Dead Animal Preservation TRIZ Cases

Sodium pentaborate pentahydrate reduces dimethyl sulfoxide toxicity while maintaining ice crystal protection.

Coffee extract accelerates water supercooling to prevent ice crystal formation and necrosis, maintaining cell viability without complex apparatus.

A low molecular weight oligosaccharide composition protects biological samples during freezing.

Prepared porcine hearts simulate human cardiac function using inflatable balloons to replicate ventricular pressure dynamics.

Itaconate-based preservation solutions extend donor heart storage time by reducing ischemic damage and oxidative stress.

APEX anticoagulant composition extends whole blood shelf life to five weeks while maintaining coagulation activity.

Pivoting clamp members distribute force evenly and prevent unintended opening, resolving uneven pressure risks during perfusion procedures.

Controlled phase transitions in cryopreservation maintain cell viability, enabling tunable therapeutic agent delivery.

A preservation fluid combines dimethyl sulfoxide and acetic acid to maintain cadaveric tissue realism without refrigeration.

An isolated heart-lung preparation preserves four-chamber pumping activity to support medical device evaluation.

Vibrating cartilage with resonant acoustic energy accelerates cryoprotectant penetration during tissue processing.
