AN APPARATUS FOR INJECTION ABSTRACT OF THE DISCLOSURE An apparatus for injection especially for hypodermic injection by diabetics chiefly for self- treatment and in medical practices and clinics for the hyposensibilization treatment and heparinization in connection with the preparation for operations. The apparatus comprises cm upper chamber with negative pressure which is accumulated during the manufacturing process ; it comprises further a covering lid with a central funnel for the insertion of a syringe. Said funnel is airtightly fastened to said covering lid and a cannula shaft continues spa- tially said funnel, the lower end of which has its tip extending into a suction cup, which is airtightly sealed against said upper chamber with stored under- pressure. From inside of the rim of said suction cup through a pipe socket inside of said upper chamber next to said cannula shaft expands a valve pin with a wax seal on its upper end. If the suction cup is posi- tioned on the skin, this effects by its one elasticity a lifting of said valve pin. If the wax is broken, the air enters from the suction cup to the upper chamber and the skin will be sucked into the cannula tip. -1-
