- the combination 24 also comprises a first and a second leg section 24C and 24D, substantially tubular for accommodating the legs of an operator, connected to one another by an opening comprising a closure means 26 in a zone d crotch, for example a zipper, preferably along each first and second leg section 24C and 24D.
- a basin section 24E for accommodating the basin of an operator the basin section 24E is connected to the two sections of legs and ends at the opposite by a section of size 24F.
- Combination 24 also includes a top portion including a first and a second handle section 24G and 24H each connected to a trunk section 24I including the head passage section 24J.
- the head passage section 24J is connected to its hood 24K.
- Each aforesaid section may be formed of a single piece or of several pieces sewn together. Identically, several sections can be formed of one piece or of several pieces sewn together.
- the combination 24 comprises a first gripping means 25, in contact with the inner face in the body portion.
- Figures 12A-12F illustrate the user after donning the aseptic combination of the system according to the invention.
- the first air intake interface 2A is located on the aseptic combination 24, more particularly the user grasps the gripping means 13 which extends transversely relative to the main wall 2B in contact with the medium. surrounding the clean room, after gripping the gripping means 13, the user will push the first air intake interface 2A so as to allow the interlocking of the two tubes 8 and 8 'to allow the passing surrounding air from the surrounding air inlet ports 3 to at least one surrounding air outlet port 32 located within the aseptic combination 24 to allow breathing of the user.
- the first air intake interface 2A can, alternatively, be positioned on both the left and right sides of the aseptic combination 24 and on the front, side or back portion of the aseptic combination 24 as well. the aseptic combination 24.
- the combination 24 comprises a hood connected to the head passage section provided with goggles, such as those described in EP3318144, EP3223916, and EP2823859.
- the hood is also equipped with a wall intended to cover the nose and mouth in a filter material, allowing the gaseous molecules to easily exit but whose porosity retains the microorganisms that can be expelled by the operator's breathing.
- FIG. 13 illustrates a variant of the second interface 20, in fact the second interface 20 is in the form of a second longitudinal hollow body 18 having at least one series of air outlet openings 32.
- This second hollow body longitudinal is provided with an opening 30, optionally provided with a pipe 29, arranged to connect the steering means 17 of the surrounding air, possibly by means of an additional connection, and also comprises a collar 21 provided with a peripheral groove 21 A intended to house a seam of the subassembly, preferably said second longitudinal hollow body is sewn on a trunk section, preferably a section of thorax or collar, in all cases a section under the head of the underside of the user as shown in Figure 16.
- the second interface 20 having a shape of second longitudinal hollow body is particularly it is adapted to provide a comfortable surrounding air flow to the user, not straining the mucous membranes and preserving the quality of the air exchange with the clean room.
- FIGS. 14 and 15 illustrate variants of the attachment of the ventilation device 1 to the under-holding of a user
- the device 1 can be fixed, possibly by means of a connector 16, a harness or a type of backpack system that the user wears directly on himself or door for example on the sub-holding.
- the steering means 17 of the surrounding air is in the form of two pipes arranged to direct the surrounding air to the under-head section of the user by his back. Indeed, the two pipes of the steering means 17 of the surrounding air will pass through the back of the user, and each of the two pipes will be connected to a room 27 allowing the diffusion of the surrounding air to the user for his breathing.
- the hollow body 18 is integral with the subassembly 23, for example fixed at the shoulder of the subassembly 23.
- the hollow body 18 may also be integral with the steering means 17 of the surrounding air .
- the hollow body 18 may be in the form of a surrounding air outlet diffuser in an internal part of the aseptic combination 24, this diffuser being provided with an air outlet orifice 31, comprising at least a series of air outlet openings 32.
- the first air intake interface 2A is made of thermoplastic polyurethane and / or rubber based on a nitrile group, preferably of butadiene- ⁇ -acrylonitrile copolymer.
- the surrounding air of a clean room can be substituted by breathable air from a compressed air cylinder, provided for example with a regulator, as in situations where the air is contaminated.
- a compressed air cylinder provided for example with a regulator
- said subunit may be a sublayer of the combination.
- said air intake means may be connected to a portable type outdoor air filtration system other than a venting device.
