SYRINGE NEEDLE REMOVING DEVICE FOR DENTAL CARTRIDGE TYPE SYRINGES

摘要

A syringe needle removing device for dental cartridge type syringes, comprising a chuck device (22) installed in a housing (11) and having a chuck dog (26) for gripping the needle base (25') of a syringe needle (25) attached to a cartridge holder (24) for a syringe (23), a device for opening/closing the chuck dog, a syringe needle reception vessel (14) rotatably supporting the housing (11), and a device (50, 55, 56) for rotating the housing with respect to the vessel, wherein the rotation of the housing with respect to the vessel rotates the chuck device together with the housing with respect to the syringe needle, thereby removing the syringe needle from the syringe. This arrangement makes it unnecessary to provide a rotation power transmission device for rotating the chuck device with respect to the syringe needle.
