CONNECTION DEVICE BETWEEN VENTILATOR AND OXYGEN CONNECTION PIPE IN NON-INVASIVE VENTILATOR

摘要

A connection device between a ventilator (1) and an oxygen connection pipe (78) in a non-invasive ventilator, comprising a ventilator (1), the upper surface of the ventilator (1) being fixedly connected to a support leg (2) and an oxygen storage box (3), an oxygen inlet device and an oxygen outlet device being provided inside the oxygen storage box (3), the oxygen inlet device comprising an oxygen inlet pipe (4), and the oxygen outlet device comprising an oxygen outlet pipe (5). When using the connection device between the ventilator (1) and the oxygen connection pipe (78) in the non-invasive ventilator, a healthcare worker rotates a buckle (81) to move an adjustment rod (80) outward, and moves a clamping block (75) outward under the pressure of a compression spring (74), and at this time, the healthcare worker can sleeve the oxygen connection pipe (78) on a fixing block (7), and rotate the buckle (81) to drive the adjustment rod (80) to press the clamping block (75) inward, so that the surface of the clamping block (75) presses and fixes the oxygen connection pipe (78), and the inner wall of the oxygen connection pipe (78) presses a second sealing ring (77), thereby achieving the effects of being easy to install, having strong sealing performance and avoiding oxygen leakage.
