Air bubble discharge equipment in the pipeline of pulmonary function testing instrument

Abstract

The invention provides a device for discharging air bubbles in the pipeline of a pulmonary function testing instrument, which includes a pipeline main body, a ring seat is fixedly installed on the pipeline main body, and a swivel is movably inserted into the inside of the ring seat, and an impeller plate is fixedly installed inside the swivel ring, and the impeller plate The inside of the impeller plate is movably plugged with a movable plate, the left side of the impeller plate is movably connected with a needle, the end of the movable plate close to the swivel is fixedly connected with a fixed shaft, the outer side of the fixed shaft is movably sleeved with a baffle plate, and the outer side of the baffle plate is fixedly connected There is a card column extending to the inside of the swivel ring, and a pressing rod is movably inserted into the inside of the support. When the fluid flows inside the main body of the pipeline, the impeller plate is driven to rotate, and the movable plate is thrown outward under the action of centrifugal force, which makes the second magnet and the first magnet misaligned, drives the needle to stretch back and forth, and then punctures the air bubbles, which can effectively blow the pipeline The air bubbles inside are discharged, and this process is carried out automatically with the flow of the fluid, without human supervision, saving time and effort.

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 ...
