Novel blood bag

Abstract

The invention discloses a novel blood bag. The novel blood bag comprises a blood bag body, a rotating shaft is arranged on the lower wall in the blood bag body; a guide plate is arranged at the rear end of the rotating shaft; a limiting block is arranged on the right side of the rotating shaft; an exhaust pipe penetrates through the surface of the left end of the blood bag body; a first double connector is arranged at the left end of the exhaust pipe, a first guide pipe is arranged at the left end of the first double connector, a buffer bag is arranged at the left end of the first guide pipe,a second adapting pipe is arranged at the right end, close to the rear end, of the buffer bag in the penetrating mode, and an exhaust cover is arranged at the right end of the second adapting pipe. According to the blood bag, blood can circulate in the blood bag and is uniformly mixed; the blood bag has the advantages that the blood uniformity is improved, the blood bag can be conveniently and effectively exhausted, the convenience is improved, the blood in the blood bag body is effectively sealed and stored, the sealing performance is improved, and the medical blood resource loss caused by the splashing of the blood through the blood guide pipe when the blood bag body is filled with oxygen by a worker is prevented.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a novel blood bag. Background technique [0002] Blood transfusion refers to a treatment method in which blood is infused into a patient through a vein. It is widely used clinically. In the narrow sense, blood transfusion refers to the transfusion of whole blood. Strictly speaking, hematopoietic stem cells (bone marrow or peripheral blood) can also be regarded as a special kind of blood transfusion, specifically container equipment used to store medical blood. [0003] Most of the blood bags on the market have insufficient blood circulation and mixing in the blood bag, the blood uniformity is low, the blood bag cannot be effectively exhausted, the convenience is poor, and the blood in the main body of the blood bag cannot be effectively sealed Preservation, poor sealing, blood will splash out through the blood catheter when oxygen is passed to the blood bag, resulting in...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a new type of blood bag to solve the problem that most of the blood bags on the market proposed in the above background technology have blood circulation and mixing in the blood bag that is not uniform enough, the blood uniformity is relatively low, and the blood bag cannot be effectively treated. Exhaust, poor convenience, cannot effectively seal and store the blood in the main body of the blood bag, poor sealing, blood will splash out through the blood catheter when the blood bag is filled with oxygen, resulting in the loss of blood medical resources
