摘要:
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 initiate 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.
摘要:
A dispensing apparatus for a liquid product, the apparatus comprising a) a housing (2) or frame (3), b) a receptacle (4) for the liquid with a feed nozzle (4a) arranged substantially stationary with respect to the housing or frame, c) a dosing chamber (11) having an orifice (11a), d) a mechanism arranged to allow at least ejection of liquid through the orifice and e) a through passage (7) arranged to allow the ejected liquid to pass in a direction different from the feed nozzle or opening. The mechanism comprises a mobile element arranged movable with respect to the housing or frame between at least a first position in which the orifice of the dosing chamber and the feed nozzle or opening are in flow communication and a second position in which the orifice and the through passage are in flow communication and the mechanism is arranged to allow aspiration of liquid through the orifice when the mobile element is in the first position and ejection of liquid through the orifice when the mobile element is in the second position. A method for operating the device comprises the steps of i) connecting the orifice and the nozzle or opening in flow communication, ii) filling liquid into the dosing chamber through the orifice, iii) aligning the orifice with the through passage, and iv) ejecting liquid from the dosing chamber through the orifice.

摘要:
An injection device including a needle cover, a casing, an injection mechanism, and a needle holder including an injection needle, wherein the needle cover is carried by the casing such that it can be moved, against a restoring force, from a protecting position, past an injection position, and into an assembling position. In the protecting position, the needle cover extends beyond the skin penetrating tip of the injection needle and, in the injection position, the needle cover is short of the tip. In the assembling position, the needle cover allows access to the needle holder, whereby the needle holder can be gripped and connected to or detached from the casing.
摘要:
The present invention relates to a snap-type locking device for releasable and principally external keeping together of two parts (1, 2) and comprising at least one grip pat (11, 11a, 18, 20, 21, 22), at least one movable arm (12, 12a, 12b) and at least one spring (14, 14a, 14b, 14c), said at least one movable arm (12, 12a, 12b) being turnably attached to said at least one grip part (11, 11a, 18, 20, 21, 22) as well as, directly or indirectly, to a first part (1)of said two parts (1, 2). Said at least one spring (14, 14a, 14b, 14c) abuts against said at least one grip part (11, 11a; 18, 20, 21, 22) in order to urge the same in a direction away from said two parts (1, 2).
摘要:
An eye fluid applicator comprising a) a hand grip part having a distal end and a proximal end, the distal end and the proximal end defining a axis therebetween and a distal direction and a proximal direction along said axis, b) a container, or a seat for a container, having a bottle part and a delivery orifice for delivery of a stream or drops, the orifice defining a fluid delivery axis and a fluid delivery direction, along said axis, from the bottle through the orifice, the container being arranged with its orifice closer to the proximal end than the distal end, and c) an eye cup part having a rim and a cavity, the rim defining a contact plane, a contact axis normal to said contact plane and a contact direction, along said contact axis, from the cavity towards the rim, the eye cup being arranged at the orifice and the proximal direction of the hand grip and the contact direction of the eye cup forming an acute angle therebetween.
