Description

Portable anesthesia machine based on oxygen self-sufficiency

Technical field:

The invention relates to an anesthesia machine, in particular to a portable anesthesia machine based on oxygen self-sufficiency. It belongs to the technical field of medical equipment.

Background technique:

At present, most anesthesia machines use compressed gas cylinders to supply oxygen, which cannot achieve oxygen self-sufficiency. Because oxygen is an explosive gas, the use of gas cylinders for oxygen supply has the disadvantages of inconvenient transportation and portability. At the same time, the oxygen supply of gas cylinders is extremely limited, which cannot meet the continuous oxygen supply requirements of the anesthesia respiratory system, especially in the field or where disasters occur. The problem is particularly prominent in environments where there are many inconveniences. However, the oxygen generator in the prior art cannot satisfy the seamless connection with the respiratory system technically and physically. In addition, the transportation of oxygen is strictly limited, therefore, the oxygen supply of cylinders also has the defect of small scope of application. Aiming at the defects of the central oxygen supply system and compressed gas cylinders, some people use micro-oxygen generators to supply oxygen. However, due to the unreasonable structure of the micro-oxygen generators currently in use, the pressure provided by them is generally below 0.07Mpa and the flow rate Below 5L/min, the air pressure is low and the flow rate is low. When the oxygen source supported by a ventilator or anesthesia machine requires a flow rate of 10L/min, an instantaneous oxygen flow rate of 35L/min, and a pressure of 0.19Mpa or more, the micro The oxygen concentrator cannot meet the needs. How to solve the contradiction between the two in the existing micro is a difficult point to be solved in this project. There are also some oxygen supply equipment that are bulky (740mm×332mm×790mm) and heavy (74kg), and there are defects such as unstable flow rate, slow oxygen output, rough oxygen concentration display, loud noise, and complicated operation during use. Therefore, it is necessary to develop a highly integrated portable high-pressure oxygen equipment with stable performance, safety and reliability, and a design idea that is separated from the existing traditional design mode.

Working principle of the present invention:

The working principle of the anesthesia device: the oxygen provided by the oxygen source device directly enters the anesthesia device in three ways, and various breathing modes are set through the controller.

1) In the machine control mode, when inhaling, the PEEP valve is closed, and the gas delivered by the oxygen source device is compressed into the folding bag in the bellows, and the gas in the bellows will pass through the manual/machine control switch, the absorption tank and the inhalation unit in sequence. Direct delivery to the patient through the directional valve; when exhaling, the PEEP valve is opened, and the gas exhaled by the patient passes through the one-way valve and returns to the folded bag in the bellows cover, and the excess gas is directly discharged to the AGSS system through the PEEP valve. During the inhalation process, the absorption tank filters the exhaled carbon dioxide and provides it to the patient together with the fresh gas delivered by the flow meter.

2) In the manual mode, when inhaling, the gas is directly delivered to the patient through the manual/machine control switch, the absorption tank and the inhalation one-way valve by pinching the skin bag; when exhaling, the gas exhaled by the patient passes through the one-way valve After returning to the bladder, the excess gas is directly discharged to the AGSS system through the APL valve. During the inhalation process, the absorption tank filters the exhaled carbon dioxide and provides it to the patient together with the fresh gas delivered by the flow meter. In manual mode, rapid oxygenation is required.

3) When working, the oxygen provided by the oxygen source device directly enters the oxygen input port. After setting various ventilation modes through the controller, when inhaling, the ventilator will deliver the gas to the patient through the circuit according to the instruction; when exhaling, the patient Exhaled air is circulated by the patient circuit back into the bellows bellows pocket and expelled. The airway pressure gauge monitors the patient's breathing pressure in real time; the flow meter can quantitatively deliver anesthetics to the patient, and various human body parameters are monitored and fed back by the controller.

The working principle of the oxygen source device: the turbine compressor is controlled by the PLC controller, and the air extracted by the turbine is processed by the air filter module (including filter and muffler) to reach a certain pressure, and then the compressed air is cooled by the cooler Cooling treatment, directly enters the molecular sieve bed through the control of the solenoid valve, and the oxygen from the molecular sieve meets and directly enters the oxygen storage tank to maintain a certain capacity and pressure, and finally adjusts the pressure to the anesthesia device through the pressure regulating valve. Among them, the turbo compressor and solenoid valve are controlled by programmable logic control technology, and the solenoid valve and turbocharger are adjusted according to the feedback of oxygen concentration, pressure, and flow rate from the operating status display module. A safety relief valve is installed after the turbo compressor, and an overpressure alarm device is installed behind the oxygen storage tank, and feedback is given through the operating status display module to prevent damage to pipelines and equipment due to excessive pressure. These alarm and protection devices include mechanical devices such as safety valves and exhaust mufflers.
