Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of airflow analysis test of drug powder, and particularly to a transfer device, a transfer assembly and a drug powder measuring system. BACKGROUND

[0002] The airflow analysis test of drug powder can evaluate the inhalation performance of the drug. The airflow analysis test of the airflow type drug dispensing device (such as an inhaler) and the like can evaluate the performance of the device and the delivery and deposition of the drug in the respiratory system to ensure that the patient can effectively inhale the drug particles when using the device.

[0003] However, in the airflow analysis test of the airflow type dispensing device such as the inhaler, on the one hand, it is necessary to ensure that the amount of the drug powder is a certain dose, and on the other hand, it is necessary to form an airflow. This leads to the fact that only the consumptive test of sampling can be carried out by using the inhaler itself. This method needs to complete the development of the inhaler, and the consumptive test causes waste of resources, and even many manufacturers do not test or test individually before leaving the factory. For users, it is easy to cause the treatment effect to be unsatisfactory.

[0004] Therefore, how to simulate the test of the airflow dispensing device without using the device itself is a problem to be solved by those skilled in the art. SUMMARY

[0005] In view of the above-mentioned shortcomings of the related art, the purpose of the present application is to provide a transfer device, a transfer assembly and a drug powder measuring system to overcome the technical problem that only consumptive test can be carried out when the airflow analysis test of the airflow type drug dispensing device is carried out in the related art.

[0006] To achieve the above-mentioned purpose and other related purposes, the first aspect of the present application provides a transfer device suitable for storing or transferring a drug powder measuring rod. The transfer device comprises a base provided with a containing cavity for receiving the drug powder measuring rod, and an operating section of the drug powder measuring rod protrudes from the containing cavity for operation when the drug powder measuring rod is inserted into the containing cavity; a frame for supporting the base, which can move relative to the base to lock the drug powder measuring rod, and the operating section of the drug powder measuring rod cannot be operated in the locked state, so that the drug powder measuring rod is stored on the base or transferred with the base.

[0007] The second aspect of the present application provides a transfer assembly, comprising: a first transfer device for storing or transferring a first drug powder measuring rod; and a second transfer device for storing or transferring a second drug powder measuring rod; wherein the first transfer device or the second transfer device is configured as the transfer device in any one of the embodiments disclosed in the first aspect of the present application.

[0008] The third aspect of the present application provides a powder measuring system, comprising: a powder measuring rod for containing a preset amount of powder; a powder filling device for receiving the powder measuring rod to fill powder into the powder measuring rod; a transfer device for receiving the powder measuring rod containing powder to store or transfer the powder measuring rod, which is configured as the transfer device in any one of the embodiments disclosed in the first aspect of the present application; and a simulated inhalation device for receiving the powder measuring rod to interface with the powder measuring rod, and when interfacing, the powder in the dose slot of the powder measuring rod carried by the airflow is guided from the chamber inlet to the chamber outlet of the simulated inhalation device to complete a test operation.

[0009] In summary, the transfer device, transfer assembly and powder measuring system provided by the present application can accommodate a preset amount of powder by providing a powder measuring rod, thereby achieving the accuracy of the test dose; the preset amount of powder in the powder measuring rod can be filled by providing a powder filling device, thereby further achieving the accuracy of the test; the storage and transfer of the powder measuring rod can be achieved by providing a transfer device, which can avoid the loss and pollution of the powder; the formation of airflow and the interfacing with the powder measuring rod for drug dispensing can be achieved by providing a simulated inhalation device; the airflow analysis test for the airflow type dispensing device such as an inhaler can be achieved by the synergistic effect of the powder measuring rod, the powder filling device, the transfer device and the simulated inhalation device, thereby avoiding the consumable test using the inhaler itself.

Thus, the present application is not intended to be limited to the embodiments shown, but is to be accorded the widest scope consistent with the claims.

[0033] In the following description, reference is made to the accompanying drawings which form a part hereof, and which is shown by way of illustration of several embodiments of the present application. It is understood that other embodiments can be used and structural, electrical, and operational changes can be made without departing from the spirit and scope of the present disclosure. The following detailed description is, therefore, not to be taken in a limiting sense, and the scope of the embodiments of the present application is defined by the appended claims. The summary of the application does not purposely limit the application's scope. Spatially relative terms, such as "upper", "lower", "left", "right", "below", "below", "bottom", "top", and the like, can be used herein for ease of description to describe one element or feature's relationship to another element(s) or feature(s) as illustrated in the figures. It will be understood that the spatially relative terms are intended to encompass different orientations of the device in use or operation in addition to the orientations depicted in the figures. For example, if the device described herein is turned over in use, a relative prefiix term such as "upper", "lower", "front", "back", etc. can be used to describe the same parts or features of the device. The device can also be oriented in the opposite direction (in a mirror image) with the same or opposite relative prefiix terms applied, depending on the circumstances. The spatially relative terms in the claims have the same meaning as those with respect to the description. The application has other embodiments with out the scope of which the application is not intended to be limited.

[0034] While in some examples the terms first, second, etc. are used herein to describe various elements, these elements should not be limited by these terms. These terms are only used to distinguish one element from another. For example, a first medicament powder measuring rod can be termed a second medicament powder measuring rod, and, similarly, a second medicament powder measuring rod can be termed a first medicament powder measuring rod, without departing from the scope of the various described embodiments. The first medicament powder measuring rod, the second medicament powder measuring rod are both describing a medicament powder measuring rod, but they are not the same medicament powder measuring rod unless the context clearly indicates otherwise. Similar cases include first recess and second recess, first medicament powder and second medicament powder, etc.

It will be further understood that the terms "comprises", "comprising", "includes" and / or "including", when used herein, specify the presence of stated features, steps, operations, elements, components, items, and / or groups thereof, but do not preclude the presence or addition of one or more other features, steps, operations, elements, components, items, and / or groups thereof. As used herein, the term "and / or" and "or" is construed to include both "and" and "or" unless an item is introduced with an "exclusive or" conjunction. Thus, "A, B, or C" or "A, B, and / or C" means "any of the following: A; B; C; A and B; A and C; B and C; A, B, and C." An exception to this definition will occur only when a combination of elements, functions, steps or acts are in some way inherently mutually exclusive.

[0036] In view of the technical problems mentioned in the background art, the present application discloses a medicine powder measuring rod, a medicine powder measuring rod assembly, a medicine powder filling device, a medicine powder filling assembly, a transfer device, a transfer assembly, a simulation inhalation device and a medicine powder measuring system. By arranging the medicine powder measuring rod, the pre-set amount of medicine powder is accommodated, thereby realizing the accuracy of the test dose. By arranging the medicine powder filling device, the pre-set amount of medicine powder in the medicine powder measuring rod is filled, thereby further realizing the accuracy of the test. By arranging the transfer device, the storage and transfer of the medicine powder measuring rod are realized, which can avoid the loss and pollution of the medicine powder. By arranging the simulation inhalation device, the airflow can be formed, and the simulation inhalation device can be docked with the medicine powder measuring rod to distribute the medicine. Through the synergistic effect of the medicine powder measuring rod, the medicine powder filling device, the transfer device and the simulation inhalation device, the airflow analysis test of the airflow type distribution device such as the inhaler can be realized, thereby avoiding the consumptive test of using the inhaler itself.

The side close to the operation platform (also can be called as the support surface, the operation surface, etc.) is defined as the lower side or the lower side, and the side away from the operation platform is defined as the upper side or the upper side, and the plane on which the operation platform is located is defined as the horizontal plane (also can be called as the horizontal direction), and the plane perpendicular to the horizontal plane is defined as the vertical plane (also can be called as the vertical plane, the vertical direction or the vertical direction). It should be understood that the orientation defined herein does not represent an absolute position, but a relative position.

[0038] The operator refers to a person or a machine that operates various components, structures, assemblies, mechanisms, devices or the like. The person may, for example, be a professional responsible for performing analysis test, collecting data or ensuring the accuracy and smoothness of the test process, for example, a test engineer, a laboratory technician or a data collector, etc. The machine may, for example, include a mechanical arm. In subsequent embodiments, the operator is taken as an operator for illustration, which should not be understood as a limitation of the present application.

[0039] The operation platform refers to a platform or a workbench for placing or supporting these components, structures, assemblies, mechanisms, devices or the like, which may, for example, be a table, an experimental bench, a weighing table, etc.

[0040] In some embodiments, the present application discloses a powder measuring system, which comprises a powder measuring rod, a powder filling device, a transfer device, and a simulation inhalation device. It is to be noted that the number and type of the powder measuring rod, the powder filling device, the transfer device, and the simulation inhalation device included in the powder measuring system disclosed by the present application are not limited, for example, in some embodiments, the powder measuring system can also comprise a powder measuring rod assembly, a powder filling assembly, a transfer assembly, and a simulation inhalation device, wherein the powder measuring rod assembly comprises at least two powder measuring rods, the powder filling assembly comprises at least two powder filling devices, and the transfer assembly comprises at least two transfer devices.

[0041] The following embodiments will be described in detail below to illustrate the powder measuring rod and rod assembly, the powder filling device and filling assembly, the transfer device and transfer assembly, and the simulation inhalation device disclosed by the present application. Figures 1 to 21

[0042] In some embodiments, the present application discloses a powder measuring rod for containing a preset amount of powder. Please refer to Figure 1 , which shows a structural schematic diagram of the powder measuring rod in an embodiment of the present application, as Figure 1 shown, the powder measuring rod 1 comprises a rod 11 and a dose groove 12. The rod 11 further comprises a rod body 110, an operation section 111 located at the proximal end of the rod body 110, and a measuring section 112 located at the distal end of the rod body 110. The dose groove 12 is arranged on the circumferential surface of the measuring section 112 for containing a preset amount of powder. When the rod 11 is transferred to a docking simulation inhalation device through the operation section 111, the dose groove communicates with the chamber inlet of the simulation inhalation device to enable the airflow to carry the powder in the dose groove from the chamber inlet to the chamber outlet of the simulation inhalation device to complete the test operation. The structure of the simulation inhalation device will be described in detail later.

[0043] Figure 1 The shape of the rod 11 shown is only a schematic representation. In embodiments, the rod includes but is not limited to a straight rod and a curved rod, and the cross section thereof includes but is not limited to a circle, a circle-like shape, a polygon, and a polygon-like shape, as long as it can be inserted or docked with other devices or equipment, etc.

[0044] The operation section provides an operation space for the operator, who can operate the powder measuring rod by holding the operation section, for example, to perform operations such as transfer, placement, insertion, rotation, docking, etc. that require contact with the powder measuring rod. In an embodiment, the operation section can be configured as a handle arranged at the proximal end of the rod body, which is operated by the operator to act on the powder measuring rod. In an embodiment, as Figure 1 ​As shown, the operation section 111 is configured to be formed by the rod body 110 extending along the proximal end, and the operation personnel can hold this part to operate the powder measuring rod 1, for example, the fingers of the operation personnel hold this part to operate the powder measuring rod 1.

[0045] In an embodiment, as shown in Figure 1 the operation section 111 is provided with a holding part 113 for holding the rod 11. That is, the operation personnel can hold the powder measuring rod 1 by holding the holding part 113. Further, the holding part 113 can be configured as a recess structure formed on the circumferential surface of the operation section 111, which provides a holding space where the fingers of the operation personnel can be located. In an example, the recess structure is configured as a recess formed downwardly on the circumferential surface of the operation section, and the fingers of the operation personnel can be placed in the recess to facilitate the operation. In another example, the recess structure can also include a first recess and a second recess, which are oppositely distributed on the circumferential surface of the operation section for holding, for example, the thumb of the operation personnel can be placed in the first recess, and the index finger or the middle finger can be placed in the second recess to facilitate the gripping and transferring of the powder measuring rod. For example, the first recess and the second recess can be oppositely distributed on the circumferential surface of the operation section left and right, or oppositely distributed on the circumferential surface of the operation section up and down. It should be understood that the holding part 113 can be provided at any position of the operation section 111 as long as it can be gripped by the operation personnel, and of course, the holding part 113 can also not be provided, and the operation personnel can directly grip the operation section.

[0046] In an embodiment, please continue to refer to Figure 1 the measurement section 112 can be configured to be formed by the rod body 110 extending along the distal end, and the dose groove 12 can be configured as a groove formed downwardly on the measurement section 112. Of course, in other embodiments, the measurement section can also be configured as a component connected to the distal end of the rod body, and the dose groove is a part of the measurement section.

[0047] As described above, the dose groove 12 is used to accommodate a preset amount of powder. The powder can be, for example, a single component of a drug powder or a mixed drug powder used to treat asthma and other respiratory inflammatory diseases, such as atropine, budesonide, salmeterol, etc. or any combination thereof. The preset amount refers to a single dose amount that can produce a therapeutic effect of a drug or a single component in a mixed powder that can produce a therapeutic effect. In an embodiment, the preset amount can be configured to be any value not greater than 30 μl, for example, 5 μl, 8 μl, 10 μl, 15 μl, 18 μl, 20 μl, 25 μl, 30 μl, etc. Preferably, the preset amount is configured to be 5 μl to 20 μl. It should be understood that according to the accommodation volume of the dose groove corresponding to the preset amount and the shape of the dose groove, the size of the dose groove should be set.

[0048] In an embodiment, as shown in Figure 1 , the dose well 12 is configured to have a near-elliptical opening. In some other embodiments, the dose well can be configured to have a circular opening, a square opening, or a V-shaped opening, but not limited thereto, depending on actual needs and manufacturer's design selection.

[0049] In order to facilitate the powder falling to the bottom of the dose well, in an embodiment, the dose well 12 is configured to have a funnel-shaped structure with a cross-section decreasing from top to bottom. This structure can facilitate the powder being filled into the dose well on one hand, and on the other hand, it is more similar to the structure of the medicine pocket in the inhaler, which can make the airflow carry the powder distribution in a manner closer to the real device during the analysis test, thereby improving the accuracy of the test. Of course, the dose well structure can also be configured in other shapes as long as it has a corresponding accommodation volume for the preset amount of powder and can be adapted to the simulated inhalation device.

[0050] Referring to Figure 2 , a structure diagram showing the configuration of the identification structure on the powder measuring rod in an embodiment of the present application is shown, as shown in the figure, the rod 11 is configured with an identification structure 115 to provide an indication to the operator. In an example, the identification structure can be used to indicate the type of the powder measuring rod, which refers to different powder measuring rods, for example, the identification structure can distinguish the types of the powder contained in the dose well. In an example, the identification structure can be used to indicate the state of the powder measuring rod, which refers to the current situation of the powder measuring rod used by the operator to perform the operation, such as the placement state and the docking state. It should be understood that the placement state refers to the state of the powder measuring rod when it is placed on a horizontal surface, at this time, the opening of the dose well faces upward, and the identification structure is in an inclined direction. The docking state refers to the state of the powder measuring rod when it is used to complete the docking with the simulated inhalation device. In an example, the identification structure can indicate both the type of the powder measuring rod and the state of the powder measuring rod.

[0051] The identification structure includes but is not limited to color identification, number identification, letter identification, or visual identification of any combination of the above, and the way the identification structure is configured on the rod includes but is not limited to pasting, carving, labeling, laser engraving, and digital display screen. Further, in order to facilitate the observation of the operator, the identification structure can be configured on the end face of the proximal end of the rod.

[0052] In the embodiment where the identification structure is configured as a letter mark, the corresponding letter mark can be used to indicate the type of the medicine powder measuring rod. When the types of medicine powder used for analysis test are different or when it is required to mix medicine powder in different medicine powder measuring rods in the analysis test, the letter mark can be used to visually indicate the operator, who can determine which type of medicine powder is contained in the medicine powder measuring rod by observing the letter mark, so as to avoid confusion. For example, as shown in Figure 2 the end face of the rod 11 of the medicine powder measuring rod 1 is marked with a letter A, which is used to indicate that the preset amount of the first medicine powder is contained in the dose groove 12 thereof, and the end face of another medicine powder measuring rod is marked with a letter B, which is used to indicate that the preset amount of the second medicine powder is contained in the dose groove thereof, so that the operator can distinguish the two types of medicine powder measuring rods by the letters A and B.

[0053] In the embodiment where the identification structure is configured as a letter mark, the corresponding letter mark can be used to indicate the type of the medicine powder measuring rod. When the types of medicine powder used for analysis test are different or when it is required to mix medicine powder in different medicine powder measuring rods in the analysis test, the letter mark can be used to visually indicate the operator, who can determine which type of medicine powder is contained in the medicine powder measuring rod by observing the letter mark, so as to avoid confusion. For example, as shown in

[0054] Please refer to Figure 3 , which shows a schematic view of the proximal end face of the medicine powder measuring rod in an embodiment of the present application. For the convenience of description, the dose groove, which is invisible from the perspective of the proximal end face, is shown in a dashed line manner. As shown in the figure, the identification structure 115 is configured to have a preset angle with respect to the vertical direction of the dose groove 12, which is the angle a between the direction where the corresponding letter mark of the letter mark is located and the vertical direction of the dose groove 12. The preset angle can be a positive angle value or a negative angle value. The positive angle value represents the clockwise rotation (the preset angle a is marked as in Figure 3 the figure) with respect to the vertical direction of the dose groove 12, and the negative angle value represents the counterclockwise rotation with respect to the vertical direction of the dose groove 12. As shown in the embodiment of Figure 3 , the preset angle a is configured to be 45°, which represents the clockwise rotation of 45° with respect to the vertical direction of the dose groove 12. Of course, the preset angle a can also be configured to be -45°, which represents the counterclockwise rotation of 45° with respect to the vertical direction of the dose groove 12. It should be understood that the above 45° or -45° is only an example, and those skilled in the art can also configure other angles under the guidance of the present application, such as 30°, -30°, 60°, -60°, etc.

[0055] In an embodiment, the rod of the medicament powder measuring rod has a preset length, which is used to indicate the type of the medicament powder measuring rod. The preset length refers to the length of the medicament powder measuring rod which is preset. When the types of medicament powder used for analysis test are different or when different medicament powders in the medicament powder measuring rods need to be mixed in the analysis test, the preset length can visually indicate the operator that the medicament powder in the medicament powder measuring rod can be determined by observing the length of the medicament powder measuring rod, so as to avoid confusion. For example, a relatively short preset length of the rod of the medicament powder measuring rod can indicate that a preset amount of first medicament powder is contained in the dose groove thereof, and a relatively long preset length of the rod can indicate that a preset amount of second medicament powder is contained in the dose groove thereof, so that the operator can distinguish the two types of medicament powder measuring rods by the preset length of the rod.

[0056] In another embodiment, the different preset lengths also play a role in facilitating the operation of the operator when the medicament powder measuring rod is docked with the simulated inhalation device, which will be described later.

[0057] It should be noted that the method for indicating the type of the medicament powder measuring rod can be one of setting different letter marks and different preset lengths, or both methods can be used at the same time to minimize the possibility of confusion by the operator. Of course, the method for indicating the type of the medicament powder measuring rod can also be changed, for example, the rod or the end face is set to different colors, as long as the types of medicament powder in the medicament powder measuring rod can be distinguished, which belongs to the content claimed by the present application.

[0058] As shown in Figure 1 The medicament powder measuring rod 1 further comprises a positioning portion 114 arranged at the bottom side of the rod 11, which is used to support the rod 11 so that the opening of the dose groove 12 faces upward when the rod 11 is placed on a horizontal plane, and at the same time, the placement of the medicament powder measuring rod 1 on the operation table is more stable, avoiding its overturning and tilting. Please refer to Figure 4 and in combination with Figure 1 , wherein, Figure 4 The figure shows the schematic view of the proximal end face of the medicament powder measuring rod in an embodiment of the present application. In order to facilitate the description, the dose groove which is invisible from the perspective of the proximal end face is shown in a dashed line manner. As shown in the figure, the positioning portion 114 is arranged to have a preset angle compared to the vertical direction of the dose groove 12, and the preset angle is the included angle β between the axis direction of the positioning portion 114 and the vertical direction of the dose groove 12. The preset angle can be divided into a positive angle value and a negative angle value, the positive angle value represents the clockwise rotation with the vertical direction of the dose groove 12 as the starting point, and the negative angle value represents the counterclockwise rotation with the vertical direction of the dose groove 12 as the starting point. As Figure 4As shown, the preset angle β is configured as -60°, which means that the axis direction of the positioning portion 114 rotates 60° counterclockwise with the vertical direction of the dose groove 12 as the starting point. Of course, the preset angle β can also be configured as 60°, which means that the axis direction of the positioning portion 114 rotates 60° clockwise with the vertical direction of the dose groove 12 as the starting point.

[0059] In an embodiment, as shown in Figures 1 to 4 The positioning portion 114 is configured as a cylindrical structure protruding in the circumferential direction of the rod 11, which can be configured as an integral part of the rod 11. When the powder measuring rod is placed on a horizontal surface, the cylindrical structure provides point support for the rod 11. In another embodiment, the positioning portion can be configured as a protruding bump structure in the circumferential direction of the rod. In yet another embodiment, no positioning portion can be provided. For example, when designing the powder measuring rod, its structure and center of gravity can be considered so that when the opening direction of the dose groove is the vertical direction, the powder measuring rod can automatically be in a balanced state, and at this time, the stable placement of the powder measuring rod on the horizontal surface can be achieved without the aid of the positioning portion.

[0060] In order to achieve multi-channel testing of the powder or to achieve mixing testing of the powder in the airflow analysis test, different powders need to be accommodated in different powder measuring rods. In view of this, the present application discloses a powder measuring rod assembly in some embodiments, please refer to Figure 5 , which shows a schematic diagram of the powder measuring rod assembly in an embodiment of the present application, as shown in Figure 5 The powder measuring rod assembly includes a first powder measuring rod 1 and a second powder measuring rod 2. The first powder measuring rod 1 is used to accommodate a preset amount of first powder, and the second powder measuring rod 2 is used to accommodate a preset amount of second powder, thereby cooperating with the simulated inhalation device to complete the testing operation. For example, the first powder measuring rod 1 and the second powder measuring rod 2 can be respectively configured as the powder measuring rod as described in any of the embodiments of Figures 1 to 4 and the related description.

[0061] Among them, the first powder or the second powder can be configured as a drug powder for treating asthma or other respiratory inflammatory diseases. In an example, the first powder is configured to contain a bronchodilator as an active pharmaceutical ingredient, and the second powder is configured to contain an anti-inflammatory drug as an active pharmaceutical ingredient.

[0062] In order to enable the operator to distinguish the first powder and the second powder accommodated in the first powder measuring rod and the second powder measuring rod in the powder measuring rod assembly, in an embodiment, as shown in Figure 5As shown, the letter mark on the proximal end face of the first medicament powder measuring rod 1 is configured as letter A, and the letter mark on the proximal end face of the second medicament powder measuring rod 2 is configured as letter B. Of course, the letter mark on the proximal end face of the first medicament powder measuring rod 1 can be configured as letter C, and the letter mark on the proximal end face of the second medicament powder measuring rod 2 can be configured as letter D, and the present application does not limit this, as long as the first medicament powder measuring rod and the second medicament powder measuring rod can be distinguished, thereby further distinguishing the first medicament powder and the second medicament powder contained therein.

[0063] Further, the preset angle of the identification structure of the first medicament powder measuring rod 1 relative to the vertical direction of the dose groove 12 is configured to be opposite to the preset angle of the identification structure of the second medicament powder measuring rod 2 relative to the vertical direction of the dose groove 22. In Figure 5 In the embodiment shown, the preset angle of the letter A on the first medicament powder measuring rod 1 relative to the vertical direction of the dose groove 12 is 45°, and the preset angle of the letter B on the second medicament powder measuring rod 2 relative to the vertical direction of the dose groove 22 is -45°, and the directions of the two are opposite.

[0064] In an embodiment, the first medicament powder measuring rod 1 and the second medicament powder measuring rod 2 have different preset lengths, and the preset length of the second medicament powder measuring rod 2 is longer than that of the first medicament powder measuring rod 1. For example, in Figure 5 In the embodiment shown, the preset length L1 of the first medicament powder measuring rod 1 is less than the preset length L2 of the second medicament powder measuring rod 2. The preset length L2 of the second medicament powder measuring rod 2 and the preset length L1 of the first medicament powder measuring rod can differ by any value within 16mm to 20mm, such as 16mm, 16.3mm, 16.5mm, 17mm, 18mm, 19mm, 20mm, etc., so that in the visual angle of the operator, the first medicament powder measuring rod 1 is short and thick, and the second medicament powder measuring rod 2 is long and thin. It should be understood that, Figure 5 The preset length identification shown in the figure is only an illustrative description, and does not mean that the preset lengths of the two medicament powder measuring rods must be equal or unequal. For example, the relationship between the preset length L1 of the first medicament powder measuring rod 1 and the preset length L2 of the second medicament powder measuring rod 2 can also be L1>L2 or L1=L2, etc.

[0065] In an embodiment, the preset angle of the positioning portion of the first medicament powder measuring rod relative to the vertical direction of the dose groove is configured to be opposite to the preset angle of the positioning portion of the second medicament powder measuring rod relative to the vertical direction of the dose groove. Please refer to Figure 6 and in combination with Figure 5 wherein, Figure 6 shows a schematic view of the proximal end face of the medicament powder measuring rod assembly in an embodiment of the present application. As shown in Figure 6As shown, the preset angle β of the positioning part 114 of the first medicine powder measuring rod 1 relative to the vertical direction of the dose groove 12 is -60°, and the preset angle of the positioning part 214 of the second medicine powder measuring rod 2 relative to the vertical direction of the dose groove 22 is 60°.

[0066] Based on the above-mentioned differences or the combination of several differences between the first medicine powder measuring rod and the second medicine powder measuring rod, the operator can easily distinguish the first medicine powder measuring rod 1 and the second medicine powder measuring rod 2, and thus easily distinguish the first medicine powder and the second medicine powder contained therein.

[0067] In order to be able to fill a preset amount of medicine powder into the medicine powder measuring rod, for example, to fill the dose groove in the medicine powder measuring rod described in any of the preceding embodiments with a preset amount of medicine powder, the application also discloses a medicine powder filling device in some embodiments. By providing a receiving cavity and a feeding port on the body, the medicine powder measuring rod can be placed in the receiving cavity and the filling of medicine powder can be carried out through the feeding port, and the medicine powder can be accurately filled into the dose groove.

[0068] Please refer to Figure 7 , which shows the structure of the medicine powder filling device in an embodiment of the application from a perspective, as Figure 7 shown, the medicine powder filling device 3 includes a body 31 and a feeding port 32. The body 31 is provided with a receiving cavity 33 for receiving the medicine powder measuring rod. The feeding port 32 is arranged on the body 31 and communicates with the receiving cavity 33. When the medicine powder measuring rod is placed in the receiving cavity 33, the dose groove on the medicine powder measuring rod is directed towards the feeding port 32 so that the medicine powder falls into the dose groove through the feeding port 32. It should be noted that in order to distinguish the receiving cavity in the subsequent other devices or components, the receiving cavity included in the medicine powder filling device is also referred to as the first receiving cavity in the embodiment.

[0069] As shown in Figure 7 , in an embodiment, the body 31 includes a base 311 and a filling part 312. Among them, the base 311 provides a support basis, which can also be understood as the filling part 312 supported on the base 311. In an embodiment, as shown in Figure 7 , the base 311 is configured as a generally cuboid base, further, it can be flat, thereby providing stable support. In order to avoid bumping to the operator, in the example as shown in Figure 7 , the edge of the base towards the upper part is configured as an arc edge or an inclined surface edge.

[0070] In an embodiment, as shown in Figure 7As shown, the filling part 312 is configured as a cuboid-shaped main body part, which has a width smaller than that of the base part 311 and a height obviously higher than that of the base part 311. Further, in order to avoid bumping the operator, the edges of the base towards the upper side and the left and right sides can be configured as curved edges or inclined surface edges. In some examples, the filling part 312 and the base part 311 can be integrally formed or connected in a fixed connection manner, including but not limited to welding, bonding and mortise and tenon connection. In some other examples, the body of the medicine powder filling device can not be distinguished into a base part and a filling part, which is not limited in the present application.

[0071] In an embodiment, as shown in Figure 7 , the first accommodating cavity 33 and the feeding port 32 are formed on the filling part 312 of the body 31. Please refer to Figure 8 , which shows a structure schematic diagram of the medicine powder filling device in another view in an embodiment of the present application, as shown in Figure 7 and Figure 8 , the first accommodating cavity 33 is formed on the filling part 312 in a front-to-back through manner, and the feeding port 32 extends along the vertical direction on the top (or upper part) of the filling part 312 to be through with the first accommodating cavity 33. In order to facilitate the falling of the medicine powder into the dose groove, in an example, the feeding port 32 is configured as a hole structure with a continuously decreasing cross section from top to bottom, for example, a funnel-shaped hole structure, a horn-shaped hole structure, or other hole structures with inclined side walls. Of course, the feeding port can also be provided in other shapes as long as it can make the medicine powder enter the dose groove.

[0072] In an embodiment, the first accommodating cavity 33 includes a rod receiving chamber 331 for inserting the rod of the medicine powder measuring rod. In an example, the rod receiving chamber 331 is formed on the filling part 312 in a front-to-back through manner. It should be noted that in order to distinguish the rod receiving chamber included in the accommodating cavity in other devices or components, the rod receiving chamber included in the first accommodating cavity is referred to as the first rod receiving chamber in the embodiment, and similarly, the positioning groove further included in the first accommodating cavity in the subsequent embodiments is referred to as the first positioning groove, which will not be described hereinafter.

[0073] In an embodiment, the depth of the first rod receiving chamber 331 is smaller than the length of the rod of the medicine powder measuring rod, so that the operating section of the rod protrudes out of the first rod receiving chamber 331 when the rod is inserted, thereby facilitating the operator to hold the operating section to insert or pull out the medicine powder measuring rod from the first rod receiving chamber 331.

[0074] In one embodiment, the first rod receiving chamber 331 has a size that fits the rod of the medicament powder measuring rod so that when the rod is taken out, the first rod receiving chamber 331 blocks more than a preset amount of powder from being taken out by the rod. That is, the diameter of the first rod receiving chamber 331 is substantially the same as the diameter of the rod, and when the operator holds the operation section to take out the rod after the medicament powder is filled into the dose groove of the medicament powder measuring rod from the filling port 32, the first rod receiving chamber 331, due to the size limitation of the first rod receiving chamber 331 and the rod, functions as a scraper to scrape more than a preset amount of medicament powder from the rod. In this way, the operator does not need to accurately weigh the mass of the medicament powder to be filled, but only needs to roughly fill the medicament powder into the dose groove, and the accuracy of the amount of the filled medicament powder can be ensured, thereby improving the efficiency of the medicament powder filling and further improving the efficiency of the test operation.

[0075] In one embodiment, the first receiving cavity 33 further includes a first positioning groove 332 on the basis of the first rod receiving chamber 331. The first positioning groove 332 is arranged in the circumference of the first rod receiving chamber 331 and is used to cooperate with the positioning part of the medicament powder measuring rod so that when the positioning part is inserted to the end of the first positioning groove 332, the dose groove of the medicament powder measuring rod is aligned with the filling port 32. In other words, the first positioning groove 332 can limit the insertion depth of the medicament powder measuring rod by cooperating with the positioning part of the medicament powder measuring rod, and when the operator inserts the matched medicament powder measuring rod into the first receiving cavity 331 by operating the operation section of the medicament powder measuring rod, the medicament powder measuring rod can no longer be pushed to continue to be inserted when the positioning part reaches the end of the first positioning groove 332, at which time the dose groove of the medicament powder measuring rod can be just aligned with the filling port 32, thereby facilitating the operator to insert the medicament powder measuring rod into the appropriate position.

[0076] In an embodiment, the first positioning groove 332 is configured to have a preset angle with respect to the vertical direction of the feed port 32, which is consistent with the preset angle of the positioning portion on the powder measuring rod with respect to the vertical direction of the dose groove. For example, when the axis direction of the positioning portion of the powder measuring rod has a preset angle of -60° with respect to the vertical direction of the dose groove, the axis direction of the first positioning groove 332 of the powder filling device 3 also has a preset angle of -60° with respect to the vertical direction of the feed port 32; when the axis direction of the positioning portion of the powder measuring rod has a preset angle of 60° with respect to the vertical direction of the dose groove, the axis direction of the first positioning groove 332 of the powder filling device 3 also has a preset angle of 60° with respect to the vertical direction of the feed port 32. In this way, on the one hand, it can be ensured that when the rod is inserted into the first accommodating cavity 33, the first positioning groove 332 and the positioning portion fit to play a positioning role on the powder measuring rod; on the other hand, it can avoid the operator inserting the powder measuring rod which is not suitable for the powder filling device 3 into the first accommodating cavity 33, thereby avoiding the operator's incorrect filling of the powder, for example, when the axis direction of the first positioning groove 332 of the powder filling device 3 has a preset angle of -60° with respect to the vertical direction of the feed port 32, the operator cannot insert the powder measuring rod whose axis direction of the positioning portion has a preset angle of 60° with respect to the vertical direction of the dose groove into the first accommodating cavity 33.

[0077] In an embodiment, the depth of the first positioning groove 332 is configured to adapt to the size information of the feed port, the positioning portion of the powder measuring rod and the dose groove. The angle of the first positioning groove 332 is limited while the depth is limited, so that when the powder measuring rod is inserted into the first accommodating cavity 33, the dose groove on the powder measuring rod is aligned with the feed port 32 on the powder filling device 3, that is, the axis of the dose groove opening coincides with the axis of the feed port, so as to accurately fill the powder from the feed port 32 into the dose groove. In a preferred example, the depth of the first positioning groove 332 is configured to be 10 mm.

[0078] In Figure 7 In the embodiment shown, the body 31 of the powder filling device 3 is configured with an identification structure 35. The identification structure 35 is used to indicate the type of the powder filling device. The type of the powder filling device refers to different powder filling devices, and further, the identification structure 35 can distinguish the types of the powders to be filled.

[0079] The identification structure includes but is not limited to color identification, number identification, letter identification, or visual identification of any combination of the above, and the way the identification structure is configured on the body includes but is not limited to pasting, carving, labeling, laser engraving and digital display screen, and further, in order to facilitate the operator to observe, the identification structure can be configured on the end face of the proximal end of the body.

[0080] In the embodiment where the identification structure is configured as a letter, when different powders need to be filled into different powder measuring rods, the letter can visually indicate the operator, who can determine which powder needs to be filled into the feeding port by observing the letter, so as to avoid confusion. For example, as shown in Figure 7 , the operator can be indicated to fill the first powder into the feeding port 32 by the letter A on the proximal end face of the body 31 of the powder filling device 3, and the operator can be indicated to fill the second powder into the feeding port of another powder filling device by the letter B on the proximal end face of the body of the powder filling device, so that the operator can distinguish the two powders to be filled by the letters A and B.

[0081] Of course, the identification structure can be arranged at any position of the powder filling device as long as the operator can clearly realize the type of the powder to be filled, and the present application does not limit this.

[0082] The following takes the powder measuring rod 1 configured as shown in Figure 2 as an example to describe the operation process of filling it into the powder filling device as shown in Figure 7 .

[0083] First, the operator holds the operation section 111 on the powder measuring rod 1, inserts the rod body 110 into the first rod receiving chamber 331 of the powder filling device 3 with the letter A consistent with the letter A of the powder measuring rod 1, and in this process, aligns the positioning portion 114 on the powder measuring rod 1 with the first positioning groove 332 on the powder filling device 3 and inserts it to the deepest, at which time, the dose groove 12 on the powder measuring rod 1 is aligned with the feeding port 32 on the powder filling device 3, so as to be ready for the subsequent powder filling operation of the operator.

[0084] In order to realize the recycling of the excess powder after filling and avoid the waste of powder, please refer to Figure 9 , which shows the structure of the tray of the powder filling device in an embodiment of the present application, as shown in the figure, the powder filling device 3 further comprises a tray receiving chamber 34 for inserting a tray 5 to receive the excess powder. Further, the tray receiving chamber 34 can be configured to extend from an opening on the distal end face of the body 31 to the inside of the body 31, the opening is located below the first containing cavity 33 and communicates with the first containing cavity 33. Specifically, for example, a through hole G can be arranged at the bottom of the first containing cavity 33, and the tray receiving chamber 34 is communicated with the first containing cavity 33 through the through hole G, so that when the tray 5 is placed in the tray receiving chamber 34, the powder receiving portion on the tray 5 is just directed to the through hole G, and when the powder measuring rod is taken out after being filled with powder through the feeding port 32, the excess powder can fall into the powder receiving portion of the tray 5 through the through hole G.

[0085] In an embodiment, as shown in Figure 8 The tray receiving chamber 34 comprises a first fool-proof structure 341. For example, the first fool-proof structure 341 can be configured as a recessed area of the lower sidewall of the tray receiving chamber 34, the opening of the recessed area constituting a part of the opening on the tray receiving chamber 34, so that the corresponding part on the tray 5 can be inserted.

[0086] Please continue to refer to Figure 9 The tray 5 comprises a tray body 52, which is inserted through the opening of the tray receiving chamber 34. Further, the tray 5 can also comprise a second fool-proof structure 51, which is adapted to the first fool-proof structure 341. The second fool-proof structure 51 is arranged on the lower side of the tray body 52. In the example shown in Figure 9 The second fool-proof structure 51 is configured as a protruding structure on the bottom of the tray body 52.

[0087] As shown in Figure 9 The second fool-proof structure 51 is adapted to the first fool-proof structure 341, so that the tray 5 can only be inserted into the tray receiving chamber 34 in the correct way, thereby preventing the operator from making installation errors. Specifically, when the operator installs the tray 5 into the tray receiving chamber 34, the protruding structure of the second fool-proof structure 51 on the tray 5 needs to be combined with the recessed area of the first fool-proof structure 341 of the tray receiving chamber 34.

[0088] In other embodiments, the first fool-proof structure 341 and the second fool-proof structure 51 can also be configured as devices capable of emitting sound or light prompts, when the tray 5 is correctly inserted into the tray receiving chamber 34, the first fool-proof structure 341 or the second fool-proof structure 51 can emit light of a certain color or emit a specific sound to indicate the correct operation and improve the operator's perception in operation.

[0089] In an embodiment, as shown in Figure 9 The tray body 52 can further comprise an operation part 521 and a powder receiving part 522. The operator can insert the tray 5 into the tray receiving chamber 34 by gripping or holding the operation part 521, and the operation part 521 protrudes from the tray receiving chamber 34 for the operator to operate when the tray 5 is inserted into the tray receiving chamber 34 through the opening of the tray receiving chamber 34. Of course, the operation part 521 can also not be arranged, and the operator can directly grip on the tray body 52.

[0090] In one embodiment, the powder receiving portion 522 can be configured as a groove away from the operation portion 521 to collect excess powder. Further, the groove is configured on the end face above the tray body 52, and the powder receiving portion 522 is opposite to the powder inlet 32 when the tray 5 is inserted into the tray receiving chamber 34. After the operator inserts the medicine powder measuring rod to fill the medicine powder, and removes the medicine powder measuring rod, more than the preset amount of medicine powder is scraped off from the rod by the first rod receiving chamber 331 due to the size limitation of the first rod receiving chamber 331, and thus enters the powder receiving portion 522 of the tray 5 for reuse.

[0091] In order to fill different medicine powders in different medicine powder measuring rods, the present application discloses a medicine powder filling assembly in some embodiments. Please refer to Figure 10 , which shows a schematic diagram of the medicine powder filling assembly in one embodiment of the present application. As shown in Figure 10 , the filling device assembly includes a first medicine powder filling device 3 and a second medicine powder filling device 4. The first medicine powder filling device 3 is matched with the first medicine powder measuring rod to fill the first medicine powder into the first medicine powder measuring rod; and the second medicine powder filling device 4 is matched with the second medicine powder measuring rod to fill the second medicine powder into the second medicine powder measuring rod. For example, the first medicine powder measuring rod and the second medicine powder measuring rod can be respectively configured as the medicine powder measuring rod as described in any embodiment of Figures 1 to 6 and the related description; and the first medicine powder filling device 3 and the second medicine powder filling device 4 can be respectively configured as the medicine powder filling device as described in any embodiment of Figures 7 to 8 and the related description. More specifically, when the first medicine powder measuring rod is configured as the first medicine powder measuring rod 1 as shown in Figure 5 , the first medicine powder filling device 3 is configured as the first medicine powder filling device 3 as shown in Figure 7 ; when the second medicine powder measuring rod is configured as the second medicine powder measuring rod 2 as shown in Figure 5 , the second medicine powder filling device 4 is configured as the second medicine powder filling device 4 as shown in Figure 10 .

[0092] In order to enable the operator to distinguish which medicine powder needs to be filled into the first medicine powder filling device and the second medicine powder filling device (which can also be understood as distinguishing the medicine powder measuring rods matched with the first medicine powder filling device and the second medicine powder filling device respectively), in one embodiment, the identification structure of the first medicine powder filling device 3 is matched with the identification structure of the first medicine powder measuring rod, and the identification structure of the second medicine powder filling device is matched with the identification structure of the second medicine powder measuring rod. Specifically, in the embodiment in which the identification structure is configured as a letter identification, as shown in Figure 10 and Figure 5As shown, when the letter mark 115 of the first powder measuring rod 1 is configured as letter A, the letter mark 35 of the first powder filling device 3 is also configured as letter A; when the letter mark 215 of the second powder measuring rod 2 is configured as letter B, the letter mark 45 of the second powder filling device 4 is also configured as letter B.

[0093] In an embodiment, the preset angle of the first positioning slot of the first powder filling device with respect to the vertical direction of the feeding port thereof is configured to be opposite to the preset angle of the positioning slot of the second powder filling device with respect to the vertical direction of the feeding port thereof. Figure 10 and Figure 5 In the example shown, the preset angle of the first positioning slot 332 of the first powder filling device 3 with respect to the vertical direction of the feeding port 32 thereof is -60°, so as to be adapted to the first powder measuring rod 1; the preset angle of the positioning slot 432 of the second powder filling device 4 with respect to the vertical direction of the feeding port 42 thereof is 60°, so as to be adapted to the second powder measuring rod 2.

[0094] The operation of filling the second powder into the second powder measuring rod 2 using the second powder filling device 4 is the same as the operation of filling the first powder into the first powder measuring rod 1 using the first powder filling device 3, which will be described in detail below by taking the filling of the first powder as an example. Figure 5 and Figure 10

[0095] When the first powder is filled into the first powder measuring rod 1 using the first powder filling device 3, the operator first holds the operation part 521 of the tray 5, embeds the second fool-proof structure 51 into the first fool-proof structure 341 at the distal end of the first powder filling device 3, so as to complete the installation of the tray 5, at this time, the powder receiving part 522 is inside the first powder filling device 3 and faces the feeding port 32, while the operation part protrudes from the tray receiving chamber 34; then, the operator holds the holding part 113 of the first powder measuring rod 1, embeds the positioning part on the first powder measuring rod 1 into the first positioning slot 332 at the proximal end of the first powder filling device 3, so as to complete the installation of the first powder measuring rod 1, at this time, the dose slot 12 on the first powder measuring rod 1 is aligned with the feeding port 32 on the first powder filling device 3; then, the operator fills the first powder into the feeding port 32 and taps the first powder filling device 3 gently, so that the first powder falls into the bottom of the dose slot 12 and fills the dose slot 12; thereafter, the operator holds the holding part 113 of the first powder measuring rod 1 and pulls the first powder measuring rod 1 out of the first containing cavity 33; finally, the operator holds the operation part of the tray 5 and pulls the tray 5 out of the first powder filling device 3, so as to recover the first powder in the powder receiving part 522.

[0096] ​When the medicine powder is filled into the medicine powder measuring rod, due to the light weight of the particles of the medicine powder itself, the medicine powder is easily affected by the environment, for example, the air flow easily causes the medicine powder to fly, thereby causing the loss of the medicine powder, leading to the inaccurate dosage of the medicine powder in the analysis test, and the impurities in the air can enter the medicine powder, causing the pollution of the medicine powder. In view of this, in some embodiments of the present application, a transfer device is also disclosed, which is suitable for storing or transferring the medicine powder measuring rod, for example, the medicine powder measuring rod described in any of the preceding embodiments. Further, the transfer device is provided with a containing cavity on the base for receiving the medicine powder measuring rod, so that the containing cavity can wrap the dosage groove of the medicine powder measuring rod, avoiding the direct contact of the medicine powder contained in the dosage groove with the air, thereby avoiding the loss and pollution of the medicine powder, and further ensuring the accuracy of the analysis test. In addition, the transfer device is also provided with a frame which can be in a locked state, and the operation section of the medicine powder measuring rod is locked together, so that the medicine powder measuring rod can be stored on the base or transferred with the base, and will not be mistakenly pulled out or fall off, thereby enhancing the safety of storing or transferring the medicine powder measuring rod.

[0097] Please refer to Figure 11 and Figure 12 , Figure 11 shows the structural schematic diagram of the transfer device in an embodiment of the present application, Figure 12 shows the split structural schematic diagram of the transfer device in an embodiment of the present application, Figure 11 is described in the medicine powder measuring rod 1 arranged in the transfer device 6, as shown in Figure 11 and Figure 12 , the transfer device 6 includes a base 61 and a frame 62. The base 61 is provided with a containing cavity 611 for receiving the medicine powder measuring rod, and when the medicine powder measuring rod is inserted into the containing cavity 611, the operation section 111 thereof protrudes from the containing cavity 611 for operation (as shown in Figure 11 It should be noted that in order to distinguish from the containing cavities in the subsequent other devices or components, the containing cavity included in the transfer device is also called a second containing cavity in the embodiment.

[0098] As shown in Figure 11 and Figure 12 , the frame 62 is used to support the base 61 and can move relative to the base 61 to lock the medicine powder measuring rod, and the operation section 111 of the medicine powder measuring rod cannot be operated in the locked state, so that the medicine powder measuring rod is stored on the base 61 or transferred with the base 61. Wherein, the relative movement of the frame 62 to the base 61 means that the relative movement of the base 61 and the frame 62 can be achieved, that is, only the base 61 can be operated to move, only the frame 62 can be operated to move, or the base 61 and the frame 62 can be operated to move.

[0099] In the locked state, the inoperability of the operating section 111 of the powder measuring rod means that the operator cannot remove the powder measuring rod by operating the operating section 111. For example, the frame 62 may block part or all of the operating section 111, making it difficult for the operator to move the operating section 111, or the frame 62 may obstruct the movement path of the operating section 111, so that even if the operator can contact the operating section 111, they cannot move it. In other words, in the locked state, the operating section of the powder measuring rod may or may not be contacted by the operator, as long as the powder measuring rod cannot be pulled out of the second receiving cavity of the transfer device.

[0100] In one embodiment, such as Figure 12 As shown, the base 61 is configured as a generally rectangular parallelepiped structure, and further, it can be elongated, thereby enabling the configuration of multiple second receiving cavities. To avoid injury to operators, in such cases... Figure 12 In the example shown, the edges of the base facing upwards and to the left and right are configured as curved edges or inclined surfaces.

[0101] In one embodiment, the second receiving cavity 611 extends inwardly from the opening on the end face of the front end of the base 61, and the powder measuring rod 1 is inserted into the base 61 through the opening. Figure 12 As shown, the second receiving cavity 611 includes a rod receiving chamber 6111 and a positioning groove 6112. It should be noted that, in order to distinguish it from the rod receiving chamber included in the receiving cavity of other devices or components, in this embodiment, the rod receiving chamber included in the second receiving cavity is also referred to as the second rod receiving chamber. Similarly, the positioning groove further included in the second receiving cavity in subsequent embodiments is also referred to as the second positioning groove, and will not be described again when the positioning groove further included in the second receiving cavity is mentioned later.

[0102] The second rod receiving chamber 6111 is for inserting the powder measuring rod. The second positioning groove 6112 is disposed circumferentially in the second rod receiving chamber 6111 and is used to cooperate with the positioning part of the powder measuring rod to limit the insertion depth of the powder measuring rod.

[0103] In an embodiment, the second positioning groove 6112 is configured to have a preset angle with respect to the vertical direction of the horizontal plane where the base 61 is located, and the preset angle is consistent with the preset angle of the positioning portion of the medicament measuring rod with respect to the vertical direction of the dose groove. That is, the second positioning groove 6112 has a preset angle of -60° or 60° with respect to the vertical direction of the horizontal plane where the base 61 is located. It can be understood that when the preset angle of the axis direction of the positioning portion of the medicament measuring rod with respect to the vertical direction of the dose groove is -60°, the preset angle of the axis direction of the second positioning groove 6112 of the transfer device 6 with respect to the vertical direction of the horizontal plane where the base 61 is located is also -60°; when the preset angle of the axis direction of the positioning portion of the medicament measuring rod with respect to the vertical direction of the dose groove is 60°, the preset angle of the axis direction of the second positioning groove 6112 of the transfer device 6 with respect to the vertical direction of the horizontal plane where the base 61 is located is also 60°, and the vertical direction of the dose groove is the same as the vertical direction of the horizontal plane where the base 61 is located. In this way, when the rod is inserted into the second accommodating cavity 611, the second positioning groove 6112 engages with the positioning portion to play a positioning role on the medicament measuring rod.

[0104] In an embodiment, the depth of the second rod receiving chamber 6111 is less than the length of the rod of the medicament measuring rod, so that when the rod is inserted, the operating section thereof protrudes out of the second rod receiving chamber 6111. In order to ensure that when the rod is inserted into the second accommodating cavity 611, the operating section on the medicament measuring rod protrudes out of the second accommodating cavity 611, the depth of the second positioning groove 6112 can be limited, and in a preferred example, the depth of the second positioning groove 6112 is configured to be 14 mm.

[0105] Specifically, when any one of the medicament measuring rods is inserted, the operator needs to align the positioning portion on the medicament measuring rod with the second positioning groove on the transfer device through the holding portion on the medicament measuring rod and insert it to the deepest, so as to insert the rod of the medicament measuring rod into the second rod receiving chamber of the transfer device.

[0106] In order to realize the storage or transfer of a plurality of first medicament measuring rods, in an embodiment, as shown in Figure 11 and Figure 12 , the second accommodating cavities 611 can be configured to be arranged in parallel. In an implementation, the second accommodating cavities 611 are configured to be 6, 7, 8, 9, 10, 11, 12, 13, 14; preferably, the second accommodating cavities 611 are configured to be 10.

[0107] Further, in order to facilitate the operator to distinguish a plurality of second accommodating cavities, in an embodiment, as shown in Figure 11 and Figure 12As shown, the upper surface of the base 61 is provided with a number mark. Specifically, the 10 second accommodating cavities 611 from left to right are provided with the numbers 1, 2, 3, 4, 5, 6, 7, 8, 9 and 10 in sequence on the upper surface directly above the base 61.

[0108] In order to indicate the type of the transfer device, in an embodiment, an identification structure is arranged on the base of the transfer device. The type of the transfer device refers to different transfer devices, and further, the identification structure on the base can distinguish the types of the powders accommodated in the second accommodating cavities. The identification structure includes but is not limited to visual identification such as color identification, number identification, letter identification, or any combination of the above, and the arrangement of the identification structure on the base includes but is not limited to pasting, carving, labeling, laser engraving and digital display screen, and further, in order to facilitate the observation of the operator, the identification structure can be arranged at the middle position of the upper surface of the base.

[0109] In the embodiment where the identification structure is a letter identification, when the operator needs to distinguish the type of the inserted powder measuring rod and further distinguish the type of the powder accommodated in the second accommodating cavity, the operator can achieve the above purpose by observing the letter, so as to avoid confusion. For example, as shown in Figure 12 As shown, the operator can be indicated by the letter identification A on the upper surface of the base 61 of the transfer device 6 to insert the powder measuring rod with the letter A on the end face, for example, the first powder measuring rod, into the second accommodating cavity 611, and the operator can be indicated by the letter identification B on the upper surface of the base 61 of the transfer device 6 to insert the powder measuring rod with the letter B on the end face, for example, the second powder measuring rod, into the second accommodating cavity 611, so that the operator can distinguish the type of the inserted powder measuring rod in the second accommodating cavity 611, and further distinguish the first powder and the second powder.

[0110] As shown in Figure 12 As shown, the frame 62 further includes a support portion 621 and a blocking portion 622. The support portion 621 is provided with a moving channel 623, and the base 61 is supported in the moving channel 623 and can move relative to the support portion 621 in accordance with the moving channel. The blocking portion 622 is fixedly arranged on the support portion 621, and when the base 61 moves relative to the support portion 621 to the terminal end of the moving channel 623, the blocking portion 622 is located on the operable path of the operation section of the powder measuring rod to block the operation of the operation section.

[0111] In an embodiment, the moving channel 623 is arranged in an inverted L shape, so that the base 61 moves transversely and longitudinally relative to the support portion 621. The following will be described in combination with Figure 13The relative movement of the base 61 to the support part 621 in response to the movement of the moving channel 623 will be described in the following with the example of the (a) to (c) in the figure.

[0112] Please refer to Figure 13 , which shows the process of the movement of the frame relative to the base in an embodiment of the application to lock the powder measuring rods, as shown in Figure 13 The transfer device 6 shown in a is in the initial state, which means that the operator can move the operation section 111 of the powder measuring rod 1 in its operable path, that is, the operator can insert or pull out the 10 powder measuring rods shown in a from the corresponding 10 second accommodating cavities one by one. Of course, the operator does not necessarily insert or pull out the powder measuring rods consistent with the number of second accommodating cavities of the transfer device, but can insert or pull out less or consistent with the number of second accommodating cavities of the transfer device according to the application scenario. Figure 13 The base 61 and the frame 62 in the transfer device 6 shown in b and c can move relative to each other. Specifically, as shown in b, the operator moves the frame 62 forward, so that the base 61 moves relative to the beginning of the horizontal structure in the inverted L-shaped structure of the moving channel 623 to the end of the horizontal structure (that is, the beginning of the vertical structure in the inverted L-shaped structure), and then as shown in c, the operator moves the frame 62 upward, so that the base 61 moves relative to the beginning of the vertical structure in the inverted L-shaped structure to the end of the vertical structure. That is, the base 61 has a relative displacement in the front-rear direction and the up-down direction relative to the frame 62, and at this time, the blocking part 622 on the frame 62 follows the frame and is located on the operable path of the operation section of the powder measuring rod, so as to hinder the operation of the operator on the operation section.

[0113] Figure 13 The base 61 and the frame 62 in the transfer device 6 shown in b and c can move relative to each other. Specifically, as shown in b, the operator moves the frame 62 forward, so that the base 61 moves relative to the beginning of the horizontal structure in the inverted L-shaped structure of the moving channel 623 to the end of the horizontal structure (that is, the beginning of the vertical structure in the inverted L-shaped structure), and then as shown in c, the operator moves the frame 62 upward, so that the base 61 moves relative to the beginning of the vertical structure in the inverted L-shaped structure to the end of the vertical structure. That is, the base 61 has a relative displacement in the front-rear direction and the up-down direction relative to the frame 62, and at this time, the blocking part 622 on the frame 62 follows the frame and is located on the operable path of the operation section of the powder measuring rod, so as to hinder the operation of the operator on the operation section. Figure 13 Figure 13 Further, in order to ensure that the blocking part 622 can be kept in the position of hindering the operability path, as shown in d, the transfer device 6 can be further fixed in the locked state, for example, the operator can keep it in the locked state by operating the frame 62. The structure and process of fixing the transfer device 6 in the locked state will be described later. Figure 13 Further, in order to ensure that the blocking part 622 can be kept in the position of hindering the operability path, as shown in d, the transfer device 6 can be further fixed in the locked state, for example, the operator can keep it in the locked state by operating the frame 62. The structure and process of fixing the transfer device 6 in the locked state will be described later.

[0114] Figure 13 Further, in order to ensure that the blocking part 622 can be kept in the position of hindering the operability path, as shown in d, the transfer device 6 can be further fixed in the locked state, for example, the operator can keep it in the locked state by operating the frame 62. The structure and process of fixing the transfer device 6 in the locked state will be described later.

[0115] ​​​In other embodiments, the moving channel 623 may also be configured in other structural shapes. For example, the moving channel 623 may be configured as a vertical structure so that the base 61 moves longitudinally relative to the support in accordance with the moving channel. In this case, the operator first inserts the powder measuring rod into the second receiving cavity in sequence, and then operates the frame to move it to the end within the vertical structure of the moving channel 623, thereby positioning the blocking part on the operable path of the operating section of the powder measuring rod to prevent the operator from inserting or removing the operating section.

[0116] In one embodiment, such as Figure 12 As shown, the support portion 621 includes a first support frame 6211 and a second support frame 6212 arranged opposite to each other. A moving channel 623 is disposed on the first support frame 6211 and the second support frame 6212. For example, two moving channels 623 may be configured, respectively on opposite side walls of the first support frame 6211 and the second support frame 6212. The base 61 is relatively movable across the first support 6211 and the second support frame 6212 via a connecting portion 6213. Specifically, one connecting portion 6213 can be connected to the base 61 by passing through the moving channel 623 on the first support frame 6211, and another connecting portion 6213 can be connected to the base 61 by passing through the moving channel 623 on the second support frame 6212. In some examples, such as... Figure 12 As shown, the first support frame 6211 and the second support frame 6212 can be configured as a U-shaped plate structure. In some examples, the connecting part 6213 can be, for example, a bolt or screw, and corresponding screw holes are provided on the base 61. Specifically, the size of the nut portion of the connecting part 6213 is larger than the width of the moving channel. When the connecting part is connected to the base, the connecting part interacts with the screw holes on the base, and due to the size limitation of the nut portion, the base is positioned within the moving channel 623 between the first support frame 6211 and the second support frame 6212 and will not fall out of the moving channel.

[0117] In one embodiment, the support portion 621 further includes a reinforcing plate 6214, which is connected between the first support frame 6211 and the second support frame 6212 to increase the strength of the support portion 621. Figure 12 In the example shown, the reinforcing plate 6214 is located at the far end of the transfer device 6, and its shape and size perfectly match the structural surface of the support. Its material includes, but is not limited to, composite materials, metal plates, and glass fiber reinforced polymers. The connection between the reinforcing plate 6214 and the support 621 includes adhesive bonding, bolts, screws, or other mechanical connection methods to ensure a secure and reliable fixation.

[0118] In an embodiment, the blocking part 622 is configured as a flat structure spanning the first support frame 6211 and the second support frame 6212, and cooperates with the movement of the base 61 in the movement channel 623, thereby blocking the operation section of the drug powder measuring rod. Figure 1 and Figure 12 In the example shown, the blocking part 622 is arranged at the proximal end of the transfer device 6. The connection of the blocking part 622 with the first support frame 6211 and the second support frame 6212 includes adhesion, bolts, screws or other mechanical connection methods, to ensure that the fixed method is firm and reliable.

[0119] In an embodiment, the frame 62 further includes a holding part 624, through which the operator operates the frame 62 relative to the base 61. In order to leave a certain operation space for the operator, the holding part 624 is arranged at the top of the frame 62, connecting the top ends of the first support frame and the second support frame, and being a certain distance from the mounting position of the base 61. The connection of the holding part 624 with the first support frame 6211 and the second support frame 6212 includes but is not limited to adhesion connection, welding and mortise and tenon connection.

[0120] In an embodiment, the frame 62 further includes a locking part 625, which is used to lock the blocking part 622 to keep the operation section of the drug powder measuring rod on the operable path. In Figure 12 In the example shown, the holding part 624 is rotatably connected to the support part 621, and the locking part 625 is fixed to the holding part 624, and the operator rotates the holding part 624 to lock the blocking part 622. The locking part 625 is configured as a plate-shaped structure fixed to the holding part 624, and its length is slightly smaller than the distance between the upper surface of the base 61 and the holding part 624 when the operation section of the drug powder measuring rod is locked.

[0121] Please refer to Figure 13 When the locking part 625 is used to change the drug powder measuring rod from the initial state as shown in Figure 13 a to the locked state as shown in Figure 13 d, the operator moves the frame 62 forward relative to the base 61 by operating the holding part 624 of the transfer device 6, so that the base 61 moves laterally relative to the connecting part 6213 on the movement channel 623 to the state as shown in Figure 13 b. Then, the operator operates the holding part 624 to pull the frame upward relative to the base 61, and rotates the holding part 624 in the clockwise direction to make the locking part 625 connected to the holding part 624 vertically above the base 61, at which time the base 61 moves longitudinally relative to the connecting part 6213 on the movement channel 623 to the state as shown in Figure 13The movement state is shown in c. Finally, the operator can operate the grip 624 to lower the frame (or directly release the grip 624 to allow the frame to fall under its own weight). At this time, the locking part 625 contacts the upper surface of the base 61, forming a position as shown in c. Figure 12 The locked state is shown in d.

[0122] In another embodiment, the locking part 625 is used to unlock the blocking part 622 from the operable path of the operating section of the powder measuring rod. Figure 13 In the example shown, the grip 624 is rotatably connected to the support 621, and the locking part 625 is fixed to the grip 624. The operator unlocks the blocking part 622 by rotating the grip 624. Please refer to... Figure 13 When the operator needs to remove the powder measuring rod from the transfer device for testing, the locking part 625 is used to move the powder measuring rod from the transfer device. Figure 13 The locked state shown in d changes to the following: Figure 13 The initial state is shown in figure a. Specifically, the operator needs to rotate the grip 624 counterclockwise to unlock the blocking part 622, and lower the frame 62 so that the blocking part 622 of the transfer device 6 leaves the operable path of the operating section, forming the initial state shown in figure a. Figure 13 The state shown in b. Then, the operator operates the grip 624 to move the frame 62 rearward relative to the base 61, forming the state shown in b. Figure 13 As shown in Figure a, the operator can remove the powder measuring rod at this point.

[0123] The following combination Figure 13 This document details the operations required for storing or transferring the powder measuring rod using the transfer device 6. The operator aligns the positioning part on the powder measuring rod with the second positioning groove 6112 on the transfer device 6 using the grip on the measuring rod and inserts it to its deepest point, thereby inserting the rod into the second rod receiving chamber 6111 of the transfer device 6. The operator completes the insertion of each powder measuring rod in this manner and connects the base 61 to the connecting part 6213 on the frame 62, forming a... Figure 13 The initial state is shown in figure a; then, the operator operates the grip 624 of the transfer device 6 to move the frame 62 forward relative to the base 61, and the connecting part 6213 moves accordingly, forming as shown in figure a. Figure 13 The movement state is shown in b; thereafter, the operator operates the grip 624 to pull the frame 62 upward relative to the base 61, and rotates the grip 624 clockwise so that the locking part 625, which is fixedly connected to the grip 624, is vertically positioned above the base 61, forming as shown in b. Figure 13 The movement state is shown in c; finally, the operator places the transfer device on a horizontal surface, so that the locking part 625 rests on the base 61, forming as shown in c. Figures 1 to 6The locking state shown in d is used to achieve the storage or transfer of the powder measuring rod.

[0124] When the powder measuring rod needs to be taken out from the transfer device for analysis test, the unlocking steps of the powder measuring rod are opposite to the above-mentioned locking steps, which are not described here.

[0125] As mentioned above, when the airflow analysis test needs to be performed on the mixture of two powders, the powder measuring rod assembly including the first powder measuring rod and the second powder measuring rod needs to be set. In order to match this, the first transfer device and the second transfer device are disclosed in some embodiments of the present application to achieve the storage or transfer of the first powder measuring rod and the second powder measuring rod, respectively. For example, the first powder measuring rod and the second powder measuring rod can be respectively configured as the powder measuring rod as described in any one of the embodiments of the powder measuring rod and the related description; the first transfer device and the second transfer device can be respectively configured as the transfer device as described in any one of the embodiments of the transfer device and the related description. Figures 11 to 13 Figure 14

[0126] In order to enable the operator to distinguish which powder measuring rod is contained in the first transfer device and the second transfer device, and further distinguish which powder is stored or transferred, in an embodiment, the identification structure of the first transfer device matches the identification structure of the first measuring rod, and the identification structure of the second transfer device matches the identification structure of the second measuring rod. Specifically, in the embodiment in which the identification structure is configured as a letter identification, when the letter identification of the first powder measuring rod is letter A, the letter identification of the first transfer device is also letter A; when the letter identification of the second powder measuring rod is letter B, the letter identification of the second transfer device is also letter B, so that the operator can distinguish the first powder and the second powder in the transfer device according to letter A and letter B.

[0127] In an embodiment, the preset angle of the positioning groove of the first transfer device compared to the vertical direction of the horizontal plane is configured to be opposite to the preset angle of the positioning groove of the second transfer device compared to the vertical direction of the horizontal plane. For example, when the preset angle of the positioning groove of the first transfer device compared to the vertical direction of the horizontal plane is -60°, the preset angle of the axis direction of the positioning part of the corresponding first powder measuring rod compared to the vertical direction of the dose groove is also -60°; when the preset angle of the positioning groove of the second transfer device compared to the vertical direction of the horizontal plane is 60°, the preset angle of the axis direction of the positioning part of the corresponding second powder measuring rod compared to the vertical direction of the dose groove is also 60°.

[0128] ​​In order to cooperate with the powder measuring rod to dispense powder and form an airflow, for example, to perform airflow analysis tests on the preset amount of powder contained in the dosage slot of the powder measuring rod in any of the foregoing embodiments, this application also discloses a simulated inhalation device in some embodiments. By setting a manifold on the main body, the distribution and guidance of airflow are realized; by setting a receiving cavity on the main body, the powder measuring rod can be placed in the receiving cavity and the dosage slot is connected to the chamber inlet of the manifold, thereby forming an airflow carrying powder.

[0129] Please see Figure 14 The figure shows a schematic diagram of a simulated inhalation device in one embodiment of this application. As shown, the simulated inhalation device 8 includes a main body 81 and a receiving cavity 82. A manifold is disposed on the main body 81. Figure 14 (Not shown in the diagram), the manifold is used to split and guide the airflow. The receiving cavity 82 is disposed on the main body 81 to receive the powder measuring rod. The receiving cavity 82 is connected to the manifold such that when the powder measuring rod is engaged with the receiving cavity, the dosage slot of the powder measuring rod is connected to the manifold, thereby allowing the airflow to carry the powder in the dosage slot and be dispensed through the manifold. It should be noted that, in order to distinguish it from the receiving cavities in other devices or components, in this embodiment, the receiving cavity included in the simulated inhalation device is also referred to as the third receiving cavity.

[0130] In one embodiment, such as Figure 14 As shown, the main body 81 is configured as a generally rectangular box-shaped structure. To avoid bumping into operators, in... Figure 15 In the example shown, the edges of the main body 81 facing each direction are configured as curved edges or edges of inclined surfaces.

[0131] Please see Figure 14 and combined Figure 15 ,in, Figure 14 The diagram shown is a cross-sectional schematic of a manifold disposed in the main body in one embodiment of this application. (See Figure 15 and...) Figure 14 As shown, a distribution cavity 83 is provided on the main body 81, and the manifold 9 is disposed in the distribution cavity 83. The distribution cavity 83 can be configured as a groove that is opened in the middle region of the main body 81 and has an opening facing the top surface of the main body 81 and an opening facing the side surface of the main body 81, and its shape is adapted to the manifold to allow the manifold to enter.

[0132] In an embodiment, the distribution cavity 83 has an air inlet for the air flow to enter the manifold 9, which can be an opening on the side of the distribution cavity 83 facing the body portion 81, for example. A positioning mechanism 84 is arranged on the air inlet to retain the manifold 9 in the distribution cavity, which is arranged on the end face of one side of the body portion 81 and has an air inlet structure corresponding to the air inlet so that the air flow can enter the air inlet. Figure 14 In the example shown, the air inlet structure is configured as a grid 841 arranged on the positioning mechanism 84. The grid structure helps to achieve uniform air flow distribution on the one hand, so that an uneven flow field can be avoided near the air inlet, ensuring that each area can be subjected to relatively uniform air flow. On the other hand, it helps to prevent pollutants in the air from entering the simulated inhalation device with the air flow for testing, thereby ensuring the accuracy of the test results. In another example, the air inlet structure can be configured as a perforated plate structure arranged on the positioning mechanism, i.e. a plurality of uniformly distributed small holes are arranged on the positioning mechanism so that uniform air flow is generated when the air flow passes through the perforated plate structure.

[0133] In an embodiment, as shown in Figure 14 The positioning mechanism 84 includes a positioning plate 842 and a fixing mechanism 843, and the positioning plate 842 is detachably arranged to cover the air inlet through the fixing mechanism 843. It should be understood that when the positioning plate 842 is fixedly arranged to cover the air inlet, the manifold can be fixedly installed in the body portion 81; when the positioning plate 842 is detached from the air inlet, the manifold can be detached from the body portion 81, so that cleaning after testing can be performed.

[0134] In an embodiment, as shown in Figure 14 The positioning plate 842 is provided with a first coupling portion 8421, and the fixing mechanism 843 is connected to the body portion 81 and is provided with a second coupling portion 8431, and the fixing mechanism 843 is rotated to make the second coupling portion 8431 engage or release the first coupling portion 8421. It should be understood that the engagement means that the second coupling portion 8431 and the first coupling portion 8421 are locked relative to each other and cannot move relative to each other, and the release means that the second coupling portion 8431 releases the locking of the first coupling portion 8421 so that it can be detached from the body portion.

[0135] The fixing mechanism includes at least one fixing member, which is configured as an eccentric bolt screwed on the body portion 81, and at this time, the second coupling portion 8431 is configured as the head of the eccentric bolt. The eccentric bolt includes a head and a rod portion. In an embodiment, the rod portion is arranged at a position deviating from the center of the head; in another embodiment, the head is configured as a circular shape including a straight edge, and the rod portion is connected to the body portion 81. Specifically, as shown in Figures 14 to 17As shown, the first engaging portion 8421 is configured as a groove on the two side edges of the positioning plate 842. The groove cooperates with the head of the eccentric bolt to complete the installation and removal of the positioning plate 842 at the air inlet. Specifically, when the straight edge of the head of the eccentric bolt is rotated to the position of the groove of the first engaging portion and is parallel to the groove, the positioning plate 842 can be removed from the air inlet; when the straight edge of the head of the eccentric bolt is away from the position of the groove of the first engaging portion, the positioning plate 842 is fixed to the main body of the simulated inhalation device.

[0136] Please refer to Figure 16 , wherein, Figure 17 is a schematic view showing the release of the fixing mechanism and the positioning plate of the simulated inhalation device in an embodiment of the present application, Figure 14 is a schematic view showing the engagement of the fixing mechanism and the positioning plate of the simulated inhalation device in an embodiment of the present application. After the installation of the manifold 9 in the distribution cavity 83 is completed, the simulated inhalation device is changed from the state shown in Figure 15 to the state shown in Figure 14 . Then, the operator needs to install the positioning plate 842 shown in Figure 16 to shield the air inlet, and the straight edge of the head of the eccentric bolt is directed in the vertical direction towards the third accommodating cavity. At this time, the positioning plate 842 is installed at the position of the air inlet, forming a state as shown in Figure 17 . Then the operator operates the eccentric bolt until the straight edge of the head of the eccentric bolt is away from the position of the groove on the positioning plate, forming a state as shown in Figure 16 . When the positioning plate 842 is removed after the test is completed, the operator only needs to operate the eccentric bolt so that the straight edge of the head of the eccentric bolt is again directed in the vertical direction towards the distribution cavity, forming a state as shown in Figure 15 .

[0137] In an embodiment, the manifold can guide the flow direction of the airflow, so that the drug powder can be pulverized into uniform particles when carried by the airflow, which helps to improve the accuracy of the airflow analysis test. In another embodiment, the manifold can divide the airflow into multiple branches, so that the airflow in each branch flows in multiple different specific directions to ensure uniform distribution of the airflow in the test area, thereby improving the reliability of the test results.

[0138] Please continue to refer to Figure 14 in combination with Figure 18, the manifold 9 includes a chamber 91 having a chamber inlet 911 and a chamber outlet 912, at which point air flow can enter the chamber inlet 911 of the manifold 9 through the air inlet of the dispensing chamber 83, and be directed from the chamber inlet 911 to the chamber outlet 912. Further, the manifold 9 includes a vent passage (not shown) having a vent passage outlet in communication with the chamber inlet 911 and a vent passage inlet, at which point air flow can enter the vent passage inlet of the manifold 9 through the air inlet of the dispensing chamber 83, and be directed from the vent passage outlet to the chamber inlet 911 to the chamber outlet 912.

[0139] In one embodiment, the third receiving chamber 82 is in communication with the dispensing chamber 83, and the third receiving chamber 82 enables communication with the manifold 9 when the manifold 9 is disposed in the dispensing chamber 83. Please refer to Figure 18 , which shows a cross-sectional view of the inhaler device without the manifold in one embodiment of the present application, as Figure 15 shown, the third receiving chamber 82 and the dispensing chamber 83 are formed in the main body portion 81 and are in communication through a through opening 85, and the chamber inlet of the manifold 9 is oriented towards the through opening 85 when the manifold 9 is disposed in the dispensing chamber 83.

[0140] Please continue to refer to Figure 14 and in conjunction with Figure 14 , as Figure 15 and Figure 19 shown, when the medicament measuring rod is inserted into the third receiving chamber 82, the dose well of the medicament measuring rod is oriented towards the through opening 85 and is opposite to the chamber inlet, so that air flow entering from the vent passage inlet is carried into the dose well through the vent passage outlet to the chamber inlet, and is directed to the chamber outlet.

[0141] In one embodiment, the chamber inlet and the vent passage outlet are arranged side by side to form an air flow passage. When the rod of the medicament measuring rod is docked with the inhaler device, the opening of the dose well is oriented towards the air flow passage, so that air flow passes from the vent passage outlet through the dose well to the chamber inlet, and is directed from the chamber inlet to the chamber outlet to complete the test. When the air flow analysis test is performed, the inhaler device is connected with an interface to simulate inhalation, and a negative pressure is generated in the manifold, so that air enters the inhaler device from the air inlet, and is sucked from the vent passage inlet of the manifold and passes through the vent passage outlet. Since the opening of the dose well of the medicament measuring rod is oriented towards the vent passage outlet and the chamber inlet, air enters the dose well at the vent passage outlet to carry the medicament, form air flow with uniform medicament particles, and enter the chamber inlet of the manifold, and then exit from the chamber outlet of the manifold.

[0142] In one embodiment, the third receiving chamber is used to receive the medicament measuring rod. Please refer to Figure 19, which shows a schematic structural view of the inhalation device in another perspective in an embodiment of the present application. As shown in Figure 14 The third accommodating cavity comprises a rod receiving chamber 821 for insertion of the rod of the powder measuring rod. In an example, the rod receiving chamber 821 is configured as a hole structure through the main body 81 in front and back directions, which can close the back part of the hole structure when the positioning plate 842 as shown in Figure 19 is installed on the main body 81, and has a positioning effect on the powder measuring rod to some extent. It should be noted that in order to distinguish the rod receiving chamber comprised by the accommodating cavity in other devices or components, the rod receiving chamber comprised by the third accommodating cavity is also referred to as the third rod receiving chamber in the embodiment, and the subsequent description of the rod receiving chamber further comprised by the third accommodating cavity will not be repeated.

[0143] In an embodiment, the third rod receiving chamber 821 has a size suitable for fitting the rod, so that the third rod receiving chamber 821 closes the dose slot when the third accommodating cavity 82 is inserted, thereby preventing external air, impurities or moisture from interfering with the powder. This helps to maintain the consistency of the test environment, thereby reducing the influence of interference factors on the test results.

[0144] In an embodiment, as shown in Figure 20 , the third accommodating cavity further comprises a groove structure 822 formed circumferentially around the third rod receiving chamber 821, which is used to cooperate with the positioning part of the powder measuring rod to make the powder measuring rod interface with the third accommodating cavity 82 in a movement track conforming to the groove structure 822.

[0145] In an embodiment, please refer to Figure 19 and in combination with Figure 20 , wherein, Figure 19 , which shows a cross-sectional view of the inhalation device in an embodiment of the present application, as shown in Figure 20 and Figure 20As shown, the groove structure 822 includes a first groove 8221 and a second groove 8222. The first groove 8221 extends axially on the inner wall of the third receiving cavity 82, i.e. extends in the length direction of the third receiving cavity 82. The second groove 8222 is in communication with the first groove 8221 and is configured to continue extending on the circumference of the third receiving cavity 82 from the first groove 8221, i.e. extends in the circumferential direction of the third receiving cavity 82 and is in communication with the first groove 8221. The powder measuring rod is operated such that the positioning portion is converted from axial movement in the first groove 8221 to circumferential rotation in the second groove 8222 to complete the docking. Specifically, during docking, the operator holds the operation section of the powder measuring rod to insert the rod into the third rod receiving chamber 821, and in the process of insertion, the positioning portion of the powder measuring rod moves linearly in the first groove 8221. In order to make the opening of the dose groove on the powder measuring rod face the air passage outlet and the chamber inlet, the operator needs to hold the operation section to rotate the rod, and in the process, the positioning portion of the powder measuring rod moves rotationally in the second groove 8222.

[0146] In an embodiment, the third receiving cavity 82 can be configured as two to receive two powder measuring rods, and the airflow carrying and mixing the powders in the dose grooves of the two powder measuring rods is guided by the chamber inlet to the chamber outlet. In an implementation, the two third receiving cavities are configured in a mirror-symmetrical manner on both sides of the manifold to respectively communicate with the corresponding chamber inlets. For the sake of distinction, the two third receiving cavities are respectively referred to as third receiving cavity a and third receiving cavity b, and the two powder measuring rods are respectively referred to as powder measuring rod a and powder measuring rod b. As shown, Figures 1 to 6 As shown, the main body 81 is configured with two mirror-symmetrical third receiving cavities, namely third receiving cavity a and third receiving cavity b, the third receiving cavity a is used to receive the powder measuring rod a, and the third receiving cavity b is used to receive the powder measuring rod b. When the manifold 9 is installed in the distribution cavity, it is located exactly in the middle position of the third receiving cavity a and the third receiving cavity b. When the airflow analysis test is performed, the airflow flowing from the air passage inlet to the air passage outlet of the manifold is evenly divided into two streams, which respectively carry the powders in the dose grooves of the powder measuring rod a and the powder measuring rod b, and then simultaneously enter the chamber inlet of the manifold for mixing, and the mixed airflow is guided by the chamber inlet to the chamber outlet.

[0147] In order to facilitate the operator to distinguish the two third accommodating cavities, in an embodiment, the third accommodating cavities are provided with identification structures on the periphery thereof, which are used to indicate the type of the two medicine powder measuring rods received by the two third accommodating cavities, thereby indicating the type of the medicine powder contained in the dose groove of the two medicine powder measuring rods. The identification structures include but are not limited to color identification, number identification, letter identification, or visual identification of any combination of the above, and the identification structures are configured on the periphery of the third accommodating cavities in a manner including but not limited to pasting, carving, labeling, laser engraving, and digital display screen. Further, in order to facilitate the operator to observe, the identification structures can be configured on the end face of the proximal end of the main body, and above the third accommodating cavity corresponding to a certain medicine powder measuring rod.

[0148] In an embodiment where the identification structure is configured as a letter identification, the corresponding letter of the letter identification can be used to indicate the type of the received medicine powder measuring rod. When the types of the medicine powders used for analysis test are different or the medicine powders in different medicine powder measuring rods need to be mixed in the analysis test, the letter can be used to visually indicate the operator, and the operator can determine the type of the received medicine powder measuring rod by observing the letter, thereby determining which type of medicine powder is contained in the medicine powder measuring rod, so as to avoid confusion. For example, the letter identification A on the end face of the proximal end of the main body can be used to indicate that the first medicine powder measuring rod is received, and the dose groove contains a preset amount of the first medicine powder. If the letter identification B on the end face of the proximal end of the main body is used to indicate that the second medicine powder measuring rod is received, and the dose groove contains a preset amount of the second medicine powder, the letter identification A and the letter identification B can be arranged side by side.

[0149] When the third accommodating cavities can be configured as two mirror-symmetrical ones to be connected with the two medicine powder measuring rods, taking the first medicine powder measuring rod inserted into the third accommodating cavity a and the second medicine powder measuring rod inserted into the third accommodating cavity b as an example, wherein the first medicine powder measuring rod and the second medicine powder measuring rod can be respectively configured as the medicine powder measuring rods as described in any embodiment of the present application and the related description, for example, respectively configured as the first medicine powder measuring rod 1 and the second medicine powder measuring rod 2 as shown in Figure 5 and the related description. Figure 21 Please refer to Figure 20 and combine with Figure 21 , wherein, Figure 21 shows a schematic diagram of the process of simulating the connection between the inhalation device and the medicine powder measuring rod in an embodiment of the present application. As shown in Figure 21 , the operator inserts the first medicine powder measuring rod 1 into the third accommodating cavity corresponding to the letter identification A by the letter identification, and in the insertion, specifically, the operation section holding the first medicine powder measuring rod 1 aligns the positioning part of the first medicine powder measuring rod 1 with the groove structure of the third accommodating cavity of the letter identification A, thereby inserting the first medicine powder measuring rod 1 into the third accommodating cavity of the letter identification A, forming as shown in Figure 21the state shown in FIG. 1 b, the opening direction of the dose slot of the first medicament measuring rod 1 is vertical, and the preset angle between the letter mark A on the proximal end face and the vertical direction of the dose slot is 45°.

[0150] When the docking of the first medicament measuring rod 1 is completed, the operator needs to complete the docking of the second medicament measuring rod 2 next. In the example shown in FIG. 1 e, the second medicament measuring rod 2 is longer than the first medicament measuring rod 1, so that the operator can avoid the conflict with the first medicament measuring rod 1 when completing the docking operation as shown in FIG. 1 f. Please continue to refer to FIG. 1 g. Figure 21 Figure 21 , the operator inserts the second medicament measuring rod 2 into the third accommodating cavity corresponding to the letter mark B through the letter mark. Specifically, the operator first holds the operation section of the second medicament measuring rod 2 to align the positioning part of the second medicament measuring rod with the slot structure of the third accommodating cavity of the letter mark B, so as to insert the second medicament measuring rod 2 into the third accommodating cavity of the letter mark B, forming the state shown in FIG. 1 g. Figure 21 c, the opening direction of the dose slot of the second medicament measuring rod 2 is vertical, and the preset angle between the letter mark B on the proximal end face and the vertical direction of the dose slot is -45°.

Figure 21 c, the opening direction of the dose slot of the second medicament measuring rod 2 is vertical, and the preset angle between the letter mark B on the proximal end face and the vertical direction of the dose slot is -45°. Then, the operator holds the operation section of the second medicament measuring rod 2 to rotate the second medicament measuring rod 2 clockwise by 45° (as shown by the arrow in FIG. 1 d), until the letter mark B on the proximal end face of the second medicament measuring rod 2 is in the vertical direction to complete the docking of the second medicament measuring rod 2, forming the state shown in FIG. 1 e. Figure 21 c, the opening direction of the dose slot of the second medicament measuring rod 2 is vertical, and the preset angle between the letter mark B on the proximal end face and the vertical direction of the dose slot is -45°. Then, the operator holds the operation section of the second medicament measuring rod 2 to rotate the second medicament measuring rod 2 clockwise by 45° (as shown by the arrow in FIG. 1 d), until the letter mark B on the proximal end face of the second medicament measuring rod 2 is in the vertical direction to complete the docking of the second medicament measuring rod 2, forming the state shown in FIG. 1 e. Figures 14 to 21 c, the opening direction of the dose slot of the second medicament measuring rod 2 is vertical, and the preset angle between the letter mark B on the proximal end face and the vertical direction of the dose slot is -45°.

[0151] When the docking of the first medicament measuring rod 1 and the second medicament measuring rod 2 is completed, the operator connects the simulation inhalation device to an interface to simulate the process of inhaling, so as to generate a negative pressure in the simulation inhalation device, so that air enters from the air inlet, is then sucked into the air passage inlet of the manifold, and passes through the air passage outlet of the manifold, respectively carrying the first medicament and the second medicament in the dose slot of the first medicament measuring rod 1 and the dose slot of the second medicament measuring rod 2, mixes the first medicament and the second medicament to form an airflow with uniform medicament particles, and then enters the chamber inlet of the manifold, and finally exits from the chamber outlet of the manifold.
