Detailed Description
Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. The following embodiment is an embodiment of the present invention, and the present invention is not limited to this embodiment.
Fig. 1 is a perspective view showing an oxygen mask according to an embodiment of the present invention, and is a view showing a state in which a connector (oxygen introducing portion) for connecting an oxygen supply tube is detached from a mask body portion.
As shown in fig. 1, the oxygen mask 1 of the present embodiment has a basic configuration including a mask body 11 covering a nose and a mouth, and an oxygen supply tube connecting connector (oxygen introducing portion) 12 detachable from the mask body 11.
Fig. 2A to 2C are views showing the mask body, in which fig. 2A is a plan view, fig. 2B is a front view, and fig. 2C is a side view. Fig. 3 is a perspective view from the bottom surface side.
The mask body 11 has an inhalation unit 111 covering the nose and an exhalation unit 112 covering the mouth. That is, as shown in fig. 2C and the like, by providing the partition portion 114 at a position of the lower surface of the portion that covers the nose, the air intake portion 111 has a shape that covers only the substantial nose portion, and is formed to cover the bulge portion of the nose as a whole.
A connector mounting hole 113 for mounting the oxygen supply tube connecting connector 12 is formed in a partition portion 114 which is a lower surface of the inhalation portion 111 (a connector mounting hole is formed so as to open downward in the mask body portion). The oxygen supply tube connecting connector 12 is attached to the connector attachment hole 113, and an oxygen supply tube (not shown) connected to an oxygen supply source is connected to the oxygen supply tube connecting connector 12, whereby oxygen is supplied into the inhalation unit 111 of the mask body 11.
The mask body 11 is configured to spatially divide the inhalation unit 111 and the exhalation unit 112, thereby reducing a decrease in oxygen concentration due to exhalation.
As shown in fig. 3, an external gas communication hole 1112 is formed in the partition 114 which is the lower surface of the intake unit 111. The external gas communication hole 1112 is a hole for discharging exhaled air from the nose to the outside, and introducing and mixing external gas when the amount of sucked oxygen is larger than that of supplied oxygen when oxygen is sucked.
The oxygen mask 1 is attached to the face by attaching a rubber string or the like to an insertion hole H formed in the peripheral portion of the mask body 11 and then hanging the rubber string or the like over the ears or around the head (this is the same as in the conventional oxygen mask).
The exhalation module 112 functions as a "moisture retention mask" and uses moisture of the exhaled air to prevent drying of the lips (the exhaled air containing moisture is retained to some extent around the lips).
The oxygen mask 1 of the present embodiment has laterally long exhaust holes 1121 formed in the front surface of the exhalation module 112, and circular exhaust holes 1122 formed in the side surface of the exhalation module 112.
In the present embodiment, the structure in which the air vent hole is formed in both the front surface and the side surface of the exhalation module 112 is taken as an example, but the present invention is not limited to this, and a through hole may be formed only in the front surface of the exhalation module and an air vent hole may be formed only in the side surface. In addition, in the case where the exhalation module has an upper surface portion as in the present embodiment, an exhaust hole may be formed in the upper surface portion.
In the present embodiment, the structure in which the laterally long exhaust holes 1121 are formed in the front surface and the circular exhaust holes 1122 are formed in the side surface is taken as an example, but any shape (for example, any shape such as a rectangle, an ellipse, or another polygon) can be used for any exhaust hole.
In addition, in the present embodiment, the structure in which one air vent hole is formed in each of the front surface and the side surface is taken as an example, but a plurality of air vent holes may be formed in each surface or any surface. For example, a plurality of small vent holes may be provided.
In the oxygen mask 1 of the present embodiment, the inhalation unit 111 is formed with a recess structure 1111 which is a reinforcing structure for reducing deformation of the inhalation unit due to external force and which is a structure for avoiding interference with eyeglasses when a user wears the eyeglasses. As described above, the air intake part 111 is formed in a shape that covers the bulge part of the nose as a whole, and at least a part of the bulge part is recessed inward, thereby forming the recess structure 1111.
The oxygen mask is made of resin or the like, has flexibility, and is relatively easily deformed (thereby improving the feeling of adhesion to the face to some extent), but if an undesirable deformation occurs, the adhesion to the face is rather impaired (an undesirable gap becomes large). Thus, there are problems as follows: oxygen supplied to the inhalation unit 111 leaks to the outside, or the partition function of the partition unit 114 is lowered and exhaled air enters the inhalation unit 111, and oxygen inhalation cannot be performed efficiently.
In contrast, according to the oxygen mask 1 of the present embodiment, since the concave structure 1111 reduces undesired deformation of the oxygen mask 1, it is possible to reduce a decrease in the efficiency of oxygen inhalation.
In addition, since interference with the glasses is reduced when the user wears the glasses, convenience of the user wearing the glasses is improved.
In the present embodiment, the two recessed portion structures 1111 are formed so as to have a function as an interference prevention structure with the eyeglasses at the same time, but the present invention is not limited thereto, and three or more recessed portion structures may be formed. In addition, when the function as the interference prevention structure with the eyeglasses is not provided, the recessed portion structure may be one.
Fig. 4A to 4E are views showing the oxygen supply tube connecting connector 12, in which fig. 4A is a perspective view, fig. 4B is a front view, fig. 4C is a rear view, fig. 4D is a side view, and fig. 4E is a sectional view.
The oxygen supply tube connecting connector (oxygen introducing part) 12 is a member for connecting an oxygen supply tube (not shown) to the oxygen mask 1, and as shown in fig. 4A to 4E, a cylindrical barrel part 121 is used as its basic form, and a connecting part 122 for connecting the oxygen supply tube is formed on the lower surface side of the barrel part 121. As described above, since the connector mounting hole 113 of the mask body 11 (the inhalation unit 111) is formed to open downward, the connection portion 122 connects the oxygen supply tube from the lower side of the mask body 11.
The cylindrical body 121 is formed to have an outer diameter substantially equal to an inner diameter of the connector mounting hole 113, and is formed with a flange 123. According to this configuration, the cylindrical body portion 121 is inserted into the connector mounting hole 113, and the flange 123 abuts against the cylindrical body portion, whereby the oxygen supply tube connecting connector 12 is mounted on the mask body portion 11.
The flow path changing member 125 is formed by forming an upper surface (horizontal plate) on the upper portion of the cylindrical body 121.
Further, the oxygen supply port 124 is opened in the lateral direction on the upper side surface of the cylindrical body 121.
Fig. 5 is a schematic diagram for explaining a use state of the oxygen mask 1 according to the present embodiment.
As can be understood from fig. 5, according to the oxygen mask 1 of the present embodiment, the exhaust holes 1121, 1122 are provided on the front and side surfaces of the exhalation module 112, so that the exhaled air is easily discharged to the outside of the mask body 11, and the intrusion of the exhaled air into the inhalation module 111 is reduced.
As described above, the recess structure 1111 reduces undesirable deformation of the oxygen mask 1, and the problem that the partition function of the partition portion 114 is lowered due to the deformation, and the exhaled air enters the inhalation portion 111 is also reduced.
Thus, according to the oxygen mask 1 of the present embodiment, the invasion of expired air into the inhalation unit 111 can be effectively reduced.
In the present embodiment, by attaching the oxygen supply tube connection connector 12 configured as described above to the mask body 11, as shown in fig. 5, the oxygen supply port 124 opens into the mask body 11 (inhalation unit 111) and oxygen (or concentrated oxygen) is supplied into the mask body 11 (inhalation unit 111).
As shown in fig. 5, by providing the flow path changing member 125 that changes the upward flow of oxygen supplied into the mask body 11, it is possible to suppress oxygen leakage from the gap in the upper portion of the mask (i.e., the vicinity of the back of the nose). Further, in a state where the oxygen supply tube connecting connector 12 is attached to the mask body 11, the lower end of the oxygen supply port 124 is formed along the upper surface of the partition portion 114, and the oxygen supply port 124 is formed to face the nose, so that an excellent effect of efficiently inhaling oxygen is also obtained. That is, the oxygen guided in the substantially horizontal direction by the flow path changing member 125 flows without being obstructed to the nose, and therefore has a function of efficiently sucking the supplied oxygen. As described earlier, undesired deformation of the oxygen mask 1 is reduced by the recess configuration 1111, and therefore the problem that this function is hindered by the deformation is also reduced.
In the present embodiment, the above-described operation is obtained by providing the flow path changing member 125 in the oxygen supply tube connecting connector 12, but the present invention is not limited to this, and any member for connecting the oxygen supply tube to the oxygen mask may be used as the oxygen supply tube connecting connector without providing the flow path changing member.
For example, in the present embodiment, the basic form of the connector for connecting an oxygen supply tube (oxygen introducing part) is a cylindrical shape, but the present invention is not limited thereto (for example, a polygonal prism or the like may be used).
In the present embodiment, the connector for connecting the oxygen supply tube (oxygen introducing portion) is formed as a separate body from the mask body portion, but the oxygen introducing portion may be formed integrally with the mask body portion.
In the present embodiment, the concave structure is provided in the inhalation unit as an example, but the concave structure may be provided in the exhalation unit, or both the inhalation unit and the exhalation unit may be provided with the concave structure.
