Normal saline pump for PICC electrocardio positioning

The utility model discloses a physiological saline pump for PICC (Peripherally Inserted Central Catheter) electrocardio positioning, which comprises a pump body shell which is integrally of a hollow cylindrical structure and is made of a transparent glass material; the sealing cover is mounted outside the opening of the pump body shell, and a detachable mounting structure is formed between the sealing cover and the pump body shell through a thread structure; and the connecting block is fixedly installed in the middle of the sealing cover in a penetrating mode, and a storage liquid bag is fixedly installed outside the side face of the connecting block. According to the normal saline pump for PICC electrocardio positioning, the novel structural design is adopted, so that manual normal saline injection is replaced with the pump body, the workload of one user is reduced, constant-speed and uniform injection can be achieved when normal saline is injected through the pump body, the discomfort of a patient is reliev
