The present application relates to an optical measurement device applied for measuring a syringe. The optical measurement device comprises a body, a light source unit, a light sensing unit, and a driving unit. The body includes a fixing groove. The light source unit is disposed corresponding to a side of the fixing groove. The light sensing unit is disposed opposite to the light source unit and receives the light beams emitted by the light source unit. The driving unit connects and drives the light sensing unit to measure the content of the syringe.本發明涉及一種光學量測裝置,用於量測一注射器。該光學量測裝置包含一本體、光源元件、光感測元件以及傳動元件。該本體包含一固定槽。光源元件設置於該固定槽之一側。光感測元件設置於該光源元件之相對側並接收該光源元件所發射之光線。該傳動元件連接並驅動該光感測元件而量測該注射器之容量。500...光學量測系統510...光學量測裝置511...光源元件512...光感測元件513...傳動元件520...處理器530...顯示器540...電源裝置550...記憶體560...無線傳輸器570...溫度感測器580...冷卻器590...警示器600...感測器610...按鍵
