Description

Technical Field

[0001] The present invention relates to an oxygen inhalation device, particularly an oxygen direct inhalation and atomization device. Background Art

[0002] In the prior art, many patients with respiratory diseases need oxygen inhalation and atomization inhalation treatment due to their illness conditions.

[0003] When patients inhale oxygen, they usually use a nasal oxygen tube. When using the nasal oxygen tube, it is connected to the oxygen outlet tube of an oxygen inhaler, and normal saline is filled in a humidifying bottle. Oxygen enters the nasal oxygen tube after being moistened by the normal saline for the patient to inhale. However, when the patient needs to perform atomization inhalation treatment, oxygen does not need to be moistened, and the nurse needs to empty the normal saline in the humidifying bottle and then install an atomization mask. This process is very time-consuming.

[0004] Moreover, for the existing atomization masks, patients can only use them while sitting or with the head of the bed elevated, and cannot use them while lying flat. Because when the patient lies flat, the atomization bottle is in a horizontal state, and the liquid medicine in the atomization bottle will flow out. Therefore, it is urgent to develop an atomization mask that can be used both while sitting and while lying flat. Summary of the Invention

Detailed implementation manner

[0025] The embodiments of the present invention will be described in detail below. The examples of the embodiments are shown in the drawings, wherein the same or similar reference numerals represent the same or similar elements or elements with the same or similar functions throughout. The embodiments described below by referring to the drawings are exemplary and are only used to explain the present invention, and cannot be construed as a limitation to the present invention.

[0026] Embodiment of the present invention: As Figures 1 - 5 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 joint 3 and a second oxygen outlet joint 4. The atomizing mask assembly 2 is connected to the first oxygen outlet joint 3, and the nasal oxygen tube is connected to the second oxygen outlet joint 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 joint 3 or from the second oxygen outlet joint 4.

[0027] The nasal oxygen tube is a commercially available product and can be directly purchased. Since the present invention does not make improvements to the nasal oxygen tube, the structure of the nasal oxygen tube is not shown in the figure. After directly purchasing and connecting it to the second oxygen outlet joint 4, it can be used.

[0028] The present invention has a first oxygen outlet joint 3 and a second oxygen outlet joint 4. The air path switching structure is used to control the oxygen to flow out from the first oxygen outlet joint 3 or the second oxygen outlet joint 4. When the oxygen flows out through the first oxygen outlet joint 3, it does not pass through the physiological saline. Therefore, it is not necessary for nurses to handle the physiological saline in the humidifying bottle 5, which improves the work efficiency.

[0029] In a specific implementation manner, the oxygen inhaler assembly 1 includes a humidifying bottle 5, an inhaler housing 6, a flow meter 7, an oxygen input pipe 8, and a flow rate adjusting handwheel 9. The inhaler housing 6 is composed of a first circular pipe section, a second circular pipe section, and a third circular pipe section. The lower end of the first circular pipe section is fixedly connected to the top end of the second circular pipe section, and the lower end of the second circular pipe section is threadedly connected to the upper end of the third circular pipe section. The inner diameter of the first circular pipe section is larger than the inner diameter of the second circular pipe section, and the inner diameter of the third circular pipe section is larger than the inner diameter of the first circular pipe section.

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

[0031] The oxygen inlet pipe 8 is horizontally arranged. One end of the oxygen inlet pipe 8 is fixedly connected to the side wall of the first circular pipe section and the oxygen inlet pipe 8 is internally communicated with 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 inlet pipe 8. The internal threaded pipe 10 and the oxygen inlet pipe 8 are coaxially arranged. A valve rod 11 is fixedly provided on the flow rate adjusting handwheel 9. The outer wall of the valve rod 11 has threads, and the valve rod 11 is threadedly connected to the threaded pipe 10.

[0032] A limiting ring groove is formed on the outer wall of the oxygen inlet pipe 8. A limiting plate is also 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 for plugging and connecting with the quick interface of the oxygen pipeline on the ward wall. The two positioning pins 31 are used for plugging and matching with the positioning holes on the quick interface of the oxygen pipeline, so that the oxygen inhaler assembly 1 cannot rotate after being installed, playing a positioning role.

[0033] The flow meter 7 is fixedly installed at the top end of the first circular pipe section. The flow meter 7 is a prior art, and its specific structure will not be 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 rate adjusting handwheel 9 has anti-slip ridges, making the flow rate adjusting handwheel 9 easy to rotate.

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

[0035] Both the first oxygen outlet joint 3 and the second oxygen outlet joint 4 are fixedly provided on the side wall of the second circular pipe section. The first oxygen outlet joint 3 and the second oxygen outlet joint 4 are opposite and coaxially arranged. The first oxygen outlet joint 3 is communicated with the inner hole of the second circular pipe section. An air inlet hole 12 extending axially is formed inside the side wall of the second circular pipe section. The upper end of the air inlet hole 12 is communicated with the second oxygen outlet joint 4. The lower end opening of the air inlet hole 12 is located on the bottom surface of the second circular pipe section. The lower end of the air inlet hole 12 is communicated with the inner hole of the third circular pipe section.

[0036] Preferably, the outer walls of the first oxygen outlet joint 3 and the second oxygen outlet joint 4 are both stepped surfaces, which facilitates the installation of connecting hoses with different diameters and prevents the connecting hoses from loosening easily.

[0037] The inner wall of the third circular pipe section has threads, and the outer wall of the second circular pipe section has threads. The humidifying bottle 5 is threadedly connected to the lower end of the third circular pipe section, and the lower end of the second circular pipe section is threadedly connected to the upper end of the third circular pipe section.

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

[0039] The top surface of the air vent pipe 13 is higher than the top surface of the third circular pipe section. Preferably, sealing rings (not shown in the figure) are provided on the outer wall of the air vent pipe 13 and the circumferential wall of the gas baffle 14. When the top surface of the gas baffle 14 is below the intake end of the first oxygen outlet joint 3, oxygen enters the first circular pipe section through the oxygen input pipe 8. A part of the oxygen enters the flow meter 7, and the remaining oxygen flows into the interior of the second circular pipe section and then flows out along the inner hole of the first oxygen outlet joint 3.

[0040] When the air vent pipe 13 rises to a certain height, the outer wall of the air vent pipe 13 blocks the intake port of the first oxygen outlet joint 3. Oxygen enters the air vent pipe 13 through the air holes 18, flows out from the lower end of the air vent pipe 13 and enters the physiological saline. After being moistened by the physiological saline, it passes through the partition plate 15 through the through hole 19, and then enters the second oxygen outlet joint 4 through the intake hole 12 and flows out from the second oxygen outlet joint 4.

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

[0042] The atomizing bottle 21 is a prior art, and the internal structure and working principle of the atomizing bottle 21 will not be elaborated in this embodiment. The atomizing bottle 21 is used to hold the liquid medicine, and after oxygen is introduced, the liquid medicine is atomized. The atomized medicine enters the mask main body 20 through the corrugated pipe 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 main body 20, the other end of the first rod body is connected to one end of the second rod body, and an installation hole 26 is provided at the other end of the second rod body.

[0044] On the side surface of the second rod body facing the atomizing bottle 21, a plurality of first long convex blocks 27 are equidistantly arranged along the circumference of the installation hole 26. Two convex platforms 28 are fixedly provided on the outer wall of the atomizing bottle 21, and connecting screws 29 are fixedly provided on both of the two convex platforms 28. A hand-tightening nut 30 is threadedly connected to the connecting screw 29.

[0045] The connecting screw 29 is used for plug-in connection with the installation hole 26. In this embodiment, a plurality of second long convex blocks 32 are equidistantly arranged around the connecting screw 29 on the end surface of the convex platform 28. The cooperation between the second long convex blocks 32 and the first long convex blocks 27 can prevent the atomizing bottle 21 from shaking.

[0046] The working principle of the present invention: When a patient needs to use the nasal oxygen tube, connect the nasal oxygen tube to the second oxygen outlet joint 4, and rotate the flow rate adjustment handwheel 9 to adjust the appropriate oxygen flow rate according to the flow meter 7. Rotate the third circular tube section to make it rise. When the third circular tube section rises, the partition plate 15 and the air pipe 13 thereon rise simultaneously. When adjusted to the appropriate position, the top surface of the air pipe 13 is flush with the top surface of the second circular tube section. At this time, the air baffle 14 is located in the inner hole of the first circular tube section. Since the inner diameter of the inner hole of the first circular tube section is larger than the diameter of the air baffle 14, oxygen can pass through the air holes 18 through the end plate 17 and enter the air pipe 13, and then flow downward along the air pipe 13 and enter the humidifying bottle 5. In the humidifying bottle 5, it contacts with the physiological saline and gets humidified. The humidified oxygen rises and passes through the through holes 19 through the partition plate 15, and then flows along the air inlet hole 12 into the second oxygen outlet joint 4 and flows into the nasal oxygen tube.

[0047] When the patient needs to use the atomization mask instead of the nasal oxygen tube, connect the connecting hose 22 to the first oxygen outlet joint 3, and then rotate the third circular tube section to move it downward. As the third circular tube section moves downward, the partition plate 15, the ventilation pipe 13, and the air baffle 14 move downward synchronously. When adjusted to the appropriate position, the top surface of the air baffle 14 is lower than the intake end of the first oxygen outlet joint 3. At this time, the air baffle 14 blocks the oxygen, and the oxygen cannot enter the ventilation pipe 13, that is, the oxygen no longer enters the humidifying bottle 5. The oxygen directly enters the connecting hose 22 through the first oxygen outlet joint 3 and enters the atomization bottle 21 along the connecting hose 22. After the liquid medicine in the atomization bottle 21 is atomized, it enters the mask body 20 along the corrugated pipe 25.

[0048] To ensure the accuracy of each position adjustment, a first marking line and a second marking line can be set on the second circular tube section. The first marking line and the second marking line are not shown in the figure. The first marking line is above the second marking line. When the top surface of the third circular tube section aligns with the first marking line, the second oxygen outlet joint 4 outputs oxygen. When the top surface of the third circular tube section aligns with the second marking line, the first oxygen outlet joint 3 outputs oxygen.

[0049] Figure 1 The shown atomization mask assembly 2 is in the state when the patient stands or sits. When the patient needs to lie down and use the atomization mask, loosen the two hand-tightening nuts 30, rotate the atomization bottle 21 to make it in a vertical state, and then tighten the two hand-tightening nuts 30. The two brackets 23 clamp the two bosses 28 to prevent the atomization bottle 21 from swinging randomly. The adjusted state is referred to Figure 6 . The present invention solves the problem that the existing atomization mask cannot be used when lying flat.

[0050] The structure, features, and function effects of the present invention have been described in detail based on the embodiments shown in the drawings. The above is only the preferred embodiment of the present invention, but the present invention is not limited to the scope shown in the drawings. Any changes made according to the concept of the present invention, or equivalent embodiments modified into equivalent changes, still within the spirit covered by the description and the drawings, shall be within the protection scope of the present invention.
