Estimating the term…
The invention concerns a gel covering of a patient interface. This gel covering has a mask connection area by which its side that faces away from the patient is joined with a mask body. The patient interface can be designed, for example, as a respiratory mask. On its side that faces the patient's face, the respiratory mask has thin, inwardly formed, peripheral contact lips. The respiratory mask has accessories that allow it to be fastened on the patient's head as well as a hose connection for supplying air. At least one region formed from a filler is placed in or on the walls of the gel covering. The method is used to produce the gel covering of the invention.
A method for producing a patient interface that contains a gel filling, wherein a gel covering (3) formed from a flexible material has a cavity (9) at least in some areas and has at least one opening, through which the cavity is filled with gel (15) in liquid form, which then cures in the gel covering.
A method for producing a sealed covering (3) for a patient interface, where a covering blank is sealed by a stopper, and a permanent connection between the covering blank and the stopper is produced by the use of joining means, wherein the sealed covering is produced from a uniform material.
A method for producing a covering blank for a patient interface, wherein the geometry of the covering blank is predetermined in the production process by at least one metal core, and after the covering blank has been produced, the metal core is removed through an opening in the covering blank, where the length of the opening is less than half the circumference of the covering blank.
A method for producing a patient interface that contains a gel filling, wherein a gel body is coupled with a base element by a two-component connection.
A patient interface with a gel filling, wherein one embodiment is realized as a nasal pillow.
A patient interface with a gel filling, wherein the cavity that holds the gel filling is sealed by at least one stopper that is vulcanized in.
A patient interface with a gel filling, wherein a gel covering (3) formed from a flexible material at least partially bounds a cavity (9), where the gel covering (3) has a sealed opening (10), through which the cavity (9) is filled with the gel in liquid form.
