Description

Technical Field

[0001] The utility model belongs to the technical field of oxygen delivery equipment, in particular to an oxygen delivery device. Background Art

[0002] The Venturi mask is made according to the Venturi principle, that is, when oxygen enters the mask through a narrow channel, negative pressure is generated around the jet airflow, carrying a certain amount of air into the mask from the open edge. The size of the mask side seam changes the ratio of air to oxygen. Since the airflow injected into the mask is greater than the maximum flow rate and tidal volume when the patient inhales, the oxygen concentration is constant. Since the high-flow gas continuously flushes the inside of the mask, the exhaled air is difficult to be retained in the mask, so there is basically no rebreathing. In the treatment of patients with hypoxemia and hypercapnia, a Venturi mask needs to be selected, which can accurately control the oxygen concentration. Nebulization and oxygen inhalation are common clinical treatment methods. The oxygen nebulizer mask atomizes the liquid medicine and inhales it into the body along with the oxygen.

[0003] For critically ill patients who need oxygen, it is usually necessary to separately perform oxygen delivery through drug nebulization and oxygen delivery with adjusted oxygen concentration. Therefore, in clinical practice, oxygen nebulizer masks and Venturi masks are generally independent products. Different oxygen supply pipelines and masks need to be replaced back and forth in operation, which increases the workload of nurses, reduces work efficiency, and increases patient treatment costs.

[0004] Therefore, an oxygen delivery device with dual functions and the ability to quickly switch between two oxygen delivery modes is urgently needed. Utility Model Content

[0023] Example 1:

[0024] In this embodiment, an oxygen delivery device, such as Figure 1 As shown, it includes an oxygen mask 1, a first three-way valve 2, a second three-way valve 3, a first connecting pipe 4 and a second connecting pipe 5. Specifically, the first connecting pipe 4 and the second connecting pipe 5 are connected in parallel between the first three-way valve 2 and the second three-way valve 3. The third end of the first three-way valve 2 is connected to an external oxygen source, and the third end of the second three-way valve 3 is connected to the oxygen mask 1. The first connecting pipe 4 is provided with a Venturi valve 6, and the second connecting pipe 5 is provided with a nebulizer 7.

[0025] With this structure, by switching the connection direction of the first three-way valve 2 and the second three-way valve 3, the first connecting pipe 4 where the Venturi valve 6 is located or the second connecting pipe 5 where the nebulizer 7 is located is independently connected to the oxygen mask 1 and the external oxygen source, thereby realizing rapid switching between the two oxygen supply modes of liquid medicine atomization and oxygen concentration adjustment, improving work efficiency, integrating the two oxygen supply modes together, and using one tube for dual purposes. One oxygen mask 1 can realize two oxygen supply functions, saving material consumption, reducing treatment costs, and making the utility model more practical.

[0026] In this embodiment, the above-mentioned nebulizer 7 is an ultrasonic nebulizer cup, which has the advantages of high efficiency, speed and safety. It can convert the medicine into aerosol in a short time and flow along the oxygen to the above-mentioned oxygen mask 1. The aerosol particles are uniform in size and are easily absorbed by the lungs, quickly achieving a therapeutic effect. The ultrasonic nebulizer cup is an existing technology, so its specific structure and working principle will not be repeated again.

[0027] In this embodiment, Figure 1 As shown, the nebulizer 7 is provided with an air inlet and an air outlet. The air inlet is provided at the bottom of the nebulizer 7, and the air outlet is provided at one side of the nebulizer 7. Oxygen enters the nebulizer 7 through the air inlet and is fully mixed with the liquid medicine, and then is atomized into water mist by the ultrasonic atomizing sheet in the nebulizer 7 and transported to the oxygen mask 1 through the air outlet.

[0028] As an optimization, the above-mentioned atomizer 7 is provided with a dosing port 8, which is arranged at the top of the above-mentioned atomizer 7. The above-mentioned dosing port 8 is provided with a cover, and the atomized liquid can be conveniently injected into the atomizer 7 through the dosing port 8.

[0029] In this embodiment, Figure 1 As shown, a humidifier tank 9 is further included. The humidifier tank 9 is connected between the venturi valve 6 and the second three-way valve 3. The venturi valve 6 is used to mix the oxygen delivered from the external oxygen source into a certain amount of air, thereby providing oxygen with different concentration ratios according to the needs of the patient, and then flowing through the humidifier tank 9. The humidifier tank 9 is used to humidify and heat the oxygen flowing through, so that the humidity and temperature of the oxygen after treatment are more suitable for the human body, reducing the damage to the ciliary movement of the lung mucosa caused by the oxygen being too cold, thereby improving the rehabilitation effect.

[0030] Further, such as Figure 1 As shown, it also includes a humidification bottle 10, which is arranged between the first three-way valve 2 and the external oxygen source. The humidification bottle 10 is used to control and measure the oxygen flow to ensure the safety of oxygen supply. The external oxygen source is preferably an oxygen generator.

[0031] In this embodiment, the oxygen mask 1 is provided with a strap 11. The oxygen mask 1 has an air inlet pipe detachably connected to the second three-way valve 3. Compared with the traditional one-piece Venturi mask and the one-piece atomizing mask, the Venturi valve 6 of the Venturi mask and the atomizer 7 of the atomizing mask are separately arranged in a parallel structure, so that a common oxygen mask 1 can be shared, thereby reducing costs and eliminating the need for frequent replacement of oxygen supply lines and masks.

[0032] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any modifications or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection of the claims.
