[0002] Bypass sample bags are usually used to collect blood samples for clinical testing or blood research. The purpose of the design of this bag is to retain a portion of the blood in the bag while collecting blood, so that subsequent tests or research can be carried out without affecting the original collected blood. This method allows medical personnel to obtain sufficient samples for various tests without the need for additional blood collection, while also reducing the discomfort and pain of patients. At present, when medical blood collection departments, blood donation rooms, blood stations and laboratories use bypass sample bags for sample storage, the amount of blood collected in the sample bag is generally judged by the experience of nursing staff, which is prone to excessive or insufficient blood. For this reason, we propose a bypass sample bag weighing device with a clamp. Utility Model Content
