Description

Technical Field

[0001] This invention relates to the field of medical device technology, specifically to a high-frequency ventilation device for patients with acute lung injury. Background Technology

[0002] Acute lung injury (ALI) and acute respiratory distress syndrome (ARDS) are common critical illnesses in clinical emergency care. They are often triggered by sudden factors such as severe trauma, shock, inhalation injury, and severe infection. Patients experience rapid onset and progression, and can develop severe hypoxemia and respiratory failure within a short period of time. If effective respiratory support is not provided in time, the mortality rate is extremely high. As the core carrier of pre-hospital emergency care, the ambulance must provide continuous and safe ventilation therapy for these patients during transport to buy time for further treatment in the hospital. At the same time, the continuity of respiratory support during the transfer of patients from the ambulance to the in-hospital resuscitation room directly affects the treatment outcome. Once ventilation is interrupted, the patient's condition can easily worsen and even endanger their life.

[0003] Currently, the ventilation support methods for patients with acute lung injury in pre-hospital emergency care mainly rely on conventional mechanical ventilation devices or simple respirators. However, these devices have many limitations in the application of ambulance scenarios and cannot meet the emergency needs of patients with acute lung injury and the need for seamless transfer between out-of-hospital and in-hospital care. High-frequency ventilation (HFV), employing a low tidal volume, high frequency, and low airway pressure ventilation mode, effectively reduces alveolar overexpansion caused by high tidal volume ventilation, lowers the risk of barotrauma, and rapidly improves patient oxygenation. It has become the preferred respiratory support method for patients with acute lung injury. However, when existing HFV devices are used in ambulance scenarios, the combined design with portable oxygen cylinders (gas source) and masks (airway connection) still has many technical shortcomings and cannot be simultaneously transported to the resuscitation room with the patient's bed. Specifically: Existing high-frequency ventilation devices are mostly large-scale equipment used in intensive care units. They are bulky, heavy, and complex in structure, making them unsuitable for the cramped space of ambulances. They are also inconvenient to transport, hindering emergency personnel from quickly installing, adjusting, and operating them during emergency transfers, which can delay patients' emergency care. In addition, these devices cannot move synchronously with the bed. When a patient is transferred from the ambulance to the resuscitation room, ventilation must be interrupted, the device disassembled, and then transported and reinstalled, resulting in excessively long ventilation interruptions. This seriously affects the continuity of treatment and may even worsen lung damage in patients. Summary of the Invention

[0004] Based on this, the purpose of the present invention is to provide a high-frequency ventilation device for patients with acute lung injury, so as to solve the technical problems mentioned in the background art.

[0013] like Figure 1-6 As shown, this invention provides a high-frequency ventilation device for patients with acute lung injury, suitable for pre-hospital emergency transport of patients with acute lung injury and acute respiratory distress syndrome. It enables synchronous movement of the device and the hospital bed, ensuring continuous ventilation, and simultaneously achieves lung-protective ventilation through a high-frequency, low-pressure ventilation mode. Specific embodiments are as follows: The device comprises an integrated main body 1, which integrates a motorized high-frequency ventilation drive mechanism, an integrated gas supply mechanism, an airflow buffering and stabilizing mechanism, a bed-adaptive movement mechanism, a human-machine interface control mechanism, and a power supply mechanism. The motorized high-frequency ventilation drive mechanism converts the gas source into a high-frequency, low-pressure airflow suitable for patients with acute lung injury, achieving small tidal volume protective ventilation. The integrated gas supply mechanism stores and delivers high-pressure oxygen to the ventilation drive mechanism, enabling rapid oxygen replenishment without the need for a separate oxygen cylinder. The airflow buffering and stabilizing mechanism buffers and reduces the pressure of the delivered oxygen airflow, ensuring stable ventilation pressure. The bed-adaptive movement mechanism securely connects the main body 1 to the bed, allowing the device to move synchronously with the bed and provide uninterrupted ventilation throughout the entire process. The human-machine interface control mechanism controls the start / stop and parameter adjustment of the ventilation drive mechanism and displays the device's operating status. The power supply mechanism provides power to all electrical components of the device. The motorized high-frequency ventilation drive mechanism includes a voice coil motor module 2, a housing 5, and a diaphragm 6. The housing 5 forms a closed airflow drive cavity inside the main body 1. The output end of the voice coil motor module 2 is axially inserted through the side wall of the housing 5 and is connected to the center of the diaphragm 6. When the voice coil motor module 2 is powered on, it can drive the diaphragm 6 to perform high-frequency reciprocating motion in the airflow drive cavity of the housing 5. The airflow is drawn in and out through the change of cavity volume, providing high-frequency ventilation power for the patient. The airflow buffer and pressure stabilizing mechanism includes an annular buffer cylinder 4, a first air pipe 9, and a second air pipe 10. The annular buffer cylinder 4 is connected to the airflow driving chamber of the housing 5. One end of the first air pipe 9 is connected to the air outlet of the annular buffer cylinder 4, and the other end extends into the housing 5 and communicates with the airflow driving chamber. One end of the second air pipe 10 is connected to the airflow driving chamber of the housing 5, and the other end passes through the side wall of the main body 1 and extends outward for connecting to an external ventilation pipe and an oxygen mask. One-way valves are embedded inside the first air pipe 9 and the second air pipe 10. The ventilation directions of the two one-way valves are matched to realize the one-way delivery of oxygen airflow from the annular buffer cylinder 4 to the housing 5, and then from the housing 5 to the second air pipe 10. The annular buffer cylinder 4 is also provided with a buffer ring 8. The buffer ring 8 has a conical structure, which can buffer and reduce the pressure of the high-pressure oxygen delivered by the integrated gas source supply mechanism, and at the same time weaken the pressure impact during the airflow delivery process to ensure the pressure stability of the subsequent ventilation airflow. The integrated gas supply mechanism includes an annular compressed oxygen cylinder 3 and a valve assembly 7. The annular compressed oxygen cylinder 3 is a sealed high-pressure oxygen storage structure, and its outlet end is connected to the input end of the valve assembly 7. The output end of the valve assembly 7 is connected to the air inlet of the annular buffer cylinder 4. The gas supply between the annular compressed oxygen cylinder 3 and the annular buffer cylinder 4 can be controlled by opening and closing the valve assembly 7. A quick connector 11 is provided on one side of the bottom of the annular compressed oxygen cylinder 3. The quick connector 11 is connected to the inside of the annular compressed oxygen cylinder 3. Compressed oxygen can be quickly filled into the annular compressed oxygen cylinder 3 through the quick connector 11, eliminating the need to carry an additional separate oxygen cylinder component and realizing the integrated integration of the gas source and the device. The bed-adaptive moving mechanism consists of two sets of identical connecting hangers 16. The two sets of connecting hangers 16 are symmetrically fixed on the outer side wall of the main body 1. The connecting hangers 16 can be used with connecting ropes or connecting rods to hang and fix the main body 1 as a whole on the guardrail of the ambulance bed or the resuscitation room bed, so as to realize the synchronous movement of the device and the bed. The device does not need to be disassembled during the patient transfer, ensuring uninterrupted ventilation throughout the process. The human-machine interface control mechanism is a display control module 14, which is embedded on the outer surface of the main body 1 and electrically connected to the voice coil motor module 2. The display control module 14 can control the start and stop of the voice coil motor module 2, and can also adjust the working parameters of the voice coil motor module 2, thereby controlling the high-frequency reciprocating motion frequency of the diaphragm 6 to adapt to the ventilation needs of different patients. The display control module 14 can also display the ventilation frequency, airway pressure and the remaining gas supply in the annular compressed oxygen cylinder 3 in real time, so that emergency personnel can keep track of the device's working status in real time. The power supply mechanism is a battery module 13, which is built into the bottom cavity of the main body 1 and is electrically connected to the voice coil motor module 2 and the display control module 14, providing stable power support for the electrical components of the entire device. The bottom of the main body 1 is also fixed with a base frame 12, which supports the main body 1 and the internal battery module 13, and enhances the stability of the main body 1 when placed on a flat surface, preventing the device from tipping over and being damaged. The outer side of the main body 1 is also covered by a protective cover 15, which is correspondingly covered on the outer side of the shell 5. It protects the shell 5 and the internal precision components such as the diaphragm 6 and the airflow drive cavity, and plays a role in dust prevention and collision prevention. It avoids damage to the device components by external force impact during emergency transport and ensures the normal operation of the device.

[0014] The working principle of this invention is as follows: When in use, the main body 1 can be connected to the hospital bed through two sets of connecting hangers 16. Specifically, the main body 1 can be hung on the hospital bed using additional connecting ropes or connecting rods, and can move with the hospital bed. When in use, one end of the ventilation pipe is connected to the second air pipe 10, and the other end is connected to the oxygen mask and the patient's face. At this time, manually open the valve assembly 7 to connect the annular compressed oxygen cylinder 3 and the annular buffer cylinder 4, start the voice coil motor module 2. The output end of the voice coil motor module 2 can pass through the inside of the shell 5 to drive the diaphragm 6 to reciprocate. Specifically, when the diaphragm 6 rises, the volume of the cavity below the diaphragm 6 inside the shell 5 increases, thereby drawing oxygen from the annular buffer cylinder 4 through the first air pipe 9. At this time, the first air pipe 9 is equipped with a one-way valve, which can only allow air to pass in one direction. When the diaphragm 6 descends, the oxygen in the cavity below the diaphragm 6 inside the shell 5 will be discharged through the second trachea 10. At this time, the second trachea 10 is also equipped with a one-way valve. The oxygen discharged through the second trachea 10 will enter the oxygen mask through the ventilation tube, thereby providing oxygen supply and assisting breathing for the patient. Furthermore, the annular compressed oxygen cylinder 3 has a quick connector 11 on one side of the bottom, which allows compressed oxygen to be filled into the annular compressed oxygen cylinder 3 in advance through the quick connector 11, eliminating the need to carry additional oxygen cylinder components, thereby reducing the overall weight and improving overall convenience. In summary, by setting the connecting bracket 16 on the main body 1, the device can be directly hung and fixed to the hospital bed without the need for additional complex fixing structures. It can be moved out of the ambulance and transported to the hospital emergency room simultaneously with the ambulance and hospital bed, without the need to disassemble the device or interrupt ventilation throughout the process. This completely solves the problem that existing large high-frequency ventilation devices cannot be moved synchronously with the hospital bed, and that disassembly and reassembly are required during patient transport, which leads to ventilation interruption and aggravation of lung injury. It buys critical time for pre-hospital emergency care and in-hospital treatment of patients with acute lung injury, greatly reduces the risk of disease deterioration caused by ventilation interruption, and improves the overall success rate of treatment. Meanwhile, it abandons the redundant structure of existing high-frequency ventilation devices and adopts an integrated design to integrate the ventilation core components and gas source components into a single body. It also features a ring-shaped compressed oxygen cylinder 3 structure, which can be directly filled with compressed oxygen through quick connector 11, eliminating the need to carry separate oxygen cylinder components, thus significantly reducing the overall weight and volume of the device. At the same time, the device has a compact overall structure and does not require complicated installation and debugging procedures, making it easy for emergency personnel to quickly deploy and operate in the confined space of an ambulance. This solves the problems of existing devices being bulky, inconvenient to transport, and having poor adaptability, meeting the core needs of pre-hospital emergency care to "race against time". The voice coil motor module 2 drives the diaphragm 6 to perform high-frequency reciprocating motion. Combined with the one-way valve structure in the first trachea 9 and the second trachea 10, high-frequency airflow delivery is achieved. At the same time, the annular buffer cylinder 4 buffers and stabilizes the airflow, ensuring low airway pressure during ventilation. This effectively reduces alveolar overexpansion caused by large-volume ventilation and lowers the risk of barotrauma and collapse injury. The ventilation mode of the device perfectly meets the lung protection needs of patients with acute lung injury, can quickly improve patients' hypoxemia, and avoid further damage to damaged lung tissue caused by mechanical ventilation, thus improving the safety and effectiveness of pre-hospital emergency ventilation therapy.
