In certain embodiments, valve section 221 can include first area 225 and second area 227.The primary seal portion 231 of valve 120 is formed by the multiple valve sections 221 being arranged in film portion 125.Valve 120 also includes secondary seal portion 233.Secondary seal portion 233 is arranged by the more than one first area 225 of valve section 221 and is formed.In this respect, primary seal portion 231 refers to the bigger sealing of valve 120, and it allows intake guide (or other medical apparatus and instruments) to pass.After removing intake guide, the no-bias structure that it is initial is recovered in primary seal portion 231.The secondary seal portion 233 of valve 120 refers to less sealing (such as, the sealing less than primary seal portion 231), it allows and regulates the amount of the air entering slender cavity 115 from air-exchanging chamber 135, in order to clean intake guide after fetching intake guide from the air flue of artificial airway 165 or patient.Therefore, according to some aspect, the secondary seal portion 233 of valve 120 is used as air entraining valve.

As shown in the curve chart of Fig. 5, valve 120 is configured to bear pressure differential to a certain degree and holding sealing on atmospheric pressure.Secondary seal portion 233 has the first fracture pressure 235, and primary seal portion 231 has and is different from the second of the first fracture pressure 235 and ruptures (or cracking) pressure.Valve 120 can be configured to: the first fracture pressure can be limited between the lower threshold 235a as shown in the curve chart of Fig. 5 and upper limit threshold 235b in the range of (for exemplary purposes, being not necessarily to scale).In some embodiments, lower threshold 235a may be set in about 68cmH₂O, upper limit threshold 235b may be set in about 188cmH₂O.So, valve 120 can be configured to: can between lower threshold 235a and upper limit threshold 235b in the range of complete aerating；In some embodiments, upper limit threshold 235b is close to lower threshold 235a.Such as, it is positioned at the first fracture pressure 235 scope offer 120cmH₂Intake guide in the slender cavity 115 of the connector body 111 of O vacuum pressure may cause secondary seal portion 233 to ftracture in a controlled manner, thus aerating in slender cavity 115 can be performed, the ventilatory between the ventilation mouth 130 of minimally (the most not) impact simultaneously and pneumostome 160.Further, it is understood that in certain embodiments, the second of primary seal portion 231 rupture/and cracking pressure 237 can be significantly more than the scope of the first fracture pressure 235, thus air-breathing or vacuum pressure differential will not produce significant impact to primary seal portion 231.In this respect, according to some embodiment, rupture or ftracture be probably relevant to the whole primary seal portion 231 of valve 120 is caused by the insertion of medical apparatus and instruments, and relevant to the cleaning of valve 120 and scraping function.

At mechanically ventilated breathing circuit (such as, ventilation mouth 130 at apply ventilation source utilize airway adapter 100 to guide artificial airway 165 via pneumostome 160) normal operating in, the pressure differential at the valve 120 of airway adapter 100 is maintained at the first fracture pressure less than 235.Under the pressure differential of this low scope, such pressure differential will show as valve 120a to the impact of the operation of valve 120.

According to some embodiment, when applying suction on entrance 110, when valve 120 is not physically separate from by medical apparatus and instruments (such as, utilize the end of intake guide in the slender cavity 115 of connector body 111 from intake guide air-breathing), pressure differential at valve 120 at or greater than the first fracture pressure 235, but can be less than the second fracture pressure 237.In this differential pressure range, the impact during operation artificial airway 100 of such pressure differential will cause valve 120 to show as valve 120b the second sealing 233 ftractureing.

As such, it is possible to complete effective aerating operation.It should be understood that, bigger power may be needed (such as, run through the frictional force of the medical apparatus and instruments of valve 120) make primary seal portion 231 ftracture, this circumferential area that can be considered to expand the film portion 125 of the valve 120 of a diameter of more than one slit 223.But, it should be noted that, valve 120 is configured to: desired suction or suction force range are not result in that primary seal portion 231 ftractures, because this cracking during aerating can make too much air discharge from ventilation source, so that the respiratory function of patient is produced undesirable harmful effect.

According to some aspect, the film portion 125 of valve 120 can include sloped region 127 and sectional area 129.Sloped region 127 (such as, frusto-conical, cavetto, projection etc.) can serve as bias mechanism, in order to after removing intake guide or other medical apparatus and instruments, helps valve 120 to return to initial sealing structure.Additionally, in some aspects, it is arranged in film portion 125 and can be integrally provided on sectional area 129 with the more than one slit 223 forming multiple valve sections 221.Sectional area 129 can be general planar, or forms plateau relative to sloped region 127；It should be understood, however, that the change of the thickness in the film portion 125 in sectional area 129 starts to exist for from the first area 225 of the valve section 221 of the structure forming primary seal portion 231 and secondary seal portion 233 and second area 227.

As shown in the example in fig. 5, the edge 123 of valve 120 can circumferentially shape and its width (W) less than the radius (R) at edge 123.In this respect, the width (W) at edge 123 can limit the volume (V) in drum type of valve 120.The width (W) at edge 123 can be sufficiently wide, to such an extent as to when the valve that valve 120 is maintained at airway adapter 100 keeps in structure, remains to realize enough air-tightness.But, it is possible to according to one of above-mentioned drum type volume many distinguishing characteristicss understanding valve 120.Such as, although the film portion 125 in some embodiment can include sloped region 127, but according at least to some embodiment of valve, sloped region 127 can not be extended into Duckbill type structure.Therefore, in certain embodiments, when valve is in no-bias structure (such as, when not to valve 120 apply pressure differential and edge 123 do not compressed in valve keeps structure time), the sloped region 127 in film portion 125 and sectional area 129 can be arranged in drum type volume (V) by the width (W) at edge 123.Therefore, some example of valve 120 can be considered substantially planar, thus multiple valve section can extend to valve 120 and is used as ftractureing in block piece or the two sides of sealing or region.

Although additionally, multiple material can be used to make or formed the valve 120 according to this utility model each side, but in certain embodiments, edge 123 and film portion 125 can include one of organosilicon polymer, polyurethane or thermoplastic polymer elastomer.

Fig. 6 A to Fig. 6 F and Fig. 6 K to Fig. 6 N illustrates the limiting examples of multi-purpose valve.According to various aspects, the valve section 221 of valve 120 can include more than one first area 225 and more than one second area 227.According to some aspect, the primary seal portion 231 of valve 120 can be formed by multiple valve sections 221, and the secondary seal portion of valve 120 can be arranged by the more than one first area 225 of more than one valve section 221 and be formed.More than one first area 225 can include being positioned at more than one first area 225 at least some of on graded thickness.Such as, sectional view in the example of additional reference Fig. 6 G and Fig. 6 H, first thickness 125A of first area 225 can be limited at the infall near or at more than one slit 223, and the second thickness 125B can be limited at the transition region approaching or at secondary seal portion 233 or boundary (such as, Fig. 6 A, Fig. 6 E and Fig. 6 F).According to some aspect, the second thickness 125B is more than the first thickness 125A.The change of thickness allows the valve 120 interaction to the reaction of air pressure (such as fracture pressure) and with the medical apparatus and instruments (such as, intake guide) just passed from valve 120 to be change.

Valve section 221 includes: first surface, and it is near the leading edge 122 of valve 120；And second surface, it is away from the leading edge 122 of valve 120.First surface includes the first radius R2, and second surface includes the second radius R4.In certain embodiments, the first radius R2 and the second radius R4 is unequal.In an embodiment, such as the embodiment shown in Fig. 6 M to Fig. 6 N, the first radius R2 may be in the range of 0.1332 inch to 0.1628 inch, and the second radius R4 may be in the range of 0.3555 inch to 0.4345 inch.In an embodiment, the first radius R2 is 0.148 inch, and the second radius R4 is 0.395 inch.

In some embodiment (exemplary embodiment shown in such as Fig. 6 G), more than one valve section 221 can also include the more than one elevated regions 224 (such as Fig. 6 A to Fig. 6 C) being positioned on more than one first area 225 and/or second area 227.Therefore, more than one elevated regions 224 can be formed as pearl or projection (such as Fig. 6 A and Fig. 6 G) at the infall of more than one slit 223 so that the first thickness 125A is less than projection thickness 125A of more than one elevated regions 224 '.More than one elevated regions 224 can form round or annular projection structure, in the more than one second area 227 of its valve section 221 being positioned close to more than one first area 225 (such as Fig. 6 B).In other embodiments, more than one elevated regions 224 can be simultaneously located in the more than one first area 225 of valve section 221 and more than one second area 227 (such as Fig. 6 C), and some elevated regions in more than one elevated regions 224 can be remotely located from more than one first area 225, so that such as when intake guide (or other medical apparatus and instruments) inserts through valve 120, above-mentioned elevated regions is positioned at the end close to more than one slit 223 in film portion 125, has near the part of bigger frictional force or resilience force.

In this respect, the protuberance of more than one elevated regions 224 is (such as, relative to adjacent part, thickness is discontinuously located) can be arranged on the end face in film portion 125 of valve 120, this end face is towards being used for receiving the entrance of intake guide (when being such as assembled in airway adapter 100).During intake guide inserts, valve 120 and multiple valve section 221 thereof can open and comply with the direction that conduit moves.Such as, according to some aspect, when intake guide starts to retract from artificial airway, more than one elevated regions 224 contact with intake guide and the frictional force that produces can make valve section 221 overturn, thus draw towards the direction retracted rapidly and consistently by valve 120.Therefore, it is arranged on or can be configured near the more than one elevated regions 224 of the end of each valve section 221 and/or the more than one first area 225 of the other parts of more than one valve section 221: when intake guide to be retracted from artificial airway, increase extra radially contacting with or power (such as, it is provided that preferably traction).

Here it should further be appreciated that, more than one elevated regions 224 may be located in more than one first area 225 or near more than one first area 225 (infall of at least some of slit such as, being located on or near in more than one slit 223).More than one elevated regions 224 can assist and keep contacting with intake guide direct (such as, preventing the thinner part 125A of first area 225 and 125B bend relief or the outer surface away from intake guide) similarly.Additionally, when intake guide is fully retracted, the additional thickness of more than one elevated regions 224 of the infall being positioned adjacent to or being positioned at more than one slit 223 can also reseal or close by auxiliary valve 120 quickly and/or more safely.

In certain embodiments, more than one elevated regions 224 can be formed by the material identical with the other parts in film portion 125.But, in other embodiments, more than one elevated regions 224 can be formed as including other material or compound, to improve rigidity or the frictional behavior of more than one elevated regions 224.

In some aspects, more than one second area 227 can have the 3rd thickness 125C.According to some aspect, the 3rd thickness 125C of more than one second area 227 is more than the second thickness 125B of more than one first area 225, and can be for operating the rigidity that the valve 120 in airway adapter 100 provides enough.In this respect, during taking out intake guide from artificial airway 165, the thickness of more than one second area 227 and rigidity can assist fixing and scraping intake guide.

Additionally, as shown in the exemplary embodiment in Fig. 6 G, valve 120 can have the 3rd region 229, the 3rd region 229 surrounds more than one first area 225 and more than one second area 227.3rd region 229 can include the ogival section biasing characteristics being arranged close to side edge section.In some aspects, ogival section biasing characteristics includes the summit thickness bigger than the first thickness of more than one first area.Such as, the 3rd region 229 can have the fourth thickness 125D (such as summit thickness) bigger for thickness 125A than first, and thicker than the second thickness 125B and/or the 3rd thickness 125C in certain embodiments.Therefore, 3rd region 229 can utilize the inner inclination wall portion 117 of airway adapter 100 to provide the bias function (Fig. 3 B) of valve 120 so that valve 120 can return to no-bias position after removing intake guide, and the scraping function for multiple valve sections 221 provides additional support simultaneously.Such as, in initial lax or no-bias position, can not there be any contact in 3rd region 229 (such as radial protrusion part) in particularly film portion 125 of film portion 125 with valve casing internal (such as, the inner inclination wall portion 117 (Fig. 3 B) of airway adapter 100).After intake guide inserts, when intake guide starts retraction and the direction along retraction movement retracts valve 120, inner inclination wall portion 117 can be moved and contact in the 3rd region 229 (such as radial protrusion part).

Therefore, intake guide of swiping when this contact force can be retracted for intake guide provides and supports, and provides " pushing away " resilience force when intake guide is fully retracted and valve 120 starts to reseal.In the process retracted, the ogival section biasing characteristics in the 3rd region 229 allows valve section 221 to overturn, in order to by valve 120 towards the direction tractive retracted.In this respect, the ogival section biasing characteristics in the 3rd region 229 may be used for supporting valve 120 (such as, do not have or minimum delay) rapidly and suitable self the resealing of (such as, No leakage).In other side, such as, 3rd region 229 may be provided for friction control function and the bias function of valve 120, valve 120 is made can more to adapt to the movement of intake guide (such as while being run through by intake guide, laterally or transverse movement (Fig. 3 B) relative to the longitudinal center line 101 of airway adapter 100), and no-bias position can be returned to after removing intake guide.

In other embodiments, such as in the exemplary embodiment shown in Fig. 6 H, 3rd region 229 of valve 120 can include the ogival section biasing characteristics being arranged close to side edge section, and this ogival section biasing characteristics includes bending section 229A and two opposed wall portion 229B, 229C.Therefore, according to some embodiment, the 3rd region 229 can include circumference pleated corrugated part (circumferentialaccordionbellow) with generally V-shaped section, in order to provides the shape and flexibility improved.In some aspects, ogival section biasing characteristics can include the summit thickness bigger than the first thickness of more than one first area.Such as, the 3rd region 229 can have the fourth thickness 125D (such as, summit thickness bending section 229A at) bigger for thickness 125A than first.In certain embodiments, the 4th thickness 125D can be thicker than first area, but thinner than the 3rd thickness 125C.Accordingly, with respect to running through the intake guide (or other medical apparatus and instruments) of valve 120, the 3rd region 229 can provide consistent radial force and frictional force.

Such as, the 3rd region 229 in the exemplary embodiment of Fig. 6 H can provide the bias function of valve 120, so that when the end of intake guide has removed via valve 120 and has inserted inlet region or the cleaning room of airway adapter 100, along with intake guide (or other medical apparatus and instruments) is just being retracted from artificial airway and returning to no-bias position (such as, revert to the V-shaped section that auxiliary valve section 221 completely closes), two opposed wall portion 229B, 229C can (such as, V-shaped section be closed or narrow) close to each other in the terminal part office of bending section 229A.Therefore, during intake guide insertion/retraction operation, the 3rd region 229 can keep its shape and flexibility, thus assist venting valve 120 and make valve 120 return to no-bias position (such as, close valve closing section 221 and reseal valve 120).It addition, such as during airway adapter 100 operates, when intake guide (it has surface that is moistening or that be dried) starts retract and retract valve 120 along retraction moving direction, the 3rd region 229 can promote the upset of valve section 221.
