Fig. 4 illustrates the example of airway adapter coupler 170.With reference to the example of the airway adapter 100 in figure 3B, airway adapter coupler 170 can be connected with the first end 113 of connector body 111.In certain embodiments, airway adapter coupler 170 comprises wiper seals portion 172, and wiper seals portion 172 has inner flange and ingate 194.In some aspects, the inner flange in wiper seals portion 172 can comprise the transverse wall relative to longitudinal center line 101.But in certain embodiments, inner flange can be angled relative to longitudinal center line.Such as, inner flange can tilt towards the second end 119 of connector body 111, thus when being connected with the entrance 110 of airway adapter 100, forms frusto-conical wiper seals portion or friction means.In addition, wiper seals portion 172 and relevant aperture can be configured to receive intake guide or gas medical apparatus, to enter the slender cavity 115 of connector body 111.It should be understood that in certain embodiments, airway adapter coupler 170 is connected to intake guide cover, and can be connected to the first end 113 of the connector body 111 of airway adapter 100 removedly.

Fig. 5 illustrates the example of multi-purpose valve.According to some embodiment, valve 120 comprises the edge 123 along outer circumference.But in other embodiments, the edge of multi-purpose valve can be various shape (such as, avette, square, hexagon, pentagon etc.).According to some embodiment, valve 120 also comprises the membranous part 125 of elastically deformable.Membranous part 125 is integrally connected to edge 123, and comprises the multiple valve sections 221 (see the additional aspect relevant to valve section 221, and Fig. 6 A to Fig. 6 F and Fig. 6 K to Fig. 6 N illustrates more than one slit 223) limited by more than one slit 223.

In certain embodiments, valve section 221 can comprise first area 225 and second area 227.The primary seal portion 231 of valve 120 is formed by the multiple valve sections 221 be arranged on membranous part 125.Valve 120 also comprises 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 larger sealing of valve 120, and it allows intake guide (or other medical apparatus and instruments) to pass.After removing intake guide, its initial no-bias structure 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, 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 maintenance sealing on atmospheric pressure.Secondary seal portion 233 has the first fracture pressure 235, and primary seal portion 231 has and is different from second of the first fracture pressure 235 and breaks (or cracking) pressure.Valve 120 can be configured to: the first fracture pressure can be limited in the scope between lower threshold 235a as shown in the curve chart of Fig. 5 and upper limit threshold 235b (for exemplary purposes, not drawing in proportion).In some embodiments, lower threshold 235a can be set in about 68cmH ₂o, upper limit threshold 235b can be set in about 188cmH ₂o.Like this, valve 120 can be configured to: can complete aerating in the scope between lower threshold 235a and upper limit threshold 235b; In some embodiments, upper limit threshold 235b is close to lower threshold 235a.Such as, be positioned at and provide 120cmH with the first fracture pressure 235 scope ₂intake 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 can perform aerating in slender cavity 115, minimally (even completely not) affects the ventilatory between scavenge port 130 and pneumostome 160 simultaneously.In addition, it should be understood that, in certain embodiments, second of primary seal portion 231 breaks/and cracking pressure 237 can be greater than the scope of the first fracture pressure 235 significantly, thus air-breathing or vacuum pressure differential can not produce significant impact to primary seal portion 231.In this respect, according to some embodiment, break or ftracture relevant to the whole primary seal portion 231 of valve 120 may be caused by the insertion of medical apparatus and instruments, and relevant with scraping function to cleaning of valve 120.

At mechanically ventilated breathing circuit (such as, the ventilation source applied at scavenge port 130 place utilizes airway adapter 100 to lead via pneumostome 160 artificial airway 165) normal operating in, the pressure differential at valve 120 place of airway adapter 100 remains on 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 separated by medical apparatus and instruments (such as, utilize the end of the intake guide in the slender cavity 115 of connector body 111 from intake guide air-breathing), the pressure differential at valve 120 place can be in or higher than the first fracture pressure 235, but lower than the second fracture pressure 237.In this differential pressure range, the impact of such pressure differential during operation artificial airway 100 will cause valve 120 to show as valve 120b---and the second sealing 233 ftractures.

Like this, effective aerating operation can be completed.It should be understood that, larger power may be needed (such as, run through the frictional force of the medical apparatus and instruments of valve 120) primary seal portion 231 is ftractureed, this can be regarded as expanding the circumferential area that diameter is the membranous part 125 of the valve 120 of more than one slit 223.But, it should be noted that, valve 120 is configured to: the suction of hope or suction force range can not cause primary seal portion 231 to ftracture, because this cracking during aerating can make too much air discharge from ventilation source, so that produces undesirable harmful effect to the respiratory function of patient.

According to some aspect, the membranous part 125 of valve 120 can comprise sloped region 127 and sectional area 129.Sloped region 127 (such as, frusto-conical, cavetto, projection etc.) can be used as bias mechanism, so that after removing intake guide or other medical apparatus and instruments, helps valve 120 to return to initial sealing structure.In addition, in some aspects, be arranged on membranous part 125 and can be integrally arranged on sectional area 129 with the more than one slit 223 forming multiple valve section 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 of the membranous part 125 in sectional area 129 starts just existence from the first area 225 of valve section 221 of structure and second area 227 forming primary seal portion 231 and secondary seal portion 233.

As shown in the example in fig. 5, the edge 123 of valve 120 circumferentially shape and its width (W) can be 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 enough wide, to such an extent as to when valve 120 remains in the valve holding structure of airway adapter 100, still can realize enough air-tightness.But, can according to one of above-mentioned drum type volume many distinguishing characteristicss understanding valve 120.Such as, although the membranous part 125 in some embodiment can comprise sloped region 127, at least according 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 in valve holding structure by compression time), the sloped region 127 of membranous part 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 regarded as roughly in plane, and thus multiple valve section can extend to valve 120 and is used as ftractureing in the two sides of block piece or sealing or region.

In addition, although multiple material can be used to make or formed valve 120 according to this utility model each side, in certain embodiments, edge 123 and membranous part 125 can include organosilicon polymer, one of 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 comprise 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 section 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 comprise the graded thickness gone up at least partially being positioned at more than one first area 225.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 near or be in the infall of more than one slit 223, and the second thickness 125B can be limited at close to or be in transition region or the boundary (such as, Fig. 6 A, Fig. 6 E and Fig. 6 F) in secondary seal portion 233.According to some aspect, the second thickness 125B is greater than the first thickness 125A.The change of thickness allows the reaction of valve 120 pairs of air pressures (such as fracture pressure) and is change with the interaction of the medical apparatus and instruments (such as, intake guide) just passed from valve 120.

Valve section 221 comprises: 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 comprises the first radius R 2, and second surface comprises the second radius R 4.In certain embodiments, the first radius R 2 and the second radius R 4 unequal.In an embodiment, the such as embodiment shown in Fig. 6 M to Fig. 6 N, the first radius R 2 can be in the scope of 0.1332 inch to 0.1628 inch, and the second radius R 4 can be in the scope of 0.3555 inch to 0.4345 inch.In an embodiment, the first radius R 2 is 0.148 inch, and the second radius R 4 is 0.395 inch.

In some embodiment (such as the exemplary embodiment shown in Fig. 6 G), more than one valve section 221 can also comprise the more than one elevated regions 224 (such as Fig. 6 A to Fig. 6 C) be 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, makes the first thickness 125A be less than the projection thickness 125A ' of more than one elevated regions 224.More than one elevated regions 224 can form round or annular projection structure, and it is arranged in the more than one second area 227 of the valve section 221 of more than one first area 225 (such as Fig. 6 B).In other embodiments, in the more than one first area 225 that more than one elevated regions 224 can be arranged on valve section 221 simultaneously 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 arranged to away from more than one first area 225, so that such as when intake guide (or other medical apparatus and instruments) inserts through valve 120, the end close to more than one slit 223 that above-mentioned elevated regions is positioned at membranous part 125, there is larger frictional force or resilience force part near.

In this respect, the protuberance of more than one elevated regions 224 (such as, relative to adjacent part, the discontinuous place of thickness) can be arranged on the end face of membranous part 125 of valve 120, this end face is towards the entrance for receiving intake guide (when being such as assembled in airway adapter 100).During intake guide inserts, valve 120 and multiple valve section 221 thereof can be opened and comply with the direction of conduit movement.Such as, according to some aspect, when intake guide starts to retract from artificial airway, contacted with intake guide by more than one elevated regions 224 and the frictional force that produces can make valve section 221 overturn, thus rapidly and consistently by valve 120 towards the direction traction of retracting.Therefore, intake guide to be arranged on or more than one elevated regions 224 near the more than one first area 225 of the end of each valve section 221 and/or the other parts of more than one valve section 221 can be configured to: when will be retracted from artificial airway, increase extra radial direction contact or power (such as, providing better traction).

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

In certain embodiments, more than one elevated regions 224 can be formed by the material identical with the other parts of membranous part 125.But in other embodiments, more than one elevated regions 224 can be formed as comprising 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 greater than the second thickness 125B of more than one first area 225, and can provide enough rigidity for the valve 120 in operation airway adapter 100.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.

In addition, as shown in the exemplary embodiment in Fig. 6 G, valve 120 can have the 3rd region 229, region the 229, three and surround more than one first area 225 and more than one second area 227.3rd region 229 can comprise the ogival section biasing characteristics be arranged near side edge section.In some aspects, ogival section biasing characteristics comprises the summit thickness larger than the first thickness of more than one first area.Such as, the 3rd region 229 can have the four thickness 125D (such as summit thickness) larger than the first thickness 125A, 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 can turn back to no-bias position after removing intake guide to make valve 120, simultaneously for the scraping function of multiple valve section 221 provides additional support to provide the bias voltage function of valve 120 (Fig. 3 B).Such as, in initial lax or no-bias position, can not there be any contact in 3rd region 229 (such as radial protrusion part) of membranous part 125 particularly membranous part 125 with valve casing inside (such as, the inner inclination wall portion 117 (Fig. 3 B) of airway adapter 100).After intake guide inserts, when intake guide starts to retract and retracts valve 120 along the direction of retraction movement, the 3rd region 229 (such as radial protrusion part) can be moved and contact inner inclination wall portion 117.

Therefore, this contact force can provide support for intake guide of swiping when intake guide is retracted, and provides " pushing away " resilience force when intake guide is retracted completely and valve 120 starts to reseal.The process of retracting, the ogival section biasing characteristics in the 3rd region 229 allows valve section 221 to overturn, so that by valve 120 towards the direction tractive of retracting.In this respect, the ogival section biasing characteristics in the 3rd region 229 may be used for supporting valve 120 rapidly (such as, do not have or minimum delay) and suitable self the resealing of (such as, No leakage).In other side, such as, 3rd region 229 can also provide friction control function and the bias voltage 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, side direction or transverse shifting (Fig. 3 B) relative to the longitudinal center line 101 of airway adapter 100), and no-bias position can be turned back 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 comprise the ogival section biasing characteristics be arranged near side edge section, and this ogival section biasing characteristics comprises bending section 229A and two opposed wall portion 229B, 229C.Therefore, according to some embodiment, the 3rd region 229 can comprise the circumference pleated corrugated part (circumferentialaccordionbellow) with roughly V-shaped section, to provide shape and the flexibility of improvement.In some aspects, ogival section biasing characteristics can comprise the summit thickness larger than the first thickness of more than one first area.Such as, the 3rd region 229 can have the four thickness 125D (such as, the summit thickness at bending section 229A place) larger than the first thickness 125A.In certain embodiments, the 4th thickness 125D can be thicker than first area, but thinner than the 3rd thickness 125C.Therefore, relative to the intake guide (or other medical apparatus and instruments) running through 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 voltage function of valve 120, when having removed via valve 120 with the end of convenient intake guide and inserted inlet region or the clean room of airway adapter 100, just retracting from artificial airway along with intake guide (or other medical apparatus and instruments) and turning back to no-bias position (such as, revert to the V-shaped section that auxiliary valve section 221 is closed completely), two opposed wall portion 229B, 229C can (such as, V-shaped section be closed or is narrowed) 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 auxiliary venting valve 120 make valve 120 turn back to no-bias position (such as, shutoff valve section 221 reseal valve 120).In addition, such as, during airway adapter 100 operates, when intake guide (it has surface that is moistening or drying) starts retract and retract valve 120 along retraction moving direction, the 3rd region 229 can promote the upset of valve section 221.
