Description

Infrared electrotherapy module

technical field

The present application relates to an infrared electrotherapy module, in particular to an infrared electrotherapy module that can promote wound repair.

Background technique

It is known that when electrical current enters skin tissue, it increases the movement of neutrophils and macrophages and stimulates fibroblast proliferation, a process that promotes wound healing. Based on the above principles, an electrotherapy module has been designed, which can be used to promote wound healing, especially chronic wounds that are difficult to heal due to chronic diseases (eg, diabetes). The existing electrotherapy module includes a power supply apparatus and an electrotherapy patch, and the electrotherapy patch is electrically connected to the power supply apparatus. When using the electrotherapy module to treat the patient's wound, the electrotherapy patch is first attached to the skin near the wound, and then the power supply device supplies power to the electrotherapy patch, and the electrotherapy patch transmits electrical stimulation to the skin , thereby promoting the repair of skin wounds.

However, since the effective area of electrical stimulation therapy may only be limited to the vicinity of the muscle tissue receiving electrical stimulation, there is no significant effect on more distant tissues, and electrical stimulation must be applied to the wound when performing electrical stimulation therapy. The local blood circulation can be promoted only by the nearby muscles that can be electrically stimulated. Based on the above, it can be seen that the effect of electrical stimulation therapy on wound repair is limited, so that the effect of existing electrical therapy modules in promoting wound repair is still not significant enough.

Detailed ways

In order to fully understand the purpose, features and effects of the application, through the following specific embodiments, and in conjunction with the accompanying drawings, the application is described in detail as follows:

Embodiment 1 of the present application provides an infrared electrotherapy module 1 . Referring to FIGS. 1 and 2 , the infrared electrotherapy module 1 includes a housing 11 , a power supply 12 , an infrared circuit 13 , an electrotherapy circuit 14 , an infrared light source 15 and a pair of connecting portions 16 . The power supply 12 is disposed in the casing 11 and provides power to the infrared circuit 13 and the electrotherapy circuit 14 . The infrared circuit 13 is disposed in the casing 11 and drives the infrared light source 15 to emit infrared rays. The infrared light source 15 is disposed in the housing 22 and provides infrared rays with a wavelength of 2 to 25 μm. The electrotherapy circuit 14 is arranged in the housing 11 and provides a therapeutic current for applying to the skin, and the electrotherapy circuit 14 can be electrically connected to the electrotherapy patch (not shown in the figure) through the pair of connecting parts 16 . ).

In this embodiment 1, when the infrared electrotherapy module 1 is to be used to treat a patient, the infrared electrotherapy module 1 is connected to the electrotherapy patch through the pair of connecting parts 16, so that the electrotherapy circuit 14 An electrical current can be delivered to the electrotherapy patch. Next, the electrotherapy patch electrically connected with the infrared electrotherapy module 1 is attached to the skin near the patient's wound, and the infrared electrotherapy module 1 is activated, so that the infrared light source 15 emits infrared rays with a wavelength of 2 to 25 μm Irradiate the wound on the skin and the nearby skin, and the electrotherapy patch also electrically stimulates the skin near the wound of the patient. Through the above operation process, phototherapy and electrotherapy courses for promoting wound healing can be performed on the patient through the infrared electrotherapy module 1 .

Regarding the effect of infrared rays on promoting wound repair, it has been mentioned in the existing literature that infrared rays have the effect of promoting wound repair (Hsu, Y.H., et al., Far infrared promotes wound healing through activation of Notch1 signaling. J Mol Med (Berl ), 2017.95(11):p.1203-1213). It is also mentioned in other literature that infrared rays with a wavelength of 2 to 25 μm have a more excellent effect of promoting wound repair when irradiating the wound site on the skin (H, TOYOKAWA., et al., Promotive Effects of Far-Infrared Rayon Full-Thickness Skin Wound Healing in Rats.Exp Biol Med(Maywood).2003Jun;228(6):724-9;Hui-Wen Chiu.,et al.,Far-infraredpromotesburnwoundhealingbysuppressingNLRP3inflammasomecausedby enhanced autophagy. J Mol Med (Berl). 2016 Jul;94(7):809-19).

The infrared electrotherapy module 1 is based on the above-mentioned principle, in addition to providing electrical stimulation through the electrotherapy circuit 14 to promote wound repair, the infrared light source 15 also emits infrared rays to enhance the effect of wound repair. Therefore, compared with the existing electrotherapy module which only promotes wound repair through electrical stimulation, the infrared electrotherapy module 1 further improves the effect of promoting wound repair by combining electrical stimulation and infrared irradiation. Therefore, the infrared electrotherapy module 1 solves the problem that the effect of the existing electrotherapy module in promoting wound repair is still insufficient.

In addition, the existing electrotherapy patch is connected to a specific power supply device by wires, and then the electrical stimulation is delivered to the patient through the power supply device, and the power supply device is usually a device that is not easy to move. In this way, when a patient receives electrotherapy through the existing electrotherapy module, the treatment can only be carried out in a place with a specific power supply device. The patch is removed from the body and the treatment is suspended, all of which cause the patient to have limited mobility during the electrotherapy session.

The main difference is that the infrared electrotherapy module 4 The material and structure of the electrotherapy patch are different from the electrotherapy patch 38 of the infrared electrotherapy module 3 .

Since the main structure of the infrared electrotherapy module 4 is the same as that of the infrared electrotherapy module 3 in the third embodiment, only the cross-sectional structure of the electrotherapy patch is shown in FIG. 6 here. The electrotherapy patch includes a base material layer 481 , an infrared radiation layer 482 , a heating coil 483 , a conductive layer 484 , an electrode terminal 485 and a pair of electrode terminals 486 .
