Description

Technical Field

[0001] The present invention is a technology for joining and separating a shielding film for an isolation space and a shielding film for a protective space used as a protective suit for working inside a space that confines harmful substances floating in the air, while avoiding the influence of a filling object in the shielded internal space.

Background Art

[0002] Poisonous substances diffused in the air such as toxic gases, bacteria, and radioactive dust are a threat to people. With globalization, it has been repeated that a virus generated somewhere on the earth has spread worldwide, becoming a major threat to humanity. As a countermeasure against viruses, it is necessary to isolate the infected people who are the source of infection and prevent transmission while curing them. In addition, a sealed treatment room is required for the treatment of patients. Regarding entry and exit to and from the treatment room, medical staff who have received special training on putting on and taking off protective clothing are limited to doing so, so the burden on medical staff has increased with the spread of the virus. There is a demand for a protective clothing production technology that allows ordinary people to safely and easily enter and exit the shielding space without receiving special training.

Summary of the Invention

Problems to be Solved by the Invention

[0004] Tools and protective clothing for entering and exiting a shielding space where toxic substances float without being exposed to the toxic substances have been proposed. Patent Document 1 proposes a composite slider that can be used for a protective suit for an isolation space.

[0005] The composite slider described in Patent Document 1 was conceived with the purpose of joining or separating the spaces enclosed by each of the two zippers. If one of the enclosed spaces, closed by the zipper, is used as protective clothing, it is possible to safely perform work inside a space containing hazardous substances. However, the composite slider shown in Patent Document 1 cannot avoid the possibility of being affected by hazardous substances in the shielded space because the zipper, once the teeth are released, is open to the isolated space. In addition, the device is complicated to operate, and it takes time to put on and take off the protective clothing. [Means for solving the problem]

[0006] This invention provides a protective suit device and method that allows for safe and easy entry and exit into a shielded space where toxic substances are suspended, by easily changing the combination and joining of fasteners that close the shielding space membrane and the protective space membrane.

Front end entrance section (27) Therefore, the protective space, which was previously separated within the shielded space, becomes connected to the external space. As shown in Figure 11, the protective space is shaped like a protective suit and is attached to the inside of the shielding space membrane. space separation junction Composite slider (6) Attach it to, space separation junction Composite slider (6) Lowering the temperature creates a connection between the protected space and the atmosphere, allowing entry and exit from the atmosphere to the protected space. When a worker enters the protected space, space separation junction Composite slider (6) A holder for separating and joining the tip in different spaces. (7) After setting it, the slider on the protective space side (1) A holder for separating and joining the tip in different spaces. (7) When moved away, the protective space shielding membrane becomes a fully covered protective suit. (20) It can be used as protective clothing. (20) This is an easy-to-use inter-space tip-to-join holder. (7) Because it can be attached and detached using this method, it allows for safe and repeated work within the isolated space.

[0010] The assembly and usage of the device will be explained step by step. As shown in Figure 11, the assembly of the device involves attaching the isolation space shielding membrane to a structure (not shown) that has been pre-installed at the entrance / exit points of the isolation space and the protective space, followed by the separation and joining holder for the different space front end shown in Figure 2.

(7) and space separation junction Composite slider (6) in front tip Entrance (27) Between these two points, as shown in Figure 10, the protected space within the isolated space is connected to the atmospheric space. By making the length of this connection sufficient for people to enter and exit, the protected space can be allowed to enter the isolated space without being affected by the harmful substances in the isolated space. Once inside the protected space, space separation junction Composite slider (6) of different space tip decoupling Holder (7) Return to and protect space Side slider (1) The system is disconnected, and work is carried out inside the isolated space. After the work is completed, protective measures are taken. space Side slider (1) A holder for separating and joining the tip in different spaces. (7) Put it back and tighten the handle (23) Rotate it The protective space side slider (1) and the shielding space side slider (2) Combine both sliders into one. space separation junction Composite slider (6) A holder for separating and joining the tip in different spaces. (7) Move away from the surroundings, connect the protective space to the atmospheric space, and exit into the atmospheric space. [Effects of the Invention]
