Abstract
A syringe includes a holding portion that accommodates an injection objective substance, a driving portion that applies injection energy, and a nozzle portion that includes a passage for injection, with these portions being loaded into a housing independently, whereby a state where the injection objective substance can be injected is established. The syringe includes a regulating means for regulating a loading position of the holding portion and the driving portion within the housing so that a loading state, where the holding portion and the driving portion are always loaded in the same order into the housing, is established for injection of the injection objective substance. Due to this, it is possible to facilitate injection of injection liquid ideal for various purposes and to improve user's convenience.
Claims6
A syringe that injects an injection objective substance into an injection target area of a living body, the syringe comprising:
- a housing;
- a holding portion that accommodates the injection objective substance;
- a driving portion that applies injection energy toward the injection objective substance accommodated in the holding portion, from the holding portion, wherein the driving portion includes an ignition charge or a gas generating agent that combusts with a voltage applied from a power source portion and applies the injection energy to the injection objective substance with pressure of a combustion gas that is generated by combustion of the ignition charge or the gas generating agent;
- a nozzle portion that includes a passage, through which the injection objective substance injected from the holding portion flows, and injects the injection objective substance from an open end of the passage to the injection target area, wherein the holding portion, the driving portion, and the nozzle portion are loaded into the housing independently, whereby a state where the injection objective substance can be injected is established;
- and
- regulating means for regulating a loading position of the holding portion and the driving portion within the housing so that a loading state where the holding portion and the driving portion are always loaded in the same order into the housing is established for injection of the injection objective substance, wherein a loading position of the power source portion is not regulated by the regulating means when loading into the housing is implemented.
