Anaesthetic and respiratory apparatus
Ather 6 D
Anesthesia machine is an automatic pneumatic device with electronic control which allows for a variety of respiratory support options. The device is designed for inhalation anesthesia, artificial ventilation during anesthesia for adult patients or children.
Anesthesia machine Ather 6D has the following features:
- total number of gases: 3
- mechanical flowmeter unit: two flowmeters for each gas
- protection against hypoxic mixture
- large LCD display
- using 2 vaporizers with the possibility of switching off each of the breathing circuit
- pneumatic drive
- monitoring of respiratory parameters
The Ather 6D anaesthetic and respiratory apparatus is designed for performing inhalation anesthesia in the operating room for adult patients and children with a body weight over 5 kilograms. The device can operate with low and minimal gas flows.
It has a built-in display showing the parameters of ventilation, respiratory monitoring and basic settings. Its interface is configured using membrane keys and a manipulator. Ather 6D has a built-in automatic leak compensation system, an electronic PEEP valve and mechanical flowmeters. It can be mounted and also use two evaporators.
The device uses vaporizers of inhaled anesthetics that are compatible with the lockable «Selectatec» mount. It can work sequentially with two evaporators, using liquid inhalation agents: halothane, isoflurane, sevoflurane.
Working with the device can be made more convenient by using a built-in illumination of the working field.
The gas supply to the anesthesia and respiratory apparatus is carried out from high-pressure sources (centralized wiring or an autonomous source). The gas supply is important for ensuring the operation of the pneumatic actuator. Three gases are used for the operation of the device: oxygen, air and nitrous oxide.
Mechanical flowmeters are designed to regulate the amount of gas flow supplied to the patient. Each flowmeter is designed for a certain type of gas and has two tubes. The functioning of the oxygen and nitrous oxide flow control knobs is interconnected, which prevents the assignment of a hypoxic mixture to a patient. An emergency oxygen supply button is provided.
The respiratory system module consists of the following units: a respiratory system itself, a carbon dioxide absorber, a membrane box, a pressure gauge that controls the pressure in the respiratory tract. Switching the device to the «spontaneous breathing/manual ventilation» and «automatic ventilation» modes is carried out using a special switch. The pressure level in the patient's airways in the mode of spontaneous and manual ventilation can be adjusted via the APL valve.
The anaesthetic ventilator is operated by an electronically controlled pneumatic actuator, which allows the use of various lung ventilation modes. In particular, the following modes are available: the volume-controlled mode (VCV), the pressure-controlled mode (PCV), intermittent forced ventilation with volume control (vSIMV), intermittent forced ventilation with pressure control (pSIMV), pressure support (PSV), optional spontaneous breathing (SPONT) and pressure-controlled ventilation with volume control (PRVC). All mode settings can be seen on the display, which also provides the representation of graphical parameters of a particular ventilation method in real time.
When the anesthesia device is turned on, the start screen appears, where you can select the patient's category (adult or child), set his weight, select the ventilator mode, start the operating mode or reset all the default settings.
The main screen appears when the operating mode is started. You can see the set and measured parameter values on it.
The Ather 6D anaesthetic and respiratory apparatus is equipped with built-in rechargeable lithium batteries that ensure uninterrupted operation when the external power is turned off. The batteries are charged when connected to the AC network in the switched-on state. If there is no power from the mains, the device automatically switches to battery power, notifying the user about this.
