Abstract
An apparatus and method that is effective for the treatment of skin itch and skin rash is disclosed. The apparatus is contained within a body which can be easily manipulated with one hand, and which is powered by a self-contained battery. Also contained within the body is a heating means, controlled by a thermostat, a temperature selector if the heating means if intended to provide multiple temperatures, and means to warn the user when the desired temperature is reached. In addition the apparatus includes means to apply the heat in a cyclical manner, in which the heat is repeatedly applied and removed, with a cycle time and pulse width in which is controlled by user by means of a control located on the body heater and some other elements that can ensure only one substantially unique temperature is used. The method, which is related to the apparatus as its governing principle, includes the application of heat at a precise, controlled temperature, for a specific period of time, t the skin at the location of the itch or rash. The temperature used depends upon the nature of skin discomfort, but is generally inside the range between 46-62 DEG C. The temperature variation is generally controlled within +-0.5 DEG C. although it can be wider or narrower depends upon the nature of the itch treatment. In addition, the method includes a pulsating application of heat to the skin area, in which the heat is alternately applied and removed at a rate of approximately 1 second, with a total application time of between 10 and 30 seconds.
Description
The present invention relates to a kind of instrument of itching etc. with the thermal therapeutical dermatopathy relevant such as acne, skin with histamine, particularly a kind of to the specific thermal therapeutical instrument of above-mentioned illness.
The best antipruritic and treatment temperature that dermatopathy relevant with histamine such as acne, skin are itched etc. is 52 ℃～59 ℃.People once used scorching hot water heated skin antipruritic, because this method can not guarantee to use best antipruritic temperature, itched and ended incessantly sometimes, stopped though itch sometimes, but a few hours only antipruritic time, and side effect is arranged.Antipruritic and the therapeutic equipments of existing heat mostly is a thermostatic type, because the temperature that adopts skin to bear, generally be lower than 49 ℃, this method can not guarantee have the temperature of deterioration effect not to be used to itching, and this temperature range heats skin and crosses long-time skin heating makes above-mentioned skin disease suffer from the effect of increasing the weight of.When skin Mast cell was heated to 45 ℃, histamine etc. were enhanced from the exocytosis of Mast cell, and this enhanced results is that histamine etc. causes to itch and cause the swollen factor and increases at local concentration naturally, thereby aggravation is itched and be red and swollen.Cross long heating and can make deep skin tissue such as blood vessel equivalent damage, usually occur the red and swollen aggravation and the knock-on of itching etc. after the treatment and pay effect.Still there is not hot antipruritic therapeutic equipments now.
Purpose of the present invention is exactly that provide at above-mentioned weak point a kind of produces 52 ℃～59 ℃, antipruritic effective percentage height and be the instrument of the antipruritic and treatment of the skin heat of interrupted heating.
Technical solution of the present invention is: a kind of antipruritic and control the instrument of erythra such as acne with heat, comprise the power supply (battery or alternating current electrical network) that is located in the shell, it is characterized in that: be provided with heater at outer cover port, be provided with in the shell by this heater that makes that is in that this intravital thermal probe of generating heat, temperature select that beginning, temperature-adjusting circuit form and produce 52 ℃～59 ℃ and the thermostat galvanothermy device that intermittently heats.
Heater described in the technology of the present invention solution is a crystal triode, and thermal probe is a critesistor, and this thermal probe is arranged in the crystal triode.
Heater described in the technology of the present invention solution is the PTC exothermic material, and thermal probe is an electric contact thermometer, and this thermal probe is arranged in the PTC exothermic material.
The technology of the present invention solution can be provided with net at the port of shell, the inside of shell is provided with the push and pull system of being made up of the connecting rod that links to each other with heater, cam, tumbler, control circuit, when this push and pull system can make heater reach established temperature, automatically reach the net place, drop to established temperature when following, in the shell of withdrawing automatically.
The technology of the present invention solution can also be fixed on heater the port of shell handle.Shell is provided with display lamp, and this display lamp links to each other with temperature-adjusting circuit, in order to show that heater reaches selected 55 ℃ of temperature.
Heater described in the technology of the present invention solution can produce the temperature of 53 ℃, 55 ℃, 57 ℃, 59 ℃ (± 05 ℃ of excursion).
Though the present invention adopts the higher temperature of 52 ℃～59 ℃ or 53 ℃, 55 ℃, 57 ℃, 59 ℃, heater is interrupted heating, promptly heats for 1～3 second, at interval about 1 second at every turn.Like this, not only make skin can not produce severe pain, and, can in 1/4 second, be heated to skin surface (Mast cell place layer) temperature required rapidly, and it is antipruritic so that the Mast cell temporarily loses the ability that discharges that causing itches and cause the swollen factor to keep this temperature a period of time, simultaneously, deep skin tissue (being deeper than Dermis) still remains on safe temperature and is injury-free.Use the present invention intermittently to heat about 20 seconds, skin is itched stop immediately, antipruritic effective time the shortest is 24 hours, and the treatment back is without any side effects.Treat acne with the method, acne are itched and are stopped at once, and the acne redness was obviously dwindled in 6 hours.If in the treatment of acne initial phase, acne can be cured immediately.53 ℃ for treatment child and the adult face the best of itching, also best for the treatment acne.55 ℃ are into the person and the antipruritic optimum temperature of arm.57 ℃ is the antipruritic optimum temperature of adult's shank.59 ℃ is to be used for the treatment of to have the selection temperature of itching above the person skin of normal human skin thickness.
