Protective caps with pivoting attachment system for gas cylinders

Abstract

The invention relates to a protective cover (1) for a gas reservoir (10), comprising a cover body (2) forming a protective shell delimiting an internal volume designed to accommodate the entirety of the valve assembly or part thereof, the protective cover also includes an attachment means (3) pivotable between a plurality of angular positions, including a rest position and an attachment position in which the attachment The device is fully folded, and in the attached position, the attachment device is fully unfolded. The attachment device comprises a three-dimensional structure (3, 6a, 6b, 11a, 11b) comprising two arms (6a, 6b), each arm having a cutout (11a) for fixing to a support , 11b), said three-dimensional structure comprising an inner surface (13) shaped so as to follow the outer contour of the cover body of the cover when the attachment means are in a rest position. The invention also relates to a gas reservoir fitted with a valve assembly with or without a built-in regulator and fitted with the above-mentioned protective cover.

Description

technical field [0001] The present invention relates to a protective cap, also called a valve cap, for a cylinder, in particular a medical gas cylinder, fitted with means for attachment to a bed, stretcher, wheelchair, etc., said The device conforms (conforms, matches) the outer contour of the cover when folded to the rest position. Background technique [0002] Industrial and medical gases are usually packaged in gas receivers, usually cylinders, fitted with valve assemblies with or without built-in pressure regulators, i.e. simple on / off type valves or valves with built-in regulators , also known as a regulating valve, which allows control of the flow rate and pressure of the delivered gas. [0003] In order to protect the valve assembly, it is customary to place a protective cover on the neck of the cylinder and around said valve assembly, which forms a protective shell around said valve assembly. Such covers are commonly referred to as "bonnets". [0004] In addition,...

AI Technical Summary

Problems solved by technology

Although this makes it possible to prevent the arms from protruding beyond the cover body of the cover when folded, it has at the same time a significant disadvantage: the inside of the cover and the attachment means is more complicated to clean and can be damaged over time The unavoidable accumulation of dust and other dirt in the above-mentioned area of ​​the cover, i.e. resulting in a state of cleanliness that is slightly unsuitable for use in a medical environment

In addition, the pivoting arm is not necessarily easy for the user to manipulate, and the user's fingers may get caught when unfolding the pivoting arm and hooking the assembly on a support such as a bar of a hospital bed
