Abstract

With a hand grip and without undesirable interruption of the intubation process an endotracheal tube (8) can be inserted in to the trachea of the patient with simultaneous suction of body fluids if required. A medical standard suction device can be activated either to suck body fluids via the endotracheal tube or air via a connection (6) by alternately closing and opening the connection with the aid of the finger of the operator. Under conditions of acute narcosis, the patient own breathing is eliminated. In this case, it is of great importance that the intubation process proceed as quickly as possible, thus protecting the air tracts of the patient.

Description

10 15 20 25 30 35 40 45 512 885 The purpose of the invention.

The present invention aims to streamline and facilitate intubation of patients by preventing or restricting aspiration to the lungs associated with initiation and anesthesia of the patient to the desired depth of anesthesia.

Another purpose is to reduce the subsequent morbidity and mortality that can occur because aspiration is a real complication of acute anesthesia.

Another purpose is that the anesthetist can handle intubation on his own and at the same time vacuuming the throat without the assistance of other staff.

Brief description of the idea of recovery.

The above objects and further objects are achieved by a device according to the invention which exhibits the features stated in the claims.

The device according to the invention is characterized by connecting one to a plastic coupling endotracheal tube with metal conductor and a connection for standard medical suction, on one such that intubation and cleansing of the pharynx can take place during the same operation by controlling the suction power using a ger inger, so that when suction power is required the absorption of body fluids precisely in the area where the suction effect is most required, namely at the tip of the endotracheal tube and where the suction power is higher than at conventional suction coupling by using the coarse endotracheal tube in the intubation process as an extended straw to the standard medical craving.

Brief description of the accompanying drawings.

Fig. 1 shows in a parallel perspective the connection between a standard medical suction and endotracheal tube.

Fig. 2 shows in a parallel perspective how the endotracheal tube and the medical one the standard vacuum is connected to a working unit.

Detailed description of the invention.

In order for the description to be simpler and as far as possible to avoid misunderstandings, first some concepts are defined that will be used in the description: endotracheal tube means a plastic tube that is inserted into the trachea and which ensures the air supply to the lungs for anesthetized patients. - intubation means when the above endotracheal tube is inserted into the trachea. - aspiration refers to the inhalation of gastric contents or blood into the lungs. - induction of anesthesia refers to the initiation and anesthesia of the patient to the desired anesthesia. 10 15 20 25 30 35 40 45 512 885 larygoscope refers to an instrument that lasts throughout the intubation process return the patient's tongue and other tissues for visibility to the vocal cords be free. - Rapid Sequence Education, RSI, refers to a technology that reduces the risk of aspiration.

Fig. 1 shows the integrated plastic coupling (1) for connection (2) of medical standard suction, connection (3) for endotracheal tube, connection (4) with tight rubber top (5) for metal conductor and connection (6) which, with the help of the operator's finger, controls the suction power either via connection (3) if connection (6) is sealed with a eller nger or controlled the suction power via connection (6) if the operator does not seal: connection (6) with a fi inger.

Fig. 2 shows the plastic coupling (1) with connected peripheral equipment in the form of a hose (7) standard medical suction and a part of the plastic tube (8) belonging to the endotracheal tube.

In addition, a metal conductor (9) is inserted into the endotracheal tube (8) via the tight-fitting rubber tops (5).

If an emergency procedure must be performed, e.g. in the event of a traction injury, the RSI technology is used.

RSI technology means that the patient is given sedatives and muscle relaxants in a consequence without checking that the patient can breathe on their own. To be able to intubate the patient's own breathing must stop, which causes medication with the above said muscle relaxant drug. Because the patient's breathing has stopped the intubation process under strong time pressure.

Using a larygoscope inserted into the pharynx, lift the tongue and other tissues away to make the vocal cords visible. The anesthesiologist must throughout the intubation process holding the larygoscope in one hand and thus that hand is locked throughout the intubation process. A metal conductor is used to facilitate intubation (9) to stiffen the endotracheal tube (8) which is pulled up as fast as the endotracheal tube (8) passed the vocal cords.

Via connection (2), the standard medical suction is switched on throughout the process with intubation. If difficulties occur during intubation in the form of vomiting or blood fl fate, the operator can activate suction denial via the endotracheal tube (8) by closing connection (6) with one finger. When varying body fluids are sucked away can the intubation continues. If additional body fluids need to be sucked away to cope continued intubation, the connection (6) is closed again with a fmger. When connection (6) opened, the medical suction, which is applied to the connection (2), sucks air straight by plastic coupling (1) and connection (6) with no suction object lying on endotracheal tube (8).

Using the endotracheal tube (8) as an elongated suction tube results in aspiration exactly where the need for suction is disturbed, namely at the tip of the endotracheal tube (8).

The above procedure significantly streamlines the intubation process by varying body fluids can be absorbed while the endotracheal tube (8) is inserted into trachea. 10 15 20 25 30 35 40 45 512 885 When intubating with conventional equipment, the intubation must be stopped each time there is a need to absorb body fluids. At e.g. an acute anesthesia with subsequent Surgical procedures can be the time factor to get one positive result of the procedure.

With the above device, the intubation time is shortened when complications occur, i in the form of vomiting or bleeding, during intubation and the risk of aspiration decreases or is limited. The complications after an aspiration are often proportional to the size of the aspiration.

By sealing connections (2) and (4), with e.g. a lid, plastic coupling (1) can be used as a corner piece between respirator and tube.

If, on the other hand, only connection (2) is sealed and a non-return valve is applied to connection (4), For example, the airways of ventilator-bound intensive care patients can be cleaned with a standard suction catheter without disconnecting the respirator. Even br berbroncoscopies, examination of the lungs, can be performed without respiratory patients must be disconnected from the ventilator.

The embodiments described above can, of course, be varied in many ways by those skilled in the art different ways within the framework of the invention tarik.

The field of application can also be extended to areas other than those described.
