Abstract

The utility model discloses an electronic transfusion alarm, wherein, three sides of a square shell are respectively provided with a power socket, a power switch, a loudspeaker, a conversion socket and a conversion switch; the shape of a liner matches with that of the head part of an infusion bottle; the position of the liner relative to the bottleneck of the infusion bottle is provided with two groups of beam emitting sources and beam receiving sources; a circuit board is fixed on an outer wall of the liner; the lower end of the liner and the shell are connected into a whole through an end cover; a hanger is connected with the shell. As the utility model adopts the principle of photoelectricity induction and liquid refraction, when the liquid level is lower than the positions of the beam emitting sources and the beam receiving sources, an alarming sound is sent out, otherwise the alarm does not work.

Description

The Electric Infusion Alarm Device

The utility model relates to a kind of The Electric Infusion Alarm Device, belongs to medical special-purpose field.

Hospital adopts traditional manually finishing to patient's infusion monitoring always, and the paramedic will ceaselessly watch each patient's of each ward transfusion situation, has not only increased paramedic's working strength, also influences the patient and has a rest.

The utility model provides a kind of The Electric Infusion Alarm Device at the problems referred to above, and when using its transfusion, the personnel of need not look after, and transfusion finishes and reports to the police automatically.

Task of the present utility model is finished as follows: on three sides of positive square shell, supply socket and power switch, loudspeaker, conversion socket and switch have been installed respectively, inner bag shape and infusion bottle nose shape match, two groups of radiation beam sources and light beam reception sources are installed at inner bag on corresponding to infusion bottle bottleneck position, circuit board is fixed on the inner bladder outer wall, the inner bag lower end is fixedly connected by end cap and shell and is integral, and suspension bracket is connected with shell.

The utility model adopts optoelectronic induction and liquid refracting principle on principle of work, when liquid level in the infusion bottle is lower than radiation beam source and light beam reception sources position, sound the alarm, otherwise alarm is not worked.

Below in conjunction with accompanying drawing the utility model is done and to be described in further detail:

Fig. 1 is the utility model one-piece construction axial view

Fig. 2 is the utility model one-piece construction radial view

Fig. 3 is the utility model circuit diagram

With reference to accompanying drawing 1,2, on three sides of positive square shell [1], supply socket [2] and power switch [3], loudspeaker [4], conversion socket [5] and switch [6] have been installed respectively, inner bag [7] shape and infusion bottle nose shape match, two groups of radiation beam sources [8] and light beam reception sources [9] are installed at inner bag on corresponding to infusion bottle bottleneck position, circuit board [10] is fixed on the inner bladder outer wall, the inner bag lower end is fixedly connected by end cap [11] and shell and is integral, and suspension bracket [12] is connected with shell; With reference to accompanying drawing 3, earlier infusion bottle is put into inner bag, socket power CZ1, power supply adopts miniature transformer and the electric power system that standby rechargeable battery is formed that can export the 3V direct supply, can reach has electricity or the alarm for electricity failure itself can both operate as normal, turn on the power switch K1, this moment, radiation beam source was started working, launch a branch of visible light beam, when liquid in the bottle is lower than radiation beam source and light beam reception sources position, D1 makes it to produce potential difference (PD) at the H point after receiving external infrared light supply, at this moment BG1 conducting, through BG2, after BG3 amplifies, convert two-way output to by K2, as K2 during in the A position, external alarm is started working and is sent chimes of doom, demonstrating which sick bed patient of which ward on the terminal display screen of nursing station has infused and has finished, in time remind medical personnel to handle, when K2 during in the B position YS start working, chimes of doom is received at the scene, and when liquid was higher than radiation beam source and light beam reception sources position in the bottle, radiation beam source visible light emitted bundle can not be dropped on the light beam reception sources D1 by liquid refracting, in circuit, there is not light signal, just can not produce potential difference (PD) at the H point, at this moment BG1 then is in closed condition, and alarm is not worked, be that alarm free produces, if make the liquid that is packed in bag, can in use install packed infusion bottle additional, equally can realize warning function.

Claims

1, a kind of The Electric Infusion Alarm Device, it is by supply socket [2] and power switch [3], loudspeaker [4], conversion socket [5] and switch [6], radiation beam source [8] and light beam reception sources [9] constitute, it is characterized in that: on three sides of positive square shell [1], supply socket [2] and power switch [3] have been installed respectively, loudspeaker [4], conversion socket [5] and switch [6], inner bag [7] shape and infusion bottle nose shape match, two groups of radiation beam sources [8] and light beam reception sources [9] are installed at inner bag on corresponding to infusion bottle bottleneck position, circuit board [10] is fixed on the inner bladder outer wall, the inner bag lower end is fixedly connected by end cap [11] and shell and is integral, and suspension bracket [12] is connected with shell.
