Abstract

Y-thorax drainage for use in thoracic surgery, characterized by a Y-shaped part, the two legs of which can be positioned on two different target areas in the pleural cavity (pleural and diaphragmatic angle) for air and fluid drainage.

Description

1. State of the art:

• 1.1. Chest tubes are used in thoracic surgery Intervention, the opening the pleural cavity in the pleural cavity used. They are used for postoperative air and fluid drainage, after a thorax surgical procedure a full development to allow the lungs and so the lung function by drainage (drainage) of liquids (Pleural fluid, Secretions, blood, pus) and air. Infections in the pleural cavity, pneumonia but also pulmonary function restriction Compression and lack of expansion of the lungs will be prevented.
• 1.2. There are different drainage models, among others and curved chest drainages. These are discharged from the pleural cavity (thorax) and to a drainage container connected, connected to a suction system for manufacturing of negative pressure allows the complete expansion of the lungs.

The straight chest drainage is placed in the pleura (thorax tip). It serves primarily the air drainage. The curved thoracic drainage is placed backwards / downwards in the so-called recessus phrenicocostalis (diaphragmatic angle), ie in the pleural space between the diaphragm and ribs. Its main purpose is the drainage of liquids ( 1 ).

If One or two chest drains are used, hanging next to the actually medical indication also from the surgeon. In Not a few thoracic surgical centers will default to two Drains inserted for optimal air and fluid drainage to reach.

2. Disadvantages of the previous application of chest drains:

• 2.1. When inserting only a chest drain, which is usually inserted into the pleura, becomes the liquid, by gravity into the lower, rear diaphragm angle expires, bad or only incomplete drained. This can lead to infection or splintering of the pleural cavity, which with restrictions associated with lung function. In contrast, is but the use of only one drainage more comfortable for the patient and less painful, as only a thorax incision (cut in the Rib space) is required to drain the drainage. Because the drainage outside of the thorax connected to the drainage container The use of only one drainage is also safer. So there is a lower risk of drainage dislocation.
• 2.2. Two drains must be drained via two thorax incisions (two incisions in the intercostal space). A second incision causes additional pain. Furthermore, the second drainage is usually behind the first one, causing the patient to lie on it more often, which also causes pain ( 2 ).

The Drains are directed either into two separate drainage tanks or outside of the thorax a connector connected to each other, then to a common drainage tank conduct. Through two drainage tanks is the patient is immobile. Furthermore, there is the high number at additional Connectors, an increased Risk of dislocation, which puts patients in life-threatening situations, such as a voltage pneumothorax can bring.

3. Problem and claim

• 3.1. The specified in claim invention the problem is based on the number of chest drains for adequate air, and fluid drainage the pleural cavity to reduce drainage.
• 3.2. This problem is solved by the features listed in the claim like Y-thorax drainage solved with simple discharge from the thorax.
• 3.3. The advantage achieved by the invention is that the pleural (in the thorax) Y-shaped drainage part of the pleura and reached the diaphragmatic angle (Phrenicocostal recess) equally and drained. The pleural (intrathoracic) located Y-shaped part will be over one discharged simple drainage. With a single required Drainage incision and only a drainage connection to a drainage container accounts additional Thoracic incisions, pain and disconnection problems.

3 shows the Y-shaped part of the newly developed Y-thorax drainage with thighs for pleura ( 1 ) and diaphragm angle ( 2 ) as well as the common drainage discharge ( 3 ) from the thorax.

4. Application

The Y-thoracic drainage is inserted into the pleural cavity at the end of the surgical procedure and the Y-shaped (pleural / intrathoracic) part is positioned with one leg in the pleura and one leg in the posterior phrenicocostal recess. The simple common drainage part is made via an incision in the intercostal space in the usual thoracic surgical procedure discharged from the thorax.
