Abstract
An automatic infusion alarm device comprises a fixed device, a photosensitive coupled apparatus, a battery compartment, a light-emitting diode and a single-chip microcomputer. The automatic infusion alarm device is characterized in that the photosensitive coupled apparatus is a light-emitting diode and a photosensitive resistor, the fixed device is of a contact type, and a small hole only allowing an infusion tube to pass through is arranged at the upper end of the fixed device. The automatic infusion alarm device has the advantage that during infusion, under the condition that liquid medicine is exhausted in drop mode or a needle is departed from the blood vessel, the automatic infusion alarm device can give an alarm, liberates manpower, achieves safe infusion, is low in cost, simple and easy to use and suitable for users at any age and with any cultural background, guarantees hygiene, cannot be influenced by germs in the air in the hospital in a recycling process, and cannot infect medicine used by the infusion.
Description
Technical field
This utility model relates to a kind of medical transfusion alarm device, relates in particular to a kind of automatic alarm for infusion.
Background technology
Having an intravenous drip is the thing that everyone can experience, and has an intravenous drip for long-term ill patient, is main therapeutic modality.If do not drip to the greatest extent and not in time discovery but meet liquid medicine when having an intravenous drip, it then is the thing of a quite dangerous.In existing design, mainly be infra-red method, weight method etc., and the kind of medicine, density etc. all can produce certain influence to it, thus reduced the accuracy of automatic alarm.Therefore, be necessary to provide a kind of automatic alarm for transfusion, the design sends sound and light alarm by detecting drop drippage situation, drip to the greatest extent so be not only liquid medicine, in the situation of drum pin, drop also can stop drippage in the dropper, this device can be reported to the police equally, kill two birds with one stone, possess simultaneously two kinds of warning functions in the situation, have suitable Practical significance.
Summary of the invention
This utility model provides a kind of automatic alarm for infusion, drips at infusion medicine in the situation of most or drum pin, can carry out alarm, to reach the liberation human resources, to make the safer purpose of transfusion.
For reaching above purpose, this utility model adopts following technical scheme: comprise shell, photosensitive coupled apparatus, battery compartment and control unit, it is characterized in that described photosensitive coupled apparatus is that optical transmitting set is relative with optical receiver and settles, described shell is provided with by its upper end and only holds aperture that tube for transfusion passes through and be articulated in and drip on the fast pipe.
Preferably, described shell covers drip fast indicator tube fully.
Preferably, the light of described light emitters emission is visible light, ultraviolet light or infrared light, visible light and ultraviolet light adopt be drop to the refraction of light, what infrared light adopted is that drop is to Optical Absorption.
Preferably, be provided with on and off switch and reset switch on the described automatic alarm for infusion.
Preferably, the core component of described control unit is single-chip microcomputer.
When the beneficial effects of the utility model are transfusion, liquid medicine drips to the greatest extent or rouses in the situation of pin, this device can be reported to the police, and not only liberate manpower, but also reached the effect of safe infusion, and with low cost, be simple and easy to use, be applicable to the user of any age bracket, any culture background, and guarantee health, in the recycling process, be not subjected to the impact of pathogenic bacteria in the air in the hospital, can be infected with the used medicine of transfusion.
Description of drawings
In order to be illustrated more clearly in the technical solution of the utility model, the accompanying drawing of required use was done to introduce simply during the below will describe embodiment, apparently, accompanying drawing in the following describes only is embodiment more of the present utility model, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is this utility model front view;
Fig. 2 is this utility model top view;
Fig. 3 is this utility model program flow diagram;
Among the figure: 1. battery compartment, 2. on and off switch, 3. reset switch, 4. single-chip microcomputer, 5. buzzer, 6. shell (clip shape), 7. optical transmitting set, 8. optical receiver.
The specific embodiment
The below is explained in detail the technical solution of the utility model, automatic alarm for infusion, comprise shell 6, optical transmitting set 7, optical receiver 8, battery compartment 1, light emitting diode (is arranged at the inside of optical transmitting set 7, photoconductive resistance (being arranged at the inside of optical receiver 8) and single-chip microcomputer 4, described photosensitive coupled apparatus comprises light emitters and light receiver, described optical transmitting set utilizing emitted light is visible light, is provided with on and off switch 2 and reset switch 3 on the described automatic alarm for infusion, and used cell voltage is greater than 2.5V.Shell can hang on the fast indicator tube equipment, then equipment can be opened in the position that on and off switch (toggle switch) is pushed " opening ", every LED lamp flicker once, flicker frequency judges that dripping speed drips speed with regulating whereby, need to prove, during the drop drippage, can produce refraction to the light of light emitting diode emission, voltage in the photoconductive resistance can produce respective change, because different medicines are different to the refractive index of light, so the waveform wavelength-division that different medicines produce and the height of trough are not quite similar, so can not judge drop drippage situation with a fixing value.The method that the design adopts be detection waveform rising edge or the mode of trailing edge.Namely judge the poor of magnitude of voltage, when this difference surpasses certain limit, then be judged as the liquid drippage.When voltage difference is no more than this scope, then think electromagnetic interference, can ignore the interference of this moment.When system detects the time when surpassing 10 times of drop Drain time last time and still not having the drop drippage, buzzer warning (very brief warning is that dropping liquid flows to end or the drum pin, and long acoustic alarm is undertension).If the transfusion place from the nurse room away from, can slow down liquid droping speed, or stop dropping liquid, prevent from dripping that drop flows to end cause danger in the fast indicator tube.If the transfusion place from the nurse room close to, can directly notify the nurse to change dressings.Behind the system alarm, can with stop alarm, and again enter alarm condition by reset key direct reduction system, perhaps directly close power source of alarm.
The above person, being preferred embodiment of the present utility model only, is not to limit practical range of the present utility model, and namely all equalizations of doing according to this utility model change and modify, be all this utility model claim scope and contain, give an example no longer one by one here.
