Abstract:
Disclosed is a two-liquid mixing type injector wherein a torque transmission means which provides torque to a rotary mixer from a drive unit is housed at an intermediate position (7a) of a through area (7) in a head unit (1), where said torque transmission means is a magnetic coupling (25) formed by an outer member (24) equipped to the end part of a drive shaft (6) and an inner member (23) equipped to the end part of a mixing rotor (5). A covered cylindrical partition (26) is integrally formed between the inner member (23) and the outer member (24) on the base of the intermediate position (7a). Channels (9, 9a) which supply liquid medicine inside the rotary mixer (3) are formed on the lower surface of the head unit (1) and provided with outlets (10, 10a) formed as openings thereupon, and said channels are formed continuously with receiving openings (8, 8a) of liquid medicine supply means (2, 2a) which are formed so as to provide openings from the head unit (1). Only one of the channels (9) is formed so as to connect to a lower position (7b) of the through area (7), and as the outlet (10) of the one channel (9) is the lower opening part of the lower position (7b), liquid medicine can be completely prevented from entering in the direction of the drive unit (4) without provision of sealing material.
