Abstract
Abstract A swab transport apparatus for storing and transporting to a laboratory a swab containing a sample or specimen such as a micro organism sample. The uncontaminated swab is pre-packaged within a sterile swab storage chamber of the apparatus from which it can conveniently be removed for taking a sample. Disposed proximate the swab storage chamber and in communication therewith, is a squeeze bulb to which a suitable transport medium can be added either at time of manufacture of the device, or shortly prior to use. Following addition of the transport medium the squeeze bulb and the return of the contaminated swab to the apparatus, the squeeze bulb is squeezed to cause the transport medium to flow, preferably via a circuitous path, into the swab storage chamber. The apparatus can then be forwarded to the laboratory for testing with the swab safely immersed within the appropriate transport medium. In an alternate form of the apparatus, a second squeeze bulb is provided. This second squeeze bulb is in communication with the swab storage chamber and enables withdrawal therefrom of a sample of the transport medium which surrounds the contaminated swab. Where appropriate, the second squeeze bulb can be severed from the apparatus and forwarded to the laboratory for preliminary testing.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
193 words
A swab transport apparatus for containing and transporting a swab of the character having an elongated stem and a bibulous swab material carried proximate one end of the stem, said apparatus comprising: (a) an elongated plastic body having resiliently deformable side walls and first and second ends, said body being open at said first end and including: (i) a first elongated chamber communicating with said first open end for receiving at least a portion of the swab; (ii) a chamber axially aligned with a central axis of said first elongated chamber and having resiliently, deformable side walls for containing fluid therewithin, said second chamber being longitudinally spaced from said first chamber; (iii) a reduced diameter portion disposed intermediate said first and second chambers, said reduced diameter portion being in communication with both said first and second chambers; and (iv) a tubular segment disposed proximate said second end of said body, said segment having fluid passageway means extending therethrough for interconnecting said second chamber with atmosphere; and (b) a removable first cover means for sealably closing said open first end of said body said cover being removable for insertion and removal of the swab.
Claim 2
Dependent Claim
193 words
A swab transport apparatus for containing and transporting a swab of the character having an elongated stem and a bibulous swab material carried proximate one end of the stem, said apparatus comprising: (a) an elongated plastic body having resiliently deformable side walls and first and second ends, said body being open at said first end and including: (i) a first elongated chamber communicating with said first open end for receiving at least a portion of the swab; (ii) a chamber axially aligned with a central axis of said first elongated chamber and having resiliently, deformable side walls for containing fluid therewithin, said second chamber being longitudinally spaced from said first chamber; (iii) a reduced diameter portion disposed intermediate said first and second chambers, said reduced diameter portion being in communication with both said first and second chambers; and (iv) a tubular segment disposed proximate said second end of said body, said segment having fluid passageway means extending therethrough for interconnecting said second chamber with atmosphere; and (b) a removable first cover means for sealably closing said open first end of said body said cover being removable for insertion and removal of the swab.
Claim 3
Dependent Claim
30 words
A swab transport apparatus as defined in claim 1 in which said body further includes a generally frustoconical shaped transition portion disposed intermediate said first chamber and said diameter portion.
Claim 4
Dependent Claim
