When interviewing division of engineering of naval hospital medicine Head He Shihui, there are two large English books on his desk. He says, he should join the whole army April 8 senior engineer takes an exam. Be in early actually 2002, he has acquired senior engineer title, but army is stricter than the place, it is lifelong that the place gains title competence make, and army should be taken an examination of 5 years completely, passed ability add to allow. Accordingly, the title qualification of army hospital wants reservation to go down, be about " live to be old, take an examination of old " .
Prelusive: From where do you come?
Reporter: Director He still remembers: During Shenzhen cure rich was met last year, when the team of equipment section chief and line of Shanghai cure instrument, team that stride luck has a football match, you are attendant go up kickball, next I am attendant taking a picture piece?
He Shihui: Have bit of impression.
Reporter: One which year do you come to naval hospital?
He Shihui: I reached naval hospital 1991.
Reporter: Come here where are you before?
He Shihui: My college graduate allocated army to take exercise a few years first later, in the Xisha Islands.
Reporter: Sand is a very beautiful place on the west.
He Shihui: It is a very hard place.
Reporter: The what that reads when your university is professional?
He Shihui: What I learn is a radio engineering, be on institute of Taiyuan electron project learn.
Reporter: That is to say, medical treatment equipment do after reaching 421 hospitals from 1991, you just begin a contact?
He Shihui: Be such.
Reporter: Come more than 10 this years, be engaged in equipment maintaining you to think most which kinds of equipment is of expert?
He Shihui: B exceeds, still have biochemical analyzer.
B exceeds: Maintenance and maintain
Reporter: A jest says, a male patient upstairs is taking the examination sheet that female doctor opens to run everywhere downstairs, look for less than is in namely where, asthma runs wheezingly to ask: "Do excuse me 13 exceed where? " female doctor laughs: "What do 13 exceed? It is B exceeds! " patient bate: "You look, what write obviously here is 13 exceed! What write obviously here is 13 exceed!!
He Shihui: (yock) the earliest before A exceeds, a exceeds fell into disuse, undertake checking with B ultrasonic now.
Reporter: Does black and white B surpass the case that the hospital uses now how?
He Shihui: Also be used, because fare is relatively a few lower,black and white B exceeds, general like census, department of gynaecology metropolis is used; But what exceed with colour like heart, hemal examination is some more.
Reporter: Do a black and white B to exceed how many fund should receive commonly?
He Shihui: Be in our hospital, it is probably 40 multivariate.
Reporter: Does colour exceed?
He Shihui: It is previously 200 multivariate, fall now, should 100 multivariate.
Reporter: What principle is B exceeds after all?
He Shihui: The B that uses supersonic pulse echo to check principle with beam scanning implementation namely exceed acoustic imaging technology. Arrive at the echo signal that human body organizes through blasting off, judge the distance of human body viscera and quality time, by force according to monitoring the defer of echo infirmly. The sound frequency that person ear can hear is 20Hz, 20KHz, it is infrasonic sound wave under the sound wave of 20Hz, person ear is unheard, the sound wave of prep above 20KHz is ultrasonic, person ear also is inaudible. Ultrasonic because frequency tall, wavelengh is short, can resemble light in that way the edge travels point-blank, make we can go up to some orient blast off; Ultrasonic is longitudinal wave, travel smoothly in human body organization; The meeting when ultrasonic encounters different medium to hand over a face generates reflection wave, these formed the base that supersonic instrument uses extensively in medical domain.
Reporter: B exceeds appearance to be able to give out ultrasonic, be what to what device will blast off pass?
He Shihui: Pass supersonic probe, this is the crucial part that B exceeds. Supersonic probe interior has a group of supersonic transducer, make by the chip that has piezoelectric effect, this kind of chip that suppress report has special quality, in chip electrify is added to press on specific direction, chip can produce deformation, produce deformation when chip conversely when, correspondence just can produce tension up, realize the changeover of telegraphic date and ultrasonic. The line of chip blast by the past 40, 80, to now 256, 400, line blast more, of image defend oneself rate is higher. The raise that exceeds probe technology content as B and computer handle the buildup of ability, image is met clearer and clearer.
Reporter: When the examination, ultrasonic can cross the place that wants an examination, perhaps arrive at cerebral cortex only merely? Is the frequency of the ultrasonic that probe of that is to say gives out by what to come pilot?
He Shihui: Frequency is OK of set, between million of 2 million ~14, the basis is the organization of human body, fat thin, can undertake adjustment. When the examination, if frequency set forbids, penetrable capability is not strong, affect the exploration of deep organization thereby.
Reporter: Maintenance B exceeds appearance, is bad situation probe is bad comparison much?
He Shihui: Probe is fragile. When the doctor is used, do not take care to fall bad on the ground; Often Lalaila goes, the line inside, outlet falls off; Still have, vacuum is inside, with long mineral oil comes from crust leakage, the reason that probe damages has a lot of.
Reporter: How long can be a probe used commonly?
He Shihui: This does not have a standard, should see a product measure and be used character, the circumstance that maintain. When some people are used, cherish quite, never had fallen, not electrified extract plug, with a few years won‘t bad. Some people are not used, crust split also have. The line of join probe is longer, the attention when using does not break off.
Reporter: Should be the focal point that B exceeds maintenance put on probe?
He Shihui: That is not certain also, should see breakdown happening be in which place. I do maintenance ten years, the B previously transcends line compositive degree not so tall, power source part, signal inputs enlarge to treat part, monitor share, bad can open long, can open even probe will repair. Now of circuit board compositive degree taller, maintenance difficulty will be a few greater. We can judge a breakdown happening where to be, let manufacturer maintain next, manufacturer will maintain also is only that board change went. Little trouble is ourselves will handle, big trouble just lets manufacturer maintain.
Reporter: B exceeds maintain what problem should note?
He Shihui: B exceeds it is very important to maintain at ordinary times, it is the dirt inside the machine wants often clean; 2 it is to should check power source, manostat, often connect electrify to the machine, although be below the case that the machine did not use, also want to let it run; 3 it is to should control indoor temperature and humidity, must keep dry; 4 it is ground wire must have been received, in order to prevent be struck by lightning; 5 it is to should notice electrical wiring is not gnawed to defeat by mice. B exceeds maintaining is to should note these a few problems roughly.
Biochemical analyzer: Actually not complex
Reporter: Opposite B exceeds will tell, does biochemical analyzer want a few more complex?
He Shihui: Say complex, actually not complex. The conduit of biochemical analyzer is very much, basically but from district of canalage, gas, circuit, smooth road a few parts hold.
Reporter: Want to do the maintenance of good biochemistry analyzer, what should the point hold?
He Shihui: The first, want to use clean water with water. We have a deficit with respect to what had taken this side before, you know tap water, foreign matter is much, jam very easily conduit, result electron a powerful person cannot be controlled when to drink water, when to pour water, appeared breakdown, sensor calls the police. We matched water treatment of a diminutive to every machine later machine, have the impurity in water, earth filtering. So, must hold good water quality. The 2nd, the sensor in circuit gives an issue more easily. Sensor basically is automata is in into appearance, reagent be absent, pass, finished, react undertake handling inside the machine. Because control circuit is more, the breakdown that control appears partly is opposite for much dot. If sensor became bad, changing is, the price is not high also. The 3rd, gas district wants pipe to be not defeated only, sealed good, basically do not have what problem.
Reporter: Reagent can be used among this, how to undertake choosing to reagent? What how judge reagent is good with bad?
He Shihui: What reagent uses is good matter to examine accurate inaccurate problem. The reagent that produces formerly may a few more accurate. Home also was opened now. The machine also can be done accuse character, can desired result result forbids definitely truly.
Reporter: Biochemical analyzer is very expensive, a machine child want 10 thousand yuan about a hundred. But my understanding, some manufacturer are willing to offer a machine freely to be used to the hospital, sell reagent next.
He Shihui: Have this kind of case, basically read the class of the hospital, amount of some hospitals specimen is larger, one day can handle on 1000 projects, use reagent more. The price of reagent than ever a few taller, this is equivalent to instalment. There is free lunch on the world, in the long run, machine child free, cost closes from inside reagent. Small hospital, the item is little, reagent makes dosage small, manufacturer is to won‘t send machine child.
Reporter: To different biochemical analyzer, is reagent general?
He Shihui: The reagent previously is private plane appropriative, reagent price refuse to come down. Biochemical analyzer uses reagent now basically is open, homebred reagent machine child can use, but individual machine child reagent or appropriative.
The appeal: Take personnel of education medicine engineering seriously
Reporter: Chairman He got lost management from maintenance now, what maintenance does is little, main job is to do government.
He Shihui: It is some change, but the main task of equipment division is argumentation and maintenance, maintenance is very important one part. The equipment of complete courtyard is more, greatly small, have common (like tonometer) , have high-grade (exceed like resonance of CT, magnetism, B, biochemical analyzer) , it is to want us to maintain.
Reporter: Equipment division does maintenance how many engineer is there?
He Shihui: We made equipment division in the past, army hospital transforms medical engineering division now. Maintenance technician is a bit less now, so I also should participate in maintenance, because I myself get maintenance one‘s previous experience, be in all the time do maintenance.
Reporter: Look Director He is very sentient still to doing maintenance, do not let you do maintenance to still be no good now.
He Shihui: (yock) the major because of me is this respect, oneself major cannot be lost!
Reporter: These ten people of division of our medicine engineering, do not take engineer title series?
He Shihui: Have, we also have series of title of assistant engineer, engineer, senior engineer, army is judged, stricter than the place. The place is lifelong make, we are full take an examination of 5 years, live to be old, acquire old. I myself had been judged 2002 on senior engineer, but force provision is taken an examination of 5 years, ability is OK after been take an examination of add holds the post of. So, I attended the exam of horse and foot even April 8.
Reporter: What to take an examination of? The computer, foreign language and professional class?
He Shihui: Want intermediately to study professional subject, advanced study the computer and foreign language only, computer exam is optional 4 module. Still ask to have scientific research positive result additionally, publish the amount of the paper.
Reporter: How many paper can you publish one year like you?
He Shihui: 3 two of national level. My the year before last year won first prize of innovation of progress of science and technology of Guangzhou military region, have positive result of a scientific research.
Reporter: Achievement of this scientific research very the canal uses, what content be?
He Shihui: The fixed method of equipment of ship vessel medical treatment. Because aboard and land are different, aboard of medical treatment equipment has sway, how be being secured is the problem that we should solve.
Reporter: Basically told large facility (X route aircraft, muti_function shadowless lamp of operation bed, operation) fixed, and temporarily medical treatment equipment (surgery equipment, ICU) fixed. This is contacted with the characteristic photograph of our hospital. I come to this article had looked before.
He Shihui: (laugh) be?
Reporter: The study that other engineers ask it is certain to should attend every year, groom?
He Shihui: Want. I ask our engineer must attend to learn and groom. Compare newlier of knowledge, technology now fast, new knowledge, new technology appears ceaselessly, the technology is more and more advanced. The skill that so we learn did not follow to go up far, if do not learn, rest on one‘s laurels, affirmation can lag behind, do not follow to go up the pace of the development of technical progress and times. So, I often am told to our engineer, acquiring knowledge just is your true original story. What repaired in the past is detached component, each ground is repaired, use iron electric welding; Now is not, present machine child it is compositive change, modular, want to learn to use computer software how to diagnose the place that the machine malfunctions, maintenance follows original different. So, I appeal: Want to value the education of pair of medical engineering personnel!
Reporter: Tell specificly, how to undertake fostering to medical engineering personnel?
He Shihui: The first, improve the professional quality of medical engineering personnel. The hospital is taller and taller to the requirement of medical engineering personnel now, the demand that waits for professional integrated quality to electron, mechanical, medicine is higher and higher also. Medical engineering personnel strengthens major study only, ability enhances the technology of maintenance and ability, get used to this kind of new change. The 2nd, the operation that values medical engineering personnel grooms. When buying new facility, we can invite the engineer of manufacturer undertake operating grooming commonly, want to take this opportunity seriously so. If join an operation won‘t, want to do well maintenance is impossible. The 3rd, the maintenance that attends manufacturer actively to hold grooms class. A lot of manufacturer can do the maintenance that is aimed at some kind of type to groom class, the tutelar appearance maintenance that like the past we attended GE company to hold grooms the class, magnetism resonance maintenance that installs family company to hold grooms class. This kind grooms class specific aim is strong, can explain the knot composition of a picture of specific type, how to judge breakdown, how to maintain, to raising the maintenance of engineering personnel the level has effect very much. When we are buying equipment, groom and after service is to be written into the contract. In guarantee period inside do fortunately, passed to guarantee period the upkeep costs of large facility is very tall, the engineer of manufacturer comes, diagnostic cost 10 thousand multivariate, long do not repair so much money, fittings calculates additionally. So, small issue ourselves can repair repair with respect to oneself. The 4th, attend as far as possible socially groom, delibrate activity. A few major learn to wait for what the organization holds to groom, delibrate activity is very pretty good also, we can attend as far as possible. We are the education that value pair of medical engineering personnel quite, the qualified personnel is very pivotal, doing not have a talent to want to do good maintenance is very difficult.
End: Major cannot be lost
In covering a process, the program that although also talked about equipment,purchases and attend always hind the problem of international invite public bidding, but I always want to change equipment management to this topic, without how Director Shi Hui says hand of their section office is little, he also should participate in the maintenance of a few equipment, "Oneself major cannot be lost! " to him maintenance one‘s own profession is full of the word that has deep love for indefinitely this to touching me deeply, until interview an end very long return the resound in the brain in me.
The lifetime of a person may pursue a variety of professions, perhaps experience distinct post change; An enterprise may manage a variety of products, the product that perhaps manages lies different lifecycle. But, after all which profession just is him love most? Which kinds of product just has core competition capacity?
"Oneself major cannot be lost! " if Director He Shihui is blurted out this sentence, to running life, management company, be need thoughtful issue constantly.
