5results about How to "Ensure sterility" patented technology

The utility model discloses an isolator based on a separated hydrogen peroxide evaporation conveying system, and relates to the technical field of pharmacy. Comprising a vaporized hydrogen peroxide generator, a conveying pipeline, a static pressure cabin and an operation cabin, the static pressure cabin and the operation cabin are arranged in an isolator box body, the vaporized hydrogen peroxide generator is communicated with the static pressure cabin through the conveying pipeline, and the static pressure cabin is communicated with the operation cabin through a circulating filter. The vaporized hydrogen peroxide generator comprises a storage and weighing system, a hydrogen peroxide evaporation system and a high-efficiency filter which are communicated in sequence, the storage and weighing system is used for storing and metering liquid hydrogen peroxide, and the hydrogen peroxide evaporation system is used for heating and vaporizing the liquid hydrogen peroxide; feeding into the static pressure cabin through a high-efficiency filter and a conveying pipeline; by designing the separated hydrogen peroxide evaporation conveying system, the equipment size and sanitation dead angles are reduced, and the pollution risk of a hydrogen peroxide evaporation device to a clean area is reduced.

This utility model relates to the field of plastic packaging technology and discloses a secondary-sealing packaging box, comprising: a box body, the box body having a receiving cavity for accommodating syringes, filter needles, injection needles, and vials; the opening of the box body has a primary sealing area and a secondary sealing area, the primary sealing area corresponding to the area within the receiving cavity for accommodating syringes, filter needles, and injection needles, and the secondary sealing area corresponding to the area within the receiving cavity for accommodating vials; the primary sealing area and the secondary sealing area are independent of each other, allowing the sealing film to first cover and seal the primary sealing area, while the secondary sealing area remains open and is resealed by the sealing film after the vials are inserted. This utility model forwards the most cumbersome instrument sorting and assembly process to the instrument supplier, requiring the pharmaceutical factory to only perform the secondary sealing step, effectively solving the problem of the need for additional assembly work by pharmaceutical factories.

The utility model relates to the technical field of cell culture, and specifically discloses an online sterile filtering device for cell culture medium, which comprises: a liquid preparation mechanism; a filtering mechanism, which comprises a first filter and a second filter, the first filter is connected to the liquid preparation mechanism through a first pipeline, the first filter is connected to the second filter through a second pipeline, the second filter is externally connected to a third pipeline, and the first filter and the second filter are provided with filter cores; the third pipeline is connected to a first reactor; a functional mechanism, which comprises a steam pipeline connected to the first pipeline; and a control mechanism connected to the liquid preparation mechanism, the first filter, the second filter and the steam pipeline. The utility model realizes complete sterility of the second filter, and overcomes the defects of pollution hazards and incomplete cleaning in the online filtering of the cell culture medium in the prior art.

This invention relates to the field of medical device technology, and particularly to a centrifuge adapted for the preparation of centrifuge tubes for clinical cell mitochondrial extraction. The centrifuge includes: a centrifuge body, a centrifuge lid hinged to one side of the centrifuge body, a platelet detection device fixedly disposed on the side of the centrifuge lid away from the centrifuge body, and a liquid aspiration device rotatably disposed on the side of the centrifuge lid near the centrifuge body. A lid locking mechanism is fixedly disposed on the side of the centrifuge body near the centrifuge lid, and a locking hook is fixedly disposed on the side of the centrifuge lid near the centrifuge body, the locking hook matching the lid locking mechanism. This invention avoids the variability caused by human operation during multiple supernatant extractions, reduces the possibility of contamination from human operation, ensures the sterility and component stability of the extraction process, and greatly improves the efficiency and success rate of mitochondrial extraction.
