Diagnostic device for laboratories

The innovation relates to a diagnostic device for laboratories for the continuous movement of reagents in test tubes, consisting of a drive device controlled by a time rotatable, inclined disc on which the test tubes can be attached.

Such diagnostic devices are already known in which each device is equipped with a disk for the test tubes. By switching on the rotary drive, the test tubes are ^{moved in a circular motion during the preset 4} · Uten time, so that the reagent is kept in constant motion and thus mixed as a result of the inclined position of the disk. A certain number of test tubes can be attached to each disk. Additional test tubes must therefore either be handled on a different diagnostic device or set aside until the movement cycle of the existing device has expired. A correspondingly large number of diagnostic devices must therefore be provided for rapid evaluation. In many cases, however, this is not possible, for example for reasons of space and / or costs, since the amount of reagents to be examined is often very different. In this way, the devices are only used more or less often, so that an uneconomical use of these devices arises.

The task of the innovation is therefore to improve the diagnostic device in terms of improved utilization.

This object is achieved by the innovation characterized in that the disc r- with a plug means for the rotationally fixed, axialan encryption bind is equipped with other wheels.

An expedient training results in a further embodiment of the innovation in that the plug-in device consists of at least consists of a head protruding from the top in the axial direction of the disk, which is inserted into a recess on the underside, is preferably used with frictional engagement.

A particularly simple training is characterized by another feature of the innovation in that the central A head is provided on the top and a recess is provided on the bottom.

The advantages achieved with the innovation are, in particular, that the plug-in device axially enables several discs can be plugged together. In this way, the test tubes of several disks are made with a drive device moved at the same time. As a result, the number of devices can be reduced or the number of panes to be kept moving can be increased will. The space required for the diagnostic device is thus used better than before. By training the Plug-in device with frictionally connectable parts connecting and disconnecting the disks is easy and problem-free, so that the putting on and taking off or exchanging can be done quickly and almost without loss of time. With the diagnostic device after the innovation can therefore be treated a large number of reagents, so that per device and thus per Job a high utilization is achieved.

Embodiments of the innovation are shown in the drawing and are described in more detail below. Show it:

1 and 2, the diagnostic device for laboratories for the continuous movement of reagents in test tubes consists of a housing 1 with a rearwardly inclined front wall 1 '. In this housing 1 a motor drive device, not shown in detail, is provided, z.3. with an electric motor which can be connected to a power source by a cable 2. A switch 3> arranged in the front wall 1 'is used for manual switching on and off, while the switch-on duration can also be preselected by a timer k. Through the

The drive shaft 5 of the drive device protrudes from the front wall 1 ′, the end of which carries a drive pulley 6. A disk 7 is arranged on this drive disk 6, onto which a further disk 7 ¹ is placed, which in turn carries another disk 7 "and so on." It can be seen that on the drive shaft

5 axially several discs 7 can be arranged, which turn with the drive shaft 5.

According to FIG. 3 7, the disc of a disc-shaped upper part 8 and just such a bottom part 9 ₅ which are connected to each other. Appropriately, these parts 8 and 9 are made of plastic. The upper part 8 has an upwardly projecting cylindrical head 10 in the middle. Radially on the outside of this head 10 approximately semi-cylindrical inserts 11 are formed in the upper part 8, which are adapted to the shape of the test tubes so that these test tubes 12 can be pressed into the inserts 11, preferably with frictional engagement. The underside of the upper part 8 is covered by the base part 9, this being in contact with the inserts 11 at the bottom and being connected to them there, for example being welded. In the middle, i.e. below the head 10, the bottom part 9 has a recess 13, namely according to FIG. 3 in the form of a pot-like deformation protruding upwards into the upper part 8, while the radially outer ring part IZf is flat. Head 10 and recess 13 are matched to one another in cross-sectional shape and diameter, namely the outer diameter of head 10 corresponds approximately to the inner diameter of recess 13 so that a disk 7 can be inserted with its head 10 into recess 13 of another disk 7 . Both disks 7 are held together by frictional engagement and set in rotation by the drive shaft 5. The head 10 and recess 13 thus form a plug-in device 10, 13

The disk 7 according to Fig. I ^ is constructed in principle as has just been described. The same parts have therefore been given the same reference numerals. Instead of the one central head, however, several heads 10, which are radially offset from the center, are provided on the upper part 8 on the flat center part. Associated with these heads 10 'are recesses 13''which are provided in the bottom part 9, which is designed as a flat disk, and which are designed as a hole with a diameter matched to the head 10'. Here, too, several disks 7 can be detachably, but non-rotatably connected to one another by the ^{plug-in device 10 ', 13f} consisting of the heads 10' and the recesses 13 ', as indicated by dash-dotted lines.

The disk 7 according to FIG. 5 consists of a single, molded plastic upper part 8 '. The plug-in device is composed here of an outer cylinder surface 10 "provided in the upper area of the outer circumference of the disc 7 and an inner cylindrical surface 13" arranged in the lower axial area of the inner circumference , the diameters of which are adapted to one another so that the inner cylindrical surface 13 "of a disc 7 can be pushed axially onto the outer cylinder surface 10 ″ of another disk 7 with frictional engagement. In this way, several such disks 7 can be arranged one above the other so that they are set in rotation together by the drive device.

Of course, other designs of the disk 7 and the plug-in device 10, 13 are also conceivable, around a plurality of disks 7 at the same time to be coupled to the drive device. The drive shaft 5 of the drive device could also be a profiled shaft be formed, on which the discs 7 are pushed with a correspondingly profiled, central opening, so that they are held axially by the drive shaft 5 and driven by positive locking. The housing 1 expediently consists of a hood made of plastic, the color of which is matched to the panes 7.
