Abstract
Description
Technical Field
[0001] The invention belongs to the technical field of gas detection, and in particular relates to a medical gas alarm device with a state monitoring function. Background Art
[0002] Nitrous oxide, also known as laughing gas, is an oxidant that is currently used in surgical and dentistry for anesthesia and analgesia. It is a gas that is used more frequently in hospitals. Since laughing gas is an anesthetic, if people are exposed to high concentrations of laughing gas for a long time, it will lead to insufficient oxygen supply and may cause hypoxemia. It can also cause nitrous oxide poisoning, and symptoms such as nausea, dizziness, headache, and neurological problems. Due to these potential risks and side effects, medical professionals will strictly control the concentration and time when using laughing gas to ensure the safety and health of patients.
[0003] When medical personnel use laughing gas, there are the following disadvantages: When using nitrous oxide, medical personnel need to take out the gas tank storing nitrous oxide from the storage warehouse and then transport it to the operating room. Then the medical personnel insert one end of the gas pipeline into the gas tank, and then connect one end of the gas pipeline to the mask. Then, the nitrous oxide in the gas tank can be controlled to be transported into the mask. When the patient inhales the nitrous oxide from the mask into the body, it will have an anesthetic effect. After inserting the gas pipeline into the gas tank, medical staff will often pull the gas pipe when moving it, which will easily cause a gap between the gas pipe and the plug of the gas tank. When the gas tank is used for a long time, the gap between the gas tank and the gas pipe will gradually become larger, and the compressed nitrous oxide in the gas tank will easily leak out from the gap, thereby increasing the concentration of nitrous oxide in the operating room. When the leaked nitrous oxide is inhaled by medical staff, it will affect their concentration during surgery, making major medical accidents likely to occur.

[0028] The operating principle of the present invention is described as follows: the gas cylinder 2 is placed on the mobile seat 1 and fixed, and the gas cylinder 2 is transported to the operating room by the mobile seat 1. After the gas cylinder 2 is placed in the operating room, the placement rack 8 and the working box 9 are fixed to the outside of the gas cylinder 2 by the clamp 7, and then the position of the suction cylinder 102 and the spiral tube 50 is adjusted, and then the connecting tube 5 is passed through the spiral tube 50 and the suction cylinder 102, and the left end of the connecting tube 5 is inserted into the plug tube 3, and then the gas cylinder 2 is placed in the operating room. The external control button transmits external current to the upper electric contact plate 31, the upper electric contact plate 31 contacts the lower electric contact plate 32, and the lower electric contact plate 32 is electrically connected to the normally closed electromagnetic valve 4. When the upper electric contact plate 31 is energized with current, the upper electric contact plate 31 transmits external current to the lower electric contact plate 32, and the lower electric contact plate 32 transmits current to the normally closed electromagnetic valve 4. After the current is energized, the normally closed electromagnetic valve 4 will open, and the laughing gas compressed in the gas storage cylinder 2 will be transmitted to the mask through the plug-in tube 3, the connecting tube 5 and the hose 6. The patient inhales laughing gas into the body. When the external control switch transmits the external current to the upper power contact plate 31, the external current is also transmitted to the metal plate 41 synchronously. The metal plate 41 contacts the lower end of the resistor plate 42, and the upper end of the resistor plate 42 is electrically connected to the oxygen pump 331 and the air pump 101, so as to control the operation of the air pump 101. The air pump 101 transmits the gas around the plug-in tube 3 and the connecting tube 5 to the metal tube 12 through the suction cylinder 102, and transmits the gas to the working box 9 through the metal tube 12. When the air pump 101 is working, the electromagnetic heating coil 13 is also started to work. The electromagnetic heating coil 13 heats the metal tube 12 and the gas inside the metal tube 12. When there is a laughing gas leakage accident between the plug-in tube 3 and the connecting tube 5, the gas transmitted by the suction cylinder 102 contains laughing gas, and the electromagnetic heating coil 13 will heat the laughing gas. The laughing gas will react to generate oxygen and nitrogen under high temperature conditions. The molecular formula is as follows: N2O (nitrous oxide) →N2 (nitrogen) + O2 (oxygen), and the gas density of nitrogen is less than that of oxygen, so that the upper space inside the working box 9 will be filled with nitrogen, and the nitrogen filled in the upper space will squeeze out the oxygen, while the lower space will be filled with oxygen. When the delivery pump 16 and the igniter 19 are controlled to work by the timing controller, the combustion head 18 will not be ignited due to lack of oxygen at the top, and the mercury in the container 20 will not be heated and expand to push the piston plate 23 to drive the conductive frame 24 to move. When the timing controller controls the delivery pump 16 and the igniter 19 to work, by energizing The time delay relay will delay the transmission of external current to the conductive frame 24. When the mercury does not expand due to heat, the conductive frame 24 is always in contact with the conductive block 25. The external delayed current will be transmitted to the conductive block 25 through the conductive frame 24, and the conductive block 25 is electrically connected to the electromagnetic block 262. When the electromagnetic block 262 is energized with current, magnetism will be generated, causing the electromagnetic block 262 to attract the permanent magnetic plate 30 to move upward. The permanent magnetic plate 30 drives the plug 28 and the upper electric contact plate 31 to move upward through the lifting plate 29, thereby separating the upper electric contact plate 31 from the lower electric contact plate 32.Thereby, the circuit of the normally closed electromagnetic valve 4 is disconnected. The normally closed electromagnetic valve 4 will be in a closed state after the circuit is disconnected, so as to prevent the gas in the gas cylinder 2 from continuing to leak from the plug-in tube 3. Referring to the above principle, when the plug-in tube 3 is not leaked, there will still be oxygen in the upper space inside the working box 9. When the combustion head 18 and the igniter 19 are working, the gas will be ignited, so that the mercury inside the containing tube 20 is heated. The mercury will expand after being heated, thereby pushing the piston plate 23 to drive the conductive frame 24 and the conductive block 25 to move to the right, so that the conductive frame 24 and the conductive block 25 are separated, thereby disconnecting the circuit of the electromagnetic block 262. When the delayed external current is transmitted to the conductive frame 24, the electromagnetic block 262 will not generate magnetism, and the normally closed electromagnetic valve 4 will continue to be energized to open and transmit laughing gas; When laughing gas leaks from the gas cylinder 2 and the lifting plate 29 moves upward, the lifting plate 29 will drive the metal plate 41 to move upward to a suitable position, so that a portion of the metal plate 41 contacts the upper end of the resistor plate 42, and a portion contacts the copper plate 43, and the upper end of the resistor plate 42 is electrically connected to the oxygen pump 331 and the air pump 101. When the metal plate 41 contacts the upper part of the resistor plate 42, the resistance connected to the oxygen pump 331 and the air pump 101 will be reduced. In the case of inconvenient external voltage, the current flowing into the oxygen pump 331 and the air pump 101 will increase, thereby increasing the power of the oxygen pump 331 and the air pump 101, and the air pump 101 will increase the inhalation speed to remove the laughing gas that escapes to the surrounding area. All of them are transported to the working box 9 and converted into nitrogen and oxygen, and the oxygen delivery pump 331 discharges the converted oxygen through the support pipe 332, the connecting sleeve 35, the rotating disk 36 and the gas outlet head 37, thereby increasing the oxygen content in the air in the operating room, and the leaked laughing gas and oxygen can be mixed together, thereby increasing the oxygen content in the laughing gas, avoiding the problem that the medical staff inhaling too much laughing gas will cause damage to the body, and the copper plate 43 is electrically connected to the buzzer 60. When the metal plate 41 and the copper plate 43 are in contact, an external current will be transported to the buzzer 60, so that the buzzer 60 works and alarms, reminding the personnel in the operating room that a laughing gas leakage accident has occurred and corresponding emergency measures need to be taken; When the gas cylinder 2 starts to deliver nitrous oxide, the external control button will also synchronously control the water pump 442 to work, and the water pump 442 will drive the water flow to pass through the annular tube 441. When the water flows through the annular tube 441, the heat dissipated by the electromagnetic heating coil 13 will also heat the water flow in the annular tube 441. The water flow in the annular tube 441 enters the concave cavity 45 through the connecting pipe 46, and the concave cavity 45 is connected to the heating cavity 47. The water flow heated for the first time will enter the spiral tube 50 through the heating cavity 47. When the burner head 18 is turned on, the water flow will be heated by the electromagnetic heating coil 13. When the initial work is ignited, the heat will be transferred to the heating chamber 47 through the heating plate 48, and the water in the heating chamber 47 that has been heated for the first time can be heated for the second time.
