Method, not only manpower effectiveness to be increased is low, also can cause maloperation and the error of leakage operation, and quality is collected in impact.Increase visitor
Family unit cost and bring unnecessary loss.
It is currently the collection capacity closely controlling animal blood slurry using the above-mentioned method automatically and manually combining, if so energy
Enough measurement apparatus that an energy real-time detection blood component capacity is installed on blood plasma collecting bottle, and can not connect with blood component
Touch, prevent the pollution section to blood component for the device, certain economic benefit and social effect can be obtained.If so can open
Send out a, do not affected by systematic error and anthropic factor, can accurately detect the measurement apparatus of blood component volume in container, show
Obtain very of far-reaching significance.

Brief description
Fig. 1 is a kind of this utility model blood component volume measurement equipment schematic diagram；
Fig. 2 is a kind of this utility model blood component volume measurement equipment schematic diagram in addition to bottle
Specific embodiment
With reference to specific embodiments and the drawings, this utility model is further described.
In order that the purpose of this utility model, technical scheme and advantage become more apparent, below in conjunction with accompanying drawing and enforcement
Example, is further elaborated to this utility model.It should be appreciated that specific embodiment described herein is only in order to explain
This utility model, is not used to limit this utility model.
If Fig. 1-2 is a kind of embodiment of this utility model blood component volume measurement equipment, a kind of blood component volume
Measurement apparatus, comprising: bottle 5, the bottle mouth position of described bottle 5 equipped with measurement apparatus, described measurement apparatus pass through detection line 2 with
Central processor 1 is connected, and described measurement apparatus include: measurement plug 3, and described measurement plug 3 bottoms have groove 7, in described groove 7
Ultrasound probe 4 is installed, described ultrasound probe 4 is connected with detection line 2, described groove 7 surface is provided with waterproof cover, institute
State bottle 5 and be provided with liquid inlet 6, the height of described liquid inlet 6 is less than the bottleneck height of bottle 5, and described bottle 5 surface sets
There is volume markings value, the material of described measurement plug 3 is elastomeric material, such as quality of rubber materials etc., and described detection line 2 is 0.12mm2's
Flower winding displacement, described ultrasound probe 4 is 10mm(length) * 10mm(width) * 1mm(is thick) and high-frequency ceramic oscillator plate.
Its operation principle is: is the characteristic measuring liquid level using ultrasonic emitting-reflection-record principle.Simple point is said,
Exactly run into material medium back reflection using sound wave in space transmission to return, just can be calculated according to time speed.
1st, the formula of range finding is expressed as: l=c × t
In formula, l is measurement apart from length；
C is the aerial spread speed of ultrasound wave, and being typically referenced to value is 344m/s；
The time difference (t is the half being transmitted into reception time numerical value) that t propagates for measurement distance.
2nd, the measurement height parameter also wanting centering inner treater to be stored before measuring is inputted
Distance=actual liquid level height with the distance-liquid level of popping one's head in of ultrasonic probe to bottom of bottle.
3rd, bonding unit scale calculates the volume v of unit heighth, such as ml/mm
4th, calculate existing liquid capacity:
v= l×vh
Function of the present utility model completes to be to realize measurement function in a device being referred to as detection means.Detection means
First detection plug 3 be used to fixedly mount the effects of ultrasound probe 4 and sealing.Convenience in view of cost and transport
Property, it is changed to common rubber closure when shifting one bottle of blood component.
When there being liquid to enter receiving flask, logical under the pulse signal triggering of the discovery in middle inner treater 1 for the ultrasound probe 4
Cross the ultrasonic pulse that control detection line 2 launches a branch of 2mhz～2.5mhz to bottle 5 bottom direction.Launch one at interval of 20ms
Secondary, to reflection receivable and the reserved enough response times of calculating.When ultrasound probe 4 receives liquid levels, such as blood plasma liquid level
The ultrasound wave reflecting, is converted into 4～20ma current signal, the output of 1～5v voltage signal liquid level, by detection line
It is transferred to central processing unit to be processed.From ultrasonic emitting to again being received, its time with pop one's head in testee
Distance is directly proportional.Electronic unit detects this time, and according to known ultrasonic velocity calculate tested apart from l.It is multiplied by known again
Unit height volume vhCan get liquid capacity at this very moment.Control centre equally will calculate at interval of 20ms
Liquid capacity is compared with aim parameter reason row.When reaching aim parameter, immediately signal is sent by central processing unit and stop composition
Collection.So, the collecting amount of achievable Automatic Control blood component is within ± 5ml.
Due to adopting technique scheme, the beneficial effects of the utility model are: propose a kind of blood component volumetric measurement
