Description

Technical Field

[0001] This invention relates to the field of medical technology, specifically to a clinical coupling agent application device. Background Technology

[0002] Medical ultrasound examination is a medical imaging diagnostic technology based on ultrasound waves that visualizes muscles and internal organs—including their size, structure, and pathological lesions. During an ultrasound examination, the air between the probe and the patient's skin will prevent ultrasound waves from entering the body. To obtain high-quality, clear images, a liquid conductive medium is needed to connect the probe to the patient's body surface. This medium is the commonly used ultrasound coupling agent. Medical coupling agent is a medical product composed of a new generation of water-based polymer gel.

[0003] Currently, before undergoing an ultrasound examination, patients need to have coupling gel applied to the examination site. Medical staff usually squeeze the coupling gel from the container and then apply it to the patient's body with their hands or cotton swabs. However, the application of coupling gel may result in uneven application, leading to inaccurate ultrasound probe detection, reduced detection accuracy, and decreased detection efficiency. Furthermore, it is inconvenient for medical staff to control the amount of coupling gel used when squeezing it out, which may result in waste. Summary of the Invention

[0004] This invention addresses the technical problems existing in the prior art by providing a clinical coupling agent application device. This device solves the problem that existing coupling agents may cause uneven application, leading to inaccurate ultrasound probe detection, reduced detection accuracy, and decreased detection efficiency. Furthermore, it addresses the issue that medical personnel may find it inconvenient to control the amount of coupling agent used when applying it, potentially resulting in waste.

[0005] The technical solution of the present invention to solve the above-mentioned technical problems is as follows: a clinical coupling agent application device, comprising a circular tube, wherein an extrusion component is provided at the upper end of the circular tube, an application component and a cleaning component are provided in the middle part of the circular tube, and a protective component is provided at the lower end of the circular tube.

[0006] The beneficial effects of this invention are:

[0007] 1) By setting up an extrusion component and an application component, pressing the handle causes the push plate to press down, squeezing the coupling agent in the round tube into the middle of the threaded column. At the same time, the threaded column moves downward, and under the action of the thread, the threaded column rotates, causing the second mounting plate to rotate, thereby applying the coupling agent. The coupling agent flowing into the second mounting plate is dispersed through the fine holes, preventing uneven application on the second mounting plate. The ball bearings make the application of the coupling agent more even and easier. The handle automatically rebounds after extrusion through the spring. The application amount is accurately controlled by the scale lines to avoid wasting coupling agent, greatly improving the practicality of the device.

[0008] 2) By setting up cleaning and protective components, turning the knob drives the threaded rod to rotate, causing the scraper to move downwards and squeeze the coupling agent remaining in the second storage tank downwards. After the device is used, the protective cover covers the second mounting plate to prevent the second mounting plate from being contaminated with dust and other germs. At the same time, it facilitates the vertical placement of the round tube, and the extension plate prevents the round tube from rolling randomly when it falls, greatly improving the practicality of the device.

[0009] Based on the above technical solution, the present invention can be further improved as follows.

[0010] Furthermore, the coating component includes a first mounting plate, which is slidably connected to the middle of the circular tube. A first storage groove that cooperates with the first mounting plate is opened in the middle of the circular tube. A threaded post is rotatably connected to the lower end of the first mounting plate. The lower end of the threaded post is threadedly connected to the lower end of the circular tube. A threaded hole that cooperates with the threaded post is opened at the lower end of the circular tube. A second mounting plate is provided at the bottom end of the threaded post.

[0011] The beneficial effect of adopting the above-mentioned further solution is that, during the application of coupling agent, as the threaded post moves downward, it rotates under the action of the thread, thereby driving the second mounting plate to rotate, thus applying the coupling agent to the patient's skin surface.

[0012] Furthermore, a partition is fixedly connected to the middle of the second mounting plate, and multiple sets of fine holes are formed in the middle of the partition.

[0013] The beneficial effect of adopting the above-mentioned further solution is that when the coupling agent flows from the lower end of the threaded post into the second mounting plate, the coupling agent is dispersed through the fine holes, so that the coupling agent is evenly distributed when it flows out of the second mounting plate.

[0014] Furthermore, the application assembly also includes ball bearings, and multiple sets of ball bearings are rotatably connected to the lower end of the second mounting plate.

[0015] The advantage of adopting the above-mentioned further solution is that the coupling agent is applied more evenly through the use of ball bearings.

[0016] Furthermore, a spring is sleeved on the outer side of the threaded column, the upper end of the spring is fixedly connected to the first mounting plate, and the lower end of the spring is fixedly connected to the lower inner wall of the first storage groove.

[0017] The beneficial effect of adopting the above-mentioned further solution is that, through the spring, when the first mounting plate is pressed down, the spring is compressed, and when no force is applied, the spring rebounds, so that the first mounting plate and the threaded post automatically return to their positions.

[0018] Furthermore, the upper end of the second mounting plate is fixedly connected to a mounting block, the lower end of the threaded column is threadedly connected to the middle part of the mounting block, and the middle part of the mounting block is provided with a threaded hole that cooperates with the threaded column.

[0019] The advantage of adopting the above-mentioned further solution is that the second mounting plate can be easily disassembled by the mounting block, and it is convenient to add coupling agent into the round tube and clean up residual coupling agent.

[0020] Furthermore, the extrusion assembly includes a push plate, the upper end of the first mounting plate is fixedly connected to the push plate, the upper end of the push plate is fixedly connected to a push rod, and the upper end of the push rod is fixedly connected to a handle.

[0021] The beneficial effect of adopting the above-mentioned further solution is that by pressing the handle, the handle drives the push rod, the push rod drives the push plate, thereby squeezing the coupling agent in the first storage tank. The coupling agent in the first storage tank is squeezed and flows from the outside of the first mounting plate into the threaded column.

[0022] Furthermore, the extrusion assembly also includes scale lines, and scale lines are provided on the front side of the circular tube.

[0023] The advantage of adopting the above-mentioned further solution is that medical personnel can accurately control the amount of coupling agent applied by squeezing through the scale lines.

[0024] Furthermore, the cleaning assembly includes a third mounting plate, the lower end of the threaded column is fixedly connected to the third mounting plate, the middle part of the third mounting plate is rotatably connected to a threaded rod, the upper end of the threaded rod is rotatably connected to the middle part of the push rod, the upper end of the threaded rod is fixedly connected to a knob, the middle part of the threaded rod is threadedly connected to a scraper, the scraper is slidably connected to the middle part of the threaded column, and the middle part of the threaded column is provided with a second storage groove that cooperates with the scraper.

[0025] The beneficial effect of adopting the above-mentioned further solution is that when it is necessary to clean the second storage tank, turning the knob will cause the threaded rod to rotate, which will cause the scraper to move downward, thereby scraping off the residual coupling agent in the second storage tank.

[0026] Furthermore, the protective assembly includes a fourth mounting plate, the lower end of the circular tube is fixedly connected to the fourth mounting plate, the rear side of the fourth mounting plate is rotatably connected to a protective cover, and the left and right sides of the upper end of the circular tube are fixedly connected to extension plates, the length of the extension plates being greater than the diameter of the fourth mounting plate.

[0027] The beneficial effect of adopting the above-mentioned further solution is that when the device is used up, the protective cover can be rotated to cover the second mounting plate, thereby preventing the second mounting plate from getting dusty or dirty. At the same time, it is convenient to place the round tube vertically. When the round tube falls, the extension plate will prevent the round tube from rolling. Attached Figure Description

[0038] The principles and features of the present invention are described below with reference to the accompanying drawings. The examples given are only for explaining the present invention and are not intended to limit the scope of the present invention.

[0039] Medical coupling agent is a medical product composed of a new generation of water-based polymer gel. It has a neutral pH value, is non-toxic and harmless to the human body, does not easily dry out or become rancid, provides clear ultrasound imaging, has suitable viscosity, is non-greasy, allows the probe to slide easily, can moisten the skin, eliminate air on the skin surface, has good lubrication properties, and is easy to deploy; it does not corrode or damage the ultrasound probe; ultrasound coupling agents with bactericidal and disinfecting functions have appeared on the market, which are more stringent in terms of production environment and have a wider range of applications compared to traditional ordinary coupling agents.

[0040] After conducting in-depth investigation and research on the process of applying coupling agent in ultrasound testing, the inventors discovered that uneven application of coupling agent can lead to inaccurate ultrasound probe detection, reducing the accuracy of the test and affecting the testing efficiency. Furthermore, it is inconvenient for medical personnel to control the amount of coupling agent used when squeezing it, which may result in waste. To address these issues, the inventors proposed a clinical coupling agent application device.

[0041] The present invention provides the following preferred embodiments.

[0042] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8 As shown, a clinical coupling agent application device includes a circular tube 1. The upper end of the circular tube 1 is provided with a squeezing component, the middle part of the circular tube 1 is provided with an application component and a cleaning component, and the lower end of the circular tube 1 is provided with a protective component. The coupling agent is squeezed out of the circular tube 1 by the squeezing component, applied to the patient's skin by the application component, and residual coupling agent is cleaned by the cleaning component. The protective component prevents the application end of the application component from being contaminated.

[0043] In this embodiment, as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7As shown, the application assembly includes a first mounting plate 211. The first mounting plate 211 is slidably connected to the middle of the circular tube 1. A first storage groove 212 that cooperates with the first mounting plate 211 is opened in the middle of the circular tube 1. A threaded post 213 is rotatably connected to the lower end of the first mounting plate 211. The lower end of the threaded post 213 is threadedly connected to the lower end of the circular tube 1. A threaded hole that cooperates with the threaded post 213 is opened at the lower end of the circular tube 1. A second mounting plate 214 is provided at the bottom end of the threaded post 213. During the application of coupling agent, as the threaded post 213 moves downward, it rotates under the action of the thread, thereby driving the second mounting plate 214 to rotate, thereby applying the coupling agent to the patient's skin surface.

[0044] In this embodiment, as Figure 2 , Figure 4 and Figure 8 As shown, a partition 215 is fixedly connected to the middle of the second mounting plate 214. Multiple sets of fine holes 216 are opened in the middle of the partition 215. When the coupling agent flows from the lower end of the threaded post 213 into the second mounting plate 214, the coupling agent is dispersed through the fine holes 216, so that the coupling agent is evenly distributed when it flows out of the second mounting plate 214.

[0045] In this embodiment, as Figure 1 , Figure 2 , Figure 4 and 5 As shown, the application assembly also includes ball bearings 217. Multiple sets of ball bearings 217 are rotatably connected to the lower end of the second mounting plate 214. The ball bearings 217 make the coupling agent more evenly applied.

[0046] In this embodiment, as Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, a spring 218 is sleeved on the outer side of the threaded post 213. The upper end of the spring 218 is fixedly connected to the first mounting plate 211, and the lower end of the spring 218 is fixedly connected to the lower inner wall of the first storage groove 212. When the first mounting plate 211 is pressed down, the spring 218 is compressed. When no force is applied, the spring 218 rebounds, so that the first mounting plate 211 and the threaded post 213 automatically return to their original positions.

[0047] In this embodiment, as Figure 4 and Figure 5 As shown, the upper end of the second mounting plate 214 is fixedly connected to the mounting block 219, and the lower end of the threaded post 213 is threadedly connected to the middle of the mounting block 219. The middle of the mounting block 219 has a threaded hole that mates with the threaded post 213. The mounting block 219 facilitates the disassembly of the second mounting plate 214, and makes it easy to add coupling agent to the round tube 1 and clean up residual coupling agent.

[0048] In this embodiment, as Figure 1 , Figure 2 , Figure 3 , Figure 5 and Figure 7 As shown, the extrusion assembly includes a push plate 311. The upper end of the first mounting plate 211 is fixedly connected to the push plate 311, and the upper end of the push plate 311 is fixedly connected to the push rod 312. The upper end of the push rod 312 is fixedly connected to the handle 313. By pressing the handle 313, the handle 313 drives the push rod 312, and the push rod 312 drives the push plate 311, thereby extruding the coupling agent in the first storage groove 212. The coupling agent in the first storage groove 212 is extruded and flows from the outside of the first mounting plate 211 into the threaded column 213.

[0049] In this embodiment, as Figure 1 As shown, the extrusion assembly also includes a scale line 314. The scale line 314 is provided on the front side of the round tube 1. Through the scale line 314, medical personnel can accurately control the amount of coupling agent applied by extrusion.

[0050] In this embodiment, as Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, the cleaning assembly includes a third mounting plate 411. The lower end of the threaded post 213 is fixedly connected to the third mounting plate 411. A threaded rod 412 is rotatably connected to the middle of the third mounting plate 411. The upper end of the threaded rod 412 is rotatably connected to the middle of the push rod 312. A knob 413 is fixedly connected to the upper end of the threaded rod 412. A scraper 414 is threadedly connected to the middle of the threaded rod 412. The scraper 414 is slidably connected to the middle of the threaded post 213. A second storage groove 415 is provided in the middle of the threaded post 213, which cooperates with the scraper 414. When the second storage groove 415 needs to be cleaned, the knob 413 is turned. The knob 413 drives the threaded rod 412 to rotate, causing the scraper 414 to move downward, thereby scraping off the coupling agent remaining in the second storage groove 415.

[0051] In this embodiment, as Figure 1 , Figure 2 and Figure 4 As shown, the protective assembly includes a fourth mounting plate 511. The lower end of the circular tube 1 is fixedly connected to the fourth mounting plate 511. A protective cover 512 is rotatably connected to the rear side of the fourth mounting plate 511. Extension plates 513 are fixedly connected to both the left and right sides of the upper end of the circular tube 1. The length of the extension plates 513 is greater than the diameter of the fourth mounting plate 511. After the device is used, the protective cover 512 is rotated to cover the second mounting plate 214, thereby preventing the second mounting plate 214 from getting dust or debris. At the same time, it is convenient to place the circular tube 1 vertically. When the circular tube 1 falls, the extension plates 513 prevent the circular tube 1 from rolling.

[0052] It should be noted that, in this embodiment,

[0053] The specific steps for using this invention are as follows:

[0054] In use, first, turn the knob 413. The knob 413 drives the threaded rod 412 to rotate, causing the scraper 414 to move upward and stick to the lower end of the push plate 311. Turn the protective cover 512 to open it. Turn the second mounting plate 214 to remove the second mounting plate 214 from the lower end of the threaded post 213. Place the round tube 1 horizontally and add coupling agent to the second storage groove 415. The coupling agent flows out from the upper end of the threaded post 213 along the second storage groove 415 and finally flows into the first storage groove 212. After adding, install the second mounting plate 214 on the lower end of the threaded post 213.

[0055] Pressing handle 313 causes handle 313 to drive push rod 312, push rod 312 to drive push plate 311, push plate 311 moves downward, squeezing the coupling agent in first storage tank 212 and sending the coupling agent into second storage tank 415 until the coupling agent flows out from the lower end of second mounting plate 214. At this time, the air in the device is completely discharged.

[0056] At this point, the roller 217 is placed against the patient's skin surface, and the handle 313 is pressed again. According to the application requirements, the amount of coupling agent is controlled by the scale line 314. The push plate 311 moves down, causing the threaded column 213 to move down. At the same time, the push plate 311 continuously squeezes the coupling agent into the second storage groove 415. The coupling agent flows down along the second storage groove 415 and finally reaches the second mounting plate 214. After passing through the fine hole 216, it is evenly distributed at the lower end of the second mounting plate 214 and finally adheres to the roller 217. Under the action of the thread, the threaded column 213 rotates, which drives the second mounting plate 214 to rotate. The second mounting plate 214 drives the roller 217 to rotate, thereby applying the coupling agent to the patient's skin surface.

[0057] After application, release handle 313, spring 218 returns, causing first mounting plate 211 to rise, thereby removing second mounting plate 214 from the patient's skin surface. Rotate protective cover 512 to close it and set the device aside.

[0058] When the coupling agent in the first storage tank 212 is used up, there is still coupling agent remaining in the second storage tank 415. Turning the knob 413 causes the threaded rod 412 to rotate, which causes the scraper 414 to move downward, thereby scraping the coupling agent in the second storage tank 415 toward the second mounting plate 214.

[0059] In summary, the beneficial effects of this invention are specifically reflected in its ease of use, better results, control over the amount of coupling agent applied, more even application of the coupling agent, and prevention of contamination of the coupling agent, making it safer and more reliable to use.
