Anti-reflux mechanism for urine collection systems
View Patent ↗A urine collection system includes an anti-flux mechanism to reduce the amount of urine that may flow from within the collection bag back into the urine meter. The urine collection system includes a urine meter, a collection member defining at least a first opening for receiving urine from the urine meter and a shield positioned adjacent the opening of the collection member. The shield is affixed to the collection member at predetermined connection points along a periphery of the shield whereby urine flows between the connection points from the urine meter to the collection member. The shield may be affixed to an internal surface of the bag. The shield may be spot welded to the collection member at the connection points. The shield may include at least a first slot configured to permit the passage of fluid therethrough.
1. A urine collection system, which comprises:
a urine meter having a volume to accommodate urine therein;
a collection member connected to the urine meter and defining at least a first opening for receiving urine from the urine meter; and
a shield covering the at least first opening of the collection member and being permanently affixed to the collection member at predetermined connection points along a periphery of the shield such that urine must flow between the connection points to pass from the urine meter to the collection member.
2. The urine collection system according to claim 1 wherein the shield is affixed to an internal surface of the collection member.
3. The urine collection system according to claim 1 wherein the shield is spot welded to the collection member at the connection points.
4. The urine collection system according to claim 1 , further including a flap disposed between the shield and the collection member.
5. The urine collection system according to claim 4 , wherein the flap is configured to deflect towards the collection member as urine flows from the urine meter to the collection member.
6. The urine collection system according to claim 1 , wherein the urine meter is configured to be tilted to effect urine drainage from the urine meter to the collection member.
7. A urine collection system, which comprises:
a urine meter having a volume to accommodate urine therein, the urine meter defining a dump port;
a collection member connected to the urine meter and defining an opening for receiving urine from the urine meter; and
a guard covering the dump port of the urine meter, the guard having a plurality of passages formed through the guard which communicate the dump port with the opening in the collection member to allow passage of urine from the urine meter into the collection member, wherein the plurality of passages control the flow of fluid into the collection member and control the reflux of the fluid from the collection member into the urine meter.
8. The urine collection system according to claim 7 wherein at least some of the passages of the guard define different internal dimensions.
9. The urine collection system according to claim 8 wherein the internal dimensions of the passages of the guard increase from a lower end of the guard to an upper end of the guard.
10. The urine collection system according to claim 8 wherein the plurality of passages of the guard define a plurality of slots.
