Pharmaceutical Containers TRIZ Cases

Hinge columns in a waisted enteral bottle enable controlled collapse without air entry, maintaining sterility during emptying.

Nested chambers and collinear alignment resolve space constraints while maintaining a closed system to prevent contamination during reconstitution.

Segmenting the pump chamber with a rigid housing supports automated assembly handling while the deformable membrane displaces air during first use.

Identical blister cavities stack alternately to form a compact concertina, reducing landfill contamination from non-recyclable sachets.

A borosilicate glass composition with controlled oxide ratios maintains chemical durability and hydrolytic resistance.

Magnetic actuation deforms a flexible membrane to extract fractions without cap removal, preventing pathogen contamination during centrifugation.

A spring-loaded valve mechanism regulates fluid flow within a compact housing to enable secure attachment of medical waste collection bags.

A pivoting adapter links medical containers to dosing machine supports through integrated clipping mechanisms.

Merging connectors into a single body reduces manufacturing complexity while the movable portion maintains sealed hazardous drug transfer.

Segmented septum thickness resists inappropriate spikes, preventing fatal cross-over errors between intravenous and epidural fluids.

A segmented drug kit uses a sealing mechanism to connect and disconnect compartments for precise dose adjustment.

A collection liner self-assembles into a canister using pressure differences to inflate, preventing collapsed portions that reduce fluid intake capacity.

A vacuum source and actuator move hyperpolarized solution through a filter flow path without mechanical solenoids.
