Phlegm removal, phlegm clearing, phlegm suction and waste sputum treatment system

technical field

The invention relates to a pulmonary auxiliary treatment system, in particular to a system for eliminating phlegm, reducing phlegm, clearing phlegm, sucking phlegm and treating waste phlegm.

Background technique

An autopsy expert found a large number of phlegm plugs in the lungs of patients who died of new coronary pneumonia. At present, when clinicians treat severe and critically ill patients with lung infection, they can only rely on medication to reduce inflammation and detoxify, and use ventilators to provide ventilation and oxygen supply to save patients' lives. This is what people often say in the traditional sense, internal medicine Technology focuses on medication, and surgical technology focuses on using knives. The medication described by internal medicine clinicians refers to the determination of the appropriate drug species and dosage according to the different conditions of the patient's condition. However, limited by side effects such as drug efficacy, drug resistance, and drug resistance, it is difficult to achieve the therapeutic effect of anti-inflammatory and detoxification. At present, when rescuing severe and critically ill patients with lung infection and inflammation, there is no targeted specific drug treatment.

Critically ill patients with pulmonary infection and inflammation have a wide range of infection and deep infection, and the secretions produced in the lungs are large, dense, viscous, and virus-containing. Because it cannot be discharged in time, secretions containing a large amount of virus are deposited in the lungs and bronchi, thereby forming phlegm plugs. It causes the compliance of the lung tissue to decrease, that is, the expansion and contraction ability and softness of the lung tissue decrease, forming a vicious circle, exacerbating the deterioration of the disease and leading to death. This is exactly why autopsy experts found in the autopsy of patients with lung infection and inflammation that there are a large number of phlegm plugs in the lungs. Therefore, they proposed that "phlegm contains poison, and poison contains phlegm. Expelling phlegm is detoxification." How to continuously excrete the secretions containing a large amount of virus accumulated in the lungs, so as to achieve the effects of expectoration, anti-inflammation, and detoxification, is the precious life and vital to the treatment of severe and critically ill patients with pulmonary respiratory system infection. A big problem and subject. At present, the purpose of expectoration and suction in clinic is ventilation and oxygen supply, not a treatment plan for expectoration, anti-inflammation, and detoxification. Furthermore, it is not taken into account that when the patient's lungs are expelled, the force of the patient's exhalation is in the same direction as the force of the overflow of the lung secretions. It is a very important issue that the force of inhalation and the force of overflow of lung secretions counteract each other.

The current clinical sputum suction method is very simple. One end of the suction tube is connected to a disposable plastic bottle with a negative pressure air source, and the other end is inserted into the trachea. There is a suction side hole on the outer wall of the suction tube. , When sucking sputum, the medical staff repeatedly pulls the sputum suction tube, and sucks the sputum from the side hole of the sputum suction tube by feeling. Since severe and critically ill patients produce a lot of secretions, high concentration, and strong viscosity, it is necessary to increase the negative pressure when suctioning sputum, and use a sputum suction tube to repeatedly pull and suck sputum between the airways. This method of sputum suction not only has low intubation efficiency, but repeated pulling of the sputum suction tube may easily cause airway scratches and secondary infection, which is not conducive to recovery, and is limited by the length and thickness of the sputum suction tube. Enter the trachea for suction, but cannot enter the bronchi for suction. Clinicians use bronchoscopes to assist sputum suction for individual patients, but bronchoscopes are mostly used for clinical diagnosis of diseases, and the cost is high, so they are not suitable for a large number of patients. Press and vibrate the back of the patient with the expectorant machine to expel the sputum, so that the secretions below the lungs and bronchi flow into the trachea and then use the sputum suction tube to suck the sputum. This not only increases the work intensity of the medical staff, but also The operation may cause the condition to worsen, and many severe and critically ill patients with lung infections cannot turn over and vibrate their back for expectoration and suction. The more important problem is: the patient's body temperature is high, and the secretion has a strong viscosity, which adheres to the inner wall of the trachea and bronchi. It not only affects the effect of ventilation and oxygen supply, but also hinders the elimination of lung secretions and blocks the patient's respiratory system, thereby reducing the working efficiency of the ventilator, resulting in ineffective ventilation, which is not conducive to the effective arrival of oxygen to the alveoli, resulting in hypoxia of the patient, resulting in asphyxiation death At present, in the relevant medical literature, there is no textual basis for "strong secretions adhere to the inner wall of the trachea and bronchi"; Treatment solution for secretions on the inner wall. So, how to remove the secretions that stick to the inner wall of the trachea and bronchus and accumulate in the bronchi. Reducing the overflow resistance of lung secretions and improving the effect of ventilation and oxygen supply is another difficult problem and topic that is crucial to saving the precious lives of severe and critically ill patients.

At present, clinically, the use of disposable sputum suction plastic bottles to recover sputum not only needs to be replaced frequently, but also the replaced disposable plastic bottles must be destroyed in accordance with the relevant national regulations. A large number of disposable sputum suction plastic bottles are manufactured, used, and destroyed. Bottles, not only waste a lot of resources but also increase medical costs, but also easily cause cross-infection to medical staff and staff who participate in the destruction of disposable plastic suction bottles. And it is time-consuming, laborious, and expensive, which is not conducive to environmental protection and scientific management of biological safety.

Under positive pressure, liquid or special liquid passes through Microporous, which produces a small amount of liquid in an atomized state, which can not only prevent damage to the trachea and bronchus, but also reduce phlegm and clear phlegm, and remove secretions adhered to the inner walls of the trachea and bronchi.

The positive pressure tube is connected to a positive pressure air source, and the disinfection liquid supply tube and the liquid supply tube are respectively driven by a peristaltic pump.

The end of the positive pressure tube communicates with the liquid medicine disinfection tank and the liquid tank at the same time, and a positive pressure branch is arranged on the positive pressure tube, and the positive pressure branch communicates with a positive pressure gas source. An electromagnetic valve switch is arranged on the positive pressure branch.

It also includes a controller mainboard, the controller mainboard is connected with an electromagnetic oscillator, and the oscillator is a mattress type electromagnetic oscillator. Figure 5.

Also includes tracheal intubation, dual-channel suction tube. It is used to communicate with an exhalation assistance device or a ventilator. A side tube is opened on the endotracheal tube, and an intubation port is opened at the front end of the endotracheal tube. The through tube penetrates into and passes out from the intubation port; two flexible metal wires are arranged inside the tube wall of the dual-channel sputum suction tube, and the flexible metal wires are along the axis of the dual-channel sputum suction tube direction, and two flexible metal wires are located on both sides of the axis respectively, a rotary positioner is provided on the outer wall of the dual-channel sputum suction tube, and the front end of the flexible metal wire is fixedly connected to the dual-channel sputum suction tube The front end of the flexible metal wire passes through the tube wall and is installed on the corresponding rotary positioner, and the flexible metal wire rope is retracted by the rotary positioner to control the bending of the dual-channel sputum suction tube.

A sealing ring and a sealing cover are arranged on the side channel.

The dual-channel suction tube is used in conjunction with the tracheal intubation. A side tube is designed on the outer wall of the endotracheal tube. A sealing ring and a sealing cover are installed on the side tube. Anastomotic, double-channel suction tube can be rotated 360 degrees longitudinally and tightly within the endotracheal tube. The front end of the dual-channel sputum suction tube is combined with a flexible metal wire and a bellows design method.

Accurate and rapid expectoration, phlegm clearing, and phlegm suction. It is easy to use, flexible and simple to operate, and does not need to repeatedly pull the suction tube, thereby avoiding scratches on the trachea and pain to the patient caused by suctioning by feeling. This not only wins precious time for medical workers in rescuing the lives of severe and critically ill patients with pulmonary respiratory disease infection, but also greatly reduces the work intensity of medical staff. The clumsy method of slapping the back brings the sputum accumulated in the bronchi into the trachea, and then repeatedly pulls the heavy labor caused by the sputum suction tube to suck the sputum. The method of the present invention saves time and effort.

In terms of manufacturing costs of endotracheal intubation and dual-channel suction tubes, sealing rings, flexible wires, and ordinary hole-type cameras are used (because the cameras are not used for diagnosis, it is enough to see the secretions in the trachea and bronchi). The cost is low, and as a consumable for patients, it is convenient for clinical promotion and use. In terms of manufacturing process, the length and thickness of the cannula and the corrugation can be changed. The two cannula can be used together or alone, especially the micropores designed in the front part of the dual-channel suction tube can produce a small amount of liquid (special liquid). Like atomized liquid, it plays the role of reducing phlegm and clearing phlegm. At the same time, it is suitable for the diagnosis and treatment of patient parts in multidisciplinary fields, such as for the gastrointestinal system. It can be used for interventional treatments such as drug liquid atomization, laser, and radio frequency.

Based on the report of a large number of phlegm plugs in the lungs of patients found in the autopsy of patients with new crowns, the present invention clearly states for the first time: "For patients with severe and critical lung infections, the force of inhalation and the force of the overflow of lung secretions are produced. An important point of view is that the force of exhalation and the overflow of lung secretions are in the same direction. The patient's exhalation period is the best time for lung secretions to overflow (that is, the best time for expectoration) , the gas generated during exhalation vibrates and the back vibrates outside the body to form the resonance of the lungs during exhalation, which is an important technical method for lung phlegm discharge. Phlegm contains poison, and poison contains phlegm. Expelling phlegm means detoxification, and phlegm discharge It is an important technical treatment plan for anti-inflammation and detoxification." Therefore, in order to avoid the mutual antagonism of the air pressure during the inhalation period and the secretion overflow force, the timer controller is used to control the switching frequency of the solenoid valve during the patient's exhalation period, The vibration of the electromagnetic vibrator makes the patient's lungs resonate during the exhalation time period, and realizes the treatment plan combining anti-inflammatory, detoxification and expectoration, anti-inflammatory and detoxification. Severely ill and critically ill patients vibrate and excrete sputum every time they exhale. According to the patient's condition, the medical staff masters the intensity, frequency or time of continuous sputum excretion vibration, and removes the secretions that accumulate in the lungs with strong viscosity and high virus content. Until the lungs are discharged, the X-ray machine next to the bed can be used to take lung slices, and the difference between before and after sputum discharge can be observed, and the treatment effect is particularly important. Prevent the formation of phlegm plugs, and at the same time reduce the dosage of some antibacterial drugs appropriately, thereby reducing the harm caused by the side effects of drugs to the human body. It is the core technical requirement of expectoration of the present invention.

Based on the report of a large number of phlegm plugs in the lungs of patients found in the autopsy of patients with new crowns, the present invention clearly proposes for the first time that patients with severe and critical lung infections have a wide range of infection, deep degree, large secretions, high body temperature, and strong viscosity , being adhered to the inner wall of the trachea and bronchi, which is a major problem and subject that needs to be solved urgently. A large amount of secretions adhere to the inner wall of the trachea and bronchus of the lungs and accumulate in the bronchi, hindering the overflow of pulmonary secretions and causing the formation of phlegm plugs, seriously affecting the ventilation and oxygen supply of patients, and endangering the lives of patients. Therefore, a dual-channel sputum suction tube is installed at the end of the sputum suction tube and the liquid tube. Eliminates phlegm, clears phlegm, and simultaneously sucks phlegm. Thereby reducing the resistance of the overflow of sticky phlegm in the lungs, helping the overflow of sticky phlegm, preventing the formation of sputum plugs, reducing the heavy labor of medical staff to turn over and pat the back of the patient to expel sputum, and improve the effect of ventilation and oxygen supply. It also provides objective conditions for the development of medicinal solutions for cleaning the secretions on the inner wall of the trachea and bronchi. It is another core technical requirement of reducing phlegm, clearing phlegm and synchronous suctioning of phlegm in the present invention.

For patients with severe and critical pulmonary infection, the present invention provides a complete set of treatment closely combined with drug anti-inflammation, detoxification, treatment plan and expectorant, anti-inflammatory, detoxification treatment plan, as well as phlegm clearing, synchronous phlegm suction, ventilation and oxygen supply. The plan, for clinical medical workers, plays a vital role in rescuing the precious lives of patients with severe and critical lung infections, and its effect and significance are great.

The invention utilizes the favorable resources of the existing sewage treatment station in the hospital to recycle the non-flowing sputum into the sealed sputum tank, add the liquid for preliminary disinfection, add water to dilute and stir evenly, and turn it into a flowable liquid. It flows into the sewage treatment station in the hospital, which is convenient for centralized treatment. This method seems extremely simple, it is this method that is not noticed by ordinary people, it is to realize the mass production, use and destruction of disposable sputum suction plastic bottles, prevent medical staff and participate in the destruction of disposable sputum suction plastic bottles It is of great significance to deal with the staff, produce cross-infection, save time, effort and money, and is conducive to the improvement of environmental protection and scientific management of biosafety.

At present, the hospital has a sewage treatment station, but lacks a pipeline system for waste phlegm and waste liquid to flow to the sewage treatment station. The present invention provides objective conditions for the design of the pipeline for waste phlegm and waste liquid to flow into the sewage treatment station. (For example, beside the existing negative pressure air source and oxygen source of each patient bed, add a pipeline from the water to the sewage treatment station. In the absence of a pipeline system for waste sputum and waste liquid to flow to the sewage treatment station, it does not affect the electromagnetic Manufacture of valve switch type expectorant vibrator, mattress type vibrating expectorator, expiratory vibrating expectorator and endotracheal intubation, double channel suction tube for independent use and combined use, waste sputum can also be discharged into the current Disposable sputum suction tube) helps to supplement and improve the hospital building design code. Especially for hospitals specializing in infectious diseases. The present invention is also applicable to other organs, such as gastrointestinal tract, digestive system, and the treatment of waste liquid produced in the operation process, and has long-term significance for improving the development and construction level of hospitals.
