Heart-lung machine with semi-autonomous initiation mode
View Patent ↗This document describes medical systems that have features for initiating operational settings during a start-up process. For example, this document describes heart-lung machine systems that are programmed and integrated with features that perform semi-autonomous start-up procedures.
1. A heart-lung machine system comprising:
an arterial pump;
a reservoir level detector system comprising two reservoir level detectors and by which a level of fluid in a reservoir is maintainable between the two reservoir level detectors;
a user interface; and
a central computer system configured to:
query the reservoir level detector system to determine whether the reservoir level detector system is active or inactive;
in response to determining that the reservoir level detector system is inactive, automatically activate the reservoir level detector system;
in response to the automatic activation of the reservoir level detector system:
(i) automatically generate an indication for display on the user interface that the reservoir level detector system is active, and
(ii) automatically prevent alarms related to detection of a lack of fluid by the reservoir level detector system from being generated; and
after the automatic prevention of the alarms related to the detection of the lack of fluid by the reservoir level detector system, discontinue the automatic prevention of the alarms in response to a first detection of fluid by the reservoir level detector system.
2. The heart-lung machine system of claim 1 , further comprising an air detector, and wherein the central computer system is further configured to:
query the air detector to determine whether the air detector is active or inactive; and
in response to determining that the air detector is inactive, automatically activate the air detector.
3. The heart-lung machine system of claim 1 , further comprising a fast clamp, and wherein the central computer system is further configured to:
query the fast clamp to determine whether the fast clamp is active or inactive; and
in response to determining that the fast clamp is inactive, automatically activate the fast clamp by closing the fast clamp.
4. The heart-lung machine system of claim 1 , further comprising a venous occluder, and wherein the central computer system is further configured to:
query the venous occluder to determine whether the venous occluder is active or inactive; and
in response to determining that the venous occluder is inactive, automatically activate the venous occluder by adjusting the venous occluder to a pre-configured occlusion setting.
5. The heart-lung machine system of claim 1 , wherein the arterial pump is a centrifugal pump, and wherein the central computer system is further configured to:
query the centrifugal pump to determine whether the centrifugal pump is active or inactive; and
in response to determining that the centrifugal pump is inactive, automatically activate the centrifugal pump by adjusting the centrifugal pump to a pre-configured RPM setting.
6. The heart-lung machine system of claim 5 , wherein the central computer system is configured to stop adjusting the centrifugal pump to the pre-configured RPM setting in response to a manual input to the heart-lung machine system that effects the pre-configured RPM setting of the centrifugal pump.
7. A method of operating a heart-lung machine system, the method comprising:
querying, by a central computer system of the heart-lung machine system, a reservoir level detector system of the heart-lung machine system to determine whether the reservoir level detector system is active or inactive, wherein the reservoir level detector system comprises two reservoir level detectors;
in response to determining that the reservoir level detector system is inactive, automatically activating, by the central computer system of the heart-lung machine system, the reservoir level detector system;
in response to the automatic activation of the reservoir level detector system, automatically preventing, by the central computer system of the heart-lung machine system, alarms related to detection of a lack of fluid by the reservoir level detector system from being generated; and
discontinuing, by the central computer system of the heart-lung machine system, the automatic prevention of the alarms in response to a first detection of fluid by the reservoir level detector system after the automatic prevention of the alarms.
8. The method of claim 7 , further comprising:
querying, by the central computer system, a centrifugal pump of the heart-lung machine system to determine whether the centrifugal pump is active or inactive; and
in response to determining that the centrifugal pump is inactive, automatically activating the centrifugal pump by the central computer system.
9. The method of claim 8 , wherein automatically activating the centrifugal pump includes adjusting, by the central computer system, the centrifugal pump to a pre-configured RPM setting.
10. The method of claim 9 , further comprising stopping, by the central computer system, adjusting the centrifugal pump to the pre-configured RPM setting in response to a manual input to the heart-lung machine system that effects the pre-configured RPM setting of the centrifugal pump.
11. The method of claim 7 , further comprising:
querying, by the central computer system, an air detector of the heart-lung machine system to determine whether the air detector is active or inactive; and
in response to determining that the air detector is inactive, automatically activating, by the central computer system, the air detector.
12. The method of claim 7 , further comprising:
querying, by the central computer system, a fast clamp of the heart-lung machine system to determine whether the fast clamp is active or inactive; and
in response to determining that the fast clamp is inactive, automatically activating, by the central computer system, the fast clamp.
13. The method of claim 12 , wherein the activating the fast clamp includes closing the fast clamp.
14. The method of claim 7 , further comprising:
querying, by the central computer system, a venous occluder of the heart-lung machine system to determine whether the venous occluder is active or inactive; and
in response to determining that the venous occluder is inactive, automatically activating, by the central computer system, the venous occluder.
15. The method of claim 14 , wherein activating the venous occluder comprises adjusting the venous occluder to a pre-configured occlusion setting.
16. The method of claim 15 , wherein the pre-configured occlusion setting is 50%.
