Embodiment Construction

[0022] A mixer according to the invention is indicated with reference number 10 .

[0023] Said mixer comprises a cylindrical housing 12 extending along axis X and delimiting inside it a mixing chamber 20 and a further open chamber 40 adjacent to the preceding chamber 20, And the chamber 40 shares a common wall 30 with the preceding chamber 20 .

[0024] The mixing chamber 20 is open towards the outside at the respective end of the mixer 10 and has on its outer surface a thread 32 onto which the cover 14 can be screwed to close said chamber, forming one of the walls of said chamber. (see figure 2 ). Once the components to be mixed have been placed in the chamber 20, the cap 14 is applied and closed. The cover 14 is tapered in shape and has at its apex a luer opening 16 which is closed by a luer cap 18 .

[0025] The closure element 50 can be inserted and snapped into the chamber 40 (see image 3 and Figure 4 ). The closure element comprises a circular base 52 and a ho...

Abstract

A mixer (10) for obtaining bone cement for medical use, the mixer (10) comprising a mixing chamber (20) in which at least two groups for forming the bone cement are carried out The mixer includes means for generating and transmitting vibrations to the mixing chamber (20) and a luer (18) attachment through which the bone cement can be expelled.

Description

technical field [0001] The invention relates to a bone cement mixer. Background technique [0002] In surgery, bone cement is often used for bone reconstruction. [0003] Bone cement is usually prepared from two components, one liquid (monomer) and the other powder (polymer), which are kept separate from each other until they are mixed, where they bond together. Mixing occurs as workers pour the liquid components into a container with the powder to form a cement-like mixture. [0004] Preferably, the two components are mixed in a closed vessel to prevent the diffusion of water vapor. These containers are usually provided with a mixing member, usually a piston or a spatula which can be manually actuated. Then, the bone cement is transferred and injected onto the bone via a syringe. [0005] Surgeons tend to seek thicker cements because they are easier to apply and less likely to leak into the body. However, having a higher consistency requires more effort in mixing and ...
