Blood product infusion intelligent auxiliary system for preventing platelet aggregation

Abstract

The invention discloses a blood product infusion intelligent auxiliary system for preventing platelet aggregation. The system comprises a base plate, a negative pressure contraction assembly, a negative pressure source, a valve set and a control module. In the working process, a blood transfusion bag is hung on a hook of the base plate, the negative pressure contraction assembly is arranged on the base plate, and the negative pressure contraction assembly can extrude the blood transfusion bag in the direction of the base plate when contracting under the negative pressure effect; and then the negative pressure source is controlled by the control module to provide negative pressure for the negative pressure contraction assembly, the negative pressure contraction assembly is repeatedly switched between the negative pressure state and the atmospheric pressure state through a control valve set, then the negative pressure contraction assembly repeatedly extrudes the blood transfusion bag, and oscillation of blood products in the blood transfusion bag is achieved. Therefore, platelet aggregation in the platelet infusion process can be effectively avoided, blood product oscillation is achieved based on negative pressure driving, the system is made to be smaller, and clinical application and popularization are facilitated.

Description

technical field [0001] The invention relates to the technical field of medical engineering, in particular to an intelligent auxiliary system for transfusion of blood products for preventing platelet aggregation. Background technique [0002] Platelet blood transfusion is a part of component blood transfusion. Since platelets are easy to coagulate, platelets in the blood bank are stored under vibration or cryopreservation. In terms of vibration storage, the ambient temperature is required to be 22±2°C, and the platelet shaker is set at 60 times. The platelets are oscillated at a frequency of / min. When the platelets are out of the warehouse, due to changes in temperature, oscillation mode and other conditions, to prevent platelet aggregation and ensure the effectiveness of platelet transfusion, it is necessary not only to reduce the transfusion time as much as possible, but also to perform strict nursing care by medical staff and frequently Observe the appearance of the plat...

AI Technical Summary

Problems solved by technology

[0003]However, it is difficult to ensure stable vibration frequency and amplitude by artificial oscillation, which may easily cause platelet vibration uneven and increase the risk of platelet aggregation

Moreover, in clinical practice, since the specifications of platelets stored in the blood bank are uniform, for different patients, it is necessary to manage the amount of platelets transfused, especially for patients such as infants and children, the required transfusion time longer
