摘要:
Method and Apparatus for predicting the yield of a selected cellular component from a composite blood product by sensing the movement of the separated cellular component or another component during expression from a separation container to a collection container to produce a signal indicative of the movement, and predicting the yield of the separated cellular component from the signal.
摘要:
A container (58) constitutes a platelet separator (tertiary separator (42)) separating a platelet-containing component into platelets and another component by applying a centrifugal force. An inflow portion (77α) configured to allow the platelet-containing component to flow into a third chamber (52) and configured to allow a platelet additive solution to flow in and an accommodating portion (54a) accommodating the platelets are disposed in the container (58). Also disposed in the container (58) are an opening (78a) of an outflow port (78) allowing at least an outflow of the other component and an opening (79a) of a recovery port (79) disposed in a place different than the opening (78a) and recovering the platelets and the platelet additive solution.

A respiratory system includes a pressurized gas source coupled to a nebulizer containing a medicament. The nebulizer is connected to a breathing unit. A pressure sensitive switch detects negative pressure at the breathing unit due to inspiration and opens to provide pressured gas flow to the nebulizer. The pressure sensitive switch is configured to close prior to the end of inspiration. Residual medicament disposed in the system is cleared from the system and delivered to the patient during the remainder of the inspiration cycle. A compressor provides positive pressure to aid delivery of medicaments to the patient.
摘要:
A method of collecting mononuclear cells, comprising separating whole blood into cellular components and platelets suspended in plasma, separating the platelets suspended in plasma into platelet concentrate and platelet-poor plasma, combining the cellular components with the platelet-poor plasma to form a first mixture, and separating the first mixture into mononuclear cells and at least one component.
摘要:
Compositions and methods for separating a sample of whole blood into a substantially non-activated platelet rich plasma fraction (PRP fraction) and at least one other fraction are provided. A sample of whole blood can be centrifuged in a collection tube comprising a separator substance formulated to settle between the PRP fraction and the at least one other fraction. Preferably, centrifugation is completed without substantial activation of platelets. Optionally, the separator substance could be hardened to form a solid barrier that allows removal of all or substantially all of the platelets in the PRP fraction without remixing of the PRP fraction with the at least one other fraction.
摘要:
The invention relates to a system, comprising: a) a sample processing unit, comprising an input port and an output port coupled to a rotating container having at least one sample chamber, the sample processing unit configured provide a first processing step to a sample or to rotate the container so as to apply a centrifugal force to a sample deposited in the chamber and separate at least a first component and a second component of the deposited sample; and b) a sample separation unit coupled to the output port of the sample processing unit, the cell separation unit comprising separation column holder, a pump and a plurality of valves configured to at least partially control fluid flow through a fluid circuitry and a separation column positioned in the holder, the separation column configured to separate labeled and unlabeled components of sample flowed through the column.
摘要:
The present invention aims to provide a hollow fiber membrane module capable of producing washed platelets having a low total protein amount and a high total platelet count from a platelet suspension. The present invention provides a hollow fiber membrane module for washing platelets by removal of impurities from a platelet suspension, comprising: a housing having a platelet suspension inlet, washed platelet outlet, and filtrate outlet; and a hollow fiber membrane for filtering the platelet suspension, wherein pores through which the platelets do not pass, while the impurities pass, are formed, which hollow fiber membrane is arranged inside the housing; wherein the capacity of the inlet-side space which communicates with the platelet suspension inlet and stores the platelet suspension before being filtered through the hollow fiber membrane in the housing is 30 to 400 mL, and the module water permeability is 50 to 300 mL/Pa/hr.
