Description
Technical field
This utility model relates to a kind of blood pressure measuring device, relates in particular to a kind of ambulatory blood pressure measuring device.
Background technology
Blood pressure measuring device mainly is mercurial sphygmomanometer and various electric sphygmomanometer in the market, adopts two kinds of cuff formula or pulse wave conveying types.
Wherein there is following shortcoming in cuff formula measuring device: first; Charge and discharge gas and need a process; So just determined to measure a blood pressure and need spend the long time, the blood pressure signal between twice blood pressure measurement process can't obtain monitoring, and fluctuation of blood pressure signal during this period of time will be omitted.The second, cuff is surrounded on and charges and discharge gas on the arm, especially under frequent situation about measuring even can measured's tissues such as skin be caused damage;
There is following shortcoming in the pulse wave conveying type: first; Pulse wave will be calibrated to different user; Just set up the relation of pulse wave transmission speed and measured's blood pressure, even and same user also need regularly calibrate, to improve the blood pressure measurement precision.But collimation technique existing problems; We calculate the pulse wave transmission speed at the sample pulse wave of tremulous pulse point-to-point transmission; Come to calibrate with the pressure value that recorded through the cuff sphygomanometer at that time; And in using afterwards might squint in the position of sampled point, and so just having a length of vessel is the error of pulse wave transmission range, and it will directly cause the increase of final blood pressure output error.If overcome this error, we need calibrate when each the use; Second; The sampling deficient in stability is because the method for sampling is generally selected the wrist radial artery for use or through photoelectricity volume descriptive method sampling fingertip pulse wave, these activities for human body are relatively more responsive; Therefore require the measured during measuring, to keep static, this is unfavorable for realizing 24 hours dynamic monitoring.
Summary of the invention
The purpose of this utility model is to overcome the deficiency of prior art, and a kind of kinetic measurement blood pressure is provided, and do not have to omit, human body is not produced injury, ambulatory blood pressure measuring device easy to use.
For achieving the above object; The technological means that this utility model adopted is; A kind of ambulatory blood pressure measuring device comprises pulse wave acquisition probe, analog data processing unit, ambulatory blood pressure measurement main body, cuff sphygomanometer, and wherein the pulse wave acquisition probe is selected flexible material for use; And be provided with two groups, be connected on the analog data processing unit through flexible wire respectively; Said analog data processing unit is plugged on ambulatory blood pressure and measures on the main body; The cuff sphygomanometer is plugged on ambulatory blood pressure and measures on the main body.
The operation principle of this utility model: during use, two pulse wave acquisition probe secured in parallel in arm brachial artery place, can be guaranteed simply that the range difference of two tremulous pulse sampled points arrival hearts remains unchanged; Avoided pulse wave transmission range error, then ambulatory blood pressure measured main body, analog data processing unit, through fabrics such as belt fixing with measured's health on; As using for the first time, in the time of perhaps need calibrating, then the cuff sphygomanometer is plugged into ambulatory blood pressure and measures on the main body; Then the cuff sphygomanometer is fixed on by on side person's wrist; Calibrate, after the calibration, remove the cuff sphygomanometer; Just can carry out blood pressure measurement, can carry out 24 hours uninterrupted measurements to the measured like this.
The beneficial effect of this utility model is: two groups of dynamic pulse wave acquisition probe cooperate the cuff sphygomanometer that calibration is once accomplished, and are easy to use; Flexible material design makes the measured not have sense of discomfort, also can not produce injury to measured's stature, and can kinetic measurement in 24 hours, can not produce to measure and omit.
Description of drawings
Below in conjunction with accompanying drawing and embodiment this utility model is further specified.
Fig. 1 is the structural representation of this utility model;
Fig. 2 is that the ambulatory blood pressure of this utility model is measured the agent structure sketch map.
The specific embodiment
Like Fig. 1, Fig. 2; A kind of ambulatory blood pressure measuring device; Comprise pulse wave acquisition probe 101, analog data processing unit 102, ambulatory blood pressure measurement main body 103, cuff sphygomanometer 104; Wherein pulse wave acquisition probe 101 is selected the flexible material pvdf membrane for use, and is provided with two groups, is connected on the analog data processing unit 102 through flexible wire respectively; Said analog data processing unit 102 is plugged on ambulatory blood pressure and measures on the main body 103; Cuff sphygomanometer 104 is plugged on ambulatory blood pressure and measures on the main body 103, in the time of need not calibrating, can directly extract, and does not make the tester produce sense of discomfort; Said ambulatory blood pressure measurement main body 103 comprises the control unit 204 that data acquisition unit 201, data processing unit 202, the data output unit 203 of connection successively have been connected with data processing unit 202; Said data acquisition unit 201 receives the signal that analog circuit unit 102 transmits; Handle and pass to data processing unit 202; After data processing unit 202 is handled the result is outputed to demonstration output on the data output unit 203, control unit 204 connects cuff sphygomanometers 104 and realizes calibration.
During use; At first with two pulse wave acquisition probe 101 secured in parallel in arm brachial artery place, so just can guarantee simply that the range difference that two tremulous pulse sampled points arrive hearts remains unchanged, when left and right sides sampled point symmetry; Sampled point arrives the heart range difference and is determined by heart off-center position degree; And heart off-center degree is a definite value with regard to individual, has just determined that so also the pulse wave transmission time difference is a definite value, has avoided pulse wave transmission range error.Judge whether and to calibrate; If need calibration then to begin calibration process; In most of the cases we have obtained blood pressure and pulse wave transmission time relation equation coefficient; Do not need cuff sphygomanometer 104 to calibrate, then with ambulatory blood pressure measure main body 103, analog data processing unit 102 through fabrics such as belt fixing with measured's health on, can accomplish the measurement of blood pressure dynamically.
Calibration process: worn cuff electric sphygmomanometer 104, so just can begin to carry out the measurement of blood pressure.Earlier cuff sphygomanometer 104 and ambulatory blood pressure being measured main body 103 during calibration is connected; The control unit 204 control cuff sphygomanometers 104 of being measured main body 103 by ambulatory blood pressure carry out blood pressure measurement; Record two characteristic pressure value P0 and P1, analog data processing unit 102 is measured the pulse wave time difference, passes to ambulatory blood pressure and measures main body 103; Obtain blood pressure and pulse wave transmission time relation equation coefficient, so just accomplished primary calibration.
To those skilled in the art, obviously can make various modification and distortion in this utility model scope according to these detailed explanations, description that these are detailed and concrete example only are a kind of explanations but not to the qualification of this utility model.
