    • A hand-held device (1) for dispensing a metered quantity of a substance such as a pharmaceuticals, medicinal, or therapeutic substance, and applying that substance to the skin of a host animal. The device (1) includes a hollow body (2) that can be grasped by the hand of a user, and a substance capsule (4) mounted within that body. The capsule (4) includes a container (5) for the substance, and a nozzle (10) through which a quantity of the substance is dispensed, possibly in the form of a spray. The device (1) also includes actuator means (6,9) connected to the interior of the substance container (5) and operable to cause a metered quantity of the substance to be dispensed through the nozzle (1). The actuator means (6,9) may include a manually operable pump (6), or it may include a valve that is selectively operable to prevent or permit pressurized contents of the container (5) escaping in the form of an aerosol. In the former case, the pump (6) may be operated through an actuator button (9), and in the later case the valve may be opened through operation of an actuator button (9). The device (1) also includes means for preventing or minimising unintentional loss of the stored substance. In one form, that means includes a closure member (2) that is operable to close or open the nozzle outlet. In another form it includes an absorption pad (31) onto which an initial quantity of the substance is deposited, and which is thereafter removed to permit normal operation of the device (1). If a closure member (20) is used, means may be provided to apply a force to that member so as to ensure effective closure of the nozzle outlet. Substance emerging from the nozzle (10) is received within a shroud (13) for confining the dispensed substance to a designated target area, and which may also function to position the nozzle (1) at a suitable distance from the target area.
    • 一种手持装置(1),用于分配计量的物质如药物,药物或治疗物质,并将该物质施加到宿主动物的皮肤上。 该装置(1)包括可由使用者的手抓住的中空主体(2)和安装在该主体内的物质胶囊(4)。 胶囊(4)包括用于物质的容器(5)和喷嘴(10),通过该喷嘴可以喷射一定量的物质。 装置(1)还包括连接到物质容器(5)内部的致动器装置(6,9),其可操作以使计量量的物质通过喷嘴(1)分配。 致动器装置(6,9)可以包括可手动操作的泵(6),或者其可以包括可选择性地操作以防止或允许容器(5)的加压内容物以气溶胶形式逸出的阀。 在前一种情况下,泵(6)可以通过致动器按钮(9)来操作,并且在随后的情况下,阀可以通过致动器按钮(9)的操作而打开。 装置(1)还包括用于防止或最小化储存物质的无意损失的装置。 在一种形式中,该装置包括可操作地关闭或打开喷嘴出口的关闭构件(2)。 在另一种形式中,它包括吸收垫(31),在其上沉积初始量的物质,并随后将其移除以允许装置(1)的正常操作。 如果使用封闭构件(20),则可以提供用于向该构件施加力的装置,以确保喷嘴出口的有效封闭。 从喷嘴(10)中出来的物质被接收在护罩(13)内,用于将分配的物质限制在指定的目标区域,并且还可以起到将喷嘴(1)定位在离目标区域适当距离的作用。
