Abstract
Description

[0002] After breast cancer surgery, to prevent wound dehiscence and complications such as subcutaneous fluid accumulation and lymphedema caused by upper limb movement, a brace is usually used to fix and support the patient's upper limb in a proper position, reduce the burden on the patient, ensure blood circulation and lymphatic return of the affected limb, thereby accelerating wound healing and recovery of upper limb function.
[0003] However, when using a brace to fix and support the patient's upper limb, in order to prevent the limb from slipping off the brace, the patient usually places their upper limb on the top of the brace, and then medical staff need to operate multiple restraint straps in sequence to fix the limb to the brace. This not only increases the frequency of repetitive work for medical staff and affects the efficiency of positioning the limb to the brace, but also causes marks at the point where the limb and the restraint straps fit together during long-term use of the brace, increasing the patient's discomfort and affecting blood circulation in the limb. Summary of the Invention
[0004] In view of this, the present invention provides an adjustable upper limb care bracket, which utilizes the gravity of the affected limb itself to automatically drive the positioning auxiliary mechanism, causing the two clamping positioning plates to slide inward synchronously, thereby achieving automatic clamping and positioning of the affected limb. This not only increases the contact area between the affected limb and the clamping positioning plates during positioning, reducing the formation of ligature marks and ensuring blood circulation in the affected limb during positioning, but also improves the positioning efficiency of the affected limb, reduces the frequency of repetitive work for medical staff, and further enhances the ease of operation of this bracket in practical applications.

[0037] Among them, the bottom end face of the assist bracket 601 is vertically fixedly connected to the drive rack 6011;
[0038] The inner side of the double-ended lead screw 602 is coaxially fixedly connected to a guide shaft 603; the guide shaft 603 has a polygonal shaft structure; a drive gear 604 is slidably arranged at the outer end of the guide shaft 603; the drive gear 604 meshes with the drive rack 6011, and the drive rack 6011 and the drive gear 604 together constitute a gear and rack transmission mechanism.
[0039] The positioning auxiliary mechanism also includes: a traction operation frame 608, which is rotatably mounted on the outside of the drive gear 604, and the traction operation frame 608 has an L-shaped frame structure; the traction operation frame 608 is slidably mounted on the outside of the bottom end face of the force monitoring plate 5.
[0040] The positioning auxiliary mechanism also includes: a transmission auxiliary frame 605, a limiting shaft 606, and a spiral elastic element 607. There are two transmission auxiliary frames 605, which are threadedly connected to the left and right sides of the double-ended lead screw 602, respectively. There are two limiting shafts 606, which are fixedly connected to the outer side of the top end face of the two transmission auxiliary frames 605, respectively. The limiting shafts 606 are slidably connected to the clamping positioning plate 6. There are two spiral elastic elements 607, which are fixedly connected between the two ends of the double-ended lead screw 602 and the positioning frame 4, respectively.
[0041] The force monitoring mechanism also includes: a connecting shaft 501, a striking ball head 502, and a warning auxiliary ring 503; the connecting shaft 501 is fixedly connected to the center of the inner side of the force monitoring plate 5, and the connecting shaft 501 is rotatably connected to the positioning frame 4; there are multiple striking balls 502, which are elastically connected to both ends of the connecting shaft 501 in a circumferential array; there are two warning auxiliary rings 503, which are respectively set on the outer side of the striking ball head 502 on the same side; the warning auxiliary ring 503 is fixedly connected to the positioning frame 4.

[0043] The specific usage and function of this embodiment are as follows:
[0044] In use, during the outward sliding of the traction frame 608, the drive gear 604 slides synchronously. After the drive gear 604 slides outward, it no longer meshes with the drive rack 6011. At this time, when the double-ended lead screw 602 is manually rotated, the transmission auxiliary frame 605 pushes the two clamping positioning plates 6 to slide synchronously inward or outward. After adjusting the clamping positioning plates 6 to a suitable position according to the thickness of the patient's upper limb, the drive gear 604 is reset, so that the drive gear 604 meshes with the drive rack 6011. The patient's upper limb is placed between the two clamping positioning plates 6. Due to the gravity of the affected limb, the assistive support 601 slides downward. During the process, the drive rack 6011 drives the drive gear 604 and the double-ended lead screw 602 to rotate synchronously. During the rotation of the double-ended lead screw 602, the two transmission auxiliary frames 605 push the two clamping positioning plates 6 to slide inward synchronously. During the synchronous inward sliding of the two clamping positioning plates 6, automatic clamping of both sides of the affected limb is achieved. When the patient's upper limb becomes fatigued due to maintaining one movement for a long time, causing the patient to raise one side of the upper limb or exert excessive force, the force monitoring plate 5 and the connecting shaft 501 rotate synchronously. During the rotation of the connecting shaft 501, the striking ball head 502 strikes the warning auxiliary ring 503 to produce a sound, automatically warning the patient and avoiding a series of unnecessary troubles caused by excessive force of the upper limb.
[0045] Example 2: Please refer to Figures 6 to 9 As shown:
[0046] Based on Embodiment 1, the lifting auxiliary mechanism includes: a drive screw 3.
[0047] The mounting bracket 1 has an installation auxiliary frame 101 fixedly connected to its bottom end face. The installation auxiliary frame 101 is an L-shaped frame structure. The lower end of the inner side of the installation auxiliary frame 101 is threadedly connected to a positioning operation component 102. The top end face of the positioning operation component 102 is coaxially fixedly connected to a resistance plate 103.
[0048] There are two drive screws 3, which are rotatably connected to the front and rear sides of the upper end of the mounting bracket 1 respectively; the drive screws 3 are threadedly connected to the lifting control frame 2.
[0049] A transmission pulley 302 is coaxially fixedly connected to the bottom end face of the drive screw 3; a transmission belt 303 is wound around the outside of the transmission pulley 302.
[0050] The lifting auxiliary mechanism also includes: a control adjustment shaft 304 and a bevel gear transmission assembly 305. The control adjustment shaft 304 is vertically rotatably mounted on the outer end of the front drive screw 3; the bevel gear transmission assembly 305 is mounted between the control adjustment shaft 304 and the front drive screw 3.
[0051] The massage assist mechanism includes: a drive shaft 7 and an eccentric wheel 701. There are two drive shafts 7, which are rotatably connected to the inner ends of two clamping and positioning plates 6 respectively. The outer ends of the drive shafts 7 are coaxially fixedly connected to the outer side of the micro drive motor shaft.

[0052] The specific usage and function of this embodiment are as follows:
[0053] In use, the present invention involves securing the mounting bracket 1 and the mounting auxiliary frame 101 to one side of the bed frame or connecting frame. As the positioning operation component 102 rotates, the mounting bracket 1 is positioned on the bed frame or connecting frame. During the rotation of the control adjustment shaft 304, the bevel gear transmission assembly 305 drives the front drive screw 3 to rotate. As the front drive screw 3 rotates, the transmission pulley 302 and transmission belt 303 drive the two drive screws 3 to rotate synchronously. This synchronous rotation of the two drive screws 3 controls the lifting and lowering of the lifting control frame 2, meeting the needs for different limb support heights under various conditions. When the drive motor starts and the two drive shafts 7 rotate in opposite directions, the eccentric wheel 701 rotates synchronously. This rotation of the eccentric wheel 701 provides automatic massage to the affected limb, alleviating discomfort caused by the patient maintaining one position for extended periods and accelerating blood circulation in the affected limb.
