Problems solved by technology

[0004] However the device described above has a number of disadvantages
Firstly, keeping the two substances contained in separate containers separated is a complex operation in the known devices; the known devices therefore do not guarantee an optimal separation of the two substances
This disadvantage is particularly disadvantageous because when the mixing of substances takes place at the wrong moment, it may result in the wrong preparation of the solution intended to be dispensed by the device

Embodiment Construction

[0120] Referring to the figures, 1 generally indicates a droplet dispensing device. The droplet dispensing device 1 comprises a first container 2 , a second container 3 , a spacer 4 and a dispensing member 5 . Preferably, the first container 2 is integrally formed. The first container 2 comprises a base 6 containing water for injection (WFI) 200 or a water-based solution for injection. The base 6 has a support base 7 and an upstanding wall 8 from which a tubular element 9 extends transversely. The tubular element 9 is integrally formed with the base 6 and has an open end 10 . The tubular element 9 also has mechanical connection means 11 designed to allow the first and second containers 2 , 3 to join. By way of example, the tubular element 9 may have a first section, which is substantially smooth and intended to receive the spacer 4 , and may define mechanical connection means 11 along a second section of the tubular element 9 . The mechanical connection means 11 may compri...

Abstract

The present invention relates to a method for the preparation of an eye drop dispensing device (1). The method comprises the steps of: - providing a first container (2) and a second container (3) configured to engage in a fluid-tight manner, - providing a separation Parts (4), - introducing the water-based solution (200) in the first container (2), - introducing the solution or dispersion containing the drug in the second container (3), - placing the spacer (4) at the second between a container and a second container (2, 3), - engaging the second container (3) and the first container (2) in a fluid-tight manner; and - lyophilizing the solution or dispersion containing the drug.

Description

technical field [0001] The present invention relates to a device for dispensing eye drops, a method for preparing an device for dispensing eye drops and a method for preparing multi-dose eye drops. In particular, the present invention relates to dispensing devices for eye drops comprising a first substance and at least one second substance comprising a therapeutic agent. Background technique [0002] Droplet dispensing devices are known. Known droplet dispensing devices typically have a body and a dropper coupled to the body. The purpose of the dropper is to allow the administration of the substance contained within the dropper at the time of dosing, thereby simplifying the dispensing of a predetermined amount of liquid droplets. [0003] There are also known devices designed to contain two different substances in separate containers. These containers may be configured to prevent mixing of two substances or to allow mixing, for example for preparing a solution. [0004] ...
