Problems solved by technology

[0006] However, the above solution has the disadvantage that it is not suitable for all forms of particulate matter
For example, particulate matter with limited free-flowing properties can adhere to clumps, which can lead to uneven distribution of the substance between different wells, i.e. some wells may not be filled with the desired amount of drug

Embodiment Construction

[0037] figure 1 with 2 Shown is a metering device 1 provided with a powder hopper 2 containing particulate matter such as powdered medicament (not shown). The powder hopper has a funnel-shaped interior and its inclined surface 12 is intended to direct powdered medicine (not shown) towards a plate 11 with a surface 3 which can be seen as forming the bottom of the powder hopper 2 . The surface 3 is shaped as a hole structure 4 with a recess 5 extending into the plate 11 . In this embodiment, the recesses are distributed in a circular pattern around the plate 11 . A filling device 13 is rotatably arranged in the center of the circular pattern of recesses 5 .

[0038] The filling device 13 comprises two filling members, which in this exemplary embodiment are two wheels 6 , and two scrapers 14 . Wheel 6 and scraper 14 are arranged at common boss 15 places. The drive shaft 16 is connected with the boss 15, so that the boss 15, the wheel 6 and the scraper 14 are rotatable. Such...

Abstract

The present invention relates to a dosing device (1) comprising a powder hopper (2) and a plate (11) with a surface (3), wherein said plate (11) is provided with at least one cavity (5) adapted for receiving a particulate material, and filling means (6) being movable along said surface (3) for moving particulate material into said at least one cavity (5), wherein said filling means (6) is adaptedto exert a compressing force on said particulate material in a direction towards said surface (3) so that said particulate material is forced into said at least one cavity (5). The present invention also relates to a method for filling the cavity provided in the plate of the dosing device with a quantity of particulate material.

Description

technical field [0001] The present invention relates to a dosing device comprising a powder hopper, a plate having a surface, wherein said plate is provided with at least one recess adapted to receive particulate matter, and movable along said surface for dispensing the particulate matter A filling member moved into the at least one recess. The invention also relates to a method of filling a recess provided in a plate of a metering device with a quantity of particulate matter. Background technique [0002] Today, the supply and distribution of drugs is accomplished in a number of different ways. In the field of health care, more and more efforts are focused on the possibility of metering medicines in powder form by means of dispensing devices, such as inhalation devices, and administering them directly to the lungs of the user to enable the administration of specific medicines. is efficient and user-friendly. In most cases some form of metering is used to prepare the dose...
