Description

Technical Field

[0001] This utility model belongs to the field of portable medical oxygen supply technology, specifically relating to a nasal oxygen tube with oxygen output detection function. Background Technology

[0002] Currently, commercially available portable medical oxygen concentrators offer both oral and nasal oxygen delivery methods. Nasal-operated portable oxygen concentrators require a nasal cannula for use. Because portable medical oxygen concentrators have limited oxygen storage capacity, it's generally desirable to use them at a lower oxygen flow rate to reduce oxygen waste from high-flow-rate outputs and extend the duration of use. However, since portable medical oxygen concentrators are often disposable, adding a complex, dedicated low-flow-rate oxygen monitoring system is prohibitively expensive and unsuitable for their application scenarios. Therefore, to address these issues, it is necessary to design a simple, low-cost, and easy-to-use nasal cannula with oxygen delivery detection functionality. Utility Model Content

[0003] The technical problem solved by this utility model is to provide a nasal oxygen tube with oxygen output detection function. By setting a float-type oxygen output detection device between the oxygen hose and the oxygen inlet connector, the oxygen output status of the oxygen flowing into the oxygen hose is detected by the float-type oxygen output detection device. This solves the problem that traditional portable oxygen supply devices cannot determine the oxygen delivery status at low flow rates. It provides detection conditions for extending the oxygen supply time by using low flow rate oxygen output, which helps to reduce the oxygen waste caused by high flow rate oxygen output and achieve the purpose of saving oxygen. The structure is simple, the design is novel and reasonable, and the oxygen output flow rate is clear at a glance.

[0004] The technical solution adopted in this utility model is as follows: a nasal oxygen tube with oxygen output detection function, including a nasal plug, an oxygen hose and an oxygen inlet connector. The connecting end of the nasal plug is fixed to the outlet end of the oxygen hose, and the inlet end of the oxygen hose is connected to the outlet end of the oxygen inlet connector through a float-type oxygen output detection device for oxygen output detection. The float-type oxygen output detection device detects the oxygen output status of the oxygen flowing into the oxygen hose.

[0005] The float-type oxygen detection device includes a transparent spherical tube and a float located inside the spherical tube. The air inlet end of the oxygen hose is connected to one end of the spherical tube, and the other end of the spherical tube is connected to the air outlet end of the oxygen inlet connector. When oxygen in the oxygen inlet connector enters the oxygen hose through the spherical tube, it is indicated by the float floating and shifting inside the spherical tube.

[0006] Furthermore, the inner diameter of the sphere tube is larger than the outer diameter of the float.

[0007] Furthermore, the outer diameter of the float is larger than the inner diameter of the oxygen hose, and the outer diameter of the float is larger than the orifice of the outlet end of the oxygen inlet connector.

[0008] Furthermore, the oxygen hose inlet end is cut at a 45° angle and inserted into the tube hole at one end of the sphere tube.

[0009] Furthermore, the float is a small red, green, or blue plastic ball.

[0010] Advantages of this utility model compared to the prior art:

[0011] 1. This technical solution solves the problem that traditional portable oxygen supply devices cannot determine the oxygen delivery status at low flow rates by installing a float-type oxygen supply detection device between the oxygen hose and the oxygen inlet connector. This provides detection conditions for extending the oxygen supply time by using low flow rate oxygen supply, which helps to reduce the oxygen waste caused by high flow rate oxygen supply and achieve the goal of saving oxygen.

[0012] 2. This technical solution utilizes the extremely light weight of the float. The float is installed inside the sphere tube. When the oxygen in the oxygen inlet connector flows through the sphere tube to the oxygen hose, the float can roll freely inside the sphere tube when it encounters a very small flow of oxygen, informing the oxygen user that oxygen has flowed out, thereby achieving the purpose of saving oxygen.

[0013] 3. This technical solution has a simple structure, novel and reasonable design, convenient and quick disassembly and assembly, low cost, high detection sensitivity, and the oxygen output status and oxygen flow rate are clear at a glance, making it highly valuable for use. Attached Figure Description

[0014] Figure 1 This is a schematic diagram of the structure of this utility model. Detailed Implementation

[0015] The following will refer to the embodiments of this utility model. Figure 1 The technical solutions in the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0016] It should be noted that, unless otherwise stated herein, the terms "center," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, are used only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the invention. Furthermore, the terms "first," "second," and "third," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0017] In this document, the terms "comprising," "including," or any other variations thereof are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.

[0018] Nasal oxygen cannulas with oxygen output detection function, such as Figure 1 As shown, the device includes a nasal plug 1, an oxygen hose 2, and an oxygen inlet connector 5. The connecting end of the nasal plug 1 is fixed to the outlet end of the oxygen hose 2, and the inlet end of the oxygen hose 2 is connected to the outlet end of the oxygen inlet connector 5 through a float-type oxygen outlet detection device for detecting oxygen output. The float-type oxygen outlet detection device detects the oxygen output status of the oxygen flowing into the oxygen hose 2, including whether there is an oxygen flow and the magnitude of the oxygen flow. In the above structure, by setting a float-type oxygen outlet detection device between the oxygen hose 2 and the oxygen inlet connector 5, the device detects the oxygen output status of the oxygen flowing into the oxygen hose 2, solving the problem that traditional portable oxygen supply devices cannot determine the low-flow oxygen delivery status. This provides detection conditions for extending the oxygen supply time with low-flow oxygen output, which helps to reduce the oxygen waste caused by high-flow oxygen output and achieves the purpose of saving oxygen.

[0019] The specific structure of the float-type oxygen output detection device is as follows: The float-type oxygen output detection device includes a transparent ball chamber tube 3 and a float 4 located inside the ball chamber tube 3. The air inlet end of the oxygen hose 2 is connected to one end of the ball chamber tube 3, and the other end of the ball chamber tube 3 is connected to the air outlet end of the oxygen inlet connector 5. When the oxygen in the oxygen inlet connector 5 enters the oxygen hose 2 through the ball chamber tube 3, it is indicated by the float 4 floating and shifting inside the ball chamber tube 3.

[0020] The inner diameter of the sphere tube 3 is larger than the outer diameter of the float 4 to ensure that the float 4 can move freely inside the sphere tube 3 when it encounters an oxygen flow. At the same time, in order to limit the position of the float 4, it is necessary to ensure that the outer diameter of the float 4 is larger than the inner diameter of the oxygen hose 2, and that the outer diameter of the float 4 is larger than the orifice of the outlet end of the oxygen inlet connector 5, so that the float 4 can only move back and forth inside the sphere tube 3.

[0021] In order to achieve quick connection between oxygen hose 2 and sphere tube 3, the inlet end of oxygen hose 2 is cut into a 45° bevel and then inserted into the tube hole at one end of sphere tube 3.

[0022] Taking advantage of the extremely light weight of the float 4, the float 4 is installed inside the sphere tube 3. When the oxygen in the oxygen inlet connector flows through the sphere tube to the oxygen hose, the float 4 can roll freely inside the sphere tube 3 when it encounters a very small flow of oxygen, thus informing the oxygen user that oxygen has flowed out, thereby achieving the purpose of saving oxygen.

[0023] The float 4 is an easily identifiable colored plastic ball, that is, the float 4 can be an easily identifiable color such as red, green, or blue.

[0024] This technical solution has a simple structure, novel and reasonable design, convenient and quick disassembly and assembly, low cost, and high detection sensitivity. It can detect low-flow oxygen at 0.1L / min, and the oxygen output status and flow rate are clearly visible, making it highly valuable for practical use.

[0025] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0026] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
