Abstract
A liquid level reminding device can prompt when nearly no liquid exists in an infusion bottle during infusion, so patients or family members of the patients do not have the trouble on paying attention on whether the liquid in the infusion bottle is almost infused completely or not during the infusion, are relieved under the condition that the patients are weak and the family members are tired, and can obtain more time for rest. Positioning covers, a shell, a phototriode, a light-emitting diode, a current-limiting resistor, a composite triode, a buzzer and a button cell are sequentially connected with one another. The light-emitting diode and the phototriode are respectively fixed in round holes which are drilled on the left and the right positioning covers, and the axes of the light-emitting diode and the phototriode are intersected with each other for a certain angle. The positioning covers are used for tightly attaching to and clamping the conical surface of the bottleneck of the infusion bottle. When the infusion is carried out, because the light-emitting diode obliquely illuminates, under the condition of full liquid, the phototriode is not illuminated by the light-emitting diode and is not switched on, so the buzzer does not sound; and when the liquid is nearly infused completely, because of the total reflection principle of the liquid level, the light of the light-emitting diode is reflected on the photoreception surface of the phototriode, so the triode is switched on, the buzzer sounds to prompt the patients or nurses to pull out a needle or change infusion solution.
Description
Affiliated technical field
This utility model relates to a kind of simple liquid level alarm set, the alarm set when infusion bottle is near aneroid when especially being useful for transfusion.
Background technology
During transfusion, patient or families of patients all are being concerned about the position of liquid in the infusion bottle always, when especially the liquid in infusion bottle is left few situation, make the people more will concentrate one's energy to stare at the interior liquid of infusion bottle, prepare the calling nurse and pull out pin or change medicine.This situation is not only wasted the time of having a rest of patient or families of patients, has forgotten sometimes, also causes liquid to be totally lost easily, and backflow of blood returns the serious consequence of tube for transfusion.
Summary of the invention
In order to realize infusing, one bottle of liquid will be totally lost, and remind patient, families of patients or nurse.This utility model provides a kind of liquid level alarm set, and the liquid that this device can be in infusion bottle makes buzzer sounding reminding patient or nurse on the device when not having.
The technical scheme that its technical problem that solves this utility model adopts is: locating cover, shell, phototriode, light emitting diode, current-limiting resistance, compound transistor, buzzer, button cell are linked in sequence.Light emitting diode, phototriode are separately fixed in the circular hole that gets out on the left and right locating cover, the angle that the two elements axes intersect is certain.Locating cover is used for being adjacent to, blocking the bottleneck taper surface place of infusion bottle.During transfusion, because light emitting diode obliquely upward to irradiation, is expired under the liquid situation, phototriode is not shone by light emitting diode, not conducting, and buzzer does not pipe; When liquid when being totally lost because the total reflection principle of liquid level, the luminous reflectance that makes light emitting diode on the photosurface of phototriode, the audion conducting, buzzer call reminds patient or nurse to pull out pin or change liquid.
The beneficial effects of the utility model are, in the time of can allowing patient or families of patients need not take a lot of trouble to note transfusion, whether liquid soon is totally lost in the infusion bottle, and under the situation of the weak family members' fatigue of patient, the energy of freeing them makes them that the more time of having a rest can be arranged.
