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 squeeze 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.
