Abstract
A device for collecting particles and microorganisms present in ambient air, the device comprising means for sucking air into a small volume enclosure in which the particles and microorganisms are separated from the sucked-in air by centrifuging, the device being portable, self-contained, and capable of being handled in one hand only, e.g. by means of a handle associated with the air suction means.
Claims17
A device for collecting and separating particles and microorganisms present in ambient air, the device comprising means for sucking air into a centrifugal enclosure having means for retaining particles or microorganisms and means for exhausting of the sucked-in air, wherein the enclosure is removably mounted on the device and forms a receptacle for transporting collected particles and microorganisms, and wherein the enclosure comprises a small volume cylindrical chamber having volume less than about 200 cm3, in which the particles and microorganisms conveyed by the sucked-in air are set into rotation about the axis of the enclosure and are separated from the sucked-in air by centrifuging against the inside wall of the enclosure, said enclosure co-operating with the air suction means to constitute a self-contained, portable assembly that can be manipulated using only one hand.
A device for collecting and separating particles and microorganisms present in ambient air, the device comprising means for sucking air into a centrifugal enclosure having means for retaining particles or microorganisms and means for exhausting of the sucked-in air, wherein the enclosure is removably mounted on the device and forms a receptacle for transporting collected particles and microorganisms, wherein the enclosure includes automatic closure means for closing its top end, which means are open while the enclosure is mounted on the device and are closed while the enclosure is separate from the device.
A device for collecting and separating particles and microorganisms present in ambient air, the device comprising means for sucking air into a centrifugal enclosure having means for retaining particles or microorganisms and means for exhausting of the sucked-in air, wherein the enclosure is removably mounted on the device and forms a receptacle for transporting collected particles and microorganisms, wherein the enclosure is mounted on the device by resilient snap-fastening or by turning through one-fourth of a turn.
A device for collecting and separating particles and microorganisms present in ambient air, the device comprising means for sucking air into a centrifugal enclosure having means for retaining particles or microorganisms and means for exhausting of the sucked-in air, wherein the enclosure is removably mounted on the device and forms a receptacle for transporting collected particles and microorganisms, wherein the enclosure is mounted on a main top wall including an axial air outlet and a tangential air inlet.
A device for collecting and separating particles and microorganisms present in ambient air, the device comprising means for sucking air into a centrifugal enclosure having means for retaining particles or microorganisms and means for exhausting of the sucked-in air, wherein the enclosure is removably mounted on the device and forms a receptacle for transporting collected particles and microorganisms, including means for injecting liquid into the top portion of said enclosure.
A device for collecting and separating particles and microorganisms present in ambient air, the device comprising means for sucking air into a centrifugal enclosure having means for retaining particles or microorganisms and means for exhausting of the sucked-in air, wherein the enclosure is removably mounted on the device and forms a receptacle for transporting collected particles and microorganisms, including a handle containing a tank of liquid, means for putting the liquid in the tank under pressure, and means for connecting the tank to means for injecting the liquid into the above-mentioned enclosure.
A device for collecting and separating particles and microorganisms present in ambient air, the device comprising means for sucking air into a centrifugal enclosure having means for retaining particles or microorganisms and means for exhausting of the sucked-in air, wherein the enclosure is removably mounted on the device and forms a receptacle for transporting collected particles and microorganisms, wherein the removable enclosure is for single use, or is made of a material suitable for putting in an autoclave.
A device for collecting and separating particles and microorganisms present in ambient air, the device comprising means for sucking air into a centrifugal enclosure having means for retaining particles or microorganisms and means for exhausting of the sucked-in air, wherein the enclosure is removably mounted on the device and forms a receptacle for transporting collected particles and microorganisms, wherein the means for exhausting air from said enclosure include a filter for capturing particles and microorganisms of dimensions smaller than about 1 μm.
A self-contained and portable kit for separating and collecting particles and microorganisms present in ambient air, the kit comprising a device for collecting and separating particles and microorganisms present in ambient air, the device comprising means for sucking air into a centrifugal enclosure having means for retaining particles or microorganisms and means for exhausting of the sucked-in air, wherein the enclosure is removably mounted on the device and forms a receptacle for transporting collected particles and microorganisms, together with a bag of accessories comprising removable spare enclosures;
- at least one tank of injection liquid;
- and at least one rechargeable battery.
