A device for administering a fluid can include a cylinder, a piston connected to a piston rod, and a tensioning device connected to the piston rod. The tensioning device includes a ramp which is rotatable via a motor, a ramp track, and a roller which is in contact with the ramp track and which is mounted rotatably in a driver. The driver can be connected to the piston rod via a joint. In a tensioning procedure, the ramp track is rotated such that the roller runs on the region of inclination as far as the second plateau and the piston is thereby moved to its rear end position. In a dispensing procedure, the ramp track is rotated until the roller runs over a transfer region and, on account of the tensioning, is accelerated toward the first plateau and, as a result, the piston is moved toward the an dispensing end.

Device for administering a fluid

A device for administering a fluid can include a cylinder, a piston displaceable in the cylinder and connected to a piston rod, and a tensioning device connected to the piston rod. The tensioning device includes a ramp rotatable via a motor, and a ramp track extending along a helical line. The tensioning device includes a roller which is in contact with the ramp track. To perform a tensioning procedure, the ramp track is rotated such that the roller runs on the region of inclination as far as the second plateau so the piston is moved to its rear end position. To perform a dispensing procedure, the ramp track is rotated until the roller runs over a transfer region and is accelerated toward the first plateau, thereby the piston is moved toward an open dispensing end. A control unit determines whether the tensioning procedure and/or dispensing procedure has taken place correctly.

A device for administering a fluid can include a cylinder, a piston connected to a piston rod, and a tensioning device connected to the piston rod. The tensioning device includes a ramp which is rotatable via a motor, a ramp track, and a roller which is in contact with the ramp track and which is mounted rotatably in a driver. A dose setting means can be provided which comprises a spacer and a movement unit. The movement unit can move the spacer from a neutral position into an active position between the driver and the cylinder such that the driver is stopped by the spacer and therefore the piston stroke during the movement of the piston to the open dispensing end is shorter in comparison to the case in which the spacer is in its neutral position.

In a dispensing procedure, a ramp track is rotated until a roller runs over a transfer region and is accelerated toward the first plateau and, as a result, the piston is moved toward an open dispensing end. The ramp track runs on the face side of a wall extending along a circular path. A cover engages over the ramp track, the driver and the roller and has at least one scraper extending counter to the first direction and extending within the wall as far as the inner side of the wall, and thus scrapes off lubricant located on the inner side from the inner side.

A device for administering a fluid is provided, with The tensioning device (S) has a ramp () which is rotatable by means of a motor () and has a ramp track () extending along a helical line, wherein the ramp track () ascends from a first plateau along a region of inclination (S, S) to a second plateau and descends from the second plateau to the first plateau via a transition flank (). The tensioning device (S) furthermore has a roller () which is in contact with the ramp track () and is mounted rotatably in a driver (), which is connected to that end of the piston rod () which protrudes out of the cylinder (), and therefore, upon rotation of the ramp (), the ramp track () runs below the roller (), which thereby rotates, wherein the roller () has a support region () which rests on the region of inclination (S, S) of the ramp track (), and at least one laterally adjoining side region () which has a smaller outside diameter than the support region () and which does not rest on the region of inclination (S, S) of the ramp track (), wherein, during rotation of the ramp, both the support region () and the side region () come into contact with an edge () of the ramp track (), said edge connecting the second plateau to the transition flank ().

Injector

An injection device for administration of an injection to an animal can include a main body, which contains an injection instrument, a contact device, which has a contact area which is shaped in conformity with a body part of the animal to which the injection is to be administered. A support device which supports the contact device on the main body can be movable in a pressure application direction. A force measurement device including at least one force sensor can be designed to measure at last one force with which the contact device acts on the main body. A control device can activate the injection instrument if the force measured by the force measurement device lies in a specified range.

A syringe includes a first syringe barrel and a second syringe barrel. Each barrel includes a delivery end to which an end piece with a channel is secured, a piston which is arranged movable in the syringe barrel and can be moved towards the delivery end in order to deliver a fluid located between the delivery end and the piston via the channel. The two syringe barrels are mechanically connected to each other such that the distance between them cannot be changed. At least one of the two end pieces can be secured to the allocated delivery end in different positions for adjustment of the distance between the two channels.

A connecting module is provided with a first connecting component, which has a first fluid channel and a first contact surface, a second connecting component, which has a second fluid channel and a second contact surface. One of the two contact surfaces is formed as an inner surface and the other of the two contact surfaces is formed as an outer surface which is complementary to the inner surface. The connecting module further includes a receiving sleeve with a first threaded section and a first connecting device for the first connecting component. The first connecting component has a second connecting device, which interacts with the first connecting device in such a way that the first connecting component is detachably connected to the receiving sleeve. The second connecting component has a second threaded section which is complementary to the first threaded section.

An orthopedic screw fastener system, includes at least one screw, consisting in each case of a screw head and of a screw shank, the screw head being provided with a thread, and at least one plate with a thickness, provided with at least one through-bore which is able to receive a screw. The plate has a through-opening, formed by at least two through-bores, each through-bore being defined by a midpoint and by a radius, and the through-bores are offset relative to each other and intersect each other in such a way that intersection lines and/or intersection surfaces form, which extend into the depth of the through-opening.
