[0002] Microspheres are spherical particles made of inorganic or polymer materials. They can combine materials with different structures and properties in a certain way to complement each other's advantages. Microspheres have excellent properties such as fluidity, biocompatibility, functional base characteristic surface effect, volume effect, etc. According to the morphology, they can be divided into solid microspheres, double-layer microspheres, hollow microspheres, and porous microspheres. According to the different materials, microspheres can be divided into inorganic microspheres and organic microspheres.

[0003] One end of the existing smearing device is soaked in a reagent bottle through a cotton swab. After the solution is soaked, the soaked cotton swab is controlled to smear the smearing area. Since the solution on the cotton swab is effective, the work efficiency is low, and when the cotton swab is smearing the smearing area, it is easy to use too much force, which reduces the patient's comfort.

[0004] In view of this, we propose a microsphere smear device for in vitro diagnosis. Utility Model Content
