  • Patent number: 7337511
    Abstract: A biological hazard protection body bag comprises an non-transparent outer bag case and a transparent inner bag case, which transparent inner bag case provides a vacuum filtration device formed by a check valve and medical grade filter screen for achieving a vacuum state inside the inner space of the transparent inner bag case by air suction through the check valve of the vacuum filtration device, and the air extracted from the inner space of the transparent inner bag case is completely filtrated by the medical grade filter screen to prevent the pathogen from being extracted from the inner space of the transparent inner bag case to isolate the corpse inside the transparent inner bag case under nearly vacuum state with gastight bag case construction to achieve the purpose of prevent infection or dissemination of pathogen.

  • Publication number: 20040238397
    Abstract: An innovated structure of biological protection collecting bag, having a medical grade filter screen installed inside the collecting bag, allowing free air flow into and out of the bag, thereby completely filtering and arresting pathogens inside the bag. Meanwhile, the bag opening is sealed by a plurality of airtight sealing strips, so the user can quickly and hermetically seal the bag without having to squeeze on the collecting bag, thereby effectively preventing pathogens from contaminating the ambient environment during handling and stacking processes.

  • Publication number: 20040007904
    Abstract: A protecting medical-treatment chair which can generate a protective air curtain and a negative air pressure inside the chair by applying the suction and discharging effect generated by the medical level air-suction and cleaning equipment to make the user of the protecting medical-treatment chair isolated and prevent contact between the user of the chair and the air outside the chair; particularly, by applying the push and pull effect of the air flow the air exhaled by the user of the chair can be sent to the medical level air-suction and cleaning equipment for filtration and sterilization, and than the clean air are discharged from the air suction and cleaning equipment for recirculation and generating the air-curtain shield by the protecting medical-treatment chair.
