Description

Antipruritic and control the instrument of erythra such as acne with heat

This utility model relates to a kind of instrument of itching etc. with the thermal therapeutical dermatopathy relevant with histamine such as acne, skin, and is 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 the temperature of itching on the best, 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.

The purpose of this utility model 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 utility model 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 this utility model technical solution is a crystal triode, and thermal probe is a critesistor, and this thermal probe is arranged in the crystal triode.

Heater described in this utility model technical 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.

This utility model technical 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.

This utility model technical 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 this utility model technical solution can produce the temperature of 53 ℃, 55 ℃, 57 ℃, 59 ℃ (± 0.5 ℃ of excursion).

Though this utility model 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 this utility model 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.
