Page 20: Boot Sequence
This section describes the boot sequence and when to interrupt that sequence for troubleshooting and maintenance purposes. When it is turned on, the Trima Accel device performs a low-level memory check, generating an alarm if this check fails. If this check is successful, the device moves on to the boot sequence.
Page 21: Blood Collection Process
Figure 1-6: Trima Accel fluid flow diagram First, the disposable tubing set is loaded onto the Trima Accel system. Once the cassette is loaded, the Trima Accel system prompts the operator to clamp both the needle line and the sample bag line. The anticoagulant (AC), return, and inlet pumps are run to pressure test the tubing set.
Page 22 The control and safety computers monitor several items during startup of the procedure. The first return cycle is monitored closely due to the high amount of AC in the Trima Accel system during startup. An over-delivery of volume during the first return cycle results in a safety shutdown of the Trima Accel system for this reason.
Page 23: Pump System
Operational Description Pump System The Trima Accel device uses five pumps to move anticoagulant, blood, and blood components through the disposable tubing set using peristaltic action. Each pump consists of a pump motor, a pump rotor, a seal, and a raceway housing. The platelet pump spins at a significantly slower rate than the rest of the pumps, so it needs two magnets in the rotor to properly measure speed.

Page 142: Power Fail Recovery State
This state begins with a handshake across domain boundaries between control and safety computers. The Trima Accel system tries to restore data (in the power fail save file) from a previous procedure if there is any valid data. If there is valid data, the Trima Accel system performs the power tests that are normally performed in the Startup Tests state and then restores the previous data.
Page 143 At the end of this substate, the 24-volt switch remains ON and the 64-volt switch is turned OFF. If any test fails, an alarm is generated, and the Trima Accel system resumes at the beginning of Startup Tests. If all conditions are met, the Trima Accel system advances to the Valves Test substate.
Page 144 10 seconds, an alarm is generated and the Trima Accel system resumes at the beginning of the Startup Tests state. If this test passes, the Trima Accel system advances to the Leak Detector Test substate.

Disposable Tests Substates The disposable tests are a sequential series of automated tests designed to ensure that the tubing set is properly loaded and functioning correctly.
Page 149 This test commands the AC, return, and inlet pumps until each has achieved one-third of a revolution. The Trima Accel system advances to the Negative Press Test state if the exit condition is satisfied. If the test fails, pressing the button returns to the Press Inlet Line substate.
Page 150 This final disposable test substate commands a pump until the access pressure sensor reading is greater than a version-specific predetermined amount. If this does not occur before the exit condition, an alarm is generated. When this pressure is achieved, the disposable tests are complete, and the Trima Accel system advances to the AC Connected state.
Page 151: Ac Connected State
If performing an RBC collection procedure, touching the button advances the Trima Accel Continue system to the Replacement Fluid screen, otherwise the Trima Accel system advances to the AC Prime state.

Page 153: Blood Prime State
The Trima Accel system begins priming the tubing set with the donor's blood during the Blood Prime state. The access pressure sensor alarms are enabled for the first time, the centrifuge starts, and the Trima Accel system begins updating and displaying collection procedure information. This system state ends when fluid is detected at the lower-level sensor and the centrifuge runs at the commanded speed.
Page 154 This substate moves the platelet, plasma, and RBC valves to vent pressure from the product bags built up during the previous substate. When the valves reach the open position, the Trima Accel system advances to the Evac Reset Valves substate.
Page 155: Blood Run State
The Trima Accel system performs single needle draw and return cycles and controls pump speed commands accordingly during this system state. The “RBC Spillover” alarm, all AC related alarms, and the hypovolemic alarm are activated at this time. When the Blood Run state completes, the Trima Accel system advances to the Blood Rinseback state.
Page 156 AC pump (Qac). The plasma and platelet pumps are commanded to run at version- specific speeds until a predetermined volume has been pumped into the channel. The Trima Accel system advances to the Prime Channel 2 substate.
Page 157 The plasma and platelet pumps are commanded to version-specific speeds. The Trima Accel system begins checking for fluid at the upper reservoir sensor and executes return cycles as necessary. After a version-specific inlet volume has been pumped, the Trima Accel system advances to the Prime Vent substate.
Page 158 2 minutes, a centrifuge hardware alarm is generated. The platelet valve is commanded back to the return position while the pumps and centrifuge remain at their previous speeds. When the machine goes from the first draw cycle to the first return cycle the Trima Accel system advances to the Remove Channel Air substate.
Page 159 The AC and inlet pump speeds change to keep the AC infusion rate at the run configured value. After enough inlet volume has been processed to stabilize the LRS chamber, the Trima Accel system advances to the Platelet Plasma substate or the Pre-Platelet No Plasma substate.
Page 160 The platelet valve now opens while the plasma valve remains open until the volume target is achieved. If the plasma volume target is small, the plasma valve closes and the Trima Accel system advances to the Mid Run substate. If the volume target is large, the plasma valve remains open and the Trima Accel system advances to the Extended Plasma substate.
Page 161 This substate occurs after all plasma is collected during the Platelet Plasma substate. This substate only occurs if the Trima Accel system calculates that the volume in the platelet bag will be lower than it should be by a predetermined volume after the Mid Run substate. This usually occurs when the concurrent plasma product collected is a small or medium product.
Page 162 This substate occurs after the Mid Run substate if the collect flow is less than a predetermined rate during Platelet Only Collection. Otherwise, the Trima Accel system skips this substate and advances to the Extended PCA substate. During Platelet Inventory Recovery the platelet pump ramps up in speed to its maximum value and continues running until predetermined platelet volume has been pumped.
Page 163 This substate occurs after all platelets are collected and additional plasma is necessary to achieve the plasma target. The platelet valve closes and the plasma valve moves to the collect position. After the plasma target is achieved, the Trima Accel system advances to the RBC Collect substate if RBC is chosen.
Page 164 The Blood Run state contains eleven recovery substates. Recovery substates interrupt the procedure and suspend the procedure time clock. When the recovery routine completes, the Trima Accel system returns to the procedure substate that it was in prior to recovery. These recovery substates can occur at any time during the Blood Run state.
Page 165 After a predetermined volume of saline has been pumped, the Trima Accel system resumes the draw or return cycle that it was previously Saline Prime (Replacement Fluid Priming Recovery) Substate This substate occurs the first time replacement fluid is administered in an RBC/Plasma procedure.
Page 166: Rinseback State
All valves are commanded to the return position and the inlet, AC, plasma, and platelet pumps are commanded to zero. The return pump runs until air is present at the lower-level sensor, or a predetermined volume of return has been pumped. The Trima Accel system then advances to the Rinseback Recirculate substate.
Page 167 The centrifuge is commanded to zero. The inlet pump is also commanded to zero and the plasma, platelet, and return pumps run until the lower-level sensor sees air and a predetermined return volume is processed.

The Trima Accel system begins checking for fluid at the upper reservoir sensor and executes return cycles as necessary. After a version-specific inlet volume has been pumped, the Trima Accel system advances to the Prime Vent substate.
Page 238 2 minutes, a centrifuge hardware alarm is generated. The platelet valve is commanded back to the return position while the pumps and centrifuge remain at their previous speeds. When the machine goes from the first draw cycle to the first return cycle the Trima Accel system advances to the Remove Channel Air substate.
Page 239 The AC pump turns off, and the plasma, platelet, and return pumps are commanded to version-specific speeds to remove air from the channel. When a version-specific inlet volume has been pumped, the Trima Accel system advances to the Blood Run Collection substates. Table 3-170: Prime Airout 2 Substate...
Page 240 The AC and inlet pump speeds change to keep the AC infusion rate at the run configured value. After enough inlet volume has been processed to stabilize the LRS chamber, the Trima Accel system advances to the Platelet Plasma substate or the Pre-Platelet No Plasma substate.
Page 241 This substate occurs after all plasma is collected during the Platelet Plasma substate. This substate only occurs if the Trima Accel system calculates that the volume in the platelet bag will be lower than it should be by a predetermined volume after the Mid Run substate. This usually occurs when the concurrent...
Page 242 During this substate the plasma valve moves to the return position and adds plasma to the platelet bag to reach the needed volume. When the target volume is added to the platelet bag, the Trima Accel system advances to the Mid Run substate. Table 3-176: PCA Substate...
Page 243 This substate occurs after the Platelet Plasma substate (and the Mid Run substate if it occurs) and prior to collecting additional plasma. It only occurs if the Trima Accel system calculates that the volume in the platelet bag is lower than it should be by a predetermined volume or more after the Mid Run substate.
Page 244 This substate occurs in both platelet/plasma/RBC procedures and DRBC procedures. All valves move to the return position and all pumps are commanded to zero. When these actions successfully complete, the Trima Accel system advances to the Blood Rinseback state. Table 3-184: Pre Rinseback Substate...
Page 245 The Blood Run state contains eleven recovery substates. Recovery substates interrupt the procedure and suspend the procedure time clock. When the recovery routine completes, the Trima Accel system returns to the procedure substate that it was in prior to recovery. These recovery substates can occur at any time during the Blood Run state.
Page 246 After a predetermined volume of saline has been pumped, the Trima Accel system resumes the draw or return cycle that it was previously Saline Prime (Replacement Fluid Priming Recovery) Substate This substate occurs the first time replacement fluid is administered in an RBC/Plasma procedure.
Page 247: Blood Rinseback State
All valves are commanded to the return position and the inlet, AC, plasma, and platelet pumps are commanded to zero. The return pump runs until air is present at the lower-level sensor, or a predetermined volume of return has been pumped. The Trima Accel system then advances to the Rinseback Recirculate substate.
Page 248 , the Trima Accel system advances to the Continue Donor Disconnect state. If the operator does not respond to the prompt in 10 minutes, the Trima Accel system automatically advances to the Donor Disconnect state. Table 3-188: Disconnect Prompt Substate...
Page 249: Donor Disconnect State
Disconnect Test Substate The inlet pump is commanded to a predetermined speed, and the Trima Accel system waits to verify that the access pressure drops by a predetermined amount within 30 seconds. Then the system checks that the pressure does not decay by more than a predetermined amount within the following 10 seconds. If both tests fail, a disconnect test alert is displayed and the Trima Accel system repeats the test.
Page 250 Raise Cassette Substate The cassette is commanded to the raised position while the pumps are running at their unload speeds. When the cassette is detected in the raised position, the Trima Accel system advances to the next substate. Table 3-192: Raise Cassette Substate...
Page 251: Metered Storage Solution State
The Metered Storage Solution (MSS) state administers the automatic addition of metered storage solution. This system state begins when the Trima Accel system determines if the run is a normal metered storage run or a “salvage case.” This is determined by flags during the Rinseback protocols. A “salvage case” is defined as a run where the machine does not return sufficient volume from the reservoir and channel back to the donor.

Page 259: Metered Storage Solution Disconnect State
The MSS Disconnect state checks that the operator has correctly sealed the product and additive solution bags following the MSS state. Upon completion of the MSS state, the Trima Accel system waits for the operator to confirm the products and storage solution have been disconnected. After the operator confirms this information, the system unloads the cassette and proceeds to the Post Run state.
