Description

The utility model relates to dentistry, and is a device for measuring the length and width of the tongue. A device is known for measuring the width and length of the tongue (see Khoroshilkina F.Ya. et al. Orthodontics, Book IV, Moscow, 2005, p. 118) taken as a prototype, containing a body in the form of a meter with spherical ends and scale ruler.

A disadvantage of the known device is that it is impossible to accurately measure the length and width of the tongue, because the tongue takes a curved shape during measurement.

The objective of the claimed utility model is to increase the accuracy and convenience of measurement.

The problem is solved in that in the device for measuring the size of the tongue, containing the housing and a scale ruler, the housing is made in the form of a curved wire forming an isosceles triangle, the sides of which are fastened to each other at the apex and extend beyond the apex, while the base of the triangle is installed a flexible metal ligature with the possibility of longitudinal movement relative to this base, and a scale ruler is installed between the extensions of the sides of the triangle. Notches are made at the vertices at the base of the triangle.

The claimed device has a convenient design. It does not injure the tongue and mucous membranes of the oral cavity, being thereby absolutely safe. Measurements can be carried out not only with the extended position of the tongue, but also directly in the oral cavity. With this device, the speed and accuracy of measuring the size of the tongue is increased.

The device is illustrated in the drawing, which shows:

figure 1 - General view of the device (at the time of measuring the length of the tongue);

figure 2 is the same (at the time of measuring the width of the tongue).

The claimed device comprises a housing 1 (Fig. 1), made in the form of a curved orthodontic wire with a diameter of 1.0-1.5 mm, forming an isosceles triangle, the sides 2 and 3 of which are fastened (for example, by soldering) to each other at apex 4 and continue beyond given top. Between extensions 5 and 6 of sides 2 and 3, a scale ruler 7 is installed (for example, a metal tape on which graph paper is fixed). A flexible metal ligature 9 (0.3-0.5 mm in diameter) is installed on the base of the triangle 8 with the possibility of longitudinal movement relative to this base 8. At the vertices 10 and 11, notches (not shown) are made to prevent the ligature 9 from sliding down the sides 2 and 3. The housing 1 of the measuring device may have various sizes, depending on the size of the tongue (the language of the child or adult).

The length of the tongue is measured from the mushroom-shaped papillae 12 (Fig. 1) to the tip 13 of the tongue with its maximum extension. In this position, the tongue has a convex shape, and a flexible metal ligature repeats its contour, tightly fitting to the tongue. At the tip of the tongue 13, the ligature 9 is bent, the device is removed from the oral cavity and the length of the ligature 9 is measured to its bend. Thus, the measurement of the length of the tongue produced by the claimed device is more accurate compared to known methods and devices. To measure the width of the tongue, the device is superimposed on the tongue and using the ligature 9, moved along the base 8 (figure 2), and a scale bar 7, measure the width of the tongue. Moreover, the width of the tongue can be measured both inside the oral cavity and outside. This simplifies the measurement process and increases its comfort.

A device for measuring the size of the tongue, comprising a housing and a scale ruler, characterized in that the housing is made in the form of a curved wire forming an isosceles triangle, the sides of which are fastened to each other at the apex and extend beyond the apex, while flexible a metal ligature with the possibility of longitudinal movement relative to this base, and a scale ruler is installed between the extensions of the sides of the triangle. 2. A device for measuring, characterized in that in the vertices at the base of the triangle notches are made.
