(54) PROBE FOR BLOCKING VESSELS

one

The invention relates to medical technology.

A probe for blocking vessels is known, which comprises an inner tube, an outer tube with inflatable balloons, connected by a common air duct and a hole in the side wall 1.

However, this device cannot be used for long-term collection of lymph from the venous angle with preservation of blood flow through the main veins of the neck due to the anatomical structural features of the latter. Meanwhile, the need to collect lymph for the study and detoxification of the body in various pathological conditions requires a probe design that can allow these manipulations to be carried out without prompt drainage of the thoracic lymphatic duct.

The purpose of the invention is the provision of a long lymph gabor from the venous angle with preservation of blood flow along the trunk. The neck veins.

The goal is achieved by the fact that in the probe the outer tube is designed as a tee, inflatable balloons are fixed at the ends of the outer tube.

the tubes have a toroid shape, and the inner tube is connected to the edges of the hole in the wall of the outer tube.

The probe includes a housing 1, a dense-elastic consistency, an outer tube 2 in the form of a tee, an elastic consistency, with blown balloons 3 of toroidal shape at the ends, common air ducts 4 connecting the system of the cylinders, an opening 5 in the side wall of the tube, to which

The probe works as follows.

The probe is inserted into the left venous angle by puncture of the inner belt or connected veins. Then by the diversion tube b, the tube 2 is advanced beyond the limits of the housing 1, through the air ducts 4

inflate balloons 3 toroidal form we. In this case, the vessels of the left-venous angle are blocked while blood circulation through the tube 2 is maintained, and the lymph enters the cavity of the outer wall of tube 2 and the vessel wall, which outflows through the aperture of the discharge tube 6. After the end of the manipulation, the balloons are lowered 3, n by pulling on the discharge tube b, the tube 2 is inserted into the housing 1 and the probe is removed.

The use of the proposed probe allows the collection of lymph during a blockage of blood vessels without disturbing the blood flow in the latter, and eliminates prompt drainage of the thoracic lymphatic flow.
