Technical field

The utility model relates to the technical field of blood transfusion, in particular to a blood transfusion bag.

Background technique

Blood transfusion is a method of replenishing blood to the body after illness or injury. Blood transfusion usually takes one to four hours, depending on the blood demand. Blood transfusion is usually relatively normal. Blood transfusion is an important medical method. Blood transfusion is usually They all use blood transfusion bags, which are convenient for storage and use, so the quality of the blood transfusion bags is particularly important.

For example, the authorized publication number is a blood transfusion bag disclosed in CN216908628U. The top of the blood bag is provided with a drainage tube extending into the blood bag. One side of the drainage tube is provided with a backup drainage device. The backup drainage device includes a drainage cover located on the top of the blood bag. , the inner cavity of the drainage cover is connected with the inner cavity of the blood bag, the side wall of the drainage cover is provided with a jack, the jack can be sealed by a hole plug, the inner cavity of the drainage cover is provided with a sealing plate that closes the inner cavity of the blood bag, and the sealing plate passes through The colloid is connected to the wall of the inner cavity of the drainage cover. The top of the drainage cover is provided with a pull ring that extends into the inner cavity of the drainage cover and is connected to the sealing plate. Although it solves the problem that during the use of the blood transfusion bag, medical staff need to remove the drainage tube on the blood transfusion bag. It is connected to the pipeline of the blood transfusion device to supply blood to the patient. However, the sealing port of the drainage tube is often not up to standard due to the production process, making the material of the sealing port too hard. As a result, the sealing port cannot be easily inserted, which often occurs during repeated insertions. If the sealing port is broken, it will be impossible to connect the drainage tube and the blood transfusion device, causing the entire bag of blood to be wasted;

When the existing blood transfusion bag is used, due to its relatively single structure, it is easy to be damaged when punctured by sharp needles and the like, causing plasma to flow out, causing economic losses and pollution. For this reason we propose a blood transfusion bag.
