Claims (30)

1. An actuator adapted to form a needleless injector in conjunction with an ampoule pre-filled with fluid for insertion into the object and provided with a fluid outlet and a free piston in contact with the fluid, containing a spring-loaded hammer and temporarily retained by the retainer, made with the ability to move in the first direction under the action of the force of the spring to strike the free piston and the subsequent movement of the piston in the first direction to displace the dose dkosti through liquid outlet, wherein the spring is integrated energy source and is adapted to transition from a state with a high energy content to a state with low energy content, but not vice versa.  2. The actuator according to claim 1, wherein a compression spring is used as a spring.  3. The actuator according to claim 1, wherein a gas spring formed by a pressurized gas placed with the possibility of applying a force to a hammer, is used as a spring, and the lock serves to temporarily prevent the movement of the hammer under the action of said force.  4. The actuator of claim 3, wherein air is used as the gas.  5. The executive mechanism for PP. 1-4, containing a trigger device designed to control the latch and thus start the injection only after reaching a predetermined contact force between the hole in the ampoule for the fluid to exit and the object.  6. The actuator according to claim 5, comprising a part configured to be held by the consumer, and means for installing the ampoule to move said part, made to hold it by the consumer, relative to the ampoule as a result of pressing the opening of the ampoule to exit the liquid to the object, moreover, the specified latch contains the item made with the possibility of movement caused by the specified relative mutual displacement of the specified part, made with the possibility of holding it for bitelem, and ampoules from the position in which the specified part keeps the drummer from moving, to the position in which it allows the movement of the drummer.  7. The actuator according to claim 6, wherein said part of the retainer is made elastic.  8. The executive mechanism for PP. 1-7, in which the energy supply of the specified spring is sufficient to displace a single dose of fluid.  9. The executive mechanism for PP. 1-7, in which the energy supply of the specified spring is sufficient to displace successive doses of fluid.  10. The executive mechanism for PP. 1-9, made with the possibility of using the compound in an ampoule, which separately contains components intended to be mixed with each other before injection, and containing mixing means, made with the possibility of mixing the components with each other when using these tools.  11. The actuator according to claim 10, adapted to be used with an ampoule having compartments separated by at least one partition, and a piercer installed therein with the possibility of moving to the mixing position, in which it pierces this partition or each partition, the mixing element is adapted to move the piercer to the mixing position.  12. The actuator according to claim 1-11, in which the indicated dose is unchanged.  13. The actuator of claim 1-12, comprising means for varying said dose.  14. The actuator according to claim 1-13, containing means for installing the ampoule with the possibility of its extraction.  15. The combination of the actuator according to claim 14 with the ampoule installed in it with the possibility of its extraction.  16. The combination of the actuator in PP. 1-13 with an ampoule fixed in it.  17. The combination of PP. 15 and 16, in which the ampoule has a body made of glass.  18. The combination according to claim 17, in which the glass is transparent.  19. Combination on PP. 15-18, in which the free piston of the ampoule contains plastic.  20. A combination according to claim 19, wherein a polymer or a copolymer containing a hydrocarbon fluoride is used as the plastic.  21. A combination according to claim 19, wherein polytetrafluoroethylene is used as the plastic. 22. The combination according to claim 19, in which the specified plastic is selected from the group including
tetrafluoroethylene and hexafluoropropylene copolymer, tetrafluoroethylene and ethylene copolymer, polychlorotrifluoroethylene, polyvinylidene fluoride, tetrafluoroethylene and perfluoro (or propyl vinyl) copolymer and hexafluoroisobutylene and vinylidene fluoride copolymer.  23. Ampoule for use in conjunction with an actuator to form an injector, comprising a body made of glass and a piston mounted for movement in the body and containing a material that is substantially inelastic with a slow application of force, but very elastic with fast application of force.  24. Ampoule under item 23, in which the glass is made transparent.  25. Ampoule under item 23 or 24, in which the piston contains plastic.  26. Ampoule on p. 25, in which the quality of plastics used polymer or copolymer containing hydrocarbon fluoride.  27. Ampoule according to claim 25, in which polytetrafluoroethylene is used as the plastic.  28. Ampoule according to claim 25, in which said plastic is selected from the group comprising a copolymer of tetrafluoroethylene and hexafluoropropylene, a copolymer of tetrafluoroethylene and ethylene, polychlorotrifluoroethylene, polyvinylidene fluoride, a copolymer of tetrafluoroethylene and perfluoro (or propylene vinyl), and a group of tehrytrs, or a group of tehpidryrs, or a group of temperes, and a set of tehpriters, and a group of tehmers, or a piece of tehpriters, and a set of tehpriters, and a set of tehpriters, and a set of tehpriters, and a set of tehrimer, and a set of tehpriters, and a piece of tehpramer;  29. Ampoule for use in conjunction with an actuator to form an injector, comprising a body made of glass and a piston mounted for movement in the body and containing polytetrafluoroethylene.  30. A method of manufacturing a combination of PP. 15-22, including pre-compression of the spring of the actuator and the installation of the ampoule in the actuator.
