Definitions
- the present invention relates to an endobronchial tube having a length that enters a trachea, a distal end of which enters a left bronchus or a right bronchus, and has a lumen into which a fiberscope, a suction tube, or the like can be inserted.
- a double-lumen tube consists of a long lumen that enters the left or right main bronchus and a short lumen that stays in the trachea.
- the left or right main bronchial cuff and the tracheal cuff are two parts. By inflating the cuff, the airways of the left and right lungs are completely separated.
- both lumens are used simultaneously for the ventilation path.
- the lumen on the operating side is used as the deaeration path
- the lumen on the non-operative side is used as the ventilation path.
- One-lung ventilation using a bronchial blocker includes a method of using an endotracheal tube in which a bronchial blocker is pre-installed, and a method of introducing a bronchial blocker into an arbitrary endotracheal tube via a connector.
- a bronchial blocker is guided to the main bronchus on the operating side under observation with a fiberscope, and the ventilation is shut off by inflating the blocker balloon.
- double-lumen ventilation and single-lung ventilation can be performed only by hand, such as closing or releasing the left or right lumen.
- the space that can be used is narrow due to the structure that the tube lumen is divided into two parts, and only one fiber scope or thin suction tube can be used for single lung ventilation or both lung ventilation, making observation and suction difficult.
- the bronchial blocker system uses a single lumen to secure a wide lumen, but a mobile bronchial blocker may cause mispositioning, especially for the main bronchi.
- the right lung block which has a short length, has a problem that the position is apt to be abnormal. Disclosure of the invention
- the present invention has been made in view of the above points, and the problem is that after the tube is fixed, switching between bilungary ventilation and single-lung ventilation is possible only by operation at hand, and a thick fiber scope or a thick suction.
- the objective is to provide a single-run multi-bronchial endobronchial tube that can use a tube.
- Another object of the present invention is to achieve both the good operability with a double lumen tube and the securing of a wide lumen with a single lumen tube.
- the present invention provides a lumen which has a length to enter a trachea, a distal end of which enters a left bronchus or a right bronchus, and into which a fiberscope, a suction tube or the like can be introduced.
- a side opening communicating with the right or left bronchus is opened on the side of the tube body, and the tube body, the tracheal inner wall and A proximal outer cuff that seals the gap between the outside and the inside of the tube body, and an intermediate cuff to block ventilation at the point farther than the side port, is provided outside the tube body, which is closer to the side opening.
- Means is provided in which a distal outer cuff for sealing between the tube main body and the inner wall of the left or right bronchus is provided outside the tube main body at a position farther than the intermediate cuff.
- the present invention belongs to a single-lumen endobronchial tube.By using a single-lumen tube, it is possible to secure a large inner diameter, thereby enabling use of a fiberscope or a suction tube having a sufficient thickness. The internal observation and suction operation can be performed more effectively, and at the same time, after the tube is fixed, it is possible to switch between two-lung ventilation and single-lung ventilation with only the operation at hand. Therefore, the tube body has a wide inside diameter that allows use of a sufficiently thick fiberscope or suction tube. Bronchial fiber scopes are available in a variety of sizes, ranging from 2.0-2.5 mm to 6.0 mm for neonates and children. Similarly, there are various sizes ranging from 2.0 mm diameter to 6.0 mm diameter.

- the structure should be symmetrical to the above, with a curved shape so that the distal end enters the right bronchus.
- the lumen of the tube body is a one-chamber structure that penetrates from the proximal end to the distal end. By attaching a connector to the proximal end and connecting the breathing circuit, it becomes a ventilation passage.
- the aforementioned fiberscope and suction tube are inserted into the lumen.
- a side port is provided at a position on a side surface that leads to the right bronchus when the distal end enters the left bronchus, with the distal end entering the bronchi.
- the tube body for right bronchial introduction passes through the left bronchus when the distal end enters the right bronchus with the distal end entering the right bronchus.
- a side opening is provided at the position of the side surface to be twisted.
- the present invention uses a minimum of three cuffs to control the ventilation through the opening at the distal end of the tube body and the side opening, which is a side opening, to perform one-lung ventilation.

- a cuff that blocks air from flowing from the side port to the distal direction a cuff that seals the side port and tracheal inner wall by surrounding the entire circumference of the side port, and shuts off ventilation from the side port.
- the inner cuff is a cuff that closes the tube body lumen and blocks ventilation through the distal end of the tube body, and expands from the inner wall of the tube body lumen to close the tube lumen.
- a cuff that is supported by a ventilation tube at a location away from the inner wall of the lumen and closes the lumen of the tube body when inflated is an example of an intermediate inner cuff.
