Device with display for repeated dosing

摘要

A dosing device comprises a housing. The housing has a slot-shaped opening in the axial direction. The respective region of a setting cylinder located inside the housing can be seen from the exterior through the opening. The setting cylinder can be radially rotated or set by way of a setting wheel. Quantitative indications of the discharge volumes for various syringe types at various settings are arranged in columns on the setting cylinder in the form of a table. The cylinder is oriented relative to the window in the housing such that at a given angular setting of the cylinder the correct discharge volume is visible in the window for every syringe type.

1. A device for dosed dispensing of a medium from a container, which comprises a plunger, by depressing the plunger, and comprising:
a housing; a dispensing mechanism with a dispensing element; an actuating element, which can be moved from a first stop to a second stop, wherein the actuating element is coupled to the dispensing element, such that, upon movement of the actuating element from the first stop to the second stop, the dispensing element depresses the plunger by a distance; a setting mechanism adapted to set the distance travelled by the dispensing element for every movement of the actuating element from the first stop to the second stop, wherein the setting mechanism can be set in steps by rotation of a setting element and has at least a cylindrical wall section; and a display element that includes: a slot-shaped opening in the housing through which a slot-shaped portion of the cylindrical wall section can be seen from outside the housing, wherein the slot-shaped opening is arranged relative to the cylindrical wall section such that, for a given setting step of the setting mechanism, a corresponding dispensed quantity per actuation of the actuating element can be seen for each type of container, and information on one or more container types or information on one or more properties of the one or more container types is located beside the slot-shaped opening at the housing; and a tabular list of one or more quantities that are dispensed upon movement of the actuating element from the first stop to the second stop for a predetermined number of different types of containers at various step-like settings of the setting mechanism, wherein the tabular list is arranged on the cylindrical wall section, one or more columns of the tabular list each specify the dispensed quantity per actuation of the actuating element for the different types of containers at a particular setting of the setting mechanism, and one or more rows of the tabular list specify the dispensed quantity for a particular type of container at the various step-like settings of the setting mechanism.
