Abstract
The utility model relates to an automatic alarm device for monitoring whether an infusion to a patient is finished, in particular to a luminous flux difference infusion alarm, which comprises an infusion tube (9). The infusion tube (9) is provided with a clamp body shell (7). The clamp body shell (7) comprises a cavity in which a circuit board (8) is arranged. The circuit board (8) of the cavity is equipped with a point light source luminous tube (1). The circuit board (8) is connected with a button cell (6). The right side of the cavity body is provided with an upper light receiving tube (2) and a lower light receiving tube (3). A buzzer (4) is arranged in the cavity and an alarm lamp (5) is also arranged in the cavity body. The infusion alarm is not affected by colors of a liquid and an infusion apparatus and different transmittances as well as external light rays by employing the structure. When the liquid level is between the two light receiving tubes, the strengths of photoelectric signals generated by the two light receiving tubes have obvious difference. The infusion alarm can monitor whether the infusion is finished by reflecting the difference between two photoelectric signal strengths.
Description
One, technical field: this utility model relates to a kind of the autoalarm whether a kind of patient's of monitoring infusion finishes.Especially a kind of luminous flux difference infusion alarm.
Two, background technology: the autoalarm of medical infusion has multiple principle, as weighing principle, electrode principle, float principle, capacitance principle, vibrations principle, photovoltaic principals etc.And measure accurately, do not contact medicinal liquid, the autoalarm that should belong to photovoltaic principals that cost is relatively cheap.The infusion alarm of photovoltaic principals all is the size by the photosignal of measuring light receiving tube at present, judges whether liquid levels drops to certain monitoring location.Be exactly to compare on measuring principle with the measured value of photosignal and the setting value of a photosignal.Because different liquid is all inequality with different its color of transfusion device and light transmittance, add the influence (as luminous tube brightness, cell voltage) that component parameters changes, this setting value is difficult to determine, therefore produces wrong report and fail to report phenomenon inevitable.In order to prevent the influence of extraneous light, photoelectric infusion alarm all uses lighttight shell to encase in addition, and it is very little that this makes that infusion alarm can not be done.Make infusion alarm work more stable, debug simplyr, make dexterouslyr, just need overcome photoelectricity and set value doubt problem from measuring principle.
Three, summary of the invention: the purpose of this utility model provides a kind of monitoring transfusion liquid in time simple in structure, easy to use and finishes, the color of liquid body and transfusion device and light transmittance do not influence, and do not allow to be subject to the infusion alarm of ambient light and component parameters variable effect.Its technical scheme is: luminous flux difference infusion alarm, comprise tube for transfusion, the tube for transfusion outer wall is provided with the clamp shell, the clamp shell comprises cavity, be provided with circuit board in the cavity, be provided with the point light source light-emitting pipe near tube for transfusion one side on the circuit board of cavity left side, circuit board is connected with button cell, right side at cavity is provided with and the corresponding light receiving tube of setting out on a journey of point light source light-emitting pipe, following road light receiving tube near tube for transfusion, and set out on a journey light receiving tube and following road light receiving tube lay respectively at the upper and lower of point light source light-emitting pipe offside.In cavity, be provided with buzzer.In cavity, be provided with alarm lamp.Alarm is made the folder type, be clipped in the top of tube for transfusion.Adorn a point source type light emitting diode in a side of clip, upper and lower two places adorn two light receiving tubes at the opposite side of clip, and the position of two light receiving tubes and light emitting diode is symmetry up and down, and the diameter of spacing and common transfusion pipe is suitable.Adopt after the said structure, because between luminous tube and the light receiving tube is tube for transfusion, light path characteristic during normal infusion between luminous tube to two photoelectric receiving tube is the same, the photosignal intensity that two photoelectric receiving tubes the produce difference of comparing is little, not the color of liquid body and transfusion device and light transmittance is different and the influence of extraneous light.When liquid level is low between two light receiving tubes the time, just lost concordance from two light paths of point source to two photoelectric receiving tube, one road light has the liquid level refraction, and another road light does not have the liquid level refraction, and one road light is through liquid, and another road light is through air.The photosignal intensity that two photoelectric receiving tubes produce has tangible difference, and whether the size of the difference by reflecting two photosignal intensity can monitor out transfusion and finish.Transfusion report to the police not liquid body and the color of transfusion device and the influence of light transmittance do not allow to be subject to the influence that ambient light and component parameters change yet, and it is simple to make debugging, installs dexterousr.
Four, description of drawings: accompanying drawing 1 is a structural representation of the present utility model;
Accompanying drawing 2 is vertical views of the present utility model;
Accompanying drawing 3 is Application Example circuit diagrams of the present utility model.
Five, the specific embodiment: luminous flux difference infusion alarm comprises tube for transfusion 9, tube for transfusion 9 outer walls are provided with clamp shell 7, clamp shell 7 comprises cavity, be provided with circuit board 8 in the cavity, be provided with point light source light-emitting pipe 1 near tube for transfusion 9 one sides on the circuit board 8 of cavity left side, circuit board 8 is connected with button cell 6, right side at cavity is provided with and the point light source light-emitting pipe 1 corresponding light receiving tube 2 of setting out on a journey, following road light receiving tube 3 near tube for transfusion 9, and set out on a journey light receiving tube 2 and following road light receiving tube 3 lay respectively at the upper and lower of point light source light-emitting pipe (1) offside.In cavity, be provided with buzzer 4.In cavity, be provided with alarm lamp 5.
Claims (3)
1. luminous flux difference infusion alarm, comprise tube for transfusion (9), tube for transfusion (9) outer wall is provided with clamp shell (7), clamp shell (7) comprises cavity, be provided with circuit board (8) in the cavity, it is characterized in that: cavity left side circuit board (8) is gone up near tube for transfusion (9) one sides and is provided with point light source light-emitting pipe (1), circuit board (8) is connected with button cell (6), right side at cavity is provided with and the corresponding light receiving tube of setting out on a journey of point light source light-emitting pipe (1) (2) near tube for transfusion (9), following road light receiving tube (3), light receiving tube of setting out on a journey (2) and following road light receiving tube (3) lay respectively at the upper and lower of point light source light-emitting pipe (1) offside.
