Description

Technical Field

[0001] This invention specifically relates to an arm support for ultrasound examination. Background Technology

[0002] Ultrasound examination can observe the position of the heart, measure the size of each ventricle, assess the function of the heart and the flow of blood in the heart chambers, clearly show the pleural effusion and assess the amount of effusion, and also show the growth and development of the fetus at each stage, accurately detect whether there are any abnormalities in the fetus, and is widely used in various departments.

[0003] During ultrasound examinations, the examiner's arm holding the probe needs to be suspended high for extended periods, which can easily lead to muscle strain in the neck, shoulders, lower back, and arms, making it difficult to perform examinations for long periods. Therefore, an arm rest is used for assistance during ultrasound examinations.

[0004] For example, Chinese invention patent number 201610216714.5 provides an ultrasound scanning arm support device. The rotation of a motor drives a lead screw to rotate, thereby changing the height of the movable block. A pulley sliding in a second groove on a crossbar can change the lateral position of the arm, and a support plate sliding in a third groove via a third slider can change the longitudinal position of the arm, thus reducing fatigue in the doctor's arm. However, traditional ultrasound examination arm supports are inconvenient to adjust quickly according to the examination position. During the examination, the support position needs to be gradually adjusted according to the examination position and height, resulting in inconvenience in use. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention proposes an ultrasound examination arm support to solve the technical problem mentioned in the background art: traditional ultrasound examination arm supports are inconvenient to use because they cannot be quickly adjusted according to the examination position, and the support position needs to be gradually adjusted according to the examination position and height during the examination, which leads to inconvenience in use.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an arm support for ultrasound examination, comprising:

[0007] A base, on which a support column is fixedly mounted;

[0008] The mounting sleeve is slidably fitted onto the support column along the axis of the support column, and a fixing frame is provided on the mounting sleeve;

[0009] A sliding frame is slidably fitted onto the fixed frame along the axis of the fixed frame, and one end of the sliding frame is provided with a hinged support.

[0010] A movable rod is slidably disposed within the fixed frame along the axis of the fixed frame. A first braking assembly and a second braking assembly are respectively provided at both ends of the movable rod. During sliding, the movable rod simultaneously fixes or releases the position of the mounting sleeve and the sliding frame through the first and second braking assemblies.

[0011] A first locking component is provided on the movable rod to fix the position of the movable rod after it has slid.

[0012] In a preferred embodiment, the first braking component includes:

[0013] The brake frame has a through groove on the mounting sleeve that extends along the axis of the fixed frame, and the brake frame is slidably engaged in the through groove.

[0014] A locking block is disposed on one side of the brake frame. The support column has a sliding groove extending along its axis and multiple sets of fixed grooves spaced apart along its axis. One end of the movable rod passes through the sliding groove and is connected to the brake frame. The locking block is engaged in one of the sets of fixed grooves.

[0015] In a preferred embodiment, a first elastic element is provided between the base and the mounting sleeve.

[0016] In a preferred embodiment, the second braking component includes:

[0017] The fixed pin has a through mounting groove on the fixed frame and multiple sets of limiting grooves spaced apart along its axis on the sliding frame. The fixed pin is slidably engaged in the mounting groove and engaged in one of the limiting grooves.

[0018] The connecting rod is hinged at one end to the hinge seat on the movable rod and at the other end to the fixed pin;

[0019] The second elastic element is disposed at one end of the movable rod and contacts the inner side of the fixed frame.

[0020] In a preferred embodiment, a shielding cylinder is provided on the base, and a limiting frame extending along its axis is provided on one side of the shielding cylinder. The fixing frame is slidably engaged in the limiting frame along the extending direction of the limiting frame.

[0021] In a preferred embodiment, the first locking assembly includes a locking block disposed on the movable rod, and a locking groove is provided on the fixed frame. The locking block is slidably engaged in the locking groove along the axial direction of the movable rod, and the locking block can be interference-fitted with one end of the locking groove.

[0022] In a preferred embodiment, the support is provided with an anti-pressure sore pad, which is made of gel material.

[0023] In a preferred embodiment, a mounting rod is slidably passed through the bottom of the support bracket along its axis, a mounting block is provided at one end of the mounting rod, a hinged connecting arm is provided on the mounting block, and a fixing sleeve for mounting an ultrasonic probe is provided at one end of the connecting arm.

[0024] In a preferred embodiment, one end of the connecting arm is connected to the mounting block via a second locking assembly. The connecting arm can be rotated along the hinge point between its one end and the mounting block, and then its position can be fixed or released via the second locking assembly.

[0025] In a preferred embodiment, the second locking component includes:

[0026] A mounting frame is provided at one end of the connecting arm and is fixedly connected to the fixing sleeve;

[0027] A locking rod, one end of which is slidably engaged on the mounting frame, and is provided with a button, which passes through the mounting frame and extends outward;

[0028] A third elastic element is disposed between the button and the mounting frame;

[0029] A connecting sleeve is provided at the other end of the connecting arm and is rotatably inserted into a mounting hole opened on the mounting block. One end of the mounting hole is provided with multiple sets of circumferentially distributed toothed grooves.

[0030] A fixing tooth is provided at the other end of the locking rod and is slidably engaged on the connecting sleeve along the axial direction of the connecting sleeve and extends outward. The fixing tooth is engaged in the tooth groove.

[0031] Compared with the prior art, the present invention has the following beneficial effects:

[0032] 1. In use, this arm support first controls the movement of the movable rod via the first locking component, thereby releasing the first and second braking components from fixing the position of the mounting sleeve and the sliding frame. Medical personnel place their arm on the support and move it to a suitable position, causing the mounting sleeve to slide on the support column and simultaneously causing the sliding frame to slide on the fixed frame. This facilitates quick and easy movement of the ultrasound probe to the position to be examined. Then, the first locking component controls the movement of the movable rod and fixes its position after sliding, thus fixing the mounting sleeve on the mounting column and simultaneously fixing the sliding frame on the fixed frame. This quickly fixes the position of the support. During the examination, there is no need to gradually adjust the support position according to the examination location and height to support the medical personnel's arm, reducing the labor intensity of the medical personnel's arms during ultrasound examinations, preventing the arms from being suspended for extended periods and causing soreness, and improving the efficiency of ultrasound examinations.

[0033] 2. During use, the ultrasound probe can be manipulated by holding the mounting frame to perform ultrasound examinations on patients. When operating the ultrasound probe, pressing the button causes the locking rod to slide laterally on the mounting frame, disengaging the fixing teeth from the tooth grooves. This releases the connection between the connecting sleeve and the mounting block, allowing the ultrasound probe to move slightly. Simultaneously, the ultrasound probe can slide along the mounting rod axis and the support bracket can rotate along the hinge point between the support bracket and the sliding frame, thus moving the ultrasound probe to examine the patient. When it is necessary to fix the ultrasound probe in place for an extended period, releasing the button allows the locking rod to slide back to its original position under the action of the third elastic element, locking the fixing teeth in the tooth grooves and completing the fixation of the ultrasound probe. This eliminates the need to hold the ultrasound probe for extended periods, further reducing the workload of medical staff. Attached Figure Description

[0051] The embodiments of the technical solution of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the technical solution of the present invention and are therefore intended to limit the scope of protection of the present invention.

[0052] Example:

[0053] like Figure 1 , 6As shown, the present invention provides an arm support for ultrasound examination, including a base 101, a support column 104 fixedly disposed on the base 101, an mounting sleeve 203 slidably sleeved on the support column 104 along its axis, a fixing frame 201 disposed on the mounting sleeve 203, a sliding frame 401 slidably sleeved on the fixing frame 201 along its axis, and a hinged support 403 disposed at one end of the sliding frame 401.

[0054] In use, the base 101 can be installed on the side of the ultrasound examination table using bolts or other fasteners. The support bracket 403 supports the arm of the medical staff performing the ultrasound examination, and a gel-based anti-pressure sore pad 404 is also provided on the support bracket 403 to prevent discomfort or pressure sores caused by prolonged placement of the medical staff's arm on the support bracket 403. During use, the mounting sleeve 203 can slide on the support column 104 to adjust the height of the support bracket 403, and the sliding frame 401 can slide laterally to adjust the lateral position of the support bracket 403. The support bracket 403 can also swing along its hinge point at one end of the sliding frame 401, facilitating the operation of the ultrasound probe 706.

[0055] like Figure 5 , 6 As shown in Figure 7, in this embodiment, a movable rod 301 that slides along its axis is provided inside the fixed frame 201. A first braking assembly and a second braking assembly are respectively provided at both ends of the movable rod 301. During the sliding process, the movable rod 301 fixes or releases the position of the mounting sleeve 203 on the support column 104 through the first braking assembly. The first braking assembly includes a brake frame 303. A through groove 204 is provided on the mounting sleeve 203 that runs through the axis of the fixed frame 201. The brake frame 303 is slidably locked in the through groove 204. A locking block 304 is provided on one side of the brake frame 303. A sliding groove 106 extending along its axis and multiple sets of fixed grooves 105 spaced apart along its axis are provided on the support column 104. One end of the movable rod 301 passes through the sliding groove 106 and is connected to the brake frame 303. The locking block 304 is locked in one of the fixed grooves 105.

[0056] In use, place your arm on the support bracket 403 and press down on your arm to move the support bracket 403 to the appropriate height. Then, control the movable rod 301 to slide along its axis within the fixed frame 201. During the movement of the movable rod 301, the brake bracket 303 slides within the through groove 204 until the locking block 304 engages with the fixed groove 105, thus fixing the height of the mounting sleeve 203 quickly. Furthermore, a first elastic element 107 is provided between the base 101 and the mounting sleeve 203, allowing the mounting sleeve 203 to quickly return to its original position after being released from fixation, facilitating use by different people and making the operation of the arm bracket more convenient.

[0057] like Figure 2 , 8 As shown, in this embodiment, during the sliding process, the movable rod 301 fixes or releases the position of the sliding frame 401 on the fixed frame 201 through the second braking assembly. The second braking assembly includes a fixing pin 307. The fixed frame 201 has a through mounting groove 205. The sliding frame 401 has multiple sets of limiting grooves 402 distributed at intervals along its axis. The fixing pin 307 is slidably locked in the mounting groove 205 and locked in one of the limiting grooves 402. One end of the connecting rod 306 is hinged to the hinge seat 305 on the movable rod 301, and the other end is hinged to the fixing pin 307. A second elastic member 308 is provided between one end of the movable rod 301 and the inner side of the fixed frame 201.

[0058] Before the movable rod 301 slides, the fixing pin 307 is not engaged in the limiting groove 402, allowing the support bracket 403 to move laterally by moving the arm, thus adjusting its lateral position. After adjustment, when the height of the mounting sleeve 203 is fixed by controlling the sliding of the movable rod 301 and under the action of the first braking component, one end of the movable rod 301 pushes the fixing pin 307 to engage in the limiting groove 402 via the connecting rod 306, thus fixing the relative position of the sliding frame 401 and the fixed frame 201. Therefore, the height and lateral position of the support bracket 403 can be adjusted simultaneously by operating the sliding of the movable rod 301, which is convenient and quick, eliminating the need for cumbersome operations and improving the efficiency of ultrasound examination. The second elastic element 308 can control the movable rod 301 to reset, facilitating the quick release of the first and second braking components after the movable rod 301 is released from its fixation.

[0059] like Figure 1 , 5 As shown, in this embodiment, a shielding cylinder 102 is provided on the base 101, and a limiting frame 103 extending along its axis is provided on one side of the shielding cylinder 102. The fixing frame 201 is slidably locked in the limiting frame 103 along the extending direction of the limiting frame 103. The shielding cylinder 102 shields the various parts on the support column 104.

[0060] like Figure 6 , 7As shown, the first locking assembly includes a locking block 302, which is disposed on the movable rod 301. A locking groove 202 is provided on the fixed frame 201. The locking block 302 is slidably engaged within the locking groove 202 along the axial direction of the movable rod 301, and the locking block 302 can be interference-fitted with one end of the locking groove 202. The position of the movable rod 301 can be adjusted by sliding the locking block 302 along the locking groove 202. After sliding the locking block 302 to one end of the locking groove 202 and fixing it with the interference fit, the position of the movable rod 301 is fixed.

[0061] like Figure 2 , 3 As shown in Figure 4, in this embodiment, a mounting rod 501 is slidably inserted through the bottom of the support bracket 403 along its axis. A mounting block 502 is provided at one end of the mounting rod 501, and a hinged connecting arm 601 is provided on the mounting block 502. A fixing sleeve 705 for mounting the ultrasonic probe 706 is provided at one end of the connecting arm 601. One end of the connecting arm 601 is connected to the mounting block 502 via a second locking assembly. The connecting arm 601 can rotate along the hinge point between its one end and the mounting block 502, and its position can be fixed or released by the second locking assembly.

[0062] The ultrasound probe 706 can be placed inside the fixed sleeve 705 for use, and the position of the ultrasound probe 706 can be adjusted by moving one end of the hand-held connecting arm 601, thereby expanding the range of ultrasound examination. The second locking assembly includes a mounting frame 603 at one end of the connecting arm 601, which is fixedly connected to the fixing sleeve 705. One end of the locking rod 701 is slidably engaged on the mounting frame 603 and has a button 702. The button 702 passes through the mounting frame 603 and extends outward. A third elastic element 704 is provided between the button 702 and the mounting frame 603. The other end of the connecting arm 601 has a connecting sleeve 602, which is rotatably engaged in the mounting hole 503 on the mounting block 502. One end of the mounting hole 503 has multiple sets of circumferentially distributed toothed grooves 504. The other end of the locking rod 701 has a fixing tooth 703, which is slidably engaged on the connecting sleeve 602 along the axial direction of the connecting sleeve 602 and extends outward. The fixing tooth 703 is engaged in the toothed groove 504.

[0063] During the operation of the ultrasound probe 706, pressing the button 702 can cause the locking rod 701 to slide laterally on the mounting frame 603, thereby disengaging the fixing tooth 703 from the tooth groove 504, thus releasing the fixing between the connecting sleeve 602 and the mounting block 502. This allows the ultrasound probe 706 to move slightly. Simultaneously, the ultrasound probe 706 can slide along the axis of the mounting rod 501 and the support support 403 can rotate along the hinge point between the support support 403 and the sliding frame 401, thereby moving the ultrasound probe 706 to examine the patient. When it is necessary to fix the position of the ultrasound probe 706 for a long time, the button 702 can be released. Under the action of the third elastic element 704, the locking rod 701 slides back to its original position, causing the fixing tooth 703 to lock into the tooth groove 504, thus fixing the position of the ultrasound probe 706. This eliminates the need to hold the ultrasound probe 706 for a long time, further reducing the workload of medical staff.

[0064] Specific usage and beneficial effects of the present invention:

[0065] When using this arm support, firstly, by laterally moving the locking block 302, one end of it disengages from the interference fit with the locking groove 202, controlling the movement of the movable rod 301. This releases the first and second braking components from fixing the mounting sleeve 203 and the sliding frame 401 to their positions. Medical personnel then place their arm on the support 403 and move it to a suitable position, causing the mounting sleeve 203 to slide on the support column 104. Simultaneously, this causes the sliding frame 401 to slide on the fixed frame 201, facilitating the quick and easy movement of the ultrasound probe 706 to the position to be tested. Then, by moving the locking block 302, one end is locked and fixed to one end of the locking groove 202, controlling the sliding of the movable rod 301. The sliding movable rod 301 is fixed in position, so that the locking block 304 is engaged in the fixing groove 105 to fix the position of the mounting sleeve 203 on the mounting column. At the same time, the fixing pin 307 in the second braking assembly is engaged in the limiting groove 402 to fix the position of the sliding frame 401 on the fixing frame 201. Thus, the position of the support 403 is quickly fixed. During the examination, there is no need to gradually adjust the support position according to the examination position and height to support the arms of medical staff, reducing the labor intensity of the arms of medical staff during ultrasound examination, avoiding the soreness caused by the arms being suspended for a long time, and improving the work efficiency of ultrasound examination.

[0066] The foregoing has shown and described the basic principles and main features of the present invention and its advantages. It will be apparent to those skilled in the art that the present invention is not limited to the details of the above exemplary embodiments.
