Description
Technical Field
The invention relates to an anti-scald casing, in particular to an anti-scald casing for an illumination skin-entering device and a device with the anti-scald casing.
Background
At present, there are many kinds of optical medical and optical related detection devices on the market, which perform medical and aesthetic, photoacoustic imaging, photodynamic therapy or medical examination through different light sources, but since the energy conversion efficiency cannot reach one hundred percent, the generation of heat energy is mostly accompanied when the electric energy is converted into the optical energy, and on the other hand, when the light beam passes through any interface, partial reflection and absorption are also caused, and another heat source is caused at the interface position. Because these devices are typically in direct contact with or in close proximity to the skin of the user or patient; even further, to avoid leaving a gap between the device and the skin of the subject, which would cause additional reflection, scattering or absorption of the illuminating beam, an index-matching optically transparent gel is additionally applied between the skin and the device, which would result in good optical contact. This also causes the heat emitted by the light emitting element and the heat generated at the interface location on the surface of the housing to cause accidental skin damage under the combined cumulative effect.
Generally, proteins begin to denature at about 42 degrees, human skin is composed of proteins, and if skin is exposed to a temperature of 60 ℃ for five minutes and a temperature of 70 ℃ for one minute, the proteins are immediately damaged, resulting in scalding. Even if the temperature is only 42 ℃, if the same part is continuously contacted for as long as 6 hours, scalding may be caused, and the scalding is called low-temperature scalding.
Generally, if a general burn is caused, the contact time between the skin and the high temperature source is short, and generally only a superficial scald is caused to the dermis. However, if the scald is caused by low temperature, the pain is not obvious because the temperature of the heat source is low, and the scald may develop into the scald of the deep dermis and each tissue layer under the skin under the long-term continuous action of the low heat source. Moreover, the pain of the low-temperature scald is not obvious, and the appearance of the low-temperature scald only appears to have the phenomena of desquamation, red swelling and the like, and seems not to be serious, but the low-temperature scald is characterized in that the wound depth is deep, the skin can be seriously ulcerated, and the low-temperature scald cannot heal for a long time.
Therefore, how to provide an anti-scald casing for an illumination skin-entering device can take away heat energy emitted by a light-emitting unit, avoid scalding human skin when using the device, and ensure the use safety is the purpose of the invention.

Detailed Description
The invention is further illustrated with reference to the following figures and specific examples. These examples are to be construed as merely illustrative and not limitative of the remainder of the disclosure in any way whatsoever. After reading the description of the invention, one skilled in the art can make various changes and modifications to the invention, and such equivalent changes and modifications also fall into the scope of the invention defined by the claims.
First preferred embodiment
As shown in fig. 1, in the light irradiation skin device with an anti-scald housing according to the first preferred embodiment of the present invention, the light irradiation skin device 1 is exemplified as a household phototherapy device, which induces fibroblasts in the dermis layer by using red light with a wavelength of 630 nm, for example, to cause the collagen fibers in the dermis to change, thereby activating the skin of the user. The phototherapy device is closely attached to the skin 9 of the subject, and for convenience of illustration, the skin 9 is identified by the structural numbers epidermis 90, dermis 92 and subcutaneous tissue 94, and the muscle 8 is located below the skin 9.
The exterior of the phototherapy device in this embodiment is an anti-scald casing 2, which mainly includes a hollow body 22 and a light-transmitting portion 24, and an accommodating space 20 is surrounded by the hollow body 22 and the light-transmitting portion 24. The circuit board 12 and the insulating cooling medium 14 are disposed in the accommodating space 20, the light emitting unit 10 is disposed on the circuit board 12, and since the light beam emitted by the light emitting unit 10 in this embodiment is mainly infrared light, the material of the light-transmitting portion 24 in this embodiment is a ceramic material that can allow infrared light to pass through, rather than ordinary glass. In the present embodiment, the light emitting unit is exemplified by a single red led, and a lens assembly 19 is additionally disposed in the main light emitting direction 100 of the led to change the divergence condition of the light beam, so as to achieve the focusing, beam expanding or parallel light effects according to the application requirements.
The light emitting unit 10 and the circuit board 12 are soaked in the insulating refrigerant 14, because the electrical conductivity of the refrigerant 14 is quite low, the light emitting unit 10 and the circuit board 12 cannot cause short circuit due to the refrigerant 14, and the refrigerant 14 can absorb heat energy emitted by the light emitting unit 10, the circuit board 12 and other circuit components and heat energy absorbed or converted by the light-transmitting portion 24 by direct contact, in order to ensure the safety of an illuminated person, the refrigerant is selected to be a material with a boiling point lower than, for example, 42 ℃, and is defined as a safe boiling point, when the insulating refrigerant 14 absorbs heat energy and reaches the safe boiling point, the received heat energy is converted into latent heat, so that the liquid refrigerant is changed into a gas state, and moves upwards due to buoyancy. By means of the conduction and convection of the cooling medium 14, it is ensured that the position contacting the irradiated person will not reach the scalding temperature.
When the phototherapy device is held by the user's hand in the present embodiment during the process of irradiating each portion for a fixed period of time, since the accommodating space of the phototherapy device of the present invention is not pumped to a low pressure or vacuum state as in a common heat pipe, but takes a normal pressure state of, for example, an atmospheric pressure, and the phototherapy device does not have a specific fixed upper and lower position, but is constantly switched in angle and position, once the vaporized refrigerant is shielded in front of the light emitting unit, on one hand, the efficiency of absorbing heat energy is greatly reduced, and on the other hand, the main light emitting angle is shielded by bubbles, which causes the traveling direction of the light beam to be deflected beyond expectation. Therefore, an additional gas accommodating cavity 220 is formed on the hollow body 22 of the scald preventing housing of the present invention, in the present embodiment, the hollow body 22 mainly extends along the main light emitting direction 100 of the light emitting unit and is substantially cylindrical, a portion of the hollow body 22 forming the gas accommodating cavity 220 is a doughnut shape expanding outward along a radial direction relative to the main light emitting direction 100, and a portion of the hollow body 22 located above the drawing is a heat conducting portion 222, which is illustrated as a heat dissipating fin.
It can be easily understood that, as shown in fig. 2, when a user holds the cylindrical portion of the hollow body 22 in a transverse manner to perform phototherapy, the light emitting unit and other heat generating components on the circuit board will gradually generate heat, the refrigerant 14 directly contacted with the light emitting unit will absorb the heat energy to gradually increase the temperature, when reaching a safe boiling point, the absorbed heat energy will be converted into latent heat, and the refrigerant will be gradually vaporized, because the doughnut-shaped gas accommodating cavity 220 is located in the radial extending direction of the main light emitting direction 100 and is in conductive connection with the accommodating space 20 at three hundred sixty degrees in the radial direction, when the refrigerant is converted into a gaseous state from a large amount of liquid state, at least part of the refrigerant will enter the gas accommodating cavity 220 due to the gravity and the buoyancy, and the gaseous refrigerant in the accommodating space 20 will be reduced.
Since the air receiving cavity 220 is adjacent to the heat dissipating fins, when the external air contacts the heat dissipating fins and takes away the heat energy carried by the gaseous refrigerant, the refrigerant will gradually return to the liquid state and fall back due to gravity. Even if the heat generated by the light emitting unit is greater than the heat dissipated by the outside air, which causes the gaseous refrigerant to gradually increase, and the occupied volume to gradually increase, and the internal pressure of the accommodating space to increase, in this embodiment, the circuit board is provided with the timing unit, and the power supply is actively cut off after the circuit board is irradiated for a suitable time, for example, 15 minutes. In addition to preventing the phototherapy device from overheating, the phototherapy device also limits the usage time of the user to prevent the user from being over-illuminated and damaging the cells which are only to be activated.
In the embodiment, the heat conducting portion 222 is a fin-shaped structure, so as to increase the contact area between the heat conducting portion 222 and the outside air, thereby achieving the heat dissipation effect, and the heat conducting portion 222 is made of metal with higher heat conductivity coefficient, and relatively, the hollow body 22 is used as the cylindrical portion of the holding portion, and is made of plastic with low heat conductivity coefficient, so that the holding portion cannot be held due to overheating when the person operates the light irradiation skin device 1; the light-transmitting portion 24 contacting the skin is made of a ceramic material in this embodiment, and has a thermal conductivity slightly higher than that of the grip portion, but still much lower than that of the heat-conducting portion 222 made of a metal material. Therefore, the heat generated inside the scald preventing machine casing 2 is mainly dissipated through the heat conducting portion 222.
Second preferred embodiment
Of course, as those skilled in the art can readily understand, the light irradiation skin device with the scald preventing housing of the present invention is not limited to contacting the skin of the user with the light-permeable portion. As shown in fig. 3 and 4, the illumination skin device 3 according to the second preferred embodiment of the present invention is explained as a neonatal jaundice (jaundice) detection/phototherapy device. Neonatal jaundice is mainly due to a yellow or green skin and sclera due to a high bilirubin (bilirubin) level, which has a main absorption spectrum of 440nm, which is shifted by tens of nm depending on the oxygen-containing and oxygen-deficient state of bilirubin, so that some patients with light emitting devices can be treated with light such as near ultraviolet light or bluish violet light with a wavelength of 460 to 490 nm. The parts that are the same as the previous example are not described again in this example, and only the differences are described.
The light irradiation device 3 in this embodiment also includes an anti-scald casing 4, and a circuit board 32 and an insulating coolant 34 disposed in the anti-scald casing 4, wherein the circuit board 32 is provided with a plurality of LEDs as light emitting units 30, for example, having main light emitting wavelengths of 440nm, 460nm, and 490nm, respectively. The scald preventing machine case 4 also includes a hollow body 42 and a light-transmitting portion 44, and the hollow body 42 and the light-transmitting portion 44 jointly surround and combine to form the closed accommodating space 40. In order to promote the flow of the liquid insulating refrigerant 34 in the accommodating space 40, at least one pump 38 is further disposed in the accommodating space 40, and the pump 38 achieves the effect of circulating the refrigerant 34 through the rotation of the inner impeller. The light emitting unit 30 irradiates toward the light transmitting portion 44 along the same main light emitting direction 300, and in the present embodiment, the light transmitting portion 44 further has a protruding curved surface 442 in the direction toward the accommodating space 40, so that even if the light transmitting portion 44 is operated in the upward direction, the vaporized refrigerant is not easily accumulated in the central portion inside the light transmitting portion 44 to obstruct the light beam emitting in the main light emitting direction 300.
In the present embodiment, the hollow body 42 is formed by three-dimensionally printing, for example, a metal material, and thus, as shown in fig. 4, for example, six cavities are additionally formed as the gas accommodating chambers 420 at the upper portion of the skin irradiation device 3, and if the main light emitting direction 300 is taken as the axial direction, each gas accommodating chamber 420 is radially distributed in the radial direction forming an angle of about ninety degrees with the axial direction, so that no matter how the jaundice detection/phototherapy device is tilted, an appropriate gas accommodating chamber 420 is provided to accommodate the vaporized coolant 34. Further, since the hollow body 42 is thinner at the portion of the shell where the gas accommodating chamber 420 is formed, the thermal conductivity of the portion is better, namely, the heat conducting portion 422 in the present embodiment, and in the present embodiment, a detachable cold source 48 is further disposed at the position of the hollow body 42 corresponding to the heat conducting portion 422, which is, for example, an ice castle capable of being stored in an ice warehouse.
Since the irradiation object in this embodiment may be an infant, the part contacting the skin may be the hollow body 42 protruding from the front edge of the light-transmitting portion 44 instead of the light-transmitting portion 44, and considering that the infant cannot express the feeling of temperature, the ice castle in this embodiment further has a temperature-sensing color-changing region (not numbered) at the position where the holding portion 46 is formed, so that after the detachable cold source 48 is mounted to the heat-conducting portion 422, the detachable cold source is attached to the heat-conducting portion 422 to absorb the internal heat energy, so that the heat energy emitted by the light-emitting unit 30 can be guided to the outside more quickly, and when the temperature of the ice castle gradually increases and loses the cooling effect, the operator can easily observe the color change to terminate the operation.
Third preferred embodiment
As shown in fig. 5, the skin-illuminating device with scald-preventing housing according to the third preferred embodiment of the present invention has the same technical features as the above embodiments, and the skin-illuminating device 5 is exemplified by a photoacoustic imaging apparatus, so that on the circuit board 52, in addition to the light-emitting unit 50, a receiving unit 522 is further included, when the main beam of the pulsed laser emitted by the light-emitting unit 50 is emitted into the skin to reach the imaging region, the cell corresponding to the predetermined target region absorbs the main beam and converts it into heat energy, and the nearby tissue is thermoelastically expanded, so as to form a broadband ultrasonic wave emission, and the acoustic wave with the predetermined frequency can be received by the receiving unit 522 to form photoacoustic imaging or photoacoustic imaging. In order to avoid unnecessary air gaps blocking incident light or returning sound signals, a glue 70 with matched optical refractive index and sound propagation rate is additionally coated between the light-transmitting portion 64 and the skin. The receiving unit 522 may be not only the above-mentioned component capable of receiving the sound wave with a specific range of frequency, but also a component capable of receiving the light signal or having a function of sensing temperature, so that the light-irradiating skin device 5 can adjust the light-emitting power of the light-emitting unit 50 according to the light signal or the temperature change, or perform subsequent analysis or processing according to the values of the light signal or the temperature, etc.
In this embodiment, the hollow body 62 has an inner shell 624 and an outer shell 622 that are double-layered, and a plurality of micro air holes are further formed on the inner shell 624, so that a large air accommodating cavity 620 is formed between the inner shell 624 and the outer shell 622, and no matter how the arrangement position is when the light enters the skin device for operation, once the refrigerant is vaporized from the liquid state, the refrigerant can enter the air accommodating cavity 620 between the inner shell 624 and the outer shell 622 from the micro air holes due to the action of gravity and buoyancy, and waits for being condensed to return to the liquid state.
In summary, the anti-scald casing for the illumination skin-entering apparatus and the apparatus with the anti-scald casing provided by the invention can effectively prevent the skin from being scalded by the light-emitting unit, so that the temperature of the skin-contacting portion of the illumination skin-entering apparatus is lower than the dangerous temperature of low-temperature scalding, the apparatus can be used by the person to be irradiated more safely, and the time for the person to be irradiated to use the apparatus once can be prolonged.
