Figure 14 A-Figure 14 E is exemplified with valve loader 300, valve 20 being loaded into the method in deployment devices 10.Some reference numbers of parts in Figure 14 A-Figure 14 E with those previously for example, for the described reference number of valve loader 100 identical or close (, compression shell 310 is with respect to compression shell 110).Should be understood that these parts are identical or approximate in function in function with previously described parts.The valve loader 300 of Figure 14 A-Figure 14 E shows some modification of the valve loader of Fig. 2-Fig. 9 C.

In some embodiments, deployment devices 10 can comprise endoscope, bronchoscope, or has a certain other equipment in inner passage or the chamber that wherein can insert medical valve.In some embodiments, valve 20 being loaded into method in transfer device 10 comprises the far-end 310B of compression shell 310 is positioned in the service aisle of deployment devices 10.The method also can comprise uses thumb 7 or other modes that plunger 380 is promoted towards guide member 330 along distal direction, as shown in Figure 14 A-Figure 14 B.Plunger 380 can cause the bonding part 388 of plunger 380 to promote valve 20 towards the far-end 310B of compression shell 310 along distal direction towards the movement of guide member 330, and valve 20 release compression shells 310 are entered to deployment devices 10.After valve 20 is inserted into deployment devices 10, user can pull piston cap 384 away from guide member 330, causes plunger 380 to move along proximal direction, as shown in Figure 14 C-Figure 14 D.Piston cap 384 is pulled away from guide member 330 and can contribute to the bonding part 388 of plunger 380 to depart from from valve 20.In some embodiments, valve loader 300 comprises an elastic component 360 (for example, spring), and when plunger 380 moves along distal direction, described elastic component can be compressed.Elastic component 360 can be along proximal direction biased piston 380, and person capable of reducing using manually pulls piston cap 384 away from the needs of guide member 330.The method makes valve loader 300 move away from deployment devices 10 after also can being included in valve 20 being loaded in deployment devices 10, as shown in Figure 14 E.

Figure 15-Figure 17 shows medical valve 20 is loaded into the method in the service aisle 12 of transfer device 10.As shown in figure 15, valve 20 can be directly loaded in the compression shell 110 of valve loader 100.In some embodiments, in the situation that not using sleeve (cartridge) or other preloaded devices, valve can be directly loaded in valve loader 100.The taper angle θ of the tapering part 142 of pressure channel 128 can cause the some parts (for example, valve portion 22) of valve 20 towards central axis 127 compressions of pressure channel 128, as shown in Figure 15 and Figure 16.In some embodiments, pressure channel 128 can comprise one or more grooves 126 as discussed above.In some embodiments, interior when compressed at pressure channel 128 when valve 20, the groove 126 in the tapering part 142 of pressure channel 128 can contribute to aim at valve 20.In some embodiments, when valve portion 22 interior when compressed at the tapering part 142 of pressure channel 128, the overlap each other probability of (for example, intersecting) of the rib 34 that groove 126 can contribute to reduce valve portion 22.For example, one or more grooves 126 can engage with one or more ribs 34.Such joint can contribute to reduce one or more ribs 34 and move another the probability in rib 34 around the central axis 127 of compression shell 110.The advantage that reduces the overlapping of rib 34 or intersect between compression period is that this can allow valve 20 spreads during disposing, and when valve 20 expansions and/or deployment, contributes to reduce the probability of damage threshold 20 and/or umbrella part 32.In some embodiments, reduce the overlapping of rib 34 or intersect and can reduce the probability of the winding between the far-end of rib 34.

As shown in figure 16, when valve 20 is loaded onto in valve loader 100, plunger 180 can move along distal direction.Along with plunger 180 moves along distal direction, the bonding part 188 of plunger can engage with the hub 26 of medical valve 20, and can promote valve 20 along distal direction.Along with medical valve 20 is pushed along distal direction, the taper angle θ of the tapering part 142 of pressure channel 128 can cause valve anchor portion 24 and/or valve portion 22 compressions.Along with 24 compressions of valve anchor portion, the articulated jib 36 of anchor portion 24 is aimed at the central axis 127 of pressure channel 128, as shown in figure 16.The compression of the compression of valve portion 22 and articulated jib 26 is to reducing the area of section of valve 20 in the plane of the axis 127 perpendicular to pressure channel 128.The compression of valve 20 can allow within valve 20 fits in the service aisle 12 of deployment devices 10, as shown in figure 17.After valve 20 being promoted to the aperture, distally 118 by valve loader 110 and entering deployment devices 10, the bonding part 188 of plunger 180 can be recalled from the hub 26 of valve 20.Bonding part 188 can be dimensioned, thereby it is enough slightly promoted valve 20 by pressure channel 128, thereby it enough carefully prevents between compressed articulated jib 36 and bonding part 188 and engage when bonding part 188 is pulled away from valve 20 simultaneously.

Figure 18 shows the interior compressed valve 20 of service aisle 12 at transfer device 10.In some embodiments, transfer device can comprise a camera 14 and/or one or more align member 16.When interior when compressed at service aisle 12, grappling tip 38 can be configured to the direction of the axis of " pointing to (point) " passage, and valve 20 is compressed in described passage.In some embodiments, grappling pad 43 can be configured to the orientation of its axis outside of passage, and valve 20 is compressed in described passage.In some configurations, the orientation of above-described compressed valve 20 can contribute to prevent grappling most advanced and sophisticated 38 to damage the wall of service aisle 12 when valve is compressed in service aisle 12.

In some embodiments, valve loader 100 can be loaded with valve 20 by prepackage, afterwards valve loader 100 is passed to the other-end user of doctor or valve loader 100, as shown in figure 15.In some configurations, the valve loader 100 of preloaded can be configured to, for loading single valve 20, afterwards valve loader 100 be abandoned.The above-mentioned configuration of the preloaded valve loader 100 that single is used can be sterilized with ethylene oxide gas or a certain other sterilization methods, then packed for passing to doctor or other-end user.

In some embodiments, valve loader 200 can be pre-installed and be loaded with valve 20, afterwards valve loader 200 is passed to the other-end user of doctor or valve loader 200, as shown in Figure 12 A.In some embodiments, valve loader 200 can be passed to the other-end user of doctor or valve loader 200 with unassembled state.In some configurations, valve loader 200 can be arranged to and dispose a plurality of valves 20.For example, within the user of valve loader 200 can be loaded into compression shell 210 by a valve, and valve 20 is disposed in deployment devices 10.Then, user can disconnect compression shell 210 to connect with the axle collar 270, and within another valve 20 being loaded into the compression shell 210 of valve loader, as shown in figure 19.Need to complete the task how many times that user is used valve loader 200, just this process of disposing valve 20 and the valve loader 200 of reloading be repeated to how many times.
