Problems solved by technology

Consequently, a further operation, usually involving re-verticalizing the rod, is necessary, which proves to be relatively time consuming, cannot be automated, and can weaken the joint weld between the rod and the end face
[0016] Additionally, this design makes it difficult to achieve a welded rod / end face joint weld and a final finish operation, which is essential for a clean and safe pharmaceutical environment

Embodiment Construction

[0035] The invention relates to a fastening system designed to mechanically connect the metering pump 1 to a support (not shown in the figures). The metering pump 1 may consist of any device operable to fill a container with a predetermined amount (ie a dose) of a fluid substance such as a liquid, powder or paste. Preferably, the metering pump 1 is designed for metering a liquid, advantageously consisting of a pharmaceutical product intended to be ingested or injected into the patient. The metering pump 1 is thus advantageously constituted by a drug-type metering pump. As shown in the figures, the metering pump 1 has a generally elongated shape and extends longitudinally in the axial direction XX' (advantageously corresponding to the vertical direction) when it is mechanically connected to said support. As known in the art, this metering pump 1 advantageously comprises at least one piston 3 operating longitudinally, ie in the axial direction XX′. Advantageously, this meterin...

Abstract

The invention concerns a fixing system designed to mechanically connect a dosing pump to a support, said system comprising a lateral stop (9) designed to be mounted on the support and having an inner face (9A) and an outer face (9B), said system comprising a first hinge member (14) installed on said lateral stop (9), said system including an elastic fastener that comprises a flexible tab and a second hinge member designed to be able to engage with said first hinge member (14) such that said flexible tab is mounted rotatably on said lateral stop (9), between a locked position and an unlocked position.

Description

technical field [0001] The invention generally relates to the technical field of filling a container with a predetermined amount of a fluid substance, such as a pharmaceutical liquid substance, metered by means of a metering pump, such as a sealless volumetric pump. [0002] The invention relates more particularly to a fastening system designed to mechanically connect a metering pump to a bracket. The invention also relates to a method of manufacturing a fastening system designed to mechanically connect a metering pump to a bracket. The invention also relates to a unit consisting of: [0003] - a metering pump comprising at least one axially acting piston; [0004] - bracket; [0005] - and a fixing system designed to mechanically connect the metering pump to the bracket. Background technique [0006] Particularly in the medical field, it is known to fill containers, such as syringes or flasks, with fluid substances, such as liquid medicines, in precisely predetermined a...
