FIELD: medicine.

SUBSTANCE: invention relates to medical equipment. Cartridge includes a bushing having a longitudinal axis and containing a distal partition provided with a distribution hole, and a cylinder forming a chamber intended for placement of material. Cylinder has an open proximal end and a destructible distal septum at the distal end. Cylinder is configured to move in the sleeve along the longitudinal axis between a first position in which the distal partition of the cylinder is spaced from the distal partition of the sleeve, and a second position in which the sealing portion of the distal septum of the cylinder is in contact with the inner surface of the distal septum of the sleeve. Piston is intended for sealing the cylinder chamber and comprises a plate configured to move into a sealing engagement in the cylinder chamber. Bushing contains an internal piercing element, which is intended for destruction of the distal partition of the cylinder when the cylinder is moved from the first position to the second position. Sleeve comprises annular cavity around piercing element. Annular cavity is limited along the periphery with an internal bevelled surface, which is complementary to the corresponding external bevelled surface of the cylinder.

EFFECT: ease of use and tightness provision.
