Description

Technical Field

[0002] Intense pulsed light, or pulsed intense light, is a wide-spectrum light formed by focusing and filtering a very high-intensity light source. Therefore, it can cover a variety of target color bases, such as melanin, oxygenated hemoglobin, water, etc., and has a wide range of clinical uses.

[0003] The therapeutic effect of an IPL device is generally significantly affected by two key parameters: output energy and repetition frequency.

Although the output energy is increased, the repetition frequency does not change, resulting in the IPL device still not achieving the best therapeutic effect. Therefore, we propose an IPL device to solve the above problems. Utility Model Content

[0032] The present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the relevant invention, rather than to limit the invention. It is also necessary to explain that, for ease of description, only the parts related to the invention are shown in the accompanying drawings.

[0033] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0034] In order to make the description of the following embodiments clear and concise, a brief introduction to the related technology is first given:

[0035] The basic working principle of the intense pulsed light therapy machine is to use a trigger to apply high voltage to xenon gas, triggering the ionization of xenon gas. After a relatively long period of charging through the energy storage capacitor, it discharges in a very short time, causing avalanche ionization of xenon gas in the lamp tube. The xenon gas converts and releases the charged energy in the form of high-intensity light radiation. This discharge process is a light pulse. The therapeutic effect of the intense pulsed light therapy machine is significantly affected by two key parameters: output energy and repetition frequency. Among them, the output energy determines the depth of its penetration into the skin and the intensity of the thermal effect generated. The repetition frequency refers to the number of times the pulsed light is emitted per second, and the repetition frequency determines the size of the light energy impact given per unit time.

[0036] In order to make the intense pulsed light therapy device provided in the embodiment of the present application clearer and easier to understand, the device is described below in conjunction with the accompanying drawings. Figure 1 As shown in the figure, this figure is a schematic diagram of the structure of an intense pulsed light therapy device provided in an embodiment of the present application, and the device includes:

[0037] The shell 1 is hollow inside to form an installation chamber; the shell 1 is also provided with a first opening, which is connected to the installation chamber. Figure 2 A in the middle represents the first opening, which serves as the light outlet of the device.

[0038] Two groups of light generating components are arranged in the installation chamber; the light generating components include: a xenon lamp light source 2 and a driving power supply 3 electrically connected to the xenon lamp light source 2; the xenon lamp light sources 2 of the two groups of light generating components are arranged in parallel; a focusing member 4 is also provided on the side of the two xenon lamp light sources 2 away from the first opening, which is used to reflect the light emitted by the xenon lamp light source 2 to the first opening position.

[0039] It should be noted that the straight-line distances from the central axes of the two xenon lamp light sources 2 to the first opening are equal to ensure that the light emitted by the two xenon lamp light sources 2 reaches the first opening in the same manner. When the two xenon lamp light sources 2 are turned on at the same time, more uniform light energy can be formed. Here, the two xenon lamp light sources 2 are, for example, xenon lamps of the same model, and the extension direction of the axial axes of the two xenon lamps is perpendicular to the axis of the first opening. When using this device, as much light as possible from the xenon lamp can be vertically irradiated on the target treatment area, so that the output can be more uniform. Compared with the traditional arrangement of xenon lamps, this application can reduce the problem of mutual occlusion of the light path between xenon lamps. In addition, the specific specifications of the two sets of light generating components and the focusing element 4 can be set according to actual needs to avoid the problem that a certain working mode cannot be achieved.

[0040] In addition, the spacing between the two xenon lamp light sources 2 can be set according to actual needs; for example, from the perspective of space limitations, heat dissipation management and light energy, paying attention to the mutual constraints of minimum installation size and maximum handheld size, temperature field, luminous flux, illumination uniformity, and spot shape, the spacing between the two xenon lamp light sources 2 can be determined by iterative simulation design to meet assembly conditions and avoid heat accumulation and heat island effect while obtaining relatively high-quality and uniform light energy.

[0041] The driving power source 3 controls the corresponding xenon lamp light source 2 separately, so that the two xenon lamp light sources 2 can emit light separately, emit light simultaneously or emit light alternately, so that the whole device has more working modes and is more widely and flexibly applied. Here, the driving power source 3 is, for example, a battery.

[0042] The focusing element 4 is used to reflect the light emitted by the two xenon lamp light sources 2 to the first opening position, and the type of the focusing element 4 is, for example, an elliptical concave mirror, and the major axis of the cross section of the elliptical concave mirror is perpendicular to the central axis of the xenon lamp light source 2. This arrangement allows the light emitted by the two xenon lamp light sources 2 to be reflected by the focusing element 4 to the maximum extent, thereby obtaining a larger and uniform light spot area.

[0043] In addition, a filter 12 is provided at the first opening to filter out stray light; the filter 12 is used to filter out the undesired spectrum, and the type of the filter 12 can be selected according to actual needs. In addition, since the filter 12 may be replaced, an elastic card slot can be designed at the first opening to accommodate and fix the filter 12, making it easier to replace. Here, a coating method can also be used to filter out stray light.

[0044] The control unit is respectively connected to the two driving power supplies 3 for communication, and the control unit is used to control the working states of the two groups of light generating components.

[0045] The type of the control unit is, for example, a PLC processing chip, and its model is, for example, Siemens S7-400. Figure 4 As shown, the control unit can independently control the start and stop of the two driving power supplies 3, and then control the brightness of the two xenon lamp light sources 2, thereby forming a variety of working modes, so that the device can provide different combinations of output energy and repetition frequency to meet different usage requirements.

[0046] Specifically, when the two groups of light generating components work at the same time, the total output energy can be increased, which can improve the treatment speed to a certain extent; when the two groups of light generating components work separately, one xenon lamp light source 2 works normally and the other xenon lamp light source 2 can rest, or, when one of the xenon lamp light sources 2 fails, the other xenon lamp light source 2 can still work normally, ensuring the continuous availability and reliability of the device; when the two groups of light generating components work alternately, the repetition frequency is increased while maintaining the overall output energy level.

[0047] For example, when low energy output is required, the control unit can control one of the xenon lamp light sources 2 to be in a lit state, and can also allow the two xenon lamp light sources 2 to be periodically alternately lit so that the unlit xenon lamp light source 2 has a sufficient intermittent period to extend the service life of the entire device.

[0048] Compared with the traditional intense pulse therapy machine, the present application improves the output energy of the device by designing two xenon lamp light sources 2 arranged in parallel in the shell 1, and the two xenon lamp light sources 2 belong to two independent light generating components. The control unit is used to separately control the working status of the two groups of light generating components, so that the device has a variety of different working modes. For example, the two groups of light generating components work simultaneously, separately or alternately, etc., which can meet more different usage requirements, and can also improve the repetition frequency to a certain extent, ensuring the continuity and reliability of treatment.

[0049] Furthermore, the device further comprises: two groups of cooling components, the cooling components are arranged on the inner wall of the installation chamber, and the two groups of cooling components and the two xenon lamp light sources 2 are arranged in a one-to-one correspondence;

[0050] The cooling assembly comprises a circulating cooling member, which is arranged on a side of the xenon lamp light source 2 away from the first opening, and the circulating cooling member is connected to the corresponding xenon lamp light source 2 .

[0051] The cooling components have their own cooling water circulation systems. The two cooling components cool the corresponding xenon light sources 2 separately, which can ensure that each xenon light source 2 is fully and accurately cooled, and prevent the xenon light source 2 from overheating and affecting its working performance. The circulating cooling component can be a plate structure with good energy conduction. Here, the cooling component is a conventional cooling structure well known to those skilled in the art, and its specific structure is not the focus of the design of this application. For example, Figure 3The B in the figure indicates a circulating cooling unit.

[0052] Furthermore, the device further comprises: an adjusting structure, which is arranged between the inner wall of the installation chamber and the two groups of cooling components, and is used to adjust the positions of the two xenon lamp light sources 2 relative to the first opening.

[0053] It should be noted that when the two light generating components work separately, in order to ensure uniform output of light energy, the present application also designs an adjustment structure, which is used to adjust the xenon lamp light source 2 in the lit state to the center position of the first opening. Figure 5 As shown, the focusing member 4 leaves enough moving space for the two groups of light generating components to avoid interference between the two groups of light generating components and the focusing member 4 when the adjustment structure is activated.

[0054] Specifically, Figure 3 As shown, the regulatory structure includes:

[0055] A base 5 is arranged on the inner wall of the installation chamber; the base 5 is provided with a driving motor 6; the driving motor 6 is connected to one end of the cooling assembly through a transmission assembly;

[0056] A first bearing 7, the inner ring of the first bearing 7 is connected to the inner wall of the mounting chamber; the outer ring of the first bearing 7 is provided with a supporting turntable 8, and the supporting turntable 8 is connected to the other end of the cooling assembly;

[0057] The drive motor 6 is communicatively connected to the control unit, and the control unit is used to control the start and stop of the drive motor 6 .

[0058] The transmission components include:

[0059] A first bevel gear 9, which is arranged at a driving end of the driving motor 6;

[0060] The second bearing 10, the inner ring of the second bearing 10 is connected to the inner wall of the mounting chamber, and it is arranged corresponding to the first bearing 7; the outer ring of the second bearing 10 is provided with a second bevel gear 11, the second bevel gear 11 is connected to the cooling assembly through a connecting shaft, and the first bevel gear 9 and the second bevel gear 11 are meshed.

[0061] The control unit starts the drive motor 6, and the drive end of the drive motor 6 drives the first bevel gear 9 and the second bevel gear 11 to rotate, thereby driving the cooling component and the light generating component to rotate, so that the corresponding xenon lamp light source 2 rotates to the center position corresponding to the first opening, thereby achieving the purpose of outputting uniform light energy.

[0062] The above description is only a preferred embodiment of the present application and an explanation of the technical principles used. Those skilled in the art should understand that the scope of the invention involved in the present application is not limited to the technical solution formed by a specific combination of the above technical features, but should also cover other technical solutions formed by any combination of the above technical features or their equivalent features without departing from the inventive concept. For example, the above features are replaced with (but not limited to) technical features with similar functions disclosed in the present application.
