Description

The utility model relates to the field of medicine, namely to devices for staining biological preparations (blood smears) on glass slides.

The clinical diagnostic laboratories of medical institutions and research institutes make extensive use of the preparation of microscopic preparations for research by taking biological samples from a patient, applying smears to slides, followed by preliminary processing, fixing and staining with special technological fluids. Staining of drugs makes it possible to identify various structural elements of the bioassay, to effectively conduct microscopic studies and diagnosis. The smears are painted in both mechanical and automatic devices.

Known automatic device for staining samples (US patent No. 5573727, 1996), which includes an indoor enclosure containing many bathtubs, drawers for input and output, a movable carrier tripods in the form of a transport mechanism for controlling the movement of sliders from bath to bath between the original and end positions and microprocessor control system.

Also known is a machine for painting smears on slides (patent RU No. 2440562, IPC G01N 1/30, 06/10/2011) containing a sealed working chamber, tripod, bathtubs, pallets, a working table on which stations with bath positioning devices are located, pallets, a movable tripod carrier equipped with a gripper, a lifting mechanism and a control and monitoring unit (Prototype).

However, in the known devices, tripods with glass slides (holders) are made movable and are moved by process steps using movable tripod carriers, which are an arrow with step drives and grippers.

In this case, the automatic execution of the program by the mobile carrier of the tripods includes a large number of operations, which can cause structural elements of the mechanisms to break down.

In the inventive utility model, the bathtubs are movable, with the possibility of vertical and horizontal movement using the mechanism transmitting movement to them. Using the mechanism for moving the baths allows you to abandon complex gripping devices and additional control units, which leads to increased reliability of the device.

The utility model is aimed at creating a device of simplified design, reliable in operation and convenient in operation.

The technical result is achieved by the fact that in a device for automatically painting smears on glass slides, including a housing with a base and a lid, containing a block of baths with reagents for staining smears, a glass slide holder mounted to move along the cover, a loading and unloading glass holder, drying and control units, the bath unit is movable and installed in the bath holder with the possibility of horizontal and vertical movement from the loading cell to the unloading cell glass holder between the initial and final position of the specified time cycles, using the unit for mechanical movement of the baths containing an engine with an eccentric, vertical and horizontal guides with carriages and templates for vertical and horizontal movement of the baths, while the horizontal movement guide is installed on the base of the device, the vertical guide the movement of the bathtubs is fixed on the carriage of the guide horizontal movement of the bathtubs, and the holder of the bathtubs is fixed flax on the carriage of the vertical movement guide, in addition, the eccentric is kinematically connected to the templates, one of which is mounted on the vertical guide, and the other is connected to the base of the housing.

The utility model is illustrated by drawings:

in FIG. 1 - shows a device for automatic painting of smears, top view;

in FIG. 2 is a section AA in FIG. one;

in FIG. 3 is a general view of the mechanical displacement unit with the position of the baths at the top;

in FIG. 4 is a general view of a mechanical displacement unit with the position of the baths below.

A device for automatically painting smears on slides includes a housing 1 with a base 2 and a lid 3, containing a block of trays 4 with reagents for staining smears, a slide holder 5 mounted with the possibility of movement along the lid 3 of the housing 1, cells 6, 7 of loading and unloading the holder 5 glasses, blocks 8, 9 of preliminary and final drying and control unit 10.

The unit tray 4 is movable, installed in the holder 11 baths with the possibility of vertical and horizontal movement. The bathtubs are filled with reagent and flushing fluid. To the left, from the first reagent bath, is located the load cell 6 of the prepared glass holders 5. To the right of the last bath with the washing liquid is the block 9 for the final drying of the samples and the cell 7 for unloading.

The movement of the baths 4 and the glass holder 5, between the initial and final position of the specified time cycles, from the loading cell 6 to the glass unloading cell 7 is controlled by the mechanical movement unit 12.

The mechanical movement unit 12 of the baths comprises an engine with an eccentric 13, vertical and horizontal guides 14, 15 with carriages 16, 17, vertical and horizontal templates 18, 19. The mechanical movement unit 12 is controlled by the control unit 10, which determines the time cycle of movement of the baths. At the end of a given time cycle, the bath unit 4 carries out the next cycle.

The guide 15 with the carriage 17 horizontal movement of the baths 4 is installed on the basis of the housing 1 of the device.

The guide 14 with the carriage 16 of the vertical movement of the baths 4 is mounted on the carriage 17 of the guide 15 of the horizontal movement.

The holder 5 baths mounted on the carriage 16 of the guide 14 vertical movement.

The template 18 is mounted on the vertical guide 14. The template 19 is connected to the base 2 of the housing 1.

The eccentric 13 is kinematically connected with the templates 18, 19. When the eccentric 13 rotates, its roller moves along the vertical and horizontal templates 18, 19 for the movement of the baths 4.

To exclude staining and conducting studies on undried smears, the samples are subjected to preliminary and final drying. Preliminary and final drying is carried out by a stream of warm air from the fans.

The control unit 10 is designed to control the device and to supply electricity to the unit 12 of the mechanical movement of the baths 4.

The process of staining smears occurs by a linear method.

To prevent the negative effect of vapors of reagents on the human body, the operation of the device is carried out in a fume hood.

The device operates as follows.

The unit 4 baths with reagents and washing liquid is installed in the holder 11 baths. Power is supplied, the time relay turns on, and when a specified time cycle is reached, the engine turns on. The engine transmits the rotation to the eccentric 13, the roller of which, moving along the templates 18, 19 drives the block 4 of the bathtubs.

Block 4 baths from the starting position moves down - left - up to the cell 6 loading holder 5 glasses. The glass holder 5 is loaded into the first tray of the block and moves together with the block 4 to the right. Then, the tray unit 4 again moves down - left - up to the loading cell 6 and the next glass holder 5 is already loaded into the first tray, and the first holder 5 is loaded into the second tray of the unit 4.

Then the cycle of movement of the bath block is repeated. Upon subsequent movements, a new glass holder 5 is loaded into the first tray of block 4. In the second and third bath, the previous ones are loaded. After painting and washing, the glass holder 5 is automatically moved to the final drying unit 9, and then to the discharge cell 7. At the end of the specified time cycle, the block 4 of the movable baths carries out the next cycle.
