Definitions

  • the invention relates to a syringe, in particular for medical use, with a cylinder which has an outlet opening at one end, namely the front end, and in which a piston is movable, the piston rod of which protrudes from the other end end of the cylinder and a handle comprises, at the or in the outlet opening a needle, in particular injection needle, or the like. Suction and / or administration part can be used or used in a fluid-tight manner.
  • Such syringes are generally known from medical technology. In view of the increasing risk of AIDS infection through multiple use of injection syringes, but also the transmission of other infectious diseases, it is known and customary to determine syringes only for single use. However, since syringes usually continue to function after a single use, it has been shown that multiple use of syringes or the continued use of used and separated syringes by unauthorized third parties cannot be reliably prevented. Syringes have therefore been proposed which can be rendered inoperable by the rotary movement of the piston or the piston rod by interrupting the connection between the piston and the piston rod. Such syringes are relatively complex to manufacture and therefore relatively expensive. For this reason, such syringes are also out of the question for developing countries.
  • DE 29 09 002 also describes a disposable syringe for medical use, in which the inner wall of the cylinder has at least one circumferential groove, into which at least one plunger part which pushes radially outwards snaps into place after the injection has been completed, so that it is no longer retractable ,
  • the inner wall of the cylinder has at least one circumferential groove, into which at least one plunger part which pushes radially outwards snaps into place after the injection has been completed, so that it is no longer retractable .
  • it is absolutely necessary to push the plunger to the foremost position. Only then will the aforementioned piston part snap into the groove. With skillful handling, multiple use of this syringe is easily possible. It is only necessary to ensure that the piston is not pushed into its foremost end position.
  • DE 38 28 127 proposes an injection syringe in which locking means are assigned to the piston and the piston rod, so that a maximum syringe volume can only be administered once. After an injection movement has been carried out, the piston is either blocked for another stroke-suction movement or irreversibly disengaged from the piston rod. Multiple use of this hypodermic syringe is therefore excluded.
  • the disadvantage of this syringe design is that a relatively large number of components have to be used to implement the locking function mentioned, so that production is complex and correspondingly expensive.
  • the present invention has for its object a
  • the essence of the present invention thus lies in the fact that the piston rod has a telescopic section which is made in one piece on the manufacturing side and which interacts with a locking means arranged inside the cylinder in such a way that the piston only has a single one, regardless of the (partial) volume which has been drawn up Sometimes it can be shifted either step by step or completely in the direction of injection, the one-piece design of the telescopic section being destroyed by the assembly of the piston rod and piston within the syringe barrel.
  • the telescopic function is activated by the assembly. This ensures, on the one hand, that the syringe is ready for drawing up the fluid to be administered after assembly.
  • the telescopic section is preferably to be handled or broken through a predetermined breaking point with a connecting section formed between the handle and the telescopic section cut connected.
  • This predetermined breaking point usually in the form of a material weakening - breaks when trying to overcome the blockage of a renewed stroke-suction movement by means of the locking means mentioned within the cylinder.
  • the telescopic section includes one
  • the telescopic section thus leads to a kind of "functional destruction of the syringe after a single use", whereby the function of the syringe cannot be restored even when using force.
  • the predetermined breaking point between the telescopic section on the one hand and the handle on the other then becomes effective This predetermined breaking point is designed so that it is located in the syringe barrel in every relative position of the piston rod. This is to avoid manipulation from the outside.
  • the locking means mentioned is also designed so that it allows movement of the piston rod in the direction of injection, but not one
  • the locking means is arranged within the syringe barrel in such a way that a locking element arranged on the plunger rod, in particular on the telescopic section thereof, is moved over the locking means when a volume or only a partial volume is injected If the stroke-suction movement is repeated, it is blocked by the abutment of the locking element mentioned on the locking means, in such a way that when force is used, the handle tears off the telescopic section.
  • the predetermined breaking point between the handle and the telescopic section is located directly on or at least in the immediate vicinity of the side of the latching element facing the handle.
  • the handle and / or the piston are formed in one piece with it.
  • This embodiment is particularly simple in terms of production technology and in particular assembly technology and is accordingly preferred.
  • the syringe consists essentially of Chen only from two parts, namely syringe cylinder with injection needle on the one hand and piston assembly on the other.
  • the telescopic section preferably comprises two sections which can be telescoped with one another and which are connected to one another in one piece on the production side, preferably via a predetermined breaking point, in particular film-like connecting elements.
  • This predetermined breaking point between the two sections of the telescopic section is designed such that it breaks when the telescopic section is placed inside the syringe barrel when the piston associated with the telescopic section and first inserted into the barrel during assembly is in contact with the front end or bottom of the syringe barrel comes.
  • the position of the syringe is then " also in a position in which it is ready for the single drawing up of the syringe volume.
  • the telescopic section has a locking element, in particular in the form of a locking disc, which corresponds to the locking means arranged inside the cylinder, in particular in the form of an annular projection, in such a way that the locking element can be moved past the locking means in the injection direction, in the opposite direction is blocked by the blocking means.
  • the telescopic section comprises a rod-like section on the one hand and a sleeve-like section on the other, the sleeve-like section being defined by at least two sleeve shells.
  • the piston can either be connected to the rod-like section or, conversely, to the sleeve-like section stand.
  • the aforementioned subsections are then connected in the opposite manner to the handle, preferably via a connecting section extending within the syringe barrel.
  • the locking means formed within the cylinder is designed as a wedge-shaped projection, in particular an annular projection, the surface of which facing the handle extends in a wedge-shaped manner inwards in the direction of injection, while the surface facing the piston lies approximately perpendicular to the cylinder axis. This area then forms the barrier area against the syringe being pulled open again.
  • a further movement stop for example likewise in the form of an annular projection, is preferably formed within the cylinder, which limits the maximum movement of the piston in the suction-stroke direction and thus the maximum drawing volume.
  • this movement stop is located in the upper end region of the cylinder and interacts with the locking element assigned to the telescopic section.
  • the movement stop mentioned can be designed similarly to the locking means, i.e. as a wedge-shaped ring projection. However, it is also conceivable to design this movement stop as an annular bead. It is also conceivable that at least one wedge-shaped nose projection serves as the movement stop. The same also applies to the blocking means mentioned above. Preferably, however, three wedge noses distributed evenly over the circumference are provided in order to ensure absolute functional reliability.
  • the inside diameter of the front piston movement section of the cylinder is preferably somewhat smaller, in particular about 1 / 10-3 / 10 mm smaller than the inside diameter of the rest of the Handle facing section of the cylinder.
  • the piston can be formed in one piece with a piston rod and handle. These parts are usually made of polyethylene (PE). It is also conceivable to produce the piston separately from a rubber-like or polyethylene-based material. It must then be fastened separately to the piston rod.

  • a locking tab in the handle, in particular a locking tab which extends parallel to the longitudinal axis of the cylinder and which extends between the handle and the upper end or edge of the cylinder and only allows movement of the handle in the direction of injection after removal.
