Abstract

The invention relates to a device for introducing an intubation tube into the trachea. The inventive device comprises a shaft, a receiving element arranged at the distal end of said shaft to which a proximal end of an intubation tube can be mounted and a coupling arranged at the proximal end of the shaft for coupling an endoscope thereto.

Claims

1. An apparatus for introducing an intubation tube into a trachea, comprising:

a shaft having,

a plurality of interlocked sections, each having an interlocking stop for inhibiting the sections from being separated from one another,

a first coupler arranged at a distal end of said shaft, said first coupler provided for coupling to an intubation tube; and

a second coupler arranged at a proximal end of said shaft for coupling to an endoscope, and

wherein a length of said shaft is variable such that the intubation tube and the endoscope are axially movable relative to each other.

2. The apparatus of claim 1, wherein said shaft is configured to be telescopic.

3. The apparatus of claim 1, wherein said shaft is tubular.

4. The apparatus of claim 3, wherein said shaft is configured of several telescopic tubes shiftable within one another.

5. The apparatus of claim 1, wherein a gas connector is arranged at said proximal end of said shaft, which gas connector communicating with an interior of said shaft.

6. The apparatus of claim 1, wherein a handle is arranged at said distal end of said shaft, through which handle said apparatus can be handled.

7. The apparatus of claim 1, wherein said first coupler is configured as a tube, onto which a proximal end of said intubation tube can be slid.

8. The apparatus of claim 7, wherein said tube is configured to be slightly conical.

9. The apparatus of claim 1, wherein said first coupler is configured as a hollow tube into which hollow tube a proximal end of said intubation tube can be inserted.

10. The apparatus of claim 9, wherein the hollow tube is configured to be slightly conical.

11. The apparatus of claim 1, wherein said shaft is configured hollow allowing to pass a shaft of an endoscope through said apparatus from a proximal end thereof.

12. The apparatus of claim 1, wherein said shaft is configured such that a gas can be passed through said shaft, also when an endoscope is inserted into said shaft.

13. The apparatus of claim 1, wherein a slot is provided over an entire length of said apparatus in order to place said apparatus laterally onto a shaft of an endoscope.

14. The apparatus of claim 1, wherein said second coupler is designed to fixedly attach the shaft to an endoscope attached to said second coupler.

15. The apparatus of claim 1, wherein said second coupler comprises a locking mechanism for locking said second coupler to an endoscope.

16. The apparatus of claim 15, wherein said locking mechanism comprises at least one ball catch, and wherein said endoscope is configured with at least one recess engaging with said ball catch.

17. The apparatus of claim 16, wherein said recess for engaging with said ball catch is formed as a circumferential groove.

18. The apparatus of claim 1, wherein said second coupler is designed with a union nut connection for connecting said second coupler to said endoscope.

19. The apparatus of claim 1, wherein said second coupler is designed as a bayonet for connecting to said endoscope having a respective bayonet.

20. The apparatus of claim 1, having an intubation tube attached to said distal end of said shaft and being coupled to an endoscope at a proximal end of said shaft.

21. The apparatus of claim 1, wherein said shaft is integrally formed with an endoscope.

22. The apparatus of claim 1, wherein said endoscope for coupling to said second coupler having a shaft selected from the group consisting of rigid shafts, semi-flexible shafts and flexible shafts.

23. The apparatus of claim 22, wherein said endoscope is provided with a camera.

24. A coupling apparatus for introducing an intubation tube into a trachea, comprising:

an intubation tube;

an endoscope;

a shaft member of variable length, having a proximal and a distal end;

a first coupler, provided at the distal end of the shaft member, for connecting the shaft member to the intubation tube; and

a second coupler, provided at the proximal end of the shaft member, for connecting the shaft member to the endoscope, such that the endoscope extends through the shaft member and into the intubation tube;

wherein the shaft member of variable length has a plurality of slideable shaft sections, each section having an interlocking stop for inhibiting the sections from being separated from one another such that the endoscope is adjustable between a maximum insertion position when the shaft is fully compressed and a minimum insertion position when the shaft is fully extended.
