技术领域technical field

本发明涉及一种热疗用巩膜敷贴装置。The invention relates to a sclera sticking device for thermotherapy.

背景技术Background technique

视网膜母细胞瘤(retinoblastoma，Rb)是婴幼儿最常见的一种原发性眼内恶性肿瘤，严重地威胁着患儿的视力、眼球，以及生命安全。视网膜母细胞瘤治疗方法很多，大体可分为保留眼球治疗和眼球摘除两大类。为了提高视网膜母细胞瘤患儿生活质量，并随着视网膜母细胞瘤诊疗技术水平的提高，视网膜母细胞瘤的保留眼球治疗方法越来越受到眼科医生的重视。我国视网膜母细胞瘤患儿就诊时多为晚期，目前现有的治疗方法对晚期肿瘤治疗效果较差，眼球保存率低。为了提高视网膜母细胞瘤治疗效果，有必要寻找更有效更经济的治疗方法。Retinoblastoma (Rb) is the most common primary intraocular malignant tumor in infants and young children, which seriously threatens the vision, eyeball and life safety of children. There are many treatment methods for retinoblastoma, which can be roughly divided into two categories: eyeball preservation treatment and eyeball enucleation. In order to improve the quality of life of children with retinoblastoma, and with the improvement of retinoblastoma diagnosis and treatment technology, the eyeball-sparing treatment of retinoblastoma has been paid more and more attention by ophthalmologists. Most of the children with retinoblastoma in my country are in the late stage when they go to the doctor. Currently, the existing treatment methods are poor in the treatment of advanced tumors, and the eyeball preservation rate is low. In order to improve the therapeutic effect of retinoblastoma, it is necessary to find more effective and economical treatment methods.

温热治疗是视网膜母细胞瘤许多重要的治疗方法中的一种。温热治疗是利用物理能量在组织中沉淀而产生热效应，使肿瘤组织温度上升到有效治疗温度，并维持一段时间，以杀死癌细胞，又不损伤正常细胞的一种治疗方法。温热治疗被认为是继手术、放疗、化疗和生物疗法后的又一种重要的肿瘤治疗方法。温热治疗不但对肿瘤细胞有直接的细胞毒效应，还可以增强化疗、放疗的疗效，提高机体的免疫力，抑制肿瘤的转移。因而被国际医药界称之为“绿色疗法”，日本专家称之为“医疗春天到来的标志”。Thermotherapy is one of many important treatments for retinoblastoma. Hyperthermia therapy is a treatment method that uses physical energy to precipitate in the tissue to produce a thermal effect, raise the temperature of the tumor tissue to an effective therapeutic temperature, and maintain it for a period of time to kill cancer cells without damaging normal cells. Thermotherapy is considered to be another important tumor treatment method after surgery, radiotherapy, chemotherapy and biological therapy. Thermotherapy not only has a direct cytotoxic effect on tumor cells, but also can enhance the curative effect of chemotherapy and radiotherapy, improve the body's immunity, and inhibit tumor metastasis. Therefore, it is called "green therapy" by the international medical community, and Japanese experts call it "the sign of the arrival of medical spring".

加热治疗肿瘤的机制，目前有多种观点。Song认为存在两种机制：当温度足够高时(＞43℃)，肿瘤血管闭塞，热直接杀伤肿瘤细胞；低于43℃时，增加肿瘤血流量，促进再氧合，增强放疗效果。43℃是细胞膜相变温度，哺乳动物细胞在高温作用下对糖酵解能量代谢依赖性增加，基本上靠无氧代谢得以生存。缺氧产生的一系列细胞因子破坏肿瘤内的血管内皮造成血栓栓塞以致肿瘤缺氧坏死。另外，热疗后酸性代谢产物乳酸和β羟丁酸含量明显增加，更加剧肿瘤细胞死亡，热疗主要作用在肿瘤细胞的细胞膜和细胞核。There are currently many views on the mechanism of heating to treat tumors. Song believes that there are two mechanisms: when the temperature is high enough (>43°C), tumor blood vessels are occluded, and the heat directly kills tumor cells; when the temperature is lower than 43°C, tumor blood flow is increased, reoxygenation is promoted, and the effect of radiotherapy is enhanced. 43°C is the phase transition temperature of the cell membrane. Mammalian cells rely more on glycolysis energy metabolism under the action of high temperature, and basically rely on anaerobic metabolism to survive. A series of cytokines produced by hypoxia destroy the vascular endothelium in the tumor and cause thromboembolism, resulting in tumor hypoxia necrosis. In addition, the content of acidic metabolites lactic acid and β-hydroxybutyric acid increased significantly after hyperthermia, which aggravated the death of tumor cells. Hyperthermia mainly acts on the cell membrane and nucleus of tumor cells.

大致来说，加热方法有两大类：侵入性加热和非侵入性加热。侵入性加热优点是定位准确，加热控制易实现。加热方式包括微波，远红外线，超声等。目前对于眼部肿瘤的温热治疗研究较少，多处于初期研究模拟试验或动物试验阶段，也没有有效的侵入性加热的仪器。Broadly speaking, there are two broad categories of heating methods: invasive heating and non-invasive heating. The advantages of invasive heating are accurate positioning and easy heating control. Heating methods include microwave, far infrared, ultrasonic and so on. At present, there are few studies on thermotherapy for ocular tumors, and most of them are in the stage of initial research simulation experiments or animal experiments, and there is no effective invasive heating equipment.

目前应用于其他领域的电热元件的种类和特征如下所述：The types and characteristics of heating elements currently used in other fields are as follows:

电热元件的种类与特点：电热元件是实现电能向热能转化的一类元件，各种的电热设备都要使用电热元件来发热。电热元件从问世的那一天起，就在人们的生产生活中担任着重要的角色。电热元件的种类如下所述。Types and characteristics of electric heating elements: electric heating elements are a type of element that realizes the conversion of electric energy into heat energy, and all kinds of electric heating equipment must use electric heating elements to generate heat. Electric heating elements have played an important role in people's production and life since the day they came out. The types of heating elements are as follows.

1、电热丝1. Heating wire

电热丝是最早出现的一种电热元件，它是以电热为基本工作原理来实现能量转化的。电热丝虽然为传统电热元件，但至今尚未被替代，现在电热丝依然在各个领域，特别是工业生产及实验室被广泛使用。Heating wire is the earliest electric heating element, which uses electric heating as the basic working principle to realize energy conversion. Although the heating wire is a traditional heating element, it has not been replaced so far. Now the heating wire is still widely used in various fields, especially in industrial production and laboratories.

电热丝在近年来多采用铁铬铝合金和镍铬合金，铁铬铝合金的最高温度已经达到了1400℃。也可以利用碳纤维电热。电热丝的基础上，近些年发展出了电热棒、电热盘、电热片等电热元件，但它们的本质依然是电热丝，其原理也脱离不了电热。In recent years, iron-chromium-aluminum alloys and nickel-chromium alloys have been mostly used in heating wires, and the maximum temperature of iron-chromium-aluminum alloys has reached 1400°C. Carbon fiber electric heating can also be used. On the basis of heating wires, electric heating elements such as electric heating rods, electric heating plates, and electric heating sheets have been developed in recent years, but their essence is still electric heating wires, and their principles cannot be separated from electric heating.

电热丝的优点是加热温度和耐热温度高，技术成熟、易于制造且方便配套应用于各种电热设备。电热丝的缺点是它的能量转换率较低，发热过程中伴随着发光过程，因此电能转换率只能达到60％到70％。The advantages of heating wire are high heating temperature and heat resistance temperature, mature technology, easy manufacture and convenient matching for various electric heating equipment. The disadvantage of the heating wire is that its energy conversion rate is low, and the heating process is accompanied by a luminous process, so the electric energy conversion rate can only reach 60% to 70%.

2、PTC电热元件2. PTC heating element

PTC的全称是Positive Temperature Coefficient，也就是热敏电阻，它是将导电材料经过复合烧结而成的一种电热元件。PTC电热元件是继电热丝之后出现的一种电热元件，受限于居里温度的限制，只能在350℃以下的加热中使用，应用于各种小功率低温电热设备。The full name of PTC is Positive Temperature Coefficient, that is, thermistor, which is an electric heating element made of conductive materials through composite sintering. PTC heating element is a kind of heating element that appeared after the heating wire. It is limited by the Curie temperature and can only be used in heating below 350 ° C. It is used in various low-power low-temperature electric heating equipment.

PTC电热元件的优点是加热时无明火，加热效率可达70％。PTC电热元件的缺点是抗震性能差、不能随意切割使用，特别是PTC电热元件受居里温度的限制，不能用于350℃以上的加热，因此PTC电热元件在实际生产生活中的应用只能局限在低温加热领域。The advantage of PTC electric heating element is that there is no open flame when heating, and the heating efficiency can reach 70%. The disadvantage of PTC heating elements is that they have poor shock resistance and cannot be cut and used at will. In particular, PTC heating elements are limited by the Curie temperature and cannot be used for heating above 350°C. Therefore, the application of PTC heating elements in actual production and life can only be limited. In the field of low temperature heating.

3、导电涂料3. Conductive coating

导电涂料也被称为黑膜，产生于20世纪50年代末，在被喷涂于绝缘材料表面后可以作为电热元件使用。导电涂料本身的用途很多，而作为电热元件的应用较少，它的优点是面状加热、散热面积大、抗震性能好，但缺点是发热层易脱落，且只能适用于200℃以下加热。Conductive paint, also known as black film, was produced in the late 1950s and can be used as an electric heating element after being sprayed on the surface of insulating materials. Conductive paint itself has many uses, but it is rarely used as an electric heating element. Its advantages are planar heating, large heat dissipation area, and good shock resistance, but its disadvantage is that the heating layer is easy to fall off, and it can only be used for heating below 200 °C.

4、电热膜4. Electric heating film

电热膜是近年来新兴的一种电热元件，它是吸取了PTC和导电涂料两种电热元件的特点制造而成的。电热膜目前主要应用在室内取暖和环境温度保持等方面，如建筑物取暖、育雏室保温等。Electric heating film is a new electric heating element in recent years. It is manufactured by absorbing the characteristics of two electric heating elements, PTC and conductive paint. Electric heating film is currently mainly used in indoor heating and environmental temperature maintenance, such as building heating, brooding room insulation, etc.

电热膜的优点是无明火加热、面状加热、热阻少、导热快、使用寿命长，且易于切割和分离，特别是电热膜的电能转换效率高达90％、热能损失小。The advantages of the electrothermal film are no open flame heating, planar heating, less thermal resistance, fast heat conduction, long service life, and easy cutting and separation, especially the electric energy conversion efficiency of the electrothermal film is as high as 90%, and the heat loss is small.

电热膜的缺点是升温速度慢、加热温度尚不能达到较高数值，停电后热量消散速度快。The disadvantage of the electric heating film is that the heating speed is slow, the heating temperature cannot reach a high value, and the heat dissipation speed is fast after a power failure.

电热膜为半透明的膜状聚酯，是一种新兴的电热设备。电热膜本身即为发热体，在通电以后可以将热量以辐射的形式散入周围空间，能实现良好的均匀散热效果。电热膜目前主要应用在室内采暖方面，其效果优于传统的供暖方式。The electric heating film is a translucent film-like polyester, which is a new electric heating device. The electrothermal film itself is a heating element, which can radiate heat into the surrounding space in the form of radiation after electrification, and can achieve a good uniform heat dissipation effect. Electrothermal film is currently mainly used in indoor heating, and its effect is better than traditional heating methods.

1、电热膜的结构1. The structure of the electrothermal film

电热膜是由电热膜片、连接部件和温控器组成的，其中电热膜片是电热膜系统中的发热部件，电热膜片的基材是PET特制聚酯膜，发热材质为墨线，导电材质为金属载流条。电热膜的连接部件有连接导线、连接卡和绝缘罩，用以连接电热膜的电路，及控制电热膜运行安全。The electric heating film is composed of electric heating diaphragm, connecting parts and temperature controller. The electric heating diaphragm is the heating part in the electric heating film system. The base material of the electric heating diaphragm is PET special polyester film. The heating material is ink line and conductive material For the metal current-carrying bar. The connecting parts of the electric heating film include connecting wires, connecting cards and insulating covers, which are used to connect the electric heating film circuit and control the safe operation of the electric heating film.

2、电热膜片的原理2. The principle of electrothermal diaphragm

电热膜的墨线被平行、均匀的铺设在聚酯薄膜内，两端由相当于电线的金属载流条相连，形成多根并联电阻。电热膜通电后，在金属载流条的接通下，墨线通电发热。The ink lines of the electrothermal film are laid parallel and evenly in the polyester film, and the two ends are connected by metal current-carrying bars equivalent to electric wires to form multiple parallel resistors. After the electrothermal film is energized, the ink line is energized and heats up under the connection of the metal current-carrying bar.
