Preliminary prepared nutrient medium carrier for quantitative and qualitative estimation of microorg

专利摘要:
The present invention provides a prepared nutrient substrate carrier for the qualitative and quantitative determination of micro-organisms, comprising an object carrier coated with at least one nutrient substrate, which object carrier is firmly attached to a lid and, during storage and during incubation, is present in a transparent vessel which can be securely closed with a lid, wherein the coated object carrier is enclosed in an envelope during storage, said envelope being adapted to be easily removed before inoculation.

专利说明:

The invention relates to microbiology, namely to previously prepared nutrient medium carriers for the quantitative and qualitative determination of microorganisms, mainly pathogens.
The purpose of the invention is to increase the shelf life of the nutrient medium.
Figure 1 shows a previously prepared carrier of the nutrient medium, a longitudinal section; Figures 2 to 11 show carrier embodiments for several different media, cross sections; Fig. 12 shows a variant of carrier implementation, the shell of which is connected to the lid of the container by means of a snap lock.
The carrier contains a container 1 with a lid 2, a substrate 3 for nutrient medium 4 installed inside the tank 1 and rigidly connected to the cap 2, a removable waterproof sheath 5 installed in the tank 1 and connected to the substrate 3, an elastic seal 6 installed between the shell 5 and 2
At the bottom of the container 1, a projection 7 is made, by means of which the shell 5 is pressed against the seal 6.
The shell 5 is made of a polymer film in the form of a sleeve placed between the cap 2 and the bottom of the tank 1
The operation with the device is carried out as follows.
One or more nutrient media 4 are deposited onto the substrate 3, depending on the embodiment of the carrier.
Figure 2 shows a nutrient medium in which four different types of nutrient media can be inserted. Shell in this case
is rigid and round and, as the storage medium is 45, the substrate shown in FIG. 1 can, by means of, be provided with a removable waterproof
1. Pre-prepared nutrient medium for quantitative and qualitative determination of microorganisms, containing a crush container, inside of which a substrate for the nutrient medium is vertically mounted, rigidly connected to the lid, characterized in that
the protrusion on the bottom is pressed against the seal krsh1ki. The substrate 3 is made with a cross-shaped cross-section.
FIG. 3 shows a carrier on which two types of different nutrient media are applied. The shell, in this case, is rectangular, rigid and can be pressed by a protrusion and bottom to the seal on the screw cap.
Figures 4 and 5 show a carrier on which they can be placed before various types of nutrient
n The round or square shell is tight and can be made by casting. Media carrier can
performed with three; .pty and more plates or taps. The shell 5 can be made in a cross section of a circle, triangular, pentagonal, polygonal and rectangular (Figures 6-11). The substrate 3 can be made of three rectangular plates connected by large sides and arranged at equal angles to one another.
After applying the nutrient medium 4, a waterproof sheath 5 is put on the substrate 3 to ensure the necessary pressure tightness to the cover 2, which is preferably achieved
using a latching slide (not shown) and a protrusion 7 at the bottom of the container or by gluing. The casing 5 is generally in the form of a rigid sleeve or sleeve. The substrate 3 with the nutrient medium 4 and the shell 5, previously connected to the lid 2, is immersed in the container 1, the bolt 2 is screwed. The volume of gas between the inner walls of the tank
1 and the shell serves as thermal insulation and prevents the formation of condensate on the inner walls of the shell 5.
