In one embodiment, described pulse signal generating circuit comprises: first comparator, and its reverse input end connects the output of phototriode; Second comparator, its inverting input connects the output of first comparator; Photoelectrical coupler connects the output of second comparator; Audion connects described photoelectrical coupler; Wherein, when not having drop between described phototriode and infrarede emitting diode, to pass, phototriode is received the Infrared and the conducting of infrarede emitting diode emission, the inverting input of first comparator is a low level, and the outfan of first comparator is a high level, thereby, the outfan of second comparator is a low level, make the luminous tube of photoelectrical coupler light, photosensitive tube conducting, the colelctor electrode output low level of described audion; When drop passes between described phototriode and the infrarede emitting diode, phototriode can not receive the Infrared of infrarede emitting diode emission and ends, the inverting input of first comparator is a high level, the outfan of first comparator is a low level, thereby the outfan of second comparator is a high level, makes the photosensitive tube of photoelectrical coupler end, the colelctor electrode output high level of described audion forms pulse signal.
In one embodiment, described siren is a buzzer.
In one embodiment, also comprise count display, show current counting.
This utility model efficiently solves the problem that needs medical personnel and family numbers of patients continuous care in the infusion process, make patient be able to good rest, also improved medical personnel's work efficiency, also avoid the probe-type alarm need contact medicinal liquid, cause hidden danger to cause the situation of wrong report with utilizing all kinds of other alarms of monitoring liquid level to be subjected to page wobble effects easily.
Description of drawings
Fig. 1 is the mounting structure figure of infusion alarm of the present utility model;
Fig. 2 is the electronic-circuit diagram of infusion alarm of the present utility model.
The specific embodiment
This utility model provides a kind of infusion alarm, is enclosed within on the stilligout, and Fig. 1 shows its structure, comprising:
One annular shell 10 is enclosed within on the stilligout 11, and this annular shell can be steel, and electronic circuit wherein is set, and this electronic circuit comprises:
A phototriode staggered relatively and an infrarede emitting diode, wherein, the drop in the stilligout passes between this phototriode and infrarede emitting diode;
Pulse signal generating circuit when a drop passes, produces a pulse signal between this phototriode and infrarede emitting diode;
Enumerator is connected to pulse signal generating circuit, counts according to pulse signal;
Decoder is connected to enumerator, and a current counting and a predetermined number are compared, and when current counting during more than or equal to predetermined number, sends an alarm signal.
On this shell 10, also comprise siren 12, be connected to decoder, report to the police according to alarm signal.According to an embodiment, this siren 12 is a buzzer.
On this shell, also comprise power module 13, such as a battery case.
In one implementation, also comprise count display 14 on this shell 10, such as the display of segment code type, to show current droplet counting.
With reference to figure 2, it shows electronic-circuit diagram of the present utility model.As described above, this electronic circuit comprises a phototriode staggered relatively and an infrarede emitting diode, pulse signal generating circuit, enumerator and decoder.Wherein pulse signal generating circuit further comprises: first comparator, and its reverse input end connects the output of phototriode; Second comparator, its inverting input connects the output of first comparator; Photoelectrical coupler connects the output of second comparator; Audion connects described photoelectrical coupler.The operation principle of this pulse signal generating circuit is as follows: wherein, when not having drop between described phototriode and infrarede emitting diode, to pass, phototriode is received the Infrared and the conducting of infrarede emitting diode emission, the inverting input of first comparator is a low level, and the outfan of first comparator is a high level, thereby, the outfan of second comparator is a low level, make the luminous tube of photoelectrical coupler light, photosensitive tube conducting, the colelctor electrode output low level of described audion; When drop passes between described phototriode and the infrarede emitting diode, phototriode can not receive the Infrared of infrarede emitting diode emission and ends, the inverting input of first comparator is a high level, the outfan of first comparator is a low level, thereby the outfan of second comparator is a high level, makes the photosensitive tube of photoelectrical coupler end, the colelctor electrode output high level of described audion forms pulse signal.
With reference to figure 2,, the drop drippage is arranged discontinuously just in the stilligout when patient begins transfusion.When not having drop to pass through between phototriode VT1 and the infrarede emitting diode VD1, phototriode VT1 receives infrarede emitting diode VD1 and penetrates the ground Infrared, phototriode VT1 conducting, the inverting input of the first comparator IC2-B are low level, outfan output high level.The high level of first comparator IC2-B output is added to the inverting input of the second comparator IC2-A, makes the outfan output low level of the second comparator IC2-A.So the light emitting diode in the photoelectrical coupler 4N35 is lighted, corresponding photosensitive tube conducting, also conducting of audion VT2, audion VT2 colelctor electrode output low level.In the time of between drop is by phototriode VT1 and infrarede emitting diode VD1, the infrared ray of infrarede emitting diode VD1 emission is blocked, and phototriode VT1 ends.The inverting input of the first comparator IC2-B is a high level, the outfan output low level.Low level is added to the inverting input of the second comparator IC2-A, makes the outfan output high level of the second comparator IC2-A.Photoelectrical coupler 4N35 ends, and audion VT2 also ends, audion VT2 colelctor electrode output high level.This high level only produces when drop passes between phototriode VT1 and the infrarede emitting diode VD1, therefore, because the time that drop passes is very of short duration, has just formed pulse signal waveform in the output of audion VT2 colelctor electrode.
This pulse signal is handled by enumerator IC3, decoder IC4 afterwards, forms alarm signal, realizes reporting to the police and counting.
In the embodiment shown in Figure 2, except the above-mentioned element of mentioning, also comprise the auxiliary element of resistance, electric capacity etc.These elements are to realize that circuit function is required, still, it is apparent that the layout of these auxiliary elements and parameter can be chosen as required, therefore do not do description here.
This utility model efficiently solves the problem that needs medical personnel and family numbers of patients continuous care in the infusion process, make patient be able to good rest, also improved medical personnel's work efficiency, also avoid the probe-type alarm need contact medicinal liquid, cause hidden danger to cause the situation of wrong report with utilizing all kinds of other alarms of monitoring liquid level to be subjected to page wobble effects easily.
