Description

Technical Field

[0001] This utility model relates to the field of infusion bags, specifically a double-layer pressurized infusion bag. Background Technology

[0002] Currently, disposable infusion sets and infusion bags are commonly used for intravenous infusions in clinical practice. However, in clinical settings, critically ill patients often require faster infusion rates or adjustments during resuscitation or treatment. A search of application CN202321031942.7 reveals a double-layered pressurized infusion bag comprising an outer pressurized bag, an infusion bag body, and an inner pressurized bag. A first air bladder is located on one side of the lower part of the outer pressurized bag. The infusion bag body is located inside the outer pressurized bag, and the inner pressurized bag is located outside the infusion bag body. A second air bladder is located on one side of the inner pressurized bag via a tubing. A connector is located at the center of one end of the infusion bag body, and a... The infusion bag has an inner pressure bag, and a second air bladder is provided on one side of the inner pressure bag via a gas delivery hose. This air bladder can internally compress the main body of the infusion bag, allowing for single-stage pressure adjustment. The inner pressure bag and the main body of the infusion bag are located inside an outer pressure bag, and a first air bladder is provided on one side of the outer pressure bag. This air bladder can pressurize both the inner pressure bag and the main body of the infusion bag. The dual-layer pressure control makes the pressure on the infusion bag more stable and precise. However, the above description still has the following defects in actual use: the infusion bag lacks an overpressure protection structure when pressurized, which can easily lead to safety hazards. It can only accelerate the flow rate of the liquid, and it lacks a structure to protect its surface. Therefore, a more practical dual-layer pressurized infusion bag needs to be designed.
