Description
Technical Field
The invention belongs to the field of auxiliary medical equipment, and relates to a full-automatic oxygen inhalation and discharge device.
Background
When acute hypoxia occurs in human body, pure oxygen is needed for respiratory therapy of patient, so as to achieve the purposes of improving oxygen tension of human body and improving tissue hypoxia. At present, even if a medical unit with oxygen inhalation condition really provides pure oxygen inhalation treatment condition for patients, the medical unit is also extremely limited, most of the medical units mainly adopt a nasal cannula mode for patients to inhale oxygen, the oxygen inhalation mode can increase the alveolar oxygen concentration to about 30 percent at most, and the problems that an oxygen supply device generates additional oxygen consumption due to continuous oxygen supply and the like exist; certain severe hypoxic diseases, for example: if the conditions of breathing high-concentration oxygen can be timely provided for patients in the early stage of disease occurrence, the method has important significance for the transition of disease conditions or the subsequent rehabilitation of diseases. However, the reasons why medical units have not been able to treat diseases with pure oxygen up to now are roughly as follows: 1. when pure oxygen is inhaled, special oxygen inhalation equipment is needed, and the equipment is mainly used as an oxygen inhalation mask. When the mask is used for oxygen inhalation, the mask has the function of automatically controlling oxygen supply, namely, the oxygen supply quantity can be automatically adjusted according to the lung ventilation quantity of a human body so as to meet the requirement that the human body obtains enough oxygen, and when a patient stops oxygen inhalation, the mask can automatically close oxygen supply along with the breathing rhythm of the patient so as to avoid oxygen waste. At present, medical units do not have the condition that the equipment is used for patients to inhale oxygen. 2. When a human body inhales pure oxygen, most of the inhaled oxygen is exhaled out of the human body again, for example: the oxygen absorption per minute of human body is about 10L, while the oxygen required by human body physiological metabolism is about 0.35L per minute, and about 96.5% of oxygen is exhaled out of human body. Therefore, the oxygen exhaled by the patient is urgently needed to be exhausted outside the environment where the human body is located by the specific oxygen exhausting equipment so as to prevent the oxygen from dispersing in the environment where the human body is located to generate fire accidents or form hidden dangers of the fire accidents, and the oxygen exhausting process also needs to have an automatic control function so as to prevent the temperature and the humidity of the environment where the human body is located from being influenced by too much exhausted room gas. At present, medical institutions do not have the condition that oxygen exhaled by patients can be exhausted outside the environment where human bodies are located when oxygen inhalation equipment is used for inhaling oxygen. The oxygen exhaled by the patient is dispersed in the environment of the human body. A large amount of oxygen is dispersed in the environment where the human body is located, and once the ventilation of a room is poor, a fire accident is easy to happen.

When breathing in, a negative pressure can be generated in the oxygen inhalation cavity 106 of the oxygen inhalation regulator 1, at the moment, the elastic silica gel sealing gasket I101 of the breathing regulator 1 shifts and swells towards the oxygen inhalation cavity 106 at the left side, and pushes the vertical valve rod 105 to move towards the left side, so that the oxygen supply valve seat I705 moves and the valve port I706 is opened, and oxygen is flushed into the oxygen inhalation cavity 106 for a patient to inhale; when the patient exhales, positive pressure can be generated in the oxygen exhaust cavity 206 of the exhalation regulator 2, at the moment, the elastic silica gel sealing gasket II of the exhalation regulator 2 displaces, and is sunken towards the left side and drives the vertical valve rod II to enable the exhaust valve seat II 805 to move and open the valve port II 807, so that gas exhaled by the patient in the oxygen exhaust cavity 206 is pumped out by utilizing negative pressure.
