[0002] With changes in modern lifestyles, the incidence of fatty liver disease has been increasing year by year. Fatty liver disease not only affects normal liver function but can also lead to a range of serious health problems, such as cirrhosis and liver cancer. Therefore, timely and accurate testing for fatty liver disease is crucial for its prevention and treatment.

[0003] Currently, there are many clinical methods for detecting fatty liver. Among them, ultrasound examination is widely used in primary care and large-scale screening due to its advantages such as non-invasiveness, no radiation, and relatively high cost-effectiveness. However, existing ultrasound detection devices have many inconveniences in actual use. For example, during ultrasound examination, in order to ensure good acoustic coupling between the ultrasound probe and the skin, a coupling agent needs to be applied to the ultrasound probe. However, the existing coupling agent application methods mostly rely on manual operation. Medical staff need to manually apply the coupling agent to the probe surface before each examination.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0030] See also Figures 1-8 A portable detection device for fatty liver detection includes an upper shell 1 and a lower shell 2, the upper shell 1 and the lower shell 2 are connected by a hinge, and an ultrasonic detector body 3 is installed inside the upper shell 1, and further includes:

[0031] For the specific structure of the coupling agent extrusion assembly 4, please refer to Figure 7 The coupling agent extrusion assembly 4 includes a storage cylinder 41, one end of which is threadedly connected to an end cap 42, an outer surface of which is mounted a micro motor 43, and an inner portion of the end cap 42 is rotatably connected to a screw 44, an outer surface of the screw 44 is threadedly connected to a pressure cap 45, an end surface of the pressure cap 45 is fixedly connected to a plunger 46, a guide rod 47 is inserted into the interior of the pressure cap 45 and the plunger 46, and the other end of the storage cylinder 41 is threadedly connected to an extrusion nozzle 48;

[0032] For the specific structure of the bracket assembly 5, please refer to Figure 4-Figure 6 and Figure 8The bracket assembly 5 includes a connecting ear 51, the interior of the connecting ear 51 is rotatably connected to a support rod 52 through a pin shaft, one end of the support rod 52 is fixedly connected to a semi-annular clamping sleeve 53, the outer surface of the semi-annular clamping sleeve 53 is riveted with a connecting plate 54, one end of the connecting plate 54 is rotatably connected to a collar 55 through a pin shaft, the outer surface of the support rod 52 is fixedly connected to a connecting ear 56, the interior of the connecting ear 56 is rotatably connected to a connecting rod 1 57, one end of the connecting rod 1 57 is rotatably connected to a pin 58, both ends of the pin 58 are rotatably connected to a connecting rod 2 59, and the outer surface of the pin 58 is sleeved with a torsion spring 510, and the bottom end of the connecting rod 2 59 is rotatably connected to a connecting ear 3 511;

[0033] The limit card 6 is fixedly connected to the inner wall of the lower shell 2.

[0034] Furthermore, ear one 51 is fixedly connected to the inner wall of the lower shell 2, ear three 511 is fixedly connected to the inner bottom surface of the lower shell 2, the outer surface of the storage cylinder 41 is clamped with a semi-annular sleeve 53, and the outer surface of the storage cylinder 41 is clamped with a ring 55 near the extrusion nozzle 48. The outer surface of the ring 55 is rotatably connected to two connecting plates 54 through a pin shaft.

[0035] When the entire detection device is not in use, the bracket assembly 5 and the coupling agent extrusion assembly 4 are both stored inside the lower shell 2, and the limit clip 6 is provided to abut against the outer surface of the storage tube 41, thereby fixing the coupling agent extrusion assembly 4. The bracket assembly 5 is provided to support the coupling agent extrusion assembly 4, and the bracket assembly 5 can be folded and stored inside the lower shell 2. The upper shell 1 and the lower shell 2 are connected by a hinge for easy opening and closing. At the same time, a buckle is provided for locking the upper shell 1 and the lower shell 2 after they are closed. A handle is also provided on the outer surface of the lower shell 2. The overall structure allows the various components to be neatly stored when the entire detection device is not in use, thereby facilitating the medical staff to carry it. When the detection device is in use, the upper shell 1 and the lower shell 2 can be separated, and then the support rod 52 can be pulled to drive the semi-annular ferrule 53, which can drive the entire coupling agent extrusion assembly 4 to rotate around the pin connecting the ear 1 51 and the support rod 52. In this way, the bracket assembly 5 can be erected, thereby driving the coupling agent extrusion assembly 4 to flip out from the interior of the lower shell 2.

[0036] Furthermore, the bracket assembly 5 also includes two reinforcing plates 512, one end of the reinforcing plate 512 is riveted to the outer surface of the support rod 52, and the other end of the reinforcing plate 512 is riveted to the outer surface of the connecting plate 54. A through hole is opened inside the support rod 52, and a connecting rod 513 is inserted into the through hole. A short rod 514 is inserted into one end of the connecting rod 513, and the short rod 514 is connected to the support rod 52 through a nut matching the connecting rod 513. The short rod 514 is rotatably connected to the end of the short rod 514 away from the connecting rod 513.

[0037] By providing two reinforcing plates 512 for connecting the connecting plate 54 and the support rod 52, a triangular stable structure can be formed, so that the bracket assembly 5 can more stably support the coupling agent extrusion assembly 4. By providing a connecting rod 513 with threads at both ends thereof, the short rod 514 and the support rod 52 can be connected with matching nuts, which can further increase the stability of the bracket assembly 5. It is worth noting that when the support rod 52 is erected, one side thereof is attached to the inner wall of the lower shell 2, which can limit the flipping angle of the support rod 52.

[0038] Furthermore, one end of the torsion spring 510 abuts against the inner wall of the connecting rod 1 57 , and the other end of the torsion spring 510 abuts against the inner wall of the connecting rod 2 59 . A stopper 591 is fixedly connected to the outer surface of the connecting rod 2 59 near the pin 58 .

[0039] By setting the two ends of the torsion spring 510 to respectively contact the inner walls of the connecting rod 1 57 and the connecting rod 2 59, when the storage tube 41 is no longer stuck by the limit card 6, the torsion spring 510 will unfold the connecting rod 1 57 and the connecting rod 2 59. The set block 591 can limit the maximum unfolding angle of the connecting rod 1 57 and the connecting rod 2 59 to 180 degrees, that is, the connecting rod 1 57 and the connecting rod 2 59 can be connected into an oblique rod, which can be used to support the short rod 514 and the support rod 52, so that the support assembly 5 can remain in an upright state after being unfolded.

[0040] Furthermore, two thin tubes 515 are fixedly connected to the outer surface of the ring 55, and a compression spring 516 is placed inside the thin tube 515. One end of the compression spring 516 abuts against the limit pin 517. A clamping hole 518 is opened through the outer surface of the connecting plate 54, and the clamping hole 518 and the limit pin 517 are clearance-matched.

[0041] When the support assembly 5 is unfolded and erected, the storage tube 41 is toggled to drive the collar 55 to rotate around the axis connected to the connecting plate 54. During the rotation, the collar 55 drives the capillary 515, the compression spring 516 and the limit pin 517 to rotate. When the limit pin 517 contacts the clamping hole 518 on the connecting plate 54, it can be locked into it. This can keep the collar 55 horizontally fixed, thereby keeping the entire coupling agent extrusion assembly 4 in an erected state. At this time, the outlet of the extrusion nozzle 48 is vertically downward, which is convenient for subsequent extrusion of the coupling agent for use. When the two limit pins 517 are pressed at the same time, the compression spring 516 can be withdrawn from the clamping hole 518. This can turn the collar 55 over again, so that the coupling agent extrusion assembly 4 is returned to its original position.

[0042] Furthermore, the output shaft of the micro motor 43 is connected to the screw 44 , the outer surface of the plunger 46 is in contact with the inner wall of the storage tube 41 , one end of the guide rod 47 is fixedly connected to the inside of the end cover 42 , and the coupling agent is stored inside the storage tube 41 .

[0043] By starting the micro motor 43, the screw 44 can be driven to rotate. Since the guide rod 47 is provided to limit and guide the pressure cover 45 and the plunger 46, when the screw 44 rotates, the pressure cover 45 can be forced to move on its outer surface, thereby driving the plunger 46 to move. The plunger 46 presses the coupling agent inside the storage tube 41 and discharges it from the extrusion nozzle 48. The medical staff picks up the ultrasonic probe 11 and places its detection end under the extrusion nozzle 48, so that the extruded coupling agent can be caught and applied to the detection end of the ultrasonic probe 11. It is worth noting that the micro motor 43 also includes a timer connected to it, which can limit the time of each rotation of the micro motor 43, so that the amount of extruded coupling agent can be limited, and the micro motor 43 is a reduction motor with a slow rotation speed, which can slowly extrude the coupling agent.

[0044] Furthermore, a power connection port 7 and a probe connection port 8 are provided on the side of the upper shell 1, and a storage plate 9 is fixedly connected to the inner bottom surface of the lower shell 2. A groove 10 is provided on the top of the storage plate 9, and an ultrasonic probe 11 is inserted into the groove 10. The bottom end of the ultrasonic probe 11 is connected to a probe cable 12.

[0045] By connecting the power cord to the power connection port 7, when the power is turned on, a power button is set on the front of the ultrasonic detector body 3. After turning on the power button, the device is turned on, and then the probe cable 12 is connected to the probe connection port 8. In this way, the ultrasonic probe 11 and the ultrasonic detector body 3 are connected. After the detection end of the ultrasonic probe 11 is coated with coupling agent, the ultrasonic probe 11 can be used to aim at the liver for ultrasonic examination. The ultrasonic image is observed in real time through the display screen set on the front of the ultrasonic detector body 1, so as to find out whether the person being tested has fatty liver problems.

[0046] When in use, first, separate the upper shell 1 and the lower shell 2, take out the ultrasonic probe 11 and the probe cable 12, connect the power connection port 7 to the power cord and press the power button to turn on the ultrasonic detector body 3, connect the probe cable 12 to the probe connection port 8, and connect the ultrasonic probe 11 to the ultrasonic detector body 3; then, pull the support rod 52 to drive the semi-annular ferrule 53, so that the bracket assembly 5 stands up and drives the coupling agent extrusion assembly 4 to flip out from the inside of the lower shell 2. At this time, the torsion spring 510 unfolds the connecting rod 1 57 and the connecting rod 2 59 and the maximum angle is limited to 180 degrees by the stopper 591; then Then, the storage tube 41 is moved to drive the ring 55 to rotate, so that the coupling agent extrusion assembly 4 stands upright and the outlet of the extrusion nozzle 48 is vertically downward; then, the micro motor 43 is started to drive the screw 44 to rotate, and the guide rod 47 is limited and guided to make the pressure cover 45 drive the plunger 46 to move, forcing the coupling agent in the storage tube 41 to be discharged from the extrusion nozzle 48, and the detection end of the ultrasound probe 11 is placed under the extrusion nozzle 48 to receive the coupling agent; finally, the ultrasound probe 11 coated with coupling agent is used to align with the liver for ultrasound examination, and the ultrasound image is observed in real time on the front display screen of the ultrasound detector body 3 to determine whether fatty liver exists.

[0047] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
