Description

The requirements for consumables, as well as, if possible, for inexpensive equipment, devices that go deep into the organs of a person, should, if possible, ensure their one-time use or, at least, should have removable disposable nozzles, or a high degree of sterilization if it is impossible to provide - single use.

The objective of the claimed utility model is to increase the non-invasiveness, patient safety, convenience, technical service while simplifying the dental research complex.

The essence of the claimed utility model is that as part of a dental research complex containing a computer, a microscope and an optical digitizing device installed with the ability to fix and combine the lens of the latter with the eyepieces of the microscope and transfer the processed image to a computer, there is a device for collecting liquid biological material, representing a dental tweezers of two branches, each of which is made with a continuation in the form of shortened necks with transverse dimensions frames smaller than the transverse dimensions of the branches and turned at an angle and having gripping jaws on the working ends in the form of rounded, converging surfaces on the outer sides touching the gums, and a flexible strip for collecting gingival fluid from highly hygroscopic foam with a developed absorbent surface with sizes commensurate with the dimensions of the investigated cavity.

A dental complex with the foregoing features is also claimed, the rotation angle of which is 100 ° -145 °.

In addition, a dental research complex with the above features, in the device for collecting biological fluids which flexible absorbent strip for collecting gingival fluid is limited in size: length 7-10 mm, width 1.8-2.2 mm, thickness 0.8-1, 5 mm.

In addition, the claimed dental research complex with the above features, containing a set of strips for the possibility of replacement.

The technical result of the claimed complex is illustrated by its differences. The distinctive node of the complex has devices for taking biological

the material is the geometry, tweezers configuration, and the material of the flexible absorbent strip, as well as its dimensions for collecting the gingival fluid, which were selected and worked out by the authors experimentally, in accordance with the anatomical features of the places of sampling of the liquid biological material. The inventive geometry of the tweezers allows you to resolve a serious contradiction. So, if the tweezers provide high characteristics as an exciting and holding means, then it interferes with the view, closing the view of the visible field. With its claimed design, the working holding part remains on the side of the field of view, thereby achieving the effect of visualization and control of the doctor’s actions. The ability to vary the size of the strips along the length, width and thickness of the foam allows you to choose the most optimal size for both a child and an adult, taking into account the dimensions and anatomy of the patient's cavities, including the tooth. The claimed dimensions of the foam strip for sampling gingival fluid: length 7-10 mm; width 1.8-2.2 mm; a thickness of 0.8-1.5 mm prevents it from getting stuck in the immersed space, as well as stretching the gingival pocket itself from the excessively large size of the strip. The use of digital technology accelerates the process of researching biological fluids and allows you to track the research process in dynamics, without requiring special qualifications from the user.

The inventive dental research complex is illustrated using figure 1 - scheme of the dental complex, figure 2 - a device for collecting gingival fluid in statics, 3 - the dynamics of the claimed complex. Positions 1-10 in figure 1-3 indicated:

1 - branches of tweezers;

2 - gripping jaw forceps;

3 - shortened jaw necks;

4 - bevel gripping jaws;

5 - angle of rotation;

6 - flexible absorbent strip;

7 - a glass slide;

8 - a microscope;

9 - optical digitizing device;

10 - computer.

In the claimed dental complex, the distinguishing nodes are tweezers of a special design with an absorption device in the form of a flexible strip of highly hygroscopic foam, which not only grips and holds the tweezers, but is able to place the target in the gingival pockets of the studied teeth under the supporting elements. The tweezers are two springy jaws 1 with gripping jaws 2 in the form of rounded plates at the working ends. The jaws of 1 tweezers are continued in the form of shortened necks of 3 gripping jaws with transverse dimensions smaller than the transverse dimensions of the jaws, taking into account their special purpose - work in the lateral sections of the dentition and visualization of this particular space. The flexible absorbent strip is made of foam rubber, which is widely used in medicine - polyurethane foam (GOST PPU-ES-6055 127-82), which has a developed absorbent surface. It is known that foam rubber has the properties of capillary vessels, in addition, it has hygroscopicity, elastic properties and the ability to restore shape, and also has open pores.

The tweezers of the claimed dental complex with shortened necks 3 branches, oriented with respect to the horizontal direction of the branches 1 at an angle from 100 ° to 145 °, allows not only to securely hold the flexible absorbent strip 6, simultaneously deflect the gingival margin and introduce the absorbent strip 6 into the gingival sulcus, but also allows you to work with a limited open mouth without overstretching of the soft tissues of the patient's face. After immersion in the gingival pocket, the absorbent strip 6 is held until all the pores are filled, i.e. until completely wetted. As a result of the effect of capillary vessels with open pores of foam, wetting with biological fluid quickly occurs. When touching the glass slide 7 after the intake of the biological fluid, the filled capillaries easily give portions of it to the glass slide 7 without effort and violating the integrity of the cellular material. A glass slide 7 with biological fluid is mounted on a microscope stage 8. To select a field of view, images are examined through the lenses of the microscope 8 with magnification. In the process of research by manipulating macro- and microscrews of the microscope, image clarity is achieved. Then capture the image of the test fluid

optical digitizing device 9. Then change the field of view of the image the required number of times for this study, each time repeating the procedure for fixing images. The resulting material is stored for subsequent comparison with samples from the library of computer standards 10.
