Also comprise LED display, described LED display connection timer.
Described infrared sensor adopts E3F-5DN1E3F-5L correlation type infrared sensor.
Described single-chip microcomputer is 51 single-chip microcomputers.
Described alarm comprises bi-colour LED and buzzer, and described bi-colour LED is connected single-chip microcomputer respectively with buzzer.
Also comprise reset circuit and the SR being connected reset circuit, described reset circuit connects single-chip microcomputer.
Compared with prior art, this utility model has the following advantages:
1, this utility model device scope of application is wide, and inclined type arranges that accuracy of judgement is reliable, goes for the detection of all kinds infusion bottle and all kinds medicinal liquid.Wherein this device is installed in the Mo Feisi dropper of infusion bottle, therefore not by the impact of infusion bottle, goes for various infusion bottle.
2, this utility model installation cost is low, and power consumption is few, and simple structure has effectively saved the manufacturing cost of infusion alarm, and the low power consumption of 51 single-chip microcomputers also energy savings can reduce use cost, is conducive to a large amount of penetration and promotion.
3, this utility model device volume is little, and it is convenient, easy to use to place.
4, this utility model device arranges wireless transmitter, can notify nurse in time, changes the medicine bottle used up from the very first time.
5, this utility model device is provided with LED display, by connecting the timer of single-chip microcomputer, the display alarm time, is convenient to check that nurse replaces the interval time of infusion bottle, promotes to improve medical work efficiency.

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, this utility model is described in detail.The present embodiment is implemented premised on technical solutions of the utility model, give detailed embodiment and concrete operating process, but protection domain of the present utility model is not limited to following embodiment.
As Fig. 1, shown in Fig. 2, a kind of infrared-sensing type infusion alarm comprises infrared sensor 1, alarm 7, signal processing circuit 2, a/d converter 3, single-chip microcomputer 4, timer 5, wireless transmitter 6, reset circuit 10 and SR 11, infrared sensor 1 comprises infrared transmitting tube 12 and the infrared receiving tube 13 that inclined type is arranged in Mo Feisi dropper 17 both sides of infusion bottle, corresponding tilt angle is in 30 ° ~ 45 °, such as: 30 °, 40 ° or 45 °, as shown in Figure 5, infrared receiving tube 13 connection signal treatment circuit 2, signal processing circuit 2 connects a/d converter 3, a/d converter 3 connects single-chip microcomputer 4, single-chip microcomputer 4 is connection timer 5 respectively, alarm 7 and wireless transmitter 6, the supervisory computer 8 of wireless transmitter 6 wireless connections nurse job platform, SR 11 connects reset circuit 10, reset circuit 10 connects single-chip microcomputer 4.
Wherein, timer 5 is connected with LED display 9, can be used for showing the interval time of replacing infusion bottle, starts timing when starting to report to the police, and stops timing when nurse presses SR 11.
Infrared sensor 1 adopts E3F-5DN1E3F-5L correlation type infrared sensor, and its operation principle as shown in Figure 4.
As shown in Figure 2, single-chip microcomputer 4 is 51 single-chip microcomputers, provides 5V power supply by voltage stabilizing chip LM7805, low in energy consumption.Alarm 7 comprises bi-colour LED and buzzer 16, and bi-colour LED is connected single-chip microcomputer 4 respectively with buzzer 16, and wherein bi-colour LED comprises the normal green indicating lamp 15 of work of display and the red led 14 of display alarm.
As shown in Figure 3, this utility model device operation principle is as follows:
