Description

Medical multifunctional pen Technical Field The utility model relates to the technical field of medical appliances, in particular to a medical multifunctional pen. Background In medical care operations, the opening of the ampoule is a frequent and critical step. When the ampoule bottle opening method is used, medical staff needs to hold the grinding wheel with one hand and rub ampoule bottle necks with force, cutting force is difficult to control, glass scraps are easy to splash, and scratch risks exist. Traditional grinding wheel or cutterbar only possess single function, and medical personnel need use notes, illumination simultaneously when dispensing (especially at night or light not enough scene), and frequent switching instrument reduces work efficiency. The existing cutting tool lacks a debris collecting function, splashed glass scraps can pollute the dispensing environment and even fall into liquid medicine, so that the safety of patients is threatened. The integrated medical pen disclosed in the patent publication No. CN210652431U comprises a pen body and a grinding wheel arranged at the tail end of the pen body. The patent publication number CN202508856U is a convenient medical ampoule bottle cutting pen which consists of a pen cap, an upper tube body, a lower tube body, a circular slip ring, a plurality of sheet bodies and a triangular grinding wheel. Above-mentioned technical scheme all discloses setting up the grinding wheel and realizing cutting function on the pen, but not design piece collection structure, can't effectively block piece splash. Disclosure of utility model The utility model provides a medical multifunctional pen which is convenient to use and can effectively prevent fragments from splashing.
