Biological sample collection and transport device

Abstract From the Canadian patent

A microbiological culture collection and transport device maintains viable organisms for periods of time longer than possible with existing sampling devices. It also allows recovery of detectable antigen at levels not achievable with conventional swabs. The new device has a sterile swabbing tip made with a non-toxic polyurethane foam having open cells at its exposed surface. It does not require a transport medium and can be used dry. The device may further include a sample inoculator to distribute organisms collected onto a solid or semi solid medium. Methods for collecting and transporting microbiological specimens and for recovering detectable antigen are also described.
