Abstract
The utility model relates to a photoelectric infusion termination alarm apparatus, including an infrared generating circuit and an infrared receiving circuit, the both circuits are assembled on an infusion bottle hanger, an infrared light emitting tube of the infrared generating circuit and an infrared photoelectric tube of the infrared receiving circuit are arranged at the both sides of the corresponding positions of the bottle neck of an infusion bottle on the hanger oppositely. As the infrared light emitting tube of the infrared generating circuit and the infrared photoelectric tube of the infrared receiving circuit are arranged at the both sides of the bottle neck oppositely, when the infusion liquid level is lower than the preset liquid height of the photoelectric tube, the alarm apparatus can alarm automatically, so as to remind the nursing staff or the patients to take timely measures, the usage is convenient, practical and has certain popularization value.
Description
Technical field
This utility model relates to a kind of infrared ray electric alarms based on pattern recognition, belongs to electronic technology field.
Background technology
Realize control or warning by opto-electronic conversion, in each field extensive use of society.Infrared photo alarm system generally produces circuit by power circuit, infrared ray generation circuit, infrared radiation receiving circuit, warning message and speaker or siren etc. are formed by connecting in turn, the photocell of infrared radiation receiving circuit produces the signal of telecommunication after receiving optical signal, control warning message produces circuit and produces the setting sound equipment, sends chimes of doom by speaker or siren.This mode has obtained promotion and application at burglar alarm, Industry Control and field of traffic.
The utility model content
The purpose of this utility model is to provide a kind of infrared ray photoelectricity transfusion to stop alarm, in time reports to the police when transfusion is about to fail to the greatest extent in the infusion bottle to be implemented in, and avoids jeopardizing patient's life security because of in time not pulling out syringe needle.
For achieving the above object, the technical solution of the utility model is to have adopted a kind of photoelectric infusion to stop alarm, comprise infrared ray generation circuit and infrared radiation receiving circuit, each circuit is assemblied on the infusion bottle suspension bracket, the relative both sides that are installed on infusion bottle bottleneck correspondence position on the suspension bracket with the infrared photocell of infrared radiation receiving circuit of the infrared light emission pipe of above-mentioned infrared ray generation circuit.
Described infrared ray generation circuit is made of described infrared light emission pipe and adjustable resistance potentiometer series connection.
Described infrared radiation receiving circuit is in series by a described infrared photocell and an adjustable resistance potentiometer.
Because the infrared light emission pipe of infrared light emission circuit and the relative both sides that are installed on bottleneck of infrared photocell of infrared radiation receiving circuit, when the transfusion liquid level is lower than the residing liquid level of predefined photocell, this alarm is capable of automatic alarm, remind nursing staff or patient in time to take measures, the practicality that is easy to use has certain popularization value.
