Embodiments of the present invention provide a light therapy device that is suitable for any light therapy apparatus with high average power density, including but not limited to treating alzheimer's disease, depression, and the like, and also not limited to irradiation parameters such as wavelength, pulse frequency, and the like of near-infrared light.

As shown in fig. 1 to 3, the light treatment device includes a head cap, a cold air supply mechanism 2, and a hot air pumping mechanism 3. The headgear includes housing assembly 1, and housing assembly 1 includes that shell 11, transparent inner shell 12 and interval cover body 13, be formed with the cavity between shell 11 and the inner shell 12, interval cover body 13 is used for with the cavity is separated into as outer first cavity 14 and as the second cavity 15 of inlayer, be equipped with a plurality of lamp plates 4 that are used for launching near infrared light in the first cavity 14, seted up on the inner shell 12 with a plurality of air vents 16 of second cavity 15 intercommunication. The cold air supply mechanism 2 is communicated with the second chamber 15 and is used for supplying cold air into the second chamber 15 so that the cold air is blown to the scalp of the patient through the second chamber 15 and the vent hole 16. Hot gas pump drainage mechanism 3 with first cavity 14 intercommunication for with the heat that lamp plate 4 produced forms hot gas and takes out and discharge outside casing assembly 1.

Specifically, the outer shell 11 may be understood as a shell located at an outer layer away from the head when the headgear is worn, the inner shell 12 may be understood as a shell located at an inner layer close to the head when the headgear is worn, and the shapes of the outer shell 11 and the inner shell 12 may each be substantially hat-shaped. The spacer enclosure 13 is located between the outer shell 11 and the inner shell 12, and the shape of the spacer enclosure 13 may correspond to the shape of the outer shell 11 and the inner shell 12, e.g., the shape of the spacer enclosure 13 is also hat-shaped.

Specifically, shell 11 and the interval cover body 13 enclose and put and form above-mentioned first cavity 14, and inner shell 12 and interval cover body 13 enclose and put and form above-mentioned second cavity 15, set up lamp plate 4 in first cavity 14, can make lamp plate 4 keep away from the head to a certain extent to reduce the influence of the produced heat of lamp plate 4 work to the head temperature and guarantee certain security. In order to ensure that the near infrared light emitted by the lamp panel 4 can directly irradiate the scalp, the inner shell 12 and the spacer cover 13 are made of transparent materials, so as to reduce the loss of the near infrared light and guide the near infrared light to the scalp as much as possible.

In some alternative embodiments, the ventilation hole 16 formed on the inner casing 12 can be used for blowing the cold air in the second chamber 15 to the scalp, and can also be used for transmitting light, i.e. the light emitted by the lamp panel 4 is emitted to the scalp through the ventilation hole 16. In addition, the size of the ventilation hole 16 can be determined according to the air volume and the air speed blown to the scalp, so that the comfort level of the cold air discharged from the ventilation hole 16 blown to the scalp can be increased through the proper size of the ventilation hole 16, the feeling of a patient can be improved, and especially for a part of patients with poor tolerance, the part of patients can better receive light treatment.

In some alternative embodiments, as shown in fig. 4, after the patient wears the above-mentioned light treatment device, a space is formed between the inner shell 12 of the headgear and the scalp of the patient, that is, the head of the patient is not tightly attached to the inner surface of the inner shell 12, and the cool air discharged from the vent hole 16 enters the space to provide a more comfortable light treatment environment for the patient, so as to avoid the vent hole 16 being blocked by the head of the patient, which results in the cool air not being discharged effectively. In particular, the above-described housing assembly 1 has a fixed structure and dimensions, which accommodate the head of the patient in a loose manner. Specifically, certain allowance is reserved for the structure of the housing assembly 1, so that when the patient rotates within a preset angle range or moves up and down within a preset distance range, the housing assembly 1 can still cover the target brain area, and the lamp panel 4 can be used for irradiating each target brain area if needed. Further, the loose and open design of the housing assembly 1 can be adopted with a fixed and unchangeable structure and size for patients with individual differences in head shape and size to some extent, without having to customize the housing assembly 1 to be strictly adapted to the head shape and size of the patient for the individual patient, so that the housing assembly 1 can be manufactured in a standardized manner, the manufacturing cost is lower, the patient-adapted population of the head cap is wider, and the facility purchase and maintenance cost of the phototherapeutic device using medical places such as hospitals and communities is reduced. In particular, by fixed configuration and dimensions, it is meant that the housing assembly 1 may be provided without moving components, or even be moulded in one piece, thereby increasing the service life of the housing assembly 1 and simplifying the structure of the housing assembly 1.

In some alternative embodiments, the cool air supply mechanism 2 may be connected to a machine capable of producing cool air, such as a refrigerator, which transmits cool air into the cool air supply mechanism 2 after producing cool air, and then transmits the cool air into the second chamber 15 through the cool air supply mechanism 2, and then discharges the cool air to the scalp through the vent 16 communicated with the second chamber 15, so as to achieve the effect of cooling the scalp, and improve the comfort of the patient wearing the head cap for performing phototherapy, so that the temperature near the scalp of the patient can be between 18 degrees and 43 degrees. Preferably, the temperature near the patient's scalp is no higher than 40 degrees, and since this temperature is close to body temperature, patients feel comfortable even when sensitive and tolerant to temperature and do not suffer thermal damage, so that they can continue to receive treatment. By such a cold air supply means 2 in combination with the loosely designed housing assembly 1 as described above, the patient is more likely to receive continuous light irradiation treatment, and a single irradiation can last longer (for example, 20 minutes or even 30 minutes, and the heat generation near the scalp is higher as the time is longer), thereby further improving the treatment effect.

In some alternative embodiments, as shown in fig. 1 and 2, the cool air supply means 2 may be connected to the top of the housing assembly 1, and of course, the cool air supply means 2 may also be connected to the side of the housing assembly 1, such as near the back of the brain, which is not limited in this application.

In some alternative embodiments, the hot air pumping mechanism 3 may be connected to a machine capable of pumping air, such as a suction fan, which sucks out the hot air in the first chamber 14 through the hot air pumping mechanism 3, of course, in order to ensure that the air pressure in the first chamber 14 is stable, the first chamber 14 may be communicated with the outside, so as to allow the outside air to enter the first chamber 14 in time when the air is pumped out, thereby maintaining the air pressure in the first chamber 14 at the atmospheric pressure.

So, can avoid the steam in the first cavity 14 to stretch to the second cavity 15 in, lead to more heats to scatter to patient's head, cause the discomfort, also can avoid being used for entering into first cavity 14 for the cold wind of patient's head cooling, the influence is to the cooling effect of patient's head.

In particular, the lower end of the aforementioned spacer enclosure 13 may be sealingly connected to the outer shell 11 and/or the inner shell 12, so that the first chamber 14 and the second chamber 15 on opposite sides of the spacer enclosure 13 can be separated.

In particular, the spacer housing 13 may be made of a material with poor thermal conductivity to prevent heat in the first chamber 14 from being conducted more to the spacer housing 13, resulting in a consequent increase in the temperature of the second chamber 15.

In some embodiments, as shown in fig. 1 and 3, an air inlet 17 for introducing cold air from the cold air supply mechanism 2 is opened at the top of the partition enclosure 13, and an air guide surface corresponding to the air inlet 17 is formed on the outer top surface of the inner casing 12, so that the cold air entering through the air inlet 17 is guided to the periphery, so as to dissipate heat of the whole head. In some embodiments, the air guide surface may be configured as any structure capable of making the cold air disperse to the periphery, such as a concave shape, an arched shape, and the like.

In some embodiments, as shown in fig. 1 and 3, at least a central portion of the top of the inner shell 12 is formed with a flat surface.

In some alternative embodiments, the plane of the top of the inner casing 12 is disposed above and below the air inlet 17, so that the cold air entering from the air inlet 17 can directly flow to the plane.

In some embodiments, as shown in fig. 1 and 5, a spiral air guiding structure 5 is disposed at the air inlet 17 for guiding the flow direction of the supplied cold air, so that the cold air can be blown around, and the uniform cooling effect is further improved.

In some alternative embodiments, the spiral wind guiding structure 5 is detachably mounted at the air inlet 17. Specifically, the spiral wind guiding structure 5 may include a substrate and a spiral wind guiding blade disposed on the substrate, the substrate may be connected to the air inlet 17, and a through groove is disposed at a position of the substrate corresponding to the spiral wind guiding blade, so that the cool air is blown to the spiral wind guiding blade from the through groove and is exhausted into the second chamber 15 after being spirally wind-guided by the spiral wind guiding blade.

So, can play the effect of sheltering from to first cavity 14 and suction opening 18, avoid the foreign matter to fall by suction opening 18 in to first cavity 14, can also avoid operating personnel maloperation to stretch into first cavity 14 by suction opening 18 in, can improve equipment's security.

In some alternative embodiments, the stop structure 6 may have a cylindrical body, the stop plate 61 is configured as the bottom of the cylindrical body, each pumping hole 62 is located at the wall of the cylindrical body, and the gas in the first chamber 14 is pumped out through the pumping hole 62 at the wall.

In some alternative embodiments, the two opposite sides of the stop structure 6 may extend to form a connecting portion through which the stop structure 6 is installed at the suction opening 18.

In some alternative embodiments, the air suction opening 18 is disposed at the top of the housing 11, and the air suction opening 18 can be disposed close to the air inlet 17, so that the structural design of the headgear is more compact and the layout is more reasonable.

In some embodiments, as shown in fig. 6, a plurality of the pumping holes 62 are annularly arranged around the stop plate 61, so that the gas in the first chamber 14 can be uniformly pumped into the hot gas pumping mechanism 3 through the annularly arranged pumping holes 62.

Specifically, the suction holes 62 may be uniformly arranged around the stopper plate 61.

In some embodiments, as shown in fig. 1 and fig. 3, the lamp panels 4 are arranged in an array, the array of the lamp panels 4 is disposed outside the partition cover 13, and the plurality of air holes 16 are formed in groups, so that each group of air holes 16 corresponds to each lamp panel 4.

In some optional embodiments, the array of the lamp panels 4 may be set according to a treatment scheme, for example, when the light treatment device is used for treating depression, the treatment may be performed on the forehead and the left and right temporal lobes of the brain of a human, and therefore, the lamp panels 4 may be set in the first chamber corresponding to the forehead and the left and right temporal lobes of the head to perform light treatment on the forehead and the left and right temporal lobes of the patient; for example, when the above-described light therapy device is used for treating alzheimer's disease, the whole brain of a human can be treated, and therefore, the lamp panel 4 can be additionally provided at a position corresponding to the whole brain in the first chamber to perform light therapy on the whole brain of the patient. In this way, the array of the lamp panel 4 may be adaptively selected based on different diseases to be treated in a targeted manner.

Further, after the array mode of lamp plate 4 is confirmed, the arrangement mode of each group of vent holes 16 can be confirmed according to the array mode of lamp plate 4, namely the air-out position of the cold air is adjusted, so that the cold air volume and the air speed discharged by vent holes 16 can be more suitable for patients.

Specifically, in addition to the ventilation holes 16 staggered with the light-emitting body 41, the other group of ventilation holes 16 can be arranged corresponding to the light-emitting body 41, so that the near infrared light emitted by the light-emitting body 41 can directly irradiate the scalp, and a better light treatment effect is achieved.

Specifically, the lamp panel 4 may include a circuit board and a plurality of light emitters 41 disposed on the circuit board, and the light emitters 41 may be configured as near-infrared light emitting diodes.

In some embodiments, the number of the ventilation holes 16 in each group is greater than the number of the light emitters 41 on the lamp panel 4 corresponding to the ventilation holes. Therefore, the uniform cold air discharge effect can be improved by increasing the number of the vent holes 16, and a better scalp cooling effect is achieved.

For example, the number of the vent holes 16 included in one set of vent holes 16 may be 11 to 15, and the number of the light emitters 41 on one lamp panel 4 corresponding to the vent holes may be 8 to 10.

In some embodiments, the areas of the inner shell 12 for opening the sets of ventilation holes 16 include a first area and a second area, the first area covers the corresponding lamp panels 4, and the second area surrounds the first area to increase the cold air blowing area of the ventilation holes 16, so as to improve the comfort of the scalp during phototherapy.

In some embodiments, the aperture of the lower set of vent holes is larger than the aperture of the upper set of vent holes. The lower set of vents can be understood to be vents away from the corresponding overhead region of the inner shell, and the upper set of vents can be understood to be vents near the corresponding overhead region of the inner shell. So, can make cold wind more evenly discharge through the air vent, promote the cooling effect, avoid cold wind from the more of top diffusion, influence the cooling effect of other positions.

In some embodiments, as shown in fig. 1 and 3, each set of vents 16 radiate from the center to the periphery. Thus, the cold air can flow to the scalp in a scattered manner, and the heat of the scalp can be uniformly dissipated.

In some embodiments, as shown in fig. 1 and 7, a heat dissipation fin 42 is disposed on the second panel surface of the lamp panel 4, and the heat dissipation fin 42 extends in a direction away from the spacer housing 13.
