Abstract

The invention discloses a device for storing, displaying and analyzing a PEFR (Peak Expiratory Flow Rate) measured value. The device comprises a circuit system , wherein the circuit system is used for storing, displaying and analyzing the PEFR measured value and comprises a resistor component which is formed by connecting multiple resistors in series, a main wire which is in parallel arrangement with the resistor component, a power supply which is connected between the resistor component and the main wire, a circuit-based PEFR display which is used for storing, displaying and analyzing a current value and a moving switch which is bridged between the resistor component and the main wire, and a loop circuit is formed by matching the moving switch with the power supply, the main wire, the PEFR display and the resistor component; the moving switch is driven to move by the circuit system through expiration airflow so that a resistance value of the resistor component can be increased or reduced, different current values can be stored, displayed and analyzed by the PEFR display so that the storing, the displaying and the analyzing of the PEFR measured value can be realized. According to the device disclosed by the invention, monitoring results in each time can be continuously stored, data are complete, and the data are beneficial for objective evaluation of illness.

Description

Technical field: [0001] The invention relates to the field of medical products, in particular to a device for storing, displaying and analyzing measured values ​​of expiratory peak flow velocity. Background technique: [0002] Pulmonary ventilation function is of great significance in the diagnosis, condition evaluation and curative effect observation of respiratory diseases, but pulmonary ventilation function can only be tested in the hospital, which is expensive and cannot be observed dynamically; while the peak expiratory flow rate can indirectly reflect the pulmonary ventilation function. Situation, simple operation, low cost, is currently the gold standard for judging whether the condition of bronchial asthma is stable. [0003] However, the traditional peak expiratory flow measurement device has the following disadvantages: the nozzle of the blowpipe is round and fixed in size, which is prone to air leakage; at the same time, the traditional peak expiratory flow measur...
