Title:
DOSING APPARATUS AND INJECTION DEVICE
Document Type and Number:
WIPO Patent Application WO/2017/211851
Kind Code:
A3
Abstract:
The invention relates to a dosing apparatus (20) for the, in particular, subcutaneous delivery of a fluid. The dosing apparatus comprises a conveying device (21) for conveying the fluid out of the interior space of a container. The fluid can be conveyed by means of the conveying device (21) from the container to a dispensing opening (24). In addition, an injection device (1) for the subcutaneous delivery of a fluid is disclosed. The injection device (1) comprises a piercing cannula (2) and an indwelling cannula (3), wherein in a starting position a distal end area of the piercing cannula (2) extends coaxially in the interior of the indwelling cannula (3). The device (1) comprises a first and a second rotor (4), (5) which are mounted in a displaceable manner. The first rotor (4) is connected to the piercing cannula and the second rotor (5) is connected to the indwelling cannula. The device (1) further comprises a control element (6) that can be moved over a predefined control area. The control element (6) can be brought in operative connection with the first rotor (4) and the second rotor (5) for the displacement thereof. The control element (6) is designed in such a manner that it causes in a first part of the control area a rectified, in particular simultaneous displacement of the two rotors (3), (4), and thus a placement of the indwelling cannula. In a second part of the control area, the control element (6) is designed in such a manner that it causes a blocking of the second rotor (5) and thus a holding of the indwelling cannula (3) in a dwell position, as well as a back movement of the first rotor (4) and thus a withdrawal of the piercing cannula (2) from the distal end region of the indwelling cannula (3) into an end position.
