Description

Technical Field

[0001] This utility model relates to the field of portable oxygen concentrators, and more particularly to an oxygen inhalation nozzle. Background Technology

[0002] Portable oxygen concentrators and portable oxygen cylinders have become essential equipment for high-altitude travel, outdoor activities, and daily medical needs due to their lightweight nature and stable battery life.

[0003] Existing portable oxygen concentrators are generally pulse-type, requiring a nasal cannula to connect the concentrator's outlet to the user's nose. Once powered on, the concentrator continuously delivers oxygen based on the user's breathing feedback. However, current nasal cannulas are typically over 1 meter long, severely hindering movement and potentially causing safety issues. Furthermore, the need for insertion and preparation before use makes rapid oxygen intake difficult.

[0004] Existing portable oxygen cylinders spray oxygen directly into the mouth or nose after the user presses the corresponding button, without the need for a nasal cannula. They mainly use a mask for oxygen delivery. The mask has a large internal space, and the oxygen flow is relatively diffuse when it enters the mouth and nose from the oxygen cylinder, resulting in low oxygen utilization and a low flow rate. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide an oxygen mouthpiece for achieving rapid oxygen inhalation.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: An oxygen inhalation nozzle is integrated into a handheld oxygen concentrator and is used to contact the mouth or nose for oxygen delivery; a cover is included, with an outwardly extending oxygen inhalation section and an oxygen outlet; and branch pipes are included, each branch pipe consisting of a main pipe for connecting to the handheld oxygen concentrator and branch pipes extending to the oxygen outlet, the inner diameter of the main pipe being larger than the inner diameter of the branch pipes. In actual use, when the user needs oxygen, they simply pick up the handheld oxygen concentrator and bring the cover close to their mouth or nose, allowing the oxygen outlet of the inhalation section to enter their mouth or nose, and oxygen use can begin. The entire process from needing oxygen to using oxygen eliminates the cumbersome wearing process of traditional nasal cannulas, conveniently achieving rapid oxygen use. When the user no longer needs oxygen, they simply move the handheld oxygen concentrator away from their mouth or nose, eliminating the need to remove the nasal cannulas and greatly improving the user experience. Furthermore, because the inner diameter of the main tube of the oxygen inhaler is larger than that of the branch tube, when oxygen enters the branch tube from the main tube, the diameter of the oxygen flow becomes smaller, and the gas pressure increases. This increased gas pressure allows for a significant increase in the gas flow rate at the outlet of the branch tube. Ultimately, the oxygen discharged from the outlet of the branch tube will be ejected in a distinct jet-like motion along the direction of the outlet. Users simply need to place their mouth or nose in the direction of the oxygen jet, allowing the high concentration of oxygen to directly enter their mouth or nose, improving oxygen utilization and effectiveness, and enabling a faster increase in the user's blood oxygen saturation level.

[0007] To achieve better oxygen injection, the following optimal configuration can be adopted: the ratio of the main trachea's inner diameter to the branch trachea's inner diameter should be greater than 2. By increasing the ratio of the main trachea's inner diameter to the branch trachea's inner diameter, the oxygen injection rate at the branch trachea's outlet can be significantly increased, thereby further enhancing the oxygen concentration during rapid oxygen inhalation.

[0008] As one embodiment of the branch tube structure, the following configuration can be selected: There are two branch tubes, symmetrically arranged on both sides of the main trachea along its axis. The branch tubes' distribution on both sides of the main trachea facilitates placement of the two branch tubes into the patient's two nostrils during use. Simultaneously, the branch tubes' location on both sides of the main trachea allows for a more even distribution of oxygen within the main trachea into the branch tubes on both sides.

[0009] Furthermore, to allow the branch tube to be better inserted into the user's nostrils, the following design can be chosen: the axis of the branch tube is obliquely positioned to intersect the axis of the main trachea, forming a Y-shape. This Y-shape allows the outlet of the branch tube to be closer to the user's nostrils, while also facilitating the smooth flow of oxygen from the main trachea into the branch tube, significantly reducing the resistance encountered by oxygen as it flows from the main trachea into the branch tube, thus ensuring the oxygen flow rate.

[0010] To facilitate easy installation and removal of the mask and branch tubing, the following solution can be chosen: the mask and branch tubing are connected via a detachable connection structure. When the mask needs to be replaced in the future, simply separate the mask from the branch tubing, and the new mask can be easily installed and secured to the branch tubing.

[0011] Furthermore, the preferred detachable connection structure includes a positioning boss at the bottom of the mask and a port at the top of the main air tube, with the positioning boss snapping into the port. By engaging the positioning boss with the port at the top of the main air tube, the mask can be quickly positioned on the main air tube. Simultaneously, the positioning boss can block the port at the top of the main air tube, allowing oxygen from the main air tube to be ejected through the branch pipe.

[0012] Furthermore, the preferred detachable connection structure includes a branch pipe clip, which is positioned around the outer edge of the branch pipe outlet. The inner wall of the oxygen inhalation section has a groove that matches the branch pipe clip, and the branch pipe clip is engaged within this groove. This engagement between the branch pipe clip and the groove facilitates convenient fixing and disassembly of the oxygen inhalation section from the branch pipe.

[0013] To allow the oxygen inhalation part of the mask to adapt to the differences in the distance between the nostrils of different users, the material of the mask can be made of flexible materials, such as silicone or fluorosilicone. This allows the oxygen inhalation part to deform to a certain extent during use, adjusting the distance between the oxygen outlets to a position suitable for the distance between the user's nostrils.

[0014] In actual use, air holes can be set on the cover to connect the inside of the cover with the outside, so as to expel the gas exhaled by the user and retained inside the cover in a timely manner.

[0015] The beneficial effects of this utility model are: 1. By integrating the oxygen mouthpiece into a handheld oxygen concentrator, the entire process from needing oxygen to receiving it eliminates the cumbersome wearing process of traditional nasal cannulas, conveniently enabling rapid oxygen use. The mouthpiece moves with the handheld oxygen concentrator to the mouth and nose for contact oxygen delivery, and the handheld oxygen concentrator can be easily removed after use, allowing for immediate use. This is especially suitable for intermittent oxygen use scenarios with short durations but high frequency.

[0016] Second, by making the inner diameter of the main trachea larger than that of the branch trachea, the oxygen pressure in the branch trachea is effectively increased, the oxygen flow rate from the outlet of the branch trachea is higher, the oxygen near the outlet of the branch trachea is more concentrated, the amount of oxygen directly entering the mouth and nose is increased, the oxygen utilization efficiency is increased, and the user's blood oxygen concentration level can be quickly improved.

[0017] Third, the branch pipes are symmetrically arranged on both sides of the main trachea along the axis of the main trachea. The branch pipes and the main trachea form a Y-shaped structure, which facilitates the smooth flow of oxygen from the main trachea into the branch pipes, greatly reduces the resistance encountered by oxygen when flowing from the main trachea into the branch pipes, and ensures the flow rate of oxygen.

[0018] Fourth, the branch air tube and the mask are detachably connected, allowing for convenient mask replacement. In actual use, multiple people can share the same oxygen concentrator. When using oxygen, simply attach your corresponding mask to the branch air tube to receive oxygen. This not only ensures the safety and hygiene of oxygen use but also improves the utilization efficiency of the oxygen concentrator.

[0019] This invention is particularly applicable to handheld oxygen concentrators. Attached Figure Description

[0025] The present invention will be further described below with reference to the accompanying drawings.

[0026] like Figures 1 to 4The oxygen inhalation nozzle shown mainly consists of a main air pipe 2, a branch pipe 21, and a cover 1. The main air pipe 2 is a hollow oxygen delivery pipe. In actual use, the inlet at the bottom of the main air pipe 2 is connected to the oxygen outlet of the handheld oxygen concentrator 3, thereby delivering oxygen from the oxygen storage tank of the handheld oxygen concentrator 3 to the oxygen inhalation nozzle, and then guiding oxygen to the user's mouth or nose through the oxygen inhalation nozzle. In actual use, the oxygen outlet 11 of the cover 1 is brought into contact with the user's nose or mouth to deliver oxygen. When not in use, it is directly separated and integrated into the handheld oxygen concentrator 3, allowing the oxygen inhalation nozzle to be moved to the oxygen inhalation point while holding it with one hand, realizing a convenient and readily available usage mode. A positioning protrusion 13 of the cover 1 is provided inside the port 23 at the top of the main air pipe 2. The positioning protrusion 13 is located at the bottom of the cover 1. After the positioning protrusion 13 is engaged with the port at the top of the main air pipe 2, it can achieve positioning between the cover 1 and the main air pipe 2. At the same time, the positioning protrusion 13 can also seal the port 23 at the top of the main air pipe 2, allowing all the oxygen in the main air pipe 2 to be output through the branch pipe 21 connected to the main air pipe 2. There are two branch pipes 21, which are symmetrically arranged on both sides of the main air pipe 2 along the axis of the main air pipe 2. The axis of the branch pipe 21 is obliquely arranged with the axis of the main air pipe 2, ultimately forming a Y-shaped structure with the main air pipe 2. When oxygen is used in real time, oxygen enters the main air pipe 2 from the handheld oxygen concentrator 3, and then the oxygen is evenly distributed to the branch pipes 21 on the left and right sides of the main air pipe 2. Among them, such as Figure 2 As shown, the inner diameter D of the main trachea 2 is larger than the inner diameter d of the branch trachea 21. This increases the oxygen pressure after oxygen enters the branch trachea 21 from the main trachea 2, thereby increasing the oxygen flow rate at the outlet of the branch trachea 21. This allows the user to increase their oxygen intake in a short time and rapidly improve their blood oxygen saturation level. Preferably, to ensure the oxygen flow rate at the outlet of the branch trachea 21, the ratio of the inner diameter D of the main trachea to the inner diameter d of the branch trachea can be set to be greater than 2.

[0027] A pair of oxygen inhalation sections 14 are provided on the top of the mask body 1, each with an oxygen outlet 11. The outer contour of the oxygen inhalation section 14 is adapted to the shape of the nostrils, facilitating contact between the oxygen inhalation section 14 and the nostrils during use. In this embodiment, the outer contour of the oxygen inhalation section 14 can be a gradually narrowing funnel shape, and the oxygen outlet 11 is located at the outlet of the funnel. The air vents 12 provided on the mask body 1 connect the interior of the mask body 1 with the outside, thereby allowing the air exhaled by the user to be discharged in a timely manner. At the same time, the direction of the oxygen outlet 11 is consistent with the direction of the air outlet of the branch pipe 21, ensuring that the direction of the oxygen sprayed from the air outlet of the branch pipe 21 is towards the user's mouth or nose. The oxygen inhalation section 14 is fixed to the base of the mask body 1. The base of the mask body 1 is shaped like a mask body and forms an inner cavity. The base of the mask body 1 covers the main air pipe 2 and the branch pipe 21 inside the inner cavity. The aforementioned positioning boss 13 is provided in the middle part of the base of the cover body 1. The positioning boss 13 protrudes downward along the wall of the base of the cover body 1 and is provided and fixed in the port at the top of the main air pipe 2.

[0028] Based on this, such as Figure 1 and Figure 3 As shown, a branch pipe buckle 22 is also provided on the outer edge of the air outlet of the branch pipe 21. The branch pipe buckle 22 protrudes along the direction perpendicular to the axis of the branch pipe 21 and is arranged in a circle around the circumference of the air outlet of the branch pipe 21. The branch pipe buckle 22 is engaged and matched with the groove on the inner wall of the oxygen inhalation part 14. The branch pipe buckle 22 is engaged and set in the groove, so that the axis of the oxygen outlet 11 is coaxial with the axis of the air outlet of the branch pipe 21. In actual use, this design ensures that the oxygen sprayed from the air outlet of the branch pipe 21 can pass through the oxygen outlet 11 in a straight line without obstruction and continue to enter the user's mouth or nose directly in a straight line. Of course, when the user chooses not to insert the oxygen outlet 11 into their mouth or nose, since the outlet direction of the branch tube 21 is consistent with the outlet direction of the oxygen outlet 11, the user can also aim the oxygen outlet 11 at their nose or mouth, keeping the oxygen outlet 11 close to their nose or mouth but not in direct contact, so that the oxygen outlet 11 sprays oxygen into their nose or mouth. This is especially suitable for scenarios where the handheld oxygen concentrator 3 is in oxygen spray mode, improving the convenience of oxygen use. Due to the high speed of the sprayed oxygen, a sufficient oxygen supply can also be obtained. The mask 1 can be made of flexible materials, such as silicone or fluorosilicone. Similarly, the main air tube 2 and the branch tube 21 can also be made of flexible materials such as silicone or fluorosilicone. The flexible material allows the mask 1 and the oxygen inhalation part 14 to deform when in contact with the oxygen inhalation part.
