Description

Technical Field

[0001] This utility model relates to the field of color ultrasound coupling agent application technology, specifically a convenient color ultrasound coupling agent application device. Background Technology

[0002] Color Doppler ultrasound typically consists of a probe (phased array, linear array, convex array, mechanical sector scan, 3D probe, endoscopic probe, etc.), ultrasound transmitting / receiving circuits, signal processing, and image display. It utilizes Doppler ultrasound technology and the principle of ultrasound echo to simultaneously acquire information on blood flow motion, tissue motion, and image formation of human organs and tissues. It is used for ultrasound imaging, measurement, and blood flow motion information acquisition for clinical ultrasound diagnostic examinations. During a color Doppler ultrasound examination, the doctor will apply a gel-like coupling agent to the probe or the examination site. Medical coupling agent is a water-soluble polymer gel, usually non-toxic and harmless with no obvious side effects, although a very small number of people may be allergic to it. During the examination, the presence of the coupling agent helps eliminate air bubbles on the skin surface, allowing the probe and the examination site to adhere better and more closely, resulting in clearer ultrasound images. The coupling agent also provides good lubrication because its suitable viscosity prevents it from drying out immediately.

[0003] For example, Chinese utility model patent CN221830638U discloses an ultrasonic coupling agent application device, including a storage tank, a feeding plate, a replenishing valve, an automatic feeding device, and an adjustable feeding device. The feeding plate is located inside the storage tank and is inclined towards the center, with gaps between the feeding plates. The replenishing valve is located at the top of the storage tank. The automatic feeding device is located inside the storage tank, and the adjustable feeding device is located inside the storage tank and below the feeding plate. This utility model belongs to the field of coupling agent application technology, specifically referring to an ultrasonic coupling agent application device that provides uniform application and controls the amount of coupling agent used.

[0004] However, existing color Doppler ultrasound coupling agent application devices use an application roller to evenly apply the coupling agent to the skin during use, and the application roller is used on different patients, which leads to unsafe and unhygienic situations.

[0005] Therefore, we propose a convenient color Doppler ultrasound coupling agent application device to solve the above problems. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example 1:

[0023] Please see Figure 1-4 This is the first embodiment of the present invention. The present invention provides a technical solution: a convenient color ultrasound coupling agent application device, including a coupling agent soft bottle 1 and an application head 8. A connecting tube 2 is fixedly connected to the top of the coupling agent soft bottle 1. A fixing ring plate 3 is fixedly connected to the outer surface of the connecting tube 2. Positioning grooves 31 are respectively opened at both ends of the top surface of the fixing ring plate 3. Sliding grooves 32 are respectively opened at both ends of the top surface of the fixing ring plate 3. One end of a spring 4 is fixedly connected to one side of the sliding groove 32. A slider 5 is fixedly connected to the other end of the spring 4. The slider 5 is slidably connected to the sliding groove 32. A locking rod 6 is fixedly connected to the side of the slider 5 away from the spring 4. An L-shaped toggle block 7 is fixedly connected to the top surface of the slider 5 to facilitate the movement of the slider 5.

[0024] A sealing ring 9 is fixedly provided on the bottom surface of the applicator head 8. An annular plate 10 is fixedly connected to the outer surface of the applicator head 8. Positioning rods 11 are fixedly connected to both ends of the bottom surface of the annular plate 10. A slot 111 is opened on one side of the bottom of the positioning rod 11. The bottom of the positioning rod 11 contacts the positioning slot 31. The locking rod 6 engages with the slot 111.

[0025] Example 2:

[0026] Please see Figure 1-4 This is the second embodiment of the present invention. This embodiment is based on the previous embodiment. The bottom surface of the sealing ring 9 contacts the top surface of the connecting tube 2, which improves the sealing performance of the connection between the applicator head 8 and the connecting tube 2.

[0027] L-shaped actuating block 7 slides to connect to fixed ring plate 3.

[0028] A sliding opening 33 is provided on one side of the sliding groove 32, and the sliding opening 33 and the positioning groove 31 are internally connected.

[0029] The lever 6 slides to connect to the sliding port 33.

[0030] Limiting blocks 51 are fixedly connected to both sides of the slider 5, and limiting grooves 321 are opened on both sides of the slide groove 32. The limiting blocks 51 are slidably connected to the limiting grooves 321 to improve the stability of the slider 5 movement and limit the range of movement of the slider 5.

[0031] Example 3:

[0032] Please see Figure 1-4 This is the third embodiment of the present invention. Based on the two embodiments described above, in actual use, when the coupling agent needs to be applied to the patient, the cap on the connecting tube 2 can be unscrewed, and the L-shaped actuating block 7 can be moved to move the slider 5 and the locking rod 6. This causes the slider 5 to compress the spring 4, allowing the locking rod 6 to enter the sliding port 33. The positioning rod 11 at the bottom of the annular plate 10 on the outer surface of the application head 8 is then inserted into the positioning groove 31 on the fixing annular plate 3, ensuring that the sealing ring 9 on the bottom surface of the application head 8 is in close contact with the top surface of the connecting tube 2. Releasing the L-shaped actuating block 7 causes the slider 5 and the locking rod 6 to move under the action of the spring 4, causing the locking rod 6 to spring into the corresponding groove 111. This limits and fixes the positioning rod 11, thus fixing the application head 8 onto the connecting tube 2. The coupling agent is squeezed out of the soft bottle 1 and applied to the skin through the applicator 8. After application, the slider 5 and the locking rod 6 can be moved by moving the L-shaped toggle block 7. This causes the slider 5 to compress the spring 4, which in turn causes the locking rod 6 to move out of the locking groove 111 and into the sliding port 33. This releases the limit on the positioning rod 11 and allows the applicator 8 to be disassembled. The applicator 8 can be installed and fixed by connecting the positioning rod 11 to the positioning groove 31 and the locking rod 6 to the locking groove 111. The coupling agent can then be applied. After application, the applicator 8 can be disassembled to avoid applying the applicator 8 to different patients and improve the safety and hygiene of use. If it is necessary to apply the coupling agent to the next patient, a new applicator 8 can be taken and installed. If it is not needed, the cap can be screwed back onto the connecting tube 2.

[0033] The above are merely specific embodiments of this utility model, but the design concept of this utility model is not limited thereto. Any non-substantial improvements made to this utility model using this concept should be considered as infringing on the protection scope of this utility model.
