Description

Technical Field

[0001] This utility model relates to a lung-assisted treatment system, specifically a system for expectoration, expectoration clearing, sputum suction, and waste sputum treatment. Background Technology

[0002] Autopsy experts have discovered numerous sputum plugs in the lungs of patients who died from severe or critical lung infections. Clinicians treating severe or critical lung infections can only rely on medication for inflammation and detoxification, and mechanical ventilation to provide oxygen and sustain life. This is what is traditionally referred to as internal medicine focusing on medication, and surgery focusing on surgical techniques. Internal medicine clinicians determine the appropriate drug type and dosage based on the patient's specific condition. However, limitations in drug efficacy, drug resistance, and other side effects make it difficult to achieve a complete cure and achieve effective anti-inflammatory and detoxifying treatment. Currently, especially in the resuscitation of severe or critically ill patients with highly virulent viral lung infections, there are no specific, effective drugs for treatment.

[0003] Because critically ill patients often have extensive and severe lung infections, their lungs produce large amounts of secretions that are highly concentrated, viscous, and densely packed with viruses. Due to the inability to expel these secretions promptly, they accumulate in the lungs and bronchi, forming sputum plugs. This leads to decreased lung tissue compliance—a reduced ability to expand and contract, and decreased flexibility—creating a vicious cycle that exacerbates the condition and leads to death. This is a key reason why autopsy experts have found large amounts of sputum plugs in the lungs of patients with lung infections. Therefore, the principle of "sputum containing toxins, and toxins containing sputum; expelling sputum is detoxifying" has been proposed. How to continuously expel the virus-laden secretions accumulated in the lungs to achieve the therapeutic effects of expectoration, anti-inflammation, and detoxification is a crucial and critical challenge in saving the lives of severely and critically ill patients with respiratory infections. Currently, the purpose of sputum suction in clinical practice is to improve ventilation and oxygenation, not necessarily to achieve expectoration, anti-inflammation, and detoxification. Furthermore, it failed to consider that during the expectoration of sputum from a patient's lungs, the force of the patient's exhalation and the force of the pulmonary secretions flowing out are in the same direction. This means that the force of inhalation and the force of the pulmonary secretions flowing out counteract each other—a crucial issue.

[0004] Current clinical methods for sputum suction are quite simple: one end of a suction catheter is connected to a disposable plastic bottle with a negative pressure air source, and the other end is inserted into the trachea. The catheter has suction holes on its outer wall. During suctioning, medical staff repeatedly pull the catheter, relying on their sense of touch to suction out the sputum through the side holes. Because severely ill and critically ill patients produce large amounts of highly concentrated and viscous secretions, it is necessary to increase the negative pressure during suctioning, using the suction catheter to repeatedly pull and suction the airway. This method is not only inefficient intubation, but the repeated pulling and suctioning can easily cause airway abrasions and secondary infections, hindering recovery. Furthermore, it is limited by the length and diameter of the suction catheter, meaning it can only enter the trachea for suctioning, not the bronchi, and cannot remove sputum from the bronchial walls. Clinicians use bronchoscopy to assist in suctioning sputum for individual patients. However, bronchoscopy is primarily used for clinical diagnosis and is expensive, making it unsuitable for suctioning large numbers of patients. Therefore, medical staff often rely on repeatedly turning and patting the patient's back or using a suction machine to vibrate the patient's back to expel sputum, allowing secretions from the lungs and bronchi to flow into the trachea before suctioning. This not only increases the workload for medical staff but also risks worsening the patient's condition, and many severely or critically ill patients with lung infections cannot be turned or have their backs vibrated for this purpose. A more significant problem is that patients often have high body temperature, and the secretions are highly viscous, adhering to the inner walls of the trachea and bronchi. Not only does it affect ventilation and oxygen supply, but it also hinders the removal of pulmonary secretions, obstructing the patient's airway system, thereby reducing the efficiency of the ventilator, resulting in ineffective ventilation, and impeding oxygen delivery to the alveoli, leading to hypoxia and even death by suffocation. Currently, no written evidence has been found in relevant medical literature regarding "strong secretions adhering to the inner walls of the trachea and bronchi." Clinically, there are no solutions (other than medication) for treating secretions adhering to the inner walls of the trachea and bronchi. Therefore, how to continuously expel pulmonary secretions into the bronchi, clearing secretions adhering to the inner walls of the trachea and bronchi, and reducing resistance to pulmonary secretion overflow to improve ventilation and oxygen supply is another crucial challenge and issue for saving the precious lives of critically ill patients.

[0005] Currently, in clinical practice, the use of disposable plastic suction bottles to collect sputum not only requires frequent replacement, but also necessitates the disposal of used bottles according to regulations. The large-scale manufacture, use, and disposal of these bottles wastes significant resources, increases medical costs, and poses a risk of cross-infection to medical staff and those involved in disposing of the bottles. Furthermore, it is time-consuming, labor-intensive, and costly, hindering environmental protection and the scientific management of biosafety. Utility Model Content

[0006] The purpose of this invention is to provide a treatment plan that performs sputum expectoration, anti-inflammatory and detoxification according to respiratory rhythm; and to provide a plan for simultaneously clearing and suctioning secretions adhering to the inner wall of the trachea and bronchi and treating waste sputum; in order to solve the problems of difficulty in suctioning, ventilation and oxygen supply for severe and critically ill patients with lung infections, improve the life-saving rate, and solve the problem of centralized treatment of waste sputum.

[0007] The present invention provides a system for treating sputum, clearing sputum, suctioning sputum, and waste sputum. The system includes a sealed sputum container, a stirring shaft inside the container, stirring blades on the stirring shaft, and the stirring shaft being driven to rotate by a stirring motor. The sputum container is equipped with a suction tube, a drain tube, a negative pressure tube, and a positive pressure tube, all communicating with the inner cavity of the container. The drain tube is connected to a wastewater treatment device at its end, and is connected to a tap water pipe and a disinfectant supply pipe, which is connected to a disinfectant tank. The system also includes a liquid tank connected to a supply pipe. A foot switch and a vibration switch are connected in parallel on the suction tube and the supply pipe, respectively.

[0008] A dual-channel suction tube is connected to the end of the suction tube and the fluid supply tube. The dual-channel suction tube contains two channels that branch off at the tail to form two branches. The front end of one channel is the suction port, and the rear end is connected to the suction tube. The front end of the other channel has several micropores, and the rear end is connected to the fluid supply tube. Under positive pressure, liquid or special liquid passes through the micropores to produce a small amount of liquid in a nebulized state. This can prevent damage to the trachea and bronchi, and can also clear phlegm and remove secretions adhering to the inner walls of the trachea and bronchi.

[0009] The positive pressure pipe is connected to the positive pressure gas source, and the disinfection supply pipe and the supply pipe are driven by peristaltic pumps respectively.

[0010] The positive pressure pipe is connected to both the disinfectant tank and the liquid tank at its end. A positive pressure branch is provided on the positive pressure pipe, and the positive pressure branch is connected to a positive pressure gas source. A solenoid valve switch is provided on the positive pressure branch.

[0011] The sputum container is also equipped with a first electrode switch and a second electrode switch. The lower end of the first electrode is higher than the lower end of the second electrode, and the lower end of the first electrode is slightly lower than the lower ports of the positive pressure tube and the negative pressure tube. The lower end of the second electrode is slightly higher than the lower port of the suction tube.

[0012] A thermostat is installed on the liquid tank, a disinfection dosing pipe is connected to the disinfection tank, a third electrode switch is installed on the disinfection tank, and a fourth electrode switch is installed on the liquid tank.

[0013] A water supply pipe is connected to the tap water pipe. The water supply pipe is used to replenish water for the disinfection tank and / or liquid tank. A filter is installed on the water supply pipe connected to the liquid tank.

[0014] It also includes a controller motherboard, which is connected to an electromagnetic oscillator, specifically a mattress-type electromagnetic oscillator. For example... Figure 5 .

[0015] It also includes an endotracheal tube and a dual-channel suction catheter. Used to connect to an expiratory support device or ventilator, the endotracheal tube has a side tube and an insertion port at its front end. The dual-channel suction catheter enters through the side tube and exits through the insertion port. Two flexible metal wires are installed inside the wall of the dual-channel suction catheter, arranged along its axial direction, with the two wires located on opposite sides of the axis. A rotary positioner is installed on the outer wall of the dual-channel suction catheter. The front end of each flexible metal wire is fixedly connected to the front end of the dual-channel suction catheter, and the rear end of each flexible metal wire protrudes from the tube wall and is mounted on the corresponding rotary positioner. The rotary positioner controls the bending of the dual-channel suction catheter by releasing and retracting the flexible metal wire.

[0016] A sealing ring and a sealing cap are provided on the side passage pipe.

[0017] The dual-channel suction catheter is used in conjunction with the endotracheal tube. A side tube is designed on the outer wall of the endotracheal tube, with a sealing ring and cap installed on it. When the dual-channel suction catheter is inserted into the endotracheal tube, it fits tightly with the sealing ring. The dual-channel suction catheter can rotate 360 ​​degrees longitudinally within the endotracheal tube. The tip of the dual-channel suction catheter uses a design combining flexible metal wire and corrugated tubing. By adjusting the length of the flexible metal wire, the lengths of the two flexible wires on both sides of the corrugated tubing at the tip of the dual-channel suction catheter can be changed, thereby controlling the lateral swing of the tip of the dual-channel suction catheter to greater than 180 degrees.

[0018] When a patient urgently needs sputum clearance and suctioning, the sealing cap on the side tube can be opened at any time. Under visual guidance, the dual-channel suction catheter is inserted into the endotracheal tube in just over 10 seconds, reaching the trachea and bronchi for suctioning. This achieves precise and rapid sputum removal, clearance, and suctioning. It is convenient to use and easy to operate, eliminating the need for repeated pulling of the suction catheter, thus avoiding tracheal abrasions and the pain caused to patients by suctioning by touch. This not only saves valuable time for medical staff in rescuing critically ill patients with respiratory infections, but also significantly reduces their workload. Compared to the previous cumbersome method of turning and patting the back to remove sputum accumulated in the bronchi and then repeatedly pulling the suction catheter, this new method is time-saving and labor-saving.

[0019] In terms of manufacturing cost, endotracheal intubation tubes and dual-channel suction catheters are inexpensive, using sealing rings, flexible metal wires, and ordinary-hole cameras (since the cameras are not for diagnostic purposes, they only need to visualize secretions in the trachea and bronchi). This makes them suitable for clinical use as patient consumables. In terms of manufacturing process, the length and thickness of the tubes and corrugations can be modified. The two tubes can be used together or individually. In particular, the micro-pores designed at the front of the dual-channel suction catheter can produce a nebulized liquid for small amounts of specialized fluid, effectively clearing sputum. It is also suitable for diagnosis and treatment of patients in multiple disciplines, such as the gastrointestinal system. It can be used for interventional treatments such as drug nebulization, laser therapy, and radiofrequency ablation.

[0020] This invention, based on the autopsy report of a patient who died from a lung infection, which stated "a large number of sputum plugs in the patient's lungs," explicitly proposes for the first time the important theoretical viewpoint that: "In patients with severe or critical lung infections, the force of inhalation and the force of pulmonary secretion overflow are mutually antagonistic, while the force of exhalation and the force of pulmonary secretion overflow are in the same direction. The patient's exhalation period is the optimal time for pulmonary secretion overflow (i.e., the optimal time for expectoration). The vibration of the gas during exhalation, combined with the vibration of the back outside the body, creates resonance during the lung exhalation period, which is an important technical method for pulmonary expectoration. Sputum contains toxins, and toxins contain sputum; expectoration is detoxification, and expectoration is an important technical treatment plan for anti-inflammatory and detoxification." Therefore, avoiding the inhalation period... The interaction between air pressure and the force exerted on secretions during exhalation is controlled by a timer controller. This controller regulates the frequency of the solenoid valve and the vibration of the electromagnetic vibrator during the patient's exhalation, causing resonance in the lungs during this period. This achieves a combined treatment approach of anti-inflammatory and detoxifying medication with expectoration. In practical application, especially for severe and critically ill patients with lung infections, the vibration is used to expel sputum with each exhalation. Medical staff adjust the intensity, frequency, and duration of the vibration based on the patient's condition, continuing until the highly viscous, virus-laden secretions accumulated in the lungs are expelled. Bedside X-rays of the lungs can then be taken to observe the differences before and after expectoration, highlighting its significant therapeutic effect. This method also prevents sputum plug formation and can appropriately reduce the dosage of some antibiotics, thereby minimizing the side effects of these drugs. This is the core technical element of this invention for expectoration.

[0021] Based on the autopsy report of a patient who died from a lung infection, which stated "a large number of sputum plugs in the patient's lungs," this invention is the first to clearly propose that "severe and critically ill patients with lung infections have a wide range of infections, deep-seated symptoms, abundant secretions, high body temperature, and high viscosity, which adhere to the inner walls of the trachea and bronchi, posing a major problem and issue that urgently needs to be solved." The large amount of secretions adhering to the inner walls of the trachea and bronchi and accumulating within the bronchi obstructs the overflow of lung secretions, causing sputum plug formation, severely affecting the patient's ventilation and oxygen supply, and endangering the patient's life. Therefore, a dual-channel suction catheter is provided at the end of the suction catheter and the liquid catheter. The purpose is to use a small amount of liquid (preferably a dedicated liquid) to dissolve and clear the sputum adhering to the inner walls of the trachea and bronchi and accumulating within the bronchi, while simultaneously suctioning the sputum. This reduces the resistance to the overflow of sputum from the lungs, facilitates sputum overflow, prevents sputum plug formation, reduces the heavy workload of medical staff in turning and patting the patient's back to expel sputum, and improves ventilation and oxygen supply. This provides the objective conditions for developing a solution to cleanse the secretions inside the trachea and bronchi. It is another core technical element of this utility model for expectoration, sputum removal, and simultaneous sputum suction.

[0022] This utility model provides a comprehensive treatment plan for patients with severe and critical lung infections, combining anti-inflammatory and detoxifying drug treatments with expectoration, anti-inflammatory, and detoxification treatments, as well as expectoration, sputum removal, simultaneous suctioning, ventilation, and oxygen supply. This plan plays a crucial role in saving the precious lives of patients with severe and critical lung infections, and its effectiveness and significance are profound.

[0023] This invention utilizes the existing wastewater treatment plant in the hospital to collect sputum, which is normally non-flowing, into a sealed sputum container. After initial disinfection with a disinfectant solution, water is added for dilution and mixing, transforming it into a flowable liquid that can then be discharged into the hospital's wastewater treatment plant for centralized processing. While this method appears extremely simple, it is precisely this often overlooked approach that is a key technology for reducing the mass production, use, and disposal of disposable suction bottles; preventing cross-infection among medical staff and those involved in the disposal of these bottles; saving time, effort, and money; and promoting environmental protection and scientific biosafety management. Its significance is profound.

[0024] Currently, hospitals have sewage treatment plants, but lack a pipeline system for the flow of waste sputum and waste fluid to these plants. This invention provides the objective conditions for designing a pipeline system for the flow of waste sputum and waste fluid into the sewage treatment plant. (For example, by adding a drainage pipe to the sewage treatment plant next to the existing negative pressure air source and oxygen source at each patient bed. Even in the absence of a pipeline system for the flow of waste sputum and waste fluid to the sewage treatment plant, this does not affect the independent or combined use of the solenoid valve-operated sputum suction vibrator, mattress-type vibrating sputum suction device, expiratory vibrating sputum suction device, endotracheal tube, and dual-channel suction tube. Waste sputum can also be discharged into the existing disposable suction tube.) This invention helps to supplement and improve hospital building design specifications, especially for infectious disease hospitals. This invention is also applicable to other organs, such as the gastrointestinal tract, digestive system, and the treatment of waste fluid generated during surgery, and has far-reaching significance for improving the level of hospital development and construction.

Detailed Implementation

[0032] like Figure 1 , Figure 2 As shown, this utility model includes a sealed sputum container 1. A stirring shaft 2 is installed inside the sputum container 1, and stirring blades 3 are installed on the stirring shaft 2. The stirring blades 3 are located at the bottom of the sputum container 1. The stirring shaft 2 is driven to rotate by a stirring motor 4. A sealing ring is provided between the stirring shaft 2 and the wall of the sputum container 1 to ensure that the stirring shaft 2 can rotate and to ensure sealing. A suction tube 5, a drain tube 6, a negative pressure tube 7, and a positive pressure tube 8 are provided on the sputum container 1 and communicate with the inner cavity of the sputum container 1. The ends of the negative pressure tube 7 and the positive pressure tube 8 extend into the sputum container 1 and are located at the top of the sputum container 1. The end of the suction tube 5 extends into the sputum container 1 and is located in the middle of the sputum container 1. The end of the drain tube 6 extends into the sputum container 1 and is located at the bottom of the sputum container 1.

[0033] The drain pipe 6 is connected to a sewage treatment device at its end. A water supply pipe 9 and a disinfectant supply pipe 10 are connected to the drain pipe 6, and the disinfectant supply pipe 10 is connected to a disinfectant tank 11. The water supply pipe 9 is connected to the disinfectant tank via a water replenishment pipe 33. The liquid collected in the sputum container 1 is discharged to the sewage treatment device through the drain pipe 6 for centralized treatment, preventing leakage of waste liquid. A one-way valve 19 is installed between the water supply pipe 9 and the drain pipe 6 to prevent sewage from the drain pipe 6 from entering the water supply pipe 9.

[0034] This utility model also includes a liquid tank 12, which is equipped with a heater. The liquid tank 12 is connected to a liquid supply pipe 13, which is connected to a dual-channel suction tube. The liquid supply pipe 13 provides a small amount of liquid to the patient's trachea and bronchi to clear and remove phlegm from the inner walls of the trachea and bronchi, while suctioning is performed simultaneously to clean the secretions from the inner walls of the trachea and bronchi or to treat phlegm.

[0035] Parallel foot switches B14 / C14 and vibration switches B15 / C15 are installed on the suction tube 5 and the infusion tube 13, respectively. Both foot switches B14 / C14 and vibration switches B15 / C15 can control the connection or disconnection of the tubing. When medical personnel are performing sputum drainage or treatment on patients, they can control the foot switches B14 / C14 with their feet, eliminating the need for them to use their hands. Medical personnel can operate devices such as endotracheal intubation while simultaneously controlling the foot switches B14 / C14, working in conjunction with the dual-channel endotracheal suction tube for sputum drainage and medication administration. This allows one medical person to complete the entire operation, alleviating the shortage of medical personnel in emergency situations.

[0036] On the other hand, this invention achieves suction and flushing functions through a vibration switch. A rapid, intermittent negative pressure is transmitted to the patient's lungs via the foot switch B14 or vibration switch B15 on the suction tube 5, thereby performing vibration suction. This is suitable for cases where the patient's sputum is highly viscous and difficult to suction. A small amount of liquid is rapidly and intermittently injected into the patient's lungs and trachea via the foot switch C14 or vibration switch C15 on the supply tube 13, thereby clearing and removing secretions from the inner walls of the trachea and bronchi, as well as secretions accumulated within the trachea and bronchi, to resolve blockages in the trachea or bronchi.

[0037] There are multiple ways to drive the drain pipe 6 and the supply pipe 13, such as positive pressure drive or pump drive.

[0038] like Figure 1 As shown, a positive pressure drive is adopted. One end of the positive pressure pipe 8 extends into the sputum container 1, and the other end is connected to the medicine disinfection container 11 and the liquid container 12. A positive pressure branch 18 is provided on the positive pressure pipe 8. The positive pressure branch 18 is connected to the positive pressure air source, and the positive pressure pipe 8 is connected to the liquid supply pipe 13.

[0039] A solenoid valve switch and a positive pressure regulator 20 are installed on the positive pressure branch 18 to provide a constant positive pressure airflow to the positive pressure pipe 8.

[0040] Since positive pressure gas is used as the driving force, both the disinfectant tank 11 and the liquid tank 12 need to be sealed containers. After the positive pressure gas is injected into the disinfectant tank 11 or the liquid tank 12, the disinfectant or medicine is forced to flow out and into the disinfection supply pipe 10 or the supply pipe 13 by pressure.

[0041] like Figure 2 As shown, a pump-driven system is used, with the positive pressure pipe 8 connected to air pressure. The drain pipe 6 and the supply pipe 13 are driven by peristaltic pumps. A first peristaltic pump 16 is installed on the drain pipe 6, located on the drain line between the water supply pipe 9 and the disinfection supply pipe 10. Switches are installed on the drain pipe 6 between the water supply pipe 9 and the sputum container 1, and on the drain pipe 6 between the disinfection supply pipe 10 and the sewage treatment device. The first peristaltic pump 16 powers the extraction of liquid from the sputum container 1 and discharges it into the sewage treatment device. A solenoid valve A17 is installed on the positive pressure pipe 8 to control the connection or disconnection between the sputum container 1 and the positive pressure air source. When the first peristaltic pump 16 extracts liquid, the switch on the negative pressure pipe 7 is closed and the switch on the positive pressure pipe 8 is opened, allowing air pressure gas to enter the sputum container 1 to facilitate the extraction of liquid. A second peristaltic pump 17 is installed on the liquid supply pipe 13. The second peristaltic pump 17 is used to draw a small amount of liquid from the liquid tank to the patient's trachea and bronchi to clear sputum. The liquid tank 12 is a non-sealed container.

[0042] Water pipe 9 is connected to medicine disinfection tank 11 and liquid tank 12 via water replenishment pipe 30, replenishing liquid water to medicine disinfection tank 11 and liquid tank 12. Since the liquid in liquid tank 12 is used to clear phlegm for patients, a filter 31 is installed on the pipe leading to liquid tank 12 to purify the tap water into pure water.

[0043] A thermostat 21 is installed on the liquid tank 12 to maintain the temperature of the liquid tank, ensuring that the small amount of liquid injected into the patient's trachea and bronchi will not irritate the patient's lungs. A disinfection and drug addition tube 32 is connected to the disinfection tank 11, and a drug addition tube is connected to the liquid tank 12. A third electrode switch 28 is installed on the disinfection tank 11, and a fourth electrode switch 29 is installed on the liquid tank 12. Drug is added to the disinfection tank via the disinfection and drug addition tube 32, and to the liquid tank via the drug addition tube. After a certain proportion of water is introduced, the mixture forms a disinfectant solution or a drug solution. The addition of drug or water is controlled by the third electrode switch 28 or the fourth electrode switch 29.

[0044] The sputum container 1 is also equipped with a first electrode switch 22, a second electrode switch 27, a pressure sensor, and a display indicator 23. The lower end of the first electrode 22 is higher than the lower end of the second electrode 27, and the lower end of the first electrode 22 is slightly lower than the lower ports of the positive pressure tube 8 and the negative pressure tube 7. The lower end of the second electrode 27 is slightly higher than the lower port of the suction tube 5. When the liquid level in the sputum container 1 exceeds the first electrode switch 22, the two electrodes of the first electrode switch 22 connect, triggering a signal that stops the suction tube 5 and starts the drainage tube 6 to drain the liquid from the sputum container 1. When the liquid level exceeds the second electrode 27, the two electrodes of the second electrode 27 connect, triggering a signal that closes the negative pressure tube 7, opens the drainage tube 6, and opens the positive pressure tube 8, allowing the first peristaltic pump 16 to drain the liquid from the sputum container 1. The pressure sensor and display device 23 is used to monitor the pressure inside the sputum container 1 and control the negative pressure regulator 34 on the negative pressure pipe 7 and the negative pressure regulator 35 on the parallel pipe through feedback.

[0045] This utility model also includes a controller motherboard 24, a power supply 25, and a display 26. The controller motherboard 24 is connected to various switches, foot switches B14 / C14, vibration switches B15 / C15, electrode switches, positive pressure regulator 20, negative pressure regulator, and thermostat 21 for signal control of the on / off of various pipelines.

[0046] like Figure 3 As shown, an endotracheal tube 38 is provided at the end of the fluid supply tube or the end of the suction tube. A side passage tube 39 is provided on the endotracheal tube 38. A sealing ring 42 and a cap 52 are provided at the end of the side passage tube 39. An intubation port 45 is provided at the front end of the endotracheal tube 38.

[0047] The dual-channel suction catheter 46 is inserted into the side tube 39 of the endotracheal tube 38 and exits through the insertion port 45 of the endotracheal tube 38. A sealing ring 42 is provided at the port of the side tube 39, and the sealing ring 42, the inner wall of the side tube 39, and the outer wall of the dual-channel suction catheter 46 are tightly fitted together. The dual-channel suction catheter contains two channels, which are separated from each other by a partition wall. The two channels fork at their tails to form two branches. The front end of one channel is the suction port, and the rear end is connected to the suction catheter. The front end of the other channel has several micro-holes 48, and the rear end is connected to the fluid supply tube. Two flexible metal wires 40 are installed inside the wall of the dual-channel suction tube 46. The flexible metal wires 40 are arranged along the axial direction of the dual-channel suction tube 46, and the two flexible metal wires 40 are located on both sides of the axial direction. A rotary positioner 41 is installed on the outer wall of the dual-channel suction tube 46. The front end of the flexible metal wire 40 is fixedly connected to the front end of the dual-channel suction tube 46, and the rear end of the flexible metal wire 40 passes through the tube wall and is installed on the corresponding rotary positioner 41. The bending of the dual-channel suction tube 46 is controlled by the rotary positioner 41 to raise and lower the flexible metal wire 40.

[0048] An air hole 44 is provided on the side wall of the endotracheal tube 38, and an air bag 43 is provided on the outer wall of the endotracheal tube 38. A light source, a camera, and micro-holes are provided at the front end of the dual-channel suction tube 46.

[0049] The part near the front end of the dual-channel suction tube 46 is a corrugated tube 49.

[0050] At the end of the liquid tube or suction catheter, the endotracheal tube is connected to the patient's lungs. The dual-channel suction catheter 46 has two branch tubes 50 at the end (e.g., Figure 4 (As shown). The fluid supply tube is connected to one branch 50 of the dual-channel suction catheter 46, and the suction catheter is connected to the other branch 50 of the dual-channel suction catheter 46. The patient's lungs are ventilated and oxygenated via the endotracheal tube 38. When suctioning is required, the dual-channel suction catheter 46 is inserted, and its tip is adjusted to the predetermined position, connecting the end of the dual-channel suction catheter 46 to the suction catheter. Negative pressure is used to suction out sputum from the patient's trachea and into a sputum container. When expectoration or cleaning of the patient's trachea and bronchi with a small amount of fluid is required, one branch 50 of the dual-channel suction catheter 46 is connected to the medication tube, and the other branch 50 is connected to the suction catheter. By controlling the inflow of fluid into the medication tube and the outflow of fluid into the suction catheter, simultaneous expectoration and suctioning of sputum from the inner walls of the patient's trachea and bronchi are achieved.

[0051] This utility model and such Figure 6The expiratory assist device (application number 2021231375216) is used in conjunction with an expiratory assist device and an endotracheal tube. A solenoid valve switch 36 is installed between the expiratory assist device and the endotracheal tube. A mattress-type electromagnetic vibrator 37 is installed on the hospital bed (e.g., Figure 5 (As shown). Considering the counteracting effects of the negative force during inhalation and the overflow force from pulmonary secretions, the force exerted on the trachea during exhalation is in the same direction as the overflow force from pulmonary secretions. Through the controller's mainboard 24, the frequency of the solenoid valve switch 36 and the intensity of the electromagnetic vibrator 37 are controlled periodically during the patient's exhalation period to achieve resonance in the patient's lungs during exhalation, resulting in therapeutic effects of vibration-induced sputum expectoration, anti-inflammation, and detoxification.

[0052] like Figure 6 As shown, the solenoid valve switch is installed at the end of the expiratory valve of the expiratory assist device or ventilator. During the patient's expiratory period, the controller controls the switching frequency of the solenoid valve to generate an expiratory gas cough vibration effect, which helps to expel sputum.

[0053] The key characteristic of expiratory assist devices is that while normal individuals expiratory pressure is equal to air pressure, critically ill patients with lung infections exhibit significant differences due to variations in the extent and severity of infection, overall health status, lung tissue flexibility and expansion / contraction, and respiratory muscle resistance. Therefore, it is crucial to tailor the expiratory pressure, flow rate, and duration to each individual patient's specific situation. When the patient is receiving oxygen, appropriately reducing the expiratory time and extending the inspiratory time improves the ventilator's efficiency. Conversely, when the patient is expectorating sputum, appropriately extending the expiratory time and reducing the inspiratory time enhances expectoration efficiency and improves overall ventilation and oxygenation support.

[0054] The respiratory assist device utilizes existing positive and negative pressure air supply pipelines in the hospital. It cleverly uses a gas pressure-volume-flow-rate converter (i.e., a gas flow meter) connected to the positive and negative pressure air supply to precisely meet the diverse and complex physiological needs of patients with respiratory diseases, including expiratory pressure, flow rate, time, resistance-to-breath ratio, compliance, expiratory volume, positive expiratory pressure, and tidal volume. This allows for personalized treatment plans. Doctors adjust the air pressure and respiratory time ratio to be higher, equal to, or lower than the patient's needs based on their condition, expectoration, ventilation, and oxygen supply. This better addresses the patient's expectoration and ventilation / oxygen supply issues, significantly improving the efficiency and treatment level of the ventilator. It also provides favorable conditions for clinical medical workers to conduct treatment, rehabilitation, and research on cardiopulmonary and respiratory diseases.

[0055] This invention relates to a sputum container 1. A suction tube 5 draws sputum from the patient's trachea and bronchi. The drawn sputum is temporarily stored in the sealed sputum container 1. A disinfectant supply tube 11 injects disinfectant into the sputum container 1 through a disinfectant supply tube 10 to disinfect the liquid inside. A small amount of liquid is then injected into the patient's trachea and bronchi through a liquid supply tube 13 to clear sputum. Simultaneously, this small amount of liquid is drawn out by the suction tube 5, and the waste liquid is collected in the sputum container 1. Once the collected liquid in the sputum container 1 reaches a certain volume, it is discharged through a drain tube 6 to a wastewater treatment device for centralized processing to prevent leakage of virus-laden liquid and avoid infection of medical personnel. Since the sputum container 1 mainly collects sputum, which has a high viscosity and is difficult to expel, liquid needs to be injected into the sputum container 1 for dilution, and the mixture is stirred by a stirring blade 3. When the drain pipe 6 becomes blocked, the pipe is cleared by tap water pipe 9, and the pipe and sputum container 1 are cleaned.

[0056] Specific operating methods: as follows Figure 1 As shown, during sputum expectoration, the expiratory valve on the expiratory assist device or the ventilator opens. The controller controls the frequency of the solenoid valve switch 36 and the mattress-type electromagnetic vibrator 37 in the patient's expiratory pathway. The controller also synchronously controls the frequency of the vibration switch B15, causing lung resonance during the patient's exhalation. When the patient inhales, the electromagnetic vibration stops, and the vibration switch B15, solenoid valve switch 36, and electromagnetic vibrator 37 close. They reopen at the next breath. Medical personnel, based on the patient's condition, continuously expel secretions from the lungs when the patient needs to exhale, achieving continuous sputum expectoration, anti-inflammatory, and detoxification effects. The tip of the suction catheter connected to the dual-channel system does not extend beyond the endotracheal tube to prevent damage to the lungs, trachea, and bronchi from pressures lower than air pressure. The suction canister contains two pressures: suction pressure and a slightly lower air pressure for expectoration. The electromagnetic vibrator (mattress-type electromagnetic vibrator 37), the electromagnetic switch of the expiratory assist device, and the vibration switch B15 on the sputum expectoration device can be used together or individually, facilitating flexible operation by doctors for emergency patient care. The vibration process during sputum expectoration also serves as a rehabilitative exercise for the lungs. When patients require lung rehabilitation training, the vibration pattern during inhalation and exhalation can be controlled according to the patient's needs.

[0057] When suctioning, close solenoid valves A1 and A3, open solenoid valves A2 and A5, and perform suctioning via foot switch B14. Connect the dual-channel suction catheter to the suction inlet and insert it into the tracheobronchus for suctioning.

[0058] When expectoration is required, solenoid valves A4 and A14 open, connecting the inlet to the supply tube of the dual-channel suction catheter. The controller can then control the vibration switch C15. Under positive pressure, a small amount of liquid is injected into the trachea and bronchi through 48 micro-holes to clear secretions accumulated in and on the inner walls of the trachea and bronchi, while simultaneously suctioning sputum. The injection of the small amount of liquid into the trachea and bronchi can be controlled via foot switch C14 or by controlling the vibration switch C15 to administer a quantitative and timed dose. Medical personnel can flexibly operate according to the actual needs of the situation.

[0059] When waste sputum needs to be discharged into the sewage treatment plant, when the liquid level in the sealed suction can reaches the second electrode switch 27, the switch 27 signals the controller, which then opens solenoid valves A4, A6, A7, A11, and A12. Under positive pressure, disinfectant solution is added until the liquid level reaches the first electrode switch 22, which then closes solenoid valves A4 and A12. After the stirring motor 4 thoroughly stirs the sputum, the controller opens solenoid valves A3, A4, A6, A7, and A8, and the positive pressure forces the waste sputum into the sewage treatment pipeline for further treatment at the sewage treatment plant.

[0060] When the solution needs replenishment of medicine and water, solenoid valves A9, A10, and 32 open. When the liquid level reaches the third electrode switch 28, solenoid valves A9, A10, and 32 close. The medicine can be added separately via the disinfection dosing tube 32 controlled by the controller.

[0061] When the liquid tank needs to be filled, solenoid valves A9, A13, and A15 open, and the liquid enters the tank after being filtered through filter 31. When the liquid level reaches the fourth electrode switch 29, solenoid valves A9, A13, and A15 close. Special liquids or medicines can be added by controlling solenoid valve A15.

[0062] This utility model has three methods for expectoration:

[0063] 1. A timer, an exhalation valve, and a controller control the solenoid valve 36 switch installed on the exhalation end of the expiratory assist device or ventilator to control the switching frequency during the patient's exhalation period, so as to generate gas vibration when the patient exhales, which can be used as an expiratory vibration expectorant.

[0064] II. The electromagnetic vibrator is controlled by a timer, an exhalation valve, and a controller. The electromagnetic vibrator 37 is mattress-shaped. When the patient is in the exhalation phase, the electromagnetic vibrator starts to vibrate, which plays a role in patting the patient's back to expel sputum. It can be used as a mattress-type vibrating sputum expectorant.

[0065] III. It consists of a timer, an exhalation valve, a controller, a sputum container, solenoid valves A1, A3, A4, and A5, a vibration switch B15, an endotracheal tube, and a dual-channel suction catheter. When the patient expectorates sputum, solenoid valves A1, A3, A4, and A5 open, and A2 closes to adjust the expectoration pressure in the sputum container. During the patient's exhalation period, the timer and controller control the switching frequency of the vibration switch B15, which generates expiratory gas vibration through the gas in the dual-channel suction catheter. It can be used as a solenoid valve-operated vibrating expectorant.

[0066] The three types of sputum-clearing vibrations can be used in combination or individually, and doctors can flexibly apply them according to the patient's needs.

[0067] Note: The electromagnetic vibrator 37 consists of a magnet and a coil. When the coil is given voltages of different frequencies, the magnet will produce vibrations of different strengths. This is the working principle of the electromagnetic vibrator. The electromagnetic vibrator can be designed as a mattress, so that the patient can lie on the bed in a natural state. When expectorating phlegm, the switching frequency of the electromagnetic vibrator coil is controlled to produce vibrations of different strengths on the patient's back. There is no need to turn over or pat the back to achieve the effect of expectoration.
