Abstract

Flexible tracheal cannula shield for mounting a tracheal cannula (3) with a tracheostomy tube ring (2), characterized in that an air cushion shield (1), (9), (13), connected to an air hose (6) and valve (4), by air supply ( 5) variably controls the flexibility of the air volume (14).

Description

The invention includes a flexible cannula shield for tubes, cannulas and especially for tracheal cannulas, consisting of an air cushion ring, for avoiding the effect of vertical and horizontal pressure on the cannula and the tracheostoma or trachea during neck movements through the cannula carrier. In particular, the invention is intended to allow the mobility of the cannula shield in the vertical and horizontal plane of the neck movement in all directions free flow, without the cannula exerts pressure on the trachea.

A tracheostomy is a surgical procedure in which an opening is made through the anterior surface of the neck into the trachea. The opening is called a tracheostoma. A cannula may then be provided which is then inserted into the stoma to keep the stoma open and provide a breathing air passage and may extend through the tracheostoma and into the trachea. The cannula may also serve to secure various devices, including filters, stoma valves, voice prostheses and the like, either at their anterior or tracheal openings. For example, a heat-moisture exchange filter can be used in this way. In a person whose breathing is functioning normally, the nose and the inner mucous membranes of the nasal cavity have important functions for the treatment of the inhaled air. The tortuous passages and rich blood supply serve to increase both the temperature and the humidity of the inspired air to minimize the difference of these parameters from those of the surface of the lung. Normally, part of the heat and moisture from the exhaled air is released into the atmosphere before it is released. The inner mucosa of the nasal passages is also used to remove suspended matter, such. Fine dust particles, air contaminants and microorganisms from the inspired air stream, and the cilia carry mucus and particles away from the lungs. However, if a patient had a laryngectomy, the trachea is no longer connected to the pharynx, but is redirected to the tracheostome. All inhaled air enters the lungs via the tracheostoma. The nose and upper part of the respiratory tract over the stoma are not effectively involved in the inhalation process. For this reason, it is often desirable to install heat and moisture exchange filters in a laryngectomy patient. These can be conveniently placed on an outer end of the stoma sitting cannula. Similarly, a speaking valve can also be attached. Another consequence of laryngectomy is that speech is no longer available through the normal process of passing air through the vocal cords of the larynx. Where clinical preconditions allow, it is clearly in the patient's interest to restore the ability to speak.

In the DE 10 392 887 T5 For example, a tracheostoma cannula attachment for assisting attachment to a cannula in a stoma of a tracheostoma patient, comprising a generally planar flat member provided with an opening sized and shaped to be press-fitted for seating on a channel portion of a tracheostoma cannula. Thus, there is provided a posterior attachment surface which, in use, is adapted to abut the skin of the tracheostoma patient in the vicinity of the stoma, the material of which the flat article is made having a sticky gel material at least in the vicinity of the attachment surface. Here, the attachment serves to seal and lock the cannula.

The DE 19 627 112 A1 describes an epithesis consisting of a shell, which in turn is adapted to the back of a body part and the front of the desired body surface and a filling filling the shell, wherein the filling of an elastic material having a density of d <0.25 g / m ³ exists.

In the AS 10 55 176 supplements are described on the human body.

In the DE 20 2010 004 455.1 a foam shield is described.

Furthermore, so-called twist cannulas are known which have a pivotable in two axes, hard cannula shield.

All other tracheal cannulas have cannula plates that are made of a hard plastic or less hard plastic and barely fend off vertical and horizontal forces in a neck movement on the cannula in the trachea.

It will be appreciated that for all tracheostomy tubes, a particular soft, padded cannula shield may be very useful for avoiding pressure on the cannula and trachea.

Also desirable in this context is that the cannula shield simultaneously balances bumps on the stoma and in a generally airtight manner through the soft air cushion, during inhalation and exhalation, the air can not escape sideways on the cannula and needle shield uncontrollably.

The object of the present invention is to use a cannula shield which compensates for unevenness by a soft air cushion on the stoma, effectively seals against lateral air and avoids vertical and horizontal forces acting on the cannula and trachea by the pad thickness of the cannula shield. The special feature is that an air cushion, embedded in a flexible plastic film, variably adjustable by air supply and valve control, is applied. The air cushion or the air cushion shield is mounted with a receptacle for a cannula and has for attachment to the neck by means of retaining straps slots in a material flange. The air cushion should have a thickness of at least 6-8 mm and always be 4-6 mm larger in width than the diameter of the cannula holder. The invention can be used as an air ring or cannula shield.

The following is a description of the invention, by way of example only, with reference to the figures schematically illustrated.

In the 1 becomes an air cushion shield ( 1 ) with a neck curvature ( 8th ) and a slot flange ( 10 ) with tether slots ( 7 ). The bubble shield ( 1 ) with a tracheal cannula ring ( 2 ) connected cohesively. The tracheostomy tube ( 3 ) is cohesively in Trachealkanülenring ( 2 ) assembled. The bubble ring ( 1 ) has an air volume ( 14 ), which by air supply ( 5 ) through a valve ( 4 ) and an air hose ( 6 ) can be filled in the desired flexibility. This avoids the formation of pressure points in the tracheostoma and neck of the patient. By optimizing the air supply ( 5 ) may also seal on the tracheostoma.

The 2 shows a rectangular design of the bubble shield ( 9 ). The special feature here is the application of a moisture protection ( 11 ). This moisture protection ( 11 ) is intended to prevent the formation of moisture when the bubble wrap is applied.

The application of a round bubble shield ( 13 ) is in the 3 shown. By forming a flange zone ( 12 ) is a plane for incorporation of tether slots ( 7 ) educated.
