Abstract

The invention relates to a device for sampling tissue from an animal, comprising sampling means provided with at least one cutting element (35) for cutting and collecting a sample of tissue from the animal, and means (31) for storing the sample, into which the cutting element is inserted once the sample has been collected. According to the invention, the storage means (31) have at least two openings, a first opening (32) for receiving the cutting element and the sample, and a second opening (33) cooperating with the detachable closing means (34).

Claims

1. An animal tissue sampling device comprising:

a sampling means having at least one cutting element for collecting an animal tissue sample from an animal, and

a storage means having a first end and a second end and defining an internal volume for storing a sample of animal tissue, wherein the at least one cutting element of the sampling means is dimensioned to be inserted in the storage means, the storage means having at least two openings;

a first opening located at the first end of the storage means and dimensioned to enable said cutting element of the sampling means and said sample, to be received in the storage means, and wherein said cutting element seals said first opening after the insertion of the cutting element in the first opening; and

a second opening located at the second end of the storage means, distinct from said first opening, and having a removable closure means that enables access to the internal volume of the storage means.

2. The device according to claim 1, wherein said storage means includes at least one wall defining two compartments within the storage means, a first compartment being defined between the first opening and the wall and a second compartment being defined between the wall and the second opening.

3. The device according to claim 2, wherein said at least one wall is permeable.

4. The device according to claim 2, wherein said at least one wall includes an element belonging to the group consisting of:

a membrane,

a grid, and

a partition perforated with at least one opening.

5. The device according to claim 1, wherein the storage means contains at least one drying agent within the storage means'"'"' internal volume.

6. The device according to claim 1, wherein the closure means contains at least one drying agent.

7. The device according to claim 1, wherein the storage means has a cylindrical shape.

8. The device according to claim 1, wherein the closure means are reversibly securable to said storage means.

9. The device according to claim 1, wherein the closure means includes a hermetic seal reversibly secured to the storage means by a securing means selected from a group consisting of fitting, clipping, and screwing;

said storage means comprising first securing means; and

said closure means comprising second securing means complementary to said first securing means.

10. The device according to claim 1, wherein the sampling means further comprises an anti-return means dimensioned such that the sample may pass through the anti-return means, and disposed such that the sample is separated from the sampling means after the sample passed through the anti-return means.

11. The device according to claim 1, wherein said anti-return means are formed by a washer perforated at the washer'"'"'s center, and having a plurality of flexible strips extending radially inward toward said center.

12. The device according to claim 1, wherein said storage means contains at least one of either a preservative or reactive liquid.

13. The device according to claim 12, wherein said storage means includes a sealing lid, isolating said liquid and configured to be perforated when a sample is inserted into said storage means.

15. The device according to claim 1, wherein the sampling means further comprises a push element, wherein the push element is disposed in moving relation to the cutting element such that the movement of the push element urges the sample from the cutting element and into the storage means, and wherein the first opening of the storage means is dimensioned to receive at least a portion of the push element, and whereby the push element seals the sample means once received thereby.

14. Means for storing an animal tissue sample comprising:

a storage means having a first end and a second end and defining an internal volume into which a cutting element for collecting an animal tissue sample is inserted after collection of said sample, the storage means having at least two openings;

a first opening located at the first end of the storage means and dimensioned to enable said cutting element of the sampling means and said sample, to be received in the storage means, and wherein said cutting element seals said first opening after the insertion of the cutting element in the first opening; and

a second opening located at the second end of the storage means, distinct from said first opening, and having a removable closure means that enables access to the internal volume of the storage means.

16. The means according to claim 14, further comprising a push element disposed in moving relation to the cutting element such that the movement of the push element urges the sample from the cutting element and into the storage means, and wherein the first opening of the storage means is dimensioned to receive at least a portion of the push element, and whereby the push element seals the sample means once received thereby.

17. An animal tissue sampling device comprising:

a sampling means having at least one cutting element for cutting an animal tissue sample from an animal,

a push element disposed in moving relation to the sampling means; and

a storage means having a first end and a second end and defining an internal volume for storing a sample of animal tissue, wherein the push element of the sampling means is dimensioned to be inserted in the storage means, the storage means having at least two openings;

a first opening located at the first end of the storage means and dimensioned to enable said push element of the sampling means and said sample, to be received in the storage means, and wherein said push element seals said first opening after the insertion of the push element in the first opening, and

a second opening located at the second end of the storage means, distinct from said first opening and having a removable closure means that enables access to the internal volume of the storage means; and

wherein the movement of the push element relative to the cutting element urges the sample from the cutting element and into the storage means.

18. An animal tissue sampling device comprising:

a sampling means having at least one cutting element for collecting an animal tissue sample from an animal, and

a storage tube defining an internal volume for storing a sample of animal tissue, wherein the at least one cutting element of the sampling means is dimensioned to be inserted in the storage tube, the storage tube having at least a first opening located at a first end and a second opening located at a second end;

said first opening dimensioned to enable said cutting element of the sampling means and said sample, to be received in the storage tube, and wherein said cutting element seals said first opening after the insertion of the cutting element in the first opening; and

said second opening distinct from said first opening and having a removable closure means that enables access to the inside of the storage tube.
