[0002] Sudden bronchospasm during general anesthesia surgery is one of the clinical emergencies, with an incidence of approximately 0.2%-4%. The patient's risk of acute asphyxiation increases dramatically due to strong contraction of airway smooth muscle, and blood oxygen saturation can drop sharply to below 60% within minutes.

[0034] It should be noted that sudden bronchospasm during general anesthesia surgery is an extremely critical condition. The patient's airway will be severely suffocated due to strong contraction, and effective intervention must be carried out every second. This integrated emergency device is designed to deal with such high-risk scenarios. It integrates key oxygen supply, positive pressure ventilation and emergency drug atomization systems into one, and is equipped with ergonomic fixation, quick connection interface and multiple safety designs, striving to achieve seamless connection from equipment activation to effective airway management in the shortest time. When the anesthesiologist is sensitive to the patient's typical signs of bronchospasm such as respiratory distress, prolonged exhalation, wheezing or a sudden drop in blood oxygen saturation, the routine anesthesia operation must be interrupted immediately and the emergency device must be activated instantly. First, the doctor needs to quickly lift the Open or rotate the second installation box 2 (the fixing plate 3 and its groove design inside it are designed to fit tightly against the edge of the operating room equipment table or a specific bracket when the box is unfolded or placed, providing initial limit and anti-shift stability). At this moment, the properly stored ventilator 4 (located in the core area inside the first installation box 1), the oxygen cylinder 5 (stably placed on the special placement seat 51 at the bottom of the first installation box 1, and firmly fixed by the lock buckle 151, the connecting belt 153 and the lock 152 of the clamping assembly 15 to prevent it from tipping over during transportation or operation), the air supply pipe 102 and the nebulizer 12 and other key components are clearly exposed to the field of vision, and then the air supply assembly 10 - the air pipe 102 (installed on the right opening of the three-way valve 91 through the standard connection port 101) is removed. The anti-injury ring 103 (smooth and rounded edge design) at the end ensures that the risk of soft tissue injury is reduced when the mask or intubation interface contacts the patient's face or oropharynx. The blocking piece 104 and the built-in limit ring 105 in the middle of the trachea 102 restrain the tube body to prevent excessive bending and folding, ensuring smooth airflow. The anti-injury ring 103 at the right end of the trachea 102 is quickly and tightly connected to the patient's mask (covering the mouth and nose or connecting the intubation laryngeal mask) or artificial airway (such as the trachea 102 catheter interface). This is the lifeline for building an emergency artificial airway. The high-pressure oxygen from the oxygen cylinder 5 is received and converted by the ventilator 4. As the central gas processing hub, the core function of the ventilator 4 is to intelligently control the input oxygen and generate it on demand and in quantity according to the preset safety parameters, and then send the precisely controlled therapeutic level The airflow is pressure-sent to the inlet of the three-way valve 91 through the second delivery pipe 8. The airflow flows through the opened valve channel without any obstruction into the trachea 102 connected to the patient, instantly filling the patient's alveoli on the verge of collapse with up to 100% pure oxygen concentration and a preset positive pressure level, strongly resisting airway closure, increasing intra-alveolar pressure, forcibly opening the spasmodic and contracted bronchial tree 102, and rapidly increasing the patient's arterial oxygen partial pressure and saturation, preliminarily reversing the fatal hypoxic state during the golden rescue window. Removing physical obstruction is only the first step. The severe spasm of the smooth muscle of the bronchus 102 due to etiology urgently requires fast-acting drug intervention. At this time, the nebulizer 12 located at the right rear end of the first installation box 1 and firmly supported by the support assembly 11 (the support base 111 is firmly installed on the inner wall of the box)The convex plate 112 provides lateral support to prevent the equipment from shaking, and the inlet and outlet 113 opened are convenient for pipe connection and placement) and work synchronously. The first aid liquid is quickly injected into the nebulizer 12 storage cup, and the nebulizer 12 drive unit is immediately started, and the high-frequency vibration or high-speed airflow is instantly cut into the drug aerosol ultrafine particles. At this time, the high-speed constant flow gas generated by the ventilator 4 is immediately introduced into the bottom of the nebulizer 12 medicine cup or the core excitation area through the third delivery pipe 121 (connected to the air inlet port of the nebulizer 12). This continuous and sufficiently strong power airflow, on the one hand, acts as a carrier gas to suck up the dispersed drug particles in the cup to form a drug-containing aerosol. On the other hand, its kinetic energy is also directly involved in breaking up the drug liquid and maintaining the stable delivery of the aerosol. These life-saving The ultrafine particles of the drug are quickly discharged from the air outlet of the nebulizer 12 along with the air flow, and are pressed into the three-way valve 91 through the fourth delivery pipe 13 (at this time, the fourth delivery pipe 13 is connected to the left opening of the three-way valve 91), and quickly merge with the uninterrupted pure oxygen flow from the passage 1 in the valve. After the two gases are efficiently and evenly mixed in the mixing chamber, they become an integrated therapeutic airflow of high-concentration oxygen and high-density drugs, which continuously flushes the patient's blocked airway through the trachea 102. The atomized drug particles are directly impacted and attached to the spasmodic airway mucosal surface under the influence of the high-speed airflow. β2 receptor agonists such as salbutamol can take effect within a few seconds to one minute, strongly relax the smooth muscle cells of the bronchus 102, significantly expand the narrowed airways at all levels, reduce airflow resistance, and promote The ciliary clearance function fundamentally resolves the crisis of airway spasm. During the entire tense and time-sensitive emergency ventilation process, in order to maximize the sealing fit between the pipeline system (especially the mask area) and the patient's face and prevent gas leakage caused by pipeline traction or instrument displacement, the doctor or assistant needs to quickly peel off the first Velcro 147 on the back side of the mounting seat 141 and the second Velcro 148 on the front side, and place the bottom of the mounting seat 141 covered with soft medical cotton close to the side of the patient's cheek, and then apply moderate pressure to the adjusting member 143 to make it overcome the tension of the spring 145 (under the precise limit of the guide member 146) and slide axially, pushing the contact block 144 firmly against the pipeline, and then reducing the hand pressure to make the adjusting member 143 move against the spring. Under the action of 145, it rebounds slightly but still maintains contact pressure, completing the fine-tuning of the adaptive limit fixation, and finally the second Velcro 148 with strong adhesion is turned over and firmly attached to the first Velcro 147, thereby stably anchoring the airway 102 and the mask in the optimal working position. This design effectively solves the risk of loosening of the pipeline caused by unconscious activities or bumps in transportation of the patient. When severe airway spasm is initially relieved and the patient's vital signs tend to be stable, continuous physiological monitoring and precise adjustment of ventilation parameters are crucial. At this time, the ease of operation of the device design is also maintained. The oxygen cylinder 5 can be easily replaced or refilled with capacity through the convenient clamping component 15, and the atomized liquid can be replenished or replaced in real time without affecting the main oxygen flow.The power supply interface required for the operation of the ventilator 4 is always placed under the all-weather protection of the protective frame 16 on the rear side of the first installation box. The protective frame 16 provides reset damping through the torque of the torsion spring 17 mechanism. When the power is required, it can be easily opened and kept open. When the power is unplugged, it will automatically rebound to cover the interface immediately, eliminating the risk of liquid splashing or foreign objects touching and shorting out.
