Medical instrument retainer assembly and method of making the retainer
View Patent ↗A retainer assembly for retaining a medical device in a container having a perforated wall includes a retainer with a rigid support portion having at least one leg and a flexible, resilient instrument holding portion intimately bonded to the support portion so that the retainer is devoid of cracks and crevices between said portions. Each leg has a free end and an axial passage extending into the leg from that end so that the retainer may be positioned on the container wall with each opening in register with a perforation therein. A fastener extends into the passage of each leg and the underlying perforation from below the wall to anchor each leg to the wall under pressure thereby providing a seal between each leg and the wall. Various retainer embodiments and a method for making same are also disclosed.
1. A retainer assembly for retaining a medical device in a container having a wall with perforations, said retainer assembly comprising
a retainer including a rigid support portion having at least one leg, a flexible, resilient instrument holding portion intimately bonded to the support portion so that the retainer is devoid of cracks and crevices between said portions, each said leg extending from the holding portion to a free end, and an axial passage extending into each leg from said free end thereof so that the retainer may be positioned on said wall with each axial passage in register with a perforation in said wall, wherein said wall is contacted by said leg only at a surface directly underneath said leg, and
a fastener extending into the passage of each leg and the underlying perforation from below said wall to anchor each leg to said wall under pressure; and,
a seal between each leg and the wall.
2. The assembly defined in claim 1 wherein each leg is formed with a peripheral knife edge at the free end thereof.
3. The assembly defined in claim 1 wherein said holding portion includes a wall extension surrounding each leg of the support portion.
4. The assembly defined in claim 3 wherein the wall extension surrounding each leg protrudes beyond the free end of that leg to form a flexible resilient sealing lip at the periphery of said free end.
5. The assembly defined in claim 1 wherein
the passage in each leg is threaded, and
each fastener is a threaded fastener.
6. The assembly defined in claim 1 wherein each fastener is a rivet or friction pin.
7. The assembly defined in claim 1 wherein
the support portion comprises an elongated beam having locking surfaces, and
said holding portion comprises an elongated blade which is coextensive with the beam and which mechanically interfits with said surfaces.
8. The assembly defined in claim 1 wherein
the support portion comprises a rigid post, and
the holding portion comprises a sleeve surrounding the post except at an end portion thereof which constitutes said at least one leg.
9. The assembly defined in claim 8 wherein the support portion also includes
an additional rigid post spaced parallel to said post;
an additional sleeve surrounding the additional post except at an end portion thereof which constitutes a second leg, and
a web extending between said sleeve and said additional sleeve.
10. The assembly defined in claim 1 and further including at least one cut-out in said holding portion for receiving a medical device.
11. The assembly defined in claim 1 wherein the support portion is of a plastic material or metal.
12. The assembly defined in claim 11 wherein the holding portion is of a silicone material.
13. The assembly of claim 1 , further comprising a sealing flange formed between the leg and the wall thereby providing the seal.
14. The assembly of claim 1 , wherein each leg is mounted about only one perforation.
15. The assembly of claim 1 , further comprising a fluid path between the wall and the retainer.
16. The assembly of claim 1 , wherein the at least one leg further comprises at least two legs and, wherein the assembly further comprises an air gap formed between the legs, above the wall, and beneath the retainer.
17. The assembly of claim 1 , wherein the at least one leg further comprises a plurality of legs and each of the legs is mounted about only one perforation.
