Description

Technical Field

[0001] The present invention relates to the technical field of lung injury diagnosis, and in particular to an ultrasonic diagnostic instrument. Background Art

[0002] Ultrasound diagnostics is a common medical diagnostic tool, serving a variety of roles in diagnosing conditions. Chest CT is the gold standard for diagnosing lung injury, but performing chest CT scans outside the home for critically ill trauma patients carries significant risks and poses challenges in dynamic observation. Bedside chest radiographs have low sensitivity and specificity for diagnosing lung disease. Traditional imaging tools are increasingly inadequate for assessing respiratory function in critically ill patients, limiting the early diagnosis of hospital-acquired lung injury in these patients.

[0003] To address this issue, current research is using ultrasound to collect lung tissue images from critically ill trauma patients. Ultrasound scans different locations within the lung tissue to detect changes in ventilation and water content (ventilation-blood flow). Lung imaging images are analyzed using normal and abnormal M-mode sampling. Predictive models identify increased lung water and hypoventilation, which are then combined with dynamic changes in the oxygenation index from blood gas analysis. Statistical analysis is then used to determine the sensitivity and specificity of this new method for diagnosing lung injury in critically ill trauma patients.

[0004] Ultrasound diagnostic equipment, a crucial component of diagnostic testing, requires multiple use on patients. To carefully determine whether the captured images meet requirements, the ultrasound system's bracket must be rotated during the acquisition process to adjust the display screen position. Current ultrasound system display brackets are typically restrained by friction, which can easily cause them to rotate, affecting smooth image acquisition. Summary of the Invention

[0042] The following embodiments of the technical solution of the present invention will be described in detail with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention and are therefore only examples and are not intended to limit the scope of protection of the present invention.

[0043] Please also refer to Figures 1-6 This embodiment provides an ultrasonic diagnostic instrument, including a diagnostic instrument body 1, a fixed bracket 2, a rotating shaft 3, a rotating bracket 4, a display screen 5 and a clamping mechanism 6.

[0044] A fixed bracket 2 is mounted on the diagnostic instrument body 1, a rotating shaft 3 is rotatably mounted on the end of the fixed bracket 2 away from the diagnostic instrument body 1, a rotating bracket 4 is fixedly mounted on the rotating shaft 3, and a display screen 5 is mounted on the rotating bracket 4. It should be understood that the diagnostic instrument body 1 includes all parts other than the screen of a typical ultrasonic diagnostic instrument, and the display screen mounted on the rotating bracket 4 can still display the image output by the diagnostic instrument body 1. The rotating shaft 3 is rotatably connected to the fixed bracket 2.

[0045] The clamping mechanism 6 is mounted on the fixed bracket 2 and is capable of clamping the rotating shaft 3. The clamping mechanism 6 can be rotated and pushed toward the rotating shaft 3 to release the clamping mechanism and rotate the rotating shaft 3. It should be understood that before the clamping mechanism 6 is pushed and rotated, it clamps the rotating shaft 3, restricting its movement. After the rotating shaft 3 is rotated to the desired position, the clamping mechanism 6 can be released and re-clamped.

[0046] In other embodiments, the clamping mechanism 6 includes a fixed component 61, a gear ring 62, a driving component 63, a driven component 64 and a clamping member 65; the fixed component 61 is provided on the fixed bracket 2, and the gear ring 62 is rotatably provided at the end of the fixed component 61 away from the fixed bracket 2; a slot 31 is provided at the end of the rotating shaft 3 close to the fixed component 61, and the driving component 63 is slidably provided on the gear ring 62 and the fixed component 61, and the driving component 63 is connected to the gear ring 62 through a spline. Component 63 can be inserted into slot 31 and drive the rotating shaft 3 to rotate. Two sets of driven components 64 are provided and are oppositely arranged on both sides of the gear ring 62. The driven components 64 are slidably mounted on the fixed component 61. The rotation of the gear ring 62 causes the two driven components 64 to slide in opposite directions, pushing the clamping component 65. The clamping component 65 is slidably mounted on the fixed component 61 and can automatically clamp the rotating shaft 3. The pushing of the driven components 64 can release the clamping component 65. It should be understood that when the clamping mechanism 6 is not operated, the clamping component 65 automatically clamps the rotating shaft 3. Because the gear ring 62 and the drive assembly 63 are splined together, the sliding of the drive assembly 63 does not cause the gear ring 62 to move. Instead, the rotation of the drive assembly 63 causes the gear ring 62 to rotate synchronously. When the rotating shaft 3 needs to be rotated, the drive assembly 63 is rotated and pushed toward the rotating shaft 3. The rotation of the drive assembly 63 causes the driven assembly 64 to slide via the gear ring 62. Just before the drive assembly 63 is inserted into the slot 31, the driven assembly 64 pushes the clamping member 65 to release the clamping member 65 from the rotating shaft 3. The drive assembly 63 is then pushed to insert the drive assembly into the slot 31, and then rotated to rotate the rotating shaft 3. After the drive assembly 63 is rotated to the desired position, the rotating shaft 3 is released, the components of the clamping mechanism 6 are reset, and the clamping member 65 retains the rotating shaft 3 in its new position. It should be noted that the drive assembly 63 always rotates in the same direction. It should also be understood that the drive assembly 63 can rotate and slide within the fixed assembly 61, but cannot cause the fixed assembly 61 to rotate or slide.

[0047] In other embodiments, the fixing assembly 61 includes a fixing rod 611 and a fixing block 612. The fixing rod 611 is mounted on the fixing bracket 2, and the fixing block 612 is mounted on the fixing rod 611. The end surface of the fixing block 612 near the rotating shaft 3 is provided with an axial sliding hole 6121. The driving assembly 63 is slidably disposed within the sliding hole 6121. The gear ring 62 is rotatably mounted on the end of the fixing block 612 away from the rotating shaft 3 and is coaxial with the sliding hole 6121. It should be understood that the sliding hole 6121 is coaxial with the slot 31. The fixing rod 611 is an L-shaped rod.

[0048] In other embodiments, the drive assembly 63 includes a drive rod 631 and a chuck 632. The drive rod 631 is slidably inserted into the gear ring 62 and the slide hole 6121 and is spline-connected to the gear ring 62. The chuck 632 is located on the drive rod 631 at one end near the rotating shaft 3. The chuck 632 can be inserted into the slot 31 and can drive the rotating shaft 3 to rotate. It should be understood that the chuck 632 is a polygonal cylinder, and the slot 31 has the same shape and size as the chuck 632.

[0049] In other embodiments, the driven assembly 64 includes a driven connecting rod 641, a driven rack 642, a wedge 643, and a return spring 644. The driven connecting rod 641 is mounted on the fixed block 612, and the driven rack 642 is slidably connected to the driven connecting rod 641 and meshes with the gear ring 62. The wedge 643 is mounted on the driven rack 642 and connected to the driven connecting rod 641 via the return spring 644. The wedge 643 can push the clamping member 65. It should be understood that the rotation of the gear ring 62 causes one driven rack 642 to slide toward the clamping member 65 and the other driven rack 642 to slide away from the clamping member 65. Before the clamping head 632 is about to be inserted into the clamping slot 31, the wedge 643 pushes the clamping member 65 away from the rotating shaft 3.

[0050] In other schemes, the clamping component 65 includes a base plate assembly 651, a pushing assembly 652 and a clamping assembly 653; the base plate assembly 651 is arranged on the fixed block 612, the pushing assembly 652 is slidably arranged on the base plate assembly 651, and the clamping assembly 653 is provided with two groups, and is relatively arranged on both sides of the pushing assembly 652; the pushing assembly 652 can spontaneously make the two clamping assemblies 653 clamp the rotating shaft 3, and the wedge block 643 can push the pushing assembly 652 to slide toward the rotating shaft 3, so that the two clamping assemblies 653 are away from the rotating shaft 3.

[0051] In other embodiments, the base plate assembly 651 includes a base plate connecting rod 6511 and a base plate body 6512; the base plate connecting rod 6511 is arranged on the fixed block 612, the base plate body 6512 is arranged on the base plate connecting rod 6511, the pushing assembly 652 is slidably arranged on the base plate body 6512, and the clamping assembly 653 is rotatably arranged on the base plate body 6512.

[0052] In other embodiments, the pushing assembly 652 includes a double-sided rack 6521, a rack link 6522, and a clamping spring 6523. The double-sided rack 6521 is slidably mounted on the base plate body 6512. The wedge block 643 pushes the double-sided rack 6521 to slide, moving the two clamping assemblies 653 away from the rotating shaft 3. A sliding groove 6513 is provided on the base plate body 6512 near the rotating shaft 3. One end of the rack link 6522 is connected to the double-sided rack 6521, and the other end extends toward the fixed block 612 and is slidable within the sliding groove 6513. The clamping spring 6523 is connected to the rack link 6522 at one end and to the base plate link 6511 at the other end. The clamping spring 6523 drives the rack link 6522 to abut the bottom surface of the sliding groove 6513. It should be understood that the clamping spring 6523 is in a stretched state before any human intervention.

[0053] In other embodiments, the clamping assembly 653 includes a gear 6531, a clamping link 6532 and a clamping plate 6533; the gear 6531 is rotatably disposed on the base plate body 6512 and engages with the double-sided rack 6521; one end of the clamping link 6532 is connected to the gear 6531, and the other end is connected to the clamping plate 6533, and the clamping plate 6533 squeezes the rotating shaft 3 under the drive of the clamping spring 6523.

[0054] The use process of the above-mentioned ultrasonic diagnostic instrument is as follows:

[0055] Rotate and push the driving rod 631 in the desired rotation direction, so that the gear ring 62 rotates, one driven rack 642 slides toward the double-sided rack 6521, and the other driven rack 642 slides away from the double-sided rack; when the chuck 632 is about to be inserted into the slot 31, the wedge block 643 sliding toward the double-sided rack 6521 pushes the double-sided rack 6521 to slide toward the rotating shaft 3, and the double-sided rack 6521 simultaneously rotates the gear 6531, and the rotation of the gear 6531 drives the clamping plate 6533 away from the rotating shaft 3; then continue to push the chuck 632 to insert it into the slot 31, and the rotating shaft 3 can be rotated by rotating the chuck 632. When it is rotated to the desired position, the clamping head 632 is pulled out of the clamping slot 31 and the hand is released. The reset spring 644 drives the wedge block 643 and the driven rack 642 to reset, and the clamping spring 6523 drives the double-sided rack 6521 to reset, so that the gear 6531 rotates and the clamping plate 6533 clamps the rotating shaft 3 again.

[0056] The ultrasonic diagnostic apparatus can automatically clamp the rotating shaft to restrict its rotation when not in operation.
