Abstract

Embodiments of a laryngoscope blade for being removable mounted to a laryngoscope handle. In some embodiments, the laryngoscope blade may include a blade portion including a proximal end and a distal end provided with an optic window; a base portion including two base halves mounted to each other and to the proximal end of the blade portion such that the proximal end of the blade portion is located between each base half; and an optic light pipe including a proximal end disposed between the two base halves and a distal end extending through the optic window.

Claims (30)

1. A laryngoscope blade, comprising:

a blade portion having a proximal end and an arcuate distal end, the proximal end of the blade portion having a contoured optic channel, the distal end of the blade portion having an optic window;

a first base half made of a first material and coupled to a second base half made of a second material such that the proximal end is between the first and second base halves, the second material being more resilient than the first material; and

an optic light pipe having a contoured proximal end and a distal end, the contoured proximal end of the optic light pipe configured to fit in the contoured optic channel, the distal end of the optic light pipe configured to fit in the optic window.

2. The laryngoscope blade of claim 1 , wherein the first base half comprises a rigid hook defining an inclined opening.

3. The laryngoscope blade of claim 1 , wherein the first base half comprises a cantilever ball detent.

4. The laryngoscope blade of claim 1 , wherein the first base half comprises a curved optic cover configured to cover the contoured proximal end of the optic light pipe on three sides.

5. The laryngoscope blade of claim 1 , wherein the first base half comprises a plurality of inwardly extending sockets.

6. The laryngoscope blade of claim 1 , wherein the second base half comprises a resilient cantilever latch pin defining an inclined opening.

7. The laryngoscope blade of claim 1 , wherein the second base half comprises a plurality of outwardly extending pins.

8. The laryngoscope blade of claim 1 , wherein the blade portion comprises a medial wall.

9. The laryngoscope blade of claim 8 , wherein the optic window is formed in the medial wall.

10. The laryngoscope blade of claim 8 , wherein the blade portion comprises an attachment hole in the medial wall.

11. The laryngoscope blade of claim 1 , wherein the distal end of the blade portion comprises a mounting tang.

12. The laryngoscope blade of claim 1 , wherein the first base half comprises a rigid hook defining a first inclined opening having a first width, the second base half comprises a resilient cantilever latch pin defining a second inclined opening having a second width, and the first width is different than the second width.

13. A laryngoscope blade, comprising:

a blade portion having a proximal end and an arcuate distal end, the proximal end of the blade portion having a contoured optic channel, the distal end of the blade portion having an optic window;

a first base half coupled to a second base half such that the proximal end is between inner facing surfaces of the first and second base halves, the second base half defining a straight optic channel; and

an optic light pipe having a contoured proximal end and a distal end, the contoured proximal end of the optic light pipe configured to fit in the contoured optic channel, the distal end of the optic light pipe configured to fit in the optic window, the optic light pipe configured to fit between the inner facing surfaces of the first and second base halves and in the straight optic channel.

14. The laryngoscope blade of claim 13 , wherein the first base half comprises a rigid hook defining an inclined opening.

15. The laryngoscope blade of claim 13 , wherein the first base half comprises a cantilever ball detent.

16. The laryngoscope blade of claim 13 , wherein the first base half comprises a curved optic cover configured to cover the contoured proximal end of the optic light pipe on three sides.

17. The laryngoscope blade of claim 13 , wherein the second base half comprises a resilient cantilever latch pin defining an inclined opening.

18. The laryngoscope blade of claim 17 , wherein the optic window is formed in a medial wall of the blade portion.

19. A laryngoscope blade, comprising:

a blade portion having a flange extending from a medial wall, a proximal end, and an arcuate distal end, the proximal end of the blade portion having a contoured optic channel, the distal end of the blade portion having an optic window;

a first base half made of a first material and coupled to a second base half made of a second material such that the proximal end is between the first and second base halves, the first base half including an optic cover, the first material being more rigid than the second material, the second material being more resilient than the first material; and

an optic light pipe having a contoured proximal end and a distal end, the contoured proximal end of the optic light pipe configured to fit in the contoured optic channel, the distal end of the optic light pipe configured to fit in the optic window,

wherein the optic cover covers the contoured proximal end of the optic light pipe on three sides and the medial wall covers a fourth side of the contoured proximal end of the optic light pipe.

20. The laryngoscope blade of claim 19 , wherein the first base half comprises a rigid hook defining a first inclined opening having a first width, the second base half comprises a resilient cantilever latch pin defining a second inclined opening having a second width, and the first width is different than the second width.
