    Apparatus and method for use in the removal of material from body cavities by suction. The apparatus comprises a catheter (3), a suction unit (1) and a collection container (2) disposed between the catheter and suction unit, the collection chamber (2) being provided with a filter (14). …<??>To facilitate preparation and examination of material collected in the container (2), it is connected to a source of fluid (4 or 5) for washing and/or treating material collected in the container. In accordance with the preferred method, the washing and/or treating is carried out continuously. …<??>Also disclosed is a flexible catheter for use in such apparatus or otherwise. To facilitate removal of persistently adhering material, the or each suction opening is surrounded at least in part by rigid material providing a hard edge. There is further disclosed a suction catheter having a closed end and a lateral opening. To facilitate manipulation, the closed end is asymmetrically rounded.

    (54) DEVICE FOR DRAINING CONTENTS The invention relates to medical equipment, namely, to drainage devices. A device for sucking content from body cavities is known, comprising a catheter and a vacuum pump connected to the catheter via a vacuum reservoir with filter L. However, this device does not allow obtaining diagnostic material during aspiration, since it is not possible to reliably separate the material from other components of the body cavity. The object of the invention is to provide diagnostic material during aspiration. The goal is achieved by the fact that the device is equipped with additional tanks for flushing and fixing solutions connected to a vacuum tank through distribution and control valves, while the vacuum tank is equipped with a lid with a clamping device, nozzles, bag filter and made in the form of a removable transparent plastic vessel. In addition, the catheter is equipped with a guide tube, which is assembled from several OF THE BODIES of the BODY, with the possibility of fixing in it a catheter made of a flexible material with a hardened end having radial or OCGBjbie holes. FIG. Figure 1 shows a block diagram of a device for sucking content from body cavities; in FIG. 2 and 3. - catheter, Two projections; in fig. 4 and 5, an embodiment of the catheter, two projections; in fig. 6 is a section A-A in FIG. five; in fig. 7 and 8 variant of the implementation of the catheter, two projections; in fig. 9 shows an embodiment of a catheter; in fig. 10 - guide tube, longitudinal section; in fig. 11 shows an embodiment of a guide tube; in fig. 12 and 13 section bb in fig. 11 (for two latch positions). The device contains a catheter 1 made of a flexible material with. hardened end 2 having radial or axial holes 3. The catheter 1 is connected to the vacuum pump 4 through a vacuum reservoir made in the form of a removable transparent vessel 5 made of plastic. The vacuum tank is equipped with a lid 6 with a clamping device 7, nozzles
    8-10 with a bag filter 11 connected to the nozzle. I 9.
    In addition, the device has a capacity of 12 for the washing solution and a capacity of 13 for the fixing solution. The containers 12 and 13 are connected to the vacuum tank through the corresponding control valves 14 and 15 and the common distribution valve 16. On the line connecting the vacuum pump 4 to the vessel 5, a control valve 17 is installed, connected to the nozzle 8 of the vacuum tank, to the branch pipes 9 and 10 of the same reservoir, respectively, a control valve 16 and a catheter connection line 18 are connected. Cat 5; ep 1 is provided with a guide tube assembled from several parts with the possibility of fixing a catheter in it with the aid of a clamp 20.
    The device works as follows
    A catheter 1 is introduced into the cavity of the body 21 by means of a guide tube 19 and is connected via a pipe 10 to a vacuum tank. Using a vacuum pump 4 in the vessel 5, a vacuum is created, as a result of which suction occurs through the catheter 1 of the contents of the body cavity. At the same time, the washing and fixing solutions can be supplied to the vessel 5. The volume and sequence of supply of these solutions is regulated by a control valve 16 and control valves .14 and 15,
    As a result of the washing solution in the vessel 5, the diagnostic material is separated. The spent washing solution is continuously removed from the vessel. 5 through the nozzle 8. After the washing process is completed, the tank 13 is connected to the vacuum tank with the help of the valve 16, the fixing solution starts to flow into the vessel 5 .
    At the end of the fixation process, the specimen diagnostic material is removed from vessel 5 after disassembling the vacuum tank.
    Thus, the design of the device allows to obtain diagnostic material during aspiration.
