    Technical area
    The present invention relates to a method for assembling two assemblies for forming a laryngeal mask, the first assembly comprising the head of the laryngeal mask having a preassembled supraglottic tube, the tube having at least one respiratory lumen and a guide lumen, and the second assembly being a preassembled one Control unit comprises, consisting of a union nut in which a screw-threaded rod is displaceable relative to the distal end of the tube and to which a pressure member in the form of a link chain and a flexible tension member attack, wherein during assembly of the link chain with the tension member, the second assembly, this is inserted into the guide lumen in the tube of the first assembly.
    State of the art
    From WO 2010/060 227 a laryngeal mask with supraglottic tube with several lumens is known, of which a respiratory lumen of the ventilation air supply and the instrumentation is used. Another lumen serves as a guide lumen in which a guide means for changing the radius of curvature of the tube is stored. The guide means consists of a pressure member consisting of a link chain having a continuous dorsal wall and having various interruptions in the ventral wall, so that the link chain can be correspondingly curved by means of a flexible pulling member. This known laryngeal mask has at the distal end of the supraglottic tube an over-nut in which a traction pin is displaceable relative to the distal end of the supraglottic tube.
    The head of the laryngeal mask and the supraglottic tube may be integrally molded or consist of two parts which are already preassembled. The head of the laryngeal mask together with the supraglottic tube form a first assembly.
    The second module is already assembled today by conventional method on a rotary indexing machine with various stations. This second assembly, which forms a control unit, comprises a union nut in which a screwable tensioning pin is screwed in a first station. In another station then an air connector is added with a nozzle in the supraglottic tube is finally inserted. But this is done only in the inventive method. A flexible pulling element is inserted from the distal side into the pulling pin. Finally, the link chain is fed from the proximal side, wherein the pulling member is guided in a channel passing through the various members chain parts until a Spreitzelement engages the end of the tension member in the proximal end member of the link chain. Now the second module is completely pre-assembled.
    The assembly of the first module with the second module seemed previously only possible manually. The reasons for this are that the parts of the second assembly consist of relatively pressure-resistant plastic parts made predominantly of polyethylene or polypropylene or similar plastics, while the parts of the first assembly, the head of the laryngeal mask and the supraglottic tube of rubber-like TPE Plastic are made. The plastics of this plastic mating of the parts that must be assembled here have completely different physical properties. While the first assembly is hardly dimensionally stable, the second assembly is dimensionally stable in the items with the exception of the elongated link chain and the tension member, which purely purely functional, must be extremely flexible but inelastic. The link chain together with the traction element must now be inserted into the guide lumen in the supraglottic tube. This complicates the fact that the plastic of the link chain in the guide lumen of the supraglottic tube made of TPE material has a relatively high coefficient of friction, and thus is not easy to insert. In addition, the individual links of the link chain are connected only by a relatively thin dorsal wall, as well as the very flexible tension member. Consequently, this results in the introduction hardly any stability and it is therefore not sufficient to introduce only the proximal end of the link chain in the distal end of the guide lumen in the supraglottic tube and then collapse the two assemblies together.
    It is therefore an object of the present invention to provide a method by which the two modules described above are safe and quick to assemble.
    It is a further object of the present invention to provide a suitable for carrying out the inventive method mounting device.
    The first object is achieved by a method of the type mentioned above with the characterizing features of claim 1.
    A device suitable for this purpose has the features of claim 7.
    Further preferred embodiments of the method will become apparent from the dependent claims as well as preferred embodiments of the inventive device of the dependent claims which relate directly or indirectly to the independent device claim.
    Hereinafter, the inventive method will be explained with reference to the accompanying drawings, as well as an exemplary embodiment of a suitable device for carrying out the inventive method.

    Only for a better understanding of the subsequent inventive mounting method, the previously known automatic assembly of components for the second module is briefly explained.
    In Fig. 1, a tensile tenon 10 is shown as a first component of the second assembly to be formed. This traction pin 10 has an annular wall 11 with an external thread 12 mounted thereon. The distal end of this annular wall 11 is closed by a cover surface 13, not shown here, indicated by an arrow. In the top surface 13 are two passage openings, provided by the two molded bushing 14, 15, wherein the bushing with the larger diameter forms the respiratory nozzle 14, while the kinked extending esophageal neck 15 has a smaller diameter. In the proximal, visible end of the pull pin 10, these two sockets 14, 15 are visible. Between the two grommets 14 and 15, a small, rectangular in cross section through opening 16 is present, which opens in the region of a rectangular receiving recess 17.
    In a second step, the tension pin 10 is now screwed into a union nut 20. This union nut 20 has an internal thread not visible here, which is suitable for the external thread 12 of the pull pin 10. The distal end of the cap nut has a plurality of circumferentially distributed spring tongues 21, which have directed towards the center locking ribs 22.
    In a next step, a so-called air connector 30 is now inserted into the pull pin 10, wherein this air connector 30 has a round disc at the proximal end of a connecting piece for the supraglottic tube is present, while at the distal end of a respiratory tube section is formed, the pierces the respiratory tube 14 on the pull pin 10 in the assembled state and protrudes from this. An esophageal tube section which is likewise present on the distal side engages in the assembled state in a sealing manner into the esophageal stub 15 of the pull pin 10. The circular disc of the air connection part 30 is encompassed by the spring tongues 21 in the mounted state and the locking ribs 22 hold this disc within the union nut 20. This assembly step takes place by purely translational linear assembly of the air connection part 30 in the union nut 20th
    4 shows the retracted in another station of a mounting device tension member 40. This tension member consists essentially of an elastic rod 41 with a rectangular cross-section. The elastic rod 41 has at the distal end of an anchoring plate 42. In the fully inserted state of this anchoring plate is on the distal side of the visible in Fig. 4 top surface 13 of the pull pin 10 at. At the proximal end of the elastic rod 41 has a thickened anchoring head 43. The anchoring plate 42 can be held in position in the mounting device during the next steps, but it is also possible to provide the anchoring plate 42 with locking means, the complete insertion of the pulling member 40 in the traction pin 10 irreversibly locks in this. In Fig. 4, the tension member 40 is shown mounted in the tension pin 10.
    On the tension member 40, the link chain 50 is now postponed. The link chain 50 has a first long, rigid member 51 on which a continuous dorsal wall 53 then follow the other, much shorter members 52 of the link chain 50. A ventral wall 54 is interrupted between each two adjacent members 51, 52. Below the dorsal wall 53 extends over the entire length of the link chain 50, a channel which serves as a guide channel 55 for the tension member 40. Lateral bridges 56 engage over this channel 55 to guide the tension member 40 in the channel 55 secured. The proximal end member 52 has latching means 57 which is capable of irreversibly holding the anchoring head 43 as soon as the pulling member 40 is fully inserted.
    In principle, Fig. 5 could represent the fully assembled position of the second assembly. In fact, however, the link chain 50, as shown in FIG. 6, still curved so that the members 51, 52 dorsally closer together and thus the tension member 40 further protrudes into the proximal end member of the link chain 50 and then only the anchoring head 43 irreversible is anchored. After that, it is quite possible to bring the link chain back into the stretched state, as shown in FIG. 5. This is dependent on how the inventive method, which is described below, is performed. It is both possible to collide both assemblies in the straight-line straight course or to insert the second assembly in a curved running shape in the straight first assembly or what is particularly preferred to push both assemblies equally curved running into each other.
    The first assembly may, as already mentioned, either consist of two pre-assembled parts or as shown here in Fig. 7 can be made in one piece. This first assembly consists of a larynx mask head 1 and a supraglottic tube 2 integrally formed thereon. The embodiment of the laryngeal mask head 1 shown here corresponds to an embodiment as described in document WO 2013/182 480, while the supraglottic tube 2 shown in document WO 2013/182 457 is described.
    With reference to FIGS. 1-7 has been described so far as the first assembly was assembled, this being done on typical rotary indexing systems. For the following description of the mounting method according to the invention, the laryngeal mask head 1 with the supraglottic tube 2 is now referred to as the first assembly A, while the second assembly B has been formed from five parts, namely a tenon 10, union nut 20, air connection part 30, tension member 40 and link chain 50 is.
    The mounting device according to the invention also consists essentially of two parts of the device, namely a stationary device part 100 and a movable device part 200. This is shown in the drawing Fig. 11 in a simplified representation. This simplified illustration shows in principle only these two parts wherein the stationary part 100 of the device is fixedly held on a tripod, while the second, movable member 200 is rotatably guided on a frame 201 about a pivot axis 202. All drive systems, control systems and electrical and hydraulic feeders were deliberately omitted.
    In Fig. 11, a solution is shown, in which the supraglottic tube is curved during the merger of the two assemblies A and B. Here, two mold parts are shown, which serve the supraglottic tube 2 by means of two mold parts 102 and 103 to keep in a curved shape. In the two mold parts 102 and 103 corresponding recesses are formed in which the tube 2 can be kept clamped. This curved shape of the tube 2 during assembly is preferred since this results in lower frictional forces of the link chain 50 in the guide lumen of the tube 2 during assembly.
    In Fig. 8, the actual clamping member 104 is shown with the first assembly A held during assembly. The clamping part 104 has a housing 105 in which two counter-driven slide 106 are hydraulically or electromechanically operated out and on each of which a holding jaws 107 is guided. These two holding jaws 107 then surround the tube 2 of the first assembly A.
    Much more complex is the movable part of the mounting device 200. This movable part 200 has two side cheeks 201, wherein a pivot arm 202 engages one of the two side cheeks 201. The side cheeks 201 are provided along their lower edge with a curved course, which corresponds formally to the curvature of the link chain 50, which is to be inserted into the supraglottic tube 2. A plurality of support beams 203 are mounted along this lower edge perpendicularly projecting therefrom. On a first, generally slightly wider support beam 203, a holding device 204 is mounted. This holding device has two driven, counter-moving retaining cheeks 205. The retaining cheeks 205 move linearly towards each other or run linearly apart. The retaining cheeks 205 hold the second assembly B in the region of the connection piece 31 of the air connection part 30. On the four other support beams 203 shown, two pivotable clamping jaws 206 movable toward each other are mounted in a pivotable manner. The pairs of clamping jaws 206, which can be pivoted towards one another in pairs, enable the link chain 50 to be held over a large part of the entire course. In Fig. 10, the jaws 6 are shown in the closed state. Only the foremost jaw, which is closest to the retaining cheeks, is already open again. This foremost jaw serves only to keep during the closing of the jaws 206, the foremost, longest link of the link chain 50 exactly in position so as to secure the course of the other members of the link chain 50 in the correct position, so that the other jaws 206 the Can detect link chain in its correct course. The proximal foremost chain link projects out of the foremost clamping jaw 206 in the proximal direction. This position is now shown in FIG. Here, the second side cheek 201 is also shown while it is omitted in Figs. 9 and 10 for the sake of clarity. The already described FIG. 11 is now skipped to explain the procedural steps for assembling the two assemblies A and B with reference to FIGS. 12-14.
    In the insertion direction or in the proximal direction vorderst lying member of the link chain 50 is shown in Fig. 11 in the not yet introduced state. It can be seen that the two straight edges of the side cheeks 201 run horizontally one and vertically the other side. In FIG. 12, the movable part 200 is now pivoted through a first angle until the clamping jaw 206 arranged in the proximal direction rests virtually up against the distal end of the tube 2 of the assembly A. Here, the pivotal movement of the movable member 200 is stopped and the foremost jaw 206 is now opened.
    Thereafter, the movable part 200 of the mounting device again moves in a pivoting movement until the subsequent clamping jaw 206 in turn abuts practically approximately at the distal end of the tube 2. This situation is shown in FIG. The next, now practically applied jaw 206 is now opened, the pivotal movement of the pivot arm 202 with the two connected side walls 201 and the support beam 203 in turn moved by an angle and stopped, in the position as shown in FIG. 14 now.
    Now the last still closed clamp is opened and the pivoting movement of the movable member 200 continues until the longest straight edge in the side cheek 201 extends in the horizontal direction and the last link of the link chain 50 is exactly aligned with the straight running portion of the tube 2 or the link chain is completely inserted into the tube 2.
    Since the supraglottic tube is held curved extending, thereby the entire link chain 50 can be completely inserted into the tube only by the successive pivotal movement of the movable part 200. This is another advantage preferred solution with curved course of the link chain 50.
    The entire assembly of all parts to a finished laryngeal mask can now be realized in less than 10 seconds. The assembly of the second module can be realized in a rotary indexing machine having a rotary table with several stations arranged around it in about 4-5 seconds. The inventive method for assembling the first and second modules A and B requires about 8-10 seconds in a single station. Looking at two such mounting devices, the assemblies can be assembled at the same speed as the second assembly needed for assembly. This is almost 10 times faster than a handmade version. In addition, the stepwise assembly always leads to the fact that the highly elastic TPE of Larynxmaskenkopfes and the tube can relax during the short holding times, so that virtually no jamming of the second assembly B in the guide lumen of the tube 2 of the assembly A occurs during assembly.
