Description
Technical field
This utility model belongs to technical field of medical instruments, particularly relates to a kind of automatic alarm for infusion being provided with time base circuit.
Background technology
At present, the core of infusion alarming is the triggering of reporting to the police, and the triggering of reporting to the police should occur in transfusion when completing, and can say and how detect the key problem that when having infused, infusion alarm will solve.
Mostly previous inventive principle is: what utilize photoelectric non-contact type detection medicine to drip is dynamic, and circuits for triggering work, loads onto optoelectronic device in the bottom of bottle or dropper surge flask place in other words, does not have produce the signal of telecommunication during liquid.But such invention obviously has a lot of problem: this device should be clipped on bottle or dropper, cumbersome when replacing liquid and bottle; Medicinal liquid bottle not of uniform size, and some is packed medicinal liquid, makes the installation versatility of this device become problem; The detection of working fluid is not very accurate, and rate of false alarm is higher.
Also having a kind of is in addition the principle applying gravity: no matter be what kind of liquid, the weight that final liquid has played rear remaining sack and bottle should be below a certain weight, such as 50g (one or two), as long as so find resolution to reach the LOAD CELLS of below 50g, then be aided with control circuit, just can quote alarm comparatively accurately.Still there is following problem: infusion bottle capacity is different, and weight is also different, and some is transfusion bag, and the disunity of such weight makes the setting of each alarm become loaded down with trivial details, increase the burden of medical personnel.
Visible, all there is the problems such as rate of false alarm is high, poor universality in alarm conventional at present, needs a kind of novel infusion alarm of research and development badly.
Summary of the invention
This utility model provides the automatic alarm for infusion being provided with time base circuit that a kind of structure is simple, easy to install, increase work efficiency for solving in known technology the technical problem that exists.
The technical scheme that this utility model is taked for the technical problem existed in solution known technology is: this autoalarm comprises infrared transmitter, infrared remote receiver, time base circuit and sound alarm module, infrared transmitter is arranged on the top of transfusion drip tube, infrared remote receiver is arranged on the top of transfusion drip tube, time base circuit is connected with infrared remote receiver, and audible alarm module is connected with time base circuit.
This utility model can also adopt following technical measures:
The concrete connection of time base circuit is: pin 2 and the pin 6 of chip NE556 connect together, and are connected with the anode of infrared receiving tube D1; Pin 3 is connected with electric capacity C1; Pin 4 is connected with the positive pole of 5 ~ 6V power supply by K switch 1; Pin 5 and pin 10 connect together and are connected with resistance R4; Pin 7 is directly connected with the negative pole of power supply; Pin 8 and pin 12 connect together, and are connected with electric capacity C2 one end with resistance R6; Pin 9 is connected with resistance R7 one end; Pin 11 is connected with electric capacity C3; Pin 14 and pin 4 are connected in the positive pole of 5 ~ 6V power supply by K switch 1.
The advantage that this utility model has and good effect are: highly versatile, and because the checkout gear of this alarm is arranged on the dropper of transfusion, and the size dimension of transfusion drip tube is generally fixing, and so different medicinal liquid and medicament all can use this alarm; Easy for installation, because the size of dropper is basically identical, directly alarm can be stuck in and drip on kettle, install, take down easy to operate; Detect accurately, because infrared detection drop technique is with the obvious advantage, have higher accuracy and lower rate of false alarm, and detection of electrons has higher response speed; Cost is lower, because time base circuit, audible alarm module device used are cheap, can reach lower development cost.
Accompanying drawing explanation
Fig. 1 is a kind of structural representation being provided with the automatic alarm for infusion of time base circuit that this utility model provides;
Fig. 2 is the circuit diagram of time base circuit and sound alarm module.
In figure: 1, transfusion drip tube; 2, infrared transmitter; 3, infrared remote receiver; 4, time base circuit; 5, audible alarm module.
Detailed description of the invention
For summary of the invention of the present utility model, Characteristic can be understood further, hereby exemplify following examples, and coordinate accompanying drawing to be described in detail as follows:
Fig. 1 is a kind of structural representation being provided with the automatic alarm for infusion of time base circuit that this utility model provides.This autoalarm comprises infrared transmitter 2, infrared remote receiver 3, time base circuit 4 and sound alarm module 5, infrared transmitter 2 is arranged on the top of transfusion drip tube 1, infrared remote receiver 3 is arranged on the top of transfusion drip tube 1, time base circuit 4 is connected with infrared remote receiver 3, and audible alarm module 5 is connected with time base circuit 4.
This utility model can also adopt following technical measures:
The concrete connection of time base circuit 4 is: pin 2 and the pin 6 of chip NE556 connect together, and are connected with the anode of infrared receiving tube D1; Pin 3 is connected with electric capacity C1; Pin 4 is connected with the positive pole of 5 ~ 6V power supply by K switch 1; Pin 5 and pin 10 connect together and are connected with resistance R4; Pin 7 is directly connected with the negative pole of power supply; Pin 8 and pin 12 connect together, and are connected with electric capacity C2 one end with resistance R6; Pin 9 is connected with resistance R7 one end; Pin 11 is connected with electric capacity C3; Pin 14 and pin 4 are connected in the positive pole of 5 ~ 6V power supply by K switch 1.
Time base circuit 4 produces timing and time delayed signal, produces the timing of 5S, and when after the low 5S of dripless, time base circuit 4 toggle sound alarm module 5, audible alarm module 5 is play music and produced alarm signal.
The advantage that this utility model has and good effect are: highly versatile, and because the checkout gear of this alarm is arranged on the dropper of transfusion, and the size dimension of transfusion drip tube is generally fixing, and so different medicinal liquid and medicament all can use this alarm; Easy for installation, because the size of dropper is basically identical, directly alarm can be stuck in and drip on kettle, install, take down easy to operate; Detect accurately, because infrared detection drop technique is with the obvious advantage, have higher accuracy and lower rate of false alarm, and detection of electrons has higher response speed; Cost is lower, because time base circuit, audible alarm module device used are cheap, can reach lower development cost.
