Description

[0001] The invention relates to light-protective devices used when working in an area of ​​highly fluctuating light intensity, for example, in hardware cosmetology, and can be used to protect the eyes of a doctor (observer) from being blinded by intense pulsed light or laser radiation.

[0002] Intensive Pulse Light (IPL) technology is one of the most popular procedures in medical cosmetology. This technology is most often used in photorejuvenation and photoepilation devices. It is also effective for correcting pigmented and minor vascular skin defects.

[0003] Background of the invention. The KN-SPECTRUM device for IPL therapy is known, manufactured by KN ТЕСН (Russia). [See KN TECH. KN SPEKTRUM Equipment / URL: https: / / kn-tech.ru / oborudovanie / kn_spectrum / ]. ​​The device is monoblock, equipped with a movable handle, inside which a powerful light source is installed, providing IPL exposure to the patient's skin. The device is controlled using a trigger button in the handle, by pressing which the observer initiates a flash of high-intensity light. High-intensity pulsed light (IPL) is a type of broadband incoherent light radiation with a wavelength of 420-1200 nm, which, without eye protection, can cause burns to the human eye (see User Manual, p. 3).

[0004] When performing IPL therapy, the cosmetologist (observer) protects his or her vision from bright pulsed light using individual protective glasses with dark lenses with a degree of darkening from different manufacturers from 4 DIN to 13 DIN.

[0005] The effectiveness of eye protection using protective glasses with dark lenses is limited by a technical contradiction:

[0006] • The glasses should be as transparent as possible so that the doctor (observer) can see the surface of the patient’s skin being treated and, at the same time,

[0007] • Glasses must be as opaque as possible to protect the observer's vision from being blinded by high-intensity pulsed light or laser radiation.

[0008] As a result: increasing the darkening of the protective lenses of the glasses reduces the glare, but reduces the observer's visibility of the patient's skin surface, and decreasing the darkening of the protective lenses improves the visibility of the patient's skin, but causes temporary blindness of the observer.

[0009] A known prior art is a "welder's protective shield / mask / helmet," which protects the welder's eyes and face from arc radiation and metal spatter. It features a viewing hole with a glass (light filter) inserted into it, blocking infrared and ultraviolet rays and reducing the brightness of the arc's light beams [V.G. Gevorkyan, "Fundamentals of Welding," Moscow: Vysshaya Shkola, 1985, p. 37, Fig. 37]. During welding, the welder periodically lifts the mask to monitor the quality of the weld. The distracting manipulation of raising and lowering the protective mask creates inconvenience for the welder and, thus, negatively impacts the quality of the weld.

[0010] The "Electrochromic Device and Electrochromic Combination" is known from the existing state of the art, protected by patent RU2127442, IPC G02F 1 / 15 G02F 1 / 155 G02F 1 / 01. According to the technical solution embodied in this invention, the light transmittance of the protective glass (chromogenic device) depends on the electrical action of applied electrical pulses on the electrochromic glass.

[0011] The closest technical solution to the claimed invention is the "Protective device for an electric welder", patent RU 2036627 IPC A61F 9 / 06 (2006.01), comprising a housing with a headband (protective mask), in which a viewing window is fixed, containing an electrochromic glass as a light filter and a trigger element that includes a source of control voltage pulses. Electrochromic glass (glass with changing properties) [Smart glass - Wikipedia, URL: https: / / ru.wikipedia.org / wiki / Умное_стекло] is made of an optically opaque material in the absence of electrical voltage. It is connected to a source of control voltage pulses. The role of the trigger element of the device is played by a photodetector. The light from the igniting electric arc in the photodetector generates an electromotive force, which, through electrical communication lines, activates an electrochromic light filter, the reduction in transparency of which protects the observer's visual organ from blinding.[Application: 93019515 / 14, 1993.04.15. Application filing date: 1993.04.15. Published: 1995.06.09. Authors: Vladimir Fedorovich Romanovsky, Alexander Nikolaevich Kovalenko. Patent holders: Vladimir Fedorovich Romanovsky, Alexander Nikolaevich Kovalenko].

[0012] The range and smoothness of darkening adjustment of well-known welding masks is usually 5-9DIN / 9-13DIN. For welding work, the maximum switching time permitted by the EN379 standard when switching a light filter with an initial darkening of 4DIN to 13DIN is 4 milliseconds, and when switching from 4DIN to 9DIN, it is 200 milliseconds [How to choose the right chameleon welding mask? / ESVA.RU, URL: https: / / esva.ru / articles / sovety-pokupatelyam / kak-vybrat-svarochnuyu-masku-khameleon-pravilno.html].

[0013] The technical result of the prototype invention is achieved by initiating the darkening process of the electrochromic glass, which protects the observer's vision, by the light of an igniting electric arc. Since the electric arc does not ignite instantly, but gradually, the triggering mechanism (photodetector) via the control unit manages to transform the electrochromic glass (light filter) into an opaque state, thereby protecting the observer's vision from dazzle.

[0014] The disadvantage of the known device is the insufficient protection of the observer's visual organ from blinding by intense pulsed light due to the low response speed of the circuit: photodetector - electrochromic light filter, as well as due to the inertia of this system.

[0015] If during welding work, from the moment of the electric arc occurrence until the darkening of the light filter, electrochromic filters are triggered after 200 milliseconds, then with IPL exposure, the pulse duration is 2.2-8.0 milliseconds, and the pulse delay time is 15-50 milliseconds, which is clearly insufficient [IPL therapy: IPL technology and procedures. Table 3 and 4 / URL: https: / / www.premium-a.ru / articles-main / retrospektivnoe-issledovanie-klinicheskoj-effektivnosti-istochnikov-intensivnogo-impulsnogo-sveta-ipl / ]. In other words, when treating a patient's skin with IPL, where the light flash lasts 2.2-8.0 milliseconds, using a protective device with a 200-millisecond response time is pointless, as it won't have time to block or even significantly reduce the bright light. This will result in damage to the observer's vision.

[0016] The purpose of the invention is to increase the reliability of protection of the observer's visual organ from blinding by high-intensity pulsed light without impairing the observer's view of the skin surface.

[0017] Inventive concept. The technical result of the claimed invention is achieved by the observer initiating the darkening process of the electrochromic glass using a button on the handpiece, after which the high-intensity light flash of the IPL device is triggered.

[0018] The essence of the claimed invention.

[0019] The stated goal is achieved due to the fact that the trigger element of the device is located in the handle of the IPL device, with the possibility of subsequent switching on of the IPL device, and the control unit of the electrochromic glass is located in the protective mask of the observer and these two elements are connected by a wireless (for example, Bluetooth) communication line.

[0020] The technical solution of the claimed invention is shown in Fig. 1.

[0021] The trigger element of the device has a rod (1), on which a button (2) is located. The rod (1) has a stop (3), fixed relative to the rod, which, when moving, presses on the upper edge of the compression spring (6). The lower end of this spring (6) rests on a movable stop (5) that slides along the rod. When the button (2) is pressed, the stop (5), under the pressure of the spring (6), slides along the rod (1) and presses the contact (7), closing the electrical circuit (A-A). The activation of the trigger (closing the electrical circuit (A-A) activates the wireless transmitter (9), which is also installed in the IPL device handle. The transmitter (9) operates with the contact (7) closed for the entire time the trigger button (2) is pressed and held and the rod (1) moves downwards. With further downward movement, the rod (1) with its stop (4) presses on the contact (8), closing the electrical circuit (B-B) for turning on the high-intensity light source (14).When the observer releases button (2), rod (1) moves upward, first opening contact (8) and then contact (7). The movement of rod (1) ensures the transition of the compressed spring (6) to its initial state.

[0022] In essence, the trigger element in the handle is a push-button two-position switch with the ability to sequentially close the A-A power supply circuit of the wireless [for example, Bluetooth] transmitter (9) located inside the handle and, after an adjustable period of time, subsequently close the B-B electrical circuit of the IPL device control (14).

[0023] The protective mask of the device is equipped with a wireless [e.g. Bluetooth] receiver (11) that receives a signal (10) from the transmitter (9) in the handle, which in turn changes the transparency of the electrochromic glass (13) via the control unit (12). The electrochromic glass (13) in the protective mask is controlled in such a way that before the button (2) of the trigger device in the handle is pressed, the electrochromic glass (13) is energized and, therefore, transparent. After pressing the button (2), the circuit is triggered: the transmitter (9), the receiver (11), and the electrochromic glass control unit (12), whereby the electrochromic glass (13) is de-energized and becomes opaque. After the electrochromic glass (13) has become opaque, the continued movement of the rod (1) after an adjustable period of time switches on the IPL device (14), initiating a flash of light.The regulation of the time between the darkening of the glass (13) and the flash generated by the IPL device (the time delay between the closing of the A-A circuit and the B-B circuit) is determined by the stroke length of the rod (1), the gap of the contacts (7, 8) and the distance between the movable stop (5) and the fixed stop (4) of the rod (1).

[0024] The device operates as follows: the observer puts on a protective mask on his face and turns on the power of the device. At the same time, an electric current is supplied to the electrochromic glass (13) from the control unit (12), due to which the electrochromic glass (13) becomes transparent and does not interfere with the observation of the patient's skin. The observer takes the handpiece of the IPL device in his hand and presses the working element of the emitter of the handpiece to the treated area of ​​the skin (face). Next, the observer smoothly presses the button (2) of the rod (1) of the trigger device on the handpiece with his finger. The rod (1) with a fixed stop (3) compresses the spring (6). The compressed spring (6) presses the movable stop (5), which, sliding along the rod (1), closes the upper contact (7), which closes the electrical circuit (A-A) of the transmitter (9). The transmitter (9) sends a signal via a wireless communication line (10) to a receiver (11) located in the protective mask, which activates the control unit (12) of the electrochromic glass (13).The electrochromic glass (13) is de-energized and becomes opaque.

[0025] Further downward movement of the trigger rod (1), while the circuit (A-A) remains closed, closes the electrical contact (8) [circuit B-B] in the handpiece via the rod stop (4), causing a flash of light generated by the IPL device (14). This sequential control of the transparency of the protective glass and the flash of the IPL device protects the observer's vision from the intense light pulse.

[0026] After the flash of light, the observer releases the button (2) of the trigger device. The rod (1), under the action of the previously compressed spring (6), moves upward, initially breaking the circuit of the contact (8) controlling the IPL device (14). Further movement of the rod (1) to the initial position opens the contacts (7), the transmitter (9) in the handpiece is de-energized, and the receiver (10) inside the protective mask, in the absence of a signal from the transmitter (9), via the control unit (12), supplies voltage to the electrochromic glass (13), making it transparent again. The device is ready for the next operating cycle.

[0027] The technical result obtained by using the claimed invention consists in increasing the reliability of protection of the organ of vision and simplifying the work of the observer.

[0028] The claimed technical solution is new, has an inventive level, the significant differences of which ensure the achievement of the declared technical result and it is industrially applicable in various IPL devices.
