Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, relates in particular to a kind of fujinon electronic video endoscope stream pressure control system.
Background technology
Means such as the perspective of medical science utilization now, film making, ultrasound wave, nuclear magnetic resonance, NMR, check and the interior illness of diagnosis body, convenient and swift, but some pathological changes, still must direct observation, just can make a definite diagnosis and treat, the development of excellent mirror, image transmission optical fibre, electron camera technology such as (CCD) makes endoscope obtain using widely.
Development along with endoscope, patent about the endoscope aspect also has a lot, for example the someone has applied for patent " separate type endoscope (97242403.2) ", it discloses a kind of separate type medical endoscope, comprise mirror body, lens barrel, light-conducting system, mirror pipe and instrument channel, the mirror pipe is made up of scope pipe and the outer telescop that the liquid inlet and outlet valve is housed, and the prolongation of liquid, gas passage and instrument channel is made in the gap that forms between interior outer telescop.But the air feed equipment of existing endoscope is fairly simple usually, and directly by the air pump air feed, this plenum system does not have feedback control, and pressure stability is poor.
Summary of the invention
It is stable that this utility model has mainly provided a kind of stream pressure, controls highly sensitive fujinon electronic video endoscope stream pressure control system; Solve existing in prior technology endoscope stream pressure instability, pressure is not allowed manageable technical problem.
Simultaneously, it is a kind of simple in structure that this utility model also provides, and the stream pressure range of choice is big, the fujinon electronic video endoscope stream pressure control system that versatility is good; Solved the little technical problem of stream pressure range of accommodation that exists in the prior art.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: a kind of fujinon electronic video endoscope stream pressure control system, comprise air pump, on air pump, be connected with control system, described control system comprises single-chip microcomputer, one end of single-chip microcomputer is connecting the pressure setting device, and an end is connecting air pump; The other end of air pump is connecting air delivering pipeline, is provided with pressure transducer on air delivering pipeline, and the signal feedback of pressure transducer is given single-chip microcomputer.By pressure setting device setup pressure value, be transferred to single-chip microcomputer, the input value of control air pump, on the pipeline of air pump, connecting pressure transducer, the single-chip microcomputer signal that transmission comes to pressure transducer simultaneously and the signal of pressure setting device compare, pressure sensor signal greater than pressure setting device signal time error signal for just, otherwise for negative, single-chip microcomputer is controlled the air demand size of air pump according to this error signal, regulate air pump output pressure size thereby reach, make the purpose that the two pressure equates substantially.
As preferably, on the air delivering pipeline between air pump and the pressure transducer, be provided with relief valve, relief valve is connecting the outfan of single-chip microcomputer.Relief valve be set be in order to run into the output pipe internal pressure and to raise suddenly, air pump since inertia can not quit work immediately, if when pressure surpasses first permissible value, single-chip microcomputer just sends instruction, allow relief valve open, release the part air, pipeline inner pressure is reduced.Thereby the stability and the practicality of system have been guaranteed.
As preferably, on single-chip microcomputer, be provided with setting pressure display and actual pressure display.The actual pressure display is used for showing the pressure in the output pipe, and the setting pressure display is used for display setting pressure.
As preferably, be connected with alarm at the outfan of single-chip microcomputer.If when pressure had surpassed second permissible value when rising, single-chip microcomputer was just given an order, alarm can notify the user system to be out of order, thereby has improved the safety that system uses.
Therefore, fujinon electronic video endoscope stream pressure control system of the present utility model has following advantage: 1, can effectively control the force value of input, stream pressure is stable, controls highly sensitive; 2, simple in structure, good stability; 3, the stream pressure range of choice is big, and versatility is good, and is safe.
Description of drawings:
Fig. 1 is the structured flowchart of a kind of fujinon electronic video endoscope stream pressure control system of the present utility model.
The specific embodiment:
Below by embodiment, and in conjunction with the accompanying drawings, the technical scheme of utility model is described in further detail.
Embodiment:
As shown in Figure 1, a kind of fujinon electronic video endoscope stream pressure control system comprises air pump 1, is connected with control system on air pump 1, and described control system comprises single-chip microcomputer, and an end of single-chip microcomputer is connecting the pressure setting device, and an end is connecting air pump 1; The other end of air pump 1 is connecting air delivering pipeline 2, is provided with pressure transducer on air delivering pipeline 2, and the signal feedback of pressure transducer is given single-chip microcomputer.Also be provided with relief valve on air delivering pipeline 2, relief valve is by monolithic processor controlled.Simultaneously also be connected with alarm on single-chip microcomputer, it is provided with the display and the actual pressure display of setting pressure.
The operation principle of resistance endoscope stream pressure control system is: during air pump (1) work, pressure transducer is measured the air pressure in the air pump dilivery pipe road, single-chip microcomputer receives the signal that pressure transducer and pressure setting device are sent here, and compare, with the error signal of the two pressure reduction (when pressure sensor signal during greater than pressure setting device signal for just, otherwise for negative) be used for controlling the power supply size of air pump, regulate air pump output pressure size thereby reach, make the purpose that the two pressure equates substantially.When running into the output pipe internal pressure and raise (as interrupting air feed etc.) suddenly, air pump since inertia can not quit work at once, if when pressure surpasses first permissible value, single-chip microcomputer is just given an order, allow relief valve open, release the part air, pipeline inner pressure is reduced.If pressure still continues to rise, when surpassing second permissible value, single-chip microcomputer is given an order, and allows alarm work, and notice user system is out of order.And send halt command, allow air pump quit work.The actual pressure display is used for showing the pressure in the output pipe, and the setting pressure display is used for display setting pressure.
Specific embodiment described herein only is that design of the present utility model is illustrated.This utility model person of ordinary skill in the field can make various modifications or replenishes or adopt similar mode to substitute described specific embodiment, but can't depart from spirit of the present utility model or surmount the defined scope of appended claims.
