In general hospital, often visible doctor does fluid infusions such as normal saline solution or glucose solution to the patient, and because the some drop bottle finite capacity of this class solution, in case promptly need change or finish the fluid infusion behavior with finishing.For the monitoring of patient's fluid infusion behavior, generally itself serve as at present by patient family members, nursing staff or patient.The artificial nurse mode of this kind is for the caregiver, often form greatest psychological burden and physical load, especially when nursing the late into the night, need to observe again and again in order to note drop solution whether to use up, cause the caregiver usually to lie awake all night, cause the load on spirit, the muscle power such as patient, family members or nursing staff.Therefore, how providing the omnidistance monitoring point of a kind of caregiver of assistance means whether drop bottle solution is used up, to alleviate caregiver's burden, is the task of top priority, and more society is found pleasure in and seen.

In view of the problem described in the preceding paragraph, the inventor of the present utility model development and Design of actively concentrating on studies, release a kind of fluid infusion eventually and assist care device with electronics, it mainly inserts from putting the drop bottle bottle stopper with an induction needle tubing, whether has reached lower limit in order to solution in the drop bottle of monitoring point.This induction needle tubing is connected with a circuit for alarming, sense when a drop bottle solution will use up at the induction needle tubing, the IC agitator of mat circuit for alarming is exported a pulse immediately, make a buzzer and LED action, mat and cooperate blinking light to inform caregiver or patient with bleep, and supervise it to change some drop bottle or end fluid infusion, its main purpose is:

Assist care device by fluid infusion of the present utility model with electronics, assist caregiver or patient itself to come drop bottle interior solution in monitoring point whether to use up, and arouse the caregiver or the patient notes, thereby alleviate patient family members and medical personnel's nurse pressure and work load with its acousto-optic warning signal.

About structure content of the present utility model and claimed emphasis, special embodiment and the accompanying drawing of cooperating provides more detailed description.

Fig. 1 is the circuit diagram of this utility model circuit for alarming.

Fig. 2 is a this utility model induction needle tubing and the situation that cooperates of circuit for alarming.

Fig. 3 be this utility model with the some drop bottle cooperate situation (enforcement illustration).

See also shown in Figure 2ly, the figure invading the exterior is understood the auxiliary care device of drop electronics of the present utility model, and it mainly comprises;

One induction needle tubing 10, it inserts one again and has in the needle tubing 13 of two air-vents 131,141 after mainly passing an insulator 12 with an interior pin 11, and wherein, because insulator 12 is set, pin 11 is not same conductor with needle tubing 13 in making;

One circuit for alarming 20 as shown in Figure 2, is its core with an IC agitator 21 mainly, and this IC agitator 21 has:

Power pin 211 directly is connected to the Vcc power end;

Ground connection pin 212, directly ground connection;

Trigger pin 213, connect a resistance 22 and the Vcc power end and that arrives triggers contact A, and this triggering pin 213 connects the colelctor electrode of a transistor 23 simultaneously, and the grounded emitter of this transistor 23, base stage connect a current-limiting resistance 24 and arrive another triggering contact B;

Output connecting pin 214 connects a buzzer 25 to earth terminal, and this buzzer 25 and in parallel with a LED.

As the auxiliary care device of above-mentioned drop electronics, its circuit for alarming 20 mats trigger contact A and B and respectively with the needle tubing 13 of induction needle tubing 10 and in pin 11 be connected.Therefore, assisting the induction needle tubing 10 of care device when this drop electronics inserts in the some drop bottle 30 that fills saline solution or glucose solution (as shown in Figure 3), because putting drop bottle solution is a kind of electric conductor, and because of the needle tubing 13 and the interior pin 11 of induction needle tubing 10 all contacts with this solution simultaneously, so, at this moment, will be between the contact terminal A of circuit for alarming 20 and the B because of such solution short circuit.So the voltage of Vcc power end just makes transistor 23 triggering and conducting via current-limiting resistance 24, the triggering pin 213 of IC agitator 21 is as ground connection, and can't trigger IC output connecting pin 214 so that buzzer 25 and LED action.When solution in the drop bottle 30 reduces gradually because of injection, as long as the solution water level is reduced to the L water level once, promptly because the needle tubing 13 of induction needle tubing 10 and in there is no solution between the pin 11 can be for conduction, make to form open-circuit condition between the triggering contact A of circuit for alarming 20 and the B.So, make this transistor 23 be cut-off state because of the base stage of transistor 23 can't obtain trigger voltage.At this moment, the triggering pin 213 of IC agitator 21 is promptly because of making current potential raise by resistance 22, cause IC agitator 21 to be triggered, and by its output connecting pin 214 outputs one pulse to supply with buzzer 25 and LED, make buzzer 25 and LED with the frequency of oscillation of this pulse the serge serge make a sound and be the flicker shape, use and inform that solution will be used up in people's drop bottle, and urge people will put drop bottle as early as possible and change or withdraw, so reach the purpose of assisting patient, patient family members or medical personnel monitoring point drop bottle.

From the above mentioned as can be known, main effect of the present utility model is that the detection of mat induction needle tubing monitors, so that when solution is about to use up in a drop bottle, make IC agitator trigger action, buzzer serge serge is made a sound, the LED flash of light and make, to arouse patient, family members or medical personnel's attention, avoid causing the medical treatment injury, and alleviate the nurse load;

Because the needle tubing of this utility model induction needle tubing is provided with two air-vents, make air be able in the inlet point drop bottle, make the interior solution of some drop bottle to flow out more swimmingly by this two air-vent, be another effect of the present utility model.
