Description

Technical Field

[0001] The utility model belongs to the field of medical equipment, and in particular relates to a pressurized infusion device with infusion monitoring. Background Art

[0002] At present, the main clinical methods used to achieve the purpose of rapid liquid infusion are to increase the hanging height of the infusion bag and manually squeeze the soft-packaged liquid bag. The emergency operating room in the hospital mainly uses hand-held air bags for pressurization. Due to its limitations, the pressure is unstable, resulting in large fluctuations in flow rate and damage to red blood cells, thereby delaying rescue.

[0003] When a patient loses a lot of blood, blood must be replenished quickly, but the maximum natural flow rate of a normal blood transfusion / infusion device cannot meet the requirements of rapid infusion. Medical institutions at home and abroad use rapid pressurized blood transfusion / infusion to quickly replenish the volume of patients with massive blood loss in order to save lives. The pressurized bag is used for rapid pressurized infusion during blood transfusion and infusion, helping the liquid in liquid containers such as blood, plasma, and cardiac arrest solution (infusion bags or plastic infusion bottles) to enter the human body as soon as possible. At present, the pressurized bag is generally connected to a pressing airbag. When it is necessary to pressurize the liquid container in the infusion bag, it is necessary to manually press the airbag repeatedly to allow the airbag to inflate the pressurized bag, thereby achieving the purpose of pressurizing the liquid container inside the pressurized bag. However, it is difficult to control the pressure of the pressurized bag by manually pressing the airbag, and the operation is too cumbersome and time-consuming.
