Abstract

Filter for the moistening of the breath and for better adaptation to deep, irregular or oval tracheostomas, characterized in that a filter (2) with a seal (6), which is connected to the flange (3) or plaster (10), in the tracheostoma (15) is placed.

Description

The invention has the content that a filter with or without a skin, connected to a convex, oval seal on a flange or on a tracheostoma patch moistens the breath and due to the convex, oval seal better adaptation to deep, irregular or oval Tracheostomas is achieved.

State of the art

Tracheostomy is one of the oldest surgical techniques in the history of medicine. The origins of this technique date back to antiquity.

In classical tracheotomy, an artificial access to the trachea is surgically created below the larynx, typically between the 1st and 2nd or 2nd and 3rd tracheal rings. In order to maintain this artificial opening for the purpose of ventilation, a so-called tracheal cannula is used.

Medical indications, such as the need for long-term ventilation make this technique necessary today.

As an alternative to the surgical technique, minimally invasive puncture techniques have been developed within the last decades. In particular, the percutaneous dilatation tracheotomy according to Ciaglia, the dilatation tracheotomy according to Griggs and the translaryngeal tracheostomy according to Fantonie are widely used.

In the percutaneous dilatation tracheotomy according to Ciaglia, the trachea is first punctured at a suitable place with a steel cannula. To ensure that the sensitive tracheal posterior wall is not damaged, this process typically takes place under bronchoscopic monitoring.

The correct position of the cannula tip can be checked by aspirating air into an attached, liquid-filled syringe. In the correct position, a Teflon catheter over the steel cannula is inserted 1 to 2 cm distally into the trachea. After removal of the steel cannula, a J-shaped guidewire (approximately 1.3 mm in diameter) is advanced through this Teflon catheter into the trachea. Thereafter, the Teflon catheter can be removed. Instead, a tubular plastic catheter with safety stop is now pushed over the guidewire for reinforcement. About the armored guide wire now one or more successive dilators to expand the puncture opening are inserted by means of a rotating movement in the tracheal lumen. Due to the conical shape of the dilators, the tissue expands so that the lubricated tracheal cannula can be inserted over the guidewire using a special obturator.

The correct position is examined with the bronchoscope. Subsequently, the guide wire can be removed and a balloon located on the tracheostomy tube to seal the trachea filled with air.

The font DE 101 09 935.5 For example, U.S. Pat. No. 5,080,701 discloses a tracheostoma prosthesis comprising a speaking valve having a valve, an outer cannula connected to a sealing balloon surrounding it annularly and connected to a pressure balloon via an air passage extending inside the outer cannula, and having perforations provided between the sealing balloon and the speaking valve near the sealing balloon, an inner cannula having an extension offset from the perforations is located near the speaking valve, a seal sealingly disposed between the inner cannula and the outer cannula near the sealing balloon is, and a suction device which is connected to a suction duct above the speaking valve consists.

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 36 050.1 a tracheal stoma is known, which consists of a tubular tracheostomy leg, which terminates unilaterally in an integrally formed and in a first dimension (y) arched tracheal limb, wherein the tracheal limb in a direction perpendicular to the first dimension dimension (Z) A-centered to the tracheostomy leg axis (XY) is connected such that it has different lengths overhang areas and the tracheostomy leg locking means are assigned to the recording and fixation of a shield in a variably adjustable distance to the contact surface of the tracheal thigh to guarantee the trachea. In this case, the locking means in the form of introduced into the tracheostomy legs grooves or in the form of applied to the trachea thighs beads are formed.

The font DE 20 2004 007 251 U1 discloses a tracheostomy tube, comprising an inner cannula and an outer cannula, wherein the inner cannula has latching means at its distal end (s), which do not form a circular cross-section of the distal end of the inner tube, but protrude from the distal end of the inner tube and engage positively in corresponding recesses / profiles of the outer cannula, where n ≥ 3, so that prevents rotation of the inner cannula to the outer cannula becomes.

The font DE 20 2004 007 252 U1 discloses a tracheostomy tube, comprising an inner cannula and an outer cannula, wherein the inner cannula has locking means on its outer wall, which give the inner cannula an n-angular cross-section, where n ≥ 3, and which engage positively in the inner wall of the outer cannula, so that twisting of the inner cannula to the outer cannula is prevented.

From the Scriptures DE 35 23 663 A1 An endotracheal cannula (tube) is known, at one end of which a connection for a respirator and at the other end an opening for the inlet and outlet of the respiration medium is provided.

From the Scriptures DE 20 2004 013 323 U1 is a tracheostomy-placeholder, consisting of a tubular tracheostomy-leg, which is formed on one side with a molded and arched tracheal limb and one on the tracheostomy-leg molded, glued or sliding and lockable flange with a multi-part clamping sleeve for positive or cohesive connections with a receiving ring for mounting with speaking valves and artificial noses, known.

Gem. Utility model DE 20 2009 016 034.3 and 20 2010 001 611.8 is an optimal suction through an additional suction tube without inner cannula and the application of an outer cannula with Innenkanülenabdichtung known as a suction device.

Many of the described cannulas are equipped with filters, so-called HMEs, which are usually placed on the inner cannula.

In tracheostoma patches, the respective filter or HME is placed in a ring, which in turn is firmly bonded to the tracheostoma patch.

The disadvantage of the described needles with filter u. a. in that a large height of the rigid filter housing increases the distance from the tracheostoma so that a leverage effect on the placed in the tracheostoma cannula, which in turn leads to inflammation.

Another disadvantage is the placement of these filters in a rigid housing, which significantly reduces the wearing comfort. Most known filters are locked with a universal cone on a cannula, which further increases the distance to the tracheostomy. A universal application is therefore not possible.

In the DE 20 2017 003 898 U1 describes a respiratory filter for a trachestoma for inner cannulas, which, however, outside, attached to the flange of the inner cannula.

The invention is therefore an object of the invention to provide a filter that is flexible and so saturated with liquid that it collects moisture when exhaling and emits moisture to the lungs when inhaled.

The essence of the invention is that the filter with a skin, connected to a convex, oval seal on a flange or on a tracheostoma patch moistens the breath and due to the convex, oval seal better adaptation to deep, irregular or oval Tracheostomas allows.

Furthermore, a larger filtration is achieved by the placement of the spotted filter piece in the tracheostoma.

The inhaled air is also moistened more. The filter piece in the tracheostoma and the seal provide an optimal seal.

When using a plaster with ring and other structures, such. Speakers, the filter area is almost doubled.

A speaking valve filter alone can not accommodate the need for adequate respiratory humidification.

The invention will be explained in more detail on the basis of schematic sketches in construction and application.
