Abstract
The invention relates to a device for treating an individual suffering from cardiac or circulatory arrest or from a stroke, comprising a blood withdrawal device (BE) that is applied to the individual (P), an analysis unit (BA) which is directly or indirectly connected to the blood withdrawal device for detecting a blood analysis result (BAE) providing at least one characteristic of the blood, directly or indirectly connected to a blood return device (BR) that is applied to the individual (P) and is designed to deliver a substance to the individual via the return device (BR).
Core Innovation
The invention provides a treatment of cardiac arrest by withdrawing blood from a patient's or an animal's circulatory system during cardiac arrest. During the cardiac arrest, a reperfusion solution containing at least one substance is introduced into the circulatory system, and modified blood is formed by addition of the at least one substance or at least one other substance into the withdrawn blood.
A blood analyser provides automated blood analysis during the treatment of the cardiac arrest and determines a plurality of parameters of the blood, including at least pO2, pCO2 and pH, representing a current condition of the patient or animal during the treatment. The blood analyser provides an output representing the automated blood analysis during the treatment, and a storage stores during the cardiac arrest at least two substances, from which the at least one substance or the at least one other substance is selected for treatment.
Based on the automated analysis, means for selecting a type and quantity of the at least one substance or the at least one other substance determine what is withdrawn from the storage. Means for introducing introduce during the cardiac arrest the selected substance into the circulatory system and then introduce the modified blood containing that selected substance or other selected substance to provide whole body reperfusion of the circulatory system during the treatment of the cardiac arrest.
Claims Coverage
Two independent claims are identified. Across them, the coverage includes automated blood analysis of multiple blood parameters, selection of substance type and quantity from at least two stored substances, and introduction of modified blood to provide whole-body reperfusion that lessens or prevents ischemic tissue damage.
Automated blood analysis with parameter output during cardiac arrest
A blood analyser providing automated blood analysis during the treatment of the cardiac arrest, determining a plurality of parameters including at least pO2, pCO2 and pH, and providing an output representing the automated blood analysis during the treatment.
Storage of at least two substances for reperfusion treatment
A storage for storing during the treatment of the cardiac arrest at least two substances from which the at least one substance or the at least one other substance is selected for treatment.
Selection of substance type and quantity based on automated analysis
Means for selecting, based on the automated analysis, a type and quantity of the at least one substance or the at least one other substance to be withdrawn from the storage.
Whole body reperfusion using introduced modified blood
Means for introducing, during the treatment of the cardiac arrest, the selected substance into the circulatory system and then the modified blood containing that selected substance or other selected substance to provide whole body reperfusion of the circulatory system during the treatment of the cardiac arrest.
Modified blood formation by adding at least one substance to withdrawn blood
A system withdrawing blood during cardiac arrest and introducing at least one substance into the withdrawn blood to form modified blood, which is introduced into the circulatory system to provide whole body reperfusion during the treatment of the cardiac arrest.
Automated introduction of modified blood during cardiac arrest
Means for automatically introducing, during the treatment of the cardiac arrest, the modified blood into the circulatory system to provide whole body reperfusion that lessens or prevents ischemic tissue damage during the treatment of the cardiac arrest.
The independent claim set centers on automated blood analysis during cardiac arrest, selection of substance type and quantity from a storage containing at least two substances, and introduction of modified blood to achieve whole-body reperfusion that lessens or prevents ischemic tissue damage.
Stated Advantages
Lessens or prevents ischemic tissue damage during the treatment of the cardiac arrest.
Documented Applications
Treatment of cardiac arrest by providing whole body reperfusion during cardiac arrest.
Treatment of cardiac insufficiency and/or stroke is described as applicable in the provided content.
