Description

Technical Field

[0001] This invention relates to the field of medical devices and ultrasound imaging-assisted technology, specifically to a device for optimizing ultrasound imaging of gastric filling. Background Technology

[0002] Gastric ultrasound is of great value in screening for gastric diseases because it is non-invasive and radiation-free. However, since the stomach is a hollow organ, conventional ultrasound examinations are often affected by gas and stomach contents, making it difficult to clearly visualize the stomach wall structure. Therefore, the "gastric distension method" is widely used clinically, where patients drink a large amount of water or a special contrast agent to fill the stomach cavity, eliminating gas interference and creating a clear acoustic window.

[0003] However, existing gastric filling ultrasound examinations have significant drawbacks in practice: First, in order to expel intestinal gas from the anterior wall of the stomach, doctors need to continuously and forcefully press the patient's abdominal wall with an ultrasound probe, but it is difficult to maintain a constant pressure manually, and pressure fluctuations can easily lead to image flicker and artifacts; Second, for obese patients or deep structures such as the gastric fundus, the depth of manual pressure is often insufficient, resulting in unclear lesions; Third, conventional ultrasound coupling gel is prone to slipping and drying after application, and when the probe applies pressure to the curved surface of the abdominal wall, it is very easy to generate microbubbles at the edges, causing acoustic shadowing and reducing image quality.

[0004] Therefore, those skilled in the art have provided a device for optimizing gastric filling ultrasound imaging to solve the problems mentioned in the background art. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a gastric filling ultrasound imaging optimization device that solves the problems of uneven manual pressing pressure, poor coupling, and inability to adaptively adjust the pressing depth according to image quality.

[0006] To achieve the above objectives, the present invention provides the following technical solution: An ultrasound imaging optimization device for gastric filling includes a fixing strap, an adaptive pressurization component is embedded in the middle of the fixing strap, an acoustic coupling component is connected to the bottom of the adaptive pressurization component, an ultrasound probe adapter module is disposed inside the acoustic coupling component, a main control unit is fixedly connected inside the adaptive pressurization component, and the main control unit is electrically connected to the adaptive pressurization component and the ultrasound host respectively through wires. Through the above technical solution, an overall architecture integrating fixation, pressure, coupling and intelligent control was constructed. The device was stably constrained to the patient's abdominal wall by the fixation strap, which provided the structural basis for the main control unit to drive the adaptive pressure component to perform closed-loop pressure. At the same time, by using the acoustic coupling component and the probe adapter module, stable contact and acoustic connection between the probe and the abdominal wall were achieved.

[0007] Furthermore, the adaptive pressurization component includes a fixed housing, a micro motor, a lead screw, a threaded block, a sliding cylinder, a slider, a guide rail, and a pressure sensor. The fixed housing is embedded in a fixed strap. The micro motor is fixedly installed on the top of the inner wall of the fixed housing. The output shaft of the micro motor is fixedly connected to the lead screw. The lead screw is threadedly connected to the threaded block. The outer side of the threaded block is fixedly connected to the sliding cylinder. A slider is fixedly connected to one side of the threaded block. The inner wall of the fixed housing is provided with a guide rail that is slidably connected to the slider. The pressure sensor is embedded in the bottom of the sliding cylinder. The bottom of the sliding cylinder is connected to an acoustic coupling component through the pressure sensor. Through the above technical solution, the micro motor and lead screw convert the rotational motion into the linear pressurizing motion of the sliding cylinder. The guide rail and slider ensure the stability of the pressurizing process. The pressure sensor at the bottom can collect the pressing force in real time and feed it back to the main control unit, realizing precise control of the pressurizing depth and constant pressure maintenance, effectively reducing the fluctuation of the force of manual pressing.

[0008] Furthermore, the acoustic coupling assembly includes a rigid support ring, a flexible water bladder, and an injection valve. The top of the rigid support ring is fixedly connected to a pressure sensor, the edge of the flexible water bladder is sealed to the bottom of the rigid support ring, the interior of the flexible water bladder is filled with acoustic conductive fluid, and the injection valve is located on the side wall of the rigid support ring and communicates with the interior of the flexible water bladder. The above technical solution utilizes a flexible water bladder filled with acoustic conductive fluid as a coupling medium, which can adaptively conform to the abdominal wall curvature of different patients when under pressure, thus improving the problem of conventional coupling agents easily slipping and drying out. The rigid support ring provides a stable force support point, and the injection valve facilitates the adjustment of the fluid volume in the bladder to maintain a better acoustic coupling state.

[0009] Furthermore, the bottom surface of the flexible water bag is a contact surface that contacts the patient's abdominal wall, and micron-sized micro-venting grooves are arranged in an array on the contact surface. By using the above technical solution, micron-level venting grooves are set on the bonding surface, providing an air outlet channel during the process of the flexible water bladder being pressed against the abdominal wall. This facilitates the removal of tiny air bubbles from the contact surface, reduces the risk of acoustic interference caused by trapped air bubbles, and significantly improves the sound wave penetration rate and imaging clarity.

[0010] Furthermore, the ultrasonic probe adapter module includes a retaining ring, a second guide rail, a guide groove, a locking knob, and an ultrasonic probe. The second guide rail is vertically fixed to the inner side of the rigid support ring. The outer side of the retaining ring has a guide groove that slides and connects with the second guide rail. The locking knob is threaded through the side wall of the retaining ring and abuts against the second guide rail. The retaining ring is used to clamp and fix the ultrasonic probe. Through the above technical solution, the combination of the retaining ring and the locking knob achieves stable clamping and positioning of the ultrasound probe, linking the ultrasound probe with the pressure mechanism and thus freeing the doctor's hands. At the same time, the sliding cooperation between the guide rail and the guide groove allows the doctor to flexibly adjust the initial vertical position of the ultrasound probe according to the patient's body shape before the examination. After locking, the ultrasound probe and the pressure mechanism form a rigid whole. With the pressure feedback control of the adaptive pressure component, it effectively avoids the discomfort caused to the patient by excessive pressure and the damage to the ultrasound probe.

[0011] Furthermore, the main control unit includes a microprocessor and an image analysis module. The input terminal of the microprocessor is connected to the pressure sensor and the video output terminal of the external ultrasound host, and the output terminal of the microprocessor is connected to a micro motor. The image analysis module is used to calculate the grayscale contrast and signal-to-noise ratio parameters of the ultrasound image in real time. Through the above technical solution, a closed-loop control core with dual feedback of image and mechanics was constructed. The image analysis module extracts the signal-to-noise ratio, which reflects the noise level of the image, and the grayscale contrast, which reflects the clarity of the stomach wall layers, as feedback signals in real time. This enables the microprocessor to accurately adjust the feed of the micro motor according to the dynamic changes in image quality, and realizes intelligent control that automatically finds the best pressurization depth based on image quality.

[0012] Furthermore, a pressure display screen and a threshold setting button are embedded on the outside of the main control unit, and both the pressure display screen and the threshold setting button are electrically connected to the microprocessor. The above technical solution provides an intuitive human-computer interaction and safety intervention mechanism. The pressure display screen allows doctors to observe the current pressure level in real time, and the threshold setting button allows doctors to set a safe pressure limit based on the patient's body size and tolerance. This enables the microprocessor to have a forced limit function during the image-driven automatic pressurization process, effectively avoiding the risk of the system over-pressurizing in pursuit of image quality and improving the safety of the examination.

[0013] Furthermore, the two ends of the fixing strap are respectively sewn with a Velcro loop side and a Velcro hook side, and a silicone anti-slip pad is fixedly connected to the inner side of the fixing strap. The above technical solution enables the device to be quickly worn and its tightness adjusted on patients with different waist sizes through the use of Velcro. The inner silicone anti-slip pad increases the friction between the strap and the skin, effectively reducing the sliding displacement of the device during the examination and ensuring the stability of pressure application and scanning.

[0014] This invention provides a device for optimizing ultrasound imaging of gastric filling. It has the following beneficial effects: 1. This invention provides a gastric filling ultrasound imaging optimization device. By setting an adaptive pressurization component and a main control unit, it can automatically adjust the pressurization depth according to the signal-to-noise ratio of the real-time image to expel intestinal gas. This realizes closed-loop pressurization control driven by ultrasound image and avoids fluctuations in the force of manual pressurization and doctor fatigue, significantly improving the imaging stability of the filling gastric wall.

[0015] 2. This invention provides a gastric filling ultrasound imaging optimization device. By setting an acoustic coupling component and a micro-venting channel, it adapts to the curvature of the abdominal wall after being compressed and cooperates with the venting channel to expel tiny air bubbles. This effectively solves the problems of easy slippage of coupling agent and easy sound shadow at the edge in conventional ultrasound examination, and significantly improves the sound wave penetration rate.

[0016] 3. This invention provides a gastric filling ultrasound imaging optimization device. By fixing the probe to the adapter module and linking it with the pressure mechanism, it enables the doctor to perform adaptive pressure scanning while freeing the doctor's hands. This allows the doctor to focus on observing and diagnosing ultrasound images, significantly improving examination efficiency and diagnostic accuracy. Attached Figure Description

Detailed Implementation

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Example 1: like Figure 1-7 As shown, this embodiment of the invention provides a gastric filling ultrasound imaging optimization device, including a fixing strap 1, an adaptive pressurization component 2 embedded in the middle of the fixing strap 1, an acoustic coupling component 3 connected to the bottom of the adaptive pressurization component 2, an ultrasound probe adapter module 4 disposed inside the acoustic coupling component 3, and a main control unit 5 fixedly connected inside the adaptive pressurization component 2. The main control unit 5 is electrically connected to the adaptive pressurization component 2 and the ultrasound host respectively through wires.

[0021] In use, first, the fixing strap 1 is wrapped around the patient's abdomen and secured with the Velcro loops 6 and 7, while the inner silicone anti-slip pad 8 conforms to the skin to prevent slippage. Next, the ultrasound probe 45 is placed into the retaining ring 41. Adjusting the probe's initial vertical position by sliding the retaining ring 41 along the guide rail 2 42 according to the patient's abdominal wall thickness, the locking knob 44 is then tightened to secure it against the guide rail 2 42 for rigid locking. Subsequently, degassed water is injected into the flexible water bladder 32 through the injection valve 33 as an acoustic conductive fluid, causing it to slightly expand. The doctor inputs the patient's tolerable upper limit of safe pressure using the threshold setting button 10. After starting the device, the microprocessor 51 controls the micro motor 22 to drive the lead screw 23 to rotate. The threaded block 24 is guided along the guide rail 27 via the slider 26, causing the sliding cylinder 25 to press down smoothly. The pressure sensor 28 then pushes the acoustic coupling assembly 3 and the probe downwards. During the downward pressure, the flexible water bladder 32 adapts to the abdominal wall curvature, and the micro-venting groove 35 expels air from the contact surface. The image analysis module 52 extracts images from the ultrasound host in real time, calculates grayscale contrast and signal-to-noise ratio, and feeds them back to the microprocessor 51. The microprocessor 51 controls the motor to press down step by step according to the parameter increase, and stops when the parameter reaches the standard. If the pressure sensor 28 detects that the pressure has reached the preset safety limit, the microprocessor 51 will forcibly stop the motor even if the image is not optimal to prevent excessive pressure.

[0022] The adaptive pressurization component 2 includes a fixed housing 21, a micro motor 22, a lead screw 23, a threaded block 24, a sliding cylinder 25, a slider 26, a guide rail 27, and a pressure sensor 28. The fixed housing 21 is embedded in the fixed strap 1. The micro motor 22 is fixedly installed on the top of the inner wall of the fixed housing 21. The output shaft of the micro motor 22 is fixedly connected to the lead screw 23. The lead screw 23 is threadedly connected to the threaded block 24. The outer side of the threaded block 24 is fixedly connected to the sliding cylinder 25. A slider 26 is fixedly connected to one side of the threaded block (24). The inner wall of the fixed housing 21 is provided with a guide rail 27 that is slidably connected to the slider 26. The pressure sensor 28 is embedded in the bottom of the sliding cylinder 25. The bottom of the sliding cylinder 25 is connected to the acoustic coupling component 3 through the pressure sensor 28.

[0023] When the micro motor 22 receives the pressing command from the microprocessor 51, the motor output shaft drives the lead screw 23 to rotate. Since the slider 26 is limited by the guide rail 27 and cannot rotate, the rotational motion of the lead screw 23 is converted into the linear sliding of the threaded block 24 along the guide rail 27, which in turn drives the sliding cylinder 25 to extend or retract, realizing the linear application of pressing force. During the pressing process, the pressure sensor 28 at the bottom collects the interaction force between the sliding cylinder 25 and the acoustic coupling component 3 in real time, and converts the mechanical signal into an electrical signal and feeds it back to the microprocessor 51, providing a mechanical basis for closed-loop control.

[0024] The acoustic coupling assembly 3 includes a rigid support ring 31, a flexible water bladder 32, and an injection valve 33. The top of the rigid support ring 31 is fixedly connected to the pressure sensor 28. The edge of the flexible water bladder 32 is sealed to the bottom of the rigid support ring 31. The interior of the flexible water bladder 32 is filled with acoustic conductive fluid. The injection valve 33 is located on the side wall of the rigid support ring 31 and communicates with the interior of the flexible water bladder 32. The bottom surface of the flexible water bladder 32 is a contact surface 34 that contacts the patient's abdominal wall. Micron-sized micro-venting grooves 35 are arranged in an array on the contact surface 34.

[0025] Before inspection, the flexible water bladder 32 is filled with degassed water through the injection valve 33 and the internal air is emptied before sealing. When the adaptive pressurization component 2 applies downward pressure, the rigid support ring 31 transmits the pressure evenly to the edge. The flexible water bladder 32 deforms under pressure, and the bottom contact surface 34 extends outward to fit the abdominal wall with different curvatures. During this pressure-fitting process, the air originally trapped between the contact surface 34 and the skin is squeezed to the micro exhaust groove 35 and discharged to the outside along the groove, thereby reducing the micro air bubbles at the contact interface.

[0026] The ultrasonic probe adapter module 4 includes a retaining ring 41, a second guide rail 42, a guide groove 43, a locking knob 44, and an ultrasonic probe 45. The second guide rail 42 is vertically fixed to the inner side of the rigid support ring 31. The outer side of the retaining ring 41 is provided with a guide groove 43 that is slidably connected to the second guide rail 42. The locking knob 44 is threaded through the side wall of the retaining ring 41 and abuts against the second guide rail 42. The retaining ring 41 is used to clamp and fix the ultrasonic probe 45.

[0027] When installing the probe, insert the ultrasound probe 45 into the retaining ring 41, and then slide the retaining ring 41 up and down along the second guide rail 42 to adjust the amount of the probe bottom surface protruding relative to the bottom surface of the flexible water bag 32 to accommodate the abdominal wall height difference of patients of different body types; after the position is properly adjusted, tighten the locking knob 44, and its end will tightly abut against the side of the second guide rail 42, using friction to rigidly lock the retaining ring 41 and the probe position, so that the probe moves synchronously with the pressurization mechanism.

[0028] The main control unit 5 includes a microprocessor 51 and an image analysis module 52. The input terminal of the microprocessor 51 is connected to the pressure sensor 28 and the video output terminal of the external ultrasound host. The output terminal of the microprocessor 51 is connected to the micro motor 22. The image analysis module 52 is used to calculate the grayscale contrast and signal-to-noise ratio parameters of the ultrasound image in real time. A pressure display screen 9 and a threshold setting button 10 are embedded on the outside of the main control unit 5. Both the pressure display screen 9 and the threshold setting button 10 are electrically connected to the microprocessor 51.

[0029] During automatic pressurization, the image analysis module 52 continuously receives the video stream from the ultrasound host and extracts the grayscale contrast and signal-to-noise ratio of the current frame image. When these two parameters are lower than the preset threshold, the microprocessor 51 outputs a signal to drive the micro motor 22 to continue pressing down. If the grayscale contrast and signal-to-noise ratio reach the preset threshold, the microprocessor 51 immediately stops the motor and maintains the current pressing pressure. At the same time, if the real-time pressure value detected by the pressure sensor 28 reaches the safety upper limit set by the doctor through the threshold setting button 10, the microprocessor 51 prioritizes the execution of the safety command to forcibly interrupt the pressing action of the motor to prevent excessive pressing. The pressure display screen 9 displays the current real-time pressure value throughout the process.

[0030] The two ends of the fixing strap 1 are respectively sewn with a Velcro loop side 6 and a Velcro hook side 7, and a silicone anti-slip pad 8 is fixedly connected to the inner side of the fixing strap 1.

[0031] After wrapping the fixation strap 1 around the patient's abdomen, tighten it and make the hook and loop side 6 and the hook and loop side 7 stick together to fix it. At this time, the inner silicone anti-slip pad 8 is in close contact with the patient's skin. Utilizing the high friction coefficient of silicone, the overall slippage of the device during the pressure scanning process is reduced.

[0032] Working principle: First, in the untied state, the ultrasound probe 45 is inserted into the holding ring 41, and the probe is slid up and down along the guide rail 42 to adjust to the appropriate initial scanning position. Then, the locking knob 44 is tightened to lock it rigidly, so that the probe is linked with the pressurization mechanism. Then, the fixing strap 1 is wrapped around the patient's abdomen and fixed with Velcro, so that the silicone anti-slip pad 8 is close to the skin to provide anti-slip support. Next, the flexible water bag 32 is filled with degassed water through the injection valve 33, and the upper limit of the safe pressure that the patient can tolerate is set through the threshold setting button 10.

[0033] After the device is started, the microprocessor 51 controls the micro motor 22 to drive the lead screw 23 to rotate. Under the limiting guidance of the guide rail 27 and the slider 26, the threaded block 24 drives the sliding cylinder 25 to press down smoothly. During the pressing down, the flexible water bag 32 adaptively conforms to the curved surface of the abdominal wall, and the micro exhaust groove 35 expels air from the contact surface to reduce the acoustic shadow of air bubbles. During this process, the image analysis module 52 extracts the grayscale contrast and signal-to-noise ratio of the ultrasound image in real time and feeds it back to the microprocessor 51. The microprocessor 51 controls the motor to press down step by step according to the parameter improvement. When the parameter reaches the preset threshold, the pressing stops, realizing automatic depth finding driven by the image. At the same time, the pressure sensor 28 monitors the pressing pressure in real time. If the pressure reaches the set safety limit, even if the image parameters are not optimal, the microprocessor 51 will forcibly interrupt the motor action to prevent excessive pressure, thus ensuring both image quality and the safety of the examination.
