Description

Technical Field

[0001] The utility model belongs to the field of brackets, and in particular relates to a wearable forearm auxiliary bracket. Background Art

[0002] The forearm auxiliary support is used in vitrectomy and cataract phacoemulsification. Eye surgery often requires the doctor to keep the forearm bent for a long time during the operation. The forearm will be suspended in the air for a long time, causing discomfort, which requires the assistance of the forearm support.

[0003] A Chinese patent with publication number CN209644940U discloses a mobile forearm stand for ultrasound imaging, which includes a forearm support assembly and a support assembly. The human body contact part of the forearm support assembly is made of memory foam with a U-shaped concave surface and is wrapped with a leather layer on the outside. The lower part of the support assembly is equipped with a universal caster with a brake. The column tube and the column rod can be easily adjusted in height through a mechanism. The forearm support assembly and the support assembly are fixed with a fixing cap after being adjusted to a suitable angle. The forearm support provided above allows inspectors to comfortably operate ultrasound diagnostic equipment and reduce the labor intensity of inspectors. The support is also flexible and convenient to move and has low noise.

[0004] However, the forearm bracket is supported by a column tube and a column rod. When the inspector needs to adjust the position during the inspection, the forearm bracket needs to be pushed to move at the same time. The operation steps are cumbersome, and the forearm bracket is large in size, which occupies too much medical space resources, making the medical space more crowded.

[0005] In view of this, the present utility model is proposed. Utility Model Content

DETAILED DESCRIPTION

[0025] The utility model will now be further described in detail with reference to the accompanying drawings.

[0026] See also Figure 1-5 As shown, in this embodiment, a wearable forearm auxiliary support is provided, including: a strap 1, two mounting blocks 3 are installed on the lower side of the strap 1, a waist belt 2 is installed on the lower side of the two mounting blocks 3, and a forearm support seat 4 is installed on one side of the two mounting blocks 3, wherein the strap 1 has the same structural principle as the strap disclosed in the comparative document CN205162001U, and the waist belt 2 has the same structural principle as the waist belt in the prior art;

[0027] The two mounting blocks 3 are rotatably matched with a rotating rod 7 fixedly connected to the two forearm support pads 4, and a gear 9 is installed on the circumference of the rotating rod 7. One side of the two mounting blocks 3 is slidably matched with an extrusion rod 6, and one side of the extrusion rod 6 is equipped with a stopper 10 that is mutually engaged with the gear 9. An inner cavity 8 is provided in the two mounting blocks 3, and a clamping piece 11 is installed between the stopper 10 and the inner cavity 8. An elastic telescopic rod 18 corresponding to the clamping piece 11 is installed on one side of the stopper 10.

[0028] One aspect of the application of this embodiment is: when it is necessary to support the elbow, the inspector first wears the brace 1 and the belt 2, and then places the elbow on the upper side of the forearm support seat 4. After the inspector adjusts the forearm support seat 4 to a suitable angle with the elbow, the inspector uses the upper arm to squeeze the squeezing rod 6. The movement of the squeezing rod 6 drives the movement of the block 10. The movement of the block 10 clamps and fixes the gear 9. When the block 10 clamps and fixes the gear 9, the block 10 and the clamping piece 11 are clamped and fixed. The gear 9 is fixed to the forearm support seat 4 through the rotating rod 7, thereby completing the support of the inspector's elbow.

[0029] By means of the provided shoulder strap 1 and waist belt 2, the inspector can fix the forearm support seat 4 to the upper body through the shoulder strap 1 and waist belt 2, so that the inspector can adjust the position during the inspection and drive the forearm support seat 4 to move at the same time, thereby reducing the medical space resources occupied by the forearm support, thereby improving the flexibility of the forearm support seat 4. By means of the provided stop block 10, the inspector can place the elbow on the forearm support seat 4 to adjust the angle, and then use the upper arm to squeeze the squeezing rod 6 to engage the gear 9 through the stop block 10 to fix the forearm support seat 4, thereby facilitating the angle adjustment of the forearm support seat 4.

[0030] The clamping member 11 of this embodiment includes a clamping seat 15 installed on one side of the elastic telescopic rod 18 and the inner wall of the inner cavity 8, a clamping groove 16 is provided on the periphery of the clamping seat 15, a sliding ring 17 is slidably matched on the periphery of the clamping groove 16, and a buckle 12 that is mutually engaged with the clamping groove 16 is installed on one side of the stopper 10; the buckle 12 includes an elastic rod 13, a clamping block 14 installed on one side of the end of the elastic rod 13, and a chamfer is provided on one side of the clamping block 14; the upper and lower sides of the sliding ring 17 are provided with inclined surfaces that match the clamping block 14.

[0031] The buckle 12 is provided to engage with the slot 16 to fix the stopper 10. The sliding ring 17 is provided to enable the buckle 12 to engage with the sliding ring 17 when the stopper 10 is squeezed downward. When the squeezing is released, the sliding ring 17 is driven to move upward, so that the buckle 12 is released from the engagement with the slot 16. The chamfer is provided on the block 14 to facilitate the engagement of the buckle 12 with the peripheral side of the sliding ring 17. The inclined surface is provided to reduce the wear of the buckle 12 on the sliding ring 17. When the sliding ring 17 slides to the top of the slot 16, the buckle 12 is made to slide out of the slot 16 through the inclined surface.

[0032] A groove 21 is formed at one end of the rotating rod 7 of the present embodiment, a rotating shaft 20 is installed in the groove 21, and a connecting block 19 fixedly connected to the forearm support seat 4 is installed on the circumference of the rotating shaft 20; an arcuate groove is formed on the upper side of the forearm support seat 4, and a rubber pad 5 is installed inside the arcuate groove.

[0033] By means of the provided rotating shaft 20, the inspector can use his elbow to drive the forearm support seat 4 to rotate outward and inward at one end of the rotating rod 7 through the rotating shaft 20 during the inspection process, so that the inspector can adjust the forearm support seat 4 for external rotation and internal rotation, thereby improving the flexibility of the bracket. By means of the provided rubber pad 5, the inspector's hand and forearm position can be made more comfortable.

[0034] The present invention is not limited to the above-mentioned implementation modes. Anyone should be aware of the structural changes made under the inspiration of the present invention. Any technical solution that is the same or similar to the present invention falls within the protection scope of the present invention. The technology, shape, and structure that are not described in detail in the present invention are all known technologies.
