Description

Technical Field

[0001] This application relates to the technical field of dry powder inhalation, and particularly to a visualization detection system for powder aerosol drug inhalation. Background Art

[0002] Respiratory diseases are common diseases. With the deterioration of air quality, the incidence of respiratory diseases is increasing, especially chronic respiratory diseases, which bring relatively high pain indices to patients. At present, the main and most effective ways to treat chronic respiratory diseases in hospitals are metered-dose inhalers, dry powder inhalers, and nebulizers; dry powder inhalers are also called powder aerosols. The corresponding powder aerosol drug inhaler is a tool for supplying powder aerosol drugs and supplying powder aerosol drugs to users in an inhaled manner.

[0003] Existing powder aerosol drug inhalers generally include a medicine box, a mouth suction tube, and a capsule-breaking component. A medicine cavity for placing a medicine capsule is provided in the medicine box. The mouth suction tube is communicated with the medicine cavity. The capsule-breaking component is used to puncture the medicine capsule, and the medicine capsule contains powder aerosol drugs; in actual use, the medicine box is opened, the medicine capsule is placed in the medicine cavity, and then after closing the medicine box, the capsule-breaking component is used to puncture the capsule shell covering the surface of the medicine capsule. Then the user holds the mouth of the mouth suction tube and inhales, so that the powder aerosol drugs in the medicine cavity are inhaled into the user's respiratory tract through the mouth suction tube.

[0004] In view of the above related technologies, during the process of the user inhaling powder aerosol drugs using a powder aerosol drug inhaler, it is inconvenient to clearly know whether the powder aerosol drugs in the medicine cavity have been fully sucked out, and it is easy to occur that the dose of the powder aerosol drugs not fully inhaled by the user is insufficient, which affects the treatment effect. Therefore, it needs to be improved. Summary of the Invention

[0005] In order to facilitate the user to know the inhalation situation of powder aerosol drugs in real time and reduce the situation that the insufficient dose of the powder aerosol drugs not fully inhaled by the user affects the treatment effect, this application provides a visualization detection system for powder aerosol drug inhalation.

[0006] This application provides a visualization detection system for powder aerosol drug inhalation, including a medicine box and a mouth suction tube. A medicine cavity is provided in the medicine box. The mouth suction tube is inserted into the side wall of the medicine box and used to communicate with the medicine cavity; it further includes a concentration detection module, a control module, and a visualization module. Both the concentration detection module and the visualization module are communicatively connected to the control module. The concentration detection module is used to detect the concentration information of the powder aerosol drugs in the mouth suction tube, and the control module is used to control the visualization module to feedback the powder aerosol drug concentration information to the user, so that the user can know the powder aerosol drug concentration information.

[0007] By adopting the above technical solution, the concentration detection module is used to detect the concentration of the powder aerosol medicine, and the visualization module is used to output and feedback the concentration information to the user, so that the user can more clearly and intuitively know whether the powder aerosol medicine has been fully inhaled based on the concentration information feedback by the visualization module, thereby reducing the situation that the insufficient dose of the powder aerosol medicine not fully inhaled by the user affects the treatment effect.

[0008] Preferably, the control module is also communicatively connected to a flow rate detection module, the flow rate detection module is used to detect the gas flow rate information in the mouth suction tube, and the control module is also used to predict the remaining amount of the medicine based on the gas flow rate information and the powder aerosol medicine concentration information, and control the visualization module to feedback the remaining amount of the medicine to the user, so that the user can know the remaining amount of the medicine.

[0009] By adopting the above technical solution, the amount of the powder aerosol medicine at the output mouth suction tube is calculated by detecting the gas flow rate information at the mouth suction tube and the detected powder aerosol medicine concentration information. Since the amount of the powder aerosol medicine stored in a single medicine capsule is known, the remaining amount of the medicine can be determined, and then the remaining amount of the medicine is feedback through the visualization module, so that the user can further intuitively and clearly know whether the powder aerosol medicine has been fully inhaled.

[0010] Preferably, an air flow booster for communicating with the medicine cavity is further connected to the medicine box, and the air flow booster is used to convey oxygen into the medicine cavity when starting; the air flow booster is controlled by the control module; the control module is used to control the visualization module to feedback startup recommendation information to the user when preset conditions are met, so that the user can choose whether to start the air flow booster; the control module is also used to control the opening and closing of the air flow booster according to the startup feedback information when receiving the startup feedback information triggered by the user; wherein the preset conditions at least include that the gas flow rate information is lower than a preset flow rate threshold, and the remaining amount of the medicine is not lower than a preset remaining amount threshold.

[0011] By adopting the above technical solution, when the detected gas flow rate information is lower than the preset flow rate threshold and the remaining amount of the medicine is not lower than the preset remaining amount threshold, it can be considered that the current user has difficulty breathing and causes insufficient suction. At this time, startup recommendation information can be feedback to the user for the user to choose whether to start the air flow booster. When the air flow booster starts, oxygen can be conveyed into the medicine cavity, and in this way, the powder aerosol medicine is conveyed to the user by means of oxygen to achieve the sufficient inhalation degree of the powder aerosol medicine by the user.

[0012] Preferably, a valve for opening and closing the communication position between the mouth straw and the medicine cavity is provided on the mouth straw, and the control module is further used to determine the user's inhalation period and exhalation period based on the change of the gas flow information over time; the control module is used to control the visualization module to feedback the start recommendation information to the user when the preset conditions are met and the user is currently in the inhalation period, so that the user can choose whether to start the airflow booster; the control module is also used to close the valve and start the airflow booster when the user is currently in the exhalation period and the gas flow information is lower than the specified flow.

[0013] By adopting the above technical solution, when the user uses the inhaled powder mist medicine, due to the difference in lung capacity of different users, if the user cannot inhale all the powder mist medicine in one inhalation process, then it is necessary to inhale it in multiple times, and a period of time needs to be reserved for the user to temporarily exhale. Therefore, if it is desired to feedback the startup recommendation information to the user, the feedback is generally provided during the user's inhalation period. If the corresponding gas flow rate is lower than the specified flow rate during the user's exhalation period, the valve is closed and the airflow booster is automatically started to use the oxygen supplied by the airflow booster to clear the mouthpiece straw and the medicine cavity, thereby reducing the agglomeration of the powder mist medicine caused by moisture entering the mouthpiece tank and the medicine cavity.

[0014] Preferably, it also includes a docking ring plate, a medicine supply box and a powder outlet assembly, wherein the lower end of the medicine supply box is open, the docking ring plate covers the open lower end of the medicine supply box, the medicine supply box is rotatably connected to the medicine box, a plurality of medicine capsules are arranged in the medicine supply box along the circumference of the medicine supply box and are located on the upper surface of the docking ring plate, a partition is provided inside the medicine supply box and between two adjacent medicine capsules, a medicine drop port is provided on the surface of the docking ring plate and directly above the medicine cavity; the powder outlet assembly is arranged in the medicine box and is used to puncture the medicine capsule to allow the powder mist medicine to be discharged from the medicine capsule.

[0015] By adopting the above technical solution, the medicine supply box is rotated so that the partition will push the medicine bag to move along the circumferential direction of the medicine supply box during the rotation of the medicine supply box. During this process, the medicine bag is received by the docking ring plate until the medicine bag is pushed to the medicine drop port. The medicine bag falls into the medicine cavity through the medicine drop port under the action of its own weight, and then the powder discharge component is used to pierce the medicine bag, thereby finally realizing convenient supply of the medicine bag and convenient powder discharge.

[0016] Preferably, the powder outlet assembly comprises at least a driving member and two needles, wherein the two needles are arranged on both sides of the medicine cavity, and the driving member is used to drive the needles to move toward or away from the medicine cavity, and to penetrate the medicine cavity when the needles are close to the medicine cavity.

[0017] By adopting the above technical solution, the driving member is used to drive the lancet to move towards the direction close to the medicine cavity and penetrate the medicine cavity. Since the medicine capsule is in the medicine cavity, the medicine capsule in the medicine cavity can be punctured by the lancet, so that the powder medicine can be discharged from the medicine capsule to achieve powder output.

[0018] Preferably, the adjacent partition plates and the side wall of the medicine box together enclose a storage area, the storage area includes a first area and a second area, the first area is used to place a single medicine capsule, the second area is provided with a docking block, and the first area and the second area are arranged alternately at intervals;

[0019] The driving member includes a plurality of transmission sub-members, and the transmission sub-members and the lancets are arranged in one-to-one correspondence. Each transmission sub-member includes a transmission rack, a first torsion spring, and two transmission gears rotatably connected coaxially in the medicine box. The first torsion spring is sleeved on the rotation center where the transmission gear is rotatably connected to the medicine box, and the first torsion spring is connected between the rotation center and the inner wall of the medicine box; one of the transmission gears meshes with the transmission rack, and the transmission rack is connected to the corresponding lancet, and the other transmission gear is rotatably connected to the position of the medicine box close to the medicine dropping port and is located on the rotation path of the docking block when the medicine supply box rotates, and a first tooth groove for meshing with the transmission gear is provided on the side wall of each docking block.

[0020] By adopting the above technical solution, since the first area and the second area are arranged alternately, when the medicine capsule in the first area falls into the medicine cavity through the medicine dropping port, if the medicine box is rotated continuously at this time, the docking blocks in the two second areas adjacent to the first area will be respectively meshed with a transmission gear during the rotation of the medicine supply box, so that the transmission gear rotates self during the movement of the docking block in the second area, thereby driving the lancet to penetrate the medicine cavity. When the lancet completely penetrates the medicine cavity, the docking block in one of the second areas adjacent to the first area just moves above the medicine dropping port. At this time, the docking blocks in the two second areas are both disengaged from the meshing with the transmission gear, and the rotating gear will be driven by the first torsion spring to reverse and reset, thereby driving the lancet to move and reset in the direction away from the medicine cavity.

[0021] Preferably, the driving member also includes a turntable, a second torsion spring, a docking protrusion, a plurality of levers and a second spring, the turntable is rotatably connected to the medicine box through the second torsion spring, and a limit plate is provided on the surface of the turntable, and the turntable and the limit plate together enclose a medicine cavity; an extension block is provided at the edge of the turntable, the lever is slidably connected to the medicine supply box through the second spring, and the lever, the second spring and the docking block are arranged in a one-to-one correspondence; the docking protrusion is arranged at a position of the medicine box close to the blanking port, and when the second spring is not deformed, the docking protrusion is located on the moving path of the lever when it rotates with the medicine supply box; the docking protrusion is used to resist the lever so that the lever moves up relative to the medicine supply box, and the extension block is located on the moving path of the lever after the upward movement when it rotates with the medicine supply box; the side wall of the limit plate is provided with a clearance hole for the needle to pass through.

[0022] By adopting the above technical solution, when the puncture needle penetrates the medicine cavity and punctures the medicine capsule in a straight line direction, the extension block and the turntable are driven to rotate with the rotation of the medicine supply box by means of the lever, so that the medicine capsule rotates relative to the puncture needle, and then the puncture needle can expand the puncture area and rupture degree of the medicine capsule shell during the rotation of the medicine capsule, thereby improving the puncture and rupture effect and accelerating the discharge speed of the powder mist medicine from the medicine capsule.

[0023] Preferably, a plurality of protrusions are provided on the surface of the docking ring plate facing the medicine supply box, and a first spring is commonly connected between each of the protrusions and the docking ring plate. The protrusions are located on the rotation path when the docking block rotates with the medicine supply box, and the side wall of the docking block is provided with a yield surface for pushing against the protrusions and passing over the protrusions during movement.

[0024] By adopting the above technical solution, the protrusion is used to block the docking block to achieve the rotation locking of the medicine supply box. When the medicine supply box is forced to rotate by external force, the docking block will press the protrusion under the action of the yielding surface to make the first spring contract, thereby allowing the docking block to smoothly cross the protrusion and realize rotation. When rotation is not required, the elastic force of the first spring is used to achieve the blocking of the protrusion from the docking block.

[0025] Preferably, the mouth suction tube is slidably connected in the medicine box, a clamping block is provided on the side wall of the mouth suction tube, and a clamping groove for inserting the clamping block is opened on the inner wall of the medicine box. When the clamping block is inserted in the clamping groove, the lower end of the mouth suction tube abuts against the bottom wall of the medicine box and covers the periphery of the medicine cavity, so that the medicine cavity is connected with the mouth suction tube.

[0026] By adopting the above technical solution, when it is necessary to inhale the powder mist medicine, the mouth straw is pressed down so that the mouth straw slides relative to the medicine box and abuts against the bottom wall of the medicine box, and is covered on the periphery of the medicine cavity so that the medicine cavity is only connected to the mouth straw, so that when the user inhales the powder mist medicine with the help of the mouth straw, the powder mist medicine can only directly enter the user's respiratory tract through the mouth straw, and is not easy to disperse to other spaces inside the medicine box.

[0027] In summary, the present application includes at least one of the following beneficial technical effects:

[0028] The concentration detection module is used to detect the concentration of the powder aerosol medicine, and the visualization module is used to output and feedback the concentration information to the user, so that the user can more clearly and intuitively know whether the powder aerosol medicine has been fully inhaled based on the concentration information feedback by the visualization module, thereby reducing the situation that the insufficient dose of the powder aerosol medicine not fully inhaled by the user affects the treatment effect.

[0029] The powder aerosol dose at the output straw is calculated by detecting the gas flow information at the detection port straw and the detected concentration information of the powder aerosol medicine. Since the dose of the powder aerosol medicine stored in a single medicine capsule is known, the remaining amount of the medicine can be determined, and then the remaining amount of the medicine is feedback through the visualization module, so that the user can further intuitively and clearly know whether the powder aerosol medicine has been fully inhaled.

[0038] The following is combined with Figure 1-7 This application is described in further detail.

[0039] The present application embodiment discloses a visual powder mist medicine inhalation detection system. Figure 1 , Figure 2 and Figure 3 The visual powder mist medicine inhalation detection system includes a medicine box 1 and a mouth suction tube 3. The medicine box 1 is provided with a medicine cavity 11. The mouth suction tube 3 is inserted at the top of the medicine box 1 and communicates with the medicine cavity 11. The mouth suction tube 3 is provided with a valve for controlling whether the medicine box 1 is connected to the medicine cavity 11. It also includes a concentration detection module 4, a control module 5 and a visualization module 6, and the concentration detection module 4 and the visualization module 6 are both communicatively connected to the control module 5; wherein the concentration detection module 4 can be specifically a particle concentration sensor, and the concentration detection module 4 can be embedded in the side wall of the mouth suction tube 3 to detect the powder medicine concentration in the mouth suction tube 3. The control module 5 is used to obtain the powder medicine concentration information detected by the concentration detection module 4, and control the visualization module 6 to feedback the powder medicine concentration information, so that the user can know the powder medicine concentration information.

[0040] Reference Figure 2 and Figure 3 The control module 5 can be specifically a single chip microcomputer installed on the medicine box 1. The control module 5 is connected to the visualization module 6 through a wireless communication module (such as a Bluetooth module). The visualization module 6 can be specifically an intelligent terminal (such as a mobile phone, a PC or a PLC controller with a touch display). The visualization module 6 can feedback the concentration information of the powder mist medicine by displaying it using mobile phone software, or displaying it on the access page after the user visits the PC webpage, or using the PLC controller to control the touch display to display it, so that the user can know the concentration information of the powder mist medicine.

[0041] Referring to Figure 2 and Figure 3 Figure 3 , the control module 5 is also communicatively connected to a flow detection module 7 and an air flow booster 8. The flow detection module 7 is an air flow sensor, and the flow detection module 7 is embedded in the mouth suction pipe 3 for detecting the gas flow rate in the mouth suction pipe 3. The control module 5 is used to control the visualization module 6 to display the gas flow rate information in real time, and can also control the visualization module 6 to display a curve graph of the change of the gas flow rate over time. The control module 5 is also used to calculate the remaining amount of the medicament based on the gas flow rate information and the powder aerosol concentration information, and to control the visualization module 6 to update and display the remaining amount of the medicament in real time. Wherein, the remaining amount of the medicament = the amount of the powder aerosol in a single medicine capsule 25 - (gas flow rate * powder aerosol concentration).

[0042]

[0042] The air flow booster 8 can specifically be a ventilator or a suction pump connected to an oxygen source. The air flow booster 8 is connected to the medicine cavity 11 through a pipeline. The control module 5 is used to control the visualization module 6 to display startup recommendation information to the user when preset conditions are met. The specific content of the startup recommendation information can include: the content of "Do you need to start the air flow booster", and selection buttons of "Yes" and "No" for the user to touch and select. When the user touches the aforementioned selection buttons, the control module 5 generates startup feedback information with the content corresponding to the aforementioned selection buttons. And when the selection button touched by the user is "Yes", the control module 5 controls the air flow booster 8 with the startup feedback information. Wherein, the preset conditions include that when the gas flow rate information is lower than a preset flow rate threshold and the remaining amount of the medicament is not lower than a preset remaining amount threshold.

[0043]

[0043] Wherein, before using the visualization powder aerosol inhalation detection system, the user can input a preset single inhalation and exhalation duration of the user (i.e., inhalation duration and exhalation duration) through the visualization module 6. When the user starts to use the visualization powder aerosol, the control module 5 can determine the inhalation period and exhalation period of the user based on the time point when use starts and the aforementioned single inhalation and exhalation duration input by the user; correspondingly, the control module 5 is used to control the visualization module 6 to feedback startup recommendation information to the user when the current time is in the user's inhalation period and preset conditions are met, and stop feedbacking the startup recommendation information until the time difference between the current time and the end time of the inhalation period is less than a preset time difference. The control module 5 is also used to close the valve on the mouth suction pipe 3 and control the air flow booster to open for a specified duration and then reopen the valve and close the air flow booster when the current time is in the user's exhalation period and the gas flow rate information is lower than a specified flow rate, so as to dredge the mouth suction pipe 3 and reduce the occurrence of blockage of the mouth suction pipe 3.

[0044] Referring to Figure 2 and Figure 4, a cavity 12 is formed inside the medicine box 1, and a docking ring plate 13 is fixedly connected inside the cavity 12.

The lower end of the medicine supply box 2 is open and attached to the upper surface of the docking ring plate 13. A plurality of partition plates 21 are arranged along the circumferential direction inside the medicine supply box 2. The partition plates 21 divide the inner annular cavity of the medicine supply box 2 to form storage areas, including a first area 22 and a second area 23. The first area 22 and the second area 23 are alternately distributed, and the first area 22 is used to place and store medicine capsules 25, and each first area 22 can only store a single medicine capsule 25. An opening can be formed in the top wall of the medicine supply box 2 at each first area 22 and a cover plate 26 is hinged thereto, so that when any first area 22 is positioned outside the medicine box 1, the cover plate 26 can be rotated to open the opening and a supplementary medicine capsule 25 can be put into the first area 22.

A relief surface for abutting against the protrusion 27 is arranged on the side wall of each docking block 24. The relief surface is used to enable the protrusion 27 to be pressed by the docking block 24 and move away from the docking block 24 and retract into the docking ring plate 13 when the docking block 24 abuts against the protrusion 27, so as to realize the relief when the docking block 24 moves, and enable the docking block 24 to move over the protrusion 27 and move with the rotation of the medicine supply box 2.

[0046] Referring to Figure 2 , Figure 4 , Figure 5 and Figure 6 , a powder discharging assembly 9 is arranged in the medicine box 1. The powder discharging assembly 9 is used to take out the medicine capsule 25 from the medicine supply box 2 and puncture the taken-out medicine capsule 25, so that the powder mist medicine in the taken-out medicine capsule 25 can be discharged. Specifically, a medicine dropping port 131 is formed on the surface of the docking ring plate 13. When any first area 22 is positioned at the medicine dropping port 131, the medicine capsule 25 in the corresponding first area 22 will be discharged from the medicine supply box 2 through the medicine dropping port 131.

A guide plate 14 is provided on one side of the turntable 911. One end of the guide plate 14 is located above the turntable 911, and the other end is located below the medicine drop opening 131, so as to receive the medicine capsule 25 dropped from the medicine drop opening 131 and guide the medicine capsule 25 to move into the medicine cavity 11 on the turntable 911. A notch is provided on the side wall of the limit plate 915 for the medicine capsule 25 to pass through. When the second torsion spring 912 is not deformed, the notch is just opposite to the guide plate 14, so that the medicine capsule 25 on the guide plate 14 can pass through the notch and enter the medicine cavity 11.

At this time, the oral straw 3 is rotated so that the clamping block 31 is inserted into the clamping groove 111, thereby fixing the sliding position of the oral straw 3 and the medicine box 1. In addition, a filter screen (not shown in the figure) may be inserted into the inner wall of the mouth-suction tube 3, and the mesh of the filter screen is not less than the size of the powder aerosol particles so that the powder aerosol can pass through the filter screen. The filter screen is provided to prevent the capsule shell fragments of the punctured medicine capsule 25 from being inhaled into the respiratory tract of the user through the mouth-suction tube 3. After the inhalation of the powder aerosol is completed, the mouth-suction tube 3 can be taken out of the medicine box 1, and the medicine box 1 is inverted so that the capsule shell fragments can be poured out from the position where the medicine box 1 and the mouth-suction tube 3 are connected.

[0052] The implementation principle of a visualization powder aerosol inhalation detection system according to an embodiment of the present application is as follows: A medicine capsule 25 is pre-placed in the medicine supply box 2, and then the medicine supply box 2 is rotated so that one of the medicine capsules 25 is placed at the medicine dropping port 131 and falls into the medicine cavity 11. Then, the medicine supply box 2 is continuously rotated so that the docking block 24 adjacent to the medicine capsule 25 rotates to the position directly above the medicine dropping port 131 and then stops rotating. During this process, the powder aerosol component 9 is used to puncture the medicine capsule 25 so that the powder aerosol medicine detaches from the capsule shell of the medicine capsule 25. Then, the user can insert the mouth suction tube 3 into the medicine box 1 and cover the periphery of the medicine cavity 11, and then inhale the powder aerosol medicine. During the inhalation process, the concentration detection module 4 and the visualization module 6 are used to monitor and display the concentration information of the powder aerosol medicine in real time so that the user can know whether the inhalation of the powder aerosol medicine in the medicine capsule 25 is completed.

[0053] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
