Description

The present invention relates to a tracheostomy tube holder.

In recent years, the number of children receiving medical care has been increasing. According to the materials of the Ministry of Health, Labor and Welfare, children with medical care are those who continue to use artificial respirators, gastrostomy, etc., and suck sputum after long-term hospitalization in the NICU (neonatal intensive care unit), etc., against the background of medical progress. This refers to children with disabilities who require daily medical care such as feeding and tube feeding.

Among children requiring medical care, for example, there are patients whose trachea is partly collapsed due to a disease called tracheomalacia, and therefore the trachea must be incised to form a tracheostomy. A cannula is attached to the tracheostomy opening to secure respiration, and a speech valve or an artificial nose is attached to perform vocalization and respiration (see, for example, Patent Document 1 below). As used herein, the term "cannula" refers to a pipe-shaped medical instrument that is inserted into a body cavity, blood vessel, or the like and used as an air passage during tracheotomy.

By the way, instead of a cannula for the tracheostomy, a substantially T-shaped tube made of a flexible material is used. Non-Patent Document 1 below, for example, describes a technique relating to a tracheostomy tube that prevents obstruction of the trachea by protruding from the trachea and enables securing of the airway through the tracheostomy hole.

The technology related to the tracheotomy tube described in Non-Patent Document 1, unlike a cannula, can be made very small and is made of a flexible material such as silicone, which makes it easier for patients (users) to use. It is useful because it has the advantage of less burden.

However, since the tracheostomy tube is made of a flexible and small material, it may come out of the trachea by pulling the portion protruding from the tracheostomy of the user. In this case, first aid must be given before moving to a medical institution where the operation can be performed, and surgery to insert a tracheotomy tube must be performed again. In other words, if the tracheostomy tube were to come off, there would be a problem that a heavy burden would be imposed on the user.

Therefore, in view of the above problems, an object of the present invention is to provide a tracheostomy tube holder that makes it difficult for the tracheostomy tube to slip out of the tracheostomy hole.

A tracheostomy tube holder according to one aspect of the present invention for solving the above problems is a tubular tube holder having a notch and capable of holding a tracheostomy tube inside, and a tube holder connected to the tube holder. and a throat part formed in a substantially V-shape to be applied to the user's throat, having a hole for passing the band through at the end thereof.

Moreover, in this aspect, although not limited, it is preferable that the tube holding portion and the throat portion are integrally formed of elastomer.

Moreover, in this aspect, although not limited, the opening angle of the pair of throat guards is preferably greater than 90 degrees and less than 180 degrees.

Moreover, in this aspect, although not limited, it is preferable that the throat guard portion and the tube holding portion are connected via a connection base portion.

Moreover, in this aspect, although not limited, it is preferable that the throat guard portion and the connection base portion have a notch portion corresponding to the notch portion of the tube holding portion.

As described above, the present invention can provide a tracheostomy tube holder that makes it difficult for the tracheostomy tube to slip out of the tracheostomy hole.

More specifically, FIG. 1 is a perspective view of the book holder 1, FIG. 2 is a top view of the book holder 1, FIG. 3 is a bottom view of the book holder 1, FIG. , and FIG. 6 is a right side view of the book holder 1. As shown in FIG. Note that the left side view is omitted because it is represented in the same manner as the right side view.

7 is a schematic diagram of the tracheostomy tube T, FIG. 8 is an image diagram when the tracheostomy tube T is attached to a patient (user), and FIG. It is an image when it is attached to the user.

As shown in these figures, the holder 1 is connected to a tubular tube holding portion 2 having a notch 21 and capable of holding a tracheostomy tube inside, and the tube holding portion 2, A hole 31 for passing a band is formed at an end portion, and a throat support portion 3 is formed in a substantially V shape to be applied to the user's throat.

This holder 1, with the above-described configuration, makes it difficult for the tracheostomy tube T to slip out of the user's throat and can stably hold it in the user's throat.

Further, the material of the main holder 1 is not limited as long as the main holder 1 can exhibit its effect, and it is preferable that the main holder 1 is integrally formed of an elastomer. An elastomer is a polymer compound having elasticity, and may be, for example, a thermosetting elastomer such as urethane rubber or silicone rubber, or a thermoplastic elastomer such as polyvinyl chloride or polyurethane. Further, it is preferable that the tube holding portion 2 and the throat guard portion 3 are integrally formed from the viewpoint of strength and manufacturing efficiency, but they may be manufactured separately, joined together, and integrally formed.

Further, in the present holder 1, the tube holding portion 2 is a cylindrical member provided with the notch 21 as described above and capable of holding the tracheostomy tube T inside. A notch 21 is provided so that this part can be opened slightly and the tracheostomy tube T can be inserted and removed. A knob portion 22 is formed around the notch 21 in the tube holding portion 2, and the size of the notch 21 can be adjusted.

Moreover, in the main holder 1 , it is preferable that the tube holding portion 2 is connected to the throat rest portion 3 via the connection base portion 4 . The material of the connection base portion 4 is also the same as that of the tube holding portion 2 . It may be integrally formed with the tube holding portion 2 and the throat guard portion 3, or may be integrally formed by manufacturing them separately and joining them.

In the present holder 1, the tube holding portion 2 is a portion that undergoes large movements such as opening and closing the notch to hold the tube as described above. On the other hand, since the throat guard 3 has a shape that is stable to some extent and contacts the user's throat as will be described later, there is a difference in the degree of deformation between them. Therefore, the connection base part 4 is provided in order to solve these problems.

Moreover, it is preferable that the throat part 3 and the connection base part 4 have cutouts corresponding to the cutouts of the tube holding part 2 . Specifically, the connecting base portion 4 is not provided in the cutout portion 21 of the tube holding portion 2, that is, the cutout portion 41 is provided. As a result, a fixing member is not provided around the notch 21, which has a large movement, in the tube holding part 2, while stable connection is possible by the connection base part 4 at a place apart from the notch 21. - 特許庁

Further, the throat part 3 in the main holder 1 is connected to the tube holding part 2 via the connecting base part 4 as described above, and is intended to be applied to the user's throat.

Further, in the holder 1, a hole 31 for passing the band B is formed at its end. The user can fix the holder 1 to the throat by passing the band B through the hole 31, winding the band B around the neck, and passing it through the other hole 31 as well.

Further, in the present holder 1, it is preferable that the throat part 3 is formed in a substantially V-shape so as to be applied to the user's throat. With such a shape, there is an advantage that the band B can be hung, and the band B can be wrapped around the neck relatively loosely without the need to tighten the band so tightly that it becomes painful. In this case, the opening angle of the pair of throat guards 3 is preferably greater than 90 degrees and less than 180 degrees, more preferably 110 degrees or more and 130 degrees or less.

As is clear from the above figures, the present holder 1 preferably has a configuration in which the notch 21 of the tube holding portion 2 is provided on the acute-angled side of the V-shape. By doing so, the acute-angled side of the V-shape becomes the side closer to the user's chin (upward in the vertical direction), and along with this, the notch 21 of the tube holder 2 also becomes the side closer to the chin (upward in the vertical direction). The insertion and removal of the tube holder 2 of T can be performed from above in the vertical direction, and the possibility that the tracheostomy tube T will fall off due to gravity can be reduced.

As described above, the present holder 1 serves as a tracheostomy tube holder that makes it difficult for the tracheostomy tube T to slip out of the tracheostomy opening. Further, as an additional effect of the present holder 1, for example, it is possible to reduce the risk of narrowing of the airway due to the tracheostomy tube T sagging due to its own weight, and the possibility of the tracheostomy tube entering the trachea. can also be prevented. Furthermore, the movement of the tracheostomy tube T has the effect of suppressing the occurrence of granulation in the throat of the user.
