FIG. 1 is a block diagram of the present invention. The kneading injector 10 kneads bone cement and injects it into a predetermined place, and the kneading part 11 is formed by a bag-shaped bag 12.
As shown in FIG. 2, the end portion 13 of the bag 12 is provided with a discharge port 15 having a ring-shaped base 14. A female screw 16 is cut on the inner surface of the ring-shaped base 14,
When the bag 12 is stored or when kneading,
A plastic threading cap 17 is fitted into the female thread 16 of the ring-shaped base 14, and the kneading injector 1
When 0 is used, the threaded cap 17 is removed from the discharge port 15, and the injector 20 is detachably attached to the ring-shaped base 14 of the discharge port 15. An inlet 18 for injecting the kneading liquid is provided at a portion of the bag 12 remote from the outlet 15.
Is formed by a film made of a material such as silicon or hard rubber in order to inject the kneading liquid into the bag 12 with an injection needle.

絞り出すようにして、注入器２０内に移し入れる。In order to use the kneading injector 10, bone cement is packed in a bag-shaped bag 12 which is a kneading section 11 in advance, and when it is used, as shown in FIG. 1
The kneading liquid is injected into the membrane of No. 8 by the injection needle 26 of the syringe 25.
After the injection of the kneading liquid, the injection needle 26 is pulled out and the film of the injection port 18 returns to the original state, but since the film is made of a material such as silicon or hard rubber, the contents of the bag 12 will not leak outside. Next, the bag 12 is thoroughly rubbed from the outside of the bag 12 by hand to thoroughly knead the bone cement and the kneading liquid. Until then, the threaded cap 17 was fitted into the ring-shaped base 14 of the outlet 15 of the bag 12, but the threaded cap 17 was removed there, and the female screw 16 of the ring-shaped base 14 of the outlet 15 was inserted into the injector. The male screw 22 of the distal end portion 21 of 20 is screwed in to integrate the bag 12 which is the kneading portion 11 and the injector 20. After that, the bone cement in the bag 12 is squeezed out and transferred into the injector 20.
