Respiratory mask

Abstract

A respiratory mask, a mould for a respiratory mask, as well as to a method for producing a respiratory mask are disclosed, in which manufacturability and usability of respiratory masks are improved. A respiratory mask is disclosed for administering a breathable gas to a patient, the respiratory mask comprising a first component formed from a flexible material and a second component formed from a material that is more rigid than the flexible material, wherein the first component is formed onto the second component by an overmoulding process.

1 . A respiratory mask for administering a breathable gas to a patient, the respiratory mask comprising:
 a first component formed from an elastomeric material; and   a second component formed from a material that is less flexible than the elastomeric material, wherein the first component is integrally formed onto the second component.   
     
     
         2 . The respiratory mask as claimed in  claim 1 , wherein the integral forming is such that the first component can be manually separated from the second component. 
     
     
         3 . The respiratory mask as claimed in  claim 1 , wherein the integral forming is such that the first component is joined to the second component in an intimately adhering manner. 
     
     
         4 . The respiratory mask as claimed in  claim 1 , wherein the integral forming is carried out in an injection moulding tool. 
     
     
         5 . The respiratory mask as claimed in  claim 1 , wherein the elastomeric material is an LSR material. 
     
     
         6 . The respiratory mask as claimed in  claim 1 , wherein the second component is formed from a polycarbonate material. 
     
     
         7 . The respiratory mask as claimed in  claim 1 , wherein the first component is a sealing cushion. 
     
     
         8 . The respiratory mask as claimed in  claim 1 , wherein the first component is an outlet conduit device. 
     
     
         9 . The respiratory mask as claimed in  claim 1 , wherein the first component is a forehead-contacting device. 
     
     
         10 . The respiratory mask as claimed in  claim 1 , wherein the first component is a closure device. 
     
     
         11 . The respiratory mask as claimed in  claim 1 , wherein the first component is an articulated structure. 
     
     
         12 . The respiratory mask as claimed in  claim 1 , wherein the first component is a diaphragm device. 
     
     
         13 . The respiratory mask as claimed in  claim 1 , wherein the first component is a tubular body portion. 
     
     
         14 . The respiratory mask as claimed in  claim 1 , wherein the first component is a breathing gas line segment. 
     
     
         15 . The respiratory mask as claimed in  claim 1 , wherein the first component is a functional seal. 
     
     
         16 . The respiratory mask as claimed in  claim 1 , wherein the first component is a stop device. 
     
     
         17 . The respiratory mask as claimed in  claim 1 , wherein the first component is a decoration or logo. 
     
     
         18 . The respiratory mask as claimed in  claim 1 , wherein the first component is a headband connection device. 
     
     
         19 . The respiratory mask as claimed in  claim 15  wherein the first component is a soft gripping pad. 
     
     
         20 . The respiratory mask as claimed in  claim 15  wherein the second component is a forehead rest mount.
