The invention relates to medical technology, namely to the category for the introduction of drugs into the lumen of a hollow organ.

The purpose of the invention is to maintain sterility in animal experiments.

FIG. 1 shows a device for puncture, general view; in fig. 2 - the same section; in fig. 3 - a whisk with a nozzle, a slit.

The device contains a puncture needle 1 with pavilion 2, the needle is located in a guide tube 3 made of elastic material connected by an expanded end 4 by means of a corrugated bellows 5 with pavilion 2, and the opposite end of tube 3 has a threaded connection 6 with a nozzle 7, equipped with a rim 8, made of an elastic material, and provided with a limiter 9 of the translational movement of the needle 1. Provision is made for a device in which the inlet of Pavilion 2 is closed by a diaphragm 10 made of el stichny material.

The device is operated as follows.

If necessary, perform multiple, time-separated instillations of the drug into the lumen of a hollow organ, for example, into a blood vessel, to the target vessel are accessed quickly. Then the nozzle 7 is fastened on the vessel 11, for which the edges of the rim 8 are led around the vessel 11 and interconnected with grooves. It is possible to glue the attachment of the nozzle 7 to the station, the cavity of the hollow organ II, for which the veins

The chuck 8 is applied with medical glue and the nozzle 7 is applied with a rim to the wall of the hollow organ 11. Then air is forced out of the needle 1, for which piercing the diaphragm 10 with an injection needle pumps physiological saline into the lumen of the needle 1. The device is guided through a previously prepared hole, screwed to the nozzle 7, mounted on the wall of the hollow organ 11. They injure the surgical wound.

The device is ready for operation. Attached to the syringe with the drug needle pierce the diaphragm 10 and press Pavilion 2 to the extended end 4 of the tube 3, while the needle I passes through the wall of the hollow organ 11 into its lumen, and the stopper 9 prevents the needle from deepening into the lumen of the body 11. Pushing Pore-HjeHb syringe injected the drug into the hollow organ, since the puncture hole has a small diameter, it closes thanks to

the elasticity of tissues of the wall of the organ 11. To remove it, unscrew the tube 3 from the nozzle 7, which remains on the wall of the hollow organ, and the device itself is pulled out of the tissues.

The proposed device has the ability to install the device under the skin, which will reduce the risk of developing infectious complications, will allow using the device after a long period of time after moving it in the body and resorting to its use during

arbitrarily long time. Such an arrangement of the device will eliminate the possibility of damage to the device by the animal itself.
