This patent serves asInnovative Medical Device Technology Integrating Emergency Respiratory Support and Suction Functions, which not only resolves the pain points of traditional manual resuscitators—namely, the need for additional suction equipment and low emergency response efficiency—but also promises to provide more efficient and convenient device support for emergency scenarios such as cardiopulmonary resuscitation (CPR).

Upper Airway Obstruction Caused by Sputum Impactionis a common precipitating factor for dyspnea and asphyxia in clinical emergency settings, such as during cardiopulmonary resuscitation (CPR).Maintain Airway PatencyIt is the primary prerequisite for assisted ventilation and saving patients' lives. When sputum accumulates in the patient's pharynx or oral cavity, it directly obstructs the gas exchange pathway. Failure to promptly clear secretions while simultaneously providing effective ventilation can rapidly lead to a decline in blood oxygen saturation, exacerbate respiratory failure, and even trigger severe complications such as cardiac arrest. This places higher demands on the functionality and coordination of emergency medical equipment.

In current clinical emergency care, there are significant practical challenges in managing patients with sputum obstruction complicated by respiratory failure. On one hand, emergency interventions demand high timeliness, requiring medical personnel to rapidly perform two core procedures: maintaining airway patency and providing assisted ventilation. On the other hand, in traditional emergency protocols, ventilation and sputum suction are separate procedural steps that require the use of different devices—namely, a bag-valve-mask resuscitator and a sputum suction apparatus. The frequent switching between tools and procedural workflows during emergencies consumes valuable time, delays treatment, and reduces the success rate of resuscitation. Meanwhile, in on-site emergency settings where manpower and equipment space are limited, carrying multiple types of devices also increases the complexity of emergency preparedness.

Furthermore, existing simple resuscitator products exhibit significant functional deficiencies and fail to meet the clinical demand for integrated emergency care. Currently, mainstream simple resuscitators on the market offer only a single auxiliary ventilation function. Although equipped with components such as a self-inflating bag, disposable sterile membrane, and one-way valve to enable basic manual assisted ventilation, they lack integrated suction capabilities. Consequently, in cases of respiratory distress caused by sputum obstruction, additional suction devices are required to complete the rescue. Traditional simple resuscitators rely entirely on manual compression of the bag for air delivery, with both the force and frequency controlled solely by the operator. This manual dependence often leads to inconsistent pressure and unstable airflow, which not only compromises the effectiveness of assisted ventilation but may also cause secondary injury to the patient’s airways and lungs due to improper operation, thereby failing to align with the requirements for standardized clinical emergency care.

The core innovation of this patented invention for an integrated manual resuscitator with suction capability lies inBreaks the traditional design paradigm of separating ventilation and sputum suction in medical devices, through“Negative Pressure Integrated Cap + Switching Mechanism”core structural design, achieving functional integration and rapid switching on a single device, while combiningBalloon Structure Optimization, Hygienic Protection Design, Automated Compression...and multiple other detailed innovations, balancing emergency response efficiency, usage safety, and operational convenience, thereby establishing multiple technical advantages over traditional manual resuscitators.

InCore Function Integration, patented designThe negative pressure integrated cover is equipped with an air inlet and a sputum suction port., combined withGourd-shaped sealing plate, pressure shaft, and leverThe integrated switching mechanism allows medical personnel to simply toggle the lever within the limit slot, thereby enabling the sealing plate to alternately block either the air inlet or the sputum suction port. This facilitates rapid switching between ventilation and sputum suction modes, significantly saving time otherwise spent on equipment changes during emergency care. Meanwhile, the differentiated design, featuring an air inlet larger than the sputum suction port, ensures adequate airflow during ventilation while maintaining stable and appropriate negative pressure during sputum suction. This prevents airway injury or pulmonary hypoxia caused by excessive negative pressure, thereby mitigating the risk of secondary harm through design optimization.

InStructure and Performance OptimizationAbove,The balloon features an integrated molding design in which the hardness of the upper and lower sections is greater than that of the middle section., allowing the balloon to rapidly rebound after compression, thereby ensuring the operational efficiency of negative-pressure inhalation and air supply; additionally, a disposable annular elastic membrane installed inside the balloon adheres tightly to the inner wall upon compression and can be directly removed and replaced after use. This design not only prevents contamination within the balloon but also avoids cross-infection among different patients, enabling device reusability and reducing medical consumable costs. Furthermore, the device is equipped withElectric Telescopic Rod and Arc-Shaped Squeeze Blockcombination structure, replacing traditional manual squeezing of the balloon, to achieve automatic and uniform compression of the balloon. It addresses the pain points of uncontrollable manual squeezing force and unstable air supply, ensuring standardization and effectiveness of assisted ventilation.

AtOperation and Adaptabilityabove,The patented mounting bracket provides an integrated fixation solution for the equipment.The bottom ring base securely snaps onto the negative pressure integrated cover. The suction canister employs a dual-fixation method combining snap-fit and threaded connections, enabling rapid assembly and disassembly for convenient emergency operations and subsequent cleaning. The fixed mounting bracket on the outer side of the installation frame allows for detachable snap-fit connection to medical stretchers, hospital beds, wheelchairs, and other equipment, securing the respirator beside the patient to free healthcare workers’ hands and adapting to various emergency scenarios in hospitals and public places. Detailed design features—such as the elastic clamping strips in the limit slide grooves, the sealing rings at the edges of the sealing plate, and the arc-shaped sealing gaskets inside the negative pressure integrated cover—further enhance the device’s sealing performance. This ensures a sealed negative pressure state of the balloon during sputum suction, while opening the limit slide grooves to form dual air intake channels during ventilation, allowing the device to maintain optimal performance in different operating modes.

The market for integrated emergency ventilation and suction devices currently exhibits a competitive landscape characterized by scenario-based segmentation. Different R&D entities have launched specialized products tailored to diverse clinical scenarios and patient populations, each featuring unique technological highlights and practical application value. Collectively, these innovations fill the market gap left by traditional single-function emergency devices, fostering a diversified competitive environment with distinct product differentiations.
