  • Patent number: 6808507
    Abstract: A simple mechanism that provides the manipulations required to deliver a correct injection and also incorporates the safety modifications that are needed to prevent needlestick injury and ensure self destruct capability. A surprisingly simple and cheap modification to a sterile package for the standard syringe and needle can successfully be used to automate the medical skills needed to deliver a safe injection and dispose of the hazardous needle afterwards. The sterile package consists of a housing for the syringe barrel, which can telescope into a larger diameter hollow cap covering the syringe plunger. The syringe and needle are located fully inside this two-part packaging sheath, which completely encloses and protects them.

  • Publication number: 20030113900
    Abstract: This invention provides methods of drying and stabilizing prokaryotic cells, and the compositions obtained thereby. The cells are first cultured or incubated under conditions sufficient to induce intracellular trehalose, suspended in a stabilizing solution and dried to form a solid glass. The resulting product is storage-stable at room temperature, showing little viability loss on storage.
