In comprises a tube, having a first end adapted to receive the suppository and a second end, and a plunger disposed in the tube and moveable therein to eject the suppository from the first end by causing an action of pushing the suppository from behind.Retaining tongues (7,7’) are splayed outwards for ejection of the suppository in response to movement of the plunger in the tube, via contacting cooperation between at least one part of the plunger and at least one part of the tube.Securement means (12,13,14,17) secure the plunger in the tube at a first position in which the suppository is retained in the first end of the tube, while allowing a user to move the plunger to actuate the instrument, and to secure the plunger in the tube at a second position which is only achievable after the plunger has been moved to eject the suppository.一種插入栓劑之儀器,其包括有一管體和一活塞,該管體具有一適用於接收栓劑的第一端和第二端,且一活塞置於該管體內且可在其中移動,用以藉由從後面推動栓劑的動作將栓劑從儀器的第一端射出。用於抵擋的舌片(7,7’)向外展開突伸出栓劑,以對應管體內的活塞移動,其通過活塞至少一部分和管體至少一部分之間的接觸配合關係進行。固定手段(12,13,14,17)將管體中的活塞確保在第一位置,其中該栓劑被保持在管體的第一端,同時允許使用者移動活塞以操作儀器,以及確保管體中的活塞在第二位置,該第二位置只有在活塞已被移動而射出栓劑之後才可達到。
