Definitions

• the invention relates to a suction catheter with at least one lumen passing through from the proximal end to the distal end of the suction catheter for the endotracheal and endobronchial suctioning of the mouth, nose, throat and bronchial space with and without a ventilation tube, in which the suction catheter is made of a sterile flexible Case is surrounded by transparent plastic.
• Suction catheters for suctioning the mouth, nose, throat, bronchial area are available in various configurations, for example from DE-OS 2540 536, DE-OS 1491 652, US-PS 4300 550, DE-AS 2364 119, DE-PS 3608 943 and DE-PS 3812 754 and others known.
• the endotracheal and endobronchial suctioning of the mouth, nose, throat and bronchial area can be carried out with and without a ventilation tube, see for example DE-OS 2308 400.

This is only the case if any suitable suction catheter of different sizes for children and adults, single-lumen or multi-lumen with different curved tips for right and left guidance in the lungs can be used without problems.
• the search for sterile gloves, putting them on, and later throwing them away should be avoided, since during this time the gloves have to be removed, for example, the personnel must move away from a respirator or two people must be present at the same time.
• the suction catheter is provided with a flexible and collapsible sheath which is itself sterile and in which the suction catheter, at least the area which can be inserted into a patient for suction, is accommodated in a sterile manner.
• the suction catheter with the sheath is then accommodated in a further packaging, from which it is removed for the purpose of use.

• the sheath is provided to firmly connect the sheath to the suction catheter in the region of the proximal end.
• This firm bond can be done by gluing the cover with an adhesive or by welding the Cover on the outside of the suction catheter. It is also possible to clamp the sheath in the area of the proximal end, for example in the area of an attached funnel, on the suction catheter or to clamp the sheath on the suction catheter by means of an additional clamping ring.

• This suction catheter which can be handled sterile according to the invention, also represents an inexpensive and economical solution to the problem of sterile handling of suction catheters when they are used.
• the sheath can be designed as a tube or can also be formed from one or two foils with longitudinal weld seams. Such plastics are preferably used for the shell, which are under ' supply can be welded by heat.

This can be done, for example, by gluing or welding to the suction catheter, see FIG. 3, or by clamping onto it, for example by means of an additional clamping ring, or, for example, by clamping with the

• the tear-off tab 5a is formed between the row of perforations 5 and the end 4a of the sheath 4, the shear tab 4a being opened when the latter is pulled off in the region of the distal end of the suction catheter.
• the tear-off tab 5a is formed on the sheath 4 at such a distance from the distal end la of the suction catheter 1 that even after it has been torn off there is sufficient protrusion of the open distal end 4c of the sheath over the distal end la of the suction catheter as protection.
• the suction catheter shown in Figure 1 with sterile sheath 4 can thus be taken out of a general package for use, the person handling must take -not sterile gloves, since the sleeve 4 a sufficient ⁇ sterile protection for the fact that are available suction catheter 1 also offers during handling and insertion and remaining in the patient.
