Description

Technical Field

[0001] This utility model relates to the field of auxiliary pads technology, specifically to an auxiliary pad for comfortable positioning of patients undergoing ultrasound examinations. Background Technology

[0002] Arteriovenous fistula is a common pathological condition in vascular surgery, often used as a vascular access for hemodialysis patients. It is crucial for maintaining dialysis treatment. During ultrasound examination of arteriovenous fistula, the patient needs to maintain a specific position to fully expose the examination site, so that the doctor can accurately obtain ultrasound images of the arteriovenous fistula.

[0003] Traditional examination methods often rely solely on an examination bed and a few ordinary soft pillows to assist patients in positioning. However, ordinary soft pillows are difficult to adjust in height and provide positional support according to the specific location of the arteriovenous fistula and the special requirements of ultrasound examination, which affects the accuracy of diagnosis. In addition, different patients have different limb thicknesses, and different ultrasound examinations require different limbs, making it difficult to provide stable support and easily interfering with the smooth progress of the examination.

[0004] To address these issues, we propose a comfort-enhancing pad for ultrasound examination patients. Utility Model Content

[0005] The purpose of this invention is to provide a comfortable positioning aid for patients undergoing ultrasound examinations, in order to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a patient positioning aid for ultrasound examination, including a fixed sponge pad.

[0007] The top of the fixed sponge pad has a square groove, and a square slider is movably inserted in the square groove. The top of the square slider is fixed with a movable sponge pad. A reserved hole is opened through the surface of the square slider, and a threaded post is movably inserted in the reserved hole. A round rod is movably inserted at the top of the fixed sponge pad.

[0008] The fixed sponge pad and the movable sponge pad have an arc-shaped groove on one side, and the movable sponge pad has a circular groove at its top. A rubber rod is movably inserted into the circular groove, and a silicone pad is fixed to the top of the rubber rod. The top of the silicone pad has an arc-shaped groove.

[0009] Preferably, the curvature of the top of the movable sponge pad matches the curvature of the bottom of the silicone pad. The movable sponge pad and the silicone pad are movable, allowing them to be placed stably. This makes them suitable for patients of different ages and limb sizes, improving flexibility. The sponge material is soft, improving comfort, while the silicone material is harder than the sponge material, providing better support.

[0010] Preferably, the circular grooves are provided in two sets, and the two sets of circular grooves are symmetrically provided on the top of the movable sponge pad. The rubber material has good friction and can increase the stability during use.

[0011] Preferably, the rubber rods are symmetrically provided in two sets, and the two sets of rubber rods are adapted to the circular grooves, which facilitates adjustment according to usage needs and is suitable for patients with different limb thicknesses.

[0012] Preferably, two sets of circular rods are symmetrically arranged, and the top ends of the two sets of circular rods are fixedly connected to the bottom end of the movable sponge pad to reduce displacement during use, thereby contributing to the stability of arteriovenous fistula examination during ultrasound.

[0013] Preferably, one end of the threaded insert passes through one side of the fixed sponge pad and the reserved hole, and is movably inserted into the inner wall of the fixed sponge pad, so that the height of the pad can be adjusted for use in the detection of different ultrasonic parts.

[0014] Preferably, multiple sets of reserved holes are provided, and the multiple sets of reserved holes are vertically equidistantly distributed, which can limit and fix the pad.

[0015] This invention provides a comfort support pad for patients undergoing ultrasound examinations, which has the following beneficial effects:

[0016] By using a combination of fixed sponge pads, round rods, threaded posts, square sliders, and pre-drilled holes, the height of the auxiliary support can be adjusted. This allows for appropriate elevation or lowering of the limb, making the angle between the blood vessel and the ultrasound probe more favorable for the propagation and reflection of ultrasound waves. This positions the arteriovenous fistula at a suitable ultrasound detection angle, thus more clearly displaying the size and location of the fistula opening, as well as the branching of surrounding blood vessels, improving diagnostic accuracy. It also allows doctors to quickly and easily adjust the patient's position without spending a lot of time repositioning the patient or finding suitable supports, improving the efficiency of ultrasound examinations.

[0017] By using a combination of movable sponge pads, silicone pads, circular grooves, arc-shaped grooves, and rubber rods, the device can adapt to patients with limbs of varying sizes. This allows for better fixation of the limb, keeping it in a suitable examination position and reducing limb movement during the examination. This minimizes image artifacts caused by limb movement, thereby improving image quality and diagnostic accuracy. The device can also be adjusted according to the actual condition of the patient's limb, reducing situations where the limb is suspended or compressed, allowing the patient to maintain a natural and relaxed posture during the examination and improving comfort.

[0027] In the above embodiment, when in use, the whole unit is placed in a suitable position. When the height needs to be adjusted, the threaded post 9 is rotated counterclockwise to remove it. The distance between the movable sponge pad 2 and the fixed sponge pad 1 is moved up and down. As the movable sponge pad 2 moves, the circular rod 8 and the square slider 10 move up and down in the fixed sponge pad 1. After moving to a suitable position, the threaded post 9 is inserted into the fixed sponge pad 1 and the corresponding reserved hole 11. The threaded post 9 is rotated clockwise so that the threaded post 9 and the fixed sponge pad 1 are connected by threads. Finally, the use position of the fixed sponge pad 1 and the movable sponge pad 2 is fixed.

A silicone pad 3 is fixed at the top of the rubber rod 7, and an arc-shaped groove 6 is provided at the top of the silicone pad 3; the curvature of the top of the movable sponge pad 2 matches the curvature of the bottom of the silicone pad 3, and the movable sponge pad 2 and the silicone pad 3 are movably arranged; two sets of circular grooves 5 are provided, and the two sets of circular grooves 5 are symmetrically provided at the top of the movable sponge pad 2; two sets of rubber rods 7 are symmetrically provided, and the two sets of rubber rods 7 are adapted to the circular grooves 5.

[0030] In the above embodiment, the fixed sponge pad 1 and the movable sponge pad 2 are placed at the position where the patient needs support, so that the arc-shaped groove 4 contacts the patient's limb to support the limb. If it is necessary to elevate the patient's limb, the fixed sponge pad 1 and the movable sponge pad 2 can be placed under the patient's limb. If it is necessary to lower the elevation, the movable sponge pad 2 can be removed. Alternatively, depending on the different parts of the patient's limb, the pads can be placed at the top of the movable sponge pad 2 or in the arc-shaped groove 6 of the silicone pad 3. When the silicone pad 3 is needed, the two sets of rubber rods 7 are inserted into the circular grooves 5 respectively for fixation. The pads can be selected and used according to various usage needs.
