Pressure Infusion TRIZ Cases
- Sterile Medicament Dispenser with Aseptic Connector
An integrated sterile assembly eliminates complex setup steps by routing medicament through a pre-filled reservoir and aseptic connector.
- Thermostatting Device for Medical Fluid Bags
A thermostatting device heats medical fluid bags via a conductive surface and retention means.
- Medical Injection Device Gas Evacuation Mechanism
A medical injection device uses a piston and selector to automatically evacuate gas from the inner space before dosing.
- Infusion Patch Anesthetic Reservoir for Continuous Pain Relief
An infusion patch integrates a detachable anesthetic reservoir with a skin-access conduit to deliver pain relief directly at the cannula site.
- Valve Seat Inclination for Stable Liquid Medicine Flow
An annular valve seat with an inward radial inclination contacts a disk-shaped valve body to stabilize liquid medicine delivery.
- IV Fluid Reservoir Pump with Pressure Valve
Reservoir pump automatically refills flushing fluid through a pressure-operated valve system, eliminating frequent syringe changes and sterilization.
- Adjustable Height Needle Infusion Device Intradermal Targeting
Rotating retraction dial and isolated needle hub maintain precise intradermal positioning against external forces.
- PCA Device Bolus Refill Prevention via Dual-Direction Clamp
A patient-controlled analgesia device uses a dual-direction clamp to segment fluid flow paths and prevent unintended bolus refill during drug delivery.
