Problems solved by technology

[0002] In the drip infusion, the current equipment used for drip infusion usually can only use the method of manual monitoring of the liquid level, and its disadvantage is that it takes up a lot of human resources and the efficiency is low
However, some devices that use the principle of sound and light to detect the level of drip infusion have poor anti-interference ability and are prone to false alarms in practical applications.

Embodiment Construction

[0016] Below in conjunction with accompanying drawing, content of the invention will be further described:

[0017] refer to figure 1 and figure 2 As shown, the capacitive drip liquid level monitoring and alarm device includes a measuring capacitor 3 installed on the outer wall of the infusion hose 1 connected to the inlet of the drip funnel 2 of the medical intravenous infusion tube, a measuring capacitor 3, and a capacitor measuring circuit 5 , single-chip microcomputer 6 and data wireless transmission circuit 7 are electrically connected in pairs in turn. The measuring capacitance 3 is a cylindrical capacitor with edge gaps, the cylindrical capacitor is surrounded on the outer wall of the infusion hose 1, the pole plate of the cylindrical capacitor is made of metal material and the height of the pole plate is no more than 3cm , the width of the edge gap is not more than 0.5mm. The measuring capacitor 3 is externally equipped with a grounded metal shield 8 . The capaci...

Abstract

Disclosed is a capacitor-type drip liquid level monitoring alarm device. The capacitor-type drip liquid level monitoring and alarm device comprises measurement capacitor which is additionally arranged on the outer wall of a transfusion tube communicated with the inlet of a drip chamber of a medical vein transfusion tube. Each two of the measurement capacitor, a capacitance measurement circuit, a single chip machine and a data wireless transmitting circuit are sequentially and electrically connected. The structure avoids the defects that occupation of manpower resource is large, efficiency is low and anti-interference ability is bad.

Description

technical field [0001] The invention belongs to the technical field of drip liquid level sensing devices, and in particular relates to a capacitive drip liquid level monitoring and alarm device, that is, a capacitive drip for monitoring the liquid level state in the infusion tube and outputting alarm information during intravenous drip infusion Liquid level monitoring and alarm device. Background technique [0002] During drip infusion, the equipment used for drip infusion can only adopt the method of manually monitoring the liquid level at present, and its disadvantage is that it takes up a lot of human resources and the efficiency is low. However, some devices that use the principle of sound and light to detect the drip infusion liquid level have poor anti-interference ability and are prone to false alarms in practical applications. Contents of the invention [0003] The object of the present invention provides a kind of capacitive drip liquid level monitoring and alarm...
