Abstract
The utility model relates to a transfusion-indicating device comprising an air bag of which both ends are respectively and fixedly connected with an electromagnet and a magnetizer; a compression spring is arranged between the electromagnet and the magnetizer; one of the electromagnet and the magnetizer is fixed, and the other is movable; a movable contact is fixedly connected to a movable end; when a certain amount of air in the air bag is exhausted, a fixing contact is arranged at the corresponding position of the movable contact; an alarm circuit is arranged between the movable contact and the fixing contact. The utility model can indicate infusion completion as well as can control infusion speed by means of the electromagnet adjusting current.
Description
Affiliated technical field
This utility model relates to a kind of transfusion indicator.
Background technology
Need the patient of transfusion often relatively weaker, therefore need the people and accompany and constantly pay close attention to liquid level variation in the infusion bottle when transfusion, medical personnel also need frequent tour simultaneously.If people's inadvertent that nobody accompanies or accompanies, perhaps medical personnel are busy with one's work, and liquid has been beaten and not discovery in time, can cause certain danger.
Summary of the invention
The purpose of this utility model is to overcome the above-mentioned defective of prior art, and the transfusion indicator of the automatic alarm of a kind of energy is provided.
This utility model comprises air bag, fixedly connected with magnetic conductor with electric magnet respectively in the two ends of air bag, be provided with the compression spring between electric magnet and the magnetic conductor, one of them fixes electric magnet and magnetic conductor, another activity, be fixedly connected with moving contact at movable end, the air in air bag is discharged from a certain amount of the time and the corresponding position of moving contact is provided with static contact, is provided with warning circuit between moving contact and the static contact.
During use, air bag is connected with infusion bottle, and the conducting electric magnet, gravitation produced between electric magnet and the magnetic conductor, its movable end overcomes the pressure of spring slowly to be drawn close to fixing an end, air bag is compressed in this process, because air bag communicates with infusion bottle, the compressed speed of air bag is the speed of infusion bottle transfusion, moving contact moves with movable end simultaneously, moving contact also contacts with static contact after air bag is discharged air in certain amount, makes warning circuit work, and the prompting transfusion is near completion.
By operation principle of the present utility model as seen, this utility model can not only point out transfusion to finish, can also be by the adjusting control transfusion speed to electromagnet current.
Description of drawings
Further illustrate particular content of the present utility model below in conjunction with drawings and Examples.
Accompanying drawing is the configuration diagram of present embodiment.
The specific embodiment
As shown in the figure, present embodiment comprises air bag 1, fixedly connected with magnetic conductor 3 with electric magnet 2 respectively in the two ends of air bag 1, be provided with compression spring 4 between electric magnet 2 and the magnetic conductor 3, wherein electric magnet 2 ends are movable, magnetic conductor 3 one ends are fixed, be fixedly connected with moving contact 5 at electric magnet 2 ends, air in air bag 1 is discharged from 100cc respectively, 250cc, position corresponding with moving contact 5 during 500cc is provided with three static contacts 6 separately, be provided with warning circuit 7 between moving contact 5 and the static contact 6, between three static contacts 6 and moving contact 5, be provided with control device simultaneously 6 energy of each stationary contact are contacted with moving contact 5 separately.This control device is an insulation portable plate 8 that is provided with perforate in the present embodiment, and this insulation portable plate 8 can be moved on the direction that moving contact 5 moves, and this perforate can be held moving contact 5 and pass.
