[0002] In the prior art, many patients with respiratory diseases require oxygen inhalation and nebulized inhalation treatment due to their condition.

[0003] Patients usually use nasal oxygen cannula when breathing oxygen.

DETAILED DESCRIPTION

[0025] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be interpreted as limiting the present invention.

[0026] Embodiments of the present invention: Figure 1-Figure 5 As shown, an oxygen direct inhalation and atomization device includes an oxygen inhaler assembly 1, a nasal oxygen tube and an atomizing mask assembly 2. The oxygen inhaler assembly 1 is provided with a first oxygen outlet connector 3 and a second oxygen outlet connector 4. The atomizing mask assembly 2 is connected to the first oxygen outlet connector 3, and the nasal oxygen tube is connected to the second oxygen outlet connector 4. An air path switching structure is provided in the oxygen inhaler assembly 1, and the air path switching structure is used to control the oxygen to flow out from the first oxygen outlet connector 3 or the second oxygen outlet connector 4.

[0027] The nasal oxygen tube is a commercially available product and can be purchased directly. Since the present invention does not improve the nasal oxygen tube, the structure of the nasal oxygen tube is not shown in the figure. The nasal oxygen tube can be used after being purchased directly and connected to the second oxygen outlet connector 4.

[0028] The present invention has a first oxygen outlet connector 3 and a second oxygen outlet connector 4, and the oxygen outlet of the first oxygen outlet connector 3 or the second oxygen outlet connector 4 is controlled by an air path switching structure. When oxygen flows out through the first oxygen outlet connector 3, it does not pass through normal saline, so there is no need for nurses to handle the normal saline in the humidification bottle 5, thereby improving work efficiency.

[0029] In a specific embodiment, the oxygen inhaler assembly 1 includes a humidification bottle 5, an inhaler housing 6, a flowmeter 7, an oxygen input pipe 8 and a flow regulating handwheel 9. The inhaler housing 6 is composed of a first circular tube segment, a second circular tube segment and a third circular tube segment. The lower end of the first circular tube segment is fixedly connected to the top end of the second circular tube segment, the lower end of the second circular tube segment is threadedly connected to the upper end of the third circular tube segment, the inner diameter of the first circular tube segment is larger than the inner diameter of the second circular tube segment, and the inner diameter of the third circular tube segment is larger than the inner diameter of the first circular tube segment.

[0030] In this embodiment, the outer diameter of the first circular tube segment is smaller than the outer diameter of the second circular tube segment, and the outer diameter of the third circular tube segment is larger than the outer diameter of the second circular tube segment. The first circular tube segment and the second circular tube segment are integrally formed. The first circular tube segment, the second circular tube segment and the third circular tube segment are coaxial.

[0031] The oxygen input pipe 8 is arranged horizontally, one end of the oxygen input pipe 8 is fixedly connected to the side wall of the first circular pipe section and the oxygen input pipe 8 is communicated with the inside of the first circular pipe section. An internal threaded pipe 10 is also fixedly provided on the side wall of the first circular pipe section. The internal threaded pipe 10 is located on the opposite side of the oxygen input pipe 8. The internal threaded pipe 10 is coaxially arranged with the oxygen input pipe 8. A valve stem 11 is fixedly provided on the flow regulating handwheel 9. The outer wall of the valve stem 11 has threads, and the valve stem 11 is threadedly connected to the threaded pipe 10.

[0032] A limiting annular groove is formed on the outer wall of the oxygen inlet pipe 8, and a limiting plate is fixedly provided on the oxygen inlet pipe 8. Two positioning pins 31 are fixedly provided on the limiting plate. The oxygen inlet pipe 8 is used to be plugged and connected with the oxygen pipeline quick interface on the wall of the ward. The two positioning pins 31 are used to be plugged and matched with the positioning holes on the oxygen pipeline quick interface, so that the oxygen inhaler assembly 1 cannot rotate after installation, thereby playing a positioning role.

[0033] The flow meter 7 is fixedly mounted on the top of the first circular pipe section. The flow meter 7 is a prior art, and its specific structure is not described in detail in this embodiment. The present invention does not improve the structure of the flow meter 7. The outer wall of the flow regulating hand wheel 9 has anti-slip convex strips to facilitate the rotation of the flow regulating hand wheel 9.

[0034] When the flow regulating hand wheel 9 is rotated by hand, since the valve stem 11 is threadedly connected to the threaded tube 10, the valve stem 11 moves along the axial direction of the threaded tube 10. The end of the valve stem 11 located inside the inhaler housing 6 is a conical end. When the end of the valve stem 11 approaches the oxygen inlet pipe 8, the oxygen flow rate gradually decreases. When the end of the valve stem 11 completely blocks the outlet end of the oxygen inlet pipe 8, the oxygen is cut off. When the valve stem 11 gradually moves away from the oxygen inlet pipe 8, the oxygen flow rate gradually increases to the maximum flow rate.

[0035] The first oxygen outlet connector 3 and the second oxygen outlet connector 4 are both fixed on the side wall of the second circular tube segment. The first oxygen outlet connector 3 and the second oxygen outlet connector 4 are opposite and coaxially arranged. The first oxygen outlet connector 3 is connected to the inner hole of the second circular tube segment. An air inlet hole 12 extending axially is formed in the side wall of the second circular tube segment. The upper end of the air inlet hole 12 is connected to the second oxygen outlet connector 4. The lower end opening of the air inlet hole 12 is located on the bottom surface of the second circular tube segment. The lower end of the air inlet hole 12 is connected to the inner hole of the third circular tube segment.

[0036] Preferably, the outer walls of the first oxygen outlet connector 3 and the second oxygen outlet connector 4 are both stepped surfaces, so that it is convenient to install connecting hoses of different diameters and the connecting hoses are not easy to get loose.

[0037] The inner wall of the third circular tube segment is threaded, the outer wall of the second circular tube segment is threaded, the humidification bottle 5 is threadedly connected to the lower end of the third circular tube segment, and the lower end of the second circular tube segment is threadedly connected to the upper end of the third circular tube segment.

[0038] The air path switching structure includes a vent pipe 13, an air baffle 14, a partition 15 and a connecting column 16. The partition 15 is arranged horizontally and fixedly arranged on the inner wall of the third circular tube segment. The partition 15 should be arranged at a middle and lower position in the third circular tube segment so that the upper space of the partition 15 is larger than the lower space of the partition 15. The vent pipe 13 runs through the partition 15 and is fixedly connected thereto. The vent pipe 13 is coaxial with the partition 15. The outer diameter of the vent pipe 13 is equal to the inner diameter of the second circular tube segment. The top end of the vent pipe 13 has an end plate 17. The air baffle 14 is fixedly connected to the end plate 17 through the connecting column 16. The air baffle 14 is a circular plate. The diameter of the air baffle 14 is equal to the outer diameter of the vent pipe 13. The end plate 17 is provided with a plurality of air holes 18. The partition 15 is provided with a through hole 19.

[0039] The top surface of the ventilation pipe 13 is higher than the top surface of the third circular pipe segment. Preferably, sealing rings (not shown in the figure) are provided on the outer wall of the ventilation pipe 13 and the circumferential wall of the air baffle plate 14. When the top surface of the air baffle plate 14 is located below the air inlet end of the first oxygen outlet connector 3, oxygen enters the first circular pipe segment through the oxygen input pipe 8, part of the oxygen enters the flowmeter 7, and the rest of the oxygen flows into the second circular pipe segment and then flows out along the inner hole of the first oxygen outlet connector 3.

[0040] When the ventilation tube 13 rises to a certain height, the outer wall of the ventilation tube 13 blocks the air inlet of the first oxygen outlet connector 3, and oxygen enters the ventilation tube 13 through the air hole 18, flows out from the lower end of the ventilation tube 13 and enters the physiological saline. After being moistened by the physiological saline, it passes through the partition 15 through the through hole 19, and then enters the second oxygen outlet connector 4 through the air inlet 12 and flows out from the second oxygen outlet connector 4.

[0041] Furthermore, the atomizing mask assembly 2 includes a mask body 20, an atomizing bottle 21 and a connecting hose 22. Two brackets 23 are fixedly provided on the outer wall of the mask body 20. The atomizing bottle 21 is rotatably installed between the two brackets 23. A hose connector 24 is provided at the bottom of the atomizing bottle 21. The hose connector 24 is connected to the first oxygen outlet connector 3 through the connecting hose 22. A bellows 25 is provided on the side wall of the upper end of the atomizing bottle 21. The other end of the bellows 25 is connected to the mask body 20.

[0042] The atomizer bottle 21 is a prior art, and the internal structure and working principle of the atomizer bottle 21 are not described in detail in this embodiment. The atomizer bottle 21 is used to hold medicine solution, and the medicine solution is atomized after oxygen is introduced. The atomized medicine enters the mask body 20 through the bellows 25.

[0043] The two brackets 23 have the same structure and are both composed of a first rod body and a second rod body. The length of the first rod body is greater than that of the second rod body. One end of the first rod body is fixedly connected to the mask body 20, and the other end of the first rod body is connected to one end of the second rod body. The other end of the second rod body is provided with a mounting hole 26.

[0044] A plurality of first long protrusions 27 are provided at equal intervals along the circumference of the mounting hole 26 on the side of the second rod body facing the atomizer bottle 21. Two bosses 28 are fixed on the outer wall of the atomizer bottle 21. Connecting screws 29 are fixed on the two bosses 28. Hand nuts 30 are threadedly connected to the connecting screws 29.

[0045] The connecting screw 29 is used for plugging and connecting with the mounting hole 26. In this embodiment, a plurality of second long protrusions 32 are arranged at equal intervals around the connecting screw 29 on the end surface of the boss 28. The second long protrusions 32 cooperate with the first long protrusions 27 to prevent the atomizer bottle 21 from shaking.

[0046] The working principle of the present invention is as follows: when the patient needs to use the nasal oxygen tube, the nasal oxygen tube is connected to the second oxygen outlet connector 4, and the flow regulating hand wheel 9 is rotated to adjust the appropriate oxygen flow according to the flow meter 7. The third circular tube segment is rotated to make it rise, and when the third circular tube segment rises, the partition 15 and the ventilation tube 13 thereon rise at the same time. When adjusted to a suitable position, the top surface of the ventilation tube 13 is flush with the top surface of the second circular tube segment. At this time, the air baffle 14 is located in the inner hole of the first circular tube segment. Since the inner hole diameter of the first circular tube segment is larger than the diameter of the air baffle 14, oxygen can enter the ventilation tube 13 through the air hole 18 through the end plate 17, and then flow downward along the ventilation tube 13 and enter the humidification bottle 5, contact and moisten with the physiological saline in the humidification bottle 5, and the moistened oxygen rises and passes through the partition 15 through the through hole 19, and then enters the second oxygen outlet connector 4 along the air inlet 12 and flows into the nasal oxygen tube.

[0047] When the patient does not use the nasal oxygen tube and needs to use the atomizing mask, the connecting hose 22 is connected to the first oxygen outlet connector 3, and then the third circular tube section is rotated to move downward. As the third circular tube section moves downward, the partition 15, the ventilation tube 13 and the air baffle 14 move downward synchronously. When adjusted to a suitable position, the top surface of the air baffle 14 is lower than the air inlet end of the first oxygen outlet connector 3. At this time, the air baffle 14 blocks the oxygen, and the oxygen cannot enter the ventilation tube 13, that is, the oxygen no longer enters the humidification bottle 5. The oxygen directly enters the connecting hose 22 through the first oxygen outlet connector 3, and enters the atomizing bottle 21 along the connecting hose 22. After the liquid medicine in the atomizing bottle 21 is atomized, it enters the mask body 20 along the corrugated tube 25.

[0048] In order to ensure the accuracy of each position adjustment, a first identification line and a second identification line can be set on the second circular tube segment. The first identification line and the second identification line are not shown in the figure. The first identification line is located above the second identification line. When the top surface of the third circular tube segment is aligned with the first identification line, the second oxygen outlet connector 4 outputs oxygen. When the top surface of the third circular tube segment is aligned with the second identification line, the first oxygen outlet connector 3 outputs oxygen.

[0049] Figure 1 The atomizer mask assembly 2 shown is in the state when the patient is standing or sitting. When the patient needs to lie down to use the atomizer mask, loosen the two hand nuts 30, rotate the atomizer bottle 21 to make it in a vertical state, and then tighten the two hand nuts 30. The two brackets 23 clamp the two bosses 28 so that the atomizer bottle 21 will not swing at will. Figure 6 The present invention solves the problem in the prior art that the atomizing mask cannot be used when lying flat.

[0050] The above describes in detail the structure, features and effects of the present invention based on the embodiments shown in the drawings. The above is only a preferred embodiment of the present invention, but the present invention is not limited to the scope of implementation shown in the drawings. Any changes made according to the concept of the present invention, or modifications to equivalent embodiments with equivalent changes, which still do not exceed the spirit covered by the description and drawings, should be within the protection scope of the present invention.
