A medical pump fixing device (1) and a medical pump. The medical pump fixing device (1) comprises a shell (10), two ratchets (11), two connecting shafts (12), and two torsion springs (13). The shell (10) comprises a first side plate (101), a second side plate (102) opposite to the first side plate (101), and two opposite third side plates (103) located between the first side plate (101) and the second side plate (102). The first side plate (101) has an inserted hole (1011) the two third side plates (103) each has an upper fixing hole (1031) and a lower fixing hole (1032) symmetrical to the upper fixing hole (1031) the two ratchets (11) are symmetrically provided in the shell (10), respectively correspond to the two upper fixing holes (1031) and two lower fixing holes (1032), and respectively have a plurality of opposite pawls (111) the two connecting shafts (12) penetrate through corresponding ratchets (11), respectively two ends of one of the two connecting shafts (12) are provided in the two upper fixing holes (1031), and two ends of the other connecting shaft (12) are provided in the two lower fixing holes (1032) the two torsion springs (13) each is provided between the corresponding ratchet (11) and the connecting shaft (12) one end of each of the torsion springs (13) is connected to the corresponding ratchet (11), and the other end thereof is connected to the connecting shaft (12). The medical pump fixing device (1) can stably fix for example components of a medical pump on an apparatus.Linvention concerne un dispositif de fixation de pompe médicale (1) et une pompe médicale.
