DETAILED DESCRIPTION OF THE INVENTION

(8) Referring to the drawings and initially to FIGS. 1-5, an image type laryngoscope apparatus in accordance with the preferred embodiment of the present invention comprises a laryngoscope 3, a fastening device 1 and an image device 2.

(9) The laryngoscope 3 includes a handle 31 and a tongue pressing plate 32 connected with a lower end of the handle 31.

(10) The fastening device 1 includes two symmetric clamping members 11, a connecting rod 13 and a driving lever 14. Each of the clamping members 11 is provided with an arcuate groove 12 abutting the handle 31 of the laryngoscope 3 so that the handle 31 of the laryngoscope 3 has an upper end clamped between the arcuate grooves 12 of the clamping members 11. Preferably, the arcuate groove 12 of each of the clamping members 11 is provided with an antiskid pad 121. Each of the clamping members 11 has a first end and a second end. The first end of each of the clamping members 11 is provided with a pivot end 111, and the pivot ends 111 of the clamping members 11 are pivotally connected with each other. The second end of one of the clamping members 11 is provided with an elongate slot 15. The connecting rod 13 is inserted into the elongate slot 15. The connecting rod 13 has a first end pivotally connected with the second end of the other one of the clamping members 11. The driving lever 14 is pivotally connected with a second end of the connecting rod 13. Preferably, the driving lever 14 has a shape corresponding to that of each of the clamping members 11 so that the driving lever 14 can abut one of the clamping members 11.

(11) The image device 2 includes a signal transmitting unit 21, a guide pipe 22, a camera lens 23 and a monitor 24. The signal transmitting unit 21 is mounted on one of the clamping members 11. The guide pipe 22 is connected with the signal transmitting unit 21 and has an interior containing a signal line. The guide pipe 22 is retained by a retainer 221 which is secured on the tongue pressing plate 32 of the laryngoscope 3. The camera lens 23 is mounted on a front end of the guide pipe 22 and is located at a front end of the tongue pressing plate 32 of the laryngoscope 3. The camera lens 23 has a periphery provided with a plurality of light emitting members 231 (FIG. 3) to provide a light source. The monitor 24 is connected with the signal transmitting unit 21 by a connecting unit 211 in a wire manner.

(12) In practice, the arcuate groove 12 of each of the clamping members 11 abuts the handle 31 of the laryngoscope 3. Then, the connecting rod 13 is pivoted and inserted into the elongate slot 15. Then, the driving lever 14 is pivoted to drive the connecting rod 13 and to force the clamping members 11 to move toward each other so as to shorten the distance between the arcuate grooves 12 of the clamping members 11, so that the clamping members 11 are closely fitted onto the handle 31 of the laryngoscope 3. Thus, the handle 31 of the laryngoscope 3 is clamped between the clamping members 11 so that the image device 2 is attached to the laryngoscope 3 by the fastening device 1. At this time, the guide pipe 22 extends to the tongue pressing plate 32 and is secured on the tongue pressing plate 32 by the retainer 221, and the camera lens 23 is located at the front end of the tongue pressing plate 32.

(13) In operation, referring to FIG. 6 with reference to FIGS. 1-5, after the camera lens 23 is started, the image signals taken by the camera lens 23 are delivered to the signal transmitting unit 21 and are then transmitted to the monitor 24 in a wire transmission manner so that the operator can clearly inspect the condition of a patient's throat by the image signals.

(14) Referring to FIG. 7, the signal transmitting unit 21 transmits the image signals to a mobile device 4 in a wireless transmission manner by bluetooth or WiFi. Preferably, the mobile device 4 is a monitor, a tablet computer or a cell phone.

(15) Accordingly, the image device 2 is attached to the laryngoscope 3 by the fastening device 1, and the signal transmitting unit 21 transmits the image signals to the monitor 24 in a wire transmission manner or to the mobile device 4 in a wireless transmission manner, so that the operator can clearly inspect the instant condition of a patient's throat by the image signals. In addition, the image device 2 is attached to the laryngoscope 3 which has a conventional structure so that the operator can operate the laryngoscope 3 instantly without having to change his/her operational customs or habits, and without having to learn new operational methods and skills, thereby facilitating the operator operating the laryngoscope 3, and thereby saving the cost.

(16) Although the invention has been explained in relation to its preferred embodiment(s) as mentioned above, it is to be understood that many other possible modifications and variations can be made without departing from the scope of the present invention. It is, therefore, contemplated that the appended claim or claims will cover such modifications and variations that fall within the true scope of the invention.
