[0025] To better understand the purpose, structure, and function of this utility model, the following description, in conjunction with the accompanying drawings, provides a more detailed account of an ultrasonic coupling agent application device.

[0026] like Figure 1-4 As shown, this utility model discloses an ultrasonic coupling agent application device, comprising a storage shell 1. The storage shell 1 has a liquid storage chamber inside its top end, and a cover plate 3 is detachably connected to the opening at the top of the storage shell 1. A sealing groove 11 is provided at the edge of the opening at the top of the storage shell 1. A sealing edge 15, corresponding to the sealing groove 11, is provided at the bottom of the cover plate 3. The size of the sealing edge 15 matches the size of the sealing groove 11, improving the sealing performance between the cover plate 3 and the storage shell 1 through the cooperation between the sealing edge 15 and the sealing groove 11. The four corners of the cover plate 3 are fixedly connected to the four corners of the top end of the storage shell 1 by screws. Fixing ears are provided at the four corners of both the top end of the storage shell 1 and the four corners of the cover plate 3, and are fixed together by screws, facilitating the disassembly of the cover plate 3 for cleaning and disinfection of the interior of the storage shell 1 and for adding coupling agent. A vertically distributed observation window 4 is provided in the middle of the surface of the storage shell 1, allowing for easy measurement of the amount of coupling agent penetrating the liquid storage chamber.

[0027] A lead screw 12 is rotatably connected to the cover plate 3 via a bearing. A pressure plate 13 is threaded onto the lead screw 12. The pressure plate 13 is slidably connected to the inner wall of the liquid storage chamber. A drive box 5 for driving the lead screw 12 to rotate is provided on the upper surface of the cover plate 3. A handle 6 is also provided on the upper surface of the cover plate 3. A motor and a battery are respectively provided inside the drive box 5. The shaft of the motor is connected to the lead screw 12, and the bottom of the lead screw 12 extends to the bottom of the liquid storage chamber. By starting the motor, the lead screw 12 rotates. A threaded hole for threaded connection with the lead screw 12 is provided in the middle part of the surface of the pressure plate 13, so that the pressure plate 13 moves up and down along the length of the lead screw 12, thereby squeezing the coupling agent downward, so that the coupling agent flows out from the outlet 9. The battery is used to power the motor. A charging port for charging the motor is provided on the drive box 5. A button for controlling the forward and reverse rotation of the motor is also provided on the drive box 5. Vertically distributed limiting grooves 10 are provided on both sides of the inner wall of the liquid storage cavity. Limiting blocks 14 corresponding to the limiting grooves 10 are provided on both sides of the pressure plate 13. The limiting blocks 14 and the limiting grooves 10 are slidably connected vertically. The size of the pressure plate 13 matches the size of the opening of the liquid storage cavity. Through the cooperation between the limiting blocks 14 and the limiting grooves 10, the pressure plate 13 is limited. It is also convenient to quickly insert the pressure plate 13 into the liquid storage cavity when installing the cover plate 3.

[0028] The storage shell 1 has supports 8 on both sides of its bottom, with an application roller 7 rotatably connected between the two supports 8. The bottom of the storage shell 1 has multiple evenly spaced liquid outlets 9, with the application roller 7 located below each outlet 9. A protective sleeve 2 is fitted over the bottom of the storage shell 1, with the application roller 7 and supports 8 located within the sleeve 2. The sleeve 2 can be directly fitted over the bottom of the storage shell 1, providing protection for the application roller when not in use. Furthermore, the two supports 8 are flexible, and their surfaces have through holes that mate with the shaft of the application roller 7. When changing patients, the two supports 8 can be pried open to easily replace the application roller 7, facilitating the application of coupling agent to different patients and preventing cross-infection.

[0029] The working principle of this ultrasound coupling agent application device is as follows: During use, the device is picked up using handle 6, then the protective sleeve 2 is removed. The motor is started, and the application roller 7 contacts the patient's skin where the coupling agent needs to be applied. At this time, the lead screw 12 rotates, causing the pressure plate 13 to slowly move downwards and squeeze the coupling agent, allowing it to flow out through the outlet 9. The flowing coupling agent first drips onto the surface of the application roller. The operator moves the handle 6, allowing the application roller 7 to roll on the patient's skin, ensuring the coupling agent is evenly applied to the patient's skin surface and avoiding over-application and waste. After application, the protective sleeve 2 is placed on the storage shell 1. When the coupling agent inside the storage shell 1 is almost used up, the cover plate 3 can be removed to add more coupling agent.

[0030] It is understood that this utility model has been described through some embodiments, and those skilled in the art will recognize that various changes or equivalent substitutions can be made to these features and embodiments without departing from the spirit and scope of this utility model. Furthermore, under the teachings of this utility model, these features and embodiments can be modified to adapt to specific situations and materials without departing from the spirit and scope of this utility model.
