Abstract

The invention relates to a therapeutic device in the field of medicine, in particular to a narrow-spectrum light-emitting diode (LED) purple-light therapeutic apparatus. The narrow-spectrum LED purple-light therapeutic apparatus comprises a therapeutic head (1), a support (2) and a machine box (3), and is characterized in that the therapeutic head consists of a radiator (4), a semiconductor refrigeration chip (5), purple-light chips (6), a cup-shaped reflector (7) and a shell (8). By the refrigeration effect of the semiconductor refrigeration chip, the constant temperature of the purple-light chips is ensured, and a purple-light source which only produces a single wavelength of 308 or 365nm is fulfilled.

Description

Narrow spectrum LED purple light therapeutic instrument

Technical field

The present invention relates to the therapeutic device of medical domain, particularly a kind of narrow spectrum LED purple light therapeutic instrument.

Background technology

Medically use purple light chemotherapy (PUVA) treatment pigmented dermatosis, such as vitiligo, leukoplakia vulvae, psoriasis, scleroderma etc., extensively adopt, present purple light therapeutic instrument develops to violet light diode from mercury lamp, yet its spectral wavelength but comprises certain limit, such as UVA wave band 320～400nm, UVB wave band 275～320nm, well-known ultraviolet has injury to human body skin, even may be carcinogenic, wavelength is longer darker to skin penetration, destructive power to dermal tissue is larger, and the purple light that only has specific wavelength that really can treat pigmented dermatosis is only the most effective, such as the purple light treatment psoriasis of 308 nanometers, vitiligo etc. are the most effective, the purple light treatment lupus erythematosus of 365 nanometers, scleroderma is the most effective, and other wavelength does harm rather than good treatment.But the spectrum that violet light diode sends is shown in a figure among Fig. 3, the spectrum that has comprised 295～320 nm wide regions, in order to improve curative effect, avoid injury, spectrum is only desirable shown in the b figure among Fig. 3, according to the led lighting principle, determine that the factor of emission wavelength is except material, the most important thing is the energy of atom outer-shell electron, energy is higher, and electronics is shorter from the light wave that high level transits to low-lying level release when hole and electron recombination, the energy of outer-shell electron is determined by temperature, the energy of outer-shell electron is also constant when temperature constant, and the light wave that discharges during transition is also constant, thereby has guaranteed that diode sends the purple light of single wavelength.

Summary of the invention

Purpose of the present invention allows purple light therapeutic instrument send the narrow spectrum purple light of changeless 308 ± 2 nanometers or 365 ± 2 nanometers exactly, its difficulty is that the volume of violet light diode own is very little, the energy density of heating is very high, and area of dissipation is little, and thermal resistance is large, can't guarantee violet light diode constant temperature by air-cooled or water-cooled merely, the present invention utilizes semiconductor refrigeration chip, and the heat that violet light diode produces, conduction is to radiator, greatly reduce the thermal resistance of violet light diode, to guarantee violet light diode constant temperature.

The technical solution used in the present invention is: narrow spectrum LED purple light therapeutic instrument (Fig. 1), a kind of dermopathic instrumentations such as vitiligo, psoriasis, leukoplakia vulvae, scleroderma, lupus erythematosus for the treatment of, comprise treatment 1, support 2, cabinet 3, it is characterized in that described treatment 1(Fig. 2), by radiator 4, semiconductor refrigeration chip 5, purple light chip 6, cup type reflector 7, shell 8 forms.

Described radiator 4 can be air-cooled, water-cooled or natural cooling.

Described semiconductor refrigeration chip 5 huyashi-chuuka (cold chinese-style noodles) and purple light chip 6 are closely connected, and hot side and radiator 4 are closely connected, and with the thermometric device, press the refrigeration electric current that temperature requirement is regulated refrigerating chip.

The present invention compares with existing purple light therapeutic instrument, is the purple light of single 308 nanometers or 365 nanometers because it sends, so therapeutic effect is good, side effect is little.

Specific implementation method

Narrow spectrum LED purple light therapeutic instrument (Fig. 1) comprises treatment 1, support 2, cabinet 3, it is characterized in that described treatment head (Fig. 2), is by radiator 4, semiconductor refrigeration chip 5, purple light chip 6, cup type reflector 7, shell 8 forms, and the sink side for the treatment of 1 has direct current supply line and control line, through the hollow pipe of support 2, lead to cabinet 3.

Described radiator 4 can be air-cooled or water-cooled, also can use natural cooling for single purple light pipe hand-held treatment head.

Described semiconductor refrigeration chip 5 is selected the TEC1 type, and the purple light chip is selected the UV310-S-TO39F-A type, and refrigerating chip huyashi-chuuka (cold chinese-style noodles) and purple light chip are closely connected, and with the thermometric device, presses the refrigeration electric current that temperature requirement is regulated refrigerating chip, and hot side and radiator are closely connected.

In the described cabinet 3, comprise the power-supply controller of electric of the required power of alterating and direct current of complete machine, purple light chip, the temperature measure and control device of refrigerating chip, the irradiation time of purple light, intensity all have Single-chip Controlling, all lead to power line and the control line for the treatment of head, all lead to through the hollow pipe of support 2 and treat 1.
