Description

  The present invention relates to a cannula holder that forms a tracheostomy opening in the front neck by tracheotomy and securely fixes the cannula inserted in the tracheostomy opening. The cannula can be fixed more securely than conventional products. It relates to a cannula holder.

For patients with upper airway obstruction or patients who use ventilators for a long time, a tracheostomy is formed in the patient's front neck and a special tube called a cannula is inserted into the tracheostomy. Has been done. The function of this cannula is important because it secures the airway and provides a place to connect a respiratory management device such as a ventilator, if necessary. Lead to medical accidents.
Usually, to prevent this, tie cotton tape (cotton string) to the two fixing holes on the left and right of the cannula, and then tie the cotton tape behind the patient's neck. Thus, the cannula is prevented from coming off. However, since cotton tape is a thin string, it can rub against the patient's neck and scratch it, which can be painful for the patient. Also, it is necessary to tie it at three locations (left and right of the cannula, behind the neck), and the knot is tied tightly so that it won't come off in an accident. It is complicated. Furthermore, it is not easy to adjust to an appropriate length without being too tight around the neck and not too loose.

Since cotton tape has such disadvantages, dedicated cannula holders have been commercially available from several companies in recent years. For example, since the cannula holder described in Patent Document 1 is a wide band-shaped product made of a soft material, it has good skin contact and does not cause pain to the patient. Moreover, since the fixation with the cannula and the adjustment of the length can be performed by attaching a tab made of a hook-and-loop fastener, the operation is very easy.
An example of a commercially available cannula holder is shown in FIG. The cannula holder is composed of a band part (3) that is turned around the neck and an elongated piece (hereinafter referred to as a cannula fixing tab) (1) made of a hook-and-loop fastener for fixing a cannula attached to both ends of the band part. The surface of the band part is made of non-woven fabric so that a surface fastener can be attached. The band part is divided into two bands (3a and 3b) so that the length can be adjusted according to the thickness of the neck, and a hook-and-loop fastener (hereinafter referred to as a length adjustment tab) is provided at one end of one band. Is attached to the surface of an appropriate position of the other band, and used integrally. In some cases, a rubber band (5) is inserted into a part of the band so that it can always be fitted to the movement of the neck.
The two cannula fixing tabs attached to both ends of the band are passed through the fixing holes (8) at both ends of the cannula (7), folded and attached to the surface of the band. The band itself is wrapped around the patient's neck. This secures the cannula so that it does not fall out of the tracheostomy.
In this way, compared to cotton tape, the cannula holder is a soft band with a wide band shape, so it is comfortable because it does not hurt the patient's skin, and the cannula is fixed with a hook-and-loop fastener and the length of the band Since it can be adjusted, its operation is very easy.
On the other hand, if the hook-and-loop fastener is not applied properly, the hook-and-loop fastener may come off, or if used on a child or a patient with consciousness, the patient may unintentionally remove the hook-and-loop fastener. In such a case, it will lead to an accident where the curl is lost. Since cotton tape is usually tied tightly, such an accident does not occur.
A highly safe cannula holder that has the advantages of being comfortable and easy to operate but preventing the cannula from coming off has been desired.

International Publication Number WO2005 / 084740

  An object of the present invention is to provide a highly safe cannula holder that does not damage a patient's skin, can be easily attached and cannulated, and can prevent the cannula from coming off.

  In addition to the two cannula fixing tabs attached to both ends of the band, the present invention has a tab made of another hook-and-loop fastener that holds the tab from above so that the tab does not easily peel off from the surface of the band. It is characterized by that. That is, after the cannula fixing tab that has passed through the fixing hole of the cannula is folded and attached to the surface of the band part, another tab wider than the tab for fixing the cannula is attached to the tab, and the tab is fixed twice. This prevents the cannula from coming off due to an accident.

The cannula holder according to the present invention includes a tab inserted into a fixing hole at both ends of the cannula and folded to fix the cannula to the patient's neck, and the folded portion of the tab is composed of another wide surface fastener from above. It can be securely fixed by holding it with a tab and fixing it twice.

  The cannula holder according to the present invention will be described in detail with reference to examples.

FIG. 2 is a perspective view of a cannula holder according to the present invention. The band part that wraps around the patient's neck, the cannula fixing tabs attached to both ends of the band, and a wide surface fastener that holds down from the top to prevent it from peeling off easily when the tab is attached to the band surface Tabs (hereinafter referred to as pressing tabs).
Since the cannula fixing tab needs to pass through the fixing hole of the cannula, the width needs to be thin and about 5 to 6 mm.
The holding tab has a width of about 15 to 20 mm in order to fulfill its function, and is fixed to the band portion at a location several cm away from the end of the band portion.
The width of the band portion wound around the patient's neck is about 25 mm, and the material is not particularly limited, but there is a material that is soft and strong enough to hold the cannula so as not to cause scratching on the patient's neck. desired. The surface is preferably such that a hook-and-loop fastener can be easily attached, and specifically, a nonwoven fabric or the like is preferable. In addition, the band part may have a layer structure using different materials. For example, the back side in contact with the skin is a cotton cloth, the center part is urethane foam, and the front side to which the tab is attached is a three-layer structure such as a non-woven fabric. It may be. The band part can be divided into two, and it is possible to adjust the length in a wide range if it can be fixed at any place on the other band surface with a hook-and-loop fastener for adjusting the length fixed to one band It is preferable because it is possible. A rubber band in the middle of the band portion is preferable because it always fits against the movement of the neck.

When the cannula holder according to the present invention is used, the cannula fixing tab is passed through the fixing hole of the curule, and then folded and attached to the surface of the band. Thereafter, a pressing tab is attached to the surface of the band so as to cover the cannula fixing tab. This can greatly reduce the risk of the cannula securing tabs coming off the surface of the band. Removing the cannula requires a two-step operation of removing the holding tab and then removing the cannula fixing tab, greatly reducing the possibility of accidental removal by children and conscious patients. To do.
When fixing or removing, there is a two-step operation, so the operability is slightly inferior to that of the conventional cannula holder, but the operability is still much better than using cotton tape.

  The fixing portion to the band portion of the pressing tab of Example 1 is the upper end of the tab.

  Since it was possible to provide a highly safe cannula holder that is comfortable for the patient and that can prevent the cannula from being removed while maintaining the ease of attachment and removal for the operator, the industrial applicability thereof is great.
