Description
Technical Field
The invention belongs to the field of medical instruments, and particularly relates to a disinfection respirator.
Background
Respiratory infectious diseases (such as Severe Acute Respiratory Syndrome (SARS) and novel coronavirus pneumonia (COVID-19)) are a group of infectious diseases with relatively high transmission speed, and are mainly characterized in that pathogens are latent, live and propagate in the respiratory tract, then spread into the air through droplets formed by coughing and sneezing, and then inhaled into the respiratory tract by other people to realize the spread of the pathogens, namely, the main transmission path of the respiratory infectious diseases is the droplets. Of course, respiratory infections can also be transmitted by other means, such as contact transmission, fecal oral transmission, eyelid transmission, etc., but airborne transmission is the primary route of respiratory infections.
When a patient becomes infected with a pathogen of an upper respiratory infectious disease, the infection process usually has a latent phase and an attack phase. Generally, patients are not or less contagious in the latent phase, but are very contagious during and around the onset. For the novel coronavirus pneumonia, the virus has strong infectivity even in a latent period. Since respiratory infections are mainly carried out by droplet transmission, a large number of pathogens are present in the respiratory tract of patients, which if left uncontrolled, on the one hand are released in the outside air and make more healthy people become infected with pathogens, and on the other hand are extremely harmful to the patient himself, since pathogens in the respiratory tract can undoubtedly infect the patient himself and can be airborne to all organs in the respiratory tract.
In the traditional prevention and treatment of respiratory infectious diseases, the control of pathogen multiplication in patients is placed at the first place, and the killing of pathogens in the respiratory tract of patients is placed at the second place, because during the growth of many respiratory infectious pathogens, the release of pathogens is mainly carried out in patients. For example, influenza virus often attacks the respiratory tract, is released into the patient and propagates, and when it occurs, it releases a large amount of virus into saliva or the like in the respiratory tract of the patient, and then it spreads to the outside by sneezing or coughing, thereby showing infectivity. Although the pathogens of respiratory infectious diseases propagate in the body of a patient and release a large amount of pathogens only in the attack period, and the control of growth and propagation in the body is the key problem, timely killing of the pathogens in the respiratory air of the patient is very effective, because the concentration of the pathogens in the respiratory air is very high, and the self illness of the patient is aggravated if the pathogens are not killed in time.
Therefore, effective killing of pathogens in the respiratory tract of a patient is important for the control of infectious diseases, and there is a great need in the art to devise an effective disinfecting respirator to kill pathogens in the respiratory tract of a patient.

Preferably, the inhalation cover 124 is connected to a medicine tube so that medicine or the like can be squeezed into the case 119, and the medicine can be inhaled into the air upon inhalation and then delivered into the patient. An oxygen tube can also be inserted into the inspiration cover to provide oxygen for the patient.
To ensure synchronous movement of the intake piston 122 and the exhaust piston 112, the intake piston 122 and the exhaust piston 112 are connected to the same piston drive rod 120, and the particular intake piston 122 and the exhaust piston 112 may be connected to the same piston drive rod 120 by a piston rod 118. A support rod can be arranged between the two piston pull rods to keep the translation and the stability of the two piston pull rods. Specifically, the piston driving rod 120 is driven manually or electrically, for example, manually, i.e., manually pulling and pushing the piston driving rod to drive the piston to move, or a motor may be installed at the position, and the piston driving rod 120 is connected to an output shaft connector of the motor, so as to adjust the rotation speed of the motor, and the motor drives the piston to move.
In order to ensure airtightness and prevent gas leakage from the cylinder, piston seal rings 111 are provided on both the intake piston 122 and the exhaust piston 112.
As shown in fig. 1, the sterilizing compartment is connected to a first one-way exhaust port 108 for sterilizing gas discharged from a user, and is connected to the first one-way exhaust port 108 via an exhaust connection pipe 110.

The killing tube 116 has an inlet connected to the first one-way vent 108, and in particular, to the first one-way vent 108 via an exhaust connection tube 110, and an outlet located within the killing chamber 114. Preferably, kill tube 116 is serpentine or spiral shaped to increase gas sterilization time. The heating wire 115 is electrically connected to reach the required temperature, and the temperature can be adjusted by controlling the temperature control plate.
In order to improve the portability of the disinfection respirator, the killing box can also be designed as a solution killing box, is suitable for mild patients and is convenient for the patients to walk. The solution killing box comprises a killing box body 114 and a killing pipe 116 arranged in the killing box body 114, wherein the killing box body 114 is used for storing a killing solution, the killing solution is used for killing pathogens in gas, the inlet of the killing pipe 116 is connected with the first one-way exhaust port 108, particularly connected with the first one-way exhaust port 108 through an exhaust connecting pipe 110, and the outlet of the killing pipe 116 is immersed in the killing solution, so that the gas exhaled by a user is discharged into the killing solution, and the pathogens are effectively killed. When in use, the killing box is carried on the body of a patient, which is simple and convenient. The killing solution is a solution for killing pathogens, and can be medical alcohol, strong acid, etc.
In order to facilitate the gas after sterilization to be discharged out of the sterilization box and to prevent dust from entering the sterilization box, a sterilization box ventilation cover 113 is provided on the sterilization box body 114, and a dust screen is provided on the sterilization box ventilation cover 113 to prevent dust from entering the sterilization box body.
The working process of the disinfection respirator of the invention is as follows:
after the user wears the disinfection respirator, the breathing of the user follows the movement of the piston. When the exhaust piston 112 is pulled downward, the user exhales, the first one-way exhaust port 108 is closed, the second one-way intake port 107 is opened, and the exhaust gas in the body enters the exhaust piston 112 through the second one-way intake port 107 via the breathing connection pipe 105. Meanwhile, the air suction piston 122 synchronously moves downwards, the first one-way air inlet 123 is opened, the second one-way air outlet 125 is closed, the external air is filtered by the air suction cover 124 and is sucked into the air suction piston 122 through the first one-way air inlet 123, and the liquid medicine and the like in the liquid medicine pipe are adsorbed by the sucked air to form mixed gas; when the two pistons are pushed upwards at the same time, the first one-way air inlet 123 and the second one-way air inlet 107 are closed at the same time, the first one-way air outlet 108 and the second one-way air outlet 125 are opened at the same time, the waste gas passes through the first one-way air outlet 108 and is conveyed to the killing box through the exhaust connecting pipe 110 to be killed and discharged to the external space, and the mixed gas absorbed with the liquid medicine passes through the second one-way air outlet 125 and enters the body of the user through the breathing connecting pipe 105 and the mask. The above processes are repeated, so that the aims of killing and discharging pathogens in the waste gas can be fulfilled, the user is ensured to inhale air without pathogens, and the pathogens in the discharged gas are effectively killed.
The sterile respirator of the present invention is suitable for use with confirmed or suspected patients, particularly patients who have experienced dyspnea. In order to reduce the physical consumption, an electric driving mode can be adopted, namely, an electric motor is arranged to drive the piston to move. The larger the volume per breath, the more beneficial the elimination of pathogens, insofar as the patient can tolerate, but care must be taken in the case of the patient during the procedure. If an electric driving mode is used, the rotating speed of the motor and the stroke of the piston need to be adjusted, so that a patient has a better treatment effect when using the electric respirator, a certain comfort level is ensured, and possible harm caused by forced breathing is prevented. Whether manual or electric, the state of the patient must be closely followed and timely adjusted according to the situation. As the device is mainly used for patients, the position of the killing box can be fixed, so that a more effective and longer-lasting killing mode can be used, namely an electrothermal killing mode is used, namely the discharged waste gas passes through a high-heat electric heating wire to physically and directly kill pathogens. The killing solution can also be used, so that electric energy is not needed, and the application place is wider.
The disinfection respirator designed by the invention essentially helps patients to breathe deeply and eliminates pathogens in the air of the respiratory tract of the patients during the breathing process by using the disinfection respirator. The air-breathing-type sterilization device is characterized in that waste gas in a patient body is sucked out when the patient exhales, then the waste gas is sent to a sterilization box for pathogen sterilization, and finally the sterilized gas is discharged into an external space. When helping the patient to inhale, filter the inspiratory outside air through the filter screen to mix into mist with medicine liquid, oxygen etc. and press in the patient respiratory at last. In short, the respirator increases the respiratory capacity of a patient or helps the patient to breathe, and pathogen killing is carried out on the exhaust gas exhausted by the patient, so that the clean air exhausted to the outside is ensured.
The disinfection respirator of the invention can not only provide air filtered by pathogens for a patient, but also exhaust the exhaust gas exhaled by the patient to the outside air after being killed, thereby achieving the effects of preventing the patient from polluting the air in the external space and treating the patient, and the function of the disinfection respirator is different from that of the existing commonly used respirator.
The disinfection respirator has simple manufacturing structure, convenient operation and low price, can be applied to patients in large quantity, effectively blocks each patient, namely an infection source, from releasing pathogens to the outside, thereby keeping the outside air clean, and simultaneously reducing the concentration of the pathogens in the air in the patient body, thus being beneficial to the prevention and treatment of the whole epidemic situation and the individual patients.
The disinfection respirator mainly aims at patients with mild symptoms or less serious illness, and is mainly designed for killing pathogens in the bodies of the patients and reducing the pollution of air in the external space, so that the disinfection respirator has a protection effect and a treatment effect. For patients with mild symptoms or less serious illness, the protective effect of the disinfection respirator is to kill the toxic gas exhaled by the disinfection respirator and prevent the toxic gas from polluting the external air, so that the concentration of pathogens in the respiratory tract space of the patients is effectively reduced, and the infection of the pathogens to the uninfected organisms in the patients is avoided. Because the disinfection respirator can kill pathogens in the body of a patient, the air transmission path of the pathogens can be effectively blocked, the number of the pathogens which are transmitted from one part of the lung to another part which is not adjacent to the lung through air transmission is reduced, and thus large-area infection of the lung of the patient is effectively avoided.
The effect of the disinfection respirator depends on the air infection rate of infectious diseases, and if the proportion of pathogens which are propagated and released in the air is large, the treatment effect is very ideal. Even if the proportion of pathogens released in the air is not large, the ability to kill this portion of pathogens can serve as a very valuable adjunct therapy. Because the disinfection respirator also has the functions of adding liquid medicine, oxygen and the like, the disinfection respirator also has the atomization effect. In a word, the disinfection respirator has positive effects on prevention and treatment of respiratory infectious diseases, and is particularly suitable for prevention and treatment of infectious diseases such as novel coronavirus pneumonia.
