RU88946U1 - TUBE NOZZLE FOR LIGHT-CURING COMPOSITE MATERIAL - Google Patents

Abstract

Tube nozzle for light curing composite material.

This utility model relates to medicine, namely to dentistry, and can be used for accurate dosing of light-cured composite material.

The technical result of this invention is to increase the convenience of filling due to the precise dosage of light-cured composite material, packaged in tubes; reduction of the duration of manipulation when filling defects in the hard tissues of the teeth as a result of a decrease in the time taken to take a portion of the composite material.

The nozzle on the tube for light-cured composite material, contains a housing with retention elements on the outer surface, having a through channel with thread for screwing onto the tube. New in the nozzle on the tube is that the top of the nozzle body is made in the form of a ledge with a height of 1-2.5 mm with a visor 0.1-1.0 mm wide and a horizontal contact pad with an outlet of the through channel, and a cap with retention elements on its outer surface covering the nozzle body.

Description

This utility model relates to medicine, namely to dentistry, and can be used for dispensing light-cured composite material.

Known nozzle on a tube for a composite material of chemical curing, consisting of a housing with a through channel. The housing is made in the form of a protruding cone having a rim in the lower part with retention elements on the outer surface and internal thread for screwing onto a tube with a composite material. Inside the casing is a cone with a catalyst for polymerization [Application EP No. 1749500 A61C 5/06, 02/07/2007].

The disadvantage of this nozzle is its unsuitability for measuring the exact portion of the composite material packaged in tubes, a dispensing device is not provided.

The technical result of this utility model is to increase the convenience of filling, due to the accurate dosing of light-cured composite material, packaged in tubes; reduction of the duration of manipulation when filling defects in the hard tissues of the teeth as a result of a decrease in the time taken to take a portion of the composite material.

The technical result is achieved in that in the nozzle on the tube for a light-cured composite material containing a housing with retention elements on the outer surface, having a through channel with thread for screwing onto the tube, a distinctive feature is that the top of the nozzle body is made in the form of a step 1- high 2.5 mm with a visor 0.1-1.0 mm wide, a horizontal contact pad having an outlet of the through channel and a cap with retention elements on the outer surface covering the nozzle body.

The length of the step is 1-2.5 mm, due to the fact that the thickness of the portion of the light-cured composite material that photopolymerization lamps can enlighten and completely harden is 2.5 mm.

The peak prevents the exit of the material beyond the ledge and thereby prevents accidental overdose of the material.

The nozzle on the tube for the light-cured composite material is intended for accurate dosing of the light-cured composite material, (see Fig. 1 (a, b) - body. Fig. 2 - cap) and consists of a body (1) with thread (2) for fixing on tube with a composite light-cured material having a through channel (3), which contains in the upper part a ledge (4) with a height of at least 1 mm and not more than 2.5 mm with a visor (5) 0.1-1.0 mm wide, for determine the boundaries of the supplied light-cured composite material, the outlet (6) of arbitrary shape, g horizontal contact pad (7), which serves to separate portions of the composite material. On the outer surface of the casing (1), the reception elements (8) are applied for ease of use.

The nozzle also has a cap (9) with retention elements (10) applied to its outer surface. The cap (9) closes the housing (1), protects the light-cured composite material from self-polymerization under the influence of light, as well as from the ingress of pollution from the external environment.

A nozzle on a tube for a light-cured composite material can be made of either polymeric materials or metal or a combination thereof.

The procedure for working with the nozzle includes: screwing the nozzle onto the tube with a light-cured composite material, removing the cap and squeezing the composite material from the tube. When the material reaches the peak of the ledge, they cut off a portion of the material with a tool, relying on a horizontal contact pad. The separated portion is used for filling.

Thus, the nozzle on the tube for the light-cured composite material can reduce the duration of manipulation when filling defects in hard tissues of the teeth, due to the exact dosage optimal for the polymerization of a portion of the light-cured composite material, and to improve the quality of the filling, because the optimum depth to which the curing lamps can cure the material is 1-2.5 mm.

Claims (1)

A nozzle on a tube for a light-cured composite material, comprising a body with retention elements on the outer surface, having a through channel with thread for screwing onto the tube, characterized in that the top of the nozzle body is made in the form of a step 1-2 to 2.5 mm high with a visor width of 0, 1-1.0 mm and a horizontal contact pad with an outlet of the through channel, and a cap with retention elements on its outer surface covering the nozzle body.
