Laryngeal Mask Ventilation Device With Head Harness and Pusher Mechanism
Summary
The USPTO published patent application US20260108373A1 for LMA OPTIMIZER B.V., filed January 9, 2024 under Application No. 19146174. The invention covers a ventilation assembly comprising a head-wearable harness and a pusher mechanism designed to press against the floor of a subject's mouth during laryngeal mask ventilation, with laterally opposite protrusions to displace soft tissue at the submandibular triangles. The pusher or each protrusion is hollow, providing a recess for accommodating an operator's finger. CPC classifications include A61F 5/05891, A61M 16/0447, and A61M 2205/42.
“A ventilation assembly (37) for use in ventilation of a subject using a laryngeal mask (5) comprises a head-wearable harness (39) and a pusher (41).”
About this source
USPTO classification A61M covers devices that introduce or withdraw fluids from the body: infusion pumps, catheters, syringes, inhalers, wound drainage, dialysis equipment, and fluid-handling microfluidics. Every newly published application in A61M lands in this feed, around 205 a month. Applications publish 18 months after filing. Watch this if you compete in infusion therapy or drug delivery, file freedom-to-operate analyses for medical device startups, scout acquisition targets in cardiovascular or respiratory devices, or track hospital R&D arms that are quietly patenting clinical innovations.
What changed
The USPTO published a new patent application (US20260108373A1) for LMA OPTIMIZER B.V. disclosing a ventilation assembly with a head-wearable harness and a pusher mechanism. The harness is designed to be placed on a patient's head to support the pusher, which presses against the floor of the mouth and uses laterally opposite protrusions to displace soft tissue at the left and right submandibular triangles in a cranial direction relative to the mandible. Each protrusion or the pusher as a whole is hollow, providing a recess for accommodating an operator's finger. The invention is classified under CPC codes A61F 5/05891, A61M 16/0447, and A61M 2205/42.
Medical device manufacturers developing airway management or ventilation assistance products should review this filing to assess potential overlap with their own intellectual property portfolios. Competitors in the laryngeal mask or supraglottic airway device space may wish to monitor the prosecution of this application for claim scope and potential design-around opportunities.

Abstract
A ventilation assembly (37) for use in ventilation of a subject using a laryngeal mask (5) comprises a head-wearable harness (39) and a pusher (41). The harness is arrangeable on the subject's head (H) for supporting the pusher to press against the floor of the mouth (15) of the subject (P). The pusher comprises laterally opposite protrusions to displace, in use and operably supported by the harness on the subject (P), soft tissue of the subject at the left and right submandibular triangles (trigonum submandibulare) in cranial direction relative to the mandible (29) of the subject and surrounding tissue of the subject such as the submental triangle (trigonum submentale) for, when the laryngeal mask is installed in the airway of the subject, urging internal soft tissue of the subject against the laryngeal mask in the airway of the subject. Each protrusion or the pusher as a whole is hollow providing a recess for accommodating an operators' finger.
