PROBLEM TO BE SOLVED: To prevent a communicating needle from shaking when mounted at the mouth part of a syringe and to prevent the disengagement thereof from the mouth part of the syringe at the time of removing a cap. SOLUTION: This communicating needle 1 consists of a hollow needle body 2 which is formed by having a hypodermic needle juncture 21 and a pricking needle 22 respectively on the front and rear of a hub 23 and a cylindrical skirt part 3 with which this needle body 2 is successively provided. This skirt part 3 has the bore approximately equal to the outside diameter of the cylindrical part 52 of the syringe 5 shown in Fig. and is fitted slidably onto the cylindrical part 52 of the syringe 5. The needle body 2 of the communicating needle 1 is preferably protected against contamination by a cap 4. |
