Description

Portable tuberculosis medicine aerosol inhalation device Technical Field The invention belongs to the technical field of medical equipment, and particularly relates to a portable tuberculosis medicine aerosol inhalation device. Background Tuberculosis is a chronic infectious disease caused by mycobacterium tuberculosis, of which tuberculosis is the most common. The medicine treatment is the core of tuberculosis control, besides oral administration and injection, the aerosol inhalation therapy can directly deliver the medicine to the focus of the lung, improve the local medicine concentration and reduce the systemic side effect, and becomes an important auxiliary treatment means. However, the aerosol inhalation devices commonly found in clinic at present have a number of defects which affect their wide application and efficacy in patient populations. Firstly, the traditional atomizer is extremely complicated in medicine adding step, a patient needs to open a medicine bottle cover, carefully pour medicine liquid into a medicine storage cup and accurately control the dosage. The process is difficult to operate for patients with inconvenient actions, vision deterioration or hand trembling, and can easily cause medicine liquid to be scattered, dose to be inaccurate and even pollute, so that medication compliance is seriously reduced. Second, the nebulization process of the prior devices is not synchronized with the spontaneous breathing rhythm of the patient. Most devices are continuously atomized after being started, when a patient exhales and ventilates, the mouth part of the device is not separated from the device, if the device still continuously atomizes liquid medicine, part of medicine can be directly scattered into the air, so that medicine waste and environmental pollution are caused, and the risk of cross infection of family members is increased. In the early stage of inhalation, patients cannot inhale the effectively atomized medicine immediately due to the delay of atomization initiation, so that the administration efficiency is low. This waste is particularly pronounced for expensive antitubercular drugs. Furthermore, many tuberculosis drugs have higher viscosity at normal temperature, and aerosol particles generated after atomization have larger and uneven particle sizes, so that the aerosol particles are difficult to deposit in deep small airways of the lung. In addition, inhalation of low-temperature mist stimulates the respiratory tract, which causes cough and discomfort of patients, and further affects smooth progress of treatment. Finally, the existing devices generally lack intelligent medical fluid management functionality. The medicine type cannot be automatically identified and matched with the optimal atomization parameters, and the output power cannot be dynamically adjusted according to the real-time change of concentration and viscosity rise of the medicine liquid in the treatment process, so that the atomization efficiency is gradually attenuated along with the treatment progress, and the dosage of the medicine in a single treatment is inconsistent. Therefore, there is a strong need in the art for a portable tuberculosis drug aerosol inhalation device that is easy to operate, can synchronize patient breathing, intelligently regulate and control aerosol parameters, and can ensure consistency of administration throughout the course. Disclosure of Invention The invention aims to provide a portable tuberculosis medicine atomization inhalation device, which solves the problems of complicated operation, medicine waste and low medicine administration efficiency in the prior art by putting in, pressing one-step medicine filling, synchronous breathing atomization, intelligent temperature control and power adjustment, thereby improving the medication compliance and the treatment effect of patients. The utility model provides a portable tuberculosis medicine atomizing inhalation device, includes medicine storage room, outflow passageway and controller, and medicine storage room is used for holding tuberculosis liquid medicine, and the entry end of outflow passageway is linked together with medicine storage room, and is provided with the atomizer between medicine storage room and outflow passageway for the liquid medicine atomizing that will flow through. The outlet end of the outflow channel is provided with a mouthpiece contact sensing unit, the outside of the outflow channel is sleeved with a suction nozzle, and the controller is electrically connected with the atomizer and used for controlling the start and stop and the power of the atomizer. The top of the medicine storage room is provided with a medicine tank groove which is configured to accommodate a bottle-shaped medicine tank, and the bottom of the medicine tank groove is provided with a cone thorn pipe. When the bottle-shaped medicine can is filled into the medicine can groove and pressed down, the flexible bottle mouth is pierced by t
