Definitions
- the present invention relates to a process for passing through an airlock between an external volume and an aseptic enclosure, comprising - donning by an operator of a waterproof and impermeable suit of the diving suit type, supplied with breathable air, penetration of the operator in the airlock by opening a first access allowing passage between the external volume and the airlock, in the closed position of a second access allowing a passage between the airlock and the aseptic enclosure,
- aseptic chambers known as pharmaceutical grade, in which pharmaceutical products are manufactured and / or handled, must meet criteria of purity which are moreover regulated in known standards (see the regulation of drugs in the European Union, Vol. 4, Good Manufacturing Practices, Medicines for Human Use and Veterinary Medicines, 1999 ed. 21 Code of Federal Regulations, Parts 210 and 211, US Food and Drug Administration, 9/29/1978).
- the major problem posed by these enclosures is that, when an operator enters it, the latter does not cause contaminating agents or even simple dust inside the enclosure, whether on his clothes or by the supply of outside air which he brings in when entering or breathing. It is of course also important that the operator, if necessary, is not likely to be intoxicated by the pharmaceutical substances which he handles in the enclosure and that he does not carry with him toxic particles.
- the operator puts on overalls made of synthetic fabric, composed of 3 to 4 pieces, which is sterilized or disinfected beforehand and which allows the operator to breathe ambient air at through a surgical mask or in some cases using a facial suit which sucks in ambient air and expels the expired air through a filter.
- the closed airlock is supplied with sterile air and the airlock is regulated in temperature, pressure and humidity in a manner corresponding to what is in the aseptic enclosure. Then, the operator enters the enclosure.
- This operating mode has several major drawbacks.
- the operator himself contaminates the outside of the sterilized overalls, not only while putting it on, but also while wearing it because of the lack of waterproofness in his clothing. It has been found that a large proportion of the contamination present in conventional aseptic chambers is in fact brought in by the operator himself, as a result.
- the operator is also obliged, when leaving the enclosure, to get rid of the overalls and then put on a new one if he wants to re-enter the enclosure. Hence an enormous cost of maintenance and sterilization or disinfection of overalls.
- a process for passing through an airlock which notably comprises sterilization of the overalls inside the airlock (see for example US-A-4,304,224).
- This process has the disadvantage that sterilization is carried out by the creation of a gaseous atmosphere in which the sterilizing agent is atomized and is in a suspension as in a mist. It is difficult to conceive under these conditions sterilization, or even effective disinfection in the pharmaceutical sense and reproducible of the overalls in all its parts, sometimes hidden, such as the underside of the arms, feet, crotch, etc.
- the elimination of the disinfecting agent is done by a complicated process of washing the air in the airlock and heating the washed air, reintroduced into the airlock.
- a multiple airlock is finally provided and a process for passing between an enclosure containing contaminating materials, toxic or irradiating substances or even biologically dangerous media and the external environment.
- the major problem therefore consists in leaving these enclosures without any problem for the environment and the constraints are therefore completely different from those of entering a pharmaceutical grade enclosure.
- the object of the present invention is to develop a process for passing through an airlock between an external volume and an aseptic enclosure as well as an airlock which make it possible to comply with the pharmaceutical quality standards mentioned above inside the aseptic enclosure, by solving the problems mentioned above.
- the process comprises disposal out of the airlock of the disinfectant liquid that drips from the overalls and from the interior walls of the airlock during and after disinfection, and, after disinfection, a blowing in the airlock, on the overalls, of turbulent streams of sterile air at room temperature , with the evacuation of the air loaded with disinfectant and possibly humidity from the airlock, until drying of the overalls and the internal walls of the airlock.
- Disinfection with jets of sterile, sprayed disinfectant liquid provides excellent results on all parts of the overalls.
- the method provides for blowing sterile air preferably at room temperature and at a flow speed greater than 15 m / s, advantageously 20 m / s, over the overalls which in this way dries quickly at the same time as the interior walls of the airlock, while a replacement, preferably as complete as possible of the air loaded with sterilizing agent and possibly with humidity by fresh sterile air takes place.
- the pressure inside the enclosure is greater than that of the airlock which, in turn, is greater than that of the external environment. The airlock is therefore overpressure relative to the latter.
- This pressure cascade complies with pharmaceutical standards and makes it possible to protect the atmosphere of the aseptic enclosure.
- the air which, despite the difference in pressure between the enclosure and the airlock, enters with it the aseptic enclosure is at a temperature and a relative humidity rate identical to those present therein.
- any liquid suitable for this purpose can be used, and in particular a mixture of bleach and soap or products placed on the market under the name of Dettol or HAC for example.
- the method comprises a continuous formation, in the airlock, of a laminar flow of sterile air oriented from top to bottom.
- a laminar flow which constantly directs downwards any particle or droplet suspended in the air.
- this air can be recirculated at least partially.
- it further comprises, in the closed airlock, before disinfection, a prior blowing of turbulent streams of sterile air on the overalls, which detach particles therefrom of the type dust. This pre-blowing thus allows a kind of dry cleaning which dust the overalls. The dust is then immediately dragged down and out of the airlock by the laminar flow of the air conditioning air.
- the invention also relates to an airlock between an external volume and an aseptic enclosure, comprising walls delimiting the airlock, in which are arranged a first access door allowing in the open position a passage between the external volume and the airlock and a second access door allowing in the open position a passage between the airlock and the aseptic enclosure, means for supplying breathable air to a waterproof and impermeable suit of the diving suit type worn by an operator present in the airlock, and means for introducing disinfectant liquid into the airlock.
- the aseptic enclosure is of pharmaceutical quality and the disinfectant liquid is sterile
- the means for introducing sterile disinfectant liquid comprise projection nozzles which are in leaktight communication with a source of disinfectant liquid under pressure and are oriented in the airlock so as to spray this sterile disinfectant liquid over the whole of the overalls
- the airlock also comprises means for removing the disinfectant liquid which comprise at least one opening in a lower part of the airlock which collects the disinfectant liquid which drips during the projection, blowing means capable of introducing into the airlock turbulent streams of sterile air at room temperature towards the overalls and means of evacuation from the airlock of the supply air loaded with disinfectant and possibly humidity.
- FIG. 1 represents a schematic sectional view through an airlock according to the invention, along the line l-l of FIG. 3.
- FIG. 2 represents a sectional view along the line II-II of FIG. 1.
- FIG. 3 represents a sectional view along line III-III of FIG. 2.
- FIG. 4 represents in a perspective view the circuit for supplying disinfectant liquid.
- identical or analogous elements are designated by the same references.
- the airlock 1 illustrated in Figures 1 to 3 comprises four side walls 2 to 5, a ceiling wall 6 and a floor wall 7.
- Two access doors are arranged in the airlock, the first door 8 allows passage between a external volume 9 and the airlock 1 and the second door 10 allows passage between the airlock 1 and the interior of the pharmaceutical grade aseptic enclosure 11.
- a false ceiling 12 which allows the formation of an upper compartment 13 in which is mounted a fan 14 which operates continuously and blows down a current d 'air.
- a HEPA type filter 15 which allows the passage of the air blown by the fan 14 in a perfectly sterile and dust-free manner, the air flowing in a laminar flow at the outlet of the filtered.
- a grid 16 which allows the laminar air flow to flow inside the airlock 1 from top to bottom.
- a raised floor 17 in the form of a grid which allows the formation of a lower compartment 18 in which the air coming from the airlock can escape.
- the air collected at the bottom of the airlock in the lower compartment 18 can, in the illustrated embodiment, be evacuated in an outlet duct 19, when the recirculation valve 20 is open.
- the air is then passed into a standard conditioning unit 21.
- This unit includes a condenser 22 which makes it possible to eliminate from the circuit the excess moisture present in the circulating air, by means of the condensed liquid conduit 71.
- the unit 21 further comprises, following the condenser 22, a heating device 23 which heats the air to the ambient temperature required in the airlock. This air regulated in temperature and humidity is then reintroduced into the upper compartment 13 of the airlock by the supply conduit 24.
- the airlock has false side walls 25 and 26 which form side compartments each subdivided into 2 sections, a lower section 27 and 28 respectively and an upper section 29 and respectively 30, by partitions 31 and 32.
- the lower sections 27 and 28 are in communication with the lower compartment 18 via the grid 17.
- a fan 33 and respectively 34 whose outlet 35 and respectively 36 opens into the corresponding upper section (see FIG. 3).
- each upper section 29 and respectively 30 two filters 37, 38 and respectively 39, 40 of the HEPA type are mounted, which open into vertical corner compartments 41, 42 and respectively 43, 44 and which filter the air absolutely sterile and dust-free.
- the corner compartments are in communication with air supply sleeves 45, 46, 47 and respectively 48 arranged vertically at the four corners of the internal volume of the airlock, that is to say around the operator when the latter is inside the airlock. Ventilation openings 49 are arranged along each of the sleeves.
- an air inlet duct 51 provided with an inlet valve 52.
- This circuit includes a reservoir 53 for any suitable disinfectant liquid.
- This reservoir can be pressurized by a sterile compressed air source (not shown) which is in communication with the reservoir 53 by the conduit 54.
- a liquid outlet conduit 55 plunges into the bottom of the reservoir 53 and brings the pressurized liquid to a sterilizing filter 56.
- the sterile filtered disinfectant liquid is transferred to the lower compartment 18 of the airlock by a transfer conduit 57 where it opens into a distributor 58.
- the distributor 58 supplies sterile disinfectant liquid under pressure from the supply conduits 59 to 62 which are housed, in the illustrated embodiment, inside the vertical sleeves 45 to 48.
- the distributor can also supply two supply conduits 63 and 64 which are arranged below the grid 17.
- conduits feed 59 to 64 are provided over their entire length with projection nozzles 65 directed towards the interior of the airlock.
- the nozzles 65 of the conduits 59 to 62 pass through orifices provided for this purpose in the sleeves 45 to 48.
- compartment 18 there are also advantageously provided two inclined sheets 66 and 67 which promote a flow of the disinfectant liquid, which drips down, during disinfection, to a conduit for discharging disinfectant liquid 68.
- the liquid is sucked by a pump 69, for example a peristaltic pump, to a waste liquid tank 70.
- Overalls means a protective suit, made of preferably in one piece and covering the whole body.
- This spacesuit type garment is waterproof and waterproof in both directions.
- the operator is supplied with breathing air from a source of air not shown, and this in a known manner and not explained in detail, via a flexible duct 74.
- the air exhaled by the operator can be evacuated by a sterilizing filter cartridge 75, for example of type P3 according to the above-mentioned standards (European Norm EN 12941/2), which is easily replaceable and located at the bottom of the overalls.
- Suspension elements 73 can also be provided in the airlock to help the operator keep the arms raised during disinfection and drying, and also to guarantee the correct positioning of the operator and the reproducibility of the cycle.
- the operation of the airlock illustrated is as follows.
- valves 50 and 52 are closed and the pump 69, the fans 33 and 34 and the compressed air source of the tank 53 are out of service.
- the recirculation valve 20 is in the open position and the fan 14 is in operation. The latter remains in operation for the entire duration of use of the airlock 1.
- the conditioning unit regulates the air entering the upper compartment 13 at a temperature of 20 ° C ⁇ 2 and at a relative humidity level of 50% + 10.
- the fan 14 allows an air flow speed 0.45 m / s.
- the HEPA 15 filter can for example have an area of 915mm x 915mm.
- the flow rate is set for example at 1350 n Vh.
- the air thus flows from top to bottom in a linear fashion in an interior space of the airlock whose volume is about 3.5 m 3 .
- the overpressure thus imposed is approximately 30 Pa. This airlock regulation allows the air contained in the airlock to be renewed from 200 to 600 times per hour.
- a diving suit of the diving suit type for example in a pharmaceutical classification room 10,000, this jumpsuit does not necessarily have to be sterile. he then enters the airlock, which can for example meet the standards of a local pharmaceutical classification 1,000.
- a control panel 76 is provided inside the airlock.
- the buttons in the table each correspond to a separate command to start or stop an item of equipment or to an operator movement. It is not possible to proceed to the next order if the previous one has not been completely completed.
- the operator After entering the airlock, in the closed position of the door 10, the operator closes the door 8 and places himself in the appropriate position for the feet and hands.
- electrical sensors are provided on the ground for the feet and, for the hands, the operator must suspend them from the suspension elements 73.
- the recirculation valve 20 can then be closed, while the valves 50 and 51 are open and the fans 33 and 34 are put into service.
- the closure of the valve 20 is however not compulsory.
- Turbulent air is then blown for approximately 20 sec. preferably at a speed greater than 20 m per second in the direction of the overalls to detach the dust particles which adhere to it. This sterile air comes, in the example illustrated, from 24 air ventilation outlets 49.
- valves 50 and 51 are again closed.
- the valve 20, if it has been closed, is returned to the open position and the laminar air flow continues in the airlock, which makes it possible to direct the dust detached from the overalls towards the bottom of the airlock.
- the compressed air source of the disinfectant liquid circuit is then started as well as the peristaltic pump 69.
- the projection nozzles 65 can advantageously be supplied with sterile disinfectant liquid independently of one another. We can for example start with the nozzles 65 located below the grid 17. During this projection, the operator must successively lift feet to get complete disinfection. Then the 20 projection nozzles 65 placed in the corners of the airlock are put into service and disinfect all of the overalls under the jets of sprayed disinfectant liquid. The residual disinfectant which drips during this operation is collected from below towards the tank 70.
- the disinfectant liquid circuit is then put out of service, while the air conditioning with laminar air flow is maintained.
- the fans 33 and 34 are returned to service and the valves 50 and 51 are returned to the open position.
- a drying step then takes place during which a large part or even all of the air present in the airlock is evacuated by the conduit 77 and the valve 50, this air being replaced by sterile conditioned air supplied by the conduit 24.
- the powerful jets of sterile air dry the overalls and the internal walls of the airlock 1.
- the drying is stopped when the required humidity level is reached in the airlock, and for example after a period of approximately 5 minutes.
- the pressure inside the airlock was maintained during the whole process at around 30 Pa.
- the pressure parameters of the airlock can be modified according to the pressure prevailing in the adjacent aseptic enclosure, so as to always be 5 Pa lower than this.
- the operator can then enter the aseptic enclosure 11, that is to say for example a pharmaceutical classification room 100 B / A, by opening the door 10, while the door 8 remains closed.
- the passage in the airlock lasted approximately 15 minutes, including clothing.
- Example 1 Disinfectant used: Dettol 5% in city H 2 O Dusting phase: 20 seconds Disinfection phase: Spraying: 40 seconds
- Example 2 Disinfectant used: Dettol 5% in city H 2 O Dusting phase: 20 seconds Disinfection phase: Spraying: 100 seconds
- Example 3 Disinfectant used: Dettol 5% in city H 2 O Dusting phase: 20 seconds Disinfection phase: Spraying: 20 seconds Total contact time: 5 minutes Quantity of disinfectant used: 3.25 liters Drying phase: 5 minutes Verification of drying by visual examination: OK
