[0002] Aerosols, as a commonly used form of inhaled medication delivery, are convenient to use and require relatively low inhalation flow rates from patients, receiving widespread clinical praise from medical staff and patients. However, this type of medication requires a certain level of hand-mouth coordination from the patient. Only with good hand-mouth coordination can the medication be correctly inhaled, reach the lesion site, and achieve the desired therapeutic effect. Therefore, educating and training patients on the correct use of aerosol delivery devices for targeted inhalation is a crucial aspect of ensuring the effectiveness of this medication delivery method.

[0003] The common practice in clinical use is for patients to return to the outpatient clinic after receiving the medication, or for hospitalized patients to receive the medication and then have a nurse demonstrate how to use it without actually taking the medication.

[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0021] In the description of this utility model, it should be understood that the terms "center," "length," "width," "height," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," and "side," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or component 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 this utility model. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0022] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. 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 based on the specific circumstances.

[0023] This utility model provides a training device for simulating an aerosol medication administration device, which facilitates physical demonstrations and teaches patients how to use medication.

[0024] The following is combined with Figures 1-3 The technical solution provided by this utility model will be described in more detail.

[0025] like Figures 1-3 As shown, the training device for simulating an aerosol medication dispensing device provided by this utility model includes a housing 1, a nozzle 2, a pressing part 3, and an elastic reset member 4, wherein: see Figure 2 The pressing part 3 is slidably connected to the outer shell 1, and one end of the pressing part 3 extends out of the outer shell 1 for external pressing; the elastic reset member 4 is located inside the outer shell 1, the fixed end of the elastic reset member 4 is fixed to the outer shell 1, and the other telescopic end abuts against the pressing part 3 to provide pressing resistance; the suction nozzle 2 is fixedly connected to the outer shell 1, and the outer shell 1 is provided with an air inlet 9, which communicates with the suction nozzle 2 and forms an airflow channel.

[0026] Among them, the elastic reset member 4 can be a compression spring in the prior art. When the user presses the pressing part 3, the elastic reset member 4 can provide the pressure when pressing, simulating the pressure when pressing the aerosol medication device.

[0027] The air inlet 9 is located on the outer shell 1, and one or more inlets can be provided. When the user inhales through the mouthpiece 2, a negative pressure is generated inside the outer shell 1, and external air enters the outer shell 1 through the air inlet 9 and enters the mouthpiece 2 through the internal airflow channel, simulating the drug inhalation process of an aerosol drug delivery device.

[0028] This embodiment of the training device for simulating an aerosol medication administration device has a mouthpiece 2 with the same shape as the aerosol medication administration device. The pressing resistance is achieved through a built-in elastic reset member 4. The pressing part 3 on the outer shell 1 simulates the resistance when pressing the medication. During medication administration training, the demonstrator holds the mouthpiece 2 in their mouth, and airflow enters the device from the inhalation inlet 9, passes through the airflow channel, and enters the patient's mouth, demonstrating the inhalation process. The demonstrator then presses the pressing part 3 to demonstrate the medication administration process. This training device for simulating an aerosol medication administration device facilitates physical demonstrations, allowing patients to be taught how to use medication in this way.

[0029] As an optional implementation, see Figures 1-3 As shown, the training device for simulating aerosol medication administration also includes a filter 5. One end of the filter 5 is fixedly connected to the outer shell 1, and the nozzle 2 is located at the other end of the filter 5. The inner cavity of the filter 5 is connected to the nozzle 2 and the air inlet 9. A filter cotton 51 is fixed in the inner cavity of the filter 5. The filter cotton 51 is used to filter the air flowing through the airflow channel.

[0030] Filter 5 can be fixed to housing 1 via threaded connection, snap-fit, screws, or other detachable connection methods. Filter 5 is used to block cross-infection sources such as saliva and droplets. It is for single-person use, and a new filter 5 should be replaced before each person operates to avoid cross-infection. The resistance of the filter cotton 51 on filter 5 is within a limited range, and its resistance, combined with the resistance of the equipment, is equivalent to the overall resistance of the aerosol.

[0031] As an optional implementation, see Figures 1-3 As shown, there is a non-zero angle between the axis of filter 5 and the axis of housing 1.

[0032] The above structure is similar in shape to an aerosol medication device, which more realistically simulates the pressing and inhalation actions of a user when using an aerosol medication device, making it easier to teach users how to use medication.

[0033] As an optional implementation, see Figure 2 As shown, a limiting plate 11 is fixed inside the outer shell 1, and a buckle 34 is provided at the bottom of the pressing part 3. When the elastic reset member 4 is in its original state, the buckle 34 abuts against the limiting plate 11.

[0034] See Figure 2 As shown, when the pressing part 3 is not pressed, the engaging structure between the latch 34 and the limiting plate 11 prevents the pressing part 3 from dislodging from the outer casing 1. See also Figure 2 As shown, when the pressing part 3 is pressed down, the buckle 34 on the pressing part 3 drops, the elastic reset member 4 is compressed, and provides a reverse force to the pressing part 3, simulating the resistance when the medicine is pressed.

[0035] As an optional implementation, see Figure 2 and Figure 3 As shown, a rod 33 is fixed inside the pressing part 3, and a detection switch 6 is fixed inside the outer casing 1. The detection switch 6 is located on the moving path of the rod 33. In the initial state, the rod 33 is located above the detection switch 6. The rod 33 can descend to the position of the detection switch 6 when pressed by an external force. The detection switch 6 is used to detect whether the pressing part 3 is pressed in place.

[0036] The aforementioned detection switch 6 can be a photoelectric switch or a tactile switch in the prior art. The photoelectric switch can be Sensirion SFM3020, and the tactile switch can be KA1W6×5-40 (Gaochengtai Electronics), etc. Whether it is a photoelectric switch or a tactile switch, the rod 33 fixed on the pressing part 3 can trigger the detection switch 6 by blocking the light path of the photoelectric switch or touching the tactile switch. When the rod 33 triggers the detection switch 6, it can be set to press the pressing part 3 into place.

[0037] As an optional implementation, see Figure 2 and Figure 3 As shown, a positioning post 12 is fixed inside the outer casing 1. The upper end of the positioning post 12 is an open end 121. An elastic reset member 4 is sleeved on the positioning post 12. A pressing part 3 is covered outside the positioning post 12. A detection switch 6 is fixed on the inner wall of the positioning post 12. The rod 33 can descend from the open end 121 to the position of the detection switch 6 under the action of external force.

[0038] The structure of the positioning post 12 is convenient for installing and fixing the detection switch 6, and also facilitates the rod 33 to extend into it to trigger the detection switch 6. It also facilitates the positioning of the elastic reset member 4. The structure is compact and stable.

[0039] As an optional implementation, see Figure 2 and Figure 3 As shown, the pressing part 3 is provided with a receiving cavity 35, and a micro vibration motor 10 is fixed in the receiving cavity 35. The micro vibration motor 10 is a mature technology in the prior art, and its structure will not be described in detail here. Specifically, the micro vibration motor 10 can adopt the Nidec CA series in the prior art, such as CA-3×10.3, Mabuchi 22SLL1-A, etc.

[0040] Specifically, the pressing part 3 includes a pressing shell 31 and a pressing cap 32, wherein: the pressing shell 31 is slidably connected to the outer shell 1, the pressing cap 32 is located outside the outer shell 1 and fixed to the upper end of the pressing shell 31, and the pressing cap 32 and the pressing shell 31 enclose an accommodating cavity 35. Specifically, the pressing cap 32 is made of silicone material.

[0041] The pressure cap 32 is installed on the top of the receiving cavity 35. The structure of the pressure cap 32 and the pressure shell 31 forms a receiving cavity 35 that can accommodate the micro vibration motor 10. When the micro vibration motor 10 vibrates in the receiving cavity 35, the pressure cap 32 can vibrate, which can prompt the patient to start pressing and simulate the process of pressing to administer medication.

[0042] As an optional implementation, see Figure 3 As shown, a main control board 7 and a flow sensor 8 are fixed inside the housing 1. The flow sensor 8 is fixed on the main control board 7 and located in the airflow channel. The control unit on the main control board 7 is electrically connected to the flow sensor 8 and the micro vibration motor 10, and is used to control the micro vibration motor 10 to vibrate when the gas flow reaches the target value.

[0043] The flow sensor 8 can use existing models such as the FS4001 series (SIARGO, USA) and SFM3020 (Sensirion, Switzerland), which are mature technologies and will not be elaborated upon here. See also Figure 3 As shown, during medication training, airflow enters the device through the inhalation inlet 9, passes through the flow sensor 8, and then through the filter 5 into the patient's mouth. The flow sensor 8 measures the airflow rate. The size of the inhalation inlet 9 is set to simulate the original size of the medication's inlet 9, taking into account the resistance of the filter cotton 51. During training, the patient holds the mouthpiece 2 in their mouth and begins to inhale. When the airflow reaches a flow rate of 8 L / min (this value is not limited), the vibration motor 10 begins to vibrate, prompting the patient to begin pressing the medication. Then, the voice module 71 continuously prompts the patient based on the inhalation duration until the required inhalation duration of 3 seconds is reached. Of course, the specific flow rate and time values ​​mentioned above are only examples. Adjustments can be made around these values, but for various medications, the range of variation is not large. The goal is to meet the requirements of airflow and pressure for press-based medication administration.

[0044] This embodiment of the training device for simulating an aerosol medication administration device, for example, involves the user holding the mouthpiece 2 in their mouth and inhaling. When the airflow reaches a flow rate of 8 L / min, the vibration motor 10 begins to vibrate, prompting the patient to begin pressing the pressure point for medication administration. The user presses the pressure point 3, and the voice module 71 continuously prompts the patient based on the inhalation duration until the required inhalation time of 3 seconds is reached. This simulates the use of an aerosol medication administration device, ensuring that when the patient uses a real aerosol medication administration device in the future, they are familiar with how to coordinate their hands and mouth to ensure that the medication is correctly inhaled, reaches the lesion site, and achieves the corresponding therapeutic effect. Of course, the specific flow rate and time values ​​mentioned above are only examples, and adjustments can be made around these values. However, for various medications, the range of variation for these values ​​is not large; the purpose is to meet the requirements of airflow and pressure for press-based medication administration.

[0045] Specifically, the hardware connection method uses existing mature technologies, which will not be elaborated here.
