The invention provides a method for discharging air bubbles in a pipeline of a lung function tester. The discharge of air bubbles is realized by using a device for discharging air bubbles in the pipeline of the lung function tester. When the fluid flows in the pipeline main body, impeller plates are pushed to rotate, and a movable plate is thrown outwards under the action of centrifugal force, so that magnets II and magnets I are staggered. Because the magnets II are arranged in a staggered manner with opposite magnetism, the magnets I drive a pricker to stretch back and forth under the back-forth changing action of the attraction and repulsion of the magnets II during the moving process of the movable plate. When the air bubbles exist in the pipeline main body, the air bubbles are pierced by the pricker, the air bubbles in the pipeline are discharged, the air bubbles in the pipeline can be effectively discharged, the process is automatically carried out along with the flow of the fluid, people do not need to watch the process, and time and labor are saved.
Description
technical field [0001] The invention belongs to the technical field of pulmonary function testing equipment, and in particular relates to a device and method for discharging air bubbles from a tube of a pulmonary function testing instrument. Background technique [0002] Pulmonary function test plays a very important role in the diagnosis and treatment of lung diseases. There are many items of pulmonary function test. Pipelines are all arranged on these inspection instruments to transmit medicinal liquid or fluid to be detected. [0003] Pulmonary function testing instruments generally empty the air in the pipeline before use, but in actual use, there are often cases where the air is not completely exhausted, and fluids such as medicine and blood also contain certain gases Therefore, during the transmission of these fluids inside the pipeline of the tester, bubbles often occur. The bubbles trapped in the pipeline will occupy the internal space of the pipeline, reducing the ...
