Abstract

The present invention provides an apparatus comprising a flexible reservoir comprising first and second flexible foil portions sealed together to form an enclosed cavity adapted to contain a fluid, the reservoir having a pouch-like configuration defining a general plane, a needle-penetratable outlet being arranged on a portion of the reservoir which is inclined relative to the general plane. The apparatus further comprises a needle having a generally straight inlet portion and an outlet, the inlet being adapted to be arranged in fluid communication with the reservoir, wherein the needle and the reservoir are arranged moveable relative to each from an initial position in which there is no fluid communication therebetween and a connected position in which the needle inlet is arranged in fluid communication with the reservoir through the reservoir outlet, and wherein the needle in the connected position penetrates the reservoir outlet substantially in parallel with the general plane.

Description

technical field [0001] The present invention generally relates to a device comprising a reservoir for storing a fluid, the reservoir comprising an outlet allowing a fluid directing member, such as a lancet element, to enter the interior of the reservoir. In particular, such a reservoir can be designed to contain, in particular, medical liquid substances such as medicines, medicinal liquids, infusions, injections, dialysis fluids, perfusion fluids, chemical and nutritional fluids, human blood and its components, etc. Wait. Such a reservoir can also be used for other purposes, for example for storing calibration fluids for analytical equipment. Background technique [0002] In the disclosure of the present invention, the above-listed liquids in the form of medical liquids are mainly directed, however, this is only an exemplary application of the present invention. [0003] The medical liquid is usually contained in a reservoir (such as a container, bag or bottle), which can ...
