[0051] FIG. 5a shows a standard endoscope;

[0052] FIGS. 5b and 5c show the standard endoscope from FIG. 5a, on which an intubation aid according to the second aspect is arranged;

[0053] FIG. 6 shows the intubation aid according to the second aspect in a schematic sectional side view;

[0054] FIG. 7 shows a schematic sectional side view of the intubation aid according to the second aspect.

[0055] An inventive intubation aid is generally denoted with reference number 10 in FIG. 1. The intubation aid 10 comprises an elongate main part 12 which has a handle 14 at its one end and a free end 16 at its other end. In FIG. 1, the main part 12 is designed to be bent in a first region 18 such that a segment of the main part 12 arranged between the free end 16 and the first region 18 can be deflected downward by up to an angle α. Furthermore, the main part 12 has a second region 20, which is designed to be bent such that the free end 16 can be deflected relative to a segment between the first region 18 and the second region 20 by an angle up to 13 which extends in the same direction as the angle α, or, in the opposite direction, up to an angle γ.

[0056] Arranged between the free end 16 and the second region 20 of the main part 12 is a tapering segment 22, across which an outer diameter of the main part 12 in the segment of the second region 20 gradually decreases to an outer diameter of the main part 12 in the segment of the free end 16.

[0057] At its end opposite the free end 16, the elongate main part 12 has a positioning device 24, designed here as a cone 24. Arranged in a segment between the cone 24 and the handle 14 is an operating device 26, which comprises a first operating element 28 and a second operating element 30. The first operating element 28 is coupled to the first region 18 via a cable pull, such as a Bowden cable, for example, such that an actuation of the first operating element 28 by an operator in a corresponding direction causes a deflection of the first region 18 in accordance with the amount input on the first operating element 28. The second operating element 30 is coupled to the second region 20 in an analogous manner.

[0058] The first operating element 28 is connected to a latching device, so that a set deflection of the first region 18 can be locked using the operating element 28 itself or, for example, using a corresponding segment of the handle 14.

[0059] As can be seen in FIG. 1, the handle 14 includes a single-finger receiving element 32, which is designed in particular to receive an operator's index finger, and which is arranged on the same side of the intubation aid 10 on which the first region can be deflected by up to the angle α and the second region can be deflected by up to the angle ß, and a two-finger receiving element 34, which is designed to receive in particular the middle finger and the ring finger of the operator.

[0060] FIG. 2 shows a view of the free end 16 of the inventive intubation aid 10 from FIG. 1, as indicated by the arrow II in FIG. 1. It can be seen here that a channel 36 is arranged in the main part 12 and is formed along the longitudinal extension of the main part 12. The channel 36 is not arranged completely within the main part 12, but extends along its length, in the embodiment shown here from the free end 16 to the cone 24, via an interruption in the circumferential direction of the channel 36 with an outside of the main part 12 in fluid communication. This creates a gap 38 which, in this embodiment, extends from the free end 16 to the cone of the positioning device 24, wherein the channel 36 is accessible via this gap 38, for example for cleaning. However, as described above, it is also possible for the channel 36 to terminate at the tapering segment 22 of the main part 12.

[0061] The channel 36 is connected at its end opposite the free end 16 to an interface 40 (see FIG. 1) which is designed to be connected to a suction device and/or to a gas source and/or to a virus/bacteria filter or the like. Under the action of the suction device connected to the interface 40, aerosol can be suctioned out of the mouth/pharynx, larynx, and trachea of the patient when the patient is being intubated, so that free escape of the potentially virus-laden aerosol into an environment can be prevented. The channel 36 can also be used to introduce, for example, oxygen, into the patient from a gas source via the interface 40.

[0062] Furthermore, it can also be seen in FIG. 2 that an imaging unit 42 designed for recording imaging information in surroundings of the free end 16 of the intubation aid 10, as well as an illumination device 44, embodied here as two LED light sources 44, is embodied at the free end 16 of the main part 12.

[0063] FIG. 3 shows the intubation aid 10 from FIG. 1, wherein a ventilation tube 46 has been fitted over the main part 12. The ventilation tube 46 has a collar 48 which, after the tube 46 has been used in a patient and the intubation guide 10 has been removed from the tube 46 and the patient, functions as an interface to a ventilation device. In the region of the collar 48, the tube 46 is held by the cone 24, which acts as a holding device here, in a friction fit against a specific force that displaces the tube 46 from the main part 12 (to the right in FIG. 3). The ventilation tube 46 further has an expandable region 50 which can be filled with a gas, for example, in order to seal off an air space connected to the lungs from an air space connected to the mouth once the tube 46 is at its desired location in the patient.

[0064] The intubation aid 10 comprises a communication module 52 designed to communicate wirelessly 54 and/or in a wired connection 56 with an external unit 58, which in this case is a portable monitor, designed to display the image data recorded using the imaging unit 42.

[0065] FIG. 4 shows that a monitor 60 can be arranged directly on the intubation aid 10, as an alternative or in addition to coupling the intubation aid 10 to an external monitor according to FIG. 3, on a segment on which in particular the operating unit 26 is arranged. Of course, the intubation aid 10 can also be embodied such that it can communicate both with the monitor 58 (FIG. 3) and with the monitor 60 (FIG. 4) at the same time.

[0066] A standard endoscope 200 is shown in FIGS. 5a to 5c and has a corresponding bending mechanism at its free end 216, wherein an intubation aid 100 according to a second aspect of the present invention is attached in FIGS. 5b and 5c (of which here only one main part 112 is shown for the sake of clarity). Elements of the intubation aid 100 according to the second aspect that are similar to the intubation aid 10 according to the first aspect are provided with the same reference numbers, but increased by 100.

[0067] FIGS. 5b and 5c show two main parts 112, which each have different prebends which equate to a curvature functionality of the “first region” of the first aspect of this invention.

[0068] FIG. 6 shows a schematic side view of the intubation aid 100. It can be seen that the intubation aid 100 is fitted over the endoscope 200 until a connecting segment 162, or more precisely, in the embodiment shown, a first engagement segment 164 (see FIG. 7), engages with the endoscope 200.

[0069] A main part 112 is attached to the connecting segment 162 via a retaining clip 166 and has a tapering segment 122 at its end opposing the retaining clip 166. A ventilation tube 146 is fitted over the main part 112 such that it is held on the connecting segment 162 via a suitable second engagement segment 168 (see FIG. 7) against a releasing force which acts on the intubation aid 100 in a direction opposite to the direction in which the ventilation tube 164 is fitted on.

[0070] It can also be seen in FIG. 6 that a distal segment of the endoscope 200 is guided through receiving segments 170 and 172, respectively, of the connecting segment 162 and of the tapering segment 122.

[0071] A schematic side sectional view of the intubation aid 100 is shown in FIG. 7. As can be seen here, in the interior of the tube 146 the fitted tube 146 forms a channel 136 which can be used to suction off aerosol using a suction device connected to the interface 140 of the connecting segment 162. Going back to FIG. 6, it can be seen that in addition to the interface 140, which is connected to a virus/bacteria filter 174, an interface 176 via which oxygen can be introduced into the channel 136 is embodied separate from the interface 140 on the connecting segment 162.
