The device according to A.1, about the t i l and th e with the fact that the elements for the separation of Hpf is made in the form of toothed perforators.

Description

The invention relates to medical technology, in particular to devices used in helminthological examinations.

It is known to use adhesive tape as a sampling device, a length of which for sampling using an adhesive layer is brought into contact with the object to be examined, then glued onto a glass slide for further examination under a microscope 1,

It is also known a sampling device comprising a rod with a wedge tip and an adhesive tape 2 disposed on the tip with an adhesive side out.

The use of the known device for sampling does not provide a high productivity and the required sanitary and hygienic displays. conditions of labor. in connection with the need for a network of adhesive tape and the use of glass slides for each sampling, and also due to the fact that the use of a known device does not exclude the possibility

1 contact of the inspected object with is. an investigator.

The object of the invention is to increase productivity and improve working conditions.

This goal is achieved by the fact that in a sampling device containing a rod with a wedge tip and adhesive tape located on this tip with an adhesive side out, the rod is provided with a reel mounted on. its end face is opposite to the wedge tip, and is mounted for reciprocating movement in the housing, on which coils for sticky lelta are fixed opposite each other, while the rod has a through axial passage for the passage of adhesive tape, and on the housing there are elements for separating njo6.

The elements for separating the samples are in the form of serrated perforators.

1 shows a sampling device, a general view; Fig. 2 shows a sample element; FIG. 3 shows a spool knot dp of receiving an adhesive tape of a sampling device.

; The device for sampling comprises a housing 1 having a through opening for a rod 2 with a wedge tip

NICOM 3, fixed one opposite the other coil 4 for rolls 5 with adhesive tape b, a longitudinal groove 7 in which the travel stop 8 of the rod 2 moves, the elements for separating the samples 9, Made in the form of toothed perforators. In rod 2 with a Kli new tip 3, there is a through axial channel 10 for guiding adhesive tape 6, and at the end of rod 2,

opposite the wedge tip 3, a casing 11 with a beanbag 12 is mounted for winding glued together one another strips of adhesive tape -b. The reel 12 is mounted on the same axis and is rigidly connected; with a ratchet wheel 13, to which the dog 15 is pressed by the spring 14, and is driven by the flywheel 16.

The sampling device operates as follows.

Before the beginning of the sampling, the coils 4 are installed on the rolls 5, orienting them so that when unwinding the adhesive tape from them, the latter will be turned with the adhesive side out. The ends of the adhesive tapes 6 are fastened together, pass through the through axial channel 10 of the rod 2, fasten them to the reel 12 and use the flywheel 16 to tighten the adhesive tape b so that it njjoTHO and uniformly clings wedge tip 3 of the rod 2 on both sides from the through axial channel 10, and the rod 2 was moved in the housing 1 all the way to the extreme rear (initial) position.

For sampling the rod 2 is pushed from the housing 1 into the working position. forward until it stops, while the sticky tape 6 is unwound from the rolls 5 and tightly fits the wedge tip 3 of the rod 2. Then the wedge tip 3 of the rod 2 is brought into contact with the object being examined, then, turning the flywheel 16, the rod 2, sata as far as possible into the rearmost position (is (starting position)), winding adhesive tapes; 6 onto a bobbin 12. As a result of gluing together adhesive tapes 6, the selected sample is completely isolated from the external environment, during the movement of the rod 2 into the extreme back (initial) position of limes and the tape b, winding on the reel 12, is lowered onto the separation elements of the samples 9 mounted on the body 1. made in the form of toothed perforators and leaving marks on the adhesive tape b (holes, which denote the border between the selected ones: samples. The presence of the ratchet wheel 13 with the pawl 15. Prevents the unwinding of the adhesive tape b from the reel IS when the rod 2 is moved to the working position. this ensures uniform unwinding of adhesive tape b from rolls 5 for each subsequent sampling operation.

At the end of the examination of a given group of objects, with incomplete use of adhesive tape b from the layers 5, the adhesive tapes 6 glued together between themselves are cut off at the wedge tip 3 of the rod 2 and wound a free section on the reel 12, which is then removed from the sampling device and sent for examination.

The ends of the remaining on the rolls 5 of the adhesive tape b are fastened together. Pass through the through axial channel 10 of the rod 2 and fix them on the reel 12f as described above. The device is ready for further testing.

 the use of the proposed sampling device provides improved productivity and improved working conditions due to the elimination of the need for tape sections and slides for each sampling, as well as the exclusion of contact with the researched object. Sequential registration of the surveyed objects allows mass sampling with high performance.
