Problems solved by technology

Among them, in particular the search for the reflective point at which the percutaneous puncture will be performed: this operation is performed entirely manually without any guidance, so that during the needle introduction process, the same needle may be introduced unnoticed into the blood vessel middle
Another risk associated with the current technique is the possibility of accidentally puncturing the posterior wall of the trachea

Embodiment Construction

[0021] Referring to the example of the figures, the endotracheal tube 1 according to the invention basically comprises a tubular hollow body 10, which may be made of, for example, PVC, silicon PVC or other suitable material.

[0022] exist figure 2 In the example shown, at the proximal end of the catheter 1 a connector 5 of known type is provided which allows connection to a ventilatory aid.

[0023] Provided at the distal end to be inserted into the trachea is a device 3 adapted to emit optical radiation for determining percutaneous illumination (the device is also referred to as an illumination device in this description) integrally formed with the main body of the catheter 1 and adapted to Volume variable device 2 that changes the overall diameter of the catheter (ie, the obstruction in the lumen of the trachea).

[0024] exist Figure 2-4 In , the letter P represents the tracheal wall, and D represents the diameter value of the relevant lumen. These representations are...

Abstract

The invention relates to an endotracheal tube (1), usable in dilating percutaneous tracheostomy operations and comprising a tubular body (10) whose distal end, to be inserted in trachea, is provided with means (3) suitable to emit a light radiation for determining a transcutaneous illumination and with variable volume means (2), integral to said tube (1) and suitable to vary the total diameter of the tube, that is its encumbrance in the lumen of the trachea; tube (1) characterized in that said variable volume means (2) are shaped and / or positioned so that their expansion maintains said means (3) suitable to emit a radiation light substantially near the tracheal wall (P), that is in a position in which the means (3) are disposed substantially in contact with a wall (P) of the same trachea.

Description

technical field [0001] The invention relates to an endotracheal tube. In particular, the catheter of the invention is used for endotracheal intubation prior to performing a percutaneous tracheostomy. Background technique [0002] Tracheostomy is well known as a surgical procedure used to create a connection between the trachea and the outside in patients with primary or intermediate respiratory disease. [0003] The main advantages of this approach are the reduction of respiratory dead space, better adaptation to rational assisted ventilation, and assistance in ventilator "nursing" and "weaning" phases of operation. All of these contribute to a faster recovery. [0004] Among the known tracheostomy methods there are, for example: the typical surgical approach, which provides all planned surgical incisions of the neck followed by a tracheostomy with specific intubation; reverse classics according to Fantoni The percutaneous method, which is achieved by intubating the patie...
