Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of medical devices, and in particular to a stable pressurizing device for medical emergency blood transfusion and infusion bags. Background Art
[0002] In the field of medical emergency, blood transfusion and infusion are extremely critical treatment methods. The accuracy and timeliness of their operation are directly related to the patient's life safety and treatment effect. In some emergency situations, such as massive blood loss and shock, blood or liquid medicine needs to be quickly and stably infused into the patient's body to maintain the patient's vital signs and ensure the effectiveness of the treatment. Therefore, flow rate control during blood transfusion and infusion is crucial.
[0003] Traditional blood transfusion and infusion methods mainly rely on gravity to achieve liquid delivery, which can generally meet conventional treatment needs. However, when the patient is in a critical state and needs to quickly replenish blood or liquid medicine, the flow rate of gravity infusion is far from meeting the treatment requirements. To solve this problem, the existing method is usually to directly pressurize the blood transfusion and infusion bag to increase the flow rate of the liquid by increasing the pressure. However, this direct pressurization method has many disadvantages. On the one hand, it is difficult to achieve precise control of pressure by direct pressurization. Excessive pressure can easily lead to too fast infusion speed, which may cause serious complications such as heart failure and pulmonary edema in patients; if the pressure is too low, the expected rapid infusion effect cannot be achieved, delaying the time of treatment. On the other hand, the direct pressurization method is prone to unstable pressure, resulting in fluctuations in the infusion flow rate, which not only affects the treatment effect, but also may have adverse effects on the patient's body.
[0004] In addition, the operation process of direct pressurization is relatively cumbersome, and medical staff need to adjust the pressure frequently, which increases the workload. In the case of emergency treatment, which is a race against time, too many operation steps may distract medical staff and affect the efficiency of treatment. Moreover, direct pressurization equipment is usually large in size and inconvenient to carry, and its use in some emergency scenarios (such as ambulances, field rescue, etc.) is limited.
