Blood transfusion bag capable of reminding and avoiding use of invalid blood

Abstract

The invention discloses a blood transfusion bag capable of reminding and avoiding use of invalid blood. The blood transfusion bag comprises a blood transfusion bag, a timer, a detection box, a blood supply tube, a one-way valve, a detection cavity, a spring, a sealing column, a pH value detection column and an adjusting column. The blood transfusion bag capable of reminding and avoiding use of invalid blood is smart in structure; firstly, due to timed reminding designing, the storage time of a blood bag can be detected, and the problems that the blood bag exceeds the limit time and is invalidcan be avoided; secondly, due to cooperation of a blood pH value testing mechanism, the pH value of blood can be accurately detected, blood judgment can be facilitated, and the problems that the bloodis invalid because of ambient temperatures and the like and medical operators cannot know the situation rapidly can be avoided; and in a word, the later blood transfusion security of patients can beensured, and popularization and application in blood transfusion departments of hospitals can be facilitated.

Description

technical field [0001] The invention relates to a blood transfusion bag, in particular to a blood transfusion bag capable of reminding and avoiding failure blood to be used again. Background technique [0002] As we all know, the blood transfusion bag is to store blood, and when the patient needs blood transfusion, only the blood in the blood transfusion bag can be infused to the patient through the vein. [0003] According to the above, during the storage and protection of blood transfusion bags in the current clinical blood transfusion department, due to ambient temperature, time or human factors, the stored blood transfusion bags fail. Before the patient's blood transfusion, the blood inside the blood bag needs to be tested, but because the existing detection methods are generally cumbersome, it is necessary to cut the blood sample bag on the side of the blood bag in advance, and then draw the blood for the corresponding test, which is not only laborious, And also prolon...

Problems solved by technology

[0003] According to the above, during the storage and protection of blood transfusion bags in the current clinical blood transfusion department, due to environmental temperature, time or human factors, the stored blood transfusion bags become invalid. Before the patient's blood transfusion, the blood inside the blood bag needs to be tested, but because the existing detection methods are generally cumbersome, it is necessary to cut the blood sample bag on the side of the blood bag in advance, and then draw the blood for the corresponding test, which is not only laborious, And it also prolongs the patient's waiting time for blood transfusion greatly, which restricts the clinical application. In view of the above defects, it is necessary to design a blood transfusion bag that can remind and avoid the reuse of invalid blood.
