Problems solved by technology

[0003] However, although the measurement of stresses in classical planar components made of transparent materials, such as flat glass, is known, there is still a lack of such a method for measuring an article placed under compression, especially when the article has a complex shape. A reproducible method for the quantity of internal stresses in such articles made of transparent materials

Embodiment Construction

[0051] see figure 1 with 3 , which shows the support device 1 of the kit of the present invention, which enables an article having a longitudinal axis A (such as Figure 2a-2d Articles such as those shown in ) remain under longitudinal compression and enable rotation of the article.

[0052] exist Figure 2a Above, an article is shown having a generally tubular shape in the form of a syringe body 2 comprising a tubular barrel 3 having a longitudinal axis A, a proximal end 3a and a distal end 3b. The proximal end 3a of the tubular barrel 3 is provided with an outer flange 4 which provides a bearing surface for the user when injecting. The distal end 3b of the tubular barrel 3 is provided with a conical distal tip 5 providing a passage for the delivery of the drug contained in the tubular barrel 3 from the syringe 2 to the site of injection. The conical distal tip 5 is used to receive a needle (not shown).

Abstract

The present invention relates to a kit comprising a supporting device (1) for maintaining a transparent article (2) having a longitudinal axis A, a proximal end (3a) and a distal end (3b), said supporting device (1) including a proximal holder (10) including a port (14) intended to receive the proximal end (3a) of said article (2), and a distal holder (20) including a receiving part (24) intended to receive the distal end (3b) of said article (2), said port (14) and said receiving part (24) being aligned on the same longitudinal axis B, said supporting device (1) further comprising compression means (29) for putting said article (2) under longitudinal compression directed towards a center of said article, when said article is mounted on said supporting device (1) with its longitudinal axis A aligned on said longitudinal axis B, and a polarimeter. The invention also pertains to a method for measuring the stress inside an article made of transparent material.

Description

technical field [0001] The invention relates to a kit comprising support means for holding an article of transparent material in a substantially defined position under compression, and a polarimeter For measuring stresses in the material of an article when said article is mounted on said support means. The article can be a medical device, like a syringe body or an ampoule. The invention also relates to a method for placing articles of transparent material such as syringe bodies and / or cartridges and / or ampoules and / or vials under compression, and with such support means and polarimeters, In order, for example, to carry out further analysis of the preparation. Background technique [0002] Many medical devices are made of transparent materials such as glass, polycarbonate, polyolefins such as polyethylene, polypropylene, CCP (crystal clear polymer) or polystyrene. For such use as medical devices in the medical field, these medical devices must be generally safe and must no...
