Description

Nasal tube device

The present invention relates to a medical device for clearing the respiratory tract, and more particularly to a nasal cannula device.

Referring to Figure 1, a prior art nasal cannula device 9 includes a nasal seat 91 and a hose member 92 that is hollow and combined with the nasal seat 91. The nasal seat 91 includes a portion 911, a nasal connecting portion 912 connected to the seat portion 911 for insertion into the nasal cavity, and a surrounding portion 913 connected to a side of the seat portion 911 opposite to the nasal connecting portion 912. . The surrounding portion 913 and the seat portion 911 collectively define a through space 914. The hose member 92 includes a combination end 921 that abuts against the seat portion 911. The combined end 921 has a vent 922 that faces the seat 911. When the nasal seat 91 and the hose member 92 are combined, the combined end 921 is inserted into the wearing space 914 to keep the combined end 921 against the seat portion 911. In this way, when the positive pressure is introduced into the hose member 92, the positive pressure can be introduced into the nasal joint portion 912 through the vent 922, thereby maintaining a positive pressure in the nasal cavity to achieve the effect of clearing the respiratory tract. . However, due to the positive pressure, the seat portion 911 is easily pressed by the positive pressure, so that the combined end 921 cannot firmly abut against the seat portion 911. Further, since the seat portion 911 is warped, the position of the nose connecting portion 912 is also displaced, which causes an uncomfortable feeling.

Therefore, the purpose of the present invention is to provide a nasal tube device that is relatively stable and enhances comfort.

Thus, the novel nasal tube device comprises a nose piece. A first axial direction and a second axial direction transverse to the first axial direction are defined. The nose piece includes a base portion, two nasal joint portions connected to the base portion, two wear fixing portions connected to the base portion, and two hose fixing portions connected to the base portion.

The base has two sides spaced along the first axis, a first edge connected between the sides, a connection between the sides and along the second axis and the first a second edge spaced apart by the edge, an outer surface surrounded by the first edge, the second edge and the sides, and an inner surface opposite the outer surface. The nose joint portions are hollow tubular and project in a direction away from the outer surface and are spaced apart along the first axial direction. Each nasal joint portion and the base define a venting passage extending along the nasal joint portion and extending therethrough to the inner surface. The wear fixing portions are respectively connected to both sides of the base along the first axial direction and extend away from the base.

The hose retaining portions extend toward a side opposite the nose cap portions and are generally Y-shaped. The hose fixing portions are respectively connected to the first edge and the second edge. Each hose fixing portion has two branching sections connected to the base, and a trunk section connected to the equalizing sections. The sub-segment segments are respectively adjacent to the sides and extend away from the base and meet each other. The sub-segment and the base jointly define a hollow area. The trunk section is connected to the intersection of the branches.

The utility model has the advantages that the hose fixing portion is substantially Y-shaped, so that the base portion is less likely to warp, thereby improving stability and comfort.

Referring to Figures 2 and 3, an embodiment of the novel nasal tube device includes an nose piece 1, a hose member 2, and a band 3.

Referring to Figures 4, 5 and 6, a first axial direction D1 and a second axial direction D2 transverse to the first axial direction D1 are defined. The nose piece 1 includes a base portion 11 , an extension portion 12 (refer to FIG. 7 ) connected to the base portion 11 , a nose joint portion 13 connected to the base portion 11 , and two connected to the extension portion 12 and indirectly connected thereto. The wear fixing portion 14 of the base portion 11 and the hose fixing portion 15 connected to the base portion 11 are provided.

The base portion 11 has two side edges 111 spaced along the first axial direction D1, a first edge 112 connected between the side edges 111, a connection between the side edges 111 and along the second a second edge 113 spaced apart from the first edge 112 by an axial direction D2, an outer surface 114 surrounded by the first edge 112, the second edge 113 and the sides 111, and a surface opposite to the outer surface Inner surface 115 of 114. The nose joint portions 13 are hollow tubular and project in a direction away from the outer surface 114 and are spaced apart along the first axial direction D1. The nose joint portions 13 are also bent toward the second edge 113 when protruding in a direction away from the outer surface 114. Each nasal joint portion 13 and the base portion 11 define a venting passage 16 extending along the nasal joint portion 13 and extending therethrough to the inner surface 115.

The extension 12 extends from the second edge 113 toward a side opposite the nose joint portion 13. The wear fixing portions 14 are respectively connected to both sides of the extending portion 12 along the first axial direction D1 and extend away from the base portion 11. Each of the wearing and fixing portions 14 has a fixing hole 141 for connecting the band 3, and a pad 142 adjacent to the fixing hole 141.

The hose fixing portions 15 extend toward the side opposite to the nose tube portions 13 and are generally Y-shaped. The hose fixing portions 15 are respectively connected to the first edge 112 and the second edge 113. For convenience of explanation, the hose portion connected to the first edge 112 is indicated at 150 below, and the hose fixing portion connected to the second edge 113 is indicated at 151. The hose fixing portion 150 has the same structure as the hose fixing portion 151 except that the length ratios are different. The hose fixing portion 151 is connected to the extending portion 12 and indirectly connected to the base portion 11. The hose fixing portion 150 and the hose fixing portion 151 each have a branching section 152 connected to the base portion 11 or the extending portion 12, a trunk section 153 connected to the branching sections 152, and a The button hole 154 of the trunk section 153. The sub-segment segments 152 are respectively adjacent to the side edges 111 and extend away from the base portion 11 and meet each other. A plurality of hollowed out regions 17 are defined around the subsections 152 and the base portion 11. The trunk section 153 is connected to the intersection of the equal sections 152.

Referring to Figures 2, 3 and 8, the hose member 2 is hollow tubular around a centerline R and has a mounting end 21 disposed along the centerline R and adapted for mounting on a ventilator, and an edge The center line R is disposed at the combination end 22 on the side opposite to the mounting end 21 (the ventilator is not the focus of the present case, so the figure is not shown). The assembly end 22 has an end body portion 221 defining a venting opening 223 and a latching portion 222 projecting from the end body portion 221. The vent 223 faces a direction perpendicular to the center line R. The buckle portion 222 is located on the opposite side of the vent 223 and has a buckle portion 224 connected to the end body portion 221 and a buckle cap portion 225 connected to the buckle body portion 224.

The cuff 3 is connected in an elongated manner between the wear fixing portions 14 of the nose piece 1. The cuff 3 includes a strip 31 in the form of a strip, and two latching members 32 respectively disposed at opposite ends of the strip 31. The latching members 32 are respectively fastened to the fixing holes 141 of the wearing and fixing portions 14 . The pads 142 of the wear fixing portion 14 protrude toward one side of the second edge 113 and cover the respective snap members 32 and the fastening holes of the fixing holes 141.

Referring to FIG. 2, FIG. 5 and FIG. 6, when the nose piece 1 is combined with the hose piece 2, the combined end 22 abuts against the base 11 by one side of the inner surface 115, and the vent 223 communicates with the Wait for the airway 16. The trunk segments 153 of the hose fixing portions 150 and 151 are sleeved on the buckle body portion 224 (see FIG. 8 ) through the fastening holes 154 and are engaged by the buckle cap segments 225 , and are thus connected to the combination end 22 . The hose fixing portions 150, 151 and the base portion 11 are further caused to surround the combined end 22 to hold the combined end 22 against the base portion 11.

In use, the nose piece 1 and the hose piece 2 must be combined with each other and the mounting end 21 is mounted to the ventilator. The user wears the embodiment to the head by the cuff 3, and the nose portions 13 are inserted into the two nostrils of the user, respectively. After the wear is completed, the gas can be introduced into the hose member 2 by the ventilator. The gas passes through the nose piece 1 and reaches the user's nasal cavity, thereby creating a positive pressure in the user's respiratory tract to assist in breathing.

Referring to FIG. 5 and FIG. 6 , in the present embodiment, the hollowed out regions 17 are defined by the equal dividing segments 151 and the base portion 11 , and the functions thereof are: the main trunk segments 153 are constrained to the hose member 2 . The force is diverted to the subsections 152. Since the side of the branching section 152 adjacent to the base 11 is adjacent to the sides 111, respectively, when the nose joints 13 are subjected to positive pressure, the sides 111 are subjected to the equal sections. The pulling of 152 does not easily cause the base 11 to warp. In addition to this, in the present embodiment, the base portion 11 and the extension portion 12 together form an L-shaped structure which enhances the performance of the base portion 11 against bending moments, thereby also making the base portion 11 less prone to warpage. Since the base portion 11 is less likely to warp, the hose member 2 is relatively stable when it abuts against the base portion 11. In addition, the positions of the nose joint portions 13 are not affected by the warpage, and the comfort is improved.

Referring to Fig. 6 and Fig. 7, in addition, in use, it is usually necessary to wear the embodiment for a long time. When worn, the pads 142 will adhere to the cheeks without causing the fasteners 32 to directly reach the cheeks, so that they can remain comfortable during long-term wear.

In summary, the novel nasal tube device is substantially Y-shaped by the hose fixing portions 150, 151 and is defined together with the base portion 11 to define the hollow portion 17, so that the branching portions 152 can be applied intensively. The force direction toward the side edges 111 makes the base portion 11 less likely to warp, thereby improving the stability and comfort, so that the purpose of the present invention can be achieved.

However, the above is only the embodiment of the present invention, and when it is not possible to limit the scope of the present invention, all the simple equivalent changes and modifications according to the scope of the patent application and the contents of the patent specification are still This new patent covers the scope.
