  • 1. PRESENTED BY- RAJANYA DEY NETAJI SUBHASH ENGINEERING COLLEGE
  • 2. A syringe pump is a small infusion pump (some include infuse and withdraw capability), used to gradually administers small amounts of fluid (with or without medication) to a patient or for use in chemical and biomedical research.
  • 3.  Infusion only pumps: -the syringe plunger is pushed forward by the motor to deliver the liquid.  Infusion /withdrawal pumps: -functions same as the infusion pump but at the end of the run,the motor reverses & the syrnge plunger moves in the opposite direction causing the syringe to fill again.
  • 4.  Push/Pull and continuous flow pumps: -Push/Pull pumps are a variation of the infusion withdrawal pump, except that the syringes are opposing each other.  High Pressure Pumps: -syringe pumps are controlled by a rotating screw thread driven by a motor, they will deliver a fixed amount of linear force. The amount of pressure that force will translate into is dependent on the diameter of the syringe. A small diameter syringe will generate a much higher pressure than a wide diameter syringe.  Low Flow Rate Pumps: -The more steps and the finer the threads, the less the plunger will move and the more smoothly it will move.
  • 5.  Syringe pump is designed for precise dosage of drugs and infusion fluids to the patient. It is intended for: • Intensive care units, • Cardio surgery units, • Pediatric units, • Operating theatres, • Ambulances. The pump is simple to operate, reliable and is of general application. It is suitable for various types of single-use syringes. BOLUS function enables quick and repeated delivery of bolus doses to the patient, with accurately established volume and within a specified infusion time. Pump can operate without connection to the mains. The pump is automatically supplied by the internal battery in cases, e. g. of mains failure. It also enables to continue the infusion when the patient is being transported. Simple casing, without any parts protruding from the front panel, facilitates maintenance and disinfection.
  • 6. FEATURES: FLOW RATE RANGE: 0.1-200ml/h(depending on the syringe capacity- up to 1200ml/hr) Syringe capacities: 5, 10, 20, 30/35, 50/60 CC. Bolus: Manual bolus: Rate 50-1200 ml/h (50 ml/h increments). Pressure modes: 2 modes available: variable or 3 pre-set levels - From 100 to 900mmHg, 50 mmHg increment.

  • 8.  The design and construction of syringe pumps must follow precisely documented processes.The equipment also must contain comprehensive self-test and fault- indication capabilities.  Electrical leakage to the patient is a significant concern.  Even though the pump is a patient-connected device, the connection is nonconductive, so it falls in the least- stringent category (type B).  Syringe pumps must be portable, since patients need to be mobile both within the hospital and at home. The devices must be battery powered, relatively small, and relatively lightweight.
  • 9. Syringe pumps are small pumps operated by driving a syringe via a very precise motor. Changing the syringe allows a wide range of flow rates on the same pump. They are used for infusion, infusion & withdrawal and continuous flow applications. In a syringe pump, fluid is held in the reservoir of a syringe, and a moveable piston controls fluid delivery. Syringe pumps are also useful for delivering IV medications over several minutes. While using the syringe pump the safety measures must be kept in check
