Description

Technical Field

[0001] The invention relates to the technical field of automatic detection trigger devices, in particular to an automatic detection trigger device for quantitative compression dosing aerosol. Background Art

[0002] Inhalation aerosol refers to a drug-containing solution, suspension or emulsion, which is sealed together with a suitable propellant or liquefied mixed propellant in a pressure-resistant container with a quantitative valve system and a certain pressure. When used, the content is sprayed out in the form of mist with the help of the pressure of the propellant, and the preparation is inhaled through the mouth and deposited in the lungs. It is also usually called a pressure metered dose inhaler. The active substance can be quantitatively released by pressing the valve, and the drug is dispersed into particles or droplets, which are inhaled through the respiratory tract to exert local or systemic therapeutic effects.

[0003] The pressure metered-dose inhaler was introduced in the mid-1950s and is currently the most widely used inhalation drug delivery device in clinical practice. It has the advantages of being small and portable, quick-acting, easy to use, cheap, and capable of multiple doses. Its structure consists of two parts: a plastic fixing seat (including the inhalation port) and a metered-dose valve. When the user manually lifts and presses the valve, the drug and propellant are sprayed out in the form of an aerosol. Due to its uniquely designed structure, the pressure metered-dose aerosol inhaler can ensure that the amount of solution sprayed out each time it is manually pressed is within a certain range. In order to achieve the best inhalation treatment effect, the pressure metered-dose inhaler requires the user to perform a slow and deep inhalation operation while manually lifting and pressing, so as to inhale the drug mist particles into the respiratory tract and lungs. However, it is difficult for some people to ensure hand-mouth synchronization, resulting in an increase in the amount of drug mist deposited in the oropharynx, a low lung deposition rate, and a low drug utilization rate.

[0033] Reference Figure 8, the drug body detection sensor detects that the drug is loaded into the device, and the device is activated and starts working. The motion sensor is used to detect the movement and posture of the drug. Some drugs require that the drug be shaken evenly before use, and they need to be used in an upright posture. The motion sensor can detect these data, thereby reminding the user of some unqualified usage methods. The flow sensor 6110 is used to detect the flow of inhaled gas. Only when the detected flow rate continues to reach an effective inhalation rate, the control mainboard 6104 will trigger the drive control module 61. The appropriate flow rate has a great influence on the deposition rate of the drug. Too high or too low will affect the absorption efficiency of the drug. The flow sensor 6110 can detect the complete inhalation process, analyze whether the inhalation duration and inhalation strength are reasonable, and thus give more effective inhalation suggestions, thereby improving the user's absorption rate of the drug and achieving better therapeutic effects.

[0034] The trigger detection button 6106 is used to detect the working state of the drive control module 61 and feed back the signal to the control mainboard 6104. The control button 6103 is used to control the information entry and function control of the device, such as resetting the medication dosage, turning pages to view data, etc. The wireless communication module is a long-distance communication method of the device. The control mainboard 6104 collects and records the device status information and the use process information, and can send this information to the mobile phone, computer, and cloud through wireless transmission, which is more convenient for data viewing and data analysis. The wireless communication module can be a communication method such as Bluetooth, WIFI, mobile information system and other wireless communication technologies.

[0035] The working principle of the device is as follows: when in use, the driving motor 6105 rotates to drive the small bevel gear 7101 to rotate, the small bevel gear 7101 is meshed with the first reduction gear 7102, the first reduction gear 7102 is meshed with the second reduction gear 7103, the rotating cam 7104 is fixed on the second reduction gear 7103 and rotates therewith, and the rotational torque of the driving motor 6105 gradually increases after passing through the first reduction gear 7102 and the second reduction gear 7103, thereby forming a force that can drive the aerosol spray.

[0036] The rotating cam 7104 rotates to push the push plate 7105, and there is a trigger button baffle 6107 on the push plate 7105. There is a push column 7106 under the push plate 7105. The push column 7106 contacts the top of the aerosol medicine 5. The push plate 7105 moves up and down to push the push column 7106 to move up and down, thereby pushing the aerosol medicine 5 to be pressed and sprayed.

[0037] The user inhales the medicine. When the control main board 6104 detects that the flow rate has reached an appropriate flow rate, the control drive component 67 is operated, and the push rod 7106 pushes the medicine to complete a spraying. The sprayed medicine enters the lower respiratory tract of the human body with the inhaled air. After the push rod 7106 pushes the medicine, the trigger button baffle 6107 triggers the trigger detection button 6106, and the feedback signal is fed back to the control main board 6104. The control main board 6104 controls the drive component 67 to stop working, thus completing an automatic detection of medication.
