[0078] figure 1A schematic structure of the isolator 100 shown as the first embodiment is shown. As shown in the figure, the isolator 100 is provided with: an operation chamber 10 for performing operations of extracting cells and culturing cells from living body-derived materials; a gas supply unit 40 for supplying gas to the operation chamber 10; The gas exhaust unit 50 for the gas in the chamber 10, the sterilizing substance supply device 200 for supplying the sterilizing substance to the operation room 10, and the control unit 90 for controlling these components. In addition, a material derived from a living body refers to a material containing a living thing itself including cells, a substance constituting a living being, or a substance produced by a living being.

[0079] The gas supply unit 40 is provided with an air intake port 42 , a three-way valve 44 , and cooling fins 46 . Air is sucked in from the outside through the suction port 42 . The three-way valve 44 is c...

[0141] The structure of the isolator 100 described as the second embodiment is similar to the structure of the isolator 100 of the first embodiment, and the difference from the first embodiment is that the normal line of the vibrating plate 2141 of the sterile gas generating device 202 is opposite to tilted in the vertical direction. Figure 5 The configuration of the sterile gas generator 202 described as the second embodiment is shown. This figure is a cross-sectional view of the sterile gas generator 202 viewed from the side.

[0142] As shown in the figure, in the sterile gas generator 202 according to the second embodiment, the normal direction of the center of the vibrating surface of the vibrating plate 2141 is inclined with respect to the vertical direction. Thus, by inclining the vibration plate 2141 relative to the vertical direction, it is possible to effectively suppress the formation of bubbles (bubbles when the ultrasonic transmission material 240 is water) that...

[0145] The structure of the isolator 100 described as the third embodiment is similar to the structure of the isolator 100 of the first embodiment, but the structure of the heater 222 and the cooling fin 223 of the sterilization gas generator 202 is different from the first embodiment. Figure 7 The configuration of the sterile gas generator 202 described as the third embodiment is shown. This figure is a cross-sectional view of the sterile gas generator 202 viewed from the side.

[0146] In the first embodiment, the heater 222 which is a heat generating body is provided inside the heating pipe 221, but in the third embodiment, the heater 222 is not provided inside the heating pipe 221 but only the radiator fins 223 are arranged. In this structure, the heater 222 is provided outside the heating pipe 221 around the side surface of the heating pipe 221 . The cooling fins 223 are provided on the shaft member 2231 extending in the vertical direction of the heating tube 221 . The...

Abstract

The invention relates to an isolator and a sterile substance supplying apparatus for the isolator, which reduces the the time required for sterilization treatment and increases the work efficiency of the isolator. The sterile substance supplying apparatus (200) comprises a a sterile gas generation portion (202) composed of an atomization portion (210) and a gasification portion (220). The atomization portion (210) atomizes the hydrogen peroxide in a cup (214) by the ultrasonic vibration generated by an ultrasonic wave vibrator (231). The atomized hydrogen peroxide is heated by a heater (222) in the gasification portion (220) and furthermore gasified. The gasified hydrogen peroxide is used as the sterile gas to be supplied on an operation chamber (10) of the isolator. (100).

Description

technical field [0001] The invention relates to an isolator and a sterilizing material supply device for the isolator. Background technique [0002] The isolator has an operation room in a sterile environment inside, and the operation room is used for operations requiring a sterile environment, for example, operations for materials derived from living organisms such as cell culture. Here, the term "sterile environment" refers to an environment that is infinitely close to sterility in order to avoid contamination of substances other than those necessary for operations performed in the operating room. In addition, the term "sterilization treatment" means a treatment for realizing the aseptic environment, and a substance used for the sterilization treatment is called a sterilizing substance. [0003] The operation room has a gas supply port and a gas discharge port, air is supplied into the operation room from the gas supply port, and air is discharged through the gas discharg...
