Description

膜热恒温式间接喉镜
                      技术领域
本实用新型涉及间接喉镜的改进，具体地说是一种膜热恒温式间接喉镜，适用于咽喉病变的窥视检查。
                      背景技术
间接喉镜是耳鼻喉科医生用于咽喉部常规检查的常用器具，由镜片、镜片固定壳、手柄构成，手柄为直径3-5mm、长200mm的钢丝，与镜片固定壳固定为一整体，并呈一定角度，对于下咽部肿物、喉及下咽部病变必须借助间接喉镜才能窥视检查，使用时，首先将镜片及镜片固定壳置于酒精灯上加热，使镜片温度升至38-40℃C，再放入口中，通过反射进行检查，加热至38-40℃C的目的是防止镜面结雾，但这种间接喉镜的缺点是：放入口腔后，因温度往往不易控制，温度偏低时呼吸气流的温度高于镜面温度，往往在镜片表面凝结一层雾滴，影响检查质量，温度过高时，又易造成烫伤。
                      发明内容
本实用新型的目的在于提供一种温度可自行加热，且温度可视，并自动控制在36-40℃之间的膜热恒温式间接喉镜。
为达到以上目的，本实用新型所采用的技术方案是：该膜热恒温式间接喉镜，由镜片、镜片固定壳、手柄构成，在镜片与镜片固定壳的底部之间夹有膜加热片，膜加热片周沿的外侧设有双金属温度感应片自控开关，膜加热片通过导线与电池连接，手柄为空心管，管内设有温度显示表。本实用新型还通过如下措施实施：所述的膜加热片为圆形的绝缘陶瓷薄片和电热膜层构成，电热膜层涂敷在绝缘陶瓷薄片朝镜片的一面上，电热膜层主要用聚脂、石墨等材料制作，电热膜层的一端通过导线连接电池，另一端接在内部触点上；所述的双金属温度感应片自控开关为一双金属片半圆环，受热涨开，温度降低收缩，其一端固定在绝缘陶瓷薄片上，另一端通过绝缘接头固定上开关触点，开关触点通过导线与电池连接；所述的温度显示表为酒精柱温度表，其感应头部设在镜片的底部，可及时显示镜片的温度；二根导线均设在手柄的空心管内，电池设在手柄端部管内，并设有开关。应用本实用新型时，先打开开关，接通电池，膜加热片开始发热，当温度显示表上的数值超过36℃时，即可使用，若超过40℃时，由双金属温度感应片的涨开力使电路自动断开，膜加热片不再加热，保证安全使用。
本实用新型的有益效果在于：与目前使用的间接喉镜相比，温度可显示，并可将镜片温度自动控制在安全范围内，使用可靠、不结雾、提高了检查质量。
                     附图说明
图1为本实用新型结构主视示意图。
图2为本实用新型沿轴线剖视示意图。
图3为本实用新型电热膜层及双金属感应片自控开关示意图。
图4为本实用新型温度显示表示意图。
                    具体实施方式
参照附图1、2、3、4制作本实用新型。该膜热恒温式间接喉镜，由镜片1、镜片固定壳2、手柄3构成，在镜片1与镜片固定壳2的底部之间夹有膜加热片4，膜加热片4周沿的外侧设有双金属温度感应片自控开关5，膜加热片4通过导线6与电池7连接，手柄3为空心管，管内设有温度显示表8。所述的膜加热片4为圆形的绝缘陶瓷薄片13和电热膜层12构成，电热膜层12涂敷在绝缘陶瓷薄片13朝向镜片1的一面上，电热膜层12主要用聚脂、石墨等材料制作，其制作方法为公知技术，故不再描述，电热膜层12的一端通过导线6连接电池7，另一端接在内部触点上；所述的双金属温度感应片自控开关5为一双金属片半圆环9，受热涨开，温度降低收缩，其一端固定在绝缘陶瓷薄片13上，另一端通过绝缘接头10固定上开关触点11，开关触点11通过导线6′与电池7连接；所述的温度显示表8为酒精柱温度表，其感应头部设在镜片1的底部；二根导线6、6′均设在手柄3的空心管内，电池7设在手柄3端部管内，并设有开关14。
