Description

Technical Field

[0001] This utility model relates to the field of ventilator technology, and in particular to an integrated airway control module for use in a miniature pneumatic ventilator. Background Technology

[0002] Most ventilators currently on the market use a distributed airway control system, with each functional module set up independently. This configuration results in bulky and heavy equipment, making rapid deployment to the rescue site difficult in emergencies. Furthermore, its operation is complex, requiring professional personnel for operation and maintenance.

[0003] Conventional integrated solutions rely excessively on electronically controlled valve assemblies, which leads to a series of problems such as high energy consumption, poor vibration resistance, and sensitivity to electromagnetic interference.

[0004] Mechanical ventilators generally suffer from limited functionality (such as only having positive pressure ventilation) and insufficient adjustment precision, making it difficult to simultaneously meet the precise adjustment requirements of multiple parameters such as respiratory rate control, flow control, and synchronized breathing. Utility Model Content

[0005] In order to overcome the shortcomings of the prior art, this application proposes an integrated airway control module for a miniature pneumatic ventilator to solve the problems existing in the prior art.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0007] An integrated airway control module for a miniature pneumatic ventilator includes an air source interface, an integrated airway control module, and a combined valve body. The air source interface is located on one side of the miniature pneumatic ventilator housing and is directly connected to the air inlet of the airway valve body. The integrated airway control module is installed in the center inside the miniature pneumatic ventilator housing. One end of the module is connected to the airway valve body, and the other end is connected to one end of the breathing tube of the combined valve body through an internal microchannel. The other end of the breathing tube is connected to the mask interface, forming a gas delivery path.

[0008] As a further technical solution of this utility model: the gas path control integrated module includes a pressure regulating unit, a conventional switch, a manual switch, a frequency generator, a frequency control unit, a flow control unit, and a one-way device.

[0009] As a further technical solution of this utility model: the ventilator shell is also provided with control buttons and adjustment knobs.

[0010] As a further technical solution of this utility model: the one-way device is a backflow preventer.

[0011] As a further technical solution of this utility model: the breathing tube includes a negative pressure suction device, a synchronous breathing device, an air-oxygen combination device, a negative pressure safety device, and a positive pressure safety device.

[0012] One or more technical solutions provided in the embodiments of this application have at least the following technical effects or advantages:

[0013] This utility model adopts the above solution.

[0014] 1. Integrating multiple gas path control functions into a single module reduces the number of connecting pipes between components, lowers the risk of leakage, saves space, and improves system compactness.

[0017] Figure 1 This is a system diagram of this utility model. Detailed Implementation

[0018] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0019] like Figure 1 As shown, an integrated airway control module for a miniature pneumatic ventilator is presented. This module, a core component of the miniature pneumatic ventilator, integrates multiple airway control functions. Manufactured using advanced CNC machining technology, it achieves precise airway connection and efficient control through a precision microchannel design. It mainly consists of airway valve bodies and combination valve bodies.

[0020] The pneumatic valve body integrates pressure regulation, conventional switch, manual emergency switch, frequency regulation, flow regulation, and one-way backflow prevention function. By optimizing the valve core and valve seat design, it improves control accuracy and response speed, and achieves flexible function switching through the internal mechanical linkage structure.

[0021] The combined valve body integrates negative pressure suction, air-oxygen mixing, positive pressure safety, negative pressure safety, and synchronized breathing functions to ensure safe and stable airway pressure, achieve synchronization between the ventilator and the patient's spontaneous breathing, and improve the comfort and effectiveness of respiratory support.

[0022] The air source interface is located on one side of the shell of the miniature pneumatic ventilator and is directly connected to the air inlet of the air circuit valve body, ensuring that the external air source can smoothly enter the device.

[0023] The airway control integrated module is installed in the center of the miniature pneumatic ventilator's housing. This layout facilitates uniform airway distribution and efficient connection. The module is connected to one end of the breathing tubing of the combined valve body via an internal microchannel, while the other end of the breathing tubing is connected to the mask interface, thus forming a complete gas delivery path.

[0024] The control buttons and adjustment knobs are located in easily accessible positions on the surface of the miniature pneumatic respirator, allowing rescuers to quickly and accurately set parameters and operate the device in emergency situations.

[0025] The working principle is as follows:

[0026] After the gas from the external gas source enters the gas path control integrated module, it first passes through the pressure regulation unit of the gas path valve body to stabilize the gas pressure, laying the foundation for subsequent precise control of gas parameters. A conventional switch and a manual switch control the on / off state of the gas path. The frequency control unit generates pulse signals through a frequency generator based on a preset respiratory rate, driving the frequency control unit to control the number of gas on / off cycles, thereby regulating the respiratory rate. A one-way backflow prevention function, through its unique structural design, effectively prevents gas backflow. The flow control unit precisely adjusts the gas flow rate entering the gas path according to the set flow rate value. The negative pressure suction function activates when needed, generating negative pressure through a vacuum generator to assist in expelling secretions from the patient's respiratory tract. Positive and negative pressure safety devices monitor the gas path pressure in real time; if abnormal pressure is detected, they automatically activate to release excessive pressure. The synchronized breathing device detects the patient's respiratory signals, achieving synchronization between the ventilator and the patient's spontaneous breathing. The air-oxygen mixing device precisely adjusts the oxygen and air intake ratio according to a preset oxygen concentration, achieving precise air-oxygen mixing within the gas mixing chamber. The mixed gas is delivered to the mask port through the gas delivery tube to provide respiratory support to the patient.

[0027] The work process is as follows:

[0028] 1. Initial Preparation Phase: Reliably connect the ventilator's gas supply interface to an external gas source (such as an oxygen cylinder or air compressor), and connect a suitable mask to the mask interface. Turn on the standard switch; the device will automatically perform a self-test. Rescuers can adjust the knobs to set initial parameters such as respiratory rate, flow rate, and oxygen concentration.

[0029] 2. Respiratory support stage: The gas source enters the gas path control integrated module, is regulated by various gas path control components, is mixed in the gas mixing chamber, and is then delivered to the patient through the gas delivery pipeline.

[0030] 3. Real-time monitoring and adjustment phase: Rescuers observe the patient's breathing status and equipment operating parameters. If the respiratory support effect is not ideal or the parameters are abnormal, the parameters are adjusted by adjusting the knob, and the airway control integrated module is adjusted accordingly.

[0031] 4. End stage: When the patient's breathing is stable or the ventilator is no longer needed, first turn off the external air supply, then cut off the airway through the regular switch, remove the patient's mask, disconnect the ventilator from the air supply, and finally clean and store the equipment.

[0032] Compared to existing technologies, this design significantly improves the integration of airway control, effectively reduces the size and complexity of the device. The various functional components work together more efficiently, enabling precise airway control and providing stable, personalized respiratory support for patients. Simultaneously, it reduces the device's failure rate, improves reliability, and reduces maintenance costs and complexity, providing convenient and efficient equipment support for medical rescue.

[0033] This design offers a wide range of options for product optimization and upgrades, enhancing the product's flexibility and adaptability. Different solutions can meet the needs of different customer groups, allowing companies to flexibly adjust product design and production strategies based on various factors. This helps companies improve product competitiveness, meet the diverse needs of the market and users, and drive continuous technological progress in the industry.

Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
