Description

APPARATUS OF ART LUNG VENTILATION.
The utility model relates to medicine and can be used in anesthesiology, resuscitation and intensive therapy in violation of the normal tension of oxygen and carbon dioxide in arterial blood, in violation of external respiration, leading to a decrease in the functional capabilities of the body.
Known artificial lung ventilation (mechanical ventilation) type RO-6, designed for long-term mechanical ventilation in the intensive care unit and intensive care unit. (VL Kassil. Artificial ventilation of the lungs in intensive care. M. "Medicine. 1987, p. 81-84). The known apparatus contains hoses for supplying air and oxygen, rotameters, a rubber bag and fur with hoses for supplying the respiratory mixture to the inhalation line, an additional inhalation valve, a humidifier and a heater for inhaled air and an exhalation line. The device allows for mechanical ventilation. To ensure a smooth transition to independent breathing. The device has calibrated scales for setting the tidal volume, minute ventilation, the ratio of the duration of inspiration and expiration. Controlled parameters also include airway pressure.
The disadvantages of the known ventilator should include a limited number of monitored parameters, the lack of automatic control and display of information, which reduces the efficiency of the use of devices of this type in clinical practice.
Known ventilator apparatus containing a flow generator, a source of compressed oxygen, a gas distribution device with a sensor
A61H 31/02
oxygen and humidifier, a tee with inhalation and expiration lines of the patient and a control system with pressure and flow rate sensors in the upper respiratory tract and a flow rate sensor in the exhalation line. (Application for invention No. 98123961/14, class 7A61H 31/02, published in 2000). The well-known ventilation device monitors the oxygen content in the air stream and allows you to automatically adjust such parameters as pressure and flow rate, parameters derived from them (respiratory rate, etc.).
The disadvantages of this apparatus include the limited amount of information obtained in the process of its functioning, which reduces the ability to monitor the patient’s lung condition during mechanical ventilation and timely changes to the set parameters of the apparatus in
compliance with the patient's condition. In addition, the device does not provide control over deviation from the set parameters.
A ventilator apparatus is proposed comprising a flow generator, a source of compressed oxygen, a gas distribution device, an inspiratory line with an inspiratory valve connected to a gas distribution device, an exhalation line with an exhalation valve connected to the atmosphere, a patient line, and a control system with pressure and flow rate sensors installed in inspiratory lines, and pressure and flow rate sensors installed in the exhalation line.
The difference is that the device is equipped with a graphic monitor with a processor and inspiratory and expiratory volume sensors installed respectively in the inspiratory and vshokha lines. Sensors installed in the inspiration line are connected to the first input of the control system and to the first input of the processor. Sensors installed in the exhalation line are connected to the second input of the control system and to the second input of the processor. The processor output is connected to the graphic monitor input.
The advantage of the proposed design of the ventilator apparatus is the expansion of the amount of information about the apparatus and the condition of the patient’s lungs, which allows you to quickly adjust the parameters of RVL, increase its effectiveness and reduce the complications that arise during the IVV process.
The essence of the utility model is illustrated in the drawing, which shows a schematic block diagram of a ventilator.
The apparatus contains a flow generator 1, a biased oxygen source 2, a gas separation device 3, a tee 4, a control system 5 and a graphics computer 6 with a processor 7. A fan is used as a flow generator, and an oxygen cylinder can be used as a source of compressed oxygen. The flow generator 1 and the compressed oxygen source 2 are connected to a gas distribution device 3, which may include a flow regulator, an oxygen sensor, and a flow humidifier. A tee 4 is connected to the outlet of the gas distribution device, comprising an inspiratory line 8 with an inspiratory valve 9, which is connected to the gas distribution device, an exhalation line 10 with an exhalation valve 11 connected to the atmosphere, and a patient line 12. Pressure sensors in the upper respiratory tract are installed in the inspiratory line 13 , inspiratory flow rate 14 and inspiratory volume 15. These sensors are connected in parallel to the first inputs of the control system 5 and processor 7. An exhalation flow rate sensor 16, an exhalation volume sensor 17, and dates are installed in the expiration line expiratory pressure sensor 18. These sensors are connected in parallel to the second inputs of the control system and the processor.
Below is a description of the operation of the ventilator.
in the presence of indications for the patient's ventilation, after appropriate preparation and selection of the ventilation parameters, they are connected to the device by a known method. Air and oxygen from the flow generator 1 and the compressed oxygen source 2 are supplied to the gas distribution device 3, where the mixture components are mixed in a predetermined ratio, heated and moistened. The parameters of the gas-air flow and the operation mode of the valves 9, 11 are set and automatically controlled using the control system 5 connected to the gas distribution device. The gas stream enters the inspiration line and, under the influence of the pressure difference, moves into the patient’s alveoli. The movement of the flow into the alveoli is mainly counteracted by the resistance of two types: elastic and aerodynamic. The elastic properties are inherent in lung tissue and chest. Under the action of the tensile force created by the flow, the tissues change their length or volume, and after the termination of the action of this force, they return to their original position
Aerodynamic drag is determined by the friction of the flow on the walls of the respiratory tract. The outgoing stream enters from the patient line 12 to the exhalation line 10 and is discharged into the atmosphere through the exhalation valve 11. In the process of mechanical ventilation, data from sensors 13,14,15 of the inspiration line and sensors 16,17,18 of the exhalation line are sent to different inputs of the processor 7, where they are processed, and graphical dependencies are displayed on the screen of the graphic monitor:
- graph of pressure versus time - P inspiration f (t) - graph of flow rate versus time - V (noTOKa) f (t) - graph of inspiratory volume versus time - V (o6beM) f (t) - graph of inspiratory pressure on inspiratory volume - P inspiratory (V) -the graph of the dependence of the flow velocity on the volume of voxa-V (flow) f (V)
A & i (& pii o
The graphic monitor constantly gives such indicators of the IV L process as: inspiratory pressure, tidal volume, respiratory rate, minute volumetric ventilation, compliance, aerodynamic resistance (resistens).
At the same time, the indicators of all the sensors enter the control system 5, where they are analyzed and, in the event that any indicator deviates from the control, the system gives a signal to the operator. Graphic and digital information on the screen of the graphic monitor allows the operator to determine the nature of the discrepancy between the adopted ventilation mode and etiology of the patient’s respiratory failure and take the necessary measures to correct it.
The introduction of a graphic monitor into the ventilation device design allows to significantly increase the volume of operational information about the ventilation process, to increase the monitoring efficiency and its safety.
