Non-invasive skin treatment device using r.f. electrical current with a treatment settings determiner

The invention provides a non-invasive skin treatment device (100) comprising an r.f. treatment electrode (10); a return electrode (40); an r.f. generator (20) configured and arranged such that, during treatment, an r.f. treatment signal is applied between the r.f. treatment electrode (10) and the return electrode (40) for heating an inner region (15) of skin; an impedance measurement circuit (35) configured and arranged to measure, before treatment of the inner region, an initial skin impedance (Zo) between the r.f. treatment electrode (10) and the return electrode (40); and a treatment settings determiner (30) configured and arranged to determine, before treatment of the inner region (15), treatment settings associated with the r.f. treatment signal depending on the initial skin impedance (Zo) and on a dimension of the r.f. treatment electrode (10) in the contact plane, the treatment settings comprising at least one of a treatment duration (TD) associated with a desired treatment result, and an r.f. electrical parameter associated with the r.f. treatment signal. The skin treatment device (100) further comprises a controller (25) configured and arranged to consecutively activate the impedance measurement circuit (35) and the treatment settings determiner (30) before treatment of the inner region (15), configure the r.f. generator (20) to provide the r.f. treatment signal according to the treatment settings, and activate the r.f. generator (20) to apply the r.f. treatment signal to the inner region (15) for the treatment duration (TD). The invention is based on the insight obtained from multiple measurements made during the creation of microscopic thermal lesions in an inner region of skin by applying r.f. measurement and treatment signals. By analyzing the histological and heating results, a relationship was obtained between the initial impedance (Zo), the dimension of the r.f. treatment electrode (10), and the treatment settings required to obtain a particular skin treatment result. This relationship has been found to be relatively constant for different subjects, different treatment locations on the body and different skin moisture contents. The invention makes it possible to preset or predetermine, i.e. in advance, the treatment duration (TD) and/or the r.f. electrical parameters associated with the r.f. treatment signal accurately enough to avoid undesired skin damage during the treatment. The device can be simpler, as it is no longer essential to continuously monitor the impedance during treatment to determine the onset of undesired skin damage, such as ablation, which is the safety feature known from conventional devices.

Heat treatment setting method for high-strength elastic material coil spring

The invention relates to the field of aero-engines, in particular to a heat treatment setting method for a high-strength elastic material coil spring. The coil spring part requires a large deformation space, the intervals between circles of the coil spring part are not equal, the intervals of the inner circles are large while the intervals of the outer circles are small, the deformation rule is violated, and the outer diameter is limited. A ring type heat treatment setting clamp is adopted, the coil spring part is screwed and put into the setting clamp, and pins of different sizes are nailed into the intervals between the circles, thereby ensuring that the intervals of the inner circles are large while the intervals of the outer circles are small for heat treatment setting processing, and ensuring that the intervals between the circles are different. A vacuum furnace is adopted, heat preservation is carried out at the temperature of 800+/-10 DEG C for 60-75 min, and then carried out again for 120-135 min after the furnace is cooled to be 700+/-10 DEG C, and argon is injected for cooling. Thus, the problems of deformation and non-uniform intervals after the coil spring is formed are solved through adopting the heat treatment setting; it is ensured that the sizes of the intervals of the inner circles and the outer circles of the coil spring meet the design requirements; and the size stability is also ensured.
