Description

The invention relates to medical technology, namely, otolaryngology fiboors and instruments for medical examination of body cavities by inspection, and can be used when examining the oral cavity and pharynx of a person in the extremity of additional light sources.

The purpose of the invention is to improve the visibility of vision.

FIG. shows an instrument for examining the oral cavity and pharynx with an autonomous power source, an incision; in fig. 2 is an instrument for examining the oral cavity and pharynx with an external power source, incision.

The device includes a housing 1, on which the bush 2 is screwed. In the bush 2, a replaceable 1-Ppatel 3, made of a), is embedded; The non-working device for PSL at P1patel 3 is made in the form of a focon, at the end of which a spherical recess 4 is made, and its working end B is flat and in cross section it has the shape of a rectangle with rounded corners with a width equal to the diameter of the end A, and that is it; 5-6 mm. Between the housing 1 and the sleeve 2 is inserted an insulation washer 5 into which the lamp 6 is screwed, which serves as a light source. The insulating washer 5 is fixed j. iaHKa 7, having an electrical contact with the renewal of C lamp base 6, springs are attached to case i from the inside; 8 i: using a rivet 9, whereby the spring 8 has electrical contact with the housing 1. Under the spring 8, a button 10 is inserted into the opening of the housing 1. A strip 7, a spring 8 and a button 10 together form a switch. In case 1, two serially connected dry elements 11 n 2 of type 3i6, serv. 1, and their source iitani 5 are also installed. The positive pole of the element 11 has an electrical contact with the output D of the lamp 6. The elements 1 and 12 are pressed to La. 6 with the power screwed onto the body 1 thread

the base plate 13 and the spring 14. The negative pole of the element 12 is connected by a spring 1-4, the cover 13 and the body is electrically connected to the dinner party 8.

A light source is located in the center of the curvature of the dimple 4. This provides the entry into the spatula p, mat, single beam by beam, concentration of beam by focon and dissn-ie output spatula of spatula, on which cylindrical lens 15 is made. -3 times. In addition, paBnoMepfioe illumination of the studied height is provided.

The device is used as follows.
