摘要:
A seal and a mask using a seal that includes a first end portion adapted to be coupled to a seal support, a second end portion adapted for sealing engagement with a face of a user, and a sidewall extending between the first end portion and the second end portion. The first end portion, second end portion, sidewall, or any combination thereof is formed from an elastomeric material having an elongation of at least 1000%. The seal preferably formed from a unitary piece of elastomeric material.

A respiratory mask including a base plate adapted for connection to a gas source and a bladder secured to the base plate to form a generally fluid tight seal with the base plate, and defining at least one internal chamber with the base plate for receiving a fluidizing medium to fill the bladder and form a resilient cushion.
摘要:
A patient interface of the present invention includes a faceplate including a plurality of headgear attachment elements, a seal member operatively coupled to the faceplate; and an adjustment mechanism coupling the seal member to the faceplate. The adjustment mechanism controls the position of the seal member relative to the faceplate such that the seal member is moveable from a first position to a second position and is maintained in the second position during use of the patient interface after being moved to the second position.
摘要:
A patient interface having a forehead support adjustably. The forehead support assembly includes a support arm that is adjustably mounted to the mask shell, thereby allowing the adjustment of the distance between the forehead support bracket and the mask shell in order to adjust for patient's of different sizes. A forehead support bracket is pivotally connected to the support arm. The pivoting forehead support bracket is self-aligning to allow the forehead pad to remain parallel to the patient's forehead at all times, thus enhancing comfort and stability. The forehead support bracket is removable from the support arm, allowing the headgear (with support bracket attached) to be donned separately from the mask and support arm. The forehead support bracket in one embodiment has a forehead pad formed from the headgear itself.

The present invention provides a connection device for connecting a headgear having straps, a mask and a system for supplying a flow of gas to a patient. The connection device incorporates a locking member or locking portion which is configured to lock the straps in a particular location.
摘要:
A patient interface assembly for use with gas monitoring. The patient interface includes a mask shell having a portion that seals against the face of a patient and a mask attachment coupled to an opening of the shell. The mask attachment has a mask connection section coupled to the opening of the shell, an airway adapter section that serves as a gas measurement site for use in measuring a respiratory variable, and a breathing system connection section adapted to be coupled to a to a patient circuit. The gas measurement site, which includes a window, may be disposed on the conduit, the shell, or both. An access port, defined in the mask, the mask attachment, or both permits a sampling tube to be placed in fluid communication with an airway of a patient.
摘要:
Condensation management techniques for a gas flow delivery system. The techniques include providing a radiant barrier associated with patient circuit and/or a patient interface, providing a water trap and/or an absorbent insert in the patient interface device, or a combination of these techniques. The radiant barrier prevents condensation from forming in the patient circuit and/or the patient interface. The water trap and absorbent insert in the patient interface control condensation that reaches or forms in the interior of the patient interface to prevent it from interfering the user of the gas delivery system.

摘要:
A patient interface gas delivery mask having a forehead and chin support system including a forehead support, a chin support, and a system for supplying a flow of gas to a patient that incorporates such a mask, forehead support, and chin support. The forehead support includes a supporting arm which is adjustably mounted to the mask shell, thereby allowing the adjustment of the distance between the forehead support bracket and the mask shell in order to adjust for patient's of different sizes. A forehead support bracket is pivotally connected to the support arm. Likewise the chin support is also adjustably mounted to the mask shell.
摘要:
A forehead pad that includes a base member having a first side adapted to be coupled to a forehead support member. The pad also includes a patient contacting member having a first side adapted to contact a surface of a patient. A neck portion couples a second side of the base member and a second side of the first patient contacting member. The neck portion includes at least one cutout to allow at least a portion of the first patient contacting member to move relative to the base member so that the patient contacting portion of the pad is self-aligning with the surface of the patient even if the base member is not parallel with the surface of the patient.
