Embodiment approach 1

[0037] Such as Figure 1 to Figure 7 as shown,

[0038] A wall-plug type oxygen inhaler, comprising a cup 1, a buoy flow meter 2, an upper connecting piece 3, a connector 4, and a filter collar 6.

[0039] The breast cup 1 is connected in the internal thread groove at the upper end of the connector 4 . The buoy flowmeter 2 is matched with the connector 4 through the upper connecting piece 3 and placed in the cup 1 . The upper connector 3 is provided with an axial through hole, which is installed in the slot hole 41 at the bottom of the internal thread groove at the upper end of the connector 4 . An oxygen supply chamber interface 401 and a corresponding flow adjustment knob 402 are provided on the side wall of the connector 4 . An oxygen inlet channel 43 is provided along the axial direction of the connector 4, and the oxygen supply chamber interface 401, the oxygen inlet channel 43, the axial through hole of the upper connector 3, and the buoy flowmeter 2 are sequentially ...

Embodiment approach 2

[0051] The difference from Embodiment 1 is that the upper end of the end cap 7 is provided with a stepped hole, wherein the uppermost section of the stepped hole is a light hole, and the bottom of this section is a threaded hole, and the diameter of the light hole part is larger than that of the threaded hole. aperture. The end cap 7 is matched with the connector 4 through the threaded hole. An axially extending groove (which may be a cylindrical groove) is arranged on the lower end surface of the connector 4 , and the inlet of the pressure relief channel 9 is arranged on the bottom surface of the groove. The oxygen tube interface 71 is arranged at the upper light hole portion of the end cover 7 . The upper part of the stepped hole at the upper end of the end cap 7 is a light hole and the oxygen tube interface 71 is correspondingly arranged in this part, so as not to adversely affect the threaded relationship between the end cap 7 and the connector 4 and the sealing performan...

Abstract

The invention provides a wall-mounted oxygen inhalator. The wall-mounted oxygen inhalator comprises a cup, a float flow meter, an upper connecting piece, a connector and a filtering loop, wherein a lug boss is arranged on the lower end face of the connector; a groove is formed in the lug boss; the bottom of the groove is cone-shaped and an oxygen outlet is formed in the cone-shaped wall; a lug boss is arranged on the upper end of a lower connecting piece and external threads are formed on the lug boss; a first flange and a threaded blind hole are formed at the lower end of the lower connecting piece; internal threads matched with external threads on the lower end of the connector are formed on the upper end of an end cover, and an oxygen pipe connection is formed on the wall of the end cover; external threads are formed on the upper end of an end cap, while a second flange is formed on the lower end of the end cap; a blind hole is formed in the axial direction and an oxygen discharge channel is formed in the lower end of the blind hole. The wall-mounted oxygen inhalator is simple in structure, low in processing technic requirements, compact in structure, and easy to manufacture and assemble.

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 oxygen tube interface is along the radial direction of the connector. When in use, the oxygen tube is connected to it and bends downward, which may easily lead to pressure suppression and accidents, and the oxygen flow is not smooth, which affects the treatment effect. The flow meter generally adopts a buoy flow meter. In addition, an air outlet passage inclined relative to the axial direction is provided along the axial direction of the connector, the inlet of the air outlet passage is arranged at the bottom of the thread groove at the upper end of the co...
