Description

Postoperative drainage device

The utility model relates to the field of medicine and can be used to remove fluids and biological waste from the surgical field, inject fluids and / or drugs into the surgical area, and it can also be used as a dropper.

Known suction device 1, comprising a vacuum pump with an electric motor, a power circuit and a micro switch, a receiving tank and an automatic voltage regulator. The device is additionally equipped with a check valve installed between the vacuum pump and the receiving tank. The automatic rarefaction regulator is made in the form of a float chamber and a microswitch and two communicating vessels, one of which is fixed and connected to the float chamber, and the other is movable. The device is designed to perform long-term aspiration from closed cavities with continuously adjustable vacuum and automatic emergency depressurization of the system.

The disadvantages of the suction device 1, taken as a prototype, include the complexity of its design, the small amount of vacuum (vacuum) that can be obtained using this device, the low speed of the vacuum and, therefore, the low pumping speed of the liquid.

The task to which the creation of the proposed device is directed is to expand the technological capabilities of the device for postoperative drainage, ensure ease of use, and also increase the level of vacuum created in the device.

The problem is solved in that the device for postoperative drainage containing a collection tank, a first vacuum tank, a valve, further includes a second vacuum tank, carrying 61 Ml / 00

a mounting bracket with a sleeve, into which the first tube is inserted with a bearing bracket attached to it, connected to a contact angle with a 1-prism prism and provided with a screw device, the carrier tube is mounted on the carrier tube fixed in the carrier bracket and the first bracket inserted into it, on which the first a plate for mounting on it a first rarefaction tank and a collection tank, the upper horses of the carrier pipe is connected to a collet, into which a second pipe is inserted with a second body and a second bracket connected to it, in which fixed second plate for placing thereon a second vacuum container, wherein the first and second vacuum containers are connected to manifold vacuum through the valve, the second collection container and the vacuum tank are connected by a first line and the second line connects the collecting container and the region of the operational field of the patient.

In FIG. 1 shows a diagram of a device for postoperative drainage.

The bearing bracket 1 comprises a sleeve 2 with a thread and a first pipe 3 fixed to it, to which a bearing corner 4 is attached with a screw device 5 fixed thereon, a stop angle 6 and a mounting prism.

The carrier pipe 8 is screwed into the sleeve 2, on which the first body 9 is mounted with the possibility of fixation on the carrier tube 8. On the first body 9, a first bracket 10 is fastened along which the lower clamp 11 is movably fixed. The first plate 12 is attached to the lower clamp 11 with racks 13 with openings into which the rope 14 is threaded to fasten the first rarefaction tank 15 and the collection tank 21.

A collet 16 is fixed on the supporting pipe 8, through which the pipe 17 passes with the second body 26 put on it to connect the upper clamp 23 with the second arm 24 for the second vacuum tank 25 located on the second plate 27.

The second pipe 17 has the ability to immerse through the collet 16 into the supporting pipe 8 and fixation in any position.

The first and second rarefaction tanks 15, 25 are interconnected by a vacuum line 18 through the valve 19.

The second rarefaction tank 25 is connected via the first line 20 to the collection tank 21, which in turn is connected to the suction site of biological substances or liquids by the second line 22 (region of the patient’s surgical field).

As the vacuum capacity in the proposed device, you can use the dropper system.

A device (apparatus) for postoperative drainage works as follows.

First, a certain level of rarefaction is established in the dilution tanks 15, 25. Then, 11 liquids and biological waste are directly removed from the field of the operative field to the collection tank 21, or liquids and drugs are introduced into the surgical zone or the patient.

Setting the required level of rarefaction (in milliliters) is done by adjusting the distance between the first and second vacuum tanks 15, 25 in height.

The device allows to obtain the value of rarefaction in the second rarefaction tank 25 to 1200 mbar. To do this, perform the following operations. Having opened a tight cover, a certain amount of liquid (for example, water) is poured into the second vacuum tank 25 and tightly closed. The cover of the collection tank 21 by line 20 is connected to the cover of the second vacuum tank 25, and line 22 is connected to the suction point and sealed. If you open the valve 19, then the liquid from the second vacuum tank 25 will begin to flow into the first vacuum tank 15, and under the cover of the second vacuum tank 25 there is a vacuum process that creates a vacuum through the line 20 in the collection tank 21 and, therefore.

In line 22, going to the patient. The magnitude of the vacuum (vacuum) is proportional to the height distance between the vacuum tanks 15, 25, and the speed of the vacuum is determined by the degree of opening of the passage section of the valve 19. The vacuum tanks 15, 25 and collection 21 are attached to the posts 13 by the rope 14.

The proposed device for postoperative drainage can be installed on the patient’s bed, on the operating table, on a mobile device for moving between beds and wards, as well as on an ambulance stretcher.

The device using the supporting bracket is mounted on an element having a profile of a circle, polyhedron, corner or plate.

A significant advantage of the proposed device is the possibility of obtaining a vacuum without the use of an electric pump, i.e., the absence of an electric motor in its design, which significantly reduces the noise level during operation of the device, and also reduces its cost.

The device can be easily moved (moved or rolled over) to any place, both assembled and disassembled into nodes or parts, which is important in order to ensure the disinfection of the device for postoperative drainage.
