Abstract
Disclosed is a device for providing resuscitation or suspended state through redistribution of cardiac output to increase supply to the brain and heart for a patient. The device includes an electrically controllable redistribution component attachable to the patient to provide redistribution of the cardiac output to increase supply to the brain and heart. The redistribution component, following a predefined reaction pattern based on an electrical signal, and computer means configured to: receive a patient data which identifies physiological and/or anatomical characteristics of the patent; and provide the electrical signal for the redistribution component based on the patient data or a standard response. The device may provide mechanisms to protect the aorta and the remaining anatomy of the patient from inadvertent damage caused by the disclosed device in any usage scenario of either correct intended usage or unintended usage. Also disclosed is a method for providing resuscitation or suspended state.
Core Innovation
The invention relates to a device for providing resuscitation or suspended state through redistribution of cardiac output to increase supply to the brain and heart for a patient. The device includes an electrically or manually controllable redistribution component attachable to the patient and configured to interact with the patient to provide redistribution of the cardiac output according to a predefined reaction pattern based on an electrical signal.
A computer means receives patient data identifying physiological and/or anatomical characteristics of the patient and provides the electrical signal for controlling the redistribution component based on the patient data and a predefined definition of the electrical signal stored in memory means. Patient data generation means generate the patient data during external cardiac compression by sensing biosignals from a blood vessel or a tissue compartment, while the patient data or a standard response is used for controlling and/or presenting information to a user.
The redistribution component comprises or consists of an aortic perfusion pump, and the device further comprises a location safety mechanism for verifying a position of the aortic perfusion pump in the aorta. The location safety mechanism includes at least one first sensor capable of determining a biosignal characteristic for the aorta of the patient, and an electronic circuit configured to verify the position based on the biosignal. The disclosed concept includes safety verification using biosignal sensors, an interactive user interface, failsafe mechanisms, and feedback control.
Claims Coverage
The independent claim coverage includes five inventive features.
Resuscitation device with redistributed cardiac output toward brain and heart
A device for providing resuscitation or suspended state through redistribution of cardiac output to increase supply to the brain and heart, the device comprising an electrically or manually controllable redistribution component attachable to the patient and configured to interact with the patient to provide redistribution of the cardiac output.
Predefined reaction pattern controlled by electrical signal from patient data
The redistribution component follows a predefined reaction pattern based on an electrical signal, and computer means receive patient data identifying physiological and/or anatomical characteristics of the patient and provide the electrical signal for controlling the redistribution component based on the patient data and a predefined definition of the electrical signal stored in memory means.
Patient data generation during external cardiac compression via biosignal sensing
Patient data generation means generate the patient data during external cardiac compression by sensing biosignals from a blood vessel or a tissue compartment.
Aortic perfusion pump as redistribution component
The redistribution component comprises or consists of an aortic perfusion pump.
Location safety mechanism with biosignal-characteristic verification of pump position
A location safety mechanism comprising at least one first sensor capable of determining a biosignal characteristic for the aorta of the patient and an electronic circuit configured to verify the position of the aortic perfusion pump in the aorta based on the biosignal.
Overall, the claims center on device-based resuscitation or suspended state achieved by computer-controlled redistribution of cardiac output to preferentially increase supply to the brain and heart, coupled with patient data generation during external cardiac compression via biosignal sensing and an aorta-specific location safety mechanism to verify positioning of an aortic perfusion pump.
