Intravenous fluid supply device

An intravenous fluid supply device, comprising:

• an extrusion means (A);
• and
• a control means (B),
• wherein the extrusion means (A) is structured such that:
• an infusion fluid set (11) is inserted in a space (5) of a body (1);
• a cam (16) engaged with a motor (15) via a shaft is slidably installed in a cam receiving space (20) so that a protruding portion (18) of a motor fixing plate (17) presses an elastic tube (33) when the motor (15) is activated;
• an extrusion means (A) is structured such that:
• a tension spring (27) is elastically installed between a pin (26) fixed to an upper surface of the body (1) and a pin (25) fixed to a cam housing (19) so that the cam housing (19) engaged with the same shaft (23), and the motor fixing plate (17) that fixes the motor (15) are interlockingly pivoted and turned, and
• wherein the control means (B) includes:
• an input means (200) that sets an extrusion repetition cycle of the motor (15) and a total injection amount;
• a detection means (300) structured such that a hall sensor (67) is attached to the motor fixing plate (17), a permanent magnet (22) is buried in the cam housing (19) in the corresponding position of the hall sensor (67), and a sound sensor (68) is mounted on a main part (6) of the body (1);
• a motor driving means (400) that activates the motor (15);
• a microcontroller (500) that controls the motor driving means (400) according to inputs made by the input means (200) and the detection means (300);
• and
• an LED lighting means (700) that enables checking on the flow of an infusion fluid according to the control of the microcontroller (500).
