Background technology
Pleural effusion is common symptom clinically, and the calculating of hydrops amount is also often to need the problem solved.The clinical meaning of accurately measuring the pleural effusion amount mainly is the following aspects: 1. utilize the pleural effusion amount of accurately measuring, can accurately understand the pleural effusion growth rate, thereby rib is arranged in the discriminating of clinical good, malignant pleural effusion.2. there is there rib in the clinical judgement (expectant treatment that the pleural effusion therapeutic modality is selected? puncture drainage?).3. have rib in clinical to treatment pleural effusion effect assessment, especially pleural effusion is absorbed to quantitative evaluation.4. a kind of quantitative evaluation means are provided for the pleural effusion related scientific research.And the estimation of traditional iconography pleural effusion amount is accurate not and fuzzy, be unfavorable for the development of related medical and research work, the research of therefore pleural effusion accurately being measured is very important.Make thoracic cavity modeling pleural effusion by oneself by utilization, carry out 64 row VCT Volume rendering technology (VR) pleural effusion is accurately measured to feasibility analysis.
Summary of the invention
For realizing the problems referred to above, it is a kind of simple and quick that the purpose of this utility model is to provide, and can provide tested object accurately for the feasibility that 64 row VCT Volume rendering technology (VR) are accurately measured pleural effusion.
For achieving the above object, the utility model solves the technical scheme that its technical matters adopts: utilize sealed container simulation torso model, put into mould lung simulation human body lungs in it, by electric component (air pump, solenoid valve, rain glass, pipeline etc.) to the gas that rushes certain pressure in the mould lung, make its full and with simulation thoracic cavity inwall, then by submersible pump, solenoid valve, flow sensor, flowmeter, pipeline etc. to injecting the accurately pure water of amount between thoracic cavity inwall, mould lung.
The utility model self-control pleural effusion analogue means further is set to: described simulation torso model adopts airtight plastic material, the approximate circle cone structure, and the mould lung adopts resilient rubber pneumatic bag.
The utility model self-control pleural effusion analogue means further is set to: connecting by pipeline between described electric component, dismantle, install simple and easy.
The utility model self-control pleural effusion analogue means further is set to: described pipeline is silica gel hose, is convenient to putting of device.
The utility model self-control pleural effusion analogue means further is set to: described submersible pump, solenoid valve are also can be controlled manually by the automatic control of controller, air pump, solenoid valve according to the hand-guided of rain glass indicating value, have the step switch of flow indication screen, each electric elements by manually on controller.
The utility model beneficial effect compared with prior art is: can be as required at any time to the increase and decrease of feed liquor amount, mould lung pressure is adjustable, the operation purpose is various, quick, repeatable strong, data read conveniently.

Embodiment
Refer to shown in Figure of description 3, the utility model is a pleural effusion analogue means, and it is simulated thoracic cavity model and Fig. 2 controller and matching component thereof etc. and part by Fig. 1 and forms.
Wherein said simulation thoracic cavity 1 is approximate circle taper closed container, and described mould lung 6, as for wherein, makes the mould lung full through air pump 9 inflations, and rain glass 11 shows force value, unsuitable too high, and 3-5 kPa can make mould lung 6 and thoracic cavity model inwall 2 immediately get final product.
Submersible pump 16 through entering water electromagnetic valve 14, flow sensor 13 from thoracic cavity model water inlet to the thoracic cavity model in water filling, the simulation hydrops, increase along with inflow, hydraulic pressure increases, full mould lung 6 is pushed by water, crushed element breaks away from thoracic cavity inwall 6, then simulates pleural effusion, enters the water yield and is controlled by controller 18 on demand.Finish using, liquid enters water tank 15 by drain solenoid valve 10, after also simulation thoracic cavity 1 can being separated together with ball valve 17, through ball valve 17, discharges liquid.
Rain glass 11 is for showing mould lung 6 internal pressure values.Exhaust solenoid valve 12 is after inflow constantly increases, and during mould lung 6 hypertonia, for mould lung 6 internal pressures, discharges.
The pipeline of connecting components is flexible pipe and is connected with rapid-acting coupling, detachable, installs simple and easy.Can install according to actual conditions.
Example: (water injection rate is 200～1800ml to inject different amount pure water, following and above each water filling of 900ml 10 times, average is 968.50 ± 476.08ml), carry out 64 row VCT scannings, then utilize the AW workstation to carry out CTVR post processing of image measurement self-control thoracic cavity model hydrops amount and the actual injection liquid scale of construction and contrast.
Thoracic cavity feed liquor amount, the mould lung pressure of pleural effusion analogue means of the present utility model are all controlled, and flow indication screen 19 is arranged on controller 18, make this device operation, data acquisition simple and convenient, and to clinical diagnosis, experimental study has very great help.
Above embodiment is only the preferred embodiment of this creation, not in order to limit this creation, any modification of making within all spirit in this creation and principle, is equal to replacement, improvement etc.Within all should being included in the protection domain of this creation.
