The specific embodiment
About aforementioned and other technology contents, characteristics and effect of the present invention, in the following detailed description that cooperates with reference to a graphic preferred embodiment, can clearly present.
Consult Fig. 5 and Fig. 6, the preferred embodiment of ultrasound wave vein checkout gear 1 of the present invention comprises a pulsating ultrasound ripple transmitter unit 21, one ultrasound wave sensing cells 22, one pulsed presser unit 3, one microprocessors 4, and a storage element 5.
Comprise a pulsating ultrasound ripple transmitter unit 21 and a ultrasound wave sensing cell 22 in the ultrasound probe 2, transmitter unit 21 has an agitator of for example being made by piezoelectric, make when transmitter unit 21 is received the driving signal of microprocessor 4, produce a discrete directivity pulsating ultrasound ripple signal.
For purposes of illustration, pulsed presser unit 3 in the present embodiment is that an endless belt 31 and a motor 32 commonly used during with general blood pressure measuring is example, be formed with an air bag (figure does not show) in the endless belt 31, be communicated to motor 32 through a hollow pipe 33, make motor 32 when receiving the instruction of microprocessor 4, can be via the gas in 33 pairs of airbag aerations of hollow pipe or the eliminating air bag.
In the lump with reference to shown in Figure 7, look for the specific body of person under inspection position for example during the venous locations on the arm, at first in step 60 with endless belt 31 bondages of pulsed presser unit 3 to person under inspection's arm.Subsequently in step 61 by microprocessor 4 instruction ultrasonic transmitting elements 21 towards person under inspection's arm, with 10,000 times emitting times each second for example, send for example discrete pulses formula ultrasonic signal of 10MHz; And step 62 by microprocessor 4 simultaneously instruction motor 32 be inflated to rapidly in the air bag, make endless belt 31 apply a pulsed pressure signal to person under inspection's arm.
Because push the blood pressure of pressure in the tremulous pulse that move ahead that blood returns heart in the vein, herein for ease of separating tremulous pulse and vein, when being inflated in the air bag, preferably keep 31 pairs of person under inspection's arms of endless belt applied pressure to be higher than this person under inspection's venous pressure but be lower than person under inspection's diastolic pressure, make when exerting pressure signal, person under inspection's arm vein is blocked fully, advances and artery blood flow is still sustainable.The aspect is obscured for avoiding pressure signal and heartbeat in addition, and pressure signal herein applies speed and also needs to separate with person under inspection's cardiac frequency.
The ultrasound wave sensing cell 22 that is positioned at ultrasound probe 2 is immediately at the echo of step 63 sensing ultrasonic pulse signal, and is converted to signal of telecommunication output.Certainly, echo herein comprises the interface echo of the various different interfaces of human body such as air/skin, blood vessel/blood, muscle/skeleton.
In the step 64, storage element 5 record earlier sends the directivity ultrasonic signal time, and record immediately senses the interval of echo, and writes down received reflected signal.To step 65, by the dobla frequency displacement of microprocessor 4 statistics echos, the reflection echo that the soft tissue amounts such as skeleton, skin and muscle of considering get is a direct current signal that does not become at any time, does not have aforementioned dobla frequency displacement; In addition dobla frequency displacement such as Fig. 8 of arterial blood are relevant with cardiac frequency, and blood flow can't be blocked when being subjected to exerting pressure signal, so the usable reflection of its dobla frequency displacement situation of statistics, the situation that will reflect than vein by force and lasting; Comparatively speaking, the usable reflection of the statistics dobla frequency displacement that venous blood flow produced can be interdependent closely with the pulsed pressure signal.So can be by the having or not of aforementioned pulsed pressure signal, get rid of non-to pip that should the pulsed pressure signal, thereby define pip that should the pulsed pressure signal in step 66, this is the reflection echo of blood in the vein.
At last when step 67, accumulate the repeatedly measurement echo of a period of time as Fig. 9, as previously mentioned, more shallow vein each has its echo pattern with darker tremulous pulse, pattern and kenel according to echo are carried out the aforementioned manner differentiation, to sense this pip echo time and send the ultrasonic signal time and subtract each other by microprocessor 4, acquisition is from transmitting signals to the interval that receives between echo, can extrapolate this pip and launch point spacing divided by the ultrasound wave transmission speed, because the dilatational wave transmission speed of air molecule concussion is about 330m/sec, when but the analytic frequency of the present signal of telecommunication has reached the GHz scope, mean that promptly its spatial resolution the best can reach micrometer range.
Conclude above-mentioned, ultrasound wave vein checkout gear of the present invention, effect by a presser unit, force the blood flow in the vein to produce expected amount of movement variation, cause the dobla frequency displacement of incident ultrasonic echo, thereby venous locations and tremulous pulse and other soft tissue or skeleton are separated, especially adopt the ultrasonic transmitting element of pulsed, detect at specific direction, each time echo can be considered as the record data of time-axis direction, data by the accumulated time axle, look for out the vein position, even if the person under inspection is baby child, or the overweight people, all can obtain the information of vein correct depth easily, unnecessary mistake when avoiding the person under inspection in a single day will have an injection is pricked, so the purpose that structure that the present invention discloses and method can reach this case really.Only the above person only is preferred embodiment of the present invention, can not be only limits scope of the invention process with the exposure of this embodiment; Especially ripely all can understand easily in this skill person, the cumulative data of abovementioned steps 65 to 67, comparison area every, calculate echo reflection point distance etc., almost generation simultaneously when reality measures there is no the sequencing of reality.So the simple equivalent of doing according to the present patent application claim and description changes and modifies generally, all should still belong in the scope that this case patent contains.
