According to an aspect, there is provided a treatment device for performing a treatment operation on or to a subject. The treatment device comprises: an optical diffuser arranged on the treatment device such that an outer surface of the optical diffuser is proximate to, or in contact with, skin of the subject when the treatment device is to be used to perform the treatment operation; and an imaging unit for obtaining one or more images using light passing through the optical diffuser into the treatment device; wherein the treatment device is further configured for providing one or more images to a processing unit for determination of whether the treatment device is in contact with the skin.

According to an aspect, there is provided an apparatus for use with a treatment device for providing feedback to a user on a treatment operation performed on a body part of a subject, wherein the treatment device is configured to apply light pulses to skin of the body part to perform the treatment operation, wherein a light pulse applied to the skin treats an area of the skin. The apparatus comprises a processing unit configured to receive a first measurement signal from a first sensor, the first measurement signal comprising information about positions and/or movements of the treatment device over time; for a light pulse previously applied by the treatment device to the body part during the treatment operation, process the first measurement signal to estimate a previous treatment position as a position of the treatment device relative to the body part when the light pulse was generated; for the previously applied light pulse and based on the estimated previous treatment position, estimate a previous treatment area for the light pulse corresponding to the area of skin of the body part that the light pulse was applied to when the treatment device was at the previous treatment position; process the first measurement signal to estimate a current position of the treatment device relative to the body part; based on the estimated current position of the treatment device, estimate a current treatment area corresponding to an area of skin that the treatment device would apply a light pulse to while in the current position; and generate a feedback control signal for a feedback unit, wherein the feedback control signal is configured to cause the feedback unit to generate feedback indicating whether the current treatment area corresponds, or substantially corresponds, to a previous treatment area.

The massage head comprises a massage head cover, a massage member, a cooling and heating component and a conductive quick-connecting component; wherein the massage head cover and the massage member are provided oppositely, the massage head cover and the massage member encircle an accommodating cavity for accommodating the cooling and heating component, and the conductive quick-connecting component is provided at the end of the massage head cover away from the massage member and electrically connected to the cooling and heating component; the massage head is detachably electrically connected to the massage gun body through the conductive quick-connecting component; the massage gun comprises a massage gun body, a grip handle, a reciprocating driving mechanism, a main circuit board, and a massage head.

A fascia tissue treatment device includes a bar member, at least one tissue treatment element supported by the bar member, and at least one treatment accessory removably connected to the bar member.

The present invention provides for devices and methods of treating wounds, including general wounds, gum disease and gingival tissues post scaling/root planning, using a diode laser which generates a beam of light having a wavelength in the visible portion of the electromagnetic spectrum (400 nm-700 nm). Further disclosed are devices and methods capable of stimulating tissue regeneration at the site of a wound.

Combined methods for treating a patient using time-varying magnetic field are described. The treatment methods combine various approaches for aesthetic treatment. The methods are focused on enhancing a visual appearance of the patient.

In one aspect, an example handheld device for providing a spectrochrome output includes (a) an enclosed chamber containing one or more substances; (b) a light source; (c) an electromagnetic coil; (d) one or more magnets; and (e) a housing, wherein the housing is configured to: (i) secure the enclosed chamber; (ii) secure the light source such that an output of the light source is substantially aligned to pass through the enclosed chamber in one or more directions; and (iii) secure the electromagnetic coil around the enclosed chamber such that an electromagnetic field is created in a substantially same direction of the output of the light source through the enclosed chamber.

A laser irradiation device for performing treatment on human skin includes a casing that includes a grip part and a barrel part; a laser oscillator that is accommodated in the casing and configured to generate a laser beam to be irradiated through the barrel part; a contact sensor unit that includes electrodes exposed at the end of the barrel part and a contact sensing unit configured to sense an electric current flowing through the electrodes; and a skin treatment unit that is detachably connected to the barrel part and is operated based on electric signals transmitted through the electrodes of the contact sensor unit.

A phototherapy system for treating a user can include an applicator, a controller, and a communication cable configured to couple the applicator and the controller. The applicator can include a light source, a thermal sensor, and a fan. The controller can be in communication with the applicator. The controller can be configured to receive a predetermined treatment regimen to be applied to the user via the applicator. A method for treating skin presenting psoriasis includes providing a phototherapy system. The user can select a skin type on the controller. The use can place the applicator adjacent to the skin presenting psoriasis, eczema, or vitiligo. The user can receive a light therapy treatment from the applicator, whereby the psoriasis, eczema, or vitiligo has been treated.

Provided is a skin care device including a head part brought into contact with skin of a user, a battery configured to supply power for operation of the head part, a body part having a fastening portion provided at one end to which the head part is fastened and provided with the battery therein, and a cap assembly detachably attached to one end of the body part and forming an accommodation space configured to accommodate the head part, wherein the cap assembly includes a sterilization module disposed to irradiate ultraviolet light toward the head part when the cap assembly accommodates the head part.
