Described speed detect to adopt optical means to detect principle, and dropper is placed on the centre of detecting with the flute profile optocoupler, makes receiving terminal not receive light and produces high level twice, only can direct projection pass at drop middle part light, makes the receiving terminal output low level.

Described cutout testing circuit and bubble detect adopt infrared emission-reception to pipe as detection means, be installed in the tube for transfusion both sides respectively, medicinal liquid dripped between infraluminescence pipe and phototriode, cause change in optical signal, make the output voltage of phototriode change, after the IC358 operational amplifier carries out the signal amplification, be input to single-chip microcomputer and detect.

Described drive circuit adopts motor H type drive circuit, when IN1 is a high level, when IN2 was low level, audion Q1, Q4, Q5 managed conducting, and audion Q2, Q3, Q6 pipe end, motor just changes, when IN1 is a low level, when IN2 was high level, audion Q1, Q4, Q5 pipe ended, audion Q2, Q3, Q6 manage conducting, the motor counter-rotating.

Described Single-chip Controlling program mainly is made up of parameter setting, an amount setting, inquiry, key scan, urgent call, the setting of this plane No., and single-chip microcomputer is connected with cut-off equipment with the form of bus, and adopts the 232C serial communication.

Described signal drives to receive and is realized by the serial received interrupt service routine.

By adopting the aforementioned techniques scheme, the beneficial effects of the utility model are: this transfusion automatic monitoring alarm service system adopts photoelectric detecting technology, the drop of infusing is carried out non-contact detection realize dripping the speed detection, the management of employing single-chip microcomputer, can manually be provided with or drip speed, dropping liquid amount by the main frame setting, parameter is set can preserves, can inquire about, the cut-off equipment that is made of dc motor dams automatically when cutout or bubble occurring in the tube for transfusion and calls out medical personnel's disposal of coming.

The specific embodiment

Further specify this utility model below in conjunction with the drawings and specific embodiments.

Shown in Fig. 1, Fig. 2, Fig. 3 A, Fig. 3 B, a kind of transfusion automatic monitoring alarm system, comprise single chip machine controlling circuit, LCM display module, keyboard circuit, drip fast detection, telecommunication, cut-off equipment, described cut-off equipment connection cutout detects, bubble detects, signal drives reception, drive circuit.

Dripping the speed detection is the core of whole system, and accuracy of detection is to weigh a most important index of system accuracy, so just can the patient be faced a danger because a speed is unusual.For security consideration, when dripping speed, detection can not make former sebific duct breakage, otherwise will cause severe infections and influence the patient transfusion, therefore when dripping speed, detection to use non-contacting mode, drip speed and detect employing optical means detection principle, according to the light refraction principle, light will produce reflection and refraction at interface when the different medium of penetration density.Dropper is placed on the centre of detecting with the flute profile optocoupler, in testing process, drop is nearly ellipticity and does accelerated motion downwards and pass through the grooved optocoupler, because the surface of drop is a curved surface, produce twice high level so the first half and Lower Half with light two these refractions, make receiving terminal not receive light, only can direct projection pass at drop middle part light, make the receiving terminal output low level, thereby realize tally function.

Described cutout testing circuit and bubble detect adopt infrared emission-reception to pipe as detection means, drop to transfusion carries out non-contact detection, both satisfied safety and health request, the cutout testing circuit is installed in the tube for transfusion both sides respectively, medicinal liquid dripped between infraluminescence pipe and phototriode, cause change in optical signal, make the output voltage of phototriode change, after the IC358 operational amplifier carries out the signal amplification, being input to single-chip microcomputer detects, if in the nominal time, do not detect this signal, just can conclude the tube for transfusion interrupt flow, the operation principle of bubble detection circuit is identical with the cutout testing circuit, only be mounted in the position difference of tube for transfusion, when the medicinal liquid consecutive hours of tube for transfusion, the stabilizing output level of photosensitive tube, the appearance of bubble will cause that the output level of phototriode changes.

As shown in Figure 4, the Single-chip Controlling program is mainly by the parameter setting, the amount of dripping is provided with, inquiry, key scan, urgent call, this plane No. is provided with composition, described single-chip microcomputer is connected with cut-off equipment with the form of bus, and employing 232C serial communication, baud rate is provided with by timing/register 1, system clock is 11.0592MHZ, TL1=TH1=0F4H, warning message comprises 3 these machines of byte coding and 1 byte warning message sign indicating number (representing respectively dams reports to the police and the emergency alarm calling), the realization that Chinese shows, then be to adopt the smart display apparatus module of graphical dots configuration liquid, corresponding Chinese lattice information required input module according to sequential by single-chip microcomputer.

As shown in Figure 5, described signal driving receives by the serial received interrupt service routine and realizes, the system break program comprises external interrupt INT0, INT1, serial interruption three partly, and external interrupt 0 is used for finishing a speed and detects, when detected speed equates with default value, do not drip velocity modulation and put in order; When both differed big, it is whole that motor drips velocity modulation automatically, when adjusting to error less than 10% the time, then thinks and satisfied requirement of system design, no longer drips velocity modulation and put in order.External interrupt 1 is used for bubble and detects, stops and detect and detection of end.When taking place when unusual, the motor automatic-diversion closure also sends alarm calls information to main frame, and serial is interrupted being used to receive main frame to the set parameter of this machine.

More than show and described ultimate principle of the present utility model and principal character and advantage thereof; the technical staff of the industry should understand; this utility model is not restricted to the described embodiments; that describes in the foregoing description and the explanation just illustrates principle of the present utility model; under the prerequisite that does not break away from this utility model spirit and scope; this utility model also has various changes and modifications; these changes and improvements all fall in claimed this utility model scope, and the claimed scope of this utility model is defined by appending claims and equivalent thereof.
