配送装置Distribution device

本发明涉及安全装置。概括地说，它涉及一种用于液体配剂的配送器，该装置可特别但并非唯一用作洗眼药水站。The present invention relates to safety devices. Broadly speaking, it relates to a dispenser for liquid dosing, the device being particularly, but not exclusively, useful as an eyewash station.

雇员和雇主自然地都关心工作场所的安全。此外，政府在众多行业实施严格的安全要求，如果违反这些安全要求就会处以罚款。Both employees and employers are naturally concerned about workplace safety. In addition, the government enforces stringent safety requirements across numerous industries, and fines are imposed if these safety requirements are violated.

人眼对与之接触后会刺激和可能永久损害眼睛的气体、液体和固体非常敏感。因此，对产生大量烟尘的行业，例如采矿业，其中一个安全要求就是提供适当的装置来确保员工可以从眼睛中冲洗掉这些刺激物。The human eye is very sensitive to gases, liquids and solids which upon contact can irritate and possibly permanently damage the eye. Therefore, one of the safety requirements for industries that generate large amounts of fumes, such as mining, is to provide adequate devices to ensure that workers can flush these irritants from their eyes.

一个减轻刺激的方法是在眼睛里施加医药液体配剂，即通常所称的洗眼药水。其中一个很受欢迎的配剂是含盐溶液。这种洗眼药水通常装在存放于急救站且需要时即可使用的瓶子里。One way to relieve irritation is to apply a medicinal liquid formulation, commonly known as an eyewash, to the eye. One of the most popular formulations is a saline solution. This eyewash is usually in a bottle that is kept at first aid stations and ready to use when needed.

尽管现在已经有很多种可利用的配送瓶，但这些现有技术装置的一个缺陷是它们很难被人使用，尤其是当使用者已经暂时失明并且无法得到帮助时。当工业界为了削减运行费用而逐渐不再雇佣专门的安全职员时，这种情况尤其需要特别考虑。取消安全职员带来的另外一个问题是安全设备不再经常被定期检查是否处于良好的可操作状态，当使用时这些设备也许会失效。Although there are a wide variety of dispensing bottles available, one drawback of these prior art devices is that they are difficult to use, especially when the user is temporarily blind and unable to obtain assistance. This is especially the case when industry is moving away from employing dedicated security staff in order to cut operating costs. Another problem posed by the elimination of safety personnel is that safety equipment is no longer routinely checked to be in good working order and may fail when in use.

于是对满足如下条件的安全设备的需求在持续增长：有着更长的贮藏寿命并且单个使用者可以容易地使用它。There is thus a continuously increasing demand for a safety device which has a longer shelf life and which can be easily used by a single user.

因此本发明的总目的就是克服或者至少改进一个或者多个上面所描述的缺陷。It is therefore a general object of the present invention to overcome or at least ameliorate one or more of the disadvantages described above.

参考附图，装置(1)包括一个保存所需液体配剂的容器(2)。容器(2)的典型容积是300ml。容器(2)的颈部(3)的外表面包括螺纹部分(4)。成型的内帽(5)包括一互补的螺纹部分(6)来咬合颈部(3)的螺纹部分(4)。一根两端(8，9)开口的导管(7)，与内帽(5)为一体并从内帽(5)延伸到接近容器(2)的底部。一个环绕内帽(5)外表面并位于它底端的第一凹部(10)(图2)。一个环绕内帽(5)外表面并大致位于帽(5)中部的第二凹部(11)(图3)。一个眼杯贮液器(12)，它包括形状与人眼眼眶相适应的上部(13)。管状的底部(14)从贮液器(12)的底部延伸并终止于一个内部隆起部(15)。内部隆起部(15)、第一凹部(10)和第二凹部(11)在形状上刚好互补。在眼杯贮液器(12)的上部(13)和底部(14)的连接处(16)，具有一个包括多个穿孔(18)的板(17)(图4和5)。眼杯贮液器(12)还包括一些排泄孔(19)。在连接处(16)下面是一切割刀刃(20)(图1和5)。当容器(2)装满所需的配剂后，一隔膜(21)(图1)密封住容器(2)的颈部(4)开口。一种合适的配剂是商业上可获得的0.9％的盐溶液，当隔绝空气密封后，它的贮藏寿命大约是3年。贴上隔膜(21)后，贮液器(12)安装到内帽(5)上，使得隆起部(15)容纳在凹部(11)内(图1和2)。在贮液器(12)上可以加一个帽子(图中未画出)，来防止灰尘之类在使用装置(1)之前进入贮液器(12)。然后整个装置(1)可以进一步封装在“热缩塑料包装”或类似的密封薄膜里。Referring to the drawings, the device (1) comprises a container (2) for holding the desired liquid formulation. A typical volume of container (2) is 300ml. The outer surface of the neck (3) of the container (2) includes a threaded portion (4). The formed inner cap (5) includes a complementary threaded portion (6) to engage the threaded portion (4) of the neck (3). A conduit (7), open at both ends (8, 9), is integral with the inner cap (5) and extends from the inner cap (5) close to the bottom of the container (2). A first recess (10) surrounds the outer surface of the inner cap (5) and is located at its bottom end (Fig. 2). A second recess (11) surrounds the outer surface of the inner cap (5) and is located approximately in the middle of the cap (5) (Fig. 3). An eyecup reservoir (12) including an upper portion (13) shaped to fit the orbit of a human eye. A tubular bottom (14) extends from the bottom of the reservoir (12) and terminates in an internal ridge (15). The inner raised part (15), the first recessed part (10) and the second recessed part (11) are exactly complementary in shape. At the junction (16) of the upper part (13) and the bottom part (14) of the eyecup reservoir (12), there is a plate (17) comprising a plurality of perforations (18) (Figures 4 and 5). The eyecup reservoir (12) also includes some drain holes (19). Below the junction (16) is a cutting edge (20) (Figs. 1 and 5). When the container (2) is filled with the desired formulation, a septum (21) (Fig. 1) seals the neck (4) opening of the container (2). A suitable formulation is a commercially available 0.9% saline solution, which has a shelf life of about 3 years when sealed from air. After affixing the septum (21), the reservoir (12) is mounted on the inner cap (5) such that the protuberance (15) is housed in the recess (11) (Figures 1 and 2). A cap (not shown) can be added on the liquid reservoir (12) to prevent dust and the like from entering the liquid reservoir (12) before using the device (1). The whole device (1) can then be further encapsulated in a "shrink wrap" or similar hermetic film.

装置(1)的所有组件可以由满足以下属性的塑料材料制成：(a)容器(2)的侧面可以被装置(1)的使用者向内折曲；以及(b)贮液器(12)的底部(14)能够弹性挠曲使得隆起部(15)可以从凹部(11)脱离并咬合凹部(10)。更好但不是必需的是，内帽(5)的颜色与其余组件的不同，这样可以从视觉上帮助区分装置(1)的开启和未开启状态。内帽(5)的一种合适的颜色是“安全黄色”。All components of the device (1) can be made of a plastic material satisfying the following properties: (a) the sides of the container (2) can be flexed inwardly by the user of the device (1); and (b) the reservoir (12 ) can be elastically deflected so that the raised portion (15) can disengage from the recess (11) and engage the recess (10). It is better but not necessary that the color of the inner cap (5) is different from that of the rest of the components, which can help to visually distinguish the opened and closed states of the device (1). One suitable color for the inner cap (5) is "safety yellow".

当使用时，一只手拿着容器(2)同时另一只手紧握住贮液器(12)然后拧或者向下压直到隆起部(15)咬合凹部(10)(图3)。通过这个操作，刀刃(20)刺穿隔膜(21)。除去贮液器(12)防灰尘的帽子。然后把贮液器(12)放在染病的眼眶上，通过挤容器(2)的侧面，流体可以通过导管(7)经板(17)流到贮液器(12)内来洗眼睛。当流体通过穿孔的板(17)向上喷射时，使用者的头部只需向前倾斜，而不是向后倾斜。所有不用的或已这样用过的流体通过排泄孔(19)排到容器(2)的外部，因此消除了冲洗时被污染的流体回到眼睛的可能。如果内帽(5)具有与周围组件不同的颜色，贮液器(12)的尺寸可以调整为，当装置(1)处于“未开启”或准备使用的位置时，内帽(5)从中部到底部的部分清楚可见，而当装置已经被开启使用时，贮液器(12)的底部(14)遮蔽住从中部到底部那部分使之不可见。When in use, hold the container (2) with one hand while holding the reservoir (12) firmly with the other hand and twist or press down until the ridge (15) engages the recess (10) (Figure 3). By this operation, the blade (20) pierces the septum (21). Remove the dust cap from the reservoir (12). Then liquid reservoir (12) is placed on the eye socket of infecting, by squeezing the side of container (2), fluid can flow in liquid reservoir (12) by conduit (7) and wash eyes through plate (17). As the fluid is sprayed upwards through the perforated plate (17), the user's head need only be tilted forward, not backward. All unused or thus used fluid is drained to the outside of the container (2) through the drain hole (19), thus eliminating the possibility of contaminated fluid returning to the eye during flushing. If the inner cap (5) has a different color than the surrounding components, the reservoir (12) can be sized so that when the device (1) is in the "unopened" or ready-to-use position, the inner cap (5) The part to the bottom is clearly visible, while the bottom (14) of the reservoir (12) hides the part from the middle to the bottom from view when the device has been opened for use.

于是本发明的装置可以提供一个完全装配好的设备，它装满合适的配剂，并且立即能够在开始清洗眼睛之前喷射药水到眼眶周围来冲掉刺激物。作为一个密封机构，配剂药水在很长的贮藏寿命期间始终保持不受污染，不需要经常监测它的适用性，并且它能被单个人开启和使用。如果认为需要的话，在使用后可以丢弃整个装置或者消毒后再次填充药水并密封供以后使用。本发明的一个特别重要的优点是使用时不必象现有技术装置那样要倒过来以便靠重力来供给冲洗配剂。The device of the present invention can then provide a fully assembled device, filled with the appropriate formulation, and immediately capable of spraying the solution around the eye sockets to flush out the irritant before beginning to wash the eyes. As a sealing mechanism, the dosing potion remains uncontaminated over a long shelf life, does not require constant monitoring of its suitability, and can be opened and used by a single person. If deemed necessary, the entire device may be discarded after use or sterilized and refilled with a solution and sealed for later use. A particularly important advantage of the present invention is that it is used without having to turn it upside down to feed the flushing formulation by gravity, as with prior art devices.

要强调的是上面所描述的实施例只是本发明各个方面的一个范例，可以作出各种修改和变更而不偏离在以下权利要求中定义的本发明基本原理。It is emphasized that the embodiment described above is only an example of various aspects of the invention, and that various modifications and changes may be made without departing from the basic principles of the invention as defined in the following claims.
