the SS02 opens the ball valve 20, injects coupling agent into the cylindrical storage barrel 4 through the liquid inlet pipe 19, then closes the ball valve 20, and connects the air inlet pipe 18 with an external air pump through a soft air pipe;

the SS03 enables the controller 23 to control and start the electric telescopic rod 26 by pressing the control button 24, so that the gear rack 10 slides along the inner wall of the C-shaped limiting plate 8, the second rotating gear 9 is driven to rotate, the first rotating gear 7 is driven to rotate, the first curved surface sealing plate 12 and the second curved surface sealing plate 13 synchronously and reversely rotate along the two sliding rails 11 respectively, the leakage hole 17 in the inner wall of the couplant storage chamber 16 is opened, and the couplant flows out through the leakage hole 17;

SS04 makes the gas slowly and uniformly enter the air pressure chamber 15 through each air inlet pipe 18 by controlling the air outlet quantity of the external air pump, the gas presses the diaphragm 14 to deform, thereby slowly pressing the couplant in the couplant storage chamber 16 and accelerating the couplant to flow out through the leakage hole 17;

while SS05 operates SS03 and SS04, medical staff push the connecting handle 40 to drive the smearing roller assembly 1 and the couplant storage assembly 3 to synchronously move along the fixed plate 2, so that the gynecological pregnancy examination couplant is evenly smeared;

after SS06 pregnant examination or the production test, rotate threaded rod 46, drive and scrape liquid subassembly 44 and descend along sliding sleeve 43, support to smearing roller 22 to scraper blade 45 on, rotate annular handle 25, drive and scribble roller 22 and rotate for scraper blade 45 strikes off the remaining couplant of smearing roller 22 week side, scrapes the in-process of getting, and most remaining couplant falls into collection liquid iron box 39 and is collected, and a little couplant on scraper blade 45 passes through the paper handkerchief and wipes.
