DE202004020109U1 - Tracheostoma tube with adapter carrying extension, comprising particularly soft adapter with finger insertion recesses - Google Patents

Abstract

The tracheostoma tube is designed as a tube (1) comprising a cylindrical or cubic extension (2) attached to its distal end by gluing, welding or screwing, fitted with an adapter (3) for the joining of a valve, a respiratory device, or a speaking valve. The adapter (3) is made of a particularly soft and thermoplastic material sealed airtight against the tube (1). An airtight connecting of the related parts is facilitated by the ribbed inner surface (31). Recesses (4) for the insertion of thumb and forefinger are provided at the outer rim (32) for an easy manipulation.

Description

The The invention relates to a tracheostoma tube with adapter for laryngectomy.

at larger operational Surgery in the upper respiratory tract can be the creation of an artificial breathing hole be necessary in the neck area (tracheostoma), so that the air is below Bypass of mouth and larynx inhaled directly into the lungs becomes.

at Laryngectomy will permanently open this patient's stoma held by a tracheostomy tube is used to stabilize and keep open the new breathing opening.

These tracheostomy mostly consist of foreign and inner tubes and can For example, with a speaking valve, by means of a round bayonet closure attached to the outer cannula is provided with the outer cannula "sieved" and the inner cannula "fenestrated" executed can.

made are the tracheostomy tubes made of metal or medically usable plastics.

The font DE 197 54 432 A1 discloses a speech valve for tracheostomy tubes, in which the tubular outer body is firmly glued to the flange of the inner cannula of the tracheostomy tube or easily assembled with a closure system.

From the Scriptures DE 195 14 433 C1 a tracheostomy cannula for use in a tracheostoma is known, which consists of a tubular outer cannula with cannula shield and a tubular inner cannula, wherein the inner cannula is inserted into the outer cannula and lockable with this at the proximal part.

From the Scriptures DE 196 36 050 A1 a Tracheostomaplatzhalter is known, which consists of a tubular Tracheostomaschenkel and a shield, said the tracheostomy are associated latching means that ensure the recording and fixation of a shield in a variably adjustable distance to the contact surface of the trachea limb to the trachea.

there are the locking means in the form of introduced into the Tracheostomaschenkel Grooves or in the form of applied on the tracheostomy Formed beads.

The German Utility Model 20 2004 007 251.3 discloses a tracheostomy tube consisting of an inner cannula and an outer cannula, wherein the inner cannula has n locking means at its distal end, which is not continuous circular form the cross section of the distal end of the inner tube, but tenon or barb-like from the distal end of the inner tube protrude and form-fitting engage in corresponding recesses / profiles of the outer cannula, where n ≥ 3, so that a twisting of the inner cannula prevents the outer cannula becomes.

alternative this is from the German utility model 20 2004 007 252.1 a tracheostomy tube known from an inner cannula and an outer cannula, wherein the inner cannula via latching means on her outer wall features, the inner cannula a n-angular Cross section, where n ≥ 3 is, and the form-fitting grab into the inner wall of the outer cannula, so that a rotation of the inner cannula to the outer cannula is prevented.

Of the Disadvantage of all known Tracheostomaprothesen / tracheostomy tubes, that the locking systems, latches or locking means for attachment of accessories these parts poorly released from the assembled state, in particular a very bad access with the fingers of one hand at the lock, Locking or locking on the accessory is given.

Of the Invention is therefore the object of the disadvantages of the prior art To avoid the technique, in particular a Tracheostomarohr with a Specify adapter, giving better access with your fingers the hand at the locking, locking or latching point on Accessory is possible as in the prior art.

According to the invention This object is achieved by the characterizing features of the first patent claim solved and supplemented by advantageous embodiments according to the subclaims.

The Essence of the invention is that the distal end of a Tracheostomarohrs is provided with an adapter which at least at its free end has a recess at its edge, by means of which a positive and airtight Accessories such as Trachinaze, can be coupled to the tracheostomy tube and very easy by the intervention of the thumb and forefinger of one hand can be solved in the recess again from the adapter.

The Invention will be explained in more detail below with reference to the schematic drawing. It shows:

1 an embodiment of the tracheostoma tube with adapter.

This in 1 illustrated tracheostomy tube with adapter consists of a tracheostoma tube ( 1 ) which integrally or glued or welded or molded a tubular adapter approach ( 2 ) at its distal end (which may alternatively and not shown in the figure also have an n-shaped cross-section), which at its, the Tracheostomarohr ( 1 ) end a tubular (alternatively and not shown in the figure, an n-shaped cross-section having) adapter ( 3 ) wearing.

Alternatively, the adapter may ( 3 ) also directly at the distal end of the tracheostoma tube ( 1 ) are (in one piece or glued or welded or molded - not shown in the figure).

The adapter ( 3 ) in 1 indicates at its free end ( 32 ) two opposing recesses ( 4 ) in its edge.

The tracheostoma tube ( 1 ) and the adapter approach ( 2 ) consist of medically usable plastics, such as, for example, hard PVC, which are relatively rigid, but nevertheless of a certain elasticity.

The adapter ( 3 ) also consists of medically usable plastic or of flexible thermoplastic material, such as. Soft PVC.

Particularly advantageous is the tubular adapter ( 3 ) on its inside grooves or profiles ( 31 ), which form a positive and airtight connection of the adapter ( 3 ) to be coupled accessories particularly effectively, effectively and permanently produced at the same time good solubility by hand.

By the adapter according to the invention ( 3 ) with the two opposite recesses ( 4 ) are accessories, such as Trachinaze, form-fitting to the tracheostomy tube ( 1 ), wherein the accessories, such as Trachinaze, very easily by engaging the thumb and forefinger of one hand in the recesses ( 4 ) again from the adapter ( 3 ) are separable.

The Tracheostomy tube can according to the invention both an interior and an outer tube be.

All in the description, the following claims and the drawing Features can both individually and in any combination with each other invention essential be.
