Abstract
The utility model relates to a safe infusion apparatus which comprises a liquid dropping pipe, a floater in the liquid dropping pipe, a magnet in the floater and a magnetic reed switch. The magnetic reed switch is fixed at bottom end of the outer side of the liquid dropping pipe through a binding belt, the magnetic reed switch is in series connection with a buzzing circuit, and the buzzing circuit is formed by the a power source, the magnetic reed switch and a buzzer. When more liquid medicine exists in the liquid dropping pipe, the floater floats above the liquid surface, the liquid surface lowers, and the floater lowers along with the liquid medicine; when the liquid medicine flows out completely, the floater blocks the outlet of the liquid dropping pipe to prevent the liquid medicine from lowering continuously, at the same time the magnet in the floater triggers the magnetic reed switch to be closed, the buzzing circuit is switched on, and the buzzer sends out an alarm sound.
Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, is specifically related to a kind of transfusion device.
Background technology
Disposable transfusion device is a kind of common medical apparatus and instruments, and is easy to use, but also have weak point, needs patient or household or medical personnel nurse during transfusion, is in fear of the medicinal liquid back gas of being totally lost and enters the human vein blood vessel, causes reaction even death that some are bad.
Summary of the invention
The purpose of this utility model is the deficiency that exists at existing transfusion device, and a kind of safe transfusion system is provided, and can realize closing automatically and sending when medicinal liquid is lower than minim pipette chimes of doom.
The objective of the invention is to realize by following technological means: comprise the float in minim pipette, the minim pipette, also comprise magnet, magnetic reed switch in the float, magnetic reed switch is fixed on the minim pipette outer lower end by band, and magnetic reed switch is connected in the buzz circuit.
Compared with prior art the present invention has following tangible advantage: when the minim pipette inner liquid medicine more for a long time float float over more than the liquid level, float descends with medicinal liquid when liquid level descends, after medicinal liquid all flows out, float is blocked the outlet of minim pipette, prevent that medicinal liquid from continuing to descend, magnet in the float triggers the magnetic reed switch closure simultaneously, connects buzz circuit, and buzzer sends chimes of doom.
Description of drawings
Fig. 1 is structural representation of the present invention;
Among the figure, 1-minim pipette, 2-float, 3-magnet, 4-magnetic reed switch, 5-band, 6-buzzer.
The specific embodiment
The present invention is described in further detail below in conjunction with description of drawings and the specific embodiment:
Safe transfusion system as shown in Figure 1, comprise the float 2 in minim pipette 1, the minim pipette 1, magnet 3, the magnetic reed switch 4 in the float 2, magnetic reed switch 4 is fixed on minim pipette 1 outer lower end by band 5, magnetic reed switch 4 is connected in the buzz circuit, and buzz circuit is made of power supply, magnetic reed switch 4, buzzer 6 series connection.
The above; it only is a part of specific embodiment of the present utility model; protection domain of the present utility model is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that this utility model discloses; the variation that can expect easily or replacement all should be encompassed within the protection domain of the present utility model.
