Portable lung function instrument and lung function detection method

Abstract

The invention discloses a portable lung function instrument and a lung function detection method. The portable lung function instrument comprises a disposable ultrasound respiratory pipeline, a control mainboard and a liquid crystal display, wherein the ultrasound respiratory pipeline comprises a barrel-shaped main pipeline; one end of the main pipeline is a horn-shaped inlet; the other end of the main pipeline is a sealed outlet; the side wall of the top and the side wall of the bottom of the main pipeline are respectively provided with a top window and a bottom window; the top window and the bottom window are arranged at a certain inclination angle relative to each other; the top window and the bottom window are respectively sealed by a flake; the outer side of the flake on the top window is also provided with a first pipeline according to the extension direction of the inclination angle; the outer side of the flake on the bottom window is also provided with a second pipeline according to the extension direction of the inclination angle; a first ultrasonic wave sensor and a second ultrasonic wave sensor are respectively arranged in the first pipeline and the second pipeline. The instrument has the characteristics of high integration design, and convenience in carrying. Due to the fact that the lung function detection is carried out by the ultrasonic principle, the detection precision is higher, and a detection result is more favorable for the medical diagnosis of patients.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a portable lung function instrument and a lung function detection method. Background technique [0002] Pulmonary function test is an important examination content of clinical chest and lung diseases and respiratory physiology. For early detection of lung and airway lesions, identification of causes of dyspnea, diagnosis of lesion sites, evaluation of disease severity and prognosis, evaluation of efficacy of drugs or other treatments, evaluation of lung function tolerance to surgery or labor intensity Pulmonary function tests are essential for tolerance and monitoring of critically ill patients. [0003] In the field of medical devices, lung function testing equipment is widely used in many lung function testing items; among them, lung function testing equipment (that is, the existing lung function testing instrument) can perform lung function testing and track lung heal...

Problems solved by technology

However, the above-mentioned partition net is easy to deposit harmful substances to indicate mesh blockage and bacteria. It is difficult to clean and disinfect the above-mentioned differential pressure pulmonary function testing equipment. In addition, such a mechanical detection method has a very large error in high-flow measurement.

[0007] In addition, the existing lung function testing equipment uses a mechanical mechanism for detection, so it occupies a relatively large area and cannot be carried around. It can only be used at the treatment site and cannot be used casually.
