Abstract

The invention relates to medical equipment, in particular to devices for removing pathological contents from cavities. The device has an elastic drainage tube with an external sleeve for fixing it in the wall of the cavity, a semi-rigid container in the cavity of which there is a single-acting flap valve, and a neck on which a suction device (pear) with two single-acting valves is fixed, a connecting pipe passes through the pear cavity. The device can actively remove pathological contents from cavities having polar pressures, creating a negative pressure in the container using a suction device (pear). 5-yl. j

Description

The invention relates to medical equipment, in particular to instruments for removing pathological contents from cavities.

The aim of the invention is to eliminate these drawbacks. .

Figure 1 shows a General view of the device Assembly; Fig. 2 - drain pipe with a sleeve for fixing it; in Fig.3 - the wall of the cavity in which the drainage tube is fixed using a fixing sleeve; figure 4 - tee device; figure 5 - suction device (bulb) with two valves.

The device for active drainage of cavities (Fig. 1) consists of a drainage tube .1, on the free end of which there is an opening 3, an elastic tube 2 is placed on top of it, its ends 2, there are two rows of longitudinal sections 3-5 not reaching the edge . One end of the sleeve along the edge is fixed to the free end of the drain

the tube so that the opening 3 is open, its other end has a small longitudinal section of a wedge-shaped shape due to which it can be freely shifted and fixed using the ring 15, which is worn on top. Given the different wall thicknesses of the cavity, there may be 3 and 4 rows of longitudinal sections on the sleeve. The second end of the drainage tube 1 is connected to a tee 6 connected to a connecting pipe 7, which passes through the suction device (bulb) 10 into the container 8 and is fixed in its neck, at its end there is a one-way flap valve 9. Container 8 nen-from polymer semi-rigid; material, in order to be able to create negative pressure in it, has a neck on which a suction-: suction bulb 10 is attached with a one-way valve 11 (Fig. 5). At the bottom of the container there is an outlet nozzle 13 closed by a lid (Fig. 1).

The suction bulb 10 is made of elastic material and is filled with a porous material 4, for example foam rubber, has an outlet neck with a sleeve closed by an exhaust valve 12. A connecting tube 7 passes through the neck and the cavity of the bulb, (Fig. 5). Thanks to such a device, it will be possible to create negative pressure in the container,

The free end of the tee 6 is closed by a plug 5 and serves to introduce drugs into the drainage cavity, the connecting tube 7 at this time is closed by the clamp 14.

The device operates as follows.

The entire device is factory sterilized and packaged in a sealed bag.

After treating the patient’s skin with an antiseptic, an incision is made with a scalpel 5-6 mm long, then the wall is punctured, the stylet is removed, the device is removed from the bag (hands with sterile gloves), the drainage tube 1 is disconnected from tee 6 and inserted into the trocar’s end with the fixing sleeve 2. The trocar tube is removed, with one hand fixing the sleeve at the ccb, with the other - the drainage tube 1 is pulled so that in the places of longitudinal cuts on the sleeve two folds are formed, which will be fixed drainage in th e stenhe cavity (fig.Z). A locking ring 15 is tensioned so that the folds do not straighten onto the free end of the sleeve 2. For better sealing of the cavity, for example, the pleural cavity, a sealing gasket is placed between the skin and the fold of the fixing sleeve 2. The free end of the drainage tube 1 is connected to the tee 6, the second end of the tee is connected to the connecting tube 7. The container 8 is not fastened to the body of the patient or to the bed using braid not shown in the figures. After barely removing the clamp 14, the pathological contents of the cavity under some pressure flow through the tubes into the container 8. when the pressure in the cavity in the container is balanced and the contents into it

does not enter, then air is pumped out of its cavity by means of a suction device (pear) 10, periodically compressing it. Semi-rigid container design and

the system of single-acting valves 1T, 12, allows creating a negative pressure in its cavity sufficient to evacuate pathological contents from the human body. Petal valve 9

allows the use of this device to drain a cavity with a negative pressure, for example, pleural.

The contents of the container are removed through the drain pipe 13 after removing the lid.

After a complete evacuation from the cavity of the pathological contents, the drainage tube 1 is removed. To do this, remove the retaining ring 15 from the fixing sleeve 2 and fix the drainage tube 1 with one hand, pulling the fixing sleeve onto one another with one hand, the folds are straightened, after which it is removed together with the drainage tube. The wound is sealed. The device is being disposed of.

The use of a device for active drainage of cavities will make it possible to activate the patient early, to prevent additional infection of the drained cavity, and to reduce the treatment time for such

sick.
