Slass syringes, the pistons of which are uniform over the entire length is strong and rests on the cylinder along its entire length,

also have the disadvantage that when the drug is drawn into the syringe, the user's fingers easily come into contact with the plunger. Badurah, the k-piston becomes unsterile. When indexing, this unsterile area of the olbena comes to the cylinder, infects it and the thin layer of medicament which is always between the cylinder and the piston, if the thin layer is in direct contact with the medicament in the rim of the cylinder, infection then easily occurs also with this liquid, especially with slow and therefore longer lasting injections of certain drugs » ¹¹

The invention also shows a 'syringe which eliminates all these deficiencies and which is particularly easy to. must be cleaned and kept sterile It is characterized by an angle-free cylinder *, preferably in Kropf or Bomhenfarm, which merges smoothly on its front band into a conical seat for the injection needle equipped with an enSspreeheiiaen (regenkonas) a piston, which is adapted in its shape to the shape of the cylinder end and provided with a stepped shaft r ^ er in the front end expands conically close to the outside to accommodate the conical insert of the injection needle or sleeve are equipped to be placed on the syringe, so you can use an intermediate piece according to the invention end, which in the cone »

The closure of the cylinder and the guide of the sorbent rod is also particularly two-fold. Kind of a BajjoasttversGlosses is put on. The backward hand of the cylinder can to. For this purpose, be equipped with an adjustment ring or the like. The design is particularly useful when the cylinder forms an outwardly reaching edge, collar or the like, which is flattened on opposite sides or at least on one side * The tfiarlssforai this Sand according to sand, a kagpenfSri & iger Deekel is used to guide the piston rod, which is also equipped with one or more suitable drainage points, with recesses being provided in the flattened ropes of the bevel and, by turning the Ueekel and cylinder against each other, the cylinder rim generally has recesses The lid is pressed with ice, so that the lid and cylinder are sufficiently tightly connected to each other * A syringe of the invention, like the Solgen, axis Slas, can be ordered from any suitable plastic, or a metal made of metal or similar can also be used * The inventive idea leaves the versehieaenstea.

Pie syringe "ordered essentially borrowed from a cylinder 1, which is essentially the 3? form of a mom.be or a drop has, -The Tordere -End 2 of the cylinder is slightly thickened and forms in its interior a sanded-in seat 2 for the cone 4 of an injection needle 5. ^ he Sits 3 ujid der! Conus 4 are precisely matched to one another, the needle 5 is light can be used in cylinder 1.

In the interior of the cylinder 1, a piston 6 is guided, the piston rod 7 is pushed through the lid 8 and provided with a handle 9, the lid 8 can be in any Way placed on the upper end of the cylinder interchangeably so that the opportunity is given to him at any time remove and pull the piston 6 out of the cylinder 1.

The cylinder 1 is preferably made of Gias or another suitable transparent plastic »2r has its outside one according to the teardrop shape of the Cylinder 1 uneven scale Io, which is marked with a

With the arrangement according to fig. 2, normal infection needles 15 are used with the syringe. your rear loads. % ine. Carry sap 14 to put on the syringe. Because such needles 15 could not be inserted in the seat 5 of the cylinder 1, an intermediate piece 15 is used here, which on the one hand is inserted into the seat 3 of the syringe 1 by means of the cone 16 and which has a conical projection 17 at its other end forms, on which the injection needle 15 sit iiirer cap 14 can be placed.

Guide the piston S with its piston rod 7 zvl and close the cylinder 1 backwards, using various deodorants. -which is equipped with side pins 19. The Beekel 2o has the bayonet socket 21 in its side collar, so that it can be branched with this over the plugs 19 and tightened by means of barking _teSOT " ^: 'i, Bel; 4ffl?:. 4 ^. 5-9, however, the cylinder 1 at its upper sin a desolate after ausaen bent covenant sand 22 · If the cylinder © las is made _r can thus look very produce this band 22 in the manufacturing Mont * Bieser sand 22 is two opposite sides 25 flattened. The bevel 24, which in its center forms the passage 25 for the piston rod 7, is in its alignment with the collar

with the flats 23 precisely adapted so that it can be easily pushed onto the cylinder 1 from above. In the flattened wall parts 26 of the cover (FIG. 6), slots 27 are provided which correspond in their text to the thickness of the band 22. If necessary, the slots 27 can also narrow in a wedge-shaped manner, and the thickness of the band can also grow in a wedge-shaped manner. If you put the cover 24 over the band 22 here, it is necessary beforehand to bring the flattened areas 23 with the wall parts 26 of the cover 24 into congruence. When attached, the position of the ropes is given in accordance with «8. If the cover is now rotated with respect to the cylinder 1, it can be achieved that the non-flattened ropes of the tape ~ '22 pass through the recesses 27 in the cover 24, as shown in FIG. 3 # 9. In this position there are covers and cylinder respectively. Syringes secured against each other »The wedge-shaped design of the band 22 and cover slots 27 enables the parts to be clamped well against each other» so that unintentional I * Ssen is prevented.,

The advantage of the new type of syringe is that it can be dismantled in a few simple steps and that its ropes have no angles or other areas that are difficult to clean. You can easily clean both the inside of the cylinder 1 and the seat 3 with a brush.The piston 6 is the same, & © x * with the piston rod 7 can consist of one piece (metal, ceramic, glass or the like .)
