As shown in fig. 1 to 3, the multifunctional couplant applying device for ultrasound department of the present invention at least comprises a housing 7 and a power mechanism. The power mechanism is mounted inside the housing 7, wherein: the power mechanism at least comprises a rotating shaft 12. The rotating shaft 12 is movably mounted inside the housing 7. The bottom of the housing 7 is provided with a number of holes 10 in a through-going manner. A pick 8 is provided in the region of the shaft 12 adjacent the aperture 10. Under the condition that the rotating shaft 12 is acted by external force and rotates around the central axis of the rotating shaft, the poking piece 8 can rotate around the central axis of the rotating shaft 12. As shown in fig. 1, the paddle 8 may preferably be a rectangular parallelepiped plate. Preferably, the pick 8 is at an angle to the shaft 12. For example, when the rotating shaft 12 rotates, the pick 8 rotates around the central axis of the rotating shaft 12 under the driving of the rotating shaft 12, and because there is a certain angle between the pick 8 and the rotating shaft 12, during the rotation of the rotating shaft 12, the side face of the pick 8 that forms an acute angle with the bottom of the housing 7 applies a force along the axial direction of the housing 7 to the couplant inside the storage area i, so that the couplant flows out of the device through the hole 10. Preferably, the housing 7 has a hollow cylindrical shape.

Preferably, the power mechanism further comprises a transmission block 5, wherein: the rotating shaft 12 is provided with threads 6. The transmission block 5 is in threaded connection with the rotating shaft 12 through threads 6. In the case where the transmission block 5 is subjected to an external force, the distance between the transmission block 5 and the first end of the rotation shaft 12 can be increased or decreased in such a manner that the rotation shaft 12 rotates about its central axis. Preferably, the driving block 5 may be rectangular. Preferably, the shaft 12 may be cylindrical. For example, when a force is applied to the transmission block 5 in the axial direction of the rotating shaft 12, since the transmission block 5 is in threaded connection with the rotating shaft 12 through the threads 6, the transmission block 5 is an active part, and the rotating shaft 12 is a passive part, while the transmission block 5 moves in the axial direction of the rotating shaft 12, the rotating shaft 12 can rotate around its central axis due to thread transmission, that is, power is provided for the rotation of the plectrum 8.

Preferably, the bottom of the housing 7 is provided with a hinge block 19. The inside of casing 7 is equipped with cradling piece 3, wherein: the first end of the rotating shaft 12 is hinged with a hinge block 19. The second end of the rotating shaft 12 is rotatably mounted on the support rod 3 in a penetrating manner. A fixing block 11 is arranged on the area of the rotating shaft 12 close to the hole 10. The fixing block 11 is provided with a supporting rod 9. The shifting piece 8 is arranged on the supporting rod 9. Preferably, the hinge block 19 may be cylindrical.

The second end of the spring 4 is connected to a transmission block 5. The transmission block 5 is provided with a first compression bar 2 in a manner of penetrating through the bracket bar 3. In case the first compression bar 2 is subject to an external force, the distance between the transmission block 5 and the first end of the rotation shaft 12 from each other can be reduced in such a way that the rotation shaft 12 rotates around its central axis such that the spring 4 is stretched.

Preferably, in the case where the spring 4 is in a stretched state and the transmission block 5 is not subjected to an external force, the transmission block 5 can be moved to the initial position in such a manner that the spring 4 is contracted and the rotation shaft 12 is rotated about its central axis. For example, when the transmission block 5 is moved such that the distance between the transmission block 5 and the first end of the rotation shaft 12 is reduced to a certain extent, the transmission block 5 needs to be reset for the next round of couplant squeezing, at which time the external force on the transmission block 5 is removed, and the transmission block 5 can be returned to the initial position by the spring 4.

In the case where the movable handle 16 is subjected to an external force, the distance between the transmission block 5 and the first end of the rotation shaft 12 can be increased or decreased. For example, the medical staff may rotate the pick 8 about the central axis of the rotating shaft 12 by applying an external force to the movable handle 16 and transmitting the force to the transmission block 5 through the second compression bar 18, the fixed bar 1, and the first compression bar 2.

Preferably, the housing 7 is provided with a fixed handle 14. The fixed handle 14 is provided with a through groove 13. The interior of the housing 7 is provided with a heating rod 22. Preferably, the through slots 13 may be four. Preferably, the shape of the through slots 13 is adapted to the shape of a human finger. Preferably, the heating rod 22 may be a resistance wire. For example, the couplant may be preheated by the heating rod 22 because the temperature of the couplant is too low due to cold weather, which may cause discomfort to the patient.

Preferably, the casing 7 is provided with a scraper 21. The central axis of the first compression bar 2, the central axis of the second compression bar 18 and the central axis of the shaft 12 are parallel to each other.

Preferably, the housing 7 has a hollow cylindrical shape with one open end, wherein: the open end of the housing 7 is provided with a cap 17. The first compression bar 2 extends through the cap 17.

The arc-shaped design can better enable the device to be attached to the skin of a patient, and can enable the couplant to be smeared more uniformly.

In order to facilitate understanding, the working principle of the multifunctional couplant smearing device for the ultrasonic department of the invention is discussed.

When preparing to apply the couplant to the patient, the cover 17 is opened to add a sufficient amount of the couplant into the storage area i, then the heating rod 22 can be selectively switched on as required to heat the couplant, and then the medical staff holds the fixed handle 14 and the movable handle 16 at the same time and pushes the movable handle 16 to reduce the distance between the fixed handle 14 and the movable handle 16, and simultaneously aligns the end of the housing 7 provided with the hole 10 with the part to be inspected of the patient and continuously moves the device. When the examination is finished, the medical staff holds the device and roughly scrapes off the couplant on the skin of the patient by the scraper 21, and then the couplant is wiped by paper.
