Description

Technical Field

[0001] This utility model relates to the technical field of nitric oxide therapy devices, specifically to a nitric oxide hair growth device for treatment and a nitric oxide therapy device thereof. Background Technology

[0002] Inhaled nitric oxide (NO) is a novel respiratory emergency treatment technology used in clinical practice, gaining attention due to its advantages such as rapid efficacy, non-invasiveness, and high selectivity. The generation mechanisms of NO can be broadly categorized into three types: spark plug discharge generation, chemical reaction generation, and the use of medical NO cylinders. Among these, the spark plug discharge generation method is relatively simple in principle, low in cost, and does not require regular medication replacement; therefore, many manufacturers both domestically and internationally have already developed or are developing NO treatment devices based on this method.

[0003] The nitric oxide (NO) therapy device includes a nitric oxide (NO) hair regrowth unit. The internal structure of the NO hair regrowth unit is a chamber structure containing a spark plug. The spark plug includes a central electrode and side electrodes. The central electrode (positive electrode of the spark plug) is made of a precious metal or its alloy, while the side electrodes (negative electrodes) are generally made of the same material as the positive electrode. The side electrodes are welded to a nickel rod substrate. When the NO hair regrowth unit is working, a high-voltage discharge occurs between the central and side electrodes. The air flowing through is ionized into NO and other byproduct gases. These byproduct gases are then filtered out by a downstream filter before being delivered to the patient.

[0004] The positive electrode material of the center electrode (spark plug positive electrode) is generally a precious metal, such as iridium, platinum, or platinum-rhenium alloy, while the side electrode (negative electrode) material is generally a precious metal material welded onto a nickel rod substrate. During high-voltage discharge, as the negative electrode material is continuously consumed, the distance between the positive and negative electrodes continuously widens. Simultaneously, because the nickel rod of the negative electrode has a hooked structure, the metal particles generated by ionization randomly collide on the hooked structure. Occasionally, the center electrode will discharge with the nickel rod, and the discharge position between the positive and negative electrodes changes in real time. This disturbs the airflow, affecting its stability and leading to fluctuations in flow rate and the concentration of NO gas generated by ionization. Ultimately, this affects the stability of the NO concentration inhaled by the patient, impacting the treatment effect.

[0005] In view of this, how to solve the problems of airflow instability and fluctuation of nitric oxide (NO) gas concentration affecting the treatment effect in traditional nitric oxide therapy devices has become the research topic to be solved by this utility model. Utility Model Content

[0006] The purpose of this invention is to provide a nitric oxide hair growth device for therapeutic use and a nitric oxide therapy device.

[0007] To achieve the above objectives, the first aspect of this utility model proposes a therapeutic nitric oxide hair growth device, comprising a shell, wherein the shell has a chamber, and the shell is provided with an air inlet and an air outlet communicating with the chamber. Its innovation lies in:

[0008] The nitric oxide hair growth device includes two spark plugs that pass through the housing and place the center electrode in the chamber. The center electrodes of the two spark plugs are opposite to each other and spaced apart. The center electrode of one spark plug is connected to an external high voltage positive current to form a positive electrode, and the center electrode of the other spark plug is connected to an external high voltage negative current to form a negative electrode.

[0009] To achieve the above objectives, a second aspect of this utility model provides a nitric oxide therapy device, wherein the nitric oxide therapy device uses the nitric oxide hair growth device as described in the first aspect of this utility model.

[0010] The relevant contents of this utility model are explained as follows:

[0011] 1. In the above-mentioned technical solution of this utility model, addressing the problems of airflow instability and fluctuations in nitric oxide (NO) gas concentration affecting the treatment effect in traditional nitric oxide therapy devices, an innovative nitric oxide hair growth device for treatment and a nitric oxide therapy device using the nitric oxide hair growth device are designed. In this nitric oxide hair growth device, compared to the random collisions of metal particles that alter the discharge positions of the center electrode and side electrode of a conventional single spark plug, the center electrodes of two spark plugs are arranged opposite each other and spaced apart, with one of the spark plugs' center electrodes connected to an external high-voltage positive current to form a... The positive electrode and the center electrode of the other spark plug are connected to an external high-voltage negative electrode to form a negative electrode. A strong discharge effect is generated between the center electrodes of the two spark plugs. There is no other metal material between the two center electrodes. During high-voltage discharge, even if the generated metal particles collide with either center electrode, according to the principle of shortest distance discharge, the discharge position of the positive and negative electrodes will still only be the tips of the two center electrodes. The generated discharge arc is relatively stable, which greatly reduces the disturbance to the airflow and improves the flow stability of nitric oxide (NO) gas. Ultimately, it can increase the concentration of nitric oxide (NO) gas inhaled by the patient, thereby improving the treatment effect.

[0012] 2. In the above technical solution, an airflow path is formed inside the housing, through which upstream airflow flows into the chamber via the air inlet and then flows downstream via the air outlet. The center electrodes of the two spark plugs are located in the middle of the airflow path, so that the airflow flows stably through the area where the center electrodes of the two spark plugs are located, making the nitrogen monoxide (NO) airflow generated by the spark plug discharge more stable.

[0013] 3. In the above technical solution, the two spark plugs are symmetrically arranged on both sides of the housing at the middle position, perpendicular to the airflow path, and the discharge gap formed between the center electrodes of the two spark plugs is located at the exact center of the airflow path. This further improves airflow stability.

[0014] 4. In the above technical solution, the center electrode of the spark plug of the positive electrode is connected to an external high voltage positive current, and the center electrode of the spark plug is tightly wrapped by an insulating ceramic body, so as to have good insulation from the external metal.

[0015] The center electrode of the negative spark plug is connected to an external high-voltage negative power source. The center electrode of the spark plug is grounded to the metal part of the housing through a wire, thereby avoiding the accumulation of static electricity in the metal housing and avoiding the risk of electric shock.

[0016] 5. In the above technical solution, the housing includes an outer shell and an inner shell, the inner shell is fitted inside the outer shell, and through holes are provided on both sides of the inner shell for the spark plug to pass through. The interior of the inner shell forms the chamber, thereby making the formation of the chamber and the arrangement of the spark plug more reasonable.

[0017] 6. In the above technical solution, the outer shell is a metal structure, specifically an aluminum alloy shell, which has high structural strength and can be used for grounding; the inner shell is a polymer structure, specifically PTFE material, which is resistant to high temperature and oxidation and will not react with ionization products; threaded holes for the spark plug to be screwed on both sides of the outer shell corresponding to the through hole.

[0018] 7. In the above technical solution, the outer shell is provided with a groove on the outer surface of the threaded hole, and a brass gasket for conducting the spark plug metal shell and the outer shell is installed in the groove. The brass gasket mainly serves to conduct the spark plug metal shell and the nitric oxide generator shell, and prevents discharge between the positive electrode of the spark plug and the aluminum alloy shell.

[0019] 8. In the above technical solution, the outer shell has a square structure, which facilitates the overall assembly of the nitric oxide hair growth device in the treatment device. The inner shell and the inner shell have a circular structure. The cylindrical chamber / airflow channel formed by the circular inner shell makes the airflow more stable and improves the flow stability of the generated nitric oxide. After the inner shell is assembled into the outer shell, it is fixedly connected by the end cap, which facilitates the loading and unloading of the inner shell.

[0020] 9. In the above technical solution, a sealing ring is provided between the outer shell and the end cover to play a sealing role and prevent the chamber from entering through the leakage point due to poor sealing and interfering with the airflow.

[0021] 10. In this utility model, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection, a direct connection, or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0022] 11. In this utility model, the terms “center”, “upper”, “lower”, “axial”, “bottom”, “inner”, “outer”, etc., indicate the orientation or positional relationship based on the orientation or positional assembly relationship shown in the drawings. They are only for the convenience of describing this application 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.

Therefore, it innovatively designs a therapeutic nitric oxide hair growth device and a nitric oxide therapy device using this device. In this nitric oxide hair growth device, compared to the random collisions of metal particles that alter the discharge positions of the center and side electrodes of a conventional single spark plug, the center electrodes of two spark plugs are positioned opposite each other and spaced apart. One of the spark plugs' center electrodes is connected to an external high-voltage positive current to form a positive voltage.

[0044] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0045] This invention aims to solve the problems of airflow instability and fluctuating nitric oxide (NO) gas concentration in traditional nitric oxide therapy devices, which affect the treatment effect. It innovatively designs a therapeutic nitric oxide hair growth device and a nitric oxide therapy device using the therapeutic nitric oxide hair growth device to improve the flow stability of nitric oxide (NO) gas provided by the nitric oxide therapy device.

[0046] Example 1, as Figures 1 to 3 As shown in the figure, Embodiment 1 of this utility model discloses a nitric oxide hair growth device for treatment, including a housing 1, the housing 1 having a chamber 10, and an air inlet 101 and an air outlet 102 communicating with the chamber 10. The nitric oxide hair growth device includes two spark plugs 2 that pass through the housing 1 and place the central electrode 21 in the chamber 10. The central electrodes 21 of the two spark plugs 2 are opposite to each other and spaced apart. The central electrode 21 of one spark plug 2 is connected to an external high voltage positive current to form a positive electrode 210, and the central electrode 21 of the other spark plug 2 is connected to an external high voltage negative current to form a negative electrode 220.

[0047] Through the implementation of Embodiment 1 of this utility model, in this nitric oxide generator, compared to the conventional single spark plug 2 where the discharge position of the center electrode 21 and side electrode changes due to random collisions of metal particles, the two spark plugs 2 have their center electrodes 21 facing each other and spaced apart. One of the spark plugs 2's center electrodes 21 is connected to an external high-voltage positive current to form a positive electrode 210, and the other spark plug 2's center electrode 21 is connected to an external high-voltage negative current to form a negative electrode 220. A strong discharge effect is generated between the two spark plugs 2's center electrodes 21, and there is no other metal material between the two center electrodes 21. During high-voltage discharge, even if the generated metal particles collide with either center electrode 21, according to the principle of shortest distance discharge, the discharge position of the positive and negative electrodes 220 will still only be the tips of the two center electrodes 21. The generated discharge arc is more stable, greatly reducing the disturbance to the flowing air and improving the flow stability of nitric oxide (NO) gas.

[0048] In the above embodiment one of this utility model, as Figure 3 As shown, the housing 1 has an airflow path formed inside, through which the upstream airflow flows into the chamber 10 via the air inlet 101 and then flows downstream via the air outlet 102. The center electrodes 21 of the two spark plugs 2 are located in the middle of the airflow path, so that the airflow flows stably through the area where the center electrodes 21 of the two spark plugs 2 are located, making the nitrogen monoxide (NO) airflow generated by the spark plugs 2 discharge more stable.

[0049] More specifically, the two spark plugs 2 are symmetrically arranged on both sides of the housing 1 at the middle position, perpendicular to the airflow path, and the discharge gap formed between the center electrodes 21 of the two spark plugs 2 is located at the exact center of the airflow path. This further improves airflow stability.

[0050] In the above embodiment one of this utility model, as Figure 2 As shown, the spark plug 2 of the positive electrode 210 has its center electrode 21 connected to an external high-voltage positive power source. The center electrode 21 of the spark plug 2 is tightly wrapped by an insulating ceramic body, thus providing good insulation against the external metal. The spark plug 2 of the negative electrode 220 has its center electrode 21 connected to an external high-voltage negative power source. The center electrode 21 of the spark plug 2 is connected to the metal part of the housing 1 through a wire to ground, thereby avoiding the accumulation of static electricity in the metal shell and avoiding the risk of electric shock.

[0051] In the above embodiment one of this utility model, as Figure 2 , Figure 3 As shown, the housing 1 includes an outer shell 11 and an inner shell 12. The inner shell 12 is fitted inside the outer shell 11. The inner shell 12 has through holes on both sides for the spark plug 2 to pass through. The interior of the inner shell 12 forms the chamber 10, thereby making the formation of the chamber 10 and the arrangement of the spark plug 2 more reasonable.

[0052] Furthermore, the outer shell 11 is a metal structure, specifically an aluminum alloy shell 11, which has high structural strength and can be used for grounding; the inner shell 12 is a polymer structure, specifically PTFE material, which is resistant to high temperature and oxidation and will not react with ionization products. Threaded holes for the spark plug 2 to be screwed on both sides of the outer shell 11 corresponding to the through hole are provided.

[0053] Specifically, the outer casing 11 has a groove 111 on the outer surface of the threaded hole. A brass gasket 3 for conducting the spark plug 2 metal shell and the outer casing 11 is installed in the groove 111. The brass gasket 3 mainly serves to conduct the spark plug 2 metal shell 11 and the nitric oxide generator shell 11, preventing discharge between the spark plug 2 positive electrode 210 and the aluminum alloy shell 11.

[0054] Furthermore, the outer shell 11 has a square structure on the outside, which facilitates the overall assembly of the nitric oxide hair growth device into the treatment instrument. The inner shell 11 and the inner shell 12 have circular structures. The cylindrical airflow channel formed by the circular inner shell 12 makes the airflow more stable and improves the stability of the generated nitric oxide flow. After the inner shell 12 is assembled into the outer shell 11, it is fixedly connected by the end cap 4, which facilitates the installation and removal of the inner shell 12. A sealing ring 5 is provided between the outer shell 11 and the end cap 4 to seal the airflow and prevent leakage from the chamber 10 due to poor sealing, which could interfere with the airflow.

[0055] Example 2: This utility model discloses a nitric oxide therapy device, which uses the nitric oxide hair growth device as described in Example 1 of this utility model.

[0056] The working process of the nitric oxide therapy device in Embodiment 2 of this utility model can be referred to as follows:

[0057] Air is pressurized by an air pump and then enters an air filter for drying and filtration. It then flows into a flow meter and a nitric oxide generator, where it is ionized into a high concentration of nitric oxide (NO) gas and other associated gases. This ionized gas then flows downstream, is filtered, and enters the ventilator's airway, ultimately reaching the patient's airway. The nitric oxide (NO) generator is the most crucial component of the system.

The outer shell 11 is a square structure made of aluminum alloy, and the inner shell 12 is a circular structure made of PTFE material. The cylindrical chamber 10 / airflow channel is formed by the circular inner shell 12. Through holes are provided on both sides of the inner shell 12 for the spark plug 2 to pass through. Threaded holes for the spark plug 2 to be screwed on both sides of the outer shell 11 corresponding to the through holes are provided. A groove 111 is provided on the outer surface of the threaded hole of the outer shell 11. A brass gasket for conducting the spark plug 2 metal shell and the outer shell 11 is installed in the groove 111. After the inner shell 12 is assembled into the outer shell 11, it is fixedly connected by the end cap 4. A sealing ring 5 is provided between the outer shell 11 and the end cap 4.

[0060] In the third embodiment of this utility model, an airflow path is formed inside the housing 1, through which upstream airflow flows into the chamber 10 via the air inlet 101 and then flows downstream via the air outlet 102. Two spark plugs 2 are symmetrically arranged on both sides of the housing 1 perpendicular to the airflow path. The discharge gap formed between the center electrodes 21 of the two spark plugs 2 is located at the center of the airflow path. The center electrode 21 of the spark plug 2 of the positive electrode 210 is connected to an external high-voltage positive power source and is tightly wrapped by an insulating ceramic body. The center electrode 21 of the spark plug 2 of the negative electrode 220 is connected to an external high-voltage negative power source and is grounded by a wire to the metal part of the housing 1.
