Description

Wearable laser phototherapy device with safety protection function

A laser phototherapy device with safety protection function, especially a wearable laser phototherapy device with safety protection function.

Knee pain is a common problem for most people in modern society. With the popularity of sports, more and more people may use their knees improperly during sports, causing knee pain. At the same time, as the number of obese people in society increases, many adults suffering from arthritis, rheumatoid arthritis (RA) or fibromyalgia also suffer from knee pain.

Currently, one of the ways to relieve knee pain is to use photobiomodulation therapy, which uses low-energy laser light to stimulate muscle or joint tissue to repair and relieve pain. When the above-mentioned photobiomodulation therapy is applied to the knees of people with knee pain, it can help people with knee pain 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.

The above situation is even more dangerous for users with knee pain, because when a user with knee pain adjusts the laser light to illuminate the knee, the user may accidentally touch the start switch during the adjustment process and activate the laser light, causing the laser light to be activated before adjustment. Before reaching the appropriate position, it shines into the user's eyes looking at the knees.

In view of the above problems, the present invention provides a wearable laser phototherapy device with safety protection function, which can ensure that the wearable laser phototherapy device with safety protection function starts the phototherapy beam without any doubt before positioning.

The wearable laser phototherapy device with safety protection function includes: A housing including a light-emitting surface; wherein, the light-emitting surface is provided with a light-emitting port; A start switch is provided on the housing; A light-emitting module is disposed in the housing and faces the light exit surface, and is used to generate a phototherapy beam; wherein the phototherapy beam emits the housing from the light exit port; A processing module is provided in the housing and is electrically connected to the light-emitting module and the start switch; A proximity sensing module is disposed in the housing and faces the light emitting surface, and is electrically connected to the processing module; Wherein, when the activation switch is activated, the activation switch generates a activation signal to the processing module; Wherein, when the proximity sensing module senses that a human body approaches the light emitting surface, the proximity sensing module generates a trigger signal, and the proximity sensing module transmits the trigger signal to the processing module; Wherein, when the processing module receives the start signal, the processing module enters a standby mode, and when the processing module enters the standby mode and receives the trigger signal, the processing module starts from The standby mode enters a light-emitting mode and controls the light-emitting module to generate the phototherapy beam.

When the present invention is fixed on a user's knee, the light-emitting module can generate the phototherapy beam on the user's knee without any doubt. The proximity sensing module of the present invention is a safety mechanism. When the proximity sensing module senses that the human body is approaching the light emitting surface and generates the trigger signal, it means that the light emitting port will be close to the human body, such as the user's knees. Therefore, the phototherapy beam generated by the light emitting module has no Directly into the user's eyes. That is to say, the processing module confirms that the light-emitting module is close to the user's knee through the proximity sensing module before generating the phototherapy beam through the light-emitting module. Thereby, the present invention can significantly reduce the risk of the phototherapy beam directly hitting the user's eyes.

The invention is a wearable laser phototherapy device with safety protection function. In a first embodiment, the wearable laser phototherapy device with safety protection function includes a housing, a control circuit board, a light-emitting circuit board and a battery.

Referring to FIGS. 1 and 2 , a start switch 20 is provided on the housing 100 . The housing 100 includes a surface 110 and a light-emitting surface 120. The light-emitting surface 120 is provided with a light-emitting port 121, and the light-emitting port 121 is provided with a light-transmitting cover 122.

Referring to FIGS. 3 to 5 , the control circuit board 200 , the light-emitting circuit board 300 and the battery 50 are disposed in the housing 100 , that is, between the surface 110 and the light-emitting surface 120 .

Further, the start switch 20 includes a push cover 21 and a key switch 22. The push cover 21 is provided on the surface 110 of the housing 100, and the key switch 22 is provided on the control circuit board 200. The key switch 22 is electrically connected to the processing module 10 . The control circuit board 200 is provided with the key switch 22 and a processing module 10, and the light-emitting circuit board 300 is provided with a light-emitting module 30 and a proximity sensing module 40 respectively. The light-emitting module 30 and the proximity sensing module 40 on the light-emitting circuit board 300 face the light-emitting surface 120 of the housing 100 respectively. The battery 50 is disposed between the control circuit board 200 and the light-emitting circuit board 300, and the battery 50 is electrically connected to the processing module 10 and the light-emitting module 30 to provide power.

The processing module 10 is further electrically connected to the activation switch 20 , the light emitting module 30 and the proximity sensing module 40 respectively. When the start switch 20 is activated, that is, when the press cover 21 and the key switch 22 are pressed, the key switch 22 in the start switch 20 generates a start signal and transmits the start signal to the processing module. Group 10. When the processing module 10 receives the startup signal, it is powered on and enters a standby mode.

When the proximity sensing module 40 senses that a human body approaches the light emitting surface 120 , the proximity sensing module 40 generates a trigger signal, and the proximity sensing module 40 transmits the trigger signal to the processing module 10 . When the processing module 10 enters the standby mode and the processing module 10 receives the trigger signal transmitted by the proximity sensing module 40, the processing module 10 enters a light-emitting mode from the standby mode, and The processing module 10 controls the light-emitting module 30 to generate a phototherapy beam. The phototherapy beam generated by the light-emitting module 30 will emit from the light outlet 121 through the light-transmitting cover 122 and out of the light-emitting surface 120 . Moreover, because the light-emitting circuit board 300 is closely attached to the light-emitting surface 120, the phototherapy beam can reduce the distance from the light-emitting circuit board 300 to the light outlet 121 to emit the light-emitting surface 120, thereby reducing light loss. In addition, the light-transmitting cover 122 provided between the light-emitting module 30 of the light-emitting circuit board 300 and the light outlet 121 of the light outlet 120 can protect the light-emitting module 30 in the light outlet 121 from dust, etc. Contamination from foreign objects.

In this embodiment, the light-emitting surface 120 of the housing 100 is an insulator. The proximity sensing module 40 is a capacitive sensor and includes a sensing electrode. Furthermore, the light-emitting surface 120 is a dielectric, that is, an insulator that can be electrically polarized. In addition, since the proximity sensing module 40 is in close contact with the light-emitting surface 120 along with the light-emitting circuit board 300 , the sensing electrode is also in close contact with the light-emitting surface 120 . When the human body touches the position of the light-emitting surface 120 of the housing 100 corresponding to the sensing electrode, the capacitive sensor will generate the trigger signal and send the trigger signal to the processing module 10 .

In another embodiment, the proximity sensing module 40 is a resistive sensor. When the light-emitting surface 120 is touched by a user and deformed, the resistive sensor generates the trigger signal and sends the trigger signal to the processing module 10 .

In yet another embodiment, the proximity sensing module 40 is an optical sensor. The optical sensor generates a sensing signal and emits the sensing signal through the transparent cover 122 for sensing the human body. When the human body approaches the light emitting surface 120 , the optical sensor generates a distance signal and transmits the distance signal to the processing module 10 . In addition, the processing module 10 has a distance threshold. When the processing module 10 determines that the distance signal is less than or equal to the distance threshold, the processing module 10 determines that the trigger signal generated by the proximity sensing module 40 is received. When the processing module 10 determines that the distance signal is greater than the distance threshold, the processing module 10 determines that the trigger signal generated by the proximity sensing module 40 has not been received.

Furthermore, the activation switch 20 includes a backlight source 23 . The backlight source 23 is disposed on the control circuit board 200 and faces the surface 110 of the pressing cover 21 facing the housing 100 . When the processing module 10 enters the standby mode, the processing module 10 controls the backlight source 23 of the activation switch 20 to generate a first light signal. When the processing module 10 enters the lighting mode, the processing module 10 controls the backlight source 23 of the activation switch 20 to generate a second light signal. Furthermore, the first light signal and the second light signal have different colors or flashing frequencies.

In FIG. 3 , the backlight source 23 includes four light-emitting diodes (LEDs). When the processing module 10 enters the standby mode, the processing module 10 controls the LED light of the backlight source 23 to generate a green light. When the processing module 10 enters the lighting mode, the processing module 10 controls the LED light of the backlight source 23 to generate blue light. That is to say, the first light signal is a green light, and the second light signal is a blue light.

Please also refer to FIG. 5 . The proximity sensing module 40 on the light-emitting circuit board 300 further includes a first sensor 41 and a second sensor 42 . The first sensor 41 and the second sensor 42 are respectively disposed on opposite sides of the light-emitting circuit board 300 and face the light-emitting surface 120 . When the first sensor 41 senses that the human body is approaching the light-emitting surface 120 , the first sensor 41 generates a first trigger signal and transmits the first trigger signal to the processing module 10 . When the second sensor 42 senses that the human body is close to the light emitting surface 120 , the second sensor 42 generates a second trigger signal and transmits the second trigger signal to the processing module 10 . When the processing module 10 enters the standby mode and the processing module 10 receives the first trigger signal and the second trigger signal at the same time, the processing module 10 determines that the proximity sensing mode has been received. The trigger signal generated by the group 40 corresponds to entering the light-emitting mode so that the light-emitting module 30 generates the phototherapy beam. When the processing module 10 enters the standby mode, but the processing module 10 does not receive the first trigger signal and the second trigger signal at the same time, for example, it only receives the first trigger signal but not the second trigger signal. When the second trigger signal is generated, the processing module 10 stays in the standby mode.

After the processing module 10 enters the light-emitting mode, the processing module 10 further determines whether at least one of the first trigger signal or the second trigger signal is received. When the processing module 10 determines that at least one of the first trigger signal or the second trigger signal is received, the processing module 10 remains in the light-emitting mode. When the processing module 10 determines that the first trigger signal and the second trigger signal have not been received, the processing module 10 enters the standby mode from the lighting mode, and in this way the processing module 10 will control the backlight source accordingly. The LED light of 23 switches from producing a blue light to producing a green light again.

After the processing module 10 enters the light-emitting mode, when the processing module 10 determines that at least one of the first trigger signal or the second trigger signal is received, for example, when only the first trigger signal is received, the processing The module 10 determines that the light outlet 121 has not been significantly moved. Since the light outlet 121 has not moved significantly, there is no concern that the phototherapy beam will hit the user's eyes. Therefore, the processing module 10 continues to control the light-emitting module 30 to generate the phototherapy beam.

The light emitting module 30 further includes at least one visible light unit 31 and at least one non-visible light unit 32 . As shown in FIG. 4 , the light emitting module 30 includes two visible light units 31 and five non-visible light units 32 . When the processing module 10 controls the light-emitting module 30 to generate the phototherapy beam, the at least one non-visible light unit 32 generates a laser beam, and the laser beam has the wavelength of non-visible light, and the at least one visible light unit 31 generates A colored light beam, and the colored light beam has a wavelength of visible light. The colored light beam is a scattered light, and the scattered light can form a huge light spot at the irradiation location. The visible light units 31 are LED lamps, and the non-visible light units 32 are laser diodes (LDs).

Under the light-emitting mode, the processing module 10 controls the laser beam generated by the light-emitting module 30 to be a continuous wave or a pulse wave. The duty cycle of the pulse wave is 50%. Under the lighting mode, the processing module 10 is also provided with a timing function and has a working time threshold. When the processing module 10 enters the light-emitting mode, the processing module 10 starts counting a working time. The processing module 10 further determines whether the working time is greater than or equal to the working time threshold. When the processing module 10 determines that the working time is greater than or equal to the working time threshold, the processing module 10 automatically stops generating the laser beam and shuts down. When the processing module 10 determines that the working time is less than the working time threshold, the processing module 10 continues to generate the laser beam. When the processing module 10 is shut down, the processing module 10 needs to receive the startup signal again before it can be turned on and enter the standby mode. In this embodiment, the working time threshold is 10 minutes.

Further, the working time threshold defines a certain timed course of phototherapy, such as a 10-minute timed course. Assuming that the user inadvertently interrupts the timed course of phototherapy under the light-emitting mode, the user may have different expectations for the present invention. For example, when the present invention fits the user's knee for phototherapy, but the proximity sensing module 40 of the present invention moves away from the knee due to the movement of the user's knee, the user may have different opinions about the present invention. expect. One kind of expectation is to hope that the timed course of phototherapy can be restarted to completely execute the timed course of phototherapy. Another kind of expectation is to hope that the timed course of phototherapy can continue the progress before the interruption to completely execute the timed course of phototherapy. In other words, the user may have different perceptions and expectations regarding the completeness of the timed course of light therapy. In the following two embodiments, the present invention will address the above different expectations.

In one embodiment, the processing module 10 enters the standby mode because it determines that the first trigger signal and the second trigger signal have not been received, and the processing module 10 directly resets the timing of the working time. When the processing module 10 receives the trigger signal transmitted by the proximity sensing module 40 and returns to the light-emitting mode, the processing module 10 will restart the timing of the working time to restart the execution of the phototherapy. Scheduled itinerary.

In another embodiment, the processing module 10 enters the standby mode because it determines that the first trigger signal and the second trigger signal have not been received, and the processing module 10 suspends the timing of the working time. When the processing module 10 receives the trigger signal transmitted by the proximity sensing module 40 and returns to the light-emitting mode, the processing module 10 stops pausing the timing of the working time and allows the working time to continue timing. In other words, when the processing module 10 pauses the timing of the working time, the progress of the timing process is also paused. When the processing module 10 stops timing the working time, the progress of the timing stroke will be continued so that the present invention can continue to perform phototherapy on the user.

In addition, the non-visible light units 32 are collectively arranged in the center of the light-emitting circuit board 300, and the two visible light units 31 are respectively arranged at both ends of the non-visible light units 32, so the color light beams generated by the visible light units 31 The scattered light path will cover all angles of the laser beam generated by the non-visible light units 32 . In other words, the huge light spot formed by the irradiation place of the visible light units 31 will cover the irradiation place of the laser beam generated by the non-visible light units 32 . Therefore, even if the user cannot see the laser beam, the user can still see the huge light spot irradiated by the visible light units 31 and know the range irradiated by the laser beam, and thereby prevent mistaking the laser beam. .

The wavelength of light visible to human eyes falls approximately between 360 nanometer (nm) and 830 nm. In this embodiment, the light wavelength of the laser beam generated by the light-emitting module 30 is between 600 nm and 940 nm. In other words, the wavelength range between 830 nm and 940 nm belongs to the wavelength of infrared rays and belongs to non-visible light. Therefore, in the present invention, it is necessary to provide the visible light units 31 to help the user see the irradiation point of the laser beam, so as to prevent the user from mistaking the non-visible light.

Please also refer to FIG. 6 . From a cross-sectional view of this embodiment, it can be seen that the light-emitting circuit board 300 is close to the light-emitting surface 120 . Thereby, when the light-emitting surface 120 is close to the human body, the first sensor 41 and the second sensor 42 can easily sense that the human body is close to the light-emitting surface 120 to correspondingly generate the first trigger signal and the second sensor 42 . The second trigger signal.

In this embodiment, the thickness of a shell of the housing 100 disposed on the light-emitting surface 120 is less than 3 millimeters (mm). In this way, the light-emitting surface 120 is thin enough to facilitate the first sensor 41 and the second sensor 42 of the proximity sensing module 40 to sense the touch of the human body. The user's human body is a conductor, and the capacitive sensor senses the capacitive coupling caused by the user's skin to detect whether it is touched by the user. Specifically, because the light-emitting surface 120 is the dielectric material located between the human body and a sensing electrode of the capacitive sensor, a gap is formed between the human body, the light-emitting surface 120 and the sensing electrode. capacitance. Moreover, the electric field distribution of this capacitor will be changed by whether the human body touches the light-emitting surface 120. When a human body touches or approaches the light-emitting surface 120, the total charge on the sensing electrode will increase, and the electric field distribution between the light-emitting surface 120 and the sensing electrode will be changed. On the contrary, when the human body is away from the light-emitting surface 120, the capacitance is not formed between the air, the light-emitting surface 120 and the sensing electrode, and the total charge on the sensing electrode will be reduced. Therefore, the capacitance between the light-emitting surface 120 and the sensing electrode will be reduced. The electric field distribution is again changed. The first sensor 41 and the second sensor 42 of the proximity sensing module 40 sense whether the user's skin is touched through changes in the electric field. When the thickness of the light-emitting surface 120 is too thick, for example, greater than or equal to 3 mm, the distance between the conductors of the capacitor formed between the human body, the light-emitting surface 120 and the sensing electrode is too long, so resistance may occur. If it is too large, the electric field distribution between the light-emitting surface 120 and the sensing electrode changes too little during touch, and further causes a so-called poor sensing touch.

In this embodiment, each sensing electrode of the first sensor 41 and the second sensor 42 is a plane. The plane has an area of 9mm*12mm=108 square millimeters (mm ² ), and the thickness of the plane is only 0.1mm. The sensing electrode material of the capacitive sensor of the proximity sensing module 40 is copper foil.

Please refer to Figure 7, the present invention can be used with a fixing strap 400. The fixing strap 400 includes a fixing base 410 , and the fixing base 410 can fix the housing 100 so that the housing 100 is combined with the fixing strap 400 .

Please refer to FIG. 8 . In another embodiment, the fixing belt 400 includes two fixing seats 410 for fixing two wearable laser light therapy devices with safety protection functions of the present invention. Each fixing base 410 can fix multiple housings 100 . The fixing strap 400 strengthens the fixing form between the two fixing seats 410 .

Please refer to FIG. 9 . When the user uses the fixing strap 400 to fix the shell 100 to a part of the human body, for example, when fixing it to a painful knee 500 of the user, the fixing strap 400 will be fixed. The activation switch 20 on the housing 100 faces away from the user, and the fixing strap 400 fixes the light outlet 121 and the proximity sensing module 40 to face and fit the knee 500 . Two fixing seats 410 will be distributed on both sides of the knee 500 to fix the shell 100 respectively, so that the light outlet 121 of each shell 100 is aligned with the acupuncture points of the knee 500 to facilitate phototherapy. After the first sensor 41 and the second sensor 42 of each housing 100 touch the skin of the user's knee 500, the processing module 10 will determine that the proximity sensing module 40 generates the signal. A signal is triggered to cause the light-emitting module 30 to generate the phototherapy beam to soothe the user's knee 500 .

The present invention does not limit the user to only fixing the fixing belt 400 on the knee 500 . The user using the present invention can also fix the fixing belt 400 on any body part such as the neck, shoulder, elbow, wrist, waist or ankle of the human body to perform phototherapy massage and body soothing, and use a kind of photobiomodulation Photobiomodulation therapy uses the light therapy beam to stimulate muscles or joint tissues to repair and relieve pain.

The phototherapy beam generated by the present invention is a low-energy beam, but the light intensity of the phototherapy beam is still beyond the range that human eyes can adapt to. Therefore, the gist of the present invention is to use the proximity sensing module 40 as a safety mechanism. When the proximity sensing module 40 of the present invention senses that the human body is approaching the light emitting surface 120 and generates the trigger signal, the light outlet 121 will be close to the human body, such as the user's knee 500, so that the light emitting module The phototherapy beam generated by group 30 has no concern of directly hitting the user's eyes. That is to say, the processing module 10 confirms that the light-emitting module 30 is close to the knee 500 through the proximity sensing module 40 before generating the phototherapy beam through the light-emitting module 30 . Thereby, the present invention can significantly reduce the risk of the phototherapy beam directly hitting the user's eyes.
