The specific embodiment
As shown in Figure 1, the non-invasive blood sugar monitoring instrument that provides of this utility model by housing 1, be installed in display screen 2, button 3,4,5 on the housing, be installed in the intravital battery of shell 6, two measurement electrode 7,8, capacitance measuring instrument 9, microprocessors 10 constitute.Measurement electrode is installed in housing bottom, and the one end passes housing and contacts with human body skin.A button that is installed in the button of surface of shell can be used as " initiating key ".
As shown in Figure 2, an end of measurement electrode 7,8 passes housing 1, contacts with human body skin, and the other end links to each other with the signal input part of capacitance measuring instrument 9; The signal output part of capacitance measuring instrument 9 links to each other with the signal input part of microprocessor 10; The data output end of microprocessor links to each other with the data input pin of display screen 2.Be installed in the intravital battery 6 of shell and provide working power for whole blood sugar monitoring instrument.
Method and principle that the blood sugar monitoring instrument of the non-invasive that this utility model provides is measured blood sugar for human body are: human body can be taken as a big box that is full of blood, and this box is imagined as electrical equipment, and the electric capacity on its surface can be measured.The variation of blood sugar for human body level can cause the variation of body capacitance amount, particularly, for diabetics, its ante cibum, changes of blood glucose can cause the variation of body capacitance value after meal, and this variation can be measured be come out, so, just can obtain patient's blood sugar level in the middle of one day exactly by the body capacitance amount of measuring diabetics.It should be noted that human body contains electrolyte, as sodium, potassium, chlorine, bicarbonate, blood urea nitrogen and sugar.Except that desaccharide, all other the concentration of electrolyte in blood does not have significant difference after meal in ante cibum, but blood glucose has evident difference after meal in ante cibum, the variation of changes of blood glucose and capacitance is relevant, so ante cibum, measured capacitance can reflect patient's blood sugar level after meal.The present invention is exactly by being installed in the capacitance of the intravital capacitance measuring instrument of this utility model shell, measurement electrode measurement human body current time, then, compare with the capacitance that is stored in a certain blood glucose value of representative in the monitor, thereby calculate the blood glucose value of measured's current time, and show measurement result.
Find electric capacity determinator with 200n two electrode to be placed on human body surface such as forearm, through the experiment inventor just can record the body capacitance amount.
When bringing into use this monitor, user is measured he or she's actual blood glucose by puncturing the finger blood taking method, measures the capacitance of its corresponding skin surface constantly simultaneously, surveys three times or repeatedly; Then, the button 3,4,5 by surface of shell inputs to microprocessor of the present utility model with the data of measuring and seeks out conversion formula.
For example:
Blood sugar level (mg/dl): 80 140 200
Capacitance (n): 2.3 3.2 5.1
When a people's blood sugar level was 80mg/dl, his skin capacitance was 2.3n; When blood sugar level was 140mg/dl, his skin capacitance was 3.2n; When blood sugar level was 200mg/dl, his skin capacitance was 5.1n.The capacitance of skin surface and by a directly relation is arranged between the measured blood glucose value of its finger blood, its conversion formula is as follows:
Y＝KX+B
Y is a glucose concentration level, and K is a design factor, and X is the gained capacitance, and B is blood glucose value curve and X-axis intersection point.
Microprocessor is stored in the constant of this conversion formula in the monitor automatically, and afterwards, the capacitance that the microprocessor in the monitor utilizes this formula to measure at every turn converts corresponding blood glucose value to, shows the blood glucose value of measuring and stores this information.In use after this, as long as touch the button 3 (are initiating key with this button definition), just monitor demonstrates the blood glucose of current time.
This utility model surface of shell has 3 buttons, and first is 3, the second, and to be 4, the three be 5.The blood glucose value of Ce Lianging can be by these three button inputs each time, and the mode of this electronics input data is well-known.
As shown in Figure 1, this utility model can be made the wrist-watch shape, the non-invasive blood sugar monitoring instrument is fixed on bowl portion or near bowl portion by watchband 11, makes two electrodes of monitor touch patient's skin, record the body capacitance value by it and obtain its blood sugar level.
In specific embodiment of the utility model, selected range be 200n, be built-in with microprocessor, the digital capacitance analyzer that has a display screen measures the body capacitance amount and shows the blood glucose value and the corresponding capacitance value of its measurement.Its housing bottom surface is made by plastics or non-conductive material, and two electrodes of its contact skin are the little and sharp metal of 1-2 millimeter.This utility model can be painlessly and can as wrist-watch equally wear in wrist.In the time of the needs of patients measuring blood, only need click " beginning " key (as button 3) simply, blood glucose meter just can be started working, and can in several seconds its blood glucose value at this moment be presented on the screen.
This utility model provides power supply by battery for whole monitor, certainly, also can provide power supply for whole monitor by solar panel.
Fig. 3 carries out 3 blood glucose value measurements accurately, the chart of its blood glucose value and associated electrical capacity for using this utility model to a testee.Fig. 4 measures the chart of its blood glucose value and associated electrical capacity for using this utility model to 3 accurate blood glucose values that the another one volunteer carries out.Pictorialization volunteer's the blood sugar level and the capacitance of its skin surface have the significance relation, and the increase of blood glucose causes the increase of skin surface capacitance.
The utility model has the advantages that: no wound, no pain, it can be worn over wrist or approaching as wrist-watch Wrist by two electrode contact patients' skin, obtains its blood sugar level value by measured capacitance value, More than the employed traumatic blood glucose meter that pain is arranged of other present patient, or complicated infrared ray test macro more Tool superiority and being accepted property are taken the pain of drop of blood with tired thereby avoided puncturing in the present common method finger Disturb. The utility model is simple in structure, easy to use.
