SU373296A1 - ADAPTATION FOR CUTTING AGAR PLATES - Google Patents

Description

The invention relates to the field of medical engineering, namely to adaptations for the cutting of agar plates.

A device for the cutting of agar plates is known, which contains a stationary body vertically, which is glass with a side process, equipped with upper and lower plugs, a punching device in the form of a thin-walled tube passing through the bottom tube over the diameter of the cut holes, and grooves with rubber hose mounted on the lateral process. A second tube of smaller diameter is inserted into the top plug, passing through the body into the inside of the first tube.

To automate cuttings in agar gel and improve the accuracy of measuring the growth zones of active biological substances, the proposed device is equipped with a cross slide support along a straight line and the body inside it is made movable with an optical projection system mounted into it, the center of which is aligned with the center of the stamping device, with an auxiliary channel measuring diaphragm, colored glass, potentiometer and scale.

FIG. 1 shows the proposed device, front view; in fig. 2 - the same view

Sat010.

The fixture is mounted on a stable bed 7. In the lower part 2, there are power supply elements and a roller of software control of a cross-slide 3 with a plate 4, prop-agan, and a stamping device 5. Above the cross-support 3 there is a body 6 having movement on the rails 7, in which the stamping device 5 and the optical projection system are mounted, consisting

from one lower light source 8 with a condenser 9, a plate 4, a double prism W, a lens //, a mirror with reverse reflection 12 and an inclined projection screen 13 with a vertical IK1al1NY1M viewing angle up.

An auxiliary beam channel is also inserted to illuminate the orifice plate .14.

Device for die-cutting agar plates works as follows. The cross-support 3 irvv-bt B moves along a rectangular line with even shafts and control elements, and during moving to intermediate downtime at the end of the course, the punching device 5 at the top cuts out the agar plate.

A plate is obtained having 64 holes arranged in a square. After the die cutting, the holes are filled with the solution to be analyzed and the plate 4 is laid in

incubator. After incubation, it is re-inserted into the mount of the cross slide 3. The body 6, located above the cross slide 3, is moved like this. that both centers coincide.

The movement is achieved by means of rollers on rails 7. In the "measuring" position, body 6 after disconnection and locking elements is set so that the center of the rays in the reference block coincides with the former center of the stamping device. After switching on the device, the corresponding switch to the position "diffusion measurement is watered with agar plastic 4" and on the crescent plate moves in the same way as during cutting. The auxiliary channel of the rays falls on the aclone plane of the double prism 10 and then it is set into the main channel of the rays. In this case, the distances between the object and the image and the aperture and the prism are the same. When B1 rotation measuring diaphragm M tan:

2-.

The generative dimensions of the image are transmitted through a temperature-compensated potentiometer as an analog of an electric magnitude to the self-identifying one.

Subject invention

Device for die-cutting agar blades containing body and stamping

. „A device, characterized in that, in order to automate the cutting and increase the accuracy of measurement of the growth zones of active biological substances, it is equipped with a cross-shaped support port for moving along straight lines when performed; 1 ;; The research institute of the case is movable with an optical projection system installed in it, the center of which is combined with the center of the punching device, an auxiliary channel with a measuring diaphragm, colored glass, 2 (1 tensiometer and reference scale).
