Under the initial condition, blown down tank 8 is blocked by sliding plate 9, lead to the groove and be located blown down tank 8's right side, a plurality of arcs 4 form cylindricly, pack into casing 1 with the couplant jar prepared in advance, also can insert the couplant bottle with inlet pipe one end, then pull horizontal pole 15 right, horizontal pole 15 drives push pedal 14 and with couplant suction casing 1 intracavity, when push pedal 14 reachs 1 intracavity left end of casing, cover the inlet pipe with the closing cap, it can to loosen horizontal pole 15, the preparation work has been accomplished this moment.

When the device is used, if a couplant needs to be smeared, the device is placed at a position where the couplant needs to be smeared, the device is moved leftwards, in the process of moving leftwards, a gear ring rolls anticlockwise on skin, the gear ring drives an incomplete rack 18 to move leftwards through a gear, when a through groove is communicated with a discharge groove 8 up and down, the couplant is extruded out from the discharge groove 8 under the action of a push plate 14 and a pressure spring, the gear is positioned at a toothless part of the rack 18 at the moment, so that the discharge groove 8 is kept in an open state, meanwhile, the gear ring drives a rotating shaft 2 to roll clockwise through a sun wheel, a plurality of arc-shaped plates 4 form a cylindrical shape, the couplant falls onto the arc-shaped plates 4 from the discharge groove 8, a gap exists between a long strip plate 12 and the arc-shaped plates 4, when the arc-shaped plates 4 pass through the long strip plate 12, the couplant on the arc-, after the arc-shaped plate 4 is contacted with the skin, the couplant on the arc-shaped plate 4 is smeared on the skin; after finishing smearing, pick up this device, sliding plate 9 right under the effect of spring and gear engagement and resume the normal position this moment, and blown down tank 8 is closed once more, and a plurality of arcs resume the normal position under the effect of torsional spring, and a plurality of arcs are cylindricly.

After the ultrasonic examination is finished, the couplant on the skin needs to be wiped, the device moves rightwards on the part needing to be wiped, the gear ring rolls clockwise on the skin, the gear ring is shifted rightwards through the gear until the gear is positioned at a toothless part of an incomplete rack 18, the discharge chute 8 is still blocked by the sliding plate 9 at the moment, the gear ring drives the rotating shaft 2 to rotate anticlockwise through the sun wheel, the movable plate 5 rotates anticlockwise around the hinged part of the movable plate 5 and the annular plate 6 under the shifting of the T-shaped plate 3, one end of the arc-shaped plate 4 is gradually far away from the rotating shaft 2 at the moment, when the arc-shaped plate 4 contacts the skin, the fibers on the arc-shaped plate 4 wipe the couplant on the skin, the couplant on the skin is wiped by the outer side of the arc-shaped plate 4, when the arc-shaped plate 4 passes through the long strip plate 12, one side of the long strip plate 12, the scraped couplant is collected into the container 11 below, after a period of time, the container 11 is pulled forwards, the container 11 is detached, and the container 11 is inserted into the lower end of the vertical plate 10 again after the couplant in the container 11 is cleaned.

The invention has the advantages that:

1. the novel couplant applicator is ingenious in structure, can uniformly apply the couplant to skin, avoids waste, can clean most of the couplant in time after inspection, reduces the use of paper, is simple to operate, and obviously improves the efficiency.

2. The rotating shaft 2 and the gear ring realize coaxial reverse rotation by utilizing the planetary gear train, so that when the couplant is smeared, namely the whole device moves leftwards, the rotating shaft 2 drives the plurality of arc-shaped plates 4 to rotate clockwise, and the couplant is smeared on a region where the device passes through; and when clearing up the couplant, whole device moved right, 2 anticlockwise rotations of pivot this moment, and pivot 2 is kept away from gradually to the one end of arc 4, the centre of a circle of arc 4 no longer coincides with pivot 2, arc 4 has enough big frictional force to skin when skin this moment, make the couplant can be scraped on the arc 4, then in being collected into container 11 by rectangular board 12 again, whole structural design is reasonable, satisfy the demand under the different states.

3. The gear ring is equivalent to a wheel, when the gear ring rolls for one circle on the skin, the rotating shaft 2 rotates for more than one circle, so that sufficient couplant can be remained on the skin when the couplant is smeared, and the same place can be wiped by the arc-shaped plate 4 for many times when the couplant is cleaned, so that the couplant can be wiped cleanly as much as possible.

4. When the couplant on the skin is cleaned, a plurality of parts of the couplant are cleaned and collected, and residual couplant can be cleaned thoroughly only by wiping a small amount of paper or cleaned by clean water.

5. The push plate 14, the cross rod 15 and the pressure spring on the cross rod 15 are combined to extrude the couplant in the shell 1, so that the couplant can smoothly fall down when the discharge chute 8 is opened; by observing the length of the cross bar 15 arranged on the outer part of the shell 1, the residual quantity of the couplant in the shell 1 can be roughly known, and the use is convenient.

6. In the invention, the long strip plate 12 is not contacted with the arc-shaped plate 4 in the smearing process, but the long strip plate 12 can retain the surplus couplant on the arc-shaped plate 4 on the upper end surface of the long strip plate 12, so that the couplant on the arc-shaped plate 4 is evenly smeared on the skin, and in the couplant cleaning process, the long strip plate 12 is contacted with the arc-shaped plate 4, so that the couplant on the arc-shaped plate 4 can be collected.
