The invention discloses a glass slide containing device for clinical examination. The glass slide containing device comprises a main body and glass slides, wherein placement grooves are uniformly formed in the upper surface of the main body, the glass slides are placed inside the placement grooves, the edge of the upper surface of the main body is hinged with a cover body, a hasp is arranged on a side surface of the cover body, a lock matched with the hasp is arranged on a side surface of the main body, water outlet holes are formed in the internal lower surface of the placement grooves, and a water storage device is arranged below the water outlet holes inside the main body. The glass slide containing device is simple in structure and is economical and practical, thereby facilitating popularization and application; the water storage device is arranged below the water outlet holes inside the main body, so that water, remaining after the glass slides are cleaned, can be stored in a water storage trough; cleaning can be carried out by drawing out a sliding plate and is convenient, so that troubles of working personnel are reduced, and the working efficiency is increased; a cross-sectional shape of each placement groove is a trapezoid with a wide upper side and a narrow lower side, so that the pick and place of the glass slides are facilitated; cushion pads are arranged at both inner side surfaces of the lower part of each placement groove, so that the placement grooves can play a role in protecting the glass slides.
