[0002] Dry Powder Inhalers (DPIs) are a common type of oral inhalation product used to treat respiratory diseases. They have the advantages of good coordination, wide prescription, and portability, but they also have obvious disadvantages, such as low efficiency of drug powder delivery. The drug dose delivered to the lungs by DPIs depends largely on the patient's inhalation flow rate and method, and patients are prone to operating errors or low inhalation flow rates when using the device, which will directly affect the treatment effect. Therefore, based on the DPIs used by patients, corresponding trainers are developed for patient training. At the same time, the patient's operating steps and inhalation flow rate can be evaluated, which can effectively reduce the error rate of device use, improve drug dosage and treatment effect.

[0043] In order to thoroughly understand the present application, detailed steps and detailed structures will be presented in the following description to illustrate the technical solution of the present application. The preferred embodiments of the present application are described in detail below, but in addition to these detailed descriptions, the present application may also have other implementation methods.

[0044] This embodiment provides a training whistle, such as Figure 1 As shown, it includes: an air vibration sound-generating element 1. Figure 2 , Figure 5 As shown, the air vibration sound-generating element 1 can be accommodated in the capsule chamber 101; the air vibration sound-generating element 1 includes an air inlet hole 15 and a sound-generating hole 16, the air inlet hole 15 is used to connect to the air inlet 103 of the capsule chamber 101, and the sound-generating hole 16 is connected to the interior of the capsule chamber 101, wherein when there is airflow flowing inside the capsule chamber 101, the air vibration sound-generating element 1 vibrates and makes sound.

[0045] The training whistle of this embodiment has a sound-generating mechanism in which the air vibration sound-generating element 1 vibrates and generates sound when air enters from the air inlet 15 and is discharged from the sound-generating hole 16. With the above mechanism, the training whistle of this embodiment can be placed in a powder inhaler to train the patient to control the inhalation strength of the powder inhaler.

[0046] When the patient performs inhalation training on the powder inhaler with the training whistle, if the whistle can be clearly heard, it means that the inhalation force meets the requirements, and inhaling with the same force when taking the medicine in reality will ensure the effect of the medicine. If the whistle cannot be clearly heard, it means that the inhalation force is not strong enough, and the effect of inhaling with the same force when taking the medicine in reality is difficult to ensure. The inhalation force directly affects the air flow rate in the capsule compartment, and the air flow rate is directly related to the sound size of the sound hole 16. In order to make the training whistle of this embodiment just make a sound under a specific inhalation force, the air inlet hole 15, the sound hole 16, and the internal structure and position of the air vibration sound element 1 of the training whistle of this embodiment can be adjusted through experiments. For example, the training whistle provided in this embodiment is designed to start to sound when the airflow rate at the nozzle outlet of the powder inhaler is ≥20L / min.

[0047] Since the specifications and sizes of existing capsules are uniformly designed with reference to T / CNPPA 3008-2020 (Specifications, Sizes and Appearance Quality of Hollow Capsules) issued by the China Medical Package Association, the specifications of the capsule compartments of existing powder inhalers are also specific, so the training whistle of this embodiment can be used for various powder inhalers of the same specification. For example, the size of the training whistle of this embodiment corresponds to the following capsules. The capsule specification model is 3#, and the dimensions are as follows: length: capsule cap 7.90-8.30mm, capsule body 13.40-13.80mm (limit deviation ±0.40mm); single arm thickness: 0.080-0.105mm (limit deviation ±0.020mm); outer diameter of the mouth: capsule cap 5.74-5.92mm, capsule body 5.48-5.66mm. That is, powder inhalers with a capsule specification model of 3# can be trained using the training whistle described above in this embodiment. It can be understood that the size of the training whistle of this embodiment is not limited to the corresponding capsule model 3#.

[0048] The training whistle provided in this embodiment uses the air vibration sound-generating element 1 that can be placed in the capsule compartment of the powder inhaler, and can realistically simulate the operation of placing capsules in the capsule compartment 101 when the patient uses the powder inhaler, so that the patient can conveniently become familiar with the opening and closing operations of the capsule compartment 101 of the powder inhaler. The training whistle provided in this embodiment is directly placed in the capsule compartment 101 for use, and can simulate the air flow conditions in the capsule compartment 101 when the capsule is actually placed, which is consistent with the air flow conditions in the capsule compartment 101 during actual medication, and realizes the inhalation strength training of the user when using the powder inhaler.

[0049] In an optional embodiment, if Figure 2 , Figure 5As shown, the training whistle also includes a first support member 13, which is connected to the air vibration sound-generating element 1 and is used to support the air vibration sound-generating element 1 in the capsule compartment 101, so that the air vibration sound-generating element 1 maintains a distance from the bottom of the capsule compartment 101. In this optional solution, the first support member 13 is provided to make the air vibration sound-generating element 1 in a relatively fixed position in the capsule compartment 101, to ensure that the air vibration sound-generating element 1 maintains a distance from the bottom of the capsule compartment 101, to avoid too small air intake at the air inlet 103 (when the air inlet 103 is shielded by the air vibration sound-generating element 1, the air intake in the capsule compartment 101 becomes significantly smaller), to ensure that the air flow in the capsule compartment 101 is in a more stable state, and to ensure that the sound-generating hole 16 can make sounds normally. The first support member 13 is composed of components such as support blocks, support rods, support sheets, springs, etc. that can support an object, as long as it can support the air vibration sound-generating element 1 in the capsule compartment 101 so that the air vibration sound-generating element 1 can be in a relatively stable position. In order to make the training whistle of this embodiment just make a sound under a specific inhalation force, the distance can also be adjusted through experiments.

[0050] In an optional embodiment, the first support member 13 is connected to the air vibration sound-generating element 1 and is used to support the air vibration sound-generating element 1 in the capsule compartment 101. The first support member 13 at least includes an elastic structure, such as Figure 5 As shown, the elastic structure can be compressed to make the air vibration sound-generating element 1 close to the bottom of the capsule compartment 101, as shown in FIG. Figure 7 As shown, the elastic structure can rebound to keep the air vibration sound-generating element 1 away from the bottom of the capsule bin 101. In this optional solution, on the first hand, by using the setting of the first support member 13, the air vibration sound-generating element 1 is in a relatively fixed position in the capsule bin 101, ensuring that the air vibration sound-generating element 1 keeps a distance from the bottom of the capsule bin 101, avoiding too small air intake of the air inlet 103 (when the air inlet 103 is shielded by the air vibration sound-generating element 1, the air intake in the capsule bin 101 is significantly reduced), ensuring that the air flow in the capsule bin 101 is in a more stable state, and also ensuring that the sound-generating hole 16 can make a sound normally; on the second hand, by using the rebound function of the elastic structure of the first support member 13, the air vibration sound-generating element 1 can automatically move away from the bottom of the capsule bin 101 after the external force is removed, so as to facilitate the removal of the air vibration sound-generating element 1.

[0051] In an optional embodiment, if Figure 2 , Figure 5As shown, the air inlet 15 is located at the bottom of the air vibration sound-generating element 1, and the first support member 13 is connected to one end of the air vibration sound-generating element 1 having the air inlet 15 (hereinafter referred to as the lower end for convenience of description), and the first support member 13 is used to abut the bottom of the capsule compartment 101, so that the air inlet 15 and the bottom of the capsule compartment 101 maintain a first preset distance. The first support member 13 includes at least an elastic structure, such as Figure 5 As shown, the elastic structure can be compressed to make the air vibration sound-generating element 1 close to the bottom of the capsule compartment 101, as shown in FIG. Figure 7 As shown, the elastic structure can rebound to keep the air vibration sound-generating element 1 away from the bottom of the capsule compartment 101. In this optional solution, a structure in which the first support member 13 is directly provided at one end of the air inlet hole 15 of the air vibration sound-generating element 1 is adopted to ensure that the air inlet hole 15 is kept at a distance from the bottom of the capsule compartment 101. This support method has high reliability, and the control of the first preset distance is also very simple, as long as the first support member 13 is allowed to abut against the bottom of the capsule compartment 101. On the one hand, by utilizing the setting of the first support member 13, the air vibration sound-generating element 1 is in a relatively fixed position in the capsule compartment 101, ensuring that the air vibration sound-generating element 1 maintains a distance from the bottom of the capsule compartment 101, avoiding too small air intake at the air inlet 103 (when the air inlet 103 is blocked by the air vibration sound-generating element 1, the air intake in the capsule compartment 101 becomes significantly smaller), ensuring that the air flow in the capsule compartment 101 is in a more stable state, and ensuring that the sound-generating hole 16 can make sounds normally; on the other hand, by utilizing the rebound function of the elastic structure of the first support member 13, the air vibration sound-generating element 1 can automatically move away from the bottom of the capsule compartment 101 after the external force is removed, so as to facilitate the removal of the air vibration sound-generating element 1; on the third hand, the air inlet 15 and the air inlet 103 are directly opposite, the air intake of the air inlet 15 is large, the vibration sound-generating effect of the air vibration sound-generating element 1 is better, the feedback to the patient during the inhalation training is more obvious, and it is conducive to the training. In other embodiments, the solution of providing a support member at the bottom of the capsule compartment 101 may not be adopted, for example, the air vibration sound-generating element 1 may be supported in the capsule compartment 101 in a suspended manner.

[0052] In an optional embodiment, if Figure 2 , Figure 5As shown, the training whistle also includes a second support member 14, the inner side of the second support member 14 is connected to the air vibration sound-generating element 1, and the outer side of the second support member 14 is used to abut the side wall of the capsule compartment 101 so that the sound-generating hole 16 and the side wall of the capsule compartment 101 maintain a second preset distance. In this optional solution, the second support member 14 directly separates the sound-generating hole 16 from the side wall of the capsule compartment 101. This support method has high reliability, and the control of the second preset distance is also very simple, as long as the second support member 14 abuts the side wall of the capsule compartment 101. The air vibration sound-generating element 1 is kept perpendicular to the bottom of the compartment in the capsule compartment 101 and does not deviate from the center of the capsule compartment 101. In other embodiments, the solution of setting a support member on the side wall of the capsule compartment 101 may not be adopted. For example, some support members are used to support the bottom of the compartment so that the air vibration sound-generating element 1 does not tilt relative to the bottom of the compartment, and the distance between the sound-generating hole 16 and the side wall of the capsule compartment 101 can also be maintained.

[0053] In an optional embodiment, the first support member 13 includes at least an elastic structure, such as Figure 5 As shown, the elastic structure can be compressed to make the air vibration sound-generating element 1 close to the bottom of the capsule compartment 101, as shown in FIG. Figure 7 As shown, the elastic structure can rebound to keep the air vibration sound-generating element 1 away from the bottom of the capsule compartment 101. This structural design is intended to improve the convenience of taking the training whistle out of the capsule compartment 101. Since the training whistle of this embodiment has a second support member 14 for stabilizing the position, it may be difficult to take the air vibration sound-generating element 1 out of the capsule compartment 101. The elastic structure provided in this optional solution can significantly improve the difficulty of taking out the training whistle of this embodiment. The specific principle is: the first support member 13 includes a part of the elastic structure and a part of the fixed structure, such as a spring and a spring fixing structure fixed to the lower end of the air vibration sound-generating element 1; it can also be an elastic structure as a whole, for example, the material of the first support member 13 itself is an elastic material, such as plastic, rubber, silicone, etc. Figure 7 As shown, when the first support member 13 is not subjected to top pressure, it is at its original length, and the total height of the first support member 13 plus the air vibration sound-generating element 1 is greater than the depth of the capsule compartment 101. When the first support member 13 is subjected to top pressure, as shown in FIG. Figure 5 As shown, since the first support member 13 is compressed, the total height of the first support member 13 plus the air vibration sound-generating element 1 is less than the depth of the capsule compartment 101, so the top of the air vibration sound-generating element 1 can be submerged below the opening 1011 of the capsule compartment 101. It can be understood that the first support member 13 is in a compressed state at this time, its length is less than the original length, and it has elastic potential energy. When the external force is removed, the first support member 13 can restore its original length, so that the top of the air vibration sound-generating element 1 emerges from the opening 1011 of the capsule compartment 101, which can greatly facilitate the user to take out the air vibration sound-generating element 1.

[0054] In an optional embodiment, the second support member 14 is located at one end of the air vibration sound-generating element 1 away from the bottom of the capsule compartment 101 (hereinafter referred to as the upper end for the convenience of description); the second support member 14 has at least the following relative to the side wall of the capsule compartment 101: in a first state, the elastic structure is in a compressed state, and the second support member 14 abuts against the side wall of the capsule compartment 101 away from the bottom of the compartment; in a second state, the elastic structure is in a rebound state, and the second support member 14 is out of contact with the side wall of the capsule compartment 101 away from the bottom of the compartment. In this optional embodiment, the position of the second support member 14 is selected at the upper end of the air vibration sound-generating element 1. Under such a setting, Figure 7 As shown, when the first support member 13 can restore its original length, the second support member 14 emerges from the opening 1011 of the capsule compartment 101. At this time, the air vibration sound-generating element 1 is freed from the limit in the capsule compartment 101, and the air vibration sound-generating element 1 can be easily taken out or poured out of the capsule compartment 101. Figure 5 As shown, when downward pressure is applied to the upper end of the air vibration sound-generating element 1, the second support member 14 can be immersed in the capsule chamber 101 and supported on the side wall of the capsule chamber 101, playing a limiting role, ensuring that the air vibration sound-generating element 1 maintains a second preset distance from the side wall of the capsule chamber 101.

[0055] In an optional embodiment, if Figure 1 As shown, the elastic structure is a flexible column 131, and the flexible column 131 can be compressed or rebounded along the height direction of the column. The material of the flexible column 131 is plastic, rubber, silicone, etc. The shape of the flexible column 131 is not limited, and it can be an equal-diameter or non-equal-diameter cylinder, a prism or a special-shaped structure. The original state of the flexible column 131 is cylindrical. In the compressed state when being compressed, the flexible column 131 can maintain the cylindrical shape or bend, but both are elastic deformations.

[0056] In an optional embodiment, if Figure 1 As shown, the number of the first support members 13 is three or more, for example: three, four, five or six, etc. Three or more first support members 13 are arranged around the air inlet 15. Under this structure, the distribution of the first support members 13 is more uniform, and the arrangement in multiple directions can ensure that the air inlet 15 maintains a first preset distance from the bottom of the capsule compartment 101. When the first support member 13 is an elastic member, the arrangement of such a surrounding distribution structure is conducive to the stability of the rebound of the air vibration sound-generating element 1, so that the rebound force of the air vibration sound-generating element 1 at multiple positions is uniform, and the air vibration sound-generating element 1 is prevented from tilting during rebound.

[0057] In an optional embodiment, if Figure 1As shown, the second support member 14 includes a support ring 141 and a plurality of connecting rods 142. The outer wall profile of the support ring 141 matches the side wall profile of the capsule compartment 101; a plurality of connecting rods 142 are connected between the air vibration sound-generating element 1 and the support ring 141, and there are gaps between adjacent connecting rods 142 for airflow to pass through. In this solution, the circular shape of the support ring 141 can better match the inner wall shape of the capsule compartment 101, and play a more balanced supporting effect, so that the air vibration sound-generating element 1 is located in the center of the capsule compartment 101. The gaps between the connecting rods 142 can provide the necessary space for airflow circulation without affecting the normal sounding of the training whistle.

[0058] The support ring 14 may be a polygonal ring, a circular ring, an elliptical ring, etc., but is not limited thereto. The outer wall contour of the support ring 141 matches the side wall contour of the capsule compartment 101, which means that, for example, if the side wall contour of the capsule compartment 101 is a circle, the outer wall contour of the support ring 141 is an inscribed polygon of the circle or a circle of the same size; for another example, if the side wall contour of the capsule compartment 101 is a polygon, the outer wall contour of the support ring 141 is the same polygon.

[0059] In an optional embodiment, if Figure 1 As shown, the air vibration sound-generating element 1 is a capsule-shaped structure. With this design, the training whistle of this embodiment can be more consistent with the shape of the capsule. On the one hand, the patient feels closer to the capsule during training, which improves the realism of the training. On the other hand, the training whistle of this embodiment is more consistent with the real capsule in terms of aerodynamics, and can highly simulate the gas flow environment in the capsule compartment 101 of the powder inhaler when the capsule is actually placed, so as to ensure that the training effect of the training whistle of this embodiment is more reliable, and avoid the situation that the medication effect of the patient does not match the training effect when taking the medicine in real life.

[0060] In an optional embodiment, the air vibration sound-generating element 1 includes: a main body 11 and a cap body 12. The main body 11 is hollow inside; the cap body 12 is hollow inside, and its cover is arranged at one end of the main body 11; the cap body 12 is connected to the internal hollow of the main body 11. It can be understood that the common internal hollow area of ​​the cap body 12 and the main body 11 forms a space in which air can flow and vibrate. In this embodiment, the main body 11 and the cap body 12 are designed to imitate the shape of the capsule on the one hand, and on the other hand, form a detachable structure to facilitate structural design and replacement of the main body 11 or the cap body 12. The air inlet 15 and the sound-generating hole 16 can be both arranged on the main body 11 or both arranged on the cap body 12, or one of them can be arranged on the main body 11 and the other on the cap body 12.

[0061] In an optional embodiment, a resonance cavity 17 is formed inside the air vibration sound-generating element 1, and the resonance cavity 17 is connected to the air inlet 15 and the sound-generating hole 16 respectively. The function of the resonance cavity 17 is to generate air vibration when air flows. Figure 2 As shown, the main body 11 has a wedge block 18 inside, and the shape design of the wedge block 18 can change the air vibration effect of the resonance chamber 17, and further can affect the minimum air flow velocity required for the training whistle to make a sound. Therefore, it can be seen that if necessary, by replacing the main body 11 with a different wedge block 18 design, the training whistle can change the training of different inhalation forces of the patient.

[0062] The present embodiment provides an existing powder inhaler, including a dust cap, a mouthpiece part, a main body part, and a piercing button.
