Enemata/Irrigators TRIZ Cases
- Surgical Fluid Pump Control with Pressure Feedback
A surgical pump system uses peristaltic tubing and pressure feedback to regulate fluid flow.
- Nasal Administration Container Plunger Dosing Control
A nasal administration container regulates plunger travel via a detachable stopper to deliver precise medical fluid doses.
- Hanger Arm Extension Pump Cover for NPTWi
A hanger arm extension pump cover integrates protection and suspension functions into a single component.
- NPWT Controller Dynamic Fluid Volume Adjustment
A negative pressure wound therapy controller adjusts instillation fluid volume using a reduction factor derived from therapy duration.
- Preassembled Irrigation Pump with Permanently Fastened Reservoir
A preassembled irrigation pump permanently fastens a reservoir to an insertion member via a liquid tube for direct fluid delivery.
- Bubble Detection in Irrigation Fluid via Distal Temperature Monitoring
A distal temperature sensor monitors irrigation fluid to detect bubbles at the probe tip.
- Collet Workpiece Retention Mechanism for Oral Care Devices
A collet connection mechanism uses strain energy to lock and unlock oral care workpieces automatically.
- In-line Pressure Sensors for Stable Anterior Chamber IOP
In-line irrigation and aspiration sensors provide real-time pressure data to a controller during phacoemulsification surgery.
- Surgical Handpiece Connector Overmolded Seal
Overmolded elastomer ring eliminates user-installed O-rings by integrating sealing and locking functions, preventing irrigation fluid ingress.
- Medical Instrument Handle Sealing Adapter Design
A connection adapter uses dual ring grooves to roll an O-ring during insertion.
- Wound Care System With Dual Capillary Membranes
A wound dressing system uses two planar capillary membrane systems connected to supply lines for fluid delivery.
- Collapsible Reservoir With Segmented Hinged Steps
Segmented steps with external and internal hinges allow the reservoir to collapse fully without buckling or snapping back.
- Hydrophobic Membrane Valve for Ophthalmic Gas Venting
Segmented pathways with a hydrophobic filter prevent air bubbles in infusion lines while allowing safe back-flow of fluids.
- Emergency Stop for Anal Irrigation Catheter
Automated fluid delivery manages expansion and purging of the retention element to resolve manual control difficulties.
- Offset Cannula Suction Device for Laparoscopic Clogging
Segmented offset cannulae generate multiple suction pathways that prevent clogging during laparoscopic tissue removal.
- Spinal Disc Ablator Tool with Integrated Impedance Control
An RF ablator tool integrates a visualization scope and irrigation channels to clear debris during tissue removal.
