Problems solved by technology

The existing oxygen inhaler has the following defects: (1) Because the bottle cap, the regulating valve, and the flow meter are integrated, the structure is complex and the production cost is high; (2) Because the oxygen inhaler is repeatedly used, the Disinfection treatment is required, but the disinfection operation is complicated and incomplete, which can easily cause nosocomial infection and bring undue complications to patients; (3) every time it is used, the user (such as a nurse) needs to put the humidification bottle Filling the humidification fluid inside is not only complicated to operate, but also usually uses physiological saline as the humidification fluid in order to save trouble, which is expensive and increases the burden on patients

Embodiment 1

[0027] Such as Figures 1 to 3 As shown, the oxygen inhaler is mainly composed of a humidification bottle 1, a bottle cap 2 and a flow display and adjustment device 5, wherein the flow display and adjustment device 5 includes an axially extending transparent body 50 and a first An air inlet port 501 , a valve chamber 502 , a first air channel 503 , a second air channel 504 and a first air outlet port 505 . The body 50 can be injection molded using medical polymer materials.

[0028] The first air inlet port 501 is located on one side of the lower end of the body 50 , and its axis is perpendicular to the axis of the body 50 . The first air inlet port 501 is provided with an external thread, and the external thread matches the internal thread at one end of the adapter 51 . Since the terminal sockets for inserting the oxygen inhaler have different models, the versatility of the oxygen inhaler can be enhanced by providing a detachable conversion joint 51 on the first air inlet po...

Embodiment 2

[0034] Such as Figure 4 , 5 As shown, the difference between the flow display and adjustment device 5 and the embodiment 1 is that the valve chamber 502 is arranged on the upper end of the body 50 and is located between the first air passage 503 and the second air passage 504. This structure can further simplify The structure of the flow display and adjustment device 5 reduces the cost and is small in size. In addition, the connection mode between the flow display and adjustment device 5 and the bottle cap 2 is also different. In this embodiment, the first air outlet port 505 extends into the humidification bottle 1 from the second air inlet port 21 and is locked by the nut 24. This completes the assembly of the oxygen inhaler.

Abstract

The invention discloses a flow displaying and regulating device of an oxygen inhalator, which comprises a body which extends axially, and a first air inlet interface, a valve chamber, a first air passage, a second air passage and a first air outlet interface which are arranged on the body. The valve chamber is provided with an air inlet and an air outlet; the air inlet is conical and is further communicated with the first air inlet interface; a valve core is mounted in the valve chamber; the inner end of the valve core is conical and can be matched with the air inlet; the first air passage extends along the axial direction of the body; the lower end of the first air passage is communicated with the air outlet of the valve chamber; the upper end of the first air passage is communicated with the first air outlet interface; a floating ball capable of freely moving vertically is mounted in the first air passage; and the first air outlet interface is arranged at the lower end of the body. The flow displaying and regulating device provided by the invention and a bottle cap adopt a detachable structural design; the structure of the flow displaying and regulating device is greatly simplified; and the processing cost is low. The invention further discloses an oxygen inhalator comprising the flow displaying and regulating device of the oxygen inhalator.

Description

technical field [0001] The invention relates to a device for affecting the patient's respiratory system by means of gas treatment, in particular to a flow display and adjustment device for an oxygen inhaler, and an oxygen inhaler with the flow display and adjustment device. Background technique [0002] Oxygen inhaler is one of the very important parts of conventional oxygen delivery equipment in hospitals, and it is also one of the necessary tools for rescuing and nursing critically ill patients. The existing oxygen inhaler is mainly composed of a humidification bottle, a bottle cap that can be connected with the humidification bottle, and an air inlet port, an air outlet port, a regulating valve, a flow meter and an airway arranged on the bottle cap. and flow meter as one structure. The existing oxygen inhaler has the following defects: (1) Because the bottle cap, the regulating valve, and the flow meter are integrated, the structure is complex and the production cost is ...
