Insertion aid for percutaneous tracheostomy

Abstract

A device for inserting a tracheal tube into a tracheostomy has an insertion aid with a shaft (6, 6', 14) which can be inserted through the tracheal tube, and a conical tip (2, 13) which is or can be joined to the tracheal tube. In order to provide a device for inserting a tracheal tube which considerably reduces the risk of injury when inserting the tracheal tube, and which makes the insertion process easier, the inserted tube being highly comfortable even with a long-term use, keeping low the danger of injuries or sore points in the trachea, the insertion aid according to the invention has a conical tip (2, 13) which can have a small base diameter in a first state and a large base diameter in a second state. The insertion aid includes a section (6', 14) adjacent to the conical tip (2) whose diameter corresponds at the most to the inner diameter of a tracheal tube (1) to be inserted by means of the insertion aid, the small base diameter of the conical tip also being at the most equal to the inner diameter of the tracheal tube, while the large base diameter of the conical tip is larger than the inner diameter of the tracheal tube and preferably corresponds to approximately the outer diameter of the tracheal tube to be inserted with the insertion aid.

Description

technical field [0001] The present invention relates to a device for introducing a tracheostomy tube into a tracheostomy by means of an insertion aid having a main stem that can be introduced through the tracheostomy tube and a stem that can be the stem or be connected to the stem. Tapered end. Background technique [0002] A tracheostomy is one of the oldest procedures in medical history. The origin of this technique dates back to ancient times. In a standard tracheostomy, an artificial passage to the trachea is surgically created below the larynx, usually between the first and second or second and third tracheal rings. A so-called tracheostomy tube is fitted around this artificial opening to maintain breathing. Medical indications such as the need for prolonged breathing make this technique still in demand today. As an alternative to surgery, minimally invasive punch techniques have been developed in recent decades. Therefore, especially Ciaglia's percutaneous dilated...

This can lead to cricoid cartilage fragmentation

[0009] Although the edge 9 of the tracheostomy tube 1 can also be chamfered in the region of the tapered end 8, this means that after the insertion aid and thus the tapered end 8 have been removed, a rather sharp inner edge is formed. The distal end of the tracheostomy tube 1 is removed, which in turn can cause injury or trauma if it comes into contact with the sensitive trachea, thereby also causing pain which, for the patient, makes it difficult to keep such a trachea inserted for a long time. Stoma tubes are even more unpleasant
