Description

TECHNICAL FIELD

[0001] The utility model belongs to the auxiliary medical instrument field, concretely relates to a hand arm support for assisting ultrasonic examination. BACKGROUND

[0002] Ultrasound examination is a medical imaging technology that uses the characteristics of high-frequency sound waves reflecting and absorbing in the human body to generate images. It is a safe, non-invasive, and non-radiation examination method, widely used in gynecology and obstetrics, cardiology, abdomen, ophthalmology, blood vessels, and musculoskeletal fields. Ultrasound examination can display the structure and function of organs in real time, providing dynamic and real-time diagnostic information for doctors. Although ultrasound examination has many advantages, in actual operation, doctors need to hold the probe for a long time and accurately aim at the examination area. This operation not only requires doctors to have high professional skills, but also may cause arm fatigue and repetitive strain injury. In addition, in order to obtain high-quality images, doctors must keep the probe stable, and any slight movement may affect the clarity of the image.

[0063] In order to make the above technical features and advantages or technical effects of the technical scheme of the present application more obvious and easy to understand, the following will be described in detail with reference to the drawings.

[0064] The embodiment specifically discloses a front structure diagram of an arm support for assisting ultrasonic examination, as shown in Figure 1 and Figure 2As shown, its main components include: bracket body 2, height fixing rod 3, first connector 4, second connector 5, first rod 6, rod connector 7, second rod 8, and gasket 9.

[0065] The aforementioned main components are fixed by a base 1, the structure of which is as follows: Figure 3 As shown, the system comprises a base body 11, a bayonet fixing button 12, and a clamp fixing button 13. The base 11 has a horizontal bayonet 14 and a vertical clamp 15. The bayonet fixing button 12 is threadedly connected to the horizontal bayonet 14. This base 1 is designed primarily for examination beds with bedside guardrails, therefore the horizontal bayonet 14 is mainly used. The clamp fixing button 13 is threadedly connected to the base body 11. By rotating the clamp fixing button 13, clamping and adjustment of the clamping thickness can be achieved. Inserting the cylindrical part 41 of the first connector 4 into the horizontal bayonet 14 and tightening the bayonet fixing button 12 establishes the connection between the base 1 and the first connector 4, preventing rotation of the first connector 4 and other components.

[0066] The structure of the main body 2 of the support is as follows Figure 4 As shown, the device includes two height adjustment sections 21 and 22 and a rod fixing section 23, which are integrated as a single unit and cannot be moved or disassembled relative to each other. Both the first height adjustment section 21 and the second height adjustment section 22 have a through-cubic cubic space 24 (length × width: 20mm × 20mm) for inserting the first connector 4 and the second connector 5, respectively. Each of the two height adjustment sections has three square holes 25 (5mm on each side) on the front and back for inserting the height fixing rod 3. The rod fixing section 23 is U-shaped, with round holes 26 (3.5mm in diameter) on both the top and bottom surfaces. The first rod 6 is inserted into the U-shaped notch and fixed to the bracket body 2 with screws.

[0067] The structure of the height fixing rod 3 is as follows Figure 5 As shown, the bracket body 2 consists of a round rod 31 (5mm in diameter) and two square rods 32 (4.8mm x 4.8mm). These three parts form a single unit and cannot be moved or disassembled. In use, the two square rods 32 are inserted into the square holes 25 of the two height adjustment sections of the bracket body 2, with their lower surfaces contacting the upper surfaces of the first connector 4 and the second connector 5, thus fixing the height of the bracket body 2. By inserting the height-fixing rods 3 into the square holes 25 of different heights on the bracket body 2, the height of the bracket body 2 can be adjusted to suit different application scenarios.

[0068] The structure of the first connector 4 is as follows: Figure 6As shown in the figure, it is composed of a cylinder 41 (diameter 12 mm, height 30 mm) and a cube 42 (length × width × height: 19.9 mm × 19.9 mm × 40 mm). The two are integrated and cannot move relative to each other or be disassembled. The cylinder 41 of the first connector 4 is inserted into the horizontal bayonet 14 of the base 1, and the cube 42 is inserted into the first height adjustment part 21 of the bracket body 2 to play a connecting role.

[0069] The structure of the second connector 5 is as Figure 7 shown, which is a cube (length × width × height: 19.9 mm × 19.9 mm × 48 mm). It directly contacts the base 1 at the bottom and is inserted into the second height adjustment part 22 of the bracket body 2 at the top, playing a role in supporting the bracket body 2 and reducing the shear force on the first connector 4.

[0070] The structure of the first rod 6 is as Figure 8 shown, which is composed of a cuboid rod 61 and cylinders 62 at both ends. Circular holes 63 (diameter 3.5 mm) are respectively provided in the centers of the two cylinders 62. The proximal end of the first rod 6 is connected to the bracket body 2, and the distal end is connected to the rod connector 7, both connected by mother-son screws.

[0071] The structure of the rod connector 7 is as Figure 9 shown, in the shape of a "worker" character, with circular holes 71 provided at both ends, which are respectively connected to the first rod 6 and the second rod 8, both connected by mother-son screws.

[0072] The structure of the second rod 8 is as Figure 10 shown, which is composed of a cuboid rod 81 and cylinders 82 at both ends. Circular holes 83 (diameter 3.5 mm) are respectively provided in the centers of the two cylinders 82. The proximal end of the second rod 8 is connected to the rod connector 7, and the distal end is connected to the gasket 9, both connected by mother-son screws.

[0073] The structure of the gasket 9 is as Figure 11 shown, which is an arc-shaped piece with a circular hole 91 (diameter 3.5 mm) in the center, and is connected to the distal end of the second rod 8 by a mother-son screw. The gasket 9 directly supports the arm, and a layer of sponge is attached to the surface to play a buffering role.

[0074] Specification of mother-son screws: 3 sets of mother-son screws with a diameter of 3 mm and a length of 50 mm; 1 set of mother-son screws with a diameter of 3 mm and a length of 30 mm.

[0075] Instructions for using this arm bracket:

[0076] In use, the base 1 is fixed on the bedside guardrail, and the height is adjusted by the height fixing rod 3. After the height is fixed, the support body 2 and the first rod 6, the first rod 6 and the rod connector 7, and the rod connector 7 and the second rod 8 can be freely rotated, so that the end gasket 9 can freely move in the horizontal direction. When performing B-ultrasound examination, the examiner can place the arm on the gasket 9, thereby achieving the purpose of reducing fatigue and increasing stability on the basis of ensuring the flexibility of the arm.

[0077] Although the utility model has disclosed as above with the embodiment, it is not used to limit the utility model, the ordinary skilled person in the art to the technical scheme of the utility model carries out the proper modification or equivalent replacement, should be covered in the protection scope of the utility model, the protection scope of the utility model is limited by claim.
