背景技术Background technique
FDA把安全放在第一位；如果你的设备存在安全隐患，他们是不会批准的。公司也希望安全；只有安全的产品才能保证成功的商业化。我们早期的产品电子止痒器(https://www.ItchStopper.com)使用热量来消除皮肤瘙痒已经非常成功。热量必须高到足以引起皮肤烧伤的边缘。所以如果没有严格的控制，这是不安全的。The FDA puts safety first; they won't approve your device if it poses a safety hazard. Companies also want safety; only safe products can guarantee successful commercialization. Our early product, the Electronic Itch Stopper (https://www.ItchStopper.com), which uses heat to relieve itchy skin, has been very successful. The heat must be high enough to cause the skin to burn to the brim. So it's not safe without strict controls.
如果热量未达到灼热的程度，它就不会对瘙痒起作用。为什么人们还没有发现吹风机对皮肤瘙痒有效？其中一个原因是，只有当吹风机离皮肤近到引起灼热的感觉时才会起作用。当人们有这种感觉时，他们会很快把吹风机从皮肤上移开。然而，为了消除瘙痒，你需要在这种灼热的感觉下继续加热1-7秒。If the heat isn't to the point of burning, it won't work on the itching. Why haven't people found hair dryers to be effective for itchy skin? One reason for this is that the blow dryer only works when it's brought close enough to the skin to cause a burning sensation. When people feel this way, they quickly remove the blow dryer from their skin. However, in order to get rid of the itching, you need to continue heating under this burning sensation for 1-7 seconds.
到目前为止，没有什么对湿疹、毒藤/毒橡树病、疱疹、荨麻疹、过敏、唇疱疹、癌症、肾脏或肝脏衰竭等引起的大面积皮肤瘙痒有效。可的松软膏可以在一定程度上起作用，但它们不能立即止痒，而且你不能使用超过14天，否则会对你的肾上腺造成永久性损伤。你可以在那些止痒产品上找到这样的警告，你需要停止一个月左右才能再次使用它们。So far, nothing is effective for large areas of itchy skin caused by eczema, poison ivy/poison oak disease, herpes, hives, allergies, cold sores, cancer, kidney or liver failure, etc. Cortisone ointments can help to a degree, but they don't relieve the itching immediately, and you can't use them for more than 14 days or you can cause permanent damage to your adrenal glands. You can find such warnings on those anti-itch products that you need to stop for a month or so before using them again.
许多人染上了毒藤/毒橡树病。痒得难以忍受，会持续大约三个月。这对患者来说是一次可怕的经历。作为一名医生，我也知道很多患者只是把皮肤抓挠到流血。大约50％的人患有疱疹，其中一些人还会有难以忍受的瘙痒。在美国，大约10％的人因皮肤瘙痒急需专业医疗帮助。Many people get poison ivy/poison oak disease. The itching is excruciating and lasts for about three months. This is a frightening experience for the patient. As a doctor, I also know many patients who just scratch their skin until it bleeds. About 50 percent of people have herpes, and some of them also experience excruciating itching. About 10 percent of people in the United States are in urgent need of professional medical help for itchy skin.
二十年前，FDA批准了我们的医疗器械，电子止痒器(https://www.ItchStopper.com)，我们已经卖出了很多，拯救了无数皮肤瘙痒患者。一些患者说止痒器救了他们的命，另一些人说他们完全依赖它。我们为我们所做的一切感到自豪。Twenty years ago, the FDA approved our medical device, the Electronic ItchStopper (https://www.ItchStopper.com), and we have sold a lot and saved countless patients with itchy skin. Some patients say the itch reliever saved their life, others say they are totally dependent on it. We take pride in everything we do.
15年前，我们把止痒器的专利卖给了一家美国公司。那家公司的祛痘产品获得了FDA的批准。虽然止痒器对痤疮有效，但它的成功率只有70％左右，由于较高的退货率，这并不能保证商业上的成功。然而，对于皮肤瘙痒，这是一个确定的事情。治疗皮肤瘙痒的成功率为100％。15 years ago, we sold the patent for an anti-itch device to an American company. That company's acne products are FDA-approved. While the itch reliever is effective for acne, it only has a success rate of around 70%, which does not guarantee commercial success due to the high return rate. However, for itchy skin, it's a sure thing. The success rate of treating itchy skin is 100%.
止痒器有一些局限性。它使用热板加热皮肤，只能治疗非常局部的皮肤瘙痒。它对大面积的皮肤瘙痒不起作用，然而，只有这样大面积的皮肤瘙痒最需要治疗。与止痒器相关的另一个问题是，它只适用于平坦的皮肤表面，而不是曲线的皮肤表面。第三个问题是，它对起泡的皮肤不好，但大多数严重的患者都有水泡。许多患者要求我们做更大更弯的止痒器。为了满足这种未被满足的需求，我们发明了止痒吹风机，用于治疗皮肤瘙痒和大多数皮肤病。Antipruritic devices have some limitations. It uses a hot plate to heat the skin and only treats very localized itchy skin. It does not work on large areas of itchy skin, however, only such large areas of itchy skin need treatment most. Another problem associated with antipruritics is that they only work on flat skin surfaces, not curved ones. The third problem is that it's not good for blistered skin, but most severe patients have blisters. Many patients have asked us to make larger and more curved antipruritic devices. To fill this unmet need, we created the Anti-Itch Hair Dryer to treat itchy skin and most skin conditions.
止痒吹风机使用热空气作为介质来传递热量。它与吹风机非常相似，但会做一些改进。我们的改进将使吹风机安全有效地治疗皮肤瘙痒。止痒吹风机可以覆盖大面积，可以用于曲线区域，也可以用于起泡的皮肤。它对治疗全身皮肤瘙痒有效。瘙痒吹风机是解决各种皮肤瘙痒问题的答案。Anti-itch hair dryers use hot air as a medium to transfer heat. It's very similar to a hair dryer, but with a few improvements. Our improvements will allow hair dryers to safely and effectively treat itchy skin. Anti-itch blow dryers can cover large areas and can be used on curvilinear areas or on blistered skin. It is effective in treating itchy skin all over the body. Itchy hair dryers are the answer to all kinds of itchy skin problems.
止痒吹风机和吹风机相比，虽然你会有一些场合可以把它们替换使用，但吹风机在治疗皮肤瘙痒方面大多不起作用。首先，当吹风机太靠近皮肤时，它会对皮肤造成损伤。其次，当你把它放到治疗瘙痒的距离时，你会感觉到灼热的感觉，大多数人会因为灼热感觉而直接把它挪开。他们只是没有加热皮肤足够的时间来治愈瘙痒。第三，当吹风机离皮肤太远时，它会加重瘙痒，因为它只会使皮肤变热。加热皮肤至没有达到灼热程度时会导致局部血液流动增加，从而加剧炎症；它还会导致皮肤肥大细胞释放更多的组胺，从而加剧瘙痒。这就是为什么人们在天气变热的时候会感到更痒。Anti-itch hair dryers are mostly ineffective at treating itchy skin, although there are occasions when you can substitute them. First of all, when the hair dryer is too close to the skin, it can cause damage to the skin. Secondly, when you put it at a distance to treat itching, you will feel a burning sensation, and most people will simply remove it because of the burning sensation. They just don't heat the skin long enough to heal the itching. Third, when the blow dryer is held too far from the skin, it can aggravate the itching because it just heats up the skin. Heating the skin to the point of not burning causes increased local blood flow, which increases inflammation; it also causes skin mast cells to release more histamine, which increases itching. That's why people itch more when the weather gets hotter.
一个抗原(就像蚊子注射的抗原)，首先会与两种抗体结合形成一个修饰物，引发钙通道中的钙潮，然后，使皮肤肥大细胞脱粒组胺，导致瘙痒，皮疹，皮肤肿块，炎症和大多数皮肤病(比如痤疮)。加热皮肤只会加速这个过程，从而引起更严重的瘙痒。然而，使皮肤灼热就不会。它会停止这个过程。根据一份报告，它会导致抗原与两种以上的抗体结合，从而形成一个不会引发钙潮的多聚体；同时，使皮肤灼热会使一些钙通道脱粒蛋白变性，从而止痒。One antigen (like the one injected by a mosquito), first binds to two antibodies to form a modifier, triggering a calcium surge in calcium channels, which then degranulates the skin mast cells with histamine, leading to itching, rashes, skin bumps, inflammation and most skin diseases (such as acne). Heating the skin will only speed up the process, causing more severe itching. Burning the skin, however, does not. It stops the process. According to one report, it causes the antigen to bind to two or more antibodies to form a multimer that does not trigger a calcium surge; meanwhile, burning the skin denatures some calcium channel degranulation proteins, which relieves the itching.
我们想要的是在未烧伤皮肤的情况下使皮肤灼热。What we want is to burn the skin without burning it.
我们的皮肤能很好地抵御灼热。在这个范围内，我们会感到刺痛、麻刺感、滚烫、轻微的疼痛或轻微的灼烧感，如果控制得很好，能在短时间内保持这种感觉，我们就能消除瘙痒。这个有效温度范围很窄。如果没有控制的方法，我们要么会加重瘙痒，要么会使皮肤烧伤。在烧伤发生之前，这些感觉会变得难以忍受，如果我们把加热温度控制在高到可以消除瘙痒，但又低到让我们有时间远离热源的程度，我们就会安全。Our skin resists the heat very well. In this range we experience a tingling, tingling, burning, mild pain or slight burning sensation, and if well controlled and maintained for a short period of time, we can get rid of the itching. This effective temperature range is very narrow. Without a way to control it, we either end up with aggravated itching or skin burns. These sensations can become unbearable before the burn occurs, and if we keep the heat high enough to get rid of the itching, but low enough to give us time away from the heat, we'll be safe.
具体实施方式Detailed ways
止痒吹风机可能包含了吹风机的所有元件。但是，我们会移除所有可能会对皮肤瘙痒的治疗产生负面影响的元件。此外，我们的止痒吹风机使用热空气加热皮肤，而不是头发。我们将对吹风机进行改造，将热空气设置到一定的温度，An anti-itch hair dryer may contain all the elements of a hair dryer. However, we remove all elements that may negatively affect the treatment of itchy skin. Plus, our anti-itch blow dryer uses hot air to heat the skin, not the hair. We will modify the hair dryer to set the hot air to a certain temperature,
这样它可以以一定的空气流速和以皮肤与出风口之间的一定距离，将皮肤加热到对特定的瘙痒具有治疗作用的温度。这意味着，在一定的空气流速和一定的距离下，我们会选择一种发热丝容量，它可以保持热空气的热度，使皮肤快速加热到有效温度，例如43℃或52℃，并且持续特定的时间，例如3秒，这样它可以停止皮肤瘙痒，但不会引起烧伤。In this way it can heat the skin to a therapeutic temperature for a specific itching at a certain air velocity and at a certain distance between the skin and the air outlet. That means, at a certain air flow rate and a certain distance, we will choose a heating wire capacity that can keep the heat of the hot air and heat the skin to an effective temperature quickly, such as 43°C or 52°C, and for a specific time, such as 3 seconds, so that it can stop the itching of the skin but not cause burns.
为了让用户知道他们必须把止痒吹风机的热空气出口离皮肤多远，我们可以简单地在设备上或用户手册中设置一个标签，比如“1英寸”；我们也可以附带一根棍子(图1)，这意味着一根棍子可以从止痒吹风机出风口向皮肤伸出。棍子的一端附着在出风口上，棍子的另一端指向皮肤。当用户将棍子放在皮肤上或靠近皮肤时，用户知道预定的距离。棍子的长度可以调节，这意味着它可以拉得更长或缩得更短。我们可以在每一个不同的长度设置标签，如儿童、成人腿部、成人胃部、比正常皮肤厚等，这样当用户调整长度时，他们就可以通过标签来判断这是否能针对他们瘙痒的情况。To let the user know how far away from the skin they must place the hot air outlet of the anti-itch hair dryer, we can simply put a label on the device or in the user manual, such as "1 inch"; One end of the stick is attached to the air outlet, and the other end of the stick points to the skin. When the user places the stick on or close to the skin, the user knows the predetermined distance. The length of the stick is adjustable, which means it can be stretched longer or shortened. We can set labels in each different length, such as children, adult legs, adult stomach, thicker than normal skin, etc., so that when the user adjusts the length, they can use the label to judge whether this is suitable for their itching.
我们可以将红外线，激光或任何其他距离测量器纳入止痒吹风机来代替物理上的棍子，用于远程测量距离，并且，在这种情况下，我们使用数字信号手段(如LED屏幕)来告诉用户将止痒吹风机离皮肤近些或者远一些，或者已经位于正确距离。Instead of a physical stick, we can incorporate infrared, laser, or any other distance measurer into the anti-itch hair dryer for remote measurement of distance, and, in this case, we use digital signal means (such as LED screen) to tell the user to bring the anti-itch hair dryer closer or farther away from the skin, or already at the correct distance.
除了LED屏幕，我们也可以使用任何其他方式来显示距离设置，并告知用户距离是否正确。Besides the LED screen, we can also use any other way to display the distance setting and inform the user if the distance is correct or not.
如图1所示，该棍子可以是一个温度计，还具有第二个功能，即感知皮肤附近热空气的温度或直接感知皮肤的温度。当热空气或皮肤达到所需的温度，并在所需的时间内，传感器与恒温器一起工作，降低加热量，以控制或降低热空气的温度，降低热空气的体积，使皮肤保持在一个安全但起作用的温度，甚至间歇性地关闭设备，以避免烧伤皮肤。或者，也可以像人们使用温度计一样，把水银放在棍子里，只是尖端含有更多的水银。温度使水银消耗，当水银达到一定长度时，它会以类似于我们在早期专利中描述的方式关闭电源(专利号:US 7537605B2中的图3)。As shown in Figure 1, the stick can be a thermometer that also has a second function of sensing the temperature of hot air near the skin or directly sensing the temperature of the skin. When the hot air or skin reaches the desired temperature, and for the desired amount of time, the sensor works with the thermostat to reduce the heat to control or reduce the temperature of the hot air, reduce the volume of the hot air to keep the skin at a safe but functional temperature, and even shut off the device intermittently to avoid burning the skin. Alternatively, the mercury can be put in a stick like people use a thermometer, only the tip contains more mercury. The temperature depletes the mercury and when it reaches a certain length it shuts off the power in a manner similar to what we described in our earlier patent (patent number: Figure 3 in US 7537605B2).
热电偶可以更好地感知温度并反馈给恒温器。红外线和任何其他非接触式和远程温度传感器也可以做得更好。我们应该把这些加入我们的止痒吹风机。为了了解如何使用热电偶或数字温度传感器，技术人员可以参考炉式烤箱、家庭加热系统恒温器或任何其他机器，例如红外体温传感器。Thermocouples provide better temperature sensing and feedback to the thermostat. Infrared and any other non-contact and remote temperature sensors can do a better job too. We should add these to our anti-itch hair dryer. To learn how to use a thermocouple or digital temperature sensor, a technician can refer to a furnace oven, home heating system thermostat, or any other machine such as an infrared body temperature sensor.
我们需要加入一个温度选择器，以便人们可以设定他们想要的治疗类型。温度选择器可以与恒温器一起工作，相应地，还可以与温度传感器一起工作，也可以与距离测量器一起工作。可以开发软件，使恒温器像机器人恒温器一样智能。We need to include a temperature selector so people can set the type of treatment they want. The temperature selector can work with a thermostat and, correspondingly, with a temperature sensor or with a distance measurer. Software could be developed to make thermostats as smart as robotic thermostats.
不同的皮肤瘙痒情况可能需要不同的温度。Different itchy skin conditions may require different temperatures.
比如我们之前的止痒器，加热垫在治疗儿童皮肤瘙痒时约为49℃，在治疗成人全身皮肤瘙痒时约为51℃，在治疗成人四肢皮肤瘙痒时约为53℃，对于皮肤变得比正常情况厚的慢性皮肤瘙痒患者，温度更高，如57℃，对于更严重的情况，温度为62℃。例如，当患者将模式设置为设置1或成人的腿部时，加热垫的温度可能在53℃左右。For example, in our previous antipruritic device, the heating pad is about 49°C when treating itchy skin in children, about 51°C when treating itchy skin in adults, about 53°C when treating itchy skin in adults' extremities, and for patients with chronic skin itching whose skin becomes thicker than normal, the temperature is higher, such as 57°C, and for more severe cases, the temperature is 62°C. For example, when the patient has the mode set to setting 1 or an adult's legs, the temperature of the heating pad may be around 53°C.
止痒吹风机也可以做同样的事情，对应不同的治疗方法吹出不同的温度。由于止痒吹风机不接触皮肤，温度可能会稍高，例如比止痒器高2℃。我们将做更详细的研究，使每一个使用热空气的特定治疗方法获得更准确的温度。Anti-itch hair dryers can do the same thing, blowing out different temperatures for different treatments. Since the anti-itch hair dryer does not touch the skin, the temperature may be slightly higher, for example, 2°C higher than the anti-itch device. We will be doing more detailed research to get more accurate temperatures for each specific treatment using hot air.
皮肤温度不同于上述加热垫或热空气温度，止痒吹风机可以直接感知皮肤温度；我们可以让它把皮肤加热到特定温度。我们将进行更广泛的测试，但目前，对于每一个特定的治疗方法，我们打算将皮肤加热到比我们早期的止痒器提供的温度低约2-5℃。Skin temperature Unlike the heating pad or hot air temperature mentioned above, the anti-itch hair dryer can directly sense the skin temperature; we can let it heat the skin to a specific temperature. We will be testing more extensively, but for now, for each specific treatment, we intend to heat the skin to a temperature approximately 2-5°C lower than that provided by our earlier antipruritic devices.
皮肤的温度是有起作用的范围的。如上述，我们说对于成人四肢皮肤瘙痒，我们的加热垫提供53℃，但对于皮肤，起作用的范围可为47-53℃，甚至更低。Skin temperature has a range of effects. As mentioned above, we say that for itchy skin on the extremities of adults, our heating pad provides 53°C, but for the skin, the effective range can be 47-53°C, or even lower.
如果我们只合并一个温度传感器来感知皮肤温度，无论这个温度传感器是远程传感器还是接触式传感器，那么从出风口到皮肤的距离就变得不那么重要了。所以在这种情况下，我们可以不需要加入距离传感器。我们可以简单地建议用户把止痒吹风机置于大约1英寸或任何其他距离。我们可以简单地使用一个普通的吹风机，让温度传感器告诉恒温器皮肤温度。当皮肤温度达到用户设定的特定情况时，恒温器可以降低或关闭加热元件和/或风扇的电源，从而降低热空气的温度甚至停止加热，当皮肤温度低于所需温度时，恒温器可以反过来间歇性地打开电源，这样使皮肤温度保持在起作用的作用范围内。If we only incorporate a temperature sensor to sense the skin temperature, whether this temperature sensor is a remote sensor or a contact sensor, then the distance from the air outlet to the skin becomes less important. So in this case, we don't need to add a distance sensor. We could simply advise the user to place the anti-itch blow dryer about 1 inch or any other distance. We could simply use a normal hair dryer and have the temperature sensor tell the thermostat the skin temperature. When the skin temperature reaches a certain level set by the user, the thermostat can reduce or turn off the power to the heating element and/or fan, thereby reducing the temperature of the hot air or even stopping the heating.
虽然我们更希望皮肤温度保持在42-60℃，但热空气的温度可能更高。任何温度在42℃到1000℃之间的热空气都可以使用。在单次治疗中，加热皮肤区域的持续时间可以是2-7秒，也可以使用任何其他持续时间，例如1-150秒。While we would prefer to maintain a skin temperature of 42-60°C, the hot air can be even hotter. Any hot air with a temperature between 42°C and 1000°C can be used. The duration of heating the skin area may be 2-7 seconds in a single treatment, any other duration may be used, for example 1-150 seconds.
当我们可以测量皮肤温度时，热空气温度就变得不那么重要了；我们可以使用高热空气温度。租用Y260SR型烘干机，型号259Y、125V交流电、60Hz、1875W，由康奈尔公司生产，有三种设置，用于控制三种不同温度水平的热空气温度。我们可以移除这些设置，并保持热空气温度只有高水平，然后合并一个1R远程温度传感器(远程温度计)。我们可以增加三个设置来控制皮肤温度。当温度计显示皮肤温度达到所需温度(某一特定治疗的起作用的范围)时，它会指示恒温器降低或关闭加热元件的电源，以降低热空气的温度，甚至关闭风扇以停止加热。例如，当温度计显示皮肤温度达到治疗儿童所需的温度时，它会指示恒温器降低或关闭加热丝或风扇的电源来降低或停止加热。当温度计显示皮肤温度达到治疗成人腿部所需温度时，止痒吹风机执行同样操作。When we can measure skin temperature, hot air temperature becomes less important; we can use high hot air temperature. A rented model Y260SR dryer, model 259Y, 125VAC, 60Hz, 1875W, manufactured by Cornell, has three settings to control the temperature of the hot air at three different temperature levels. We can remove these settings and keep the hot air temperature only high level, then incorporate a 1R remote temperature sensor (remote thermometer). We can add three settings to control the skin temperature. When the thermometer shows that the skin temperature has reached the desired temperature (the range in which a particular treatment works), it instructs the thermostat to lower or turn off the power to the heating element to reduce the temperature of the hot air, or even turn off the fan to stop the heat. For example, when the thermometer shows that the skin temperature has reached the temperature needed to treat a child, it instructs the thermostat to reduce or turn off the power to the heating wire or fan to reduce or stop the heat. When the thermometer shows that the skin temperature is the temperature required to treat an adult's leg, the Anti-Itch Hair Dryer does the same.
在设计止痒吹风机时，技术人员可以参考我们家庭数字加热系统或数字远程体温温度计中的恒温器。它应该清楚地展示温度传感器如何指示恒温器关闭和打开加热系统，在我们的例子中，展示了当皮肤温度达到所需温度设置时，恒温器如何关闭和打开我们的加热元件或风扇。如果我们只是想降低加热元件的强度，我们可以以同样的方式做到这一点，但只是通过将电源切换到欧姆更大电阻来降低加热元件的电源供应，这样就可以减少通过加热元件的电流。反之亦然。When designing an anti-itch hair dryer, technicians can refer to the thermostats in our home digital heating systems or digital remote body temperature thermometers. It should clearly show how the temperature sensor instructs the thermostat to turn off and on the heating system, in our case how the thermostat turns off and on our heating element or fan when the skin temperature reaches the desired temperature setting. If we just want to reduce the intensity of the heating element, we can do it in the same way, but just reduce the power supply to the heating element by switching the power supply to a larger resistance in ohms, so that less current will be drawn through the heating element. vice versa.
从普通吹风机吹出来的热空气加热不均匀或混合不均匀。因为周围有加热丝但中心没有，因此周围会更热，但中心没有那么热。我们要做的是在中心添加一些加热元件，比如把加热丝弄乱，这样包括中心在内的每个地方都有加热丝。我们也可以改变热空气的通道，比如做一个或几个转弯，让空气混合后再出来。The hot air from a regular hair dryer doesn't heat or mix evenly. Because there are heating wires around but not in the center, it will be hotter around but not as hot in the center. What we're going to do is add some heating elements to the center, like messing up the heating wires so there are heating wires everywhere including the center. We can also change the passage of hot air, such as making one or several turns, allowing the air to mix and then come out.
普通吹风机的出风口对于局部瘙痒(比如蚊子叮咬)来说太大了。我们希望出风口是可调节的，这样，用户就可以根据瘙痒的面积大小来调整出风口的大小。他们可以用最大的出风口来治疗很大面积的局部瘙痒，这样他们甚至可以覆盖整个身体，相对较小的出风口来治疗大面积的局部瘙痒，最小的出风口来治疗如昆虫叮咬的局部瘙痒。The air outlet of ordinary hair dryers is too large for localized itching, such as mosquito bites. We hope that the air outlet is adjustable, so that users can adjust the size of the air outlet according to the size of the itching area. They can treat large areas of localized itching with the largest air outlet so that they can even cover the entire body, relatively small air outlets for large areas of localized itching, and the smallest air outlets for localized itching such as insect bites.
最简单的方法是在出风口处贴上一块不燃布套筒，就像衬衫袖子一样。所述套筒的一端与所述止痒吹风机的出风口相连，另一端自由打开。套筒开口的自由端可以有一根像腰带一样的圆绳，人们可以通过收紧或放松圆绳来调节套筒的开口。这将允许用户控制空气的宽度，从而治疗不同面积大小的瘙痒。The easiest way to do this is to attach a non-combustible cloth sleeve to the air outlet, like a shirt sleeve. One end of the sleeve is connected to the air outlet of the anti-itch hair dryer, and the other end is freely open. The free end of the sleeve opening can have a round cord like a belt, and one can adjust the opening of the sleeve by tightening or loosening the round cord. This will allow the user to control the width of the air, thus treating itches of different sizes.
我们也可以做不同尺寸的开口。不同尺寸的开口的一端可以很容易地连接到止痒吹风机的出风口，另一端尺寸不同。当用户想要治疗大面积瘙痒时，他们会附上一个大出风口。当遇到小区域瘙痒时，它们会附上较小的出风口。We can also do openings of different sizes. One end with different size openings can be easily connected to the air outlet of the anti-itch hair dryer, and the other end is a different size. When users want to treat large areas of itching, they attach a large air outlet. They attach smaller air outlets when experiencing itching in small areas.
其他领域的所有其他技术都可以使用。就像使用传统相机一样，你可以通过简单地转动相机顶端的控制器来调整大小或焦距，而连接在出风口上的许多不同的金属片可以或多或少地重叠，从而缩小或扩大出风口。All other techniques from other fields can be used. Just like with a traditional camera, you can adjust the size or focus by simply turning the controls on the top of the camera, and the many different pieces of metal attached to the vent can overlap more or less to shrink or expand the vent.
可以用电池或者厂用主电源作为电源。Battery or factory mains power can be used as the power source.
在另一个实施例中，我们可以简单地在设备上放一个标签或在用户手册中放一个注意事项。标签或注意事项将要求患者将止痒吹风机放置在离皮肤足够近的地方，例如只有1/2英寸到1英寸，以便止痒吹风机可以将皮肤加热到有效温度。标签/注意事项还可以告诉患者，当他们已经感到刺痛、麻刺感、轻微疼痛、灼热和轻微灼烧感时，他们必须继续加热皮肤一段时间，例如1-7秒。In another embodiment, we could simply put a label on the device or a notice in the user manual. The label or precaution will ask the patient to place the anti-itch blower close enough to the skin, such as only 1/2 inch to 1 inch, so that the anti-itch blower can heat the skin to an effective temperature. The label/precautions may also tell the patient that they must continue to heat the skin for a period of time, such as 1-7 seconds, when they are already feeling tingling, tingling, mild pain, burning, and mild burning.
一个更先进的止痒吹风机，它包含一个激光距离传感器来显示距离，一个红外远程温度传感器来显示皮肤温度和一个机器人恒温器。在用户选定一种设置后，例如用于成人的腿部，机器人恒温器会根据距离设置热空气温度和空气流速，从而快速将皮肤加热到所需的温度，一旦皮肤达到所需的温度，机器人恒温器可以通过降低加热元件的供电来，或者通过减慢风扇的速度来减慢热空气的吹速，或者通过间歇性地关闭和打开止痒吹风机，使皮肤保持在所需的温度。空气的温度或空气的流速可以是恒定的。它也可以不断变化，比如上下起伏，所以要让皮肤温度保持在对皮肤瘙痒的有效温度。A more advanced anti-itch hair dryer that incorporates a laser distance sensor to display distance, an infrared remote temperature sensor to display skin temperature and a robotic thermostat. After the user selects a setting, such as for an adult’s legs, the robotic thermostat sets the hot air temperature and air flow rate based on distance, thereby quickly heating the skin to the desired temperature. Once the skin reaches the desired temperature, the robotic thermostat can either reduce the power to the heating element, slow down the speed of the fan, or keep the skin at the desired temperature by turning the anti-itch hair dryer off and on intermittently. The temperature of the air or the flow rate of the air may be constant. It can also be constantly changing, like going up and down, so keep the skin temperature at an effective temperature for itchy skin.
我们还可能会开发和使用一种软件，它可以告诉我们，一剂热量已经传递到皮肤上来消除瘙痒，并可以告诉恒温器在瘙痒消除时关闭止痒吹风机。We might also develop and use software that can tell us that a dose of heat has been delivered to the skin to relieve the itch, and that can tell the thermostat to turn off the anti-itch hair dryer when the itch is gone.
为了让远程距离测量器与恒温器一起工作，我们可以参考我们家庭加热系统所采用的方法。当测量器告诉恒温器距离很远时，恒温器将切换一根电线，通过一个较小欧姆的电阻，因此加热元件和/或风扇可以获得更大的功率。这样，更高的温度和更高的吹风速度的热空气就会吹到皮肤上。反之亦然。To get a remote distance meter to work with a thermostat, we can refer to the approach we take with our home heating system. When the gauge tells the thermostat to be far away, the thermostat will switch a wire through a smaller ohm resistor so more power can be drawn to the heating element and/or fan. In this way, hot air with a higher temperature and higher blowing speed is blown onto the skin. vice versa.
装置出风口与皮肤之间的起作用的距离是可变的。它取决于出风口的热空气的温度和气流速度。有一个普通的吹风机，温度在150℉左右，距离可以在1英寸左右。然而，只要止痒吹风机能将皮肤表面加热到特定情况下所需的温度附近，任何从1/4英寸到2英尺的其他距离都可以。恒温器可以从距离测量器获取距离。当我们想要确定对于一个特定的情况什么距离是合适的，我们需要调节设备出风口的热空气温度和气流速度。我们可以简单地使用我们从市场购买的吹风机的热空气温度和气流速度。然后我们用一个单独的温度传感器在离出风口约1/2到3英寸的距离测量热空气的温度。为了将皮肤加热到所需温度，热空气温度必须高于此温度2度或更多。The effective distance between the air outlet of the device and the skin is variable. It depends on the temperature and airflow velocity of the hot air at the outlet. With a normal hair dryer at around 150℉, the distance can be around 1 inch. However, any other distance from 1/4 inch to 2 feet will do, as long as the anti-itch blow dryer heats the surface of the skin to near the temperature required for the particular situation. The thermostat can get the distance from the distance measurer. When we want to determine what distance is appropriate for a particular situation, we need to adjust the hot air temperature and airflow velocity at the outlet of the equipment. We can simply use the hot air temperature and airflow speed of the hair dryer we bought from the market. We then measure the temperature of the hot air with a separate temperature sensor at a distance of about 1/2 to 3 inches from the outlet. In order to heat the skin to the desired temperature, the hot air temperature must be 2 degrees or more above this temperature.
因此如果在该距离时的温度在51℃左右，我们知道这个距离是合适的，可以将儿童皮肤瘙痒的皮肤加热到49℃左右，我们可以设计恒温器来设置热空气温度和/或空气流速至相应强度，并将其标记为儿童皮肤瘙痒使用的距离。如果它在52℃左右，我们知道对于成人皮肤瘙痒则对应将皮肤加热到50℃，和上面的一样做，等等。我们可以在用户的手册中推荐这些距离，或者在可调节的棍子的这些距离上作标记。如果我们使用一个远程距离测量器，我们可以使用LD屏幕向用户显示他们根据建议的情况正在使用一个距离。So if the temperature at that distance is around 51°C, we know this distance is appropriate to heat the child's itchy skin to around 49°C, we can design the thermostat to set the hot air temperature and/or air flow rate to the corresponding intensity, and mark it as the distance to use for the child's itchy skin. If it's around 52°C, we know that for adult skin itching corresponds to heating the skin to 50°C, doing the same as above, etc. We can recommend these distances in the user's manual, or mark these distances on the adjustable stick. If we use a remote distance measurer, we can use the LD screen to show the user that they are using a distance based on the suggested situation.
我们可以设计一个有温度传感器和距离测量器的止痒吹风机。我们可以设计一个止痒吹风机，当用户放置在远处的距离时，提供更高的热空气温度和/或更高的空气气流速度，反之亦然。然后让温度传感器测量皮肤温度，并指示恒温器打开或关闭加热元件和/或空气风扇。We can design an anti-itch hair dryer with temperature sensor and distance measurer. We can design an anti-itch hair dryer that provides higher hot air temperature and/or higher air velocity when placed at a greater distance by the user, and vice versa. Then let the temperature sensor measure the skin temperature and instruct the thermostat to turn the heating element and/or air fan on or off.
为了确保止痒吹风机总是对瘙痒有效，我们可以添加一个自动开关，当温度传感器检测到距离皮肤太远时，关闭风扇和/或加热元件的电源，并且只有当距离在有效范围内时才自动打开它们。To ensure that the anti-itch hair dryer is always effective for the itching, we could add an automatic switch that turns off the power to the fan and/or heating element when the temperature sensor detects that it is too far away from the skin, and automatically turns them on only when the distance is within effective range.
为了确保止痒吹风机的安全，自动开关还可以在距离皮肤太近时自动关闭设备，例如只有1/4英寸，以避免对皮肤造成伤害。当皮肤温度达到特定治疗所需的温度或不安全的温度(如成人的腿部，62℃)时，它也会关闭止痒吹风机。To ensure the safety of the anti-itch hair dryer, the automatic switch can also automatically turn off the device when it is too close to the skin, such as only 1/4 inch, to avoid damage to the skin. It also turns off the anti-itch hair dryer when the skin temperature reaches a temperature required for a specific treatment or an unsafe temperature (such as an adult's leg, 62°C).
自动开关将在设备到达距离皮肤的所需距离后，在短时间(如一秒钟)或皮肤冷却后重新打开电源。The automatic switch will turn power back on after the device has reached the desired distance from the skin, after a short period of time (such as one second) or after the skin has cooled.
加热可以被定量，当皮肤达到特定情况(如成人的腿部)下的作用温度，并在那里停留一段特定时间，如成人的腿部约7秒，设备可以关闭加热一段时间，如1-3秒，然后重新启动。The heating can be dosed, when the skin reaches the action temperature for a specific situation (such as an adult's leg) and stays there for a specific period of time, such as about 7 seconds for an adult's leg, the device can turn off the heating for a certain period of time, such as 1-3 seconds, and then restart.
方法实施例应包括以下步骤：打开可吹热空气的设备，将热空气对准有瘙痒的皮肤区域，移动设备直至设备与皮肤的距离在对皮肤瘙痒有效的距离内，并允许热空气吹到皮肤以消除皮肤瘙痒，当你感到灼热有几秒钟时取出设备。Embodiments of the method should include the following steps: turn on the device capable of blowing hot air, direct the hot air at the itchy skin area, move the device until the distance between the device and the skin is within an effective distance for itchy skin, and allow the hot air to blow on the skin to relieve itching, and take out the device when you feel burning for a few seconds.
设备的位置必须与皮肤保持在对皮肤瘙痒有效的距离。出风口的热空气温度和热空气吹风流速会确定这个距离。例如，如果我们设计一个类似于Conair Y260SR型、型号259Y、125V交流电、60Hz、1875W吹风机的止痒吹风机，我们可以进一步限制不同设置下的温度范围。当一个止痒吹风机被设计为在出风口处吹大约120℉的热空气，并且在空气流速类似于上述Conair吹风机设置得高时，用户应该将止痒吹风机的出风口置于离皮肤表面约1/2英寸处。当止痒吹风机被设计为在出风口处吹150℉左右的热空气时，用户应该将设备的出风口放置在离皮肤表面约1英寸处。当止痒吹风机设计用于吹180℉左右的热空气时，用户应该将设备的出风口放置离皮肤表面1-2英寸处。当止痒吹风机设计用于吹约200℉的热空气时，用户应将设备放置在离皮肤表面约2-3英寸处。如前所述，我们可以将所有这些信息放在用户手册或止痒吹风机的表面上。The device must be positioned at an effective distance from the skin for itching. The hot air temperature at the air outlet and the blowing velocity of the hot air will determine this distance. For example, if we design an anti-itch hair dryer similar to the Conair Model Y260SR, Model 259Y, 125VAC, 60Hz, 1875W Hair Dryer, we can further limit the temperature range at different settings. When an anti-itch hair dryer is designed to blow hot air at about 120°F at the outlet, and with the air flow rate set high like the above Conair hair dryer, the user should position the outlet of the anti-itch dryer about 1/2 inch from the skin surface. When an anti-itch hair dryer is designed to blow hot air at around 150°F at the outlet, the user should position the device's outlet about 1 inch from the surface of the skin. When an anti-itch hair dryer is designed to blow hot air around 180°F, the user should position the air outlet of the device 1-2 inches from the surface of the skin. When an anti-itch hair dryer is designed to blow hot air at about 200°F, the user should position the device about 2-3 inches from the surface of the skin. As mentioned, we could put all of this information on the face of an owner's manual or an itch-relieving hair dryer.
这种方法也应该有一个步骤，让热空气持续吹到皮肤区域，直到使用者感到刺痛，麻刺感，灼热，轻微灼烧或轻微疼痛的感觉持续几秒钟。This method should also have a step where hot air is continuously blown onto the skin area until the user feels a tingling, tingling, burning, slight burning or mild pain sensation for a few seconds.
