Anaesthesia TRIZ Cases

Vacuum suction pulls aerosols through a filter to prevent microorganism dispersion in operating rooms.

A medical cooling device sprays coolant from a reservoir through a spraying unit and valve to regulate flow toward a target region.

A trocar sleeve uses a diffusion polymer to absorb and release local anesthetic through apertures along the wound tract.

Trocar establishes a peritoneal reference plane to locate nerve blocks without ultrasound complexity.

A laser-based nutational infrasonic system liquefies and removes fat cells through a minimally invasive biopsy punch access.

Acoustic shock waves modulate adrenergic receptors to reduce opioid addiction risk by stimulating stem cell recruitment and reducing inflammation.

Segmented vermillion border injections deliver precise anesthetic volumes to numb lip tissue, avoiding anatomical distortion and prolonged facial numbness.

A handheld cooling probe anesthetizes targeted skin areas using a refrigerated surface to numb injection sites.

A cyclone nozzle directs refrigerant gas onto tissue for rapid local anesthesia, preventing cold burns through precise temperature control.

A medical cooling device thermally couples a lubricating member to an ocular surface for rapid anesthesia.

A pressure-activated heat patch releases vasodilators and anesthetics to facilitate intravenous access.

Flexible hollow skirt creates fluid-tight gingival seal, reducing patient trauma during intraligamentary injection.

An expandable device exerts pressure on mammalian tissue to displace it from an undistorted position, enabling measurement of mechanical response.

A thermal exchange module cools circulated fluid to regulate patient blood temperature during extracorporeal treatment.

A rotating cannula within a placement guide reduces tissue bruising and improves ease of operation during implant insertion.

Segmented flexible membranes bulge under pressure to deliver anesthesia simultaneously, reducing invasiveness compared to hypodermic needles.

Gravity-driven siphon transfers priming fluid from the blood reservoir to a separate collection bag, preventing hemodilution during extracorporeal circulation.

Integrated nerve block catheter employs a tissue lock and decoupler to maintain stable positioning at the target nerve while preventing medication backflow.

Integrated biopsy needle delivers intraosseous anesthetic through the central conduit to align the drilling site, reducing radiation exposure from CT guidance.

Segmented catheter with side holes provides complete urethral anesthesia, reducing patient discomfort and procedure time.

Echogenic needle coatings enhance acoustic impedance to reflect ultrasound waves, preventing catheter misplacement during nerve block procedures.

Inclined bite block with sliding support plate positions needle guide along mandibular axis.

A balloon catheter with a slidable camera enables precise sinus ostium dilation without radioscopic imaging.

Gravity-driven applicators deposit anesthetic on the hiatus to reduce postoperative pain and medication needs during hiatal hernia repair.

An injection needle uses an oblique cutting edge formed by opposing primary and secondary bevels to enhance structural rigidity.

A collapsible sleeve intraosseous tack device penetrates alveolar bone to deliver local anesthesia directly into cancellous bone.

Thin-film insulation separates electrodes in a multipolar cannula, reducing cross-section while maintaining electrical reliability.

A subdermal catheter device delivers anesthetic to autonomic nerve structures through a minimally invasive pathway.

A nebulizer valve forms a colloidal mixture of liquid cooling medium and propellant gas before delivery to the nozzle.

Segmented arterial catheters deliver targeted cooling and cerebrospinal fluid drainage, resolving systemic side effects from whole-body hypothermia.
