Device for removing fluids from vials

Abstract

The invention relates to a device for removing a fluid from at least one container (300), for example, from a vial, that has a seal that can be punctured. The device comprises a base body (210), in which a fluid channel is formed. In order to reduce the lost volume, a pin-shaped insertion element (250) that reduces the cross-section of the fluid channel is inserted into the fluid channel through an insertion opening. Locking structures (262, 263) that retain the container on the device in a removal position and in a storage position different therefrom can be provided so that the container can be stored on the device without the seal being punctured accidentally. Such a device can be used in particular to fill an applicator (100) having one or more fluid reservoirs from one or more vials.

Description

TECHNICAL FIELD[0001]The present invention relates to a device for removing a fluid from at least one container, more particularly from a container closed by means of a seal that can be punctured, e.g. a vial with a septum seal. In particular the invention relates to a device for filling an applicator with at least one fluid reservoir from one or more vials.PRIOR ART[0002]In many applications a mixture of two or more flowable components has to be produced and delivered at a predetermined mixing ratio. An example is the production of an adhesive for technical or medical applications, e.g. a fibrin-based medical adhesive. Another example is the production of a bone cement from several components using a monomer. There are also medicinal products, for example, which are produced by mixing two or more components, but are not storable when mixed. In this case it is desirable to initially store the components separately and only to mix them immediately before their administration. Similar...

AI Technical Summary

Benefits of technology

"The present invention provides an adapter-like device that allows for the removal of fluid from containers and the filling of applicators with the fluid. The device has a reduced dead volume, meaning that it minimizes the amount of fluid that cannot be used. It includes a basic body with an upper and lower side, in which a fluid channel with a constant or variable cross-section is formed along a longitudinal direction. The device also has an insert element that is inserted into the fluid channel and reduces the cross-section of the fluid channel in the area between the inlet and outlet openings. The insert element can be a peg or a flattened area. The device can be used as a filling device or an adaptor for filling reservoirs of applicators from containers. It has a connector for connecting the reservoir of the applicator to the outlet opening and a hollow needle-like puncturing element for puncturing the seal of the container."

Problems solved by technology

Similar problems are posed in other pharmaceutical or chemical systems comprising two or more components which are not stable in the mixed state.

However, it is often problematical to store flowable substances for a longer period in plastic applicators, as on the one hand the substances can chemically react with the plastic, and on the other hand there is a risk that gas, in particular oxygen from the air, can diffuse though the walls of the applicator or through seals and chemically modify the content.

The drawback of this is that the syringes have to be fitted with such an adapter or needles and necessarily require a certain distance which is predetermined by the diameter and distance of the vials.

However, the design of such a filling device is relative complicated: the device comprises two separately designed housing halves, which have to be connected to each other in order to form the connection area and the hood.

This results in a relative complicated manufacturing process and corresponding increased costs.

In addition the dead volume of such a device is relatively large.

This design requires a very precise fit and alignment of the two housing sections and is susceptible to defects.

This filling device also has a relative large dead volume.

However, known devices are generally not suitable for storing the vials directly on the device, as the accidental puncturing of the septum of a vial during transportation or handling cannot be ruled out.
