Abstract

A specimen gathering method and apparatus having a piston operated ejectable scoop member. Preferably, the specimen gathering device inserts into a container and releasably seals the container. The apparatus is useful for gathering and transporting stool and other biological specimens.

Claims

1. A specimen gathering device comprising:

an elongate housing having a bore therethrough, a first end, a second end, and a spring compression member disposed within said bore;

a moveable piston means disposed within said bore having a proximal end disposed within said bore, and a spring engagement member located within said bore, said spring compression member being located between said proximal end and said spring engagement member;

a push rod having a handle end extending exterior to said first end of said housing and a proximal end disposed within said bore and in contact with said piston means spring engagement member;

a spring means in spring engagement with said spring management member and said spring compresion member urging said piston means toward said first end;

an ejectable scoop member having a scoop end and an insert end, said insert end removably mounted within said second end so that said ejectable scoop member is removed from said second end when said piston is moved toward said second end and said proximal end forces said ejectable scoop member out of said second end; and

a sealing member, sized to sealingly engage a pre-selected container having an open end, said sealing member fixed to the exterior of said elongate housing and oriented to seal said second end within said container.

2. The specimen gathering device of claim 1, including a container sized to fit said sealing member.

3. The specimen gathering device of claim 1, wherein the scoop end of said scoop member is spoon-shaped.

4. The specimen gathering device of claim 1, wherein said elongate housing, said moveable piston means, said spring compression member, and said ejectable scoop member are molded from plastics for disposable use.

5. The specimen gathering device of claim 1, wherein said sealing member is an annular member.

6. The specimen gathering device of claim 5, wherein said sealing member includes a shoulder to enhance the seal between it and said container.

7. The specimen gathering device of claim 1, wherein said elongate housing comprises two interlocking pieces.

8. The specimen gathering device of claim 7, wherein said moveable piston means spring engagement member is integrally connected to said push rod proximal end within said elongate housing.

9. The specimen gathering device of claim 8, wherein said spring compression member is located at a junction between the two interlocking pieces in said elongate housing.

10. A method for the sanitary collection of stool or other biological samples comprising:

(a) collecting a portion of the sample in an ejectable scoop member held in a scoop member housing;

(b) inserting the sample containing scoop member into a cylindrical container having an open end and a closed end;

(c) dislodging the sample from the scoop member into the container; and

(d) disengaging the ejectable scoop member from said scoop member housing.

11. The method of claim 10, wherein said ejectable scoop is disengaged from said scoop member housing after removal from said cylindrical container.

12. The method of claim 11, including the step of sealing said container for transport.

13. The method of claim 10, wherein said ejectable scoop member is disengaged from said scoop member housing within said cylindrical container.

14. The method of claim 13, including the step of sealing said open end of said cylindrical container with a sealing member mounted on the external surface of said scoop member housing.

15. The method of claim 13, including the step of transporting the sealed container.
