Description
Technical field
The utility model is related to medical instruments fields, more particularly to a kind of water tank measured for radiotherapy.
Background technology
Tumour radiotherapy has more than 100 years history, it is a kind of side using ionising radiation beta ray therapy malignant tumour
Method.Radiotherapy almost can be used for whole body oncotherapy everywhere, at present China there are about 70% or more tumor patient need into
Row radiotherapy.Since ionising radiation ray naked eyes are invisible, it is necessary to borrow special equipment and carry out qualitative and quantitative measurment, to protect
Demonstrate,prove the precision of tumour radiotherapy.Common ionisation chamber and special radiotherapy measure water tank and carry out Dose Calibration and calibration at present.At present
Most of hospital uses traditional radiotherapy to measure water tank, as utility model disclosed in Patent No. CN 203133284U is special
A kind of profit, radiotherapy measurement water tank, by babinet, ionisation chamber adapter, babinet marker, deep calibration line, water filling linker and puts
Penstock forms.
Conventional radiotheraphy measures water tank defect：1. water depth is observed by tank surface scale, only with gauger individual's meat
Eye observation brings uncertainty for measurement result；2. being adjusting different water depth degree, if gauger is a people, in Jia Shui
Or scale is observed when discharging water while adding water, it is extremely inconvenient.
Utility model content
The utility model provides a kind of water measured for radiotherapy to solve the problems, such as that the above-mentioned prior art is worked as
Case.
To achieve the above object, the utility model uses following technical scheme：
A kind of water tank measured for radiotherapy, including babinet, the babinet are supported by multiple pillars, the babinet one side
Discharge tube is connected, the discharge tube is equipped with Draw off valve, and the bottom of box centre installs pressure sensor, the pressure
Sensor is by connection power supply and the display of connecting wires, and the display is installed on the lateral wall of babinet front, in the babinet
Portion is provided with hollow connecting rod, the one end open of the hollow connecting rod and is pierced by babinet and is located on the outside of babinet, and ionisation chamber is by institute
It states and is accessed at the one end open of hollow connecting rod；One end of the babinet connection water inlet pipe, the other end of water inlet pipe connect water source,
It is provided with water pump on the water inlet pipe.
In above structure, one pressure sensor of installation is hit exactly in the bottom of box, by wire connecting power and display,
Display can real-time display water depth, be accurate to millimeter.Display described in the utility model is common with microprocessor
Display, microprocessor can handle the signal that pressure sensor transmits, the Computing Principle of the specific depth of water
It is as follows：Calculation formula P=ρ gh=F/S, P are pressure, and ρ is water density, and g is acceleration of gravity, and h is water depth, and F is water pressure,
S is pressure sensor force-bearing surfaces product；Water density, acceleration of gravity are known constant, pressure sensor force-bearing surfaces product
Can pressure sensor its own parameter or using measure by way of obtain, water pressure can pass through pressure sensor
It measures, so in above-mentioned calculation formula P=ρ gh=F/S, h=F/ ρ gS, ρ gS are constant, so h relationships proportional to F, therefore
The water pressure F measured according to pressure sensor can acquire water depth h by simply operation, without passing through tank surface scale
Water depth is observed, it is easy to operate, avoid the error of sensing tape.
Further, effective measuring center of the ionisation chamber is aligned with the geometric center of babinet.
Further, the babinet is fabricated using transparent material.
Further, the babinet is cubic shape.
Further, the pillar is set as four.
Further, the display is liquid crystal display, and surface covers one layer of waterproof membrane.
Advantageous effect is：The utility model is by into babinet plus water reaches certain depth, to measure the ray depth
Dosage, compared with standard value, reach the calibration and calibration to ray；During adding water, without. while adding water
Concordant observation scale need to only observe display reading while adding water, simple to operate, avoid and visually observe scale band
The uncertainty come.
Description of the drawings
It, below will be right in order to illustrate more clearly of specific embodiment of the present invention or technical solution in the prior art
Specific implementation mode or attached drawing needed to be used in the description of the prior art are briefly described.In all the appended drawings, similar
Element or part are generally identified by similar reference numeral.In attached drawing, each element or part might not be according to actual ratios
It draws.
Fig. 1 is a kind of structural schematic diagram of the water tank measured for radiotherapy of the utility model；
Reference numeral
Wherein 1 is babinet, and 2 be pillar, and 3 be discharge tube, and 4 be Draw off valve, and 5 be pressure sensor, and 6 be display, and 7 are
Hollow connecting rod, 8 be water inlet pipe, and 9 be water pump.
Specific implementation mode
The utility model is further described with reference to embodiment.
A kind of water tank measured for radiotherapy as shown in Figure 1, including babinet 1, the babinet 1 are supported by multiple pillars 2,
1 one side of the babinet connects discharge tube 3, and the discharge tube 3 is equipped with Draw off valve 4,1 bottom centre installation of the babinet
Pressure sensor 5, the pressure sensor 5 through connecting wires connection power supply and display 6, the display 6 be installed on babinet 1
On the lateral wall of front, the middle part of the babinet 1 is provided with hollow connecting rod 7, the one end open of the hollow connecting rod 7 and is pierced by case
Body 1 is located at 1 outside of babinet, and ionisation chamber is accessed by the one end open of the hollow connecting rod 7；The babinet 1 connects water inlet pipe 8
One end, the other end of water inlet pipe 8 connects water source, water pump 9 is provided on the water inlet pipe 8.
In above structure, one pressure sensor 5 of installation is hit exactly in the bottom of box, passes through wire connecting power and display
Device, display can real-time display water depth, be accurate to millimeter.Display described in the utility model is common with microprocessor
The display of device, microprocessor can be handled the signal that pressure sensor transmits, and the calculating of the specific depth of water is former
Reason is as follows：Calculation formula P=ρ gh=F/S, P are pressure, and ρ is water density, and g is acceleration of gravity, and h is water depth, and F is hydraulic pressure
Power, S are pressure sensor force-bearing surfaces products；Water density, acceleration of gravity are known constant, pressure sensor force-bearing surfaces
Product can pressure sensor its own parameter or using measure by way of obtain, water pressure can pass through pressure sensing
Device measures, so in above-mentioned calculation formula P=ρ gh=F/S, h=F/ ρ gS, ρ gS are constant, so h relationships proportional to F,
Therefore the water pressure F measured according to pressure sensor can acquire water depth h by simply operation, without being carved by tank surface
It spends to observe water depth, it is easy to operate, avoid the error of sensing tape.Water can be added in babinet 1 by opening water pump 9, in radiotherapy
After measurement, water can be released by discharge tube 3 by opening waterproofing valve 4.
