In the present embodiment, electromagnetic drive mechanism 4 comprises: electromagnet coil 7, have cylindrical cavity in the electromagnet coil 7, and its intracavity slides up and down and is connected with moving core 6, moving core 6 is fixedly connected with electric magnet slide bar 5, below the moving core 6, electric magnet slide bar 5 bottoms are with back-moving spring 8.
Tube for transfusion locking mechanism 17 upper side walls have electric magnet slide bar through hole 12, lower wall has handle through hole 14, locking slide bar 13 is housed in the tube for transfusion locking mechanism 17, locking slide bar 13 upper ends have elastic claw 11, the lower end has reseting handle 15, elastic claw 11 passes electric magnet slide bar through hole 12, reseting handle 15 passes handle through hole 14, and locking slide bar 13 rear ends are with locking spring 16.
Control circuit is made up of bubble observation circuit, signal amplification circuit, bubble lock circuit, sound light alarming circuit etc. in the present embodiment.Use of the present utility model does not change original infusion model and method, adopt infrared detection control device contactless, no any pollution, this utility model does not change original tube for transfusion route and transparent visual effect after installing, can not influence range estimation monitors, the bubble blocking-up of control tube for transfusion that can high reliability has reached reliable, convenient and safe transfusion purpose.
Bubble observation circuit in the present embodiment, as shown in Figure 5, constitute with receiving circuit by the infrared ray emission that with phaselocked loop decoding integrated circuit KA567 is the center, phaselocked loop decoder KA567 characteristics such as to have noise suppressed, narrow passband, frequency response range be 1～500KHz, be not subjected to that glitch disturbs, stable centers frequency and passband central frequency are adjustable wherein, so this device has very high reliability and noiseproof feature; When the signal frequency and 5 of its 3 foot input, when reference frequency signal that 6 oscillation networks that foot connects produce is consistent, 8 foot level are just by high step-down, and other circuit is controlled in the level variation thus.Infrared ray emission, receiving device adopt two TCRT1000, single TCRT1000 is an inner integrated infrared light emitting diode and an infrared receiver diode, adopt the single-row straight cutting of 4 pins to deceive Plastic Package, with the receiving tube in two TCRT1000 and two resistance R 5, R6, constituted two position infrared reflection formulas, detected the bridge circuit of function admirable, it is the key component of testing circuit.5 feet output 38KHz (parameter of the vibration timing element RC that 5,6 feet are external, the mid frequency f of decision internal voltage controlled oscillator VCO by KA567

26) ≈ 1Hz), electronic buzzer B rings and handles relevant matters with the prompting medical personnel simultaneously, simultaneously, reseting handle 15 can be pushed away to the right, treat that they are when handle through hole 14 right-hand members, elastic claw 11 pops up and enters in the electric magnet slide bar through hole 12, and locking spring 16 is compacted, makes elastic claw 11 left side walls withstand on electric magnet slide bar through hole 12 inner left wall.Button K2 is a SR 18, and bubble disposes in tube for transfusion, after 17 reduction of tube for transfusion locking mechanism, presses SR 18 one time, and system enters alert status again.Capacitor C 9, C13 and C14 can avoid on and off switch 19 (K1) to connect and disturb the misoperation of generation in the circuit, and green LED LED1 is a power supply indicator 20.
The whole low power dissipation design that adopts of this utility model, when alert status, quiescent current is 12 milliamperes, the action of warning transient electromagnetic ferrum, the circuit total current is about 70 milliamperes, and alarm current afterwards has only 15 milliamperes, so this utility model can adopt battery powered fully.Owing to do not need ac power supply, saved exchange conversion, rectification, filtering and mu balanced circuit, both brought the safety of electricity consumption, have device miniaturization again, advantage such as portable band, cost are low, easy to install.This utility model can be placed on arbitrary position under the Murphy type burette, when having bubble to pass through that test point just can be reported to the police when (comprising micro bubble) immediately in the tube for transfusion and blocking-up automatically, realized relying on warning device to substitute the function of artificial naked eyes monitoring, thereby removed patient and entourage's mental burden, nursing staff's operating pressure and mental pressure have been alleviated, reduce nursing staff's labor intensity, improved work efficiency and service quality.
The function of work process of the present utility model and realization is:
1, accurately, reliable detection performance.By infrared ray emission and the bridge circuit that receiving integrate circuit TCRT1000 constitutes, be the core circuit that bubble has or not detection in the tube for transfusion.Bridge circuit matches with the differential amplifier circuit that thereafter integrated transporting discharging TL082 constitutes, and can realize following function:
(1), when all not having any object before two reflection type infrared pick off TCRT1000 and block, system is in alert status.
(2), when having object to block before two pick offs simultaneously, system still is in alert status, so just makes that the installation of two pick offs is very convenient, both can be over against the place ahead, again can homonymy or the heteropleural face install, can not walking about or blocking of other object and misoperation because of personnel before the device.
(3), in the normal infusion process, in the tube for transfusion during no bubble, the output of bridge circuit no signal, circuit is failure to actuate.
(4), in the infusion process, when a pick off that is positioned at top or the place ahead, in case detected bubble, or when bubble (as bubble long or transfusion finish) is all arranged before two pick offs, electric magnet moves immediately, lock tube for transfusion, the blocking-up bubble makes it can not enter human body, carries out sound and light alarm simultaneously.
2, use phaselocked loop decoding integrated circuit KA567, finish single audio frequency decoding control task, make this utility model working stability, reliable, capacity of resisting disturbance is strong, can not cause misoperation because of transfusion site surrounding light, daytime or variations such as night, lighting situation.Capacitor C 9, C13, C14 can eliminate the misoperation that power connection moment or other interference cause, and have also increased reliability.
In case in 3 tube for transfusions bubble is arranged, electric magnet moves immediately, block the descending of bubble.During the electric magnet action, power supply will provide bigger electric current, still, just energising in short-term of electric magnet in this utility model, blocking-up is just kept by tube for transfusion locking mechanism 17 in electric magnet action back.
4, the power supply of sound light alarming circuit also has only when in the tube for transfusion bubble being arranged, and just connect by controllable silicon SCR control and report to the police, and the complete machine electric current only increases several milliamperes when reporting to the police, and has therefore also saved energy consumption.
5, after bubble disposes in the tube for transfusion, do not need the powered-down main switch, only need click SR 18, and tube for transfusion locking mechanism 17 is resetted, circuit enters alert status again.
6, in sum, circuitry designs except that detection control with high accuracy, reliability and warning characteristic, has taken into full account to cut down the consumption of energy, so that utilize battery power.So make the utlity model has that microminiaturization, cost are low, installation, characteristic such as esy to use, safe and reliable, can realize relying on this utility model to replace the work of artificial frequent monitoring and manual locking fully, removed the stress of hospitalized patients, reduced labor intensity, avoided because of postponing the generation that nursing causes malpractice.
