The invention relates to sampling devices and can be used, in particular, in the engineering of microbiology and dentistry.

The purpose of the invention is to increase the representativeness by taking a sample from the entire surface of the cavity.

The drawing shows a device for sampling from hard-to-reach cavities.

The casing 1 is mounted with the possibility of translational-rotational movement of the rod 2, the movable part 3 of which is pivotally connected to the main part of the rod 2 and the thrust 4 with the body 1 A spring 5 is installed between the body 1 and the rod 2 to return the latter to its extreme position. The washer 6 is rigidly connected to the end of the stem 2. The cotton swab 7 is mounted on a replaceable rod, the end 8 and the working 9 parts of which are connected by an elastic link, for example a spring 10. The latch 1 fixes the end part 8 of the replaceable rod relative to the movable part 3 of the stem 2. The loop 12, installed with the possibility of moving along the working part 9 of the replaceable rod, fixes the tampon 7 on it.

The device works as follows.

 When used in dentistry, the thumb and forefinger of the left hand grip the device body 1, and the thumb and right fingers grab the washer 6. The movable part 3 of the stem 2 together with the fixed loop 12 and cotton swab 7 is inserted into the maxillary sinus through the perforation hole lung extracted tooth. A swab is used to collect microbiological material from the upper wall of the maxillary sinus. Then, with the thumb of the right hand, the washer 6 is displaced upwards, and with it the rod 2, while the movable part 3 of the rod 2 together with the tampon 7 is displaced downward to the bottom of the sinus. Additional material is taken.

Then the washer 6 is released and the movable part 3 of the rod 2 is installed in its original position by the spring 5. The device is shifted around the axis by 180 °, does not remove it from the sinus. The previous manipulation is repeated and the material is taken from the bottom of the maxillary sinus, but from the opposite side. Then, the movable part 3 of the stem 2 is installed at an angle of 45 ° and, rotating the device around the axis through 180 °, material is taken for microbiological examination from all the side walls of the maxillary sinus. All irregularities of the side walls of the sinus freely pass through the spring 10 of the movable part 3 of the rod 2. Remove the movable part 3 of the rod 2 with a sterile clip, place it in a test tube with 5 ml of sterile saline solution, cover with a sterile stopper and supply the material for microbiological examination.

Claims (2)

1. A device for sampling from hard-to-reach cavities, containing a stem with a body and a tampon, is necessary because, in order to increase its representativeness by taking a sample from the entire cavity surface, it is equipped with a replaceable rod with a loop for fixing a cotton wool. tampon, t goy, and the stock consists of a movable and the main part, the movable part of the rod is pivotally connected to the main part and is tight with the body, and the movable part of the rod is equipped with a replaceable rod, made in the form of the end non-working parts, connected by an elastic link. 2. A device according to claim 1, characterized in that the loop is adapted to move along the working part of the rod.
