Solution Overview

Problem

Traditional blood transfusions often trigger massive systemic inflammatory responses and are limited by the need for time-consuming remote conditioning procedures, which may not be feasible in emergency situations or when access to suitable tissue beds is unavailable.

Innovation Solution

Subjecting donors to remote conditioning prior to blood collection to release biologically active substances, which are then collected and processed into blood-derived products that can be administered to treatment subjects to reduce inflammation and provide health benefits without the need for direct remote conditioning on the recipient.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional remote conditioning procedures are applied to treatment subjects, then protection against ischemia-reperfusion injury is achieved, but the procedure is time-consuming and not feasible in emergency situations

Engineering Contradiction:
Improveprotection against ischemia-reperfusion injuryVSAvoidprocedure time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The invention applies remote conditioning to donors before blood collection, so that the protective effects are already present in the blood when transfused to the treatment subject. This eliminates the need to perform time-consuming remote conditioning procedures on the treatment subject in emergency situations, while still achieving protection against ischemia-reperfusion injury.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The invention uses donor blood as an intermediary to transfer the protective effects of remote conditioning from the donor to the treatment subject. The blood acts as a carrier that delivers bioactive substances and protective mechanisms without requiring direct application of the conditioning procedure to the treatment subject.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If traditional blood transfusions are administered to treatment subjects, then blood volume and organ perfusion are restored, but massive systemic inflammatory response is triggered

Engineering Contradiction:
Improverestoration of blood volume and organ perfusionVSAvoidsystemic inflammatory response
Core Design Contradiction:
ReliabilityVSObject-generated harmful factors

Solution Approach 1:

The invention applies remote conditioning to donors before blood collection to pre-activate protective mechanisms that counteract inflammation. This preliminary anti-action ensures that the transfused blood contains substances that will mitigate the inflammatory response when administered to the treatment subject, while still restoring blood volume and organ perfusion.

Inventive Principle:
Principle #9Preliminary anti-action

Solution Approach 2:

The invention changes the biochemical parameters of the blood by subjecting donors to remote conditioning, which alters the composition and properties of the blood. This results in blood with modified inflammatory profiles and enhanced protective capabilities, allowing restoration of blood volume without triggering massive systemic inflammation.

Inventive Principle:
Principle #35Parameter changes

3Reliability

If remote conditioning is applied to treatment subjects, then health benefits are achieved, but access to suitable tissue beds may not be available in severe trauma situations

Engineering Contradiction:
Improvehealth benefitVSAvoidaccess to tissue bed
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The invention uses donor blood as an intermediary to deliver the health benefits of remote conditioning without requiring direct access to the treatment subject's tissue beds. The blood carries protective bioactive substances from the donor (who received remote conditioning) to the treatment subject, making the therapy feasible even when tissue bed access is unavailable due to severe trauma.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The invention creates a form of 'copying' the remote conditioning effect by transferring it through donor blood. Instead of directly applying the conditioning procedure to the treatment subject (which requires tissue bed access), the protective effects are copied and delivered via the transfused blood, bypassing the need for direct tissue access.

Inventive Principle:
Principle #26Copying

AI summary

Treatment methods are described using blood collected from a donor after subjecting thereof to remote conditioning such as remote ischemic conditioning via several episodes of short-term limb occlusion. Blood containing remote conditioning substances or a biologically active preparation containing such substances may be stored and used at a future time to afford a health benefit to the treatment subject. Extraction of remote conditioning substances may be done extracorporeally using dialysis or other blood processing methods following by returning of blood to the donor. Extraction of remote conditioning substances may be done during the time periods of their maximum presence in donor blood.
