Inhalation training instrument for pulmonary inhalation administration

Abstract

The invention belongs to the technical field of medical instruments and provides an inhalation training instrument for pulmonary inhalation administration. The inhalation training instrument comprisesa tank, an inhalation cylinder, a resistance regulator, a flow sensor, a signal converter and a data analysis part. The inhalation cylinder can rotate around the axis of the tank. Along with rotationof the inhalation cylinder, fan-shaped regulating holes in the resistance regulator coincide with different vent holes, so that resistance borne by airflow is regulated, the flow sensor measures actual flow, the actual flow is converted by the signal converter and then transmitted to the data analysis part, the data analysis part calculates inhalation acceleration, inhalation peak flow velocity and inhalation volume according to flow data, and the data are displayed through a displayer of the data analysis part. According to the inhalation training instrument for pulmonary inhalation administration, the data results such as the inhalation acceleration, the inhalation peak flow velocity and the inhalation volume are visualized, a patient is helped to train the inhalation mode, the pulmonary deposition rate of medicine and the uniformity of delivery dosage are improved, and the patient can obtain a better treatment effect in inhalation medicine treatment.

Description

technical field [0001] The invention belongs to the technical field of medical equipment, and in particular relates to an inhalation training instrument for lung inhalation drug delivery. Background technique [0002] The pulmonary inhalation drug delivery method is to use a special inhalation device to disperse the drug into an aerosol for patients to inhale to exert local or systemic therapeutic effects. The clinical effect of drug administration is affected by the use of inhalation devices by patients. According to different types of inhalation devices, inhaled drugs can be divided into nebulizers, pressure metered dose aerosols (pMDI), powder inhalers (DPI), soft mist (SMI) Wait. Each inhalation device has a different principle of dispersing the drug into an aerosol, and the patient also needs to adopt different inhalation methods to cooperate with inhalation of the aerosol during use. Nebulizers, pressure metered dose inhalers (pMDI) and soft mist inhalers (SMI) are i...

AI Technical Summary

Problems solved by technology

[0003] At present, at home and abroad, the patient's inhalation during pulmonary administration is only based on the oral guidance of the medical worker to the patient, and the doctor cannot intuitively obtain reference data such as inspiratory peak flow rate, inspiratory acceleration, and inspiratory volume during the guidance process. Patients can only be guided by experience and abstract descriptions

Therefore, when patients use inhaled drugs, they lack an intuitive understanding of the way of inhalation, and there are large differences in individual feelings, large inhalation variability, and high heterogeneity. Effect
