Abstract

The invention discloses a wall outlet oxygen inhalator, and the wall outlet oxygen inhalator comprises a cup, a buoy flow gauge, an upper connecting element, a connector, a filter ring, a lower connecting element, an end cover and an end cap; the upper end of the lower connecting element is matched with the lower end of the connector; the upper end of the end cover is matched with the lower end of the connector; the outer wall of the upper end of the end cap is provided with an external screw thread, and the lower end thereof is provided with a second flange extended in a radial direction; the end cap is axially provided with a blind hole, and the lower end of the blind hole is provided with an oxygen exhaust passageway; the filter ring is sleeved on the end cap; the blind hole on the end cap is connected with the upper through hole of the lower connecting element; the connector is provided with a pressure relief passageway whose outlet is provided with a pressure relief valve; the lower end of the connector is provided with an axial slot whose bottom is provided with a pressure relief passageway inlet; the slot wall on the corresponding connector is provided with an oxygen pipe port; an elastic element is arranged in the slot and provided with an axial through hole. The wall outlet oxygen inhalator has the advantages of simple structure, being convenient to process and manufacture, the pressure relief passageway is arranged on the connector such that the inhalator has the above university and can be applied to ordinary oxygen inhale or atomization inhalation.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to a wall-plug oxygen inhaler. Background technique [0002] The currently used wall-plug oxygen inhaler includes a cup, a flow meter, a connector, a filter ferrule and a humidification bottle, and the connector is provided with an oxygen supply chamber interface, a flow adjustment knob and an oxygen tube interface. The flow meter generally adopts a buoy flow meter. In addition, along the axial direction of the connector, an air outlet channel and an oxygen exhaust channel inclined relative to the axial direction are provided. The lower end face of the connector is arranged, and the outlet is arranged on the peripheral wall of the connector. Since there are many axially inclined channels (gas outlet channels, oxygen exhaust channels) on the connector, the processing technology is complicated, and special molds are required, resulting in low production efficiency.
