The specific embodiment

Below in conjunction with accompanying drawing, this utility model is further described by embodiment:

With reference to figure 1, Fig. 2 and Fig. 3, the multi-functional drop autoalarm of this utility model, comprise fixture and be arranged on automatic alarm control circuit on this fixture, this automatic alarm control circuit is made up of power module A, detection module B, micro controller module C, light alarm module D, audible alarm module E, test module H; Wherein power module is to provide normal working power to automatic alarm control circuit, control by on and off switch, micro controller module C provides working control signal to detection module B, and detection module B is transferred to micro controller module C with the signal variation, and the result that micro controller module C changes according to signal determines whether that output signal control sound alarm module E and light alarm module D send warning; Test module H is used for detecting the reliable operation performance of this product at the beginning of the work of this Multifunction drop autoalarm.

This Multifunction drop autoalarm, its audible alarm module E is in series by a switch and buzzer.When confirming not need the audible alarm function, it can be closed and do not influence other warning function.The design of this hommization considers to some extent, for example: with other ward mate's rests of ward the time; When transfusion patient needs peace and quiet, when the serious symptom isolation room; Having under the situations such as the special messenger guards, can suspend and use this function.

This Multifunction drop autoalarm, its automatic alarm control circuit can be provided with work indicating module F.

This Multifunction drop autoalarm, this automatic alarm control circuit can be provided with output control module G, and this output control module G is made up of a light Rhizoma Nelumbinis device or a relay.Its effect is can excellent interface be arranged with the external world when reporting to the police, and in the zone of original berth call function, with its output switch and berth switch in parallel, just can realize that manual simulation berth switch key calling medical personnel handle.Also can connect with external worlds such as lamp, speakers.Simultaneously, this function not the time spent to other work of whole alarm without any influence.So easy to use, hommization is big characteristics of the multi-functional drop alarm of this utility model.

This Multifunction drop autoalarm, power circuit is connected earlier with resistance R 7 by LED 1, be parallel to both ends of power with capacitor C 1, C2 again, and total power switch K1 forms.When total power switch K1 is closed, work indication LED 1 Chang Liang.When LED 1 does not work or is dark, expression power source voltage deficiency, this changes power supply.

Infraluminescence pipe D1 and fixed resistance R1, adjustable resistance R2 are connected on the two ends of power supply, regulate the electric current that R2 can control the infraluminescence pipe of flowing through, thus the control infra-red intensity.Infrared receiving tube T1 one end is connected with positive source, and the other end links to each other with resistance R 3, audion T2 base stage.Audion T2 colelctor electrode and resistance R 4 are connected on the two ends of power supply, form amplifying circuit, the variable signal that infrared receiving tube T1 is received infraluminescence pipe D1 amplifies, the microprocessor U1 that is transferred in the microcontroller handles, and the microprocessor U1 in the microcontroller is provided with lower limit analysis according to being provided with on the toggle switch K under the upper limit and the toggle switch K.After detecting amount of droplets in the unit interval and exceeding this bound scope, the 5th, 8,9 feet of the microprocessor U1 in microcontroller output pulse high level.Resistance R 6 and LED 2 are connected between microcontroller U1 the 5th foot and the electric current negative pole.When the 5th foot of the microprocessor U1 in the microcontroller was exported pulse high level, the caution of LED 2 flickers promptly carrying out light was reported to the police.

K switch 2 and capacitor C 3, buzzer 4 are connected between the 8th foot and power cathode of the microprocessor U1 in the microcontroller.When K switch 2 was closed, buzzer 4 will send " too ... " chimes of doom.When not needing audible alarm, cut-off switch K2, buzzer 4 just can not send " too ... " chimes of doom.One end of resistance R 5 and light Rhizoma Nelumbinis device 15 is connected between microprocessor U1 the 9th foot and electric current negative pole in the microcontroller.When the output of microprocessor U1 the 9th foot in microcontroller pulse high level, the other end of light Rhizoma Nelumbinis device 15 will form path and open circuit, thereby simulate artificial on-off control.

When detecting amount of droplets in the unit interval in this bound scope the time, the 5th, 8, the 9 feet output pulses low of the microprocessor U1 in the microcontroller, foregoing circuit will not worked.

At the beginning of work, with Test Switchboard K3 closure, at this moment, the microprocessor U1 in the microcontroller is from the variable signal of the 10th foot.Change signal once, and then the 5th, 8 feet of the microprocessor U1 in the microcontroller are exported pulse high level once, and LED 2 will dodge once, buzzer 4 will ring once, and expression detects a drop.See droplets fall and detect the droplets fall situation when identical when naked eyes, represent that this device performance is normal.Test Switchboard K3 is disconnected, can enter normal operating conditions.

This Multifunction drop autoalarm is provided with the hook button at the top of fixture.Its fixture can directly be fixed on the minim pipette, and a lanyard that can be locked in fixture by the hook button can also be set to be on the safe side.

When using this utility model, horse Fei Shi tube portion in the tube for transfusion is embedded in the multi-functional drop alarm of this utility model (as shown in Figure 1).When drop drips through the infrared detection district, owing to being subjected to the interference of drop, infrared ray produces scattering, and the level of infrared receiving terminal changes.The signal that changes is handled to micro controller module, thereby detects the quantity of certain period drop, and simultaneously, microprocessor judges that according to the parameter that upper limiting frequency switch and lower frequency limit switch are set the quantity of drop is whether in this scope.If overflow this scope, microprocessor just makes its work to light alarm module, audible alarm module, output control module output services signal, thereby reaches the purpose of automatic warning.

This utility model also can be used on other industry detecting oil droplet or whether other liquid drips off, drip is too fast, mistake is slow or situation such as obstruction.
