Laryngoscope with a movable image-capturing unit

1. A laryngoscope comprising:

a handgrip;

a blade having a connected end and an opposite end, with the connected end of the blade connected to the handgrip, with the blade having a slide track;

an image-capturing unit for capturing an image, said image-capturing unit having a free end and being movably installed in the slide track of the blade to adjust positioning of the image-capturing unit in a slide direction along the slide track and relative to the blade in use between a first spot and a second spot, with the free end located at a lesser spacing in the slide direction from the opposite end in the second spot than in the first spot; and

an adjustment piece driving movement of the image-capturing unit relative to the blade in use, wherein the adjustment piece comprises a pushing part and a supporting part, said pushing part having a front end and a rear end, with the pushing part being slideably mounted on the blade, said supporting part having a fixed end connected to the handgrip and a joint end pivotally mounted to the rear end of the pushing part, said front end of the pushing part pushing and pulling the image-capturing unit between the first and second spots.

2. The laryngoscope as claimed in claim 1 , wherein the image captured by the image-capturing unit is transmitted wirelessly.

3. The laryngoscope as claimed in claim 1 , further comprising a display for displaying the image, said display being installed on the handgrip.

4. The laryngoscope as claimed in claim 1 , wherein the handgrip further comprises a power supply providing electricity to the image-capturing unit.

5. The laryngoscope as claimed in claim 1 , wherein the image-capturing unit includes an illumination unit, with the illumination unit moving with movement of the image-capturing device.

6. The laryngoscope as claimed in claim 5 , wherein the image captured by the image-capturing unit is transmitted wirelessly.

7. The laryngoscope as claimed in claim 5 , further comprising a display for displaying the image, said display being installed on the handgrip.

8. The laryngoscope as claimed in claim 5 , wherein the illumination unit is an LED light bulb.

9. The laryngoscope as claimed in claim 1 , further comprising an endotracheal tube having a side aperture, with the endotracheal tube extending adjacent to the blade, wherein the image-capturing unit penetrates through the side aperture on the endotracheal tube, with the endotracheal tube sleeved on the image-capturing unit between the free end and the side aperture, with adjusting positioning of the image-capturing unit relative to the blade moving the endotracheal tube relative to the blade.

10. A laryngoscope comprising:

a handgrip;

a blade connected to the handgrip;

an image-capturing unit for capturing an image, said image-capturing unit being movably secured on the blade to adjust positioning of the image-capturing unit relative to the blade in use; and

an endotracheal tube having a side aperture, with the endotracheal tube extending adjacent to the blade, wherein the image-capturing unit penetrates through the side aperture on the endotracheal tube, with the endotracheal tube sleeved on the image-capturing unit between the free end and the side aperture, with adjusting positioning of the image-capturing unit relative to the blade moving the endotracheal tube relative to the blade.

11. The laryngoscope as claimed in claim 10 , further comprising an adjustment piece driving movement of the image-capturing unit relative to the blade in use.

12. The laryngoscope as claimed in claim 11 , further comprising a display for displaying the image, said display being installed on the handgrip.

13. The laryngoscope as claimed in claim 12 , wherein the adjustment piece comprises a pushing part and a supporting part, said pushing part having a front end and a rear end, with the pushing part being slideably mounted on the blade, said supporting part having a fixed end connected to the handgrip and a joint end pivotally mounted to the rear end of the pushing part, said front end of the pushing part actuating the image-capturing unit.

14. The laryngoscope as claimed in claim 13 , wherein the image captured by the image-capturing unit is transmitted wirelessly.

15. The laryngoscope as claimed in claim 13 , wherein the handgrip further comprises a power supply providing electricity to the image-capturing unit.

16. The laryngoscope as claimed in claim 13 , wherein the image-capturing unit includes an illumination unit, with the illumination unit moving with movement of the image-capturing device.

17. The laryngoscope as claimed in claim 16 , wherein the illumination unit is an LED light bulb.
