Description

Technical Field

[0001] The present application relates to the technical field of medical devices, and in particular to a blue light therapy device. Background Art

[0002] Neonatal jaundice is the most common neonatal disease caused by abnormal serum bilirubin metabolism, which accumulates in the skin, mucous membranes, sclera, and certain body fluids, resulting in a yellowing of the newborn's skin. Neonatal jaundice can be divided into physiological jaundice and pathological jaundice. In physiological jaundice, serum bilirubin levels generally rise gradually within the first week of birth and then slowly subside. In pathological jaundice, serum bilirubin levels are abnormally elevated. If left untreated, it can harm the nervous system and, in severe cases, even lead to death.

[0003] The most common treatment for pathological jaundice is blue light therapy. Specifically, the baby's eyes and genitals are shielded, and blue light is applied to other exposed areas of the skin for a long time. This converts free bilirubin compounds in the subcutaneous tissue from being fat-soluble to water-soluble, allowing them to be excreted through body fluids.

[0004] In related technologies, current blue light therapy devices generally have low power, emit low intensity blue light, and very little blue light reaches the baby's subcutaneous tissue. The efficiency of decomposing bilirubin is low, and long-term irradiation is required to eliminate jaundice. The treatment effect on neonatal jaundice is not ideal. Utility Model Content

[0032] As described in the background art, if the pathological jaundice of newborns caused by abnormally elevated serum bilirubin is not treated in time, it will harm the nervous system and even lead to death in severe cases. Among them, the most common treatment method is blue light irradiation therapy. Specifically, the eyes and reproductive parts of the baby are blocked, and a blue light lamp is used to irradiate the skin of other exposed parts for a long time, so that the free bilirubin compounds in the subcutaneous tissue are changed from fat-soluble to water-soluble, and then excreted from the body through body fluids. In the related art, the power of blue light therapy devices is generally low, the intensity of the blue light emitted is small, and the blue light reaching the baby's subcutaneous tissue is very small. The decomposition efficiency of bilirubin is low, and long-term irradiation is required to make the jaundice subside. The treatment effect for neonatal jaundice is not ideal.

[0033] Based on this, the present application provides a method of using an LED light source to emit short, high-intensity blue light at intervals to irradiate the baby's skin, so that more blue light components reach the subcutaneous tissue, accelerate the decomposition efficiency of bilirubin, and thus shorten the duration of jaundice treatment, avoiding the safety hazards caused by long-term blue light exposure to the baby.

[0034] In an exemplary embodiment, referring to Figure 1 , provides a blue light therapy device, including: an MCU module 100 that outputs a trigger voltage; an LED driver module 200 that generates a driving current according to the received trigger voltage; an LED light source 300 that is in a flash mode or a normal mode according to the driving current, wherein the LED light source 300 in the flash mode is used to emit short-term high-intensity blue light at intervals.

[0035] Specifically, the blue light therapy device proposed in this application can control the magnitude of the driving current generated by the LED driver module 200 by the magnitude of the trigger voltage of the MCU module 100, thereby enabling the LED light source 300 to have different operating modes, aiming to achieve efficient jaundice treatment on a safe basis. For example, when the driving current generated is a periodic pulse current, the LED light source 300 can operate in a flash mode, emitting short, high-intensity blue light at intervals; when the driving current generated is a constant current value, the LED light source 300 can operate in a normal mode, emitting stable blue light for a long time.

[0036] It is understood that in strobe mode, the driving current received by the LED light source 300 is a high current with a high amplitude, which makes the blue light emitted by the LED light source 300 have a higher illumination intensity, which can ensure that more blue light components reach the subcutaneous tissue of the treated infant, and more blue light is absorbed by bilirubin, resulting in a better treatment effect. However, due to the increase in ambient temperature that high-intensity blue light inevitably brings, in order to avoid sunburn of the treated infant, the driving current received by the LED light source 300 in strobe mode is still periodic and of a short duration, causing the LED light source 300 to be in a flashing state. This method of emitting short, high-intensity blue light at intervals can reduce the continuous light exposure time of the infant while ensuring the treatment effect, thereby avoiding injury to the treated infant.

[0037] The MCU module 100 is responsible for overall control of the blue light therapy device. It receives an external startup command to initiate operation and outputs a trigger voltage to the LED driver module 200 via its output terminal. It is understood that the trigger voltage is an analog signal, which serves as the basis for the overall control of the MCU module 100 and controls the operating mode of the blue light therapy device.

[0038] For example, the MCU module 100 can be implemented using a microcontroller unit (MCU), or it can be replaced with other controllers or control chips that can achieve overall control according to the needs of technicians, as long as the control functions mentioned in this application can be achieved.

[0039] Furthermore, the LED driver module 200 may be composed of a current driver module, with its input end connected to the MCU module 100 and its output end connected to the LED light source 300. It is understood that the current driver module may be implemented by a driver chip or other driver circuits. The embodiments of this application do not limit the specific implementation structure, and those skilled in the art may select a structure based on actual needs, as long as it can achieve a constant current drive current output in the normal mode and a periodic pulse current drive current output in the strobe mode.

[0040] Furthermore, the LED light source 300 is comprised of blue LED lamp beads that can output blue light. In one exemplary embodiment, the LED lamp beads emit blue light with a wavelength of 400-500nm. It is understood that the blue light corresponding to this wavelength band is part of the visible light spectrum, belonging to the shorter wavelength, higher energy light in the electromagnetic spectrum. Specifically, embodiments of the present application may utilize LED lamp beads that emit blue light with a wavelength of 450nm. This wavelength of blue light has relatively high energy and is known as high-energy short-wave blue light, which is more effective in treating jaundice.

[0041] In an exemplary embodiment, the LED light source includes a plurality of LED modules, wherein the LED module is composed of a plurality of LED lamp groups connected in parallel, and the LED lamp group is composed of a plurality of LED lamp beads connected in series.

[0042] Specifically, the LED light source can be an array of LED lamp beads, each row or column of lamp beads is connected in series to form an LED lamp group, and then multiple rows or columns of LED lamp groups are connected in parallel to form an LED module, and finally all LED modules are combined into a whole LED light source.

[0043] Reference Figure 2 The LED light source 300 includes multiple LED modules 310. Each LED module 310 receives a drive current IC from the LED driver module 200 and operates in either strobe mode or normal mode depending on the drive current IC. Each LED module 310 is composed of multiple LED lamp groups 311 connected in parallel, each of which is composed of multiple LED lamp beads connected in series.

[0044] It can be understood that, in an exemplary embodiment, the blue light therapy device further includes a treatment box (not shown in the figure), and the LED light source is disposed in the treatment box.

[0045] Specifically, the treatment box is used to place the infant being treated, and then the LED light source inside the treatment box is used to provide irradiation therapy. By designing the material and shape of the treatment box, it can effectively concentrate the blue light emitted by the LED light source, achieving more efficient blue light therapy for the infant being treated.

[0046] Optionally, a heat dissipation device may be provided in the treatment box, and a heat dissipation through-hole may be provided on the heat dissipation device. The temperature in the treatment box may be lowered by the heat dissipation device and the heat dissipation through-hole to prevent the treated baby in the treatment box from feeling uncomfortable due to excessive temperature.

[0047] For example, the arrayed LED light source may be provided in the treatment box in the form of a rotatable probe, so that the irradiation area of ​​the LED light source on the treated baby can be adjusted more conveniently.

[0048] The above-mentioned blue light therapy device outputs a trigger voltage through the MCU module, and the LED driver module generates a driving current according to the received trigger voltage, and finally drives the LED light source in a flash mode or a normal mode according to the driving current. Among them, when the neonatal jaundice index is high, the LED light source in the flash mode can emit short periods of high-intensity blue light at intervals to illuminate the baby's skin. The blue light component reaching the subcutaneous tissue will increase, which will accelerate the decomposition efficiency of bilirubin, thereby shortening the duration of jaundice treatment and avoiding the safety hazards caused by long-term blue light exposure to the baby.

[0049] Optionally, the blue light therapy device provided in the present application may also include a jaundice numerical detection module, which can be used to determine the jaundice index of the treated infant, and then automatically select the target working mode based on the jaundice index of the treated infant.

[0050] For example, if the jaundice index of the treated infant is greater than a preset jaundice value, the target operating mode can be determined to be strobe mode. The MCU module can then output a trigger voltage corresponding to the strobe module, triggering the LED driver module to generate a periodic pulse drive current, causing the LED light source to operate in strobe mode and intermittently emit short bursts of high-intensity blue light to treat the treated infant. If the jaundice index of the treated infant does not reach the preset jaundice value, the target operating mode can be determined to be normal mode. The MCU module can then output a trigger voltage corresponding to the normal module, triggering the LED driver module to generate a constant-amplitude drive current, causing the LED light source to operate in normal mode and continuously emit stable blue light for a long period of time to treat the treated infant.

[0051] The jaundice value detection module can be located in the same location as the LED light source and used for contactless detection of the jaundice index of the treated infant. Specifically, the jaundice value detection module can include a jaundice detection light source and a photoelectric conversion circuit. The light emitted by the jaundice detection light source can be irradiated onto the skin of the treated infant through a focusing lens. The light waves are reflected by the skin, and the reflected light is then irradiated back to the jaundice value detection module through the focusing lens. The photoelectric conversion circuit then converts the optical signal into an electrical signal. The electrical signal is amplified and transmitted to the MCU module, which calculates the jaundice index.

[0052] Of course, the method of selecting the target working mode can also be based on the user's selection operation, and the user's manual method must take precedence over the automatic selection to ensure the safety of the treated baby.

[0053] Specifically, the user can set the desired working mode through the interactive module of the blue light therapy device, and then control the blue light therapy device to work according to the set working mode. For example, when the user sets the working mode to strobe mode through the interactive module, the MCU module outputs the trigger voltage corresponding to the strobe module, triggering the LED driver module to generate a driving current with periodic pulses, so that the LED light source works in strobe mode and emits short-term high-intensity blue light at intervals. When the user sets the working mode to normal mode through the interactive module, the MCU module outputs the trigger voltage corresponding to the normal module, triggering the LED driver module to generate a driving current with a constant amplitude, so that the LED light source works in normal mode and emits stable blue light for a long time.

[0054] Optionally, because blue light's high energy and penetrating power can be harmful to the human eye, particularly the retina, infants undergoing treatment must cover their eyes. After the MCU module starts running and determines the target operating mode, it can wait for a preset time before outputting the trigger voltage corresponding to the target operating mode, protecting users (for example, medical staff in hospital settings) from blue light damage.

[0055] In an exemplary embodiment, the number of LED driving modules matches the number of LED modules, and each LED module is driven to emit light by its corresponding connected LED driving module.

[0056] Specifically, the number of LED driver modules matches the number of LED modules. For example, the number of LED driver modules can be equal to the number of LED modules, with one LED driver module connected to one LED module to drive lighting. Alternatively, the number of LED modules can be a preset multiple of the number of LED driver modules, with one LED driver module connected to a preset number of LED modules to drive lighting. For example, if the number of LED modules is twice the number of LED driver modules, one LED driver module needs to be connected to two LED modules to drive lighting.

[0057] Reference Figure 3 In the embodiments of this application, the number of LED driver modules 200 is equal to the number of LED modules 310, and each LED driver module 200 is connected to a corresponding LED module 310 for driving light. Each LED driver module 200 outputs a driving current to its connected LED module 310 to drive the corresponding LED module 310 to emit light.

[0058] Exemplarily, based on the fact that each LED module is connected and driven by a different LED driver module, the light-emitting area of ​​the LED light source provided by the embodiment of the present application can be adjusted. It can be understood that, based on different needs, the MCU module can output trigger voltages of different amplitudes to control the light-emitting area of ​​the LED light source. For example, under the control of a trigger voltage of a first amplitude output by the MCU module, the LED modules in the first light-emitting area of ​​the LED light source can receive the driving current output by the LED driver module to which they are connected and emit light, while the LED modules in other areas are extinguished because the connected LED driver module has no driving current output. Under the control of a trigger voltage of a second amplitude output by the MCU module, the LED modules in the second light-emitting area of ​​the LED light source can receive the driving current output by the LED driver module to which they are connected and emit light, while the LED modules in other areas are extinguished because the connected LED driver module has no driving current output. Among them, the first light-emitting area and the second light-emitting area are different light-emitting areas on the LED light source.

[0059] In an exemplary embodiment, Figure 4 As shown, the blue light therapy device of the present application also includes a power module 400, which connects the MCU module 100, the LED driving module 200 and the LED light source 300.

[0060] The power module 400 can be connected to an external power supply to obtain AC power, and its internal rectifier unit converts the AC power into DC power. The DC power is then converted through a voltage conversion unit to power modules such as the MCU module 100, the LED driver module 200, and the LED light source 300. For example, to power the MCU module 100, the voltage conversion unit of the power module 400 needs to convert the DC power into a 3.3V supply voltage, which is then provided to the MCU module 100. Furthermore, the power module 400 may also include a constant current drive unit for providing the driving current for the LED light source 300 operating in normal mode.

[0061] Preferably, the power module 400 may further include a voltage stabilizing unit for stabilizing the voltage of the AC power obtained from the connected external power supply terminal, thereby achieving a stable power supply effect for other modules.

[0062] In an exemplary embodiment, referring to Figure 4 The blue light therapy device of the present application also includes a current detection module 500 , which connects the LED driving module 200 and the MCU module 100 .

[0063] Specifically, the input end of the current detection module 500 is connected to the output end of the LED driver module 200, and the output end of the current detection module 500 is connected to the input end of the MCU module 100. During the operation of the blue light therapy device, the current detection module 500 is used to detect the driving current output by the LED driver module 200 in real time, that is, the current flowing through the LED light source 300, and feed it back to the MCU module 100.

[0064] Furthermore, when the current detection module 500 feeds back to the MCU module 100 that the driving current exceeds the preset current limit, the MCU module 100 may determine that an overcurrent has occurred in the blue light therapy device and send a power-off signal to the power module 400, so that the power module 400 performs a power-off process based on the received signal. It is understood that the power-off process performed by the power module 400 may be to cut off the connection with the external power supply terminal or to simultaneously cut off the power supply path to each internal module.

[0065] In an exemplary embodiment, referring to Figure 4The blue light therapy device of the present application also includes a temperature sensor module 600, which is arranged on the light board where the LED light source 300 is located, and the temperature sensor module 600 is connected to the MCU module 100.

[0066] Specifically, the output end of the temperature sensor module 600 is connected to the input end of the MCU module 100. The temperature sensor module 600 is set on the light board where the LED light source 300 is located. During the operation of the blue light therapy device, the temperature sensor module 600 monitors the temperature value of the LED light source 300 in real time and feeds it back to the MCU module 100.

[0067] Furthermore, if the temperature value fed back to the MCU module 100 by the temperature sensor module 600 exceeds the first temperature limit, the MCU module 100 may determine that the temperature of the LED light source 300 is excessively high, potentially damaging the LED lamp beads, and will send a power-off signal to the power module 400, causing the power module 400 to shut down the power supply based on the received signal. It will be appreciated that real-time monitoring of the temperature of the LED light source 300 can prevent damage to the LED lamp beads caused by excessive temperature, thereby extending the life of the LED light source 300.

[0068] In addition, a temperature sensor module 600 may be provided within the treatment chamber to monitor the temperature of the treatment chamber in real time during operation of the blue light therapy device and to provide feedback to the MCU module 100. If the temperature within the treatment chamber exceeds a second temperature limit, the MCU module 100 may determine that the temperature within the treatment chamber is excessively high and may pose a risk to the treated infant. The MCU module 100 will then send a power-off signal to the power module 400, causing the power module 400 to shut down the device based on the received signal, thereby terminating the entire device.

[0069] In an exemplary embodiment, referring to Figure 4 The blue light therapy device of the present application also includes an interactive module 700, which is connected to the MCU module 100.

[0070] Specifically, the interactive module 700 can be used for information input, such as receiving a user's selection to determine the target operating mode of the LED light source 300. The interactive module 700 can also be used for information output. For example, if an overcurrent condition is detected in the blue light therapy device, the temperature of the LED light source 300 is too high, or the temperature inside the treatment chamber is too high, the interactive module 700 can output an alarm message to inform the user of the abnormality.

[0071] Exemplarily, when used for information input, the interactive module 700 can be a display screen with a touch screen function, or a button, trackball or touchpad set on a blue light therapy device, or an external keyboard, touchpad or mouse, etc.

[0072] In an exemplary embodiment, when used for information output, the interactive module 700 may include an indicator light and an alarm. In situations such as when the blue light therapy device is determined to have an overcurrent, when the temperature of the LED light source 300 is determined to be too high, or when the temperature inside the treatment chamber is determined to be too high, the indicator light may light up and the alarm may sound, outputting an alarm message.

[0073] It is understood that the warning light can output different prompt information in the above different alarm situations. For example, if the blue light therapy device is determined to have an overcurrent, the warning light can correspondingly light up red to provide a prompt. If the temperature of the LED light source 300 is determined to be too high, the warning light can correspondingly light up yellow to provide a prompt. If the temperature inside the treatment box is determined to be too high, the warning light can correspondingly light up red and flash to provide a prompt.

[0074] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0075] The above-described embodiments merely represent several implementation methods of the present application. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that a person skilled in the art could make various modifications and improvements without departing from the spirit of the present application, all of which fall within the scope of protection of the present application. Therefore, the scope of protection of the present patent application shall be determined by the appended claims.
