Abstract

Moist heat exchange device for the breathing air is characterized in that one in a cavity, preferably cone (4), placed filter (7) by means of a locking member (1), (15), (17) against slipping out of the cavity, preferably Cone (4), is secured.

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 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 carry them over the inhaled 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 can be removed by means of a spring element, without touching the filter insert or the filter cage.

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 affect the application function negatively and only in conjunction with a plugged speaking valve or other instruments Prevent slipping out of the secretion-wetted filter.

Accordingly the invention has the object, a wet-heat exchange device with minimal loss of moisture and minimum height with simultaneous safety locking of the filter in the cone too to reach.

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 against slipping out of the filter from the cone is so built that without assembly of speaking valves, other HME, etc. through the placement of a locking part on the cone slipping out of the filter is prevented.

at Removing the locking part goes on the spring element and allows such a pulling out of the filter cartridge from the universal cone, without that the clogged filter is touched with your fingers must and the spring element is wetted with secretions.

The Locking part can by placing two wings be easily removed by turning on the cone.

task The invention is therefore a locking device for to create the filter located in the cone, so that slipping out or coughing is avoided. The object is achieved by the locking device solved with the features of claim 1. The dependent claims give advantageous embodiments of the invention again.

Further Objectives, advantages, features and applications of the The present invention will become apparent from the following description of the Embodiments with reference to the drawings.

The device according to the invention. 1 consists of a locking part ( 1 ) on the cone ( 4 ) after placement of the filter ( 7 ) with spring element ( 8th ) is plugged.

The spring element ( 8th ) is between wall cone ( 4 ) and wall locking part ( 1 ) trapped.

By the in Arretierungsteil ( 1 ) integrally molded web ( 3 ) slipping out of the filter ( 7 ) from the cone ( 4 ) prevented.

Due to the integral formation of two wings ( 2 ) on the locking part ( 1 ) can be adjusted by turning the locking part ( 1 ) Disassembly, removal of the used filter ( 7 ) as well as the installation of a new filter ( 7 ) respectively.

The 2 shows the cohesive attachment of a strand ( 9 ) on the locking part ( 1 ) with a clamping ring ( 10 ).

The clamping ring ( 10 ) is in the clamping diameter ( 11 ) over the cone ( 4 ) and thus prevents during disassembly of the locking part ( 1 ) to remove the used filter ( 7 ) and to install a new filter ( 7 ), that the locking part ( 1 ) can be moved.

In the 3 is a locking cap ( 15 ) shown as a locking part.

The locking cap ( 15 ) is connected with a strand ( 9 ) and a clamping ring ( 10 ) formed.

Through the slip-on phase ( 13 ) attaching to the cone ( 4 ) facilitated.

The design of the locking diameter ( 14 ) is chosen so that the locking diameter ( 14 ) by 1 to 2 mm smaller than the inner diameter of the cone ( 4 ). This creates a border ( 16 ), the slipping out of the filter ( 7 ) prevented.

Through a tab ( 12 ), the disassembly of the locking cap ( 15 ) facilitated.

The 4 shows a simple clamp bridge ( 17 ), through the clamp ( 18 ) with the cone ( 4 ) and with the help of a strand ( 9 ) and clamping ring ( 10 ) on the cone ( 4 ) is attached.

By forming a bracket ( 19 ) Disassembly can be easier. The coat hanger ( 19 ) also guarantees a support distance to a tightened textile. This avoids respiratory obstruction.
