Embodiment
The core of the present invention is to provide a kind of noninvasive breathing mask, to improve the safety in utilization of lung ventilator.The present invention'sAnother core, which is to provide, a kind of includes the lung ventilator of above-mentioned noninvasive breathing mask.
In order that those skilled in the art more fully understands technical scheme, below in conjunction with the accompanying drawings and embodiment partyThe present invention is described in further detail for formula.
Fig. 1 to Fig. 9 is refer to, in a kind of embodiment, the noninvasive respiratory surface that the specific embodiment of the invention is providedCover includes mask body 1 and the air inlet 2 being arranged in mask body 1 and gas outlet 3, it is preferable that air inlet 2 is located at mask body1 top.The regulating valve 5 for adjusting the size of gas outlet 3 is set in mask body 1.Specifically, regulating valve 5 can be for slidablyThe plugging plate of the end of gas outlet 3 is arranged on, plugging plate is slided as needed, the regulation openings of sizes of gas outlet 3 can give mask sheetDifferent malleation in body 1；When regulating valve 5 is by gas outlet contract fully, the NIV masks controlled entirely available for lung ventilator.
When patient uses lung ventilator, gas is entered inside mask body 1 by the air inlet 2 of mask body 1, by going outGas port 3 is discharged.
By foregoing description, in invention provides the noninvasive breathing mask that specific embodiment is provided, according to patientActual demand, operator's operation regulating valve 5 realizes the size control of gas outlet 3, and then realizes that the internal pressure of mask body 1 is adjusted,Therefore, the noninvasive breathing mask that the application is provided is effectively improved the safety in utilization of lung ventilator.
Specifically, the noninvasive breathing mask can be used for the NIV masks that CPAP masks are controlled entirely with lung ventilator.When for CPAPDuring mask ventilation pattern, according to patient's actual demand, operator's operation regulating valve 5 realizes the size control of gas outlet 3, Jin ErshiThe existing internal pressure of mask body 1 regulation.When regulating valve 5 is by 3 contract fully of gas outlet, the NIV faces controlled entirely available for lung ventilatorCover.
It is preferred that, regulating valve 5 includes the plectrum 51 that catch 53 and regulation gas outlet 3 are open, and catch 53 and plectrum 51 are all provided withPut in gas outlet 3, plectrum 51 can be rotated relative to catch 53.Specifically, can be provided with receiving plectrum 51 on gas outlet 3Sliding groove, rotates plectrum 51, and plectrum 51 is rotated in sliding groove, and then regulation gas outlet 3 is open.
It is more highly preferred to, gas outlet 3 is cylindrical tube, and catch 53 and plectrum 51 are semi-circular piece, it is preferable that the He of catch 53The radius of plectrum 51 is equal, and semicircle side and the side wall of gas outlet 3 of catch 53 are tightly connected, and the center of circle of plectrum 51 passes through bearing pin and gearThe center of circle of piece 53 is rotatably connected.Plectrum 51 can be rotated relative to washer 53, and then regulation gas outlet 3 is open.
Plectrum 51 is stirred for the ease of operator, it is preferable that stir projection 52 provided with projection 52 is stirred in the operating side of plectrum 51It is arranged vertically with the plectrum 51.When needing to adjust the opening of gas outlet 3, stir projection 52 and rotate, stir the drive group of projection 52Piece 51 is rotated, and significantly reduces the operation difficulty for rotating plectrum 51.
Further, mark is pointed out in the outer surface of plectrum 51 provided with turned position, by setting prompting mark so that operatorKnow how that default effect can be reached by rotating plectrum 51 in time.
Further, the openend of catch 53 is provided with the locating part for the spacing end of plectrum 51.For the ease of work peopleThe noninvasive breathing mask of member's processing, it is preferable that locating part and catch 53 are formed in one structure.By setting locating part, it can causeWhen locating part is abutted with plectrum 51, the opening of gas outlet 3 can be blocked stably, add the use scope of noninvasive breathing mask.
In order to improve the comfortableness that patient uses lung ventilator, it is preferable that noninvasive breathing mask also includes being arranged on mask body 1Turbulence structure on inlet end, specifically, as shown in figure 9, turbulence structure is multiple flow-disturbing holes 6, it is preferred that multiple flow-disturbing holes 6Arranged in multi-ring annular, i.e., each annulus is arranged by multiple flow-disturbing holes 6 and formed, it is preferable that the center of circle of multiple annulus of formation is identical.For the ease of staff's processing flow-disturbing hole 6, it is preferable that flow-disturbing hole 6 is circular hole, flow-disturbing hole 6 be diameter according to the actual requirements depending on,The application is not specifically limited.
Further, the noninvasive breathing mask also includes the diaphragm for shield portions flow-disturbing hole 6, and diaphragm is located at mask body1 outer surface, is closed during air inlet, is opened when venting one's pent-up feelings.In order to improve flow-disturbing effect, it is preferred that diaphragm is blocked positioned at centerFlow-disturbing hole 6.As the patient exhales, diaphragm is opened in mask body 1 in the presence of gas, when the patient inhales, and diaphragm is closed.
Certainly, turbulence structure can be the diaphragm being provided separately within mask body 1, and diaphragm is provided with venthole, gasThe venthole that works enters air inlet 2.
On the basis of above-mentioned each scheme, it is preferable that air inlet 2 is located at the top of gas outlet 3, the outlet side of gas outlet 3 and troublePerson's mouth and nose are just right, and the angle between the airintake direction of air inlet 2 and the outgassing direction of gas outlet 3 is acute angle.Patient is in use, adoptEntered with top, bottom outlet, it is to avoid gas flings nostril in air inlet 2, further increase the safety in utilization of lung ventilator.
A kind of lung ventilator that the application is provided includes instrument body and the noninvasive breathing mask being connected with instrument body, itsIn, noninvasive breathing mask is any of the above-described kind of noninvasive breathing mask, and other devices are prior art, and the application is repeated no more.
