Abstract

The invention relates to systems and/or apparatuses capable of sterilizing medical products, preferably reusable urinary catheters, or other products using radiation. The apparatus of the present invention can be efficiently configured and designed to provide sterilization of the surfaces of a medical device by emitting radiation in a range sufficient and effective to destroy contaminants including pathogens and microorganisms. According to one preferred embodiment, radiation emitting diodes are placed in an array such that radiation is emitted into the interior of the apparatus enclosing the medical device for sterilization. Preferably, the systems and/or apparatuses can repeatedly sterilize medical products (e.g., reusable urinary catheters) without damaging them.

Claims (35)

1. A reusable urinary catheter product, comprising:

a container comprising a housing and a re-closable lid, the housing having a first compartment defining a sterilization chamber and a second compartment defining an interior, the first compartment and second compartment being separated by one or more walls that allow the passage of a sterilization and disinfecting media;

a urinary catheter located in the first compartment;

a fluid adapted to enhance sterilizing of the urinary catheter, wherein the fluid contains one or more of the following: water, hydrogen peroxide, or silver particles; and

a sterilization and disinfection source located in the second compartment, wherein the sterilization and disinfecting media emitted from the sterilization and disinfection source passes through the one or more walls and into the first compartment.

2. The reusable urinary catheter product of claim 1 , wherein the one or more walls includes a UV transparent optical window.

3. The reusable urinary catheter product of claim 1 , wherein the sterilizing light source comprises one or more light emitting diodes.

4. The reusable urinary catheter product of claim 3 , wherein the one or more light emitting diodes are embedded within the one or more walls.

5. The reusable urinary catheter product of claim 1 further comprising:

a power source for powering the sterilizing light source.

6. The reusable urinary catheter product of claim 1 , wherein the sterilizing chamber further includes reflective material that reflects the sterilizing light.

7. The reusable urinary catheter product of claim 1 , wherein the sterilizing light source is a UV light source.

8. A reusable urinary catheter kit, comprising:

a housing including

a first member defined by one or more walls defining an interior,

a second member defining a lid,

and

a sterilization chamber defined by the interior and the lid, with the interior defining an access opening of the sterilization chamber;

a fluidics system connected to the sterilization chamber and configured to circulate a fluid through the sterilization chamber when the second member is in the closed condition; and

a reusable urinary catheter at least partially positioned within the sterilization chamber, wherein the second member is adjustably associated to the first member and configured to move between a closed condition in which the lid overlays the access opening to enclose the reusable urinary catheter within the chamber and an open condition in which the lid is spaced from the access opening.

9. The reusable urinary catheter kit of claim 8 , wherein the housing defines a closed loop when the second member is in the closed condition.

10. The reusable urinary catheter kit of claim 8 , wherein the sterilization chamber is fluid-tight when the second member is in the closed condition.

11. The reusable urinary catheter kit of claim 8 , wherein the fluid is adapted to enhance sterilizing of the reusable urinary catheter.

12. The reusable urinary catheter kit of claim 8 , wherein the fluid contains one or more of the following: water, hydrogen peroxide, or silver particles.

13. The reusable urinary catheter kit of claim 8 further comprising:

at least one light source associated with the sterilization chamber and configured to irradiate at least a portion of the reusable urinary catheter with sterilizing light.

14. A reusable urinary catheter product, comprising:

a housing comprising a distal section, a proximal section, and a middle section therebetween, wherein the housing includes one or more walls defining an interior and a sterilization chamber defined by the interior and a lid;

a sterilizing and lubricating fluid within the interior, the sterilizing and lubricating fluid comprising a sterilizing medium, wherein the sterilizing and lubricating fluid contains one or more of the following: water, hydrogen peroxide, or silver particles; and

a reusable catheter including a catheter shaft having a distal end portion and a proximal end portion, the catheter shaft being located within the sterilization chamber, the catheter shaft including a coating thereon, wherein the sterilizing and lubricating fluid hydrates the coating and sterilizes the catheter, the catheter being configured to repeatedly inserted into and removed from the housing.

15. The reusable urinary catheter product of claim 14 , wherein the housing further comprises a textured grip to provide an ergonomic handle.

16. The reusable urinary catheter product of claim 14 further comprising:

a micro fluid pump to pump the sterilizing and lubricating fluid into and out of the sterilization chamber.

17. The reusable urinary catheter product of claim 14 further comprising:

at least one light source associated with the sterilization chamber and configured to irradiate at least a portion of the reusable catheter with sterilizing light.
