1 General Information Overview The T34™ Syringe Pump is a lightweight, battery-powered infusion pump, designed for ambulatory use in a hospital or homecare setting. It can deliver indicated medications via any common infusion route, including intravenous and subcutaneous. The T34™ Syringe Pump has three-point syringe detection, by which it can identify most commonly used syringe brands. This feature enables the pump to calculate the syringe volume and, depending on the mode of operation, to deliver the contents over a specified duration or at a specified rate, in milliliters per hour, therefore minimizing the risk of programming errors. Sensors activate an alarm if the syringe is removed or displaced during infusion. Other safety features include three-level access-code protection, keypad lock, event log and full alarm protection.
Figure 1: T34™ Syringe Pump in lock box
Modes of Operation The T34™ Syringe Pump can be configured and locked to one of four modes of operation. The default mode of operation is Duration Lock On. The mode-of-operation options are: Duration Lock On: Delivers the contents of the syringe over a fixed, preprogrammed duration (the pump default is 24 hours). The pump automatically calculates the ml/hr infusion rate for the confirmed deliverable volume. Duration Lock Off: This mode permits the user to set a custom duration for delivery of the infusion. The pump automatically calculates the ml/hr infusion rate based on the selected duration of delivery and the confirmed deliverable volume. Rate Lock On: Delivers the contents of the syringe over a fixed, preprogrammed rate. The pump detects the volume of the syringe and calculates the duration of the infusion accordingly. Rate Lock Off: Permits the user to set the required flow rate, in ml/hr. The pump detects the volume of the syringe and calculates the duration of the infusion accordingly.

Technical Overview Syringe pumps are ideal for low-volume applications where accuracy is important. A syringe pump is often called a piston pump or syringe driver, as the fluid is moved by the syringe piston. The accuracy of the pump is determined in conjunction with the syringe used, and should only be used with syringes approved by the pump manufacturer. The driving mechanism is a lead screw, rotated either by a stepper motor or by a permanentmagnet motor with a gearbox. The T34™ Syringe Pump uses a permanent-magnet motor, which can deliver the same torque as a stepper motor, but from a much smaller unit, as it draws much less current than a stepper motor of comparable rating. Both of these factors are significant in a pump for which size and battery life are important. When testing a syringe pump at low rates, it is important to let the unit run long enough to take up the system backlash before attempting to measure volumetric accuracy. The T34™ Syringe Pump includes a Technician menu, which speeds up this process. Because the displacement rate is determined by the lead screw pitch and the rate of the optical shaft encoder pulses as well as the syringe data in the pump database, the need to adjust the device is eliminated.
Occlusion Detection in the T34™ Syringe Pump The T34™ Syringe Pump does not use a strain gauge to measure occlusion force. Instead, the motor current is monitored by a linear amplifier. The resulting voltage is roughly proportional to force. While this system is not as accurate as a strain gauge in a bridge configuration, it is adequate for the intended application of the pump. Variations in friction of the syringe affect the occlusion pressure. Therefore, it is important to use a new syringe when verifying performance. A syringe friction rapidly increases after only a few occlusion measurements.
Motor Control in the T34™ Syringe Pump Motor rotation is monitored by an optical shaft encoder and a rotating magnet. The microprocessor uses data from both to confirm the motor speed. The rotating magnet on the motor shaft operates a reed switch positioned just below the shaft end of the motor. A slotted disc on the end of the lead screw, together with an IR LED and photodiode, form a shaft encoder to monitor the lead screw position. Two more reed switches, one at each end of the lead screw, slow the motor as the actuator approaches the end stop (also referred to as the End of Travel).
T34TM Syringe Pump (3rd Edition) Technical Service Manual (Rev.02)

General Information
The motor can be stopped, started or reversed by means of an H-Bridge driving circuit.1 With a large syringe size and a high occlusion setting, the motor current can easily exceed 100 mA, so it is important that an alkaline battery be used. A zinc carbon-type battery cannot provide the high current required as occlusion occurs. As with most modern products, all functions are controlled by a microprocessor. The main crystal clock for the processor is checked against the RTC clock source to ensure correct timing. A watchdog timer is also employed to shut down the motor and keypad if the micro program stops executing. The motor speed is locked via the encoder to the checked crystal source and confirmed by the motor reed switch pulses. There is no provision for speed adjustment as there is no need for it. On power-up, the microprocessor carries out a self-test on most subsystems, including the motor and encoders.
Performance Verification There are a number of items that the microprocessor cannot test without human intervention. These are the display and LEDs, acoustic alarm, keypad matrix, syringe size potentiometer, collar micro switch, plunger micro switch and accuracy of occlusion detection. These items must be manually tested, by entering Technician mode and scrolling to the Main Self-Test menu, where several automated test routines allow rapid confirmation of all system alarms and functions.

H-Bridges are available as integrated circuits, or they can be built from discrete components.

2 Configuration and Calibration Batteries
The T34™ Syringe Pump has a lithium CR1220 3V battery on the motor PCB, which keeps the time and date data on the event log. The battery should be replaced every four years, and should be checked annually: To verify 1. Switch on the pump and wait for the main menu to appear 2. Remove 9V primary battery while pump is still on to trigger the back-up alarm system 3. Verify that back-up alarm system beeps for at least 3 minutes. It is also advised to replace battery if it is less than 3V (using voltmeter). This should only be checked when pump is open and the 3V battery is accessible. Otherwise, there is no need to open pump specifically for testing battery.
Battery Operation
The T34™ Syringe Pump operates on battery power. Note: Only use 9 V alkaline, IEC 6LR61 type. Do not use batteries marked 6LP3146 or 6LF22 with the T34™ Syringe Pump. 6LP3146 and 6LF22 batteries can cause issues with the operation of the syringe pump, as the physical construction and internal resistance of this type of battery are different to the 6LR61 battery. Issues arising from use of the 6LP3146 and 6LF22 batteries can include End Battery messages during Pre-Load, volume test fails, pressure test/calibration issues and reduced amount of infusions from a battery. Note: Verify that the battery is in good condition by pressing the setup or operation. Press the
key during program
key to display the battery status.
There are two battery alarm conditions: The pump warns that the battery is low before the End Battery alarm activates. When the battery is depleted, the pump ceases operation and the End Battery alarm is activated: If the battery runs out, End Battery appears on the display. The pump stops the infusion. The pump may shut down immediately.
Low Battery End Battery
From the End Battery state, the user cannot restart the pump until the battery is replaced with a new one.
