Abstract
The utility model relates to an automatic infusion alarm device, which belongs to a medical device. The utility model is provided with an infrared luminous tube A1, an infrared receiving tube A2 which is connected with an integrated block IC, a transistor V which is connected with the integrated block, and a buzzer B which is connected with the transistor V. The alarm device can be installed on the uppermost end of a transfusion tube. When medicine liquid in a medicine bottle drops up and liquid level in the transfusion tube is lower than the position of the infrared luminous tube, the buzzer can send out sound to remind the replacement of bottles or the withdrawal of needles. Consequently, serving personnel's or nursing personnel's labor and burden are relieved, and unnecessary trouble is avoided.
Description
This utility model provides a kind of medical appliance, especially a kind of transfusion automatic warning device.
When being patient infusion, when families of patients of staying in the ward to look after the patient night and day and nursing staff for changing bottle or pulling out pin and expend many energy and times.At present, owing to exist nursing staff's problem on the low side in the hospital, can't accomplish all patients are carried out monitoring constantly, therefore when transfusion person need change bottle or pull out pin, the personnel that need stay in the ward to look after the patient night and day usually notified the nursing staff to realize to nurse station.Therefore families of patients is just observed the residue situation of the medicinal liquid in the transfusion bottle every now and then often from hanging up transfusion bottle, worries because of fearing to have dripped.This brings very big inconvenience to stay in the ward to look after the patient night and day personnel and nursing staff.
The purpose of this utility model provides the automatic attention device of a kind of transfusion, and it can make things convenient for, inform in time to infuse finishes, to alleviate stay in the ward to look after the patient night and day personnel and nursing staff's burden.
This utility model is to realize like this, the automatic attention device of infusing, it has the infraluminescence pipe to be connected between a certain foot and adjustable resistance of integrated package, there is infrared receiving tube to be connected between another foot and resistance of integrated package, adjustable resistance and resistance eutral grounding, integrated package is connected to the base stage of audion again on the foot, is connected to buzzer on the colelctor electrode of audion, and buzzer connects positive source.
Medicinal liquid in transfusion bottle drips off, and when the liquid level in the tube for transfusion was lower than infraluminescence pipe position, buzzer sent alarm sound, and stay in the ward to look after the patient night and day personnel or nursing staff just are apprised of, and the transfusion bottle inner liquid medicine drips off, should change bottle or pull out pin.Thereby alleviated stay in the ward to look after the patient night and day personnel and nursing staff's burden, avoided many unnecessary troubles.
Below in conjunction with description of drawings concrete structure of the present utility model and operation principle.
Accompanying drawing is a circuit diagram of the present utility model.
As shown in drawings, the automatic attention device of the transfusion of this utility model, there is infraluminescence pipe A1 to be connected between 14 feet and adjustable resistance Rp of 74LS04 type ic chip, infrared receiving tube A2 is connected between 13 feet and resistance R of 74LS04 type ic chip, Rp, another termination power cathode of R, 14 feet of 74LS04 type integrated package connect positive source, be connected to capacitor C on 13 feet, the other end ground connection of capacitor C, 11,12 feet are connected on 1 foot, 9, the 1O foot connects together, the base stage of 8 feet and audion V connects together, the grounded emitter of V, be connected to buzzer B on the colelctor electrode, another termination positive source of B.
This attention device utilizes infrared light to be absorbed the different principle of degree in air and liquid, adjusts adjustable resistance Rp in advance, and to suitable electric current of infraluminescence pipe A1, the infrared light intensity that A1 is sent only can see through tube for transfusion dead circuit when aneroid (promptly in the pipe).When in the tube for transfusion between infrared luminous tube, the receiving tube medicinal liquid being arranged, the infrared light that the infraluminescence pipe sends is absorbed, and this moment, the resistance value ratio of receiving tube was less, and the electric current major part that is input on the ic chip is flowed away by the infrared receiving tube loop.When in the tube for transfusion during aneroid, the infrared light grow that infrared receiving tube receives, the resistance of itself also just increases, make transistor base current become big, form bigger electric current between audion V colelctor electrode and the emitter stage, buzzer sends the melodious sound of " ticking ", informs that transfusion finishes.
Can be connected to display lamp A between 2 feet of ic chip and the positive source.
Entire circuit can be installed in the shell.Be installed on the top of tube for transfusion during use and make infraluminescence pipe, receiving tube relative every tube for transfusion.
