Description
Technical field
This utility model relates to medical instruments field, is specifically related to a kind of blood purification blood volume monitoring and is
System.
Background technology
In blood purification treatment, removing the most unnecessary moisture is that a very important treatment refers to
Mark.Blood cleaning equipment needs according to moisture increments in the patient, accurate within the treatment time set
By excessive moisture from removing in the patient.Due to patient individual difference, the speed of dehydration also differs relatively big, when
Rate of water loss is too fast, or patient tolerability is poor, often blood volume in patients will be caused to reduce because of dehydration,
When causing symptomatic hypotension to occur, and with twitching, feel sick, dizzy, have a headache and vomit, only a few is very
To loss of consciousness, jeopardize patient safety.
The method of the blood volume change of blood cleaning equipment measurement at present has two kinds:
A kind of is to measure the ultrasonic speed conducted by blood in arterial blood line and detect the change of density of blood,
Thus calculate the change of relative blood volume.The change of the density of blood can be situated between simply by measuring blood
Sonic velocity change in matter and determine.Glass tubing side ultrasonic launching head sends ultrasonic pulse, by full blood
Glass tubing after arrive opposite side reception head receive, by measure ultrasonic pulse from the conduction being transmitted into reception
Time Calculation goes out the ultrasound wave velocity of sound in blood.Because the velocity of sound and density of blood are directly proportional, it is possible to will
Sonic velocity change is converted to the variable quantity of blood volume.Owing to the program needs the extra consumption increasing by a cuff glass tubing
Material could be checked, so use cost is higher, the patient burden of increase, applies relatively so actual in clinic
Few.
First scheme uses infrared detection, and it is red that its principle is that the RF transmitter by dialysis machine sends
Outside line signal, when hemocyte is by light beam, understands the corresponding infrared ray of how many absorptions according to erythrocyte density,
Unabsorbed infrared ray can be received by the receiver.Because different light energies can be changed by optical-electrical converter
For corresponding voltage signal, system goes out the change of erythrocyte density according to the change calculations of magnitude of voltage.Due to institute
There is object all can launch infrared ray, and the variations in temperature of blood also can cause ultrared change, and then impact
To the measurement of sensor, so this measuring method measurement blood volume variable quantity error is bigger.
Utility model content

Stating light frequency transducer, described light frequency transducer sends to described control after optical signal prosessing becomes frequency signal
Molding block, blood volume in patients change is monitored by described control module by received frequency signal.
When Cleaning Principle of the present utility model is the change of blood volume, density of blood changes, and then impact
The blood absorbance to light.When treatment starts, the output frequency of control module recording light frequency converter
Initial value, compares the frequency values hereafter gathered with initial frequency value, and obtains frequency percentage change,
Control module converts thereof into the variable quantity of blood volume, it is achieved the monitoring to blood volume in patients change.
Further, also include that wave filter, described wave filter are positioned at pipeline and the light frequency of described full blood
Between transducer.Light filters through wave filter after the pipeline of full blood, then by light frequency transducer
Receiving, this makes the optical signal received by light frequency transducer more accurate.
Preferably, described wave filter includes red filter, green filter and blue electric-wave filter, described control
Molding block output control signal controls light frequency transducer and selects described red filter, green filter respectively
And blue electric-wave filter, and calculate the frequency values of output under respective filter respectively.Blood oxygen due to blood of human body
There is larger difference in saturation and blood volume, during blood purification treatment, the color of blood exists the biggest
Difference, according to three primary color theory, any color can be by these 3 kinds of colors of red, green, blue by different ratios
Example mixes, and white light source is made up of three kinds of colors of red, green, blue of equal proportion, red by selection,
The wave filter of green and blue three kinds of colors, measures white light line by the different wave filter after transducer potector
Frequency values, it is possible to measure the color from blood, thus calculate the change of different colours accurately, improves
The adaptability of detection blood color, improves the precision of detection.
When treatment starts, at the beginning of control module recording light frequency converter output frequency under different wave filter
Initial value, compares the frequency values hereafter gathered with corresponding initial frequency value, and obtains the percentage of frequency change
Ratio, then control module converts thereof into the variable quantity of blood volume, it is achieved the monitoring to blood volume in patients change.
Optical signal is filtered by point various filters so that the variable quantity of the blood volume finally given is more accurate,
So that the monitoring to blood volume in patients change is more accurate.
Preferably, described light-emitting device is light emitting diode, and described light emitting diode sends white light.Due to people
There is larger difference in blood oxygen saturation and the blood volume of body blood, during blood purification treatment, blood
There is the biggest difference in color, according to infrared ray and single visible light source, is changed by the blood of different colours
There is larger difference in rate, can be substantially reduced certainty of measurement.And white light can regard three kinds of face of red, green, blue as
The light composition of color, when through wave filter, can improve the precision of detection.
The beneficial effects of the utility model are: this blood purification blood volume monitoring system simple in construction, cost
Low, simple to operate, it is not necessary to extra consumptive material, use original blood purifying pipeline to detect, meanwhile,
This detection scheme will not be disturbed by factors such as blood heat changes, and accuracy of detection is high.
