- the containment assembly according to the invention which is designated in its entirety by the reference I, is intended to equip a contaminated room or one likely to be contaminated.
- room 100 is a hospital room.
- the assembly according to the invention can be fitted to other types of hazardous parts, within the meaning of the definition given in the introductory part of this description.
- These high-risk rooms can in particular consist of conventional premises, such as offices or classrooms. Such premises will be used to accommodate patients who are at least potentially contaminated, by being consequently diverted from their usual use.
- This chamber 100 comprises, in a manner known per se, a floor 102, a ceiling 104, a glazed partition 106 as well as blind partitions, only one of which 108 is shown in the figure. Furthermore, a partition 110 allows communication between this chamber 100 and the corridor 130. For this purpose, this partition is hollowed out with an opening, at the periphery of which extends a frame 120, allowing the articulation of a door. 'inlet 122.
- the chamber 100 is moreover equipped with various medical devices of conventional type, which will not be described in more detail in what follows, such as in particular a bed 124.
- the containment assembly I according to the invention comprises everything first an airlock 1, which comprises a frame 10.
- This frame 10 supports different walls of the airlock, namely first of all a lower wall 11 and an upper wall 12, as well as opposite side walls 13 and 14.
- the opposite walls 15 and 16 are provided with respective slides 17 and 18, for example of the zipper type. In their closed position, these slides 17 and 18 define a closed interior volume V1 of the airlock, which is sealed. Furthermore, in their open position, these slides 17 and 18 define passages 19 and 20, allowing a user to pass through the aforementioned walls 15 and 16.
- the airlock 1 is made of any suitable material, advantageously treated for protection against fire.
- the material constituting the airlock is flexible in nature, which allows easy adaptation of the containment assembly according to the invention to parts of different geometries.
- polyvinyl chloride (PVC) with a thickness of around 0.3 to 0.5 millimeters can be used.
- the containment assembly I further comprises a skirt, designated as a whole by the reference 3.
- This skirt is fixed by any suitable means, advantageously by welding, at the rear wall 15 of the airlock.
- This skirt delimits a tunnel 4, which is bordered by respectively lower 31, upper 32 and opposite side walls 33 and 34. This tunnel is open in two opposite directions, both towards the front in the direction of the wall 15 and towards back towards the main corridor 130.
- the material constituting the skirt 3 is identical to that of the airlock 1. Furthermore, also advantageously, the skirt is flexible in nature. Referring to Figure 2 this means that, typically, this skirt has a possibility of significant rotational movement in two opposite directions, relative to the longitudinal axis X1 of the containment assembly.
- the skirt 3 is provided with a crown 42, intended to be pressed against the rear face 111 of the partition 110, at the periphery of the frame 120.
- This crown 42 which has an overall U shape , has an upper core 43, as well as lateral wings 44.
- the outer periphery of this core and of these wings is bordered by a frame, which is intended to receive an adhesive 45.
- This adhesive 45 is advantageously produced in the form of an adhesive strip, reinforced with fibers.
- a rod 46 is provided, advantageously of the nature telescopic, which provides a mechanical prop function between the side walls 33 and 34 of the skirt.
- the crown 42 also has a flap 47, which in use forms a horizontal threshold providing sealing at the interface between the partition and the ground.
- This threshold 47 consequently extends, towards the rear, both the lower wall 31 and the wings 44.
- this threshold 47 comprises in particular a base 48, made in the form of a solid plate of a rigid material and dense, typically stainless steel, the thickness of which is for example 5 mm.
- This base 48 ensures, in cooperation with the support rod 46, satisfactory mechanical stabilization of the skirt 3.
- the containment assembly according to the invention further comprises an extraction member, designated as a whole by the reference 5.
- the latter consists first of all of a hollow body 50, of generally parallelepipedal shape.
- This hollow body is supplied with air by an inlet connector 52, which is introduced into an orifice 36 formed in one of the side walls of the skirt 3.
- Means, not shown, of any known type, provide the seal between the walls facing this orifice 36 and this connector 52.
- this hollow body supplies an outlet connector 54 with air, which is in communication with a suction and filtration unit 6, which will be described below .
- the hollow body 50 has a small footprint, in the transverse direction Y1 of the containment assembly. Consequently, and also thanks to its rigid nature, this hollow body allows easy transit in the confined tunnel, for example for a bed or a wheelchair. It will also be noted that this hollow body can fulfill an additional function, namely to allow the passage of measuring or sampling tools.
- Unit 6 first of all comprises a connection plenum 60, which is equipped with an inlet fitting 62.
- the latter is capable of being placed in communication with the outlet fitting 54 of the extraction member. , typically by a pipe which is not shown in the figures but whose path is shown by dotted lines 56.
- This connection plenum 60 is placed next to a filter 64, of any suitable type, itself adjacent to one or more suction fans, not shown in the figures but shown by the dotted lines 66.
- These fans allow the air to exit from the unit 6, via outlet means.
- these means are formed by an outlet grille of the fan, which is assigned the reference 68.
- This unit 6 is also provided with a control 70, of any suitable type, which will not be described in more detail in what follows. As shown in particular in Figure 6, this control is 2 means equipped with gauges 72. These make it possible to display the value of the pressure cascades between, on the one hand, the clean corridor 120 and the airlock 1 is, on the other hand. share, between this airlock and room 100.
- the containment assembly according to the invention is finally provided with means, allowing controlled admission of air into the interior of the room 100.
- two registers 80 and 82 are provided, the structures of which are identical. These registers are integrated into the front and rear walls of the airlock, respectively.
- each register is movable between a closed position, in which it prevents the passage of air between the spaces which it delimits, as well as an open position in which it allows this passage of air. in a single predefined direction. Therefore, in the case of the present invention, each damper first prevents the passage of air in the unwanted direction, from the chamber to the airlock, as well as from the airlock to the confined tunnel.
- each register allows the passage of air, in this one direction chosen, only when the predefined nominal pressure is reached.
- registers 80 and 82 have a predefined nominal value. In other words, they allow the passage of air only beyond a predefined pressure difference.
- registers also of a type known per se, for which the nominal value is adjustable.
- the nominal values V 80 as well as V 82 of these registers are typically equal. By way of non-limiting examples, each of these nominal values is between 5 and 15 Pascal.
- the peelable resin type is advantageously used.
- This resin is applied to the areas of the partitions, liable to promote air transit with the outside. This external transit can take place, not only in the direction of the corridor, but also in the direction of the adjacent rooms.
- the airlock frame is then inflated, in a conventional manner.
- the skirt is deployed in the direction of the door frame, the crown being applied against the external face of the partition 110, as described above.
- the adhesive 45 is placed.
- unit 6 is started up. Consequently, air is extracted in the direction of this unit 6, through the intermediary of the extraction member 5, which is materialized by the successive arrows F5 and F6 in FIGS. 8 to 10. This air is filtered, then returned to the corridor at the level of the outlet means 68, which is materialized by the arrows F 68 in these figures 8 to 10.
- An operator OP visible in Figure 1, can then pass through the corridor 4, then enter the airlock 1 and finally the chamber 100. This operator is likely to put in work, safely, the appropriate spots within that room.
- the registers 80 and 82 are closed, which prevents any passage of air, as shown by the crossed out arrows F80 and F82 in FIG. 8. Consequently, we understand that the pressure inside the chamber then tends to decrease. In other words, this chamber is at a depression relative to the confined tunnel. When the value of this depression reaches a predetermined threshold, air is admitted into the room from the confined tunnel, via the successive registers 80 82.
- FIG. 9 there is first of all opening of the register 80 separating the room and the airlock. An air passage then occurs, in one direction, from the airlock towards the room, which is materialized by the arrow F'80. Then, as shown in Figure 10, there is then opening of the register 82 separating the tunnel and the airlock. The air can therefore flow, in one direction, from the tunnel to the airlock, which is materialized by the arrow F'82. Once these two registers are open, there is therefore admission of air, in a single direction, from the confined tunnel 4 to the room at risk 100.
- the predetermined threshold between the internal pressure of the room 100 and the internal pressure of the confined tunnel 4, beyond which there is controlled admission of air into the room, is equal to the sum of the two predefined values V80 and V82, which relate to registers 80 and 82 mounted "in series". As seen in the above, each of these values is between 5 and 15 Pascal, so the predetermined threshold above is between 10 and 30 Pascal.
- registers 80 and 82 are held in their open position. On the other hand, these registers close each time the passages 19 and 20 are opened, in the vicinity of which they are located. This helps to minimize the effects of compression and relaxation, which are associated with these opening phases.
- the invention has many advantages over the prior art described in the preamble of the pending description.
- the containment assembly in accordance with the invention first of all provides effective protection for the personnel responsible for carrying out operations in the room at risk. Indeed, the combination between, on the one hand, the suction and filtration of air coming from the room at risk and, on the other hand, the controlled admission of clean air into this same room, guarantees particularly containment. satisfactory contamination.
- the assembly according to the invention benefits from a reduced footprint. Therefore, this allows its installation in small rooms. In addition, this small footprint ensures conservation of medical equipment, as well as their original function. It will also be noted that the assembly according to the invention can lend itself to an implementation of the reversible type. In fact, once the contamination containment phase has been carried out, the various mechanical elements making up this containment assembly can be dismantled and then extracted from the part to be treated, in a simple manner.
- the assembly according to the invention can be installed quickly within the room at risk. This is particularly interesting in the case of an epidemic-type episode, for which it is necessary to equip a large number of rooms, in order to accommodate a large number of patients who are at least potentially contaminated.
