Description
Technical field
Portable infusion monitor of the present invention is specifically related to transfusion liquid detection, control and alarm device in a kind of hospital care.
Background technology
Transfusion device uses very extensive in medical institutions, tradition is whether artificial visually examine's method is discerned transfusion and finished, and fails in time to find if liquid finishes, and can cause blood to reflux, the harm patient.Use infusion alarm can reduce hand labor intensity, improve the nursing level of hospital.
Present some domestic infusion alarms, at the detection side liquid face, have weight method, laser optical method, electrode to insert multiple survey methods such as the direct method of measurement, photoelectric measurement method, capacitance measurement, there is the infusion bottle of measurement liquid level the measuring position, measures dropping liquid number of times in the kettle, measures liquid level or the like in the tube for transfusion.Each method all has its pluses and minuses, and the most practical method is the liquid level that photoelectric method is measured the transfusion liquid in pipe.But how using the liquid in the reliable and effective measurement tube for transfusion of photoelectric method energy, avoid extraneous light to disturb, is a technical barrier.
Some infusion alarm is closed liquid functional, and can arrive medical personnel after transfusion finishes stops before transfusion or the replacing liquid liquid being closed, to leave medical personnel's more time of just being busy with other affairs for.Moreover at suitable liquid level closing liquid, it is convenient that medical personnel change liquid, avoids carrying out work such as aerofluxus.The patent No. is 200420006730.4 to be exactly a kind of infusion alarm that can closing liquid described in the Chinese patent public technology.Its complex structure, volume is big, needs manually firmly to reset closing organ, has been difficult to practicality.
Some infusion alarm also has warning distant place output function except sound and light alarm.Can connect the hospital care calling system, alarm signal is directly passed to nurse room or night shift room.Ideal output signal can not be exported with lead.It is very inconvenient that transfusion device has lead to connect use, and patient is difficult to carry liquid and goes to the toilet, and another has reduced patient's comfort.The patent No. is 200420065194.5 to disclose the principle of using infrared emission realize the reporting to the police function of output at Chinese patent.Its shortcoming is that infrared ray has directivity, can not walk around the active pedestrian in ward and maybe can not pass opaque shelter.Placement direction to alarm also has requirement, and can only transmit by one-way data, makes it have significant limitation in use.
