医院是各种病原体高度集中的场所, 医院感染不仅威胁着病人, 同时也严重 威胁着医护人员的健康和生命。现代基础医学研究证实,病毒的传播媒介可以是病 人的血液、 体液、 分泌物和排泄物。 1987年美国开始实施一种新的隔离方法一 -体 内物质隔离法, 即把病人体内物质都视为具有传染性, 同年美国医院联合咨询委员 会发表了《工作人员对血液传染疾病的保护声明》告诫医护人员应视所有病人的血 液、 体液都有危险性。 目前, 欧美发达国家在医院管理中已普遍实行体内物质隔离 法,在实施这种隔离法所釆用的隔离措施中, 口罩与护目镜被并列为在有可能被体 内物质溅入时须同时釆用的隔离措施。我国近几年出版的有关医院感染的著作中也 明确提出: 在防止病人的血液、 体液造成的感染时, 须用口罩和护目镜预防。事实 上, 医护人员在从事门诊、 紧急救护、 实施手术、 病人护理、 病理解剖、 科研实验 等常规工作时, 如果仅佩戴口罩, 病人的血液、 体液、 口腔分泌液飞沬可能直接溅 入医护人员的眼睛里, 造成对医护人员的感染, 包括爱滋病病毒的感染。 因此眼睛 的防护与口鼻的防护同样重要,但由于目前是采用佩戴护目镜来护目的,它是非一 次性的, 预防感染的效果受到影响, 同时, 佩戴的舒适性、 方便性也不理想。  Hospitals are places where various pathogens are highly concentrated. Nosocomial infections not only threaten patients, but also seriously threaten the health and lives of medical staff. Modern basic medical research confirms that the virus can be transmitted through the patient's blood, body fluids, secretions and excreta. In 1987, the United States began to implement a new isolation method-the body substance isolation method, which treats the patients' body substances as infectious. Medical personnel should treat all patients' blood and body fluids as dangerous. At present, the developed countries in Europe and the United States have generally implemented the body material isolation method in hospital management. In the isolation measures used in the implementation of this isolation method, masks and goggles are listed as being required to be simultaneously splashed by body material. Used isolation measures. In the literature on nosocomial infections published in China in recent years, it is also clearly stated that: To prevent infections caused by patients' blood and body fluids, masks and goggles must be used to prevent them. In fact, when medical personnel are engaged in routine work such as clinics, emergency rescue, performing surgery, patient care, pathological anatomy, scientific research experiments, etc., if only wearing a mask, the patient's blood, body fluids, or oral secretions may fly directly into the medical personnel. In the eyes, causing infections to health care workers, including HIV infection. Therefore, eye protection is as important as mouth and nose protection. However, since goggles are used for protection purposes, it is non-recurring, and the effect of preventing infection is affected. At the same time, wearing comfort and convenience are not ideal.
由于上述原因, 本人曾设计了一种能对使用者的眼睛起防护作用的防溅护目 口罩 (ZL99256581. 2 ), 但这种防溅护目口罩只适用于眼睛具有正常视力或佩戴隐 型眼睛的人员, 因为护目胶片是沿口罩片的上部向上延伸而成的, 因此护目胶片离 开佩戴者的眼睛的间距较小,护目胶片与佩戴者的眼睛架之间发生干涉并有可能影 响佩戴者的视线。 发明内容  Due to the above reasons, I have designed a splash-proof eye mask (ZL99256581. 2) that can protect the eyes of the user, but this splash-proof eye mask is only suitable for eyes with normal vision or wearing concealed For the eyes, because the eye protection film is extended upward along the upper part of the mask sheet, the distance between the eye protection film and the wearer's eye is small, and the eye protection film and the wearer's eye frame may interfere and may Affects the wearer's vision. Summary of the Invention

The mask includes a piece of masking film 10 that can be bent along the contour of a person's face. The masking film 10 is made of a sheet-shaped transparent material having a thickness of 0.06 to 0.25 mm. It is processed into a shape with a width of 20 to 40 cm and a height of 10 to 25 cm. The upper part of the protective film 10 is connected with the ribs 30 formed by a sheet-like elastic body having a certain strength between the upper part of the protective film 10 and the method of connecting the protective film 10 with the protective bands 20 and the ribs 30 by using ultrasonic waves. Welding, heat welding or riveting. The three pieces of the cover film 10, the band 20 and the ribs 30 can be in a flat and overlapping state with each other, as shown in Figs. When the cover film 10 and the shroud 20 are curved in an arc shape, the ribs 30 are supported between the cover film 10 and the shroud 20 which are radially separated from each other, as shown in FIG. 3, 4 shown. The tail ends of the shroud 20 may be in two states of being separated from each other and connected to each other, as shown in FIGS. 1 and 2 and FIGS. 3 and 4 respectively. The ribs 30 require an elastic material with a certain strength, which can ensure that it is not only conducive to being flatly overlapped with the protective film 10 and the band 20, but also can ensure that the ribs 30 can play a role in connecting the band 20 and the protective film 10 when worn. The role of disengagement from each other.
如图 1、 4, 护面胶片 10的上边设有一边沿围带 40, 筋条 30的两端分别与围 带 20和边沿围带 40连接。  As shown in FIGS. 1 and 4, a rim band 40 is provided on the upper side of the protective film 10, and both ends of the rib 30 are connected to the rim band 20 and the rim band 40, respectively.
如图 5、 6所示, 围带 20可包括两段长度大致相同的主段 21, 该段为具有一 定强度的弹性体, 其中间为一小段具有一定强度的柔性带体 22, 其长度根据佩戴 时因护面胶片 10和围带 20之间的间距而产生的弧长差值来定。 主段 21的尾端连 有便于系接的软质布带 23, 这是围带 20在佩戴时的一种连接方式, 它具有佩戴舒 适、便捷的优点。用于围带 20的另外一种连接方式是围带 20的尾端设有彼此配合 扣接的切口, 这种方式较为便捷, 如图 1、 2、 3、 4所示。 或者, 可以在围带 20 的两个尾端设置尼龙搭扣,这种连接方式更加便捷,而且便于根据使用者的头围大 小作出调节。 还有, 围带 20也可以连成一体, 其至少一部分是用弹性织带制成, 因而可以借助弹性直接将围带 20套在头上。  As shown in FIGS. 5 and 6, the band 20 may include two main sections 21 of approximately the same length. This section is an elastic body having a certain strength, and the middle is a small section of a flexible belt body 22 having a certain strength. The difference in arc length due to the distance between the protective film 10 and the band 20 during wearing is determined. A soft cloth band 23 is connected to the tail end of the main section 21, which is a connection method of the band 20 when it is worn. It has the advantages of being comfortable and convenient to wear. Another connection method for the shroud 20 is that the tail ends of the shroud 20 are provided with cutouts that cooperate with each other, which is more convenient, as shown in Figs. 1, 2, 3, and 4. Alternatively, Velcro can be provided at the two tail ends of the girth 20, which is more convenient and convenient for adjustment according to the size of the user's head circumference. In addition, the shroud 20 may also be integrated into one body, and at least a part of the shroud 20 is made of an elastic webbing, so that the shroud 20 can be directly put on the head by elasticity.
在图 4、 5中, 围带 20的带面上开有长方形口 24, 围带 20的带面上, 以其中 部为基准往两边呈相反方向开制若干个三边贯通的 U形切口,从而产生若干个根部 与带面相连的自然连体, 即能以其根部为轴在一定范围内旋转的舌状的矩形筋条 30。该筋条 30的另一端部与护面胶片 10连接, 筋条 3 0与护面胶片 10和围带 2 0 的连接部位构成两条被此平行的转轴, 这两个转轴与围带 20的长度方向垂直。 筋 条 30的运动方式仅限于以与围带 20的带面连体的根部为轴相对于带面旋转,并同 时受到与其端部相连接的护面胶片 10的弯曲度的制约, 当其旋转角度为零时, 护 面胶片 10、 围带 20及筋条 3 0三者处于平展叠合状态, 筋条 30恰好完全嵌入围 带 20上的长方形口 24内。 由于围带 20上有长方形口 24, 在佩戴时筋条 30向外 辐射状撑开,露出的长方形口 24可以确保使用者在长时间佩戴时额头处通风透气, 使佩戴者感觉舒适。围带 20的长度,扣接处的调节量或软质布带 23的系接部分的 余量应根据不同使用者的具体尺寸按系列制造。 另外, 在围带 20的侧面上可以覆 盖有例如海绵、 泡沫塑料之类的柔软材料, 以使佩戴者感觉更加舒服。  In Figs. 4 and 5, a rectangular opening 24 is opened on the band surface of the band 20, and a plurality of three-sided U-shaped cutouts are formed on the band surface of the band 20 in opposite directions to the two sides with reference to the middle portion. As a result, a number of natural conjoined bodies whose roots are connected to the belt surface, that is, tongue-shaped rectangular ribs 30 that can rotate within a certain range with the roots as the axis. The other end of the rib 30 is connected to the cover film 10, and the connection portion between the rib 30 and the cover film 10 and the shroud 20 forms two parallel rotating shafts, and these two shafts are connected to the shroud 20 The length is vertical. The movement of the ribs 30 is limited to the rotation with respect to the belt surface taking the root connected with the belt surface of the belt 20 as an axis, and at the same time, it is restricted by the curvature of the cover film 10 connected to its end portion. When the angle is zero, the protective film 10, the band 20, and the ribs 30 are in a flat overlapping state, and the ribs 30 are exactly embedded in the rectangular opening 24 on the band 20. Because the band 20 has a rectangular opening 24, the ribs 30 are radiated outwards when worn, and the exposed rectangular opening 24 can ensure that the user is ventilated and foreheaded when wearing for a long time, making the wearer feel comfortable. The length of the shroud 20, the adjustment amount at the buckle, or the balance of the tethered portion of the soft cloth tape 23 should be manufactured in series according to the specific dimensions of different users. In addition, the side of the shroud 20 may be covered with a soft material such as sponge or foam plastic to make the wearer feel more comfortable.
所述的与长方形口 24可对应叠合的筋条 3 0的宽度小于并接近该长方形口 24 的宽度, 筋条 3 0与护面胶片 10的结合部位可处在上述长方形口 24的范围内。此 处所述的长方形口 24与筋条 30的大小及连接位置实际上属于加工工艺结枸,即当 围带 20与护面胶片 10选用可彼此焊接的材料时, 上述结构便于焊接。 The width of the rib 30 corresponding to the rectangular opening 24 may be smaller than and close to the width of the rectangular opening 24, and the joint portion of the rib 30 and the cover film 10 may be within the range of the rectangular opening 24 described above. . The size and connection position of the rectangular opening 24 and the ribs 30 described here actually belong to the processing technology, that is, when The above-mentioned structure is convenient for welding when the band 20 and the cover film 10 are made of materials that can be welded to each other.
当护面胶片 10的材质及厚度适当时, 也可以直接在护面胶片 10的上部沿边 开制出若干相向的 U形切口, 产生同前述的在围带 20上开制出 U形切口类似的情 况, 此处不再赘述。 应注意的是, 若在护面胶片 10切出 U形切口, 同时由于在围 带 20上也有长方形口 24, 这样可能会出现局部额头暴露的情况, 此时可以考虑在 护面胶片 10的 U形切口处加设一条护条之类的辅条, 从而确保防溅屏障完整。  When the material and thickness of the protective film 10 is appropriate, a plurality of opposite U-shaped cuts can also be made directly on the upper edge of the protective film 10, which is similar to the aforementioned U-shaped cuts made on the band 20. The situation is not repeated here. It should be noted that if a U-shaped cut is made in the protective film 10, and there is also a rectangular opening 24 in the band 20, this may cause partial forehead exposure. At this time, the U in the protective film 10 may be considered. An auxiliary strip, such as a guard strip, is added at the cutout to ensure that the splash barrier is complete.
不论是在护面胶片 10还是在围带 20上切制 U形切口构成筋条 30,在筋条 30 与其母体之间保留的自然连体的根部应留出消除应力集中的切痕,此处可用圆弧过 渡的根部切痕, 以保证筋条 30与其母体之间连接的强度。  Regardless of whether U-shaped cuts are made on the protective film 10 or on the girth 20 to form the ribs 30, the root of the natural conjoined body retained between the ribs 30 and its parent should leave a cut to eliminate stress concentration, here An arc cut can be used to ensure the strength of the connection between the rib 30 and its parent.
另外, 若适当控制护面胶片 10的周边轮廓和尺寸, 本实用新型完全可以制成 一个护目胶片的护目装置, 此结构仍属于本实用新型的保护范围。  In addition, if the peripheral contour and size of the protective film 10 are properly controlled, the utility model can be made into an eye protection device of the protective film. This structure still belongs to the protection scope of the utility model.
