Abstract

FIELD: medical engineering. SUBSTANCE: device has several sealed reservoirs connected in parallel to compressor device and discharge system. Reservoirs width is greater than their height to enable long-term support of physical state of a substance located in the reservoir. The discharge system is manufactured as a set of tubes of different diameters provided with clamps and reverse valves. EFFECT: uniform, controlled and simultaneous introduction of substances varying in physical state into organism cavities. 1 dwg

Description

 The invention relates to medicine and is intended for the introduction of liquid, gaseous, foamy media in the body cavity.

 Known Bobrov apparatus [1], intended for introduction into the cavity of a liquid or air, which is a high glass sealed vessel connected to two tubes; when air is injected into the vessel through the first tube, liquid or air in the vessel enters the cavity through the second tube under pressure.

 However, the known device does not allow you to accurately control the pressure and speed of filling the cavity, as well as to introduce foamy media into it.

 For the introduction into the cavity of an organism, a microcompressor is also used [2], which does not provide the introduction of aerosols and foam-like agents.

 The closest to the claimed device prototype is a device for intracavitary administration of substances [3], which is equipped with an electric motor with a shaft, while the container for the substance is sealed from elastic material, equipped with a flexible hose with a check valve for supplying the substance and mounted on the shaft with the possibility of winding on him, however, this device also does not provide a dosed speed and pressure of the introduction of substances; the substance enters the cavity in portions, and the number of servings depends on the rotation and size of the shaft.

 In addition, these known devices do not provide for the simultaneous administration of substances with different physical conditions.

 The aim of the invention is the provision of uniform, dosed and simultaneous administration of substances of various physical conditions.

 The infusion-insufflation device comprises a compressor (1) connected to several sealed containers (4), which, in turn, are connected to a discharge system (6); the width of the containers (4) exceeds their height, and the outlet system (6) is made in the form of tubes (7) of different diameters, equipped with clamps (8) and check valves (9).

 The device operates as follows.

 The containers (4) are filled with substances intended for administration (for example, liquid, air and (or) foamy). The compressor (1) through the fittings (2) with the help of hoses (3) is connected to the containers (4). Tanks (4) are connected with hoses (5) to a discharge system (6). In the idle position, the clamps (8) are in the closed state. After turning on the compressor (1) and opening one of the clamps (8), the substance from the corresponding container (4) enters the discharge system (7) and then to the object. The change in the speed and pressure of substances depending on the capacity and pressure in the body cavity is made by the air supply regulator (10). The choice of the substance to be introduced from the corresponding container (4) is carried out by opening the corresponding clamp (8). The opening of several clamps allows the simultaneous introduction of several substances.

 The device is a compressor (1) having several fittings (2) connected in parallel using hoses (3) with several sealed containers (4), made in such a way that their width exceeds the height for long-term maintenance of the physical condition of the substance in the tank ( e.g. foam). A drainage system (6) is connected in parallel with the containers with hoses (5), which is a tube of different diameters (7), equipped with clamps (8) and check valves (9) corresponding to the tube size.

 Using this device was carried out, for example, the introduction of substances into the intestine during x-ray examinations. In this case, the smallest diameter of the tube of the exhaust system was used to introduce air, the middle one was suspended, and the largest one was a foamy substance. This ensured uniform, dosed and simultaneous administration of substances of various physical conditions into the body cavity.
