Description

Protective bone cement stirring container and method
Technical Field
The invention relates to the field of bone cement medical treatment, in particular to a protective bone cement stirring container and a method.
Background
Bone cement is a common name of bone cement, which is a medical material used for orthopedic surgery, and has such popular names because of its partial physical properties and appearance and properties after solidification, which are quite similar to those of white cement for construction and decoration.
Bone cement is often used in orthopaedic joint replacement surgery and some procedures involving the treatment of bone defects to fix implants or fill defects. Bone cement is a chemical substance, and is required to be mixed with the solution and stirred uniformly when in use. A harmful gas is generated after mixing with the solution, which is potentially harmful to the surgeon and nurse, especially if it may cause some allergic reactions. At present, bone cement is stirred in an open sterile bowl, and harmful gases overflow without protection.
