Infusion Syringes TRIZ Cases

A resilient member blocks battery contact during storage and powers the cap electronics only after removal, cutting standby drain and enabling reliable use detection.

Pinch-actuated boot engagement helps users remove an obscured needle boot with less grip force, improving injection device readiness.

Electromagnetic illumination and image analysis verify syringe fill status, detect air bubbles, and identify fluid type from a distance.

A double-chamber syringe balances air pressure during closed medicine transfer to reduce leakage risk with a simpler, lower-cost sealing structure.

A sealed dual-cap with antimicrobial pads enables short- and long-term disinfection while preventing alcohol evaporation and connector damage.

A pressure-driven floating stopper and bi-stable septum let one syringe deliver medication and flush solution while reducing catheter occlusion risk.

Barcode scans, weight sensors, and cameras verify IV medication compounding while a central server assigns tasks to reduce errors, waste, and delays.

A flat syringe scale and portable imaging verify low-dose fills, improve visibility of clear fluids, and help prevent needlestick risk.

A reusable drive paired with disposable reservoir modules supports different injection volumes while cutting waste and redesign cost.

Optical sensor arrays track movable and rotating pen elements to determine dialled dose accurately without complex camera-based monitoring.

Friction-induced sound and vibration signals are captured during syringe ejection to verify dose delivery, improve safety, and prevent unintended reuse.

A groove-trapped locking element lets the cap unscrew while leaving clear tamper evidence to protect syringe sterility and contents integrity.

A threaded sleeve moves from injection to shielding to locked positions, cutting syringe parts while preventing needle reuse and infection.

A forward plunger tip cuts syringe dead space and anchors an annular seal to support needle retraction without leakage or needle stick risk.

A flexible needle and angled orientation structure guide injections around vessels and nerves for precise deep-target delivery with less tissue damage.

Flexible arm protrusions apply pressure around the injection site to distract sensation and reduce subjective pain during drug delivery.

A self-assembling collagen slurry enables needle delivery in confined synovial joints while supporting fibrin clot formation for tissue repair.

Segmented guide grooves remove gas while screw-coupled plunger drive improves fixed-dose injection accuracy, safety, and wearability.

A self-assembling collagen slurry helps repair meniscus and ligament tissue in synovial joints where synovial fluid disrupts fibrin clot healing.

COP or COC syringe barrels block EtO ingress during sterilization, keeping prefilled drug pH within USP range and residue limits.

A retractable shield, lock-out, and actuator cover prevent accidental needle sticks and unintended actuation during handling and disposal.

A gellan gum gel forms a 3D injectable network that maintains tissue lift longer during resection and reduces repeat injections.

A pre-attached disinfecting cap and lock syringe simplify SASH catheter care, maintain sterility, and help prevent blood reflux.

A sealed cup-cap syringe tip assembly with peelable seal and absorbent swab simplifies VAD disinfection while reducing contamination risk.

A shrink film label locks the syringe adaptor against rotation, adds tamper evidence, and carries RFID without cap torque issues.

A self-assembled collagen implant avoids cross-linking agents to support suture fixation, tissue regeneration, and lower foreign body reaction.

An actuatable hemostasis valve and deformable seal help an introducer sheath limit blood leakage while keeping vascular access compact and easier to use.

A centred membrane valve, hydrophobic sealing, and force sensing prevent leaks, balance pressure, and keep infusion dosing accurate.

Notches and recessed valve faces guide uniform inward buckling to prevent fluid deposition, leakage, and slow valve recovery.

A controlled acid acceptor surface area and loading keeps drug pH stable while limiting halogen-gas corrosion in medical rubber products.

Joint movement lets a medical device and mobile device derive matching keys, securing Bluetooth data without NFC.

A deformable cushion and contoured cutout spread insertion stress across the injector tip, reducing plunger damage during intraocular lens delivery.

Compressed air keeps the optical sensing zone clear of water and mist, enabling accurate silicone coating inspection in production.

A pivoting plunger rod folds alongside the syringe barrel to cut pre-filled syringe footprint while preserving sterility and easy deployment.

Sliding depth guides and detents set precise injection depth while the integrated guard helps prevent needle sticks after use.

A flat barrel with a width greater than its thickness enables injections as low as 2.5 degrees while reducing interference at the injection site.

Bitterness suppressants such as sugars, acids, and amino acids help dental anesthetic solutions reduce aftertaste while preserving pain control.
