Abstract: There is provided an X-ray utilized compound measuring apparatus in which troublesome tasks required to dispose a measurement object are reduced and the accuracy or the validity of measurements on multiple kinds of measurement can be improved.

Abstract: A method of using a medicine injection device including a syringe filled with a medicine; a needle tube having a needle tip for puncturing the skin; a flange-like skin contact portion that is disposed in a manner so as to cover an area surrounding the needle tube and makes contact with and/or faces the skin when the living body is punctured with the needle tube; and an absorption part that is disposed in the skin contact portion of the needle hub. The method includes removing air from the medicine injection device prior to injection of the medicine, whereby medicine spilled from the needle tip is caught in the skin contact portion; the absorption part absorbing the spilled medicine staying in the skin contact portion; positioning the skin contact portion adjacent the skin; puncturing the skin with the needle tip; and injecting medicine from the needle tip into the skin.

Abstract: An information processing device includes a first port and a processor coupled to the first port and configured to transmit, via the first port, a first signal to a first device coupled to the first port, cause a second device coupled to the first port to determine whether a failure is present in the first port when the information processing device does not receive a first response signal in response to the first signal, and determine that the failure is present in the first device when the second device does not determine that the failure is present in the first port.

Abstract: A syringe package contains a prefilled syringe system including a prefilled syringe that includes a syringe body that is filled with a drug, a gasket located in the syringe body, and a plunger partially disposed in the syringe body. The syringe package includes: a package body that houses the prefilled syringe; and a support that is disposed inside the package body and that supports the prefilled syringe.
