Actuation to open the shut-off device® in both lines and a pump are provided, which are made of an elastic, impermeable part, which divides the interior of the pump housing into two / ei chambers, one of which with the vacuum space and the suction line in the direction of flow behind the associated shut-off devices and of which the others with the liquid reservoir and the pressure line in the direction of flow λγογ the associated shut-off organs are connected.

In a first embodiment, a cuff is arranged sealingly displaceable on the suction and pressure lines designed as rigid pipes, on the inner wall of which the associated shut-off element is attached, which is held closed by a spring acting on the cuff. The shut-off element in the suction line can hardly be opened by pressing down the cuff by pushing the cuff, whereby this cuff minimizes the cuff on the pressure line when it is shifted and thereby opens the ¥ ®nt-il in the pressure line etiias later, so that by dl® Pressure line fluid is supplied from the pump,

In another AusviiT-ungstoTm suction and pressure lines consist of soft, deformable hoses ₉ which are blocked by pressing together _f with appropriate separate compression elements for "each of the two lines vorg@seh.en"

Another feature exerts Erx'Isäung is the configuration of the pump, which as mentioned, above, of a housing there is the _s by an elastically deformable part, "B z _e in the form of a membrane or a hollow cylindrical body, is divided into two chambers" One chamber is reduced in size when it is connected to the yakuum cisr suction line and sucks the liquid to be _{supplied into the other chamber - β} Dana tjird In dl © one chamber - via the sang line - pressure

The further details of the invention are to be described with reference to the drawing, but not the invention should restrict. Point in the drawing

According to Figo 1 to 3, the device © has a suction cannula 1, the hollow cuff 2 with a suction line 3, which can be moved through © In ©, is in YerMactang? it leads to an _{outlet 4 O} Di® cuff 2 which is under vacuum, has an axially located widening 5 and two tubular © ends 6 ₅ 7d which slide sealingly over the oil © associated ends of the suction cannula® 1 and the suction line 3. A valve 8 is attached to the inner wall of the extension 5. In FIG. 1, the cuff 2 is pressed to the right by a spring 9, whereby the valve 8 lies against the opening of the suction line 3 *. The spring 9 is supported on the one hand against the cuff 2 and on the other hand against the solid wall of the housing 11 from ₉ which encloses the individual Teilgd.es device.

The cuff 2 can be moved by hand to the left against the action of the spring 9 by means of an angled lever 12 which is pivotable about the axis 13 ai housing 11 ", The arm of the angled lever 12 is located in Ringilanseh 15 der Cuff 2 on _e If you press on the arm 16 of the angle lever in the direction of the Pf®il © sf ₉ , the lever arm 14 moves the

Cuff 2 to the left.

As shown in FIGS. 1 to 3, the pressure line * ^ e has the same Parts like the parts of the suction line described above · These parts should therefore not be described again. They are denoted below by the same reference numbers with the addition a. It should be noted, however, that the Flange 15a to the left opposite the vacuum space 4 and the Flange 15 is offset. As a result, that opens up Valve 8a with a certain delay compared to the valve 8. As FIG. 3 shows, when moving the Sleeve 2 of the flange 15 against the flange 15a and moves then the cuff 2a also to the left, so that the suction line 3 and the pressure line 3a through a Angle lever 12 can open one after the other.

The device also has a device 17 acting as a pump, which is used to supply a physiological serum from a Reservoir 18 is used. This pump 17 consists of a housing with an elastic membrane 19 »which forms the housing divided into two separate chambers 20 and 21. The chamber 20 is connected to the suction line 3 via a connection 22 in connection, while the other chamber 21 through a connecting line 23 with the storage container 18 via a check valve 24 is connected. As a result, the serum from the reservoir 18 can only go to the pump and from there through the drainage opening 25 flow into the pressure line 3a.

The device works in the following manner. In the starting position according to FIG. 1, the valve 8 closes the suction line 3. Of the Pressure in the chamber 20 corresponds to the vacuum, which the membrane 19 deforms maximally upwards, whereby a dose of serum over the check valve 24 is sucked into the chamber 21

If you press the angle lever 12 in the direction of arrow f down, the cuff 2 is moved to the left, so that the valve 8 releases the opening of the suction line 3 (see FIG. 2). This causes the suction line 3 with the air pressure

Between the two test tubes there is an elastic elongated cap 54 in the form of a cylindrical hollow body which forms the movable part of the pump. The edge of the Kapp © 54 is fixed in the mounting bracket of the two test tubes 5 ^ ₉ 53. The cap 54 divides the space between the two test tubes into an outer volume 55 and an inner volume 56. The outer volume 55 has a connection 57 at the bottom which leads to a vacuum space, not shown, and a second connection for the suction line. The inner test tube 53 contains an axially arranged tubular passage 58 which is "connected" to the internal volume of the pump via a check valve 59 and via a line 61 to a bottle 60 for the liquid to be sucked in, eg serum. Furthermore, the pressure line 35 is connected to the internal volume. 56 connected by a line 62. -

The apparatus according to the second embodiment operates as follows Wise

The aspiration of the secretions and the insertion of the _ß serum are completely independent processes and can vorgenoi separated from each other at a suitable time! N © be ii. For the extraction of secretions Winkelh © b @ l 38 (FIG _e 5) is "pressed down, This opens the L © Iking pile 34 and the vacuum sucks the secretions via line 97 _9, the" volume 55 and the line 34 away..

At the beginning of the operation, the angle lever 38 and the push button 46 are in their upper position and press the Lines 34 and 35 to (see Fig. 4). The one through the vacuum in the outer volume 55 of the pump 32 generated © negative pressure ' causes the cap 56 to expand. Its volume 56 is increased and fills with serum entering through line 61 (see Figure 5).

After the pump is filled with serum, the pressure line is 35, 37, when the button 46 (see FIG. 6) is pressed, it is no longer shut off and the opening 51 in the line 34 is opened.
