Oxygen inhaler

Abstract

The invention relates to a medical apparatus, in particular to an oxygen inhaler. Existing nasal catheters have the defects that the nasal catheters are not flexible to fix and detach, the situation of oxygen outflow is apt to cause, and the like. Most obviously, the supply and the stop of oxygen can be controlled only through insertion and takeout of an inhaling tube; patients do not have an adaptation process for conversion from oxygen to air and the oxygen is very difficult to supply again after the oxygen is stopped from supplying; only two states, i.e. an oxygen full-supply state and an oxygen full-stop state are available, and the magnitude of the supply quantity of the oxygen can be adjusted only through the adjustment of an oxygen generating device. The oxygen inhaler comprises an oxygen catheter. One end of the oxygen catheter is provided with a connecting port. The other end of the oxygen catheter is connected with the inhaling tube. The oxygen inhaler additionally comprises an adjustment mechanism. The adjustment mechanism is arranged on the oxygen catheter. An oxygen stopping plug made of polyurethane is arranged on the inhaling tube. The oxygen inhaler provided by the invention has the advantages that the structural principle is simple, the oxygen inhaler is flexible and convenient to use, the clinical effect is obvious, and the oxygen inhaler can be widely used as matching facilities for hospital clinical treatment, health keeping oxygen chamber and family oxygen supply equipment.

Description

Technical field [0001] The invention relates to a medical device, in particular to an oxygen absorber. Background technique [0002] Oxygen inhalation is used in hospital clinical treatment to correct hypoxia, increase the level of arterial blood oxygen partial pressure and oxygen saturation, and promote metabolism. It is one of the important methods to assist in the treatment of many diseases, and the nasal catheter oxygen method is It is the most widely used and effective method. [0003] However, the existing nasal catheters also have many defects, such as the fixing method is tape sticking, fixing and disassembling are not flexible; the gap between the airway tube and the nasal cavity is likely to cause oxygen leakage. But the most obvious is that the supply and stop of oxygen can only be controlled by the insertion and removal of the suction tube. In this way, the patient’s conversion from oxygen to air is completed instantaneously, without any adaptation process. Some patie...

Problems solved by technology

In this way, the conversion from oxygen to air is completed instantaneously without any adaptation process. Some patients will have symptoms of incompatibility to this instantaneous conversion; Then it has to go through a series of operations such as meter installation, gas testing, intubation, and fixation, so it is difficult to supply oxygen in time; at the same time, the existing nasal cannula only has two states of full oxygen supply and full oxygen stop. The size of the oxygen supply is only completed through the adjustment of the oxygen generator, which makes it extremely inconvenient to adjust the oxygen supply
