Blood cell recovery sets, centrifuge bowl type1 ScopeThis part of YY/T 1566 specifies the requirements for the centrifuge bowl type blood cell recovery set used in surgical operations. It is a single-use product to ensure the safety of use with autologous blood recovery device. This part applies to centrifuge bowl type blood cell recovery set that are intended to be used in conjunction with other autologous blood processing devices during surgery, and are expected to be used in conjunction with autologous blood recovery device. It consists of a tube system, a separation bowl, a red blood cell collection bag, and a waste solution bag. It does not include a blood collection filter (reservoir).2 Normative referencesThe following documents are essential to the application of this document.

Autologous blood reinfusion refers to the collection, storage, and reinfusion of blood products from the same patient. There are many cases where an autologous blood reinfusion is ideally useful or life-saving, especially when allogeneic blood is not immediately available. These conditions include the following types of clinical autologous blood reinfusion. a) Collection, storage and reinfusion during optional surgery or emergency during surgery; b) Collection, storage and reinfusion in the event of a life-threatening injury or major blood loss. All autologous blood reinfusion devices will have blood contact with the surrounding environment, so it will use anticoagulants, purification (filtration), washing and reinfusion. Therefore, all kinds of instruments used in these links have dangerous sources. These dangerous sources should be recognized by a standard. Due to the group of patients who use these devices, most reinfusion devices do not have an advantage in avoiding dangerous sources. Because most reinfusions need to handle one or more circulating blood volumes, such a procedure will amplify the deleterious effects on blood (proteins, forming elements, etc.). Moreover, since autologous blood reinfusion devices more or less form the extracorporeal blood circuit, regardless of the intended use or application of these devices, the performance criteria of these devices should consider the performance of such aspects as the extracorporeal circuit of cardiac surgery and non-cardiac surgery. The blood collected from the open wound surface is in contact with external substances other than air, thromboplastin, chips, fat, and other circulatory systems, so it is contaminated blood. Air can be removed through the reservoir, which is usually not a problem in autologous blood reinfusion devices equipped with an external oxygenator. However, when using the direct blood contact interface to quickly introduce blood into the patient with air pressure, air pollution becomes a problem. Because there is no air capture device in the oxygenator, it is dangerous to use Note. When the manufacturer gives the centrifuge speed, the test is carried out in accordance with the centrifuge speed given by the manufacturer. Otherwise, the test is carried out in accordance with the centrifuge speed of 5600 r/min. B.5 Residual amount At 23 °C ± 2 °C ambient conditions, WEIGH (accurate to 0.1 g) separation bowl, PLACE it in the autologous blood recovery set, in accordance with conventional use method or instruction manual, INSTALL and CONNECT the centrifugal bowl type blood cell recovery set, USE the distilled water at 23 °C ± 2 °C as a circulation solution. MAKE adjustment and control in accordance with autologous blood recovery set operating procedures, MAKE it circulate once at the centrifuge speed 5600 r/min, after the reinfusion is completed, WEIGH the separation bowl again, USE the difference between the two weighing results divided by the water density (taken as 1 g/mL) to obtain the separation bowl blood residual amount. Note. When the manufacturer gives the centrifuge speed, the test is carried out in acc... ......Source: Above contents are excerpted from the full-copy PDF -- translated/reviewed by: www.ChineseStandard.net / Wayne Zheng et al.
