Abstract

A urinary catheter assembly that can reduce the need for a user to handle the urinary catheter directly, thereby reducing the likelihood of a urinary tract infection and making the catching process less messy. In one aspect, a urinary catheter apparatus and methods for voiding a human'"'"'s bladder and enabling a human patient to void his or her bladder are provided.

Claims

1. An apparatus comprising:

a urinary catheter having a proximal end portion defining a urine inlet opening and a distal end defining a urine outlet opening;

a sheath having a front end portion defining a front opening and a rear end defining a rear opening, and a rear end connector attached to said rear end of said sheath to define a discharge end of the apparatus; and

a suction cup attached directly to said rear end connector wherein, during use, said suction cup secures said discharge end of the apparatus to a surface of a toilet;

wherein said apparatus is configured such that at least a portion of said urinary catheter is within said sheath during storage and use,

wherein said apparatus is configured such that said distal end of said urinary catheter moves toward said front end portion of said sheath during use, thereby increasing the distance between said distal end of said urinary catheter and said rear end of said sheath, and

wherein, during use, urine flows into said urine inlet opening, out of said urine outlet opening, and out of said rear opening.

2. The apparatus of claim 1, wherein said urinary catheter is between fifteen and fifty-five centimeters in length.

3. The apparatus of claim 1, wherein said urinary catheter is made of polyvinyl chloride.

4. The apparatus of claim 1, wherein said proximal end portion defines a second urine inlet opening.

5. The apparatus of claim 1, wherein said urine outlet opening is oval-shaped.

6. The apparatus of claim 1, wherein said distal end defines said urine outlet'"'"'opening at the end of said urinary catheter.

7. The apparatus of claim 1, wherein said sheath is made of polyvinyl chloride.

8. The apparatus of claim 1, wherein said front end portion defines said front opening at the end of said sheath.

9. The apparatus of claim 1, wherein said apparatus is configured such that said urinary catheter is completely within said sheath during storage.

10. The apparatus of claim 9, wherein said front opening and said rear opening are sealed during storage.

11. The apparatus of claim 1, wherein said apparatus is configured such that, during storage, said proximal end portion is proximate to said front end portion and said distal end is proximate to said rear end.

12. The apparatus of claim 1, wherein said apparatus is configured such that at least a portion of said urinary catheter remains within said sheath during use.

13. The apparatus of claim 1, wherein, during use, urine flows out of said urine outlet opening, along a lumen of said sheath toward said rear opening, and out of said rear opening.

14. The apparatus of claim 1, further comprising a package enclosing said urinary catheter and said sheath.

15. The apparatus of claim 14, wherein said urinary catheter and said sheath are coiled inside said package.

16. The apparatus of claim 14, wherein said package comprises a sealed package.

17. The apparatus of claim 1, further comprising a distal end connector defining a distal connector opening, said distal end connector being attached to said distal end.

18. The apparatus of claim 17, further comprising a front end connector defining a front connector opening, said front end connector being attached to said front end portion.

19. The apparatus of claim 18, wherein, during use, said apparatus is configured such that said distal end connector interfaces with said front end connector, thereby forming a seal to allow urine to flow out of said urine outlet opening, through said distal connector opening and said front connector opening, and out of said rear opening.

20. The apparatus of claim 1, further comprising:

an extension tube attachable to said rear end connector.

21. The apparatus of claim 1, further comprising a handle attached to said rear end connector that is operable to disengage said rear end connector from said toilet.

22. The apparatus of claim 1, further comprising an introducer tip defining an insertion opening, said introducer tip being attached to said front end portion of said sheath, said apparatus configured such that said proximal end portion of said urinary catheter protrudes through said front opening of said sheath to communicate with said insertion opening.

23. The apparatus of claim 1, further comprising lubrication, wherein said urinary catheter is coated by said lubrication.

24. The apparatus of claim 23, wherein said lubrication comprises a water-based lubricant.
