Jet Injection Syringes TRIZ Cases

Processor-based temperature monitoring records storage conditions, compares them with preset ranges, and alerts users when medications face excursion risk.

Laser heating replaces complex ejector structures to precisely atomize high-viscosity liquids with strong spray output and simpler design.

A distributor chamber connects radially offset wound therapy lumens without precise alignment while preventing unwanted fluid exchange.

A capacitive sensor verifies contact with a large bare skin area before needle movement, preventing accidental expulsion and needle injury.

Direct fluid pressure and separate pistons remove energy accumulators, reducing wear and user-caused variation in needle-free injections.

Artificial tissue cavities are filled in situ with biodegradable polymer to form microimplant arrays for sustained drug or live cell delivery.

A removable blocking ring prevents accidental injector firing, while a needle guard and lockout stop needle exposure and unintended reuse.

A weakened plunger section deforms under overload to absorb ejection energy and protect the injector housing from excessive force.

Heterogeneous hydrophobic and hydrophilic chamber patches control the meniscus to stabilize jet ejection and reduce splash-back in skin delivery.

Compressed air drives and resets a hammer-piston jet injector, enabling stable repeated drug delivery with lower mechanism complexity.

A spindle retainer and automatic cassette ejection mechanism prevent reset failures and reduce contamination from handling used cassettes.

Pre-connected sensor carriers and locating pins secure electrical alignment during assembly, improving continuous glucose monitoring comfort and reliability.

A helical ramp, roller, and movable spacer shorten plunger stroke for precise fluid dosing while limiting motor stress in portable injection systems.

Gas-driven staged pressing enables continuous fixed-dose needleless injection without repeated ampoule replacement or spring compression.

An adapter tube and built-in touch control stabilize gas delivery, reduce turbulence and space, and improve needle-free injection use.

Adjustable spray heads and pressure-stable tubing improve intranasal livestock dosing accuracy while reducing operator fatigue and error.

Lockout clips and dual dose retention prevent cassette re-use and premature solid dose release in needle-free delivery.

Branched inner-chamber flow paths let one pressure source drive dense multi-nozzle drug delivery with precise formation and shorter treatment time.

A motor-driven ramp, roller, and freewheel coupling enable lightweight one-handed needle-free injection with precise dosing and lower mechanical stress.

A working-fluid jet opens a tissue channel and reaccelerates the cell stream, reducing shear stress, leakage, and tissue trauma.

Automatic cassette ejection and a spindle retainer prevent re-setting failures and reduce contamination in reusable needle-free drug delivery.

Electrically triggered pyrotechnic charges enable a thin wearable patch to deliver multiple timed needle-free injections without repeated clinic visits.

Varying magnetic properties along the actuator stroke shape injection force over time, improving depth and volume control without complex circuits.

A modular dual-chamber BFS vial enables sterile single-use vaccine reconstitution while avoiding reusable syringes and separate sterilization.

A detachable needle seat and outer sleeve let only the contaminated needle assembly be discarded while the barrel supports needle-free dosing.

A movable chamber body meters powdered hemostatic agent with fluid flow to prevent clogging and improve dosing at deep GI treatment sites.

A floating trigger with axial rotation cuts firing force and accidental discharge risk in needle-assisted self-injectors.

A staged rotary motor and linear actuator create a skin-piercing injectate jet, enabling precise needle-free subcutaneous drug delivery.

Combustion-driven pressurization enables 75-150 m/s biomolecule injection for direct cell nucleus delivery across diverse targets.

A weakened plunger section deforms under excess pressurization force to protect the injector housing and keep needleless injection safe.

A button-actuated pressure source and catheter enable localized powder or fluid delivery while reducing healthy tissue exposure and clogging.

Measured cartridge and nozzle features are encoded on tags so injection force and velocity can compensate for manufacturing variation.

A movable chamber body meters powder, blocks unwanted fluid entry, and reduces clogging for consistent endoscopic delivery deep in the GI tract.

A tubular metal insert inside a resin injector body resists igniter pressure while keeping the needleless injector compact and lightweight.
