High speed bag type centrifugal device

Abstract

The invention discloses a centrifugal separation device, which more particular relates to a device that is used for separating inside bag blood for component separation, comprising a machine box, a motor that is arranged on the machine box, a U-shaped rotating support that is connected with a shaft of the motor, an external tumbler, a middle tumbler, an internal tumbler, a multi-cavity tube and a delivery pipe. The internal and external structure can ensure the internal tumbler to rotate at a speed that is twice that of the external tumbler, thus greatly shortening the separation time of plasma; besides, owning to high separation speed, bigger centrifugal force, fully separation and no need of twice separation, the separated blood components has high purity; furthermore, the separation device can be used for being matched with a separation bag, thus realizing continuous separation and being applicable to conditions of smaller blood sampling.

Description

technical field [0001] The invention relates to a centrifugal separation device, in particular to a device for separating components of blood in a separation bag. Background technique [0002] At present, the traditional method of collecting blood plasma is to use a separation cup. The blood separator includes a motor and a separation cup fixed on the motor. The plasma separator used with the blood separator generally consists of a separation cup, a plasma pipeline, The mechanical blood collection device and the collection bag are composed of four parts. The separation cup is placed in the centrifuge cup of the centrifuge for centrifugation. The plasma enters the plasma collection bag, and then the red blood cells in the plasma separation cup are returned to the human body. This separation method is complicated. The collection time is long, and a large amount of whole blood is required. It is not suitable for the occasion of separating a small amount of plasma, and the purit...

[0002] At present, the traditional method of collecting blood plasma is to use a separation cup. The blood separator includes a motor and a separation cup fixed on the motor. The plasma separator used with the blood separator generally consists of a separation cup, a plasma pipeline, The mechanical blood collection device and the collection bag are composed of four parts. The separation cup is placed in the centrifuge cup of the centrifuge for centrifugation. The plasma enters the plasma collection bag, and then the red blood cells in the plasma separation cup are returned to the human body. This separation method is complicated. The collection time is long, and a large amount of whole blood is required. It is not suitable for the occasion of separating a small amount of plasma, and the purity of the separated plasma is low. In addition, the components of human blood are arranged according to their specific gravity, which are red blood cells, white blood cells, and lymphocytes. , platelets and plasma, according to medical needs, only the required components will be given to the patient. For example, only the plasma needs to be separated and given to the patient, and the rest will be returned to the blood donor. This is more scientific and reasonable, and it can take care of the patient. needs, and ensure the health of blood donors to the greatest extent, it is a kind of saving for blood drug sources
