Abstract

(57) [Summary] [Purpose] An object of the present invention is to provide a cannula for trachea which does not cause irritation or damage to tracheal mucosa by a pipe inserted into the trachea even when the neck is moved. [Structure] One end has a pipe inserted into the trachea, and the other end has a tracheal cannula constituted by an elastic silicone consisting of a tubular connector to which a valve for introducing air can be attached. -A cord-shaped connecting piece is provided on the side surface of the connector, and the trachea cannula is attached to the tip of the connecting piece.
The tracheal cannula is characterized in that a fixing hole for holding the tray is provided.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a tracheostomy cannula to be attached to the trachea of a tracheotomized patient.

[0002]

[Prior art]

 Conventionally, tracheostomy is applied to patients who have dyspnea due to airway stricture above or above the trachea or glottis, and a cannula is attached to the site opened by the operation to endotracheally. It is done to let the air flow into. This cannula is made of fluororesin or silicone resin having a wall thickness of about 0.5 to 1.0 mm, and its structure is, for example, as shown in FIG. An end portion 7 of the air introduction pipe 1 for introducing air into the trachea is fixed to the central portion, and fixing holes 4 are provided at both ends of the frame 6. To attach this cannula to the trachea, open the trachea created by the surgery, insert the air introduction pipe 1 into the trachea, and pass it through the fixing hole 4 around the neck and turn it around the neck. It is fixed.

However, in such a conventional cannula, since the frame 6 and the air introduction pipe 1 are integrally joined, the rotation and bending movement of the neck are restricted, Further, there is a drawback that the tip portion of the air introduction pipe 1 moves due to the movement of the neck, which causes irritation or damage to the tracheal mucosa. In order to improve this drawback, as shown in FIG. 3, the frame 6 and the air introducing pipe 1 are not integrated, but a spherical connecting piece 8 is interposed between the air introducing pipe 1 and the frame 6. In order to prevent the movement of the neck from being directly transmitted to the tip of the introduction pipe, the tip of the air introduction pipe 1 should not be used to cause irritation or damage to the tracheal mucosa. However, it cannot be said to be completely satisfactory.

DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention The present inventor has completed the present invention as a result of various studies on a tracheal cannula in which the distal end portion of the introduction tube does not stimulate or damage the tracheal mucosa. The purpose of the above is to provide a tracheostomy cannula that does not cause irritation or damage to the tracheal mucosa by the pipe inserted into the trachea even when the neck is moved.

[0005]

[Means for Solving the Problems]

 The gist of the present invention is that one end has a pipe inserted into the trachea and the other end is constituted by an elastic silicone consisting of a tubular connector to which a valve for introducing air can be attached. A tracheal cannula, characterized in that a string-like connecting piece is provided on the side surface of the connector, and a fixing hole for holding the tracheal cannula is provided at the tip of the connecting piece. It is Les.

That is, in the present invention, an air introduction pipe is provided in the tubular connector instead of the conventional flange-shaped frame, and the tip of the string-shaped connecting piece projecting from the side wall of the connector. Since a fixing piece is provided on the part, the cannula is flexible not only when the neck is moved forward, backward, leftward and rightward, but also when the neck is moved forward and backward, right and left, the string of elastic silicone. Since it is fixed via the connecting piece of the air introduction pipe, even if the tip end of the air introduction pipe touches the tracheal wall, it does not apply excessive pressure to the tracheal mucosa, irritate or damage it. .

The drawings of the present invention will be described. FIG. 1 is a perspective view of a cannula of the present invention. In FIG. 1, an air introduction pipe 1 to be inserted into the trachea is attached to one end of a connector-2, and an air introduction valve is fitted to the other end 5 of the connector. Then, a string-shaped connecting piece 3 is projected from the side surface of the connector, and a fixing hole 4 is provided at the tip thereof.

When using this cannula, a pipe is introduced into the trachea through a tracheotomized hole, and a string or the like is attached to the fixing hole and fixed around the neck. It is also possible to have a conversation by attaching a speech valve as an air introduction valve of the connector.

[0009]

[Effect of device]

 As described above, in the present invention, since the cannula is fixed by the elastic silicone, even if the tip of the pipe directly touches the tracheal wall by the movement of the neck, the tracheal mucosa is excessively touched. It exerts less pressure and is less likely to cause irritation or damage. Therefore, it has the effect of allowing easy movement such as rotation and flexion of the neck and long-term continuous use.
