Description

Technical Field

[0001] The utility model belongs to the field of operating instruments, and in particular relates to a portable glove tester. Background Art

[0002] Work performed in a clean atmosphere, such as work in the manufacturing stage of pharmaceuticals or work in the manufacturing stage of semiconductors and electronic components, is performed in a clean working environment that keeps the interior sterile / dust-free to prevent contaminants from entering from the external environment. As such a working environment, a clean room is usually used. In the clean room, workers wearing dust-free clothing perform work. However, in order to improve the sterility and dust-free assurance levels, a more highly clean area is formed in the clean room for work.

[0003] As a method of forming a highly clean area, an isolator or a glove box (hereinafter collectively referred to as an "isolator") is used. The isolator uses a chamber that is sealed from the external environment, and the operator works from the outside of the chamber through work gloves, etc. This type of isolator is particularly called a sterile isolator.

[0004] In addition, as another method of forming a highly clean area, a RABS (Restricted Access Barrier System) is used. The RABS is an area surrounded by a wall surface whose lower part is released in a part of the clean room, and a laminar flow of clean air flowing from the upper side to the lower side is circulated inside the area, and strict entry restrictions are imposed on operators. In the RABS, operators work through work gloves and the like set on the wall surface.

[0005] On the other hand, in operations involving handling substances that may affect the human body, such as operations at the manufacturing stage of pharmaceuticals, operations involving handling highly toxic microorganisms in the medical or biological fields, or operations involving handling radioactive substances, it is necessary to protect the operator from contamination by chemical substances or microorganisms that may affect the human body, and it is also necessary to prevent these chemical substances or microorganisms that may affect the human body from leaking from the operating environment to the external environment. In such operations, isolators are also used that allow operations to be performed from the outside of a chamber through gloves or a half-suit, and the chamber is sealed from the external environment. Such isolators are particularly referred to as closed isolators.

[0006] The isolator is hermetically isolated from the external environment where the operator works, and the external air is purified by a filter and supplied to the chamber, and the air in the chamber is purified by a filter and discharged to the outside. Therefore, this isolator can basically be used as both a sterile isolator and a closed isolator.

[0007] In addition, when using an isolator, the safety can be further improved by adjusting the air pressure in the chamber according to the purpose. That is, when used as a sterile isolator, the air pressure in the chamber is made higher than the air pressure outside (hereinafter referred to as positive pressure), so that even if leakage occurs from the chamber, since air flows from the chamber side to the outside, floating bacteria and the like will not invade the chamber from the outside.

[0008] On the other hand, when used as a closed isolator, the pressure inside the chamber is made lower than the external air pressure (hereinafter referred to as negative pressure). Therefore, even if leakage occurs from the chamber, the chemical substances in the chamber will not pollute the external environment because the air flows from the outside into the chamber.

[0009] Here, in order to maintain a highly sterile environment inside the sterile isolator or RABS at the boundary between the inside and the outside, the airtightness of the work gloves is considered to be particularly important. In work gloves frequently used by workers, holes (pinholes) or cracks are generated in the main body, which destroys the airtightness and makes it impossible to maintain a highly sterile environment inside.

[0010] On the other hand, in order to protect workers from contamination by chemical substances or microorganisms that may affect the human body at the boundary between the closed isolator and the outside, the airtightness of work gloves is considered to be particularly important. If holes (pinholes) or cracks are generated in the main body of the work gloves, the airtightness is destroyed, and chemical substances or microorganisms that may affect the human body leak into the external environment and contaminate the workers.

[0011] Therefore, it is preferred to accurately record the use conditions of work gloves, such as the use frequency, use period, and work content, and perform airtightness inspection or replacement of work gloves based on a given rule. However, in practice, the management of work gloves is mainly carried out by inspecting work gloves for damage after a certain period of time.

[0012] The integrity of gloves will have a crucial impact on the production risk and the safety isolation of personnel. Therefore, various air tightness inspection devices (generally called "glove testers") were used. However, most of the existing glove testers are divided into two parts: a chassis and a test plate. In addition, an external air source is required, which results in large equipment size, cumbersome use, and inconvenient portability. Utility Model Content

When the pressure drops to the detection pressure, the countdown begins. The pressure sensor detects the pressure drop per unit time.
