Description
Technical field
This utility model relates to a kind of armarium, relates in particular to a kind of infusion alarm, in particular to a kind of contactless infusion alarm.
Background technology
At present, the alarm of medicinal liquid surplus during infusion monitoring, usually adopt the infusion monitor of contact, promptly flow through tube for transfusion to the patient in the intravital process at medicinal liquid, must the flow through monitor of a setting, the situation of this watch-dog infusion monitoring in infusion process is in case the discovery situation unusually then report to the police at once.
Above-mentioned transfusion device alarm though solved the more existing problems of no infusion monitoring, also exists following weak point: at first, the transfusion watch-dog of must flowing through, and watch-dog contacts with medicinal liquid, therefore exists expendable consumed product, and use cost is high; Secondly, the common volume of existing contact infusion monitor is bigger than normal, the mobile inconvenience of patient in infusion process; The 3rd, use comparatively complexity, user must be through normally use of training; The 4th, because the use traffic control technology, so must add flow pump and expensive pick off, and semi-conductive variations in temperature can produce great influence to detection accuracy, under high and cold in the open air, the hyperpyrexia state, especially in the field medicine, it is practical be worth little; The 5th, the equipment price costliness can't large-scale promotion be used; The 6th, power consumption is big, general infusion process about one hour or more than, with battery-operated micro pump and pick off, circuit such as amplifier, can not work for a long time, and external AC power supply makes transfusion person handicapped.
The utility model content
The technical problems to be solved in the utility model provides a kind of contactless infusion alarm, and this infusion alarm does not directly contact with medicinal liquid, uses and low cost of manufacture, job stability and adaptability height.
In order to solve the problems of the technologies described above, a kind of contactless infusion alarm of this utility model adopts following technical scheme: comprise the alarm receptor that is arranged near medical personnel, and the infusion test device that is connected with described alarm receptor wireless signal, described infusion test device comprises photodetector, the microcontroller that is electrically connected, signal projector, audible-visual annunciator, and tubing clamp system; Described photodetector comprises and is arranged at light launcher and the light sensor that the outer both sides of dropping funnel are located along the same line that described light launcher and light sensor and dropping funnel have certain included angle.
Preferably, the angle between described light launcher and light sensor and dropping funnel is between 0 ° to 90 °.Described photodetector and microcontroller are integrated in same circuit board.Described microcontroller is a Programmable Logic Controller.Described microcontroller has the external data interface.Described audible-visual annunciator comprises buzzer and light emitting diode.
Compared with prior art, the pick off that the contactless infusion alarm of this utility model need not be expensive, parts such as micro pump, cost is low, volume is little, power consumption is low, no matter all can use under the general hospital still is field condition; Non-contact measurement need not consumptive material, saving fund; The photodetection part is connected with dropping funnel by fast interface, accurate positioning, and it is convenient to load and unload, easy operating; Infusion test device fuselage number shows by display screen, and is simple and clear, be difficult for makeing mistakes, and can follow the trail of patient data fast.In addition, adopt sound and light alarm, can in time notify medical personnel also fast patient to be positioned, can not incur loss through delay.
Description of drawings
Fig. 1 is the structural representation of the contactless infusion alarm of this utility model;
Fig. 2 is the schematic diagram of transfusion control device shown in Figure 1;
The specific embodiment
Fig. 1 is the structural representation of the contactless infusion alarm of this utility model; As shown in the figure, the contactless infusion alarm of this utility model comprises the transfusion control device 2 that is arranged on the dropping funnel 1, and is arranged at the alarm receptor 3 near medical personnel, and described transfusion control device 2 and alarm receptor 3 are connected by wireless signal.Wherein, described transfusion control device 2 comprises photodetector 21, microcontroller 22, and tubing clamp system 23, audible-visual annunciator 25, and above-mentioned electronic device connects by electric wire, and described microcontroller 22 also is connected with signal projector 24.Described photodetector 21 comprises light launcher 211 and the light sensor 212 that is arranged at dropping funnel 1 both sides respectively.Described alarm receiver 3 comprises signal receiver 31, display screen 32, and audible-visual annunciator 33.
Schematic diagram in conjunction with the structural representation of contactless infusion alarm shown in Figure 1 and transfusion control device shown in Figure 2, be a straight line between light that the light launcher 211 of the photodetector 21 of the contactless infusion alarm of this utility model is launched and the light sensor 212, described light launcher 211 and light sensor 212 are certain angle with dropping funnel, are arranged at the both sides of dropping funnel respectively.Because, speed can change when light entered into another medium from a kind of medium, thereby produced the refraction angle, when light launcher 211 is injected dropping funnel at an angle with a linear light source, as there being liquid to exist in the dropping funnel, then thereby light can reflect and be offset certain angle, can't reach the light sensor in alignment with it 212; After transfusion finishes, because no liquid exists in the dropping funnel, thereby refraction effect does not take place, so the light of light launcher 211 emissions is injected light sensor 212 through straight line.After light sensor 212 receives optical signal, send instructions to microcontroller 22, send control command control piper clipping system 23 by microcontroller 22 and clamp pipeline, prevent patient blood refluence dropping funnel, simultaneously, microcontroller 22 is to signal projector 24, send instruction with audible-visual annunciator 25, send signal by this signal projector 24 to the alarm receptor 3 that is arranged near medical personnel, after alarm receptor 3 receives signal, by showing transfusion person's infusion test device fuselage number by display screen, and carry out sound and light alarm, the caution medical personnel in time handle.
Described microcontroller 22 is able to programme and is built-in with the microprocessor of input/output port, described microprocessor, and signal emission module all is ready-made integrated package or commercial modules; The concrete form of described tubing clamp has multiple, and main member is sophisticated commercial product; Described audible-visual annunciator is made of buzzer and light emitting diode; Described photodetector and microprocessor are integrated on the same circuit board, and the external data interface is the input/output interface of microprocessor; So the contactless infusion alarm of this utility model is the integrated of a kind of ripe hardware product and self-programmed software program.
The contactless infusion alarm of this utility model need not be expensive pick off, parts such as micro pump, cost is low, volume is little, power consumption is low, no matter all can use under the general hospital still is field condition; Non-contact measurement need not consumptive material, saving fund; The photodetection part is connected with dropping funnel by fast interface, accurate positioning, and it is convenient to load and unload, easy operating; Alarm fuselage number shows by display screen, and is simple and clear, be difficult for makeing mistakes, and can follow the trail of patient data fast.In addition, adopt flashing light to report to the police and sound and light alarm, can in time notify medical personnel also fast patient to be positioned, can not incur loss through delay.
Above disclosed only is preferred embodiment of the present utility model, can not limit the interest field of this utility model certainly with this, and therefore the equivalent variations of being done according to this utility model claim still belongs to the scope that this utility model is contained.
