Priming tray for priming a fluid system
A system for assisting a patient's heart has a pump, an oxygenator, a holder having a pump receiving portion for removably receiving the pump and an oxygenator receiving portion for removably receiving the oxygenator, and a harness configured to surround at least a portion of a patient's torso. The holder is connected to the harness. The system further has a brace connected to at least a portion of the harness. The brace is configured to extend behind a back portion of a user's head and to support tubing connected to at least one of the pump and the oxygenator. A priming tray and wet-to-wet connector connecting the cardiac assist system to the cannula so are also disclosed.
1. A tray for use in priming a cardiac assist system, the tray comprising:
a body having a base wall and a plurality of side walls upstanding from the base wall to define an interior reservoir configured for holding a volume of fluid, the base wall defining a first planar base surface and a second planar base surface extending at an obtuse angle from the first planar surface;
an inlet port extending through a first one of the plurality of side walls and having an inlet valve connector configured to receive a first connecting tubing of a first component of a cardiac assist system; and
an outlet port extending through the first one of the plurality of side walls or a second one of the plurality of side walls and having an outlet valve connector configured to receive a second connecting tubing of a second component of the cardiac assist system,
wherein the body is positionable on a level surface and tiltable from a first position in which the body is supported on the first planar base surface to a second position where the body is tilted to rest on the second planar base surface to prime the cardiac assist system with the fluid in the tray via gravity.
2. The tray according to claim 1 , wherein the inlet port is at a higher position relative to the outlet port when the body is in the second position.
3. The tray according to claim 1 , wherein the inlet valve connector is configured to receive the first connecting tubing such that an end of the tubing extends into the interior reservoir.
4. The tray according to claim 1 , wherein the inlet valve connector comprises an inlet valve having a seal configured to prevent leakage of the fluid around the first connecting tubing when the first connecting tubing of the fluid system is inserted through the inlet valve.
5. The tray according to claim 4 , wherein the seal of the inlet valve is configured to automatically reseal the interior reservoir when the first connecting tubing is removed from the inlet valve.
6. The tray according to claim 1 , wherein the outlet valve connector is configured to receive the second connecting tubing such that the second connecting tubing of the fluid system extends into the interior reservoir.
7. The tray according to claim 1 , wherein the outlet valve connector comprises an outlet valve having a seal configured to prevent leakage of the fluid around the second connecting tubing when the second connecting tubing of the fluid system is inserted through the outlet valve.
8. The tray according to claim 7 , wherein the seal of the outlet valve is configured to automatically reseal the interior reservoir when the second connecting tubing is removed from the outlet valve.
9. The tray according to claim 1 , further comprising a removable lid configured to enclose at least a portion of the interior reservoir.
10. The tray according to claim 1 , wherein the interior reservoir is angled or tapered toward the outlet port along the second planar base surface.
11. A system for use in priming a cardiac assist system, the system comprising:
a tray including:
a body having a base wall and a plurality of side walls upstanding from the base wall to define an interior reservoir configured for holding a volume of fluid, the base wall defining a first planar base surface and a second planar base surface extending at an obtuse angle from the first planar surface;
an inlet port extending through a first one of the plurality of side walls and having an inlet valve connector;
an outlet port extending through the first one of the plurality of side walls or a second one of the plurality of side walls and having an outlet valve connector; and
connecting tubing with a first end connectable to a first component of the cardiac assist system and a second end connectable to a second component of the cardiac assist system;
wherein the body is positionable on a level surface and tiltable from a first position in which the body is supported on the first planar base surface to a second position where the body is tilted to rest on the second planar base surface, and
wherein, with the first end of the connecting tubing inserted into the inlet valve connector and the second end of the connecting tubing inserted into the outlet valve connector, a fluid circuit is formed whereby the interior reservoir is in fluid communication with both the first component of the cardiac assist system and the second component of the cardiac assist system, and when the body is tilted from the first position to the second position, the fluid flows through the inlet port to the outlet port by gravity such that the fluid can more easily flow through the cardiac assist system from the inlet port to the outlet port to prime the cardiac assist system with the fluid in the tray via gravity.
12. The system according to claim 11 , wherein the inlet port is at a higher position relative to the outlet port when the body is in the second position.
13. The system according to claim 11 , wherein the inlet valve connector comprises an inlet valve having a seal configured to prevent leakage of the fluid around the connecting tubing when the first end of the connecting tubing is inserted through the inlet valve.
14. The system according to claim 13 , wherein the seal of the inlet valve is configured to automatically reseal the interior reservoir when the first end of the connecting tubing is removed from the inlet valve.
15. The system according to claim 11 , wherein the outlet valve connector comprises an outlet valve having a seal configured to prevent leakage of the fluid around the connecting tubing when the second end of the connecting tubing is inserted through the outlet valve.
16. The system according to claim 15 , wherein the seal of the outlet valve is configured to automatically reseal the interior reservoir when the second end of the connecting tubing is removed from the outlet valve.
17. The system according to claim 11 , further comprising a lid removably connectable to the tray to enclose at least a portion of the interior reservoir.
18. The system according to claim 11 , wherein the interior reservoir is angled or tapered toward the outlet port.
