2. A device for receiving contents from the crypt tonsil cavity, comprising a syringe body, a piston with a rod, a curved cannula. with guard plate, distinguished by the fact that, with celibate

The invention relates to medicine, in particular, to otolaryngology, and is intended to obtain the contents of the crypt tonsil cavity for further diagnostic examination.

The purpose of the invention is to obtain content from all parts of the crypt in its pure form and at a given dilution, suitable for subsequent analysis.

FIG. 1 shows a device for obtaining contents from the crypt cavity of the palatine tonsil, a general view of FIG. 2 - limiting the return stroke of the piston, side view.

A device for receiving the contents of the crypt tonsil cavity includes a syringe body 1, a piston with a stem 2 placed in the body 1, a curved cannula 3 with a limiter shield 4, a stem return limiter 5 2. The piston rod 2 has a return spring 6. The end 7 of the working end of the cannula 3 is blunted.

The limiter 5 of the return stroke of the rod 2 has a holder 8 with rings 9 and 10. The holder 8 is fixed on the housing 1. The rings 9 and 10 are intended for placing the device on the index and middle fingers. The spring 6 provides the reciprocating movement of the piston, and the limiter 5 allows you to adjust the volume of the injected and sucked fluid when the syringe body 1 moves in the cage 8. The presence of the spring 6 and the rings 9 and 10 make it possible to manipulate the device with one hand.

To implement the method, a device is assembled after sterilization of its parts.

- By moving the syringe body 1 in the cage 8, the syringe piston is set at a predetermined volume, and when the crypt is received at a given dilution, suitable for subsequent analysis, it is equipped with an age limit for the piston, the piston rod has a spring-loaded stroke, and the end of the working end of the cannula is blunted .

- current 4 on the cannula 3 is shifted depending on the selected depth of immersion. Fill the body 1 of the syringe and the cannula 3 with liquid. In the process of examining the 5 throat of the examined patient, holding the device with index and middle fingers inserted into the rings, enter the folded tip of the cannula 3 under the eye’s eyelet into the mouth of the selected lacunae 3. The clearance between the cannula 3 and the tonsil tissues in the ustal area is covered with a shield 4 , tightly clamping it to the amygdala. In this position, pressing your thumb on

15 piston rod .2 of the syringe, a measured volume of fluid is introduced into the crypt of the amygdala under pressure and, without opening the crypt, relieves pressure on the piston. At the same time, the piston of the syringe returns to its initial position due to the operation of the spring, sucking the suspension of its contents with the injected fluid formed in the cavity of the crypt. In order to obtain a more uniform mixing of the contained crypt with the liquid and consequently a predetermined dilution, do not remove the cannulas from the crypt cavity, the procedure for introducing and sucking is repeated several times, completing it with suction. The material thus obtained is then subjected to microbiological, immunological and cytological study by means of known .

The use of the method and device for obtaining the contents of the crypt of the palatine tonsil crypt provides for obtaining the contents of all crypt departments in a pure form and at a given dilution suitable for subsequent use of the patient to isolate pathogens that support chronic inflammation in tonsillitis, as well as to determine the violation tonsil function in chronic tonsillitis.
