Claims (12)

1. Безыгольный инъектор, содержащий первую часть, которую держит пользователь, вторую часть, имеющую выпускное отверстие для жидкости, инъектируемой в организм, и раздаточный элемент, установленный с возможностью перемещения для выталкивания жидкости через выпускное отверстие под действием силы пружины, обеспечивающей запас энергии, при этом первая и вторая части установлены подвижно друг относительно друга, а инъектор содержит демпфирующее средство, имеющее вязкую демпфирующую среду для демпфирования движения первой части относительно второй.1. A needleless injector containing the first part that the user holds, the second part having an outlet for fluid injected into the body, and a dispensing element mounted to move to push the fluid through the outlet under the action of a spring force that provides energy reserve, the first and second parts are mounted movably relative to each other, and the injector comprises a damping means having a viscous damping medium for damping the movement of the first part of the relative but the second. 2. Устройство по п.1, содержащее патрон, внутри которого находится жидкость и свободный поршень, контактирующий с жидкостью, при этом раздаточный элемент выполнен в виде ударного элемента, на который действует пружина и который временно удерживается задвижкой, и установлен с возможностью перемещения в первом направлении под действием силы пружины, сперва ударяя по свободному поршню и затем продолжая перемещать его в первом направлении для выталкивания дозы жидкости через выпускное отверстие. 2. The device according to claim 1, containing a cartridge, inside which there is a liquid and a free piston in contact with the liquid, while the dispensing element is made in the form of a shock element, which is acted upon by a spring and which is temporarily held by a valve, and is mounted with the possibility of movement in the first direction under the action of the spring force, first striking the free piston and then continuing to move it in the first direction to push the dose of fluid through the outlet. 3. Устройство по п.2, в котором задвижка установлена с возможностью ее освобождения в результате перемещения первой части относительно второй части в указанном первом направлении. 3. The device according to claim 2, in which the valve is installed with the possibility of its release as a result of the movement of the first part relative to the second part in the specified first direction. 4. Устройство по любому из предыдущих пунктов, в котором демпфирующее средство содержит канавку, которая выполнена в одной из указанных частей и в которой находится вязкая демпфирующая среда, и элемент, выполненный на другой из этих частей, для перемещения, при пользовании устройством, в вязкой демпфирующей среде с обеспечением демпфирования. 4. The device according to any one of the preceding paragraphs, in which the damping means comprises a groove that is made in one of the indicated parts and in which the viscous damping medium is located, and an element made on the other of these parts to move, when using the device, in the viscous damping environment with damping. 5. Устройство по любому из предыдущих пунктов, в котором вязкой демпфирующей средой является консистентная смазка. 5. The device according to any one of the preceding paragraphs, in which the viscous damping medium is a grease. 6. Устройство по любому из пп.1-4, в котором вязкой демпфирующей средой является масло. 6. The device according to any one of claims 1 to 4, in which the viscous damping medium is oil. 7. Устройство по любому из пп.1-4, в котором вязкой демпфирующей средой является воздух. 7. The device according to any one of claims 1 to 4, in which the viscous damping medium is air. 8. Устройство по любому из пп.1-4, в котором демпфирующее средство включает цилиндр и поршень, образующие буфер. 8. The device according to any one of claims 1 to 4, in which the damping means includes a cylinder and a piston forming a buffer. 9. Устройство по любому из пп.1-4, в котором демпфирующее средство содержит устройство, имеющее по меньшей мере одну лопасть, вращающуюся в вязкой демпфирующей среде. 9. The device according to any one of claims 1 to 4, in which the damping means comprises a device having at least one blade rotating in a viscous damping medium. 10. Устройство по любому из предыдущих пунктов, в котором пружина является механической пружиной. 10. The device according to any one of the preceding paragraphs, in which the spring is a mechanical spring. 11. Устройство по любому из пп.1-9, в котором в качестве пружины используется сжатый газ. 11. The device according to any one of claims 1 to 9, in which compressed gas is used as a spring. 12. Исполнительный механизм, выполненный с возможностью образования, в сочетании с патроном, безыгольного инъектора по п.2 или по любому из пп.3-11, зависимых от п.2, без патрона. 12. An actuator configured to form, in combination with a cartridge, a needleless injector according to claim 2, or according to any one of claims 3-11, dependent on claim 2, without a cartridge.
