Abstract

Moist heat exchange device for the breathing air is characterized in that one in a cavity placed filter insert (3) by means of a cohesive on the filter insert attached spring foil (2) can be removed.

Description

The Invention is a wet-heat exchange device for Place on tracheostomy tubes or other tracheal tubes with universal attachment, preferably for toddlers.

To A laryngeal removal can increase respiratory problems occur because of the broken connection between Nose and lungs eliminate the functions of the nose. The breathing air is no longer filtered, warmed and moistened. This leads to to irritation of the bronchial mucosa, excessive Secretion production and thus to increased cough.

The natural nasal breathing offers besides warming, Moistening and filtering the breathing air also a breathing resistance, which is important for oxygenation in the blood. The lower resistance after laryngeal removal leaves the oxygen concentration in the blood drops. For the person concerned it shows in the form of fatigue, depression and reduced efficiency.

The Moist heat exchangers are for patients with provided spontaneous breathing and are applied to the universal cone of the Tracheal cannula or a tube attached and serve for pulmonary rehabilitation.

The Moist heat exchangers extract the exhaled air of the Patients the moisture and heat and lead These over the inhalation air to the patient again.

Thereby the breathing air is filtered, moistened and the penetration of Particles in the respiratory tract of the patient prevented.

It is a series of devices known as wet-heat exchangers and act 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 can not.

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 exchanger for Infants, in addition to the cannula cone can be plugged and thus the length to the detriment extended for 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 mounted or dismounted using a semicircular groove on the speaking valve can be.

Of the Lid is slotted from a soft material or uncut jammed with the housing.

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

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

in the Generally, it has been shown that the known possibilities for humid heat exchange for breathing air, especially for toddlers, too large a length negatively affect the application function.

Accordingly the invention has the object, a wet-heat exchange device with minimal loss of moisture and minimum height to achieve simultaneous security lock.

These Task is solved by the fact that in the universal cone, the connected to the tracheostomy tube, a filter cartridge is deposited by a special removal device without Contact the contaminated filter cartridge can be disposed of.

Thereby The height is only in the existing distance range minimal reach of the universal cone.

The Freedom of movement of the patient is improved, bruising, kinking and twisting are avoided.

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

The Removal device is locked in the foam and allows the uncomplicated installation and removal of the filter element.

The Device is constructed so that the assembly of speaking valves, HME, etc. with a universal cone pushes a spring element down, the between universal cone, outer wall of the tracheostomy tube and the cone of the speaking valve in the existing space between placed on both cones.

at Removal of the respective assembly element or speaking valve goes on the spring element and thus allows a withdrawal of the filter cartridge from the universal cone, without the verschleimte Filter with your fingers must be touched and the spring element is wetted with secretion.

The Invention will be closer through the accompanying drawings explains:

It demonstrate:

1 : a wet-heat exchanger with spring foil

2 : a wet heat exchange device with component part.

The device according to the invention. 1 has a filter cartridge ( 3 ), in a universal cone ( 1 ).

At the edge of the filter insert is a spring foil ( 2 ) glued.

The cone ( 1 ) is connected to the cannula flange ( 4 ) connected cohesively.

The cannula flange ( 4 ) is with the tracheostomy tube ( 5 ) connected cohesively.

The spring foil ( 2 ) is attached to the filter cartridge ( 3 ) connected cohesively outside.

Due to the design of the spring foil ( 2 ) as a strip, the strip protrudes by at least a three-quarter length of the universal cone ( 1 ) longer than the filter element ( 3 ), from the universal cone ( 1 ) out.

When fitting the universal cone ( 1 ) with an assembly part ( 6 ) acc. 2 is the spring foil ( 2 ) between the two cones ( 7 ).

Is the component part ( 6 ) from the universal cone ( 1 ), the spring foil ( 2 ) at an angle ( 8th ) on.

By touching the spring foil ( 2 ) and pulling out the filter cartridge ( 3 ) can be used without secretion contact the filter cartridge ( 3 ) are removed.
