Special automatic oxygen supply device for nursing in emergency department

Abstract

The invention discloses a special automatic oxygen supply device for nursing in an emergency department. The special automatic oxygen supply device includes an oxygen source mechanism and a pressure stabilizing control device. The oxygen source mechanism includes a main oxygen supply system and a standby oxygen supply system. The main oxygen supply system and the standby oxygen supply system are both provided with liquid oxygen storage tanks and confluence main pipes. An oxygen charging pipeline is connected to the bottom of each liquid oxygen storage tank. A floating ball regulating valve isconnected to the end of each oxygen charging pipeline. The top of each liquid oxygen storage tank is connected to the corresponding confluence main pipe through an oxygen feeding pipeline. The pressure stabilizing device includes a pressure stabilizing tank and a pressure stabilizing pump. The confluence main pipes are connected to the input end of the pressure stabilizing pump. A pressure stabilizing air outlet pipe is connected to the output end of the pressure stabilizing pump. A pressure sensor and a first solenoid valve are arranged in the pressure stabilizing air outlet pipe. The pressure sensor is connected to a control single-chip microcomputer. An oxygen using terminal system is connected to the pressure stabilizing air outlet pipe. The device can automatically realize timely supply of liquid oxygen, and can be combined with the standby oxygen system for switching use, which saves manpower. An oxygen inhaler can be automatically applied, and the operation is simple.

Description

technical field [0001] The invention relates to the technical field of emergency medical appliances, in particular to an automatic oxygen supply device for nursing in the emergency department. Background technique [0002] Medical oxygen supply is suitable for adjuvant treatment of respiratory diseases (such as asthma, bronchitis, pulmonary heart disease, etc.), heart and cerebrovascular diseases (such as coronary heart disease, myocardial infarction, cerebral hemorrhage, cerebral infarction) caused by hypoxia, and Relieve the symptoms of hypoxia; it can also be used for healthy oxygen inhalation or rapid relief of fatigue after intense mental work and physical work. [0003] In medical treatment, the oxygen supply device is mainly used in hospital wards, emergency rooms, observation rooms and operating rooms, etc. The oxygen supply methods in the oxygen supply station in the hospital can choose medical oxygen generator, liquid oxygen storage tank and busbar oxygen supply O...

Problems solved by technology

[0004] However, the current oxygen supply devices generally use automatic or manual switching of oxygen supply. The accuracy of manual oxygen supply is poor. The stability of the oxygen supply is poor. When the oxygen supply source is insufficient or the line is in a state, the alarm and oxygen supply cannot be performed in time, and the use safety is low. In addition, when the oxygen in the oxygen tank is insufficient, it cannot be automatically replenished in time from the oxygen generator. Oxygen requires manual removal of the oxygen tank from the oxygen supply pipeline for oxygen filling operation, which is complicated and affects the efficiency of oxygen supply; and the current oxygen inhaler is inconvenient to use, and the flow of oxygen is generally controlled by the switch valve, which may easily cause oxygen leakage
