A kind of Transnasal vent device, comprise for being fitted in patient face and pasting to form the nose of the venting cavity being communicated with patient's nasal cavity, described nose pastes and comprises plastic material layer and be formed on the sticker layer on described plastic material layer, and described nose pastes and realizes described laminating by described sticker layer; Described nose sticks and is at least provided with a guide hole for passing for airway, and nose fits in after patient face, and described guide hole is relative with patient's naris position.
Preferably:
Also comprise airway.
The external diameter of described airway is greater than the aperture of described guide hole under non-squeezed state, thereby described airway is sticked through being fixed on by the deformation pressure of guide hole described nose after described guide hole.
Described guide hole comprises an air inlet guide hole and the guide hole of giving vent to anger, and described airway comprises an air induction conduit and an outtake tube, and described air induction conduit enters patient's nasal cavity but do not contact with patient's nasal cavity through described air inlet guide hole; The guide hole of giving vent to anger described in described outtake tube passes is communicated with described venting cavity.
Described outtake tube is provided with outgassing nonreturn valve.
Described guide hole comprises air inlet guide hole and the guide hole of giving vent to anger, and described airway comprises air induction conduit, and described air induction conduit enters patient's nasal cavity but do not contact with patient's nasal cavity through described air inlet guide hole; The described guide hole of giving vent to anger is communicated with described venting cavity with atmosphere.
The end of described airway is provided with scale marker.
Described plastic material layer is layer of silica gel.
Compared with prior art, Transnasal vent device of the present utility model, by being provided with one of the plasticity nose subsides formation of guide hole, be communicated with and the venting cavity of isolation relative to atmosphere with nasal cavity, by guide hole, airway is fixed simultaneously, thereby make the nasal cavity that enters patient that airway can be unsettled, and do not touch with patient's nasal cavity, patient's nasal cavity is not damaged.Especially for baby, Transnasal vent device of the present invention has more easy to use, effectively protects the effect of the tender and lovely skin of baby.

The specific embodiment
Preferred embodiment the utility model is described in further detail to contrast accompanying drawing combination below.
Embodiment 1
As shown in Fig. 1,3 and 5, the Transnasal vent device of the present embodiment comprises, nose subsides 100, and this nose pastes and is comprised of plastic material layer 110 and sticker layer 120, nose pastes 100 and is provided with two for passing and fixing guide hole 101 for airway 200, and the plastic material layer of the present embodiment adopts layer of silica gel.Because pasting 100, nose adopts plastic material layer 110, thereby can adapt to patient's nose and face's shape and carry out certain moulding, thereby adapt to patient's face mask and patient's nose skin attachement around, then by sticker layer 120, be fixedly attached to patient face, after pasting, nose pastes 100 and just can form a venting cavity 400 being communicated with nasal cavity 300 with patient's below, nostril; The position of guide hole 101 arrange make nose paste 100 be affixed on patient face after, the position of this guide hole 101 is relative with patient's naris position, passes guide hole 101 and enters patient's nasal cavity, and can not contact with patient's nasal cavity thereby be convenient to airway 200.The quantity of the guide hole 101 of the present embodiment is two, and one of them is for air induction conduit, and another one is for outtake tube or be directly communicated with venting cavity 400 and atmosphere.Certainly, these two guide holes also can be all for air induction conduit, and two air induction conduits can be fixed by two guide holes 101 respectively, and enter patient's nasal cavity, and in this case, patient needs with a mouthful expiration.
When adopting outtake tube, preferably adopt and be provided with the outtake tube of outgassing nonreturn valve, thereby suck excessive air while avoiding more air-breathing than people.In use, outtake tube also can connect ETCO2 monitor, breathe last malleation generator (while carrying out CPAP ventilation).
For guiding user correctly inserts the suitable degree of depth by airway 200, the end of the airway 200 of the present embodiment is also provided with scale marker 201.
The nose of the present embodiment pastes 100, plays on the one hand the effect that forms venting cavity 400, avoids user to suck a large amount of air; On the other hand, itself or the fixture of airway 200, can be at user's nasal cavity in vacant state for fixing airway 200, and can not touch nasal cavity.In a preferred embodiment, the aperture of guide hole 101 is less than the external diameter of airway under non-squeezed state, thereby airway is being pasted on 100 through being fixed on by the deformation pressure of guide hole nose after guide hole 101.
Embodiment 2
As shown in Figures 2 and 4, the difference of this enforcement and embodiment 1 is only, the guide hole 201 of the present embodiment comprises three, and wherein two of left and right are respectively used to for air induction conduit, centre for common outtake tube connection or directly connect atmosphere.The shape when nose that Figure 4 shows that the present embodiment pastes for patient face.
Above content is in conjunction with concrete preferred implementation further detailed description of the utility model, can not assert that concrete enforcement of the present utility model is confined to these explanations.For this utility model person of ordinary skill in the field; without departing from the concept of the premise utility; can also make some being equal to substitutes or obvious modification, and performance or purposes identical, all should be considered as belonging to protection domain of the present utility model.
