Description

Technical Field

[0001] The utility model relates to the field of medical equipment, in particular to a perfusion machine. Background Art

[0002] The preparation of human specimens requires multiple steps of processing and preparation. In order to preserve them for a long time and avoid decay or mildew, the human blood circulation system needs to be perfused with fixative. Currently, there are traditional bottle-type, curved-type, and fully automatic antiseptic devices. Most of these devices increase the pressure by raising the liquid level to achieve a certain perfusion pressure for corpse preservation. Perfusion pressure is a key factor affecting the quality of corpse perfusion. Due to different conditions of the corpse, the pressure needs to be adjusted frequently during perfusion to achieve the best perfusion effect.

[0003] Patent No. 202123391415.0 discloses an intelligent automatic perfusion machine for human specimens, which controls the injection pump through a controller to directly extract the fixative in the fixative storage container. However, the accuracy of each injection cannot be ensured by direct extraction and injection through the pump, and the perfusion accuracy is poor. In addition, the machine cannot be effectively moved to the desired perfusion location, and has poor flexibility. Utility Model Content
