Embodiment Construction

[0019] In the figures, identical elements and / or elements having the same function have the same reference signs.

[0020] figure 1 A filling device 100 for dispensing and / or dosing a medicinal liquid 1 into a medicinal container 2 such as an ampoule, vial or the like is shown in a highly simplified illustration. The medicinal liquid 1 is especially a liquid 1 with low viscosity or relatively low surface tension, or a liquid capable of creeping, especially an oil-based or alcohol-based liquid.

[0021] The filling device 100 comprises a product storage tank 101 for the liquid 1 in which the liquid 1 is stored, for example at a certain positive pressure P. A plurality of filling tubes 102 protrude from the product storage tank 101 and each filling tube 102 is connected to a filling needle 10 according to the invention, for example using a piston metering device 105 connected therebetween. The piston metering device 105 is designed to deliver a certain amount of liquid 1 in th...

Abstract

The invention relates to a filling needle (10; 10a-10g) for dispensing a medicinal liquid (1) into a container (2), comprising a preferably pin-shaped filling needle body (12; 12a; 12b; 12d; 12f 12g), a product supply hole (13) is formed in said filling needle, said filling needle has at least one, preferably a plurality of product outlet holes (16; 16a-16d), said product outlet holes (16; 16a -16d) extends from the product supply hole (13) and is aligned with the filling needle end (25; 25b; 25c) with respect to the longitudinal axis (18) of the filling needle (12; 12a; 12b; 12d; 12f; 12g) The outer wall of the filling needle body (12; 12a; 12b; 12d; 12f; 12g) is opened in a spaced area, and the filling needle has a valve element (14; 14b; 14c; 14d; 14e; 14g), the The valve element is made of elastic material and covers the filling needle (12; 12a; 12b; 12d; 12f; 12g) at least in the region of the at least one product outlet opening (16; 16a-16d).

Description

technical field [0001] The invention relates to a filling needle for dispensing a medicinal liquid into a container and to a filling device having at least one filling needle according to the invention. Background technique [0002] Fill needles are commonly used to dispense or dose pharmaceutical liquids into containers such as ampoules, vials, and the like. The filling needles can be arranged on the filling device in such a way that they can be raised and lowered in order to dip, for example, into the head region of the drug container. The filling needle is also connected to a product storage container for the medicinal liquid via a filling tube. Carried out by subjecting the medicinal liquid in the product storage container to a positive pressure and arranging a valve device, for example in the form of a pinch valve, in the region of the filling needle and / or in the region of the filling tube arranged between the filling needle and the product storage tank The practice ...
