Liquid-deficiency alarm of infusion apparatus

Abstract

A liquid-deficiency alarm of an infusion apparatus is characterized by comprising an infusion apparatus observing pipe 1, a floating ball 2, magnets 3, a reed pipe 4, a battery 5, a signal processor 6, a loudspeaker 7 and an indicator light 8, wherein the magnets 3 are mounted in the floating ball 2 and put in the infusion apparatus observing pipe 1, the reed pipe 4 is mounted at the outer lower part of the infusion apparatus observing pipe 1, two external connection wires of the reed pipe 4 are connected in series with the battery 5 and the signal processor 6, and an output end of the signal processor 6 is connected with the loudspeaker 7 and the indicator light 8. In the infusion process, a liquid is arranged in the infusion apparatus observing pipe, the floating ball is always located at the upper part of the infusion apparatus observing pipe under the buoyancy of the liquid, when the reed pipe of the alarm of the infusion apparatus doesn't detect a magnetic field emitted by the magnets, the reed pipe is in a normally open state, and the alarm doesn't work; when an infusion bottle contains no liquid, the floating ball moves downwards with reduction of the liquid in the observing pipe; when the floating ball moves to the bottom of the observing pipe, the reed pipe is in a closed state under the action of the magnetic field, at the moment, a circuit is formed in the alarm, the alarm gives an alarm, and the indicator light gives out light to remind a nurse or an accompanying person of replacing the infusion bottle for a patient.

Description

technical field [0001] The invention relates to an alarm, in particular to an alarm for lack of liquid in an infusion set. Background technique [0002] Treating patients in the hospital is inseparable from the infusion set. When infusing the patient, someone must accompany the patient to observe the situation of the infusion. Monitoring 5 or 6 patients, sometimes the infusion situation of the patients cannot be monitored in time, which will cause unnecessary trouble. Contents of the invention [0003] The purpose of the present invention is to overcome the disadvantages of the above-mentioned prior art, and to provide a liquid-short alarm for an infusion set. [0004] The present invention is achieved through the following technical solutions; [0005] The liquid shortage alarm of the infusion set is characterized in that it comprises an infusion set observation tube 1, a floating ball 2, a magnet 3, a reed switch 4, a battery 5, a signal processor 6, a loudspeaker 7 an...
