摘要： Centrifugation systems and methods are provided for separating blood into its constituent parts. Inner and outer walls of a centrifuge each include a projection which extends toward the other wall. A separation chamber is received in the centrifuge between the walls, with the chamber including an inlet port for flowing blood into the chamber, a plasma outlet port for flowing plasma out of the chamber, and a red cell outlet port for flowing red blood cells out of the chamber. With the chamber received in the centrifuge between the walls, the first projection extends into the path of separated blood components flowing toward the plasma outlet port and prevents cellular blood components from flowing into the plasma outlet port. The second projection extends into the path of separated blood components flowing toward the red cell outlet port and prevents plasma from flowing into the red cell outlet port.

摘要： Blood separation methods are provided for mid-processing calculation of blood composition. Blood is conveyed into a device having an outlet line and the device is spun to separate platelets from the blood. A flow of platelets is conveyed from the device by the outlet line and the platelets in the outlet line are optically measured. With said optical measurement, a current platelet yield, a platelet pre-count, the volume of blood to process to collect a target amount of platelets, and/or the processing time required to collect a target amount of platelets is calculated. The optical measurement can also be used to calculate an amount of storage fluid to convey into a collection container with the platelets.

摘要： A mouthpiece is provided having a quick connect coupler to facilitate the rapid replacement of mouthpieces for use with breathing devices that may be used by many different individuals, such as in diver training classes and rental operations. In a preferred embodiment, the mouthpiece has a coupler including a pin to engage and lock with a slot in an opening of the regulator housing. The mouthpiece can further include one-way inhalation and exhalation pathways to prevent pathogenic entities in the exhalation and saliva of the diver from contaminated the body of the regulator. An exhaust tee is provided to direct bubbles away from the diver's line of vision. The regulator housing can further include an independent exhaust valve opening. A seal is provided to prevent the regulator body from flooding through the exhaust valve opening when the regulator is used with a mouthpiece having its own exhalation pathway. A flapper valve replaces the exhaust valve opening seal to permit conventional operation when the regulator is used with a conventional mouthpiece after being taken out of service for use by multiple users.

摘要： A supporting guide for an oxyacetylene torch provides a body having spaced legs defining a recess therebetween to carry gas supply pipes of the torch for releasable attachment of the supporting guide to the supply pipes. A body portion distal from the recess pivotally carries a disk carrying a support arm extending spacedly therefrom for pivotal motion relative to the body to support the torch and guide it on a workpiece or a template. The support arm is carried by the disk for adjustable extension and angulation relative to the body to regulate the distance of a torch nozzle from a workpiece and the angulation of the torch nozzle relative to the workpiece.

摘要： A separation zone for separating platelets from a platelet-rich suspension establishes a relationship between its radial thickness (h) and axial height (Z) that, taking into account the given angular velocity of rotation and the given kinematic viscosity of the platelet-rich suspension introduced through the inlet, represents a (.lambda.) value that is less than 700, where ##EQU1## where: .OMEGA. is the angular velocity (in rad/sec); h is the radial depth (or thickness) of the chamber (in cm); .nu. is the kinematic viscosity of the fluid being separated (in cm.sup.2 /sec); and Z is the axial height of the chamber (in cm).

摘要： Systems and methods take into account that the spleen normally holds a number of platelets in reserve out of circulation. During blood processing, the spleen releases these platelets into the donor's circulatory system, making them available for collection. The systems and methods estimate the number of platelets N.sub.SPLEEN held in reserve by the spleen in a human body. The systems and methods derives a splenic mobilization function (Spleen), which can be expressed as a function of a precount of platelets Plt.sub.PRE. The systems and methods estimate N.sub.SPLEEN where: N.sub.SPLEEN =(Spleen-1).times.Plt.sub.PRE .times.DonVol where DonVol is blood volume in the body. The systems and methods can also estimate the total number of platelets N.sub.PLT in a human body, taking the Spleen function into account, where: N.sub.PLT =Plt.sub.PRE .times.Spleen.times.DonVol

摘要： Systems and methods centrifugally separate mono nuclear cells from whole blood in a separation chamber. The systems and methods control the exit hematocrit value of red blood cells separated in the chamber by recirculating a portion of the red blood cells removed from the chamber for mixing whole blood entering the separation chamber. The systems and methods also control the entry hematocrit value of whole blood entering the separation chamber by recirculating a portion of the plasma constituent removed from the separation chamber for mixing whole blood entering the separation chamber.
