The deformation of the valve element (255) is limited so that the inflow port opens only at a specific pressure difference.

A syringe holding structure to which various types of syringes can be easily mounted and which can reliably hold the mounted syringe so that the syringe does not come off. A syringe holding structure (1) is provided with a main adaptor (701) and a sub-adaptor (300) which is detachably mounted to a part of the main adaptor (701). The sub-adaptor (300) is provided with a flange receiver which receives a cylinder flange (211), a flange lock mechanism which locks the cylinder flange when a syringe (200) is rotated 90 degrees about the axis thereof with the cylinder flange received in the flange receiver; and an adaptor affixation mechanism which locks the sub-adaptor to the main adaptor. The sub-adaptor (300) is also provided with an unlocking prohibition mechanism which prohibits the locking effected by the adaptor affixation mechanism from being unlocked while the cylinder flange (211) is locked by the flange lock mechanism.
Disclosed is a medical apparatus that has no risk of a drug such as a contrast agent or saline infiltrating into a housing, and that is easy to clean. An injection head (100) is provided with: a housing (111); and a display unit (50) that displays predetermined information and that is provided to a portion of the housing (111). The display unit (50) has: a light source (26) disposed within the housing (111); and a character display unit (20) that is disposed between the inner surface of the housing (111) and the light source (26), and that causes predetermined characters to be displayed on the surface (31a) thereof. The injection hed (100) is configured in a manner such that, in the state of the light source (26) being lit, said characters can be visually recognized from the outside of the aforementioned housing (111) by means of the light from the light source (26) passing through the housing (111), and in the state of the light source (26) not being lit, the characters can not be visually recognized from the outside of the aforementioned housing (111).
