Le dispositif de co-injection (1) de la présente invention est destiné à exécuter le processus de co-injection d'aspiration d'un médicament depuis un récipient (10) au moyen d'une seringue (11) et injecter celui-ci dans un autre récipient (12). Le dispositif est capable de : détecter les largeurs respectives des images de projection de la pointe d'aiguille (11e) de l'aiguille d'injection (11c) de la seringue lorsqu'une lumière est irradiée sur la pointe d'aiguille (11e) depuis des directions multiples ; et détecter une première direction depuis le centre de l'aiguille d'injection (11c) dans la direction radiale de l'aiguille d'injection (11) vers l'extrémité pointue (11g) de l'aiguille d'injection (11c) en tant qu'orientation de la pointe d'aiguille (11e) en fonction des largeurs respectives détectées des images de projection et des directions d'irradiation de lumière respectives correspondant auxdites images de projection.
