Abstract
An attachment for a tracheal cannula that surrounds a cavity and is open in coupling and orifice areas, the attachment having in the coupling area a latching formation for the releasable connection to a mating latching formation of the tracheal cannula, the coupling area surrounding a section of the cavity, the section of the cavity surrounded by the coupling area being centrally penetrated by a virtual coupling axis, the coupling area having a support section, on which the latching formation and a force application area are situated the support section is displaceable between two positions of different radial distance of the latching formation situated on the support section from the coupling axis; the force application area and the latching formation displaceable by an exertion of force on the force application area of the same support section are situated along the coupling axis at an axial distance from each other.
Core Innovation
The invention relates to an attachment for a tracheal cannula that surrounds a cavity and provides access to the cavity. The attachment is open or openable both in a coupling area and in an orifice area, the orifice area being located differently than the coupling area. In the coupling area, the attachment surrounds a section of the cavity that is centrally penetrated by a virtual coupling axis.
In the coupling area, the attachment includes a latching formation designed for a releasable connection to a mating latching formation of the tracheal cannula. The latching formation is situated on at least one support section, and a force application area is positioned at a second location distinct from the first location. By exerting an actuating force on the force application area in a radial direction toward the virtual coupling axis, the at least one support section is displaceable between two positions with different radial distance of the latching formation from the virtual coupling axis.
The force application area and the latching formation displaceable by the exertion of force on the force application area of the same support section are situated along the virtual coupling axis at an axial distance from each other. The attachment is developed between the coupling area and the orifice area as a tube or a hood curved around an axis of curvature orthogonal to the virtual coupling axis, and mechanical implementation uses a support arm connected to a main component body that is tiltable around a tilting axis skewed with respect to the virtual coupling axis.
Claims Coverage
The document includes two independent claims. Across these claims, the inventive subject matter focuses on an openable tracheal-cannula attachment with releasable latching formations and an actuated support section/displacement concept with axial separation relative to a virtual coupling axis, including a skewed tilting-axis actuation relationship.
Attachment for a tracheal cannula with coupling and orifice openings and releasable latching
An attachment for a tracheal cannula surrounding a cavity and being open or openable both in a coupling area and in an orifice area, with a coupling-area latching formation releasably connectable to a mating latching formation of the tracheal cannula, the coupling area surrounding a section of the cavity centrally penetrated by a virtual coupling axis, and the attachment developed between the coupling area and the orifice area as a tube or a hood curved around an axis of curvature orthogonal to the virtual coupling axis.
Axially separated force application for radially displacing a latching formation about a virtual coupling axis
The coupling area has at least one support section with the latching formation at a first location and a force application area at a second location distinct from the first location, such that an actuating force on the force application area in a radial direction toward the virtual coupling axis displaces the at least one support section between two positions of different radial distance of the latching formation from the virtual coupling axis, wherein the force application area and the latching formation are situated along the virtual coupling axis at an axial distance from each other.
Skewed tilting axis producing oppositely directed effective displacements
At least one support section comprises a support arm connected to a main component body movable relative to the latter, tiltable around a tilting axis skewed with respect to the virtual coupling axis, wherein the extension direction of the tilting axis together with the extension direction of the virtual coupling axis encloses an angle in the range of 70° to 110°, and wherein the force application area and the latching formation are situated on different sides of the tilting axis on the same support section so that a radial actuation displacement of the force application area effects an oppositely directed effective displacement of the latching formation.
Together, the independent claims cover a tracheal-cannula attachment with open or openable coupling and orifice areas, releasable latching formations, and radial displacement of a support section and its latching formation with the force application area axially separated from the latching formation. The tiltable support arm feature further constrains actuation through a skewed tilting axis with a defined 70° to 110° angular relationship and an oppositely directed effective displacement relationship between the force application area and the latching formation.
Stated Advantages
Enables lower and controllable disconnection forces while reducing reactive stress to the patient.
Documented Applications
