Abstract

Moist heat exchange device for the respiratory air, characterized in that a filter (1) with concavity (5) of the surfaces, mounted in a central opening (3) with a cone (6) through the insertion height (4), the airway (14 ) keeps clear.

Description

The invention is a wet heat exchange device for placement on tracheal cannulas or other tracheal tubes with universal attachment, preferably for infants.

After a larynx removal increased respiratory problems may occur because due to the broken connection between the nose and lungs eliminates the functions of the nose. The breathing air is no longer filtered, warmed and moistened. This leads to irritation of the bronchial mucosa, excessive secretion production and thereby to increased cough.

In addition to heating, humidifying and filtering respiratory air, natural nasal breathing also provides respiratory resistance, which is important for oxygenation in the blood. The lower resistance after laryngeal removal lowers the oxygen concentration in the blood. For the person concerned, this shows in the form of fatigue, depression and diminished performance.

The humid heat exchangers are intended for patients with spontaneous breathing and are attached to the universal cone of the tracheostomy tube or a tube and serve for pulmonary rehabilitation.

The moisture-heat exchangers remove moisture and heat from the exhaled air of the patient and return them to the patient via the inhaled air. This filters the respiratory air, moisturizes it and prevents particles from entering the respiratory tract of the patient.

There are known a number of devices that act as a wet-heat exchanger and as a filter for particles.

In the PCT WO 95/17138 a tracheostomy filter with a spring valve is described. The application with a universal cone is not possible.

in the U.S. Patent 5,738,095 a same device will be described.

The U.S. Patent 5,259,378 offers a filter that is also incompatible with the universal cone of a tracheostomy tube.

The U.S. Patent 4,971,054 offers a filter that can be connected to a universal cone, but redirects air flow based on shower protection.

In the PCT WO 98/33543 a filter with adhesive film is described.

A connection with the universal cone of a tracheostomy tube is not possible.

In the DE 203 02 580.6 a moist heat exchanger for breathing air is characterized in that in a housing an impregnated with active substance, permeable, elastic, slotted active substance insert and an unslotted active ingredient insert with a slotted and unslotted, air-permeable, elastic filter insert is deposited, the inhaled air with active ingredients and moisture accumulates and strips mucus from an inserted in the slotted lid area suction when pulling out.

In the DE 20 2004 011 290.6 a moist heat exchange device for breathing air is characterized in that in a cage-like housing with a molded by a flexible hinge strand, lockable with the housing lid a wetted with moisture absorbing agents foam filter is placed and by a receiving socket on the housing locking with a universal cone possible is.

In the DE 20 2004 008 959.9 is a wet-heat exchange device for the breathing air characterized in that in a designed as a cassette lattice housing with lid a profiled foam blank is deposited for the combination with a speaking valve and the lid is mounted or dismounted by means of a clip on the speaking valve.

Known is a wet-heat exchange device for toddlers, which can be plugged in addition to the cannula cone and thus extends the length to the detriment of the patient.

The utility model no. 203 03 014.1 includes that in a grid housing a foam blanking ring is deposited and the housing with the aid of a half-round groove on the speaking valve can be mounted or dismounted.

The lid is made of a soft material slotted or not slotted with the housing jammed.

The utility model no. 20 2008 002 152.9 shows a filter insert placed in a cavity, which can be removed by means of a spring element, without touching the filter insert or the filter cage.

The disadvantage is that a disability of the speech membrane can occur and that the spring element is wetted with secretions.

The GB No. 20 2008 013 268.1 . 20 2008 011 544.2 . 20 2008 007 056.2 and 20 2008 002 152.9 Although all have a hard cone, the inside equipped with a filter, but as a hard object on the neck has a negative effect.

In general, it has been found that the known possibilities for moist heat exchange for breathing air, especially for toddlers, by a too large length and the material hardness of the cone affect the application function negative and slipping out only in conjunction with an attached speaking valve or other instruments prevent the secretion wetted filter.

Accordingly, the invention has for its object to achieve a moisture-heat exchange device with minimal loss of moisture and minimum height with optimum security and simultaneous security locking of the filter in the cone.

This object is achieved in that around the universal cone, which is connected to the tracheal cannula, a filter is deposited, which can be disposed of by a special tab without touching the verschmastenten filter cartridge.

As a result, the height is only slightly increased in the already existing distance range of the universal cone.

The freedom of movement of the patient is improved, pressure points, kinking and twisting are avoided.

To reduce the water loss mg / liter of the inhaled air and the associated risk of lung damage, a wetted with a moisture-binding agent, foam-like, elastic, open-cell foam is placed as a moisture-heat exchanger to the cone.

The sampling device is locked on the foam and allows easy installation and removal of the filter cartridge.

The device against slipping out of the filter from the cone is constructed with an adhesive film so that slipping out of the filter is prevented without mounting of speaking valves, other HME, etc. by placing a locking member on the cone.

The object of the invention is to develop a filter for the cone, which only slightly exceeds the height of the cone and allows optimal carrying by the softness of the support material.

The use of an adhesive film provides easy and secure locking around the cone on the tracheal cannula flange as well as easy removal of the filter after use.

Due to the special construction, no housing with an inner cone is required. There are no adjustment problems for cones from different manufacturers.

Each cone can be easily equipped with the new filter device.

The object is achieved by the filter having the features of claim 1. The subclaims reflect advantageous embodiments of the invention.

Other objects, advantages, features and applications of the present invention will become apparent from the following description of the embodiments with reference to the drawings.

All described and / or illustrated features, alone or in any meaningful combination, constitute the subject matter of the present invention, also independent of their summary in the claims or their dependency.
