein a first wax has a melting point of 70° C. to 90° C. and a second wax has a melting point of 30° C. to 60° C., the balm further comprising 45% to 70% (w/w) of an emollient and a skin soothing agent. The skin-care balm can be applied to the skin in the perinasal area. There is also provided a combination product comprising a skin-care balm and a nasal spray product.

A combination product comprising a dispensing head (10, 10′) mounted on a top of a container (20, 20′) containing a formulation for nasal administration, and a solidified skin-care balm (50) for application around the nose contained in a balm holder element (30, 30″) located on a bottom (24) of the container (20).

Disclosed are a medicine injection tip that may smoothly insert and discharge a needle into and from skin, a hand piece, and a skin treatment device.

The present invention is directed to an applicator, configured to reversibly attach to a dispensing device, with at least one micropore and a kit for administration of a therapeutic agent. Methods of use of the applicator are also disclosed herein.

A scalp treatment applicator assembly includes a tube which contains a fluid scalp treatment. A cone is fluidly coupled to the tube and the cone is in fluid communication with an interior of the tube to receive the fluid scalp treatment. The cone tapers to point to penetrate the user's hair to apply the fluid scalp treatment to the user's scalp without disturbing the user's hair. A bulb is removably attachable to the tube and the bulb is comprised of a resiliently deformable material such that the bulb can be compressed by the user. The bulb is in fluid communication with an interior of the tube when the bulb is attached to the tube to urge the fluid scalp treatment outwardly through the cone when the bulb is compressed.
