Liquid delivery device and method for operating ejecting device

一种用于朝眼睛喷出液流的装置和使用方法，该液流从一个近端位置朝向一个远端位置移动，该装置包括：a)一个壳体，b)一个用于该液体的容器，c)至少一个设置用于喷出液流并与该容器成液体连通的开口，d)一个可操作地从容器通过该开口输送至少部分液体以形成液流的泵机构，和e)一个具有一个设置用于和眼睛或其面部周围接触的接触表面的洗眼杯。该洗眼杯设置成可以相对于该开口或壳体在至少两个位置之间移动，所述位置为I)一个有效位置，在此上述洗眼杯接触表面离该开口有一个限定的安全距离，II)一个静止位置，在此洗眼杯接触表面在一个比在有效位置时更近端的位置，并且设置有一个传感器以允许在两个位置之间进行识别。该泵机构可以包括一个可以存储用以驱动泵机构的击发能量的泵驱动器，和至少一个可存在并可操作地启动用于液体输送的装置的致动机构，从而设置一个驱动机构以将手动或存储的能量转变为I)泵驱动器的击发能量，和II)用于致动机构的操作的直接或存储的能量。 A device and use method for ejecting a liquid stream towards an eye, the stream moving from a proximal position towards a distal position, the device comprising a) a housing, b) a container for the liquid, c) at least one opening arranged for ejection of the stream and being in fluid communication with the container, d) a pump mechanism operable to deliver at least part of the liquid from the container through the opening to form the stream and e) an eyecup with a contact surface arranged for contact with the eye or its facial surroundings. The eyecup is arranged movable with respect to the opening or housing between at least two positions i) an active position with said eyecup contact surface at a defined safety distance to the opening and ii) a rest position with the eyecup contact surface at a position more proximal than in the active position and a sensor is arranged to allow discrimination between the positions. The pump mechanism may include a pump driver able to store cocked energy for driving the pump mechanism and at least one activation mechanism may be present and operable to initiative the device for the liquid delivery, whereby a driving mechanism is arranged to transform manual or stored energy both i) into cocked energy of the pump driver and ii) into direct or stored energy for operation of the activation mechanism.
