The bar-shaped camera for capturing images is placed inside the endotracheal tube. The display device is electrically connected to the bar-shaped camera for displaying images captured by the bar-shaped camera. The guiding portion connected to the handle portion has a front end and a rear end. The rear end is connected to the handle portion, and the bar-shaped camera and the endotracheal tube are movably situated in the guiding portion. ## Claims ### Claim 1 A tracheal intubation device for placing an endotracheal tube in a trachea of a patient, the tracheal intubation device comprising: a bar-shaped camera placed inside an endotracheal tube for capturing an image; a handle portion; a display device connected with the handle portion and electrically connected to the bar-shaped camera for displaying the image captured by the bar-shaped camera; and a guiding portion connected to the handle portion comprising a front end, a rear end, a tongue piece, a barrier and a slot portion, wherein the tongue piece is extended form the rear end to the front end, the barrier is extended form the rear end to the front end and substantially perpendicular to the tongue piece, the slot portion comprises a main surface portion connected with the barrier and substantially paralleled to the tongue piece, the slot portion connected with the front end, thus a restricted passage is formed by the tongue piece, the slot portion and the barrier, an open passage is formed by the tongue piece and the barrier; whereby, the endotracheal tube and the bar-shaped camera are movably placed within the open passage and the restricted passage. ### Claim 2 (depends on 1) The tracheal intubation device as claimed in claim 1, wherein the tongue piece is extended form the rear end to the front end along a normal axis, the barrier is extended form the rear end to the front end along an oblique axis, and an included angle θ is formed by the normal axis and the oblique axis, wherein 10□□θ□40□. ### Claim 3 (depends on 2) The tracheal intubation device as claimed in claim 2, wherein the surface portion comprises a hook element situated at the rear end and paralleled to the barrier. ### Claim 4 (depends on 3) The tracheal intubation device as claimed in claim 3, wherein the rear end further comprises a connection portion and the guiding portion is detachably connected with the a handle portion via the connection portion. ### Claim 5 (depends on 4) The tracheal intubation device as claimed in claim 4, wherein the connection portion is an accommodation slot with an open end and a closed end, the barrier is diagonally extended form the closed end to the front end. ### Claim 6 (depends on 5) The tracheal intubation device as claimed in claim 5, wherein the tracheal intubation device further comprises a processor, a receiving module, a cell phone module, a memory, and a transmitting module, wherein the processor, the receiving module, the cell phone module, and the memory are separately electrically connected to the display device and the transmitting module is connected to the bar-shaped camera. ### Claim 7 (depends on 6) The tracheal intubation device as claimed in claim 6, wherein the display device and the handle portion are connected. ### Claim 8 (depends on 1) The tracheal intubation device as claimed in claim 1, wherein the surface portion comprises a hook element situated at the rear end and paralleled to the barrier. ### Claim 9 (depends on 8) The tracheal intubation device as claimed in claim 8, wherein the tongue piece is extended form the rear end to the front end along a normal axis, the barrier is extended form the rear end to the front end along an oblique axis, and an included angle θ is formed by the normal axis and the oblique axis, wherein 10□□θ□40□. ### Claim 10 (depends on 9) The tracheal intubation device as claimed in claim 9, wherein the tracheal intubation device further comprises a processor, a receiving module, a cell phone module, a memory, and a transmitting module, wherein the processor, the receiving module, the cell phone module, and the memory are separately electrically connected to the display device and the transmitting module is connected to the bar-shaped camera. ### Claim 11 (depends on 10) The tracheal intubation device as claimed in claim 10, wherein the display device and the handle portion are connected. ### Claim 12 (depends on 1) The tracheal intubation device as claimed in claim 1, wherein the slot portion comprises a restricted part connected with the surface portion and paralleled to the barrier. ### Claim 13 (depends on 12) The tracheal intubation device as claimed in claim 12, wherein the front end further comprises a protrusion part, and the slot portion does not extend to the protrusion part. ### Claim 14 (depends on 13) The tracheal intubation device as claimed in claim 13, wherein the tracheal intubation device further comprises an insertion unit mounted on the bar-shaped camera for placing inside the endotracheal tube. ### Claim 15 A tracheal intubation device for placing an endotracheal tube in a trachea of a patient, the tracheal intubation device comprising: a bar-shaped camera placed inside an endotracheal tube for capturing an image, wherein the bar-shaped camera is made of a rigid material that allows the bar-shaped camera to guide the direction of movement of the endotracheal tube while the endotracheal tube is moving; a handle portion; a display device electrically connected to the bar-shaped camera for displaying the image captured by the bar-shaped camera; and a guiding portion connected to the handle portion comprising a front end and a rear end, wherein the rear end of the guiding portion is connected to the handle portion, and the bar-shaped camera and the endotracheal tube are movably situated in the guiding portion; wherein the guiding portion comprises a tongue piece and a barrier; the tongue piece is substantially perpendicular to the barrier and the endotracheal tube and the bar-shaped camera can be accommodated within an area formed by the tongue piece and the barrier. ### Claim 16 (depends on 15) The tracheal intubation device as claimed in claim 15, wherein the bar-shaped camera is detachably connected to the handle portion.
