Description

Wearable laser phototherapy device

The invention relates to a wearable laser phototherapy device.

According to reports, in recent years, due to the improvement of public health concepts and the popularity of sports, more and more people may suffer from joint pain during exercise. Therefore, many auxiliary equipment are used to alleviate the problem of joint pain. One of the common methods to relieve knee pain is to use a low-energy laser light to stimulate muscle or joint tissue to repair and relieve pain. However, even if the low-energy wavelength of low-energy laser light irradiates human skin without causing harm, the light intensity of low-energy laser light is still beyond the range that human eyes can adapt to. In other words, the energy intensity per unit irradiation area of the laser is too large, making the laser light too bright for human eyes. If it shines directly into human eyes, it may cause damage to the eyes.

However, the existing laser phototherapy device is only equipped with a start switch to activate the laser. If it is accidentally detached during use, the trajectory of the laser light will be uncertain, and it may directly hit the human eye and cause eye damage. In addition, because the laser light used in some phototherapy treatments is invisible light, even if the user accidentally looks directly at the laser light, he or she will not be able to react in time, which may further cause more serious eye damage. In addition, laser light of the same wavelength can illuminate the body at the same depth, so it cannot effectively penetrate into the superficial, middle and deep layers of the human body for phototherapy at the same time. There are shortcomings that need to be improved urgently.

Therefore, it is necessary to provide a novel and progressive wearable laser phototherapy device to solve the above problems.

The main purpose of the present invention is to provide a wearable laser phototherapy device that can ensure that the wearable laser phototherapy device with safety protection function has no doubts about starting the phototherapy beam before positioning, so as to avoid direct damage to human eyes caused by the laser beam.

In order to achieve the above object, the present invention provides a wearable laser phototherapy device, which includes a housing, a start switch, a light-emitting module, a processing module and a proximity sensing module. The housing includes a light exit surface, and the light exit surface is provided with a light exit port. The start switch is arranged on the housing. The light-emitting module is disposed in the housing and faces the light exit surface, and is used to generate a phototherapy beam and emit the housing from the light exit port. The processing module is disposed in the housing and is electrically connected to the light-emitting module and the start switch. The proximity sensing module is disposed in the housing, faces the light emitting surface, and is electrically connected to the processing module. Wherein, when the startup switch is activated, the startup switch generates a startup signal to the processing module. When the processing module receives the startup signal, the processing module enters a standby mode; wherein, when the proximity When the proximity sensing module senses that a human body approaches the light emitting surface, the proximity sensing module generates a trigger signal and transmits it to the processing module; wherein, when the processing module receives the trigger signal in the standby mode, The processing module enters a light-emitting mode from the standby mode, and controls the light-emitting module to generate the phototherapy beam; wherein the phototherapy beam includes an output light power of 60 to 120 milliwatts (mW) and an output light wavelength of 600 to 808 nanometer (nm) beam.

Therefore, since the present invention has the proximity sensor module 5, when the proximity sensor module 5 senses that the human body is approaching the light emitting surface 11 and generates the trigger signal, it means that the light outlet 111 is close to the human body, for example Knees, elbows, ankles, etc., so that the light therapy beam generated by the light-emitting module 3 has no concern of directly hitting the user's eyes. When the proximity sensing module 5 is moved away from the human body, the proximity sensing module 5 does not sense the human body, the light-emitting module 3 stops generating the phototherapy beam and enters the standby mode, whereby the present invention can significantly reduce the risk of the phototherapy beam directly hitting the user's eyes.

Among them, the phototherapy beam includes a beam with an output light power of 60 to 120 milliwatts (mW) and an output light wavelength of 600 to 808 nanometers (nm).
