Respiratory device comprising a fastening system
The invention relates to a device for respiration which consists at least of one body that delimits an inner chamber from an outer chamber, a region for sealing the device against parts of the face of a patient, fastening elements for positioning the device on the patient's head and a connection for supplying respiratory gas. The device is equipped with an actuator, which when adjusted, changes the distance of at least one part of the device from at least one part of the body of the patient.
1. A breathing device, wherein the breathing device comprises a body which delimits an internal space from an external area; an area for sealing the device relative to facial areas of a patient; fastening elements for positioning the device to a head of the patient; a connection for supply of breathing gas; a forehead rest for supporting the breathing device at the head of the patient; an adjusting member which is an actuating element of the forehead rest and which, when being adjusted, is adapted to change a distance of at least one part of the device to at least one facial area of the patient, the forehead rest being movable not proportional to a movement of the adjusting member at least in portions of an adjusting range, adjustment taking place through movement of the adjusting member which engages through a stationary forehead rest shaft and includes guide elements which engage in curved guide grooves in a forehead rest support arm connected to the forehead rest and move the forehead rest support arm during the adjustment, the forehead rest support arm being slotted in a lower area thereof and having locking elements at ends of both sides thereof, which locking elements engage in corresponding openings in the forehead rest shaft.
2. The breathing device of claim 1 , wherein in side view the forehead rest support arm is curved in S-shape.
3. The breathing device of claim 1 , wherein transmission of movement of the adjusting member to the forehead rest takes place in a middle adjusting area of the adjusting member with a greater or smaller transmission factor than in at least one border area of the adjusting range of the adjusting member.
4. The breathing device of claim 1 , wherein the device further comprises at least one of an optical, acoustic or tactile marking of an adjusted position of the forehead rest or the adjusting member.
5. The breathing device of claim 1 , wherein a special adjusting position or a special adjusting area of the forehead rest is emphasized at least one of optically, acoustically or by tactile elements.
6. The breathing device of claim 1 , wherein several positions or position areas in an adjusting portion of the forehead rest are emphasized at least one of optically, acoustically or by tactile elements.
7. The breathing device of claim 1 , wherein the adjusting member carries out an essentially rotatory movement during adjustment.
8. A breathing device, wherein the breathing device comprises a body which delimits an internal space from an external area; an area for sealing the device relative to facial areas of a patient; fastening elements for positioning the device to a head of the patient; a connection for supply of breathing gas; a forehead rest for supporting the breathing device at the head of the patient; an adjusting member which is an actuating element of the forehead rest and which, when being adjusted, is adapted to change a distance of at least one part of the device to at least one facial area of the patient, the forehead rest being movable not proportional to a movement of the adjusting member at least in portions of an adjusting range, adjustment taking place through movement of the adjusting member which engages through a stationary forehead rest shaft and includes guide elements which engage in curved guide grooves in a forehead rest support arm connected to the forehead rest and move the forehead rest support arm during the adjustment, the forehead rest shaft and the forehead rest support arm being connected through two holding elements which are arranged on the forehead rest support arm and are rotatably supported in the forehead rest shaft.
9. The breathing device of claim 8 , wherein the holding elements are pins.
10. The breathing device of claim 8 , wherein in side view the forehead rest support arm is curved in S-shape.
11. The breathing device of claim 8 , wherein transmission of movement of the adjusting member to the forehead rest takes place in a middle adjusting area of the adjusting member with a greater or smaller transmission factor than in at least one border area of the adjusting range of the adjusting member.
12. The breathing device of claim 8 , wherein the device further comprises at least one of an optical, acoustic or tactile marking of an adjusted position of the forehead rest or the adjusting member.
13. The breathing device of claim 8 , wherein a special adjusting position or a special adjusting area of the forehead rest is emphasized at least one of optically, acoustically or by tactile elements.
14. The breathing device of claim 8 , wherein several positions or position areas in an adjusting portion of the forehead rest are emphasized at least one of optically, acoustically or by tactile elements.
15. The breathing device of claim 8 , wherein the adjusting member carries out an essentially rotatory movement during adjustment.
