An Erythropheresis machine being used for plasmapheresis The automated method uses a very similar process. The difference is that the collection, separation, and return are all performed inside a machine connected to the donor through a needle in the arm, typically the antecubital vein. There is no risk of receiving the wrong red cells. [27]
This allows the apheresis machine to repeat the draw-centrifuge-return cycle to obtain more platelets. The bulk of the machine and the length of the donation process means most platelet donations are done in blood centers instead of mobile blood drives. Each country has its own rules to protect the safety of both donor and recipient.
The assembly (A–D), operation (E) and disassembly (F) of the platelet apheresis machine, which can be configured to separate other components as well. The various apheresis techniques may be used whenever the removed constituent is causing severe symptoms of disease. Generally, apheresis has to be performed fairly often, and is an invasive ...
Hemoperfusion or hæmoperfusion (see spelling differences) is a method of filtering the blood extracorporeally (that is, outside the body) to remove a toxin.As with other extracorporeal methods, such as hemodialysis (HD), hemofiltration (HF), and hemodiafiltration (HDF), the blood travels from the patient into a machine, gets filtered, and then travels back into the patient, typically by ...
Intraoperative blood salvage (IOS), also known as cell salvage, is a specific type of autologous blood transfusion. Specifically IOS is a medical procedure involving recovering blood lost during surgery and re-infusing it into the patient.
In contrast, so-called "vampire filler" is autologous platelets used as dermal filler in the platelet-rich fibrin matrix method of cosmetic surgery; [9] it is generally not described as autohemotherapy and the FDA-approved machines for it are approved for use by only licensed surgeons.

Cardiopulmonary bypass (CPB) or heart-lung machine, also called the pump or CPB pump, is a machine that temporarily takes over the function of the heart and lungs during open-heart surgery by maintaining the circulation of blood and oxygen throughout the body. [1] As such it is an extracorporeal device. CPB is operated by a perfusionist. The ...
The patient's blood is removed and replaced by donated blood or blood components. This exchange transfusion can be performed manually or using a machine . [2] Most blood transfusions involve adding blood or blood products without removing any blood, these are also known as simple transfusions or top-up transfusions. [3] [4]
