Abstract

 An injection needle containing a tubular body with a cannula and a pointed distal end, characterized in that marks on the introduction of the needle into the nasal cavity are marked on the tubular body and a depth gauge for introducing the needle into the nasal cavity is made in the form of a ball of elastic material, and the distal end of the tubular body bent 30 ° relative to its longitudinal axis to a length of 5 mm.

Description

The utility model relates to medicine and is intended for the injection of drugs, mainly in otorhinolaryngology for injection into the posterior end of the lower nasal concha.

Known injection needle containing a tubular body with a cannula at the proximal end [1].

The disadvantage of this needle is the inconvenience of its use in otorhinolaryngology.

Known needle containing a tubular body with a cannula, a blind end and a number of holes along the length of the body [2].

The disadvantage of this needle is the inability to use it for injection into the posterior end of the lower nasal concha.

Known needle, consisting of a tube curved along the helix with a cannula and a pointed end [3].

The disadvantage of this needle is the impossibility of its use in otorhinolaryngology.

Known injection needle containing a tubular body with a pointed distal end and a cannula [4].

The disadvantage of this injection needle is the complexity of injecting into the posterior end of the lower nasal concha.

Known injection needle containing a tubular body with a cannula [5].

The disadvantage of this needle is the increased complexity of its use in otorhinolaryngology.

Known needle containing a tubular body and a cannula [6].

The disadvantage of this needle is the inconvenience of its use in otorhinolaryngology.

Known injection needle containing a tubular body with a cannula and a pointed end [7].

The disadvantage of this needle is the inconvenience and complexity of injections into the posterior end of the lower nasal concha, as well as the possibility of injury to the tissue of the lower nasal concha.

The purpose of creating a utility model is to reduce the complexity, simplify the production of injections into the posterior end of the inferior nasal concha, accurately localize the injection site and reduce the possibility of injury to tissues of the nasal cavity.

This goal is achieved by the fact that labels are placed on the tubular body to determine the depth of insertion of the needle into the nasal cavity and a limiter for the depth of insertion of the needle into the nasal cavity is installed, made in the form of a ball of elastic material, and the distal end of the tubular body is bent 30 ° relative to its longitudinal axis for a length of 5 mm.

Comparison of the proposed injection needle with other known in the field of medicine, showed its compliance with the criteria of a utility model.

The utility model is illustrated by graphic material, which depicts the inventive injection needle, a General view.

The injection needle contains a tubular body 1 with a cannula 2 at the proximal end 3 and a pointed end 4 at the distal portion 5. On the tubular body 1 there is a limiter 6 for introducing the needle into the nasal concha, made in the form of a ball of elastic material (such as soft rubber or polymer material) . A scale 8 is applied to the tubular body 1 to determine the depth of insertion of the needle into the nasal cavity.

The distal end 7 of the tubular body to a length L of 5 mm is bent relative to the longitudinal axis of the tubular body by an angle α = 30 °.

One of the known methods determines the length of the nasal concha of the patient. The limiter 6 is placed at a predetermined distance from the distal end of the needle.

The pointed end 4 of the tubular body injects the drug into the desired area of the posterior lower nasal concha.

The presence of a bent distal end 4 of the tubular body allows with high accuracy and with minimal labor to inject drugs into the posterior end of the lower part of the turbinate.

The implementation of the limiter in the form of a ball of elastic material allows it to be securely fixed on the tubular body of the needle.

The proposed utility model has a simplicity of design, reliable and efficient in operation. Using the proposed injection needle allows you to exclude the possibility of injury to the tissues of the nose, to simplify and reduce the complexity of the injection of drugs into the posterior end of the lower nasal turbinate, to accurately localize the injection site.
