Description

Technical Field

[0001] The present application relates to the field of atomization devices, and in particular to a double-chamber atomization device. Background Art

[0002] Nebulizer therapy is a conventional treatment for respiratory diseases. Patients use a mask and a mouthpiece to connect the nebulizer and then inhale it through the nose or mouth. During the nebulizer treatment, the drug mist overflows with the patient's exhalation, causing waste; the drug mist and air spray together to form large particles that are inhaled into the body, making it difficult for the drug to be effective, and the treatment efficiency is low. Inhalation and exhalation pass through the same channel, causing drug mist contamination.

[0003] At present, in the market, a mist storage chamber is added between the nebulizer and the mouthpiece to cache the medicine mist, which can reduce waste and have a certain buffering effect. Its structure is mainly a section of empty tube, but the empty tube is directly connected to the inhalation and exhalation channel, and the inhalation and exhalation still pass through the same channel, which has the following disadvantages.

[0004] Inhalation and exhalation pass through the same channel, which will cause the drug mist to mix with the exhaled gas and enter the body, causing drug mist contamination.

[0005] The single channel for inhalation and exhalation will cause the drug mist to escape and be wasted during exhalation, reducing the utilization rate of the drug mist, making it difficult to exert the drug effect and resulting in low treatment efficiency.

[0006] Although the existing technology of adding empty pipes to store medicine mist has achieved buffering, its effect is poor. At the same time, the medicine mist cannot be screened, resulting in relatively low absorption efficiency. Utility Model Content

[0007] The purpose of the present application is to provide a dual-chamber atomization device, which separates the air flow channels for the patient's inhalation and exhalation to prevent drug mist contamination; the inner cavity of the mist storage chamber is not directly connected to the mouthpiece channel, and the buffering effect is better. The drug mist needs to pass through a circular air flow channel; large particles of drug mist can be screened out, and small particles enter the patient's body for faster absorption, thereby improving the treatment effect.

[0008] In order to solve the above technical problems, the following technical solutions are adopted:

[0009] In a first aspect, the present application provides a dual-chamber atomization device, comprising an atomization medicine cup, a fog storage chamber and a mouthpiece, characterized in that the fog storage chamber comprises a fog storage outer shell, a fog storage inner tank and a bottom cover, a back one-way valve is provided on the side wall of the fog storage outer shell, a bottom one-way valve is provided on the bottom cover, and at least one fog outlet is provided on the side wall of the fog storage inner tank.

[0010] When the gas passes through the back one-way valve, it can only flow out from the mist storage shell; when the gas passes through the bottom one-way valve, it can only enter the mist storage inner container from the outside.

[0011] The mist storage inner container is arranged inside the mist storage outer shell, and a gap between an inner wall of the mist storage outer shell and an outer wall of the mist storage inner container forms an air flow channel.

[0012] Optionally, the nebulizer medicine cup includes a medicine cup shell and a nebulizer set, and the nebulizer set includes a nebulizer sheet, a waterproof silicone ring and an electrode probe; the nebulizer sheet is arranged in the medicine cup shell, and the waterproof silicone ring is provided on the outer periphery of the nebulizer sheet, the nebulizer sheet is connected to the electrode probe wire, and the nebulizer sheet is powered on to perform nebulization after being connected to the power supply through the motor probe.

[0013] Optionally, the medicine cup shell includes a cup cover, an upper shell and a lower shell, one end of the lower shell cooperates with the waterproof silicone ring of the upper shell to clamp the atomization kit and is fixed with screws, the internal space formed by the cup cover, the lower shell and the cavity inside the upper shell is a medicine liquid tank, and the other end of the lower shell is provided with a mist outlet nozzle.

[0014] Optionally, one end of the mist storage inner tank is connected to the bottom cover, and the other end is provided with a nozzle interface, and the nozzle interface and the mist outlet nozzle are assembled and fixed by interference fit.

[0015] Optionally, after the mist storage shell and the mist storage liner are installed on the bottom cover, the mist outlet is at the same height as the back one-way valve on the mist storage shell.

[0016] Optionally, a medicine cup mounting platform is provided at one end of the mist storage housing, and the other end cooperates with the bottom cover, and the medicine cup mounting platform cooperates with the atomization medicine cup.

[0017] Optionally, a mouthpiece joint is further provided on the side wall of the mist storage shell, and the mouthpiece is provided on the mouthpiece joint.

[0018] Optionally, the one-way valve includes a one-way diaphragm and a diaphragm mounting structure, and the one-way diaphragm is mounted on the diaphragm mounting structure.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 1. This application uses the back one-way valve on the side wall of the mist storage shell, the bottom one-way valve on the bottom cover, and the mist outlet on the mist storage liner to allow the patient's exhaled gas to enter the airflow channel and then be discharged through the back one-way valve. The gas entering through the bottom one-way valve on the bottom cover at the bottom of the mist storage shell, with the gas atomized from the medicine cup, enters the airflow channel through the mist outlet of the mist storage liner and then enters the patient's airway for treatment. When inhaling, the gas passes through a longer path to reach the mouthpiece and enter the patient's body. When exhaling, the gas passes through a shorter path and is easier to be discharged. When inhaling, when the gas reaches the airflow channel, the exhaled gas has been discharged, so the medicine mist will not mix with the exhaled gas and enter the patient's body, avoiding the contamination of the medicine mist and the exhaled gas.

[0021] 2. The air flow channel formed by the gap between the mist storage shell and the mist storage inner tank provided in the present application is an annular channel. When the gas passing through the drug atomization can screen out large particles of drug mist, smaller particles of drug enter the patient's body from the mouthpiece, accelerate the effect of the drug in the body, and efficiently exert the drug effect.

[0022] 3. The medicine in the medicine cup provided in the present application is atomized into medicine mist by the atomization kit and then stored in the inner cavity of the mist storage tank. When the patient inhales, it enters the air flow channel together with the air entering through the bottom one-way valve. The airflow of the medicine mist stored in the mist storage tank is more peaceful, avoiding relative collision with the incoming air to form large particles of medicine mist. The medicine mist stored in the mist storage tank plays a buffering role, thereby improving the utilization rate of the medicine. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means intended to limit the present application and its application or use. Example

[0036] like Figure 1-3 As shown, this embodiment provides a dual-chamber nebulizer device, including a nebulizer cup 1, a mist storage chamber 2 and a mouthpiece 3, the nebulizer cup 1 is arranged above the mist storage chamber 2, the mouthpiece 3 is arranged on the side wall of the mist storage chamber 2, and the mouthpiece 3 is in contact with the patient's oral cavity.

[0037] The mist storage bin 2 includes a mist storage shell 201, a mist storage liner 202 and a bottom cover 203. The mist storage liner 202 is arranged in the mist storage shell 201, and the bottoms of the mist storage shell 201 and the mist storage liner 202 are fixed on the bottom cover 203. The storage liner 202 is used to store the medicine mist generated by the atomization medicine cup 1. A back check valve is arranged on the side wall of the atomization shell 201, and the back check valve opens when the patient exhales to discharge the exhaled gas. A bottom check valve is arranged on the bottom cover 203, and the bottom check valve opens when the patient inhales, and the air and the medicine mist stored in the mist outlet liner enter the patient's body.

[0038] A nozzle interface 210 is provided on the top of the mist storage inner tank 202, and a mist outlet 212 is provided on the side wall of the mist storage inner tank 202. At least one mist outlet 212 is provided, and the medicine mist stored in the mist storage inner tank 202 passes through the mist outlet 212. When the user inhales, the bottom one-way valve opens to allow air to enter. The incoming air and the medicine mist stored in the mist storage inner tank 202 enter the air flow channel between the mist storage inner tank 202 and the mist storage outer shell 201 from the mist outlet 212, and then enter the patient's body through the mouthpiece 3. Example

[0039] The present embodiment provides a technical solution based on the embodiment 1, which is different from the embodiment 1 in that the atomizing medicine cup 1 described in the embodiment 1 comprises an atomizing sheet 101, a waterproof silicone ring 102, an electrode probe 103, a cup cover 104, an upper shell 105 and a lower shell 106; the atomizing sheet 101 is arranged in the lower shell 106, a waterproof silicone ring 102 is arranged on the outer periphery of the atomizing sheet 101, the atomizing sheet 101 is connected to the electrode probe 103 by wires, the atomizing sheet 101 is powered on to perform atomization after being connected to a power source through the motor probe 103, the lower shell 106 is fixed to the upper shell 105 with screws, and the enclosed space formed by the cup cover 104, the lower shell 106 and the V-shaped cavity inside the upper shell is a medicine liquid tank 107, the medicine liquid tank 107 is used to store medicines, and the stored medicines are atomized and used through the atomizing sheet 101 on the lower shell 106.

[0040] like Figure 4 and Figure 5 As shown, the cup cover 104 is arranged above the upper shell 105, the atomizing sheet 101 and the waterproof silicone ring 102 are arranged in the lower shell 106, and the electrode probe 103 is led out from the lower shell 106. When the electrode probe is energized, the atomizing sheet begins to atomize the medicine in the medicine liquid tank, and the atomized medicine mist is sprayed out through the mist outlet nozzle 108 provided at the lower end of the lower shell 106.

[0041] like Figure 6-8 As shown, a mouthpiece joint 206 and a back one-way valve are provided on the side wall of the mist storage housing 201 for discharging the gas exhaled by the user, a medicine cup mounting platform 204 is provided above the mist storage housing 201, a bottom one-way valve is provided in the bottom cover 203, and both the back one-way valve and the bottom one-way valve are composed of a one-way diaphragm 208 and a diaphragm mounting structure 209, and the one-way diaphragm 208 is arranged on the diaphragm mounting structure 209.

[0042] The gas can only flow out of the mist storage shell 201 through the back one-way valve, and the external gas cannot flow into the internal space of the mist storage shell 201 from the back one-way valve; the gas can only enter the mist storage liner 202 from the bottom through the bottom one-way valve, and the gas in the mist storage liner 202 cannot flow out from the bottom one-way valve.

[0043] like Fig. 9 and Fig.10 As shown, during use, when the patient exhales, the exhaled gas enters from the mouthpiece interface 210, passes through the airflow channel formed by the inner wall of the mist storage shell 201 and the outer wall of the mist storage liner 202, and is discharged from the back one-way valve on the side wall of the mist storage shell 201. The gas passing through the back one-way valve can only flow out from the mist storage shell 201, and external gas cannot flow into the internal space of the mist storage shell from the one-way valve.

[0044] When the patient inhales, the air pressure in the mist storage shell 201 is greater than the external air pressure, and the external air enters the mist storage liner 202 from the bottom one-way valve of the bottom cover 203. The air entering the mist storage liner 202 carries the medicine mist that has been discharged and stored in the inner cavity of the mist storage liner 202 and enters the air flow channel from the mist outlet 212, and enters the mouthpiece joint 206 through the air flow channel and enters the patient's body. The gas can only enter the mist storage liner 202 from the bottom through the bottom one-way valve, and the gas in the mist storage liner 202 cannot flow out from the bottom one-way valve, which limits the bottom one-way valve to be used only during inhalation.

[0045] During inhalation, the gas passes through a longer path to reach the mouthpiece and enter the patient's body. During exhalation, the gas passes through a shorter path and is easier to be discharged. Therefore, during inhalation, the air entering through the bottom one-way valve enters the mist storage liner 202 and mixes with the medicine mist before entering the air flow channel 4 from the mist outlet 212. The gas exhaled last time has already passed through the air flow channel and discharged from the back one-way valve. The medicine mist will not mix with the exhaled gas to cause medicine mist contamination.

[0046] The mist storage shell 201 and the mist storage liner 202 are cylindrical, and the airflow channel 4 formed therebetween is an annular channel. When the granular medicine mist passes through the annular airflow channel 4, the larger granular medicine mist can fall to the bottom of the channel. The patient inhales the smaller granular medicine mist, which is absorbed by the body faster and has a therapeutic effect faster.

[0047] The mist outlet nozzle 108 is located in the cavity of the mist storage tank 202, and the atomized medicine is stored in the cavity of the mist storage tank. When the patient inhales, the air entering through the bottom one-way valve carries the medicine mist in the mist storage tank into the air flow channel 4 from the mist outlet 212. The airflow of the medicine mist stored in the cavity of the mist storage tank 202 is smooth, avoiding collision with the incoming air to form large particles, thereby improving the utilization rate of the medicine.

[0048] The above is only a preferred implementation of the present application. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present application. These improvements and modifications should also be regarded as the scope of protection of the present application.
