Using method of the present invention and the course of work:
(1) 1.8mL capacity narcotic bottle method of operating:
The present invention is connected 220V power supply by 1.11, and power supply indicator 50 is bright;
1.12 insert floor push in floor push socket 8;
1.13 started by press switches 41, start switch indicator 42 is bright, and push rod 12 returns 0 automatically;
1.14 switch on power after, simultaneously started by press switch 41 and duty switch in one minute47, push rod 12 rapidly increases to the top automatically, and automatically stops, and smears with a little medical ventolinAround the top and cushion rubber 13 of push rod 12, prevent medicine bottle glass breaking, also can adopt the method inspectionLook into or change cushion rubber 13;
1.15 press duty switch 47, and the automatic fast-descending to 0 of push rod 12 stops afterwards automatically,Halfway Stopping in injection process, push rod 12 rests on 0 above any position, presses work shapeState switch 47, the automatic fast-descending to 0 of push rod 12 stops afterwards automatically;
1.16 by with the 1.8mL capacity that the installs fiber crops of the matching used disposable use anesthetic tube of the present inventionThe arcotic sleeve 57 of liquor-saturated medicine bottle 56 inserts in arcotic sleeve installing hole 20, under by and revolve counterclockwiseTurn degree more than 90, arcotic sleeve 57 is locked;
1.17 insert the syringe needle of disposable use anesthetic tube and sheath 58 in needle guard jack 40,Carry out preoperative preparation;
1.18 hand-held anesthetic tube handles, with the light pedal switch of pin, one section of distance of push rod 12 fast riseFrom, by the Bas Discharged in anesthetic tube and observe the liquid ejecting, push rod 12 stops automatically, returnsInhale indicator lamp 48 and light, 6 liquid measure indicator lamps 46 are lighted simultaneously, also point of overvoltage prompting indicator lamp 45Bright, now the preparation before injection completes.
1.19 " resorption " test
With the light pedal switch of pin, push rod 12 rises at a slow speed, starts stream at a slow speed, sees that needle point flows out liquid,Lift pin turn-off floor push, push rod 12 automatic rollbacks, now pinpoint inclined plane liquid down drip sucked back,Illustrate that " resorption " function is normal, after push rod 12 rollback certain distances, set back again, " resorption " at onceTest completes;
The light pedal switch of 1.20 use pin, push rod 12 rises at a slow speed, coordinates inserting needle to reach anticipation position simultaneouslyWhile putting, lift pin and turn-off floor push, observe needle handle place and have or not " blood back ", must gently step on if any " blood back "Floor push, in administration at a slow speed, lifts pin after conversion tip position again and turn-offs floor push, observesNeedle handle place has or not " blood back ", in order to upper operation Program viewing, until without " blood back ";
1.21 determine without after " blood back ", and depress floor push, push rod 12 rises and injects at a slow speed,By set time delay automatically enter middling speed, by set time delay enter fast, in push rod 12 rising injection process beforeTop has 6 liquid measure indicator lamps 46 glittering successively, " dose has been injected in instruction ", from 1/6 to 1 liquidAmount indicator lamp 46 " goes out " successively, and liquid measure indicator lamp 46 " entirely goes out " and represents that medicine all noted, rear automaticStop, until stop after sending " the short ring of three sound ", press duty switch 47, push rod 12 certainlyMove and return fast 0, after stopping injecting, will wait and extract again syringe needle in 3 seconds, so that release pressure prevents outWhen pin, have liquid to drop in patient's mouth and cause discomfort, push rod 12 is return after 0, takes off disposable useThe anaesthetic sleeve 57 of anesthetic tube, together with 1.8mL capacity narcotic bottle 56 in cylinder, can renew one againOverlap disposable use anesthetic tube and just can start next operation.
In operating process, as narcotic bottle glass breakage, should lift immediately pin and turn-off floor push, getLower arcotic sleeve 57, pours out cullet by machine, with cotton balls or inhale paper exhaust without after residual liquid,Repeat 1.3 operation.
After start, overvoltage prompting indicator lamp 45 is green, along with the suffered resistance of push rod 12 strengthens, and green lightVariable color gradually has become orange in the time that resistance is increased to 11kg, and while orange lamp is above bright, this opportunityDevice quits work; When after drag reduction lower than 11kg, tangerine lamp above goes out, lamp is below still with green orange,Machine continues normal work.
(2) 2.2mL capacity narcotic bottle method of operating:
2.11 press after 1.8mL capacity narcotic bottle method of operating 1.11-1.15, will be supporting with the present inventionIn the arcotic sleeve 57 of the disposable use anesthetic tube using, install 2.2mL capacity narcotic bottle 59,Again 1.8/2.2mL narcotic bottle crossover sub 11 is connected on to the bottom of anaesthetic sleeve 57, by anaesthetic sleeve57,2.2mL capacity narcotic bottle 59,1.8/2.2mL narcotic bottle crossover sub 11 Trinity, wholeBody inserts in anaesthetic sleeve installing hole 20, under press, be rotated counterclockwise degree more than 90 and lock;
After 2.12 Trinity entirety insertion anaesthetic sleeve installing holes 20 are interior, change-over switch indicator lamp 44Glittering, indication will enter 2.2mL program, but also not exclusively can enter 2.2mL program, now presses and turnsChange switch 43, change-over switch indicator lamp 44 dodges and stops, only bright, formally enters 2.2mL program;
2.13 other are identical with 1.8mL capacity narcotic bottle method of operating 1.17-1.20;
2.14 exit 2.2mL program: by 1.8/2.2mL narcotic bottle crossover sub 11 from anaesthetic sleeveIn installing hole 20, remove, now 44 sudden strains of a muscle of change-over switch indicator lamp, then press change-over switch 43, conversionSwitch indication light 44 goes out, and automatically recovers 1.8ml program.
The machine has 3 kinds of injection speed model selections:
A. after start, when resorption indicator lamp 48 is bright (original start state), depress all the time foot-operated 8 switches,Push rod 12 rises and injects at a slow speed, automatically enters middling speed by setting time delay, enter fast by setting time delay,Constant until send " the short ring of three sound " by this fast forward speed, signal anaesthetic has all been noted, and stops simultaneouslyMachine, presses duty switch 47, and push rod 12 is return 0 automatically fast.
B. by duty switch 47, resorption indicator lamp 48 goes out, and eliminates " resorption " function, depresses pinStep on switch, duty is " often at a slow speed ", only otherwise lifting pin remains jogging speed injection, until send outGo out " the short ring of three sound ", signal anaesthetic has all been noted, and shuts down simultaneously, presses duty switch 47,Push rod 12 is return 0 automatically fast, special procures position and needs this speed. Foot-operated opening lifted out in middle any positionClose, push rod 12 original places stop, then depress floor push, and push rod 12 still continues to move with " at a slow speed ".
C. by duty switch 47, resorption indicates 48 lamps to go out, and eliminates " resorption " function, depresses foot-operatedSwitch, push rod 12 rises and injects at a slow speed, as needs accelerate, after can " lifting and stop " within a secondAt once depress floor push, machine enters fast flow velocity from the inject state of slug flow speed, only otherwise lifting pin beginsKeep eventually fast speed injection, until send " the short ring of three sound ", signal anaesthetic has all been noted, and simultaneouslyShut down, press duty switch 47, push rod 12 is return 0 automatically fast, and most positions need this speedDegree. Floor push is lifted out in middle any position, and push rod 12 original places stop, then depress floor push, topBar 12 still continues to continue (injection) operation with this program.
As needed again " resorption " action, can press again duty switch 47, resorption indicator lamp 48 is bright,Recover to have " resorption " function.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, all at thisWithin the spirit and principle of invention, any amendment of doing, be equal to replacement, improvement etc., all should be included inWithin protection scope of the present invention.
