SUMMARY OF THE INVENTION The present invention relates to an aspirate device for use in gynecology, in particular to collect the contents of the uterine cavity using the vacuum aspiration method.

The 4934538 Is. U.S. Pat. an aspirator for collecting fluid samples for receiving liquid samples from a patient's body cavities, comprising a hollow longitudinal handle extending from said longitudinal axis, said handle having an outer surface, a socket, and a front (proximal) or posterior (distal) end. The interior of the handle is closed by the socket as a cover. In addition, a channel is provided inside the handle to connect the inner space with the proximal or distal end. The handle is also provided with a control hole for adjusting the pressure. This control hole is connected to the outer surface by the interior and said channel. A large glass bottle is attached to the socket of the handle for the body fluid samples to be collected. A suction solution is attached to the proximal end of the handle while a vacuum foil is rigidly attached to its distal end.

Due to the uncomfortable use of the device described above in gynecology, it is not advisable to stop early pregnancy. The device is not rotatable about its longitudinal axis, since the said socket is attached to the socket of the handle, which can cause aspirate spillage during rotation and thus again the inconvenience of use. Due to its asymmetrical design, the handle with the aspiration solution cannot be rotated quickly, painlessly and evenly within the uterine cavity.

The technical solution closest to the inventive idea is a medical device for diagnostic sampling according to DE 1947123. This device comprises a suction solution connected to a hollow handle connected to the vacuum source asymmetrically. The hollow handle is provided with a control hole for pressure equalization. The handle is formed as a cylindrical collecting container for aspirate, where a filter is mounted between the front ends of this collecting vessel.

The above device has a disadvantageous drainage of the collecting vessel for aspirate testing. Before emptying, the handle must be separated from the vacuum source, the inner wall must be washed and the filter cleaned from mucus and blood clot. This takes a lot of time. Since the liquid phase of the aspirate passes through the filter to another container while the blood clot stays within the handle along with the mucus, the physician cannot make accurate statements about the amount of fluid drained and the blood loss that can be made at 30-80 mg. During vacuum suction operation, the suction solution inside the uterine cavity must be rotated evenly by means of the handle, and since the aspiration extension is eccentricly attached to the handle, this results in an uneven rotation of the handle resulting in some inconvenience during use.

The problem to be solved by the present invention is to shorten the duration of the qualitative and quantitative evaluation of the aspirate and the post-operative treatment of the device in order to reuse the device as soon as possible, and to make the use of the device more convenient.

The object is to be achieved by means of a device for collecting aspirate, which has, on its front sides, a suction solution or connectors suitable for connection of a vacuum source, in order to prevent losses of the aspirate, which is occasionally collected during the operation to interrupt the early stage of pregnancy, the handle comprises a replaceable container, which is coaxially disposed in the cavity of the handle by retaining an annular space and is formed as a hollow rotation body with a closed forehead on one side, and a lid with a central opening associated with the open face of the collecting container and having a hinged front end; has a centering flange with cutouts on its periphery, and a to a nozzle for connecting a suction solution, a lid in the cavity of the handle arranged in the cavity of the handle is connected by a central opening to the cavity of the collecting container.

The invention will be described in more detail with reference to the accompanying drawings, in conjunction with the accompanying drawings.

Figure 1 is a longitudinal sectional view of an aspirate collection device according to the invention; Figure 2 shows a collecting container without a lid, also in longitudinal section; Figure 3 is a sectional view of a collecting container cap; Figure 4 shows a sectional view of another possible embodiment of a collecting container lid; while Figure 5 shows a top view of a collecting container lid.

As shown in Figure 1, the aspirate collection device according to the invention comprises a hollow, transparent handle (1). formed by two halves of a lower (2) side and an upper (3) half provided with one (4) or (5) stump, wherein the stub (4) is provided with a vacuum source (5), ) is connected to a suction (aspiration) extension. The muzzle (5) comprises a wedge (6) disposed within the upper (3) half of the handle (1) and in fact forming a channel which is axial with the longitudinal axis of the handle (1). Inside the handle (1), a collecting container (7) is arranged symmetrically with respect to its longitudinal axis, with a removable (8) lid disposed thereon. The wand (6) penetrates into the opening of the conical portion (9) of this cover (10). A space (11) is reserved for the air flow between the outer surfaces of the collecting tank (7) and the inner surfaces of the handle (1). Similarly, there is a gap between the air (6) and the opening (9). THE

EN 205 557 Β (7) has outer (12) support projections on the closed face of the collecting container. The lid (8) has a centering flange (13) with cutouts on its outer periphery (14).

The operation of the device according to the invention is as follows:

The collecting container (7) is freely inserted into the lower cavity (2) of the handle (1) by the detachable lid (8) having a conical portion (10) extending outwardly as in Fig. 3 or inward as in Fig. 4; then the lower side (2) to which the vacuum source is connected is tightly connected to the upper (3) side to which the suction solution is rigidly connected. The upper (3) and lower (2) sides are the handle (1), which together with the suction solution and the vacuum source constitute the aspirate collecting device, wherein the vacuum is introduced through the nozzle (4).

Using the handle (1), insert the suction solution (not shown in the drawing) into the uterine cavity and activate the vacuum source. Through the (5), the aspirate passes through the pipe piece (6) or through the opening of the removable cover (9) to the collecting tank (7).

After the vacuum suction operation is completed, the suction solution is extracted from the uterine cavity using the handle (1). The handle (1) is then moved to the vertical position, the upper (3) half of the handle (1) is removed, and the lower (2) is pulled out of the aspirated (7) collecting container, which can be opened by the lid (8) and then opened. (7) empty the contents of the uterine cavity from a collecting container into a clean, flat vessel for visual inspection. In doing so, it can be determined how the vacuum suction operation was performed qualitatively, whether there is a middle fetus. Prior to emptying the collecting container filled with aspirate (7), the total amount of aspirate and the loss of blood during the vacuum suction operation are determined, and the amounts generally fluctuate between 30 and 80 ml. In addition, the aspirated contents of the uterine cavity can be transferred to a laboratory for further testing.

After removing the collecting container (7) filled with aspirate together with the lid (8), the handle (1) into which a similarly clean collecting container (7) is inserted with a new lid (8), the suction extension is also rapidly replaced by a replacement. the aspirate collecting device can be used again for another vacuum suction operation, which can be performed in the same way as the former, which is particularly important in clinical conditions where vacuum suction operations are generally performed in a conveyor belt (i.e., performed in a large number). These operations are carried out in specialized health centers and it is especially important to see the aspirate after each patient if the aspirate is to be transmitted for histological examination.

Due to its simple construction, the handling of the device according to the invention is easy during both the preparation, operation and disassembly of the device, which significantly shortens the total time of the vacuum suction operation.

In addition, after the tubular member extends into the inside of the handle, penetrates into the lid opening of the collecting container, the aspirate enters the collecting container directly, where the total volume accumulates, allowing for rapid qualitative and quantitative judgment of the aspirate. Thanks to the lid on the collecting tank, the aspirate cannot spill between the collecting tank and the handle cavity during spatial tilting and rotation during the vacuum suction operation, so that the handle is not contaminated with bloody fluid, so no special treatment is required when exchanging the collecting containers.
