Description

可插拔的等离子体放电管装置 技术领域
本发明涉及一种可插拔的等离子体放电管装置，尤其是涉及一个壳体可手持的、等离子体放电管是由插拔方式与壳体连接的、单电极放电的、产生准辉光冷等离子体的装置。该装置所产生的等离子体主要是用于对敏感皮肤表面的消毒、灭菌、面部美容、治疗皮肤组织感染治疗以及癌细胞的杀灭。
背景技术
人们已经普遍证明低温冷等离子体可以快速杀灭各种病菌、病毒和癌细胞，同时也具有皮肤美容的作用。这是由于低温冷等离子体的内包含大量的电子、离子以及一些活性自由基等能量粒子，这些能量粒子作用到人体组织，可以杀灭各种病菌。
由于人体有限的耐受性，等离子体在作用于人体皮肤表面灭菌及杀灭病毒时，等离子体的宏观温度不能太高，不能形成电弧放电，否则会灼伤皮肤，人体难以接受。
因此在处理人体皮肤表面时，寻找一个放电强度可以很好的控制的、常压下小功率的、均匀放电的、准辉光的低温冷等离子体是十分必要的。
过去人们普遍采用的低温冷等离子体电容耦合放电方式是：在两个电极所构成的电容之间的放电，所产生的等离子体束流是从两个电极之间由气流携带喷出的。例如ZL200820180894.7公开了常压等离子体束照射装置，该专利是典型的介质阻挡电容耦合的放电结构，其管内是高压电极，地电极包覆在管外。其等离子体射流流出的方向是与两个电极之间 的电离电场方向垂直的。对于这种结构的放电情况，当人体皮肤接近喷口时很容易在内电极和人体之间形成电弧，为了避免电极对皮肤形成电弧，这种形式的放电要求人体皮肤离开喷口要有足够长的距离。此外，这种两个电极的电容耦合放电方式，其结构相对繁杂。
过去人们普遍采用的低温冷等离子体电感耦合放电方式是：等离子体发生器是螺旋管形式，螺旋管的两端分别与电源的两个输出端连接。例如：专利KR101260893公开了采用螺线管线圈电极的方式产生等离子体，这种方式高压电极是缠绕在等离子体发生管的外部，是属于电感耦合的放电形式，该放电螺旋管无法直接手持，且电极缠绕也有一定的制作难度。
CN 101848595A公开了采用射频电源的放电形式，这种射频等离子体，所要求的电极是金属电极，其外部要包覆对外屏蔽的地电极，等离子体放电也必须是采用惰性气体氦气才能形成电离放电。射频放电时，电极不能直接接触皮肤；此外，射频外露时，对外辐射大，也会干扰其它电器使用。
GB 2508176A所强调的等离子体发生头，是采用射频电源驱动的，形成的是射频尖端放电，直接电离空气。这种放电不能直接作用于对人体皮肤的处理，只是用于净化空气的目的。
目前我们看到的这些低温冷等离子体装置，其电极部位都没有采用插拔连接的方式的结构设计。等离子体用于对人体放电时，其外部与人体皮肤接触的部位，在用于不同的患者时必须更换，以免带来可能的交叉感染。
过去所见到等离子体射频电刀和高频电刀是用于切割皮肤组织，它是利用的等离子体放电电弧，这种电弧放电局部能量比较大，不能用于一般性的皮肤表面感染，杀灭表面的真菌，更不适合只是刺激激活皮肤组织来用于美容的目的。
采用介入式等离子体对体内组织处理时，需要把从等离子体喷口喷出的气体再抽出体外，需要设计抽气管道，目前尚未没有见到同心套管的吸气装置设计。
过去所见到的等离子体发生装置，其电源是采用一般的交流供电，通常的供电电压是220V或110V，这种是供电是直接把AC变成DC，再通过高频信号所驱动的开关管形成脉冲信号来驱动高压变压器形成高频高压的对外输出。采用这种方式的电源，即使电源中设有短路保护、过流、过压保护等措施，但当等离子体放电电极对人体皮肤进行放电时，人们在心里上的都有恐惧感。目 前还尚未见到等离子体电源的输入供电是通过连接低压直流电源适配器或是与电池连接的设计，更没有电源的输入接口采用USB口的连接形式，我们商未见到通过与计算机USB接口供电就能产生用于皮肤表面灭菌的等离子体装置。

具体实施方式
实施例一
参照附图1、2、3和5所给出的是本发明具体实施例一的详细描述。其特征在于：一个可手持的塑料壳体100内包含有一个等离子体电源107、塑料固定支架106、金属套筒103、连接导线104。在该壳体上设有功率调节开关105，电源输入端连接插头108等。该实施例的优点是该设备部件都集成在手持壳体内，体积小、重量轻、容易操作。
参照图1和图3所示，等离子体放电管是通过插拔方式与手持壳体100连接的，其插拔连接方法是等离子体放电管的金属电极杆101端穿过一个固定在壳体100上的橡胶材料定位套筒103A，插入到一个金属套筒103内与该金属套筒连接，该金属套筒103是由铜或不锈钢材料制成，它被固定在壳体100内的绝缘支架106上， 并与电源107的一个输出端连接，该绝缘管102的密闭端是暴露在手持壳体100的外部。这种等离子体放电管与壳体100的插拔连接方式的优点是定位准确，插拔连接方便，易于使用后更换。
参照附图3，等离子体放电管的制作方法是：在一个一端密闭的绝缘管102内插入一个金属电极杆101，该金属电极杆101可以采用铜、不锈钢或钨铜合金等。该金属电极杆101的一部分是外露在该绝缘管102外，金属电极杆101与绝缘管内壁之间的间隙是灌入导电粉101A，该导电粉可为铝粉、银粉、石墨粉等。在绝缘管102的端口处设有密封胶101B密封，该密封胶101B可以采用导电硅胶。这样制成的等离子体电极管，其管内不会有空气间隙，避免了管内部间隙放电。
参照图5，等离子体放电管的管外感应放电方式是指当人体皮肤与放电管102的接触间隙在2mm以内的范围时，或是人体皮肤在接触到放电管(绝缘管)102的外部表面时，接触间隙的空气被放电管102外表面的感应极化电荷击穿形成准辉光的冷等离子体放电。该放电管离开人体皮肤的距离超过2mm时，就不再产生等离子体放电。该等离子体放电是在空气中进行，无需要额外的工作气体，该等离子体的放电强度可以通过开关旋钮105来调节。
参照图6和图7，本发明实施例一中所要求的等离子体电源107的变压器输出端的电压范围是4～15kV，频率范围是1～500kHz，功率范围是0～30W。该电源的另一输出端是与其自身的地线连接，如图2所示。
等离子体电源107所要求的供电是12V内的低压直流供电，例如：连接一个电源适配器300，如图6所示；或是通过USB接口211与5V供电电池200连接，如图7所示。这种等离子体电源107的供电连接设计是为了保证等离子体放电管对人体产生等离子体放电时的安全性。
实施例二
图4是本发明实施例二的等离子体管外感应放电管的端部是弯曲头，这是实施例二和实施例一的唯一不同之处。这种密闭端部弯头形状的等离子体放电管与实施例一的直管形式比较，其所产生的等离子体可以在弯头的弧面上。这种结构的设计的优点是：等离子体放电管的端部放电时，易于从侧面观察。该实施例二的其它结构设计与实施例一是完全相同。
在本发明实施例一和二中，等离子体放电管的一端是插入在金属套筒103中，该金属套筒103通过导线104与等离子体电源107的输出端连接，其连接方式参见图1、2、3和4。实施例一和二中，在等离子体放电管的外围不设有其它电极。图2为单电极等离子体连接方式以及电源结构原理框图。
实施例三
参照图8，是有供气源的等离子体管内自持放电方式，该设备是采用一个两端开口的医用塑料管102A，该医用塑料管102A是通过插拔方式与手持壳体100上的连接头100A连接，该连接头100A设有一个圆形的气孔开口103B实现插拔连接，该圆形的气孔开口103B内设有弹性密封圈103C，该塑料管102A插入壳体的气孔开口103B后，与手持壳体100内的进气通道109A以及供气源109形成气路贯通。
参照图8，在手持壳体100的开孔内设有一个单金属电极101，该单金属电极101可以是铜杆、不锈钢杆或是钨铜杆，该金属电极101的端部是在壳体100内的气体通道中，该金属杆电极101的端部也可以采用介质管(比如陶瓷管或石英管)包覆，该电极杆101是 通过导线104与手持壳体100上的电极接头108连接，该电极连接头108再通过包覆有绝缘材料的导线104A与壳体100外的等离子体电源107的一个输出端连接，该电源107的另一个输出端是与其电源线路中的地线连接；该电源107输入端是与输出直流电压在12V以内的电源适配器300连接。
参照图8和9，当供气源109的惰性气体通过电极101的端部时，惰性气体被击穿形成等离子体自持射流放电111，该等离子体射流111流过可插拔的塑料管102A，并从其管口向外喷出。该等离子体射流的强度可以通过调节电源的输出功率和控制气体流量开关109B来控制。
参照图8，该塑料管102A的喷口与电极101端部要保持一定的距离，即为该塑料管102A的长度是要求大于60mm，该管的直径范围是：1-20mm，该尺寸限定是为了当人体皮肤接近塑料管喷射口时，避免电极101直接与人体形成电弧放电。
参照图8的有供气源的等离子体管内自持放电结构，实施例三中手持壳体100和电源107是通过电缆104A连接；手持壳体100和供气源是通过气管109A连接。
供气源109为惰性气体，可以采用氩气、氦气以及两者的混合气体。
本发明实施例三中所要求的等离子体电源107的输出端输出的电压范围是4～25kV，频率范围是1～500kHz，功率范围是0～100W。该电源的另一端是与其自身的地线连接，其连接方式如图2所示。
本发明实施例三中所要求的等离子体电源107的供电是12V内的低压直流供电，例如：连接一个电源适配器300，该适配器300的输出电压为12V。这种等离子体电源107与通常的220V/或110V通过低压直流隔离的方式，保证了等离子体放电管对人体表面放电时的安全性。
实施例四
图10给出的本发明实施例四有供气源放电的另一种端部形状等离子体管内自持放电的端部结构示意图。它和本发明实施例三的区别是等离子体放电管端部形状是采用弯头的塑料管102B，该形状放电，可方便用于对口腔皮肤感染的等离子体治疗。
实施例五
图11为本发明实施例五有供气源的带有吸气系统的等离子体管内自持放电结构剖视示意图。该塑料管102A的外部可再套有一个同心的外塑料管102C，外塑料管102C与内塑料管102A之间设有一定的间隙110B，该间隙110B的宽度在1mm内，外塑料管102C比内塑料管102A的长度长出一定的范围2～20mm，外塑料管102C也是通过插拔方式插入手持壳体100的连接头100A中，并通过手持壳体100中的吸气管110A与壳体100外的吸气泵110连接贯通，喷出等离子体内放电管(塑料管102A)管口的气体，由吸气泵110从外塑料管102C与内塑料管102A之间的间隙110B，以及手持壳体100内的吸气通道110A向外抽出。
图11中所述的本发明实施例五中的电极结构、连接方式、供气源和电源要求与实施例三完全相同。不同之处是在原来的塑料管102A外又套了一个同心外塑料管，多出抽气通道和一个抽气泵。该两个管在保持其一定间隙的情况下，也可以采用连体结构。所采用的塑料管都是采用医用的塑料材料。
图11中的本发明实施例五，带有吸气系统的目的是用于体内介入式等离子体治疗，是把流出放电管端部的等离子体气体，通过 吸气泵和吸气管抽出体外。
上面参考附图结合具体的实施例对发明进行了描述，然而，需要说明的是，对于本领域的技术人员而言，在不脱离本实用新型的精神和范围的情况下，可以对上述实施例作出许多改变和修改，这些改变和修改都落在本实用新型的权利要求限定的范围内。
