Description
Technical field
The invention belongs to technical field of medical instruments, relate to a kind of infusion alarm, be specifically related to a kind of infusion alarm based on absorbance change.
Background technology
At present, in the clinical practice of global various big hospital and treatment and nursing mode, venous transfusion is a kind of conventional and effective mode, and in China, most of hospital transfusion amount reaches more than 93%.And present stage hospital conventional infusion there is many defects, as can not very well control transfusion precise time, add burden to entourage and doctors and nurses, patient is also difficult to safe recuperation when accepting infusion.If owing to manually neglecting process not in time during infusion-completed, blood backflow and the acupuncture treatment place serious swelling of patient will be caused, be unfavorable for patient treatment.And if process too early, bottle pipe removed by medicinal liquid when not being totally lost completely, cause unnecessary waste.In addition, if patient's trouble is infectious disease, the prevalence of medical personnel will be increased.
For this situation, designing one can the infusion alarm of automatic alarm be very important.
Summary of the invention
In order to solve above-mentioned technical problem, the invention provides a kind of can automatic alarm based on absorbance change infusion alarm.
The technical solution adopted in the present invention is: a kind of infusion alarm based on absorbance change, is characterized in that, comprising: power supply, optical generator, photoelectric sensor, master control borad, signal projector and alarm; Be connected in parallel with described optical generator after the series connection of described photoelectric sensor, master control borad, signal projector, composition parallel circuit, described power supply is connected with described parallel circuit in series, and described signal projector is connected with described alarm by wireless network.
As preferably, described infusion alarm also comprises switch, and described switch and described optical generator are connected in series; Can open when needs, can close under natural light or daylight lamp.
As preferably, described infusion alarm also comprises medical care main frame and medical care extension set, and described medical care main frame is connected with described signal projector by wireless network with medical care extension set.
As preferably, described optical generator is infraluminescence pipe.
As preferably, described power supply is lightweight button cell.
As preferably, the photodetector head that described photoelectric sensor inside is arranged is silicon phototriode, when liquid level of infusing is lowered through detecting head gradually, the change of this absorbance of window meeting perception of silicon phototriode, make silicon phototriode turning circuit, thus change optical signal into the signal of telecommunication, and be sent to signal projector by master control borad.
As preferably, the signal that described signal projector is launched comprises the bed label of this patient and medicinal liquid by most information.
As preferably, described alarm is buzzer siren, is provided with signal receiver and buzzing switch in it, and signal receiver receives the signal that signal projector is launched, and produces buzzing effect by internal drive circuits, reminds medical personnel to operate.
As preferably, above the Murphy's burette that the photodetector head of described optical generator and photoelectric sensor is installed on transfusion bag or infusion bottle on the leather strap of bottle mouth position.
Relative to prior art, advantage of the present invention and good effect are:
(1) infusion alarm of the present invention designs based on light transmission liquid with through the principle that absorbance during air can change, and light source obtains simple possible.Optical generator can be opened and replace natural light and daylight lamp under dark surrounds, all can use in any environment;
(2) when medicinal liquid by defeated to the greatest extent and occur to report to the police time, medicinal liquid liquid level is in is it possible that formula dropper upper end, and medical personnel are after receiving the infusion alarming signal of specifying bed label, and the time can had an appointment 1 minute arrives specifies bed label to carry out changing dressings liquid operation;
(3) infusion alarm of the present invention's design, can effectively alleviate medical personnel's work load, and avoid malpractice.

Fig. 2: the section components installation site figure of the specific embodiment of the invention.
Detailed description of the invention
Below with reference to the drawings and specific embodiments, the present invention is further elaborated.
Ask for an interview Fig. 1, Fig. 2, the technical solution adopted in the present invention is: a kind of infusion alarm based on absorbance change, comprising: lightweight button cell 1, infraluminescence pipe 2, switch 3, photoelectric sensor 4, master control borad 5, signal projector 6, buzzer siren 7, medical care main frame 8 and medical care extension set 9; The photodetector head that photoelectric sensor 4 inside is arranged is silicon phototriode, is provided with signal receiver and buzzing switch in buzzer siren 7; Infraluminescence pipe 2, switch 3 are connected in series, photoelectric sensor 4, master control borad 5, signal projector 6 are connected in parallel with infraluminescence pipe 2, switch 3 after connecting, composition parallel circuit, lightweight button cell 1 is connected with parallel circuit in series, and signal projector 6 is connected with buzzer siren 7, medical care main frame 8, medical care extension set 9 by wireless network.The signal that signal projector 6 is launched comprises the bed label of this patient and medicinal liquid by most information.Above the Murphy's burette that the photodetector head of optical generator 2 and photoelectric sensor 4 is installed on transfusion bag or infusion bottle on the leather strap of bottle mouth position.
When the present invention works, photoelectric sensor 4 perception transfusion liquid level is lower than the change of absorbance during assigned address, and then the signal to be changed by light transmission is converted into the signal of telecommunication, send this change to signal projector 6 by master control borad 6, this signal of telecommunication is emitted in buzzer siren 7 by wireless network and reports to the police by signal projector 6; Meanwhile, this signal of telecommunication is emitted to by wireless network on the display screen of medical care main frame 8 and medical care extension set 9 by signal projector 6, for medical personnel provide the source-information of alarm signal.
The present invention, can closing switch 3 under the natural light or daylight lamp environment of abundance, thus closes infraluminescence pipe 2, can opening switch 3 as required in dark surrounds, thus opens infraluminescence pipe 2.Light beam is injected to another side through dropper by this infraluminescence pipe 2, by the silicon phototriode window reception of photoelectric sensor 4.The silicon phototriode of photoelectric sensor 4 why can defeated this change to the greatest extent of perception medicinal liquid, principle be when the liquid in infusion bottle also not defeated to the greatest extent time, inner transparent medicinal liquid has transmission optically focused effect, light-sensitive element transmits a transmissivityτ 1, when medicinal liquid defeated to the greatest extent after, inner air instead of medicinal liquid, and light-sensitive element transmits a transmissivityτ 2, and τ 1 ≠ τ 2, silicon phototriode perceives the radiative absorbance change of optical generator.Photoelectric sensor 4 can receive absorbance and change this optical signalling, thus detects the change of liquid level water level contactlessly, and medicinal liquid is become the signal of telecommunication from the change transitions had to nothing, sends signal projector 6 to by master control borad 5.Thus realize warning function of the present invention.
These are only preferred embodiment of the present invention, be not intended to limit protection scope of the present invention, therefore, all any amendments done within the spirit and principles in the present invention, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
