Abstract

A media-dispensing apparatus for testing body fluids and a method of using the same are disclosed. The apparatus includes a housing having a lower portion and an upper portion, and an elongated tubular member having a distal opening adjacent a distal end thereof. The elongated tubular member includes a first lumen within the elongated tubular member extending from the lower portion of the housing to the distal opening and includes a second lumen within the elongated tubular member extending from the upper portion of the housing to the distal opening. A media strip is dispensable from the lower portion of the housing, through the first lumen, out the distal opening of the elongated tubular member, through the second lumen and into the upper portion of the housing.

Claims

1. A media-dispensing apparatus, comprising:

a housing including a lower portion and an upper portion; and

an elongated tubular member extending distally from the housing, the elongated tubular member including a distal opening adjacent a distal end thereof, a first lumen therein extending from the lower portion of the housing to the distal opening and a second lumen therein extending from the upper portion of the housing to the distal opening;

wherein a media strip is dispensable from the lower portion of the housing, through the first lumen, out the distal opening of the elongated tubular member, through the second lumen and into the upper portion of the housing.

2. The media-dispensing apparatus according to claim 1, further comprising a separator disposed at least partially within the housing and which separates the lower portion of the housing from the upper portion of the housing.

3. The media-dispensing apparatus according to claim 1, further comprising a central hub disposed in the lower portion of the housing and providing a surface for the media strip to wrap around.

4. The media-dispensing apparatus according to claim 1, further comprising at least a single one-way passage valve within at least one of the housing, the elongated tubular member and an interface therebetween, the one-way passage valve allowing the media strip to travel in a single direction therethrough.

5. The media-dispensing apparatus according to claim 4, wherein the one-way passage valve is disposed at least partially within the second lumen.

6. The media-dispensing apparatus according to claim 1, a separating member of the elongated tubular member separates the first lumen from the second lumen, and wherein a distal-most end of the separating member is rounded.

7. The media-dispensing apparatus according to claim 1, wherein one lumen extends farther distally than the other lumen.

8. The media-dispensing apparatus according to claim 1, further comprising a seal disposed within at least one of the first lumen and the second lumen, the seal being configured to allow the media strip to pass therethrough and being configured to limit the passage of body fluids during use of the media-dispensing apparatus.

9. The media-dispensing apparatus according to claim 8, wherein the seal is disposed adjacent a distal end of the first lumen.

10. The media-dispensing apparatus according to claim 1, further comprising an aperture disposed through a portion of the upper portion of the housing, the aperture enabling at least a portion of the media strip to exit the upper portion of the housing.

11. The media-dispensing apparatus according to claim 1, further comprising a cover hingedly coupled to the housing which is moveable between a first position where the cover is in proximity with the upper portion of the housing and at least a second position where the cover is spaced apart from the upper portion of the housing.

12. The media-dispensing apparatus according to claim 1, further comprising a cutting instrument disposed on at least one of the upper portion and the lower portion of the housing for cutting the media strip.

13. The media-dispensing apparatus according to claim 11, further comprising a cutting instrument disposed on at least one of the housing and the cover for cutting the media strip.

14. The media-dispensing apparatus according to claim 13, wherein the cutting instrument is disposed on the cover and wherein moving the cover from the second position towards the first position cuts the media strip.

15. The media-dispensing apparatus according to claim 1, wherein the media strip is made of a material which is able to at least detect or identify at least one abnormality or at least one infection.

16. The media-dispensing apparatus according to claim 1, wherein at least a portion of the media strip is a color changing medium.

17. A method of testing body fluids, comprising the steps of:

providing a media-dispensing apparatus including a housing having a lower portion and an upper portion, an elongated tubular member extending distally from the housing and having a distal opening adjacent a distal end thereof, a first lumen disposed within the elongated tubular member extending from the lower portion of the housing to the distal opening, a second lumen disposed within the elongated tubular member extending from the upper portion of the housing to the distal opening, and a media strip extending from the lower portion of the housing, through the first lumen, out the distal opening of the elongated tubular member, through the second lumen and into the upper portion of the housing;

placing at least the distal opening of the elongated tubular member adjacent a surgical site such that a portion of the media strip contacts the surgical site; and

advancing the media strip such that the portion of the media strip that contacted the surgical site advances at least through the second lumen.

18. The method of testing body fluids according to claim 17, wherein the media-dispensing apparatus further includes a cover hingedly coupled to the housing and a cutting instrument disposed on a portion of at least one of the housing and the cover, the cover being moveable between a first position where the cover is in proximity with the upper portion of the housing and at least a second position where the cover is spaced apart from the upper portion of the housing, such that moving the cover from the second position towards the first position cuts the media strip and wherein the method further includes the step of cutting the media strip.

19. The method of testing body fluids according to claim 17, wherein at least the distal opening of the elongated tubular member remains adjacent the surgical site as the media strip is advanced.

20. The method of testing body fluids according to claim 17, wherein at least a portion of the media-dispensing apparatus is inserted near a patient'"'"'s abdomen.
