Specific implementation mode
To facilitate the understanding of the present invention, with reference to embodiment to invention is more fully described.Although giving The preferred embodiment of the present invention.But the present invention can realize in many different forms, however it is not limited to described herein Embodiment.It is made the disclosure of the present invention more thorough and comprehensive on the contrary, purpose of providing these embodiments is.
Referring to Fig. 1, the present invention provides a kind of breathing mask, including mask body 1 and it is connected with the mask body 1 For to the mask body 1 convey gas admission line 2.The mask body 1 includes air admission hole 11 and gas vent 12, The air admission hole 11 is connected with the admission line 2.The breathing mask further includes being set to leading in the mask body 1 To pipe 3 and the gas deflation assembly being set in the mask body 1.One end of the guide pipe 3 by the air admission hole 11 with The admission line 2 is connected, and the other end of the guide pipe 3 is tilted towards the direction close to 1 top of the mask body to be extended And equipped with opening.The gas deflation assembly include pressure acquisition unit 41, pressure sensitive unit 42, controller 43, exhaust pipe 44 with And it is set to the exhaust modulation device in the exhaust pipe 44.One end of the pressure acquisition unit 41 connects the mask body 1 outside wall surface, the other end of the pressure acquisition unit 41 are connected with the pressure sensitive unit 42.The controller 43 is distinguished It is connected with the pressure sensitive unit 42, exhaust modulation device.The exhaust pipe 44 is connected with the gas vent 12.
Through the continuous positive pressure fresh air in admission line input breathing mask, since the opening of guide pipe is towards respiratory surface The top of cover, and its inclined design make fresh air flow into more smooth with inside cycle, and make into breathing mask Air-flow forms top-down circulating current, and the carbon dioxide of exhalation is avoided to be stranded in the top of breathing mask when user exhales Portion effectively avoids the repetition of carbon dioxide from sucking.
Controller receives pressure sensitive unit signal determining user breathing and replaces signal, when the wearer inhales the air, control Device controls exhaust modulation device and reduces exhaust pipe sectional area, reduces air leakage, while increasing breathing mask internal pressure, auxiliary makes User sucks live gas;When the wearer exhales the air, controller control exhaust modulation device expands exhaust pipe sectional area, increases leakage To reduce respiratory surface internal mask pressure breathing mask directly is discharged through gas vent and exhaust pipe in user's exhaled gas by tolerance Outside.To by the design of exhaust modulation device, on the basis for having used the gas vent than conventional breathing mask aperture bigger On, the intelligent control to leaving area is realized, has both reduced the waste that power consumption in turn avoids air source gas, while can also be more Auxiliary user breathing well, is also compatible with the user of matching different tidal volumes.Moreover, the design of exhaust modulation device is led with aforementioned The design of skirt is combined, and further improves the overall effect of breathing mask.
Referring to Fig. 2, one end closing of the exhaust pipe 44, another end opening are simultaneously connected with the gas vent 12, institute The tube wall for stating exhaust pipe 44 is equipped with active leakage hole 55, and the active leakage hole 55 is located at outside the mask body 1.The row Gas control device includes block piece 54, connects the elastic stretching part 53 of the block piece 54 and controllable 54 grams of the block piece The stretching control assembly for taking the pulling force of the elastic stretching part 53 and being moved along the direction of the parallel exhaust pipe central axes, it is described The leaving area of active leakage hole 55 changes with the movement of block piece 54.
In the present embodiment, the control assembly that stretches includes that the electromagnetic coil of one end setting is closed close to the exhaust pipe 44 It 51 and closes one end close to the exhaust pipe 44 and around the electromagnetic coil 51 and is set to the tube wall of the exhaust pipe 44 The annular magnetic ironware 52 of internal face.
When there is electric current to be passed through electromagnetic coil 51, with the increase of electric current, electromagnetic coil 51 drives block piece 54, overcomes bullet Property tensioning member 53 effect movement, the gas leakage area of masking active leakage hole 55, with the change of electric current, the adjustment master of block piece 54 The capacity size of dynamic leakage hole 55.
Specifically, the annular magnetic ironware is annular permanent magnet.
Specifically, the block piece is columned blocking sliding block.Because it is columned blocking sliding block and exhaust pipe it is interior Wall surface Curvature Matching degree higher, occlusion effect is more preferable, also more accurate to the adjustment of capacity.
Specifically, the elastic stretching part is extension spring.
In the present embodiment, the diameter of the gas vent 12 is identical as the diameter of the exhaust pipe 44, is 5-15mm.By This, the user that can match different tidal volumes uses, while taking into account cost and power consumption.
The present invention also provides a kind of respiratory assistance apparatus comprising breathing mask as described above.To Respiration assistance Equipment can realize the intelligence adjusting to capacity, expand the use function of equipment, promote the using effect of user.
More specifically, the respiratory assistance apparatus further includes host, and the host is equipped with processor, and the controller is Processor.The processor conduct for using due to the collocation of breathing mask and the host of Respiration assistance, therefore host directly being used to be equipped with The controller of exhaust modulation device not only contributes to save cost, also helps the stability and accuracy of control.
Example the above is only the implementation of the present invention is not intended to limit the scope of the invention, every to utilize this hair Equivalent structure or equivalent flow shift made by bright specification and accompanying drawing content is applied directly or indirectly in other relevant skills Art field, is included within the scope of the present invention.
