Blood transfusion bag capable of preventing blood coagulation

Abstract

The invention discloses a blood transfusion bag capable of preventing blood coagulation. The blood transfusion bag comprises a plastic soft film material layer, a filter element structure is fixedly arranged at the upper end of the interior of the plastic soft film material layer, and a blood inlet is fixedly formed in the upper end of the side, close to the filter element structure, of the plastic soft film material layer through a connecting piece; an anticoagulant injection port is formed in the end, away from the blood inlet, of the upper end of the plastic soft film material layer through a connecting piece, an outer protection layer is connected to the four corners of the outer side of the plastic soft film material layer through connecting pieces, a first hanging ring is fixedly arranged in the center of the upper end of the outer protection layer, and an air inlet is fixedly formed in one side of the first hanging ring; an exhaust port is fixedly formed in the lower end of the outer protection layer, an infusion pipeline is arranged in the center of the lower end of the plastic soft film material layer, a blood storage pipe is fixedly arranged at the lower end of the infusion pipeline, and a first sealing rubber ring is fixedly arranged at the bottom end of the blood storage pipe. Therefore, the situation of blood coagulation during blood transfusion is effectively avoided, and the blood transfusion bag is suitable for being widely popularized.

Description

technical field [0001] The invention belongs to the technical field of medical equipment, in particular to a blood transfusion bag for preventing coagulation. Background technique [0002] Blood transfusion is one of the commonly used and important medical methods. At present, clinically used blood transfusion bags mainly include a bag body and a blood transfusion tube connected to the bottom end of the bag body, and the top of the bag body is provided with a hanging hole. When transfusing blood to a patient, since the temperature of the blood in the blood transfusion bag is different from the temperature of the human body, it is easy to make the patient feel uncomfortable. In addition, in order to avoid blood coagulation during blood transfusion, medical personnel have to constantly shake the bag body, which increases their work intensity. At the same time, when carrying out first aid to patients with excessive blood loss, the delivery speed of blood must be accelerated, ...
