Definitions

• the present invention relates to an apparatus for treating scars and of the type stated in the introduction of claim 1.
• the apparatus is characterized in that it is adapted to apply the electrodes a pulsatory current which starting from 0 ampere and with a pulse width of the magnitude of 1-2 m.sec, particularlyl .2 m.sec, grows to about 30 mA as the distance between the single current pulses of the pulse-"trains" are 2-4 m.sec.
• a pulsatory current which starting from 0 ampere and with a pulse width of the magnitude of 1-2 m.sec, particularlyl .2 m.sec, grows to about 30 mA as the distance between the single current pulses of the pulse-"trains" are 2-4 m.sec.
• corresponding current pulses are generated in and around the scar and a DC-current is generated in the subcutis which in addition to the current pulse stimulation also is warmed-up by the DC-effect.
• a dispersing medium suspended in a suctorial material layer such as viscose (cotton wool) .
• dispersing medium may be used ordinary, calcareous water. By the treatment it seems to be important to work with a good current dispersion between the electrodes and the skin, because hereby may be avoided uncontrol ⁇ lable current condition and over-heating of the skin which by way of example otherwise may occur if the electrodes cover the particular sensitive acupuncture points ("hot spots") .
• the apparatus according to the invention comprises a barrage diode being inserted between the current generator and one of the electrodes.
• the treating time is normally about 20 min. and the treating frequency is normally 2 days. Ordinary results are obtained after 4-6 treatments as the scar begins to tickle and the scar begins to suppurate particular ⁇ ly from the edge area thereof which lasts about 8 days. The visual effect moreover appears by the scar schrinking in the width and by the normally light and parchment-like skin of the scar again getting its normal blushing and suppleness.
• Fig. 1 shows an embodiment of an apparatus according to the invention.
• Fig. 2 shows a system diagram of the apparatus connected to an electronic "skin model”.
• Fig. 3 shows a measured voltage graph by the beginning of a treatment
• Fig. 4 shows a correspondingly measured voltage graph representing a longer period of time.
• the apparatus shown in Fig. 1 consists of a micro processor controlled current generator which via terminal conductors 4 are connected with plate shaped aluminium electrodes 6 positioned on the skin 8 at opposite sides of an elongated operation scar 10.
• the electrodes have to be adjusted in accordance with the actual treatment (the size and shape of the scar) and preferably be as big as
• the current generator has the following data: Short-circuit current (i.e. the current without loading betweenthe skin and electrodes): Max. 88 mA.
• Dispersion medium Calcareous water, i.e. hard water with the following specification: Hardness
• the "skin model" shown in Fig. 2 is adapted to connect directly between the terminal conductors 4, i.e. without dispersion medium.
• a cell has a voltage potential in. relation to the tissue fluid of 10-100 mV depending of the cell type.
• the potential comes into being partly by diffusion and osmosis and by actively pumping out of potassium ions (K+) to the tissue fluid through the cell membrane.
• K+ potassium ions
• C1- chloride ions
• ELF extreme ⁇ ly low frequency ⁇ 300 Hz
• This function will give a mechanism which will form resonance with a Q over 1 and transmit the field mechanically into the large DNA- oneculars of the cell nucleus.
