Description

Technical Field

[0001] The utility model belongs to the technical field of elbow support equipment, in particular to an elbow support device for alleviating chronic injuries of ultrasound physicians. Background Art

[0002] Ultrasound physicians primarily use ultrasound machines to provide clinical doctors with a foundation for medical diagnosis. These examinations are closely integrated with obstetrics and gynecology, as well as examinations of internal organs like the heart and liver. Current examinations are still performed manually, requiring doctors to maintain a consistent posture for extended periods of time, with their elbows suspended in the air without support. This prolonged operation can easily lead to fatigue injuries, necessitating a device that can provide elbow support to alleviate the doctor's stress.

[0003] Existing ultrasound examination beds have no guardrails on the edges, mainly to facilitate patients getting in and out of bed. Therefore, the newly designed elbow support device for ultrasound examination must be able to support the doctor's elbow and allow the elbow to move along the bed without affecting the patient's getting in and out of bed. Utility Model Content

[0004] In view of the above situation, in order not to affect the patient's getting on and off the examination bed and to ensure effective support for the doctor's elbow, it is also necessary to facilitate the doctor to move the elbow position along the edge of the bed according to the examination needs. The utility model provides an elbow support device to reduce chronic injuries of ultrasound physicians. The elbow support device is fixed on the edge of the bed through a snap-fit ​​structure, and the device can slide horizontally along the edge of the bed and is easy to disassemble from the edge of the bed. The elbow support device can be installed on the bed as needed, which not only ensures the support effect for the doctor's elbow, but also does not affect the patient's getting on and off the bed.

[0005] The technical solution adopted by the present invention is as follows: The present invention provides an elbow support device for alleviating chronic injuries of ultrasound physicians, comprising a hospital bed, wherein a sliding adaptive interlocking fixing device is provided on the side wall of the hospital bed, and a support structure for relieving elbow fatigue for placing the arm is provided on the adaptive interlocking fixing device; the adaptive interlocking fixing device comprises a fixed edge limiting structure, a side pushing structure, a vertical direction feedback device and an opposite side feedback fixing device, the fixed edge limiting structure is engaged and slid along the edge of the hospital bed, the side pushing structure is engaged and slidably arranged in the fixed edge limiting structure, the vertical direction feedback device is in contact with and connected to the fixed edge limiting structure, and the opposite side feedback fixing device is engaged and slidably arranged on the vertical direction feedback device, fixing the device to the edge of the hospital bed from four directions, thereby achieving the effect that the device slides along the hospital bed and will not fall off.

[0006] Furthermore, the fixed-side limiting structure includes a three-side positioning plate, a three-side adjustment plate, a transverse partition, a partition slide, an internal fixed rack, and an offset engaging rack. The three-side positioning plate is in contact with the bed, the three-side adjustment plate engages and slides along the outer wall of the three-side positioning plate, the transverse partition is fixedly installed on the inner wall of the three-side adjustment plate, the partition slide is fixedly set on the outer wall of the three-side positioning plate, the transverse partition slides horizontally along the partition slide, the internal fixed rack is fixedly installed on the bottom wall of the transverse partition, and the offset engaging rack engages and slides in the partition slide.

[0007] Furthermore, there is a spring connection between the transverse partition and the partition slide, and a spring connection between the offset locking rack and the bottom wall of the partition slide, and the offset locking rack slides vertically in the partition slide, and a handle is provided on the side wall of the offset locking rack, which can be displaced by pulling the handle, and the internal fixed rack is in contact with and connected to the offset locking rack. When the internal fixed rack slides outward along the partition slide, the offset locking rack will only give the internal fixed rack a small resistance. When the internal fixed rack slides into the interior of the partition slide, the side wall of the offset locking rack directly collides with the internal fixed rack, making the internal fixed rack unable to displace.

[0008] Furthermore, the side pushing structure includes a side sliding plate, a side horizontal push rod and a side push rod slot. The side push rod slot is fixedly arranged on the side wall of the three-side positioning plate. The side horizontal push rod slides horizontally along the side push rod slot. The side sliding plate is fixedly installed on the side horizontal push rod, and a spring is provided between the side sliding plate and the three-side positioning plate. A small ball is provided on the side wall of the side sliding plate to reduce the resistance of the side sliding plate when sliding along the edge of the bed.

[0009] Furthermore, the vertical direction feedback device includes a vertical sliding column, a vertical direction plate, a vertical column slide groove and a vertical adjustment guide rail. The vertical column slide groove is fixedly set on the upper wall of the fixed edge limiting structure, the vertical sliding column slides along the vertical column slide groove, the vertical direction plate is fixedly installed on the bottom wall of the vertical sliding column, the vertical adjustment guide rail is fixedly set on the inner wall of the three-side adjustment plate, the vertical direction plate and the three-side positioning plate are connected by a spring, and a small ball that engages and rotates is provided on the bottom wall of the vertical direction plate.

[0010] Preferably, an inclined slot is provided inside the vertical adjustment rail. When the top wall of the vertical sliding column slides along the slot in the vertical adjustment rail, the vertical sliding column will slide in the vertical direction due to the change in the shape of the slot in the vertical adjustment rail.

[0011] Furthermore, the edge feedback fixing device includes a connecting plate, a horizontal slide groove, a horizontal clamping plate, a hinge plate and an edge limiting column. The connecting plate is fixedly installed on the side wall of the vertical sliding column, and the connecting plate will slide downward with the movement of the vertical sliding column. The horizontal slide groove is fixedly set in the connecting plate, and the horizontal clamping plate slides in the horizontal direction along the horizontal slide groove, and the horizontal slide groove and the horizontal clamping plate are connected by a spring. The hinge plate is clamped and rotatably set on the horizontal clamping plate, and the edge limiting column is fixedly set on the hinge plate, and after the edge limiting column contacts the edge of the bed, it can slide with the edge of the bed.

[0012] Furthermore, a straight groove is provided on the side of the horizontal locking plate, a cross groove is provided on the side of the hinged plate, and a straight-shaped card strip for locking and sliding is provided in the horizontal locking plate. After the straight-shaped card strip is inserted into the horizontal locking plate from the straight-shaped groove, the angle of the cross groove in the hinged plate determines whether the hinged plate and the horizontal locking plate are horizontal or perpendicular to each other.

[0013] Furthermore, the support structure for relieving elbow fatigue includes a cylindrical sleeve, an inclined bracket, an arm support bracket, a sleeve and an elbow support plate. The cylindrical sleeve is fixedly mounted on the upper wall of the three-sided positioning plate through the bracket, and the inclined bracket is engaged and rotatable in the cylindrical sleeve. The arm support bracket and the inclined bracket are engaged and rotated through the bracket, and the inclined bracket and the arm support bracket are respectively interference fit with the bracket. Only when both arms are pressed can there be enough force to change the angle between the inclined bracket and the arm support bracket. The sleeve is hinged to the arm support bracket, and the elbow support plate is engaged and rotatable on the sleeve.

[0014] Preferably, the elbow support plate is configured as a long curved panel structure with a downward depression in the middle and convexities on all sides.

[0015] This solution provides an elbow support device that reduces chronic injuries to ultrasound physicians, and its beneficial effects are as follows:

[0016] (1) The internal fixed rack and the offset engaging rack on the three-side adjustment plate are in contact with each other so that when the three-side adjustment plate moves outward from the partition plate slot, the internal fixed rack can slide horizontally. However, when the three-side adjustment plate moves into the partition plate slot, the right-angled sides of the convex teeth on the internal fixed rack and the right-angled sides of the convex teeth on the offset engaging rack directly collide with each other, thereby preventing the three-side adjustment plate from continuing to move into the partition plate slot, thereby achieving relative fixation of the three-side positioning plate and the three-side adjustment plate;

[0017] (2) The inclined slot structure in the vertical adjustment guide rail can press the vertical sliding column downward when the three-side adjustment plate moves outward, so that the vertical flat plate contacts the upper and lower walls of the bed edge, achieving a fixing effect;

[0018] (3) After the horizontal clamping plate is inserted into the horizontal clamping plate through the straight slot, the hinged plate and the horizontal clamping plate are fixed to be horizontal or perpendicular to each other according to the position of the cross slot in the hinged plate;

[0019] (4) The tilt bracket and the arm support bracket are connected by snap-fitting rotation, which makes it easier to adjust the height of the elbow support. At the same time, the elbow support with a long curved panel structure can support the elbow without reducing the operating range of the ultrasonic testing equipment, and will not cause discomfort to the tester during the test.
