Description

The invention relates to medicine and is used in gynecology to collect the contents of the uterine cavity by vacuum aspiration.

The purpose of the invention is to prevent the loss of individually collected aspirate during operations of early termination of pregnancy.

Figure 1 shows a device for collecting aspirate, general view;

in fig. 2 - a container without gills;

in fig. 3 - krnshka;

in fig. 4, another version;

C in fig. 5 - the same, top view.

The device for collecting the aspirate consists of a hollow transparent handle I, filled with two halves, the lower 2 and the upper 3, with fittings 4 and 5, respectively, communicating with the vacuum source and with the aspiration tip. The fitting 5 has a nozzle 6 placed inside the upper half 3 of the handle I, and forms a single channel parallel to the longitudinal axis of the handle I.

Inside the handle I, symmetrically along its longitudinal axis, there is a container 7 with an inflated removable handle 8. Spout 6 enters the hole 9 of the conical part 10 of the handle 8. Between the outer surfaces of the container 7 and the inner surfaces of the handle I, there is a space II for the passage of air, and there is also an air space 2 between the nozzle b and the hole 9. The container has a supporting exterior inlet 12. Crank 8 has a centering flange 13 with notches 14.

In the half of the lower half 2, handles I freely insert the container 7 with a removable handle 8, in which the conical part 10 is filled outwards (fig. 3) or inwards (fig. 4), after which the lower half 2, connected to the vacuum source, is tightly connected to the upper half 3, to which a rigid aspiration tube is connected

With a tip. The upper 3 and lower 2 halves form a handle I with an aspiration tip and a source of vacuum, which is fed through a fitting 4.

With the help of a handle I, an aspiration tip is inserted into the uterine cavity (not shown), a source of incisions is turned on. Aspirate through a fitting 5 through a nozzle 6 enters a container 7 through an opening 9 removable valve 8.

After the end of the vacuum-aspiration operation, an aspiration tip is inserted into the uterine cavity with the help of the handle I. The handle I is placed in a vertical position, the upper half 3 of the handle I is opened, a container 7 with a filled aspirate is removed from the lower half 2, which in turn is opened with the help of a handle 8 and emptied into a clean flat container for inspecting the contents of the uterine cavity, it is determined how well the vacuum-aspiration operation was performed, whether there is a chorion, and it is also determined, even emptying through the container with an aspirate, the total ego amount, the amount of blood loss during vacuum-aspiration operations, which fluctuates, as a rule, in the range from 30 to 80 ml. In addition, it is possible to send the contents to a laboratory for analysis.

Having released the handle I from the aspirate-filled container 7 with the nozzle 8, into which a clean container 7 is easily inserted into the nozzle 8, and the aspiration tip is quickly replaced with another, the device for collecting the aspirate is ready for a new vacuum aspiration operation, which can also be produced in the same way as the first one, which is very important in the conditions of clinics, in which, as a rule, vacuum-aspiration operations are placed on flow (that is, they have to do a large amount). Operations are performed in special centers and it is important to examine the aspirate after each patient in case it is necessary to send it for histology.

Thanks to the simple construction of the device with it (it is easy to handle both when preparing it for work, during and after work, which shortens the overall time of all vacuum-aspiration operations.

In addition, since the nozzle entering the inside of the handle, to which the aspiration tip is externally connected, enters the opening of the container, the aspirate enters directly into the container, where it is completely collected, which allows you to quickly give a quantitative and qualitative assessment of it. Thanks to the presence of the cranial aspirate, it does not flow out when tilting during vacuum-aspiration operations in the space between the container and the handle cavity, as a result, the handle is not contaminated _with bloody liquid and does not require its special treatment when changing containers.
