Abstract

The invention generally relates to an easy-to-use device for the safe and secure transport of samples and specimens from the field to the laboratory. The invention is particularly suited for use with forensic samples, as it facilitates the drying of the sample, while protecting the sample from the environment and protecting the environment from contamination with the sample.

Claims

1. A method for collecting evidence samples using a sample collection means having a shaft and a sampling head mounted on a proximal end of said shaft and a perforated shield slidingly mounted on a distal end of said shaft, comprising the steps of:

a) exposing said sampling head to a sample, thereby providing a collected sample; and

b) drawing said sampling head containing said collected sample into said perforated shield by pulling said distal end of said shaft away from said perforated shield, thereby providing an evidence sample.

2. The method of claim 1, wherein said shield further comprises a collar.

3. The method of claim 1, wherein said shield further comprises a guiding hub.

4. The method of claim 1, further comprising the step of allowing said collected sample to dry.

5. The method of claim 1, further comprising the step of placing said evidence sample within a transport apparatus.

6. The method of claim 5, further comprising the step of transporting said evidence sample.

7. A method for collecting evidence samples using a sample collection means having a shaft and a sampling head mounted on a proximal end of said shaft and a perforated shield having a guiding hub wherein said perforated shield is slidingly mounted on a distal end of said shaft, comprising the steps of:

a) exposing said sampling head to a sample to provide a collected sample;

and

b) drawing said sampling head containing said collected sample through said guiding hub of said perforated shield by pulling said distal end of said shaft away from said perforated shield, thereby providing an evidence sample.

8. The method of claim 7, further comprising the step of allowing said collected sample to dry.

9. The method of claim 7, further comprising the step of placing said evidence sample within a transport apparatus.

10. The method of claim 7, further comprising the step of transporting said evidence sample.
