Abstract

A method for collecting nasal secretions includes providing a collection apparatus having an elongated collection arm having one end portion adapted for introduction into the nose, a suctioning arm connected to a vacuum source and a collection cup connected to the opposite ends of both arms. Due to the vacuum from the suctioning arm, nasal secretions are drawn from the nose through the collection arm and deposited in the collection cup. The method of the invention includes stimulating the lining of the nose so that an adequate volume of secretions may be collected, then inserting the one end of the collection arm into the nose and causing vacuum to be communicated to the collection arm for drawing nasal secretions therethrough into the collection cup.

Claims

1. The method of collecting uncontaminated and undiluted nasal secretions from a nose including an inferior meatus, comprising,

providing a collection apparatus including an elongated collection arm and a suctioning arm in communication with a collection cup,

connecting said suctioning arm to a source of vacuum,

inserting one end of said collection arm into the nose,

directing the collection arm away from the inferior meatus thereby avoiding contamination by lacrimal secretions,

maintaining the nose free of contamination and dilution factors,

causing vacuum to be communicated from said suctioning arm to said collection arm,

and thereby drawing nasal secretions into said collection arm and depositing said secretions in said collection cup.

2. The method of claim 1 further comprising stimulating the lining of a nose to produce nasal secretions.

3. The method of claim 2 wherein stimulating the lining of a nose comprises inserting a pledget into one side of the nose, leaving said pledget in place for a limited period of time, and removing said pledget.

4. The method of claim 3 wherein said pledget comprises cellulose acetate material.

5. The method of claim 1 further comprising spreading the nasal opening with a nasal speculum while inserting the collection arm.

6. The method of claim 1 further comprising using a separate collection apparatus and collection cup for each side of the nose.

7. The method of claim 1 further comprising regulating the application of vacuum from said suctioning arm to said collection arm.

8. The method of claim 1 further comprising shining a light into the nose whereby the collection arm may be inserted into the nose under direct vision.

9. The method of claim 1 further comprising removing the collection cup from said apparatus, capping the same and saving said cup and the secretions therein for analysis.

10. The method of collecting nasal secretions, comprising,

providing a collection apparatus including an elongated collection arm and a suctioning arm in communication with a collection cup,

connecting said suctioning arm to a source of vacuum,

inserting one end of said collection arm into the nose,

causing vacuum to be communicated from said suctioning arm to said collection arm,

and thereby drawing nasal secretions into said collection arm and depositing said secretions in said collection cup,

stimulating the lining of a nose to produce nasal secretions by inserting a pledget into one side of the nose, leaving said pledget in place for a limited period of time, and removing said pledget, and

cleaning said pledgets for removing trace metals prior to insertion into the nose.

11. The method of collecting nasal secretions, comprising,

providing a collection apparatus including an elongated collection arm and a suctioning arm in communication with a collection cup,

connecting said suctioning arm to a source of vacuum,

inserting one end of said collection arm into the nose, causing vacuum to be communicated from said suctioning arm to said collection arm,

and thereby drawing nasal secretions into said collection arm and depositing said secretions in said collection cup,

removing the collection cup from said apparatus, capping the same and freezing said cup and the secretions therein.
