Description

Portable cardiac arrest rescue machine

Technical Field

The invention relates to a machine for rescuing patients from cardiac arrest. The gun rescue can be carried out by lifting the rescue machine to the patient's side regardless of time, place and surrounding environment. Particularly, the patient can win precious gun rescue time, the breathing heartbeat is recovered, and the brain memory function is kept. Greatly improves the gun rescue survival rate of the patient with cardiac arrest.

Background

There are 300 million deaths in our country each year, one third of which is caused by cardiac arrest. Rescue survival rates for average cardiac arrest in the united states are 50% and 80% in the las vegas casino, hotel rescue survival rates. The survival rate of the heart arrest rescue in Shanghai and Beijing is lower than 1%. Most patients die on the way to the hospital. The patient's life window is only 4-6 minutes. Beyond this prime time, even if it comes down, it is a memory loss. At present, the effective treatment means for cardiac arrest is lacking clinically in China. The ABC cardio-pulmonary resuscitation technique started to emerge in the late fifties, where a established respiratory tract B-mouth-to-mouth, artificial respiration, and chest compression recovery circulation. The 2005 new guidelines made some important changes to CPR techniques. At present, the method is based on public popularization education. Unfortunately CPR does not include brain protection. The memory function of the brain of most patients cannot be recovered. Death is declared after clinical treatment with cardiopulmonary resuscitation (CPR), cardiovascular first aid (ECC), electrical defibrillation devices, and the like, without vital signs. Rescue survival rates of cardiac arrest patients in hospitals were also only 6%. There is a pressing need to develop a portable cardiac arrest rescuer, and an effective medical treatment.

Opening the suitcase, taking out the vacuum aluminum-plastic bag filled with the high-purity calcium hydride and the plastic bag filled with the purified water and provided with the suction nozzle. The lower end of the hydrogen generator is screwed out from the connecting screw ports 28 and 30, and the high-purity calcium hydride is folded and poured in and then screwed back to the original position. The pure water suction nozzle is opened to be connected with the water pump 25, and then the pure water suction nozzle is turned upside down and put back to the fixed position of the suitcase. Turning on the power supply, and setting the following parameter setting program to operate the computer. Tidal volume is the amount of gas that is introduced into the patient's lung cavity at a time. (1) Infant 10-20 ML (2) child 50-500 ML (3) adult 100-1200 ML, flow rate, i.e. total amount of gas per minute into the patient's lung cavity 0-150L/min. The venting pressure 196- -588pa (20- -60cmH 2O). The simulated breathing frequency is 6-20 times per minute. The simulated breathing cycle consists of inspiration time and expiration time, and the inspiration-expiration ratio is 1: 1.5-3. Referring to Japanese advanced medical treatment B system, the patient without vital signs is first rescued by hydrogen and then rescued by mixed gas. The working steps are that the water pump 25 pumps out the purified water 23, one path of the purified water is injected into the hydrogen generator 13 through the electromagnetic valve 26 to react with the high-purity calcium hydride to generate hydrogen gas, the reaction is an exothermic reaction, and the temperature and the pressure in the hydrogen generator 13 are displayed by the thermometer 17 and the pressure gauge 15. The temperature and pressure in the hydrogen generator 13 are controlled by the temperature sensor 21 and the pressure sensor 20, the computer control panel 6, and the amount of water injected by the solenoid valve 26. The other path enters a purified water heating coil 31 through an electromagnetic valve 27, is heated and is sprayed into a gas slow filling tank 35 through an electromagnetic valve 32 and an atomizing spray nozzle 33. The hydrogen produced by the hydrogen generator 13 enters the gas slow-filling tank 9 through the purification dry filter 19, the hydrogen heating coil 16 and the electromagnetic valve 11, enters the gas slow-filling tank 35 through the electromagnetic valve 39 alone, or is mixed with the hydrogen which is compressed by the air compressor 18 and processed by the air purification dry filter 14, enters the gas slow-filling tank 9 through the electromagnetic valve 12. The pressure of the mixture is indicated by a pressure gauge 10. The pressure and hydrogen content of the mixed gas are realized by a pressure sensor 7 and a hydrogen content sensor 8 through a computer control panel 6 and commands each electric appliance. Then enters the gas slow-filling tank 35 through the electromagnetic valve 39 and is used for moistening and atomizing. The temperature, pressure and humidity of the gas in the gas buffer tank 35 are controlled by the temperature sensor 36, the pressure sensor 38, the humidity sensor 34, and the computer control panel 6. The vacuum pump 2 works to enable the negative pressure slow charging tank 4 to generate negative pressure through the electromagnetic valve 3. The pressure and the duration of the negative pressure are required to keep 3-5 cmH2O micro-positive pressure loading state in the lung cavity channel after exhaust gas in the lung cavity is sucked out once. This is done by a pressure sensor 5 commanding the vacuum pump 2, and the solenoid valve 3, through a computer control panel 6. The patient's condition is programmed, the electromagnetic valves 37 and 41 work alternately to simulate the breathing state. The mouth and nose mask is taken to the face of the patient to be treated after all the treatment is normal.
