Description

Medical Oxygen Pressurized Breathing Protective Device

technical field

The patented technology of the present invention relates to a novel medical oxygen pressurized breathing protection device which can improve the utilization rate of oxygen when breathing medical oxygen in a hospital or at home.

Background technique

Oxygen is an indispensable substance in life activities. When the human body is hypoxic or will be hypoxic, the oxygen concentration of the inhaled gas is increased by supplying oxygen, the oxygen content of the arterial blood is increased, and the oxygen supply of tissue cells is improved, which is collectively referred to as oxygen therapy. Now, oxygen therapy in my country is divided into two types: oxygen therapy and oxygen health care. Generally speaking, oxygen therapy is used to correct pathological treatments, and oxygen therapy is used for critically ill patients and victims of accidents; it is used to supplement heavy mental workers, the elderly, pregnant women, and patients in the rehabilitation period of chronic diseases. Hypoxia and other sub-health groups, as well as the supplement of various environmental hypoxia is called oxygen health care. Oxygen therapy and oxygen health care use the supply of medical oxygen to improve the internal environment of the human body and promote a virtuous cycle of metabolic processes, so as to achieve the purpose of treating diseases, relieving symptoms, promoting recovery and preventing disease, eliminating fatigue, and improving health. In all the existing oxygen therapies, except that the hyperbaric oxygen chamber therapy has high pressure oxygen supply capability, other oxygen therapies are all pressureless or micro-pressure oxygen supply. The biggest difference between pressureless oxygen supply, pressurized oxygen supply, and high pressure oxygen supply is that the oxygen utilization rate is less than 10% when there is no pressure oxygen supply, that is, the oxygen utilization rate is very low, while pressurized oxygen supply, high pressure oxygen supply The oxygen utilization rate of the plant is relatively high, and the oxygen utilization rate can reach as much as 10% to 40%. Although hyperbaric oxygen chamber therapy has the advantages of high oxygen utilization rate, it also has many disadvantages such as high medical expenses and troublesome medical treatment. Modern oxygen therapy technology is gestating and calling for the advent and emergence of new pressurized oxygen therapy.

Invention patent content

At present, the oxygen pressure provided by the hyperbaric oxygen chamber in general hospitals is about 0.2 MPa. The purpose of the patent of the present invention is based on the existing oxygen therapy, combined with electronic technology and automatic control technology, to develop and provide a hyperbaric oxygen breathing protection device that can breathe in hospitals and at home. The oxygen pressure supplied is only controlled at 0.15MPa, which is not as high as the oxygen pressure supplied by the hyperbaric oxygen chamber, so the respiratory protection device is named "medical oxygen pressure respiratory protection device", but its essence is a medical hyperbaric oxygen breathing protection device. device.

The purpose of patent of the present invention is achieved like this:

A medical oxygen pressure breathing protection device. It consists of a special four-way tube, a special pressure reducer, two solenoid valves controlled by a time circuit (one is an inspiratory solenoid valve and the other is an exhalation solenoid valve), and it is made of medical silicone rubber material. It consists of face mask, earmuffs and airway. The medical oxygen pressurized breathing protection device is matched with the medical oxygen cylinder with sufficient medical oxygen to generate and provide pressurized medical oxygen for personnel to breathe, so as to achieve the purpose of curing diseases and saving lives. It is characterized in that: the special special-purpose four-way tube has four connection ports, each port is connected to the airway by a quick joint connection; the special pressure reducer can control the oxygen pressure output by the medical oxygen cylinder In the range of ≤0.15MPa; the inlet end of the special pressure reducer can be connected with the gas outlet of the medical oxygen cylinder; The air intake end is connected, and the outlet end of the suction solenoid valve is connected to a port of the special four-way pipe through the air guide tube; the air intake end of the exhalation solenoid valve is connected to the second port of the special four-way pipe through the air guide tube connected, the outlet port of the exhalation solenoid valve leads to the atmosphere; the time circuit that controls the two solenoid valves to open in turn is a time circuit that can be adjusted at will by adjusting the potentiometer, and can be adjusted according to the breathing frequency of a specific person The opening and closing frequency of the two electromagnetic valves (such as a person exhaling and inhaling 30 times per minute, then adjusting the opening and closing actions of each electromagnetic valve to 30 times); the mask made of the silicone rubber material , the air inlet and outlet of the mask are connected to the third port of the four-way pipe through the air guide tube; the earmuffs made of silicon rubber material are two, each earmuff is hollow, and the earmuffs are hollow One end leads to the cochlea of the oxygen inhaler, and the other end of the hollow earmuff is called the air inlet and outlet, which is connected to the fourth port of the four-way tube through the air guide tube. When a person needs to breathe medical oxygen under pressure, wear the mask and earmuffs and connect the special four-way pipe, solenoid valve, pressure reducing valve, and medical oxygen cylinder through the air guide tube, open the main valve of the oxygen cylinder, and open the When the pressure reducer valve is turned on, the timing circuit power switch is turned on, and the two solenoid valves are opened and closed regularly and cyclically. At this time, the personnel can breathe pressurized medical oxygen.

The invention patent has the following positive and beneficial effects:

Two hollow earmuffs ensure that the air pressure on both sides of the eardrum (eardrum) is always the same when the person breathes pressurized medical oxygen, which avoids possible damage to the eardrum due to air pressure difference. The special pressure reducer ensures that the oxygen pressure that the oxygen inhaler breathes is always ≤0.15MPa, and the internal organs will not be damaged due to excessive breathing oxygen pressure caused by human factors. After the implementation of the patent of the present invention, hyperbaric oxygen therapy can enter the family, which can greatly save medical expenses.
