Video laryngoscope with disposable blade
View Patent ↗An intubation instrument for intubating a patient's trachea including an imager module having a base unit with a finger loop and a longitudinal member attached to the distal end of the base unit, as well as a blade having a handle that is hollow and mates with the outer surface of the longitudinal member forming a male-female connection, the distal end of the blade projecting laterally therefrom, the distal end of the blade being insertable into a human during intubation.
1. An intubation instrument comprising:
an imager module, the imager module including
a base unit having a proximal end and a distal end, the proximal end of the base unit having a finger loop, the base unit further including a hollow portion having a loop, the hollow portion adapted to receive electronic wiring, and
a longitudinal member, the longitudinal member attached to the distal end of the base unit and projecting longitudinally away from the distal end of the base unit; and
a blade, the blade having a proximal end and a distal end, the proximal end forming a handle that is hollow and that mates with an outer surface of the longitudinal member forming a male-female connection, and the distal end of the blade projecting laterally therefrom, the distal end of the blade being insertable into a human during intubation.
2. The intubation instrument of claim 1 , wherein the base unit includes a flange at the distal end of the base unit, the flange on the base unit abutting against a flange in the proximal end of the blade.
3. The intubation instrument of claim 1 , wherein the longitudinal member includes a ball plunger on an outside surface of the longitudinal member.
4. The intubation instrument of claim 3 , wherein the blade includes a ball detent on an inside surface of the handle of the blade, the ball detent adapted to interact with the ball plunger of the longitudinal member so that the longitudinal member and blade are connected with each other during use of the intubation instrument.
5. The intubation instrument of claim 4 , wherein when in use, the ball plunger of the longitudinal member locks into the ball detent on the inside surface of the handle of the blade to lock the blade to the longitudinal member.
6. The intubation instrument of claim 1 , further comprising electronic wiring, the electronic wiring containing a camera at its distal end.
7. The intubation instrument of claim 6 , wherein the imager module and the blade are adapted to receive the electronic wiring, the electronic wiring passing through the imager module and the blade.
8. The intubation instrument of claim 6 , wherein the electronic wiring is connected to a display for displaying images received by the camera.
9. The intubation instrument of claim 8 , wherein the electronic wiring is partially contained within the distal end of the blade.
10. The intubation instrument of claim 1 , wherein the blade includes a guide located within the handle of the blade, the guide including a channel.
11. The intubation instrument of claim 10 , wherein the channel is adapted to receive electronic wiring, the electronic wiring containing a camera at its distal end.
12. The intubation instrument of claim 11 , wherein the channel in the blade is sandblasted for easier insertion and removal of the electronic wiring.
13. The intubation instrument of claim 1 , wherein the longitudinal member includes electronics to control the imager module.
14. The intubation instrument of claim 1 , wherein said blade is disposable.
15. The intubation instrument of claim 1 , wherein said blade is made of plastic or a hard polymer material.
16. The intubation instrument of claim 1 , wherein the intubation instrument is a video laryngoscope.
17. The intubation instrument of claim 1 , wherein the imager module is separable from the blade, wherein the imager module is disinfected after being used and the blade is disposed of after use.
18. The intubation instrument of claim 1 , wherein the electronic wiring is flexible.
19. The intubation instrument of claim 1 , wherein the blade includes a lens at its distal end.
20. An intubation instrument comprising:
an imager module, the imager module including
a base unit having a proximal end and a distal end, the proximal end of the base unit having a finger loop, the base unit further including a hollow portion having a loop, the hollow portion adapted to receive electronic wiring, and
a longitudinal member, the longitudinal member attached to the distal end of the base unit and projecting longitudinally away from the distal end of the base unit, the longitudinal member having a ball plunger on an outside surface of the longitudinal member; and
a blade, the blade having a proximal end and a distal end, the proximal end forming a handle that is hollow and that mates with an outer surface of the longitudinal member forming a male-female connection such that a portion of the longitudinal member is located within the blade, and the distal end of the blade projecting laterally therefrom, the distal end of the blade being insertable into a human during intubation, the blade including a ball detent on an inside surface of the handle of the blade, the ball detent adapted to interact with the ball plunger of the longitudinal member so that the longitudinal member and the blade are connected with each other during use of the intubation instrument,
wherein when in use, the ball plunger of the longitudinal member locks into the ball detent on the inside surface of the handle of the blade to lock the handle to the longitudinal member and handle.
21. The intubation instrument of claim 20 , wherein the blade is disposable blade.
22. The intubation instrument of claim 20 , wherein the intubation instrument is a laryngoscope.
