Definitions

  • the invention relates to a holding device for tubular vessels, preferably for reaction or sample vessels for the pretreatment of biological test material, in particular according to the radio-immuno-assay (RIA) technique, with two spaced-apart through openings for a large number of vessels having plates and with in the region of the passage openings, each vessel individually assigned, resiliently designed holding elements.
  • RIA radio-immuno-assay
  • Such holding devices are known from US-A-2 917 183 and US-A-3 390 783.
  • the holding elements are punched out of the material of the upper holding plate having through openings and bent downward.
  • the tubular vessels stand on a third plate, namely the bottom of the device.
  • a similar type of holding device is known from US-A-3 142 385.
  • a holding device which is common to a number of vessels and acts on each vessel between the plates, is arranged. It consists of two wires arranged parallel to each other, the spacing of which is slightly less than the diameter of the vessels.
  • the vessels stand on a third plate, namely the bottom of the device.
  • each individual vessel must also be removed from the holder again by hand if the vessels are to be transferred, for example, into the cassettes of a measuring device.
  • a holding device for tubular vessels is known, by which the object is achieved that the passage openings of the holding plates can be adapted to the different sizes or diameters of the vessels.
  • the device is composed of an S-shaped base body and a C-shaped slide which can be adjusted by hand in sliding guides of the base body in such a way that the clear width of the passage openings can be changed.
  • This construction makes it necessary that both the base body and the slide must be formed with two openings for each vessel.
  • the holding diameter of the passage openings is determined by the vessel which has the largest diameter. In this device, too, the vessels stand on the base plate of the S-shaped base body, at least it stands below most of the through-openings of the apparatus for free passage of the vessels downwards.
  • the invention is based on this prior art, the task of improving a bracket of the type described in such a way that all the individual and fixed stored vessels easily and quickly, d. H. can be transferred into containers at the same time as they are used for carrying out the respective operation.
  • the solution of the problem set by the invention is that the holding element is designed as a leaf spring mounted between the plates and all leaf springs can be locked and unlocked together by means of a control rail.
  • the main advantage of the holding device according to the invention is that all sample vessels of the holding device, which are simply placed on the cassettes of a radiation measuring device, can be released into the cassettes of the measuring device by unlocking them.
  • the holding device permits a grouping of sample vessels combined into units, as a result of which the largest possible number, approximately 50 to 100, of sample vessels can be transferred from one operation to the other up to sample counting in a handy manner at the same time.
  • the samples are inserted into the multipurpose holder according to the invention, in which the positioning of the holding elements of each tubular vessel is designed so that the position of the samples corresponds to the position of the carrier of a block of assembled cassettes of a radiation measuring device. Since the sample cups are used with leaf springs that are already locked, a firm clamping of the sample cups is guaranteed right from the start, and that in the full range of manufacturing tolerances.
  • the holding device according to the invention is a multi-purpose holder in that all sample pretreatment work can be carried out in this multi-purpose holder.
  • a particular advantage of the holding device according to the invention is that a connection element between the sample pretreatment and the sample counting is available for the more flexibly usable radiation measuring devices with sample carrier, which enables partially automated work. Each work step is carried out for all samples at exactly the same time under exactly the same conditions. The transfer of all sample vessels into the radiation measuring device requires only a few simple steps. A marking of each individual sample tube can because of the unchanged positioning in the holding device according to the invention.
  • the holding device according to the invention thus allows a greater quality of work in laboratory work with less work, since it proves to be a multi-purpose holder.
  • each leaf spring is individually and resiliently designed, the tolerances that are permissible in the manufacture of the vessels can be safely compensated for.
  • Another advantage of the design of the holding elements as a leaf spring is that the tubular vessels are absolutely vertical and can be clamped, in particular if the passage openings of the plates in their area opposite the leaf spring have two straight lines which are preferably arranged at right angles to one another.
  • the control element for jointly locking and unlocking the individually designed leaf springs is designed in an advantageous embodiment of the invention in such a way that, on the one hand, the leaf springs arranged next to one another are held in a slot in each case of a shaft and the shafts arranged one behind the other at their ends in two vertical, the upper and lower plate spaced strips are rotatably mounted and that each shaft has an obliquely downward connecting pin which engages in a common to all shafts, displaceable between an unlocking and a locking position control rail for the leaf springs. It is therefore only necessary to actuate this control rail in order to clamp all the vessels which can be inserted into the holding device.
  • the common unlocking of all vessels which enables their easy transfer into the radiation measuring device, is realized according to the invention in such a way that the holding device has two carrying handles arranged perpendicular to the upper plate, one of which is mounted on the locking bar and can be tilted about a horizontal axis carries the two locking levers.
  • the tiltably mounted handle can be equipped with an appropriate safety device.
  • the dimensions of the holding device are of course chosen so that it is suitable for inclusion in a centrifuge, a vibrator or rotator or in an incubation bath.
  • baseboards are attached to the underside of the lower plate on the two narrow sides of the holding device. These and the two baseboards arranged between them are each designed so that the required hold is guaranteed if the holding device is placed, for example, on a block of assembled cassettes of a radiation measuring device in order to transfer all vessels into the radiation measuring device by means of a simple handle .
  • the holding device according to the invention is that the inlet and outlet openings of the two plates are selected so that they are used to hold vessels of different diameters, e.g. B. 8 to 12 mm, are suitable. It goes without saying that the vessels can be arranged by means of the holding device according to the invention in such a way that the positioning of the samples in the holding device according to the invention corresponds to the required positioning of the carriers of a block of assembled cassettes of the radiation measuring device.
  • the vessels are inserted into the holding device according to the invention after the holding device has been brought into its locking position.
  • the holding device consists of two plates 1, 2 held at a distance from one another (cf. e.g. 1 and 4).
  • the upper plate 1 has inlet openings 3 and the lower plate 2 has inlet openings 4 (FIG. 8) for a multiplicity of vessels 5.
  • a common, on each vessel 5 engaging, unlockable holding device is arranged, the construction of which will be explained below.
  • the inlet and outlet openings 3, 4 have a teardrop shape.
  • the drop attachment is formed from two straight lines 6, preferably arranged at right angles to one another (FIG. 7).
  • the holding device has a leaf spring 8 as a holding element for each vessel 5 (FIGS. 1 to 3, 7 and 11 and 12).
  • the leaf springs 8 arranged side by side are each held in a slot in a shaft 9.
  • the shafts 9 arranged one behind the other are rotatably supported at their ends in two vertical strips which keep the upper and lower plates at a distance, of which the strip 10 can be seen in FIG.
  • Each shaft 9 has an obliquely downward-pointing connecting pin 11 which engages in a control rail 12 for the leaf springs 8 which is common to all shafts 9 and which can be displaced perpendicularly to them between an unlocking and a locking position (FIGS. 11 and 12).
  • the control rail 12 engages with one end on a locking bar 13 arranged perpendicular to it (FIG. 1).
  • the locking bar 13 is under the action of a compression spring 14 which is guided in a tube 15 fastened on the upper side of the lower plate 2.
  • the locking bar 13 has at each of its two ends a pivotably mounted locking lever 16, which can be locked by overcoming spring pressure on one of the locking plates 17 fastened to the lower plate 2, as shown in detail in FIGS. 9 and 10.
  • the holding device has two carrying handles 18, 19 arranged perpendicular to the upper plate 1 (FIGS. 5, 6).
  • the carrying handle 19 is mounted on the locking bar 21 such that it can be tilted about a horizontal axis 20.
  • the carrying handle 19 carries the two locking levers 22, 23. This embodiment has the advantage that the carrying handle 19 actuates the locking levers 22, 23 at the same time.
  • the locking bar 13 is independent of the carrying handles. Only the other carrying handle 24 can be seen from the drawings. This embodiment has the advantage that the locking cannot be unintentionally released by grasping the carrying handles.
  • the carrying device is also provided with baseboards 25, 26.
  • additional baseboards can be provided in between.
