Abstract

<P>PROBLEM TO BE SOLVED: To provide an endotracheal intubation tube with lumens for sucking the top of a cuff, which sucks a stored matter stored at the top of the cuff for the endotracheal tube due to misswallowing in the case of endotracheal intubation carried out in the case of resuscitation or in the case of emergency surgery. <P>SOLUTION: The endotracheal intubation tube with the lumens for sucking the top of the cuff has the suction lumens 3 and suction opening parts at the top of the cuff, and has the suction lumens 5a, 5b, a lumen 3 for maintenance of the airway and a small lumen 4 for swelling the cuff formed, respectively, along the direction of a long shaft in the thick part of a tubular body. The lumen 3 for maintenance of the airway constitutes the tubular body. The suction lumens 5a, 5b and the small lumen 4 for swelling the cuff are formed integrally with the thick part of the tubular body. The suction opening parts 6a and 6b are formed at two places of the right and left of the top of the cuff by cutting. <P>COPYRIGHT: (C)2006,JPO&NCIPI

Description

  The present invention relates to an endotracheal intubation tube that is inserted into a trachea in order to secure a patient's airway and perform artificial respiration during emergency resuscitation or general anesthesia.

In the field of clinical medicine, when resuscitating a serious and unconscious patient or during general anesthesia for surgery, it is necessary to secure an airway and perform artificial respiration, and in that case, endotracheal intubation is performed.
JP 2001-516252 A

  Japanese Unexamined Patent Publication No. 2001-516252 is a prior art document disclosing the prior art regarding the shape of an endotracheal intubation tube used for respiratory management by endotracheal intubation. The prior art based on this prior art is handed over to each literature, but here, what has a configuration close to that of the present invention will be described with reference to a conventional example as shown in FIG.

  As shown in FIG. 2 (a), the shape of a conventional endotracheal intubation tube is such that a cuff 2 is provided at the distal end of the main body 1 of the endotracheal intubation tube. As shown in b), the whole part is appropriately expanded or contracted by pressurizing or depressurizing the hollow part through the cuff expansion small lumen 3 provided in the thick part of the tube body 1. Is possible.

  According to the instrument of FIG. 2 (a), before the non-emergency standby operation, the endotracheal intubation that is performed after preparing to reduce the stomach contents such as fasting and drinking, as shown in FIG. The risk of aspiration in which stomach contents flow into the trachea 11 from the esophagus 12 due to vomiting is low, and this operation is usually performed safely.

  However, according to the above techniques, during emergency resuscitation or endotracheal intubation during emergency surgery for patients with intestinal obstruction or patients who have to undergo surgery immediately after eating food, Alternatively, after intubation, stomach contents may flow backward from the esophagus 12 into the trachea 11 and be stored in the upper part of the cuff 2 of the endotracheal intubation tube 1.

  However, since the cuff 2 of the endotracheal intubation tube is placed in the trachea 11 beyond the vocal cord 10 as shown in FIG. 3, a suction fistula used for medical purposes is inserted up to the same site. Thus, it is difficult to suck and remove the accumulated material in the upper part of the cuff 2 of the endotracheal intubation tube. In other words, when the intubation tube 1 is extubated, it cannot be aspirated and removed so that this reservoir does not flow from the trachea into the lung periphery.

  Therefore, if the cuff 2 is contracted as it is and the intubation tube 1 is extubated, the reservoir in the upper part of the cuff 2 flows from the trachea into the periphery of the lung, presenting a pathological condition of aspiration pneumonia, and sometimes fatal. There is.

  In order to solve the above-mentioned problem, the present invention provides a suction cuff upper suction in which a suction lumen and a suction opening are integrally formed in a thick part of an endotracheal intubation tube at two upper cuff locations. A lumen endotracheal intubation tube is provided.

Therefore, in the first invention, the suction lumen capable of sucking the reservoir and the suction opening are integrally formed in the thick portion of the endotracheal intubation tube at the upper part of the cuff of the endotracheal intubation tube. This is an endotracheal intubation tube.
The second invention is an endotracheal intubation tube characterized in that suction capability is improved by providing suction lumens at two positions on the left and right of the upper part of the cuff.

  According to the first invention or the second invention, the suction lumen capable of sucking the reservoir and the suction opening are provided in the upper part of the cuff of the endotracheal intubation tube. This reservoir can be aspirated before the tube is extubated, and the inflow of the reservoir from the trachea to the periphery of the lung and the pathological condition of aspiration pneumonia caused by it can be avoided.

Embodiments of the present invention will be described with reference to the drawings.
FIG. 1 is a schematic configuration explanatory view of an endotracheal intubation tube with a cuff upper suction lumen according to the present invention, FIG. 1 (a) is a perspective external view, and FIG. 1 (b) is an AA cross-sectional view. In FIG. 1A, a tube 1, a cuff 2, an airway securing lumen 3 and a cuff inflation small lumen 4 excluding suction lumens 5a and 5b will be described with reference to FIG. Since the parts have the same structure and function as the parts made, the description thereof will be omitted.

  The tube 1 in the present embodiment is a slightly curved lumen body as in FIG. An airway securing lumen 3, a cuff inflation small lumen 4, and suction lumens 5 a and 5 b are integrally formed in the thick portion of the tube 1.

  Suction openings 6a and 6b are formed at predetermined locations on the upper part of the cuff 2 so that the ends of the suction lumens 5a and 5b are exposed to the outside of the tube. Further, the suction openings 6a and 6b are connected to the suction pipe connecting parts 7a and 7b via the suction lumens 5a and 5b. By connecting the suction pipes to the same parts, the reservoir in the upper part of the cuff 2 is sucked. can do.

"Effect of the embodiment"
According to this embodiment, the upper portion of the cuff 2 can be sucked by the action of the suction openings 6a and 6b, the suction lumens 5a and 5b, and the suction pipe connecting portions 7a and 7b. Therefore, the reservoir in the upper part of the cuff 2 that flows in when the airway is secured is removed, and fatal symptoms such as aspiration pneumonia can be avoided.

It is a perspective view which shows one Embodiment of this invention. FIG. 1A is a perspective external view, and FIG. It is a perspective view which shows a prior art. 2A is a perspective external view, and FIG. 2B is an AA cross-sectional view. 1 is a side view of a pharyngeal larynx with a prior art cuffed endotracheal intubation tube placed in the airway.
