Description

Technical Field

[0001] The invention relates to the technical field of medical instruments, and in particular to a handheld ultrasonic device which is convenient for operation and observation. Background Art

[0002] With the continuous development of medical technology, ultrasound diagnostic equipment is being used more and more widely in clinical medicine. Ultrasound diagnosis is a non-invasive, painless and convenient medical imaging method that can observe the internal tissue structure and organ function of the human body in real time, providing an important basis for the diagnosis and treatment of diseases. Compared with two-dimensional ultrasound imaging, three-dimensional ultrasound imaging can present three-dimensional anatomical structures. For example, three-dimensional ultrasound imaging is used to perform small-scale examinations of the fetus, heart, blood vessels and other locations. Traditional ultrasound equipment is large in size and complex to operate, and usually requires professional technicians to operate in fixed medical locations, which to a certain extent limits its scope of application and convenience. In recent years, handheld ultrasound equipment has emerged. It has the advantages of small size, light weight, easy to carry and operate, and can be quickly deployed in different medical scenarios, such as emergency rooms, ambulances, medical points in remote areas, etc., greatly improving the accessibility and efficiency of medical services.

[0003] The existing Chinese patent with publication number CN217886048U includes an ultrasonic module, a position sensor, a touch display module and a handheld component. The ultrasonic module includes an ultrasonic transducer, the position sensor is installed on the side of the shell of the ultrasonic module, the touch display module is installed on the upper surface of the shell of the ultrasonic module, and the handheld component is installed on the lower surface of the shell of the ultrasonic module. The two-dimensional ultrasonic image scanned by the ultrasonic transducer and the scanned image obtained after processing the three-dimensional spatial position information sensed by the position sensor are displayed in real time on the touch display module.

[0004] The above-mentioned device is installed on the upper surface of the shell of the ultrasonic module through the touch display module. During detection, the operator scans the part to be detected by holding the handheld component, and then sends the ultrasonic image collected by the ultrasonic module and the position information corresponding to the ultrasonic image collected by the position sensor to the background for processing, and then displays the processed three-dimensional ultrasonic image in real time on the touch display module. However, in actual use, since the touch display module is exposed to the outside for a long time, it is easy to accidentally collide with the outside world, resulting in damage to the touch display module and poor use effect. Therefore, it is difficult to automatically fold and store the touch display module after use.

[0005] To this end, we proposed a handheld ultrasound device that is easy to operate and observe. Summary of the invention

[0011] Preferably, the auxiliary mechanism includes a circular block coaxially fixed to the crank, an internal ratchet is rotatably connected to the outer contour of the circular block, a support groove is opened on the outer contour of the circular block, a pawl that meshes with the inner tooth groove of the internal ratchet is fixedly rotatably connected to the inner wall of the support groove, and a second torsion spring for guiding the pawl to rotate back to its original position is fixedly connected to the opposite surfaces of the two sides of the pawl and the support groove.

[0012] Preferably, a rack for driving the crank to rotate is fixedly connected to one side of the bottom of the T-shaped block close to the inner ratchet, and a toothed ring meshing with the tooth grooves on the rack is fixedly connected to the outer contour of the inner ratchet.

[0013] Preferably, a storage box for storing disinfectant is fixedly connected to one end of the ultrasonic device body far from the T-shaped block, and cylindrical shells are fixedly connected to symmetric positions on both sides of the fixing rod close to the storage box.

Pistons for extracting and discharging the disinfectant inside the storage box are fixedly connected to the ends of the two moving rods far from the T-shaped block. The two pistons respectively penetrate through the inner wall of the adjacent cylindrical shell and are movably connected.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0016] First, the threaded rod rotates axially and reciprocally under the drive of the motor, and the threaded sleeve on the threaded rod is closely matched with it, so that the threaded sleeve drives the T-shaped block to horizontally reciprocate in the moving groove of the fixing plate, which can drive the touch display screen to be flipped and displayed and folded and stored. When the T-shaped block moves towards the direction close to the fixing rod, the touch display screen on it rotates through the pin shaft and gradually flips upward. At the same time, under the push of the T-shaped block, the L-shaped rod pulls the end of the touch display screen far from the T-shaped block to lift upward, and finally the touch display screen reaches an appropriate flipping and displaying angle, which is convenient for medical staff to operate and observe. When the T-shaped block moves back in the direction away from the fixing rod, the touch display screen gradually folds under the support of the L-shaped rod and finally is stored in the inner wall of the rectangular frame. The whole process is stable and precise, avoiding the risk of accidental collision and damage of the touch display screen with the outside world, improving the convenience and comfort of operation, and significantly enhancing the durability of the device, reducing the maintenance cost and equipment downtime caused by the damage of the display screen.

[0017] Second, through the cooperation of components such as the crank, circular block, internal ratchet, and pawl in the auxiliary mechanism with structures such as the rack, moving frame, and cleaning plate, it is possible to drive the cleaning plate to comprehensively clean the dust and fingerprints on the surface of the touch display screen after the touch display screen is folded and stored. Compared with the traditional manual cleaning method, it saves the time and energy of medical staff and improves the cleaning efficiency; it can ensure the uniformity and thoroughness of cleaning, avoid problems such as blurred image display caused by incomplete cleaning, so as to ensure that the touch display screen is always in good working condition, provide clear and accurate image information for medical staff, and help improve the accuracy of diagnosis.

[0018] Third, a disinfectant extraction and discharge system is jointly constituted by a piston plate, a moving rod, a cylindrical shell, a drain pipe, a liquid inlet pipe, a one-way drain valve, a one-way liquid inlet valve, etc. When the T-shaped block reciprocates horizontally, it drives the piston plate to reciprocate axially in the cylindrical shell. By using the change of the air pressure inside the cylindrical shell and through the control of the one-way liquid inlet valve and the one-way drain valve, the disinfectant in the storage tank is quantitatively extracted and discharged to the inner wall of the cleaning plate, and the disinfectant can wet the sponge block in the cleaning plate. Furthermore, the sponge block on the cleaning plate can evenly apply the disinfectant when wiping the surface of the touch display screen, so as to disinfect the touch display screen, effectively solving the problem that when the existing handheld ultrasonic device is used by multiple people and medical staff operate the touch display screen manually, fingerprints and bacteria on the hands are easily left on the surface of the touch display screen, resulting in cross-infection, improving the hygiene and safety performance of the device, and being particularly suitable for scenarios with high requirements for hygiene and disinfection in the medical environment.

[0019] Through the combined use of the above structures, the problem that in the actual use process of the existing device, due to the long-term exposure of the touch display module to the outside, it is prone to accidental collisions with the outside, resulting in damage to the touch display module and poor use effect, and thus it is difficult to automatically fold and store the used touch display module is solved.

And a sponge block provided on the cleaning plate 12 enables the sponge block to be in contact with the surface of the touch display screen 5, so as to facilitate subsequent cleaning of dust and fingerprints on the surface of the touch display screen 5.

[0046] Through the active block 14 provided on the moving frame 11 and the crank 13 provided on the fixed plate 3, the crank 13 can support the position of the moving frame 11 under the action of the active block 14.

Through the auxiliary mechanism provided on the crank 13, the auxiliary mechanism can drive the cleaning plate 12 to move and comprehensively clean dust and fingerprints on the surface of the touch display screen 5, improving the cleaning effect of the cleaning plate 12.

[0047] Embodiment 4:

[0048] On the basis of Embodiment 3, furthermore:

[0049] The auxiliary mechanism includes a circular block 16 coaxially fixedly connected to the crank 13. An internal ratchet 17 is rotatably connected to the outer contour of the circular block 16. A support groove 161 is formed on the outer contour of the circular block 16. A pawl 18 meshing with the inner tooth groove of the internal ratchet 17 is fixedly connected to the inner wall of the support groove 161 by a fixed axis. Second torsion springs 19 for guiding the pawl 18 to rotate back to its original position are fixedly connected to the opposite surfaces of both sides of the pawl 18 and the support groove 161.

[0050] On one side of the bottom of the T-shaped block 4 close to the internal ratchet 17, a rack 20 for driving the crank 13 to rotate is fixedly connected. A toothed ring 21 meshing with the tooth groove on the rack 20 is fixedly connected to the outer contour of the internal ratchet 17.

[0051] In use, through the circular block 16 provided on the crank 13, the circular block 16 can be coaxially fixed to the crank 13, and the internal ratchet 17 provided on the circular block 16 enables the internal ratchet 17 to be rotationally connected to the outer contour of the circular block 16.

[0052] As Figure 3 , Figure 4 , Figure 5 and Figure 8 shown, when the T-shaped block 4 moves towards the fixed rod 7 to flip and display the touch display screen 5, the T-shaped block 4 can synchronously push the rack 20 to be meshed with the teeth on the toothed ring 21 and move horizontally. At this time, the toothed ring 21 can drive the internal ratchet 17 to rotate on the outer contour of the circular block 16 under the push of the rack 20, and the pawl 18 slides with the tooth groove in the internal ratchet 17, while the crank 13 remains stationary. When the T-shaped block 4 moves back towards the direction away from the fixed rod 7 and drives the touch display screen 5 to be folded and stored, at this time, the pawl 18 is engaged with the tooth groove in the internal ratchet 17, so that the toothed ring 21 can drive the circular block 16 to rotate through the internal ratchet 17 under the pull of the rack 20, and the circular block 16 is coaxially fixed to the crank 13. Thus, the circular block 16 can drive the end of the crank 13 away from the first torsion spring 15 to rotate towards the direction close to the T-shaped block 4, then the first torsion spring 15 rotates and contracts under the action of the crank 13. At the same time, the movable block 14 can pull the moving frame 11 to move horizontally towards the end close to the T-shaped block 4 under the action of the crank 13, enabling the moving frame 11 to drive the cleaning plate 12 to move to the extreme position at one end of the T-shaped block 4 and fit with the T-shaped block 4. As the T-shaped block 4 moves back to the extreme position towards the direction away from the L-shaped rod 6, at this time, the touch display screen 5 and the inner wall of the rectangular frame 2 are in a horizontal state and contact the sponge block on the inner wall of the cleaning plate 12, and the rack 20 is disengaged from the toothed ring 21. Furthermore, the crank 13 rotates back towards the direction away from the T-shaped block 4 under the action of the first torsion spring 15, and the movable block 14 can pull the cleaning plate 12 to move horizontally back towards the direction away from the T-shaped block 4 through the moving frame 11, so that the sponge block on the cleaning plate 12 can comprehensively clean the dust and fingerprints on the surface of the touch display screen 5, ensuring the cleanliness of the surface of the touch display screen 5.

[0056] On both sides of the T-shaped block 4 near the bottom at symmetrical positions, moving rods 26 are fixedly connected. Both ends of the fixing rod 7 are penetrated by the moving rods 26 and are horizontally movably connected. One end of each of the two moving rods 26 away from the T-shaped block 4 is fixedly connected with a piston plate 27 for extracting and discharging the disinfectant solution inside the storage box 22.

[0057] During use, through the storage box 22 provided on the ultrasonic device body 1, and the storage box 22 is fixedly supported on the ultrasonic device body 1. First, the disinfectant solution is stored in the inner wall of the storage box 22. Through the cylindrical shell 23 provided on the fixing rod 7, the cylindrical shell 23 is fixedly supported on the fixing rod 7.

Through the one-way inlet valve 251 provided on the liquid inlet pipe 25 and the one-way outlet valve 241 provided on the liquid discharge pipe 24, along with the T-shaped block 4 moving horizontally towards the fixed rod 7, the moving rod 26 can drive the piston plate 27 to move axially towards the end away from the liquid inlet pipe 25. At this time, the internal air pressure at the end of the cylindrical housing 23 close to the liquid inlet pipe 25 is in a negative pressure state, the one-way inlet valve 251 is in an open state, and the one-way outlet valve 241 is in a closed state. Thus, the liquid inlet pipe 25 can quantitatively extract the disinfectant liquid inside the storage tank 22 to the inner wall of the cylindrical housing 23. Along with the T-shaped block 4 moving horizontally back to its original position away from the fixed rod 7, the moving rod 26 can pull the piston plate 27 to move back towards the end close to the liquid inlet pipe 25, and the internal air pressure at the end of the cylindrical housing 23 close to the liquid inlet pipe 25 is in a positive pressure state.

Furthermore, the liquid discharge pipe 24 can quantitatively discharge the disinfectant liquid inside the cylindrical housing 23 to the inner wall of the cleaning plate 12, and the disinfectant liquid wets the sponge block on the inner wall of the cleaning plate 12. When the cleaning plate 12 moves horizontally to comprehensively clean the dust and fingerprints on the surface of the touch display screen 5, the sponge block on the inner wall of the cleaning plate 12 can evenly wipe the disinfectant liquid on the surface of the touch display screen 5, achieving the disinfection of the surface of the touch display screen 5 and avoiding the problem that when medical staff manually touch the touch display screen 5 for operation, fingerprints and bacteria on the hands are easily left on the surface of the touch display screen 5, resulting in cross-infection caused by multiple people using it.
