Description Of Syringe Pump

  • Introduction to the use of Injection Pump Machine:

    1 Clinical application of syringe pump When the clinically used drugs must be injected intravenously, and the dosage must be very accurate, the total amount must be small, and the delivery rate needs to be slow or constant for a long time, a syringe pump should be used. To achieve this goal.

    2 The structure and principle of the injection pump The injection pump is composed of a stepper motor and its driver, a screw rod and a bracket, etc. It has a reciprocating screw rod and nut, so it is also called a screw pump. The nut is connected to the piston of the syringe, and the syringe is filled with liquid medicine.

    The single-chip microcomputer system sends out control pulses to make the stepping motor rotate. The stepping motor drives the screw rod to turn the rotary motion into linear motion, pushes the piston of the syringe for injection and infusion, and injects the liquid medicine in the syringe into the human body. By setting the rotation speed of the screw, the advancing speed of the syringe needle can be adjusted to adjust the dose of the drug given (the administration speed is 0.1-99.9 nd_/h).

    3 Syringe pump setting and conversion method Since the measurement unit of any syringe pump is set in milliliters per hour, the amount and speed required for clinical use are often ·ksI1/min. ~ mg/mi~ etc. This conversion process requires medical staff to perform conversion. The specific conversion method is as follows.
