Below utility model is described in further detail:
In use, common three types of pneumothoraxs.For closed pneumothorax, when surveying first pressing, observed 3 minutes, show that pressure value is constant; Tension pneumothorax was observed 3 minutes, and pressure continues to raise; The measuring pressure value of traffic pneumothorax is in 0 move left and right.These can be read from Pressure gauge intuitively, then according to Therapeutic Method, and the options button in the starting pressure adjustment district 15.The type of pneumothorax and gas gross are shown in print result automatically by the corresponding program setting of single-chip microcomputer.
Pleural pressure is measured: by band side opening puncture needle 28, go into extraction thoracic cavity gas pressure behind the thoracic cavity, make the gas pressure buffering through gas-water separation bottle 21, through pick off faint pressure signal is received, it is become the signal of telecommunication, with its amplification.This machine adopts the LF147 integrated circuit to form amplifying circuit 23, and with 1000 times of voltage amplifications, Pressure gauge receives the signal of telecommunication pressure from amplifying circuit, after demarcating, can reflect pleural pressure variation and operating pressure state and startup, stop the demonstration of pressure.Pick off rated operating pressure range is ± 0～100mmH
2O, corresponding output voltage are 0～1mV, and adaptive temperature is at ± 40 ℃.The pairing magnitude of voltage of pressure, it selects the decision by SA1, and four outputs of comparison circuit 24 connect relative trigger circuit 27 respectively.Circuits for triggering are made up of the trigger that 74LS00 constitutes, and for preventing to disturb, wherein an end is pressed+the 5V power supply by resistance, and its output connects the base stage of 3DK7E audion by SA1.The emitter stage of one termination audion of relay coil, another termination+24V, coil two ends inverse parallel diode 2CP21 are used for the lead coil energy.Another audion 3DK2B connects relay indicating light, display lamp usefulness+5V power drives.
The display part, in order to calculate the gas flow of extracting the thoracic cavity out, this machine is demarcated the per second throughput of negative pressure pump.Designed a kind of timing displaing circuit in view of the above, calculated the thoracic cavity by the working time of accumulative total negative pressure pump and discharge gas flow, and show by flow display screen 5.
Selectable controlled pressure: because each patient's lung lesion difference, elastance of lung, lung compliance are incomplete same, the required negative pressure of pulmonary's diastole is also different, for adapting to clinical needs, is made as the machine operating pressure adjustable, adjustable in the physical stress scope, establish ± 0～100mmH
2O forms trigger with 74LS00, connects the forward-backward counter counting, through CD40S1 control starting with stop, connecting charactron simultaneously and shows adjustable pressure numerical value.
Be interrupted aerofluxus: set aerofluxus 2 minutes, stopped 6 fens, circular flow to thoracic cavity gas disappears, and stops at the negative 50mmH of doctor's preliminary election
2O～negative 100mmH
2Between the O.Prevent full lung compressibility pneumothorax and a large amount of hydrothorax patient, because aerofluxus liquid blindly, easily cause pendular movement of mediastinum or opening property edema caused by the lung disorder eye and designing again.
Have a power failure to report to the police and depletion of QI is reported to the police: the tension pneumothorax patient, when power supply stops suddenly, and unmanned when finding to have a power failure, the clinical danger that often easily causes, therefore setting up has a power failure reports to the police, and points out doctor and patient to take urgent measure immediately and sets up.Adopt rechargeable battery, charge during work, in case when having a power failure rechargable battery to musical film power supply report to the police.Depletion of QI is reported to the police: when patient thoracic cavity depletion of QI, pressure pointer 6 stop at that the doctor sets-50～-100mmH
2During the no longer aerofluxus that reaches 40 minutes between the O, sb.'s illness took a favorable turn for the prompting patient, submits to the doctor to check, adopts 555 intervalometers and enumerator, picks up counting to begin when reaching 40 minutes to report to the police when the depletion of QI of thoracic cavity.
Gas injection: used when giving patient pedestrian worker pneumothorax, gas skin.Adopt adjustable in pressure, the machine back side is provided with pressure and indicates special-purpose malleation indicator cock.Front panel has the gas injection switch.
