Description

The respiratory therapy face shield

Technical field

The present invention is about a kind of face shield, espespecially a kind of respiratory therapy face shield, it can connect the air tube of a breathing equipment, and can make air tube carry out universal rotational, no matter make the patient with respect to which position of breathing equipment, air tube all can turn to suitable direction, avoids the air tube overflexing and causes gas to be supplied with having some setbacks, even to cause the problem that causes inward mask leakage because pullling.

Background technology

The respiratory therapy face shield is that a kind of sufferer head that is worn on connects a breathing equipment for sufferer, the use of breathing by breathing equipment.The U.S. discloses No. 2009/0044808 patent application case and discloses a kind of respiratory therapy face shield, it has a cover body and a headband, this face shield body is arranged at the nose place of sufferer, and the face shield body be provided with two nasal tubes in case respectively against and slightly stretch into the nostril and guarantee that oxygen can be transported in the sufferer nasal cavity, this outer mask body can connect the air tube of a breathing equipment, so that breathing equipment energy delivering oxygen is in the sufferer nasal cavity.This headband is arranged on the face shield body, can restraint in the sufferer head, guarantees that the face shield body can be fixed in sufferer nose place really.

Yet, only be fixed with general fixed form between above-mentioned face shield body and air tube, and can't rotate for air tube opposite face cover body.When the relative position of breathing equipment and sufferer changes, air tube must bend in different directions, cause the air tube inner passage to narrow down and affect the flow velocity of oxygen delivery if bending degree is excessive, even air tube too crooked and easily and breathing equipment be separated from each other, or break away from the face shield body is unexpected, cause treatment to be interrupted and jeopardize sufferer life.
