Abstract
The invention relates to an automatic infusion ending reminding device. The automatic infusion ending reminding device comprises an infrared laser transmitter, an infrared photosensitive sensor, a microcontroller, an execution mechanism, a metal hoop and an alarm device. When liquid medicine is to be completely infused, focused light beams which can be emitted by the infrared laser transmitter in the device are received by the infrared photosensitive sensor which is right opposite to the infrared laser transmitter, the infrared photosensitive sensor gives out an illumination signal, the illumination signal is converted into a digital signal through analog-to-digital conversion conducted by the microcontroller and used for logic judgment, the microcontroller controls the alarm device to give out an acoustic-optical signal alarm and controls the execution mechanism to make the metal loop clamp an infusion pipe so as to slow down the flow speed of liquid medicine at the same time, and therefore time can be bought for medical staff to come to pull needles or change medicine. By means of the automatic infusion ending reminding device, patients can be relieved and have a rest before the infusion reminding device conducts reminding, or the medical staff can do other work before the infusion reminding device conducts reminding, and when liquid medicine infusion is to be completed, the phenomenon that when infusion is completed, blood of patients flows backwards and certain harmful effects are brought to the bodies of patients can be prevented through the infusion reminding device.
Description
Technical field
The present invention relates to the technical field of analysis and Survey control alarm device, make when transfusion closes to an end medicinal liquid flow velocity slow down in particular to one and then stop flowing, and timely acoustic luminous prompting patient or the low cost of medical personnel, light, reusable transfusion auxiliary device.
Background technology
In hospital, during patient fluid infusion, patient or medical personnel check whether medicinal liquid will be totally lost always every now and then, if the same time, transfusion outpatient quantity is more, and medical personnel are less again, then carelessness probably appears in medical personnel when looking after patient fluid infusion; And if patient health itself is more weak, needs to have a rest, do not have enough energy to check residual drug constantly; So all, at the end of easily causing transfusion, sufferers themselves and medical personnel do not know that transfusion terminates, and cause blood samples of patients to reflux, bring harmful effect to patient body.
Compared with current transfusion device, this transfusion terminates automatic alarm set and adopts infrared electro detection, high integrated microcontroller and steering wheel-metal ferrule combinations, can when transfusion closes to an end, slow down flow velocity and then stop liquid medicine flow, give the alarm, remind medical personnel to change transfusion bottle in time or take transfusion bottle away and terminate transfusion.
Summary of the invention
The object of the invention is to the problem needing people to nurse in real time when solving patient fluid infusion, a kind of compact structure is provided, transfusion with low cost, easy to use terminates alarm set.And this transfusion terminates the not direct contact liq of alarm set, safe and sanitary is reliable.Start to remind patient or medical personnel at the end of transfusion closes on, patient then can have a rest before alarm set sends prompting, and medical personnel also can do other work before alarm set sends prompting, greatly alleviate the labor intensity of medical personnel.
For solving the problem, the present invention is achieved by the following technical solutions: this transfusion terminates alarm set, comprises two cover photoelectric subassemblys (Infrared laser emission device-infrared light dependent sensor), is responsible for detection medicinal liquid level change; A microcontroller (Micro Control Unit, MCU), is responsible for signal detection, conversion, software system logic and actuator instruction and controls; An actuator (steering wheel); A metal cuff.Infrared laser emission device of the present invention-infrared light dependent sensor assembly is positioned at the both sides of tube for transfusion, and the radial arrangement of sensor cluster as shown in Figure 3.Infrared laser emission device and infrared light dependent sensor are just to configuration.
During no liquid, the focused beam that Infrared laser emission device sends, received by infrared light dependent sensor just right with it, infrared sensor has provided luminance signal, is digital signal, for logical judgment through microcontroller analog digital conversion; When having liquid, if liquid is opaque, then light cannot pass through, if liquid-transparent, but the refraction action of liquid makes optical path-deflecting, and the result of two kinds of situations is all that infrared light dependent sensor cannot receive illumination, export without luminance signal, be used for logical judgment through microcontroller analog digital conversion equally.
The photoelectric subassembly (Infrared laser emission device-infrared light dependent sensor) above of being positioned at of the present invention is when medicinal liquid flow to below this position, provide signal intensity, and then microprocessor controls alarm device sends sound and light signal warning, controls actuator (steering wheel) and makes the tight tube for transfusion of metallic sheath hoop clip to slow down medicinal liquid flow velocity simultaneously; Be positioned at photoelectric subassembly (Infrared laser emission device-infrared light dependent sensor) below when medicinal liquid flow to below its position, provide signal intensity, microprocessor controls alarm device continues to report to the police, and control actuator (steering wheel) and make metal cuff clamp tube for transfusion further, block liquid flow in tube for transfusion.
Accompanying drawing explanation
A kind of transfusion of Fig. 1 the present invention terminates the structural representation of alarm set.
Fig. 2 software logic flow chart of the present invention.
The radial arrangement figure of Fig. 3 photoelectric subassembly of the present invention.
In figure, 1-dropper 2-Infrared laser emission device 3-Infrared laser emission device 4-metal cuff 5-light sensor 6-light sensor 7-microcontroller 8-alarm device (buzzer and LED) 9-actuator (steering wheel).
detailed description of the invention:
When under the warning line at Infrared laser emission device 2 place that medicinal liquid flow in dropper 1 is sentenced, when being also 2 place's no liquid, the focused beam that Infrared laser emission device 2 sends, received by infrared light dependent sensor 5 just right with it, infrared light dependent sensor 5 has provided luminance signal, be digital signal through microcontroller 7 analog digital conversion, for logical judgment, and then microprocessor controls alarm device 8 sends sound and light signal warning, and control actuator 9(steering wheel simultaneously) make metal cuff 4 clamp tube for transfusion to slow down medicinal liquid flow velocity.
If microcontroller 7 job control actuator 9(steering wheel) make metal cuff 4 clamp tube for transfusion after, medical personnel are not had to come stopping infusion or change dressings, then when medicinal liquid continues below the warning line downstream to Infrared laser emission device 3 place, the focused beam that Infrared laser emission device 3 sends, received by infrared light dependent sensor 6 just right with it, infrared light dependent sensor 6 has provided luminance signal, and then microprocessor controls alarm device 8 continues to report to the police, and control actuator 9(steering wheel) make metal cuff 4 clamp tube for transfusion further, to block liquid medicine flow.
