Problems solved by technology

Therefore, it is observed that this support has the effect of uncontrolled spreading of the existing jet stream to the detriment of its correct uniformity
In order to overcome this disadvantage to the greatest extent, the support is made as thin as possible, but this makes it particularly vulnerable to impacts and other stresses it experiences during use, not to mention that it is placed on the top of the device and further increases the this vulnerability

Embodiment Construction

[0037] figure 1 Shown is a fractionation syringe 1 according to the invention, formed by a cylindrical body with a longitudinal axis xx' and whose front face 1a has a smaller diameter. The syringe 1 is traversed from one side to the other by a Venturi-type longitudinal flow line, which consists of three parts, specifically, a converging part 3, followed by a cylindrical part 5, and thereafter extending to a diverging part leading to the outside 7.

[0038] In this embodiment of the invention, the aperture of the converging portion 3 is 46° and the diameter of its inlet orifice is 4.78 mm. The diameter of the cylindrical part 5 of the extending converging part 3 is 1.3 mm and the diverging part 7 of the extending converging part has a hole of 15° and an outlet orifice of 2.27 mm.

[0039] Furthermore, the converging portion 3 and the diverging portion 7 have their respective axes coincident with the longitudinal axis xx′ of the syringe 1 . For its part, the cylindrical porti...

Abstract

The invention relates to a fractioning injector in particular for a Venturi-type mist generation device, comprising a main vein successively comprising an axial convergent vein (3) for receiving a pressurised gas flow, a cylindrical vein (5) and an axial divergent vein (7), said injector further comprising a substantially transverse secondary vein (9) for a liquid flow inlet and opening downstream from the convergent vein (3), characterised in that the axis (zz') of the cylindrical vein (5) is angularly offset relative to the longitudinal axis (xx') of the convergent (3) and divergent (5) veins. The invention also relates to injection devices and to mist generation apparatuses using such an injector.

Description

technical field [0001] The present invention relates to fractionated syringes, in particular intended to fit injection units of the type of syringes used on disinfection devices by means of the various devices and instruments contained on the surfaces to be treated, in particular on the walls of the rooms and in the rooms Above) disinfection products are atomized for disinfection. The invention also relates to a nebulizing device adapted to generate and spray fine droplets into the room to be treated, thereby forming a mist of the type known as "dry mist" in the room. Background technique [0002] It is known that germs that cause contamination and are suspended in the air of a room tend to lodge on the various surfaces and objects contained within the room. It is also known that, conversely, bacteriogens formed on objects and walls in rooms (for example, operating rooms, clean rooms, or various intensive care units, etc.) tend to form aerosols in the atmosphere. These roo...
