Embodiment Construction

[0011] Attached below figure 1 The specific implementation manners of the present invention will be further described.

[0012] Specific implementation steps: when using the alarm device of the present invention, the user snaps the infusion set dripping funnel 2 into the alarm device dripping funnel slot 1, turns on the alarm power switch 5, and adjusts the position so that the light receiver 7 can normally receive the signal emitted by the light. The light obtained by the device 10 after passing through the water drop 9 (while the liquid is dripping, the working status indicator light 11 flashes to indicate that the adjustment is in place), and then the user presses the drip speed setting button twice when 2 drops of water drop 9 drop in the adjacent time 8 (as the user does not press the drop speed setting button 8, then the single-chip microcomputer 6 automatically receives the electric pulse signal generated by the light receiver 7 when the water drop 9 drops twice, and at...

Abstract

The invention provides an infusion alarm with a drop monitoring function. The principle of the infusion alarm with the drop monitoring function includes that light transmitted from a light transmitter (10) is changed by drops (9) from a dropper of an infusion set and then is transmitted to a light receiver (7), the strength of light signals of the light receiver (7) is converted into electric pulse signals to be further transmitted to a signal input end of a single-chip microcomputer (6), the single-chip microcomputer (6) judges whether the infusion set works normally or abnormally according to the electric pulse signals generated along with dropping of the infusion drops (9), and controls actions of a status indicating lamp (11) and a buzzer (3), and accordingly work status of the infusion set can be monitored and alarmed in real time.

Description

technical field [0001] The invention relates to a medical device, in particular to an infusion alarm. Background technique [0002] The existing infusion alarm mainly uses the principle of analyzing and processing the stock of infusion liquid to realize the alarm, and is affected by various uncertain factors during infusion, and the alarm error is relatively large. Contents of the invention [0003] In order to improve the problem of large alarm errors, the present invention provides an infusion alarm, which is composed of a dripper slot, a power supply, a power switch, an optical transmitter, an optical receiver, a single-chip microcomputer, a working status indicator light, and a buzzer. . The installation method of the mechanical part is: the path of the light emitted by the light transmitter is aligned with the water drops dropped by the infusion set; . The connection mode of the electrical system is: the power supply is connected to each component through the power...
