Embodiment Construction

[0013] Such as figure 1 As shown, a kind of alarm device capable of infusion of intravenous infusion liquid includes front and rear infusion tubes 7, 4 and an infusion device 2 connected between the two tubes, the front end of the front infusion tube and the liquid medicine in the hanging bottle Connected, the terminal of the back infusion tube is connected to the needle of the intravenous drip. A pair of opposite metal pole plates 3 are arranged radially on the outer circumference of the infusion set 2 to serve as capacitive sensors. The pair of metal pole plates are connected to the input end of a measurement control circuit 6 by wires, and the output end of the measurement control circuit is connected to the blocker by wires. 5. The blocker is set on the rear infusion tube 4. When the drop in the infusion set falls, the capacitance value between the metal plates 3 will be significantly changed. The measurement control circuit 6 captures the capacitance change and makes a ...

Abstract

The invention discloses a venous transfusion device capable of alarming and preventing blood return. The device comprises a front infusion tube, a rear infusion tube and an infusion apparatus which is connected between the front infusion tube and the rear infusion tube, the front end of the front infusion tube is communicated with liquid medicine in a drip-feeding bottle, and the final end of the rear infusion tube is connected with an intravenous drip needle head. The device is characterized in that a pair of face to face metal polar plates is arranged on the periphery of the infusion apparatus in a radial direction, the metal polar plates serve as a capacitance-type sensor, the pair of metal polar plates is connected with an input end of a measurement control circuit through a guide line, an output end of the measurement control circuit is connected with a blocker through the guide line, and the blocker is disposed on the rear infusion tube.

Description

technical field [0001] The invention relates to an infusion device which automatically blocks the infusion tube and sends out an alarm in time after the intravenous infusion of liquid is completed. Background technique [0002] Liquid intravenous infusion is also called "transfusion", "spot drip" and "intravenous drip". Currently commonly used infusion devices do not have alarm and blocking functions, and need an accompanying person to observe whether the liquid medicine in the medicine bottle is dripped at any time, and notify the medical staff to handle it. Otherwise it will cause bleeding. Contents of the invention [0003] The purpose of the present invention is to provide a device that can automatically block the infusion tube and send an alarm in time after the intravenous infusion is finished, so as to avoid the blood return phenomenon after the infusion when no one is accompanying, and improve the efficiency of medical care. [0004] To achieve the above object, ...
