Description

Technical Field

[0001] The present invention relates to the field of medical disinfection devices, and particularly to a sealing device and working method for disinfecting the internal pipeline of a ventilator. Background Art

[0002] Ventilator treatment is an important means for rescuing critically ill patients. However, the pollution of the ventilator is a risk factor leading to nosocomial pulmonary infection in patients, increasing the mortality rate of patients. Therefore, it is necessary to disinfect the internal pipeline of the ventilator. At present, the disinfection methods for the outer shell, external airway and accessories of the ventilator are relatively mature in clinical practice. However, since the internal pipelines of most ventilators cannot be disassembled, it is inconvenient to carry out corresponding disinfection operations. However, the internal pipeline is connected to the external pipeline, and the exhaled gas of the patient contains bacteria or viruses, which may contaminate the internal exhalation path of the ventilator and cause infection risks.

[0003] Chinese Patent (Publication No. CN 111921049 A, Publication Date: November 13, 2020) discloses an epidemic prevention ventilator with a sterilization function. The sterilization module selects ethylene oxide gas as the sterilization gas, which can quickly and efficiently sterilize and disinfect the respiratory mask and the inside of each ventilation pipeline, and ethylene oxide will not cause damage to the equipment itself. The sterilization module is provided with a water-suction type vacuum pump and a reaction tank, and water can be injected into the reaction tank. The ethylene oxide gas in the partition chamber is pumped out by the water-suction type vacuum pump and transported to the reaction tank, and the discharge treatment of waste is completed by using the characteristic that ethylene oxide is easily soluble in water. A dedicated sterilization module is configured for the ventilator. However, for existing ventilators, it is inconvenient to additionally install a sterilization module and cooperate with the main body part of the ventilator, resulting in that the internal pipelines of current ventilators are still difficult to be effectively and reasonably disinfected. By means of an external ethylene oxide supply source, after ethylene oxide disinfection, the ports of the ventilator are still in an exposed state, and there is a risk of contamination caused by unclean external air carrying germs entering the internal pipelines of the ventilator. Summary of the Invention

[0004] The object of the present invention is to address the defects existing in the prior art and provide a sealing device and working method for disinfecting the internal pipeline of a ventilator. By adopting the method of storing disinfectant in a sealed container internally, and a connector is arranged on the container to be fitted and installed with the ventilator port. After the container is installed on the ventilator port, on the one hand, it can protect the ventilator port and avoid pollution caused by the outside to the position of the ventilator port and entering the internal pipeline through the ventilator port. On the other hand, the disinfectant inside the container can diffuse into the internal pipeline of the ventilator to achieve disinfection, avoiding the method of supplying ethylene oxide by large equipment, so that the internal pipelines of existing ventilators can be effectively and reasonably disinfected, improving flexibility and safety.

[0006] It includes a container, a cavity with one end open is formed inside the container, a connector adapted to the ventilator port is formed at the opening of the cavity, and a plugging member is cooperated at the opening to seal the cavity. A disinfectant is filled in the cavity. The plugging member removes the seal of the cavity opening under an external action, so that the cavity communicates with the internal pipeline of the ventilator.

[0007] Further, a positive pressure is formed in the cavity sealed by the plugging member to drive the disinfectant into the internal pipeline of the ventilator after the seal is removed.

[0008] Further, the disinfectant is ethylene oxide.

[0009] Further, a one-way area is provided on the container, a one-way flow member is provided in the one-way area, the one-way flow member controls the one-way flow of gas from inside the cavity to outside the cavity, and the one-way flow member is detachably cooperated with a sealing member to plug the one-way flow member.

[0010] The second object of the present invention is to provide a plugging device for disinfecting the internal pipeline of a ventilator, adopting the following scheme:

[0011] It includes a container and an adsorber. A cavity with one end open is formed inside the container, a connector adapted to the ventilator port is formed at the opening of the cavity, and a plugging member is cooperated at the opening to seal the cavity. A disinfectant is filled in the cavity. The plugging member removes the seal of the opening under an external action, so that the cavity communicates with the internal pipeline of the ventilator; a cavity with one end open is formed inside the adsorber, a connector adapted to the ventilator port is formed at the opening of the cavity, and an adsorption element is provided in the cavity to absorb the disinfectant discharged after flowing through the internal pipeline of the ventilator.

[0012] Further, a plugging member is cooperated at the opening of the cavity. The plugging member removes the plug of the cavity opening under an external action, so that the cavity communicates with the internal pipeline of the ventilator.

[0013] Further, the adsorption element is fixed inside the adsorber.

[0014] Further, when the container and the adsorber are cooperated with the ventilator port, the exposed part of the ventilator port is blocked and covered.

[0015] The third object of the present invention is to provide a working method of the plugging device for disinfecting the internal pipeline of a ventilator as described in the first object, including:

[0016] Place the ventilator to be disinfected in a safe environment, install the container on the inhalation port and / or the output port of the ventilator. Before or when installing the container, change the state of the plugging member so that the plugging member removes the seal of the cavity opening, and make the cavity communicate with the internal pipeline of the ventilator;

[0017] Let the ventilator stand still so that the disinfectant in the container enters the internal pipeline of the ventilator for disinfection and sterilization;

[0018] After the disinfection and sterilization are completed, clean the residual disinfectant in the internal pipeline of the ventilator and maintain the protection of the container for the port.

[0019] Furthermore, after the disinfection and sterilization are completed, adsorb the residual disinfectant in the internal pipeline of the ventilator to reduce the leakage of the disinfectant.

[0020] Compared with the prior art, the advantages and positive effects of the present invention are:

[0021] Aiming at the problem that it is difficult to conveniently disinfect the internal pipeline of the ventilator at present, a method of storing the disinfectant in a sealed manner inside the container is adopted. A connector is provided on the container to be fitted and installed with the ventilator port. After the container is installed on the ventilator port, on the one hand, it can protect the ventilator port, avoiding pollution caused by the outside to the position of the ventilator port and entering the internal pipeline through the ventilator port. On the other hand, the disinfectant inside the container can diffuse into the internal pipeline of the ventilator to achieve disinfection and sterilization, avoiding the method of supplying ethylene oxide by large equipment, so that the existing internal pipeline of the ventilator can be effectively and reasonably disinfected and sterilized, improving flexibility and safety.

[0022] A positive pressure is formed in the cavity sealed by the plugging member. The existence of the positive pressure can provide a driving force for the disinfectant to enter the internal pipeline of the ventilator after removing the seal of the plugging member, so that the disinfectant can diffuse more smoothly and efficiently to all parts of the internal pipeline. Compared with the situation without positive pressure, the speed and coverage range of the disinfectant entering the internal pipeline of the ventilator are improved, the disinfection and sterilization effect is enhanced, and the comprehensiveness and effectiveness of the disinfection are ensured.

[0023] The one-way area on the container is provided with a one-way flow component to control the one-way flow of gas from the cavity to the outside of the cavity. During the disinfection process, the one-way flow component cooperates with the sealing member to prevent the outside air from flowing back into the cavity, avoiding the pollution of the disinfectant by external pollutants, and at the same time maintaining the positive pressure environment in the cavity to a certain extent. The sealing member is detachably fitted on the one-way flow component and is used to plug the one-way flow component when the one-way flow function is not required, ensuring the sealing performance of the container during storage and transportation. After the disinfection and sterilization are completed, the residual disinfectant in the pipeline can be discharged from the inside to the outside, reducing the adverse impact of the residual disinfectant during use, preventing the outside air from entering the internal pipeline through the container and causing pollution, improving the storage stability and use safety of the disinfectant, and enhancing the controllability and reliability of the entire disinfection process.

[0024] The connector is arranged at the opening of the cavity and is adapted to the ventilator port, realizing the tight fit and installation between the container and the ventilator port, ensuring that an effective communication path can be established between the cavity and the internal pipeline of the ventilator after installation, and playing a sealing role at the same time to prevent the leakage of disinfectant and the entry of external pollutants. At the same time, the plugging device can be accurately and conveniently installed on the ventilator port, protecting the ventilator port and blocking the contact contamination of the ventilator port by external pollutants.

[0030] Embodiment 1

[0031] In a typical embodiment of the present invention, as Figures 1 - 2 shown, a plugging device for disinfecting the internal pipeline of a ventilator is given.

[0032] In the prior art, there are many problems in the disinfection of the internal pipeline of a ventilator. On the one hand, the method of using large equipment to supply ethylene oxide for disinfection not only has high costs, complex operations, but also poor flexibility, making it difficult to carry out timely and effective disinfection and killing treatment on the internal pipeline of the ventilator in various scenarios. On the other hand, the ventilator port lacks effective protection measures and is easily contaminated by the outside world. External pollutants may enter the internal pipeline through the port, affecting the normal use of the ventilator and even threatening the health of patients. Based on this, this embodiment provides a plugging device for disinfecting the internal pipeline of a ventilator. By setting a connector 6 on the container 1 that is adapted to the ventilator port, after the container 1 is installed on the ventilator port, the ventilator port can be protected. In addition, the container 1 is filled with a disinfectant. When the plugging member 4 removes the seal of the opening 3 of the cavity 2, the cavity 2 is connected to the internal pipeline of the ventilator, and the disinfectant can diffuse into the internal pipeline of the ventilator to achieve disinfection and killing.

[0033] By matching the container 1 with the ventilator port, it effectively avoids the pollution of the ventilator port position by the outside world and the entry of external pollutants into the internal pipeline through the ventilator port, ensures the clean environment of the internal pipeline of the ventilator, reduces the infection risk caused by external pollution, enables the existing internal pipeline of the ventilator to be effectively and reasonably disinfected, solves the limitation problem of supplying ethylene oxide for disinfection of large equipment, and improves the flexibility and safety of disinfection.

[0034] As Figure 1 shown, the main body of the plugging device for disinfecting the internal pipeline of the ventilator is the container 1. A cavity 2 with an opening 3 at one end is formed inside the container 1 for storing the disinfectant. The cavity 2 serves as a space for accommodating the disinfectant, enabling the disinfectant to be relatively isolated from the external environment. And it is installed in cooperation with the ventilator port through a connector 6 formed at the opening 3 of the cavity 2, playing a role of connection and positioning.

[0035] The connector 6 is arranged at the opening 3 of the cavity 2 and is adapted to the ventilator port to achieve a tight fit between the container 1 and the ventilator port, ensuring that an effective communication path can be established between the cavity 2 and the internal pipeline of the ventilator after installation, and at the same time playing a sealing role to prevent the leakage of the disinfectant and the entry of external pollutants.

[0036] Among them, the container 1 adopts a cup-shaped structure with an opening 3 at one end, and an anti-corrosion structure is arranged on the inner wall, such as a tin foil layer, an aluminum foil layer, etc.

[0037] In this embodiment, the connector 6 adopts the YY / T1040.1-2015 conical connector 6, which is the international general connector 6 for current ventilators. Using the standard connector 6 enables the plugging device to be accurately and conveniently installed on the ventilator port, facilitating the subsequent entry of the disinfectant into the internal pipeline of the ventilator, preventing the leakage problem caused by poor matching between the connector 6 and the ventilator port, and ensuring the tightness and safety of the entire disinfection process.

[0038] As Figure 1 shown, the plugging member 4 is fitted at the opening 3 of the cavity 2 for sealing the cavity 2 to prevent the leakage of the disinfectant before use. When subjected to external forces, it can remove the seal of the opening 3 of the cavity 2, connect the cavity 2 with the internal pipeline of the ventilator, and control the release timing of the disinfectant.

[0039] Specifically, the plugging member 4 can be made of tin foil, aluminum foil, a polymer material sealing layer, etc., and is cooperated with the opening 3 of the cavity 2 in a pasting manner. When no disinfection operation is carried out, the opening 3 of the cavity 2 is plugged to keep the disinfectant stably stored in the cavity 2; when disinfection is required, the plugging member 4 is removed by an external action, such as tearing off the plugging member 4, to remove the sealing effect of the plugging member 4 on the opening 3; or the plugging member 4 is directly directed towards the ventilator port so that the ventilator port pierces the plugging member 4, which can also achieve the purpose of removing the sealing of the plugging member 4 on the opening 3. After the ventilator port pierces the plugging member 4, the container 1 is installed on the ventilator port, and the disinfectant is conveyed into the internal pipeline of the ventilator. At this time, the debris of the plugging member 4 can be cleaned to prevent the adverse effect of the debris of the plugging member 4 on the plugging effect, thus completing the disinfection process and effectively controlling the disinfection process.

[0040] It should be noted that a positive pressure is formed in the cavity 2 sealed by the plugging member 4. The existence of the positive pressure can provide a driving force for the disinfectant to enter the internal pipeline of the ventilator after removing the seal of the plugging member 4, so that the disinfectant can spread more smoothly and efficiently to all parts of the internal pipeline. Compared with the situation without positive pressure, the speed and coverage of the disinfectant entering the internal pipeline of the ventilator are improved, the disinfection effect is enhanced, and the comprehensiveness and effectiveness of disinfection are ensured.

[0041] It can be understood that the internal positive pressure arrangement of the cavity 2 is adapted to the situation where the container 1 is installed on the ventilator port after the ventilator port pierces the plugging member 4. The positive pressure in the cavity 2 is realized by pre-filling clean compressed air. After the plugging member 4 is removed from the sealed state, the compressed air drives the disinfectant to discharge out of the cavity 2 and then enter the internal pipeline of the ventilator. It should be noted that in order to prevent the adverse impact of disinfectant leakage on the human body, it can also be used in a positive pressure disinfection environment. At the same time, if the container 1 is installed at the inhalation port of the ventilator, the disinfectant is guided by a pipeline or other means at the exhalation port of the ventilator, so that the excess disinfectant flowing out of the internal pipeline of the ventilator can be harmlessly treated.

[0042] Ethylene oxide has strong bactericidal ability and is filled in the cavity 2 as a disinfectant. Its function is to disinfect bacteria, viruses and other microorganisms in the internal pipeline of the ventilator, and destroy the protein and nucleic acid structures of the microorganisms, so as to achieve the disinfection purpose. In this embodiment, 2-5 ml of ethylene oxide is contained in the cavity 2. Ethylene oxide is a colorless transparent liquid at low temperature and a colorless gas with an ether pungent smell at normal temperature. Before use, the container 1 and the internal ethylene oxide are stored in a low-temperature environment. During use, ethylene oxide gradually evaporates in the external environment and then enters the internal pipeline of the ventilator. Ethylene oxide undergoes a specific alkylation reaction with microbial protein DNA, thereby hindering protein metabolism and inhibiting its normal biochemical reaction, so as to kill pathogenic microorganisms such as fungi, bacterial propagules and viruses, and achieve the sterilization purpose.

[0043] When ethylene oxide is used, corresponding adsorbents, water, etc. can be arranged at the open end of the ventilator to adsorb or dissolve ethylene oxide, achieving harmless treatment.

[0044] After disinfection, in order to volatilize the residual disinfectant in the ventilator, a channel for disinfectant volatilization is provided on container 1. Specifically, as Figure 1 shown, a one-way area is provided on container 1, and a one-way flow component 5 is arranged in the one-way area to control the one-way flow of gas from the inner cavity 2 to the outside of the inner cavity 2.

[0045] The seal is detachably fitted on the one-way flow component 5 and is used to block the one-way flow component 5 when the one-way flow function is not required, ensuring the sealing performance of container 1 during storage and transportation. During the disinfection process, the seal seals the one-way flow component 5 to prevent outside air from flowing back into the inner cavity 2, avoiding the contamination of the disinfectant by external pollutants, and at the same time maintaining a positive pressure environment in the inner cavity 2 to a certain extent. After disinfection, the residual disinfectant inside the pipeline can be discharged from the inside to the outside, reducing the adverse effects of the residual disinfectant during use, preventing external air from entering the internal pipeline through container 1 and causing pollution, improving the storage stability and use safety of the disinfectant, and enhancing the controllability and reliability of the entire disinfection process.

[0046] In this embodiment, the one-way flow component 5 can adopt a micro one-way valve structure. When the pressure in the inner cavity 2 is greater than the outside, the valve plate of the micro one-way valve opens, and the air entraining the disinfectant can be discharged from the inner cavity 2; when the outside pressure is greater than the inner cavity 2, the valve plate of the micro one-way valve closes tightly to prevent outside air from flowing back. The one-way flow component 5 can also adopt a thin film one-way sheet structure, and a thin film material with one-way air or liquid permeability characteristics, such as some special polymer films, is selected and installed at the opening 3 of the one-way area. The thin film is specially treated to only allow the disinfectant in the inner cavity 2 to pass through in a specific direction, while preventing external substances from entering in the reverse direction.

[0047] The seal can be selected from metal sealing paper, polymer sealing layer, etc., and is used to block the one-way flow component 5 when the one-way flow function is not required, ensuring the sealing performance of container 1 during storage and transportation.

[0048] Embodiment 2

[0049] In another typical implementation manner of the present invention, as Figures 1 - 3 shown, a blocking device for disinfecting the internal pipeline of a ventilator is given.

[0050] In this embodiment, in addition to including the container 1 in Embodiment 1, it also includes an adsorber 9. By combining the container 1 with the adsorber 9, the disinfection process of the internal pipeline of the ventilator is optimized from two key aspects of disinfectant supply and recovery, aiming to ensure the efficiency and safety of the disinfection process, effectively control the use range of the disinfectant, and reduce the potential harm to the environment and human body.

[0051] Similar to the first objective, a cavity 2 with an opening 3 at one end is formed in the container 1. The connector 6 at the opening 3 of the cavity 2 is used to adapt to the ventilator port. The cavity 2 is sealed by a plugging member 4 and stores the disinfectant. After the plugging member 4 is removed under an external action, the cavity 2 communicates with the internal pipeline of the ventilator, and the disinfectant is released to disinfect the pipeline. The disinfectant stored in the cavity 2 serves as the supply source of the disinfectant during the disinfection process, which is the starting link of the entire disinfection process and provides the necessary chemical substances for subsequent disinfection operations.

[0052] As Figure 2 shown, the cavity 7 in the adsorber 9 also has an opening 3 at one end, and the connector 6 at the opening 3 is adapted to the ventilator port. The adsorption element 8 provided in the cavity 7 can absorb the disinfectant discharged after flowing through the internal pipeline of the ventilator. When the plugging member 4 removes the plugging of the opening 3 of the cavity 7 under an external action, the cavity 7 communicates with the internal pipeline of the ventilator, realizing the recovery of the discharged disinfectant.

[0053] The adsorber 9 can cooperate with the container 1. After the container 1 completes the release of the disinfectant for disinfection, the adsorber 9 is responsible for recovering the used disinfectant to prevent it from escaping into the environment, forming a complete disinfectant recycling and control system.

[0054] The adsorption element 8 is fixed in the adsorber 9 and uses its own adsorption characteristics to capture and retain the disinfectant molecules discharged from the internal pipeline of the ventilator, thereby realizing the recovery of the disinfectant.

[0055] When the plugging member 4 that cooperates with the adsorber 9 is not undergoing the disinfection and recovery operation, it seals the opening 3 of the cavity 7 of the adsorber 9 to prevent external impurities from entering. When subjected to external forces, the plugging of the opening 3 of the cavity 7 is removed, enabling the cavity 7 to communicate with the internal pipeline of the ventilator, and starting the disinfectant recovery process. Similarly, the plugging member 4 of the adsorber 9 can be made of tin foil, aluminum foil, a polymer material sealing layer, etc., and is cooperated with the opening 3 of the cavity 7 in a pasting manner. When the disinfection operation is not carried out, it plugs the opening 3 of the cavity 7 to keep the adsorption element 8 stored stably in the cavity 7; when disinfection is required, the plugging member 4 is removed through external actions, such as tearing off the plugging member 4, to achieve the effect of removing the sealing of the opening 3 by the plugging member 4; or directly orienting the plugging member 4 towards the ventilator port so that the ventilator port pierces the plugging member 4, which can also achieve the purpose of removing the sealing of the opening 3 by the plugging member 4. After the ventilator port pierces the plugging member 4, the adsorber 9 is then installed onto the ventilator port in sequence, realizing the conveyance of the air inside the internal pipeline of the ventilator into the cavity 7 of the adsorber 9. At this time, the fragments of the plugging member 4 can be cleaned to prevent the adverse effects of the plugging member 4 fragments on the plugging effect.

[0056] The plugging member 4 can control the timing of the connection between the adsorber 9 and the internal pipeline of the ventilator. It is similar to the plugging member 4 of the container 1, but acts in different stages of the disinfection process, namely the recovery stage.

[0057] The connectors 6 on both the container 1 and the adsorber 9 are adapted to the ventilator port and can cover and shield the exposed part of the ventilator port when mating with the port. On the one hand, it ensures the tight connection between the container 1 and the internal pipeline of the ventilator, and between the adsorber 9 and the internal pipeline of the ventilator, preventing the leakage of disinfectant and the entry of external pollutants; on the other hand, the shielding of the exposed part of the ventilator port provides additional protection, reducing the influence of external factors on the port.

[0058] Traditional disinfection methods often neglect the treatment of the discharged disinfectant after use, resulting in the possibility that the disinfectant may remain in the environment and cause pollution to personnel and the surrounding environment. In this embodiment, through the setting of the adsorber 9, this problem is effectively solved, realizing the effective recovery of the disinfectant and reducing the potential pollution risk.

[0059] It can be understood that after the plugging member 4 is removed from the container 1, the disinfectant inside the container 1 can smoothly enter the internal pipeline of the ventilator by virtue of the positive pressure or natural diffusion in the cavity 2, and utilize the bactericidal characteristics of the disinfectant itself to kill the microorganisms in the pipeline. After the disinfection is completed, the adsorber 9 recovers the discharged disinfectant through the connection with the internal pipeline of the ventilator, relying on the internal adsorption element 8.

[0060] A one-way flow component 5 can also be provided on the adsorber 9, so that the air carrying the disinfectant in the internal pipeline of the ventilator can be discharged from the position of the adsorber 9. After entering the adsorber 9, the disinfectant is absorbed by the adsorber 9, and the air without disinfectant is discharged to the external environment after absorption.

[0061] Activated carbon, high molecular porous materials, etc. can be used as the adsorbent, which can well attach and recover disinfectants such as ethylene oxide and reduce its leakage.

[0062] Embodiment 3

[0063] In another typical embodiment of the present invention, as Figures 1 - 2 shown, a working method of a plugging device for disinfecting the internal pipeline of a ventilator is given. The construction is the same as the plugging device for disinfecting the internal pipeline of a ventilator in Embodiment 1.

[0064] A working method of a plugging device for disinfecting the internal pipeline of a ventilator includes:

[0065] Place the ventilator to be disinfected in a safe environment, install the container 1 at the inhalation port and / or output port of the ventilator. Before or when installing the container 1, change the state of the plugging member 4 to remove the seal of the opening 3 of the cavity 2 by the plugging member 4, so that the cavity 2 communicates with the internal pipeline of the ventilator;

[0066] Let the ventilator stand still, so that the disinfectant in the container 1 enters the internal pipeline of the ventilator for disinfection;

[0067] After the disinfection is completed, clean the residual disinfectant in the internal pipeline of the ventilator and keep the protection of the port by the container 1.

[0068] After the disinfection is completed, perform adsorption treatment on the residual disinfectant in the internal pipeline of the ventilator to reduce the leakage of the disinfectant.

[0069] The above are only the preferred embodiments of the present invention and are not used to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
