The invention provides lung function inspection tester pipeline bubble discharge equipment which comprises a pipeline main body, wherein a ring base is fixedly mounted on the pipeline main body; a rotating ring is moveably inserted into the ring base; impeller plates are fixedly mounted inside the rotating ring; moveable plates are moveably inserted into the impeller plates; puncture needles are moveably inserted into left sides of the impeller plates; fixing shafts are fixedly connected with ends close to the rotating rings, of the moveable plates; outer sides of the fixing shafts are moveably sleeved by baffle discs; clamping columns which extend into the rotating rings are fixedly connected with outer sides of the baffle discs; and pressing rods are moveably inserted into support bases.The impeller plates are pushed to rotate when a fluid flows inside the pipeline main body, the moveable plates are thrown outwards under the action of centrifugal force, then magnets II are staggeredfrom magnets I, the puncture needles are driven to withdraw back and forth, bubbles can be punctured off, bubbles in a pipeline can be effectively discharged, and in addition, the process is implemented automatically along with flowing of the fluid, operation guards are not needed, and the time and the labor can be saved.
Description
technical field [0001] The invention belongs to the technical field of pulmonary function testing equipment, in particular to a device 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 effective passage area ...
