Embodiment Construction

[0043] The spraying device 1 shown in Figures 1 and 2 comprises a liquid reservoir 2, a confinement bell 3, a spraying unit 4, a porous pad 5 and a fixing ring 6 (Figure 2).

[0044] The reservoir 2 is slidingly mounted relative to the cover 3 and comprises a body 10 and a cover 11 of plastic.

[0045] The body 10 has a first cylindrical portion 12 , a second cylindrical portion 13 , an annular collar 14 and two legs 15 .

[0046] The cylindrical portion 12 defines a housing 17 closed by a cap 11 for storing reagents.

[0047] The cylindrical portion 13 is located in line with the portion 12 on the opposite side of the cover 11 , and the outer diameter of the cylindrical portion 13 is smaller than that of the portion 12 .

[0048] A threaded portion 16 is formed near the opposite end of the cylindrical portion 13 to which the portion 12 is connected.

[0049] A collar 14 is connected transversely to the rest of the body at the junction of the cylindrical parts 12 and 13 .

Abstract

The device for spraying a reagent onto a support (81) adapted to retain microorganisms on a predetermined surface (82), comprises a spraying bell (3) as well as a nozzle (71) for emitting a jet of droplets of said reagent into a spraying chamber (34) comprised by said bell (3), said device also comprising an absorbent pad (5) mounted against said bell (3) transversely to said jet and closing said chamber (34) from the opposite side to said nozzle (71) with the exception of a circular central opening (51) provided in said pad (5), the diameter of said central opening (51) being adapted to enable a portion of said jet, when said device faces said support (81) and is at a predetermined distance therefrom, to pass through said central opening (51) over its entire area and be deposited on the whole of said predetermined surface (82) of said support (81).

Description

technical field [0001] The present invention relates to spraying devices for rapid microbiological analysis. Background technique [0002] Currently, stringent standards must be complied with for checking the microbiological quality of liquids, gases or surfaces in the context of industrial and medical activities. [0003] With this in mind, industry personnel and health authorities should have at their disposal the tools to detect microbial contamination as quickly as possible so that it can be corrected promptly and cost-effectively. [0004] In fact, microbiological monitoring is done on a gel growth medium, where the microbes, after having been collected on a microporous membrane, are cultured until they are already visible to the naked eye. [0005] The incubation period varies from one microorganism to another, but is generally at least 24 hours, longer for slow growing microorganisms such as mycobacteria or because the microorganism has been stressed by environmental...
