JP7017713B2 - Nostril cannula assist device - Google Patents

Description

The present invention relates to a cannula device for supplying a gas such as oxygen to a human body, and in particular, a cannula body having a tube member for supplying gas to supply the gas to the nostrils of the cannula wearer and the cannula body of the wearer. It relates to a nostril cannula assisting device having a positioning member for securely holding in the nostril.

A nostril cannula device used to supply a gas such as oxygen to a wearer who receives a gas such as oxygen from an oxygen supply device including an oxygen tank through the nostril of the wearer is disclosed in Patent Document 1 below. As is the case, its shape is generally known. However, when the wearer is lying sideways and his ears are in contact with the pillow, if the position shifts toward the back of the head and the earlobe bends toward the face, the cannula worn while hanging on the earlobe can easily be worn. It will come off. When the wearer is asleep or unconscious, oxygen and the like cannot be supplied from the nostrils in this state, which may be life-threatening. Despite these dangers, it is often difficult to say that the dangers have been fully explained at the time of wearing the nostril cannula. Further, as shown in Patent Documents 2, 3 and 4, measures for improving the above-mentioned drawbacks are also disclosed.

However, what is shown in Patent Document 2 is to fix the cannula body to the headband-shaped cannula holder through both sides of the wearer's nose, and the cannula tube itself blocks the wearer's line of sight. The fit is quite annoying. Patent Documents 3 and 4 connect a part of the cannula to a cap-shaped or flat plate-shaped joint portion arranged on the crown with a string-shaped member, and the structure and mounting are complicated in operation and must be properly mounted. There are drawbacks such as the effect of preventing the cannula from coming off does not work effectively. Further, since a material different from the material constituting the cannula itself is used, the productivity as a product is impaired and it becomes a factor of cost increase. Cost is not a life-changing issue for the wearer, but as a result it imposes a burden on the wearer.

Japanese Patent Application Laid-Open No. 2003-38647 Japanese Patent Publication No. 4188133 Utility Model Gazette No. 3144843 Japanese Unexamined Patent Publication No. 2006-61528

An object of the present invention is to provide a cannula assisting device capable of adding a reliable disengagement prevention function with a simple structure without impairing the convenience and wearing feeling of the currently used nostril cannula. As the material itself, the same kind of synthetic resin as the cannula can be used, and it provides a cannula assisting device for nostrils with excellent practicality without any trouble in manufacturing.

The present invention is a rational technique for solving the above-mentioned problems, and the first means thereof is to provide a flat plate-shaped connecting member in the vicinity of a portion where the cannula tube of the main body of the cannula assisting device for nostrils hangs on the left and right ears of the wearer. Attached, the connecting member is provided with a pair of first groove portions formed so that a groove portion having a wide entrance and a narrow groove portion in the middle is formed at two places on the left and right, and the groove portion is bent at a right angle and has a circular spreading portion at the back. , One end of a string-shaped member made of a flexible material is passed through the first groove portion from the left back surface to the front surface-front surface to the right back surface of the connecting member. The other end of the string-shaped member is attached to another connecting member in the same manner in the vicinity of the ear on the opposite side of the wearer, and the string member is in a state where the back of the head of the wearer is rotated. As a result, the cannula is firmly fixed at a predetermined position of the wearer as shown in FIGS. 1, 2 and 3, and can be prevented from being inadvertently removed due to rubbing of the pillow and the ear. It is easy to understand if it is regarded as the same as the attachment of swimming goggles, but it does not impose a burden on the wearer because it does not need to be tightened as strongly as swimming goggles.

The second means is to further form a second groove in the depth of the first groove formed on the left and right of the connection member, and to enable the attachment / detachment of the connection member to / from the cannula tube. The second groove has a common entrance with the first groove, the corner of the groove bent at a first right angle is branched, a second bent groove is provided in the back, and a circular spreading portion is provided in the back of the bent groove. It is a second groove portion having the above. The cannula tube has an extension that allows it to pass through the internal fluid passage within a range that does not extremely squeeze it. The connecting member is attached by passing a cannula tube through the second groove from the back surface on the left side of the connecting member to the front surface-from the front surface to the back surface on the right side. By doing so, the string member can be attached to the desired position without changing the cannula device itself from the conventional one. Therefore, the present invention provides a cannula assisting device for making a conventional cannula device without a holding function into a device with a highly safe holding function. The second groove portion in this structure is for maximally preventing an accident caused by the connecting member itself being detached from the cannula tube of the conventional cannula device.

A connecting member that hangs on the left and right ears of the tube member of the cannula device is attached, and a string-shaped member made of a flexible material is attached via the first groove portion of the connecting member, and the string-shaped member rotates around the back of the head. The cannula device, which is attached to the left and right connecting members, is displaced toward the back of the head while the wearer is lying sideways and his ears are in contact with the pillow, and even if the earlobe bends toward the face, the earlobe The cannula worn while hanging is not easily disengaged because the string-shaped member goes around the back of the head and is connected with the connecting member passing through the vicinity of the earlobe on the opposite side. If the wearer changes his / her posture and the earlobe separates from the pillow, the cannula will remain in its original state and will not cause any problems such as obstruction of suction of oxygen from the nostrils.

The second means of the present invention is that the connecting member is detachably attached to the cannula tube. Since the effect is not changed in the cannula itself, it is possible to add a function of preventing a disconnection accident simply by adding a connecting member and a string-shaped member to the conventional cannula device.
Further, since the cannula device itself does not need to change its shape, it is not necessary to manufacture a new mold or other manufacturing equipment. The string-shaped member made of flexible material only needs to be cut from the ready-made one, and the connecting member can be manufactured by press working or molding by small resin molding, which is low cost and puts a heavy burden on the wearer. It's not a thing.

Is a top view showing a wearing state of one embodiment of the nostril cannula device of the present invention.
In FIGS. 1, 2 and 3, the nostril cannula device 1 is provided with a suction unit 2 in which the wearer A sucks gas from the nostril portion B, and tube members 3 extending to the left and right from the suction portion 2 are left and right ears. The two tube members 3 hooked on C and under the chin of the wearer A are configured to be safely mounted in a state of being bundled by the ring 4.

Further, a connecting member 7 having a first groove portion 6 and a second groove portion 8 is arranged in the vicinity of a portion where the tube member 3 hangs on the left and right ears C. FIG. 4 is a partial plan view showing the shape of the connecting member 7. FIG. 5 is a QQ cross-sectional view in FIG. 4 showing an attached state of the connecting member 7 and the tube member 3. The connecting member 7 can be manufactured of a resin material on a flat plate. FIG. 6 is a PP cross-sectional view of the connecting member 7 showing a connection state between the string-shaped member 5 and the connecting member 7. As shown in FIG. 5, the connecting member 7 is attached to the tube member 3 in a state where the position can be arbitrarily adjusted by passing the tube member 3 through the second groove 8 from the left back surface to the front surface-from the front surface to the right back surface. Can be fixed. or. The shape and dimensions of the notch are determined so that the inner diameter of the tube member 3 is not deformed and the gas flow is not hindered. Further, the state of attachment of the connecting member 7 to the string-shaped member 5 is arbitrarily positioned by passing the string-shaped member 5 through the first notch 6 from the left back surface to the front surface-from the front surface to the right back surface as shown in FIG. Can be fixed in an adjustable state. As described above, the cannula device 1 in which the string-shaped member 5 is fixed to the tube member 3 in a state where the position can be adjusted in the vicinity of the portion hanging on the left and right ears C is rotated around the back of the head D of the wearer of the string-shaped member 5 to the left and right. Since it is fixed to the tube member 3 via the connecting member 7, the position of the head is displaced in the direction of the back of the head D while the wearer A is lying sideways and the ear C is in contact with the pillow. Even if the earlobe bends in the direction of the face, the tube member 3 does not easily come off because it goes around the back of the head and is connected to the vicinity of the earlobe on the opposite side via the connecting member 7.

If the wearer changes his / her posture and the earlobe separates from the pillow, the tube member 3 of the cannula remains in the original state of being worn on the wearer, and there is no problem such as the suction of oxygen or the like from the nostrils being hindered. Originally, this nostril cannula device is an important device that protects the life of the wearer, and if it is removed, the wearer is likely to suffer from respiratory failure and lead to a fatal accident, but its structure and wearing operation are simple. Therefore, it is not well known to the wearer and the nurse. In particular, for the purpose of preventing floor rubbing, a dangerous bed (mat device) that tilts to the left or right regardless of the wearer's consciousness may be used, but in this case, there is a particularly high risk that the cannula will come off. Moreover, bed makers and nursing service companies have not fully communicated the dangers to wearers and nurses. In such cases, the responsibility in the event of an accident remains ambiguous. Originally, either one should be held accountable. It is hoped that improvements will be made as soon as possible. What is described as a cannula device in the present specification may indicate a nostril cannula device.
