DE2722701A1 - Bronchography inhalation device - with contrast dust vortex chamber, antechamber and valves in mouthpiece - Google Patents

Abstract

A device for the inhalation of X-ray contrast agent dust for the purposes of bronchography consists of an air inlet tube which reaches to the bottom of a dust vortex chamber. An offtake near the bottom and one near the intake lead to a dust inhalation antechamber which is attached to a mouthpiece with inlet and outlet valves. This saves the intubation of the traches and filling of the bronchial branches with an X-ray contrast dust under irradiation control under an anaesthetic.

Description

Device for inhalation bronchography

The present invention relates to an inhalation device of powdered contrast media for the radiological representation of the bronchial space.

For the radiological representation of the bronchial space, the known methods the trachea is intubated and the bronchial branches are intubated with a Contrast medium suspension filled.

However, these methods put a lot of strain on the patient because of the intubation carried out under fluoroscopic control under general or partial anesthesia.

The object of the present invention was to provide a device for the radiological representation of the bronchial space without intubation.

The object according to the invention is achieved with a device for inhalation solved by contrast media coming from a vertebral space with air inlet tube and consists of a dust inlet tube with a mouthpiece.

The device according to the invention is characterized in that the removable air inlet pipe 1 extends to the bottom of the vortex space 2, from which one branch just above the ground and another branch just below the Exit the filler opening and jointly open into the dust inlet pipe 3 on which the mouthpiece is pushed on.

There is a special embodiment of the device according to the invention in that the end piece from an antechamber 4, at one end of which the dust inlet pipe 3 and at the other end of which the inhalation valve 5 is attached and into the valve chamber 6 protrudes, on which the exhalation valve 8 sits, and at the outlet of which the beak 9 with cover 10 is attached.

The device according to the invention is illustrated by the drawings.

Fig. 1 shows a schematic representation of the side view of Fig. 2 shows a top view of the beak 9 with the screen 10.

By introducing air into the air inlet pipe 1, this becomes The powdery X-ray contrast medium located at the bottom of the vertebral space 2 is whirled up and transported via the dust inlet pipe 3 into the antechamber 4.

The air flow is expediently through a positive pressure respirator generated, so that a cloud of dust only arises when air is inhaled. There is therefore no standing dust. There will be unnecessary friction of the dust particles avoided. The development of dust can vary according to the breathing behavior of the inhaler be adjusted.

Wind sifting already occurs in the vortex space 2, i.e. larger ones Particles sediment, smaller particles lift off. Only the smaller particles are there suitable for inhalation. Their grain size is preferably in the range from 2 to 50 Fms 3 to 20 #m.

The dust inlet pipe 3 can be connected directly to the mouthpiece be. However, a flexible hose connection between the vertebral space is also possible 2 and the antechamber 4. Both the inlet pipe 1 and the dust inlet pipe 3 are detachable to the vertebral space 2 with Load contrast agent or to be able to clean.

If necessary, i.e. when inhaling the inhaler, the dust gets through the inhalation valve 5 is sucked off, passes through the valve chamber 6 and goes through or over the beak 9 into the pharynx of the inhaler. When the inhaler exhales the exhalation valve 8 opens when the inhalation valve 5 is closed. The mouthpiece is anatomically adapted to the pharynx in the area of the beak 9. By changing the cross-section cramps in the cheek and masticatory muscles are avoided. The undressed Beak 9 prevents the dust particles from settling in the pharynx prematurely, because the wet zone of the tongue is largely covered.

The extended part of the beak 9 also exercises one more light pressure on the back of the tongue, which prevents it the inhaler can arch the back of the tongue. The breathing opening remains thus free for the dust to pass through.

The cover 10 is used to fix the mouthpiece in the mouth of the inhaler.

The device according to the invention can be inhaled by everyone poorly soluble and powdery organic Use contrast media. Suitable contrast media are all iodine-containing organic shadow-forming agents Compounds such as contrast medium acids, contrast medium acids, their salts and esters The device according to the invention can consist of all mechanical and thermal machinable materials, such as glass, steel or plastic. Appropriately enough a transparent material is used for the vortex space 2.
