Abstract

Eliminating leaks of molded fluid channels by providing a front housing, rear housing, and a gasket, wherein the front housing has one or more molded fluid channels and one or more seal channels, and wherein at least a portion of the gasket is located between the front and rear housing; molding the gasket onto the rear housing to create a single unit, wherein the gasket has one or more seal lips configured and dimensioned to couple with the one or more seal channels; and assembling the front housing to the rear housing having the gasket, wherein the one or more seal lips couple with the seal channels. A surgical cassette manifold having a front and rear housing, and a gasket therebetween. The front housing having molded fluid channels that mate with the gasket and the gasket having multiple valves and a sensor/diaphragm accessible through the rear housing.

Claims

1. A method of eliminating leaking of molded fluid channels, comprising:

providing a front housing, rear housing, and a gasket,

wherein the front housing comprises one or more molded fluid channels and one or more seal channels, and

wherein at least a portion of the gasket is located between the front housing and the rear housing,

molding the gasket onto the rear housing to create a single unit;

wherein the gasket comprises one or more seal lips configured and dimensioned to couple with the one or more seal channels; and

assembling the front housing to the rear housing having the gasket, wherein the one or more seal lips couple with the seal channels.

2. The method of claim 1, wherein the seal channels are located on an outside perimeter of the molded fluid channels.

3. The method of claim 1, wherein the one or more seal lips extend substantially perpendicular from a surface of the gasket.

4. The method of claim 1, wherein the seal lip is tapered.

5. The method of claim 1, wherein the molded fluid channels are substantially perpendicular with a surface of the front housing.

6. The method of claim 1, wherein the seal channels are substantially perpendicular with a surface of the front housing.

7. The method of claim 1, wherein the seal lips are configured and dimensioned as pre-alignment structures enabling proper assembly with corresponding seal channels.

8. The method of claim 1, further comprising one or more alignment pins and corresponding pin holes, wherein after molding the gasket onto the rear housing to create a single unit;

coupling the alignment pins with the corresponding pin holes.

9. The method of claim 8, after assembling the front housing to the rear housing having the gasket,

ultrasonically welding the front housing to the rear housing.

10. The method of claim 8, after assembling the front housing to the rear housing having the gasket,

press fitting the front housing to the rear housing.

11. A surgical cassette manifold, comprising:

a front housing, a rear housing, and a gasket,

wherein the front housing comprises one or more molded fluid channels and one or more seal channels,

wherein the gasket is coupled with the rear housing and at least a portion of the gasket is located between the front housing and the rear housing, and

wherein the gasket comprises one or more seal lips configured and dimensioned to couple with the one or more seal channels.

12. The surgical cassette manifold of claim 11, wherein further comprises a reservoir, wherein the reservoir comprises a first portion with a first circumferential edge located in the front housing, a second portion with a second circumferential edge located in the rear housing, and wherein at least a portion of the gasket is located between the first and second circumferential edge when the front housing and rear housing are assembled.

13. The surgical cassette manifold of claim 12, wherein upon assembly of the surgical cassette manifold, the gasket creates a mechanical seal between the first portion and the second portion of the reservoir.

14. The surgical cassette manifold of claim 11, wherein the seal channels are located on an outside perimeter of the molded fluid channels.

15. The surgical cassette manifold of claim 11, wherein the one or more seal lips extend substantially perpendicular from a surface of the gasket.

16. The surgical cassette manifold of claim 11, wherein the seal lip is tapered.

17. The surgical cassette manifold of claim 11, wherein the molded fluid channels are substantially perpendicular with a surface of the front housing.

18. The surgical cassette manifold of claim 11, wherein the seal channels are substantially perpendicular with a surface of the front housing.

19. The surgical cassette manifold of claim 11, wherein the seal lips are configured and dimensioned as pre-alignment structures enabling proper assembly with the seal channels.

20. The surgical cassette manifold of claim 11, wherein the rear housing further comprises one or more alignment pins and the front housing further comprises one or more corresponding pin holes, wherein the one or more alignment pins and one or more pin holes are configured and dimensioned to mate upon assembly of the front housing and rear housing.
