Description

Technical Field

[0001] The present invention relates to the field of medical device technology, and more specifically to a device for preventing the splashing of the new coronavirus and reducing the spread of viral aerosols. Background Art

[0002] Infectious diseases are a type of disease caused by various pathogens that can be transmitted between people, animals, or between people and animals.

[0003] An infectious disease is an infection that can be transmitted from one person or other species to another person or species through various routes. Usually, this disease can be transmitted through direct contact with an infected individual, the body fluids and excrement of an infected person, or objects contaminated by an infected person. It can be transmitted through air, water, food, contact, soil, vertical transmission, etc.

[0004] The outbreak of the new coronavirus (named COVID-19) in 2020 has infected a large number of people. After being infected, people will be infected with the new coronavirus pneumonia and need to be isolated. The isolation area is equipped with nursing beds, operating beds, etc. Patients lie on nursing beds or operating beds, and medical staff examine the patients. During invasive intubation or pharyngeal swab collection examinations, some patients may choke or have secretions splashed due to high airway pressure in the patients. This situation may cause infection of medical staff.

[0005] Based on the actual combat on the front line, when patients use ventilators, saliva secretions containing the new coronavirus may splash, causing infection to medical staff. At the same time, it will also cause the formation of high-density new coronavirus aerosols in the isolation space, which may cause medical staff to be splashed with high-titer airway secretions. Medical staff work day and night to develop anti-splash devices, hoping that they can be used to protect medical staff as soon as possible and reduce the infection rate of medical staff who may be caused by rescuing patients with new coronavirus pneumonia.

[0006] The collection of throat swabs is an important test for detecting infection with the new coronavirus. To collect a throat swab, the patient needs to take off the mask and raise his head. The action of opening the mouth means that a large number of droplets carrying the new coronavirus may be generated. In addition, the swab directly stimulates the patient's throat, which may cause the patient to cough and feel nauseous. The droplets sprayed will splash on the mask of the collector, which can easily cause infection to the operator.

[0007] In addition, when patients are sick, local areas will need to be examined and treated. Therefore, a partially opened protective cover can be developed to examine or perform surgery on patients to reduce the spread of the new coronavirus. Summary of the invention

During the check-up, the patient lies on the bed, and the device of the present invention is placed on the bed, covering the patient's head to legs, with part of the patient's legs extending from the notch on the tail cover 2 and a gap reserved to allow air to enter the protective cover.

[0088] like Figure 1-4 As shown, the second opening 71 Figure 4】There are two, and the second full cover plate 4 matched with it is also provided with two. When the patient's head needs to be examined, the medical staff wearing protective clothing, anti-new coronavirus masks and goggles open one of the second full cover plates 4, and extend the detection part of the detection equipment from the second opening 71 into the arch body 1 to detect the patient's head. At this time, the other two first full cover plates 3 are closed. This method can effectively reduce the spread of the new coronavirus in the protective cover to the outside. After the detection is completed, the second full cover plate 4 is sucked on the second opening 71, which is very convenient to operate.

[0089] Embodiment 3:

During the check-up, the patient lies on the bed, and the device of the present invention is placed on the bed, covering the patient's head to legs, with part of the patient's legs extending from the notch on the tail cover 2 and a gap reserved to allow air to enter the protective cover.

[0091] When the chest area of ​​the patient needs to be tested, the medical staff wearing protective clothing, anti-new coronavirus masks and goggles open one of the first full cover plates 3, and the other first full cover plate 3 and each second full cover plate 4 are closed. The medical staff inserts the detection part of the detection equipment from the first opening 11 [ Figure 3 】 Reach into the arched main body 1 to detect the patient's chest area. This method can effectively reduce the spread of the new coronavirus in the protective cover to the outside. After the detection is completed, the first full cover plate 3 is sucked onto the first opening 11, which is extremely convenient to operate.

[0092] Embodiment 4:

[0093] The first type of inspection method for the cover body is as follows: Figure 1-10 As shown, after the patient is infected with the novel coronavirus, regular check-ups are required. During the check-up, the patient lies on the bed, and the device of the present invention is placed on the bed, covering the patient's head to legs, with part of the patient's legs extending from the notch on the tail cover 2 and a gap reserved to allow air to enter the protective cover.

[0094] For throat swab collection, according to actual needs, medical staff wearing protective clothing, anti-new coronavirus masks, and goggles open one of the first full cover plates 3, and the other first full cover plate 3 and each second full cover plate 4 are closed.

[0095] The patient opens his mouth, and the medical staff inserts the swab into the patient's mouth. When the collection is completed, the swab is taken out and the first full cover 3 is closed. This method can effectively reduce the spread of the new coronavirus in the protective cover to the outside. After the test is completed, the first full cover 3 is sucked on the first opening 11, which is very convenient to operate.

[0096] Embodiment 4:

[0097] The first type of ventilator use of the mask body, such as Figure 1-10 As shown, after the patient is infected with the novel coronavirus, regular check-ups are required. During the check-up, the patient lies on the bed, and the device of the present invention is placed on the bed, covering the patient's head to legs, with part of the patient's legs extending from the notch on the tail cover 2 and a gap reserved to allow air to enter the protective cover.

[0098] When the patient is critically ill and needs to use a ventilator, the medical staff wearing protective clothing, anti-new coronavirus masks, and eye masks open one of the first full cover plates 3 or the second full cover plates 4 and the second protective cover 8, and insert the hood and tube body of the ventilator from the arched side hole, and the medical staff fix the hood of the ventilator. After the operation is completed, close the first full cover plate 3 or the second full cover plate 4. Since the second protective cover 8 is a bendable protective cover plate, its elastic force leaves only a small gap in the arched side hole. This method can effectively reduce the spread of the new coronavirus in the protective cover to the outside.

[0099] Embodiment 5:

[0100] The second type of ventilator use of the mask body, such as Figure 3-13 After the patient is infected with the novel coronavirus, regular check-ups are required.

[0102] In addition, the operation in Example 4 is changed to the second mask body in Example 5, and the mask and tube body of the ventilator are operated using the anti-new coronavirus gloves 10. At this time, there is no need to open the first perforated cover plate 30 or the second perforated cover plate 40. This method further effectively reduces the spread of the new coronavirus in the protective cover to the outside.

[0103] Of course, the anti-new coronavirus gloves added to the second type of mask body also have other convenient operations.

[0104] Embodiment 6:

[0105] How disinfectants kill the novel coronavirus: The novel coronavirus is a type of RNA novel coronavirus with an envelope, which has poor heat resistance and its outer envelope is sensitive to organic solvents and disinfectants. Once the envelope is destroyed by the disinfectant, the RNA is also very easy to degrade (for example, the hypochlorous acid produced by sodium hypochlorite in 84 disinfectant in an aqueous solution can decompose new ecological oxygen, which has extremely strong oxidizing properties and can oxidize the nucleic acid of the novel coronavirus), thus inactivating the novel coronavirus.

[0106] like Figure 1 , 3 As shown in FIGS. 4, 12, 13 and 14, a connecting hole 13 is provided in the middle of the arch top of the arch body 1, and the exhaust device 200 is connected to the connecting hole 13 of the arch body through a flange.

[0107] The working principle of the disinfectant disinfection device in the present invention is: fill the disinfectant barrel 203 with an appropriate amount of disinfectant, cover the disinfectant barrel cover and fix the second air duct 204, so that the air outlet of the second air duct 204 is placed below the liquid level of the disinfectant [the present invention places the air outlet of the second air duct 204 below the liquid level of the disinfectant and close to the inner bottom surface of the disinfectant barrel 203].

[0108] In the present invention, the exhaust pump 202 is a one-way exhaust pump, and the exhaust direction thereof can only be output from the first air duct 201 to the second air duct 204 through the exhaust pump 202 .

[0109] The exhaust pump 202 can be designed into multiple wind gear circuits, and medical staff can adjust to the appropriate gear according to actual needs. After the exhaust pump 202 is working, the air in the cover body 100 passes through the first air duct 201, the exhaust pump 202, the second air duct 204, and finally enters the disinfectant barrel 203. The new coronavirus in the cover body 100 will follow the air into the disinfectant and be killed by the disinfectant. The present invention connects the exhaust system to a disinfectant barrel containing a disinfectant that can kill the new coronavirus for filtering to prevent the extracted wind from polluting the surrounding environment.

[0110] A filter is installed at the air outlet of the disinfectant barrel 203. The filter can use an exhaust filter structure similar to a mask for preventing the new coronavirus [such as an N95 mask]. The filter designed here can block the unkilled new coronavirus inside the disinfectant barrel 203. If it is necessary to treat the unkilled new coronavirus, the air outlet is closed and the disinfectant barrel 203 is inverted, so that the inner surface of the filter and the upper wall of the disinfectant barrel 203 can be disinfected and treated for the new coronavirus.

[0111] The exhaust device 200 provided in the present invention discharges the air in the hood body to below the liquid level of the disinfectant in the disinfectant barrel through the operation of the exhaust pump. This design can accelerate the air circulation in the hood body and further reduce the spread of the new coronavirus in the hood body to the outside.

[0112] Embodiment 7:

[0113] The disinfectant disinfection device of the present invention can be replaced by a heatable disinfection device, the replacement part is the disinfectant barrel 203, and the disinfectant barrel 203 is replaced by an electric kettle type heating structure, and the air inlet end of the electric kettle type heating structure is connected to the exhaust device 200. The container of the electric kettle type heating structure is filled with water, and the heating part heats the water to above 56°C.

[0114] Because the new coronavirus can be killed at a temperature above 56°C and heated for at least 30 minutes [the higher the temperature, the shorter the survival time of the new coronavirus].

[0115] First, the electric kettle-type heating structure heats the water inside it to above 56°C and continues to heat it. Then, the air outlet end of the second air duct 204 enters below the water surface, and the exhaust pump 202 is turned on. The new coronavirus enters the water body, and the water temperature is maintained above 56°C to continuously kill the new coronavirus [the higher the temperature, the shorter the survival time of the new coronavirus].

[0116] A filter is installed at the air outlet of the electric kettle. The filter can use an exhaust filter structure similar to that of a mask against the new coronavirus [such as an N95 mask]. The filter designed here can block the unkilled new coronavirus inside the electric kettle. Due to the continuous high temperature inside the electric kettle, the blocked new coronavirus will be killed over time.

[0117] The design of Example 7 can, firstly, accelerate the air circulation within the mask body, and secondly, further reduce the spread of the new coronavirus within the mask body to the outside.

[0118] In summary, the cover body of the device of the present invention is provided with multiple parts of window openings, and medical staff can open the protective cover to examine or operate on the patient. After the operation is completed, the protective cover will cover the opening. The device of the present invention only opens the cover of the part when caring for different areas of the patient in a targeted manner, and the cover of other parts is closed, thereby reducing the spread of the new coronavirus in the protective cover to the outside. The function of the arched side hole is for the cover and tube part of the ventilator to enter. The design of the arched side hole effectively reduces the spread of the new coronavirus in the protective cover to the outside. Anti-new coronavirus gloves are designed on the protective cover. When medical staff examine patients, they do not need to open the protective cover to operate medical equipment, and do not need to directly contact with patients, thereby reducing the risk of infection for medical staff.

[0119] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the contents of the present invention specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
