The present invention relates to a cosmetic process for a keratin substance such as the skin or the lips, comprising the steps of: applying onto the keratin substance at least one composition comprising at least one coloring agent; and applying onto the keratin substance, to which the composition has been applied, a microneedle sheet comprising a substrate sheet and a plurality of microneedles on the substrate sheet such that the microneedles are capable of penetrating into the keratin substance. According to the present invention, microneedles can penetrate into a keratin substance to provide the keratin substance with long lasting and uniform color effects.

An injector guard and related method of use may be used for micropigmentation and other similar procedures. The guard may attach to a removable or disposable component, such as an ink cartridge, or may connect to a reusable device, such as a tattoo gun. The guard may be also unitary with the ink cartridge, needle, or micropigmentation device. It may be disposable or may be reusable. It may include a leg which may be used to aid in controlling the position of the micropigmentation tool as well as the depth of penetration of the needle into the dermis, as well as, optionally, the angle of the instrument. The guard may also include a coupling body, which may attach to an ink cartridge or other device or component by a press-fit, snap-fit, friction fit, threading, or other means.

A container (200) for containing a coupling medium for transdermal delivery of a medicament and a transducer unit (100) for use with the container (200) are disclosed. The transducer unit (100) has a transducer (108) with an output face (110), and the container comprises a chamber (214) for receiving the coupling medium and a contact surface (212) for contacting the output face (110) of the transducer (108). The container (200) is attachable to the transducer unit (100) and is arranged such that, upon attachment of the container (200) to the transducer unit (100), an acoustic coupling for ultrasound transmission is formed between the output face (110) of the transducer (108) and the contact surface (212).

The invention relates to a dispensing system for use in cryogenic skin treatment that is capable of targeted delivery of a cryogen at a high rate, thereby achieving rapid freezing of targeted skin tissue. The dispensing system of the present invention uses a cryogen that contains dimethyl ether and is designed to deliver the cryogen in an accurate and very effective manner.

A graphene nano-steam generator and a beauty instrument are provided. The graphene nano-steam generator includes a coarse steam channel, a nano-steam channel and a high-voltage power supply device. The coarse steam channel is connected to a coarse steam manufacturing device and the nano-steam channel. The coarse steam channel is provided with a steam sieving device, and an end of the coarse steam channel is provided with a first electrode and a second electrode. The high-voltage power supply device is coupled to the first electrode and the second electrode. The high-voltage power supply device supplies high-voltage electricity to the first electrode and the second electrode, and forms a high-voltage arc discharge between the first electrode and the second electrode, thus the coarse steam molecular group flowing through is ionized by the high-voltage arc to generate a large amount of active nano-scale steam to be flowed out from the nano-steam channel.

Systems, methods and devices for administering medication are disclosed. One or more embodiments of a medication delivery device may include a syringe, a needle, a guiding element, and a volume limiter for limiting the amount of medication that can be drawn from a vial. At least one method for administering medication using a medication delivery device, may include: inserting a vial into a guiding element, drawing back on a plunger, removing the guiding element and the vial from a needle to expose the needle, inserting the needle into a patient, depressing the plunger to inject the medication into the patient, and withdrawing the medication delivery device from the patient.

A face engaging device such as a nozzle, facemask, etc., may include a housing including a fluid channel extending through the housing to an opening configured to be placed in fluid communication with the mouth of a user. The housing may include a first surface configured to be placed in contact with the skin of the user and a second surface exposed to the fluid channel. The face engaging device may also include a thermal actuator supported by the housing and including a first heat transfer surface position on the first surface, where the first heat transfer surface is configured to apply a thermal profile to the skin of the user when the opening is placed in fluid communication with the mouth of the user.

A pressure injuries therapeutic support surface is illustrated. The surface comprises an integrated system designed for a concurrent physical and psychoneuroimmunological approach over a user, wherein the system comprises one or a plurality of independent fluid-filled main chambers, made of waterproof, flexible, extendable, and elastic material and at least two accessory chambers connected to each main chamber with at least with two free-flow conduits. The system is managed through a powered mechatronic array with its own hardware and software based on microcontrollers for the simultaneous operation of specific multidisciplinary devices.

An improved device delivers a fluid medicament to the subcutaneous tissue of a user. The device is better suited for patients with Parkinson's Disease and other central nervous system disorders, than conventional infusion devices. The device can include a reusable part including a drive component (e.g., motor) and control electronics and a disposable part including a medicament reservoir. Medicament can be evacuated from the medicament reservoir by a plunger assembly that includes a plunger attached to a lead screw that is rotated by a nut, all within the disposable part. The device can be fluidically coupled with the tissue via a flexible cannula. Various embodiments relate to an improved cannula insertion mechanism that delivers the cannula under a force applied by a spring. Various embodiments relate to improved filling of the device, for example, using a vial adapter and an automated filling station.

A device is described for delivering a therapeutic vibration to a body. The device may include at least two motors in a housing with unbalanced masses coupled to their axles, such that vibration of the masses causes the two motors and housing to vibrate at a beat frequency 80. The motors and housing may be coupled to the body via a platform which places the motors and housings at or near a resonant structure in the body, creating a coupled oscillation between the platform and the body. The vibration may be based on the input signal, such that the system applies the vibration based on the input signal to the user, wherein the signal may be an audio or video signal. The system may be configured to measure and manipulate the flow of cerebral spinal fluid.
