Description

B E S O H R E.:i B U N G

The innovation concerns a sample distribution device that at least an upwardly open sample holder for receiving the sample container has.

.; Numerous samples are closed every day in testing laboratories

investigate. Especially in the medical-chemical It is of vital importance that the samples are not confused before and during the examination will. It is obvious that in such cases

\. Mix-ups can lead to irreparable damage.

Today, a large number of sample holders, e.g. test tubes, each with a specific Sample of a specific patient contained, labeled and for chemical-technical examination in a test tube rack provided. Depending on the needs, a particular test tube is made with a pipette a sample is taken. To be on the safe side, it is necessary to remove the test tube from the test tube stand and to check its labeling.

Practice has shown, however, that there are too many Errors come. Above all, a mix-up or inaccurate identification of the labeling leads to removal and examining a wrong sample. Furthermore, it is extremely troublesome to find that among the numerous test tubes to search out and remove the desired. It also slows down the way you work. On top of that, through the necessary concentration in selecting and identifying certain samples quickly tires the staff, which

not only reduces the working speed further, but also increases the possibility of errors even more.

The function of the furnace is therefore a sample distribution device of the type mentioned, in which the possibility of making mistakes is significantly reduced or even turned off.

In the case of a sample distribution device of the type mentioned, this task is performed by a vertically movable, automatically controlled one The cylinder plunger underneath each sample container released.

The cylinder joint is automatically controlled electro-pneumatic. The address takes place via an input device as a peripheral device of the EDY. From the EDV Hechner signals are given via an interface to an electrical part of the sample distribution system, which is a corresponding pneumatic part activated, so that a certain cylinder, which is controlled by solenoid valves is, extends and thus lifts the desired sample container from its buoy position in the sample container. By this lifting the sample container containing the desired sample is lifted out of all the other sample containers, so that the desired sample can be taken and analyzed quickly and easily. In particular, however, there is a risk of confusion almost impossible.

According to a preferred embodiment, the sample holder is slidable on the worktop in a guide rail and adjusted in a position in which the cylinder plunger is assigned to the individual sample containers are. Through the guide rails on the worktop

a clear assignment of the cylinder tappets to the sample containers is facilitated, which increases the speed of the Sampling increased.

According to a further embodiment of the innovation are recesses are provided in the guide rail into which the specimen holder engages. This is particularly advantageous if several specimen holders are used and serves to speed up the clear assignment of the different ones Sample containers to their associated cylinder tappets.

According to a further embodiment, a coding magnet is permanently installed on the sample holder, which is locked in State of the specimen holder, the corresponding reed relay is activated. This also serves to ensure the clear assignment of the sample container to the associated cylinder tappet.

An embodiment of the claimed innovation is explained in more detail below with reference to the figures.

The cylinders (6) are worked into the worktop (5) of the sample distributor so that the cylinder plunger (4) with the damping element protrudes upwards through the worktop and when pressure is applied executes its constructively limited way to the top. The pressurization takes place via solenoid valves, which linked with pneumatic logic elements are chained in a matrix circuit.

f. These solenoid valves are located in the housing of the - ^ robenverteilge-

räts housed below the worktop (5). the electrical control of the solenoid valves takes place via an electrical connection in the form of a multiple plug

(8) and the interface, which in turn evaluates the IT pulses.

The construction of the cylinder (6) takes place in the easter dimension of the Sample holders (2) in units of 25 pieces each, which according to the modular principle of fifties, seventy-five, hundreds or more units can be joined together.
