Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to a digital intelligent device for detecting hand-mouth coordination of an aerosol inhaler. Background Art

[0002] As the most direct way of medication, inhalation medication has the advantages of reaching the target organ quickly, rapid onset of action, good efficacy and few side effects. It is increasingly widely used and popularized in China. However, inhalation medication requires users to have certain inhalation skills. Good mastery of inhalation skills has a huge impact on the user's medication effect.

[0003] COPD and asthma are indications for inhaled medication and rely on long-term medication. Whether the medication is used regularly and correctly is directly related to the control of the disease. At the same time, for users of such diseases, timely understanding of their condition can help reduce the number of acute attacks and hospitalizations, effectively slow down the progression of the disease, and reduce medical insurance and personal expenses of patients.

[0004] Aerosol medication requires a lower inhalation ability of the patient, and is more user-friendly for patients with severe symptoms or poor airway conditions, because aerosol is a form of active drug administration, so patients can inhale the drug into the lungs at a lower inspiratory flow rate. However, aerosols have certain requirements for the patient's hand-mouth coordination, and the hand-mouth coordination directly affects the patient's medication effect. Hand-mouth coordination refers to the consistency between the hand pressing the spray can's spray action and the patient's inhalation action. For example, if the hand presses the spray can, the medicine has been sprayed out, and the patient has not actively inhaled, most of the medicine remains in the mouth, making it difficult to reach the lungs, and the patient's condition is difficult to be effectively treated. Therefore, the hand-mouth coordination directly affects the patient's medication effect.

[0005] Aerosol inhalers are a type of inhaler and are used to a certain extent. Existing aerosol inhalers usually include two major parts, including a spray can and a presser with a nozzle and a nozzle protection cover. The spray can and the presser can be separated. When in use, the spray can needs to be placed in the inner cavity of the presser, and the top of the spray can is pressed by external force to drive the spray can to move in the inner cavity of the presser. After moving a certain distance (not to the bottom), a certain amount of aerosol in the spray can will be sprayed out through the nozzle of the presser to complete the drug delivery action.

[0006] Since the spraying process of aerosol only takes about 200ms, the spraying time is very short, so when using aerosol, users need to start inhaling the medicine as soon as possible to ensure that as much medicine as possible is inhaled into the lungs. This requires users to have a certain hand-mouth coordination when using aerosol medicine. Therefore, it is necessary to use equipment for hand-mouth coordination detection to understand the hand-mouth coordination status of users.

[0007] The applicant has discovered that there are at least the following technical problems in the prior art: the existing hand-mouth coordination detection equipment is unable to accurately collect the time of drug injection and has a large error. In addition, since the presser and the spray can are installed on the detection equipment, the presser and the spray can may shake in the front, back, left and right directions, thereby interfering with the collection of the drug injection time.

[0008] The purpose of the present invention is to provide a digital intelligent device for detecting hand-mouth coordination of an aerosol inhaler to solve the technical problems existing in the prior art.

[0038] To make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be described in detail below. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other implementation methods obtained by ordinary technicians in this field without creative work belong to the scope of protection of the present invention.

[0040] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances.

[0041] Reference Figures 1 to 7 The present invention provides a digital intelligent device for detecting hand-mouth coordination of an aerosol inhaler, comprising a housing unit 1, a trigger component 2 and a detection module 3.

[0042] The housing unit 1 preferably includes an upper front housing 11, a lower front housing 12 and a rear housing 13. The upper front housing 11 is detachably connected to the lower front housing 12, and the rear housing 13 is detachably connected to the upper front housing 11 and the lower front housing 12. The above connections are preferably connected by bolts to make disassembly and assembly more convenient and quick.

[0043] The presser 4 and the spray can 5 can be installed and removed as a whole relative to the housing unit 1. The upper front housing 11 and the lower front housing 12 are both provided with slot structures for the spray can 5 to pass through. During installation, the presser 4 can be installed as a whole on the housing unit 1 from bottom to top, and then the spray can 5 can be inserted from the slot structure into the inner cavity of the presser 4 from top to bottom, so as to quickly complete the installation. During disassembly, the spray can 5 can be removed first, and then the presser 4 can be removed. The slot structure can ensure smooth installation of the spray can 5, and can also ensure that the spray can 5 can move relatively in the vertical direction through the slot structure during use.

[0044] The trigger component 2 and the detection module 3 are both connected to the housing unit 1. A matching surface 51 is provided on the spray can 5. When the spray can 5 is driven downward by an external force, the spray can 5 can form an extrusion contact with the presser 4 to spray the medicine. At the same time, the matching surface 51 can contact the trigger component 2 and drive the trigger component 2 to move. During the movement, the trigger component 2 can trigger the detection module 3. The detection module 3 is used to collect the time point of the medicine injection. With such a configuration, the time point of the medicine injection collected by the detection module 3 and the time point when the spray can 5 actually injects the medicine can be synchronized. The time of the medicine injection can be accurately collected by recording the triggering situation of the detection module 3. On this basis, the hand-mouth coordination of the user can be easily understood and mastered. At the same time, by assembling it into a digital intelligent device, it can help and guide the user to improve his hand-mouth coordination.

[0045] The upper front shell 11 and the lower front shell 12 of the shell unit 1 are jointly provided with a fixing component. When the upper front shell 11 is connected to the lower front shell 12, the fixing component can fix the presser 4 so that the presser 4 is firmly connected to prevent the presser 4 from shaking. At the same time, the fixing component can limit the moving direction of the spray can 5 to prevent the spray can 5 from tilting, so that it can only move in the moving direction limited by the fixing component. The above-mentioned settings can minimize the interference of the presser 4 and the spray can 5 with the collection of the drug injection time due to unnecessary shaking and wrong displacement direction, and further promote the drug injection time point collected by the detection module 3 to coincide with the time point when the spray can 5 actually injects the drug.

[0046] As an optional embodiment, the fixing assembly preferably includes a barb structure 71 and a supporting claw structure 72, and both the barb structure 71 and the supporting claw structure 72 are used to fix the press 4;

[0047] Specifically, the barb structure 71 is connected to the inner side of the slot structure of the upper front shell body 11, and is preferably located at the rear end of the inner side of the slot structure. Since the slot structure is circular in shape, the outer shape of the barb structure 71 matches the shape of the slot structure, and the inner shape of the barb structure 71 matches the shape of the upper outlet edge of the press 4, so that the barb structure 71 can fix the upper outlet edge of the press 4. The barb structure 71 can adopt a continuous structure or an intermittent structure. In this embodiment, the upper outlet edge of the press 4 is a relatively regular circle. The barb structure 71 preferably adopts an intermittent structure. The upper outlet edge of the press 4 is inserted into the inner side of the barb structure 71 through the barb structure to fix the upper outlet of the press 4.

[0048] The support claw structure 72 is symmetrically connected to the bottom of the lower front housing 12. The support claw structure 72 can fix the lower end of the presser 4. The support claw structure 72 includes two symmetrical supporting parts, and a convex structure is formed at the front end of the supporting part. The support claw structure 72 can support the lower end of the presser 4 through the supporting part and fix the lower end of the presser 4 through the convex structure at the front end.

[0049] The barb structure 71 cooperates with the supporting claw structure 72 to fix the upper and lower ends of the presser 4 respectively, and finally achieves the overall fixation of the presser 4, ensuring that the presser 4 will not shake randomly after being installed, so as to facilitate more accurate collection of the spraying time.

[0050] As an optional implementation, after the presser 4 is fixed, the spray can 5 also needs to ensure that it can move in the vertical direction. Therefore, the fixing component preferably also includes a limiting guide structure 73. The limiting guide structure 73 is connected to the inner side of the slot structure of the upper front shell 11 and is relatively located in front of the spray can 5. The limiting guide structure 73 is preferably a plurality of strip structures protruding inward so that it can contact the front end wall of the spray can 5, thereby preventing the limiting guide structure 73 from tilting forward and allowing it to move only along the limiting movement direction of the limiting guide structure 73, specifically, moving closer to the rear and vertically downward. Such a setting can reduce the interference caused by the shaking of the spray can 5, so that the drug injection time point collected by the detection module 3 is more consistent with the actual injection time point of the spray can 5.

[0051] As an optional embodiment, the trigger assembly 2 includes a positioning column 21, a return spring 22, a displacement detection guide column 23 and a fixed plate 24, the fixed plate 24 is connected to the upper front shell 11 of the shell unit 1, the positioning column 21 is connected to the fixed plate 24, the return spring 22 is sleeved on the outside of the positioning column 21, and the displacement detection guide column 23 is sleeved on the outside of the return spring 22. The displacement detection guide column 23 can move axially relative to the positioning column 21, and can compress the return spring 22 in the process of moving toward the fixed plate 24, and can restore the return spring 22 when moving away from the fixed plate 24.

[0052] The detection module 3 is preferably a touch switch, which can be triggered after being hit;

[0053] The mating surface 51 is preferably an inclined surface and matches the shape of the front end of the displacement detection guide column 23. It is assumed that the spray can 5 will trigger the spraying after it moves vertically downward for a certain distance in the inner cavity of the depressor 4. The distance is less than the distance of pressing to the bottom, and the distance is assumed to be h. When the spray can 5 moves the corresponding h distance in the inner cavity of the depressor 4, the mating surface 51 arranged obliquely on the spray can 5 can form contact with the front end of the displacement detection guide column 23. At the same time, the displacement detection guide column 23 can be close to the touch switch but will not trigger the touch switch. When the spray can 5 reaches the h distance and continues to move, it can drive the displacement detection guide column 23 to move toward the fixed plate 24, so that the displacement detection guide column 23 touches the touch switch during the movement, thereby accurately collecting the time point of drug spraying;

[0054] After the external force pressing the spray can 5 is released, the spray can 5 will be lifted up, and the return spring 22 can drive the displacement detection guide column 23 to return to its original position after the external force is released.

[0055] In this embodiment, in order to improve the triggering effect between the displacement detection guide column 23 and the touch switch, the displacement detection guide column 23 preferably includes a column body 231 and a touch block 232. The column body 231 is sleeved on the outside of the reset spring 22, and the touch block 232 is connected to the outside of the column body 231. The touch block 232 and the touch switch are located in the same plane and the touch switch is located in the moving direction of the touch block 232. Such a setting can make the touch block 232 and the touch switch actually touch through the refined design of the touch block 232, further accurately collect the time point of drug injection, and improve the triggering effect.

[0056] In this embodiment, in addition to the touch switch structure, the detection module 3 can also adopt many other structures, including but not limited to photoelectric switches, pressure switches and Hall switches, etc., all of which can achieve accurate collection of spraying time with the cooperation of the trigger component 2. In conjunction with this, the specific structure of the trigger component 2 will also change with the different trigger forms of different switches. The specific structure of the trigger component 2 and the detection module 3 can be flexibly selected according to actual usage requirements.

[0057] As an optional embodiment, the digital intelligent device further includes an airflow collection unit 6, which is connected to the housing unit 1 and extends into the inner cavity of the depressor 4, and the airflow collection unit 6 can collect and detect the airflow in the inner cavity of the depressor 4;

[0058] The airflow collection unit 6 preferably includes an airflow collection tube 61 and a sensor 62. The sensor 62 is connected to the housing unit 1 and is electrically connected to the control module 81. One end of the airflow collection tube 61 is connected to the sensor 62 and the other end thereof extends into the inner cavity of the depressor 4. The airflow collection tube 61 can help the sensor 62 collect airflow changes in the inner cavity of the depressor 4.

[0059] In this embodiment, the sensor 62 is preferably a pressure sensor, but other forms of sensors may also be flexibly selected according to actual use requirements.

[0060] The working principle of the airflow collection unit 6 is as follows: when the patient holds the nozzle of the presser 4 in his mouth to inhale the medicine, the inside of the presser 4 is under negative pressure. Since one end of the airflow collection tube 61 extends into the inner cavity of the presser 4 and is connected thereto, the inside of the airflow collection tube 61 is also under negative pressure. When the pressure sensor detects that there is a negative pressure inside the airflow collection tube 61, it proves that an inhalation action has occurred. When the pressure sensor detects that there is no negative pressure inside the airflow collection tube 61, it proves that the inhalation action has not occurred or has ended.

[0061] The airflow collection unit 6 can be used in conjunction with the trigger component 2 and the detection module 3 to record the inhalation process by collecting airflow changes and to record the spraying time by recording the triggering time of the detection module 3. The two recorded quantities can be integrated to determine the hand-mouth coordination situation.

[0062] As an optional embodiment, the digital intelligent device further includes a control module 81, a display module 82 and a reminder module 83, the control module 81 and the reminder module 83 are arranged inside the rear housing 13, the display module 82 is arranged outside the rear housing 13, and the control module 81 is electrically connected to the display module 82, the reminder module 83 and the detection module 3 and the sensor 62 respectively;

[0063] The control module 81 is used to collect and analyze the electrical signal data of other modules, switches and sensors;

[0064] The display module 82 is preferably a display screen, which can display data status and judgment results;

[0065] The specific structure of the reminder module 83 is preferably a speaker, which can serve as a reminder by making sounds. When the detection module 3 is triggered, it makes a sound to remind the user that the medicine has been sprayed. Similarly, because it takes 3 seconds to inhale, the reminder module 83 can make a sound reminder time when the medicine is inhaled for 3 seconds.

[0066] The above are only specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art who is familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
