Background
Bronchoscopes are used to check the position of the double lumen tube and a monitor is used to share the image. However, such monitors are expensive and require a long set-up time. We speculated that a bronchoscope with a small monitor like those included with video laryngoscopes could be very useful. We thus created the i-NTER LENSTM (Micronet Corp.) device to serve this purpose. We also made an application that improves the performance of the i-NTER LENSTM (Micronet Corp.), named the EndoscopeTM (Micronet Corp. )   
Description
The i-NTER LENSTM (Micronet Corp.) is an optical device with six internal lenses that serve to make the image clearer. It weighs 210 g and is 720 mm long. A smartphone, the i-NTER LENSTM and a bronchoscope can be connected very easily. The EndoscopeTM (Micronet Corp.) application has many features. The operator can take pictures by moving his/her hand in front of the smartphone without touching it, and can erase the picture by breathing on the smartphone. The application can change the brightness of the image, zoom the image, and invert the image. A smartphone is used as the bronchoscope monitor, and the image or movie taken by smartphone can be sent to another monitor in another country. The i-NTER LENSTM (Micronet Corp.) will thus be very useful in the fields of distance medicine and disaster medical care. 
Discussion
The i-NTER LENSTM and the EndoscopeTM are very useful, but there are four improvements. (1) We want to create a speech-recognition system that can be used to take the pictures and videos. Although pictures and videos can be taken by hand movements in front of the smartphone, the operator must release his/her hand from the bronchoscope to do so, and speech recognition would make that unnecessary. (2) Since bronchoscopes are fiberscopes, a honeycomb grid appears on every image taken. We want to erase the honeycomb grid that appears on the bronchoscope’s images. (3) We want to be able to save the images in the anesthesia chart. (4) Because the frame rate of video phones is low, we want to improve the quality of the video images.   
Learning points
We can prepare a bronchoscope faster by using the i-NTER LENSTM. We can save clearer images by using the EndoscopeTM. This device and application will be helpful in the fields of distance medicine and disaster medical care.
