A device for use as a subcutaneous injection set is disclosed which has a soft cannula through which a selected medication can be administered to a patient, wherein the soft cannula is adapted for transcutaneous placement by an insertion needle substantially without crimping or kinking. The cannula
A device for use as a subcutaneous injection set is disclosed which has a soft cannula through which a selected medication can be administered to a patient, wherein the soft cannula is adapted for transcutaneous placement by an insertion needle substantially without crimping or kinking. The cannula is supported by and protrudes outwardly from a housing adapted to receive the selected medication. The insertion needle is initially inserted through a septum on the housing and further through the cannula to provide a rigid structure to insert the soft cannula through the patient\s skin. The insertion needle and cannula are constructed to prevent longitudinal slippage of the cannula on the needle during the insertion process, thereby preventing undesired crimping or kinking of the soft cannula. After insertion, the needle is withdrawn from the cannula and housing to permit medication delivery to the patient.
A subcutaneous injection set, comprising: housing means defining an internal chamber adapted for receiving a selected infusion fluid, said housing means further defining an outlet bore; a soft cannula mounted generally within said outlet bore and protruding outwardly from said housing, said cannula
A subcutaneous injection set, comprising: housing means defining an internal chamber adapted for receiving a selected infusion fluid, said housing means further defining an outlet bore; a soft cannula mounted generally within said outlet bore and protruding outwardly from said housing, said cannula defining a hollow lumen; an insertion needle removably received through said housing chamber and further through said cannula lumen and terminating in a point tip disposed at least slightly beyond said cannula, said insertion needle being withdrawable from said cannula and from said housing subsequent to transcutaneous placement of said cannula through the skin of a patient; and means for preventing slippage of said cannula in a direction longitudinally along said insertion needle during transcutaneous placement thereof to correspondingly prevent cannula crimping.
