Tourniquets TRIZ Cases

Hidden spring-loaded axle sockets eliminate visible pivot pins, preventing skin injury and bacterial accumulation in venous tourniquets.

A spiked elastic tourniquet uses a tri-glide buckle to apply constrictive tension through an elastomeric body.

Pre-tensioning the stretchable wall on the support creates a convex shape that distributes pressure uniformly and eliminates creases.

A compression device uses a single-direction locking buckle and strap loop to apply circumferential pressure for blood flow occlusion.

A radial compression band integrates a Doppler probe to monitor arterial blood flow and dynamically adjust pressure during hemostasis.

An integrated garment tourniquet system applies pressure via a rotating tightening mechanism, reducing application time and blood loss during emergencies.

Anti-pinch plate prevents skin and fabric from twisting into the band, ensuring stable compression without focal tissue damage.

An inflatable vascular compression chamber applies controlled pressure to access sites while maintaining acoustic transparency for ultrasound imaging.

A disposable tourniquet cuff uses thin-film thermoplastic construction joined by radio frequency welding to create a flexible inflatable bladder.

Teeth on the buckle prevent strap disengagement while the windlass applies tensile force to restrict blood flow.

A hemorrhage control plate with a bulbous node applies direct pressure to major arteries for effective blood flow occlusion.

Segmented main body with a ductile second region resolves the contradiction between rigid support and limb adaptability.

A vascular ring with an inflatable inner chamber adjusts blood flow via a perforation and protrusion closure that releases under overpressure.

A non-pneumatic tourniquet uses a resiliently elastic body with multiple sized holes to accommodate various digit dimensions.

Sliding base plates on a circumferential strap allow adjustable pressure pads to target junctional wounds, preventing slippage during application.

A compressive cryo-hemostatic wristband accelerates hemostasis using a saline-filled reservoir pad.

A tourniquet uses a ratcheting control rod to pull and lock a tightening band securely.

An elastic tourniquet uses a separate adhesive strip to anchor the band around a limb, enabling self-constriction without skin contact.

A modular pelvic fixation device stabilizes the patient position while compressing great vessels to control hemorrhage.

A pliable wrap secures a solid block against the torso to apply controlled pressure.

A mobile torus device with variable diameter and transducer-controlled tension displaces blood along an extremity.

Self-aligning features reduce application time while maintaining reliable blood flow occlusion.

Segmented compression arms apply targeted pressure to carotid arteries, enabling independent operation without medical supervision.

A vascular closure device uses a three-dimensionally asymmetric force-transmitting surface to apply targeted pressure for rapid hemostasis.

A foldable injection portion integrates gas delivery into a hemostatic band, eliminating the need for separate dedicated instruments.

A vascular compression pad uses a ratchet strap to apply targeted pressure for hemostasis.

Thickened pressure means on a flexible strap resolves the trade-off between comfort and precise localized pressure application.
