Description

Technical Field

[0001] This invention relates to the field of medical device technology, and in particular to a nasal inhalation therapy device. Background Technology

[0002] Sinusitis is an infection of the lining of the sinuses, which can be acute or chronic. When the sinuses become blocked and filled with fluid, bacteria can thrive, causing symptoms such as headaches and yellow nasal discharge. Sinus blockage can be caused by the common cold, pollen allergies, or nasal polyps (small bumps inside the nose).

[0003] In addition to conventional treatments, with the development of medicine, nasal inhalers have appeared on the market. Their core principle is to use independent sound waves and generate positive airway pressure (PEP) to help open the airway, improve and clear secretions, and have a good effect on the treatment of sinusitis.

[0004] Therefore, the core components of current therapeutic devices include the excitation valve and the sound wave generating component. The excitation valve currently uses a ball valve. Its principle is that when a person exhales, the positive pressure in the cavity pushes the ball valve up, opening the air passage. When inhaling, because the cavity is under negative pressure, the ball valve uses its own weight to block the air passage to ensure the pressure in the cavity is stable. However, the above structure has the following drawbacks: First, the specifications of the excitation valve are different in each therapeutic device, especially the weight of the ball valve. For example, the ball valve of the therapeutic device for adults is much heavier than that of the ball valve for children, so they cannot be used interchangeably. In addition, because the ball valve vibrates up and down and hits the bracket, it not only generates a lot of noise, but also causes wear and tear after long-term use, especially affecting the airtightness during inhalation and causing unstable negative pressure in the cavity.

[0005] Therefore, it is necessary to improve the existing excitation valve structure to overcome the above-mentioned defects. Summary of the Invention

[0006] The primary objective of this invention is to provide a nasal inhalation therapy device that addresses the shortcomings of requiring different models for different populations, as well as issues such as high noise levels and easy wear and tear.

[0007] This invention provides a nasal inhalation therapy device, comprising a device body with a sealed cavity, a first opening and a second opening on the device body communicating with the sealed cavity, and an air inlet. A mask adapted to the human nose is provided at the first opening, and a vibration valve is provided at the second opening. An acoustic vibration component providing acoustic vibration is provided within the sealed cavity. The second opening has a circular cross-section. The vibration valve includes a vortex impeller assembly rotatably disposed within the second opening. The vortex impeller assembly includes a wheel axle rotatably connected relative to the housing, a wheel axle sleeve fixed to one end of the wheel axle, and vortex blades fixedly disposed on the outer periphery of the wheel axle sleeve and adapted to the inner wall of the second opening. A semi-circular movable baffle is fixedly disposed at the top of the wheel axle sleeve. A semi-circular fixed baffle cooperating with the movable baffle is fixedly disposed at the upper part of the second opening. A semi-circular sealing baffle is rotatably connected to the fixed baffle. The sealing baffle is closed when the human body inhales.

[0008] Optionally, a hollow frame is detachably connected to the top of the treatment device body, and the upper end of the wheel axle is rotatably connected to the hollow frame via a bearing.

[0009] Optionally, the lower end of the second opening is provided with a flow channel that communicates with the cavity of the mask.

[0010] Optionally, the flow channel is provided with a spiral flow channel groove or a spiral flow rib.

[0011] Optionally, the sealing baffle includes a substrate made of lightweight material and a sealant layer wrapped around the surface of the substrate. The two ends of the substrate are respectively hinged to the two ends of the fixed baffle, and a reset spring is provided at the hinge.

[0012] Optionally, the substrate is made of plastic, and the sealant layer is sealant silicone.

[0013] Optionally, the fixed baffle, the movable baffle, and the sealing baffle are all provided with through holes for the wheel axle to pass through.

[0014] Optionally, the mask is made of medical-grade silicone and is detachably connected to the main body of the treatment device.

[0015] Optionally, the acoustic vibration assembly includes an acoustic vibrator, a circuit board electrically connected to the acoustic vibrator, and a power supply for supplying power to the acoustic vibrator and the circuit board.

[0016] Optionally, the power source includes a battery pack and a charging port disposed on the housing, wherein the battery pack is electrically connected to the charging port.

[0017] The technical solution of this invention replaces the circular ball valve with the excitation valve of the swirl impeller assembly. As a result, the excitation frequency will adaptively adjust according to the different exhalation pressures of different users, thus matching the needs of different users. In addition, since there is no need to use a ball valve to create mechanical vibration through up-and-down impact, the noise is low and it is not easy to wear, thus extending the service life.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the stated features.

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0024] like Figures 1-5 As shown, a nasal inhalation therapy device includes a therapy body 1 with a sealed cavity, a first opening 2 and a second opening 3 on the therapy body 1 communicating with the sealed cavity, and an air inlet 4. A mask 5 adapted to fit the human nose is provided at the first opening 2. A vibration valve is provided at the second opening 3. An acoustic vibration component 12 providing acoustic vibration is provided inside the sealed cavity. The cross-section of the second opening 3 is circular. The vibration valve includes a vortex impeller assembly rotatably disposed within the second opening 3. The impeller assembly includes a wheel shaft 6 rotatably connected to the housing, a wheel shaft 6 sleeve fixed to one end of the wheel shaft 6, and swirl blades 7 fixedly disposed on the outer periphery of the wheel shaft 6 sleeve and adapted to the inner wall of the second opening 3. A semi-circular movable baffle 8 is fixedly disposed on the top of the wheel shaft 6 sleeve, and a semi-circular fixed baffle 9 that cooperates with the movable baffle 8 is fixedly disposed on the upper part of the second opening 3. A semi-circular sealing baffle 10 is rotatably connected to the fixed baffle 9. The sealing baffle 10 is in a closed state when a person is inhaling.

[0025] The working principle of this invention is as follows: When a person inhales, the sealed cavity of the therapeutic instrument body 1 is under negative pressure. Outside air enters the sealed cavity through the air inlet 4. At this time, the sealing baffle 10 is closed under the pressure of the external atmospheric pressure, and cooperates with the fixed baffle 9 to seal the second opening 3, thereby ensuring the stability of the air pressure in the sealed cavity. When a person exhales, the sealed cavity is under positive pressure. At this time, the positive pressure airflow passes through the swirl vane 7, which drives the swirl vane 7 to rotate around the wheel shaft 6, thereby driving the movable baffle 8 to rotate. When the movable baffle 8 overlaps with the fixed baffle 9, the second opening 3 is opened, the high pressure gas flows out, and the positive pressure in the sealed cavity pushes the rotating movable baffle 8 up and discharges it from the sealed cavity. During the rotation of the swirl vane 7, the movable baffle 8 continuously switches between alternating and overlapping states with the fixed baffle 9. Therefore, the second opening 3 is continuously opened and closed, that is, the movable baffle 8 alternately blocks the second opening 3, and the gas in the sealed cavity instantly accumulates and depressurizes, generating a continuous low-frequency pulsating positive airway pressure. The pressure wave is transmitted to the respiratory tract, loosening the sputum. Moreover, as the expiratory pressure is higher, the rotation speed of the swirl vane 7 is faster, and the duty cycle of the movable baffle 8 blocking the airway is reduced, which is equivalent to the automatic increase of the flow area, the decrease of ventilation resistance, and the increase of vibration frequency. This is equivalent to the smoother ventilation when the pressure is higher when using a ball valve vibration valve. Compared with the traditional ball valve vibration valve, the vibration valve with this structure does not need to match different models according to the user's age. When users of different ages use it, it can automatically adjust the vibration frequency according to the user's own expiratory pressure, without adjusting the weight of the ball valve itself. In addition, the above structure has no noise from hard impacts and will not cause wear.

[0026] In order to maintain the swirl blade 7 assembly, a hollow frame 13 is detachably connected to the top of the treatment device body 1. The upper end of the wheel axle 6 is rotatably connected to the hollow frame 13 through a bearing. Preferably, the wheel axle 6 and the hollow frame 13 are also detachably connected. Therefore, during maintenance, after removing the hollow frame 13, the wheel axle 6 can be separated from the hollow frame 13, and the sputum carried out by the respiratory tract remaining on the surface of the fixed baffle 9, the movable baffle 8, the sealing baffle 10, and the swirl blade 7 can be wiped to prevent bacterial growth.

[0027] To improve the efficiency of the positive pressure airflow in the sealed cavity driving the swirl blade 7 to rotate, a guide channel 11 communicating with the cavity of the mask 5 is provided at the lower end of the second opening 3. The guide channel 11 is provided with a spiral guide groove or a spiral guide rib. After the positive pressure airflow in the sealed cavity changes its airflow direction through the guide channel 11, the positive pressure airflow impacts the tip of the swirl blade 7. If the guide channel 11 is not provided, part of the positive pressure airflow will directly impact the root of the swirl blade 7, and this part of the positive pressure airflow cannot effectively drive the swirl blade 7 to rotate. Therefore, the guide channel 11 can effectively utilize most of the positive pressure airflow.

[0028] In order for the positive pressure airflow to lift the sealing baffle 10 during exhalation, the sealing baffle 10 includes a substrate made of lightweight material and a sealing adhesive layer wrapped around the surface of the substrate. The two ends of the substrate are respectively hinged to the two ends of the fixed baffle 9, and a return spring is provided at the hinge. Preferably, the substrate is made of plastic and the sealing adhesive layer is sealing silicone.

[0029] To avoid motion interference, the fixed baffle 9, the movable baffle 8, and the sealing baffle 10 are all provided with through holes for the wheel axle 6 to pass through.

[0030] Preferably, the mask 5 is made of medical-grade silicone, and the mask 5 is detachably connected to the treatment device body 1, so that the mask 5 can be removed for regular cleaning and disinfection.

[0031] The acoustic vibration assembly 12 includes an acoustic vibrator, a circuit board electrically connected to the acoustic vibrator, and a power supply for powering the acoustic vibrator and the circuit board. Additionally, the treatment device body 1 is equipped with a control button. When the control button is activated, the power supply powers the acoustic vibrator, which emits sound waves that travel through the air into the human respiratory tract. Sound vibrations such as humming have been shown to significantly increase the nitric oxide content in the nasal cavity. Nitric oxide is a tasteless gas molecule formed in the body during nasal breathing. Its functions include dilating blood vessels, increasing oxygen levels, regulating blood pressure, and preventing bacteria, viruses, fungi, and other invaders from entering the nasal respiratory tract. Furthermore, it has been shown that optimal nitric oxide release is achieved at a frequency of 128 Hz. In addition, the sound vibration promotes the dispersion and fragmentation of mucus secretions, making it easier to clear sinus and nasal mucus.

[0032] Regarding the power supply, existing dry cell batteries, rechargeable dry cell batteries, or charging plugs can be used. However, when using dry cell batteries, their weight is relatively heavy, and since the device is handheld, it is not very convenient to use and is prone to shaking and abnormal noise. When using a charging plug, the length of the charging cable limits the operating distance of the device. Therefore, this embodiment adopts the following preferred solution, in which the power supply includes a battery pack and a charging port disposed on the treatment device body 1. The battery pack is electrically connected to the charging port. When the battery pack's power is insufficient, it can be charged through the charging port, enhancing the nasal inhalation device's battery life, avoiding the need to replace batteries, reducing the operator's workload, and the battery pack's weight is also less than that of the batteries, making it easier for the operator to hold.

[0033] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention 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; and these 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 the present invention.
