Technical Field

[0001] The present invention relates to the technical field of medical instruments, in particular to a safety control device for nursing infusion. Background Art

[0002] Infusion, or large-volume injection, refers to a large-dose injection that is administered intravenously, with a single dose of more than 100 ml. It is a branch of injections, usually packaged in glass or plastic infusion bottles or bags, and does not contain antibacterial agents. When used, the drip rate is adjusted through the infusion set to continuously and stably deliver the drug into the body.

[0003] Chinese invention patent CN215194542U discloses an intravenous infusion nursing management device, including a supporting device, a connecting device, a blocking device and a control device, wherein the supporting device includes a supporting frame, the connecting device includes a limiting hole and an infusion bottle slot, the blocking device includes an extrusion cylinder and a fan-shaped limiting plate, and the control device includes a controller and a gravity sensor. The present invention discloses an intravenous infusion nursing management device, wherein an insulation layer is arranged on the side wall of the supporting frame to slow down heat loss, so as to prevent the temperature of the medicine from being too low due to the influence of the external environment, the gravity sensor senses the gravity of the infusion bottle, and the controller controls the operation of the extrusion cylinder according to the reduction of the weight of the medicine in the infusion bottle, and the cylinder drives the arc-shaped extrusion plate to move and squeeze the infusion tube to intelligently block the infusion, so that medical staff do not need to monitor the remaining amount of the infusion bottle for a long time, thus reducing the workload of medical staff, and at the same time avoiding the occurrence of blood backflow caused by the failure to block the infusion tube in time after the injection of the medicine.

[0004] In order to prevent blood from flowing back, a blocking device and a control device are installed on the above-mentioned control device.
