Specific embodiments

[0021] In order to make the above objects, features and advantages of the present utility model more obvious and understandable, the specific embodiments of the present utility model will be described in detail below with reference to the accompanying drawings.

[0022] Secondly, the present utility model will be described in detail with reference to the schematic diagrams. When describing the embodiments of the present utility model in detail, for the convenience of explanation, the cross-sectional views showing the device structure will be enlarged locally not in accordance with the general scale, and the schematic diagrams are only examples, which should not limit the scope of protection of the present utility model here. In addition, in actual production, three-dimensional spatial dimensions including length, width and depth should be included.

[0023] In order to make the purpose, technical solution and advantages of the present utility model clearer, the embodiments of the present utility model will be further described in detail below with reference to the accompanying drawings.

[0024] Figures 1 - 4 Shown is the schematic diagram of the entire structure of a headset-type nasal oxygen tube of the present utility model. Please refer to Figures 1 - 4 , A headset-type nasal oxygen tube of this embodiment includes a cross-ear bracket 100. The two ends of the cross-ear bracket 100 have limit earrings 110 corresponding to the auricles. A gas collecting disc 200 is rotatably installed on the outer side of the end of at least one limit earring 110. One side of the gas collecting disc 200 is fixedly connected and communicated with a nasal oxygen tube bracket 300. The nasal oxygen tube bracket 300 is adjustable in angle. The end of the nasal oxygen tube bracket 300 away from the gas collecting disc 200 is fixedly connected and communicated with a nasal oxygen tube gas delivery pipe section 400. The side of the nasal oxygen tube gas delivery pipe section 400 that abuts against the patient's nose has two air holes 420 corresponding to the nostrils. There is also a nasal oxygen tube catheter 500 connected to the gas collecting disc 200.

[0025] On one side of the limit earring 110 connected to the air collecting disc 200, there is a rotating shaft 120, and the air collecting disc 200 is rotatably sleeved outside the rotating shaft 120. During use, the cross-ear bracket 100 is wound around the back of the head and hung on the ear through the limit earring 110, similar to an earphone hanger, which is simple and firm. Moreover, when the oxygen absorber needs to lie down and rest, the cross-ear bracket 100 can be directly rotated to the top of the head, avoiding the discomfort caused by the back of the head pressing on the bracket. And the air collecting disc 200 and the nasal oxygen tube bracket 300 can maintain the original wearing posture with the patient under the cooperation of the rotating shaft 120, with a simple structure and convenient operation. In addition, between the rotating shaft 120 and the air collecting disc 200, it can be a damping rotation, an externally provided locking screw, etc., as long as the stability after the structure adjustment can be maintained.

[0026] One side of the air collecting disc 200 has a first joint 210 for plugging and fixing the end of the nasal oxygen tube bracket 300, and one side of the bottom of the air collecting disc 200 also has a second joint 220 for plugging and fixing the nasal oxygen tube 500. In this embodiment, the air collecting disc 200 is a transfer joint of the nasal oxygen tube, and the nasal oxygen tube bracket 300 and the nasal oxygen tube 500 can be positioned and installed through the first joint 210 and the second joint 220. The installation method can be threaded connection, snap connection, plug-in connection, etc. This embodiment does not limit this, ensuring the convenience of use of the device. And the cross-ear bracket 100, the air collecting disc 200, the nasal oxygen tube bracket 300, and the nasal oxygen tube 500 of this earphone-type nasal oxygen tube are reusable, avoiding waste.

[0027] One end of the nasal oxygen tube bracket 300 has a tapered joint 310, and one end of the nasal oxygen tube air delivery section 400 also has an end sleeve 410 plugged outside the tapered joint 310, and the nasal oxygen tube air delivery section 400 is a closed structure at the opposite end of the end sleeve 410. Among them, the nasal oxygen tube air delivery section 400 is made of a hard material and is for single use. In this embodiment, the nasal oxygen tube air delivery section 400 can be made of, for example, plastic material, which is inexpensive. At the same time, to solve the problem of cross-infection when used by different people, when used for the second time, the end sleeve 410 at the end of the nasal oxygen tube air delivery section 400 can be directly pulled out from the tapered joint 310, and at the same time, a new nasal oxygen tube air delivery section 400 can be plugged in and replaced, which is simple and practical.

[0028] The nasal oxygen tube bracket 300 is an aluminum alloy gooseneck tube with an outer diameter of 5 mm, and a rubber layer is sleeved outside the aluminum alloy gooseneck tube. During use, due to the differences in the facial contours of different patients, in order to enable the nasal oxygen tube gas delivery section 400 to adapt to the facial contour and wearing angle under the support of the nasal oxygen tube bracket 300, a gooseneck tube is used as the main body of the nasal oxygen tube bracket 300, which can adjust the angle and extension range of the bracket pipeline according to actual needs and within a certain range, so that the nasal oxygen tube gas delivery section 400 can better fit the patient's nose. Moreover, the nasal oxygen tube bracket 300 has a certain elasticity and will not cause discomfort caused by the nasal oxygen tube gas delivery section 400 tightly attaching to the nose, ensuring both wearing comfort and the wearing stability of the nasal oxygen tube and preventing it from falling off.

[0029] On the outer side of the nasal oxygen tube gas delivery section 400, there are also two silica gel rings 430 corresponding to the outer periphery of the air holes 420 respectively. During use, the extended section of the traditional nasal oxygen tube inserted deep into the nasal cavity is removed from the nasal oxygen tube gas delivery section 400, and only the two air holes 420 need to be aligned with the nostrils. Moreover, the silica gel ring 430 on the outer periphery of the air hole 420 can form a certain semi-clutch contact with the nostrils, which not only ensures the docking stability between the air hole 420 and the nostrils, but also the silica gel ring 430 has a good skin-friendly effect and will not cause contact discomfort to the patient.

[0030] In summary, for the earphone-type nasal oxygen tube of this embodiment, during use, the cross-ear bracket 100 can be wound around the back of the head and hung on the ear through the limit earring 110, which is simple and firm; when the oxygen absorber needs to lie down and rest, the cross-ear bracket 100 can be directly rotated to the top of the head, avoiding the discomfort caused by the back of the head pressing on the bracket. In addition, the air collection tray 200 and the nasal oxygen tube bracket 300 can maintain the original wearing posture of the patient under the cooperation of the rotating shaft 120. Moreover, for the nasal oxygen tube gas delivery section 400, only the two air holes 420 need to be aligned with the nostrils, and the silica gel ring 430 on the outer periphery of the air hole 420 can form a certain semi-clutch contact with the nostrils, which not only ensures the docking stability between the air hole 420 and the nostrils, but also the silica gel ring 430 has a good skin-friendly effect.

[0031] Although the present invention has been described above with reference to the embodiments, various improvements can be made to it and components therein can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the various features in the embodiments disclosed in the present invention can be combined with each other in any way. The exhaustive description of these combinations is not given in this specification only for the sake of saving space and resources. Therefore, the present invention is not limited to the specific embodiments disclosed in the text, but includes all technical solutions falling within the scope of the claims.
