Stretcher TRIZ Cases
- Articulating Joint Patient Handling Device for Positioning
Segmented support members with selectable articulating joints accommodate various patient postures without requiring multiple sling designs.
- Omni-directional Wheel Assembly for Patient Transport Maneuverability
A patient transport wheel assembly uses independent peripheral rotation to enable seamless directional changes without manual adjustments.
- Inflatable Transport Device With Release Valve
Segmented inflatable chambers with a release valve prevent over-expansion injuries caused by altitude changes and vibration.
- Auxiliary Wheel Speed Control for Patient Transport
A patient transport apparatus uses a throttle assembly to control auxiliary wheel speed via non-linear actuation.
- Three Coupled Quantum Well Optical Device Voltage Absorption
A three coupled quantum well structure reduces driving voltage through asymmetric layer thickness.
- Inductive Power System for Emergency Patient Cot
A wireless inductive power system recharges emergency patient cots using electromagnetic coils.
- Wheelchair Seat Division Mechanism with Synchronized Braking
A wheelchair seat divides into left and right portions via a link mechanism to create an entry opening.
- Adjustable Suspension System for Patient Transport Apparatus
A patient transport apparatus uses an adjustable suspension system to absorb energy from floor disturbances during movement.
- Patient Support Apparatus Drive Profiles for Maneuverability
A patient support apparatus uses a motorized auxiliary wheel assembly and drive profiles to control movement across various floor surfaces.
- Curved Tube Quick Release for Ambulance Stretchers
A curved tube actuates a quick release mechanism on an ambulance stretcher frame.
- Tool-Free Belt Locking Mechanism for Hygienic Patient Transport
Segmented metallic locking device enables tool-free belt detachment for rapid cleaning.
- Auxiliary Wheel Deployment for Patient Transport Control
Lift actuator deploys auxiliary wheel to improve control while reducing collision risk in congested areas.
- Stretcher Main Bars with Integrated Medical Storage
Hollow main bars incorporate compartments for medical instrumentation and drugs to consolidate equipment within the transport structure.
- Hydraulic Patient Cot Lift Assembly Tilt Control
Hydraulic actuators tilt the litter frame to speed ambulance loading while sensors maintain stability during rapid deployment.
- Track Drive Module for Emergency Stretcher
Elevating caster wheels with a mounting structure resolves the contradiction between smooth surface operation and uneven terrain reliability.
- Motorized Rescue Basket Transport with Alignment Slots
An electric motor rotates a single wheel to transport heavy loads, reducing user fatigue through automated propulsion and precise slot-based alignment.
- Wheelchair Linkage Mechanism for Bed Integration
A wheelchair drive link uses rollers sliding along rail portions to transform between chair and flat postures.
- Patient Support Side Ramp Pivot Mechanism
A patient support side ramp pivots to bridge the gap between floor and litter, eliminating strenuous manual lifting for emergency responders.
- Patient Support Unit Recesses for Device Mounting
Leg area recesses in support elements secure medical devices, resolving stability and space trade-offs.
- Power Lift Ramp With Magnetic Locks for Gurney Loading
Electric actuators position the ramp while magnetic locks hold the gurney, reducing operator strain on uneven terrain.
