Abstract

A tracheal cannula prevents the ingress of saliva into a patient's bronchial passage who is unable to swallow. The tracheal cannula consists of two tubes (14, 15) that link the patient's bronchial passages (10, 11) with the ambient air. The tubes discharge via a saliva and mucous trap (21) located within a housing.

Description

The The present invention relates to a tracheostomy tube which can be used in medical technology as an aid. It is designed to prevent saliva and mucus from entering the trachea Patients who can no longer swallow, enters.

With usual tracheostomy with only one pass, which is currently state of the art it neither possible easy to talk and to breathe through the mouth and nose. There are indeed cannulas, which are fenestrated, i. there is an opening in the cannula which allow speaking and breathing through the mouth and nose, but a protection for the aspiration (ingestion) of saliva is not there.

When next Problem with conventional cannulas with only one air passage is the leaching of the bronchial mucus to call. The mucus is first coughed out, but remains in the front area of the cannula be liable. At the next Inhalation, however, this is sucked back and back into the Lungs transported. This promotes pneumonia and unnecessary aspiration the lungs would be required.

One Another problem with using this conventional cannula is the non ventilation of the mouth and throat, which often colonize germs and bacteria, which in turn makes the patient unnecessary strain.

Also the constant Change of "wet noses", a kind of air filter, which often clog up by caked up mucus could be avoided.

Here The invention aims to remedy this. It is accordingly the Invention is based on the object of providing a tracheostomy tube, which eliminates the aforementioned disadvantages or at least very much limits.

Is solved this task according to the invention by the features specified in the characterizing part of the main claim, wherein in terms of advantageous embodiments of the invention the features of the claims is referenced.

To According to the invention, the tracheostomy tube consists of two tubes, the the trachea the patient with the outside world connect. Through these tubes will the breathing air during inhalation and also exhaled. According to the advantageous Embodiment of the invention open the tubes Outside in a liquid separator. There, the breathing air is cleaned of saliva and mucus.

Corresponding an expedient embodiment includes the liquid separator a housing, which is divided by a cutting disc into two chambers, wherein in each case one chamber opens one of the tubes. Penetrates vomit or food into the tube A, this is withheld by a cutting disc and can not in the other tube reach; so be aspirated. The advantageous arrangement of Safety valve on the housing fixes the risk of suffocation. It opens when tube A clogs is, and still allows inhalation through tube B. When exhaling closes the valve returns and the patient has the possibility of constipation herauszuhusten. In the lower part of the liquid separator can a Cock for the removal of the deposited material may be provided.

Further Details, advantages and features essential to the invention result from the following detailed description of a preferred embodiment with reference to the attached Drawings. Showing:

1 a vertical section through the tracheostomy tube and

2 a section along the section line C-D of 1

As it turned out 1 results are in the trachea 10 the patient has two tubes 14 and 15 introduced. One of the tubes, namely the tube 15 , is over an inflatable rubber ring 12 into the trachea 10 blocked. A ball pump 13 is provided to the rubber ring 12 inflate and thus the cannula in the trachea 10 and 11 to block. The lower part 11 The trachea connects to the lungs.

Outside, the tube opens 14 and 15 in a generally with the reference number 21 identified liquid separator.

The liquid separator 21 includes a housing 16 passing through a cutting disc 17 in two chambers 22 and 23 is under-divided. The tube 14 flows into the chamber 22 while the tube 15 in the chamber 23 beyond the cutting disc 17 empties.

The housing 16 carries in its front area a safety valve 18 , which excludes the risk of suffocation of the patient, if Erbro Chenes or food enters the tube. It opens at constipation and allows for inhalation while occluding on exhalation, allowing it to exhale through the tube 14 is possible.

In the lower part of the case 16 , the liquid separator 21 , a tap or a drain valve is provided, over which (s) deposited material 20 (see point 2 ) can be deducted.

These Invention could conventional cannulas replace and help to rehabilitate tracheotomized patients be in clinics and be distributed there.
