Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a portable nitric oxide therapy device. Background Technology

[0002] Nitric oxide, a highly reactive free radical, is an essential chemical substance for the human body and a crucial signaling gas molecule involved in various physiological processes (such as vasodilation, anti-inflammation, and antiviral activity). In vivo, it primarily exerts its biological functions by increasing cyclic guanosine monophosphate (cGMP) levels. Inhaled nitric oxide is a well-established medical treatment for persistent pulmonary hypertension in newborns, acute respiratory distress syndrome, or lung diseases in premature infants. At concentrations of approximately 5-40 ppm, inhaled nitric oxide can act as a selective vasodilator for pulmonary vessels. The U.S. Food and Drug Administration (FDA) first approved nitric oxide in 1999 for the clinical or echocardiographically associated hypoxic respiratory failure in term and late preterm infants with pulmonary hypertension. Since then, nitric oxide therapy has been clinically applied to treat pulmonary hypertension in term and late preterm infants.

[0003] Existing nitric oxide therapy devices are typically large and heavy, making them inconvenient to transport and only suitable for hospital settings, not for outdoor applications. Utility Model Content

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0049] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.

[0050] like Figure 1As shown, the portable nitric oxide therapy device provided in this embodiment includes: a therapy device housing 100, an air inlet passage 200, a reaction chamber 300, a carrier gas passage 400, and an air outlet passage 500; the air inlet passage 200, the reaction chamber 300, the carrier gas passage 400, and the air outlet passage 500 are all disposed within the therapy device housing 100.

[0051] The air intake end of the air intake passage 200 is connected to the external environment, and the air outlet end of the air intake passage 200 is connected to the reaction chamber 300 and the carrier gas passage 400 respectively, so that the air in the air intake passage 200 is divided into two paths, one path enters the reaction chamber 300 and the other path enters the carrier gas passage 400.

[0052] The outlet of the reaction chamber 300 is connected to the carrier gas passage 400 and the outlet passage 500 respectively. When air enters the reaction chamber 300, the reaction chamber 300 generates nitric oxide gas from the air under the action of an electric arc. The product gas coming out of the outlet of the reaction chamber 300 usually has a high concentration of nitric oxide. The air in the carrier gas passage 400 can dilute the concentration of nitric oxide to a concentration suitable for the user to inhale.

[0053] In an optional embodiment, the reaction chamber 300 includes a chamber body and a pair of electrodes; the pair of electrodes are disposed inside the chamber body; the air inside the chamber body generates nitric oxide gas under the action of an electric arc generated between the pair of electrodes; the chamber body has an air inlet and an air outlet; the air inlet is connected to the air inlet passage 200; the air outlet is connected to the carrier gas passage 400 and the air outlet passage 500, respectively.

[0054] The electric arc method for preparing nitric oxide has significant advantages in miniaturization. In this design, the air inlet passage is divided into two paths after 200. One path enables the immediate preparation of nitric oxide via the electric arc method, while the other path enables the dilution and transmission of carrier gas. The integrated design of the air path allows the therapeutic device to produce the required amount of nitric oxide with fewer components, thus achieving miniaturization and portability of the device, making it suitable for home and outdoor applications.

[0055] Additionally, in alternative implementations, such as Figure 2 , Figure 3 and Figure 4 As shown, in order to facilitate the handling of the treatment device housing 100, a handle groove 110 is provided on the treatment device housing 100. The user can insert their fingers into the handle groove 110 to handle the treatment device housing 100. In addition, a shoulder strap 150 is provided on the treatment device housing 100 so that the treatment device can be worn by the user and is suitable for outdoor use.

[0056] The therapeutic device housing 100 is also equipped with a therapeutic device switch 130 and a charging interface 140. Inside the therapeutic device housing 100 is a rechargeable power supply, which is used to power the electrodes. The rechargeable power supply is charged using the interface 140.

[0057] Furthermore, the air outlet 120 on the treatment device housing 100 is connected to the air outlet passage 500, and devices such as masks and nasal tubes can be connected to the air outlet 120.

[0058] The portable nitric oxide therapy device provided in this embodiment features an air inlet passage 200, a reaction chamber 300, a carrier gas passage 400, and an outlet passage 500 within the device housing 100. External ambient air is split into two paths after entering the air inlet passage 200. One path enters the reaction chamber 300, where nitric oxide is prepared using an electric arc method. The other path enters the carrier gas passage 400. Both the nitric oxide gas generated in the reaction chamber 300 and the air in the carrier gas passage 400 are introduced into the outlet passage 500, where the air dilutes the nitric oxide gas. This integrated gas path design allows for the preparation and dilution of the required amount of nitric oxide with fewer components, achieving miniaturization and portability. Suitable for home and outdoor use, this device alleviates the technical problems of large size and inconvenience in carrying existing nitric oxide therapy devices.

[0059] In an optional embodiment, a first gas control component 10 for controlling the intake flow is provided on the pipeline connecting the air inlet and the intake passage 200. The first gas control component 10 can be configured as a solenoid valve, flow control valve, etc., which can freely adjust the flow rate of gas in the intake passage 200.

[0060] In an optional embodiment, a second gas control component 20 for controlling the gas flow rate within the carrier gas passage 400 is provided on the carrier gas passage 400. The second gas control component 20 can be configured as a solenoid valve, flow control valve, etc., which can freely adjust the gas flow rate within the carrier passage.

[0061] Due to the influence of the internal shape of the reaction chamber 300, the structure of electrodes, and the structure of downstream components in the carrier gas passage 400, the flow rate of the gas input through the inlet passage 200 is unstable as it flows into the reaction chamber 300 and the carrier gas passage 400. This leads to an uncontrollable final output nitric oxide concentration. Therefore, a first gas control component 10 and a second gas control component 20 are provided to ensure that the gas resistance of both paths is constant and controllable, thereby making the gas flow rate through both paths controllable and facilitating the control of the output nitric oxide concentration. Furthermore, the first gas control component 10 can stabilize the gas flow rate entering the reaction chamber 300. A stable airflow helps improve the efficiency of nitric oxide preparation in the reaction chamber 300 and also helps control the concentration of nitric oxide produced.

[0062] In an optional embodiment, an air pump 210 is provided on the air intake passage 200. The air pump 210 is used to deliver air into the air intake passage 200 and provide power for the air in the air intake passage 200 to enter the reaction chamber 300 and the carrier gas passage 400. A first filter 220 is provided on the air intake passage 200. The first filter 220 is located on the air intake side of the air pump 210 near the air intake passage 200. The first filter 220 is used to filter moisture and particulate matter in the air.

[0063] In an optional implementation, nitric oxide is more easily oxidized to toxic nitrogen dioxide. Therefore, before being output to the user, a second filter 510 is provided to filter nitrogen dioxide in the product gas to ensure that the user inhales purer nitric oxide gas. The filter can generally be filled with calcium lime to achieve the nitrogen dioxide filtration function.

[0064] In an optional embodiment, a third gas control component 30 is provided on the gas outlet passage 500. The third gas control component 30 is used to control the flow rate of nitric oxide gas discharged from the gas outlet passage 500, that is, to control the amount of nitric oxide inhaled, so that the flow rate and concentration of nitric oxide-containing gas output to the user are stable. The specific structure of the third gas control component 30 can be the same as that of the first gas control component 10 and the second gas control component 20.

[0065] It should be noted that the third gas control component 30 is located downstream of the second filter 510, which generates a certain gas pressure in the second filter 510, thus helping to improve the filtration effect.

[0066] In an optional embodiment, the portable nitric oxide therapy device further includes a detection branch 600; one end of the detection branch 600 is connected to the gas outlet passage 500, and the other end of the detection branch 600 is connected to the external environment; a fourth gas control component 40 is provided on the detection branch 600, and gas in the gas outlet passage 500 enters the detection branch 600. A nitric oxide sensor 610 is provided on the detection branch 600, which is used to detect the concentration of nitric oxide in the detection branch 600. The concentration is accurately detected by the nitric oxide sensor 610. In addition, the setting of the fourth gas control component 40 can limit the amount of gas entering the detection branch 600 to avoid affecting the amount of gas inhaled by the user. Furthermore, the fourth gas control component 40 can ensure the stability of the downstream gas flow, which helps the nitric oxide sensor 610 to detect the concentration more accurately, and can also prevent the nitric oxide sensor 610 from being damaged due to excessive pressure.

[0067] The portable nitric oxide therapy device provided in this embodiment uses the principle of electric arc method to prepare nitric oxide. Through gas path design, the functions are integrated. It can prepare and output the user's required amount of nitric oxide with fewer components, thus realizing the miniaturization and portability of the therapy device. It is suitable for home and outdoor scenarios, can accurately and effectively control the concentration of output nitric oxide, and can output pure nitric oxide-containing gas.

[0068] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
