Description

The present invention relates to the field of clean rooms, in particular to protective equipment for a clean room and aseptic environment, particularly to clothing for a clean room and aseptic environment and even more particularly to a suit for a clean room and aseptic environment. By extrapolation, most of this protective equipment is also suitable for the medical and hospital environment.

The present invention also relates to a process for packaging protective equipment for clean rooms and aseptic environments according to the present invention.

The present invention also relates to a dressing method for covering protective equipment for a clean room and an aseptic environment according to the present invention.

• une face extérieure prévue pour être en contact avec le milieu environnant,
• une face intérieure agencée pour être en contact avec ou orienté vers un manipulateur.

The present invention relates more particularly to protective equipment for clean rooms and aseptic environments comprising:

• an outer face designed to be in contact with the surrounding environment,
• an inner face arranged to be in contact with or oriented towards a manipulator.

Such protective equipment is used in clean room environments, in laboratories, allowing for example to manufacture drugs or even biological, electronic or food material in an aseptic and sterile environment.

Clean rooms are notably used in many fields such as electronics, micromechanics, optics, nano and biotechnologies, pharmaceuticals, sterile masterful preparations in pharmacies, medical equipment or even in the food industry.

To ensure an aseptic and sterile environment in the laboratory and more particularly in the clean room, it must be built according to very strict standards. For example, the clean room must be supplied with a large amount of air filtered by high efficiency filters to dilute and remove particles, bacteria and chemicals inside the room. Air is also used to pressurize the room and ensure that no contaminated air enters the clean room.

In addition, the clean room must be constructed with materials chosen specifically as not generating contaminants, particles or chemical fumes and the materials must in addition be easy to clean.

Finally concerning the people, in other words the manipulators working inside the clean rooms, they must wear specific clothes, accessories, materials, tools to minimize the dispersion of the micro-organisms and the particles that they generate themselves such as hair, skin particles and clothing fibers.

For these reasons, in this type of room, it is necessary to isolate the body of the user so that he does not contaminate the environment in which he works or that he does not contaminate the product that he manufactures or on which he work.

The document WO2005065476 describes a protective or work suit used in dangerous conditions such as heat, fire, cold, ... The suit includes a pocket located on the thorax part of the operator's body. This pocket has two openings: an upper opening and a lower opening. The suit sleeves are tucked inside the pocket when the operator passes his hands through, first, the lower opening and, second, the upper opening to pull the sleeves inside the pocket through the top opening. The legs will then be lifted by the manipulator into the pocket via the top opening and the pocket closed.

When a manipulator has to work in such a sterile environment, he must, before entering the clean rooms, put on the various protective equipment for the clean room or aseptic environment, respecting a very specific protocol. Such procedures are very tedious and generally impose unconventional and very specific gestures and movements on the manipulator, for example the manipulator cannot touch any external face of protective equipment for a clean room or aseptic environment under penalty of contaminating this equipment. and therefore having to renew its dressing operation.

Unfortunately, a combination as described in the document WO2005065476 cannot be used in a clean room environment because it does not meet the criteria defining a clean room. It includes a variety of materials. In addition, the dressing procedure is difficult. The handler will not be able to don the suit without touching any outer face of the protective equipment when removing it from the pocket to don it.

In addition, protective equipment for clean rooms or existing sanitized environments are therefore sterilized and supplied in packaging which must be waterproof but which must also withstand autoclaving while on the one hand having to be easy to open for the manipulator before using it. enter the clean room and, on the other hand, strong enough to avoid tearing which could result in the contact of the protective equipment with a contaminated environment and therefore the subsequent introduction of contaminants into the clean room, the most of the time without the handler being able to realize it given the size of the contaminants.

Protective equipment for clean rooms or aseptic environments is typically packaged in packaging with lid, sterilized and individual but disposable, in other words single-use, which represents a significant source of waste. However, in a clean room or aseptic environment, everything that enters must come out and be treated. The current trend, given the current climate challenges is to reduce disposable packaging and associated waste without harming the sterility of the whole.

There is therefore a real need to provide protective equipment for clean rooms and aseptic environments with compliant sterility, resistant during the logistical stages and which takes into account cost and environmental constraints.

The aim of the present invention is to overcome the drawbacks of the state of the art by providing equipment for a clean room and aseptic environment whose sterility is maintained during the logistical stages while being less fragile and making it possible to limit the environmental impact and the costs associated with the logistics of protective equipment: decontamination, reconditioning and storage.

To solve these problems, provision is made according to the present invention for protective equipment for a clean room and aseptic environment as mentioned above, characterized in that said protective equipment is packaged in a reusable and sterilizable pouch, made of textile material, presenting an opening provided with closing means.

It appeared in a particularly surprising manner that the protective equipment for clean room and aseptic environment according to the present invention, being packaged in a reusable and sterilizable pouch, made of textile material, provides protective equipment whose direct protection is improved during logistics, storage and opening stages.

It has also appeared in a particularly surprising and advantageous manner that the sterility of protective equipment for a clean room and aseptic environment according to the present invention is improved and maintained during the various logistical stages.

Finally, providing protective equipment for a clean room and aseptic environment according to the present invention, packaged in a reusable and sterilizable pouch, made of textile material, which has an opening provided with closing means makes it possible in a particularly advantageous manner to dispense with packaging, plastic packaging, paper packaging which are single-use, fragile, disposable, consumers of raw materials and which therefore represent a significant cost, on the one hand the cost of the packaging as such, and on the other hand, that -it being fragile to use, it is more subject to an accident resulting in contamination and is therefore linked to a cost of cleaning and decontamination of the clean room.

The pouch according to the present invention forms a cavity with an opening.

Preferably, the pouch comprises at least two walls joined over a majority of their ends to each other and the pouch comprises an opening, preferably a single opening, comprising at least one closure means.

Advantageously, the pouch comprises at least three walls joined over a majority of their ends to each other and the pouch comprises an opening, preferably a single opening comprising at least one closure means.

Preferably, the pocket can be, for example, square in shape, rectangular in shape, hexagonal in shape or even half-moon.

Advantageously, the protective equipment for a clean room and aseptic environment according to the present invention is chosen from the group comprising a garment, for example a suit, an apron, a chasuble, a head covering, for example a cap or a hood, at least one glove, at least one overshoe, one shoe, one clog, one mask, goggles, arm warmers, underwear, boots. Preferably, the pouch of the protective equipment according to the present invention is connected to the inner face or to the outer face by at least one fixing means allowing the securing of the pouch.

Preferably, the pouch of the protective equipment according to the present invention is connected to the interior face of a garment by at least one fastening means allowing the attachment of the pouch to the interior face of said garment.

The pouch of the protective equipment according to the present invention, by being connected to the inner face of a garment and by being integral with this inner face by means of at least one fixing means, makes it possible in a particularly advantageous manner to isolate the pouch from the surrounding environment when the garment is worn by the manipulator.

Indeed, initially the pouch is in contact with the surrounding environment which is contaminated. The pouch, being connected to the inner face of a garment packaged therein, makes it possible, when removing the garment from the pouch and unfolding the garment for dressing the manipulator, to enclose the pouch in the garment, thus isolating from the surrounding environment and consequently limiting the possibility of contamination of the clean room or the aseptic environment.

Advantageously, the at least one means for fixing the protective equipment for clean rooms and aseptic environments according to the present invention is a temporary fixing means, for example a press stud or a series of press studs, a zipper, Velcro means, possibly arranged on a flap tab.

More advantageously, the at least one means of fixing the protective equipment for clean rooms and aseptic environments according to the present invention is a seam or a weld.

Other embodiments of the protective equipment for clean room and aseptic environment according to the present invention are indicated in the appended claims.

The present invention also relates to a garment, and in particular to a suit for a clean room and an aseptic environment.

When a technician has to work in such a sterile environment, he must, before entering the rooms white, put on clothes, and in particular wetsuits, respecting a very specific protocol. Such procedures are very tedious and generally require the manipulator to dress in a way that is completely contrary to what he is used to doing and contrary to the way he would dress instinctively.

The existing suits are therefore sterilized and supplied in waterproof packaging which must on the one hand be easy to open for the manipulator before entering the clean room and, on the other hand, sufficiently resistant to avoid the tearing which could have consequence the contact of the suit with a contaminated environment and therefore the subsequent introduction of contaminants into the clean room, most of the time without the manipulator being able to realize it given the size of the contaminants.

It is therefore easy to understand that on the one hand the personnel, the manipulators and the suits they wear are the main sources of contamination of clean rooms or sanitized environments and on the other hand that contamination is absolutely to be avoided because if such contamination should take place, this would lead to a stoppage of production, the sterilization or even the destruction of the ingredients and materials present and long and costly cleaning steps according to a very specific protocol to once again provide a sterile and aseptic environment.

Thus, the manipulator must then put on the clothes, such as coveralls, without touching the outer face intended to be in contact with the sterile environment and especially, without touching the outer face of the body part, that is to say extending from the pelvis, up the handler's legs to his neck. This therefore entails a whole manipulation during which certain parts of the suit are folded up, where the manipulator stands on a bench, puts on one leg without it touching the ground, then the other leg while taking care not to let go or touch anything. It is easy to understand that this clothing procedure requires gymnastics requiring great dexterity and long years of training and practice, as the risk of contaminating a clean room must be avoided.

• une face extérieure prévue pour être en contact avec le milieu environnant,
• une face intérieure agencée pour être en contact avec un manipulateur,
• une première et une deuxième manche,
• une partie de corps comprenant une partie de tronc et une partie de jambe, lesdites première et deuxième manches étant reliées à la partie de corps, de préférence à la partie de tronc par une extrémité liée, ladite partie de corps comprenant une section de passage de tête,

• a body part comprising a trunk part and a leg part, said first and second sleeves being connected to the body part, preferably to the trunk part by a linked end, said body part comprising a passage section head,
• at least one gripping means in contact with said inner face in the body part, preferably in the trunk part.

Unfortunately, such a garment according to the prior art is packaged in a sterilized envelope or packaging to meet the requirements of clean rooms, in particular in view of the stages of packaging, transport, delivery, opening of packages and therefore clothing for clean rooms. or individual sanitized environment which are all stages during which shocks, cuts, negligence can occur leading to their contamination even if this is not visible to the naked eye but will be detected only when the manipulator will undergo checks or that the products from the clean room will be analyzed. Indeed, the envelopes or packaging sterilized for this type of garment are single-use (and therefore disposable) envelopes or packaging made of plastic.

There is therefore a real need to provide clothing for clean rooms and aseptic environments with improved and maintained sterility during the logistics stages and which takes into account cost and environmental constraints.

The aim of the present invention is to overcome the drawbacks of the state of the art by providing a garment for a clean room and aseptic environment, the direct protection of which is improved, the sterility of which is maintained during the logistical stages and which makes it possible to limit the associated costs. to the garment as such and subsequently associated with decontamination processes.

To solve these problems, there is provided according to the present invention, a garment for a clean room and aseptic environment as indicated above, characterized in that said garment comprises said pocket connected to said inner face of said garment by said fastening means and located on the inside face of said pocket, preferably opposite the opening of said pocket, allowing the fastening of the inside face of said pocket to said inside face of the body part of said garment, preferably to the inside face of the trunk part of said garment.

It appeared in a particularly surprising way that the garment for clean room and aseptic environment according to the present invention, being packaged in a reusable and sterilizable pouch, made of textile material, provides protective equipment whose direct protection is improved during the logistical stages, storage, opening.

It has also appeared in a particularly surprising and advantageous manner that the sterility of the garment for a clean room and an aseptic environment according to the present invention is improved and maintained during the various logistical stages.

Finally, providing a garment for a clean room and aseptic environment according to the present invention, comprising a reusable and sterilizable pouch for its packaging which has an opening provided with closing means makes it possible in a particularly advantageous manner to dispense with packaging, plastic packaging, paper packaging which are for single use, fragile, disposable, consumers of raw materials and which therefore represent a non-negligible cost, on the one hand the cost of the packaging as such, and on the other hand, this being fragile it is more subject to an accident resulting in contamination and is therefore linked to the cost of cleaning and decontamination of the clean room.

In addition, the garment for a clean room and aseptic environment according to the present invention, on the one hand comprising the reusable, sterile pouch which has an opening provided with closing means and, on the other hand comprising at least one gripping means in contact with the inner face in the body part, preferably in the trunk part, of the garment makes it possible, in a particularly advantageous manner, to provide a garment whose sterility is maintained and to provide a garment whose manipulation during dressing is facilitated by means of said at least one gripping means which is directly exposed to the manipulator.

The pouch of the garment for a clean room and aseptic environment according to the present invention, by being connected to the inner face of the garment and by being integral with this inner face by means of at least one fixing means, makes it possible in a particularly advantageous manner to isolate the pocket from the surrounding environment when the garment is worn by the manipulator.

Indeed, initially the pouch is in contact with the surrounding environment which is contaminated. The pouch, being connected to the inner face of the body part of the garment packaged therein, allows when removing the garment from the pouch and unfolding it for dressing the manipulator according to a facilitated protocol, d enclose the pouch in the suit, thus isolating it from the surrounding environment and therefore limiting the possibility of contamination of the clean room.

There figure 1 illustrates protective equipment 1 for a clean room and aseptic environment according to the invention and more particularly a combination 7 for a clean room and aseptic environment comprising an outer face 2 intended to be in contact with the surrounding environment and an inner face 3 arranged to be in contact with a user or manipulator.

The suit 7 comprises a first 9 and a second 10 leg section, each of which comprises a sidewall and two longitudinal edges on either side of the sidewall of the leg section, each of which is also provided with mutual closure means which are arranged to form the substantially tubular leg section when the mutual closure means of each longitudinal edge are engaged together. Further, the engaged mutual closure means of the first leg section faces the engaged mutual closure means of the second leg section, and the mutual closure means each preferably extends from at least one knee area to a crotch area (not shown) and more preferably from a calf or ankle area to a crotch area (not shown).

Although not illustrated in the depicted figures, the first leg section closure means and the second leg section closure means together form a continuous closure of the crotch opening. The closure means are chosen from a zipper, self-gripping means, press-studs, a flap tab or other equivalent or similar means.

The suit 7 also comprises a first sleeve 12, a second sleeve 13 and a body part 14. The first sleeve 12 is connected to the body part 14 by a linked end 12a, the second sleeve 13 is also connected to the body 14 by a bound end 13a. The first leg section 9 and the second leg section 10 are connected to the body part 14 by a bonded end 9a and 10a respectively. Finally, the body part 14 of the suit 7 includes a head passage section 15.

In the embodiment as illustrated in figure 1 , the suit 7 comprises a hood provided with an opening for the eyes above or below which a mask or goggles for example can be placed.

The combination 7 according to the present invention and as illustrated in figure 1 comprises a pocket 4 which is connected to the inner face 3 of the suit 7 by fixing means 8. The fixing means 8 are located on the inner face of the pocket 4 and preferably opposite the opening 5 of the pocket 4. This advantageously allowing the attachment of the inner face of the pocket 4 to the inner face 3 of the body part 14 of the suit 7.

Thus, in the folded and packaged position, the inner face 3 of the suit 7 is connected to the inner face of the pouch 4 so that only the outer face of the pouch 4 is in contact with the surrounding environment as illustrated. to the figure 4 . When the manipulator is going to put on the combination 7, he will, prior to this, open the closing means 6 of the opening 5 of the pocket 4, remove the combination 7 from the pocket 4 using the gripping means 16 After carrying out this step, when the combination 7 is taken out of the pocket 4, a reversal, an inversion of the faces of the pocket 4 will take place.

In a particularly advantageous manner, on the one hand the outer face of the cover 4, which was exposed to the surrounding environment, will become the inner face of the cover 4. On the other hand the cover 4 by being connected to the inner face 3 of the combination 7 will therefore be found inside the combination 7 when the latter is worn by the manipulator.

Consequently, the pouch 4 of the protective equipment 1 and more particularly of the suit 7 according to the present invention makes it possible to produce a double insulation from possible contaminants. The first insulation being carried out by the reversal of the outer face of the pocket 4 which is found inside the pocket 4, the contaminants are therefore contained in the pocket 4. The second insulation being carried out by the confinement of the pocket 4 inside the suit 7.

In the embodiment of the figure 1 , the first sleeve 12 comprises self-tightening means 17 at a free end, opposite the bound end 12a, in the form of a wrist made of elastic fabric. The second sleeve 13 comprises at the free end, opposite the linked end 13a, also self-tightening means 17, in the form wristband in elastic fabric. The elastic fabric cuffs as shown in the figure 1 can also be replaced by a pressure tab, or self-gripping means, or even other conventional tightening means.

Furthermore, according to the embodiment of the protective equipment 1 and more particularly of the suit 7 of the figure 1 , the combination 7 has, in the deployed position in which the outer face 2 of the combination 7 is in contact with the surrounding environment and the inner face 3 is arranged to be in contact with a manipulator. The first inside face of the cover 4 is against the inside face 3 of the combination and the second inside face of the cover 4 is arranged to be in contact with or oriented towards a manipulator. The closing means 6 of the opening 5 of the pouch 4 are preferably in the open position. It is obviously possible for the closure means 6 to be in the closed position, in particular to isolate the outer faces of the pocket 4, inside the pocket 4 when the suit 7 is in the deployed position.

The combination 7 according to the present invention comprises at least one gripping means 16 in contact with the inner face 3 in the body part 14, preferably located laterally. In the variant illustrated in figure 2a , the combination 7 according to the invention comprises two gripping means 16 in contact with the inner face 3 in the body part 14, located laterally, on either side of the opening 11. In the other variant illustrated in figure 2b , the combination 7 according to the invention comprises a gripping means 16 in contact with the inner face 3 in the body part 14.

THE figures 2A and 2B illustrate two embodiments of the combination 7 according to the present invention in the partially folded position. The inner face 3 of the first leg section 9 and of the second leg section 10 are exposed outward to the surrounding environment. The exterior face 2 of the first leg section 9 and of the second leg section 10 are exposed towards the exterior face 2 of the body part 14. This particular arrangement according to the present invention forms an opening 19 itself arranged to give access inside the body part 14 and preferably inside the trunk part of the suit 7.

In this way, the at least one gripping means 16 is exposed towards the manipulator.

In the embodiment of the figure 2A , the combination 7 according to the invention comprises two gripping means 16 exposed towards the manipulator.

In the embodiment of the figure 2B , the combination 7 according to the invention comprises a gripping means 16 exposed towards the manipulator.

In yet another embodiment not illustrated, the gripping means 16 of the combination 7 according to the present invention can be parts of the material of the inner face 3 of the combination 7 and therefore exposed towards the manipulator. In addition, the different parts of material of the inner face 3 of the suit 7 or of the protective equipment 1 for a clean room or aseptic environment can be of different color, texture or pattern to facilitate their identification by the manipulator as being the gripping means 16.

Indeed, the gripping means 16 according to the figures 2A and 2B are present on the inside face 3 of the suit 7 and the fact of partially turning the leg sections over the body section makes it possible to expose them to the outside and therefore to the manipulator.

It is therefore easy to understand from the combination 7 according to the present invention that the folding process steps must be respected in order to maintain the sterility of the combination 7, this in particular following the removal of the combination 7 by the manipulator and its cleaning, decontamination and subsequent reconditioning.

Particularly advantageously, the combination 7 according to the present invention comprising the pouch 4 makes it possible to dispense with single packaging and to be cleaned and repackaged directly in its protective pouch 4, itself cleanable, sterilizable and reusable.

During this folding step, the handler folds down the exterior face of a first 9 and a second 10 leg section by passing an open crotch section over an exterior face of a body part 14 while maintaining the at least one gripping means 16 exposed.

The second step of the folding process is that illustrated in picture 3 . In this step, the first leg section 9 is folded longitudinally on itself and the second leg section 10 is also folded longitudinally on itself while leaving the two gripping means (16) exposed towards the manipulator. In addition, the last folding step of the combination according to the invention is illustrated by arrows on the picture 3 . Indeed, the combination 7 according to the invention thus folded will then be folded transversely on itself in two or three parts or even more if necessary, depending on the size of the combination. The suit 7 thus folded is then packaged in the pouch 4 accessible in the body part 14 of the suit 7. Once folded and packaged, the pouch 4 containing the suit 7 as illustrated in figure 4 can for example be sterilized, for example, in an autoclave.

When a user intends to put on a suit 7 according to the invention, he opens the closing means 6 of the opening 5 of the pouch 4, he grasps the first gripping means 16 with a first hand and the second gripping means 17 by the second hand and removes the combination 7.

In this way, he obtains a combination 7 in the partially folded position as illustrated in figure 2A . The suit 7 is positioned so that the body part 14 is accessible via the crotch opening 19 of the suit, through the waist section. The manipulator then puts on, after having released the second gripping means 16, his second arm in a second sleeve 13 and, after having let go of the first gripping means 16, he puts on the first arm in the first sleeve 12. He then puts his head in an opening in the body portion 14 through the waist section and then into the head passage section 15 before terminating in the hood.

He then turns the leg sections 9, 10 over so that the outer face of the first leg section 9 and the second leg section 10 are exposed to the outside and so that the inner face of the first leg section 9 and the second leg section 10 are exposed towards the legs of the manipulator. Then, the manipulator positions his foot in the foot passage section which comprises the pre-engaged zipper and closes said opening 19 to completely isolate his body from the external environment.

There figure 5 illustrates clogs as protective equipment for a clean room or aseptic environment according to the present invention. The clogs as illustrated comprise a series of press studs 8 of which a first part of the male button is located on the clogs and a second part of the female button is located on the cover 4, the reverse is obviously possible. Thus the clogs can be fixed integrally to the pocket 4, and positioned inside the pocket 4 so that during the removal, the clogs will be removed and the pocket 4 will be turned over on itself as explained above for isolate contaminants inside the pouch 4.

There figure 6 illustrates protective boots as protective equipment for clean room and aseptic environment according to the present invention. The protective boots as illustrated comprise a series of press studs 8 of which a first part of the male button is located on the boots and a second part of the female button is located on the pocket 4, the reverse is obviously possible. Thus the protective boots can be fixed integrally to the pocket 4, and positioned inside the pocket 4 so that during removal, the protective boots will be removed and the pocket 4 will be turned over on itself as explained previously to isolate contaminants inside pocket 4.

There figure 7 illustrates gloves, overshoes, a charlotte and a hood as protective equipment for a clean room and aseptic environment according to the present invention. The protective equipment as illustrated can comprise a means of attachment 8 to the pouch 4, such as a press stud. Thus they can be fixed integrally to the pocket 4, and positioned inside the pocket 4 so that during removal, the protective equipment will be removed and the pocket 4 will be turned over on itself as explained above to isolate contaminants inside the pouch 4.

There figure 8 illustrates pants according to the present invention comprising a first 9 leg section and a second 10 leg section. Pants as pictured include one side interior 3 and an exterior face 2, and also comprises the pouch 4 according to the present invention.

Thus the manipulator can put on the pants and the pocket 4 as presented previously, being located inside the pants makes it possible to isolate the contaminants, a first time in the pocket 4 and a second time in the interior part of the pants which is isolated from the surrounding environment.

It is understood that the present invention is in no way limited to the embodiments described above and that many modifications can be made thereto without departing from the scope of the appended claims.
