Description

TECHNICAL FIELD OF THE INVENTION
The present invention relates to a cannula to be attached to an incised trachea, and more particularly to a cannula for preventing food from entering the trachea.
[0002]
[Prior art]
FIG. 4 is a perspective view of a conventionally used cannula. A tube 3 which is curved at about 90 degrees and is open at both ends is attached to an opening 2 of an arm 1. The trachea is incised for a person with insufficient respiratory function, a cannula is attached to the incision, and the trachea and the tube 3 communicating outside the body are breathed, thereby preventing the tracheostomy hole from closing naturally.
[0003]
In addition, as a cuffed cannula, a tracheostomy cannula that is used as a part of a circuit that sends oxygen into the patient's trachea by positive pressure from a ventilator and has a suction lumen on the cuff (see Patent Document 1), A tracheal connection tube (see Patent Document 2) which is used in a state inserted into the trachea from the mouth or into the trachea from the nostrils and in which a tampon-sack-shaped body which expands by the inflow of fluid is disposed through the glottis. Are known.

[Problems to be solved by the invention]
When wearing a cannula shown in FIG. 4 or a cannula with a cuff described in Patent Literature 1, when swallowing occurs, food that has entered the trachea can flow into the lungs as it is and develop swallowing pneumonia. High in nature. Further, the tracheal connection tube described in Patent Document 1 is mounted in the trachea through the oral cavity. In the state where the tube is present in the oral cavity, food cannot be chewed or swallowed in the oral cavity.
[0007]
Patients with reduced swallowing power and recurrent swallowing pneumonia often undergo tube feeding or infusion and fast. Surgery for otolaryngology (cricopharyngeal myotomy, occasional upper esophageal osteotomy, glottic closure, etc.) to prevent accidental swallowing is available, but is often used for elderly people with reduced physical strength Never. The number of patients who develop dysphagia, mainly due to cerebrovascular disorders and other diseases, increases as they age. At present in medical institutions, when a patient develops dysphagia and repeats swallowing, a tube inserted into the stomach from the nose (NG tube) or a tube inserted directly into the stomach from the body surface (stomach) (Fistula tube) to inject a liquid diet (tube feeding), and some patients administer nutrition by infusion. Then, oral dietary intake is stopped, and from that time on, the patient is deprived of the pleasure of eating and tasting.
[0008]
Therefore, the present invention provides a cannula capable of safely ingesting food orally for patients suffering from dysphagia and repeating swallowing.
[0009]
[Means for Solving the Problems]
The cannula with a tampon of the present invention includes a tampon that can be inserted and removed from a tracheostomy, in which a cannula having an arm portion on a tube inserted into the trachea from the tracheostomy is expanded by moisture to block the trachea just below the glottis. It is characterized by being.
[0010]
The tampon-equipped cannula of the present invention can be obtained by inserting a tampon into the patient's tracheostomy in front of the tracheostomy and inserting the tracheostomy cannula into the caudal side of the patient. The tampon inserted through the tracheal incision prevents erroneous swallows from flowing into the trachea due to swallowing disorders without adversely affecting mastication and swallowing, even in patients with reduced swallowing power. It does not develop pneumonia and allows oral dietary intake.
[0011]
BEST MODE FOR CARRYING OUT THE INVENTION
FIG. 1 is a perspective view showing an embodiment of the cannula of the present invention, and FIG. 2 is a view showing an example of a locking portion for locking a string of a tampon.
[0012]
In FIG. 1, a tube which is curved at about 90 degrees and is open at both ends is attached to the opening of the arm portion 1. A pair of slits 6 through which the strings 5 of the tampon 4 pass are formed in the arm portion 1, and the upper portion of the slits 6 is opened so that the strings 5 of the tampon 4 can be easily attached and detached. The string 5 should be connected at its end so that it does not fall into the trachea when worn. A through hole may be formed in place of the slit, but the slit 6 having an open top makes it easier to attach and detach the string 5 of the tampon 4 than the through hole.
[0013]
In FIG. 2, as a string fixing means for fixing the string 5 of the tampon 4 to the cannula, a string fixing stand 7 for locking the string 5 of the tampon 4 to the arm 2 is provided on the side of the arm 1 opposite to the tube 3. Provided. The string 5 is placed on the string fixing stand 7, and the string 5 and the string fixing stand 7 are fixed by the clipping tool 8.
[0014]
The clip 8 includes a base 9, and a resilient locking piece 11 that rotatably supports one end of the base 9 with the base 9 and inserts and locks the other end into the locking hole 10 of the base 9. The string 5 and the string fixing base 7 are fixed between the base 9 and the locking piece 11.
[0015]
The string fixing means is not limited to the one shown in FIG.
[0016]
The tampon 4 uses a known inflatable material that expands by absorbing moisture to close the head side of the trachea 12. For example, natural absorbent fibers such as cotton and flax used for sanitary tampon can be used.
[0017]
The method of using the cannula of the present invention will be described. FIG. 3 is a view showing a state in which the cannula of the present invention is mounted.
[0018]
(1) The two strings 5 of the tampon 4 are inserted from the upper portions of the two slits 6 of the cannula and passed therethrough.
[0019]
(2) Insert the tampon 4 cranially through the tracheostomy, and then insert the cannula tube 3 caudally through the tracheostomy.
[0020]
(3) At that time, since the string 5 is loosened between the tampon 4 and the cannula, the string 5 is pulled toward the cannula to reduce slack, and the two strings 5 are placed on the cannula string fixing stand 7. Then, the two strings 5 and the string fixing stand 7 are clamped together by the clip 8 to fix the strings.
[0021]
(4) Even if a patient who has developed dysphagia in this state ingests a meal orally, the tampon 4 prevents the meal from entering the trachea 12.
[0022]
(5) When removing the tampon 4, first remove the scissors 8, loosen the two strings 5 of the tampon 4 between the tampon 4 and the cannula, first remove the cannula from the tracheostomy fistula, and then Remove tampon 4.
[0023]
(6) Remove the string 5 of the tampon 4 from the cannula and discard the dirty tampon. The cannula is sterilized and used again.
[0024]
【The invention's effect】
ADVANTAGE OF THE INVENTION By this invention, it becomes possible for a patient who develops a dysphagia and repeats the accidental swallow to take a longer and safe oral dietary intake, and to continue the pleasure of eating and tasting.
