摘要:
A patient interface includes a cushioning structure including at least one hollow chamber filled with first and second discrete and/or layered filling materials and a seal forming structure formed in one piece with the cushioning structure. The seal forming structure includes a thin membrane flap that is structured to provide a seal to the patient's face. The chamber extends only around a portion of the perimeter of the cushioning structure such that the chamber with first and second filling materials is provided in cheek and lip regions of the cushioning structure and a solid silicone portion is provided in a nasal bridge region of the cushioning structure.

The present invention relates to a velcro inserting type universal synthetic resin mask with a replaceable filter, an injection molding apparatus therefor, and a manufacturing method thereof. The velcro inserting type universal synthetic resin mask with a replaceable filter according to an embodiment of the present invention comprises: a mask guide with a rim-like shape which supports a filter insertion portion therein and is formed of a synthetic resin by an injection molding process using an upper mold and a lower mold along with the filter insertion portion; and a velcro for attachment of a filter which is placed at a front portion of a velcro entity for attachment of a filter forming portion of the upper mold during 10 the injection molding process for the mask guide and the filter insertion portion and formed on the mask guide when inserted such that the velcro for attachment of a filter is fixed through a velcro entity insertion hole of the upper mold. According to the present invention, manufacturing time can by greatly reduced by using a one-stop injection molding using molds, and hygienic 15 conditions can be improved by replacing filters.

The invention relates to a method for producing a hollow structure and particularly a method for producing a closed and filled hollow structure. Furthermore, the present invention relates to a hollow structure and preferably a closed and filled hollow structure obtainable by a method according to the present invention as well as to a tool for producing such hollow structure and/or for performing a respective method. More particularly, the hollow structure according to the present invention as well as the filling is at least partially flexible and/or can be brought into a flexible condition. The method for producing a filled hollow structure comprises the steps: producing an open hollow structure of a first material; positioning the open hollow structure on a tool for holding the open hollow structure; filling the open hollow structure with a filler medium; closing the filled open hollow structure by means of clamping jaws providing a cavity; and filling the cavity with a second material for closing the open hollow structure.

Die Erfindung betrifft eine Atemmaske mit einem Maskenkörper (12) und einer Dichtkisseneinrichtung (1), die aus einem elastomeren Material gebildet ist und im Zusammenspiel mit dem Maskenkörper (12) einen Maskeninnenraum begrenzt und einer Auslaßeinrichtung zur Ableitung von zumindest teilweise verbrauchtem Atemgas aus dem Maskeninnenraum, wobei die Auslaßeinrichtung einen Strömungswegabschnitt (67,68,69,70;73,72) aufweist, der zumindest teilweise durch die Dichtkisseneinrichturig (1) definiert ist
摘要:
A viral barrier composite of a thermoplastic film (24) thermally bonded on at least one side thereof to a breathable thermoplastic web (22), and method for making the same. The viral barrier composite has viral barrier properties, a moisture vapor transmission rate of at least 700 g/m2/24 hours and a bond strength between the thermoplastic film breathable thermoplastic web of at least 0.07 N/cm. The viral barrier composite is formed by calendering an assembly comprising a thermoplastic film (24) and a breathable thermoplastic web (22) between a smooth roll (28) and a pattern roll (26). The viral barrier composite may be used for constructing articles of protective apparel.
