As shown in Figure 1, photoelectric liquid level sensor 7 uses commercially available GDY-200 type photoelectric liquid level sensor, it is by a hair Electric switch 703 built in optical diode 701, a photoreceiver 702 and one forms.Wherein, light emitting diode 701 is embedded in solid It is scheduled on the first clamp 601 of locating clip 6, the embedding peace of photoreceiver 702 is fixed on the second clamp 602 of locating clip 6, and is sent out Optical diode 701 is corresponding with photoreceiver 702.

In Fig. 2, light emitting diode 701 is connected electrically between the positive and negative electrode of DC power supply 2, photoreceiver 702 and electricity Air cock 703 is electrically connected, and alarm 3, warning lamp 4 are connected electrically in direct current through the electric switch 703 of photoelectric liquid level sensor 7 Between the positive and negative electrode in source 2.

When the utility model is used, being clamped in locating clip 6 close on the perfusion tube of infusion bottle, photoelectric level is utilized In two kinds of extended medias reflection and refraction principle occur for the infrared ray that the light emitting diode 701 of sensor 7 is emitted, When perfusion tube lacks liquid, photoreceiver 702 receives the light of the sending of light emitting diode 701 and drives and built-in electrically open 703 are closed, to connect the circuit for being connected to alarm 3, warning lamp 4 between 2 positive and negative electrode of DC power supply, 3 sounding of alarm is alert Show that lamp 4 shines, medical staff is reminded to replace medical fluid in time.

Locating clip generates skidding when clamping perfusion tube in order to prevent, as shown in Figure 1, in the first clamp 601 of locating clip 6 Inside is equipped with the first anti-slip layer 801, is equipped with the second anti-slip layer 802, the first anti-slip layer 801 and the in the inside of the second clamp 602 Two anti-slip layers 802 are corresponding and are respectively in arc-shaped.

In order to enable perfusion tube to clamp perfusion tube in time when lacking liquid, as shown in Figure 1, the utility model further includes one Electromagnetic clamp switch 9.

In Fig. 1, electromagnetic clamp switch 9 is the iron axis that spread out by a upper housing 901, a lower case 902, an electromagnet 903, one 904 and one pipe clamp head 907 form.

As shown in Figure 1, being threadedly coupled between upper housing 901 and lower case 902.

In Fig. 1, a cavity 9011 is opened up in the inside of upper housing 901, electromagnet 903 is fixed in cavity 9011, It is made of conventional electromagnetic coil 9031 and iron core 9032.

As shown in Figure 1, coaxial line perforation opens up an axis hole 9021 and a pressure regulating cavity 9022 in lower case 902, in lower casing Vertical axis opens up a lumen 9023 on body 902, is opened up on the side chamber wall of lumen 9023 with one through notch 9024.Spread out iron axis 904 one end passes through pressure regulating cavity 9022, axis hole 9021 extends to outside lower case 902, and corresponding with electromagnet 903, and spread out iron The other end of axis 904 is extended in lumen 9023 and is threadedly coupled with pipe clamp head 907, which has a pipe clamp chamber 9071.It is threadedly coupled an adjusting block 906 at the middle part for the iron axis 904 that spreads out, between the bottom of chamber and adjusting block 906 of pressure regulating cavity 9022 Spread out and is set with a pressure spring 905 on iron axis 904.

In Fig. 2, the electromagnetic coil 9031 of electromagnet 903 is connected electrically in through the electric switch 603 of photoelectric liquid level sensor 6 Between the positive and negative electrode of DC power supply 2.

When the utility model is used, the perfusion tube that will be far from infusion bottle passes through and is entered in lumen 9023 by notch 9024, And perfusion tube is placed in the pipe clamp chamber 9071 of pipe clamp head 907.When perfusion tube lacks liquid, photoreceiver 702 is received Built-in electric switch 703 is driven to the light that light emitting diode 701 issues, to be connected to DC power supply 2 positive and negative to connect The circuit of the electromagnetic coil 9031 of electromagnet 903 between pole, electromagnetic coil 9031 generate magnetic force and magnetize iron core 9032, electricity Magnet 903 overcomes 905 active force of pressure spring to be attracted the iron axis 904 that spreads out, and the iron axis 904 that spreads out drives pipe clamp head 907 to be axially moved, makes pipe Dislocation is generated between collet 907 and the lumen of lower case 902 9023, the perfusion tube in pipe clamp chamber 9071 is squeezed and clamps, To prevent the fluid in perfusion tube from continuing to output；For electromagnetic coil 9031 in power loss, electromagnet 903 is no longer attracted the iron that spreads out Axis 904, the iron axis 904 that spreads out drive pipe clamp chamber 9071 to reset under the action of pressure spring 905, and perfusion tube can take out.

Spread out in order to prevent iron axis 904 end abjection, in Fig. 1, in the iron axis 904 that spreads out extended to outside lower case 902 A limited block 908 is fixedly connected on one end.

In order to can smoothly enter into 9023 inside of lumen conducive to perfusion tube and prevent perfusion tube from deviating from from lumen 9023, such as Fig. 1 It is shown, by notch 9024 by outside to tapered in lumen.

In order to prevent before infusion in perfusion tube without fluid when, alarm 3 and warning lamp 4 carry out false alarm prompt, such as Fig. 1 It is shown, a switch 5 is embedded on box body 1.In Fig. 2, switch 5 is serially connected in the anode and photoelectric liquid level sensor 6 of DC power supply 2 Electric switch 603 between.The electric switch 603 for controlling photoelectric liquid level sensor 6 when not being infused by switch 5 is disconnected Road.

The utility model have the advantages that it is easy to operate, meanwhile, the utility model use photoelectric liquid level sensor as Control element, therefore product cost is low, warning sensitivity is high.
