Detailed Description

The invention mainly provides a system of a high-frequency respirator, and explains the working principle of the high-frequency respirator, and does not explain an unconventional ventilation method and an early warning method.
In addition, the directional descriptions of "between" and "between" mentioned in the embodiments of the present invention do not mean between and among the structures, but between and among the gas path relations, and the structures related to the mutual communication are communicated through the pipeline, and furthermore, the descriptions of the words "first" and "second" in the text do not constitute a limitation on the specific number, but are not construed as a limitation on the present invention for the convenience of understanding the simplified description and the distinction of the present invention.
The present invention will be described in detail below with reference to the accompanying drawings in conjunction with embodiments.
The embodiment provides a high-frequency breathing machine system, which comprises a turbo fan 11, a compressed oxygen source 15, a mixing chamber 14, an inspiration circuit and a high-frequency oscillation module 5, wherein the turbo fan 11 and the compressed oxygen source 15 are respectively communicated with the mixing chamber 14, and the mixing chamber 14 is also communicated with the inspiration circuit; the high-frequency oscillation module 5 is positioned in the inspiration circuit and is suitable for generating oscillation pressure waves for the gas in the inspiration circuit.
The air source and the compressed oxygen source 15 are respectively communicated with an inlet of the mixing chamber 14, and the suction circuit is communicated with an outlet of the mixing chamber 14. Here, a second stop valve 13 is provided between the turbo fan 11 and the mixing chamber 14, and the gas sent from the turbo fan 11 to the mixing chamber 14 is controlled by the second stop valve 13, thereby reducing the risk. A pressure reducing valve 16 is arranged between the compressed oxygen source and the mixing chamber and is used for adjusting the delivery quantity of the compressed oxygen. Furthermore, a pressure-flow sensor 12 is provided between the turbo fan 11 and the mixing chamber 14, and monitors the gas delivered by the turbo fan 11 to the mixing chamber 14.
Here, when the air flows into the patient end, the air and the compressed oxygen are mixed in the mixing chamber 14, and then the mixed gas is delivered to the patient end, on one hand, disturbance of the compressed gas of the turbo fan 11 can be reduced, and a slow flow effect can be achieved, on the other hand, the air and the compressed oxygen are mixed in the mixing chamber 14, so that the distribution of the gas is more even, and in addition, when the temperature of the air delivered by the turbo fan 11 is higher, the compressed oxygen can also absorb the heat of the air delivered by the turbo fan 11.
When the concentration of oxygen to be delivered is lower than 100%, the turbo fan 11 is used for compressing and delivering air to the mixing chamber to mix the air and the compressed oxygen, and the turbo fan 11 provides power for the mixed air to deliver the air to the patient end. When pure oxygen is needed at the patient end, at the moment, the compressed oxygen is decompressed through the decompression valve 16 and then is sent into the air suction loop, one end of the turbo fan 11 communicated with the air is closed, and the delivery turbo fan 11 generates high-pressure airflow at the moment and is used for delivering the oxygen. The high-frequency ventilator system also comprises a filter 19, located between the turbo fan 11 and the mixing chamber 14, adapted to filter the air delivered by the turbo fan 11. On the one hand, impurities in the gas delivered by the turbo fan 11 can be filtered, and on the other hand, the gas delivered by the turbo fan 11 can be subjected to slow flow, so that disturbance of the gas after passing through the filter 19 is reduced. Of course, the filter 19 can also be arranged at the air inlet, i.e. before the turbo fan 11.
Here, the high frequency oscillation module includes an actuator, a piston, and a diaphragm, the diaphragm being disposed on the piston, the actuator driving the piston to reciprocate linearly, thereby generating positive and negative pressure waves in the gas. When the gas delivered by the turbo fan 11 flows to the high-frequency oscillation module 5, the high-frequency oscillation module 5 drives the diaphragm to reciprocate through the actuator, so that oscillation pressure waves are generated in the gas. Here, the amplitude of the HF oscillation module is at most 100mbar and the ventilation frequency is 3-20 Hz. The advantage of this arrangement is that the use of the turbo fan 11 in conjunction with the hf oscillation module 5 replaces the usual compressed air with air which is pressurized by the turbo fan and delivered to the patient side without the use of a compressed air source.
In general, there may be disturbances in the gas delivered by the turbo fan 11, and there may also be disturbances in the upstream gas path by the high frequency oscillation module 5. As shown in fig. 1, the high-frequency ventilator system further includes a proportional valve 2 located in the inspiration circuit and located between the high-frequency oscillation module 5 and the mixing chamber 14, and the gas in the mixing chamber 14 flows to the high-frequency oscillation module 5 through the proportional valve 2. It should be noted that, when the gas flowing out from the mixing chamber 14 flows to the high-frequency oscillation module 5, the gas passes through the proportional valve 2, and then the flow rate and the pressure flowing to the high-frequency oscillation module 5 are adjusted by the proportional valve 2, and by the arrangement of the proportional valve 2, on one hand, the disturbance of the gas delivered by the turbo fan 11 can be reduced, and on the other hand, the pressure and the flow rate of the gas delivered to the high-frequency oscillation module 5 can be adjusted.
In addition, since the turbo fan may generate a negative pressure to cause gas backflow, the high frequency ventilator system further includes a check valve 17 disposed between the mixing chamber 14 and the proportional valve 2 for preventing gas in the inhalation circuit from flowing back into the mixing chamber 14. Through the arrangement of the check valve, the interference of the high-frequency oscillation unit on the air path upstream of the proportional valve is also avoided.
Since the flow rate of the gas delivered by the turbo fan 11 is not controllable, the frequency at which the high-frequency oscillation module 5 operates is related to the pressure and flow rate of the gas flowing into the high-frequency oscillation module 5. As shown in fig. 1, the high-frequency ventilator system further comprises a first pressure-flow sensor 18, located in the inspiratory circuit between the mixing chamber 14 and the proportional valve 2, adapted to detect the pressure and flow of the gas flowing out of the mixing chamber 14. That is, when the gas flows out of the mixing chamber 14, the flow rate and pressure of the gas flowing out of the mixing chamber are monitored, and then the adjustment of the proportional valve 2 is guided, so that the pressure and flow rate of the gas flowing out of the proportional valve 2 meet the preliminary requirements of the high-frequency oscillation module 5, and the breathing experience of the patient is increased.
At this time, in order to ensure accuracy of the pressure and flow rate of the gas flowing into the hf oscillation module 5, the hf ventilator system further includes a second pressure and flow rate sensor 4, located in the inspiratory circuit and between the hf oscillation module 5 and the proportional valve 2, adapted to detect the pressure and flow rate of the gas flowing into the hf oscillation module 5. That is, before the gas flows into the high-frequency oscillation module 5, the flow rate and the pressure of the gas are monitored, the result is fed back to the controller, and the opening degree of the proportional valve 2 is further adjusted by the controller, so that the accuracy of the pressure and the flow rate of the gas flowing into the high-frequency oscillation module is ensured.
It should be noted that the high frequency ventilator system further comprises an oxygen concentration sensor 21, which is located in the inspiratory circuit and is adapted to monitor the oxygen concentration in the inspiratory circuit. That is, before the gas is delivered to the patient, the oxygen concentration in the inspiratory circuit is monitored and timely fed back to the controller, and the compressed oxygen source is timely adjusted so that the oxygen concentration delivered to the patient is closer to the optimal value.
Since the temperature of the turbo fan 11 increases gradually as the turbo fan 11 delivers the gas, the temperature of the gas flowing in through the turbo fan 11 increases, and the temperature of the gas flowing out of the mixing chamber 14 is measured even as high as 51 ℃ due to the operation of the turbo fan 11. In this case, a refrigerator is provided in the mixing chamber 14, adapted to cool the gas in the mixing chamber 14. It should be noted that the refrigerator may be a semiconductor refrigerator, and the refrigerator may also be a cooling fan.
In addition, the high frequency ventilator system further comprises a temperature sensor 9, located in the inspiratory circuit, between the patient side and the mixing chamber 14, adapted to monitor the temperature of the gas in the inspiratory circuit. Here, the gas temperature is monitored in real time and transmitted to the controller, and when the gas temperature in the suction circuit is higher than a set value, the operation power of the refrigerator is increased or the oxygen supply amount of the compressed oxygen source is increased.
Since the gas delivered by the turbo fan 11 is not controllable, in order to reduce the risk, the hf ventilator system further comprises a safety valve 3, the safety valve 3 being located in the inspiratory circuit. In an emergency, the air suction circuit is connected to the atmosphere, so that the air delivered by the turbo fan 11 is discharged directly into the air.
Furthermore, the high-frequency ventilator system comprises an expiratory circuit for the discharge of the gas exhaled by the patient, the outlet of which is provided with a breather valve 8. In order to further enhance the safety performance, the high frequency ventilator system further comprises a safety circuit which communicates the inspiration circuit with the expiration circuit, the safety circuit being provided with a first shut-off valve 10. The first stop valve 10 is opened when the inhaled gas is abnormal (usually, the gas flow or the pressure is too large), the breather valve 8 is opened at the same time, so that a part of the gas is exhausted out of the room, and the one-way valve 7 is arranged in the expiration loop, so that only the gas is expired from the expiration loop, and the gas is prevented from supplying gas to the patient from the expiration loop. The opening degree of the first stop valve 10 is required to ensure sufficient gas supply for the patient.
Here, the inlet of the safety circuit is located between the proportional valve 2 and the high-frequency oscillation module, that is, the communication between the safety circuit and the inhalation circuit is located upstream of the high-frequency oscillation module 5, the high-frequency ventilator system further includes a check valve 20 disposed in the inhalation circuit and located between the high-frequency oscillation module and the patient side, the check valve 20 is a one-way valve adapted to allow the gas to pass through to the patient side, and prevent the exhaled gas of the patient from flowing back from the check valve 20.
In addition, the high frequency ventilator system further comprises a third pressure flow sensor 6, commonly referred to as a patient (proximal) flow (pressure) sensor, disposed at the patient's end, adapted to monitor the pressure and flow of gases inhaled and exhaled by the patient, typically, the third pressure flow sensor 6 is adapted to monitor the mean airway pressure of the patient. Here, the third pressure-flow sensor 6 is arranged between the patient end and the intersection of the inspiratory circuit and the expiratory circuit.
It should be noted that, when the high-frequency breathing machine system ventilates at a constant frequency, the high-frequency oscillation module is closed, the turbofan is started, and the timing and quantitative air supply is realized by controlling the ventilation time and the valve in the air passage; when high-frequency ventilation is carried out, a continuous basic airflow is provided through the turbo fan, so that the stability of the average airway pressure of a patient end is guaranteed, the high-frequency oscillation module is started, the amplitude and the frequency of the high-frequency oscillation module are set, and the high-frequency oscillation ventilation is realized through the cooperation of the high-frequency oscillation module.
In the embodiments, only the pneumatic circuit of the high frequency ventilator system is illustrated. The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that are within the spirit and principle of the present invention will be apparent to those skilled in the art from this description.
