Description

Technical Field

[0001] This invention relates to a massage chair device; more specifically, this invention relates to a massage chair device with infrared light emission function. Prior Technology

[0002] Photobiomodulation (PBM) is a process in which cells are stimulated by light sources of specific wavelengths, inducing physiological responses. Infrared light, with wavelengths ranging from 700 to 1000 nanometers, has attracted significant attention due to its high penetrability to biological tissues and its mitochondrial activation properties. Cytochrome c oxidase (CCO) in mitochondria acts as a photoreceptor for infrared light, serving as a terminal protease complex in the electron transport chain. CCO contains heme and two copper centers (CuA and CuB), exhibiting four distinct absorption peaks: 620 nm for reduced CuA, 820 nm for oxidized CuA, 680 nm for oxidized CuB, and 760 nm for reduced CuB. Upon absorbing infrared light, CCO promotes the electron transport chain and generates additional energy to produce DNA, RNA, and proteins, thereby activating cells, repairing damaged cells, and eliminating excess free radicals. For metabolic diseases such as diabetes, activating mitochondria can reduce insulin resistance and enhance blood glucose management. Therefore, photobiological regulation has diverse disease prevention and treatment effects, and has superior application value in health care.

[0003] Existing massage chairs typically emit far-infrared light, meaning infrared light with a wavelength of 15 micrometers or longer. While far-infrared light can promote blood circulation and raise body temperature, it does not possess mitochondrial activation properties. Therefore, existing massage chairs cannot provide photobiological regulatory effects. In view of this, there is still a need for a massage chair device with infrared light emission capabilities that can provide photobiological regulatory effects. Summary of the Invention

[0042] [2.] [Example]

[0043] [2.1.] [Preparation of Infrared Fluorescent Materials]

[0044] [Example 1]

[0045] 0.1581 g of alumina (Al₂O₃), 0.2026 g of indium oxide (In₂O₃), 0.6306 g of gallium oxide (Ga₂O₃), and 0.0087 g of chromium oxide (Cr₂O₃) were weighed and ground in a boron nitride mortar for 30 minutes to obtain a homogeneous mixture. Next, the mixture was placed in a small crucible, and the crucible was placed in a square furnace. The temperature was increased to 1550°C at a heating rate of 5°C / min under normal atmospheric conditions, and sintered at 1550°C for 5 hours. Afterward, the sintered material was removed and allowed to cool naturally to room temperature to obtain an infrared fluorescent material represented by the formula Ga₁.18(Al₀.₆₈In₀.₃₂)₀.₈O₃:₀.₀₂Cr₃⁺ (represented as "GAIO" in Figure 3).

[0046] [Example 2]

[0047] 0.1895 g of alumina (Al₂O₃), 0.8011 g of gallium oxide (Ga₂O₃), and 0.0094 g of chromium oxide (Cr₂O₃) were weighed and ground in a boron nitride mortar for 30 minutes to obtain a homogeneous mixture. Next, the mixture was placed in a small crucible, which was then placed in a square furnace and heated to 1550°C at a heating rate of 5°C / min under normal atmospheric conditions, and sintered at 1550°C for 5 hours. Afterward, the sintered material was removed and allowed to cool naturally to room temperature to obtain an infrared fluorescent material represented by the formula Ga₁.38Al₀.₆O₃:₀.₀₂Cr₃⁺ (represented as "GAO" in Figure 3).

[0048] [2.2.] [Fabrication of the first infrared light emitting unit]

[0049] First, a blue light-emitting diode (with a wavelength range of 450 nm to 480 nm and a peak at 460 nm) was placed on a carrier, and the first and second electrical connectors were connected as shown in Figure 2. Next, the infrared fluorescent materials of Examples 1 and 2 were mixed with liquid silicone resin at a weight ratio of 2:1 to prepare a colloidal mixture with a total weight of 1.5 grams. The colloidal mixture was then placed in a vacuum degassing mixer for mixing and degassing. Subsequently, the degassed colloidal mixture was placed in a dispensing machine and dispensed onto the blue light-emitting diode. Finally, the blue light-emitting diode covered with the colloidal mixture was placed in an oven and baked at 120°C for 8 hours to harden the colloidal mixture, resulting in the first infrared light emitting unit of Examples 1 and 2.

[0050] The first infrared light emitting units of Examples 1 and 2 were placed on the stage of a spectrometer (instrument model: FluoroMax-3, manufactured by HORIBA) and powered on to measure the emission spectrum. The results are shown in Figure 3, where Example 1 is indicated by "GAIO" and Example 2 by "GAO". In addition, Figure 3 also shows the absorption spectrum of cytochrome c oxidase (CCO).

[0051] As shown in Figure 3, the first infrared light emitting unit (GAIO and GAO) has a broad spectral emission spectrum. When compared with the absorption spectrum of cytochrome c oxidase (CCO), it can be confirmed that the near-infrared light emitted by the first infrared light emitting unit effectively covers the absorption spectrum of cytochrome c oxidase (CCO). Therefore, it can be confirmed that by placing this first infrared light emitting unit on the massage chair body of the massage chair device of the present invention, photobiological regulation function can be provided, offering the user the effect of mitochondrial activation.
