Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to a battlefield rescue horizontal infusion device. Background Art

[0002] The existing traditional infusion device requires medical staff to carry the infusion bag or use an infusion pole to hang the infusion bag. The existing infusion method has the following problems:

[0003] 1. It is easy to expose the target. The way medical staff carry infusion bags or use infusion poles to hang infusion bags makes them lack of concealment ability and expose them to the enemy's field of vision, thus posing a serious threat to the lives of medical staff and the wounded and sick.

[0004] 2. It consumes manpower. The infusion method of carrying an infusion bag requires an additional medical staff member to work, and the staff member cannot free his hands to carry a stretcher or do other rescue work.

[0005] 3. Waste of resources. The infusion pole is hung on the infusion bag for infusion, which requires carrying the infusion pole, increasing the carrying materials and bringing the weight and burden during wartime. In addition, when transporting a large number of wounded and sick people in the field, on the battlefield, or in disaster relief, there may be insufficient infusion poles or no infusion poles at all.

[0006] This shows that it is extremely urgent to design a battlefield rescue horizontal infusion device.
