Description

The invention relates to medicine and can be used for the electrophoresis of medicinal substances in adhesions of tubular bone fractures.

The purpose of the invention is the acceleration of the processes of bone tissue regeneration due to the introduction of the medicinal substance into the regeneration zone through a catheter from a cylinder with a movable electrode.

The drawing shows the structures and main elements of the proposed device.

The device contains a hollow cylinder 1, a catheter 2, a hollow piston 3, an opening 4 in the piston, a removable piston cover 5, a plate10

the drug substance from cylinder 1 is moved into the reservoir of the reservoir 3. Enter the distal end of the catheter 2 through the trepanning hole into the bone-medullary canal to a predetermined depth, determined radiologically. Pull out the mandrel 17 through the piston 3 and fill the reservoir of the latter with an isotonic drug solution to the maximum. The piston 3 is sealed with a cap 5 connected by a wire to the negative terminal of the power supply 7. Over the area of the fracture impose an annular gasket 8 of fabric, moistened with 1 ° / o-ny solution of calcium chloride, on top of which is

strewn electrode b and power supply 7, jj plate electrode 6 connected by wire to the positive terminal of the source. Positive plate electrode 6 is made of lead, under it is a gasket 8 of fabric, hollow cylinder 1 is made of transparent material, hollow

ka 7 food. The latter is switched on and the current set is set. If there is no current, as indicated by the indication of the microammeter on the source 7, the pi-piston 3 and the removable lid 5 are made of metal. 20, by displacing the piston 3 in the cylinder 1. On the latter there is a nut 9 for establishing contact between the electrolyte of the wire fastening connecting the lid of the catheter 2 and the tissues of the bone-brain cassette 7 to the power source 7. Catenary connection.

The tera 2 and the hollow cylinder 1 are sealed. The proposed device will allow using the tip 10, the secret 11, to keep the regeneration period due to the electrically conductive ring 12 and the connecting bushing directly onto the regenerative coupling 13. The piston ring 14 is installed to seal the piston gasket 15 made of rubber. For air outlet, when the piston 3 is sealed by a cover 5, a length of 30 versts 16 is provided.

To increase the stiffness of the catheter 2 when inserted into the bone-marrow canal, there is a mandrel 17, represented by a single wire strand.
