Therefore, it is possible to suppress the occurrence of oral troubles in the patient.

In addition, since the inner side of the bent portion 112 of the bent tube 11 of the outflow portion 10 that supplies the oral humidified gas is supported by the corner of the patient's mouth by the fixing portion 70, the outflow portion 10 can be prevented from being detached from the patient, and the outflow portion 10 can be prevented from coming off from the patient. In addition, the humidifying gas for the oral cavity can be supplied to a part which is difficult to humidify, such as around the patient's gums. Further, a pair of tubes 61 and outflow portions 10 are provided, and each outflow portion 10 is fixed near the right and left corners of the patient's mouth, so that oral humidifying gas can be supplied from two directions into the patient's oral cavity. Further, since the oral cavity humidifying gas can be supplied from two directions, even if one of the tubes 61 or the outflow part 10 is blocked, the oral cavity humidifying gas can be supplied. Furthermore, since the outflow part 10 is fixed near the right and left corners of the patient's mouth, it is possible to prevent the patient's eating, drinking and talking from being disturbed.

In addition, since the two slots 131 of the plate-like portion 13 are formed in parallel with the base end portion 111 of the bending tube 11, by inserting the fixing portion 70 through the two slots 131, the extension direction of the fixing portion 70 is adjusted. The outflow part 10 can be movably supported, and its position can be changed according to the size and shape of the patient's face, and the supply tool can be securely fixed to the left and right of the chin below the corner of the patient's mouth. Further, since the proximal end portion 111 is supported by the arc-shaped wall 132 of the plate-like portion 13 so as to be freely rotatable in the circumferential direction, the distal end of the bending tube 11 (the distal end of the bending portion 112) can be inserted into the oral cavity of the patient. It can be done easily.

In the first embodiment described above, the oral humidifying gas is supplied into the oral cavity of the patient from the tip of the bending tube 11 (the tip of the bending portion 112). ) may be formed with a plurality of holes. In this case, even if the distal end of the bending tube 11 is blocked, the oral cavity humidifying gas can be supplied from the plurality of holes formed in the side surface, and the oral cavity humidifying gas can be diffused in the oral cavity.
Further, in the first embodiment, the tip of the bending tube 11 of the outflow part 10 is inserted into the oral cavity of the patient. It may be configured to

Further, the tip of the extending portion 113 is formed in an arc shape that changes the direction of circulation of the oral moistening gas flowing through the extending portion 113 . That is, the injection port 114 of the outflow portion 10A opens in a direction intersecting the length direction of the extending portion 113, that is, in a direction intersecting the plane formed by the bent portion 112A.

Therefore, the oral cavity humidifying gas flowing through the connection portion 12, the base end portion 111, and the bending portion 112A flows through the distal end of the extension portion 113, thereby increasing the corners of the mouth of the patient when the outflow portion 10A is attached to the patient. directed to the side. When the outflow part 10A is arranged on the right and left sides of the chin below the corners of the patient's mouth in this way, when the oral humidifying gas is supplied through the connecting part 12, the humidifying gas for the oral cavity is supplied from the injection port 114 to the vicinity of the corners of the patient's mouth. Gas escapes and is delivered to the patient.

In the oral humidifying gas supplier 100A according to the modified example of the first embodiment, the bendable tube 11 is not inserted into the patient's oral cavity, so the patient's discomfort can be eliminated, and the patient's eating and talking can be improved. can be suppressed. In addition, since the oral cavity humidifying gas flows out to the vicinity of both corners of the mouth of the patient, the oral cavity humidifying gas can be reliably supplied into the oral cavity. Also, by rotating the base end portion 111A in its circumferential direction, the distance between the injection port 114 and the patient's lips can be changed, and the oral cavity humidifying gas can be supplied to a more appropriate position.

With such a configuration, the oral cavity humidifying gas supplied from each tube 61 flows through the introduction tube 31 to the insertion tube 32 and flows out from the injection port 321 . Such an insertion tube 32 is made of resin such as soft PVC so as not to damage the tooth even if the patient accidentally chews on it.

The contact portion 33 is made of an easily bendable resin such as soft PVC. The abutting portion 33 is a portion that extends in an arc shape toward both sides from the connecting portion of the introduction tube 31 and the insertion tube 32, and has a shape that increases in width toward both sides. Two longitudinally extending slots 331 are formed on both sides of the contact portion 33, and these slots 331 are formed in parallel. A fixing portion 70C made of an elastic band is inserted through each of these slots 331 .

A first opening 333 is formed inside the slot 331 , and a second opening 334 is formed inside the first opening 333 . The inner end of the second opening 334 extends to the vicinity of the joint between the introduction tube 31 and the insertion tube 32 . The first opening 333 and the second opening 334 are used to reduce the weight of the contact portion 33, to suppress stuffiness when the contact portion 33 contacts the patient's cheek, and to block the patient's oral cavity. provided to prevent

Further, as shown in FIG. 12, the contact portion 33 is formed in such a shape that the contact surface that contacts the patient's cheek is inside, and the surface opposite to the contact surface protrudes outward. A covering portion 332 that covers the connecting portion between the introduction tube 31 and the insertion tube 32 is formed in the central portion of the surface of the contact portion 33 opposite to the contact surface. On the other hand, the tip of the insertion tube 32 protrudes from the contact surface of the contact portion 33, and the length thereof is set to 11.5 mm, for example.

A tube 61 (not shown) is connected to the introduction tube 31 of the outflow part 10C configured as described above, and the oral humidified gas supply device 100C is attached to the fixed part 70 with the insertion tube 32 inserted into the oral cavity of the patient. fixed to the patient by Then, the humidified gas for oral cavity is supplied from the heating humidifier to the outflow part 10C through each tube 61, passes through the internal flow paths of the introduction tube 31 and the insertion tube 32, and is directed from the injection port 321 into the oral cavity of the patient. supplied by

In this embodiment, the oral cavity humidifying gas flowing from the introduction tube 31 can be reliably supplied into the patient's oral cavity from the insertion tube 32 inserted into the patient's oral cavity. Further, since the outflow portion 10C is fixed with the contact portion 33 in contact with the patient's cheek, it is possible to reliably prevent the outflow portion 10C from being detached from the patient's mouth. In addition, since the insertion tube 32 is inclined upward as it extends away from the connection site with the introduction tube 31, the oral cavity humidifying gas can be supplied into the patient's oral cavity along the upper jaw, which tends to dry out more easily. The occurrence of oral troubles can be further suppressed.

[Modified example of the third embodiment]
FIG. 14 is a perspective view showing an oral humidifying gas supply tool 100D according to a modification of the third embodiment. In the following description, the same or substantially the same configurations as those of the third embodiment are given the same numbers, and descriptions thereof are omitted or simplified.
In the third embodiment, the length of the insertion tube 32 protruding from the contact surface of the contact portion 33 is 10 mm to 13 mm, but the length is not limited to this.
In the oral humidifying gas supplier 100D of this modified example, the length of the insertion tube 32D is set to be as short as 3 mm to 6 mm. Also, the injection port 321D of the insertion tube 32D is formed in an elliptical shape in plan view. This is because the length of the insertion tube 32D protruding from the contact surface is as short as 3 mm to 6 mm, so that even if the insertion tube 32D is inserted into the oral cavity of the patient, the possibility of the patient chewing is low.

In this modification, since the length of the insertion tube 32D protruding from the contact surface of the contact portion 33 is as small as 3 mm to 6 mm, it is not inserted deep into the oral cavity of the patient, thereby reducing patient discomfort. .

Moreover, the present invention is not limited to the above embodiments, and various modifications can be made without departing from the scope of the present invention.
For example, in each of the embodiments described above, two tubes 61 are provided, but the configuration is not limited to this, and may be a configuration in which only one tube 61 is provided. In this case, in the first embodiment, only either the left or right outflow portion 10, 10A is attached to the patient. That is, the number of tubes 61 and outflow portions 10 and 10A is not limited to two. Further, in the second embodiment, it may be connected to either the left or right bending tube 231 . In addition, in the third embodiment, it is sufficient that one tube 61 is connected to the introduction tube 31 .
