Novel bone cement stirring device with performance detection function

Abstract

The novel bone cement stirring device with the performance detection function comprises a stirring box body and a base, the stirring box body is fixedly arranged above the base, a driving motor is fixedly installed at the top end of the stirring box body, and an output shaft of the driving motor is fixedly connected with a stirring shaft; a stirring rod is arranged at the end, located in the stirring box body, of the stirring shaft, an air suction box, a water storage box and a detection box are arranged at the positions, located at the left end and the right end of the stirring box body, of the upper end of the base correspondingly, a cavity is formed in the base, and a transmission mechanism connected with the stirring box body, the air suction box, the water storage box and the detection box is arranged in the cavity. According to the device, the flowing environment of body fluid in a human body can be simulated, the liquid collapse resistance of bone cement can be accurately detected, spraying washing and blow-drying of the stirring box body can be realized, and the efficiency of bone cement performance detection is improved.

Description

technical field [0001] The invention relates to the technical field of medical appliances, in particular to a novel bone cement stirring device with a performance detection function. Background technique [0002] Bone cement is a common name for bone cement, which belongs to a kind of medical material used in orthopedic surgery, and its main component is polymethylmethacrylate (English full name polymethylmethacrylate, abbreviated as PMMA). Bone cement has been used in orthopedic surgery for many years, mainly in artificial joint replacement and vertebroplasty. [0003] PMMA bone cement is a room-temperature-curing polymer material, which is usually provided in a set of liquid and powder, and the liquid and powder need to be mixed before use during surgery. The mixed liquid and powder will undergo thermogenic polymerization reaction, and the polymerization can be divided into four basic steps: (1) Mixing stage: Stir the bone cement powder and liquid to make it homogenized, ...

AI Technical Summary

Problems solved by technology

[0004] During the mixing period of bone cement processing, it is necessary to use mixing equipment to mix bone cement powder and liquid. However, the existing mixing device has a single function and cannot test the anti-collapse performance of bone cement in the hardening period, and the gas generated during the mixing process The pungent smell in the volatile part is harmful to human health
