Background technology
Non-invasive positive pressure ventilation (NPPV) refers to that patient will by the non-invasive mode such as nose cup, oral nose mask or full facepiece mask
Patient is connected with positive pressure respirator carries out assisted ventilation.The invasive ventilation overwhelming majority takes single loop woundless positive pressure respirator, needs
Excess oxygen aspiration is wanted to enter, oxygen is generally connected on mask, single loop woundless positive pressure respirator flow of supplying gas is up to 40L/min extremely
80L/min, and common central oxygen supplying, oxygen cylinder oxygen supply oxygen flow only had and adopt 1L/min to 10L/min, especially family NPPV more
Use molecular-sieve oxygen generator oxygen supply, molecular-sieve oxygen generator oxygen flow be generally 1L/min to 5L/min, such a connected mode causes oxygen
Gas severe dilutes, and causes fraction of inspired oxygen degradation.
Test result shows, it is conventional through mask oxygen inhalation when the fraction of inspired oxygen formula that obtains close to：21%+2% × oxygen
Flow (L/min), and the fraction of inspired oxygen computing formula obtained during nasal tube oxygen inhalation is 21%+4% × oxygen flow (L/min).
It follows that the oxygen concentration even below nasal tube oxygen inhalation obtained when routine is through mask oxygen inhalation, easily causes the waste of oxygen.Face
Bed the course of work in patient carry out noninvasive ventilation treatment purpose be improve its ventilation, oxygenation, to make up simple oxygen
Treatment is only capable of improving the defect of patient's oxygenation, therefore, a kind of non-invasive ventilation mask is needed in clinical position, can both improved
Fraction of inspired oxygen, saves oxygen, more adapts to family's invasive ventilation, and the aeration status of patient is had no adverse effects.

Details.It will be appreciated by those skilled in the art that without some details, the utility model can equally be implemented.In some realities
In example, it is not described in detail for method well known to those skilled in the art, means, element, in order to highlight the utility model
Purport.
Embodiment 1
Fig. 1 shows the main parallax stereogram for the non-invasive ventilation mask that the utility model embodiment is provided, and Fig. 2 shows that this practicality is new
The schematic diagram for the non-invasive ventilation mask use state that type embodiment is provided.With reference to shown in Fig. 1 and Fig. 2, the mask includes：Mask sheet
Body 1, invasive ventilation pipe joint 2, nose conduit 3 and oxygen connecting hole 4.
Wherein, the formation of mask body 1 inner chamber, the inner chamber is used for the mouth and nose for covering user, enables a user to interior to this
Chamber air-breathing, expiration.Invasive ventilation pipe joint 2 is arranged at the center position of mask body 1, for connecting noninvasive ventilator pipeline.
The lower section of invasive ventilation pipe joint 2 is provided with oxygen connecting hole 4.Nose conduit 3 is passed through the inner chamber through oxygen connecting hole 4,
In use, nose conduit 3 is passed through user's nasal cavity for user's oxygen supply.
In a kind of preferably implementation, the non-invasive ventilation mask that the utility model embodiment is provided also includes：Hard
Conduit 5.Hard conduit 5 enters the inner chamber through oxygen connecting hole 4, is tightly connected between hard conduit 5 and oxygen connecting hole 4.
Fig. 3 shows the rear perspective view for the non-invasive ventilation mask that the utility model embodiment is provided, to show hard conduit 5
Enter the state of the inner chamber through oxygen connecting hole 4.
The hard conduit 5 can be a conduit or be connected respectively with the two ends of oxygen connecting hole 4 two lead
Pipe.Nose conduit 3 can be divided into two sections, and the two ends with hard conduit 5 are connected respectively.By setting the hard conduit 5 can be in order to
Oxygen is connected to the inner chamber, the effect saved oxygen, improve fraction of inspired oxygen is reached.
Following experimental result, it was confirmed that the effect for the non-invasive ventilation mask oxygen supply that the utility model embodiment is provided.
In simulated lung invasive ventilation model, result of the test is shown, under the conditions of different pressures of inspiration(Pi), through nose conduit in mask
When the fraction of inspired oxygen that oxygen supply is obtained is obviously higher than through mask oxygen inhalation.(being shown in Table 1-4).
Table 1IPAP8cmH2During O through mask oxygen inhalation and through in mask during nasal catheter oxygen inhalation fraction of inspired oxygen measured value
Table 2IPAP12cmH2During O through mask oxygen inhalation and through in mask during nasal catheter oxygen inhalation fraction of inspired oxygen measured value
Table 3IPAP16cmH2During O through mask oxygen inhalation and through in mask during nasal catheter oxygen inhalation fraction of inspired oxygen measured value
Table 4IPAP20cmH2During O through mask oxygen inhalation and through in mask during nasal catheter oxygen inhalation fraction of inspired oxygen measured value
In human trial, as a result show, when healthy volunteer and COPD merge II respiratory failure type patient's invasive ventilations,
Compared through mask oxygen inhalation with through nasal catheter oxygen inhalation in mask, through the PtcO2 in mask during nasal catheter oxygen inhalation apparently higher than through mask
Oxygen supply；PtcCO2 changes without conspicuousness simultaneously.(being shown in Table 5-6).
The healthy volunteer P of table 5tcO2、PtcCO2Contrast
Table 6COPD merges II respiratory failure type patients PtcO2、PtcCO2Contrast
Thus, the non-invasive ventilation mask that the utility model embodiment is provided, by nasal catheter oxygen inhalation in mask, can not only be carried
High fraction of inspired oxygen, saves oxygen, more adapts to family's invasive ventilation, and patients carbon dioxide's partial pressure is had no significant effect.
