1188 results about "Radiation protection" patented technology

Radiation protection, also known as radiological protection, is defined by the International Atomic Energy Agency (IAEA) as "The protection of people from harmful effects of exposure to ionizing radiation, and the means for achieving this". Exposure can be from a source of radiation external to the human body or due to internal irradiation caused by the ingestion of radioactive contamination.

Radioprotective compound coating for medical devices

Medical devices, and in particular implantable medical devices, may be coated to minimize or substantially eliminate a biological organism's reaction to the introduction of the medical device to the organism. The medical devices may be coated with any number of biocompatible materials. Therapeutic drugs, agents or compounds may be mixed with the biocompatible materials and affixed to at least a portion of the medical device. These therapeutic drugs, agents or compounds may also further reduce a biological organism's reaction to the introduction of the medical device to the organism. In addition, these therapeutic drugs, agents and/or compounds may be utilized to promote healing, including the formation of blood clots. Also, the devices may be modified to promote endothelialization. Other compounds may include those that prevent damage from ionizing radiation. Various materials and coating methodologies may be utilized to maintain the drugs, agents or compounds on the medical device until delivered and positioned. In addition, the devices utilized to deliver the implantable medical devices may be modified to reduce the potential for damaging the implantable medical device during deployment. Medical devices include stents, grafts, anastomotic devices, perivascular wraps, sutures and staples. In addition, various polymer combinations may be utilized to control the elution rates of the therapeutic drugs, agents and/or compounds from the implantable medical devices.

SMD (surface mounted device) with cooling and electromagnetic wave absorption functions and preparation method and application thereof

Aiming at the problems existing in the present cooling and radiation protection technologies of electronic products, the invention provides an SMD (surface mounted device) with cooling and electromagnetic wave absorption functions, which is applied to electronic equipment. The SMD comprises a decoration layer, a cooling and electromagnetic wave absorption layer for cooling and electromagnetic wave absorption and a mounting layer, wherein the cooling and electromagnetic wave absorption layer is arranged between the decoration layer and the mounting layer. The SMD further comprises a protective stripping layer which is arranged below the mounting layer and used for protecting the adhesiveness of the mounting layer, and the stripping layer is taken off before the SMD is used, and then the SMD is mounted at a position needing cooling and electromagnetic wave absorption. Furthermore, the cooling and electromagnetic wave absorption layer is of a structure consisting of more than two layers, including a cooling layer and an electromagnetic wave absorption layer which are independent from each other; accordingly, the cooling and electromagnetic wave absorption layer can be a single-layer structure and is made of a material with cooling and cooling and electromagnetic wave absorption functions. The invention also provides the preparation and application methods of the SMD. The SMD with cooling and electromagnetic wave absorption functions is applied to a shell of electronic equipment, and the shell of the electronic equipment includes but is not limited to a mobile phone shell, a network card, a panel personal computer shell hot spot, a netbook shell hot spot, notebook computer shell hot spot, game equipment and other consumer mobile equipment can improve cooling effect, reduce temperature and weaken electromagnetic wave radiation.

Decellularization cornea preparation method

ActiveCN103908700AKeep active ingredientsBe transparentProsthesisTransplanted corneaAntigen
The invention relates to a decellularization cornea preparation method, which adopts steps of corneal epithelium layer removing, ultraviolet cross-linking, viral inactivation, decellularization treatment, gradient dehydration, radiation protection and sterilization. According to the present invention, the prepared decellularization cornea has characteristics of complete antigen removing, no excitation of host acquired immunity reaction, good biocompatibility, low damage on nature corneal stroma, maintaining of structure characteristics of the nature corneal, and maintaining of effective components of the nature corneal so as to provide physical and chemical properties similar to the nature corneal; and after the prepared decellularization cornea is transplanted, animal experiment results show that characteristics of transparent transplanted cornea, no scar formation, no melting generation and no neovascularization are provided, the transplanted cornea and the recipient bed are completely integrated after transplanting a month, the transplanted cornea is subjected to complete epithelization after three months, corneal stroma cells migrate toward the decellularization cornea graft so as to prove that the tissue just takes place slow reconstruction, and the transplanted cornea after 6 months does not show significant difference in histology and appearance detection compared with the nature cornea.
