Abstract

A sterilization case 1 having one or more brackets 10 which are designed to enhance the steam sterilization of a medical apparatus 30 being held in the bracket 10. The bracket 10 is designed to provide cutout areas 51 to create a gap or gaps 52 between the surface of the apparatus 30 being held and the recess in the bracket 10, and yet still securely grip and hold the apparatus 30 in the bracket. The invention is adaptable to a wide variety of different shaped apparatus 30.

Claims

1. A combination comprising, a steam sterilization case and a medical apparatus for being securely held in the sterilization case, wherein the sterilization case includes a base portion with at least one holding bracket extending from the base portion, and wherein the at least one bracket includes a recess defined by an opening at a first end for receiving the medical apparatus and an oppositely located second end and two oppositely facing walls interconnecting the first and second ends, and wherein the two oppositely facing walls of the recess have a first width therebetween for contacting and securely gripping a portion of the medical apparatus therebetween, and wherein the recess includes a cutout means located between the first width of the recess and the second end of the recess for enlarging the recess and creating a gap between the medical apparatus and at least one of the oppositely facing walls of the recess to enhance the steam circulation around the medical apparatus during steam sterilization of the medical apparatus.

2. The combination of claim 1 wherein the cutout means provides a second width between the oppositely facing walls of the recess which is larger than the first width.

3. The combination of claim 1 wherein the cutout means creates a plurality of gaps between the medical apparatus and the recess.

4. The combination of claim 1 wherein the at least one of the oppositely facing walls includes a substantially planar surface which mates with a corresponding substantially planar surface on the medical apparatus, and wherein the gap created by the cutout means is provided along a portion of said substantially planar surface of the medical apparatus.

5. The combination of claim 1 wherein the at least one bracket is made from a non-metallic material.

6. A method of enhancing sterilization comprising the following steps:

a) providing a medical apparatus and a steam sterilization case, the case having a base portion with at least one holding bracket extending from the base portion;

b) providing the at least one bracket with a recess defined by an opening at a first end for receiving the medical apparatus and an oppositely located second end and two oppositely facing walls interconnecting the first and second ends;

c) providing the two oppositely facing walls of the recess with a first width therebetween for contacting and securely gripping a portion of the medical apparatus therebetween;

d) providing the recess with a cutout means located between the first width of the recess and the second end of the recess for enlarging the recess and creating a gap between the medical apparatus and at least one of the oppositely facing walls of the recess to enhance the steam circulation around the medical apparatus during steam sterilization of the medical apparatus.

7. The method of claim 6 wherein the method further includes the step of providing the cutout means with a second width between the oppositely facing walls of the recess which is larger than the first width.

8. The method of claim 6 wherein the method further includes the step of providing the cutout means such that the cutout means creates a plurality of gaps between the medical apparatus and the recess.

9. The method of claim 6 wherein the method further includes the step of providing the at least one of the oppositely facing walls with a substantially planar surface to mate with a corresponding substantially planar surface on the medical apparatus, and thus, providing the gap created by the cutout means alongside a portion of said substantially planar surface of the medical apparatus.

10. The method of claim 6 wherein the method further includes the step of manufacturing the at least one bracket from a nonmetallic material.
